After the patient is stabilized red carpet treatment generic diamox 250 mg buy online, the appropriate form of long-term management of the diabetes must be deter mined. Insulin treatment should be continued for a few weeks but patients usually recover sufficient endogenous insulin secretion to make a trial of diet or diet plus oral agents worthwhile. When the episode occurs in a patient who has known diabetes, then education of the patient and caregivers should be instituted. They should be taught how to recognize situations (nausea and vomiting, infection) that predispose to recurrence of the hyperglycemic, hyper osmolar state, as well as detailed information on how to prevent the escalating dehydration that culminates in hyperosmolar coma (small sips of sugar-free liquids, increase in usual hypoglycemic therapy, or early contact with the clinician). Most cases of metformin -associated lactic acidosis occur in patients in whom there were contraindications to the use of metformin, in particular kidney failure. Symptoms and Signs the main clinical feature of lactic acidosis is marked hyperventilation. When lactic acidosis is secondary to this sue hypoxia or vascular collapse, the clinical presentation is variable, being that of the prevailing catastrophic illness. However, in the idiopathic, or spontaneous, variety, the onset is rapid (usually over a few hours), blood pressure is normal, peripheral circulation is good, and there is no cyanosis. Laboratory Findings Plasma bicarbonate and blood pH are quite low, indicating the presence of severe metabolic acidosis. The first clue may be a high anion gap (serum sodium minus the sum of chloride and bicarbonate anions [in mEq/L] should be no greater than 1 5). If this cannot be clinically explained by an excess of keto acids (diabetes), inorganic acids (uremia), or anions from medication overdosage (salicylates, methyl alcohol, ethylene glycol), then lactic acidosis is probably the correct diagnosis. The diagnosis is confirmed by demonstrating, in a sample of blood that is promptly chilled and separated, a plasma lactic acid con centration of 5 mmoi! Normal plasma values aver age 1 mmol/L, with a normal lactate/pyruvate ratio of 1 0: 1. Treatment Aggressive treatment of the precipitating cause of lactic acidosis is the main component of therapy, such as ensur ing adequate oxygenation and vascular perfusion of tissues. Empiric antibiotic coverage for sepsis should be given after culture samples are obtained in any patient in whom the cause of the lactic acidosis is not apparent. General Considerations Lactic acidosis is characterized by accumulation of excess lactic acid in the blood. Normally, the principal sources of this acid are the erythrocytes (which lack enzymes for aerobic oxidation), skeletal muscle, skin, and brain. Con version of lactic acid to glucose and its oxidation princi pally by the liver but also by the kidneys represent the chief pathways for its removal. Overproduction of lactic acid (tissue hypoxia), deficient removal (hepatic failure), or both (circulatory collapse) can cause accumulation. Lactic acidosis is not uncommon in any severely ill patient suffer ing from cardiac decompensation, respiratory or hepatic failure, septicemia, or infarction of bowel or extremities.
Although low serum testosterone levels may con tribute to hypoactive sexual desire disorder treatment pneumonia diamox 250 mg discount, hysterectomy and sexual isolation are major causes. Low serum testoster one levels may also cause fatigue, a diminished sense of well being, and a dulled enthusiasm for life. Methyltestosterone can be compounded into cap sules and taken orally in doses of 1. Testosterone can also be compounded as a cream contain ing 1 mg/mL, with 1 mL applied to the abdomen daily. The latter formulations are convenient but carry the same disadvantages as oral estrogen particularly an increased risk of thromboembolism. Treatment of symptoms of the menopause: an Endocrine Society clinical practice guideline. Turner syndrome comprises a group of X chromosome disorders that are associated with spontaneous abortion, primary hypogonadism, short stature, and other pheno typic anomalies (Table 26- 1 7). It affects 1 -2% of fetuses, of which about 97% abort, accounting for about 10% of all spontaneous abortions. Sym ptoms and Signs Features of Turner syndrome are variable and may be sub tle in girls with mosaicism. Turner syndrome may be diag nosed in infant girls at birth, since they tend to be small and may exhibit severe lymphedema. Girls and women with Turner syndrome have an increased risk of aortic coarctation (1 1 %) and bicuspid aortic valves (1 6%); these cardiac abnormalities are more common in patients with a webbed neck. If a woman with Turner syndrome becomes pregnant, there is a 2% risk of death from aortic dissection or rupture. Typical manifestations in adulthood include short stature, hypogonadism, webbed neck, high arched palate, wide-spaced nipples, hypertension, and renal abnormalities (Table 26- 1 7). Affected women are also more prone to autoim mune disease, particularly thyroiditis (37%), inflammatory bowel disease (4%), and celiac disease (3%). Such girls tend to be taller and may have more gonadal function and fewer other manifestations of Turner syndrome. Patients may have ambiguous genitalia or male infertility with an otherwise normal phe notype. Increased maternal cardiovascular mortality asso ciated with pregnancy in women with Turner syndrome. After age 12 years, estrogen therapy is begun with low doses of conjugated estrogens (0. Partial anomalous pulmonary vein connections occur in 1 3 % and can lead to left-to-right shunting of blood. Women with Turner syndrome have a reduced life expectancy due in part to their increased risk of diabetes mellitus (types 1 and 2), hypertension, dyslipidemia, and osteoporosis. Diagnostic vigilance and aggressive treatment of these conditions reduce the risk of aortic aneurysm dissection, ischemic heart disease, stroke, and fracture. The risk of aortic dissection is increased more than 1 00-fold in women with Turner syndrome, particularly those with pronounced neck web bing and shield chest.
