Solitary Fibrous Tumor of the Female Pelvis – Clues to the Radiological Diagnosis
Solitary fibrous tumors were initially described in the pleural cavity and they were thought to have mesothelial origin. Nowadays, these tumors are known to have origin in the mesenchymal cells and they are ubiquitous with both pleural and extrapleural distribution. There are many extrapleural localizations, being the pelvis one of the rarest and the most challenging to diagnose. Usually, solitary fibrous tumors are clinically insidious and manifest as a slow-growing large tumor. At imaging, these tumors have different characteristics, and computed tomography and magnetic resonance play an important role in their diagnosis. Solitary fibrous tumors appear as heterogeneous enhancement on contrast-enhanced computed tomography, intermediate signal on T1-weighted images, hypointense on T2-weightes images and show intense heterogeneous enhancement in dynamic sequences. When they appear in the female pelvis, it is essential to recognize their radiological characteristics, in order to differentiate it from others tumors, like pure stromal ovarian tumors or Brenner tumors. This study reviews the female pelvis solitary fibrous tumors’ imaging findings and its differential characteristics from more common tumors, by describing illustrative confirmed cases.
Awareness and the use of evidence-based medicine resources among physicians
Amjad Alhelo, Bashar Samara
Aim: to evaluate awareness and the use of evidence-based medicine resources among physicians in Jordan.
Method: A cross-sectional study by internet was performed among 517 doctors who were responsive from a total of 717 doctors, a total of 72.1% response rate. Doctors from all specialties were contacted from a Facebook group called doctors café in Jordan. A questionnaire was given to each one of them to measure their awareness and use of Evidence based database.
Result: From 517 physicians 377 they are using evidenced based resources frequently, and 91 using resources but not frequently and 49 not using evidence-based resources. The resource that was mostly used by the doctors was PubMed, followed by other resources such as Up to date, National Guideline Clearinghouse, Medscape, BMJ best practice, e-books and other online journals for published papers. The Cochrane Library was surprisingly not so familiar amongst physicians.
Conclusion: There is good awareness about EBM among physicians in Jordan, and that benefits health care in Jordan.
Effectiveness of self-instructional module on knowledge regarding Attention Deficit Hyperactive Disorder among primary school teachers in selected schools of Gangtok Sikkim

Attention Deficit Hyperactive Disorder is a common behavioural disorder that affects about 10% of school age children. About 7% children worldwide have Attention Deficit Hyperactive Disorder. In rural India population, the prevalence of Attention Deficit Hyperactive Disorder is 3.66%. The main aim of the study was to find out the effectiveness of self-instructional module on Attention Deficit Hyperactive Disorder. The investigators adopted a pre-experimental research design among seven selected schools through simple random sampling.A total of 80 primary school teachers were selected using the purposive sampling technique. Self-instructional module and structured knowledge questionnaire was prepared and sent for validation. Pretesting and reliability was done and found reliable(r = 0.8). Firstly, pretest session was conducted using structured knowledge questionnaire to assess the knowledge of primary school teachers on Attention Deficit Hyperactive Disorder. Self- instructional module(SIM’s) was administered 4 days after the pretest session. After 14 days of SIM’s distribution, posttest was conducted to assess the effectiveness of self-instructional module. The findings reveal that majority 60% of primary school teachers have average knowledge in the pre-test and 86.25% had good knowledge in the post-test. The calculated paired ‘t’ test value ‘t = 11.259’ was found to be statistically significant at p<0.05 level. The study concluded that educational material in the form of self-instructional module helped the teachers to improve their knowledge on Attention Deficit Hyperactive Disorder. The gained in the knowledge from the Self-instructional module will help them to identify and manage children with Attention Deficit Hyperactive Disorder in future.
