External Jugular Vein IV
External Jugular Vein IV samer kareem 8,084 Views • 2 years ago

External jugular vein cannulation is an integral part of modern medicine and is practiced in virtually every health care setting. Venous access allows sampling of blood, as well as administration of fluids, medications, parenteral nutrition, chemotherapy, and blood products. [1] This topic describes placement of an intravenous (IV) catheter into the external jugular vein. A similar technique can be used for placement of IV catheters at different anatomic sites.

Niemann-Pick Disease
Niemann-Pick Disease samer kareem 1,597 Views • 2 years ago

Niemann-Pick disease is a condition that affects many body systems. It has a wide range of symptoms that vary in severity. Niemann-Pick disease is divided into four main types: type A, type B, type C1, and type C2. These types are classified on the basis of genetic cause and the signs and symptoms of the condition. Infants with Niemann-Pick disease type A usually develop an enlarged liver and spleen (hepatosplenomegaly) by age 3 months and fail to gain weight and grow at the expected rate (failure to thrive). The affected children develop normally until around age 1 year when they experience a progressive loss of mental abilities and movement (psychomotor regression). Children with Niemann-Pick disease type A also develop widespread lung damage (interstitial lung disease) that can cause recurrent lung infections and eventually lead to respiratory failure. All affected children have an eye abnormality called a cherry-red spot, which can be identified with an eye examination. Children with Niemann-Pick disease type A generally do not survive past early childhood.

The development of the gastrointestinal tract
The development of the gastrointestinal tract samer kareem 2,524 Views • 2 years ago

The gastrointestinal tract (GIT) arises initially during the process of gastrulation from the endoderm of the trilaminar embryo (week 3) and extends from the buccopharyngeal membrane to the cloacal membrane. The tract and associated organs later have contributions from all the germ cell layers. During the 4th week three distinct regions (fore-, mid- and hind-gut) extend the length of the embryo and will contribute different components of the GIT. The large mid-gut is generated by lateral embryonic folding which "pinches off" a pocket of the yolk sac, the 2 compartments continue to communicate through the vitelline duct. The oral cavity (mouth) is formed following breakdown of the buccopharyngeal membrane (oropharyngeal or oral membrane) and contributed to mainly by the pharynx lying within the pharyngeal arches (More? Head Development). Loss of buccopharyngeal membrane opens the tract to amniotic fluid through the remainder of development, and during the fetal period is actively swallowed.

BENIGN  LIVER TUMORS
BENIGN LIVER TUMORS samer kareem 5,621 Views • 2 years ago

This form of liver cancer is called primary liver cancer. Noncancerous, or benign, liver tumors are common. They do not spread to other areas of the body, and they usually do not pose a serious health risk. In most cases, benign liver tumors are not detected because they cause no symptoms.

Methotrexate for Rheumatoid Arthritis
Methotrexate for Rheumatoid Arthritis samer kareem 1,698 Views • 2 years ago

Methotrexate works by reducing the function of the cells that are causing inflammation in the joint tissues. "Its use can reduce inflammation and therefore should help relieve pain and protect from joint damage," notes Sean A. Whelton, MD, a rheumatologist and associate professor of medicine at MedStar Georgetown University Hospital in Washington, D.C. Less inflammation in the joints should mean less joint pain and less joint swelling. You should also feel less fatigue and less morning stiffness.

Dementia is the name for a group of symptoms that commonly include problems with memory, thinking, problem solving, language and perception. In a person with dementia, these symptoms are bad enough to affect daily life.

Massive Hemothorax
Massive Hemothorax samer kareem 1,545 Views • 2 years ago

Hemothorax is the presence of blood in the pleural space. The source of blood may be the chest wall, lung parenchyma, heart, or great vessels. Although some authors state that a hematocrit value of at least 50% is necessary to differentiate a hemothorax from a bloody pleural effusion, most do not agree on any specific distinction. Hemothorax is usually a consequence of blunt or penetrating trauma. Much less commonly, it may be a complication of disease, may be iatrogenically induced, [1] or may develop spontaneously. [2] Prompt identification and treatment of traumatic hemothorax is an essential part of the care of the injured patient. The upright chest radiograph is the ideal primary diagnostic study in the evaluation of hemothorax (see Workup). In cases of hemothorax unrelated to trauma, a careful investigation for the underlying source must be performed while treatment is provided.

