Frozen Shoulder
Frozen Shoulder samer kareem 1,664 Views • 3 years ago

The bones, ligaments and tendons that make up your shoulder joint are encased in a capsule of connective tissue. Frozen shoulder occurs when this capsule thickens and tightens around the shoulder joint, restricting its movement. Doctors aren't sure why this happens to some people, although it's more likely to occur in people who have diabetes or those who recently had to immobilize their shoulder for a long period, such as after surgery or an arm fracture.

Ventricular Tachycardia
Ventricular Tachycardia samer kareem 3,008 Views • 3 years ago

Ventricular tachycardia is a type of heart rhythm disorder (arrhythmia) in which the lower chambers of your heart (ventricles) beat very quickly because of a problem in your heart's electrical system. In ventricular tachycardia, your heart may not be able to pump enough blood to your body and lungs because the chambers are beating so fast that they don't have time to properly fill. Ventricular tachycardia may be brief — lasting for just seconds and often not causing symptoms — or it can last for much longer, and you can develop symptoms such as dizziness or lightheadedness, or you can even pass out. This condition usually occurs in people with other heart conditions, such as coronary artery disease, cardiomyopathy and some types of valvular heart disease. Ventricular tachycardia may lead to a condition in which your lower heart chambers quiver (ventricular fibrillation), which may cause your heart to stop (sudden cardiac arrest) and lead to death if not treated immediately. Ventricular tachycardia can also cause your heart to stop, especially if the heart is beating very quickly, if it's lasting for a long period, and if you have an underlying heart condition.

Atrial flutter

Atrial flutter (AFL) is a type of abnormal heart rate, or arrhythmia. It occurs when the upper chambers of your heart beat too fast. When the chambers in the top of your heart (atria) beat faster than the bottom ones (ventricles), it complicates your heart rhythm

Tuberculosis
Tuberculosis samer kareem 13,324 Views • 3 years ago

Tuberculosis (TB) is a disease caused by bacteria called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but they can also damage other parts of the body. TB spreads through the air when a person with TB of the lungs or throat coughs, sneezes, or talks. If you have been exposed, you should go to your doctor for tests. You are more likely to get TB if you have a weak immune system. Symptoms of TB in the lungs may include A bad cough that lasts 3 weeks or longer Weight loss Loss of appetite Coughing up blood or mucus Weakness or fatigue Fever Night sweats

MRI of Cervical Stenosis samer kareem 2,301 Views • 3 years ago

Cervical Stenosis Cervical Spinal Stenosis Video Spinal stenosis pain in the neck is called cervical spinal stenosis. This condition means that there is potential compression of the spinal cord. Unfortunately, the spinal cord compression can lead to serious problems such as extreme weakness, or even paralysis. With cervical stenosis, anyone who develops signs of spinal cord compression (myelopathy) may need more invasive treatment, such as surgery.

Causes of Headaches
Causes of Headaches samer kareem 2,462 Views • 3 years ago

Your headache symptoms can help your doctor determine its cause and the appropriate treatment. Most headaches aren't the result of a serious illness, but some may result from a life-threatening condition requiring emergency care. Headaches are generally classified by cause: Primary headaches A primary headache is caused by overactivity of or problems with pain-sensitive structures in your head. A primary headache isn't a symptom of an underlying disease. Chemical activity in your brain, the nerves or blood vessels surrounding your skull, or the muscles of your head and neck (or some combination of these factors) can play a role in primary headaches. Some people may also carry genes that make them more likely to develop such headaches. The most common primary headaches are: Cluster headache Migraine (with and without aura) Tension headache (also known as tension-type headache) Trigeminal autonomic cephalalgia (TAC), such as cluster headache and paroxysmal hemicrania A few headache patterns also are generally considered types of primary headache, but are less common. These headaches have distinct features, such as an unusual duration or pain associated with a certain activity. Although generally considered primary, each could be a symptom of an underlying disease. They include: Chronic daily headaches (for example, chronic migraine, chronic tension-type headache, or hemicranias continua) Cough headaches Exercise headaches Sex headaches Some primary headaches can be triggered by lifestyle factors, including: Alcohol, particularly red wine Certain foods, such as processed meats that contain nitrates Changes in sleep or lack of sleep Poor posture Skipped meals Stress Secondary headaches A secondary headache is a symptom of a disease that can activate the pain-sensitive nerves of the head. Any number of conditions — varying greatly in severity — may cause secondary headaches. Possible causes of secondary headaches include: Acute sinusitis Arterial tears (carotid or vertebral dissections) Blood clot (venous thrombosis) within the brain — separate from stroke Brain aneurysm (a bulge in an artery in your brain) Brain AVM (brain arteriovenous malformation) — an abnormal formation of brain blood vessels Brain tumor Carbon monoxide poisoning Chiari malformation (structural problem at the base of your skull) Concussion Dehydration Dental problems Ear infection (middle ear) Encephalitis (brain inflammation) Giant cell arteritis (inflammation of the lining of the arteries) Glaucoma (acute angle closure glaucoma) Hangovers

