The effect of ampicillin on oral contraceptive effectiveness.

The effectiveness of oral contraceptives with concomitant use of ampicillin has been questioned. Eleven volunteer subjects were studied during 2 consecutive menstrual cycles; they were given Demulen with placebo or ampicillin during each of the cycles. Serum estradiol (E2), progesterone (P4), luteinizing hormone (LH), and follicle-stimulating hormone (FSH) were evaluated on days 13 and 19 of each cycle. Testosterone-binding globulin (TeBG) capacity and ferning of cervical mucus were evaluated on day 13 of each cycle. Subjective symptoms were recorded. All cycles appeared to be anovulatory. Steroid suppression was present in 10 of 11 patients during both cycles. Estrogen-dependent TeBG was not affected by ampicillin. It is possible that cervical mucus ferning was improved by concurrent ampicillin administration. Ampicillin appears unlikely to diminish the effectiveness of the oral contraceptive studied.

Role of oral contraceptive in atherosclerosis.

The possibility that risk of a atherosclerosis complication increases with oral contraceptive use was examined by studying the effect of oral pill containing 0.067 mg menstranol and 0.667 mg ehtynodiol diacetate/kg body weight on the metabolism of lipids in female rats fed a hypercholesterolemic diet for three months. Experimental group clearly exhibited higher levels of triglycerides and cholesterol in plasma and tissues, increase in aorta observed to be two folds. Increased hepatic cholesterogenesis was noted with treatment of oral contraceptive as indicated by higher activity of HMG-CoA reductase. Activity of lipoprotein lipase of extrahepatic tissue was depressed in experimental group. Activity of plasma LCAT, an enzyme involved in the transport of cholesterol from tissues, was also lower with treatment of oral contraceptive. However, activity of malic enzyme and glucose-6-phosphate dehydrogenase enhanced considerably with administration of oral pill. The increase in plasma and aortic cholesterol levels, increase in LDL+VLDL cholesterol and considerable decrease in HDL cholesterol in animals treated with oral contraceptives and fed with atherogenic diet, indicates that prolonged administration of oral pill may predispose towards atherosclerosis.

Massive intestinal infarction in young women: complication of use of oral contraceptives?

Massive intestinal infarction due to occlusion of the celiac, superior mesenteric and inferior mesenteric arteries occurred in two young women, one of who subsequently died. Both were smokers. They had ingested oral contraceptives for 5 and 8 years, respectively, but this therapy could not be proven to be a causative factor in their ischemic bowel disease; although such an association is uncommon, it should be considered in young women with abdominal pain.

[An unusual case of intercalary type of limb abnormalities].

Authors report about a case of total lack of middle phalanxes on the 3d and 4th fingers and a hypoplasia of the surrounding phalanges on the left hand. This is the first report on this type of intercalary type in congenital limb deficiency group. They call attention to one of the so far not sufficiently emphasized hazard of previous periconceptional oral contraceptive use. If there is not enough time left for the total regeneration after the discontinuation of contraceptives, such kind of malformation may develop in the fetus due to the insufficiency of fetal-placental circulation.

Menometrorrhagia in an oral contraceptive user.

Endometrial carcinoma is the most frequent malignancy of the female reproductive tract, and irregular vaginal bleeding is the most common presenting symptom. Endometrial carcinoma is found most commonly among postmenopausal women and is associated with obesity, nulliparity, and anovulation. Oral contraceptive (OC) use and tobacco smoking have been reported to protect against endometrial carcinoma. Irregular vaginal bleeding is a common side effect of OC therapy. We report the case of an obese, premenopausal nulliparous woman with normal menses who developed menometrorrhagia and was then found to have endometrial carcinoma despite her youth and her use of both tobacco and combination OC.

Ambiguous genitalia in XX male children: report of two infants.

Two infants with ambiguous genitalia were recognized to have the XX male syndrome. Although most XX males have normal penile development, a review of the reported cases showed that eight of the 14 affected children, diagnosed before age 15 years, had penile abnormalities, most commonly hypospadias and/or chordee. This syndrome should be considered in children with incomplete genital differentiation. The available indirect evidence suggests that deficient testosterone production by the fetal testes accounts for the genital ambiguity. Although no explanation has been established for the presence of testes in the apparent absence of the Y chromosome, studies of the X-linked Xg blood group in XX males demonstrate a high frequency of unusual inheritance patterns. This implies that the abnormality in the transmission of maleness in affected families may also be X-related rather than autosomal.
