RESUMO
UNLABELLED: Communication has been identified as one of the core clinical skills for all health care providers, but it is especially important for primary health care disciplines. Findings suggest the need for more attention to communication skills in continued physician education. This work aims at evaluating the effect of a communication skills training program on physicians' knowledge, attitude and self efficacy related to communication. In this pretest- posttest intervention study, a three-day, 18-hour training program was developed and implemented. The teaching method was learner-centered and includes theoretical information, practical applications and attitude change. A self administered questionnaire was used to evaluate the program. The results showed significant improvement in physicians' knowledge about communication where those having good knowledge increased from 13.1% before the intervention to 82% after the intervention. Physicians reported significantly higher confidence levels in their ability to build rapport with patients, counsel patients for smoking cessation and medication adherence after the intervention. CONCLUSION: Overall, in this study we found that training in communication skills improves clinicians' knowledge, changes some negative attitudes and enhances assessment of physicians' own ability to perform specific communication tasks.
RESUMO
BACKGROUND: Acute viral hepatitis is less frequent in Egypt than serum antibody levels suggest. Because acute viral hepatitis has a wide clinical spectrum, we tested the hypothesis that many cases are undetected because of mild illness caused by initial, early-childhood exposure to hepatitis viruses. METHODS: During active case detection among 20,000 inhabitants of rural villages in Egypt, we screened 1715 symptomatic patients for serum alanine aminotransferase (ALT) levels. Viral hepatitis markers were tested in 47 subjects who had ALT levels that were least twice the normal level. RESULTS: Of the 47 individuals tested, 4 children aged 3-5 years had immunoglobulin M (IgM) antibodies to hepatitis A virus (anti-HAV IgM). One also had a possible false-positive result to a test for IgM antibodies to hepatitis E virus. None had serological evidence of acute hepatitis B virus (HBV) infection or hepatitis C virus (HCV) infection. However, 33 of the remaining 43 had active HCV infection, having both antibodies to HCV (anti-HCV) and HCV RNA. Four others anti-HCV without HCV RNA, and 2 others had seroconversion to anti-HCV during follow-up. Two patients who were positive for hepatitis B surface antigen had chronic HBV infection. Only 3 with elevated ALT levels had no evidence of acute or chronic infections with known hepatitis viruses. Immunoglobulin G antibodies to hepatitis E virus was detected in 40 patients. CONCLUSION: Active surveillance covering approximately 50,000 person-years detected only 4 cases of acute HAV infection. Almost all persons with mild symptoms and elevated ALT levels had serological evidence of chronic viral hepatitis, most often associated with HCV. Many of these cases were probably "flare-ups" of HCV infection or incidental illness in patients with chronic HCV infection, but some could have been caused by difficult-to-confirm initial HCV infections. Although serological evidence for exposures was highly prevalent, hepatitis viruses seldom caused acute viral hepatitis in these communities.

BACKGROUND: Hypertension is a significant predictor for cardiovascular diseases and is the most important preventable or modifiable cause of morbidity and mortality from these diseases. Undiagnosed cases of hypertension and poor control are important factors in controlling hypertension worldwide, including Oman. AIM OF THE STUDY: The aim of this study was to identify the important risk factors and predictors of the state of unawareness of the presence of hypertension, as well as the risk factors for poor control of blood pressure, among hypertensive patients. MATERIALS AND METHODS: Data from Oman World Health Survey (OWHS), 2008, were used in this study. The OWHS adopted a multistage stratified cluster sampling to select study participants. An interview questionnaire was used to collect data related to risk factors. Other parameters included blood pressure, anthropometric and biochemical measurements. RESULTS: The prevalence of hypertension in Oman was estimated to be 41.5%. Of those who were hypertensive, three-quarters of them (75.7%) were unaware of being hypertensive and 65.5% of them had inadequately controlled hypertension. Male sex, higher wealth, and paying fewer visits to health facilities were found associated with high proportions of unawareness and high proportion of uncontrolled hypertension. CONCLUSION AND RECOMMENDATIONS: The study highlights high levels of unawareness of being hypertensive and high proportion of uncontrolled hypertension in Oman that need to be considered when developing health policies and strategies. Intersectorial collaborative and innovative strategies that focus on improving awareness, detection, and control of hypertension should be considered, especially with attention to young adults and men.

BACKGROUND: The diagnosis of carpal tunnel syndrome (CTS) continues to be neurophysiologically and clinically controversial. Earlier data concluding that the higher prevalence of persons with symptoms suggestive of CTS but without evidence of median mononeuropathy highlights the need for a better understanding of the underlying pathophysiology and natural history of CTS to provide a less empirical foundation for diagnosis and clinical management. OBJECTIVE: To examine the relationship between the clinical manifestations of CTS with the outcome of the diagnostic tools (nerve conduction tests and ultrasonography), and its implication for clinical practice. METHODS: Two-hundred and thirty-two patients (69 male and 163 female, ages ranging between 20 and 91 years) with CTS manifestations and 182 controls were included in this study. Diagnosis of CTS was based on the American Academy of Neurology clinical diagnostic criteria. All patients and controls completed a patient oriented questionnaire, were subjected to clinical testing for provocative tests for carpal tunnel syndrome (Tinel's, Phalen's, Reverse Phalen's and carpal tunnel compression tests), blood check for secondary causes of carpal tunnel syndrome, nerve conduction testing as well ultrasonographic assessment of the carpal tunnel and median nerve. RESULTS: One-hundred and seventy-seven out of 232 (76.3%) had abnormal nerve conduction studies. Forearm symptoms and tenosynovitis confirmed by US examination were found in 51.3% of cases. No significant difference was found on comparing anthropometric measures in the affected hands to the control group hands. A higher prevalence of positive Phalen's and CT compression were found in patients suffering from tenosynovitis regardless of their nerve conduction study results. Sensitivity of Tinel's, Phalen's, Reverse Phalen's and carpal tunnel compression tests was higher for the diagnosis of tenosynovitis than for the diagnosis of CTS (Tinel, 46% vs. 30%; Phalen's, 92% vs. 47%; Reverse Phalen's, 75% vs. 42%; carpal tunnel compression test, 95% vs. 46%). Similarly, higher specificity of these tests was found with tenosynovitis than CTS. CONCLUSION: The results of this study revealed that Tinel's, Phalen's, Reverse Phalen's and carpal tunnel compression tests are more sensitive, as well as being specific tests for the diagnosis of tenosynovitis of the flexor muscles of the hand, rather than being specific tests for carpal tunnel syndrome and can be used as an indicator for medical management of the condition.
