[Q]: Abstract: During a 6-year period, 14 of 898 patients examined at a pediatric electromyographic laboratory had a compressive mononeuropathy. These included five injuries to the peroneal nerve, four to the sciatic nerve, two to the distal radial nerve, and one each to the deep palmar branch of the ulnar nerve, the musculocutaneous nerve, and the long thoracic nerve. A potentially preventable mechanism was identified in 9 of the 14 patients, including prolonged posture in three of the four sciatic and two of the peroneal neuropathies. Four other mononeuropathies were secondary to pressure from an orthopedic appliance or procedure (one injury to the musculocutaneous nerve, one to the long thoracic nerve, two to the peroneal nerve).

[Q]: Abstract: Human granulosa-luteal cell production of cyclic adenosine 3',5'-monophosphate (cAMP) and progesterone (P) were studied in response to purified human chorionic gonadotropin (hCG) in cultured cells from hyperstimulated follicles of in vitro fertilized patients. The hCG injection given to the patients 36 hours before laparoscopy caused partial desensitization of adenylate cyclase of these cells to gonadotropins. Preincubation of the cells in hormone free medium for 2 to 3 days significantly increased their cAMP responsiveness to hCG. P production was stimulated initially by hCG and showed no desensitization. In the cells preincubated for 72 hours without hCG, a subsequent stimulus of 50 ng/ml of hCG elicited maximal cAMP response, whereas 1 ng/ml of hCG was sufficient to bring about maximal P secretion. Time-course studies indicated that maximal cAMP response to hCG was obtained in 1 to 3 hours. Both basal and hCG-stimulated P accumulation continued to rise for up to 24 hours. Preincubation of granulosa-luteal cells from hyperstimulated follicles improves the cells' cAMP responsiveness to hCG, whereas P response remains unaltered.

[Q]: Abstract: The total cobalt and nickel concentration of 11 brands of Asian cement ranged from 8.1 to 14.2 micrograms/g and 14.9 to 28.5 micrograms/g, respectively. These metals exist mainly as insoluble salts; the water-soluble concentration of cobalt and nickel in the cements ranged from 0.39 to 0.65 micrograms/g and from 0-1.2 micrograms/g, respectively. 1.5% (4/272) of construction workers in a prefabrication construction factory had cobalt sensitivity. All had allergic contact dermatitis from chromate in cement. No worker had isolated cobalt sensitivity and cement dermatitis. It appeared that sensitization to cobalt in cement occurs only secondarily to an existing cement dermatitis. 1.8% (5/272) workers had nickel sensitivity: 2 with allergic contact dermatitis to nickel in their watches, 2 were asymptomatic and 1 had allergic contact dermatitis to chromate and cobalt in cement. The low prevalence of cobalt and nickel sensitivity from cement was probably related to the low concentration of soluble cobalt and nickel salts in the cement. However, these insoluble salts can form soluble complexes with body fluids on eczematous skin and sensitize the skin.
