Oral lesions resembling aphthae occur in 2% or 3% of classic cases, but in 10% or more of those associated with hematologic malignancy. Pulmonary infiltrates and effusions are often seen on chest radiographs of such patients. Rarely, there may be cardiac, renal, hepatic, intestinal, and neurologic involvement. VermaP,etal: Idiopathic bullous eosinophilic cellulitis (Wells syndrome) responsive to topical tacrolimus and antihistamine combination. WinfieldH,etal: Eosinophilic cellulitis­like reaction to subcutaneous etanercept injection. Persistent cases, with new lesions erupting before the old lesions resolve, may continue for many years. The histologic hallmark of Sweet syndrome is a nodular and diffuse dermal infiltrate of neutrophils with karyorrhexis and massive papillary dermal edema. Leukocytoclastic vasculitis may be present focally, and this does not exclude a diagnosis of Sweet syndrome. Leukemic cells may be present in the infiltrate, and clonal restriction of neutrophils has even been seen in Sweet syndrome not associated with malignancy. Histologic variants described as histiocytic or lymphocytic Sweet syndrome have been reported. Occasionally, the main infiltrating cell resembles these cell types, but on immunohistochemical stains, they are found to be of myelogenous origin. Special investigations such as myeloperoxidase stains are positive and confirm Sweet syndrome as the diagnosis. Usually, myelodysplasia or frank leukemia is present or will manifest in the not-so-distant future. Other associated conditions include infections with Yersinia, toxoplasmosis, histoplasmosis, salmonellosis, tuberculosis, tonsillitis, and vulvovaginal infections. Cases have also been associated with peripheral ulcerative keratitis and Behçet syndrome. Hematologic malignancies or solid tumors are present in about 10% of reported cases. Sweet syndrome often presents early in the course of the cancer, when therapy is more efficacious. Associated malignancies are usually hemoproliferative and include leukemias (usually acute myelogenous), lymphomas, anemias, myelodysplastic syndrome, and polycythemia vera. Solid tumors are of any type but are most often genitourinary, breast (in women), or gastrointestinal (in men). Anemia is found in 93% of men and 71% of women with malignancy-associated Sweet syndrome. Solitary, bullous or ulcerative lesions are more frequently associated with malignancy. Pregnancy-associated Sweet syndrome typically presents in the first or second trimester with lesions on the head, neck, trunk, and less often on the upper extremities. The condition may resolve spontaneously or clear with topical or systemic corticosteroids. It may recur with subsequent pregnancies, but there seems to be no risk to the fetus. Many drug therapies have been associated with Sweet-like reactions in the skin, although the strongest association exists for granulocyte colony-stimulating factor and all-trans-retinoic acid. Oral contraceptives, radiation therapy fields, vaccines, bortezomib, gemcitabine, trimethoprim-sulfamethoxazole, and minocycline have been implicated. All-trans-retinoic acid causes terminal differentiation of some leukemic clones and is used to treat promyelocytic leukemia. Initially, these skin lesions may contain immature blasts, making it difficult to distinguish them from leukemia cutis. Induction of the skin lesions appears to be related to the desired pharmacologic effect of the medication. The two major criteria for the diagnosis of Sweet syndrome are the presence of red edematous plaques and a biopsy dem- Box7-1 Revised diagnostic criteria for diagnosis of Sweet syndrome* Majorcriteria 1. Abrupt onset of erythematous plaques or nodules, occasionally with vesicles, pustules, or bullae 2. Nodular and diffuse neutrophilic infiltration in the dermis with karyorrhexis and massive papillary dermal edema Minorcriteria 1. Preceded by a respiratory infection, gastrointestinal tract infection or vaccination, or associated with: · Inflammatory disease or infection · Myeloproliferative disorders or other malignancy · Pregnancy 2. Abnormal laboratory findings 3 of the following: · Erythrocyte sedimentation rate >20 mm/hr · C-reactive protein elevated · Leukocytosis >8000/mm3 · Left shift with >70% neutrophils 4. Excellent response to treatment with systemic corticosteroids *Both major criteria and two minor criteria are needed for diagnosis. Minor criteria include associated symptoms or conditions, laboratory findings, and response to therapy. Patients should have both major criteria and two of the four minor criteria for diagnosis (Box 7-1). Clinically, both diseases can have red plaques, and central vesiculation can occur. Bowel bypass syndrome has skin lesions that, on histologic examination, are identical to those of Sweet syndrome; fever and arthritis also accompany bowel bypass syndrome. In both, fever and arthritis may occur, along with leukocytosis with neutrophilia. A search for an underlying cause should be undertaken, especially in persons over age 50 and those with anemia, thrombocytopenia, or lesions that are bullous or necrotic. The standard treatment is systemic corticosteroids, with approximately 1 mg/kg/day of oral prednisone. Histologically, papillary dermal edema and a nodular and diffuse neutrophilic infiltrate with karyorrhexis are noted. RatzingerG,etal: Acute febrile neutrophilic dermatosis: a histopathologic study of 31 cases with review of literature. RequenaL,etal: Histiocytoid Sweet syndrome: a dermal infiltration of immature neutrophilic granulocytes. As the clinical appearance, tendency to relapse, response to treatment, and histologic features overlap with those of Sweet syndrome and pyoderma gangrenosum, this condition illustrates the close relationship of the various neutrophilic dermatoses. Neutrophilic dermatosis of the dorsal hands is best considered a localized variant of Sweet syndrome. Marshallsyndrome the rare Marshall syndrome is characterized by skin lesions resembling Sweet syndrome, which are followed by acquired cutis laxa. Small red papules expand to urticarial, targetoid plaques with hypopigmented centers. Histologic evaluation of the skin lesions usually shows a neutrophilic dermatosis virtually identical to Sweet syndrome. The lesions resolve with destruction of the elastic tissue at the site, producing soft, wrinkled, skin-colored protuberant plaques that can be pushed into the dermis. Elastic tissue in other organs may also be affected, especially the heart and lungs. DelPozoJ,etal: Neutrophilic dermatosis of the hands: presentation of eight cases and review of the literature. A primary lesion may not always be seen, and a substantial proportion of lesions appear at sites of trauma (pathergy). Satellite violaceous papules may appear just peripheral to the border of the ulcer and break down to fuse with the central ulcer. Fully developed lesions are painful ulcers with sharply marginated, undermined, blue to purple borders. These lesions have considerable overlap with what has been called "bullous Sweet syndrome" and are usually seen in patients with leukemia or polycythemia vera. The lesions are rarely painful, generally respond to relatively conservative treatments, and are usually not associated with underlying systemic disease. A peristomal variant occurs near such sites as painful erosions with violaceous, undermined borders. As the lesions evolve, they demonstrate suppurative inflammation in the dermis and subcutaneous fat. Massive dermal edema and epidermal neutrophilic abscesses are present at the violaceous, undermined border. Multiple infections, including mycobacteria, deep fungi, gummatous syphilis, synergistic gangrene, and amebiasis, must be excluded with cultures and special studies. Pyoderma gangrenosum may be misdiagnosed as a spider bite if there is only a solitary lesion on an extremity. Spider bites tend to evolve more rapidly and may be associated with other systemic symptoms or findings, such as disseminated intravascular coagulation. Thus, the initial workup of the patient includes studies necessary to ensure that the proper diagnosis is made, as well as to investigate possible associated diseases. The clinical lesions may be strikingly similar, evolving from small papulopustules to form ulcerations that do not heal. Histologic evaluation will often simply show suppurative