High index of suspicion is required for early diagnosis as the radiographs may be negative in the first 2 weeks. Treatment · Initial suspicion of fracture with negative X-rays: treat as though scaphoid fracture is present: Place the child in short thumb spica splint for 12 weeks and then X-rays repeated after 2 weeks. The radiographs (a, b) show a lateral condyle fracture (arrow) Scaphoid Fracture Background · Most common carpal fracture in pediatric patients. Fractures can result in disruption of the blood supply to the bone resulting in avascular necrosis and collapse of the bone. Post reduction radiographs (b, c) showed incongruence lateral view of the elbow (compare with the normal side (d)). Surgery was done for removal of the piece from the joint and internal fixation by screws (e) 531 Tibial Shaft Fracture Diagnosis · Pain, swelling, and deformity of the affected extremity · Can be complicated by compartment syndrome (pain increases after application of cast) · Radiograph will show the fracture. Most cases can be treated by closed reduction and casting, some cases will require internal fixation. Oblique radiograph shows fracture of the scaphoid Toddler Fracture Background · A spiral tibial shaft fracture that occurs in toddler due to twisting trauma. In some cases, the fracture does not show up in the primary radiograph, but the follow-up 532 A. A 14-year-old boy fell down while running down the stairs and had left leg pain and swelling. This fracture was managed nonsurgically with casting radiograph will show the evidence of healing (periosteal new bone formation and callus at the fracture site). Ankle Fracture Background · the mechanism of the fracture is twisting injury to the ankles. Diagnosis · Pain, swelling, and deformity of the affected ankle · Inability to bear weight on the affected side. On exam, there was tenderness of the lower leg with pain on external rotation of the tibia. Radiograph shows spiral fracture of the spiral non displace lower end of the tibia Treatment · Orthopedic referral. Displaced fracture or fracture with widening of the distance between fibula and tibia will require surgical fixation. Treatment · Orthopedic referral: Stable injuries can be treated with weight bearing as tolerated in hard sole shoes. A cortical piece of bone can be seen in the middle lesion (fallen leaf) sign is pathognomonic of a simple bone cyst. Treatment · Orthopedic referral: chemotherapy, radiotherapy, and surgical excision of the tumor. Notice the simple bone cyst that affected the proximal humerus (white arrows) Treatment · Orthopedic referral for symptomatic lesion. A thin subperiosteal shell of new bone surrounds the structure and contains cystic blood-filled cavities. Diagnosis · Pain and swelling over the affected bone · Pathologic fracture · Radiographs: soap-bubble appearance with an eggshell appearing bony rim surrounding the lesion Treatment · Orthopedic referral: the lesion can be treated with intralesional curettage and bone grafting or wide excision of the lesion. Osteoid Osteoma Background · Osteoid osteoma is a benign tumor consisting of a welldemarcated bone-forming lesion called a nidus, surrounded by a radio-dense, reactive zone of host bone. In most cases, the defect cannot be seen, and surrounding sclerosis is the only finding in the radiograph. Orthopedics Disorders and Sport Injuries 535 Diagnosis · Osteochondromas are commonly diagnosed incidentally based on a radiograph obtained for other reason. Osteosarcoma Background · Osteosarcoma is a primary malignant tumor of bone with malignant osteoid formation arising from bone-forming mesenchymal cells. Diagnosis · Pain is the first and most common symptom, constant, severe · Swelling · Pathological fracture (rare) · X-rays: skeletally immature patient with an osteolytic lesion which is metaphyseal, eccentric, and having illdefined edges with reactive bone formation and erosion of the cortex.

Torticollis Background · It is the clinical finding of tilting the head to one side in combination with rotation of face to the opposite side. Scoliosis Background · Lateral curvature of the spine associated with a rotational element. The idiopathic scoliosis is further classified according to the age of onset into: infantile (the scoliosis starts in the first 2 years of life), juvenile (the scoliosis starts between 3 and 9 years old), adolescent (the scoliosis starts at or after the age of 10 years) which is the most common type. The typical curve is right thoracic (means that the convexity is toward the right) · Risser stage: indicates the stage of skeletal maturity. It depends on the ossification of the iliac apophysis which proceeds from lateral to medial. Treatment · Indication for referral to orthopedic surgeon: curves more than 20° or more than 7° rotation by scoliometer. Scheuermann Kyphosis Background · Juvenile developmental disease with increased thoracic or thoraco-lumbar kyphosis due to structural deformity of the spine with increased anterior wedging of the vertebrae.

