Evaluation of a teaching hospital necropsy service.

The information returned to the hospital clinician after a necropsy was investigated in a series of 1000 patients. It was found that specific clinical queries were answered in 83% of cases, that the necropsy corrected the major clinical diagnosis in 36% of cases, and that 29% of cases were used for undergraduate or postgraduate teaching. The results demonstrate the continuing value of the necropsy as an investigative and educative procedure.

Histometry of lymphoid infiltrate in the thyroid of primary thyrotoxicosis patients. Relation of extent of thyroiditis to preoperative drug treatment and postoperative hypothyroidism.

The thyroids of primary thyrotoxicosis patients prepared for partial thyroidectomy with propranolol contained much more lymphoid infiltrate than those prepared with carbimazole. No relation was found between the extent of lymphoid infiltrate in the thyroid and the development of postoperative hypothyroidism either between or within the two drug treatment groups. This study has shown that the extent of thyroid infiltrate should not be used as the major factor in predicting hypothyroidism after subtotal thyroidectomy for primary thyrotoxicosis.

The influence of preoperative drug treatment on the histological appearances and in vitro 131I uptake of human hyperplastic thyroid gland.

The specimen of thyroid resected at partial thyroidectomy from 103 patients with primary thyrotoxicosis was studied with histometric and organ culture techniques. Twenty-seven patients had been prepared for operation with propranolol and seventy-six with carbimazole: all received Lugol's iodine for 10 days before operation. The resected specimen and deduced total thyroid weight was greater in the patients prepared with carbimazole. There was no absolute qualitative histopathological difference in the appearance of the glands of the two groups of patients, but histometry showed that the volume percentage of colloid and total gland colloid weight was significantly greater in the patients prepared with carbimazole: the volume percentage of epithelial cells and the total gland epithelial cell weight was similar in the two groups. The iodide concentrating capacity per g wet weight thyroid tissue or per unit volume of colloid did not differ significantly between the two groups. However, the iodide concentration capacity per unit volume of epithelial cells was significantly higher in the carbimazole prepared patients than in those prepared with propranolol.
