N Anatomy the hair follicle is divided into three parts: the infundibulum, isthmus, and inferior portion. The infundibulum is the most superficial part and joins the isthmus where the duct of the associated sebaceous gland enters the follicle. The isthmus is separated from the inferior portion by the insertion of the arrector pili muscle. Hair grows naturally in groupings or units of 1, 2, 3, or 4 hairs associated with a sebaceous gland and an arrector pili muscle. The inferior portion of the hair elongates and forms the matrix containing bulb and papilla. Catagen (lasts 23 weeks): the inferior portion of the hair ascends to the level of the arrector pili muscle. Differential Diagnosis Other rare causes of alopecia include alopecia areata (autoimmune), telogen effluvium (possibly stress related), secondary syphilis, trichotillomania, traction alopecia, and hair breakage due to aggressive grooming or chemical treatments. Hair density at occipital donor site ideally should be greater than 8 hairs per 4 mm diameter if the patient is to undergo transplant. Darker skin with curly, coarse dark hair or lighter skin with curly, coarse salt and pepper hair are the best transplant combinations. Facial Plastic and Reconstructive Surgery 679 Relevant Pharmacology Minoxidil (Rogaine): Opens K channels and directly vasodilates peripheral vessels. Surgery Scalp reduction (removal of nonhair-bearing scalp) and scalp flaps for hair rearrangement are falling out of favor except in selected cases. The mainstay of therapy is hair transplantation with (1) harvest of occipital hair, (2) primary closure of the donor site and microscopic dissection of donor hair into follicular unit grafts, and (3) placement of 800 to 1600 follicular unit grafts (14 hairs per graft) via stab incisions. Hair must be placed at the appropriate site and angle to the skin to recreate a natural look. Only micrografts (12 hairs per graft) should be placed along the anterior hairline, which should be 7 to 8 cm above the brows. N Complications Complications for hair transplantation are rare (less than 5%) and include cobblestoning, folliculitis, graft failure, and donor site scarring. N Outcome and Follow-Up For hair transplantation, patients can shower postoperative day 1 and wash hair postoperative day 2. Transplanted hairs will fall out in 2 to 3 weeks and begin new growth at 3 to 4 months postprocedure. Typically, 3 to 5 sessions (at least 6 months apart), each with placement of 800 to 1600 grafts are necessary for complete treatment. Patient must continue minoxidil and finasteride to see continued results from these medicines. Basic Procedures and Methods of Investigation 681 Appendix A Basic Procedures and Methods of Investigation N A1 Bronchoscopy Two methods of bronchoscopy are available rigid and flexible. Rigid bronchoscopes are tubes of different calibers with a proximal cold light source. The bronchoscope has direct connection to the anesthetic and respiratory apparatus, so it is called the respiratory bronchoscope. A rigid bronchoscope can be combined with other instrumentation, including aspiration lavage, cytologic diagnosis, and swabs for culture. Indications Rigid bronchoscopy as a therapeutic measure: G G Emergency bronchoscopy done to bypass sudden obstructive respiratory insufficiency Removal of tracheal or bronchial foreign body; arrest of bleeding of the trachea or bronchi Rigid bronchoscopy as a diagnostic procedure: G G G G To treat tracheal or bronchial stenosis To biopsy a tracheal tumor To investigate hemoptysis To assess upper airway trauma Advantages G G G Versatile procedure Can be used on a bleeding patient Extraction of foreign body Disadvantages G G G Technically more difficult with abnormal cervical anatomy Limitations on neck extension Must be done under general anesthetic 682 Handbook of OtolaryngologyHead and Neck Surgery Flexible Bronchoscopy Flexible bronchoscopes usually have a diameter of between 4 to 5 mm and are thinner than rigid bronchoscopes. Their distal end is controlled externally so they can be introduced into the low bronchi or segmental bronchi. Flexible bronchoscopy may be performed under local or general anesthetic with the patient sitting or lying. When using general anesthetic, at intubation the bronchoscope may be introduced through the endotracheal tube. Indications G G G G Bronchial or upper airway tumors Hemoptysis Undiagnosed disorders such as unresolved pneumonia Middle lobe syndrome Advantages G G It can be introduced far into the periphery as far as the fifth generation bronchi; therefore, it complements the rigid endoscope. Disadvantages G It has a relatively narrow working radius; therefore, it cannot be used for large foreign bodies or in the presence of profuse bleeding. Complications Complications of rigid and flexible bronchoscopy include: G G G G G Damage to vocal folds Perforation of tracheobronchial tree Pneumothorax Laryngospasm Death N A2 Esophagoscopy Esophagoscopy can be performed with either a rigid or flexible esophagoscope. The rigid esophagoscope is a rigid tube that is usually used under general anesthesia. Extraction, excision, and coagulation instruments can be used in conjunction with the rigid esophagoscope. Flexible esophagoscopy has a narrow caliber, is suitable for foreign body extraction, and can be used in conjunction with air insufflation and be attached to air insufflation and suction. It also typically provides good photographic documentation for permanent record keeping. Indications Rigid esophagoscopy as a therapeutic measure: G G G G G Removal of foreign bodies Removal of polyps and fibromas Division of hypopharyngeal rings and diverticulum Dilation stenosis Injection of esophageal varices Rigid esophagoscopy as a diagnostic procedure: G G G To diagnose diseases of the esophagus To diagnose tumors of the hypopharynx and esophagus To evaluate dysphagia Flexible esophagoscopy as a diagnostic procedure: G G In cases where rigid esophagoscopy is contraindicated or impossible due to an ability to flex or extend the neck because of cervical spine disease, panendoscopy is indicated. Advantages Rigid esophagoscopy: G Versatility and superior ability to remove large foreign bodies from the esophagus. Flexible esophagoscopy: G G G Simultaneous panendoscopy of the stomach and duodenum may be performed. Good screening instrument Less traumatic for the patient Complications G G G G G G Esophageal perforation False passage Mediastinitis Pneumomediastinum Oral and dental injury, especially with use of rigid instrumentation Death 684 Handbook of OtolaryngologyHead and Neck Surgery N A3 Rigid Direct Microscopic Laryngoscopy with or without Biopsy this is used for larynx and hypopharynx evaluation and biopsy.

