BACKGROUND: Emergencies such as road traffic accidents (RTAs), acute myocardial infarction (AMI) and cerebrovascular accident (CVA) are the most common causes of death and disability in India. Robust emergency medicine (EM) services and proper education on acute care are necessary. In order to inform curriculum design for training programs, and to improve the quality of EM care in India, a better understanding of patient epidemiology and case burden presenting to the emergency department (ED) is needed.METHODS: This study is a retrospective chart review of cases presenting to the ED at Kerala Institute of Medical Sciences (KIMS), a private hospital in Trivandrum, Kerala, India, from November 1, 2011 to April 21, 2012 and from July 1, 2013 to December 21, 2013. De-identified charts were systematically sampled and reviewed.RESULTS: A total of 1196 ED patient charts were analyzed. Of these patients, 55.35％ (n=662) were male and 44.7％ (n=534) were female. The majority (67.14％,n=803) were adults, while only 3.85％ (n=46) were infants. The most common chief complaints were fever (21.5％, n=257), renal colic (7.3％,n=87), and dyspnea (6.9％,n=82). The most common ED diagnoses were gastrointestinal (15.5％,n=185), pulmonary (12.3％,n=147), tropical (11.1％,n=133), infectious disease and sepsis (9.9％,n=118), and trauma (8.4％,n=101).CONCLUSION: The patient demographics, diagnoses, and distribution of resources identifi ed by this study can help guide and shape Indian EM training programs and faculty development to more accurately refl ect the burden of acute disease in India.

To assess the effect of a NO-eluting stent on reducing neointimal thickening in a porcine coronary artery stent injury model, sodium nitroprusside (SNP), a NO donor, was incorporated into polyurethane (PU) polymer and coated onto metallic coil stents, and two types of stents with thin and thick barrier coatings were characterized. In vivo biological activity of the NO-eluting stents was assessed by measurement of coronary arterial cGMP levels in 32 pigs/64 arteries at days 1, 2, 7 and 14. Morphometric analyses were performed in 16 pigs to determine the effect of NO-eluting stents on neointimal hyperplasia 28 days following arterial injury. The SNP-coated stents released NO in a controlled manner for up to 4 weeks in the in vitro experiments and an increase in local tissue cGMP levels was demonstrated for up to 14 days. The neointimal area at 28 days was not diminished, however, by NO eluded from either stents of thin or thick barriers (control bare stent - 0.66 mm2, control PU stent - 0.68 mm2, SNP-PU thin coating stent - 0.78 mm2, SNP-PU thick coating stent - 0.85 mm2; all p=NS). In conclusion, the SNP-coated polymer stent exerted a local biological effect on the arterial wall, with sustained elevation of cGMP level. Although local delivery of NO from this device did not reduce neointimal hyperplasia in this porcine model, this polymer-coated stent might be a promising tool for administration of other agents that may modify the reparative tissue responses leading to restenosis.