dermatitis, since the injected or applied caustic substance may not be identifiable (urine, disinfectants, drain cleaner). Local treatment includes both proper wound care and medication to reduce inflammation; compresses or whirlpool baths are followed by the use of ointment or hydrophilic occlusive dressings. In solitary lesions or slowly progressive cases, application of potent topical corticosteroids, intralesional steroid injections, or tacrolimus may be beneficial, although pathergy may be seen at sites of injection. The absorption of tacrolimus in large or multiple wounds may lead to systemic blood levels. Systemic corticosteroids can be extremely effective, with initial doses in the range of 1 mg/kg. If corticosteroid reduction is not possible, a steroid-sparing agent may be added. Patients unresponsive to oral corticosteroids may benefit from pulse methylprednisolone, 1 mg/kg for 3­5 days, followed by 40­60 mg of prednisone tapering as the lesions heal. In general, when the disease is aggressive and corticosteroid therapy does not lead to rapid resolution, an immunosuppressive agent is added. The lesions often respond dramatically to these agents, including many that have not responded adequately to corticosteroids. Initial doses of cyclosporine of approximately 5 mg/kg/day are effective in most cases. Infliximab is given as intravenous infusions in doses of about 5 mg/ kg at weeks 0, 2, and 6 and then every 8 weeks. In very aggressive, rapidly progressive cases, consideration should be given to starting cyclosporine or infliximab treatment early to gain control of the disease. Sulfapyridine, sulfasalazine, salicylazosulfapyridine, dapsone, methotrexate, azathioprine, and minocycline generally are less helpful and may be useful adjuncts. Once the inflammatory component is controlled, the ulceration(s) will need to heal, so proper wound care is essential. Pathergy is rarely noted at the donor site when patients are receiving adequate immunosuppressive therapy. LiJ,etal: Treatment of pyoderma gangrenosum with mycophenolate mofetil as a steroid-sparing agent. Although more than half of these are autosomal dominant disorders inherited in patients with a family history of these syndromes or of deafness, amyloidosis or renal failure should be sought. Peritonitis, pleuritis, and vasculitis, including Henoch-Schönlein purpura, may also occur in these patients, who usually present before the teenage years. Febrile episodes of 1­3 weeks are accompanied by periorbital edema and a painful, distally migrating erythematous or urticarial-like plaques. Bone lesions, oral ulcers, and other findings are all reversed dramatically by anakinra. Two thirds of patients manifest various BelaniH,etal: Neutrophilic urticaria with systemic inflammation. KlukJ,etal: Chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature syndrome. Familial cold autoinflammatory syndrome is characterized by fever, cold urticaria, conjunctivitis, and arthralgia elicited by generalized exposure to cold. Patients with Muckle-Wells syndrome manifest most often in adolescence with acute febrile inflammatory episodes comprising abdominal pain, arthritis, urticaria, hearing loss, and multiorgan amyloidosis. Neonatal-onset multisystem inflammatory disease is characterized by fever, chronic meningitis, uveitis, sensorineural hearing loss, urticarial rash, and a deforming arthritis. Patients may also have dysmorphic facial appearance, clubbing of the fingers, mild mental retardation, and papilledema. Patients present in the newborn period with fever, swollen purplish red eyelids, red and purplish papules and plaques of the trunk, neck, and extremities, and lipodystrophy of the face, along with other systemic findings. Blau syndrome is an autosomal dominant disease with arthritis, uveitis, granulomatous inflammation, and camptodactyly. The dermatitis was polymorphic, but many patients had papules and plaques on the face, trunk, and extremities. This disease was dubbed "neutrophilic urticaria with systemic inflammation," which is differentiated from prior reports of neutrophilic urticaria. Clearing of the central region may occur, and lesions may coalesce, producing an annular or polycyclic pattern. When angioedema is not present, and fever, malaise, and joint/bone pain coexist, diagnostic consideration of an autoinflammatory condition is necessary, including many inherited syndromes, as previously described.

There are recurrent episodes of fever impotence or ed tadalafilo 20 mg buy low cost, arthralgias impotence curse purchase tadalafilo on line, and erythematous macules that may evolve into lesions with central hemorrhage. Acral hemorrhagic pustules, similar to those found in gonococcal sepsis, may be seen. Patients are generally young adults with fevers lasting 12 h interspersed with 1­4 days of well-being. Meningococcemia is caused by the fastidious gram-negative diplococcus Neisseria meningitidis. It has a polysaccharide capsule that is important in its virulence and serotyping. The human nasopharynx is the only known reservoir, with carriage rates in the general population estimated to be 5­10%. One dose of ciprofloxacin, 500 mg, is given after the initial course of antibiotics to clear nasal carriage. Rifampin, 10 mg/kg every 12 h for 2 days, is an alternative prophylactic therapy for children. A polyvalent vaccine is effective against groups A, C, Y, and W-135 and is recommended for high-risk groups. DuggalS,etal: Recent outbreak of meningococcal meningitis: a microbiological study with brief review of the literature. CazorlaC,etal: Fatal Vibrio vulnificus infection associated with eating raw oysters, New Caledonia. Skin lesions characteristically begin within 24­48 h of exposure, with localized tenderness followed by erythema, edema, and indurated plaques. Lesions occur in almost 90% of patients and are most common on the lower extremities. A purplish discoloration develops centrally and then undergoes necrosis, forming hemorrhagic bullae or ulcers. Other reported lesions include hemorrhagic bullae, pustules, petechiae, generalized macules or papules, and gangrene. If the skin is invaded primarily, septicemia may not develop, but the lesions may be progressive, and at times, limb amputation may be necessary. With septicemia, cellulitic lesions are the result of seeding of the subcutaneous tissue during bacteremia. Patients with advanced liver disease are at particular risk for developing septicemia. Other predisposing disorders are immunosuppression, alcoholism, adrenal insufficiency, diabetes, renal failure, male gender, and iron-overload states. The virulence of the bacterium is related to the production of exotoxin and various other factors. Treatment of this fulminant infection, which rapidly produces septic shock, includes antibiotics, surgical debridement, and appropriate resuscitative therapy. Chromobacteria have been shown to be common water and soil saprophytes of the southeastern United States and Australia. Several types of cutaneous lesions are caused by chromobacteria, ranging from fluctuating abscesses and local cellulitis to anthraxlike carbuncular lesions with lymphangitis and fatal septicemia. A gram-negative bacterium, Aeromonas hydrophilia, another typical soil and water saprophyte, may cause similar skin infections as C. MulhollandA,etal: A possible new cause of spa bath folliculitis: Aeromonas hydrophilia. Most cases of typhoid fever caused by Salmonella typhi are acquired by ingestion of contaminated food or water. Pets such as lizards, snakes, and turtles carry salmonellae, and acquisition of the organism in petting zoos has also been reported. Poultry and poultry products are the most important sources and are believed to be the cause in about half of common-source epidemics. After an incubation period of 1­2 weeks, there is usually an acute onset of fever, chills, headache, constipation, and bronchitis. They occur in crops, each group of 10­20 lesions lasting 3­4 days, the total duration of the exanthem being 2­3 weeks in untreated cases. A more extensive erythematous eruption occurring early in the course, erythema typhosum, is rarely reported, as are erythema nodosum, urticaria, and ulcers or subcutaneous abscesses. The diagnosis is confirmed by culturing the organism from blood, stool, skin, or bone marrow. If the organism is not grown on