Subciliary Approach the transcutaneous subciliary approach employs an external incision just below the eyelashes (high erectile dysfunction drugs online order generic apcalis sx on line, immediately subciliary erectile dysfunction 38 years old buy apcalis sx 20 mg, or relatively lower to psychological reasons for erectile dysfunction causes generic 20 mg apcalis sx otc preserve the pretarsal orbicularis muscle). A skinmuscle flap technique is the preferred method when resection of the orbicularis muscle and skin is indicated the incision is through the skin followed by elevation, and possible fat removal. Fat removal requires the discrete separation of muscle fibers over each fat compartment and incising through the orbital septum. Closure involves lateral and superior elevation with resuspension of the orbicularis muscle. Fat may be removed from the lateral compartment first, followed by the central and then medial compartments. Fat may be infiltrated with 664 Handbook of OtolaryngologyHead and Neck Surgery additional nonepinephrine containing local anesthetic prior to cautery and removal. Advantages of the subciliary approach include a relatively avascular plane with a minimal risk of skin penetration, and additional tightening via skin muscle suspension using sutures from the lateral orbicularis muscle to the lateral orbital region. Limitations of the subciliary approach include a possible increased risk of ectropion. The surgeon may use surgical tape to counter the gravitational effect of postoperative edema, external scar, hematoma, or bruising as a result of orbicularis muscle dissection. Transconjunctival Approach Lower eyelid blepharoplasty is centered on the removal of redundant pseudoherniated fat with incision on the inner aspect of the eyelid. The ideal candidate is 20 to 30 years of age with significant pseudoherniation of fat, minimal skin excess, and minimal orbicularis hypertrophy. This approach is especially helpful to use in patients with tight, inelastic lower eyelids exhibiting scleral show, as this approach transects and releases inferior retractor muscles. The incision is in the lower eyelid conjunctiva with avoidance of disruption of orbicularis muscle. The preseptal approach involves placing the incision high along the inner eyelid conjunctiva with dissection anterior to orbital septum and under the orbicularis muscle. It is important to protect the cornea while dissecting behind the orbicularis muscle. Exposure of the surgical site and globe protection is facilitated with the use of nonconducting retractors. The dissection is continued downward and forward until all the pseudoherniated fat is exposed. Fat is removed to a depth 1 mm below the surface of the orbital rim with gentle pressure placed on the globe to assess for irregularity and asymmetry. Skin may be resected as necessary using the "pinch" technique or may be combined with chemical peel or laser resurfacing to address superficial fine-line rhytides. Transection of lower lid retractors may have the lower lid margin appear elevated for a few weeks. Advantages of the transconjunctival approach include avoidance of external scar, and potentially less risk of ectropion. Limitations include lack of addressing skin excess or hypertrophy of the orbicularis muscle. Lower eyelid blepharoplasty is associated with a higher rate of hematoma formation. It may occur up to a few days postoperatively and is treated with a lateral canthotomy and orbital decompression. Blindness Chronic G G G G G G G Ectropion Lagophthalmos Scleral show Ptosis Epiphora Inadequate excision of skin and fat Dry eyes Further Reading Bosniak S. The lateral skin is tightly adherent to the cartilage, whereas the medial or postauricular skin has loose connective tissue subcutaneously and thus can be easily separated and peeled from the underlying concha and scapha. The lobule has no cartilage and can have several anatomic configurations and positions. The abnormal development that results in deformities of the auricle usually originates from the second branchial arch. These abnormalities usually manifest themselves before the end of the first trimester of pregnancy; the frequency of variants is from 3 to 5% of the Western population. Also, aging makes the auricle appear larger, in part due to elongation of the lobule. N Evaluation of Aesthetic Deformities of the Auricle the helix, scapha/antihelix, posterior conchal wall, and conchal floor make up the four planes of the auricle. The angles between these planes and the auricle or scalp determine the degree of protrusion of the ear. The degree of protrusion or malformation is described as a variant from the normal conchascapha angle. Normal ears have a conchascapha angle of 75105 degrees, with 90 degrees most common. An ear is classified as "protruding" when the conchascapha angle 110 degrees, the angle of the ear to scalp 40 degrees, or the helical rim protrudes 3 cm. N Surgical Techniques Treatment of abnormally shaped ears commonly addresses two concerns: the lack of development of the antihelical fold and the deep concha cavum, respectively. The Mustarde-type approach utilizes permanent sutures to recreate the antihelical fold. The second approach utilizes scoring incisions, abrading, or filing the cartilage to alter its shape thus reestablishing a fold. A combination of the techniques may be utilized particularly if the scapha is resistant to reshaping via the suture placement. One is the Furnas-type approach of suturing posterior conchal cartilage to the mastoid periosteum. The other techniques involve excisions of conchal cartilage usually performed through the postauricular incision. The excisions can be elliptical or crescent-shaped with reapproximation of the cartilage or they can be disk shaped when combined with the conchal setback techniques. The goal is to reduce the height of the posterior conchal wall, thus reducing the prominence of the ear. Facial Plastic and Reconstructive Surgery 667 In the majority of patients, the permanent suture technique is utilized with or without scapha weakening. Deep conchal bowls are reduced by elliptical posterior cartilage excisions of 3 to 5 mm and usually followed by a conchal setback procedure. The procedure is done under general anesthesia in children and local anesthesia with sedation in adults. The incision is placed above the postauricular sulcus in an intermediate location between the mastoid and postauricular skin and the edge of the auricle. When reducing the conchal bowl, perform this first by excision of 3 to 5 mm and reapproximating the edges with 5-0 clear Prolene. The edges are undermined to avoid bunching of the skin, but not so extensively as to create conditions for hematoma formation. The creation of the antihelical fold is done by folding the auricle and noting the location for suture placement necessary to create the fold. The locations are then marked externally and internally prior to suture placement. The sutures are placed (usually two or three) in horizontal mattress fashion and are tied after all are placed.

