Oesophageal foreign body in four month old infant

A 4 month old male infant was brought with only strong suspicion of foreign body ingestion without any symptomatology. X-ray examination revealed foreign body at cricopharyngeus, which was managed successfully emphasizing the fact that a strong suspicion and relevant radiography is the key to early and successful management.     

Alcohol use among physicians in a medical school in Nepal

Objective: The objective of the study was to know about the use of alcohol among physicians and factors that were related to it. Methods: This was a cross sectional study conducted among the physicians in a medical school of eastern Nepal. A semi structured questionnaire was used to collect information. Results: There were 55 subjects in the study. Half of them were between 35-45 years age group and one fourth among them were female. There were more than 88% physicians consuming alcohol for more than 10 years. One third used to preferred whisky as their favorites drink. Use of alcohol among them was due to peer pressure and to become a social human being. Most of them drink alcohol occasionally with an average amount 30-60ml in a sitting and usually in the evening. Most of the time, they use alcohol either in parties or at home. Conclusion: Alcohol use in Nepal is very much prevalent. The use of alcohol is socially accepted in many communities. Uses of alcohol by physicians have direct effect on their health as well as the health of many people because they are role model for many people. They are also in direct contact with the patients. Steps to council the physicians may reduce the consumption of alcohol. Key words: Alcohol, Nepal, Physicians, Dependence, Abuse.     

Valproate attenuates dextroamphetamine-induced subjective changes more than lithium

Dextroamphetamine administration in healthy controls produces a range of subjective and physiological effects, which have been likened to those occurring during mania. However, it is uncertain if these can be attenuated by lithium since conflicting results have been reported. To date there have been no previous studies examining the effects of valproate on dextroamphetamine-induced mood and physiological changes. The current study was a double-blind, placebo-controlled, study in which volunteers received either 1000 mg sodium valproate (n = 12), 900 mg lithium (n = 9), or placebo (n = 12) pre-treatment for 14 days. Subjective and physiological measures were then obtained prior to administration of a 25 mg dose of dextroamphetamine, and at two time points after administration. Differences in the response to dextroamphetamine were assessed between the three treatment groups. The results of this study show that pre-treatment with lithium only significantly attenuated dextroamphetamine-induced change in happiness, while valproate pre-treatment significantly attenuated the effects of dextroamphetamine on happiness, energy, alertness and on the diastolic blood pressure. These results suggest that lithium and valproate do not have the same mechanism of action on dextroamphetamine-induced changes, and this finding may relate to differences in their mechanism of action in mood disorders.     

Associations of Emergency Department Visits for Asthma with Precipitation and Temperature on Thunderstorm Days: A Time-Series Analysis of Data from Louisiana,USA, 2010–2012

Background: Studies of thunderstorm asthma to understand risk factors using high-resolution climate data and asthma outcomes on a large scale are scarce. Moreover, thunderstorm asthma is not well studied in the United States.Objectives: We examined whether climate parameters involved in thunderstorms are associated with emergency department (ED) visits for acute asthma attacks in the United States.Methods: We analyzed 63,789 asthma-related, daily ED visits for all age groups, and thunderstorm-associated climate data in Louisiana during 2010 through 2012. We performed time-series analyses using quasi-Poisson regression models with natural cubic splines of date, parish, holiday, day of week, season, daily maximum concentrations of ozone (O3) and fine particulate matter [PM ≤2.5μm in aerodynamic diameter (PM2.5)], and daily mean pressure, precipitation, and temperature. Because of a significant interaction effect between temperature and lightning days on asthma-related visits, we performed stratified analyses by days with/without lightning or thunderstorm (defined by any lightning and precipitation).Results: On thunderstorm days, higher asthma-related ED visits were associated with higher daily mean precipitation [relative risk (RR)=1.145 per 1g/m2/s (95% CI: 1.009, 1.300)] and lower daily mean temperature [RR=1.011 per 1°C change (1.000–1.021)] without carry-over effect to the next non-thunderstorm day. These higher risks were found mainly among children and adults <65 years of age. We observed similar results on lightning days. However, we did not find similar associations for non-thunderstorm or non-lightning days. Daily maximum O3 and PM2.5 levels were not significantly associated with asthma ED visits on thunderstorm days.Discussion: Higher precipitation and lower temperature on thunderstorm days appear to contribute to asthma attacks among people with asthma, suggesting they should consider taking precautions during thunderstorms. EDs should consider preparing for a potential increase of asthma-related visits and ensuring sufficient stock of emergency medication and supplies for forecasted severe thunderstorm days. https://doi.org/10.1289/{"type":"entrez-protein","attrs":{"text":"EHP10440","term_id":"372009825","term_text":"EHP10440"}}EHP10440
