[Maternal mortality in the Rheinische Landesfrauenklinik Wuppertal from 1917 to 1979 (author's transl)].

From 1917 to 1979, the maternal mortality in the Rheinische Landesfrauenklinik Wuppertal has been investigated on the basis of 136084 live births. From 1917 to 1921, it was 10.1% and decreased to 0.16% in the period from 1973 to 1979. The maternal mortality in association with caesarean section, which was 11.8% in the period from 1917 to 1921 with a frequency of caesarean sections of 2.5%, decreased to zero since 1973 with a frequency of 6.3%. A caesarean section preceded more than 50% of the deaths since 1962. Most of the decreased (24.4%) were in the group of 30-34 years of age and 48.3% aged more than 30 years. 51.5% were primiparas and 14.6% of the women were at least para 4's. From 1917 to 1936, infection was the main cause of maternal mortality with 39.6%; from 1957 to 1966, however, thrombo-embolism advanced to the leading cause with 27.3%. Since 1960, 4 of 35 deaths were anaesthetic deaths. During all the examined periods, non-specific reasons of maternal mortality were an important factor with more than 30%.

[The influence of radium therapie on the yeast contamination of the vagina (author's transl)].

Before the beginning of radium therapy a vaginal yeast contamination of 9,7% was found of 113 patients with different genital carcinomas. However, the incidence of vaginal yeast contamination increased suddenly to 30,9% under the contac irradiation therapy with radium. The radiation effect of radium is not sufficient for a "selfsterilisation" of the radium-carrier in the case of yeast contamination. Therefore, a chemic desinfection of the radium-carriers is principly necessary. The significance of radium therapy with respect to vaginal yeast contamination is discussed and the recommendation is made that routine mycological supervision be carried out on all patients with gynaecological carcinomas and appropriate antimycotic therapy initiated where necessary.

[The effect of therapeutic doses of gamma radiation on candida albicans cells in vitro (author's transl)].

The problem of side effects of radiotherapy in genital carcinomas on a concomitant vaginal yeast infection was investigated by subjecting candida albicans cells in vitro to the effects of gamma radiation. Agar plates with a defined number of candida albicans cells were irradiated with the conventional gynaecological sources of radium applicators and tele-cobalt. The experimental incubation of the agar plates showed that the number and growth of the yeast colonies were either completely inhibited or stunted by the effect of the radiation. There were also mutations in the cell morphology, animal pathogenecity and sensitivity to antimycotic drugs. The clinical implications of these results are discussed.

Comparative study of in vitro flow characteristics between a human aortic valve and a designed aortic valve and six corresponding types of prosthetic heart valves.

A model of a pulsatile cardiovascular system is described including an electronic control, a hydraulic driving unit, a volume storage, a peripheral resistance and measuring equipment. Six different artificial heart valves, a designed aortic valve (Aachen pockett valve II) and a human aortic valve have been tested in the outflow position of the pump. Three of them are presently being used in clinical applications. Measurements of pressure and volume flow have been obtained for different frequencies n, pump volumes Vp and time ratios between pressure and suction phase. From the experimental results a comparative evaluation was deducted for different working conditions. In comparison to natural human aortic valve (NK) large volume flow is verified by the Aachen pocket valve II (AT), the Gott-Dagget value (GD), the Starr-Edwards valve (SE) and the Lillehei-Kaster valve (LK). The Gott-Daggett valve has the smallest back flow volume. The Smeloff-Cutter and in particular the Wada-Cutter valve have the largest regurgitation. This is to be expected since the Cutter valves are purposely so designed that they do not close tightly in order to avoid blood sedimentation. The human aortic valve, the Gott-Daggett valve and the Aachen pocket valve demonstrate the most favourable opening-closing characteristics. The human aortic valve achieves a negligible pressure loss, followed by the Björk-Shiley and the Lillehei-Kaster valve.

[Torsion of pregnant uterus--a case report].

The 29 year old woman with a caesarian section 5 years before was hospitalized in the 23 rd gestational week bleeding by a placenta praevia totalis and was intravenously tocolized. In the 26 nd gestational week a caesaran re-section was necessary because of heavy acute abdominal symptoms. The uterus presented torquated for 180 degrees to right. The male child (720 g, pH 7.22) died the next night by extreme immaturity. The mother was discharged after 8 days without complications.

Candidosis of the prostate: a rare form of endomycosis.

The third case of a culturally and histologically proven candidosis of the prostate in the world literature available to us is reported. Autopsy of a 59-year-old man with metastasizing bronchial carcinoma as predisposing primary disease revealed a local candidosis of the prostate in the left lobe of the prostate, without evidence of a Candida sepsis. Parallel and different aspects in comparison with the other two cases are described.

Immunological investigations in vaginal mycoses.

In 42 women with chronically recurrent and 20 women with acute Candida albicans vulvovaginitis, as well as 14 women with Candida glabrata vaginitis, the following investigations were carried out: determination of protein content and secretory immunoglobulin A (sIgA) in the cervicovaginal secretion by a self-modified ELISA technique; determination of immunocells and cellbound IgA in the cervicovaginal secretion by immunofluorescence and nephelometric analysis of IgA in the serum. The results were compared with those of 77 pre-menopausal non-pregnant women with or without intake of anti-ovulants, 17 healthy pregnant women and four hysterectomised pre-menopausal women. Due to inflammation, women with acute and chronically recurrent Candida albicans vulvovaginitis had a higher protein content in the cervicovaginal secretion than healthy women. However, the content of secretory IgA was not increased but even slightly decreased in chronic cases. The number of macrophages and granulocytes in the vaginal content was not increased compared with healthy patients. In only a few cases was IgA detected on yeast cells and in the cervicovaginal secretion by fluorescence microscopy. In chronically-relapsing vaginal candidosis, the frequency of the serotype B of C. albicans was strikingly high. Women with Candida glabrata vaginitis showed lower values of secretory sIgA in the vaginal secretion compared with healthy patients as well as women with vaginitis caused by C. albicans. However, like healthy women, they had normal protein values in the cervicovaginal secretion and also lower values of IgA in the serum compared with women of C. albicans vulvovaginitis patients. Macrophages and granulocytes were demonstrable in the cervicovaginal secretion just as in healthy persons. Women with C. glabrata vaginitis showed a more conspicuous, although not a significantly more frequent, binding of IgA to budding cells demonstrated by fluorescence microscopy than women with C. albicans.
