Suprapatellar Tibial Intramedullary Rod Surgery
Suprapatellar Tibial Intramedullary Rod Surgery samer kareem 10,090 Views • 2 years ago

Intramedullary nailing of the tibia with suprapatellar entry and semi-extended positioning makes it technically easier to nail the proximal and distal fractures. The purpose of this article was to describe a simple method for suprapatellar nailing (SPN). A step-by-step run through of the surgical technique is described, including positioning of the patient. There are as yet only a few clinical studies that illustrate the complications with this method, and there has been no increased frequency of intraarticular damage. Within the body of the manuscript, information is included about intraarticular damage and comments with references about anterior knee pain.

Root Canal  treatment
Root Canal treatment samer kareem 31,785 Views • 2 years ago

“Endo” is the Greek word for “inside” and “odont” is Greek for “tooth.” Endodontic treatment treats the inside of the tooth. Root canal treatment is one type of endodontic treatment. To understand endodontic treatment, it helps to know something about the anatomy of the tooth. 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 creates the surrounding hard tissues of the tooth during development.

Treating Scoliosis with Magnets
Treating Scoliosis with Magnets samer kareem 17,985 Views • 2 years ago

Pediatric orthopedic surgeons at Columbia are using a new device with magnetic technology that avoids the need for multiple spine-lengthening surgeries to correct early-onset scoliosis, a severe curvature of the spine in young children. In April 2014, Michael Vitale, MD, the Ana Lucia Professor of Pediatric Orthopedic Surgery at CUMC and 1995 graduate of P&S, performed the first procedure in the New York area, using the device to treat a 5-year-old boy. When braces and casts cannot control scoliosis in young children, surgeons turn to growing rods, which help correct the curve while allowing the spine to grow. When spinal maturity is near, the rods are removed and a spinal fusion can be performed. But during years of treatment with growing rods, patients must undergo surgery every six months to lengthen the rods to keep up with the patients’ growth. A patient may undergo eight to 10 procedures, which are costly and result in lost time for parents at work and children at school. The new device—MAGEC (MAGnetic Expansion Control) rods—contains a mechanism inside the growing rods that allows surgeons to lengthen the rods with a handheld external magnet, without surgery.

What Is Cervicitis ?
What Is Cervicitis ? samer kareem 4,650 Views • 2 years ago

Cervicitis is an inflammation of the cervix, the lower, narrow end of the uterus that opens into the vagina. Possible symptoms of cervicitis include bleeding between menstrual periods, pain with intercourse or during a cervical exam, and abnormal vaginal discharge. However, it's also possible to have cervicitis and not experience any signs or symptoms. Often, cervicitis results from a sexually transmitted infection, such as chlamydia or gonorrhea. Cervicitis can develop from noninfectious causes, too. Successful treatment of cervicitis involves treating the underlying cause of the inflammation.

Lipid Lowering Agents

Lipid-Lowering Agents HMG-CoA reductase inhibitors (statins) These agents inhibit the rate-limiting step in cholesterol biosynthesis by competitively inhibiting HMG-CoA reductase. Note the following: Low-density lipoprotein (LDL) reduction of 25%-60% Examples include Atorvastatin, fluvastatin, lovastatin, pitavastatin, pravastatin, rosuvastatin, simvastatin Contraindications include hypersensitivity, active liver disease, pregnancy, lactation, coadministration with strong CYP3A4 inhibitors (selected statins) Vitamin B3 Vitamin B3 inhibits very-low-density lipoprotein (VLDL) synthesis. Note the following: LDL reduction of 10% High-density lipoprotein (HDL) increase of 20% Example includes Niacin (nicotinic acid) Contraindications include hypersensitivity, liver disease, active peptic ulcer, severe hypotension, arterial bleeding Fibrates Fibrates enhance lipoprotein lipase, resulting in increased VLDL catabolism, fatty acid oxidation, and triglycerides elimination. They decrease hepatic extraction of free fatty acids. Note the following: LDL reduction of 15% Triglyceride reduction of 35% Examples include Gemfibrozil, fenofibrate, fenofibrate (micronized), fenofibric acid Contraindications include active liver disease, renal disease, primary biliary cirrhosis, gallbladder disease 2-Azetidiones These agents inhibit sterol transporter at brush border and, consequently, intestinal absorption of cholesterol. LDL reduction of 15% Example includes Ezetimibe Contraindications include hypersensitivity, coadministration with statins (if active liver disease) Bile acid sequestrants These agents lower cholesterol and LDL via bile duct sequestration. Note the following: LDL reduction of 15% Examples include Cholestyramine, colesevelam, colestipol Contraindications include biliary/bowel obstruction, serum triglycerides >300-500 mg/dL, history of hypertriglyceridemia-induced pancreatitis