Purchase atarax with mastercard
Lymphadenopathy anxiety symptoms belching buy discount atarax online, malaise and generalised lesions are relatively uncommon and the immune response is poor (Leavell et al anxiety 9 year old daughter purchase generic atarax online. Clinical Features the progressive stages of human infection have been described in detail (Leavell et al anxiety chest pain generic 10 mg atarax mastercard. This, seen 12 weeks after infection, has a red centre surrounded by a white halo and an outer inflamed halo. In some patients this may enlarge and persist for some weeks before resolving (Figure 15. Occasionally very large granulomatous lesions occur which may need surgical removal (Pether et al. Systemic reaction is relatively uncommon and the lesion is often not particularly painful. Attention has been drawn to erythema multiforme as a common complication of orf but, because most ordinary cases go unreported, the actual incidence of erythema is probably low. The immune response in natural human infection has been investigated (Yirrel et al. Bristol Medico-Chirurgical Journal, 97, 12; reproduced by permission of the Editor. This is consistent with the occurrence of second attacks in 812% of individuals (Robinson and Peterson, 1983; Yirrell and Vestey, 1994). Clinical diagnosis of uncomplicated cases in patients with a known animal contact should not cause difficulties. Consequently, a disproportionately large number of reported cases have no known contact with infected animals. Of approximately 500 cases surveyed during 19781995, some 45% had no such contact. Clinical diagnosis of such cases, particularly if severe or prolonged, may cause difficulties. In particular, large weeping granulomatous or papillomatous lesions may be misdiagnosed as malignancies, resulting in one case in unnecessary amputation (Johanneson et al. Individuals should take care not to spread infection by autoinoculation or to contacts, including animals. The vaccine used to control orf in sheep is fully virulent and has caused human infection. It has been the subject of a comprehensive recent review (Birthistle and Carrington, 1997). Some nucleic acid detection techniques are published (Torfason and Gunadottir, 2002). After a variable, sometimes lengthy, incubation period, papules develop, formed by epidermal hypertrophy. This produces a nodule and also extends the dermis downwards, but the basement membrane usually remains intact. Characteristic inclusions (Henderson Paterson bodies) are formed in the prickle cell layer and gradually enlarge as the cells age and migrate to the surface. The inclusion is a well-defined sac packed with virions (Shelly and Burmeister, 1986). The lesion is circumscribed by a connective tissue capsule and the dermis, apart from distortion, remains essentially normal. Epidemiology Human infection is an occupational hazard of farmworkers, abattoir workers, veterinary surgeons and students and others with frequent exposure to sheep, cattle or goats. It is most common in the lambing and calving seasons, and more commonly reported in sheep workers than cattle workers; this probably reflects differences in animal husbandry. Of 191 cases with a known source surveyed during 19781995, 84% had an ovine source and 16% were from cattle. During the same period 32 cases occurred in abattoir workers (Baxby and Bennett, 1997a). The characteristic lesion begins as a small papule and, when mature, is a discrete, waxy, smooth, dome-shaped pearly or fleshcoloured nodule, often umbilicated (Figure 15. They may become confluent along the line of a scratch and satellite lesions are occasionally seen. In adults they tend to occur on Control Most workers at risk get infected at some stage and reinfection is not uncommon. Control Infection is benign and recovery usually spontaneous, but treatment may be sought for cosmetic reasons, particularly for facial or multiple lesions. Chemical treatments include phenolics, silver nitrate, trichloroacetic and glacial acetic acid. Mild trauma may induce a cure, which may be due to release of virus-infected cells accessible to the immune system. Prevention in developed countries is based on attention to personal hygiene, and in developing countries to this and to general improvements in living conditions. Although relatively unimportant per se, the possibility that molluscum may act as a marker for more serious conditions has been raised (Oriel, 1987). From a transparency kindly supplied by Dr J Verbov the trunk, pubic area and thighs, but in all cases infection may be transmitted to other parts by autoinoculation (Brown et al. Individual lesions last for about 2 months but the disease usually lasts 69 months (Steffen and Markman, 1989). An account of 264 laboratory-confirmed cases from Zaire (Democratic Republic of Congo), with colour illustrations, is available (Jezek et al. Recent anecdotal reports of human disease outside Africa have been published and illustrate the need to consider poxvirus aetiologies of illness in travellers returning from and emigrants from endemic areas (Croitoru et al. Diagnosis the appearance of lesions in normal cases is generally sufficiently characteristic to permit clinical diagnosis. Virions can usually be seen in large numbers if material expressed from the lesion is examined by electron microscopy. The virus occurs worldwide and tends to be more common in socially deprived areas. The lesion is characterised by pronounced epidermal hyperplasia with little involvement of the dermis. The lesion starts as a macule and progresses to a raised nodule, which becomes umbilicated (Figure 15. Diagnosis For diagnosis of tanapox the limited geographical distribution should be considered, as well as travel history. The solid nodular/ulcerated lesions are larger and develop more slowly than those of monkeypox, but are smaller and develop more rapidly than those of tropical ulcers. Virus can be detected by electron microscopy but this would not exclude morphologically similar viruses; nucleic acid tests (Stich et al.