There has been no change to the peni cillin susceptibility breakpoint for pneumococcal isolates causing meningitis medicine valley high school purchase 250 mg diamox mastercard, nor any change in treatment recommendations. Patients should be monitored for clinical response (eg, less cough, defervescence within 2-3 days) because pneumococci have become increasingly resistant to penicillin and the second-line agents. Parenteral therapy is generally recommended for the hospitalized patient at least until there has been clinical improvement. For serious penicillin allergy or infection caused by a highly penicillin-resistant strain, vancomycin, 1 g intra venously every 12 hours, is effective. Alternatively, a respi ratory fluoroquinolone (eg, levofloxacin, 750 mg) can be used. The total duration of therapy is not well defined but 5-7 days is appropriate for patients who have an uncompli cated infection and demonstrate a good clinical response. Treatment of Compl ications Pleural effusions developing after initiation of antimicro bial therapy usually are sterile, and thoracentesis need not be performed if the patient is otherwise improving. Thora centesis is indicated for an effusion present prior to initia tion of therapy and in the patient who has not responded to antibiotics after 3-4 days. Chest tube drainage may be required if pneumococci are identified by culture or Gram stain, especially if aspiration of the fluid is difficult. In patients with increas ing effusion, unsatisfactory clinical response, or evidence of tamponade, pericardiocentesis will determine whether the pericardia! Infected fluid must be drained either percutaneously (by tube placement or nee dle aspiration), by placement of a pericardia! Pericardiectomy eventually may be required to prevent or treat constrictive pericarditis, a common sequela of bacterial pericarditis. Endocarditis should be treated for 4 weeks with 3-4 million units of penicillin G every 4 hours intravenously; ceftriaxone, 2 g once daily intravenously; or vancomycin, 15 mg/kg every 12 hours intravenously. Mild heart failure from endocarditis may respond to medical therapy, but moderate to severe heart failure is an indication for pros thetic valve implantation, as are systemic emboli or large friable vegetations as determined by echo cardiography. This change reflected results from studies demon strating equivalent cure rates when high doses of paren teral penicillin were used for treatment of pneumococcal =. When to Refer All patients with suspected pneumococcal endocarditis or meningitis to an infectious disease specialist. Seriously ill patient with pneumonia, particularly in the setting of comorbid conditions (eg, liver disease). When to Ad m it All patients in whom pneumococcal endocarditis or meningitis is suspected or documented should be admitted for observation and empiric therapy. All patients with pneumococcal pneumonia that is mul tilobar or associated with significant hypoxemia. Failure of outpatient pneumonia therapy, including inability to maintain oral intake and medications. Exacerbations of underlying disease (eg, heart failure) by pneumonia that would benefit from hospitalization. General Considerations S pneumoniae is the most common cause of meningitis in adults.
