In counseling parents blood pressure medication pictures order 10mg benicar fast delivery, we stress that within these parameters blood pressure 50 over 0 generic benicar 10 mg free shipping, delivery room resuscitation alone has a high (but not absolute) chance of success prehypertension pregnancy cheap benicar 40 mg visa, but that this in no way guarantees survival beyond these early minutes. Studies have confirmed our experience that decisions based on the apparent condition at birth are unreliable in terms of viability or long-term outcome. We also note that the initiation of intensive care in no way mandates that it be continued if it is later determined to be futile or very likely to result in a poor long-term outcome. Parents are counseled that the period of highest vulnerability may last several weeks in infants of lowest gestational ages. Once all these components are discussed, we make a recommendation regarding an approach to initial resuscitation. If parents disagree with this recommendation, we first attempt to resolve differences by ensuring that they understand the medical information, and we understand their views and concerns, as well as their central role in determining appropriate care for their child. Almost always, a consensus on a plan of care is reached, but if an impasse continues, we seek consultation from the institutional Ethics service (see Chap. Care decisions and parental expectations must be based not only on estimates of survival, but on information about likely short- and long-term prognosis. Before delivery, particular attention is paid to the problems that might appear at birth or shortly thereafter. We also inform parents of the likelihood of infection at birth as well as our plan to screen for it and begin empiric antibiotic therapy while final culture results are pending. During prenatal consultation, we generally avoid giving parents detailed information on every potential sequelae of extreme prematurity because they may be too overwhelmed to process extensive information during this time. We make a point of briefly discussing the risks of retinopathy of prematurity and subsequent visual deficits and the need for hearing screening and the potential for hearing loss. These complications are not noted until late in the hospital course, but we find that giving parents some perspective on the entire hospitalization is helpful to them. In most instances, parents are the best surrogate decision makers for their child. We believe that, within each institution, there should be a uniform approach to parental demands for attempting or withholding resuscitation at very low gestational ages. The best practice is to formulate decisions in concert with parents, after providing them with clear, realistic, and factual information about the possibilities for success of therapy and its long-term outcome. During the consultation, the neonatologist should try to understand parental wishes about resuscitative efforts and subsequent support, especially when chances for infant survival are slim. When counseling parents around an expected birth at 24 weeks, we specifically offer them the choice of limiting delivery room interventions to those designed to ensure comfort alone if they feel that the prognosis appears too bleak for their child. We encourage them to voice their understanding of the planned approach and their expectations for their soon-to-be-born child. We reassure them that the strength of their wishes does help guide caregivers in determining whether and how long to continue resuscitation attempts. Through this approach, we clarify for parents their role in decision making as well as the limitations of that role. At 25 weeks and above, in the absence of other factors, we very strongly advocate for attempting resuscitation and make this clear to parents. The approach to resuscitation is similar to that in more mature infants (see Chap. Conventional practice has been to place the infant under a preheated warmer, quickly dry the baby, and remove the wet toweling. Care must be taken to avoid overheating the baby, especially when more than one of these modalities is employed. Blended oxygen and air should be available to help avoid prolonged hyperoxia after the initial resuscitation, and it should be used in conjunction with pulse oximetry, using a probe placed on the right upper ("preductal") extremity. Studies have demonstrated that a blend of oxygen and air is preferable over either one alone, but the optimal concentration has not yet been identified; we have chosen to start with 60% oxygen and titrate the concentration based on measured oxygen saturation. We use the saturation targets identified for all babies the first several minutes (see Table 5. If the neonate cries vigorously at birth, we administer blow-by blended oxygen if required on the basis of saturation, and observe the infant for signs of distress. Many of these infants require bag-and-mask ventilation because of apnea or ineffective respiratory drive. In studies comparing these modalities, there were no differences in survival or incidence of chronic lung disease. If the infant is not breathing spontaneously, positive pressure ventilation must be started; provision of adequate support will result in or maintain a normal heart rate. If positive pressure ventilation is used, moderately high-inflating pressures may be necessary for the initial breaths of an infant whose lungs are deficient in surfactant. Within one or two breaths, the peak pressure should be rapidly lowered to minimize lung injury, with the goal of using the smallest tidal volumes and peak pressure possible while still adequately ventilating the infant. These infants usually require continued respiratory support and do benefit from early application of end-expiratory pressure; our practice is to provide this via endotracheal intubation and ventilation shortly after birth. While commonly practiced in many institutions, administration of exogenous surfactant therapy before the first breath has not yet been proved to be more beneficial than administration after initial stabilization of the infant. Exogenous surfactant may be safely administered in the delivery room once correct endotracheal tube position has been confirmed clinically. The pediatrician should assess the response to resuscitation and gauge the need for further interventions. If the infant fails to respond, the team should recheck that all supporting measures are being effectively administered. If, on the other hand, there is no positive response to resuscitation after a reasonable length of time, we consider limiting support to comfort measures alone. Within practical limits, we encourage as much interaction between baby and the parents in the delivery room (while in the transport incubator) to enhance the beginning of parentnfant interaction. As soon as possible, the unit is closed to function as an incubator for continued care. Humidity is maintained at 70% for the first week of life, and 50% to 60% thereafter up to 32 weeks corrected gestation. In addition to reducing insensible fluid losses and thereby simplifying fluid therapy, the use of incubators aids in reducing unnecessary stimulation and noise experienced by the baby. Large fluid losses, balances between fluid intake and blood glucose levels, delicate pulmonary status, and the immaturity and increased sensitivity of several organ systems all require close monitoring. The first several days after birth, but in particular the first 24 to 48 hours, are the most critical for survival. Infants who require significant respiratory, cardiovascular, and/or fluid support are assessed continuously, and their chances for ongoing survival are evaluated as part of this process. If caregivers and the parents determine that death is imminent, continued treatment is futile, or treatment is likely to result in survival of a child with profound neurologic impairment, we recommend the withdrawal of ventilator and other invasive support and redirection of care to comfort measures and support of the family.

