Sarcoidosis with renal involvement.

Nine of ninety patients with sarcoidosis were found to have significant renal impairment. Epithelioid granulomata were present in five of eight patients who had renal biopsies and glomerular lesions were present in six. There was close correlation between hypercalcaemia, hyperuricaemia, nephrocalcinosis and creatinine clearance. In one patient, renal sarcoidosis complicated membrano-proliferative glomerulonephritis and one patient died in end-stage renal disease.

Dermatitis herpetiformis: a comparative assessment of skin and bowel abnormality.

We reviewed 18 patients with a clinical diagnosis of dermatitis herpetiformis who were being treated with dapsone and were on an unrestricted diet. Diagnosis was confirmed by finding IgA deposits in the dermal papillae of unaffected skin. Dapsone was discontinued and biopsy of affected skin was carried out when the typical rash reappeared. The biopsy findings were graded according to the severity of the histological changes. Small bowel tissue from each patient was examined and graded by stereo- and routine microscopy. Thirteen specimens (72%) were stereomicroscopically abnormal; all 18 showed villous atrophy, either partial or subtotal; and in 13 (72%) the interepithelial lymphocyte count was increased. No correlation was found between the histological severity of the skin and the small bowel lesions. Seemingly the severity of the skin rash in dermatitis herpetiformis is no guide to the degree of small bowel abnormality.

The cytogenetics of 90 patients with idiopathic mental retardation/malformation syndromes and of 90 normal subjects.

A cytogenetic study, done on randomized coded slides, of 90 patients with idiopathic mental retardation and at least 3 other developmentally independent congenital anomalies and of 90 normal subjects is reported. Audiatorography, Q-banding and C-staining were used in the analysis of chromosomally abnormal cases. Eight patients were found to have chromosome abnormalities. Four had substantial chromosome aberrations that would be expected to cause abnormal phenotype. These were CD165 (46,18q-); CD25 (46,18q+) (partial trisomy of 10q); CD175 (46,4q+) and CD95 (46,mar22). In addition, 4 patients were found to have chromosomal anomalies that could not account for their conditions. Three of these were considered to have heterochromatic variants. Patient CD167 had an 9qh+ chromosome which had been inherited from her mother. Case CD137 had a No. 19 chromosome with additional centric heterochromatin. A similar chromosome was found in her mother, maternal grandmother and 2 of 3 half sibs. In patient CD125 a telocentric No. 13 was found. In addition, CD80 was shown to have an XYY constitution. In the normal subjects, no unbalanced chromosome rearrangements were found. Four persons, however, had minor chromosome anomalies. Three were considered to have heterochromatic variants. These were CD54 (46,22p+); CD149 (46,21p+) and CD19 (46,tel22). One normal subject (CD51) was found to be a balanced t(13q14q) carrier. The translocation chromosome had been inherited from his father.
