[Acute epididymitis and antibiotherapy. Measurement of the epididymal diffusion of pefloxacin].

Acute epididymitis is a common infection in the young sexually active adult. Etiologically, the organisms most frequently found are Chlamydia trachomatis, Neisseria gonorrhea and gram negative bacilli. Pefloxacin is a novel quinolone whose antibacterial spectrum and bactericidal activity allow it to be considered for use in the treatment of orchitis and epididymitis Prior to clinical study the authors investigated the degree of epididymal diffusion of Pefloxacin. Ten subjects underwent extraction of an epididymal sample by direct access to the epididymis through a transverse scrotal incision under peridural anesthesia. Three days before surgery, Pefloxacin was administrated at the rate of 400 mg every 12 hours by the oral route. On the day of the operation, the subject receive a 400 mg infusion over one hour, 2 hours before epididymal biopsy. Blood specimens were also extracted. Pefloxacin assays were performed by HPLC following a method derived from that of Montay. The trough concentration of Pefloxacin inhibiting 90% of sensitive strains (MIC 90) is less than or equal to 2 micro-g/ml. The majority of sensitive organisms have minimum bactericidal concentrations equal to twice the MIC 90. The epididymal concentrations that the authors measured are situated at values of 8.15 to 21.80 miro-g/g tissue (mean 13.44). These data allow the use of Pefloxacin to be considered an option in the treatment of epididymitis.

[Lutenyl and menstrual disorders. A hospital study].

The efficacy of nomegestrol acetate in the treatment of menstrual cycle disorders and dysfunctional uterine bleedings was confirmed on 66 cases in this study conducted by three hospital departments. The study also confirmed the perfect clinical tolerance of nomegestrol acetate. One knows that the same is not true with Nortestosterone derivatives which were used up to now in these indications.

[Death in utero of a twin during the 2d and 3d trimester of pregnancy].

The study of a series of 9 cases of monofetal death during the last trimester of a twin pregnancy, permits to emphasize the relative frequency of this accident (7.14% in our series, markedly higher than those noted in the literature). An early diagnosis, essentially on ultrasonography, of monofetal death, enables monitoring of the mother and the surviving fetus for whom there is a non negligible risk. It is often necessary to deliver this fetus as soon as it is mature. Systematic and repeated clinical and ultrasonographic monitoring of any twin pregnancy during the third trimester ensures, in a large number of cases, prophylaxis of this accident.

[Can zinc deficiency in the mother be responsible for the occurrence of spina bifida aperta in the fetus?].

The occurrence in the fetus of closure defects of the neural tube and especially spina bifida aperta (SBA) has been related, by some authors, to nutritional deficiencies of the mother, in addition to well-known genetic factors: a folic acid deficiency and more recently a zinc deficiency have been evoked. The retrospective study of 23 couples mother/newborn selected from the presence of a SBA in the child, and 14 reference couples, shows that the mothers of children with SBA have a zinc blood level lower than that of the reference group; this result is confirmed by the alkaline phosphatases and zinc enzymes which are markedly decreased. Measurement of the incorporation of radioactive zinc in the skin fibroblasts shows, in case of SBA, in the mother, an increased incorporation rate, and in the newborn a decrease of that rate in relation to the reference group. We believe that the results of our study which confirm those from other authors, demonstrate that the administration of zinc during pregnancy is at least as important as the administration of folic acid to prevent recurrence of neurulation abnormalities.

[An attempt at classification of the vaginal arteries. Functional and surgical implications].

It has been possible to attempt to classify the vaginal arteries after studying 10 specimens of total contents of the pelvis removed at autopsy. The classical descriptions are confirmed except for these features: The longitudinal vaginal artery supplies the anterior and inferior part of the vagina and probably also the bladder. The middle haemorrhoidal artery supplies, as far as we can see, mainaly the posterior portion of the vagina. Finally, in a last section, we discuss some surgical and functional implications arising from these deductions.

Effects of a multivitamin mineral supplement on zinc and copper status during pregnancy.