A transitional object such as a blanket or stuffed animal can be used to pulse pressure 65 buy benicar 10mg lowest price promote positive sleep associations and encourage self-soothing blood pressure 4080 buy benicar in united states online. The bedtime should be set early enough to blood pressure 9862 purchase benicar 10mg otc allow for sufficient nighttime sleep, and both bedtime and morning wake time should be consistent, including on weekends. Televisions and other electronic devices should be removed from the bedroom because these can lead to delayed sleep onset and maladaptive sleep associations. Sleep-onset association disorder in infancy usually can be prevented by parental understanding of infant sleep physiology, developmentally appropriate expectations, and planning the infant sleep environment to coincide with family needs. It is recommended that infants be put in bed drowsy, but still awake, after they have had a diaper change, food, and comfort. Some toleration of infant crying is required for the infant to achieve self-regulation of sleep. It is important for parents to understand that it is normal for their infant to wake frequently for the first 6 weeks before settling into a routine of waking every 3 to 4 hours for feeding. Infants typically do not sleep through the night before 6 months of age, and some do not sleep through the night before 12 to 18 months of age. Proactively considering the desirability of bed sharing allows parents to be in control rather than ceding control to the young child. Behavioral interventions comprise the mainstay of treatment for behavioral sleep disorders. In addition to meticulous attention to sleep hygiene and bedtime practices, difficulty falling asleep and bedtime resistance in young children are treated by specific behavioral strategies. Graduated extinction involves waiting successively longer periods of time before briefly checking on the child. Both methods are effective in decreasing bedtime resistance and enabling young children to fall asleep independently. Positive reinforcement strategies can also be used in preschool-aged and Complications the most obvious and serious complication associated with childhood sleep disorders is impairment of cognitive ability and emotional regulation. This impairment puts children at risk for school failure, family difficulties, and social problems. It is likely that sleep-deprived children are at increased risk for acute illness and psychiatric disorders. While transient symptoms, as "signals of distress," are responsible for up to 50% of outpatient visits in the pediatric age group, somatoform disorders represent only the severe end of this continuum. Somatization is often associated with psychosocial stress and often persists beyond the acute stressor, leading to the belief by the child and the family that the correct medical diagnosis has not yet been found. A somatization disorder occurs in as many as 10% to 20% of first-degree relatives and has a higher concordance rate in monozygotic twin studies. Lifetime prevalence of somatoform disorders is 3%, and that of subclinical somatoform illness is as high as 10%. Adolescent girls tend to report nearly twice as many functional somatic symptoms as adolescent boys, whereas prior to puberty the ratio is equal. Affected children are more likely to have difficulty expressing emotional distress, come from families with a history of marital conflict, child maltreatment (including emotional, sexual, physical abuse), or history of physical illness. Depression is a common comorbid condition and frequently precedes the somatic symptoms. The diagnostic criteria for somatoform disorders are established for adults and need additional study in pediatric populations. Somatization disorder involves multiple unexplained physical complaints, including pain, gastrointestinal, sexual, and pseudoneurologic symptoms not caused by known mechanisms. Given the requirement for at least one sexual or reproductive symptom, the diagnosis is unusual in children and the onset is common during adolescence. Undifferentiated somatoform disorder (Table 16-3) includes one or more unexplained physical complaints accompanied by functional impairment that last for at least 6 months. Conversion disorder involves symptoms affecting voluntary motor or sensory function and is suggestive of a neurologic illness in the absence of a disease process (Table 16-4). Adjustment difficulties, recent family stress, unresolved grief reactions, and family psychopathology occur at a high frequency in conversion symptoms. There are four subtypes of conversion disorder based on whether the symptoms presented are primarily motor, sensory, nonepileptic (seizures), or mixed. Presenting symptoms follow the psychological stressor by hours to weeks and may cause more distress for others than for the patient. This seeming lack of concern regarding potentially serious symptoms is referred to as la belle indifference. Patient consciously recognizes symptom complex as factitious but is often psychologically disturbed so that unconscious factors also are operating. Four pain symptoms: pain related to at least four different sites or functions. Two gastrointestinal symptoms: at least two gastrointestinal symptoms other than pain. One sexual symptom: at least one sexual or reproductive symptom other than pain. One pseudoneurologic symptom: at least one symptom or deficit suggesting a neurologic condition not limited to pain (conversion symptoms such as impaired coordination or balance, paralysis or localized weakness, difficulty swallowing or lump in throat, aphonia, urinary retention, hallucinations, loss of touch or pain sensation, double vision, blindness, deafness, seizures; dissociative symptoms such as amnesia; or loss of consciousness other than fainting) Either (1) or (2) 1. After appropriate investigation, each of the symptoms is not fully explained by a known general medical condition or the direct effects of a substance. When there is a related general medical condition, the physical complaints, social or occupational impairment are in excess of what is expected from the history, physical examination, or laboratory findings. After appropriate investigation, the symptoms cannot be fully explained by a known general medical condition or the direct effects of a substance. When there is a related general medical condition, the physical complaints, social, or occupational impairment is in excess of what is expected from the history, physical examination, or laboratory findings. The symptom is not intentionally produced or feigned (factitious disorder, malingering). Symptoms are often self-limited but may be associated with chronic sequelae, such as contractures or iatrogenic injury. Falling out syndrome (falling down with altered consciousness) is common in several cultures throughout the world, including the United States. Symptoms are Chapter 16 Table 16-4 Criteria for Diagnosis of Conversion Disorder u Somatoform Disorders, Factitious Disorders, and Malingering 53 Table 16-5 Criteria for Diagnosis of Pain Disorder A. One or more symptoms affect voluntary motor or sensory function, suggesting a neurologic or other general medical condition. Psychological factors are judged to be associated with the symptom or deficit because the initiation or exacerbation is preceded by conflicts or other stressors. After appropriate investigation, the symptom cannot be fully explained by a general medical condition, by the direct effects of a substance, or as a culturally sanctioned behavior or experience. The symptom causes clinically significant distress or impairment in social, occupational, or other function or warrants medical evaluation. The symptom is not limited to pain or sexual dysfunction, does not occur exclusively during the course of somatization disorder, and is not better accounted for by another mental disorder.

Chapter 21 Ectopic Gestation 309 Ultrasound Ultrasound in cervical pregnancy shows: n n n n n n n A small amount of fluid medium to blood pressure quizzes order 10 mg benicar amex be transferred heart attack low vs diamond 10mg benicar. Absence of sliding sign-the pressure over the cervix causes sliding down of the gestational sac in a miscarriage arrhythmia heart episode benicar 20mg for sale, whereas the cervical pregnancy remains static, since it is attached to the cervix. Caesarean Scar Ectopic Pregnancy Caesarean scar ectopic pregnancy is recently reported in 6% of ectopic pregnancies. The ultrasound shows an empty uterus and cervix and the gestational sac is attached low to the lower segment caesarean scar. The gestation sac is embedded in the myometrium and fibrosis of the caesarean scar. Treatment Treatment consists of ligating the uterine vessel vaginally, suction evacuation and tamponade by inserting a distended Foley catheter in the cervical canal for 24 h. Uterine artery embolization has been attempted to reduce blood loss, prior to evacuation of cervical and caesarean scar pregnancy; this controls the bleeding. Ultrasound Ultrasound shows: n n n Gestational sac located over the lower anterior uterine segment. Surgery-Suction curettage may be risky even under ultrasonic guidance and the risk of caesarean scar rupture remains. In a young woman desirous of childbearing, resection and suturing of scar can be done but the risk of scar rupture in subsequent pregnancy is considerable. There is an increased risk of repeat scar ectopic pregnancy as well as placenta accreta. The treatment is preferably laparoscopic minimal invasive surgery, allowing uterine pregnancy to grow. Recurrent pregnancy remains a threat to a woman with one ectopic pregnancy, and she needs good monitoring in subsequent pregnancies. Early diagnosis is the key to successful medical and minimal conservative surgery; it reduces mortality. Ectopic pregnancy has to be considered when a patient presents with bizarre clinical picture. Persistent trophoblastic residual tissue and recurrent ectopic pregnancy requires further improvement in conservative management. With greater awareness in high-risk cases and better screening procedures, life-threatening ectopic pregnancy has changed to a benign condition in asymptomatic women, allowing conservative management and improving subsequent fertility outcome. Morbidity includes: n n n n n n n Infertility Recurrent ectopic pregnancy Pelvic adhesions and chronic pelvic pain. A young primigravida presents with 2 months amenorrhoea, slight abdominal pain and vaginal bleeding. A woman presents with 3 months amenorrhoea, with fainting attacks and acute abdominal pain. Key Points n n n n n n Of all the ectopics, tubal pregnancy is the most common and its aetiological factors are well defined. While an acute ectopic pregnancy is life-threatening and requires an emergency surgery, subacute and chronic ectopic pregnancy require investigations to confirm the diagnosis. Conservative surgery and medical therapy can salvage the fallopian tube for future fertility. Cervical pregnancy, pregnancy in a rudimentary horn, caesarean scar pregnancy and abdominal pregnancy are rare. Heterotopic pregnancy is gaining importance with successful assisted reproductive technology and its management requires conservation of uterine pregnancy.