Endocrine tumours: progressive metastatic med ullary thyroid carcinoma: first- and second-line strategies symptoms yellow fever cheap diamox 250mg with visa. Adjuvant radioactive iodine therapy is associated with improved survival for patients with intermediate-risk papillary thyroid cancer. General Considerations Considerable progress has been made to improve global iodine nutrition. However mild-to- moderate and sometimes severe iodine deficiency persists in 30 countries. Although iodine deficiency is the most common cause of endemic goiter, there are other natural goitrogens, including certain foods (eg, sorghum, millet, maize, cas sava), mineral deficiencies (selenium, iron, zinc), and water pollutants, which can themselves cause goiter or aggravate a goiter proclivity caused by iodine deficiency. Pregnancy aggravates iodine deficiency and is associated with an increase in size of thyroid nodules and the emergence of new nodules. Some individuals are par ticularly susceptible to goiter owing to congenital partial defects in thyroid enzyme activity. Substernal goiters are usually asymptomatic but can cause tracheal compression, respiratory distress and fail ure, dysphagia, superior vena cava syndrome, gastrointesti nal bleeding from esophageal varices, palsies of the phrenic or recurrent laryngeal nerves, or Horner syndrome. Cere bral ischemia and stroke can result from arterial compres sion or thyrocervical steal syndrome. Others may become thyrotoxic as the goiter grows and becomes more autonomous, especially if iodine is added to the diet. Serum levels of antithyroid antibodies are usu ally either undetectable or in low titers. Differential Diagnosis Endemic goiter must be distinguished from all other forms of nodular goiter that may coexist in an endemic region. The minimum dietary require ment for iodine is about 50 meg daily, with optimal iodine intake being 1 50-300 meg daily. Iodine sufficiency is assessed by measurement of urinary iodide excretion, the target being more than 10 mcg/dL. Initiating iodine sup plementation in an iodine-deficient area greatly reduces the emergence of new goiters but causes an increased fre quency of hyperthyroidism during the first year. Treatment the addition of potassium iodide to table salt greatly reduces the prevalence of endemic goiter and cretinism but is less effective in shrinking established goiter. Salt was iodized (30 mg of potassium iodate per kg salt) and made available in 1985. Iodine supplementation has not proven effective for treating adults with large multinodular goiter and actually increases their risk of developing thyrotoxicosis. Thyroidec tomy may be required for cosmesis, compressive symptoms, or thyrotoxicosis.
Mutations in genes associated with T cell tolerance can also cause autoimmune diabetes ombrello glass treatment diamox 250mg free shipping. These antibodies facilitate screening for an autoimmune cause of diabetes, particularly screening sib lings of affected children, as well as adults with atypical features of type 2 diabetes mellitus. Also, low levels of anti insulin antibodies develop in almost all patients once they are treated with insulin. Family members of diabetic probands are at increased lifetime risk for developing type l diabetes mellitus. If one haplotype is shared, the risk is 6% and if two haplotypes are shared, the risk increases to 1 2-25%. Some patients with a milder expression of type l diabe tes mellitus initially retain enough B cell function to avoid ketosis, but as their B cell mass diminishes later in life, dependence on insulin therapy develops. Evidence for environmental factors playing a role in the development of type l diabetes include the observation that the disease is more common in Scan dinavian countries and becomes progressively less frequent in countries nearer and nearer to the equator. Also, the risk for type l diabetes increases when individuals who nor mally have a low risk emigrate to the Northern Hemi sphere. For example, Pakistani children born and raised in Bradford, England have a higher risk for developing type 1 diabetes compared with children who lived in Pakistan all their lives. Also, in developed countries, childhood infections have become less frequent and so perhaps the immune system becomes dysregulated with development of autoimmunity and conditions such as asthma and diabe tes. Part of the difficulty in determining the causative environ mental factor is that autoimmune injury is initiated many years before the clinical presentation of diabetes. Circu lating endogenous insulin is sufficient to prevent ketoaci dosis but is inadequate to prevent hyperglycemia in the face of increased needs owing to tissue insensitivity (insu lin resistance). Genetic and environmental factors combine to cause both the insulin resistance and the beta cell loss. Most epi demiologic data indicate strong genetic influences, since in monozygotic twins over 40 years of age, concordance develops in over 70% of cases within a year whenever type 2 diabetes develops in one twin. A significant number of the identified loci appear to code for proteins that have a role in beta cell function or development. Early in the disease process, hyperplasia of pancreatic B cells occurs and probably accounts for the fasting hyperin sulinism and exaggerated insulin and proinsulin responses to glucose and other stimuli. With time, chronic deposition of amyloid in the islets may combine with inherited genetic defects progressively to impair B cell function. The degree and prevalence of obesity varies among different racial groups with type 2 diabetes. While obesity is apparent in no more than 30% of Chinese and Japanese patients with type 2, it is found in 60-70% of North Americans, Europeans, or Africans with type 2 and approaches l 00% of patients with type 2 among Pima Indians or Pacific Islanders from Nauru or Samoa. Visceral obesity, due to accumulation of fat in the omental and mesenteric regions, correlates with insulin resistance; subcutaneous abdominal fat seems to have less of an association with insulin insensitivity.
