Reduced creatinine clearance in primary osteoporosis in women.

We determined the relationship between bone mass and age, anthropometric variables, and serum and urine biochemical variables in 77 normal white women and 37 women with primary osteoporosis, 25 of whom had one or more vertebral compression fractures. Skeletal status was assessed by radiography of the hands with measurement of combined cortical thickness of the second metacarpal bones (CCT) or measurement of radial and lumbar bone density, or by both methods. Radial bone mineral content (RBMC) was measured by single-photon absorptiometry (SPA) and lumbar bone mineral density by dual-photon absorptiometry (DPA).

Bone mass is related to creatinine clearance in normal elderly women.

We determined the relationship between bone mass and age, anthropometric variables, creatinine clearance (Ccr), and serum and urine biochemical variables in 77 normal white women (aged 41-86, mean = 67) living in their own homes. A total of 74 women were postmenopausal. Skeletal status was assessed in all subjects by x-rays of the hand with measurement of the mean combined cortical thickness (CCT) of the second metacarpal bones.

Osteopenia, pathological fractures, and increased urinary calcium excretion in schizophrenic patients with polydipsia.

Ten male chronic schizophrenic patients with polydipsia and 10 nonpolydipsic controls, matched for gender, diagnosis, duration of illness, age, and race, were studied by dual- and single-photon absorptiometry to estimate bone density of the lumbar spine and radius and by 24-hr urine collections to estimate urinary electrolyte excretion. Bone density was normal in the control group, but was abnormally low in the polydipsic group, which had a markedly increased incidence of fractures. Electrolyte excretion was normal in the control group and in the polydipsic group when water intake was restricted to normal amounts; increased urinary sodium and calcium excretion occurred in proportion to polydipsia.

Management of total ureteral loss after kidney transplantation.

Loss of the ureter after transplantation is uncommon and is difficult to manage. A Boari flap can be used to replace the ureter. The authors describe two patients with total ureteral loss.

The protean manifestations of renal vein thrombosis in the adult.

We reviewed 8 cases of renal vein thrombosis, 4 of which were detected at autopsy, 1 by laparotomy and the remaining 3 by venography. In 4 cases malignancy also was found and in 2 membranous glomerulonephritis was noted. In 1 patient the thrombosis occurred in a solitary kidney, while it was bilateral in 3.

Sympathetic activity in the proximal urethra in patients with urinary obstruction.

The effect of 10 mg. phentolamine intravenously on the urethral pressure profile was studied in male and female patients with lower urinary tract obstruction. A significant decrease of pressure occurred along the whole length of the urethra in both sexes, including the peak pressure zone in the male patient.

Idiopathic retroperitoneal fibrosis with protein-losing enteropathy and duodenal obstruction successfully treated with corticosteroids.

A 40-year-old carpenter presented with vomiting due to duodenal obstruction. On further investigation he had partial obstruction of both ureters and occlusion of the inferior vena cava. At laparotomy a large retroperitoneal mass of fibrous tissue was found, which extended into the root of the mesentery of the small intestine and partially occluded the duodenum.