However erectile dysfunction videos generic apcalis sx 20 mg otc, before commencement of such detailed investigations erectile dysfunction treatment diabetes order apcalis sx 20mg on line, patients with a clear evidence of chronic organic disease should be evaluated and treated for their primary illness erectile dysfunction depression treatment order 20mg apcalis sx with visa. Those on drug therapy that is likely to be responsible for their erectile problem should have their medications changed or discontinued for a trial period while assessing for the return of potency. Discontinuation of substance abuse before a full diagnostic workup is also required (Hatzichristou et al, 2002; Sadovsky, 2000; Broderick, 1999). Investigation of structural abnormalities of penis; Several techniques are available for evaluation of structural and functional integrity of the penile tissue. Biopsy may be helpful in case where corporeal fibrosis is suspected (Hussain,1998). Normal nocturnal tumescence has been defined as a total night erection time greater than 90 min and an increase in penis circumference in excess of 2 cm. A change in circumference of 16 mm or 80% of a full erection is thought to reflect a sufficient degree of penile rigidity for vaginal intromission. A buckling pressure less than 60 mm Hg is thought to be inadequate for vaginal penetration. Vascular investigations: Patients suspected of having vascular lesions, based on history, physical signs, and those with abnormal tumescence monitoring, may undergo more detailed vascular evaluation of the penile vasculature to determine whether a surgically correctable factor underlies the dysfunction. Neurological investigations: As we know that sexual functioning is controlled by autonomic nervous system several neurological assessments have been developed to assess the role of autonomic disorders in the development of sexual dysfunction. These include biothesiometry (assesses vibration perception threshold), dorsal nerve conduction velocity, bulbocavernosus reflex (sacral reflex arc) latency, Pudendal nerve somatosensory (genitocerebral)-evoked potential and Perineal electromyography. Pudendal nerve somatosensory (genitocerebral)-evoked potential test allows the evaluation of the peripheral and suprasacral afferent pathways by stimulating the pudendal nerve at the penis. Patients with sacral lesions (distal to the sacral recording electrodes) caused by multiple sclerosis, spinal cord trauma, or tumor may demonstrate prolonged peripheral and total conduction times. However, patients with suprasacral lesions (cephalic to recording electrodes) caused by transverse myelitis, cervical disc disease, tumor, or trauma may have prolonged total conduction time and central conduction time, but normal peripheral conduction time (Padma-Nathan, 1986). Some of the basic principles of patient centered approach are given in Table-14 (Ralph & McNicholas, 2000). Table-14: Principles of treatment · · · For most patients, the final selection of treatment should be according to their choice. The role of the professional is to inform the patient & help him to make a reasoned choice. The professionals should provide unbiased information on all suitable treatment options, their merits, and known significant risks, in a form that the patient (and partner) can assimilate and from which it is sufficient for them to evaluate the options. The final choice of treatment is tailored to the needs and preferences of the patient. At times clinicians are faced with situations when patients are not able to bring a partner for the treatment. In such cases no patient should be denied treatment because of the absence of a current partner. Agreed treatment goals should be established at the start of treatment Appropriate information should be given on management of the chosen treatment, including advice on what to do & whom to contact in case of problems and complications. This can be a source of encouragement, especially if the therapist also explains how common such problems are. Second, the therapist should point out the likely contributory factors, particularly the maintaining factors which will be the focus of therapy, and thus establish a rationale for the treatment approach. Finally, providing a formulation also helps to check that the information obtained during the assessment has been correctly interpreted. So the couple should always be asked to give a feedback of the formulation (Hawton, 1989). It is important for the therapist to strike a balance between individual partners contribution to the problem, and thus emphasize the need of collaboration between the partners for the success of the therapy. Treatment options: Treatments can be broadly classified into general measures and specific measures. The specific measures can be either pharmacological measures, non-pharmacological measures or a combination of both. Unfortunately there are no well designed studies which have evaluated the effectiveness of these psychotherapies. Among all the techniques, which have been used, cognitive behavioural measures of Master Johnson or its modifications are the most popular and have been found to be most useful. In the recent time there is lot of research on the pharmacological measures for treatment of sexual dysfunction, especially erectile dysfunction. Now many pharmacological options are available for treatment of sexual dysfunctions in both males and females and well designed studies have shown that they are efficacious. Selection of treatment: As discussed earlier, the final selection of treatment should be according to their choice. The therapist should inform the patient about the available modalities and help him to make a reasoned choice. The treatment can be broadly classified as general behavioural measures, specific behavioural management and pharmacotherapy. The specific behavioural measures involve nongenital sensate focus, genital sensate focus and vaginal containment for the couples (for single males the steps are different and are discussed later). Further specific behavioural measures for the specific disorders are usually based on the type of disorder. Selection of pharmacological agents should take into consideration associated psychiatric comorbidity, physical comorbidity and age of the patient. Material used for the sex education should cover information about the anatomy of the sex organs, menstrual cycle, pregnancy, puberty, masturbation, formation of semen, night falls, types of sex, stages of sexual intercourse, normal male and female sexual response cycle. Although all the areas should be covered, special emphasis should be given to those areas, which are directly related to the illness. Where ever possible figures and diagrams should be used for reference and illustrations. Sex education and teaching relaxation should be carried out over the four sessions. Discuss about anatomy of the sex organs Discuss about menstrual cycle, pregnancy, puberty, masturbation, formation of semen, nightfalls, types of sex, stages of sexual intercourse, normal male and female sexual response cycle. Educate the patient/couple about the wide variation in the extent and frequency of feelings of sexual desire from one individual to the next. Educate patient/couple that sex will sometimes be refused and that the refusal is not necessarily an insult or a personal rebuff. If culturally appropriate, encourage partners to accept the use of masturbation or manual stimulation if sexual advances are refused. Educate patient/couple about the fact that sexual desire levels fluctuate over the life span. Encourage patient/couple to communicate their needs for desire and sexual arousal. Encourage patient/couple to show each other what sort of stimulation is required for orgasm to occur. Educate males that some females may be able to have multiple orgasms (especially if a vibrator is used) and hence may sometimes find it pleasurable if genital stimulation is continued after the initial orgasm.

