Unprofessional behavior is the single most common cause for disciplinary action against medical students in their clinical rotations, residents, and clinical practitioners. The Association of American Medical Colleges (AAMC) and the National Board of Medical Examiners (NBME) will like to see professionalism taught and evaluated across medical school. Gross Anatomy, with cadaver laboratory dissection, is in a unique position to preside over a rich number of activities where behaviors of professionalism can be taught, practiced, and rewarded. Such activities will be comparable to the behaviors of professionalism taught in clinical rotations. This article highlights the essential involvement and tools that can be used to teach, evaluate, and promote behaviors of professionalism accessible in the laboratory with cadaver dissection.

During 2003 to 2004 school period, 2070 students filled out the Global School Health Survey (GSHS)--a school based cross-sectional self-administered survey that explores, among other areas, sexual behavior. Students who responded that ever had intercourse, males 27% and females 3.8%; by grade, males 18.2% (7th) and 37.6 % (9th), and females 1.9% (7th) and 6.2% (9th). The group who had intercourse, 54.9% males and 25.3% females had it by age 12; 59% males and 78.6% females were sexually active in the past 12 months; 59.2% males and 43.2% females used condom in the last intercourse; and 48.3% males and 21.5% females has 2 or more sexual partners in their life. A disparity is present in school-based information, >63% for AIDS and &l...

Paraffin sections, 40 microns thick, of the basal ganglia from autopsied patients over the age of 45, were stained with PAS. A three-dimensional microscope, R400 (edge) was used to evaluate the structure of the blood vessels. Six patterns of the tortuous profiles were identified: simple kink, loop, knot, tangle, coil, and wave, and well as their combinations. Tortuous arterioles in the basal ganglia were present both in control group and status lacunaris cases. However, statistical Student's t-test analysis revealed a significant increment in the number of microfields containing tortuous terminal arterioles in the status lacunaris group (mean 7.50 +/- 4.62) versus the control group (mean 2.92 +...

Methods: The Global School-based Student Health Survey (GSHS), State of Lara, Venezuela (GSHS-Lara) is a school-based surveillance system. It comprises a repeated, cross-sectional, self-administered survey drawn from a representative sample of 7th to 9th grade students, performed in the school years 2003-2004 (GSHS-Lara 2004) and 2007-2008 (GSHS-Lara 2008). It explores, among other things, a general violence indicator such as school absenteeism due to feeling unsafe at school or on the way to or from school for any reason; and more specific indicators of violence such as robbery, bullying, physical fights and use of weapons, as well as exposure to lectures on how to prevent violence. Results are given in terms of prevalence percentage. Results: Absenteeism doubled between the two study periods (10.8 % to 20.8%). The...

Health policy decision-making on suicidal behavior needs reliable information on the prevalence of suicidal ideation (SI) and its associated risk factors to produce health promotion and prevention programs. METHODS The Global School Health Survey is a self-administered survey done on a random probabilistic sample among students of the 7th, 8th, and 9th grades in the Lara State, Venezuela, school period 2003 to 2004. Point prevalence of SI and associated factors were included and the odds (OR) of having SI was calculated given selected factors. RESULTS Two-thousand seventy (2070) respondents, of which 13.5 % reported having SI in the last 12 months, and in females more than males (14.6% vs. 11.7%). The OR for SI, according to an associated risk factor, were among (a) females: age > or = 14 years (2.2), worries (3.42), loneliness (8.8), ever had sexual intercourse (5.58), alcohol (8.43) and...

Amyloid deposits are rare findings that have been reported in pituitary neoplasms. We report a case of a 48-year old man with a diagnosis of prolactinoma with extensive amyloid deposition. To our knowledge, this is the first case of amyloid in a pituitary neoplasm at our institution.

This article reviews trends in sexual behavior among students of the 7 th to 9 th grades using data from the Global School-based Student Health Survey, a school based, cross-sectional, self-administered survey done on a representative sample of students in Lara State, Venezuela (GSHS-Lara) in years 2004 and 2008. Overall, 14.1% (2004) and 16.7% (2008) reported ever having had sexual intercourse. Among students who had sexual intercourse, a-54.9% (2004) vs. 47.2% (2008) of males had their first experience at age ≤12, while for females 25.3% vs. 8.3%; b-only 59.2% (2004) and 59.9% (2008) of males used condoms in his/her last intercourse, while for females 43.2% vs. 58.1%; c-48.3% (2004) and 58.3% (2008) of males had ≥2 lifetime sexual partners while for females 21.5% vs. 23.7%. Exposure to lectures on HIV/AIDS at school was low (<75%), while for sexual abuse it was even lower (<40%). In the period studied, there was a high prevalence of risky sexual behavior despite improvement in exposure to information at school. These results call for the evaluation of programs aimed at risk reduction in sexual behavior.
