Urinary creatinine excretion and lean body mass.

In a group of 34 adult and child subjects a high correlation (r = 0.988) was found between lean body mass, as determined by potassium-40 counting, and urinary creatinine excretion. The effect of technical errors was reduced by averaging the results of two or three 40K assays on each subject, and by making consecutive 3-day collections of urine. It appears that one can make a reasonable estimate of lean body mass from urinary creatinine excretion.

Testosterone-estradiol-binding globulin in patients with Turner's syndrome: effects of estrogens and acute growth hormone administration.

The TeBG activity of plasma from patients with Turner's syndrome was measured quantitatively using polyacrylamide gel electrophoresis. Human growth hormone administration did not significantly change the plasma TeBG levels. However, oral replacement therapy with estrogens elevated plasma TeBG within 3 days; after 9 days these levels reached a maximum of three- to four-fold greater than that observed at a time prior to therapy.

Postadrenalectomy pituitary adenoma (Nelson's syndrome) in childhood: clinical and roentgenologic detection.

Following total adrenalectomy in Cushing's syndrome associated with adrenal hyperplasia, but not with adrenal adenoma or malignancy, elements of the pituitary may be stimulated to grow rapidly and even aggressively. There is strong evidence to support the idea that there is a pre-existing tumor in many, if not all, of these cases. In some, the tumor may be too small to deform the sella turcica. After adrenalectomy, these patients should be observed carefully and frequently for hyperpigmentation, visual field defects, and sella turcica enlargement.

Effects of starvation in infancy (pyloric stenosis) on subsequent learning abilities.

The model of starvation in this study was the medical condition of congenital hypertrophic pyloric stenosis. Pyloric stenosis involves a period of brief starvation in early infancy, is unrelated to socioeconomic conditions, and is easily correctable. A number of specific learning abilities together with the general adjustment of 50 subjects, 5 to 14 years old, who had PS were studied and compared to those of 44 siblings and 50 matched controls. Learning ability was negatively correlated with the degree of severity of the starvation. Starvation resulting in reduction of more than 10% of the expected body weight in infancy was associated with poorer learning abilities, especially those involving short-term memory and attention.