Evaluation for appropriate posttotal laryngectomy communication is multifactorial impotence workup generic apcalis sx 20 mg free shipping. The three primary options for communication are the electrolarynx erectile dysfunction drugs injection order apcalis sx 20mg, tracheoesophageal puncture erectile dysfunction drugs boots order 20 mg apcalis sx with amex, and esophageal speech. Head and Neck 399 Surgery to the larynx, whether in the form of total or partial laryngectomy, has the potential to greatly impact the vocal communication system. Partial laryngeal surgery often requires intensive vocal rehabilitation, and full functionality may never be regained. Total laryngectomy results in aphonia, and there are several communication options to replace this function. N Epidemiology the annual incidence of diagnosed head and neck cancer in the United States is 45,660 cases. Cancers diagnosed in the first or second stage are more likely to be treated with local surgical excision or chemoradiation therapy; cancers of the larynx in the third or fourth stage are more likely to result in a total removal of the larynx in combination with chemotherapy and radiotherapy. Of the three communication options postlaryngectomy, 55% of individuals use an electrolarynx as a primary communication method, 31% use a tracheoesophageal puncture prosthesis, and 6% use the esophageal speech method (8% remain nonvocal). N Clinical Signs and Symptoms Following partial laryngeal surgery, patients often present with dysphonia characterized by a weak, strained, or breathy vocal quality. Patients who have had a total laryngectomy have a total inability to phonate postoperatively secondary to removal of the larynx, including the vocal folds. Differential Diagnosis In patients with partial laryngeal surgery, it is important to determine whether the current vocal qualities are a result of surgical treatment versus an advancement or recurrence of the carcinoma. Any change in previous alaryngeal communication abilities of individuals following a total laryngectomy can indicate recurrence of cancer and should be carefully evaluated. N Evaluation Evaluation for communication methods following total laryngectomy include an evaluation of physical changes from surgery and chemoradiation therapy to assess for the ability for electronic larynx placement either transcervically (neck-type) or intraorally (mouth-type), stoma size and placement for stomal occlusion with tracheoesophageal puncture voicing. Additionally, manual dexterity, motivation level, and financial/insurance resources should be considered. After Total Laryngectomy Electrolarynx A battery-powered electronic device called an electrolarynx is used. Depending on anatomic changes following surgery, an electrolarynx can be placed either transcervically (neck-type) or intraorally (mouth-type). The electrolarynx produces a vibration that is transmitted intraorally through a straw attached to the device or through the tissues of the neck or cheek. The electrolarynx offers a communication option immediately after surgery, is relatively easy to use, and has a lower one-time cost (when compared with the tracheoesophageal puncture voice prosthesis). Disadvantages include a mechanical sound quality, requirement for one free hand during communication, and unfamiliarity of the sound by most listeners. Tracheoesophageal Puncture Voice Prosthesis For the tracheoesophageal puncture voice prosthesis, a small fistula is surgically placed in the tracheoesophageal wall, 1 cm below the upper lip of the stoma. Voicing is then achieved by passing air from the trachea to the esophagus via stomal occlusion with either manual finger occlusion or a hands-free stomal attachment. The voice prosthesis allows for an esophageal sound production, which is then shaped by the oral cavity for speech production. Individuals with a laryngectomy often feel this method allows for speech to be most comparable to preoperative speech in terms of quality, fluency, and ease of production. Anatomic variations include hypertonicity or flaccidity of the pharyngoesophageal muscle segment, stomal stenosis, or stoma irregularity. Mechanical problems include size, fit, and prosthesis breakdown secondary to Candida infection or gastroesophageal reflux disease, or dislodgement. Other disadvantages include the cost of the prosthesis (which must be replaced every few months), accessibility to a speech-language pathologist or otolaryngologist trained to change and maintain indwelling valves, and manual dexterity for cleaning and management. Esophageal Speech Speech is produced from a learned method of vibrating the pharyngoesophageal muscle segment. Air is introduced into the esophagus through the oral cavity and is then passed back out of the esophagus past the 5. This can be done using either a glossopharyngeal press method or an inhalation method. Esophageal speech allows for communication without the use of mechanical or prosthetic devices and allows for more natural sound production. Disadvantages include an increased time period for learning this method (estimated 4 to 6 months of regular speech therapy and daily practice), limited success rates, and decreased ability to control volume. N Outcome and Follow-Up Any patient with laryngeal carcinoma must follow up with an otolaryngologist for at least 5 years postoperatively. A patient with an indwelling tracheoesophageal puncture voice prosthesis must follow up with a speech-language pathologist or otolaryngologist trained in prosthesis management for all changes, approximately every 3 months. Additionally, follow-up should occur immediately for prosthesis dislodgement or significant change in sound quality, as this can indicate a more significant problem, recurrence, aspiration, or may allow tract stenosis or closure. Compliance, quality of life and quantitative voice quality aspects of hands-free speech. Looking Forward: the Speech and Swallowing Guidebook for People with Cancer of the Larynx or Tongue. If no otic source for otalgia can be identified malignancy must be investigated and excluded. By definition, referred otalgia is the sensation of ear pain originating from a source outside the ear. Many remote anatomic sites share innervations with the ear, and noxious stimuli to these areas may be perceived as otalgia. N Evaluation the evaluation of a patient with otalgia begins with a detailed history and a thorough head and neck examination. Head and Neck 403 timing of the otalgia, exacerbating and alleviating factors of the otalgia, the patients past otologic history, the associated symptoms with the otalgia (tinnitus, hearing loss, vertigo), the presence of constitutional symptoms (to detect malignancies), and sinus and dental questions. A thorough otologic examination, with a tuning fork test at two frequencies (256 and 512 Hz), is important. The nose, sinuses, oral cavity, oral pharynx, and neck are inspected and palpated to look for sources of referred otalgia. In assessing otalgia in the setting of a normal otologic examination, a fiberoptic nasopharyngolaryngoscopy is mandated to look for lesions that can be potentially noxious to the trigeminal, facial, glossopharyngeal, or vagus nerves. Attention should be directed to the endolarynx to examine the mucosa for signs of malignancy and gastroesophageal reflux. N Treatment Options Appropriate treatment of the source of otalgia in combination with pain management. Neck dissection or lymphadenectomy is a surgical procedure in which the fibrofatty contents of the neck are removed for the prevention or treatment of cervical metastasis. Most commonly used in the treatment of cancers of the upper aerodigestive tract, skin of the head and neck, thyroid, and salivary glands. The term "neck dissection" refers to the systematic removal of lymph nodes in the neck. To eradicate cancer in the cervical lymph nodes and to help determine the need for additional therapy (staging) when no lymph nodes are clinically identified, neck dissection may be performed.