In addition anxiety symptoms ear ringing order genuine atarax online, in the case of chickenpox anxiety or depression generic atarax 10mg on-line, prodromal fever and systemic manifestations are mild anxiety symptoms centre buy generic atarax 25mg online, if manifest at all; the lesions are superficial in nature; and lesions in different developmental stages may present in the same area of the body. Other diseases confused with vesicular-stage smallpox included monkeypox, generalised vaccinia, disseminated herpes zoster, disseminated herpes simplex virus infection, drug reactions (eruptions), erythema multiforme, enteroviral infections, scabies, insect bites, impetigo and molluscum contagiosum. Diseases confused with haemorrhagic smallpox included acute leukaemia, meningococcaemia and idiopathic thrombocytopenic purpura. Associated constitutional symptoms included backache, headache, vomiting and prostration. Within 12 days after incubation, a systemic rash appeared that was characteristically centrifugally distributed. Initially, each rash lesion appeared macular, then papular, enlarging and progressing to a vesicle by day 45 and to a pustule by day 7; the lesions were encrusted and scabby by day 14 and sloughed off. Skin lesions were deep-seated and in the same stage of development in any one area of the body. Less severe manifestations (modified smallpox or variola sine eruptione) occurred in some vaccinated individuals, whereas haemorrhagic or flatpox types of smallpox are thought to have developed as a result of impaired immune response of patients. A discrete type of the ordinary form, with typical febrile prodrome and rash, resulted from alastrim variola minor infection (Fenner et al. Ordinary smallpox was subgrouped into three categories, based on the extent of rash on the face and the body. In ordinary confluent smallpox, no area of skin was visible between the vesiculo-pustular rash lesions on the trunk or the face. Patches of normal skin were visible between rash lesions on the trunk in ordinary-semi-confluent disease, as well as on the face in ordinary discrete disease. Prior to its eradication, smallpox as a clinical entity was relatively easy to recognise, but other exanthematous illnesses were mistaken for this disease (Fenner et al. Initial surveys in Zaire (now Democratic Republic of Congo) detected monkeypox-specific antibodies in 85/347 (25%) squirrels sampled but from none of 233 terrestrial rodents. Monkeypox-specific antibody has been detected in very few monkeys, which, like humans are probably only occasional hosts (Khodakevich et al. Particular attention was focused on monkeypox from 1970, when smallpox surveillance activities in Africa revealed cases of human monkeypox, clinically indistinguishable from smallpox, particularly in Zaire. During the incubation period virus is distributed initially to internal organs and then to the skin (Fenner et al. The main differences are a greater degree of lymphadenopathy and a lower capacity for case-to-case spread. Clinical Features In general the clinical features of disease as seen in Central Africa are those of a classical or modified case of smallpox. The most obvious difference is the pronounced lymphadenopathy, which involves the submandibular, cervical and sublingual regions (Figure 15. In Zaire during 19811986, 291 cases (86%) occurred in children <10 years old and only 12 (4%) of these had vaccination scars. Complications occurred in about 40% of patients: the most common were bacterial skin infections (16%) and respiratory (12%) and gastrointestinal (5%) disorders. The overall mortality was approximately 10%; however, all the deaths occurred in unvaccinated children, in which group mortality is around 15% (Jezek and Fenner, 1988; Jezek et al. Clinical diagnosis may present a problem because fewer physicians now have experience with smallpox, which human monkeypox closely resembles. Access to a virus diagnostic laboratory should permit detection of virus by electron microscopy and molecular methods, and this provides a sensitive presumptive diagnosis. In some circumstances it may be important to distinguish between monkeypox and tanapox (see below). In the past it was essential to differentiate between monkeypox and Pathogenesis the pathogenesis of human monkeypox is essentially the same as that of smallpox, i. Comparison of the genomes of smallpox virus and monkeypox virus strains isolated up to 1986 suggested that they have evolved separately (Douglas and Dumbell, 1992) and the results of complete genome analysis (Shchelkunov et al. Laboratory workers studying monkeypox virus should be vaccinated with vaccinia and handle the virus in safety cabinets. Currently, an array of molecular diagnostic techniques permits the speciation of these viruses (Ibrahim, 2003; Meyer et al. The close serological relationships among orthopoxviruses makes detection of monkeypox-specific antigens difficult but methods are available and being refined which may be of value, particularly for epidemiological studies of monkeypox virus in its natural reservoirs (Khodacevich et al. Of human cases in the 19811986 Zaire survey, 74% were confirmed by detection of virus by electron microscopy and virus isolation, and in another 22% retrospectively by serology. These ranged from rare but severe complications, such as generalised vaccinia, which occurred in about 200/million primary vaccinees, to relatively mild but still troublesome satellite lesions or nondescript rashes, which occurred in about 8% of vaccinees (Baxby, 1993; Fulginetti et al. Routine use of smallpox vaccine is now discontinued; however, to enhance response preparedness to the potential malevolent reintroduction of smallpox, a number of public health personnel have recently been vaccinated. Policies for vaccine use in laboratory personnel working with orthopoxviruses varies internationally. It is necessary for those working with monkeypox virus, but policies about its use for those working with cowpox virus and vaccinia virus vary (Baxby, 1993). Epidemiology and Control Management of individual cases is supportive, with case-to-case spread reduced by isolation and, if available, the use of smallpox vaccine for contacts. Human cases in Africa occur in villages in the rainforests where a variety of animals are captured for food. The results of the comprehensive surveys carried out in the 1980s indicated that those infected were principally unvaccinated children and that case-to-case spread was unusual. Control measures are based in interposing a buffer zone of cleared land between the arboreal reservoir and cultivated land, the development of animal husbandry as a source of meat, and on education in the handling of wildlife, with emphasis on any trapping done by those previously vaccinated; continued vaccination was not thought necessary (Khodakevich et al. Only occasional human cases were reported from Central Africa following cessation of routine surveillance activities post-smallpox eradication, but there was a resurgence in 19961997 which has not yet been fully explained. Increased political unrest would lead to population displacement and breakdown of routine control measures, and the levels of vaccine-induced immunity will decline with time. However, studies on isolates obtained after the cessation of routine vaccination suggest that cases continue to be caused by a virus different from vaccinia (Dumbell and Richardson, 1993). However, at present it is not known whether buffaloes are the reservoir host or whether wildlife reservoirs are involved, as in the case of cowpox (see below). The virus is maintained in a variety of European rodents, and the most commonly reported victim is the domestic cat, from which source human infections are acquired (Baxby and Bennett, 1997b). The resultant recombinant strains retain their infectivity and, in general, the inserted genes are expressed properly. Human infection with such vectored vaccines has been rarely reported (Rupprecht, 2001). Such concerns have led to the development of severely attenuated vaccinia vectors (Staib and Sutter, 2003; Smith et al. Other poxviruses are being considered as vaccine vectors, in particular, the use of avian poxviruses as vectors for mammalian vaccines. These are of interest because avian poxviruses induce a good immune response to the foreign gene product without initiating productive infection in mammals (Limbach and Paoletti, 1996).

