Radiographic measurements of the normal adult foot.

Various radiographic measurements of the normal adult foot have been reported in both early and recent literature; however, a complete description of radiographic quantitative data has yet to be reported. The purpose of this study is to describe the range of the normal foot using standard radiographic techniques that can be applied to the clinical setting. This should provide the data necessary for the accurate interpretation of foot radiographs. This study demonstrates the wide variation in bony relationships of the normal adult foot. When certain recognized criteria of radiographic measurements were evaluated, some were found to be defined as too narrow or inaccurate. Most importantly, because of this wide range, surgical procedures to produce radiographic homogeneity are not indicated. Treatment should be directed specifically toward areas of pain and not radiographic appearance.

Analysis of the effect of ovulatory suppressants on glucose tolerance.

PIP: Glucose tolerance was studied using the standard oral test in 61 patients taking cyclic estrogen-progestin combinations for a period of 3 months to 7 years. 27 women were on cyclic mestranol-norethynodrel in 10 mg doses, 5 were on 5 mg doses, 16 were on cyclic mestranol-ethynodiol diacetate in 1 mg and 12 in 2 mg doses, 1 was on norethindrone. Decreased tolerance was observed in 39% of the study group with 18% having diabetic tolerance curves. Follow-up studies were conducted over a period of 3 to 28 months and variable results were obtained. The mechanism of decreased glucose tolerance is unknown. There is no accurate means of predicting which patient will develop decreased tolerance while on cyclic estrogen-progestin therapy.^ieng
