Bladder cancer
Bladder cancer samer kareem 11,292 Views • 3 years ago

The bladder is a hollow organ in the lower abdomen (pelvis). It collects and stores urine produced by the kidneys. The bladder is connected to the kidneys by a tube from each kidney called a ureter. When the bladder reaches its capacity of urine, the bladder wall contracts, although adults have voluntary control over the timing of this contraction. At the same time, a urinary control muscle (sphincter) in the urethra relaxes. The urine is then expelled from the bladder. The urine flows through a narrow tube called the urethra and leaves the body. This process is called urination, or micturition.

Rheumatic Heart Disease
Rheumatic Heart Disease samer kareem 4,615 Views • 3 years ago

Rheumatic heart disease (RHD) is the most common acquired heart disease in children in many countries of the world, especially in developing countries. The global burden of disease caused by rheumatic fever currently falls disproportionately on children living in the developing world, especially where poverty is widespread. RHD is a chronic heart condition caused by rheumatic fever that can be prevented and controlled. Rheumatic fever is caused by a preceding group A streptococcal (strep) infection. Treating strep throat with antibiotics can prevent rheumatic fever. Moreover, regular antibiotics (usually monthly injections) can prevent patients with rheumatic fever from contracting further strep infections and causing progression of valve damage. Consequences of rheumatic heart disease Acute rheumatic fever primarily affects the heart, joints and central nervous system. The major importance of acute rheumatic fever is its ability to cause fibrosis of heart valves, leading to crippling valvular heart disease, heart failure and death. The decline of rheumatic fever in developed countries is believed to be the result of improved living conditions and availability of antibiotics for treatment of group A streptococcal infection. Overcrowding, poor housing conditions, undernutrition and lack of access to healthcare play a role in the persistence of this disease in developing countries.

With bone marrow disease, there are problems with the stem cells or how they develop: In leukemia, a cancer of the blood, the bone marrow makes abnormal white blood cells. In aplastic anemia, the bone marrow doesn't make red blood cells. In myeloproliferative disorders, the bone marrow makes too many white blood cells.Nov 22, 2016

Familial Hypocalciuric Hypercalcemia
Familial Hypocalciuric Hypercalcemia samer kareem 4,378 Views • 3 years ago

There are 3 genetic types of FHH based on chromosome location. FHH type 1 accounts for 65% of cases and is due to inactivating mutations in the CASR gene, localized to 3q21.1. This gene encodes the calcium-sensing receptor (CaSR). Loss of CaSR function results in a reduction in the sensitivity of parathyroid and renal cells to calcium levels so hypercalcemia is perceived as normal. The other 35% have either a mutation GNA11 (19p13.3) seen in FHH type 2 or AP2S1 (19q13.2-q13.3) seen in FHH type 3 (see these terms) or in genes not yet discovered. FHH is rarely caused by auto-antibodies against CaSR in those without a mutation.

A hemolytic transfusion reaction is a serious complication that can occur after a transfusion of blood. The red blood cells that were given in the transfusion are destroyed by the patient's immune system. There are other types of allergic transfusion reactions that do not cause hemolysis.

Your kidneys are two bean-shaped organs that lie just below your rib cage, on each side of your spine. They remove waste from your body, level out your blood pressure, and keep your bones strong. They also ensure that you have the right amount of chemicals, like potassium and sodium (salt), in your blood. Finally, they make the hormone that causes your body to create red blood cells.

Your body needs bile, but if it has too much cholesterol in it, that makes gallstones more likely. It can also happen if your gallbladder can't empty properly. Pigment stones are more common in people with certain medical conditions, such as cirrhosis (a liver disease) or blood diseases such as sickle cell anemia.

Snapping Scapula Syndrome

... Orthopedics & Sports Medicine Our Services Where Does it Hurt? SNAPPING SCAPULA SYNDROME PDF Icon PRINTABLE BOOKLET A PATIENT'S GUIDE TO SNAPPING SCAPULA SYNDROME INTRODUCTION The scapulothoracic joint is located where the shoulder blade (also called the scapula) glides along the chest wall (the thorax). When movement of this joint causes feelings or sounds of grating, grinding, popping, or thumping, doctors call it snapping scapula syndrome. Snapping scapula syndrome is fairly rare. When it happens, the soft tissues between the scapula and the chest wall are thick, irritated, or inflamed. Snapping scapula syndrome can also happen if the bones of the shoulder blade or rib cage grate over one another. This guide will help you understand what causes snapping scapula syndrome how doctors treat this condition ANATOMY What parts of the body are involved in this condition? The shoulder is made up of three bones: the humerus (upper arm bone), the clavicle (collarbone), and the scapula(shoulder blade). Two large muscles attach to the front part of the scapula where it rests against the chest wall. One of them, called the subscapularis muscle, attaches over the front of the scapula where it faces the chest wall. The serratus anterior muscle attaches along the edge of the scapula nearest the spine. It passes in front of the scapula, wraps around the chest wall, and connects to the ribs on the front part of the chest. A bursa is a fluid-filled sac that cushions body tissues from friction. A bursa sits between the two muscles of the scapula. There is also a bursa in the space between the serratus anterior muscle and the chest wall. When bursa sacs become inflamed, the condition is called bursitis. Scapulothoracic bursitis refers to inflammation in the bursa under the shoulder blade. This type of bursitis is most common in the upper corner of the scapula nearest the spine. It also occurs under the lower tip of the scapula. In either case, it can cause the sounds and sensations of snapping scapula syndrome. A person can have bursitis in the joint without any grinding or popping. Related Document: A Patient's Guide to Shoulder Anatomy CAUSES What causes this condition? Snapping scapula is caused by problems in the soft tissues or bones of the scapula and chest wall. It can start when the tissues between the scapula and shoulder blade thicken from inflammation. The inflammation is usually caused by repetitive movements. Certain motions of the shoulder done over and over again, such as the movements of pitching baseballs or hanging wallpaper, can cause the tissues of the joint to become inflamed. In other cases, the muscles under the scapula have shrunk (atrophied) from weakness or inactivity. The scapula bone then rides more closely to the rib cage. This means the scapula bumps or rubs on the rib bones during movement. Changes in the alignment or contour of the bones of the scapulothoracic joint can also cause snapping scapula. When a fractured rib or scapula isn't lined up just right, it can cause a bumpy ridge that produces the characteristic grind or snap as the scapula moves over the chest wall.