Multinucleate giant cells impotence is a horrifying thing buy cheap apcalis sx on line, spindle-shaped cells impotence jokes purchase cheap apcalis sx on-line, and squamoid cells usually predominate erectile dysfunction treatment milwaukee 20mg apcalis sx free shipping. Treatment Surgical treatment may consist of complete resection in selected individuals when possible followed by a combination of chemotherapy and radiotherapy. Often, the tumor is not resectable, and surgery consists of a tracheotomy or cricothyroidotomy to prevent airway compromise. Radiation therapy is indicated preoperatively to increase the tumor resectability rate, postoperatively to enhance the effect of chemotherapy or to alleviate obstruction, but its efficacy must be balanced against its toxicity. Calcitonin is secreted by the tumor and is a useful marker for diagnosis and follow-up. Clinical Presentation Medullary thyroid cancer typically presents as a painful hard nodule or mass in the thyroid gland or as an enlargement of the regional lymph nodes. Sometimes, it comes to medical attention due to a metastatic lesion at a distant site. Pathology Characteristic microscopic features are sheets of cells separated by a pinkstaining substance that has characteristics of amyloid. Diagnosis can be confirmed by positive immunostaining of the tumor tissue for calcitonin and carcinoembryonic antigen. Preoperatively, patients should also be evaluated for hyperparathyroidism and for pheochromocytoma. Total thyroidectomy with removal of regional lymph nodes should be performed after excluding hyperparathyroidism and pheochromocytoma. An elevated basal serum calcitonin 6 or more months after surgery indicates residual disease. In cases of advanced metastatic disease untreatable by surgery or radiation, cytotoxic chemotherapy, somatostatin analogues, and interferon or radioimmunotherapy may provide palliation. Clinical Presentation Usually thyroid lymphoma presents as a rapidly enlarging goiter. Patients may experience symptoms or signs of compression of the trachea or esophagus, including dysphagia, dyspnea, stridor, hoarseness, and neck pain. On physical examination, the thyroid is usually firm, slightly tender, and is fixed to surrounding structures. In addition, 10% of patients have systemic (B) symptoms of lymphoma, including fever, night sweats, and weight loss (10% of body weight or more). Patients may also present with symptoms and signs of hypothyroidism or hyperthyroidism. Head and Neck 491 lymphoma from chronic thyroiditis; often surgical specimens are required for diagnosis. Pathology, immunohistochemical staining, or flow cytometry may be necessary to establish monoclonality and characterize surface markers, especially to diagnose small cell lymphomas. Treatment Surgery is not the primary treatment and is typically used for diagnostic biopsy and surgical airway only. If disease is confined to the neck, treatment is guided by the histologic features of the lymphoma. Patients with large cell lymphoma are treated with chemotherapy with or without radiation. For patients with localized extranodal marginal zone lymphoma of the thyroid, follicular lymphoma and small cell lymphoma radiotherapy alone may be adequate. The lymph nodes must be specifically identified to classify regional node involvement. Tumor of any size extending beyond the thyroid capsule to invade the subcutaneous soft tissues, the larynx, the trachea, the esophagus, or the recurrent laryngeal nerve pT4b: Very advanced disease. Tumor invades the prevertebral fascia or encases the carotid artery or mediastinal vessels Note: There is no category of carcinoma in situ (pTis) relative to carcinomas of thyroid gland. N Embryology the upper pair of parathyroid glands arises from the fourth branchial cleft and descends with the thyroid gland, usually at the cricothyroid junction. The lower pair arises from the third branchial cleft and descends with the thymus; the location of the lower parathyroids may be variable. Ectopic parathyroids may be found anywhere along the pathway of descent of the branchial pouches. The (lower) parathyroid glands have been described in the carotid sheath, anterior mediastinum, and intrathyroid. N Anatomy Grossly the parathyroid glands are yellow-brown, weighing 25 to 40 mg per gland. They each measure on average 6 mm in length, and from 3 to 4 mm in breadth, and usually present the appearance of flattened oval disks. N Histology Parathyroid glands are composed primarily of chief cells and fat with a thin fibrous capsule dividing the gland into lobules; the glands may have a pseudofollicle pattern resembling thyroid follicles. Head and Neck 495 N Blood Supply the arterial supply to the parathyroid glands gland originates from the superior and inferior parathyroid arteries, both of which usually arise from the inferior thyroid artery. Hyperparathyroidism is usually subdivided into primary, secondary, and tertiary hyperparathyroidism. Hyperparathyroidism results in elevated levels of plasma calcium by increasing the release of calcium and phosphate from bone matrix, increasing calcium reabsorption by the kidney, and increasing intestinal absorption of calcium. There are three types of hyperparathyroidism: primary, secondary, and tertiary, which are described below. Other familial conditions associated with all four gland hyperplasia include familial hyperparathyroidism-jaw tumor syndrome and familial isolated hyperparathyroidism. Epidemiology Primary hyperparathyroidism can occur at any age, but the great majority of cases occur over the age of 45 years. Clinical Primary hyperparathyroidism is most often detected incidentally by routine biochemical screening. Most patients are either asymptomatic or experience subtle and vague symptoms such as fatigue, depression, difficulty in concentration, and generalized weakness. Kidneys: Nephrolithiasis occurs in 15 to 20% of patients with primarily hyperparathyroidism. Gastrointestinal: Hypercalcemia associated symptoms include anorexia, nausea, vomiting, constipation, and peptic ulcer disease. Psychiatric and neurocognitive: Patients may have depressed mode, lethargy, emotional lability, and decreased cognitive function. Imaging G G G G G G G Sestamibi scan: 99mTc sestamibi localizes to the mitochondria of parathyroid cells, which are rich in mitochondria. Disadvantages include difficulty of localization of nonstandard locations and the potential of confusion with thyroid abnormalities, and interoperator variability. Selective venous sampling: the veins draining the parathyroid region can be sampled. Low serum phosphorus, increased 24-hour urinary calcium excretion, elevated serum 1,25-dihydroxyvitamin D may be seen. It is important to rule out familial hypocalciuric hypercalcemia because usually the course of this disease is benign and parathyroidectomy is not indicated. Past medical history should be carefully obtained as these patients are asymptomatic and have a history of elevated calcium levels since childhood. Secondary hyperparathyroidism should also be ruled out (either from a renal source or from decreased calcium absorption/intake or vitamin D deficiency).