Shigella-Salmonella medium or is not analyzed correctly, S. Most cases are a result of person-to-person transmission; however, widespread epidemics have resulted from contaminated food and water. Small, blanchable, erythematous macules on the extremities, as well as petechial or morbilliform eruptions, may occur. Shigella and Salmonella are among the organisms reported to induce the postdysenteric form of Reiter syndrome. Occasionally, Helicobacter has been reported to cause postsurgical wound infections and sepsis in otherwise healthy individuals. The cellulitis may be multifocal and recurrent and may have a distinctive red-brown or copper color with minimal warmth. ItamuraT,etal: Helicobacter cinaedi cellulitis and bacteremia in immunocompetent hosts after orthopedic surgery. The disease begins insidiously with nasal catarrh, increased nasal secretion, and subsequent crusting. Gradually, there ensues a nodular or rather diffuse sclerotic enlargement of the nose, upper lip, palate, or neighboring structures. The nodules at first are small, hard, subepidermal, and freely movable, but they gradually fuse to form sclerotic plaques that adhere to the underlying parts. The lesions have a distinctive stony hardness, are insensitive, and are of a dusky purple or ivory color. In the more advanced stages of rhinoscleroma, the reactive growth produces extensive mutilation of the face and marked disfigurement. Complete obstruction of the nares, superficial erosions, and seropurulent exudation may occur. The rhinoscleroma bacillus is a gram-negative rod, short, nonmotile, round at the ends, always encapsulated in a gelatinous capsule, and measuring 2­3 µm. The disease occurs in both genders and is most common during the third and fourth decades of life. Although endemic in tropical countries in Africa and Central America, it is occasionally found in the United States. Rare familial cases have been reported, in which the condition may present in childhood. In the primary stage of nasal catarrh, the histologic picture is that of a mild, nonspecific inflammation. When proliferation and tumefaction develop, the granulomatous tumor consists largely of plasma cells, Mikulicz cells, an occasional hyaline degenerated plasma cell (Russell body), a few spindle cells, and fibrosis. The bacilli are found within foamy macrophages (Mikulicz cells) and are best visualized with the WarthinStarry silver stain. Rhinoscleroma has such distinctive features that its diagnosis should not be difficult. Clinically, rhinoscleroma can be confused with syphilitic gumma, sarcoid, leishmaniasis, frambesia (yaws), keloid, lepra, hypertrophic forms of tuberculosis, and rhinosporidiosis. However, it may respond well to the fluoroquinolones, although therapy should be prolonged, lasting at least 3 or 4 months, to limit the chance of relapse. DePontualL,etal: Rhinoscleroma: a French national retrospective study of epidemiological and clinical features. The open sites become inflamed, lymphangitis and fever develop, and axillary lymph nodes become enlarged. Pasteurella multocida is a small, nonmotile, gram-negative, bipolar-staining bacterium. It is known to be part of the normal oral and nasal flora of cats and dogs, but it may also be an animal pathogen. The most common type of human infection follows injuries from animal bites, principally cat and dog bites, but also cat scratches. After animal trauma, erythema, swelling, pain, and tenderness develop within a few hours of the bite, with a gray-colored serous or sanguinopurulent drainage from the puncture wounds. There may or may not be regional lymphadenopathy or evidence of systemic toxicity such as chills and fever. Septicemia may follow the local infection in rare cases, and tenosynovitis and osteomyelitis appear with some frequency. Fever, nausea, and vomiting occur abruptly within 1­3 days, and the eschar develops soon thereafter. Disseminated intravascular coagulation and extensive dry gangrene may complicate the course. Sepsis after a dog bite is another hazard faced by splenectomized patients, in addition to their particular problems with pneumococcus, Haemophilus influenzae group B, babesiosis, Neisseria meningitidis, and group A streptococcus. Laboratory personnel need to be aware of the clinical suspicion of infection with this organism. Neisseria species and Bergeyella zoohelcum are other oral and nasal commensals in dogs; thus, most reports of human disease follow animal bites. Eikenella corrodens, a facultative gramnegative bacillus, is a normal inhabitant of the human mouth. Capnocytophaga canimorsus is a gram-negative rod that is part of the normal oral flora of dogs and cats. The distinctive skin lesion is an inflammatory papule or vesicle that arises at the site of 271 Glanders 14 Bacterial Infections inoculation, rapidly becomes nodular, pustular, and ulcerative, and forms an irregular excavation with undermined edges and a base covered with a purulent and sanguineous exudate. In a few days or weeks, other nodules (called "farcy buds") develop along the lymphatics in the adjacent skin or subcutaneous tissues and subsequently break down. In the acute form, the skin involvement may be severe and accompanied by extreme diarrhea. Patients with the chronic form have few skin lesions and milder constitutional symptoms, but repeated cycles of healing and breakdown of nodules may occur for weeks. After accidental inhalation, catarrhal symptoms are first present, and there may be epistaxis or a mucoid nasal discharge. The diagnosis is established by finding the gram-negative organism in this discharge or in the skin ulcers and should be confirmed by serum agglutination. This organism has been fatal to many laboratory workers, and exposure in this setting is increasing, with B. Treatment is chiefly by immediate surgical excision of the inoculated lesions and antibiotics. It is present mostly in subSaharan Africa and presents as a suppurative granulomatous inflammation of the skin and lymphatics. Several species cause human diseases, including Bartonella henselae (cat-scratch disease and bacillary angiomatosis), B. Unique to this genus is the ability to cause vascular proliferation, as seen in bacillary angiomatosis and verruga peruana. The bartonellae in affected tissue stain poorly with tissue Gram staining and are usually identified in tissue using modified silver stains such as Warthin-Starry. They are difficult to culture, making tissue identification of characteristic bacilli an important diagnostic test. About 22,000 cases are reported annually in the United States, with 60­90% occurring in children and young adults. Cat-scratch disease is the most frequent cause of chronic lymphadenopathy in children and young adults. The infectious agent is transmitted from cat to cat by fleas and from cats to humans by cat scratches or bites. In geographic areas where cat fleas are present, about 40% of cats are asymptomatically bacteremic with this organism. An immunocompromised patient with typical cat-scratch disease caused by Bartonella grahamii has been reported. The primary skin lesion appears within 3­5 days after the cat scratch and may last for several weeks. The disease has an acute pulmonary and septicemic form in which multiple miliary abscesses in the viscera occur, resulting in rapid death. Less often, it runs a chronic course, with subcutaneous abscesses and multiple sinuses of the soft tissues. Its clinical characteristics are similar to glanders, disseminated fungal infections, and tuberculosis. Melioidosis is endemic in India, Southeast Asia, and northern Australia and should be suspected in military personnel and travelers who have characteristic symptoms of a febrile illness and have been in that region. Diagnosis is made from the recovery of the bacillus from the skin lesions or sputum and by serologic tests. The majority of chronic cutaneous infections respond well to oral treatment alone. Lymphadenopathy, the hallmark of the disease, appears 1 or 2 weeks after the primary lesions or 10­50 days (average 17) after inoculation. Because most inoculations occur on the upper extremities, epitrochlear and axillary lymphadenopathy is most common (50%), followed by cervical (25%) or inguinal (18%). Generalized lymphadenopathy does not occur, but systemic symptoms such as fever, malaise, and anorexia may be present.

