Tratamento da leishmaniose tegumentar americana, com lesäo em mucosa, por meio do isotionato de pentamidina / Treatment of mucocutaneous leishmaniasis, with mucosal lesion, with pentamidine isothianate

Ten patients with mucosal lesions caused by American tegumental leishmaniasis were treated with pentamidine isethionate at the dose 4 mg/kg on alternate days by the intravenous route. The mean posology was 2,140 mg. Healing of the lesions occurred in 9 (90 per cent) of the patients who completed treatment. There was no recurrence during a follow-up time of 1 to 24 months (mean, 7,7 months). One patient discontinued treatment before healing of the lesion because be developed diabetes mellitus. In 3 (30 per cent) patients, blood exams showed increased urea and creatinine levels and leucopenia, which were corrected by increasing the interval between administrations of the drug. Pentamidine isethionate is efficient in bringing about cicatrization of the lesions but needs further evaluation in terms of its value in preventing recurrence.

Parotid enlargement due to adenovirus infection in patient with human immunodeficiency virus infection

The authors report a case of adenovirus-induced enlargement of the parotid gland involving a patient infected with human immunodeficiency virus (HIV). Physical examination revealed good general condition, no fever and bilateral enlargement of the parotid region, which was of increased consistency and slightly tender to palpation. Histological examination of the parotid gland demonstrated a slight periductal lymphomononuclear inflammatory infiltrate with the presence of focal points of necrosis. Tests to determine the presence of fungi and alcohol-acid resistant bacilli were negative. Immunohistochemistry for cytomegalovirus, herpes simplex, HIV p24 antigen and adenovirus showed positivity only for adenovirus in the epithelial nuclei of numerous gland ducts. This is the third case of this type reported in the literature, indicating the importance of including adenovirus in the differential diagnosis of this condition.