Mutation analysis may confirm the diagnosis in a family and enable predictive genetic testing of relatives anxiety 8 months pregnant purchase atarax 25 mg free shipping, but screening for neoplastic disease in those at risk is difficult anxiety symptoms chills best order atarax. Brain tumour prostate and lung cancer breast cancer breast cancer and soft tissue sarcoma brain tumour leukaemia Figure 11 anxiety 5 things images order 10mg atarax free shipping. Many affected people have involvement of more than one gland but the type of tumour and age at which these develop is very variable within families. First-degree relatives in affected families should be offered predictive genetic testing. Those carrying the mutation require clinical, biochemical and radiological screening to detect presymptomatic tumours. Mutation analysis again provides confirmation of the diagnosis in the index case and presymptomatic tests for relatives. Screening tests in gene carriers include calcium or pentagastrin provocation tests that detect abnormal calcitonin secretion and permit curative thyroidectomy before the tumour cells extend beyond the thyroid capsule. The syndrome follows autosomal dominant inheritance, and clinical, biochemical and radiological screening is recommended for affected family members and those at risk, to permit early treatment of problems as they arise. Other features are macrocephaly, tall stature, palmar pits, calcification of the falx cerebri, ovarian fibromas, medulloblastomas and other tumours. The skin tumours may be extremely numerous and are usually bilateral and symmetrical, appearing over the face, neck, trunk, and arms during childhood or adolescence. Malignant change is very common after the second decade, and removal of the tumours is therefore indicated. Abnormal sensitivity to therapeutic doses of ionising radiation results in the development of multiple basal cell carcinomas in any irradiated area. Hamartomas of the brain, heart, kidney, retina and skin may also occur, and their presence indicates the carrier state in otherwise healthy family members. Childhood tumours Retinoblastoma Sixty percent of retinoblastomas are sporadic and unilateral, with 40% being hereditary and usually bilateral. Hereditary retinoblastomas follow an autosomal dominant pattern of inheritance with incomplete penetrance. About 8090% of children inheriting the abnormal gene will develop retinoblastomas. In bilateral tumours the first mutation is inherited and the second is a somatic event with a likelihood of occurrence of almost 100% in retinal cells. The retinoblastoma gene is therefore acting recessively as a tumour suppressor gene. Tumours may occasionally regress spontaneously leaving retinal scars, and parents of an affected child should be examined carefully. In addition to tumours of the head and neck caused by local irradiation treatment, other associated malignancies include sarcomas (particularly of the femur), breast cancers, pinealomas and bladder carcinomas. A deletion on chromosome 13 found in a group of affected children, some of whom had additional congenital abnormalities, enabled localisation of the retinoblastoma gene to chromosome 13q14. The esterase D locus is closely linked to the retinoblastoma locus and was used initially as a marker to identify gene carriers in affected families. Identification of an interstitial deletion of chromosome 11 in such cases localised a susceptibility gene to chromosome 11p13. Children with hemihypertrophy are at increased risk of developing Wilms tumours and a recommendation has been made that they should be screened using ultrasound scans and abdominal palpation during childhood. These genes are not implicated in familial Wilms tumour, which follows autosomal dominant inheritance with reduced penetrance, and there is evidence for localisation of a familial predisposition gene at chromosome 17q. Many common disorders, however, have an appreciable genetic contribution but do not follow simple patterns of inheritance within a family. The terms multifactorial or polygenic inheritance have been used to describe the aetiology of these disorders. The positional cloning of multifactorial disease genes presents a major challenge in human genetics. Infections Congenital heart disease Diabetes Schizophrenia Coronary Single gene Neural Trauma, Teratogenic tube defects heart disease disorders poisoning defects Figure 12. The liability of a population to a particular disease follows a normal distribution curve, most people showing only moderate susceptibility and remaining unaffected. Relatives of an affected person will show a shift in liability, with a greater proportion of them being beyond the threshold. Genetic susceptibility to common disorders is likely to be due to sequence variation in a number of genes, each of which has a small effect, unlike the pathogenic mutations seen in mendelian disorders. These variations will also be seen in the general population and it is only in combination with other genetic variations that disease susceptibility becomes manifest. Unravelling the molecular genetics of the complex multifactorial diseases is much more difficult than for single gene disorders. Nevertheless, this is an important task as these diseases account for the great majority of morbidity and mortality in developed countries. Approaches to multifactorial disorders include the identification of disease associations in the general population, linkage analysis in affected families, and the study of animal models. Identification of genes causing the familial cases of diseases that are usually sporadic, such as Alzheimer disease and motor neurone disease, may give insights into the pathogenesis of the more common sporadic forms of the disease. In the future, understanding genetic susceptibility may enable screening for, and prevention of, common diseases as well as identifying people likely to respond to particular drug regimes. Several common disorders thought to follow polygenic inheritance (such as diabetes, hypertension, congenital heart disease and Hirschsprung disease) have been found in some individuals and families to be due to single gene defects. In Hirschprung disease (aganglionic megacolon) family data on recurrence risks support the concept of sex-modified polygenic inheritance, although autosomal dominant inheritance with reduced penetrance has been suggested in some families with several affected members. This allows empirical values for risk of recurrence to be calculated, which can be used in genetic counselling. Second degree relatives have a slight increase in risk only and third degree relatives usually have the same risk as the general population. The severity of the disorder and the number of affected individuals in the family also affect recurrence risk. The recurrence risk for bilateral cleft lip and palate is higher than the recurrence risk for cleft lip alone, and the recurrence risk for neural tube defect is 4% after one affected child, but 12% after two. In these disorders the risk of recurrence is higher if the disorder has affected the less frequently affected sex. As with the other examples, the greater genetic susceptibility in the index case confers a higher risk to relatives. A rational approach to preventing multifactorial disease is to modify known environmental triggers in genetically susceptible subjects. Folic acid supplementation in pregnancies at increased risk of neural tube defects and modifying diet and smoking habits in coronary heart disease are examples of effective intervention, but this approach is not currently possible for many disorders.