Sengupta, Chattopadhyay, Varrma: Textbook of Gynaecology for Postgraduates and Practitioners, Elsevier, 2007. The tumour sometimes invades the wall of the uterus and the surrounding structures, when it is called an invasive mole. Some immigrants from Southeast Asia to a developed country lose the potential to develop hydatidiform mole once they settle down in the new environment. This proves that the condition is not racial, but may be related to geographical and environmental influences. Vitamin A, b-carotene and folic acid deficiency in the diet are also implicated in the occurrence of trophoblastic disease. Women belonging to blood group A are susceptible to this disease, but the reason is not known. In contrast to a complete mole, maternal age and nutrition do not appear to influence the incidence of a partial mole. The diagnosis of complete and partial mole is based on morphological, histological and karyotype findings (Table 22. Morbid Anatomy A complete hydatidiform mole resembles bunches of grapelike vesicles, pearly white in colour and translucent, containing watery fluidures 22. The vesicles vary in size from a few millimetres up to 2 cm in diameter and are attached to the main stalk by thin pedicles. Histologically, the disease is characterized by (i) hydropic degeneration and swelling of the villous stroma, (ii) absence of villous blood vessels and (iii) proliferation of both the trophoblastic epithelia to a varying degree. Malignant potential Rare epithelial cells whose nuclei are hyperchromatic and actively mitotic. Irrespective of trophoblastic cell proliferation, it is the preservation of a villous structure that determines the benign nature of the trophoblastic diseaseure 22. In a very early pregnancy, it is difficult to differentiate between a molar pregnancy and a missed abortion. A partial mole resembles the placenta, but contains a few vesicles on its maternal surface. The fetus most often shows gross malformation, intrauterine growth retardation and in utero death. The average gestational age when a partial mole is diagnosed is at a later date than a complete mole, around 246 weeks of pregnancy. The undue enlargement seen in a complete mole is rarely observed in a partial mole, and it may be of a normal size or smaller for the gestational period on account of intrauterine fetal growth retardation. Eighty per cent of hydatidiform moles resolve by treatment, 15% persist as persistent or residual mole and 5% develop into choriocarcinoma. Chemotherapy is usually effective, but hysterectomy may be required to control bleeding if perforation occurs. Placental Site Trophoblastic Tumour It constitutes 1% of all trophoblastic diseases. Placental site trophoblastic tumour arises from the placental bed trophoblast and invades the myometrium.

Chelation therapy with deferoxamine or deferasirox should start when laboratory evidence of iron overload (hemochromatosis) is present and before there are clinical signs of iron overload (nonimmune diabetes mellitus, cirrhosis, heart failure, bronzing of the skin, and multiple endocrine abnormalities). Hematopoietic stem cell transplantation in childhood, before organ dysfunction induced by iron overload, has had a high success rate in -thalassemia major and is the treatment of choice. The specific hemoglobin phenotype must be identified because the clinical complications differ in frequency, type, and severity. As the oxygen is extracted and saturation declines, sickling may occur, occluding the microvasculature. This sickling phenomenon is exacerbated by hypoxia, acidosis, fever, hypothermia, and dehydration. A child with sickle cell anemia is vulnerable to life-threatening infection by 4 months of age. Splenic dysfunction is followed, eventually, by splenic infarction, usually by 2 to 4 years of age. The loss of normal splenic function makes the patient susceptible to overwhelming infection by encapsulated organisms, especially Streptococcus pneumoniae and other pathogens (Table 150-8). Current precautions to prevent infections include prophylactic daily oral penicillin begun at diagnosis and vaccinations against pneumococcus, Haemophilus influenzae type b, hepatitis B virus, and influenza virus. Manifestations of chronic anemia include jaundice, pallor, variable splenomegaly in infancy, a cardiac flow murmur, and delayed growth and sexual maturation. In two different clinical situations, an acute, potentially life-threatening decline in the hemoglobin level may be superimposed on the chronic compensated anemia. The spleen is moderately to markedly enlarged, and the reticulocyte count is elevated. Simple transfusion therapy is indicated for sequestration and aplastic crises when the anemia is symptomatic. Vasoocclusive painful events may occur in any organ of the body and are manifested by pain and/or significant dysfunction (see Table 150-8). The acute chest syndrome is a vasoocclusive crisis within the lungs with evidence of a new infiltrate on chest radiograph. The patient may first complain of chest pain but within a few hours develops cough, increasing respiratory and heart rates, hypoxia, and progressive respiratory distress. Physical examination reveals areas of decreased breath sounds and dullness on chest percussion. Incentive spirometry may help reduce the incidence of acute chest crisis in patients presenting with pain in the chest or abdomen. The pain usually localizes to the long bones of the arms or legs but may occur in smaller bones of the hands or feet in infancy (dactylitis) or in the abdomen. Vasoocclusive crises within the femur may lead to avascular necrosis of the femoral head and chronic hip disease. Treatment of pain crises includes administration of fluids, analgesia (usually narcotics and nonsteroidal anti-inflammatory drugs), and oxygen if the patient is hypoxic. Although pain is often impossible to quantitate, the risk for drug dependency is highly overrated, and appropriate use of analgesics is necessary. A significant change in school performance or behavior has been associated with silent stroke. The diagnosis of hemoglobinopathies is made by identifying the precise amount and type of hemoglobin using hemoglobin electrophoresis, isoelectric focusing, or high-performance liquid chromatography. Every member of an at-risk population should have a precise hemoglobin phenotype performed at birth (preferably) or during early infancy. Hydroxyurea, which increases hemoglobin F, decreases the number and severity of vasoocclusive events and frequency of acute chest syndrome in children as early as 1 year of age. Hematopoietic stem cell transplantation, using a haploidentical sibling match, has cured many children with sickle cell disease. The most common variant with normal activity is termed type B and is defined by its electrophoretic mobility. The approximate gene frequencies in African Americans are 70% type B, 20% type A, and 10% type A Therapeutic steps for priapism include the administration of oxygen, fluids, analgesia, and transfusion when appropriate to achieve a hemoglobin S less than 30% (often by partial exchange transfusion). Fluid management requires recognition that renal medullary infarction results in loss of the ability to concentrate urine. These events may present as the sudden onset of an altered state of consciousness, seizures, or focal paralysis. Silent stroke, which is defined as evidence of cerebral Chapter 150 and Oriental Jews, and Arabs is termed the Mediterranean variant and is associated with chronic hemolysis and potentially life-threatening hemolytic disease. Heterozygous females who have randomly inactivated a higher percentage of the normal gene may become symptomatic, as may homozygous females with the Avariant (0. Individuals with the Avariant have normal hemoglobin values when well, but develop an acute episode of hemolysis triggered by serious (bacterial) infection or ingestion of an oxidant drug. Clinically evident jaundice, dark urine resulting from bilirubin pigments, hemoglobinuria when hemolysis is intravascular, and decreased haptoglobin levels are common during hemolytic episodes. Early on, the hemolysis usually exceeds the ability of the bone marrow to compensate, so the reticulocyte count may be low for 3 to 4 days. Maintaining hydration and urine alkalization protects the kidneys against damage from precipitated free hemoglobin. Hemolysis is prevented by avoidance of known oxidants, particularly long-acting sulfonamides, nitrofurantoin, primaquine, dimercaprol, and moth balls (naphthalene). Fava beans (favism) have triggered hemolysis, particularly in patients with the Mediterranean variant. Some individuals have a true deficiency state, and others have abnormal enzyme kinetics. Pyruvate kinase deficiency is usually an autosomal disorder, and most children who are affected (and are not products of consanguinity) are double heterozygotes for two abnormal enzymes. Hemolysis is not aggravated by oxidant stress due to the profound reticulocytosis in this condition. Most patients have amelioration of the anemia and a reduction of transfusion requirements after splenectomy. The biochemical basis of hereditary spherocytosis and hereditary elliptocytosis are similar. Both conditions appear to have a defect in the protein lattice (spectrin, ankyrin, protein 4. In hereditary spherocytosis, pieces of membrane bud off as microvesicles because of abnormal vertical interaction of the cytoskeletal proteins and uncoupling of the lipid bilayer from the cytoskeleton.

