Hepatic angiomyelolipoma and tuberous sclerosis.

A patient with angiomyelolipoma of the liver, together with radiological evidence of pancreatic, renal and bony lesions characteristic of tuberous sclerosis, is described. Although the patient had no other clinical features of tuberous sclerosis, her daughter was found to suffer from the classical triad of this syndrome and also has had hepatic lipomatous lesions and bony involvement. This is the first histologically proven case of hepatic angiomyelolipoma associated with tuberous sclerosis.

The vascular supply of splenic autotransplants.

The close opposition of blood to phagocytic cells lining the pulp cords and marginal sinus has been proposed as a contributing factor in the clearance mechanism of the spleen. The vasculature of splenic autotransplants was investigated in rats using microcorrosion casts. Six-month-old splenic autotransplants and unoperated control spleens were selectively perfused and a methyl methacrylate cast was made. Scanning electron microscopy of these corroded casts was performed. In autotransplants, the marginal zone capillary network was abnormal with the fine network of capillaries replaced by dilated blood vessels. The red pulp cords were also found to be abnormal with increased diameter and loss of the fine saccular dilations found in normal spleens. The abnormally dilated capillaries and cords in the autotransplants may decrease antigen contact with these cells and hence explain previous reports of reduced phagocytic function.

Initial psychological response to parental death.

A cohort of patients seeking help at a clinical research center providing time-limited brief therapy for posttraumatic stress disorders was assembled. The single life event experienced by each was death of a parent. A nonequivalent comparison group was gathered by review of hospital death records. Both groups received the same type of evaluation interview and completed the same measures, which were similar to those done for both groups by the clinical interviewer. These data indicated that while both groups contained persons with medium to high distress levels, the patient group was most uniformly composed of such persons; when compared with the field-study group, the patient group had significant and important elevations of distress levels.
