Prompt treatment to break up the clot greatly reduces the risk of death. This can be done with blood thinners and drugs or procedures. Compression stockings and physical activity can help prevent clots from forming in the first place.

Acute kidney injury: mechanism, diagnosis and management
Acute kidney injury: mechanism, diagnosis and management samer kareem 1,539 Views • 3 years ago

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.

Bone Scan Introduction
Bone Scan Introduction Mohamed 18,004 Views • 3 years ago

A Bone scan or bone scintigraphy is a nuclear scanning test to find certain abnormalities in bone which are triggering the bone's attempts to heal. It is primarily used to help diagnose a number of conditions relating to bones, including: cancer of the bone or cancers that have spread (metastasized) to the bone, locating some sources of bone inflammation (e.g. bone pain such as lower back pain due to a fracture), the diagnosis of fractures that may not be visible in traditional X-ray images, and the detection of damage to bones due to certain infections and other problems.

Nuclear medicine bone scans are one of a number of methods of bone imaging, all of which are used to visually detect bone abnormalities. Such imaging studies include magnetic resonance imaging (MRI), X-ray computed tomography (CT) and in the case of 'bone scans' nuclear medicine. However, a nuclear bone scan is a functional test, which means it measures an aspect of bone metabolism, which most other imaging techniques cannot. The nuclear bone scan competes with the FDG-PET scan in seeing abnormal metabolism in bones, but it is considerably less expensive.

Nuclear bone scans are not to be confused with the completely different test often termed a "bone density scan," DEXA or DXA, which is a low exposure X-ray test measuring bone density to look for osteoporosis and other diseases where bones lose mass, without any bone re-building activity. The nuclear medicine scan technique is sensitive to areas of unusual bone re-building activity because the radiopharmaceutical is taken up by osteoblast cells which build bone. The technique therefore is sensitive to fractures and bone reaction to infections and bone tumors, including tumor metastases to bones, because all these pathologies trigger bone osteoblast activity. The bone scan is not sensitive to osteoporosis or multiple myeloma in bones, and therefore other techniques must be used to assess bone abnormalities from these diseases.

A good starting point for any scientist in any field is to recognize that there is much we do not know. We do not know, for example, why there is more matter than antimatter in the universe. We do not know very well how the evolution of the dinosaurs filtered out. And, perhaps most surprising of all is that we do not know very well how many organs the human body has or what all its functions are.

A coma is a prolonged state of unconsciousness. During a coma, a person is unresponsive to his or her environment. The person is alive and looks like he or she is sleeping. However, unlike in a deep sleep, the person cannot be awakened by any stimulation, including pain.

An appendectomy (sometimes called appendisectomy or appendicectomy (British English)) is the surgical removal of the vermiform appendix. This procedure is normally performed as an emergency procedure, when the patient is suffering from acute appendicitis. In the absence of surgical facilities, intravenous antibiotics are used to delay or prevent the onset of sepsis; it is now recognized that many cases will resolve when treated perioperatively. In some cases the appendicitis resolves completely; more often, an inflammatory mass forms around the appendix, causing transruptural flotation. This is a relative contraindication to surgery.

Ventricular septal defect (VSD)
Ventricular septal defect (VSD) samer kareem 3,291 Views • 3 years ago

A ventricular septal defect (VSD), a hole in the heart, is a common heart defect that's present at birth (congenital). The hole occurs in the wall that separates the heart's lower chambers (septum) and allows blood to pass from the left to the right side of the heart. The oxygen-rich blood then gets pumped back to the lungs instead of out to the body, causing the heart to work harder. A small ventricular septal defect may cause no problems, and many small VSDs close on their own. Larger VSDs need surgical repair early in life to prevent complications.

Living with Tourette Syndrome
Living with Tourette Syndrome samer kareem 7,282 Views • 3 years ago

The cause for TS is unknown. Early research suggested that TS is an inherited condition (often, the person's near or distant relatives have had some form of transient or chronic tic disorder or associated symptoms). Recent studies point to a combination of environmental and genetic factors as a cause of the disorder. The specific genes involved in the development of TS are still being investigated. Studies suggest that TS has a neurological basis and results from an abnormality which affects the brain's metabolism of certain neurotransmitters (chemicals in the brain that regulate behavior.) Current research being funded by the Tourette Syndrome Association (TSA) will help provide more information about the causes and genetic factors of TS.

An estimated 12,500 spinal cord injuries occur in the U.S. every year, leaving the injured people, their friends, and their family, to cope with the aftermath of the catastrophe. For many, navigating the challenges of the health care system can feel a bit like going to medical school. Suddenly you're learning a veritable cornucopia of new terms, and may be spending endless hours Googling spinal cord anatomy to fill in the gaps in your knowledge. An educated patient is better equipped to advocate for his or her needs and interests. An education in spinal cord anatomy helps you understand what your doctor is saying, ask intelligent questions, and detect medical errors before they endanger your health.

Microscopic polyangiitis (MPA) is vasculitis of small vessels. It was initially considered as a microscopic form of polyarteritis nodosa (PAN). In 1990, the American College of Rheumatology developed classification criteria for several types of systemic vasculitis but did not distinguish between polyarteritis nodosa and microscopic polyarteritis nodosa. [1] In 1994, a group of experts held an international consensus conference in Chapel Hill, North Carolina, to attempt to redefine the classification of small vessel vasculitides. [2, 3]
