Super Obese individuals (people with a Body Mass Index over 45) have an increased risk during any surgery. And the longer the time under anesthesia, the greater the risk. Gastric bypass surgery can last over 2 hours. Duodenal switch surgery often takes over 4 hours. That’s a long time to be under anesthesia.
Glycogen storage disease (GSD, also glycogenosis and dextrinosis) is the result of defects in the processing of glycogen synthesis or breakdown within muscles, liver, and other cell types. GSD has two classes of cause: genetic and acquired.

In patients with advanced congestive heart failure due to cardiomyopathy or ischemia, right ventricle shortening is the only significant independent associate of survival by multivariate analysis (as opposed to other parameters including left ventricular ejection fraction, cardiac index, and pulmonary resistance).
Nasal polyps are linked to allergic rhinitis, asthma, aspirin allergy, sinus infections, acute and chronic infections, something stuck in the nose, and cystic fibrosis. But many times the cause is unknown. Sometimes, people get them before they develop asthma or sinusitis
The two biggest considerations when choosing a suture are the location and tension of the wound. Other important considerations are tensile strength, knot strength, handling, and tissue reactivity. Sutures are divided into two major groups: Absorbable – lose the majority of their tensile strength in less than 60 days. They are generally used for buried sutures and do not require removal. Non-absorbable – maintain the majority of their tensile strength for more than 60 days. They are generally used for skin surface sutures and do require removal postoperatively. Suture needles also come in a variety of shapes and sizes. Curved needles are almost exclusively used in dermatological surgery. Cutting needles move through the tissue more easily and may have their primary cutting edge on the inside of the curve (conventional cutting) or outside of the curve (reverse cutting). The benefit of reverse cutting is that the tapered puncture left by the suture is directed away from the wound edge and therefore tissue tearing is less common. Non-cutting round needles cause even less tissue tearing and may be especially useful in delicate areas and fascia.
Sickle cell anemia (sickle cell disease) is a disorder of the blood caused by an inherited abnormal hemoglobin (the oxygen-carrying protein within the red blood cells). The abnormal hemoglobin causes distorted (sickled) red blood cells.
Pancreatic Auto Islet Transplantation is a procedure used to maintain insulin production and secretion in patients with chronic pancreatitis that are undergoing a total pancreatectomy, or removal of the entire pancreas. When all other medical therapies fail to control the pain, removal of the pancreas may be an option; however it can leave a person diabetic, which means that the body can no longer control blood sugar levels, and will require intensive testing of blood sugar and injections of insulin. The pancreas is an organ, located in the upper abdominal cavity, behind the stomach, liver and colon. Within the pancreas, specialized clusters of cells known as islets produce insulin, which maintain healthy blood sugar levels. The pancreas also produces enzymes to help digest food. In order to alleviate pain and maintain insulin production, the pancreas is removed from the body, processed and the islets are harvested. Once the pancreas is removed, it is placed in a solution and put into a machine where the pancreas is digested. The islets are then infused into the patient’s liver. Within a short time, the islets are expected to start producing insulin. In 80% of patients, the pain from pancreatitis is relieved by a total pancreatectomy. Over time, some patients may be diabetic and will need to take insulin to maintain healthy blood sugar levels. All patients will take pancreatic enzymes to help digest food after surgery.
Bartter syndrome has traditionally been classified into three main clinical variants, as follows: Neonatal (or antenatal) Bartter syndrome Classic Bartter syndrome Gitelman syndrome Advances in molecular diagnostics have revealed that Bartter syndrome results from mutations in numerous genes that affect the function of ion channels and transporters that normally mediate transepithelial salt reabsorption in the distal nephron segments. Hundreds of mutations have been identified to date. Such advances may result in the development of new therapies (see the image below). [2] (See Pathophysiology and Etiology.)
This video shows Prof Dan Reinstein, MD MA(Cantab) FRCSC DABO FRCOphth FEBO performing a ReLEx SMILE keyhole LASIK procedure using the latest surgical instrument that he helped to develop (Malosa MMSU1297 - Reinstein Lenticule Separator: http://www.malosa.com/en/reinstein-le...). This instrument enables the procedure to be performed with one instrument, through one 2mm incision, using only one sweep per plane, and taking about 30 seconds to separate and withdraw the lenticule, improving day 1 uncorrected vision over other lenticule extraction techniques that require more corneal manipulation.
Atrial flutter (AFL) is a type of abnormal heart rate, or arrhythmia. It occurs when the upper chambers of your heart beat too fast. When the chambers in the top of your heart (atria) beat faster than the bottom ones (ventricles), it complicates your heart rhythm
Ovulation is the release of eggs from the ovaries. In humans, this event occurs when the follicles rupture and release the secondary oocyte ovarian cells. After ovulation, during the luteal phase, the egg will be available to be fertilized by sperm
Uncomplicated acute otitis media (AOM) should be treated empirically with amoxicillin. Recurrent AOM should raise concern for beta-lactamase resistance and warrants treatment with amoxicillin-clavulanic acid. Ototopical medications are unnecessary, even if there is tympanic membrane perforation.
Has your dentist or endodontist told you that you need root canal treatment? If so, you're not alone. Millions of teeth are treated and saved each year with root canal, or endodontic, treatment. Remember, root canal treatment doesn't cause pain, it relieves it. Watch our videos below to learn more! Inside the tooth, under the white enamel and a hard layer called the dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves and connective tissue, and helps to grow the root of your tooth during development. In a fully developed tooth, the tooth can survive without the pulp because the tooth continues to be nourished by the tissues surrounding it.
