[Health habits and vaccination status of Lebanese residents: are future doctors applying the rules of prevention?]. / Comportements a risque et statut vaccinal des résidents au Liban: les futurs médecins appliquent-ils les règles de la prévention?

BACKGROUND: There has never been a nationally representative survey of medical students' personal health-related practices, although they are inherently of interest and may affect patient-counseling practices. This study evaluated the health practices and the vaccination status of first year residents working at the academic hospital Hôtel-Dieu de France. METHODS: The medical files of all medicine and surgery residents in their first year of specialization between the years 2005 and 2008 were reviewed. These residents were required to go through a preventive medical visit at the University Center of Family and Community Health. RESULTS: One hundred and nine residents (109) were included in the study; 68 (6239%) were male and 41 (37.61%) were female with a mean age of 26 years. Only 6 residents (5.50%) practiced physical activity according to international guidelines (more than three times a week for more than 30 minutes each time). Most residents (n = 76 ; 69.73%) used to skip one or two meals especially breakfast and as a consequence 30 male (44.11%) and 4 female (9.75%) students were overweight, with a statistical difference between the two sexes (Fisher test, p-value = 0.001). Twenty-eight residents (25.69%) were smokers with a male predominance. Fourteen residents of both genders (12.84%) drank alcohol regularly (> 3 times a week) and 71 (65.14%) had a drink occasionally (once a month or less). Only 25 residents (23%) of the cohort had a complete and up-to-date immunization status. The immunization gap was basically against measles, mumps, rubella (MMR) and diphtheria, tetanus, poliomyelitis (dT Polio). Ninety-nine residents (90.83%) had full immunization against hepatitis B with an adequate response in 78 residents (71.56%). CONCLUSION: This study showed that our residents did not always have a healthy lifestyle especially when it comes to physical activity and eating habits. They also lacked an adequate vaccination. Interventions should take place in order to promote healthy life style and to improve their vaccination status.

Determinants of antibiotic use and throat culture in managing pharyngitis among primary health care physicians in Beirut.

BACKGROUND: Studies have suggested that antibiotics are often inappropriately prescribed for the treatment of pharyngitis despite clinical evidence and international guidelines. This study examined the use of antibiotics by primary health care physicians (PHC) and their reliance on clinical factors in the decision to prescribe throat culture and antibiotics, as advocated by the Centers for Disease Control and Prevention (CDC). METHODS: A questionnaire was completed by 103 PHC physicians randomly selected and working in Beirut, Lebanon. RESULTS: Primary care physicians prescribed antibiotics to 42% of patients with pharyngitis, especially if patients consulted during winter v/s summer (68% v/s 38% ; p < 0.01). The most frequent symptoms and signs leading to antibiotic prescription and to throat culture in pharyngitis were tonsillar exudates, cervical adenopathy and fever. No physician used all the criteria in the score adopted by the CDC to decide on the prescription of antibiotic or throat culture. CONCLUSION: This study showed a high prescription rate of antibiotics and a lack of adherence to clinical guidelines by PHC physicians in the management of pharyngitis. Efforts to help physicians improve their practices should be implemented by the diffusion of international recommendations and the monitoring of practices.

Refractory seizures: Prediction of outcome of surgical intervention based on results from PET-CT, PET-MRI and electroencephaolography.

PURPOSE: The purpose of this article is to evaluate the effectiveness of fluorodeoxyglucose (FDG) positron emission tomography (PET)-computed tomography (CT) and PET-magnetic resonance imaging (MRI) with scalp and intracranial electroencephalogram (EEG) in predicting surgical outcomes in patients with refractory seizures. METHODS: Patients who underwent PET-CT and MRI fusion, scalp and intracranial EEG, and subsequent surgical intervention were retrospectively included. PET-CT were fused with MRI and interpreted by an experienced blinded reader. An area of hypometabolism on PET was identified as the location of the epileptic focus. The site of seizure focus was correlated with scalp and intracranial EEG findings. Surgical outcomes were evaluated. Thirty-six patients were included; all had presurgical PET-CT, scalp EEG, and PET-MRI fusion, and 28 of these patients had intracranial EEGs. RESULTS: PET-CT showed concordance of epileptic foci with scalp EEG in 7/36 patients (19%) and with intracranial EEG in 9/28 patients (32%). PET-MRI was concordant with scalp EEG in 6/36 patients (17%) and with intracranial EEG in 8/28 patients (29%). All patients with concordance of epileptic foci between PET-CT and PET-MRI and scalp EEG had improvement or resolution of seizures postintervention, and 89% of patients had concordance between intracranial EEG and PET studies. However, 45% of patients with discordant PET-CT and scalp EEG, 37% with discordance PET-CT and intracranial EEG, 43% with discordant PET-MRI and scalp EEG, and 35% of patients with discordant PET-MRI and intracranial EEG did not improve postsurgically. CONCLUSION: Concordance of epileptic foci localization between PET imaging and EEG yields favorable postoperative outcome in nearly all patients, whereas discordance has an equal probability of favorable vs unfavorable outcomes.