Initial side effects blood pressure just before heart attack buy generic benicar on-line, such as nausea (pills should be taken at night to reduce this), breast tenderness, and breakthrough bleeding (especially if pills are missed), are common and usually transient. Because unintended pregnancy can be associated with significant psychosocial morbidity for the mother, father, and child, prevention should be a primary goal. All methods of contraception significantly reduce the risk of pregnancy when used in a consistent and correct fashion. Hypertension (systolic 160 mm Hg or diastolic 100 mm Hg) Current or history of venous thromboembolism Ischemic heart disease History of cerebrovascular accident Complicated valvular heart disease (pulmonary hypertension, atrial fibrillation, history of subacute bacterial endocarditis) Migraine with focal neurologic symptoms Breast cancer (current) Diabetes with retinopathy/nephropathy/neuropathy Severe cirrhosis Liver tumor (adenoma or hepatoma) Abstinence Abstaining from sexual intercourse is the most commonly used and most effective form of adolescent birth control. Adolescents who choose to be sexually active should be offered birth control, because there is a 70% chance of pregnancy in 1 year of regular, unprotected intercourse. Management of Missed Combined Oral Contraceptives Take 1 active pill as soon as possible. Progestogen-only contraception is associated with menstrual irregularities (70% amenorrhea and 30% frequent menstrual bleeding). Medroxyprogesterone acetate (Depo-SubQ Provera 104) is designed for subcutaneous use every 12 to 14 weeks and may be self-administered with minimal training. An implant containing the progestin etonogestrel (Implanon) is now available on the U. These forms of contraception are user- and coital-independent and reduce failure secondary to missed doses. The levonorgestrel-releasing intrauterine system is highly effective for up to 5 years while decreasing bleeding and dysmenorrhea, even causing amenorrhea. Emergency Postcoital Contraception Emergency postcoital contraception should be discussed at every visit. A prescription should be given in advance of need when no over-the-counter access is available. Emergency contraception reduces the risk of pregnancy after unprotected intercourse if used within 5 days, although efficacy is greatest when used as early as possible. Other indications and contraindications to emergency postcoital contraception are listed in Table 69-7. Mifepristone is also an effective postcoital contraceptive; however it is not approved for this use in the United States. Adolescents should be taught the appropriate response to missed doses (Table 69-6). Health care providers usually suggest the use of additional contraception in the first month. It is supplied in packages of 28 tablets, each containing norethindrone with no hormone-free interval. It prevents pregnancy through reduced volume, increased viscosity, and altered molecular structure of cervical mucus, resulting in little or no sperm penetration. In addition, endometrial changes reduce the potential for implantation, and ovulation is partially or completely suppressed. Approximately 40% of women using progestogen-only contraceptives continue to ovulate. Progestogen-only contraception is indicated for women who have a contraindication to estrogen-based contraceptives (see Table 69-4) or have estrogen-related side effects. Contraceptive Vaginal Ring the contraceptive vaginal ring (NuvaRing) is a flexible, Silastic ring. Contraceptive Patch the contraceptive patch (norelgestromin [Evra]) is a 25-cm2 pink patch that is applied, usually on the buttocks, for 1 week followed by removal and application of a new patch for a total of 3 weeks of patch use, then a patch-free week for a withdrawal bleed. Adolescents tend to have unpredictable cycles and consequently less predictable ovulation, so it is difficult to determine with any accuracy a time of the month that can be considered completely safe. Oral and Anal Sex Some adolescents engage in oral or anal sex because they believe that it eliminates the need for contraception. The female condom (Reality) is an additional barrier method made of polyurethane that affords females more control, but adolescents usually do not consider it aesthetically pleasing. Sponge, Caps, and Diaphragm the vaginal sponge (Protectaid) is a spermicide-impregnated synthetic sponge that is effective for 24 hours of intercourse. The FemCap is a silicone cap fitted by a health care provider and then placed on the cervix by the user before intercourse. The diaphragm is fitted by a health care provider but is technically simpler to use than the cap because the edges go into the vaginal fornices. To be effective, the diaphragm should be used with spermicide applied to the cervical side and along the rim. All of these methods need to be left in place for 6 hours after the last act of intercourse for optimal efficacy. Coitus Interruptus Withdrawal is a common method of birth control used by sexually active adolescents, but it is ineffective because sperm are released into the vagina before ejaculation, and withdrawal may occur after ejaculation has begun. Rhythm Method (Periodic Coital Abstinence) the rhythm method is the practice of periodic abstinence just before, during, and just after ovulation. Almost half of rape victims are adolescents, and the perpetrator is known in 50% of cases. The history should include details of the sexual assault, time from the assault until presentation, whether the victim cleaned herself, date of last menstrual period, and previous sexual activity, if any. For optimal results, forensic material should be collected within 72 hours of the assault. Clothes, especially undergarments, need to be placed in a paper bag for drying (plastic holds humidity, which allows organisms to grow, destroying forensic evidence). The patient should be inspected for bruising, bites, and oral, genital, and anal trauma. Specimens should be obtained from the fingernails, mouth, vagina, pubic hair, and anus. A wet mount of vaginal fluids shows the presence or absence of sperm under the microscope. All materials must be maintained in a "chain of evidence" that cannot be called into question in court. A single oral dose of cefixime, 400 mg, and azithromycin, 1 g, treats Chlamydia, gonorrhea, and syphilis. An alternative regimen is a single intramuscular dose of ceftriaxone, 125 mg, with a single oral dose of azithromycin, 1 g. For prophylaxis against bacterial vaginosis and Trichomonas, a single oral dose of metronidazole, 2 g, is recommended. Longterm sequelae are common; patients should be offered immediate and ongoing psychological support, such as that offered by local rape crisis services. The diagnosis in young adolescents (pregrowth spurt, premenstrual) may not follow the typical diagnostic criteria (Table 70-1). The female-to-male ratio is approximately 20:1, and the condition shows a familial pattern.

