Value of subspecialty experience in internal medicine undergraduate training

We aimed from our study to assess how students and clinical supervisors perceive students' achievement in the internal medicine subspecialty clinical attachments in comparison with the general attachments. We conducted a cross-sectional study comparing students' self-assessment ratings during the Medicine Block general and subspecialties clinical attachments at our college of medicine during the period between February 2007 and June 2009. We assessed the level of agreement between students' self-assessment in the different subspecialties with their self-assessment in the general attachments. We repeated the same calculation for the supervisors' assessment. Eighty-three students were included; these students attended eight different clinical attachments. A total of 517 self-assessment forms were completed (120 general internal medicine clinical attachments and 397 forms in different specialty attachments). The clinical supervisors completed parallel assessment forms. The undergraduate medical students' perceived their achievement in the subspecialty attachments well. This was similar to their perception of their achievement in the general clinical attachments. The clinical supervisors perceived students achievement in the subspecialties to be similar to their achievement in the general clinical attachments. In conclusion, we do encourage the implementation of specialty and subspecialty undergraduate clinical attachments for all students as part of their curriculum requirements. Furthermore, we encourage the strategic utilization of specialties/subspecialties attachment distribution aiming to enhance students' future interest to achieve balance in the different health specialties/subspecialties manpower. Further research to support this recommendation is needed.     

Level of histamine in supernatants from the basophil activation test: applications to hymenoptera allergy and drug allergy--preliminary study

Histamine Release technic consists in calculating histamine liberated by blood cells in touch with an allergen. To this day, this method is only used in Hymenoptera venom allergy diagnosis. The principle of this study is to measure histamine released by activated basophils in surnageons of Basophil Activation Test (BAT) for different allergens: Hymenoptera venoms: Bee, White Faced Hornet, Vespula Wasp. Drugs: Cefaperos, Clamoxyl, Alfatil, Rapifen, Diprivan, Nesdonal, Mivacron. A threshold of positivity (amplification factor in comparison with the control) is determined for these two classes of allergens: 45 for Hymenoptera venoms and 9 for drugs. These results, compared to the other diagnosis technics (Histamine Release, Basophil Activation Test, Prick Tests) discloses very high correlation rates in each case. This method seems to be a reliable method for Hymenoptera venom allergy diagnosis and for drugs allergy diagnosis too. However, this study is based on a few number of patients, so a significant statistic conclusion can't be expressed but it opens an interesting way of research.     

Endocarditis‐induced thrombotic thrombocytopenic purpura mimicking preeclampsia: A case report

TTP, Preeclampsia have similar manifestations in pregnancy. Establishing the right diagnosis is essential as the treatment is different. Endocarditis‐induced TTP should be suspected when neurological symptoms, thrombocytopenia are present.     

Outcomes of septic cirrhosis patients admitted to the intensive care unit: A retrospective cohort study

The aim of this study is to examine the outcome of septic patients with cirrhosis admitted to the intensive care unit (ICU) and predictors of mortality.Single center, retrospective cohort study.The study was conducted in Intensive care Department of King Abdulaziz Medical City, Riyadh, Saudi Arabia.Data was extracted from a prospectively collected ICU database managed by a full time data collector. All patients with an admission diagnosis of sepsis according to the sepsis-3 definition were included from 2002 to 2017. Patients were categorized into 2 groups based on the presence or absence of cirrhosis.The primary outcome of the study was in-hospital mortality. Secondary outcomes included ICU mortality, ICU and hospital lengths of stay and mechanical ventilation duration.A total of 7906 patients were admitted to the ICU with sepsis during the study period, of whom 497 (6.29%) patients had cirrhosis. 64.78% of cirrhotic patients died during their hospital stay compared to 31.54% of non-cirrhotic. On multivariate analysis, cirrhosis patients were at greater odds of dying within their hospital stay as compared to non-cirrhosis patients (Odds ratio {OR} 2.53; 95% confidence interval {CI} 2.04 – 3.15) independent of co-morbidities, organ dysfunction or hemodynamic status. Among cirrhosis patients, elevated international normalization ratio (INR) (OR 1.69; 95% CI 1.29-2.23), hemodialysis (OR 3.09; 95% CI 1.76-5.42) and mechanical ventilation (OR 2.61; 95% CI 1.60–4.28) were the independent predictors of mortality.Septic cirrhosis patients admitted to the intensive care unit have greater odds of dying during their hospital stay. Among septic cirrhosis patients, elevated INR and the need for hemodialysis and mechanical ventilation were associated with increased mortality.     

Exposure of Children to Environmental Tobacco Smoke (ETS) and Its Association with Respiratory Ailments

Objectives. To assess the impact of domestic passive smoking (cigarettes or narghile) on the development of respiratory ailments among children ages 10-15 years. Methods. Students were recruited from five private schools in Beirut, and information on demographic, in-home smoking, and students' respiratory tract illnesses (cough, wheezing, runny nose, or nasal congestion) were collected from each participant. Results. Of 625 students surveyed, 438 (70.1%) had at least one individual smoking at home. Compared with the nonexposed group, the odds ratio of having respiratory illness for children exposed to narghile or cigarette smoke were 2.3 (95% Confidence Iinterval [CI] 1.1-5.1) and 3.2 (95% CI 1.9-5.4), respectively. Conclusions. In addition to the well-established effect of smoking, domestic passive smoking of the misconceived “innocuous” habitual smoking device, narghile, is associated with significant respiratory health ailments.     

Effects of giardiasis on school success, weight and height indices of primary school children in Turkey

BACKGROUND: Giardia intestinalis, the most common parasite in the world, causes several adverse effects on school children, with the prevalence rate ranging between 7.3% and 28% (mean 13.8%) in Turkey. The aim of the present study was to investigate possible adverse effects of G. intestinalis on success at school, and the mean weight and height of primary school children in Sivas, Turkey. METHODS: Five primary schools from central Sivas, Turkey, had a number of students from different socioeconomic conditions and regions. The stool specimens were examined by light microscopy for giardiasis using saline-Lugol and/or zinc sulfate flotation method. Three groups in the present study include the symptomatic giardiasis group (SG), which included children with giardiasis along with abdominal pain and/or diarrhea, the asymptomatic giardiasis group (ASG) without any symptom and the non-parasitic (NPG) group without any parasites. RESULTS: While 599 (34.6%) out of 1730 children were parasitic, 192 (11.1%) had only G. intestinalis. Ninety-eight (5.7%) of 192 were SG (with diarrhea and/or abdominal pain and 94 (5.4%) were ASG. The weights and heights were lower in the children with giardiasis than the children without any parasite. There was a significant difference between the giardiasis group and NPG when the numbers of persons living in the house were compared. While there were no significant difference between the giardiasis group and NPG when the sexes were compared, success at school and economical levels were found to be significantly different between these groups. CONCLUSION: There was a higher prevalence of giardiasis in primary school children and their physical and mental conditions were affected adversely. Giardia infections in particular have adverse effects on success at school.