Dynamic procedures erectile dysfunction 30 buy apcalis sx 20 mg with visa, nerve repair erectile dysfunction drug related purchase apcalis sx online, nerve substitution impotence effects on relationships purchase 20mg apcalis sx amex, and muscle transfer provide the best functional and cosmetic results and always should be the first choice in the rehabilitation of the paralyzed face. Static procedures are essential tools in the management of the eye and provide options for patients who are not candidates for dynamic rehabilitation. The goals of reanimation are facial symmetry, eye closure, oral competence, and voluntary movement. None of the described procedures can completely restore the paralyzed face to its normal function. Some synkinesis and residual weakness will persist, yet significant improvements in both function and appearance can be accomplished if the goals of reconstruction are kept in mind. Medical Otology and Neurotology: A Clinical Guide to Auditory and Vestibular Disorders. A skin graft retains an important role in oral cavity reconstruction and cutaneous facial defects. Complete immobilization of the graft in the early postoperative period is critical. Skin is the largest organ of the human body, representing 16% of the total body weight. Facial Plastic and Reconstructive Surgery 627 individual is termed an autogenous graft or autograft. Despite the development of sophisticated reconstructive methods utilized after ablative surgery, such as microvascular free flaps, much simpler approaches to reconstruction continue to be appropriate in many cases. Skin grafting in particular remains an excellent option for defects of the oral cavity, face, and scalp. N Anatomy and Physiology From superficial to deep, there are three layers of skin: the epidermis, the dermis, and the subcutaneous layer. The epidermis is further divided into the superficial stratum corneum (no nuclei) and the deeper basal layer. The dermis is further divided into the more superficial papillary dermis, and the deeper reticular dermis, which contains hair follicles and sebaceous glands. In the first stage, imbibition, the graft derives its nutrients from the underlying recipient bed. During the second stage, inosculation, preexisting blood vessels in both the graft and the recipient bed meet and form a network. Healing is completed by neovascularization, wherein new vessels form within the graft and grow into the underlying tissue. Skin grafts will "take" on most well-vascularized tissue, including granulation tissue, muscle, fat, perichondrium, and periosteum, and cancellous bone. Conversely, skin grafts will not survive on naked cortical bone or bare cartilage. N Indications Common settings for skin grafting in head and neck surgery include oral cavity defects after cancer resection, cutaneous defects of the face after lesion excision or trauma, closure of free flap donor sites (radial forearm, fibula, etc. N Operative Technique Split-Thickness Skin Graft G G the donor site of choice is the upper thigh (thick skin, relatively flat surface). Ensure the meticulous hemostasis of the recipient bed to prevent hematoma/loss of apposition. The skin graft is applied to the recipient site with the epidermis facing out then sutured into place with absorbable stitches, ensuring good apposition with the recipient bed. The edges of the graft are held with a skin hook, and the remainder of the graft is elevated from underlying fat using a knife or sharp scissors. G G G G G G Skin graft meshing: A skin graft may be meshed to provide coverage of a greater surface area at the recipient site, with expansion ratios generally ranging from 1:1 to 6:1. N Complications the major complication of skin grafting is partial or complete graft loss. Reasons for graft failure include hematoma, seroma, infection, and inadequate stabilization. Facial Plastic and Reconstructive Surgery 629 N Postoperative Care Feeding via a nasogastric feeding tube should be considered for oral cavity skin graft placement. A defect analysis should be done systematically to avoid untoward long-term results. Flap design must consider vectors of tension, resultant scars, and areas from which to recruit. Cutaneous defects can arise from a host of different causes, but skin cancer remains the most common etiology in the Caucasian population. Local facial flaps are widely used for defects that are too large for primary closure or second intention healing. They remain the workhorse for facial reconstruction and should be within the comfort level of all otolaryngologists. N Defect Evaluation When analyzing a cutaneous defect of the face, there is a series of steps that one should go through to help identify the optimal flap or, more importantly, 630 Handbook of OtolaryngologyHead and Neck Surgery Table 7. Examples of this would be the hairline, vermillion border of the lip, and nasal alar rim. These critical structures must remain undisturbed by scars as well as by flap tension. Third, evaluate the preexisting lines of the face and how are they oriented around the defect. The face is separated into distinct aesthetic units such as the forehead, nose, and cheek. When possible, it is best to place incisions along the margins of the aesthetic units and use flaps that lie within the same aesthetic unit as the defect. For every flap design, one should be able to anticipate the exact orientation of the final scars and attempt to design the flap in a way that best conforms to the third step, having the scars lie within or parallel to the preexisting lines. Moreover, one must anticipate the vectors of tension for each flap with respect to the landmarks noted in the first step. N Flap Nomenclature the different systems for classification of local flaps include tissue content, proximity of the flap, blood supply, and method of tissue transfer, the last two of which are the principal methods of nomenclature. The blood supply within a flap can be random (based on the rich dermal plexus of the face), can have an axial pattern (supplied by numerous larger caliber vessels in the dermis and subcutaneous layer that are arranged in an axial pattern along the flap), or can be pedicled (maintained by larger, named vessels). They create no distortion to the adjacent tissues, although a standing cutaneous deformity will often arise. They are further subclassified based on their vascular pedicle, be it a unilateral pedicle, a bipedicle, or subcutaneous pedicle (island flap). The remaining method of tissue transfer is the pivotal flap, in which the tissue transposition has a rotational element as well. A true rotation flap moves tissue along the circumference of a circle, around a single, fixed pivot point, such as a scalp rotation flap. A transposition flap involves mobilizing tissue over an incomplete bridge of skin. Interposition flaps are similar to transposition flaps but include elevation of the incomplete skin bridge to the site of the donor defect, such as a Z-plasty.