Cluster B personality disorders include antisocial, borderline, histrionic, and narcissistic types. Patients with antisocial personality disorder show a disregard for and often violate the rights of others. Cluster C personality disorders are characterized by anxiety and include avoidant, obsessive-compulsive, and dependent personality types. Individuals with avoidant personality disorder are sensitive to rejection, are socially inhibited, and have overwhelming feelings of inadequacy. Patients with schizoid personality disorder exhibit voluntary social withdrawal (unlike avoidant patients) and have limited emotional expressions. The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, specifies the active phase of the disease and requires that at least two of the following symptoms be present during a one-month period: delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior, and negative symptoms (eg, flat affect, lack of motivation, or poverty of speech). Moreover, signs of the disturbance must be present for at least six months, such as one of the above symptoms in an attenuated form (eg, magical thinking, social withdrawal, or other negative symptoms). Schizophreniform disorder is similar to schizophrenia except that its symptoms have lasted between one and six months. In contrast, patients with schizophrenia must have had symptoms for longer than six months. This choice incorrectly uses odds rather than incidence rates and also describes the relationship of the findings of the study in reverse. A casecontrol study evaluates the presence of risk factors in people with and without a disease. Although this is the opposite of a cohort study, the results are still reported in terms of disease presence with respect to risk factors; that is, the presence or absence of disease is categorized in the group with risk factors and compared to the group without risk factors. Odds are calculated by dividing those with disease by those without (50 to 50, or 1 to 1). The delusions are not attributable to another psychiatric disorder such as schizophrenia.

False-negatives are those with the cancer who tested negative with the new test (n = 40); thus, 60 / (60 + 40) = 60%. Screening tests theoretically would aim to identify all those with the disease, and therefore high sensitivities are desired. In this case 60% represents a low number, and the ca-1panc blood test would not be a good screening test for the cancer. It is important to correctly detect those without the disease in order to prevent them from undergoing unnecessary treatment or studies that could be painful or harmful to the patient. One of its mechanisms of action consists of increased production and secretion of gastric mucous barrier. Misoprostol, however, is contraindicated in women of childbearing potential due to its abortifacient properties. It can also be used for medical termination of pregnancy of <49 days (in conjunction with mifepristone) and off-label for ripening and labor induction. The chance of neural tube defects is increased in women who do not take prenatal folate supplements. Placenta previa results from abnormal placental implantation where placenta covers the cervical os. Some of the risk factors for this phenomenon are prior cesarean section, multiparity, advanced maternal age, multiple gestations, and prior placenta previa. The syndrome resulting from the presence of an accessory tract is Wolff-Parkinson-White. Hypertrophic cardiomyopathy indeed may lead to ventricular fibrillation and sudden death, but a more common presentation would be a previously healthy adolescent who suddenly collapses under extreme exertion (eg, during a sports game). The primary pathophysiology is a neoplastic proliferation of mature plasma cells producing abnormal immunoglobulins, most commonly IgG. Characteristic features of multiple myeloma include destructive "punched-out" bone lesions (as demonstrated on the radiograph), hypercalcemia (causing the lethargy, weakness, and confusion in this case), and renal insufficiency (often causing polyuria and nocturia). Serum protein electrophoresis would demon- strate a monoclonal M spike, as opposed to a normal polyclonal distribution. The classic findings in osteoporosis are a significant loss of bone mass and vertebral fractures. Unlike multiple myeloma, osteoporosis does not produce "punched-out" lesions on radiographs. In addition, osteoporosis does not cause mental status changes, increased total protein levels, or polyuria. Diagnostic testing may include measurement of bone mineral density by dual-energy x-ray absorptiometry. In this technique the energy absorbed by dual x-ray beams is used estimate the surface area and density of mineralized tissue. Treatment includes surgical removal of the adenoma and biopsy of the remaining parathyroid glands to rule out parathyroid hyperplasia. However, the lytic skull lesions, hypercalcemia, and increased total protein level make multiple myeloma a far more likely diagnosis. Ankylosing spondylitis is a degenerative inflammation of the spine and sacroiliac joints, resulting in a stiff spine. Radiographs typically show forward curvature of the spine and fusion of the lumbar vertebrae, often referred to as a "bamboo spine. Many of these symptoms overlap with those seen in multiple myeloma; however, the increased total serum protein level and hypercalcemia seen in this patient are more typical of multiple myeloma. This patient suffers from McArdle disease, a glycogen storage disorder in which glycogen phosphorylase is deficient in muscle. The enzyme is responsible for liberating individual units of glucose-1-phosphate from branches of a glycogen molecule. Onset of the disease typically occurs in adolescence or early adulthood and is characterized by muscle cramping, rapid fatigue, and poor endurance during exertion. Lysosomal