Cases associated with terbinafine may be related to apoptosis induced by the drug erectile dysfunction doctors charlotte cheap tadalafilo 10 mg on line. Cytoid bodies are often seen erectile dysfunction vacuum pumps australia order tadalafilo toronto, although continuous granular staining with IgG how is erectile dysfunction causes tadalafilo 5 mg visa, IgM erectile dysfunction pills australia order tadalafilo 2.5 mg overnight delivery, and IgA may be seen what causes erectile dysfunction treatment buy tadalafilo uk. X-ray studies with barium swallow may show weak pharyngeal muscles and a collection of barium in the piriform sinuses and valleculae. Aldosteronism, with adenoma of adrenal glands and hypokalemia, may also cause puffy heliotrope eyelids and face. There is a bimodal peak, the smaller one seen in children and the larger peak in adults age 40­65. Etanercept has also been used, but some studies have found little improvement or flares of muscle disease. Onset of calcinosis is associated with delays in diagnosis and treatment, as well as longer disease duration. The skin lesions may respond to systemic therapy; however, response is unpredictable, and skin disease may persist despite involution of the myositis. Non­life-threatening cutaneous reactions occur in approximately one third of patients, and up to one half of those who react to hydroxychloroquine will also react to chloroquine. In pregnant patients who require treatment, evidence supports the use of topical corticosteroids and topical calcineurin inhibitors. Published evidence also suggests that systemic corticosteroids, hydroxychloroquine, and azathioprine may be used in pregnancy when necessary. Cutaneous types may be categorized as morphea (localized, generalized, profunda, atrophic, and pansclerotic types) or linear scleroderma (with or without melorheostosis or hemiatrophy). Independent risk factors include failure to induce clinical remission, white blood cell count above 10 000/mm3, temperature greater than 38°C (100. Early aggressive therapy in juvenile cases is associated with a lower incidence of disabling calcinosis cutis. Cutaneoustypes Localizedmorphea the morphea form of scleroderma is twice as common in women as men and occurs in childhood as well as adult life. It presents most often as macules or plaques a few centimeters in diameter, but also may occur as bands or in guttate lesions or nodules. The margins of the areas are generally surrounded by a lilac border or by telangiectases. Within the patch, skin elasticity is lost, and when it is picked up between the thumb and index finger, it feels rigid. The follicular orifices may be unusually prominent, leading to a condition that resembles pigskin. In guttate morphea, multiple small, chalk-white, flat or slightly depressed macules occur over the chest, neck, shoulders, or upper back. Panscleroticmorphea Pansclerotic morphea manifests as sclerosis of the dermis, panniculus, fascia, muscle, and at times the bone. Morpheaprofunda Morphea profunda involves deep subcutaneous tissue, including fascia. There is clinical overlap with eosinophilic fasciitis, eosinophilia myalgia syndrome, and the Spanish toxic oil syndrome. The latter two conditions were related to contaminants found in batches of tryptophan or cooking oil. Unlike eosinophilic fasciitis, morphea profunda shows little response to corticosteroids and tends to run a more chronic debilitating course. Linearscleroderma these linear lesions may extend the length of the arm or leg and may follow lines of Blaschko. Lesions may also occur parasagittally on the frontal scalp and extend partly down the forehead (en coup de sabre;. The Parry-Romberg syndrome, which manifests as progressive hemifacial atrophy, epilepsy, exophthalmos, and alopecia, may be a form of linear scleroderma. When the lower extremity is involved, there may be associated spina bifida, faulty limb development, hemiatrophy, or flexion contractures. Melorheostosis, seen on radiographs as a dense, linear cortical hyperostosis, may occur. Physical therapy of the involved limb is of paramount importance to prevent contractures and frozen joints. Generalizedmorphea Widespread involvement by indurated plaques with pigmentary change characterizes generalized morphea. Patients may lose their wrinkles as a result of the firmness and contraction of skin. Spontaneous involution is less common with generalized morphea than with localized lesions. The disease consists of brownish gray, oval, round or irregular, smooth atrophic lesions depressed below the level of the skin, with a welldemarcated, sharply sloping border. Some of the appearance of depression is an optical illusion related to the color change. Linear atrophoderma of Moulin is a related condition that follows lines of Blaschko. Biopsies of atrophoderma demonstrate a reduction in the thickness of the dermal connective tissue. Because the changes may be subtle, a biopsy should include normalappearing skin so that a comparison may be made. Patients may present with sclerodactyly, severe heartburn, or telangiectatic mats. The mats tend to have a smooth outline, in contrast to the mats of the Osler-Weber-Rendu syndrome, which tend to exhibit an irregular outline with more radiating vessels. Digital pitting scars of the fingertips or loss of substance of the distal finger pad 3. Bilateral basilar pulmonary fibrosis Localized forms of scleroderma must be excluded. These criteria have been shown to be 97% sensitive and 98% specific for the diagnosis. Skin changes: tightness, thickening, and nonpitting induration, sclerodactyly, proximal scleroderma; changes proximal to the metacarpophalangeal or metatarsophalangeal joints and affecting other parts of the extremities, face, neck, or trunk (thorax or abdomen), digital pitting, loss of substance from the finger pad, bilateral firm but pitting finger or hand edema, abnormal skin pigmentation (often "pepper and salt"). The changes are usually bilateral and symmetric and almost always include sclerodactyly. Raynaud phenomenon: at least two-phase color change in fingers and often toes consisting of pallor, cyanosis, and reactive hyperemia 3. Visceral manifestations: bibasilar pulmonary fibrosis not attributable to primary lung disease, lower (distal) esophageal dysphagia, lower (distal) esophageal dysmotility, colonic sacculations Skin findings In the earlier phases of scleroderma, affected areas are erythematous and swollen. The skin becomes smooth, yellowish, and firm and shrinks so that the underlying structures are bound down. The earliest changes often occur insidiously on the face and hands, and in more advanced stages, these parts become "hidebound," so the face is expressionless, the mouth is constricted. The facial skin appears drawn, stretched, and taut, with loss of lines of expression. The lips are thin, contracted, and radially furrowed; the nose appears sharp and pinched; and the chin may be puckered. The "neck sign" is described as a ridging and tightening of the neck on extension, occurring in 90% of patients with scleroderma. The disease may remain localized to the hands and feet for long periods (acrosclerosis). Women are affected three times more often than men, with peak age of onset between the third and fifth decades. There is limitation of motion as a result of skin tautness, followed by ankylosis and severe contractual deformities. There may be resorption and shortening of the phalanges and narrowing of the joint spaces. Osteoporosis and sclerosis of the bones of the hands and feet may occur, as well as decalcification of the vault of the skull. Raynaud phenomenon occurs less often, whereas cardiac wall involvement is more common and is responsible for half of deaths. Renal disease accounts for some early mortality, but pulmonary disease remains the major cause of death. The presence of many telangiectases is strongly associated with the presence of pulmonary vascular disease. In the "round finger-pad sign," the fingers lose their normal peaked contour and appear as rounded hemispheres when viewed from the side. Trophic ulcerations and gangrene may occur on the tips of the fingers and knuckles, which may be painful or insensitive. Dilated nailfold capillary loops are present in 75% of systemic scleroderma patients. Nailfold capillary hemorrhage in two or more fingers is highly specific for scleroderma and correlates with the anticentromere