摘要:

Two hundred eight patients with confirmed or suspected diethylstilbestrol exposure were examined colposcopically at two separate medical centers. Cervicovaginal ridges were present in 90 (43.3%) and ectopy was found in 188 (90.4%) of the patients. Evidence of vaginal adenosis was present in 122 (58.6%) of the cases. Seventy-four percent of the patients had abnormal colposcopic findings: 15.4% having columnar epithelium on the surface of the vagina and 66% having abnormal transformation zones (white epithelium, punctation, mosaic). Twenty patients (9.6%) were initially identified histologically as having squamous dysplasia. Subsequent review of the histologic material in these cases could document only two cases of significant squamous dysplasia, both severe, the remainder having immature, atypical metaplasia or possibly very mild dysplasia. This finding emphasizes the problems encountered in histologically differentiating squamous neoplasia from the peculiar metaplasia found in these patients, thereby making it difficult to establish whether these patients are at increased risk for the development of squamous neoplasia.

摘要:

We studied the arterial blood gas determinations done on the first hospital day in 14 narcotic addicts with bacterial endocarditis (group 1) and six addicts with other medical complications of narcotic addiction (group 2). The arterial oxygen tension (PaO2) was 67.3 ± 3.3 mm Hg (SEM) in group 1, and 75.0 ± 6.4 mm Hg in group 2, with no statistically significant difference (P< .20) between the groups. The arterial CO2tension (PaCO2), 27.8 ± 1.7 mm Hg, in group 1 was significantly lower (P< .005) than that of group 2, 40.1 ± 3.7 mm Hg. The arterial blood pH, 7.47 ± 0.01 units, in group 1 was significantly higher (P< .025) than that of group 2, 7.36 ± 0.06 pH units. Abnormal blood gas values were found in each of the patients in group 1 with a normal admission chest roentgenogram. Arterial blood gas determinations may be useful in the initial examination of ill narcotic addicts.
