The first pelvic examination and common gynecological problems in adolescent girls.

The first pelvic examination is a rite of passage into American womanhood. Indicators and special considerations for performing a pelvic examination for a teenaged female are reviewed. Factors in the history, physical examination, and laboratory evaluation of the adolescent are presented. The sequence of pubertal events before, during, and after menarche is discussed so that menstrual disorders are presented in the context of normal development. The author presents a synthesis of her approach to caring for adolescents with a review of current literature and resources available to health professionals.

A comparison of accuracy and estimated cost of methods for home blood glucose monitoring.

Venous serum glucose concentrations determined by a laboratory hexokinase technique were compared over a wide range of glucose concentrations with concentrations of capillary blood glucose determined by three reflectance meter techniques currently available in the United States (Eyetone and Dextrometer, Ames Company; StatTek, Bio-Dynamics BMC) and by visual interpretation of reagent strips (Chemstrip bG, Bio-Dynamics BMC). The Chemstrip bG reagent strip was read by patients, nurses, and a physician. In all cases, there was an excellent correlation between laboratory serum glucose concentrations and reflectance meter blood glucose determinations (r = 0.90-0.94, P less than 0.0001) or visual interpretation of Chemstrip bG (r = 0.85-0.92, P less than 0.0001). Chemstrip bG appears to be the least expensive method of glucose measurement. This method offers additional advantages in not requiring a reflectance meter, which needs frequent recalibration and other ancillary equipment for blood glucose determination.

Pulmonary contusion: CT vs plain radiograms.

In experimentally induced pulmonary contusions, CT (n = 27) and chest X-ray (n = 24) findings were compared with the findings at autopsy. Twenty-seven of 27 (100%) pulmonary contusions were visible by CT immediately after trauma compared with 9 of 24 (37.5%) in the chest X-ray. After 30 min follow-up, 18 of 24 (75%) lesions were seen on the plain film. Five of 24 (21%) contusions escaped detection on conventional radiographs. Computed tomography underestimated lesion size in 5 of 60 (8%) measurements, conventional radiographs in 21 of 36 (58%) measurements. Pathological examination never revealed a pulmonary contusion that was not demonstrated by CT. Therefore, pulmonary contusion seems unlikely in a trauma patient with normal pulmonary CT.
