We herein report a witnessed cardiopulmonary collapse of a patient with difficult mask ventilation and near-impossible laryngoscopy-cum-intubation in the critical care unit. The airway was successfully rescued with a laryngeal mask airway Supreme™, followed by an open, crash tracheostomy by the otolaryngologist.

BACKGROUND: Motor vehicle crash (MVC) related injury has been identified as a major public health concern. Child restrain (CR) seat belts can minimize the mortality and morbidity from MVC. The use for seat belts is substantially low in developing countries like Pakistan even though its use has been shown to decrease morbidity and mortality by a significant extent. METHODS: This was a case control study with cases from the general population (GP) and controls from the Aga Khan University (AKU) employees in a 3:1 ratio. The study questionnaire was based on parameters like gender, education level, awareness and presence of CR and also assessed the frequency of usage, reasons for not using CR and the source of knowledge regarding CR use. RESULTS: Out of 848 respondents, 212 were from AKU and 636 were from the GP. 96.7% from AKU had at least a bachelor's degree while less than half (42.6%) of those from the GP were graduate or above (P<0.001). A statistically significant difference was found between the two groups with drivers from AKU being generally more aware about CR and its use. 81.1% of the group from AKU compared to 59.7% from the general population were found to be aware of child restraint use (P<0.001). Media (40.6%) was found to be the most common source of information amongst the AKU employees. CONCLUSION: Most motor vehicle related injuries in children can be prevented or their severity may be reduced by the use of appropriate child restraint seat belts.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that affects the overall cognitive, emotional, social, and physical health of the affected individual. It is characterised by challenges in social communication and interaction, repetitive and stereotyped behaviours, and narrow interests. The pathogenesis of ASD is thought to involve a combination of genetic and environmental factors. Increasing evidence suggests that vitamin D deficiency during pregnancy and early childhood may contribute to the development of ASD. While studies have indicated that vitamin D supplementation can significantly improve symptoms of ASD, the underlying mechanism remains elusive. This review summarises the association between vitamin D levels and ASD, explores potential mechanisms underlying vitamin D's role in ASD, and examines the effect of vitamin D supplementation on ASD symptoms.

India has a great wealth of various naturally occurring plant drugs which have great potential pharmacological activities. Datura stramonium (D. stramonium) is one of the widely well known folklore medicinal herbs. The troublesome weed, D. stramonium is a plant with both poisonous and medicinal properties and has been proven to have great pharmacological potential with a great utility and usage in folklore medicine. D. stromonium has been scientifically proven to contain alkaloids, tannins, carbohydrates and proteins. This plant has contributed various pharmacological actions in the scientific field of Indian systems of medicines like analgesic and antiasthmatic activities. The present paper presents an exclusive review work on the ethnomedical, phytochemical, pharmacological activities of this plant.

Autophagy is a self-eating process,in which the damaged or excessed cell organelles and misfolded protein aggregates are removed from the cellular microenvironment.Autophagy is generally thought of as a pro-survival mechanism which is not only important for balancing energy supply at times of nutrient deprivation but also in the removal of various stress stimuli to ensure homeostasis.In addition to the target materials of"self"origin,autophagy can also eliminate intracellular pathogens and acts as a de-fense mechanism to curb infections.In addition,autophagy is linked to the host cell's innate immune response.However,viruses have evolved various strategies to manipulate and overtake host cell ma-chinery to establish productive replication and maintain infectious process.In fact,replication of many viruses has been found to be autophagy-dependent and suppression of autophagy can potentially affect the viral replication.Thus,autophagy can either serve as an anti-viral defense mechanism or a pro-viral process that supports viral replication.Hepatitis B virus(HBV)and hepatitis C virus(HCV)are known to co-opt cellular autophagy process as a pro-viral tool.Both viruses also induce mitophagy,which con-tributes to the establishment of chronic hepatitis.This review focuses on the roles of autophagy and mitophagy in the chronic liver disease pathogenesis associated with HBV and HCV infections.

The growing proportion of individuals suffering from chronic kidney disease has considerable repercussions for both kidney specialists and primary care. Progressive and permanent renal failure is most frequently treated with hemodialysis. The efficiency of hemodialysis treatment relies on the functional status of vascular access. Determining the type of vascular access has prime significance for maximizing successful maturation of a fistula and avoiding surgical revision. Despite the frequency of arteriovenous fistula procedures, there are no consistent criteria applied before creation of arteriovenous fistulae. Increased prevalence and use of arteriovenous fistulae would result if there were reliable criteria to assess which arteriovenous fistulae are more likely to reach maturity without additional procedures. Published studies assessing the predictive markers of fistula maturation vary to a great extent with regard to definitions, design, study size, patient sample, and clinical factors. As a result, surgeons and specialists must decide which possible risk factors are most likely to occur, as well as which parameters to employ when evaluating the success rate of fistula development in patients awaiting the creation of permanent access. The purpose of this literature review is to discuss the role of patient factors and blood markers in the development of arteriovenous fistulae.

Phrenic nerve palsy causing hemidiaphragm paralysis is a very uncommon feature of thoracic aortic aneurysm. In one case, a 45-year-old man complained of chronic chest pain, dysphagia, and hoarseness of voice; posteroanterior view chest radiograph revealed lobular enlargement of the superior mediastinum and elevated right hemidiaphragm. Contrast-enhanced computed tomography (CT) of the thorax revealed a giant partially thrombosed aneurysm originating from the ascending aorta and extending into the aortic arch, causing a widening of the aorta-pulmonary window and a compression of the thoracic esophagus. Right hemidiaphragm elevation was explained by the gross mass effect of the aneurysm on the right hilum, causing right phrenic nerve palsy. The patient was to be operated on for surgical correction of the aneurysm, but died before surgery due to spontaneous rupture.

Objective To investigate the restrictive factors in the development of foreign medical education. Methods From the years 2011 to 2013, 350 foreign students conducted a questionnaire survey in Chongqing Medical University, and recovered 339 valid questionnaires. Results Only 33.0%(112/339) students thought that the teacher's English was fluent and 70.2% (238/339) needed to add Chinese class. Additionally, 69.6% (236/339) and 63.1% (214/339) students considered theoretical knowledge and practi-cal experience were not enough. 92.3%(313/339) students came from developing countries in Southeast Asia. 86.1%(292/339) foreign students considered that university management was insufficient. Conclusion The survey found the restrictive factors included students' demand for English and Chinese, lack of medical ex-pertise and practice, the problem of student sources and daily management difficulties and so on.
