Background: In the last decade the diagnosis of celiac disease has increasingly been made in adults.

Objectives: To determine disease prevalence (including silent and potential disease) in this population group.

Methods: We performed serologic screening of celiac disease in a representative and homogenous sample of a young adult general population in Israel, namely, 18 year old military conscripts, in 2003. Serologic screening was performed on serum samples randomly obtained from 850 healthy recruits (male/female = 1.1). Immunoglobulin A anti-tissue transglutaminase was determined by enzyme-linked immunosorbent assay. In cases of IgA[1] deficiency, IgG anti-endomysial antibodies were determined. A small intestinal biopsy was offered to all patients with positive serology.

Results: The prevalence of overt CD[2] diagnosed prior to recruitment was 0.12% (0.1% in men and 0.14% in women). The overall prevalence based on positive serology was 1.1%. Six of nine subjects with positive serology agreed to undergo endoscopy and intestinal biopsies. In all cases, biopsies were compatible with celiac disease (five biopsies were graded as Marsh 3a and one as Marsh 3b). One subject previously reporting irritable bowel-like symptoms was diagnosed with overt atypical CD. The prevalence of overt CD diagnosed by screening was 0.12%. The ratio of overt to silent CD was 1:8. No cases of potential disease were encountered.

Conclusions: Our findings suggest that CD is highly prevalent in the young adult population in Israel. Serologic screening for CD is a reliable and simple method for diagnosing this disease before symptoms or complications develop.

Background: Complementary medicine is gaining popularity, yet medical school curricula usually ignore it.

Objectives: To determine whether senior medical students are interested in learning principles of complementary or alternative medicine, to check their degree of familiarity with it, and to suggest a format for such studies in the medical curriculum.

Methods: Senior medical students (n = 117) were surveyed by an anonymous questionnaire.

Results: Seventy-nine percent of the senior medical students were interested in studying complementary or alternative medicine in medical school, and 65% were interested in applying these techniques to treat patients. Eighty-seven percent of students were familiar with some techniques of complementary medicine.

Conclusions: Senior medical students are interested in studying complementary and alternative medicine in medical school and in applying these techniques in practice.
 

Background: Prevention of cigarette smoking is an important issue in public health policy. Since most adult smokers began smoking in childhood, understanding behavor­ial factors associated with smoking initiation would contribute to smoking initiation programs. Health-related behavior may vary between different ethnic groups.

Objectives: To determine the prevalence of smoking among Jewish and Arab adolescents in Jerusalem, and whether there are differences in smoking initiation between the two ethnic groups.

Methods: We carried out a cross-sectional survey of all students in the 6th to 11th grades (age range 11-17 years) of a Jewish school and an Arab school in the Jerusalem area, using an anonymous self-completion questionnaire. A total of 791 questionnaires was analyzed, 479 from the Jewish students and 312 from the Arab students.

Results: The lowest prevalence of smoking was found among Arab female students and the highest among Jewish female students (9% vs. 41%, P<O.OO1). The prevalence of smoking among Jewish and Arab males was similar. More Arab female students smoked than their mothers. Peer pressure seemed to be a more important factor among Jewish students.

Conclusions: This study demonstrated the presence of ethnic differences in smoking prevalence and the reasons for smoking among adolescents in Israel. These results suggest the need for specific smoking prevention policies for different ethnic groups.