antibody. Keloidlike nodules may develop on the extremities or the chest, and there may be a widespread diffuse calcification of the skin, as shown by radiographs. A diffuse involvement of the chest may lead to a cuirasslike restraint of respiration. Late in the course of the disorder, hyperpigmented or depigmented spots or a diffuse bronzing may be present. The most characteristic pigmentary change is a loss of pigment in a large patch with perifollicular pigment retention within it. The affected areas become hairless, and atrophy is often associated with telangiectasia. Bullae and ulcerations may develop, especially on the distal parts of the extremities. As noted, several of these antibodies identify specific clinical subsets of patients. The antinucleolar pattern is considered most specific for scleroderma, and when present as the only pattern, it is highly specific for scleroderma. Patients with antibodies to Scl-70 tend to have diffuse truncal involvement, pulmonary fibrosis, and digital pitted scars, but a lower incidence of renal disease. These patients are fairly homogeneous and the term is not synonymous with connective tissue overlap. Anti-Rpp25 chemiluminescence and anti-Th/To by immunoprecipitation correlate with limited cutaneous and internal involvement. Pulmonary fibrosis with arterial hypoxia, dyspnea, and productive cough may be present. Progressive nonspecific interstitial fibrosis, with bronchiectasis and cyst formation, is the most frequent pathologic change. Pulmonary hypertension and right-sided heart failure are ominous signs, occurring in 5­10% of patients. The cardiac involvement produces dyspnea and other symptoms of congestive heart failure. In early esophageal involvement, a barium swallow in the usual upright position may be reported as normal. If the patient is supine, however, barium will often be seen to pool in the flaccid esophagus. The stomach may be dilated and atonic, resulting in delayed 169 Scleroderma 8 Connective Tissue Diseases emptying time. Involvement of the small intestine may cause extreme dilation of the duodenum and jejunum, producing a characteristic radiographic picture of persistently dilated intestinal loops long after the barium has passed through. Histology Systemic and localized forms of scleroderma show similar histologic changes, although lymphoid infiltrates tend to be heavier in the acute phase of morphea. In the acute phase, there is a perivascular lymphocytic infiltrate with plasma cells that is heaviest at the junction of the dermis and subcutaneous fat. Collagen bundles become hyalinized, and the space between adjacent bundles is lost. As the dermis replaces the subcutaneous tissue, eccrine glands appear to be in the midportion of the thickened dermis. The subcutaneous fat is quantitatively reduced, and adventitial fat (fat that normally surrounds adnexal structures on trunk) is lost. Elastic fibers in the reticular dermis may be prominent and stain bright red, and the papillary dermis may appear pale and edematous. Pilosebaceous units are absent, and eccrine glands and ducts are compressed by surrounding collagen. The "stiff skin syndrome," also known as congenital fascial dystrophy, is characterized by stony-hard induration of the skin and deeper tissues of the buttocks, thighs, and legs, with joint limitation and limb contractures. Scleroderma-like symptoms may be the presenting features of multiple myeloma and amyloidosis. IgG4-related disease presents with soft tissue sclerosis, elevated serum IgG4, and increased IgG4-positive plasma cells in a variety of tissues. Pathogenesis the pathogenesis of scleroderma and morphea involves vascular damage, autoimmune mechanisms, and possibly microchimerism resulting in alloimmune graft-versus-host reactions. Both anticardiolipin and anti­2-glycoprotein I antibodies appear to play roles in pathogenesis. Borrelia afzelii and Borrelia garinii are related to the development of morphealike lesions in some cases. In women, there is an association with teaching and working in the textile industry. Th2 cells are less potent than T-helper 1 (Th1) cells in inhibiting collagen production by normal fibroblasts, and fibroblasts from involved skin are resistant to inhibition.

Some experience indicates that fexofenadine is less likely to work at higher-than-standard dosages erectile dysfunction trials discount tadalafilo 2.5 mg online, so this is not escalated if there is no response at standard dosage erectile dysfunction drugs levitra proven 20 mg tadalafilo. Cetirizine and some of the other second-generation antihistamines can cause drowsiness in some individuals erectile dysfunction doctor type buy discount tadalafilo 5 mg line, particularly in higher doses or when combined with other antihistamines impotence purchase tadalafilo 2.5 mg on line. Although some add an H2 blocker such as ranitidine as well erectile dysfunction drugs in philippines generic 2.5 mg tadalafilo with mastercard, evidence is conflicting on whether this is an effective strategy. Ranitidine should not be used alone for treatment of urticaria because it may interfere with feedback inhibition of histamine release. Also, doxepin, a tricyclic antidepressant with potent H1 antihistaminic activity, may be useful, but evidence is weak. Doxepin is frequently dosed at bedtime, so much of the drowsiness and dry mouth are gone by morning. The same is true for first-generation antihistamines; if any is added to the previous second-generation strategy, it should only be used at night. If it is necessary to consider other therapies, the following guidance is offered. Cyclosporine and prednisone are often effective but the potential for side effects limit their clinical utility. Also, because the prognosis is that at least 20% of patients, and up to 50% in some studies, will continue to have chronic spontaneous urticaria after 5 years, the role of these two agents is limited. Dapsone, colchicine, and sulfasalazine may be most useful if the biopsy shows a preponderance of neutrophils, and they may be added to antihistamine treatment if some response to the latter has been obtained. Hydroxychloroquine, leukotriene receptor antagonists such as montelukast, and even phototherapy may have some benefit in individual patients. Data are accumulating that omalizumab, a recombinant humanized monoclonal antibody that binds to free IgE, is effective in many patients with chronic spontaneous urticaria in doses of 150­300 mg every 4 weeks. Topical corticosteroids, topical antihistamines, and topical anesthetics have no role in the management of chronic urticaria. For local treatment, tepid or cold tub baths or showers may be freely advocated if cold is not a trigger. In about one third of patients with chronic idiopathic urticaria, autoantibodies bind to high-affinity IgE receptors. Unfortunately, testing for this condition is not well standardized, has false-positive results, and is impractical. The first is considered a deep form of urticaria and may be observed as solitary or multiple sites of angioedema alone or in combination with urticaria. The action of histamine creates vasomotor lability, and pruritus may be a significant feature. Patients may experience local swelling in subcutaneous tissues (face, hands, arms, legs, genitals, buttocks); abdominal organs (stomach, intestines, bladder), mimicking surgical emergencies; and the upper airway (larynx), which can be life threatening. The factors that trigger attacks are minor trauma, surgery, sudden changes of temperature, or sudden emotional stress. Type I is characterized by low antigenic and functional plasma levels of a normal C1 esterase Angioedema Angioedema is an acute, evanescent, circumscribed edema that usually affects the most distensible tissues, such as the eyelids, lips. C4 will be low (<40% of normal) as a result of continuous activation and consumption. Attenuated androgens, C1 inhibitors, and in some cases antifibrinolytics are useful for long-term prophylaxis. Episodic angioedema or isolated facial edema may occur with fever, weight gain, eosinophilia, and elevated eosinophil major basic protein (Gleich syndrome). Anaphylaxis Anaphylaxis is an acute and often life-threatening immunologic reaction, frequently heralded by scalp pruritus, diffuse erythema, urticaria, or angioedema. Bronchospasm, laryngeal edema, hyperperistalsis, hypotension, and cardiac arrhythmia may occur. Antibiotics (especially