Giardiasis is the most common protozoan parasite diagnosed in the pathology departments of Health Centres in the State of Bahrain. In 1983 all records of stool parasitology examinations in one of the largest medical centre (Salmaniya Medical Center) were studied, a total of 9664 records. The incidence of Giardia lamblia was 4% (386 cases) of the total records, about 21% of all infected persons by parasites. 100 persons from the above records were serologically examined by CIT with 93% positive results. The incidence of Giardia lamblia amongst the families of infected persons of the 386 cases was higher than the families of non-infected persons.

Menstruation is a phenomenon unique to the females. It is clear from the study findings that majority of the girls were having correct knowledge about menstruation. Regarding the practices, only 10 girls were using boiled, and dried cloth as menstrual absorbent. Though almost all 64 girls received advice regarding menstrual hygiene from different sources, some of their practices were unhygienic. This shows that the mothers of these girls were lacking of right knowledge and the same thing was transferred to their off springs. Before bringing any change in menstrual practices they should be educated about the facts of menstruation and its physiological implications. The girls should be educated about the significance of menstruation and development of secondary sexual characteristics, selection of a sanitary menstrual absorbent and its proper disposal. This can be achieved through educational television programmes, school nurses/Health personnel, compulsory sex education in school curriculum and knowledgeable parents, so that she does not develop psychological upset and the received education would indirectly wipe away the age old wrong ideas and make her to feel free to discuss menstrual matters without any inhibitions.
