[Herpetic encephalitis in adults: 23 cases].

OBJECTIVE: To study the clinical presentation, diagnosis, treatment and prognosis of the herpetic encephalitis in our environment. MATERIAL AND METHOD: During the past 12 years, 23 adults (age > 15 years) were treated for herpetic encephalitis in our centre. RESULTS: There were 14 males and 9 females. Ages ranged from 18 to 84 years (mean, 52.30 +/- 18.64 years). The hospital stay ranged from 5 to 64 days (mean, 26.74 +/- 15.41 days). Eleven patients were managed in the intensive care unit and nine patients required mechanical ventilation. The most frequent clinical features they were the level of conscience decrease and fever. The lymphocytic pleiocytosis was the most frequent discovery in cerebrospinal fluid. The temporal lobe lesions in the computed tomography scan appeared in 14 patients (61%). Four patients died, seven patients were asymptomatic or with minimum sequels and twelve patients developed they were disabled. CONCLUSIONS: The herpetic encephalitis is an uncommon illness. Intravenous acyclovir is recommended treatment and the corticosteroids use is controverted. The delay in the treatment beginning worsens the prognosis. Less than a third of the patients achieve the functional independence to discharge hospital.

[Correlation between sensitivity of the cytogenetic and cytological analysis and thoracoscopic findings in the study of malignant pleural effusions].

We studied 104 patients with pleural effusion. All underwent thoracoscopic exploration to allow direct examination of any pleural lesions present. At the same time pleural biopsies for histopathologic study and samples of pleural fluid for cytopathologic and cytogenetic study were taken. The volume of fluid in pleural cavity was also measured. The aims of the study were: a) to evaluate the sensitivity of cytogenetic analysis and cytopathology, both separately and together, and b) to look for a correlation between the sensitivity of these cell studies and the following thoracoscopic findings: tissue biopsy of pleural neoplasms, volume of pleural effusion and extension of neoplastic lesions in the pleural cavity. Seventeen of the pleural liquids studied were benign and 87 were neoplastic. Cytopathology was sensitive in 55% of the neoplastic cases and cytogenetic study was sensitive in 49%. Sensitivity rose to 74% when both techniques were applied. Cytogenetic study yielded a higher percentage of correct diagnoses in the group with hematologic neoplasia, whereas cytopathology was correct more often in cases of solid tumors, though these differences were not statistically significant. Use of both techniques resulted in correct diagnosis in 92% of patients with mesotheliomas. The number or correct diagnoses achieved with cytopathology tended to increase with size of macroscopic pleural lesion whereas cytogenetic study was more sensitive in patients with minimal or incipient pleural involvement. There were no statistically significant differences in sensitivity of cytopathology and cytogenetic analysis with regard to volume of pleural effusion.

[Venous hemangioma of the mediastinum: apropos of a case].

A case of mediastinal venous hemangioma is reported. It's a benign tumor rarely found in the mediastinum. In the last six years, we only know three cases reported and none of them in our country. Clinical manifestations were cough and pleuritic pain. The diagnosis was suggested by radiologic examination and was confirmed by histologic study after thoracotomy. The mass was totally removed surgically and the evolution of the patient was favorable.