Syndromes
Hypo calcemia occurs frequently treatment bee sting diamox 250 mg on line, resulting in secondary hyper parathyroidism; such patients may be treated with oral calcium supplements (500- 1 000 mg/ day) and with oral vitamin D 3 (starting at 1 000 units/day). Denosumab-Denosumab (Prolia, Xgeva) is a monoclo nal antibody that inhibits the proliferation and maturation of preosteoclasts into mature osteoclast bone-resorbing cells. It is also used for patients with high fracture risk who are receiving sex hormone suppression therapy for breast cancer or prostate cancer. Unlike bisphosphonates, deno sumab can be given to patients with severe kidney disease. It can decrease serum calcium and should not be administered to patients with hypocalcemia. Other side effects include hypercholesterolemia, eczema and dermatitis, serious infections, new malignancies, and pancreatitis. With prolonged use, it predisposes to atypical femoral frac tures and osteonecrosis of the jaw and is additive to bisphosphonates in that regard. Teriparatide stimulates the production of new collagenous bone matrix that must be mineralized. Patients receiving teriparatide must have sufficient intake of vitamin D and calcium. When administered to patients with osteo porosis in doses of 20 meg/day subcutaneously for 2 years, teriparatide dramatically improves bone density in most bones except the distal radius. Teriparatide may also be used to promote healing of atypical femoral chalkstick fractures associated with bisphosphonate therapy. The recommended dose should not be exceeded, since teriparatide has caused osteosarcoma in rats when administered in very high doses. Due to the potential risk for osteosarcoma, patients are excluded from receiving teriparatide if they have an increased risk of osteosarcoma due to the following: Paget disease of bone, unexplained elevations in serum alkaline phosphatase, prior radiation therapy to bones, open epiphyses, or a past history of osteosarcoma or chondrosarcoma. Side effects may include inj ection site reactions, orthostatic hypoten sion, arthralgia, muscle cramps, depression, or pneumonia. Hypercalcemia can occur and manifest as nausea, constipa tion, asthenia, or muscle weakness. Following a course of teriparatide, bisphosphonates should be considered in order to retain the improved bone density. Alternatively, for severe osteoporosis, teriparatide may be administered along with denosumab; combined treatment for 2 years is more effective than any other single therapy. Orthopedic surgery- Percutaneous vertebroplasty or kyphoplasty may be considered for p atients with verte bral compression fractures who fail conservative pain management.
Recognized sequelae include central hypoventilation medicine nobel prize 2015 diamox 250 mg buy low cost, dysphagia, and limb weakness. Clinical and epidemiologic findings aided by isolation of the suspect agent from conjunctival scraping for entero virus 70; vesicle swabs, body secretions, or cerebrospinal fluid for enterovirus 7 1; and respiratory secretions for D68 facilitate diagnosis of these enteroviral entities. Enzyme immunoassays and complement fixation tests show good specificity but poor sensitivity (less than 80%). The major complication associated with enterovirus 70 is the rare development of an acute neurologic illness with motor paralysis akin to poliomyeli tis. Intravenous immunoglobulin was anecdotally successful in one case of parechovirus dilated cardiomyopathy. Reported complications of neonatal cerebral infections include learn ing disabilities, epilepsy, and cerebral palsy. Human parechovirus type 3 and 4 associ ated with severe infections in young children. Household contacts, especially children under 6 months of age, are at particular risk for enterovirus 7l acquisition. A commercial disinfectant, Virkon S, at l -2% application, appears to reduce infectivity titers. Decreases in antibody titers suggest booster doses of these vaccines may be needed. Enterovirus 7 1 infection -associated acute flaccid paralysis: a case series of long-term neurologic follow-up. Severe respiratory illness associated with entero virus D68-Missouri and Illinois, 2014. The pathogen mainly affects small children during the summer and early fall, although disease can also occur in older adults. Clinical presentation is mainly driven by gastrointestinal and respiratory illness, although otitis, neonatal sepsis, flaccid paralysis, myalgias, diffuse maculopapular and palmar-plantar rashes, aseptic menin gitis, and encephalitis are described in the literature. Human parechoviruses are one of the leading causes of viral sepsis and meningitis in young children. General Considerations Epidemic louse-borne typhus is caused by Rickettsia prowa zekii, an obligate parasite of the body louse Pediculus humanus corporis (Table 32-4). After biting a person infected with R prowazekii, the louse becomes infected by the organism, which persists in the louse gut and is excreted in its feces. When the same louse bites an uninfected individual, the feces gain entry into the bloodstream when the person scratches the itching wound. Cases can be acquired by travel to pockets of infection (eg, central and northeastern Africa, Central and South America). A variety of other acute febrile diseases should be considered, including typhoid fever, meningococcemia, and measles. In the United States, cases occur among the homeless, refu gees, and the unhygienic, most often in the winter.
