Kaposi's sarcoma mimicking cellulitis.

Although Kaposi's sarcoma is not the most common cause of death in AIDS patients, it is often one of the initial opportunistic illnesses associated with human immunodeficiency virus infection. Extensive plaque formation and edema in the lower extremities may take on the appearance of cellulitis, and in dark-skinned persons, the lesions of the neoplasm may not be noticeable. Treatment is palliative; therapy for local effect is appropriate unless lesions are extensive or systemic involvement is present.

Lithium-induced nephrogenic diabetes insipidus treated with indomethacin.

NDI occurs in 5% to 20% of patients receiving long-term lithium therapy. The associated polyuria usually resolves within 3 weeks of lithium discontinuance but can persist beyond a year. For such patients, hydrochlorothiazide and amiloride therapy has been hampered by the delayed effect and intrinsic side effects of these agents. We have described the case of a 66-year-old man with a history of bipolar disorder treated with lithium who was transferred to the intensive care unit with coma. Indomethacin therapy, at a dose of 50 mg every 8 hours, was begun and improvement of the NDI state was observed within 3 hours of lithium administration. There was complete normalization of mental status and laboratory studies after 36 hours. A complete 3-week course of indomethacin was required to keep the patient free of symptoms of NDI. We have also discussed the role of indomethacin in reversing lithium-induced NDI and reviewed pertinent prior reports in the literature.

BK virus.

BK virus is a human polyoma virus that infects the renal epithelium and remains latent until immunosuppression triggers reactivation. After reactivation, BK virus can be detected in the urine by methods currently available in the clinical laboratory. Correlations can be made between BK viruria and the occurrence of both renal and hepatic pathologies. BK virus is emerging as a significant pathogen in transplant patients. Additionally, the presence of BK virus DNA in primary brain and pancreatic tumors suggests that it may have oncogenic potential. Thus far, attempts to treat BK virus infection have been ineffective, though research has opened new avenues for treatment possibilities. Prevention of BK virus and other latent viral reactivation remains a challenge to viral research.
