[Additional treatment with Esberitox N in patients with chemo-radiotherapy treatment of advanced breast cancer].

A study was made at random on 70 female patients with advanced mamma carcinoma to find out whether an additional treatment with Esberitox N prevents or diminishes the sideeffects of a combined chemo-radiation therapy. As it could not be excluded that the efficacy of Esberitox N on previous affliction by haematotoxic therapy would probably differ, the study was made on various groups of risk. The parameter to form an opinion were either the peripheral hematosis or the appearance of infections. It turned out, however, that Esberitox N proved only effective if there was only a minor damage of the bonemarrow. The efficacy seems to promote the recuperation of the haemapoetic system. There was no significant frequency of infections by the additional Esberitox N treatment, yet in tendency favourably influenced.

[Supplementary treatment with Esberitox of female patients undergoing curative adjuvant irradiation following breast cancer].

1. The study was supposed to investigate a possible prevention or reduction of the toxicity of radiotherapy by an additional treatment with Esberitox. This question arose when performing an investigation about the effect of Esberitox in a combined chemo-radiotherapy. Whereas the latter induces above all a systemic damage to the hemopoietic system, radiotherapy is a regional noxa. 2. The present prospective, randomized study was conducted with 50 patients submitted to curative adjuvant irradiation following surgery for mammary carcinoma. The radiotherapy was performed in the same way in all patients with irradiations of the thoracic wall and the regional lymph nodes. Two groups were built by randomization. The study group received an additional treatment with Esberitox, the control group did not receive an additional treatment. 3. As a result, no protective influence of Esberitox could be demonstrated. The parameters investigated were the peripheral blood count (leucocytes, granulocytes, lymphocytes, monocytes, thrombocytes, hemoglobin, hematocrit) and the incidence of infections. 4. This result diverging from literature is discussed. It is probably affected by volume and extension of the injury induced by a hematotoxic noxa and furthermore by the ability of regeneration. If this ability is exhausted, the protective effect of Esberitox can act no longer. Therefore the essential factor seems to be the duration of exposure to the noxa. Esberitox was effective in case of a short toxicity, it was ineffective in case of prolonged toxicity, if the treatment continuity (noxa) was not broken up by some regeneration intervals. The radiotherapy studied in this trial had a duration of 50 days, and its effect was that of a longterm injury.

Assay of disaturated phosphatidylcholine in amniotic fluid as a test of fetal lung maturity: experience with 2000 analyses.

We determined concentrations of disaturated phosphatidylcholine (DSPC) in nearly 2000 amniotic fluid samples obtained either transabdominally or as vaginal pools. Here we report our comparison of these DSPC values with the lecithin/sphingomyelin (L/S) ratios for amniotic fluid samples obtained from diabetic and nondiabetic pregnancies and also between transabdominally or vaginally collected samples uncontaminated by blood or meconium. DSPC measurement is at least as good as the L/S ratio in predicting the absence of respiratory distress syndrome. DSPC concentrations were, however, lower in diabetic than in nondiabetic pregnancies, supporting the hypothesis that DSPC synthesis may be impaired in fetuses of diabetic mothers. Visually uncontaminated samples collected transabdominally or vaginally, when grouped according to length of gestation, have similar DSPC values but different L/S ratios. Thus, even in the absence of blood or meconium, DSPC may be a more useful test than the L/S ratio for vaginally pooled samples.

Intrauterine aspiration of a large fetal ovarian cyst.

Most large series of neonatal ovarian cysts are limited to those diagnosed in the newborn period. Eight cases of fetal ovarian cysts diagnosed prenatally by ultrasound have been reported, only one of which was aspirated in utero. Reported is the youngest fetus to undergo in utero aspiration of an ovarian cyst to reduce the risk of secondary pulmonary hypoplasia.

Attitudinal and demographic correlates of food supplementation practices.

Attitudinal and demographic correlates to food supplement use were ascertained for 689 adults residing in seven Western states. Of the 689, 372 (54%) were food supplement users and 317 (46%) were non-users. The only attitudinal variable significantly (p less than .001) related to the practice of food supplementation was the belief that vitamin C could cure and prevent a cold. More users than non-users agreed with the statement that "vitamin C can both prevent and cure a cold." Demographic variables found to be significantly (p less than .05) related to food supplement use included education, marital status, home type, employment status, and population of town/city in which the respondent resided. Food supplement users tended to be living together without marriage, never married, or divorced and living in town houses or "other" types of dwellings. More users than non-users resided in communities with populations of 2,500 or in communities with populations of 10,000 to 49,999.
