Background. Vietnam has a low age-standardized incidence of breast cancer, but the incidence is rising rapidly with economic development. We report data from a matched case-control study of risk factors for breast cancer in the largest cancer hospital in Vietnam. Methods. 492 incident breast cancer cases unselected for family history or age at diagnosis and 1306 control women age 25–75 were recruited from the National Cancer Hospital (BVK), Hanoi. Structured interviews were conducted and pathology data was centrally reported at the National Cancer Hospital of Vietnam, in Hanoi. Results. Our analysis included 294 matched pairs. Mean age at diagnosis was 46.7 years. Lower mean parity, older age at first parity, increasing weight and BMI at age 18, and increasing BMI at diagnosis were positively correlated with breast cancer cases compared to controls. Age at first menarche and duration of breastfeeding were not statistically different between cases and controls. Conclusions. In this study we demonstrate that breast cancer in Vietnam is associated with some but not all of the published risk factors from Western populations. Our data is consistent with other studies of breast cancer in Asian populations.

We report a case of a 72-year-old woman who experienced postictal episodes of trismus lasting several minutes on 6 occasions during a series of 18 episodes of electroconvulsive therapy (ECT). There was no clear relationship between the development of trismus and any medications used during the treatments. The patient had no adverse outcomes or discomfort, but the development of trismus can put patients at significant risk.

tomography images using the Synapse Vincent (Fuji Medical Systems, Tokyo, Japan) and HoloEyesXR (Holoeyes, Tokyo, Japan) software. Following completion of each training protocol, participants completed an anonymous questionnaire composed of 0-10 scale and openended questions assessing the utility of the training.RESULTS: 15 participants were enrolled in this study and they all completed the questionnaires. The median (range) age of the participants was 21 (21-23) years. The 3D organ model projection significantly improved assessment scores regarding the following 7 elements; anatomical acquisition, renal hilum inspection, self-efficacy to detect the kidney, self-efficacy to conduct renal US, ease of kidney detection, learning effect of the training, and recommendation to other students (p<0.05 for all). The most frequent answer to the open-ended question regarding why they thought MR technology was useful for US training was, "contribution to understanding the positional relationship between the abdominal organs." (13/15, 87%).CONCLUSIONS: Holographic 3D organ model projection from a wearable MR computer facilitates renal US training of medical students.