Phosphate deficiency in childhood causes classic rickets medicine reminder alarm cheap diamox 250mg with visa, whereas phosphate deficiency in adulthood causes osteomalacia. Fi brogenesis lmperfecta Ossium this rare condition sporadically affects middle-aged patients, who present with progressive bone pain and pathologic fractures. Some patients have a monoclonal gammopathy, indicating a possible plasma cell dyscrasia causing an impairment in osteoblast function and collagen disarray. Remission has been reported after repeated courses of mel phalan, corticosteroids, and vitamin D analog over 3 years. The condition is character ized by hypophosphatemia, excessive phosphaturia, reduced or normal serum 1,25(0H) 2 D concentrations, and osteomalacia. Such tumors are often small and difficult to find, frequently lying in extremities. Other causes of hypophosphatemia- Osteomalacia from hypophosphatemia can be caused by severe intestinal malabsorption or poor nutrition. Severe hypophosphate mia can occur with refeeding after starvation (eg, concen tration camp victims, malnourished alcoholics). Other causes of hypophosphatemia include respiratory alkalosis, glucose infusions, salicylate intoxication, mannitol, and bisphosphonate therapy. Additional causes include chela tion of phosphate in the gut by aluminum hydroxide antac ids, calcium acetate (Phos-Lo), or sevelamer hydrochloride (Renagel). Excessive renal phosphate losses are also seen in proximal renal tubular acidosis and Fanconi syndrome. Clinical Findings the clinical manifestations of defective bone mineraliza tion depend on the age at onset and the severity. Eventually, bone and j oint pain occurs, along with reduced muscle strength and endurance. In one series of biopsy-proved osteomalacia, alkaline phosphatase was elevated in 94% of patients; the calcium or phosphorus was low in 47% of patients; 25(0H)D 3 was low in 29% of patients; pseudofractures were seen in 1 8 % of patients; and urinary calcium was low in 1 8 % of patients. Osteoma lacia may occur in patients receiving long-term renal hemodialysis with tap water dialysate or from aluminum containing antacids used to reduce phosphate levels. Osteomalacia may develop in patients being maintained on long-term total parenteral nutrition if the casein hydro lysate used for amino acids contains high levels of aluminum. It is a rare genetic cause of osteomalacia that is commonly misdiagnosed as osteoporo sis. The incidence in the United States is about 1 in 1 00,000 live births; about 1 in 300 adults is a carrier. At its mildest, hypophosphatasia can present in middle age with premature loss of teeth, foot pain (due to metatarsal stress fractures), thigh pain (due to femoral pseudofrac tures), or arthritis (due to chondrocalcinosis).
