Androgen Therapy in an "excessively" tall boy.

An "excessively" tall, early pubertal boy was treated with androgen for a period of 33 months. Sexual development and fusion of epiphyses was accelerated with achievement of shorter stature than that predicted prior to therapy. Testicular size did not appear to be impaired by the therapy. Androgen administration in this young boy appeared to be effective in shortening the eventual adult stature.

Studies of the development of congenital anomalies in rats. III. Effects of inhibition of mitochondrial energy systems on embryonic development.

Pregnant rats were treated with various inhibitors of mitochondrial oxidative energy metabolism and with lowered oxygen tension, and the embryo fetuses examined for the occurrence of congenital malformations and for changes in enzymatic activities. Treatment with all agents tested resulted in the production of skeletal anomalies. Sodium phenobarbital was the most teratogenic of the drugs tested and produced a high incidence of malformations which included cleft palate, tail anomalies, spinal retroflexion, domed head, and facial hypoplasia. Diphenylhydantoin produced a low incidence of syndactyly and oligodactyly. In addition to its effects on fetal growth and development chloramphenicol appeared to interfere with implantation. Tissue preparations from embryos exposed to sodium phenobarbital and chloramphenicol showed markedly lowered levels of DPNH oxidase activity. Cytochrome oxidase activity was also markedly lowered in the preparations from chloramphenicol-exposed embryos. Enzyme activities in preparations from embryos exposed to malonate and diphenylhydantoin appeared unaffected, although the drugs are strong inhibitors of electron transport in vitro; the lack of apparent effect may be due to the fact that both drugs do not bind to the enzyme preparations and were diluted 100- to 200-fold during preparation and assay of the tissue homogenates.

Some aspects of carbohydrate metabolism in Prader-Willi syndrome.

Three patients with Prader-Willi syndrome are reported. The subjects presented chemical diabetes mellitus. All patients were hypersentsiive to exogenous insulin and they showed poor adrenal medullary response to hypoglycaemics. It was postulated that the poor adrenal medullary response to the insulin injection may be a contributing factor in the excessive hypoglycaemic response, and that the diabetes mellitus observed in the patients could be due to inactivation of endogenous insulin.

Epilepsy and abnormal calcium metabolism in institutionalized mentally retarded patients.

A group of epileptic and nonepileptic patients from an institution for mentally retarded persons was surveyed for roentgenographic and biochemical abnormalities of calcium metabolism. Osteoporosis, hypocalcemia, and increased alkaline phosphatase were found to be significantly increased in incidence in the epileptic group. The only significant difference among the osteoporotic and nonosteoportic epileptic patients was the increase fo the alkaline phosphatase in the former. Ambulation did not appear to influence the significance of the above parameters.