It is recommended that the verification team consists of external and independent qualified and certified maritime auditors erectile dysfunction doctor in bhopal cheap apcalis sx 20 mg line, familiar with cruise ship management erectile dysfunction treatment exercise cheap 20mg apcalis sx with visa, and health care professional(s) who are able to erectile dysfunction protocol ebook free download purchase apcalis sx 20mg on line assist in the professional judgement of the measures adopted. Protection of communities visited by the ship Crew, passengers, and residents of the visited ports should be protected during their interactions. To this end, information should be provided to the disembarking passengers about the local measures required at the visiting ports. Cruise operators should communicate with the Port State to ensure that the appropriate measures are implemented to avoid overcrowding and maintain appropriate physical distancing while passengers or crew disembark and re-board the ship. Any external provider who interacts with passengers such as tour guides should follow relevant cruise line protocols. If tenders or other means of transport are used to move passengers, physical distancing measures and protocols for their frequent cleaning and disinfection should be implemented in line with the procedures performed on board. If tendering services are offered by local companies, local health regulations need to be applied. In those cases, it should be checked whether these measures are equivalent of those taken on board the cruise ship. Cleaning and disinfection of any means of transport used, including tenders should be conducted between each use. In developing this Plan, it is essential that different authorities cooperate to ensure that all the perspectives are covered. Member State multi-disciplinary teams and contact points To restart operations of cruise ships it is recommended that different authorities within a Member State work together in close cooperation, namely: (a) Health authorities, in charge of public health and including occupational health and safety authorities; (b) Port State authorities, dealing mainly with the implementation of international legislation on the ships berthing in its ports, from the safety, security and environmental point of view and, in some instances, with other duties, like port reception facilities; (c) Port authorities/terminals, dealing with all the logistics related to port operations, both for cargo and passengers; (d) For contingency planning purposes: (if applicable) transport/airport, civil protection, home affairs and immigration authorities. For example, in some States, all the tasks might be concentrated in one authority while for others they can be distributed amongst different authorities. Irrespective of this, Member States are recommended to create multi-disciplinary teams covering all elements of this port plan to facilitate the coordination and communication with the cruise companies intending to visit their ports. For ease of reference, in this Guidance, the Member States authorities will be denominated "Port State", but this term should be understood as the conjunction of the different authorities: Health, Port State and Port Authorities, including terminal operators where applicable. It is recommended that each Port State, if not already the case, establishes and publishes contact points which can be used by cruise companies for direct communication with regard to the re-starting of operations in that State. Ideally, there should be a single contact point per Port State who could internally coordinate all the national procedures. Where this is not possible, the contacts should be provided with a brief description of the responsibilities that each contact has. For those States that already have such a plan, it is recommended, however, to review it to ensure that it covers all the elements necessary to safely restart cruise ship operations in their ports. It is also recommended that this Plan is agreed and shared amongst the different authorities involved (health, Port State and port authority/terminal operator) so that all perspectives are covered. If the cancellation concerns the actual conditions on board the ship, then the Port State should where possible propose alternative arrangements or mitigating measures before cancelling the call. The organisation and measures for re-embarkation of persons on board should also be covered. In addition, the conditions to allow disembarkation of persons who will return on board should be considered. The following points are suggested to be addressed: (a) Testing arrangements for possible and probable cases. This part of the plan should establish the procedures to approve such local plans where appropriate. If a pre-agreed ship call is cancelled, an alternative should be foreseen, where possible; the company could indicate whether the purchasing of. However, cruise ship companies are recommended to extend the prenotification period due to the current circumstances to allow for a better coordination with the port authorities. It must be reported by the master or any other person duly authorised by the operator of the ship to the competent authority designated by that Member State. The company should facilitate the application of health measures and provide all relevant public health information requested by the competent authority at the port. If it is considered that symptomatic possible or probable case/cases should not remain on board the ship, disembarkation should be conducted as quickly as possible. Member States can share this information with other Member States on a voluntary basis using the Incident Report type "Others. The Passenger and Crew Locator Forms of the crew/passengers disembarked44 should be made available to the Port State at any time, upon request. The information provided should be updated as soon as the relevant national, regional or local regulations and rules change. In addition, during the voyage planning stage, the Port State should confirm that the cruise ship call is accepted on that particular date and that the necessary conditions have been established. At the pre-arrival stage, once the required documentation provided prior to the ship call is verified, the Port State should confirm access to the port, either electronically. Port States which receive calls by cruise ships in their ports should have the capacity in the port of call itself or a nearby port to provide an appropriate public health emergency response, which is recorded in a continuously maintained public health emergency contingency plan. This plan should be made available to the cruise ship and should include information on contact tracing and management, and the quarantine of contact persons. Port States should develop procedures for disembarking infected passengers or crew who are to be transferred to hospital facilities. During the disembarkation of persons with possible, probable or confirmed infections, every effort should be made to minimise their exposure to other persons and to avoid environmental contamination. The contacts of these persons should be managed in accordance with the guidance in the Annex 1 (Management of contact persons). Any available medical record, Passenger or Crew Locator Forms or any other relevant information should be provided to the relevant health care personnel onshore. The Flag and Port States should support the cruise ship operator in making the necessary arrangements for repatriation in line with the Guidelines on protection of health, repatriation and travel arrangements for seafarers, passengers and other persons on board ships referred to above. Repatriation should be undertaken as quickly as possible while ensuring good medical infrastructure and transport connections for those persons being repatriated. The arrangements may include facilitating the docking of the ship, the disembarking of passengers, health screening and treatment. For high-exposure contacts, the quarantine arrangements should follow the recommendations made in Annex 1 (Management of Contact Persons). Access to medical care onshore for crew members in need should also be granted under any circumstance. That Directive lays down the obligations of the organiser, including to provide assistance to travellers in difficulty. A cruise organiser shall carry travellers to the port of disembarkation that is provided in the package travel contract. Package organisers are required to take out insolvency protection that shall cover repatriation of travellers, if carriage of passengers is included in the package travel contract. The first is related to mobility of people and the risk of transmission following arrival at the point of destination, and the second is the gathering of people at various venues such as airports, resorts and on modes of transport. In the particular situation where some Member States (especially those with small population) have decreased transmission to very low levels, the role of tourism and travel-related transmission may become significant due to the possibility of the virus being re-introduced at multiple sites, causing further spread. Travel advice (or travel recommendations) refers to official government advice that travellers should consider in order to minimise their risk of infection. Physical distancing Current scientific studies and articles52,53,54,55 confirm that, in general, the distance that large respiratory droplets can travel in the air is 1.

