Respiratory allergies are the most important public health issues in the world. They are caused by aeroallergens which play great role in pathogenesis of respiratory allergic diseases. The current study was conducted to evaluate the prevalence of positive skin test for various aeroallergens among allergic patients in Ahvaz, southwest Iran. 299 participants with allergic rhinitis (seasonal or perennial) were selected. Skin prick test using twenty three common allergen extracts was performed on all patients. The overall frequency of sensitization to any allergen was 85.6%. In outdoor allergens the most prevalent aeroallergen category was weeds (89%) followed by tree and grasses, and in indoor allergens, mites (43%) were the most prevalent aeroallergen. The mean and median numbers of positive test reactions among those with positive test responses were 11.5 and 13.0, respectively. 84% of patients were poly-sensitised and about 50% of them were sensitised to more than twelve different allergens. The results of the study revealed that prevalence of the skin prick reactivity to weed pollens is significant in southwest Iran and multiple sensitizations were common.

BACKGROUND፡ Fostering critical thinking (CT) is one of the most important missions in medical education. Concept mapping is a method used to plan and create medical care through a diagrammatic representation of patient problems and medical interventions. Concept mapping as a general method can be used to improve CT skills in medical students. The aim of this study was to explore the effect of concept mapping on CT skills of medical students.METHODS: This quasi-experimental study was conducted on 100 second-year medical students which take an anatomy course. Participants were randomly assigned into a control group (lecture-based) and an intervention group (concept mapping). CT levels of medical students were assessed using the California Critical Thinking Skills Test. Data were analyzed using independent sample t-test.RESULTS: Before intervention, CT scores of the intervention and control groups were 6.68 ± 2.55 and 6.64±2.74, respectively, and after intervention, they were 11.64±2.29 and 10.04 ± 3.11, respectively. Comparison of mean score differences for both groups before and after intervention demonstrated that CT scores in the experimental group significantly increased after intervention (P=0.021).CONCLUSIONS: Medical students who were taught through concept mapping showed an increase in CT scores, compared with those in the control group. Medical students require effective CT skills in order to make sound knowledge-based assessment and treatment choices during patient care. Therefore, instructors and planners of medical education are expected to apply this educational strategy for developing CT skills in medical students.

Background: The duration of protection following primary series vaccination against hepatitis B is unknown in children and adolescents. It has been shown that the level of anti-hepatitis B surface antigen antibodies (anti HBs Ab) declines over years after vaccination. Objectives: The aim of this study was to estimate the long-term immunity against hepatitis B virus infection among children and adolescents who had received a complete hepatitis B vaccination series during infancy. Patients and Methods: In a cross-sectional study, the - anti-HBsAb levels of 840 vaccinated children and adolescents were determined by enzyme-linked immunosorbent assay. Results: Hepatitis B seroprotection rates (anti HBsAb ≥ 10 IU/L) among vaccinated children and adolescents aged 1 and 18 years were 90% and 48.9%, respectively. The declining trend of geometric mean titer of anti-HBsAb levels was observed as changed from 272.3 IU/L to 94.1 IU/L in 1 and 18-year-old population, respectively. A significant negative correlation was found between age and anti-HBsAb levels (r = - 0.220, P = 0.0001). Conclusions: The results showed a declining trend in anti-HBsAb titers over the time after vaccination against hepatitis B virus in our region. Further studies are warranted to establish the need for a booster dose in cases that are at risk of hepatitis B virus infection. Keywords: Hepatitis B ; Vaccination ; Iran

The prevalence of asthma was determined in a random sample of schoolchildren in Ahvaz city, southwest Islamic Republic of Iran, based on the International Study of Asthma and Allergy in Childhood (ISAAC) protocol. The prevalence of ever wheeze and current wheeze was 11.1% and 7.4% among 1410 children aged 6-7 years (parent-reported) and 17.7% and 10.3% among 1450 children aged 13-14 years (self-reported). The prevalence of ever asthma was significantly higher among 13-14-year-olds (9.8%) than 6-7-year-olds (6.8%) but no significant difference was found between males and females in either age group. Comparisons are made with other Iranian cities and international data.

Background: Burnout is a work-related syndrome that can affect physicians’ performance. Empathy is one of the clinical competencies in whose formation many factors play a role. Empathy and burnout are important topics of research in medical sciences, and both are related to the communication between the patient and the physician. This study investigated the relationship between occupational burnout and empathy among medical residents. Method: This cross-sectional study was conducted on 297 medical residents in Ahvaz Jundishapur University of Medical Sciences from January to March 2021. The data collection tools were the Jefferson Scale of Empathy (JSE) and the Maslach Burnout Inventory (MBI). The reliability of the instruments was measured by calculating Cronbach’s alpha. Data were analyzed by SPSS-18, using the Pearson correlation test and linear regression models. Results: The average age of the study population was 33.06 ±4.7 years, with more than half being females (57.6%) and married (51.9%). The residents’ mean scores of empathy and overall burnout were 102.87 out of 140 and 55.90 out of 132, respectively. The burnout scores showed an inverse correlation with the overall empathy scores (r = −0.123, P = 0.035), and the score of standing in the patient’s shoes (r = −0.165, P = 0.004). Linear regression test was used to detect which dimension of empathy was a better predictor for the reduction of burnout scores. Results showed that the best predictor was standing in the patient’s shoes (P = 0.014). Conclusion: The findings showed a negative association between empathy and burnout among medical residents, which suggests the need for adjustment of the existing burnout management at the institutional level. Therefore, residents should be supported by managers to reduce burnout and improve their empathic behavior.

Investigations into the epidemiology of acute flaccid paralysis (AFP) are an essential strategic component of the Global Poliomyelitis Eradication Initiative of the World Health Organization (WHO), and are part of the certification process for polio eradication worldwide. This is an epidemiological report of AFP incidence in children less than 15 years old in southwest Iran. This was a retrospective cohort study, carried out based on WHO guidelines, in which we reviewed non-polio AFP cases recorded from January 2006 to December 2010 in different regions of Khuzestan Province, southwest Iran. In this study, the records of all children under 15 years old with AFP were evaluated. During a 5-year period, 137 cases of AFP were reported (incidence rate, 2.21 per 100,000 children <15 years old). More than 50% (73 of 137) of the cases were boys, and 52.6% (72 of 137) were under 5 years of age, with a mean age of 5.39±3.98 years. The incidence of AFP was significantly higher in older children (p=0.001). The most common cause of paralysis was Guillain-Barré syndrome (117 of 137). None of the cases were diagnosed with acute poliomyelitis. In this study, we found that the incidence rate of AFP in the region was almost in agreement with the expected incidence of AFP in children less than 15 years old; therefore, the AFP surveillance program in Khuzestan Province is satisfactory in terms of reliability and effectiveness. Nevertheless, routine vaccination against polio and ensuring that patients with AFP receive follow-up are essential for eradicating polio.