penicillins), other drugs, and radiographic contrast agents are the most common causes of serious anaphylactic reactions. Hymenoptera stings are the next most frequent cause, followed by ingestion of crustaceans and other food allergens. Atopic dermatitis is frequently associated with anaphylaxis, regardless of origin. Causative agents can be identified in up to two thirds of cases, and recurrent attacks are the rule. Exercise-induced anaphylaxis often depends on priming by prior ingestion of a specific food, or food in general, and aspirin may be an additional exacerbating factor. KhakooG,etal: Clinical features and natural history of physical urticaria in children. MaurerM,etal: Revisions to the international guideline on the diagnosis and therapy of chronic urticaria. PresslerA,etal: Failure of omalizumab and successful control with ketotifen in a patient with vibratory angio-oedema. Acquired angioedema I is a rare disorder associated with lymphoproliferative disease. These associations include lymphomas (usually B cell), chronic lymphocytic leukemia, monoclonal gammopathy, myeloma, myelofibrosis, Waldenström macroglobulinemia, and breast carcinoma. Part of the management of this condition is to treat the causative associated condition. Antifibrinolytic agents, such as aminocaproic acid or tranexamic acid, may be beneficial and are more effective than antiandrogen therapy. Basic to all these is a complex array of autoimmune responses that target or affect collagen or ground substance. Most often, the thorax and upper extremities are affected as well as the head and neck. The scalp may become quite bald with striking patterns of hyperpigmentation and depigmentation. Lesions begin as dull-red macules or indurated plaques that develop an adherent scale, then evolve with atrophy, scarring, and pigment changes. In darker-skinned individuals, lesions typically demonstrate areas of both hyperpigmentation and depigmentation. In lighter-skinned patients, the plaques may appear gray or have minimal pigment alteration. The hyperkeratosis characteristically extends into patulous follicles, producing carpet tack like spines on the undersurface of the scale. In most other respects, the clinical presentation and course are similar to those in adults. Histology the epidermis may demonstrate effacement of the rete ridge pattern or irregular acanthosis. Compact hyperkeratosis without parakeratosis is characteristic, and follicular plugging is typically prominent. Hydropic degeneration of the basal layer of the epidermis and follicular epithelium results in pigmentary incontinence. A patchy perivascular and periadnexal lymphoid inflammatory infiltrate occurs in the superficial and deep dermis. The infiltrate characteristically surrounds vessels, follicles, and the eccrine coil. Increased mucin is often present and may be visible as deposition of a blue to amphophilic substance between collagen bundles, or merely as a widening of the space between the bundles. Acute lesions show only patchy lymphoid inflammation and vacuolar interface dermatitis. Chronic, inactive lesions show atrophy, with postinflammatory pigmentation and scarring throughout the dermis. At this stage, the inflammatory infiltrate is sparse to Localized discoid lupus erythematosus Discoid lesions are usually localized above the neck. Favored sites are the scalp, bridge of the nose, malar areas, lower lip, and ears. On the scalp, most lesions begin as erythematous patches or plaques that evolve into white, often depressed, hairless patches. Perifollicular erythema and the presence of easily extractable anagen hairs are signs of active disease and are helpful in monitoring the response to therapy. Scarred areas may appear completely smooth or may demonstrate dilated follicular openings in the few remaining follicles. Seborrheic dermatitis does not show atrophy, alopecia, or dilated follicles and has greasy, yellowish scale without follicular plugs. In these cases, the presence of continuous granular immunoglobulin in addition to cytoid bodies is a helpful distinguishing feature. It may be necessary to differentiate syphilis and sarcoid by biopsy and serologic testing. The lesions are usually large, atrophic, hypopigmented, red or pink patches and plaques. Pigment abnormalities become prominent over time, and fine telangiectasia and scaling are usually present. Prominent palmoplantar involvement is characteristic and tends to be the most troublesome feature for these patients. Response to treatment is poor, although potent topical corticosteroids, dapsone, thalidomide, or isotretinoin may be effective. Histologically, the lesions demonstrate a patchy superficial and deep perivascular and periadnexal lymphoid infiltrate that frequently affects the eccrine coil. Usually, the overlying skin is normal, but overlying discoid or tumid lesions may occur. Histologic sections demonstrate lymphoid nodules in the subcutaneous septa, necrosis of the fat lobule, and fibrinoid or hyaline degeneration of the remaining lipocytes. The overlying epidermis may show basal liquefaction and follicular plugging or may be normal. Dermal lymphoid nodules or vertical columns of lymphoid cells may be seen in fibrous tract remnants. Dermal mucin may be prominent, and dermal collagen hyalinization (resembling that seen in morphea) may be present. The most important entity to consider in the differential diagnosis is subcutaneous panniculitis­like lymphoma. Important clues include the presence of lipocytes, rimmed by atypical lymphocytes with nuclear molding, and the presence of constitutional symptoms. Erythrophagocytosis may be present focally, and T-cell clonality can usually be demonstrated. Lesions are scaly and evolve as polycyclic annular lesions or psoriasiform plaques. The scale is thin and easily detached, and telangiectasia or dyspigmentation may be present. Follicles are not involved; the lesions tend to be transient or migratory, and there is no scarring. Lesions tend to occur on sun-exposed surfaces of the face and neck, the V portion of the chest and back. Skin involvement occurs in 80% of cases and is often helpful in arriving at a diagnosis. Neurologic disorders (seizures or psychosis in the absence of other known causes) 8. A dustlike particulate deposition of IgG in epidermal nuclei of Ro-positive patients may be present and is a helpful diagnostic finding. These infants have no skin lesions at birth, but develop them during the first few weeks of life. Telangiectasia or dermal mucinosis in an acral papular pattern may be the predominant findings in some cases. Telangiectatic macules or angiomatous papules may be found in sun-protected sites such as the diaper area, may occur independently of active lupus skin lesions, and may be persistent. The skin lesions usually resolve spontaneously by 6 months of age, and usually heal without significant scarring, although atrophy and telangiectatic mats may persist. Half the mothers are asymptomatic at delivery, although many will subsequently develop arthralgia, Sjögren syndrome, or other mild systemic findings. Although the skin lesions are transient, half the patients have an associated isolated congenital heart block, usually third degree, which is permanent. In children with cutaneous involvement, thrombocytopenia and hepatic disease may occur as frequently as cardiac disease. Biopsies at all sites show interface dermatitis and a scant perivascular lymphoid infiltrate. Heterozygous deficiency of either complement component C4A or C4B has a frequency of approximately 20% in white populations. In bullous lesions, there is a subepidermal bulla or superficial dermal edema containing neutrophils. Neutrophils are found in or below the lamina densa on immunofluorescent electron microscopy. The recognition of this subset as distinct is made clear by its often dramatic therapeutic response to dapsone. Capillary loops in the Osler-WeberRendu syndrome demonstrate ectasia of half the capillary loop. The palms, soles, elbows, knees, or buttocks may become persistently erythematous or purplish, sometimes with overlying scale. Leg ulcers, typically deeply punched out and with very little inflammation, may be seen on the pretibial or malleolar areas. Many of these patients present with a livedoid pattern, and many have an antiphospholipid antibody. Sneddon syndrome is composed of livedo reticularis and strokes related to a hyalinizing vasculopathy.