Draw a serum level before the first maintenance dose to hypertension updates 2014 cheap benicar american express assess initial phenobarbital concentration hypertension diabetes purchase cheap benicar on line. Phenobarbital is the drug of choice if the infant is thought to blood pressure chart journal generic 40mg benicar with mastercard be withdrawing from a nonnarcotic drug or from multiple drug use. Morphine and phenobarbital can be initiated together for infants withdrawing from multiple drugs and may lessen the symptoms compared with single medical therapy. Morphine should be withdrawn first and the infant observed for 2 to 3 days off morphine and on phenobarbital alone. This may allow the discharge of an infant home in the setting of an appropriate environment, with phenobarbital being prescribed. The infant can be allowed to outgrow the dose at home or the dose decreased under the care of the pediatrician. Chlorpromazine is no longer used by us because of its unacceptable side effects, including tardive dyskinesia. It is useful to control the vomiting and diarrhea that sometimes occur in withdrawal. It is now considered safe for methadone-treated mothers to breast-feed if there are no other contraindications. The maintenance dose is the total methadone dose given over the previous 24 hours divided by 2 and given every 12 hours. Weaning can then be attempted by giving methadone every 12 hours, and then every 24 hours at the last dose used. Breakthrough symptoms, including seizures, respiratory depression, and bradycardia have been seen during use of diazepam. The sodium benzoate included in parenteral diazepam may interfere with the binding of bilirubin to albumin. The manufacturer warns that the safety and efficacy of injectable diazepam have not been established in the newborn (see Appendix A). The parenteral preparation of lorazepam contains benzyl alcohol and polyethylene glycol. Irritability, tremors, General Newborn Condition 149 and disturbance of sleeping patterns may last for up to 6 months and should not be a reason for continuing medication. Cocaine has a potent anorexic effect and may cause prenatal malnutrition, an increased rate of premature labor, spontaneous abortion, placental abruption, fetal distress, meconium staining, and low Apgar scores. Cocaine increases catecholamines, which can increase uterine contractility and cause maternal hypertension and placental vasoconstriction with diminished uterine blood flow and fetal hypoxia. The following are congenital anomalies associated with cocaine use during pregnancy: cardiac anomalies; genitourinary malformations; intestinal atresias; microcephaly with or without growth retardation; perinatal cerebral infarctions, usually in the distribution of the middle cerebral artery with resultant cystic lesions; early-onset necrotizing enterocolitis; and retinal dysgenesis and retinal coloboma. Many of these findings are also true of tobacco use, and because many crack cocaine users also smoke cigarettes, it may be difficult to identify which defects are specific to cocaine. When the pregnant cocaine abuser also uses other drugs, the neonate may have more severe withdrawal; in this case, we use phenobarbital. If symptomatic treatment is not adequate, use phenobarbital or lorazepam for sedation. Long-term disabilities such as attention deficits, concentration difficulties, abnormal play patterns, and flat, apathetic moods have been reported. Some believe that the neurologic and cognitive outcomes of cocaine exposure are unclear because standard methods of measuring infant neurologic and behavioral functions are difficult to quantify. It is also difficult to extricate the effects of cocaine use from the effects of lack of prenatal care, polydrug use, smoking, and the increased risks associated with a drug-using lifestyle. Convulsions have been seen both in infants of breastfeeding mothers using cocaine and in infants exposed to passive crack smoke inhalation. Because cocaine and its metabolites can be found in breast milk for up to 60 hours after use, breastfeeding is not recommended. Teratogenic studies are confounded by other risk factors, but there is no established safe level of ethanol use in pregnancy. Symmetric growth retardation can occur in utero, the extent of which depends on the dose and duration of maternal use and on other factors such as concomitant tobacco or other drug use and overall nutrition. Smoking by pregnant women is associated with a higher rate of spontaneous abortions. Placental vascular resistance is increased as a consequence of the effects of nicotine, with resultant chronic ischemia and hypoxia. The most pronounced effects of smoking on fetal growth occur after the second trimester. No association has been found between maternal smoking during pregnancy and congenital anomalies. There may be decreased fetal growth but no increase in major or minor morphologic anomalies. However, the drug may persist in milk for days after exposure and become concentrated with long-term use. Some have found low Brazelton scores in these neonates and poor McCarthy scores on follow-up. Its abuse potential lies in the fact that it provides a euphoric rush after being inhaled (smoked), snorted, or injected. Withdrawal symptoms from methamphetamines, are difficult to tease out, as the drug is commonly used in conjunction with other drugs such as heroin and cocaine. Most of the neonatal manifestations of in utero exposure center on General Newborn Condition 151 neurobehavioral effects (irritability, jitteriness, hypertonicity). There is growing evidence to show that infants exposed to many of these medications develop irritability, jitteriness, and mild respiratory distress, which are usually transient and self-limited. Women who are on psychotropic medications and become pregnant have to be made aware of the potential risk profiles these medications have for their fetus and infant and decide whether they wish to continue their medications throughout pregnancy. However, the risks to the fetus of a mother with a poorly controlled mood or psychiatric disorder can be harmful to the fetus and infant as well. The riskenefit ratio of the use of these medications in pregnancy continues to be studied as their prevalence grows. While many studies are inconclusive, there is growing evidence to suggest there is an increased risk of mild cardiac defects with certain medications (reviewed later in this chapter). Another commonly observed outcome is the self-limiting neonatal behavioral syndrome. Infants are irritable with poor sleeping patterns, prolonged crying, and poor feeding, and, although self-limited, it sometimes requires medication as described in the previous sections. Paroxetine hydrochloride (Paxil) is commonly used to treat depression and anxiety. It readily crosses the placenta, and although it was originally thought that it does not increase teratogenic risk, more recent advisories indicate that infants of women receiving paroxetine in the first trimester had 1. Levels in breast milk are variable with concentrations higher in foremilk as compared with hind milk. Therefore, it appears that for healthy full-term infants, there may be no reason to discourage women on Paxil from breastfeeding.
