Opportunistic agents in bronchoalveolar lavage in 99 HIV seropositive patients.

During a ten month period, 117 fibreoptic bronchoscopies and bronchoalveolar lavages (BAL) were performed in human immunodeficiency virus (HIV) infected patients suspected of having opportunistic pulmonary infections. The BAL were classified into 3 groups, according to clinical manifestations related to HIV infection at the time of fibreoptic bronchoscopy: pre-acquired immunodeficiency syndrome (AIDS) (n = 54), AIDS with Kaposi's sarcoma (n = 37), AIDS without Kaposi's sarcoma (n = 26). On chest X-ray, diffuse infiltrates were most common (54%), followed by normal X-rays (24%) and localized infiltrates (18%). Amongst the 117 BAL, 68 (58%) yielded at least one opportunistic agent. In 28 BAL performed for pulmonary signs or unexplained fever with normal chest X-rays, one or several opportunistic agents were isolated in 17 samples of BAL fluid. The most frequently identified opportunistic agents were Pneumocystis carinii (in 38% of BAL) and cytomegalovirus (35%); these were associated in 17% of BAL. There was no statistically significant difference in opportunistic agents among the 3 groups of BAL (pre-AIDS, AIDS with Kaposi's sarcoma, AIDS without Kaposi's sarcoma). In particular, cytomegalovirus was found in BAL with the same frequency in these 3 groups.

[Aortic-pulmonary chemodectoma (non-chromaffin paraganglioma). Apropos of a case which followed an adrenal pheochromocytoma].

The authors present the 61st published case of an aorticopulmonary chemodectoma diagnosed in patient of 59 years who had been operated on 7 years previously for a right sided adrenal pheochromocytoma. The diagnosis was provided by the histological examination of the operative specimen, since computerised tomography had predicted that this large hypervascular tumour of the anterior mediastinum would be totally resectable.

[A rare tumor of the mediastinum: benign hemangioma].

Mediastinal hemangiomas are rare tumours occurring more often in children and young adults. A new case is reported in a 21 years old male who had an anterior mediastinal mass detected on a routine chest roentgenogram. Pre-operative investigations including CT, venous digital angiography, MRI did not aid in the right diagnosis. The mass was totally removed surgically although involving extensively adjacent structures. Histologic examination of the tumour showed it to be a benign venous hemangioma. Clinical, radiological, pathologic features of mediastinal hemangiomas are reviewed and discussed.
