A disorder similar to scleromyxedema, nephrogenic fibrosing dermatopathy, has been reported in patients receiving renal dialysis. Lichen myxedematosus, an atypical form of papular mucinosis, is not associated with sclerosis and paraproteinemia; however, it may represent an early presentation of scleromyxedema.

Millions of Americans suffer from anxiety disorders. Many with panic disorder, social anxiety disorder, and/or generalized anxiety disorder present initially to their primary care clinician. Effective treatment is possible in a busy primary care setting; therapy involves patient education and pharmacotherapy. Once other potential causes of symptoms of an anxiety disorder have been ruled out, the first step is to reassure the patient that he or she has a psychological condition-a very common one-and that symptoms are not the result of an undiagnosed disease or "going crazy" or "losing control." Educate and inform patients that complete clinical remission is achievable, often with medication alone. Begin treatment on day 1 with a long-acting benzodiazepine-such as alprazolam XR or clonazepam-or with the anxiolytic agent buspirone; at the same time, start a selective serotonin reuptake inhibitor (SSRI). The anxiolytic agent allays acute somatic symptoms until the full effects of the SSRI are manifest (often 4 to 6 weeks). The anxiolytic can then be gradually tapered. Referral to a psychiatrist for psychotherapy may be indicated when a patient refuses or cannot tolerate drug therapy, or when response to therapy is inadequate.

Fonsecaea species have been reported as causative agents ofchromoblastomycosis, eumycetoma, and fungal pneumonitis.However, Fonsecaea rarely involves the CNS, with few cases ofcerebral infection reported in the literature. Fonsecaea monophoramay have greater neurotropic potential than other species ofthis genus. We describe a rare presentation of brain abscesscaused by F monophora in an immunocompromised renaltransplant patient. [Infect Med. 2008;25:469-473]

Previous case reports have suggested an association betweenhuman T-cell lymphotropic virus (HTLV) types 1 and 2infection and chronic nonprogressive HIV infection. Evidenceis lacking about the specifics of how the two are related. Wereport 2 cases of chronic nonprogressive HIV infection (of9 and 13 years' duration, respectively) in women in whomHTLV coinfection was diagnosed. These cases provide clinicalsupport that HTLV coinfection may serve as a protective factoragainst progression of HIV infection. Possible reasons for thisrelationship and potential future research are discussed.[Infect Med. 2008;25:416-420]

An enlarging mass was noted on the dorsum of the right fifth toe of a 2-month-old boy during a well-child examination. The firm, immobile mass measured approximately 1 cm in diameter. A congenital abnormality was suspected; the patient was referred to a plastic surgeon for consultation.

HIV infection was diagnosed in a 34-year-old man 3 years before he was hospitalized. The patient had a 2-week history of nausea; vomiting; and diffuse, intermittent, poorly localized abdominal pain. He had received radiotherapy and chemotherapy for Kaposi's sarcoma (KS) of the upper and lower extremities, which had been diagnosed 8 months earlier.

WNV first appeared in the United States in 1999.1 This infection "got no respect" even though it caused significant morbidity and mortality while crossing the United States unabated for the past 9 years. Patients died mainly of neuroinvasive complications such as encephalitis and a polio-like paralysis. The lack of respect became a reality to clinicians in Phoenix in 2004 when they found themselves poorly prepared to manage the many acutely ill patients affected by WNV. That there was a lack of practical information about how to manage WNV became readily apparent to these clinicians.

Cough, fever, diarrhea, and weight loss had disturbed a 52-year-old woman for 1 month. AIDS had been diagnosed 5 years earlier, but she had declined medical treatment. The patient's vital signs were stable when she was admitted to the hospital. Physical examination results were unremarkable except for thrush and mild, diffuse abdominal tenderness.

abstract: In the past, constrictive pericarditis was most often caused by tuberculosis. Today, however, it is more likely to be preceded by injury or trauma, infection, or previous cardiac surgery. Most patients with constrictive pericarditis present with dyspnea and have elevated jugular venous pressure. Other potential symptoms and signs include peripheral edema, abdominal fullness, hepatomegaly, ascites, and chest pain. Electrocardiography demonstrates nonspecific ST-segment and T-wave changes and generalized T-wave inversion or flattening. In many cases, chest radiography and CT reveal pericardial calcification, and echocardiography shows increased pericardial thickness and calcification. Treatment may include NSAIDs, corticosteroids, antibiotics, angiotensin-converting enzyme inhibitors, and diuretics. Surgery is the treatment of choice for chronic disease, and pericardiectomy is typically effective. (J Respir Dis. 2007;28(2):49-56)

An 11-year-old boy had generalized abdominal pain followed by nausea and vomiting. He had neither diarrhea nor fever. Examination revealed a flat, diffusely tender abdomen with no palpable masses. Pigmented macules were seen on his lips and buccal mucosa. A partial bowel resection had been performed 5 years ago because of intussusception.

Allopurinol, commonly used to treat patients with gout, has been known to cause hypersensitivity reactions. We report a case of drug-induced delayed multiorgan hypersensitivity syndrome secondary to allopurinol use. To the best of our knowledge, this is the first reported case of diffuse alveolar hemorrhage in a patient presenting with allopurinol-induced rash with eosinophilia and systemic symptoms.