The effect of a multivitamin-mineral supplement was investigated during pregnancy according to a double-blind protocol by determining zinc and copper in maternal plasma, mononuclear and polynuclear zinc and copper at the third, sixth, eighth, and ninth months of gestation. The subjects were supplemented from the first trimester until delivery. A significant decrease was observed in plasma zinc that varied from 11.5 mumol/L to 10.8 mumol/L in the supplemented group (n = 29) and from 11 mumol/L to 10 mumol/L in the placebo group (n = 33) at 3 and 9 mo of gestation, respectively. In contrast, plasma copper levels increased in a way depending upon the stage of gestation in both groups: from 24.7 to 28.2 mumol/L in the treated group and from 24.9 to 30.9 mumol/L in the placebo group at 3 and 9 mo of gestation, respectively, but the difference was only significant in the placebo group. No difference between groups was observed in mononuclear and polynuclear zinc or copper levels. These trace elements were also determined in cord blood at delivery. There were no statistically significant differences in zinc and copper concentration found in placebo group and supplemented group. Finally, the beneficial effect of supplementation on muscular cramps and appearance of vergetures was noted.

[Effects of a sequential combination of estradiol valerate and cyproterone acetate on the functional properties of the arterial wall in menopausal women].

Several studies have shown that estrogen replacement therapy protects postmenopausal women against coronary artery disease. This protective effect has been ascribed to the hormone's effect on serum lipids, as well as a direct action on the vascular wall. Concurrent administration of a progestin to protect women from the risk of endometrial hyperplasia may alter the protective effects of estrogen. The aim of this study was to assess the evolution of the endothelial function in postmenopausal women given a sequential combination of oral 2 mg estradiol valerate for 11 days, followed by 2 mg estradiol valerate associated with 1 mg cyproterone acetate for ten days (Climène). Each 21-day sequence was followed by a seven-day treatment-free interval. The women received a three-month treatment course. Thirty-one healthy postmenopausal women participated in the study (median age: 51 years; range: 45-59 years). Flow-mediated dilatation (FMD), a reflection of endothelium-dependent vasomotor function, increased from 8.47% at baseline (range: 4.57-11.02%) to 9.64% (range: 7.07-13.12%) at the end of the first treatment cycle; i.e., a 15% increase over baseline (P < 0.0001). FMD further increased after three treatment cycles to 10.59% (range: 8.09-15.22%); i.e., a 28.6% increase over baseline (P < 0.0001). FMD at the end of the first combined sequence or after the 11 days of estradiol only were similar (delta = 0.25%; range: -2.31-5.81%; not significant). In conclusion, in postmenopausal women, a three-month sequential treatment combining estradiol valerate and estradiol valerate plus cyproterone acetate (Climène) has beneficial effects on endothelial function as demonstrated by the evolution of the FMD. There was no decrease in the effect of estradiol on FMD when cyproterone acetate was added to estradiol.

[Listeria monocytogenes nosocomial infection in the maternity ward].

Nosocomial infection with Listeria monocytogenes 4b occurred in January 1990 in a maternity hospital in Grenoble. The 3 patients involved were born within a 24 hour-interval. The premature newborn responsible for contamination was asymptomatic. Two other newborns without any perinatal infectious risk presented with meningitis, one on the 5th day of life in the maternity hospital, the other one on the 11th day while already at home. The 3 strains of Listeria had the same serovar and lysovar. Epidemiologic investigations led to suspect a contamination in the delivery room and during the care of the children. Strict respect of hygiene orders is imperative to avoid nosocomial infections.

[Maternal-child transmission of Chlamydia trachomatis. A prospective inquiry in 168 pregnant women].

A prospective study was performed in 168 pregnant women in order to evaluate the frequency of perinatal transmission of Chlamydia trachomatis and to measure its effects on the child's health during his first 3 months of life. The micro-organism was detected by an immunoenzymatic method specific to Chlamydia antigens, and microimmunofluorescence was used for serological testing. Cervical smears taken at the end of pregnancy were positive in 3 women (1.7 per cent), while the sera of 37 women were positive for Chlamydia trachomatis. Altogether, 26.8 per cent of the women explored had had a contact with the micro-organism. Conjunctival smears taken from 1 month old infants were all negative, but 4 infants (out of 126) had positive nasal smears. The mothers of 2 of these had been exposed to the bacterium, but all 4 mothers had negative cervical smears. Antibody titres in 3-month old infants were 1.2 dilution on average below those found in the mothers. Women exposed to Chlamydia trachomatis are frequently unmarried; their pregnancies tend to shorter than normally, and their infants have more frequent episodes of rhinitis. These peculiarities are insufficiently pronounced to single out a population at risk that might benefit from detection of the bacterium.
