[Measles and mumps antibody concentrations in newborns and their mothers--follow up first year of life].

BACKGROUND: During the last twenty years the incidence of measles and mumps decreased after introduction of vaccinations in the industrial nations. The vaccination rate of the population in Germany lies currently under the required elimination rate. The epidemiological situation has changed altogether. The illness age has on the one hand moved up, teenager and adult suffer more frequent these so-called children's diseases with an increased complication rate. On the other hand illness cases in infancy seeming to increase. It was aim of this study to examinate the current serological situation for measles and mumps antibody status in women in childbed and their healthy newborns at birth time and during the first seven to nine life months. PATIENTS AND METHOD: 237 healthy newborns, born in 1999 in Bochum, West-Germany and their mothers were included. The mothers were asked if and when they did suffer from measles and mumps or were questioned to active vaccinations against these diseases. Immediately antepartal from all mothers was taken a venous blood sample. Immediately postpartal from all newborn childs umbilical cord blood was taken and again a blood sample in the age of six to eight months. In the serum tests the measle and mumps IgG antibody concentrations were examined quantitatively with ELISA methods. In cases with negative or borderline positive values the plaque neutralization test was also used for measuring of the measle antibodies. CONCLUSIONS: Between the maternal and neonatal titers results the knownly positive correlation. Maternal lending immunity against measle and mumps lasts more less into infancy as generally suspected. An earlier first active immunization against measles and mumps could be discussed. The strict realisation of the present vaccinating recommendations should be operated as a matter of priority to lead to the desired measles and mumps eradication.

Bacterial vaginosis is not important in the etiology of cervical neoplasia: a survey on women with dyskaryotic smears.

BACKGROUND AND OBJECTIVES: It has been suggested that bacterial vaginosis may play a role in the etiology of cervical neoplasia. The authors analyzed the prevalence, risk factors, and impact on histologic changes of bacterial vaginosis in women with cytological abnormalities of the uterine cervix. METHODS: Two-hundred-eighty women with dyskaryotic smears were surveyed. Using a questionnaire, data were obtained on smoking habits and sexual history. Bacterial vaginosis was the diagnosis if the vaginal discharge produced a fishy odor upon alkalinization and if clue cells were seen in the wet smear. Cervical scrapes were analyzed for the presence of human papillomavirus DNA, and cervical tissue specimens were analyzed for the presence and severity of (intraepithelial) neoplasia and the proliferation rate (mitotic index) of the lesion. Chlamydia trachomatis was identified by culture of an endocervical swab. RESULTS: Bacterial vaginosis was found in 56 (20%) out of the 280 women. The presence of bacterial vaginosis was significantly associated with the number of cigarettes smoked per day, age at first sexual intercourse, the lifetime number of sexual partners, and current Chlamydia trachomatis infection. The number of cigarettes currently smoked per day and the lifetime number of sexual partners were independent significant risk factors for the presence of bacterial vaginosis. There was no relation between the presence of bacterial vaginosis and the human papillomavirus infection. Bacterial vaginosis did not influence the severity of the (intraepithelial) neoplasia or the mitotic index. CONCLUSION: In women with dyskaryotic cervical smears, the prevalence of bacterial vaginosis did not seem to be increased, and bacterial vaginosis did not influence the histologic changes. Therefore, bacterial vaginosis is unlikely to be important in the etiology of cervical neoplasia, despite the similarity between its epidemiologic features and those of cervical human papillomavirus infection and cervical neoplasia.

Carotid surgery under locoregional anaesthesia. Description of technique and results of our first 100 consecutive operations.

In a 28-month-period 100 consecutive carotid operations were performed on 91 patients under locoregional anaesthesia. The indications were 37 TIAs, 16 recovered strokes, 12 cases presenting with amaurosis fugax, eight with vertigo and 27 patients with severe but still asymptomatic stenosis. In 20 cases a shunt had to be used. Twice a transient neurological syndrome developed, two strokes occurred. One stroke patient died in the postoperative course. Carotid surgery under locoregional anaesthesia seems to be a safe method with advantages for the patient and the surgeon.