Screening of at-risk individuals for infection is appropriate before institution of immunosuppressive ther apy medications migraine headaches buy diamox 250 mg amex. Screening can consist of serologic tests, with stool examinations in those with positive serologic tests, but consideration of presumptive treatment even if the stool evaluations are negative (see below). A related parasite, Strongyloides fuelleborni, infects humans in parts of Africa and New Guinea. Among nematodes, S stercora/is is uniquely capable of maintaining its full life cycle both within the human host and in soil. Infection occurs when filariform larvae in soil penetrate the skin, enter the bloodstream, and are carried to the lungs, where they escape from capillaries into alveoli, ascend the bronchial tree, and are then swallowed and car ried to the duodenum and upper jejunum, where matura tion to the adult stage takes place. Females live embedded in the mucosa for up to 5 years, releasing eggs that hatch in the intestines as free rhabditiform larvae that pass to the ground via the feces. Autoinfection can occur in humans, when some rhabditiform larvae develop into filariform larvae that penetrate the intestinal mucosa or perianal skin, and enter the circulation. The most dan gerous manifestation of S stercora/is infection is the hyper infection syndrome, with dissemination of large numbers of filariform larvae to the lungs and other tissues in immu nocompromised individuals. Mortality with this syn drome approaches 1 00% without treatment and has been about 25% with treatment. Sym ptoms and Signs As with other intestinal nematodes, most infected persons are asymptomatic. An acute syndrome can be seen at the time of infection, with a pruritic, erythematous, maculo papular rash, usually of the feet. These symptoms may be followed by pulmonary symptoms (including dry cough, dyspnea, and wheezing) and eosinophilia after a number of days, followed by gastrointestinal symptoms after some weeks, as with hookworm infections. Chronic infection may be accompanied by epigastric pain, nausea, diarrhea, and anemia. Maculopapular or urticarial rashes of the buttocks, perineum, and thighs, due to migrating larvae, may be seen. Gastrointestinal symptoms can include abdomi nal pain, nausea, vomiting, diarrhea, and more severe find ings related to intestinal obstruction, perforation, or hemorrhage. Bacterial sepsis, probably secondary to intes tinal ulcerations, is a common presenting finding. Pulmo nary findings include pneumonitis, cough, hemoptysis, and respiratory failure. Treatment Full eradication of S stercora/is is more important than with other intestinal helminths due to the ability of the parasite to replicate in humans. The treatment of choice for routine infection is ivermectin (200 meg orally daily for l -2 days). This treatment has replaced thiabendazole (25 mg/kg orally twice daily for 3 days), which is relatively poorly tolerated, and albendazole (400 mg orally twice daily for 3 days), which is less effective. For hyperinfec tion, ivermectin should be administered daily until the clinical syndrome has resolved and larvae have not been identified for at least 2 weeks. Follow-up examinations for larvae in stool or sputum are necessary, with repeat dosing if the infection persists.
The skin lesions of leprosy often resemble those of lupus erythematosus treatment jiggers order 250 mg diamox amex, sarcoidosis, syphilis, erythema nodosum, erythema multiforme, cutaneous tuberculosis, and vitiligo. Complications Kidney failure and hepatomegaly from secondary amyloi dosis may occur with long-standing disease. General Considerations Leprosy (Hansen disease) is a chronic infectious disease caused by the acid-fast rod M leprae. The mode of trans mission probably is respiratory and involves prolonged exposure in childhood. The disease is endemic in tropical and subtropical Asia, Africa, Central and South America, and the Pacific regions, and rarely seen sporadically in the southern United States. Treatment Combination therapy is recommended for treatment of all types of leprosy. Single-drug treatment is accompanied by emergence of resistance, and primary resistance to dap sone also occurs. For borderline and lepromatous cases (ie, multibacillary disease), the World Health Organiza tion recommends a triple oral drug-regimen of rifampin, 600 mg once a month; dapsone, 100 mg daily; and clofazi mine, 300 mg once a month and 50 mg daily for 12 months although longer courses may be needed for patients with high burden of disease. For indeterminate and tuberculoid leprosy (paucibacillary disease), the rec ommendation is rifampin, 600 mg once a month, plus dapsone, 1 00 mg daily for 6 months. Two reactional states-erythema nodosum leprosum and reversal reactions-may occur as a consequence of therapy. The reversal reaction, typical of borderline lepro matous leprosy, probably results from enhanced host immunity. Skin lesions and nerves become swollen and tender, but systemic manifestations are not seen. Erythema nodosum leprosum, typical of lepromatous leprosy, is a consequence of immune injury from antigen-antibody complex deposition in skin and other tissues; in addition to skin and nerve manifestations, fever and systemic involve ment may be seen. Prednisone, 60 mg/day orally, or tha lidomide, 300 mg/day orally (in the nonpregnant patient only), is effective for erythema nodosum leprosum. Improvement is expected within a few days after initiating prednisone, and thereafter the dose may be tapered over several weeks to avoid recurrence. The lesions involve the cooler body tissues: skin, superficial nerves, nose, pharynx, larynx, eyes, and testicles. Skin lesions may occur as pale, anes thetic macular lesions 1 - 1 0 em in diameter; discrete ery thematous, infiltrated nodules 1 - 5 em in diameter; or diffuse skin infiltration. Neurologic disturbances are caused by nerve infiltration and thickening, with resultant anesthesia, and motor abnormalities. In untreated cases, disfigure ment due to the skin infiltration and nerve involvement may be extreme, leading to trophic ulcers, bone resorption, and loss of digits.
