Acute kidney injury is common entity in medical practice. The present definition is based on a serum creatinine rise of more 0.3 mg/dl in 48 hours or less, a 50% increase from the baseline over a period of 07 days or a urine output of less than 0.5 ml/kg/hour for more than 06 hours. The main causes of acute kidney injury may be classified into pre renal, intrinsic or post renal causes. Rapid diagnosis and prompt treatment is essential to prevent mortality or morbidity. This presentation discusses in detail the causes of all three mechanisms, pre-renal, post renal and intrinsic.
The bone marrow aspiration is usually done first. The doctor makes a small incision, then inserts a hollow needle through the bone and into the bone marrow. Using a syringe attached to the needle, the doctor withdraws a sample of the liquid portion of the bone marrow. You may feel a brief sharp pain or stinging.
The hepatic portal system is the system of veins comprising the hepatic portal vein and its tributaries. It is responsible for directing blood from the region of the gastrointestinal tract between the esophagus and rectum and also includes venous drainage from the supplementary organs such as the spleen and pancreas.
Primary sclerosing (skluh-ROHS-ing) cholangitis (koh-lan-JIE-tis) is a disease of the bile ducts, which carry the digestive liquid bile from your liver to your small intestine. In primary sclerosing cholangitis, inflammation causes scars within the bile ducts. These scars make the ducts hard and narrow and gradually cause serious liver damage. In most people with primary sclerosing cholangitis, the disease progresses slowly and can lead to liver failure, repeated infections, and tumors of the bile duct or liver. Liver transplant is the only known cure for primary sclerosing cholangitis. The search for other treatments to slow or stop primary sclerosing cholangitis is ongoing, and scientists have turned up many promising leads. Until better treatments are proved safe and effective, though, care for primary sclerosing cholangitis focuses on monitoring liver function, managing symptoms and, when possible, doing procedures that temporarily open blocked bile ducts.
The Urinary System is a group of organs in the body concerned with filtering out excess fluid and other substances from the bloodstream. The substances are filtered out from the body in the form of urine. Urine is a liquid produced by the kidneys, collected in the bladder and excreted through the urethra.
Finger metacarpophalangeal (MCP) joint collateral ligament sprains should not be overtreated. First-degree sprains may require a brief period of protection, usually consisting of buddy taping for 2-3 weeks. Second-degree sprains are immobilized in mid flexion for 3 weeks. Finger MCP joint hyperextension injuries may be treated by gently flexing the proximal phalanx and immobilizing the MCP joint in 30° of flexion for 2-3 weeks. A dorsal extension-block splint protects the healing volar plate while allowing active flexion of the finger. Early protected motion minimizes postinjury stiffness. Thumb MCP joint hyperextension injuries ("locked MCP joint") are immobilized in 20° MCP joint flexion for 3 weeks.
A leg ulcer is simply a break in the skin of the leg, which allows air and bacteria to get into the underlying tissue. This is usually caused by an injury, often a minor one that breaks the skin. In most people such an injury will heal up without difficulty within a week or two. However, when there is an underlying problem the skin does not heal and the area of breakdown can increase in size. This is a chronic leg ulcer.
Massive bone defects (>8 cm) will not unite without an additional intervention. They require a predictable, durable, and efficient method to regrow bone. The Ilizarov method of tension stress, or distraction osteogenesis, first involves a low-energy osteotomy1 - 5. The bone segments are then pulled apart, most often using an external device at a specific rate and rhythm (distraction phase), after which the newly formed bone (the regenerate) requires time for consolidation. The consolidation phase is variable and usually requires a substantially greater amount of time before the external device can be removed. Our technique of tibial bone transport over an intramedullary nail using cable and pulleys combines internal and external fixation, allowing the external fixator to be removed at the end of the distraction phase. This increases the efficiency of limb reconstruction and decreases the external-fixator-associated complications.
minimally invasive procedure is the new gold standard for hemorrhoidectomy, according to American and European experts in the field. The procedure, known as PPH (procedure for prolapse and hemorrhoids) stapled hemorrhoidectomy, combines hemorrhoidal devascularization and repositioning to return the veins to the anal canal. “This year, this is the revolutionary new procedure in the United States,” Gary Hoffman, MD, clinical faculty member in general and colorectal surgery, Cedars-Sinai Medical Center, Los Angeles, told General Surgery News after moderating a live PPH telesurgery at the 2003 annual meeting of the Society of American Gastrointestinal Endoscopic Surgeons.