a-1,4-glucosidase is the defective enzyme in Pompe disease, another glycogen storage disorder. The findings in Pompe disease typically manifest in early childhood and include respiratory difficulties (due to diaphragmatic weakness), cardiomegaly, and progressive loss of muscle tone leading to early death. It can be caused by impaired synthesis or increased resorption of bone matrix protein. It is clinically associated with a postmenopausal state, physical inactivity, hypercortisolism, hyperthyroidism, and calcium deficiency. This patient has several risks factors for osteoporosis: She is postmenopausal and has a family history of osteoporosis, as evidenced by her mother, who fell at age 58 and needed hip replacement surgery. Her history of severe rheumatoid arthritis predisposes her to hypercortisolism as a result of treatment with corticosteroids. Lab tests in osteoporosis reveal normal serum calcium, normal serum phosphorus, and normal or decreased alkaline phosphatase levels. Treatments for osteoporosis include weight-bearing exercise, calcium supplementation, hormone replacement therapy, and bisphosphonates. These findings describe hypoparathyroidism, which may occur congenitally (DiGeorge syndrome) or after thyroidectomy. These lab values are seen in Paget disease, also known as osteitis Full-length exams Answer A is incorrect. It is implicated in Cori disease, which is a mild form of Von Gierke disease with normal blood lactate levels. Homocystinuria is an inborn error of metabolism caused by a defect in cystathionine synthase, the enzyme that converts homocysteine to cystathionine. In addition to Marfan-like features, these patients are at increased risk for a variety of cardiovascular derangements due to increased atherosclerosis, including premature vascular disease and early death. Glucose-6-phosphatase is the enzyme responsible for converting glucose-6-phosphate to glucose. A deficiency of this enzyme causes Von Gierke disease, characterized by a severe fasting hypoglycemia, increased test Block 2 Test Block 2 · Answers 543 deformans.

Diagnosis requires at least 2 of the following, and at least 1 of these should include 13 (first 4 are "positive symptoms"): 1. Negative symptoms (affective flattening, avolition, anhedonia, asociality, alogia) Brief psychotic disorder-lasting < 1 month, usually stress related. Schizoaffective disorder-Meets criteria for schizophrenia in addition to major mood disorder (major depressive or bipolar). To differentiate from a major mood disorder with psychotic features, patient must have > 2 weeks of hallucinations or delusions without major mood episode. Presents earlier in men (late teens to early 20s vs late 20s to early 30s in women). Negative symptoms often persist after treatment, despite resolution of positive symptoms. Functioning otherwise not impaired (eg, a woman who genuinely believes she is married to a celebrity when, in fact, she is not). Mood disorder Characterized by an abnormal range of moods or internal emotional states and loss of control over them. Severity of moods causes distress and impairment in social and occupational functioning. Includes major depressive disorder, bipolar disorder, dysthymic disorder, and cyclothymic disorder. Episodic superimposed psychotic features (delusions or hallucinations) may be present. Manic episode Distinct period of abnormally and persistently elevated, expansive, or irritable mood and abnormally and persistently activity or energy lasting at least 1 week. Bipolar disorder (manic depression) Bipolar I defined by presence of at least 1 manic episode +/- a hypomanic or depressive episode. Treatment: mood stabilizers (eg, lithium, valproic acid, carbamazepine, lamotrigine), atypical antipsychotics. Cyclothymic disorder-milder form of bipolar disorder lasting at least 2 years, fluctuating between mild depressive and hypomanic symptoms. Major depressive disorder Episodes characterized by at least 5 of the 9 diagnostic symptoms lasting 2 weeks (symptoms must include patientreported depressed mood or anhedonia). Persistent depressive disorder (dysthymia)- depression, often milder, lasting at least 2 years. Characterized by depressed affect, tearfulness, and fatigue starting 23 days after delivery. Characterized by mood-congruent delusions, hallucinations, and thoughts of harming the baby or self. Risk factors include history of bipolar or psychotic disorder, first pregnancy, family history, recent discontinuation of psychotropic medication. Grief the five stages of grief per the Kьbler-Ross model are denial, anger, bargaining, depression, and acceptance, not necessarily in that order. Other normal grief symptoms include shock, guilt, sadness, anxiety, yearning, and somatic symptoms. Simple hallucinations of the deceased person are common (eg, hearing the deceased speaking). Electroconvulsive therapy Used mainly for treatment-refractory depression, depression with psychotic symptoms, and acutely suicidality. Adverse effects include disorientation, temporary headache, partial anterograde/retrograde amnesia usually resolving in 6 months. Anxiety disorder Inappropriate experience of fear/worry and its physical manifestations (anxiety) incongruent with the magnitude of the perceived stressor. Symptoms interfere with daily functioning and are not attributable to another mental disorder, medical condition, or substance abuse. Includes panic disorder, phobias, generalized anxiety disorder, and selective mutism. Diagnosis requires attack followed by 1 month (or more) of 1 (or more) of the following: Persistent concern of additional attacks Worrying about consequences of attack Behavioral change related to attacks Symptoms are the systemic manifestations of fear. Specific phobia Severe, persistent (6 months) fear or anxiety due to presence or anticipation of a specific object or situation.

