Zinc deficiency in surgical patients: a clinical study.

Four stressed surgical patients who had different diseases are presented. They had dermatitis associated with low serum zinc levels but were not on total parenteral nutrition. The range of serum zinc varied between 25 and 56 mu/dl when first seen. All but one had hypoalbuminemia and anemia; one patient had diarrhea. When measured, other microelements were normal. These patients were thought to have zinc deficiency and all their symptoms responded favorably to oral zinc and nutritional support. A highlight of previous reported cases of zinc deficiency is presented along with a brief review of the subject. Acute stress including major operations will decrease the serum zinc level temporarily. Zinc deficiency may be the result of chronic zinc depletion caused by other conditions. Chronic leg ulcers are associated with low serum zinc levels and might precipitate zinc selectively. A zinc supplement will help in the healing of these ulcers and wounds in general. The possibility of an interrelationship of zinc and other microelements is raised but is not clear.

[Present and future choices of vaginal drug dosage forms. I. Classical forms].

The anatomy and physiology of vagina play a major role in the formulation of vaginal products. In this review, many classical dosage forms (tablets, suppositories, creams, gels, foams...), used either for local or systemic treatment are described and discussed. Formulation and essay are briefly reviewed. But emphasis is layed on the problems associated with the administration of these dosage forms, their advantages with regard to other vaginal products and the use of these products as contraceptive devices.

[Present and future choice of pharmaceutical forms for intravaginal administration. II. Barrier systems and vaginal rings].

In part I of this review, various vaginal products for local and systemic treatment have been described and discussed. Part II is reserved to other intravaginal contraceptive systems. Some devices as diaphragms, sponges, ... have a mechanical contraceptive advantage associated or not with a spermicidal activity and can or cannot protect against venereal diseases. Other devices like intravaginal rings allow a long-acting and controlled release of contraceptive hormones and it is quite possible that they replace orale contraceptive dosage forms. Various approaches in designs, safety, effectiveness, inconvenience and advantages are discussed.