Centrifugal abdominal lipodystrophy Most cases of "lipodystrophia centrifugalis abdominalis infantilis erectile dysfunction icd 9 code wiki cheap tadalafilo 20 mg on line," as described by Imamura et al erectile dysfunction blogs forums 2.5 mg tadalafilo purchase visa. It is characterized by depression of the skin caused by loss of fat in the groin (80% of patients) or axilla (20%) hard pills erectile dysfunction buy 20 mg tadalafilo fast delivery. The atrophic area slowly enlarges centrifugally for 3­8 years in most patients erectile dysfunction caused by prostate removal tadalafilo 20 mg purchase without a prescription, often stopping with the onset of puberty erectile dysfunction drugs thailand 5 mg tadalafilo order free shipping. In 80%, the depressed area was surrounded by a discrete, erythematous border with scale. One third of patients have multiple lesions, and regional lymph nodes are enlarged in 65%. When the lesion stops expanding, the erythematous rim and lymphadenopathy disappear. Lipoatrophia annularis (Ferreira-Marques syndrome) Lipoatrophia annularis primarily affects women and usually involves the upper extremity. The lipoatrophy may be preceded by erythema, a bracelet-shaped swelling, and tenderness of the entire extremity. This is followed by loss of subcutaneous fat, with the arm divided into two parts by a depressed, atrophic, braceletlike constriction. In acromegaly, changes in the soft tissues and bones form a characteristic syndrome. In association with the well-known changes in the facial features caused by gigantic hypertrophy of the chin, nose, and supraorbital ridges, there is thickening, reddening, and wrinkling of the forehead and exaggeration of the nasolabial grooves. There is diffuse hypertrophy of the skin, which is at least partly caused by deposition of colloidal iron-positive material in the papillae and reticular dermis. This increased skin thickness can be demonstrated in lateral radiographs of the heel, with reversal toward normal after treatment. The viscera also enlarge and patients may develop a variety of rheumatologic, cardiovascular, metabolic, and respiratory complications. Acromegaloid facial appearance syndrome is an inherited condition in which only the facial changes are present, and no abnormality of growth hormone exists. Pseudoacromegaly is an acquired condition that may be seen in patients with severe insulin-resistant diabetes, which appears to be a fibroblast defect, or in patients receiving long-term minoxidil. The currently preferred treatment is a transsphenoidal microsurgical excision of the tumor. Medical therapy may be used as a primary treatment for those unsuitable for surgery, as a preoperative treatment, or as secondary therapy after failed surgery. After 18­24 months of therapy, 50% of patients will completely normalize, with the exception of hyperhidrosis, which persists in most patients. The growth hormone receptor antagonist pegvisomant is another medical option to normalize growth hormone secretion. Ribeiro-OliveiraA,etal: the changing face of acromegaly: advances in diagnosis and treatment. The most prominent features of Cushing syndrome include central obesity, affecting the face, neck, trunk, and especially the abdomen, but sparing the limbs. There is classically deposition of fat over the upper back, referred to as a buffalo hump. The striking and distressing skin changes include hypertrichosis, dryness, acne, susceptibility to superficial dermatophyte and Pityrosporon infections, a plethora over the cheeks, anterior neck, and V of the chest, and the characteristic purplish, atrophic striae that may involve the abdomen. Skin fragility and thinning occur such that easy bruising and a cigarette paper­type wrinkling are present. The thinning of the skin can be demonstrated and measured in lateral radiographs of the heels. Women, who are affected four times more frequently than men in noniatrogenic cases, develop facial lanugo hypertrichosis, 491 24 Endocrine Diseases with thinning of the scalp hair. Occasionally, there may be livedo reticularis, purpura, ecchymosis, or brownish pigmentation. Opportunistic fungal infections occur, either with organisms that are not normally pathogenic or as uncommon presentations of common infections. Patients with Cushing syndrome usually have hypertension and marked generalized arteriosclerosis, with progressive weakness, prostration, and pains in the back, limbs, and abdomen; kyphosis of the dorsal spine also occurs, accentuating the buffalo hump appearance. In 20% of patients, a disturbance in carbohydrate metabolism develops, with hyperglycemia, glycosuria, and diabetes mellitus. These varied symptoms indicate a marked and widespread disturbance caused by the hyperactive adrenal cortex. Iatrogenic Cushing syndrome is usually secondary to systemic administration of corticosteroids; however, absorption from topical corticosteroids to the skin or even the gingiva may occur, especially in children. Primary pigmented nodular adrenocortical disease leading to Cushing syndrome occurs in 30% of patients with Carney complex. With alcohol abuse, the clinical findings of Cushing syndrome may be mimicked, producing the pseudo­Cushing syndrome. A cortisol level below 3 µg/dL essentially rules out Cushing syndrome, except for the iatrogenic variety, in which there is adrenocortical hypoplasia, and the serum cortisol level is very low, even without dexamethasone suppression. If this test is positive, it must be confirmed by doing a 24-hour urinary free cortisol test. A value of at least three times the upper limit of normal is 95­100% sensitive and specific. Treatment is primarily surgical removal of the tumor; however, radiation, chemotherapy, or medication that blocks steroid synthesis is occasionally used. EjazS,etal: Cushing syndrome secondary to ectopic adrenocorticotropic hormone secretion. Pichardo-LowdenA,etal: Cushing syndrome related to gingival application of a dexamethasone-containing preparation. Patient with acromegaly of hand on the left compared with normal-sized hand on the right. Palmar crease darkening in patients of lighter skin type, scar hyperpigmentation, and darkening of nevi, mucous membranes, hair, and nails may all be seen. Decreased axillary and pubic hair is seen in women, because their androgen production primarily occurs in the adrenals. Systemic signs such as weight loss, nausea, vomiting, diarrhea, weakness, fatigue, and hypotension add specificity to the cutaneous abnormalities. Hyperpigmentation may precede neurologic signs, so very-long-chain fatty acid levels should be determined. The cutaneous signs of excessive androgen in women include acne, hirsutism, temporal balding and androgeninduced patterned scalp hair loss, seborrhea, enlargement of the clitoris, and decreased breast size. Hyperpigmentation of the skin, areolae, genitalia, palmar creases, and buccal mucosa develops in some patients. Females may also develop a deepening voice, increased muscle mass, galactorrhea, and irregular or absent periods. In the congenital adrenogenital syndrome, excess androgen is produced by an inherited defect in