Idiopathic retroperitoneal fibrosis: a report of 3 cases.

Case histories of three male patients diagnosed as idiopathic retroperitoneal fibrosis either on autopsy or following intra-operative biopsy are reported. Two of them were in the 5th decade and one aged 22 yrs. All of them presented with features of urinary tract obstruction and renal failure. The obstruction was detected either by ultrasonography or following ascending pyelogram. One of them underwent peritoneal dialysis but later on died of sudden cardiac arrest. The remaining two underwent surgery, during which a biopsy was taken. Histological examination in all the three patients revealed fibroblastic proliferation and mononuclear cell infiltration. Features of chronic periaortitis were also found in the autopsy specimen of descending aorta of the first patient. Both the elderly patients had aortic atherosclerosis which is suspected to be the etiological factor for fibrosis. However in the young male patient intense eosinophilic infiltrate was observed in biopsy material pointing towards 'hypersensitivity' reaction as a cause for fibrosis.

Pneumocystis carinii pneumonia in human immunodeficiency virus infected patients in Bombay: diagnosed by bronchoalveolar lavage cytology and transbronchial lung biopsy.

We report Pneumocystis carinii pneumonia (PCP) diagnosed by bronchoalveolar lavage cytology and transbronchial lung biopsy in three out of five human immunodeficiency virus (HIV) positive adult patients presenting with interstitial pneumonitis. One of these patients was serologically positive for HIV at the time of presentation and the remaining two patients were detected to be HIV positive on follow up after the diagnosis had been established. All the three patients were treated with co-trimoxazole. One patient recovered and was discharged; another patient improved with treatment but died after jugular vein cannulation and the third patient succumbed to cryptosporidial diarrhoea. The remaining two patients with non-specific interstitial pneumonitis treated with prednisolone and bronchodilators were recovered and were discharged from the hospital.

Aortic dissections: a pathologic study of 35 autopsied cases.

A study of 35 autopsied cases of aortic dissection collected over a period of 12 years was carried out. There were 25 males and 10 females, and the majority of the dissections presented in fourth to fifth decade of life. Thirty-six dissections were present in 35 cases. Type III was the commonest (50.0%), followed by Type I (41.7%) and Type II (8.3%) dissections. Rupture following acute dissection was the cause of death in 15 patients. In chronic types, the causes of death were not related to dissection. Hypertension, connective tissue disorders and trauma were identified as some of the risk factors.
