ABSTRACT
To determine the purified protein derivative conversion rate among Lebanese children we followed a cohort of 1236 students, ages 5-14 years, enrolled in 25 public schools in Beirut. All cases received an intradermal injection of purified protein derivative in 1992 and one year later. Test administration was done using standard techniques and results were read by the same physician 48-72 hours later. Demographic information was also obtained on the enrolled students. The majority of children identified belonged to a low socioeconomic class. The one year conversion rate was 1.4%. This underscores the urgent need for preventive programs.

BACKGROUND: Although imperforate hymen occurs in approximately 0.1% of female newborns, familial occurrence of imperforate hymen has been reported only once. CASES: We report two families in which imperforate hymen was diagnosed in three siblings of each family. One family is described in detail; the patients were two postmenarchal young women and one premenarchal girl. CONCLUSION: Imperforate hymen usually occurs sporadically but can be familial. We advise screening all female newborns and children for vaginal patency, especially family members of an affected child. Identification of other families with a similar problem might point to a specific mode of inheritance.
