A randomized double blind study of two oral contraceptives.

To study the question of whether one brand of oral contraceptives may be as acceptable as another for use of publicly-assisted family planning programs, a double blind study of two well-known brands, Ovral and Norinyl, was undertaken in Costa Rica and Trinidad. The pills were randomly assigned to 1,200 women. Common side effects - nausea, dizziness, vomiting, headaches - were associated with both Norinyl and Ovral. Differences in event rates for these conditions were much more marked by country than by the pill used. Ovral was associated with increases in skin problems, notably chloasma, in Cost Rica. A higher percentage of women using Norinyl reported intermenstrual bleeding and spotting in both countries. In Costa Rica continuation rates for Norinyl were adversely affected by this. With these exceptions there appear to be no important differences between the brands that would affect their use in family planning programs.

[Elemental diet and external fistulae of, the digestive system].

An elemental diet is a food which provides the basic needs in calories, proteins, vitamins and minerals with two advantages: it is predigested and leaves minimal or no residue to provide bulk. The care of 20 patients, with an elemental diet, presenting 20 external fistulas (75 per cent with low output and 25 per cent with high output) succeeded to obtain a spontaneous healing in 75 per cent of the cases, and an improvement of the general conditions of 15 per cent of the patients who were operated on because of fistula persistency. The death rate was 10 per cent. We think that the elemental diet is a useful tool in the treatment of external fistulas of patients who have preserved their bowel movements and an output smaller than 500 ml. in 24 hrs.

[Candida infections and their evolution in patients receiving parenteral feeding].

Parenteral nutrition has completely modified the prognosis in a variety of illnesses of digestive tract. The method is not devoid of complications, and septicemias, particularly those originated by fungii of the Candida species, have been informed to occur with an alarming frequency of up to 23%. The patient on parenteral nutrition is an ideal prey for this kind of infection, but if the technic and the metabolic control are brought down considerably. In 30 patients of the Department of Gastroenterology at the Hospital General, Centro Médico Nacional, Instituto Mexicano del Seguro Social, we have studied the frequency and evolution of Candida infections, detected before or during the treatment with parenteral nutrition to know the influence of the method on this type of host-parasite relationship. In the initial cultures 60% of the patients develop Candida in one or several regions; percentage increased to 63.3% at the end of 15 days and decreased spontaneously to 33% at the end of the treatment on the 30 patients we did not observe a septicemia due to Candida. We conclude that parenteral nutrition, while correcting the nutritional state of the patient, with a good technic, favors the spontaneous withdrawal of the fungii, without the necessary specific treatment.