Pacemakers & Implantable Defibrillators
Pacemakers & Implantable Defibrillators samer kareem 2,458 Views • 3 years ago

ICDs are useful in preventing sudden death in patients with known, sustained ventricular tachycardia or fibrillation. Studies have shown ICDs to have a role in preventing cardiac arrest in high-risk patients who haven't had, but are at risk for, life-threatening ventricular arrhythmias. View an animation of an ICD. Newer-generation ICDs may have a dual function which includes the ability to serve as a pacemaker. The pacemaker feature would stimulate the heart to beat if the heart rate is detected to be too slow. What is an Implantable Cardioverter Defibrillator (ICD)? An ICD is a battery-powered device placed under the skin that keeps track of your heart rate. Thin wires connect the ICD to your heart. If an abnormal heart rhythm is detected the device will deliver an electric shock to restore a normal heartbeat if your heart is beating chaotically and much too fast. ICDs have been very useful in preventing sudden death in patients with known, sustained ventricular tachycardia or fibrillation. Studies have shown that they may have a role in preventing cardiac arrest in high-risk patients who haven't had, but are at risk for, life-threatening ventricular arrhythmias.

Quick Fingernail Test for Diabetes
Quick Fingernail Test for Diabetes samer kareem 83,383 Views • 3 years ago

A simple test of fingernail clippings could replace a blood draw as a way to diagnose and monitor type 2 diabetes mellitus (T2DM), with huge implications for tracking the disease in the developing world. Research on this method by a team of Belgian researchers was reported July 28, 2015, at the 2015 American Association for Clinical Chemistry (AACC) Annual Meeting and Clinical Lab Expo in Atlanta. The team, led by Joris R. Delanghe, MD, PhD, of the Department of Global Chemistry, Microbiology and Immunology at Ghent University, collected nail clippings from 25 people with T2DM and 25 without the disease. The clippings were ground into a powder and tested with an inexpensive FT-IR photometer to measure how much the protein in the nails had bonded with sugar molecules, a process known as glycation. “We found a striking difference in the measurements between the control group and the patients with diabetes,” Delanghe said. In an interview with Evidence-Based Diabetes Management, he said replacing the standard blood test to measure glycated hemoglobin is a huge advantage. In many cultures, he said, “Taking blood is something that cannot be tolerated.” - See more at: http://www.ajmc.com/journals/evidence-based-diabetes-management/2015/september-2015/fingernail-tests-may-offer-cheap-simple-way-to-diagnose-diabetes#sthash.XQxnBcNO.dpuf

Marfan Syndrome Diagnosis and Treatment
Marfan Syndrome Diagnosis and Treatment samer kareem 9,852 Views • 3 years ago

Marfan syndrome is a genetic disorder that affects the body’s connective tissue. Connective tissue holds all the body’s cells, organs and tissue together. It also plays an important role in helping the body grow and develop properly. marfan_general_2.jpg What is Marfan Syndrome?Connective tissue is made up of proteins. The protein that plays a role in Marfan syndrome is called fibrillin-1. Marfan syndrome is caused by a defect (or mutation) in the gene that tells the body how to make fibrillin-1. This mutation results in an increase in a protein called transforming growth factor beta, or TGF-β. The increase in TGF-β causes problems in connective tissues throughout the body, which in turn creates the features and medical problems associated with Marfan syndrome and some related disorders. Because connective tissue is found throughout the body, Marfan syndrome can affect many different parts of the body, as well. Features of the disorder are most often found in the heart, blood vessels, bones, joints, and eyes. Some Marfan features – for example, aortic enlargement (expansion of the main blood vessel that carries blood away from the heart to the rest of the body) – can be life-threatening. The lungs, skin and nervous system may also be affected. Marfan syndrome does not affect intelligence.
