Portal hypertension is an increase in the blood pressure within a system of veins called the portal venous system. Veins coming from the stomach, intestine, spleen, and pancreas merge into the portal vein, which then branches into smaller vessels and travels through the liver.
One of the criteria to determine brain death is the irreversible absence of cerebral and brainstem reflexes including pupillary, oculocephalic, oculovestibular (caloric), corneal, gag, sucking, swallowing, and extensor posturing. Some of the other criteria for determination of brain death include: 1. Absence of respiratory drive (apnea) off the ventilator for a duration that is sufficient to produce hypercarbic drive (usually 10 to 20 minutes to achieve pC02 of 50 to 60 mmHg) ( 2. Body temperature below 34 C (93.2 F) 3. EEG isoelectric for 30 minutes at maximal gain 4. Absence of cerebral circulation by Doppler or magnetic resonance angiography 5. At least 24 hours of observation in adults with anoxic-ischemic brain damage with a negative drug screen

Despite the effective diagnostic and treatment options available today, Dr. Wolfe notes that he continues to see a high number of untreated scaphoid fractures that have progressed to nonunion. However, he adds that this may not be the result of a missed diagnosis, but rather more related to the relatively innocuous injury that causes a low level of suspicion. Recognition and awareness of scaphoid fractures is higher today among primary care providers, emergency room physicians, pediatricians, and sports trainers, but fully 15% of patients with suggestive physical findings and normal initial x-rays will have an “occult”, or concealed, scaphoid fracture. Specialized imaging studies are critical at an early stage to reduce the chance of scaphoid nonunion.
Dopamine is the one neurotransmitter that everyone seems to know about. Vaughn Bell once called it the Kim Kardashian of molecules, but I don’t think that’s fair to dopamine. Suffice it to say, dopamine’s big. And every week or so, you’ll see a new article come out all about dopamine.
Every owner of a building where asbestos abatement activity occurs is responsible for the performance of the asbestos abatement activities by his/her agent, contractor, employee, or other representative. Each building owner is responsible for determining the amount of asbestos-containing material that may be disturbed during the course of work. The size and scope of the overall project, with particular reference to the total amount of asbestos-containing material that will be disturbed determines the reporting or filing requirements established in the Asbestos Control Program Rules. An asbestos project is defined as any form of work that will disturb more than 25 linear feet or more than 10 square feet of asbestos-containing material.
Meckel's Diverticulum is a vestigeal remnant of vitellointestinal duct. Its a true diverticulum as it contains all three layers of intestine. It is usually presents at anti mesenteric burder. Usually 2 cm (range 1- 12 cm ) in length, found in 2 % of population , and situated around 2 feet of Ileaocecal junction. 50 % cases it contains gastric mucosa , but may also contain colonic, duodenal or pancreatic mucosa .male : female ration in symptomatic cases is 3 : 1.It may mimic acute appendicitis, so in cases where one is going for surgery for appendicitis , must search for meckel's diverticulum........
