A burden of proof study on alcohol consumption and ischemic heart disease

Cohort and case-control data have suggested an association between low to moderate alcohol consumption and decreased risk of ischemic heart disease (IHD), yet results from Mendelian randomization (MR) studies designed to reduce bias have shown either no or a harmful association. Here we conducted an updated systematic review and re-evaluated existing cohort, case-control, and MR data using the burden of proof meta-analytical framework. Cohort and case-control data show low to moderate alcohol consumption is associated with decreased IHD risk – specifically, intake is inversely related to IHD and myocardial infarction morbidity in both sexes and IHD mortality in males – while pooled MR data show no association, confirming that self-reported versus genetically predicted alcohol use data yield conflicting findings about the alcohol-IHD relationship. Our results highlight the need to advance MR methodologies and emulate randomized trials using large observational databases to obtain more definitive answers to this critical public health question

Unique case of esophageal rupture after a fall from height

<p>Abstract</p> <p>Background</p> <p>Traumatic ruptures of the esophagus are relatively rare. This condition is associated with high morbidity and mortality. Most traumatic ruptures occur after motor vehicle accidents.</p> <p>Case Presentation</p> <p>We describe a unique case of a 23 year old woman that presented at our trauma resuscitation room after a fall from 8 meters. During physical examination there were no clinical signs of life-threatening injuries. She did however have a massive amount of subcutaneous emphysema of the chest and neck and pneumomediastinum. Flexible laryngoscopy revealed a lesion in the upper esophagus just below the level of the upper esophageal sphincter. Despite preventive administration of intravenous antibiotics and nutrition via a nasogastric tube, the patient developed a cervical abscess, which drained spontaneously. Normal diet was gradually resumed after 2.5 weeks and the patient was discharged in a reasonable condition 3 weeks after the accident.</p> <p>Conclusions</p> <p>This case report presents a high cervical esophageal rupture without associated local injuries after a fall from height.</p

Controversies in the Surgical Management of Sigmoid Diverticulitis

The timing and appropriateness of surgical treatment of sigmoid diverticular disease remain a topic of controversy. We have reviewed the current literature on this topic, focusing on issues related to the indications and types of surgery. Current evidence would suggest that elective surgery for diverticulitis can be avoided in patients with uncomplicated disease, regardless of the number of recurrent episodes. Furthermore, the need for elective surgey should not be influenced by the age of the patient. Operation should be undertaken in patients with severe attacks, as determined by their clinical and radiological evaluation

Sentinel Contributions of US Department of Veterans Affairs Surgeons in Shaping the Face of Health Care

The vast accomplishments of the US Department of Veterans Affairs (VA) during the past century have contributed to the advancement of medicine and benefited patients worldwide. This article highlights some of those accomplishments and the advantages in the VA system that promulgated those successes. Through its affiliation with medical schools, its formation of a structured research and development program, its Cooperative Studies Program, and its National Surgical Quality Improvement Program, the VA has led the world in the progress of health care. The exigencies of war led not only to the organization of VA health care but also to groundbreaking, landmark developments in colon surgery; surgical treatments for vascular disease, including vascular grafts, carotid surgery, and arteriovenous dialysis fistulas; cardiac surgery, including implantable cardiac pacemaker and coronary artery bypass surgery; and the surgical management of many conditions, such as hernias. The birth of successful liver transplantation was also seen within the VA, and countless other achievements have benefited patients around the globe. These successes have created an environment where residents and medical students are able to obtain superb education and postgraduate training and where faculty are able to develop their clinical and academic careers
