RESUMO
The relationship between neonatal tetanus (NT) on one hand, and maternal tetanus immunization and other prenatal and natal practices on the other hand, was examined in a case-control study done at San Lazaro Hospital (SLH) in Manila from late 1990 to mid 1991. Included as cases were 54 patients diagnosed as NT on the basis of WHO criteria, and 50 controls who were patients 0-4 months of age, hospitalized at SLH during the study period and with no past history of tetanus. The result showed that the following were statistically associated with the risk of NT: home delivery (OR = 30.5); delivered by a traditional birth attendant (OR = 5.2); use of instrument other than scissors to cut the cord (OR = 19.3); traditional birth attendant who dressed the cord (OR = 12.7); and having less than two doses of tetanus toxoid (OR = 15.3). The need to intensify prenatal tetanus immunization, health education of the mothers as well as the training of birth attendants is evident from this study if NT has to be prevented.

Ascaris lumbricoides worm populations were studied from 150 Filipino children (0-14 years) dewormed with pyrantel pamoate (Combantrin) or oxantel-pyrantel pamoate (Quantrel). Populations were classified according to intensity of infection: very light, light, moderate or heavy. A total of 2072 adult worms were sexed (939 males and 1133 females) and weighed. Descriptive statistics on the weights obtained from each sex were derived and one-way ANOVA was performed to compare the mean weights among the 4 intensity classes. Linear regression analysis (individual worm weight versus total worm burden) was also employed to equalize the possible influence of host factors. Statistical analysis revealed that mean weights of both sexes were significantly different and decreased as worm burden increased. This strongly suggests that the "crowding effect" phenomenon may also apply to Ascaris lumbricoides, and not only to tapeworms, as reported in the literature.

A comparative study of Trichomonas vaginalis prevalence among Filipino women is presented herein. A total of 288 women randomly drawn from various sources, including Social Hygiene clinics, Health Centers, and Family Planning Centers in the Metropolitan Manila Area were examined for T. vaginalis. Nineteen or (6.8%) were found positive either by wet mount or stained smear methods. Prevalence was significantly higher among the group of single than married women and five times higher among the waitress/hostess group than in the housewife/other group. Infection was related to parity and is significantly higher among nulliparous women. Likewise, a significant relationship was observed between prevalence of infection and gravidity. Prevalence decreases with increasing gravidity. No relationship in prevalence was observed between the use and non-use of contraceptives, and the method of contraceptive used. There was no significant association between the presence of the parasite and symptoms.
