Impotence in scleroderma.

Hormonal, neurologic, and vascular factors affecting potency were evaluated in 10 men with scleroderma and in 10 age-matched men with rheumatoid arthritis. Impotence was reported by 6 of the patients with scleroderma and none with rheumatoid arthritis. Studies of serum testosterone, free testosterone index, follicle-stimulating hormone, luteinizing hormone, prolactin, estradiol, thyroxine, and thyrotropin did not show a hormonal basis for impotence in any patient.

Male hypogonadism and scleroderma.

Two male patients with scleroderma and hypogonadism are described. One patient had Klinefelter's syndrome. The second had normal testosterone but elevated gonadotrophins.

Demonstration of axonal projections of neurons in the rat hippocampus and subiculum by intracellular injection of HRP.

Hippocampal formation neurons of rat were injected intracellularly with horseradish peroxidase in order to trace intrinsic and extrinsic axonal projections. CA3 pyramids (n = 9) projected axons rostrally toward the fimbria, one or more Schafer collaterals toward CA1, and in two cases fibers that crossed the hippocampal commissure. Pyramids of CA1 (n = 5) projected axons to the alveus where they proceeded caudally toward the subiculum.

Anorexia Nervosa in twins: case report and review.

The cases of a pair of monozygotic female twins simultaneously concordant for anorexia nervosa area reported. About half of the previously reported cases of anorexia nervosa in twins are concordant; however, interpretation of the clinical data reviewed is difficult because diagnostic criteria are not always clear. Clinical parallels between anorexia nervosa and folie à deux are discussed.