Occlusion · results in infarction of the splenium of the corpus callosum and the left visual cortex; visual input from the right visual cortex cannot reach the parietal language centers of the dominant hemisphere erectile dysfunction killing me cheap apcalis sx 20 mg otc. Jacksonian seizures (Jacksonian march) · are unilateral simple partial motor seizures that start with a tonic contraction of the fingers on one hand erectile dysfunction 9 code buy apcalis sx 20 mg line, the face on one side, or one foot, and progress to clonic contractions of the entire half of the body; they may progress to grand mal seizures. A lesion resulting in a nonfluent expressive aphasia would most likely be found in the (A) (B) (C) (D) (E) temporal lobe parietal lobe frontal lobe occipital lobe limbic lobe 1. A 55-year-old right-handed veteran received a small shrapnel wound in the head during the Vietnam War. Within 1 year of receiving his wound, the man complained of seizures and was treated with seizure medication. The medication was not effective, and a section of the anterior corpus callosum was performed successfully. A 70-year-old hypertensive man suddenly experiences numbness on the right side of his body. The lesion is most likely in the (A) (B) (C) (D) (E) right frontal lobe left parietal lobe right parietal lobe left temporal lobe right internal capsule 6. Alexia without agraphia and aphasia would most likely result from occlusion of the (A) (B) (C) (D) (E) left anterior cerebral artery right anterior cerebral artery left middle cerebral artery left posterior cerebral artery right posterior cerebral artery 8. Agraphia and dyscalculia would most likely result from a lesion in the (A) (B) (C) (D) (E) left frontal lobe left parietal lobe right occipital lobe left temporal lobe splenium of corpus callosum 3. Neurologic examination reveals pronator drift and mild hemiparesis on the right side. His speech is limited to expletives, he cannot write but does respond to questions by shaking his head, and he has lower facial weakness on the right side. The lesion is most likely in the (A) (B) (C) (D) (E) left frontal lobe right frontal lobe left parietal lobe right parietal lobe left temporal lobe 9. A patient is asked to bisect a horizontal line through the middle, to draw the face of a clock, and to copy a cross. The patient bisected the horizontal line to the left of the midline, placed all of the numerals of the clock on the right side, and did not complete the cross on the left side. Questions 16 to 20 Match the descriptions in items 16 to 20 with the appropriate lettered area shown in the figure. Lesion in this area results in paresthesias and numbness in the contralateral foot 18. Transection of corpus callosum results in the inability, when blindfolded, to identify verbally an object held in the left hand (dysnomia). Gait dystaxia may result from normal pressure hydrocephalus, which also involves dementia and incontinence. Transection of callosal fibers adjacent to the left premotor cortex produces right hemiparesis, motor (Broca) dysphasia, and sympathetic dyspraxia of the left, nonparalyzed, arm. The right hemiparesis points to a lesion on the left side involving the corticospinal tract. The cortical center for lateral conjugate gaze is located in area 8 of the frontal lobe. Destruction of this area results in turning of the head and eyes toward the side of the lesion. Stimulation of this area results in contralateral turning of the eyes and head; pronator drift and hemiparesis are frontal lobe signs. The Broca speech area is located in the posterior part of the inferior frontal gyrus (Brodmann areas 44 and 45). Nonfluent, expressive motor aphasia (Broca aphasia) results from a lesion in the posterior inferior frontal gyrus (areas 44 and 45) of the dominant frontal lobe. Broca speech area lies just anterior to the motor strip; both Broca speech area and the motor strip are irrigated by the superior division of the middle cerebral artery (prerolandic and rolandic arteries). Broca aphasia is frequently associated with sympathetic apraxia, an apraxia of the nonparalyzed left hand. Alexia without agraphia and aphasia results from occlusion of the left posterior cerebral artery, which supplies the left visual cortex and callosal fibers (within the splenium) from the right visual association cortex. Interruption of bilateral visual association fibers en route to the left angular gyrus results in alexia. Because the angular gyrus and Wernicke area are spared, the patient will not be agraphic or dysphasic. Lesions of the angular gyrus of the dominant hemisphere may result in Gerstmann syndrome, which consists of agraphia, dyscalculia, finger agnosia, and leftright confusion. The inability to draw a clock face or bisect a line through the middle is called construction apraxia. Lesions of the right (nondominant) parietal lobe result in construction apraxia, dressing apraxia, anosognosia, and sensory hemineglect. Broca speech area (areas 44 and 45) is found in the posterior part of the inferior frontal gyrus of the dominant hemisphere, directly anterior to the premotor and motor cortices. Wernicke speech area is located in the posterior part of the superior temporal gyrus (part of Brodmann area 22) of the dominant hemisphere. A lesion of the left postcentral gyrus results in a right astereognosis (tactile agnosia), the inability to identify objects by touch. Lesions of the superior parietal lobule result in contralateral astereognosis and in sensory neglect. The precentral gyrus (motor strip) gives rise to one-third of the pyramidal tract (corticospinal tract) fibers. A deep lesion of the angular gyrus could involve the visual radiation, resulting in a contralateral homonymous hemianopia. The dominant angular gyrus is the neurologic substrate of Gerstmann syndrome, which consists of rightleft confusion, finger agnosia, agraphia, and dyscalculia. The supplementary motor cortex (area 6) lies on the medial aspect of the hemisphere, just anterior to the paracentral lobule. A lesion in the posterior part of the paracentral lobule would result in loss of joint and position sense (astatognosia) and loss of tactile discrimination (astereognosis) in the contralateral foot. A lesion of the superior bank of the calcarine sulcus (cuneus) would result in a contralateral lower homonymous quadrantanopia. A lesion destroying both cunei would produce a lower homonymous altitudinal hemianopia. A lesion of the anterior part of the paracentral lobule results in a contralateral paresis of the foot muscles and in Babinski sign. Lesions of the prefrontal cortex may result in personality changes, with disorderly and inappropriate conduct and facetiousness and jocularity (witzelsucht). Lesions interrupt fibers that interconnect the dorsomedial nucleus and the prefrontal cortex. Apraxia · is the inability to perform motor activities in the presence of intact motor and sensory systems and normal comprehension. Ideomotor apraxia (ideokinetic apraxia) · is the loss of the ability to perform intransitive or imaginary gestures, resulting in the inability to perform complicated motor tasks.
