An objective structured biostatistics examination: a pilot study based on computer-assisted evaluation for undergraduates

We designed and evaluated an objective structured biostatistics examination (OSBE) on a trial basis to determine whether it was feasible for formative or summative assessment. At Ataturk University, we have a seminar system for curriculum for every cohort of all five years undergraduate education. Each seminar consists of an integrated system for different subjects, every year three to six seminars that meet for six to eight weeks, and at the end of each seminar term we conduct an examination as a formative assessment. In 2010, 201 students took the OSBE, and in 2011, 211 students took the same examination at the end of a seminar that had biostatistics as one module. The examination was conducted in four groups and we examined two groups together. Each group had to complete 5 stations in each row therefore we had two parallel lines with different instructions to be followed, thus we simultaneously examined 10 students in these two parallel lines. The students were invited after the examination to receive feedback from the examiners and provide their reflections. There was a significant (P=0.004) difference between male and female scores in the 2010 students, but no gender difference was found in 2011. The comparison among the parallel lines and among the four groups showed that two groups, A and B, did not show a significant difference (P>0.05) in either class. Nonetheless, among the four groups, there was a significant difference in both 2010 (P=0.001) and 2011 (P=0.001). The inter-rater reliability coefficient was 0.60. Overall, the students were satisfied with the testing method; however, they felt some stress. The overall experience of the OSBE was useful in terms of learning, as well as for assessment.

Prevalence of Blood Brotherhood among High School Students in Erzurum and the Effect of Peer-led Education on this Practice

OBJECTIVE This study aimed to assess the prevalence of blood brotherhood (BB) in Erzurum, Turkey and to observe the effect of education interventions on this risky cultural behavior. MATERIALS AND METHODS This study was designed as a cross-sectional intervention, based on minor interventions through a peer-led awareness campaign regarding the transfer of blood-borne diseases through BB rites. This study was conducted from February through May 2007 at 29 high schools in Erzurum. RESULTS The study population was 53.8% (n=1,522) males and 46.2% (n=1,307) females. The proportion of the students who have participated in BB rituals was 24.1% (n=558). There was a statistically significant link between BB and a history of having Hepatitis B Virus (HBV) infection, family history of HBV and male gender (p<0.05). After the structured peer-led education the intention to participate in BB rituals decreased from 30.0% to 20.6% (p<0.001). CONCLUSION The prevention of BB rituals, which can result in the transfer of blood-borne diseases, requires urgent public awareness campaigns led by healthcare professionals.

Management of Legg–Calve–Perthes disease with acupuncture: a case report

Legg–Calve–Perthes disease (LCPD) is a rare temporary hip joint deformity mostly effecting young children from 4–10 years of age. It involves mainly the head of the femur, which softens and breaks down due to interruption of blood supply (avascular necrosis). We report a case of LCPD that was treated late and had a poor prognosis, but improved significantly during a prolonged course of acupuncture. A 12-year-old boy reported to an orthopaedic clinic in 2006 with limping and was diagnosed with LCPD. Surgeons applied orthosis without improvement and decided to perform surgery in 2008. However, the parents declined the surgical option and took the boy to an acupuncture clinic the same year. Needle acupuncture for 20 min and laser acupuncture locally on the hip joint area for 5 min were applied. After 30 sessions of acupuncture, the boy started to improve clinically. Imaging studies showed that new bone cells started to develop in the femoral head. After 130 sessions in 2010 the radiographic appearance showed almost 90% improvement, and after 196 sessions, in August 2012, he was fully recovered. Needle acupuncture treatment combined with laser acupuncture may be an option for the management of LCPD.