Purchase benicar mastercard
Although sepsis may be suspected and treated heart attack songs videos benicar 10mg cheap, the signs of low cardiac output should always alert the examining physician to hypertension ppt buy benicar 20 mg without prescription the likely possibility of congenital heart disease arrhythmia with normal ekg buy 10mg benicar with mastercard. A complete physical examination provides important clues to the anatomic diagnosis. Inexperienced examiners frequently focus solely on the presence or absence of cardiac murmurs, but much more additional information should be obtained during a complete examination. Mottling of the skin and/or an ashen, gray color are important clues to severe cardiovascular compromise and incipient shock. While observing the infant, particular attention should be paid to the pattern of respiration including the work of breathing and use of accessory muscles. Before auscultation, palpation of the distal extremities with attention to temperature and capillary refill is imperative. The cool neonate with delayed capillary refill should always be evaluated for the possibility of severe congenital heart disease. While palpating the distal extremities, note the presence and character of the distal pulses. Diminished or absent distal pulses are highly suggestive of obstruction of the aortic arch. Palpation of the precordium may provide an important clue to the presence of congenital heart disease. During auscultation, the examiner should first pay particular attention to the heart rate, noting its regularity and/or variability. The heart sounds, particularly the second heart sound, can be helpful clues to the ultimate diagnosis as well. A split-second heart sound is a particularly important marker of the existence of two semilunar valves, although it is often difficult to be sure of S2 splitting with the rapid heart rate of a neonate. Differentiating an S3 from an S4 heart sound is challenging in a tachycardic newborn; however, a gallop rhythm of either type is unusual and suggests the possibility of a significant left-to-right shunt or myocardial dysfunction. Cardiovascular Disorders 479 the presence and intensity of systolic murmurs can be very helpful in suggesting the type and severity of the underlying anatomic diagnosis; systolic murmurs are usually due to (i) semilunar valve or outflow tract stenosis, (ii) atrioventricular valve regurgitation, or (iii) shunting through a septal defect. For a more complete description of auscultation of the heart, refer to one of the cardiology texts listed at the end of the chapter. A careful search for other anomalies is essential because congenital heart disease is accompanied by at least one extracardiac malformation 25% of the time. Usually, an automated Dinamap is used, but in a small neonate with pulses that are difficult to palpate, manual blood pressure measurement with Doppler amplification may be necessary for an accurate measurement. A systolic pressure that is 10 mm Hg higher in the upper body compared to the lower body is abnormal and suggests coarctation of the aorta, aortic arch hypoplasia, or interrupted aortic arch. It should be noted that a systolic blood pressure gradient is quite specific for an arch abnormality but not sensitive; a systolic blood pressure gradient will not be present in the neonate with an arch abnormality in whom the ductus arteriosus is patent and nonrestrictive. Therefore, the lack of a systolic blood pressure gradient in newborn does not conclusively rule out coarctation or other arch abnormalities, but the presence of a systolic pressure gradient is diagnostic of an aortic arch abnormality. In infants, particularly in newborns, the size of the heart may be difficult to determine due to overlying thymus. In addition to heart size, notation should be made of visceral and cardiac situs (dextrocardia and situs inversus are frequently accompanied by congenital heart disease). The aortic arch side (right or left) can frequently be determined; a right-sided aortic arch is associated with congenital heart disease in 90% of patients. Dark or poorly perfused lung fields suggests decreased pulmonary blood flow, whereas diffusely opaque lung fields may represent increased pulmonary blood flow or significant left atrial hypertension. Longitudinal study of the standard electrocardiogram in the healthy premature infant during the first year of life. Comparative study of the electrocardiograms of healthy fullterm and premature newborns. In all neonates with suspected critical congenital heart disease (not just those who are cyanotic), a hyperoxia test should be considered. This single test is perhaps the most sensitive and specific tool in the initial evaluation of the neonate with suspected recent disease. In sites with timely access to echocardiography, a complete hyperoxia test may not be performed; however, it is important to realize what a valuable test this can be when echocardiography is not easily and quickly available. To investigate the possibility of a fixed, intracardiac right-to-left shunt, the arterial oxygen tension should be measured in room air (if tolerated) followed by repeat measurements with the patient receiving 100% inspired oxygen (the "hyperoxia test"). A markedly higher oxygen content in the upper versus the lower part of the body can be an important diagnostic clue to such lesions, including all forms of critical aortic arch obstruction or left ventricular outflow obstruction. There are also rare cases of "reverse differential cyanosis" with elevated lower body saturation and lower upper body saturation. This occurs only in children with transposition of the great arteries with an abnormal pulmonary artery to aortic shunt due to coarctation, interruption of the aortic arch, or suprasystemic pulmonary vascular resistance ("persistent fetal circulation"). On the basis of the initial evaluation, if an infant has been identified as likely to have congenital heart disease, further medical management must be planned, as well as arrangements made for a definitive anatomic diagnosis. This may involve transport of the neonate to another medical center where a pediatric cardiologist is available. For the neonate who presents with evidence of decreased cardiac output or shock, initial attention is devoted to the basics of advanced life support. A stable airway must be established and maintained as well as adequate ventilation. In the neonate, this can most reliably be accomplished through the umbilical vessels. Volume resuscitation, inotropic support, and correction of metabolic acidosis are required with the goal of improving cardiac output and tissue perfusion (see Chap. The neonate who "fails" a hyperoxia test (or has an equivocal result in addition to other signs or symptoms of congenital heart disease) as well as the neonate who presents in shock within the first 3 weeks of life is highly likely to have congenital heart disease. In infants who will not require transport, intubation may not be required but continuous cardiorespiratory monitoring is essential. In the neonate with ductal-dependant pulmonary blood flow, oxygen saturation will typically improve and the pulmonary blood flow remains secure until an anatomic diagnosis and plans for surgery are made. In neonates with transposition of the great arteries, maintenance of a patent ductus improves intercirculatory mixing. Most important, neonates who present in shock in the first few weeks of life have duct-dependent systemic blood flow until proved otherwise; resuscitation will not be successful unless the ductus is opened. This is usually due to lesions with left atrial hypertension: hypoplastic left heart syndrome with restrictive patent foramen ovale, subdiaphragmatic total anomalous pulmonary venous return, mitral atresia with restrictive patent foramen ovale, transposition of the great arteries with intact ventricular septum with restrictive patent foramen ovale, and some cases of Ebstein anomaly (see V. Continuous infusions of inotropic agents, usually the sympathomimetic amines, can improve myocardial performance as well as perfusion of vital organs and the periphery. Care should be taken to replete intravascular volume before institution of vasoactive agents. Dopamine is a precursor of norepinephrine and stimulates -1, dopaminergic, and -adrenergic receptors in a dose-dependent manner. Dopamine can be expected to increase mean arterial pressure, improve ventricular function, and improve urine output with a low incidence of side effects at doses 10 g/kg/minute. Dobutamine is an analog of dopamine, with predominantly -1 effects and relatively weak -2 and -receptortimulating activity.

Infectious Diseases 631 Guidelines for the Management of Asymptomatic Infants Born at 35 weeks Gestation at Risk for Early-Onset Sepsis No Maternal Fever Maternal Fever 100. Chorioamnionitis is an obstetrical clinical diagnosis made on the basis of clinical findings, laboratory data and fever. If obstetrical staff diagnose chorioamnionitis, the infant should be evaluated for sepsis and receive empiric antibiotic treatment. Maternal fever that occurs within one hour of delivery should be treated like intrapartum fever. Blood cultures should consist of aerobic and anaerobic bottles with minimum 1 cc blood in each bottle. We take into account the impact of a clustering of risk factors for sepsis to guide treatment decisions, as well as the use of intrapartum antibiotic therapy, to guide management decisions. Less common organisms that can cause serious early-onset disease include Listeria monocytogenes and Citrobacter diversus. Risk factors for early-onset group B streptococcal sepsis: estimation of odds ratios by critical literature review. If a woman has a documented history of anaphylactic penicillin or cephalosporin allergy (including urticaria, angioedema, and/or respiratory distress), clindamycin is recommended if the colonizing isolate is fully susceptible to this antibiotic; otherwise vancomycin is the recommended agent. There is ongoing racial disparity with the incidence among black infants roughly four times that of white infants. The total duration of therapy should be at least 10 days for sepsis without a focus, 14 to 21 days for meningitis, and 28 days for osteomyelitis. Bone and joint infections that involve the hip or shoulder require surgical drainage in addition to antibiotic therapy. The K1 antigen has been shown to be a primary factor in the development of meningitis in a rat model of E. The K1 capsule is a poor immunogen, however, and despite widespread carriage of this strain in