any of the five enzymatic steps required to convert cholesterol to cortisol. In girls, masculinization occurs, with the prominent cutaneous signs of excess androgen production. Acne with onset between ages 1 and 7 with physical findings suggestive of a hormonal disorder, such as sexual precocity, virilization, and growth abnormalities, should be referred to a pediatric endocrinologist. Acne that begins from ages 7 to 12 often manifests primarily as comedonal lesions in the central face. Unless there are other signs of androgen excess, these patients do not need a workup. Accelerated bone growth with early closure of the epiphyseal plates results in short stature. If the total testosterone concentration is greater than 200 ng/dL, ovarian imaging is indicated to assess for an ovarian tumor. Diffuse loss of body hair occurs, with axillary, pubic, and head hair being especially thin. Compromise of the pituitary gland is usually caused by a pituitary tumor, although infiltration, infection, trauma, hemorrhage, or hypothalamic tumors may be the etiology. Thyroid hormone, glucocorticoids, sex steroids, and growth hormones are low and require replacement. SariguzelN,etal: Dobrava hantavirus infection complicated by panhypopituitarism, Istanbul, Turkey, 2010. The question remains whether treatment with corticosteroid replacement results in better outcomes than empiric antiandrogen therapy. Treatment of the cutaneous signs of androgen excess is successful with an oral contraceptive and often also an androgenblocking agent such as cyproterone acetate, flutamide, or finasteride. Spironolactone, which competes for the androgen cytosol receptors, has proved useful as a systemic antiandrogen in the treatment of hirsutism and acne. Adrenal-androgenic female pattern alopecia may improve with topical minoxidil or spironolactone. Chorionic villous biopsy may identify homozygous adrenogenital female fetuses and allow for dexamethasone therapy to prevent intrauterine virilization of the external genitalia. Recent associations with hypothyroidism include lichen planopilaris and cutaneous sarcoidosis. Congenitalhypothyroidism Thyroid deficiency in fetal life produces the characteristic picture of cretinism at birth and in the next few months of life. Depending on the degree of thyroid deficiency, a wide variety of signs and symptoms may be evident. The main consequence of extreme thyroid deficiency is cretinism and its attendant mental retardation, but much more prevalent are lesser degrees of intellectual and neurologic deficits seen in areas of the world where iodized salt is still not routinely available. Disturbances in the amount, texture, and distribution of the hair with patchy alopecia are common. Wide-set eyes, a broad, flat nose, and periorbital puffiness characterize the face. A protuberant abdomen with umbilical hernia; acral swelling; coarse, dry, brittle nails; a clavicular fat pad; and hypothermia with cutis marmorata are also seen. Myxedema When lack of secretion of thyroid hormone is severe, myxedema is produced. The skin becomes rough and dry, and in severe cases of primary myxedema, ichthyosis vulgaris may be simulated. The facial skin is puffy; the expression is often dull and flat; macroglossia, swollen lips, and a broad nose are present; and chronic periorbital infiltration secondary to deposits of mucopolysaccharides frequently develops. Carotenemia may cause a yellow tint in the skin that is especially prominent on the palms and soles. Deficiency may be caused by iodine deficiency, late-stage Hashimoto autoimmune thyroiditis, or pituitary or hypothalamic disease causing central hypothyroidism, or it may be iatrogenic secondary to surgery, radioactive iodine treatment, or drug therapy with lithium, interferon, multikinase inhibitors, valproic acid, or bexarotene. It may also complicate anticonvulsant and minocycline hypersensitivity syndromes, appearing approximately 2 months after the eruption has resolved. Hypothyroidism produces various clinical manifestations, depending on the age when it occurs and on its severity. Patients with Turner and Down syndrome are predisposed to hypothyroidism and the production of thyroid autoantibodies. Coldness of hands and feet in the absence of vascular disease, sensitivity to cool weather, lack of sweating, tendency to put on weight, need for extra sleep, drowsiness in the daytime, and constipation all suggest possible hypothyroidism and the need for appropriate tests. Palmoplantar keratoderma may be a sign of hypothyroidism and will resolve after thyroid hormone replacement is given. In Hashimoto thyroiditis, the most common cause of hypothyroidism in the United States, thyroid peroxidase antibodies are present in 95% of patients and antithyroglobulin antibodies in 65%. FunakoshiT,etal: Risk of hypothyroidism in patients with cancer treated with sunitinib. The hair is thin and has a downy texture, and nonscarring diffuse alopecia may be observed. The skin may darken to produce a bronzed appearance or melanoderma; melasma of the cheeks is seen is some cases. Nail changes are present in approximately 5% of patients with Plummer nails, a concave contour of the plate with characteristic distal onycholysis. It usually occurs after treatment of hyperthyroidism and is frequently associated with exophthalmos and pretibial myxedema. It may, however, occasionally precede the thyrotoxicosis and has been recognized in euthyroid and hypothyroid patients. It can be confused clinically with acromegaly, pachydermoperiostosis, pulmonary osteoarthropathy, or osteoperiostitis, but the radiologic findings are pathognomonic. The morphology may vary from a nonpitting infiltration to nodules, plaques, and even an elephantiasic form where the skin is thickened, firm, and hyperpigmented from just below the knees to the feet. It may also occur infrequently during the course of Hashimoto thyroiditis and primary hypothyroidism. Patients with pretibial myxedema regularly have associated ophthalmopathy and occasionally thyroid acropachy. Improvement in the plaques of pretibial myxedema has resulted from intralesional injections of triamcinolone acetonide and with high-potency topical corticosteroids under 495 Hyperthyroidism 24 Endocrine Diseases occlusion. Compression stockings or complete decongestive physiotherapy, and a combination of manual lymphatic drainage, bandaging, and exercise, are useful and safe. Pentoxifylline, octreotide, plasmapheresis, and cytotoxic drugs have all been reported to help in small numbers of patients, but negative reports also exist. Urticaria may be seen in patients with thyroid autoantibodies and may clear with the administration of thyroid hormone, even in euthyroid patients. Treatment is with radioactive iodine or antithyroid drugs such as methimazole or propylthiouracil. ShiraiK,etal: Dramatic effect of low-dose oral steroid on elephantiasic pretibial myxedema. VannucchiG,etal: Treatment of pretibial myxedema with dexamethasone injected subcutaneously by mesotherapy needles. Most pronounced is faulty dentition when hypoparathyroidism is present during development of the permanent teeth.