Early Signs of Liver Damage

As the liver becomes more severely damaged, more obvious and serious symptoms can develop, such as: yellowing of the skin and whites of the eyes (jaundice) swelling in the legs, ankles and feet, due to a build-up of fluid (oedema)

Warning: Diabetic Ulcer Debridement
Warning: Diabetic Ulcer Debridement Scott 16,868 Views • 2 years ago

Debridement is the removal of necrotic tissue, foreign debris, bacterial growth, callus, wound edge, and wound bed tissue from chronic wounds in order to stimulate the wound healing process. Stimulation of wound healing mediated by debridement is thought to occur by the conversion of a chronic non-healing wound environment to an acute healing environment through the removal of cells that are not responsive to endogenous healing stimuli. Debridement is used commonly in standard wound treatment of diabetic foot ulcers (DFUs). Methods of debridement include surgery (sharp debridement), chemical debridement (antiseptics, polysaccharide beads, pastes), autolytic (hydrogels, hydrocolloids and transparent films), biosurgery (maggots), mechanical (hydrodebridement), and biochemical debridement (enzyme preparations). Callus is a buildup of keratinized skin formed under conditions of repeated pressure or friction and may contribute to ulcer formation by creating focal areas of high plantar pressure. The debridement of callus has been proposed to be relevant for both treatment and prevention of DFU. The purpose of this report is to retrieve and review existing evidence of comparative clinical effectiveness of different methods of debridement for the treatment of DFUs. Additionally examined in this report is the clinical effectiveness for treatment and prevention of DFU using callus debridement. Cost-effectiveness, and existing debridement guidelines for the treatment of DFUs will also be reviewed.

Upper GI Bleed
Upper GI Bleed samer kareem 1,783 Views • 2 years ago

This could be caused by an infection, food poisoning, parasites, Crohn's disease, or reduced blood flow in the colon. Hemorrhoids are another common cause of GI or rectal bleeding. A hemorrhoid is an enlarged vein in your rectum or anus. These enlarged veins can rupture and bleed, causing rectal bleeding.

Reduction Coil Treatment of emphysema
Reduction Coil Treatment of emphysema samer kareem 1,646 Views • 2 years ago

Emphysema gradually damages the air sacs (alveoli) in your lungs, making you progressively more short of breath. Emphysema is one of several diseases known collectively as chronic obstructive pulmonary disease Smoking is the leading cause of emphysema. Your lungs' alveoli are clustered like bunches of grapes. In emphysema, the inner walls of the air sacs weaken and eventually rupture — creating one larger air space instead of many small ones. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream. When you exhale, the damaged alveoli don't work properly and old air becomes trapped, leaving no room for fresh, oxygen-rich air to enter. Treatment may slow the progression of emphysema, but it can't reverse the damage.

Pulmonary Circulation
Pulmonary Circulation samer kareem 8,636 Views • 2 years ago

Pulmonary circulation is the portion of the cardiovascular system which carries deoxygenated blood away from the heart, to the lungs, and returns oxygenated (oxygen-rich) blood back to the heart. The function of pulmonary circulation is to exchange carbon dioxide for oxygen in the blood. It is the passage of blood from the heart to the capillaries of the lungs, where the gases are exchanged, and back to the heart to be pumped around the body.

Acute aortic thrombosis
Acute aortic thrombosis samer kareem 1,946 Views • 2 years ago

The increased risk of thrombosis in patients with active cancer has multiple causes. Acute thrombosis of the aorta is an exceedingly rare but potentially devastating complication in patients with cancer receiving cisplatin-based chemotherapy. Prompt diagnosis and definitive treatment are imperative to decrease morbidity and mortality. Early diagnosis is difficult because initial presentation is often nonspecific, requiring a high degree of clinical suspicion. We report 4 cases of acute thrombosis of the abdominal aorta in patients with cancer receiving cisplatin-based chemotherapy. We review the clinical aspects, recommended investigation, and treatment of this potentially fatal complication.

The fetal circulation is the circulatory system of a human fetus, often encompassing the entire fetoplacental circulation that also includes the umbilical cord and the blood vessels within the placenta that carry fetal blood.

The fetal circulation works differently from that of born humans, mainly because the lungs are not in use: the fetus obtains oxygen and nutrients from the mother through the placenta and the umbilical cord.