the population, there is usually little protective maternal antibody available to the infant. When there is a strong clinical suspicion for sepsis in a critically ill infant, the possibility of ampicillin-resistant E. The addition of a third-generation cephalosporin such as cefotaxime or ceftazidime is recommended in this setting. These bacteria do not cause significant disease in immunocompetent adults, but can cause severe illness in the elderly, in immunocompromised patients, in pregnant women and their fetuses, and in newborns. There is human epidemiologic evidence and evidence in animal models of listeriosis that indicate that L. The bacteria readily invades the placenta and can infect the developing fetus by either ascending infection, direct tissue invasion, or hematogenous spread, causing spontaneous abortion or preterm labor and delivery, and often fulminant early-onset disease. The true incidence of listeriosis in pregnancy is difficult to determine because many cases are undiagnosed when they result in spontaneous abortion of the previable fetus. Listeriosis can result from ingestion of contaminated food such as soft cheeses, deli meat, and hot dogs. Epidemic outbreaks of listeriosis affecting both pregnant and nonpregnant adults are reported. An epidemic outbreak Infectious Diseases 637 in Massachusetts in 2008 resulted in three elderly deaths, a premature delivery, and a term stillbirth. This outbreak was notable in that the source of infection was pasteurized milk produced a single dairy, highlighting the potential for postpasteurization contamination of processed foods with Listeria. The organisms can be gram-variable and depending on growth stage, can also appear cocci-like, and can therefore be initially misdiagnosed on a Gram stain. Listeria possess a variety of virulence factors, including surface proteins that promote cellular invasion, and enzymes (listeriolysin O, phospholipase) that enhance the ability of the organism to persist intracellularly. On pathologic examination of tissues infected with Listeria, miliary granulomas and areas of necrosis and suppuration are seen. Both T cell-mediated killing as well as immunoglobulin M (IgM) complement-mediated killing are involved in host response to listeriosis. Deficiencies in both of these arms of the newborn immune system may contribute to the virulence of L. Viridans streptococci (species such as Streptococcus mitis, Streptococcus oralis, and Streptococcus sanguis, which are part of the oral flora), enterococci, and Staphylococcus aureus are next in frequency. Listeria, a variety of gram-negative organisms (Klebsiella, Hemophilus, Enterobacter, and Pseudomonas species) and the anaerobe B. Gram-negative organisms, especially Hemophilus influenzae and Klebsiella, predominate in some Asian and South American countries. Causes of bacteremia in older infants (such as Streptococcus pneumoniae, and Neisseria meningitidis) occur less frequently. Mortality is low if promptly treated, and sequelae are few unless meningitis occurs. The mortality among infants with gram-negative infections was about 40%, and 30% with fungal infections. Epidemiologic, clinical, and microbiologic characteristics of late-onset sepsis among very low birth weight infants in Israel: a national survey. They are believed to cause bacteremia by first colonizing the surfaces of central catheters. Disease is frequently complicated by focal site infections (soft tissue, bone, and joint infections are commonly observed in neonates) and marked by persistent bacteremia despite antibiotic administration. Joint infections often require open surgical drainage and can lead to joint destruction and permanent disability. Community-acquired isolates are usually resistant only to -lactam antibiotics and erythromycin. Infection control measures, including identification of colonized infants by routine surveillance and cohorting and isolation of colonized infants, may be required to prevent spread and persistence of the organism. Enterococci are resistant to cephalosporins and often resistant to penicillin G and ampicillin; treatment requires the synergistic effect of an aminoglycoside with ampicillin or vancomycin. Linezolid is approved for use in neonates and is effective against vancomycin-resistant E. Treatment decisions should be made in consultation with infectious diseases experts. Treatment requires a combination of two agents active against Pseudomonas, such as ceftazidime, piperacillin/tazobactam, gentamicin, or tobramycin. Enterobacter sakazakii has received publicity due to outbreaks of disease caused by contamination of powdered infant formulas with this organism. Enterobacter species contain chromosomally encoded, inducible -lactamases (AmpC-encoded cephalosporinases), and treatment with third-generation cephalosporins, even if the initial isolate appears to be sensitive, can result in the emergence of cephalosporin-resistant organisms. In addition, stably derepressed, high-level, constitutive, AmpC-producing strains of Enterobacter, Citrobacter and Serratia have been reported. The fourthgeneration cephalosporin cefepime is relatively stable against AmpC-type -lactamases.

However, ethical, legal, religious and social issues of these procedures need clarification and understanding. Many, however, prefer to have their own genetic babies and resort to adoption when all other measures fail. Oocyte collection-antibiotics and progesterone given 2 days prior to oocyte collection to prevent infection and for better implantation. Cryopreservation avoids repeat aspirations, reduces the cost of the procedure and can be used in subsequent cycles as well as for further pregnancies. Cryopreservation is also useful in young men who have to undergo surgery, radiotherapy or chemotherapy for cancer, or are frequent travellers. Most gynaecologists prefer to transfer two embryos in each cycle, and some continue with more. Donor eggs are offered to women with poor egg numbers or quality and elderly women. A 28-year-old woman presents with irregular menstrual cycles and primary infertility. A 23-year-old woman presents with primary sterility, hirsutism and oligomenorrhoea. A 32-year-old woman presents with secondary infertility, regular cycles, last delivery was 6 years ago. Andrology has expanded into extensive male investigations, study of the morphology and functions of the sperm. Although several factors are responsible for female infertility, the most common causes are tubal blockage, ovarian dysfunction and anovulation. Ovulation is now monitored by ultrasound scan, and hormone profile study is reserved in abnormal findings and when a woman is given pituitary hormones for induction of ovulation. Ovulation induction, tubal microsurgery, balloon tuboplasty and hysteroscopic cannulation are the added armamentarium in the treatment of female infertility, which are yielding better results. Cryopreservation of sperms, ova and embryos is one big step forward in the field of infertility. It avoids repeated aspirations and other procedures, and thereby reduces the costs. It also permits donation of eggs as well as of sperms to couples whose husband is azoospermic or wife is incapable of ovulation. Recent Advances in Obstetrics and Gynaecology 21 Ovarian hyperstimulation syndrome. In: Best Practice and Research: Clinical Obstetrics and Gynaecology, Vol 20(5): 75178, Elsevier,2006.

In: Progress in Obstetrics and Gynecology, 1st Edition, Vol 18: 375, Churchill Livingstone: Elsevier, 2008. The need of birth control at a personal level has arisen through increased cost of living, scarcity of accommodation, a desire for better education of children in the present competitive world, and an overall desire for an improved standard of living. The socio-economic problems of overpopulation are too well known to be discussed here. Reproductive health and medical grounds are now the other considerations for birth control. It is reckoned that a woman below 20 years is not physically grown to produce a child. Spacing birth, 3 years apart, is considered beneficial for both the mother and the child. A multiparous woman from a low-income group generally suffers from malnutrition and is also predisposed to prolapse, stress incontinence, chronic cervicitis and cancer of the cervix. The spacing of childbirth and limiting the number of pregnancies are strongly desirable for this reason. The previous two caesarean sections is indication of a repeat caesarean section in a subsequent pregnancy which exposes the woman to further surgical risks. In India, it is customary to suggest sterilization operation at the time of the third caesarean section, and sometimes during the second caesarean section. Other indications for sterilization include the mentally retarded woman and the one suffering from serious psychiatric disorders like schizophrenia. A woman who has given birth to a child with a genetic disorder needs genetic counselling and may be advised against future pregnancy. This contraception may be temporary when the effect of preventing pregnancy lasts while the couple uses the method but the fertility returns immediately or within a few months of its discontinuation. The permanent contraceptive methods are surgical: tubectomy in a woman and vasectomy in a man. Unfortunately, no contraception has proved perfect and its effectiveness, safety and techniques vary. This therefore requires counselling, screening of the couple and offering the best method suited to the couple. The choice of contraception depends upon the following: n n n n Availability, cost. The couple may need to change one contraception to another from time to time during the reproductive period. Personal, medical and social factors should be taken into consideration during counselling. Failure rate of any contraceptive method is described in terms of pregnancy rate per 100 woman years (Pearl index). Ideal contraceptive methods should be effective, long acting, safe, coital-independent and reversible. In a 28-day cycle, ovulation normally occurs on the 14th day of the cycle, but may occur anytime between the 12th and 16th day. Chapter 20 Birth Control and Medical Termination of Pregnancy the female genital tract may survive for 24 h. The ovum itself may live for 124 h so that intercourse between the 11th and 17th day may result in a pregnancy. The safe period is, therefore, calculated from the first day of the menstrual period until the 10th day of the cycle and from the 18th to the 28th day. An alternative method is to calculate the risk period, which is from 3 days before ovulation to 3 days after ovulation.
