Coronary arteries

The heart receives its own supply of blood from the coronary arteries. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood.

Atrial Septal Defect
Atrial Septal Defect samer kareem 7,467 Visualizações • 2 anos atrás

atrial septal defect (ASD) is a hole in the wall between the two upper chambers of your heart (atria). The condition is present from birth (congenital). Small atrial septal defects may close on their own during infancy or early childhood. Large and long-standing atrial septal defects can damage your heart and lungs. Small defects may never cause a problem and may be found incidentally. An adult who has had an undetected atrial septal defect for decades may have a shortened life span from heart failure or high blood pressure that affects the arteries in the lungs (pulmonary hypertension). Surgery may be necessary to repair atrial septal defects to prevent complications

Controlled studies on treatment of catscratch disease (CSD) are lacking. Thus, treatment recommendations are based on case reports, reviews, a single controlled trial, and anecdotal data. Practice guidelines for the diagnosis and management of skin and soft-tissue infections, including CSD, have been established.Oct 19, 2016

An omphalocele is a birth defect in which an infant's intestine or other abdominal organs are outside of the body because of a hole in the belly button (navel) area. The intestines are covered only by a thin layer of tissue and can be easily seen.

Aortic Valve Tumor
Aortic Valve Tumor samer kareem 1,909 Visualizações • 2 anos atrás

Papillary fibroelastoma is the third most common primary tumor of the heart and is most likely to involve the cardiac valves. Like myxomas, they arise from the endocardium in most patients and since these tumors are often incidental findings at echocardiography or autopsy, the true incidence is difficult to estimate. Most patients are older than 60 years, which also contrasts with myxomas. Papillary fibroelastomas can embolize, leading to severe neurological complications and therefore, surgical removal is advised, although there is controversy regarding small incidental lesions and the need for surgery.

Ruptured Liver Abscess
Ruptured Liver Abscess samer kareem 9,108 Visualizações • 2 anos atrás

A liver abscess is a pus-filled mass inside the liver. Common causes are abdominal infections such as appendicitis or diverticulitis due to haematogenous spread through the portal vein. A pyogenic liver abscess (PLA) is a pocket of pus that forms in the liver in response to an infection or trauma. Pus is a fluid composed of white blood cells, dead cells, and bacteria that forms when your body fights off infection.Dec 11, 2015

Microvilli
Microvilli samer kareem 2,049 Visualizações • 2 anos atrás

Cells may have slender extensions of the cell membrane to form cilia or the smaller extensions called microvilli. The microscopic microvilli effectively increase the surface area of the cell and are useful for absorption and secretion functions. A dramatic example is the human small intestine. The tissue has small fingerlike extensions called villi which are collections of cells, and those cells have many microvilli to even further increase the available surface area for the digestion process. According to Audesirk & Audesirk, this can give an effective surface area of about 250 square meters for absorption.

Diabetes Pathophysiology

When food is taken, it is broken down into smaller components. Sugars and carbohydrates are thus broken down into glucose for the body to utilize them as an energy source. The liver is also able to manufacture glucose. In normal persons the hormone insulin, which is made by the beta cells of the pancreas, regulates how much glucose is in the blood. When there is excess of glucose in blood, insulin stimulates cells to absorb enough glucose from the blood for the energy that they need. Insulin also stimulates the liver to absorb and store any excess glucose that is in the blood. Insulin release is triggered after a meal when there is a rise in blood glucose. When blood glucose levels fall, during exercise for example, insulin levels fall too. High insulin will promote glucose uptake, glycolysis (break down of glucose), and glycogenesis (formation of storage form of glucose called glycogen), as well as uptake and synthesis of amino acids, proteins, and fat. Low insulin will promote gluconeogenesis (breakdown of various substrates to release glucose), glycogenolysis (breakdown of glycogen to release gluose), lipolysis (breakdown of lipids to release glucose), and proteolysis (breakdown of proteins to release glucose). Insulin acts via insulin receptors.

Mastectomy
Mastectomy samer kareem 83,850 Visualizações • 2 anos atrás

Mastectomy is surgery to remove all breast tissue from a breast as a way to treat or prevent breast cancer. For those with early-stage breast cancer, mastectomy may be one treatment option. Breast-conserving surgery (lumpectomy), in which only the tumor is removed from the breast, may be another option.

A modified radical mastectomy is a procedure in which the entire breast is removed, including the skin, areola, nipple, and most axillary lymph nodes; the pectoralis major muscle is spared. Historically, a modified radical mastectomy was the primary method of treatment of breast cancer. [1, 2] As the treatment of breast cancer evolved, breast conservation has become more widely used. [3, 4] However, mastectomy still remains a viable option for women with breast cancer. [5, 6]

Research from Mayo Clinic finds that half of elderly patients who start dialysis after age 75 will die within one year.

Lead study author and a health care delivery scholar with the Mayo Clinic Robert D. and Patricia E. Kern Center for the Science of Health Care Delivery, Dr. Bjorg Thorsteinsdottir says many elderly patients and their families feel that they have no choice but to start dialysis, with several expressing regret from having initiated therapy.

The findings were presented at the American Society of Nephrology's Kidney Week 2013 in Atlanta.