These processes, in conjunction with vasculitis, impairment of vascular autoregulatory mechanisms, and/or fluctuations of systemic blood pressure, lead to the development of ischemic, metabolic, and hypoxic cerebral lesions (focal necrosis, territorial infarction). Immune prophylaxis: Vaccines are available against Haemophilus influenzae type B infection (for infants, small children, and children over 6 years of age at increased risk), Pneumococcus (children over 2 years of age and adults with risk factors such as immunosuppression or asplenia), and meningococcus (travel to endemic regions, local outbreaks). Chemoprophylaxis is indicated for close contacts of persons infected with Haemophilus influenzae (rifampicin) or meningococcus (rifampicin, ciprofloxacin, or ceftriaxone). Brain Abscess Brain abscess begins as local cerebritis and is then transformed into an encapsulated region of purulent necrosis with perifocal edema. The pathogenic organisms may reach the brain by local or hematogenous spread (mastoiditis, otitis media, sinusitis, osteomyelitis; endocarditis, pneumonia, tooth infection, osteomyelitis, diverticulitis), or by direct inoculation (trauma, neurosurgery). The clinical manifestations include headache, nausea, vomiting, fever, impairment of consciousness, and focal or generalized epileptic seizures, neck stiffness, and focal neurological signs. Bacterial endocarditis causes cerebral abscess formation or infarction by way of infectious thromboembolism (¶ focal inflammatory changes in the cerebral parenchyma ¶ metastatic or embolic focal encephalitis). The syndrome is characterized by headache, fever, epileptic seizures, and behavioral changes in addition to focal neurological signs. Embolization of infectious material may lead to the development of septic ("mycotic") aneurysms. Bacterial thrombophlebitis of the cerebral veins or venous sinuses may arise as a complication of meningitis or by local spread of infection from neighboring structures. The clinical findings are often nonspecific (somnolence, impairment of concentration and memory). Abdominal complaints (peritonitis) may predominate if the infection has spread down a ventriculoperitoneal shunt to the abdomen. Septic Encephalopathy Bacteremia leads to the release of endotoxins, which, in turn, impair cerebral function. Encephalitis occurs relatively rarely and may cause focal neurological deficits as well as behavioral changes (impaired concentration, personality changes, depression). Myelitis, when it occurs, often affects the spinal cord at the level of a radicular lesion. Few patients ever reach this stage, characterized by neurological deficits such as ataxia, cranial nerve palsies, paraparesis or quadriparesis, and bladder dysfunction (Lyme encephalomyelitis). Encephalopathy causing impairment of concentration and memory, insomnia, fatigue, personality changes, and depression has also been described. The diagnosis of Lyme disease is based on the presence of erythema chronicum migrans, the immunological confirmation of Borrelia infection. By definition, the diagnosis also requires the presence of lymphocytic meningitis (with or without cranial nerve involvement or painful polyradiculoneuritis), encephalomyelitis, or encephalopathy. A vaccine has been approved for use in the United States, and another is being developed for use in Europe. The probability of infection is low unless the infected tick remains attached to the skin for at least 2448 hours. Up to 90 % of all patients develop a painless, erythematous macule or papule that gradually spreads outward from the site of the tick bite in a ringlike or homogeneous fashion (erythema chronicum migrans). This is commonly accompanied by symptoms due to hematogenous spread of the pathogen, such as fever, fatigue, arthralgia, myalgia, or other types of pain, which may be the chief complaint, rather than the skin rash. Regional or generalized lymphadenopathy (lymphadenosis benigna cutis) is a less common presentation. Generalized symptoms such as fatigue, anorexia, muscle and joint pain, and headache develop in 1015 % of patients within ca. Neurological manifestations: Cranial nerve palsies, painful polyradiculitis and lymphocytic meningitis (Bannwarth syndrome, meningopolyneuritis) are commonly seen in combination. One or more cranial nerves may be affected; the most common finding is unilateral or bilateral facial palsy of peripheral type. Neuroborreliosis-related polyradiculoneuropathy (which may be mistaken for lumbar disk herniation) is characterized by intense pain in a radicular distribution, most severe at night, with accompanying neurological deficits (motor, sensory, and reflex abnormalities, focal muscle atrophy). Borrelia-related meningitis (Lyme meningitis) usually causes alternating headache and neck pain, but the headache is mild or absent in some cases. Infection Stages of Lyme disease Rohkamm, Color Atlas of Neurology © 2004 Thieme All rights reserved. Chronic meningoencephalitis with progressive paralysis occurs 1025 years after the initial infection. The "preparalytic" stage, characterized by personality changes and mild impairment of concentration and memory, later evolves into the "paralytic" stage, characterized by more severe cognitive changes, dysarthria, dysphasia, tremor (mimic tremor), apraxia, gait impairment, urinary incontinence, and abnormal pupillary reflexes (roughly 25 % of patients have ArgyllRobertson pupils, p. This late meningovascular complication (2530 years after the initial infection) produces ocular manifestations (ArgyllRobertson pupils, strabismus, papillary atrophy), pain (lightning pains = lancinating pain mainly in the legs; colicky abdominal pain), gait impairment (due to loss of acrognosis and proprioception), and autonomic dysfunction (impotence, urinary dysfunction). The efficacy of treatment depends on the stage of disease in which it is instituted (the earlier, the better). Other routes of transmission, such as the sharing of needles by intravenous drug users, are much less common. Tertiary stage (currently rare): After an asymptomatic period of a few months to years (latent syphilis), organ manifestations develop, such as gummata (skin, bone, kidney, liver) and cardiovascular lesions (aortic aneurysm). The first year of the tertiary stage is designated the early latency period and is characterized by a high likelihood of recurrence and, thus, recurrent infectivity. Fluctuating symptoms such as headache, visual disturbances, and vertigo occur 512 years after the initial infection. Hydrocephalus, personality changes, epileptic seizures, and spinal cord signs (paraparesis, bladder dysfunction, anterior cord syndrome) round out the kaleidoscopic clinical picture. Infection Development of symptoms of neurosyphilis (no fixed time course) 231 Rohkamm, Color Atlas of Neurology © 2004 Thieme All rights reserved. Chronic meningitis most likely reflects inadequate treatment, or resistance of the pathogen, rather than being a distinct form of the disease. Tuberculoma is a tumorlike mass with a caseous or calcified core surrounded by granulation tissue (giant cells, lymphocytes). Tuberculomas may be solitary or multiple and are to be differentiated from tuberculous abscesses, which are full of mycobacteria and lack the surrounding granulation tissue. Transverse spinal cord syndrome can arise because of tuberculous myelomeningoradiculitis, epidural tuberculous abscess associated with tuberculous spondylitis/ discitis, or tuberculoma. One treatment protocol specifies a combination of isoniazid (with vitamin B6), rifampicin (initially i. After 3 months, pyrazinamide is discontinued, and treatment with isoniazid and rifampicin is continued for a further 69 months. Mycobacterium tuberculosis transmission in man is usually by transfer of droplets from and to the respiratory tract (rarely orally or through skin lesions). The pathogen replicates in the lungs (primary infection), either in the lung tissue itself or within alveolar macrophages.