Order benicar with a visa
Sinusitis blood pressure medication how long to take effect buy benicar 10mg on line, endocarditis arrhythmia management plano order cheap benicar line, intra-abdominal abscesses (perinephric heart attack anlam buy generic benicar 20 mg on-line, intrahepatic, subdiaphragmatic), and central nervous system lesions (tuberculoma, cysticercosis, abscess, toxoplasmosis) may be relatively asymptomatic. Fever eventually resolves in many of these cases, usually without sequelae, although some may develop definable signs of rheumatic disease over time. Factitious fever or fever produced or feigned intentionally by the patient (Munchausen syndrome) or the parent of a child (Munchausen syndrome by proxy) is an important consideration, particularly if family members are familiar with health care practices (see Chapter 22). Fever should be recorded in the hospital by a reliable individual who remains with the patient when the temperature is taken. Continuous observation over a long period and repetitive evaluation are essential. Consultation with infectious disease, immunology, rheumatic disease, or oncology specialists should be considered. Further tests may include lumbar puncture for cerebrospinal fluid analysis and culture; computed tomography or magnetic resonance imaging of the chest, abdomen, and head; radionuclide scans; and bone marrow biopsy for cytology and culture. Rash distribution and appearance provide important clues to the differential diagnosis, including other infectious agents (Table 97-1). Measles virus infects the upper respiratory tract and regional lymph nodes and is spread systemically during a brief, low-titer primary viremia. A secondary viremia occurs within 5 to 7 days as virus-infected monocytes spread the virus to the respiratory tract, skin, and other organs. Virus is present in respiratory secretions, blood, and the urine of infected individuals. Measles virus is transmitted by droplets or the airborne route and is highly contagious. Infected persons are contagious from 1 to 2 days before onset of symptoms-from about 5 days before to 4 days after the appearance of rash-and immunocompromised persons can have prolonged excretion of contagious virus. Epidemiology Measles remains endemic in regions of the world where measles vaccination is not available and is responsible for about 1 million deaths annually. Since 2000 there typically have been fewer than 100 cases reported annually in the United States, although outbreaks resulting from imported virus after international travel occur. Infections of nonimmigrant children during outbreaks may occur among those too young to be vaccinated or in communities with low immunization rates. Most young infants are protected by transplacental maternal antibody until the end of their first year. Clinical Manifestations Measles infection is divided into four phases: incubation, prodromal (catarrhal), exanthematous (rash), and recovery. The incubation period is 8 to 12 days from exposure to symptom onset and a mean of 14 days (range, 7 to 21) from exposure to rash onset. The conjunctiva may reveal a characteristic transverse line of inflammation along the eyelid margin (Stimson line). The macular rash begins on the head (often above the hairline) and spreads over most of the body in a cephalad to caudal pattern over 24 hours. The rash fades in the same pattern, and illness severity is related to the extent of the rash. Cervical lymphadenitis, splenomegaly, and mesenteric lymphadenopathy with abdominal pain may be noted with the rash. The term modified measles describes mild cases of measles occurring in persons with partial protection against measles. Modified measles occurs in persons vaccinated before 12 months of age or with coadministration of immune serum globulin, in infants with disease modified by transplacental antibody, or in persons receiving immunoglobulin. In patients with acute encephalitis, the cerebrospinal fluid reveals an increased protein, a lymphocytic pleocytosis, and normal glucose levels. Serologic testing for IgM antibodies that appear within 1 to 2 days of the rash and persist for 1 to 2 months in unimmunized persons confirms the clinical diagnosis, though IgM antibodies may be present only transiently in immunized people. Suspected cases should be reported immediately to the local or state health department. Koplik spots are pathognomonic but are not always present at the time the rash is most pronounced. The rash must be differentiated from rubella, roseola, enteroviral or adenoviral infection, infectious mononucleosis, toxoplasmosis, meningococcemia, scarlet fever, rickettsial disease, Kawasaki disease, serum sickness, and drug rash. Treatment Routine supportive care includes maintaining adequate hydration and antipyretics. High-dose vitamin A supplementation has been shown to improve the outcome of infants with measles in developing countries. The World Health Organization recommends routine administration of vitamin A for 2 days to all children with acute measles. Chapter 97 u Infections Characterized by Fever and Rash 331 Complications and Prognosis Otitis media is the most common complication of measles infection. Interstitial (measles) pneumonia can occur, or pneumonia may result from secondary bacterial infection with Streptococcus pneumoniae, Staphylococcus aureus, or group A streptococcus. Persons with impaired cell-mediated immunity may develop giant cell (Hecht) pneumonia, which is usually fatal. Encephalomyelitis occurs in 1 to 2 per 1000 cases and usually occurs 2 to 5 days after the onset of the rash. Early encephalitis probably is caused by direct viral infection of brain tissue, whereas later onset encephalitis is a demyelinating and probably an immunopathologic phenomenon. Subacute sclerosing panencephalitis is a late neurologic complication of slow measles infection that is characterized by progressive behavioral and intellectual deterioration and eventual death. It occurs in approximately 1 in every 1 million cases of measles, an average of 8 to 10 years after measles. Late deaths in adolescents and adults usually result from subacute sclerosing panencephalitis. Other forms of measles encephalitis in immunocompetent persons are associated with a mortality rate of approximately 15%, with 20% to 30% of survivors having serious neurologic sequelae. Rubella virus invades the respiratory epithelium and disseminates via a primary viremia. After replication in the reticuloendothelial system, a secondary viremia ensues, and the virus can be isolated from peripheral blood monocytes, cerebrospinal fluid, and urine. Rubella virus is most contagious through direct or droplet contact with nasopharyngeal secretions from 2 days before until 5 to 7 days after rash onset, although virus may be present in nasopharyngeal secretions from 7 days before until 14 days after the rash. Maternal infection during the first trimester results in fetal infection with generalized vasculitis in more than 90% of cases. Infants with congenital rubella may shed the virus in nasopharyngeal secretions and urine for longer than 12 months after birth and may transmit the virus to susceptible contacts. Epidemiology In unvaccinated populations, rubella usually occurs in the spring, with epidemics occurring in cycles of every 6 to 9 years. Outbreaks of rubella occasionally occur in nonvaccinated groups from internationally imported cases. Contraindications to measles vaccine include immunocompromised states or an immunosuppressive course of corticosteroids (>2 mg/kg/day for >14 days); pregnancy; or recent administration of immunoglobulin (3 to 11 months, depending on dose). Susceptible household contacts with a chronic disease or who are immunocompromised should receive postexposure prophylaxis with measles vaccine within 72 hours of measles exposure or immunoglobulin within 6 days of exposure.
