Background: Acupuncture and public interest in this modality have increased over recent years in Israel and throughout the western world.

Objectives: To compare the knowledge and attitudes of physicians to medical students with regard to acupuncture.

Methods: An anonymous questionnaire was completed by internists and medical students at the Soroka Medical Center.

Results: There were 122 respondents in all, 57 of them women (46.7%). The study sample included 40 physicians (33%), 39 fifth year medical students (32%) and 43 second year medical students (35%). The majority of participants (93.4%) had never received training in acupuncture and 84.4% had never undergone acupuncture therapy themselves. In these variables there were no significant differences between the physicians and the students. The participants’ level of knowledge of acupuncture was very low, with 40% unable to answer even one question (of eight) correctly. Despite the poor level of knowledge and the lack of personal exposure to acupuncture, 90 participants (74%) believed that acupuncture has more than a placebo effect, and 57 (42%) believed it was important to include acupuncture in medical education. There were no statistically significant differences in the attitudes of physicians and medical students to acupuncture.

Conclusions: The level of knowledge and exposure of physicians and medical students to acupuncture is low. However, both groups have relatively positive attitudes to this modality as an acceptable treatment for health problems and were open to its inclusion in the medical school curriculum.

Background: Genes that confer mild or moderate susceptibility to breast cancer may be involved in the pathogenesis of sporadic breast cancer, modifying the phenotypic expression of mutant BRCA1/BRCA2 alleles. An attractive candidate is the insulin-like growth factor I, a known mitogen to mammary ductal cells in vivo and in vitro, whose serum levels were reportedly elevated in breast cancer patients.

Objective: To evaluate the contribution of the IGF-1 gene polymorphism to breast cancer risk by genotyping for a polymorphic allele size in breast cancer patients and controls.

Methods: We analyzed allele size distribution of the polymorphic CA repeat upstream of the IGF-I gene in 412 Israeli Jewish women: 268 women with breast cancer (212-sporadic and 56 carriers of either a BRCA1:or BRCA2 mutation), and 144 controls. Genotyping was accomplished by radioactive polymerase chain reaction of the relevant genomic region and size fractionation on polyacrylamide gels with subsequent auloradiography,

Results: Among women with breast cancer, with or without BRCA germline mutations, 196 and 198 basepair alleles were present in 4.7% (25/536 alleles), compared with 9% (26/288) controls (P = 0.02). This difference was more pronounced and significant in the non-Ashkenazi population. Conversely, the smaller size allele (176 bp) was present in the breast cancer group only {3/536, 0.6%).

Conclusions: The IGF-I polymorphism may serve as a marker for breast cancer risk in the general Jewish population, in particular non-Ashkenazi Jews, but extension and confirmation of these preliminary data are needed.