Improving Hepatobiliary Imaging as a Physiologic Test with Superior Clinical Outcomes.

This study aims at prospectively evaluating the difference in the effect of cholecystokinin (CCK) and half-and-half milk (HHM) administered in the same patient on gallbladder contractility and correlation with clinical outcomes. Upon gallbladder visualization during standard hepatobiliary imaging, 0.02 µg/kg of CCK was injected over 3 min, and additional 30 min of dynamic imaging was obtained. Patients with gallbladder ejection fraction (GBEF) <35% after CCK were administered 8 oz of HHM followed by 30 min of imaging. The GBEF was recalculated. The number of patients whom GBEF changed from below 35% (abnormal) after CCK to above 35% (normal) after HHM was recorded. Follow-up of the clinical outcome at 6 months was performed. Fifty patients with abnormal GBEF were prospectively included. The average GBEF after CCK was 14.7% ± 8.5% and after HHM was 30.7% ± 20.8%. The average increase in GBEF with HHM was 16.0% ± 22.2%. The GBEF changed from abnormal to normal in 17 patients (34%). The remaining 33 patients remained abnormal. Clinical outcomes at 6 months were available in 47 patients. Cholecystectomy was performed in 60% of patients with abnormal GBEF with CCK and HHM with resolution or improvement of pain. Two of 16 patients (12%) with abnormal GBEF after CCK but normal after HHM had cholecystectomies with pain improvement, while 8 out of these patients (50%) were diagnosed and treated with other disorders and improved. Hepatobiliary imaging with HHM stimulation is a superior physiologic test which can lower the number of unnecessary cholecystectomies and misdiagnoses as functional cholecystitis.

State of family medicine practice in Lebanon.

BACKGROUND: Many difficulties are encountered in family medicine practice and were subject to multinational studies. To date, no study was conducted in Lebanon to assess the challenges that family physicians face. This study aims to evaluate the family medicine practice in Lebanon stressing on the difficulties encountered by Lebanese family physicians. MATERIALS AND METHODS: A questionnaire was sent to all 96 family medicine physicians practicing in Lebanon. Participants answered questions about characteristics of family medicine practice, evaluation of the quality of work, identification of obstacles, and their effect on the medical practice. RESULTS: The response rate was 59%, and the average number of years of practice was 10.7 years. Physicians complain mainly of heavy load at work, too many bureaucratic tasks, demanding patients, and being undervalued by the specialists. Most physicians are able to adapt between their professional and private life. CONCLUSION: Despite all the obstacles encountered, Lebanese family physicians have a moderate satisfaction toward their practice. They remain positive and enthusiastic about their profession. Until the ministry of public health revises its current health system, the primary care profession in Lebanon will remain fragile as a profession.

Prevalence and correlates of alcohol abuse and dependence in Lebanon: results from the Lebanese Epidemiologic Survey on Alcohol (LESA).

The current article aimed to determine the 12-month prevalence and correlates of DSM-IV alcohol abuse and dependence in a nationally representative sample of Lebanese adults. One thousand participants collaborated in face-to-face interviews in 2011. Prevalence of 12-month alcohol dependence was 5%, with a higher risk for those who were men, unmarried, the youngest adults (aged between 18 and 34 years old), students, participants with a liberal occupation, participants with a low income, participants with a positive family history of alcohol misuse, and smokers. Prevalence of 12-month alcohol abuse was 6.2%, with a higher risk for those who were men, students, employees, and Druze and Christians compared to Muslims. Current alcohol abuse and dependence were found to be very highly prevalent in Lebanon.

Assessment of clinical reasoning in the context of uncertainty: the effect of variability within the reference panel.

The Script Concordance Test (SCT) assesses reasoning in the context of uncertainty. Because there is no single correct answer, scoring is based on the comparison of answers provided by examinees with those provided by members of a reference panel made up of experienced practitioners. The study aimed to assess the discriminatory power of the SCT based on the variability of the reference panel's answers. Items from a bank covering different family medicine domains were classified into 3 groups according to the degree of variability of answers provided by a pool of experienced doctors. A variability index (mean squared error) was used to select items in the low, moderate and high variability categories. A 102-item test (Cronbach's alpha 0.70), made up of 3 subtests of each category, was administered to 3 contrasting groups in family medicine: 157 clerkship students, 30 residents and 30 practising doctors. anova and effect size (ES) were used to quantify and test the discrimination power of the 3 subtests. The high variability subtest showed high effect size for discrimination between extreme groups (ES = 1.5; F = 16.3, P < 0.001), whereas the moderate variability subtest showed less effect size (ES = 0.56; F = 57, P = 0.041). The low variability subtest did not discriminate significantly (ES = 0.31; F = 2.9, P = 0.06). Variability of answers within the reference panel is a key component of the discriminatory power of the SCT. In accordance with theory, the presence of variability ensures discrimination between levels of clinical experience. These results imply important considerations for the construction of efficient SCTs.