Albert and Jьrg Kesselring Introduction and overview Stroke is one of the most common causes of longterm disability in adults, especially in elderly people. The overall benefit of stroke units results not only from thrombolysis only a small proportion of all stroke patients (less than 10%) are treated with this regimen but more generally from the multidisciplinary stroke unit management, including treatment optimization, minimization of complications, and elements of early neurorehabilitation [1, 2]. After the acute treatment, stroke patients with relevant neurological deficits should in general be treated by a specialized neurorehabilitation clinic or unit. Neurorehabilitation nowadays is considered as a multidisciplinary and multimodal concept to help neurological patients to improve physiological functioning, activity and participation by creating learning situations, inducing several means of recovery including restitution, functional remodeling, compensation and reconditioning . A key point in successfully diminishing negative long-term effects after stroke and achieving recovery is the work of a specialized multidisciplinary team (physicians, nursing staff, therapists, others) with structured organization and processes and the stroke patient taking part in a multimodal, intense treatment program which is well adapted in detail to the individual goals of rehabilitation and deficits. There is growing evidence indicating a better outcome of neurorehabilitation in stroke with early initiation of treatment, high intensity, specifically aimed and active therapies and the coordinated work and multimodality of a specialized team . Neuroplasticity Mechanisms of neuroplasticity While for many decades of the last century it was believed that, "once development is complete, the sources of growth and regeneration of axons and dendrites are irretrievably lost. In the adult brain the nerve paths are fixed and immutable: everything can die, nothing can be regenerated" , a paradigm shift has taken place. A few years later in 1936 it was reported that therapeutic exercises influence the course of spontaneous recovery of a brain affection . It has been a long way, however, to what we now know, first by measurement of the effects of rehabilitation, that the central nervous system of the adult human being has an astounding potential for recovery and adaptability, which can be selectively promoted . The extent of recovery in stroke is dependent on many factors, the initial size and location of the cerebral lesion being the predominant factor. As an exception, in severe disorders recovery can vary and these patients may even show onset of functional recovery after a longer period . Such recovery of the central nervous system over the course of time after the onset of stroke is possible 283 Section 4: Therapeutic strategies and neurorehabilitation 284 due to a mechanism described as neuroplasticity, which can be observed and investigated by different approaches. Hebb first described neuroplasticity with regard to the function of synapses , and later this principle was also linked to the functioning of neurons in the wider context of neuronal networks. Several (overlapping and interacting) mechanisms of neuronal plasticity can be identified [7, 911], which include: Vicariation (vice ј instead of) describes the hypothesis that the functions of damaged areas can be taken over by different regions of the brain. In clinical practice this ability may vary widely and may be insufficient for a large group of patients with remaining difficulties after brain damage. With functional imaging, however, it could be demonstrated that vicariation takes place in cortical representation areas. Another clinical example is the change in lateralization of speech in some younger patients. Plasticity of areas of cortical representation was described in animal models in connection with the variable size of cortical representation "loco typico" of motor fields [12, 13]. Later such enlargement of cortical representations was also demonstrated in humans. In an illustrative longitudinal study , a small group of stroke patients with comparable circumscribed M1 lesions (similar to experimental lesions in animal models) affecting the motor control of the contralateral hand were assessed over several months. After several months, activation was again ipsilesional and closer to the former representation and more dorsal for the function of finger-extension as compared to controls, reflecting functional reorganization in the motor cortex adjacent to the lesion. Enhanced activity of the ipsilesional primary motor cortex induced by motor training is paralleled by improved motor function . For better understanding of these mechanisms a main strategy for recovery in such patients seems to be the goal of achieving the best results by recruitment and adaptation of surviving secondary motor areas in both hemispheres : in addition to a static point-bypoint view of the somatotopic organization of the motor homunculus recent studies also demonstrate the representation of movements within the primary sensorimotor cortex, and, on the other hand, secondary motor areas have direct projections to spinal cord motor neurons, although they are less numerous than those from M1. A persistent activation, however, of many different areas may also indicate a less successful or failed reorganization in chronic stroke patients: the higher the involvement of the ipsilesional motor network, the better the recovery. In this respect interaction between lesional and contralesional hemispheres may also play an important role . Basic underlying mechanisms of these findings include both different functional use of existing networks and synapses, but also to a certain extent structural changes.
