Causes of Headaches
Causes of Headaches samer kareem 2,422 Views • 2 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

Mitral Valve Surgery
Mitral Valve Surgery samer kareem 1,713 Views • 2 years ago

Mitral valve surgery is surgery to either repair or replace the mitral valve in your heart. Blood flows from the lungs and enters a pumping chamber of the heart called the left atrium. The blood then flows into the final pumping chamber of the heart called the left ventricle. The mitral valve is located between these two chambers. It makes sure that the blood keeps moving forward through the heart. You may need surgery on your mitral valve if: The mitral valve is hardened (calcified). This prevents blood from moving forward through the valve. The mitral valve is too loose. Blood tends to flows backward when this occurs. Minimally invasive mitral valve surgery is done through several small cuts. Another type of operation, open mitral valve surgery requires a larger cut.

Heart transplantation
Heart transplantation samer kareem 2,264 Views • 2 years ago

Finding a donor heart can be difficult. The heart must be donated by someone who is brain-dead but is still on life support. The donor heart must be matched as closely as possible to your tissue type to reduce the chance that your body will reject it. You are put into a deep sleep with general anesthesia, and a cut is made through the breastbone. Your blood flows through a heart-lung bypass machine while the surgeon works on your heart. This machine does the work of your heart and lungs while they are stopped, and supplies your body with blood and oxygen. Your diseased heart is removed and the donor heart is stitched in place. The heart-lung machine is then disconnected. Blood flows through the transplanted heart, which takes over supplying your body with blood and oxygen. Tubes are inserted to drain air, fluid, and blood out of the chest for several days, and to allow the lungs to fully re-expand.

Newborn Jaundice
Newborn Jaundice samer kareem 2,520 Views • 2 years ago

Infant jaundice is a yellow discoloration in a newborn baby's skin and eyes. Infant jaundice occurs because the baby's blood contains an excess of bilirubin (bil-ih-ROO-bin), a yellow-colored pigment of red blood cells. Infant jaundice is a common condition, particularly in babies born before 38 weeks gestation (preterm babies) and some breast-fed babies. Infant jaundice usually occurs because a baby's liver isn't mature enough to get rid of bilirubin in the bloodstream. In some cases, an underlying disease may cause jaundice. Treatment of infant jaundice often isn't necessary, and most cases that need treatment respond well to noninvasive therapy. Although complications are rare, a high bilirubin level associated with severe infant jaundice or inadequately treated jaundice may cause brain damage.

Polycythemia Vera
Polycythemia Vera samer kareem 2,610 Views • 2 years ago

This video: Polycythemia vera (pol-e-sigh-THEE-me-uh VEER-uh) is a slow-growing type of blood cancer in which your bone marrow makes too many red blood cells. Polycythemia vera may also result in production of too many of the other types of blood cells — white blood cells and platelets. These excess cells thicken your blood and cause complications, such as such as a risk of blood clots or bleeding. Polycythemia vera isn't common. It usually develops slowly, and you may have it for years without noticing signs or symptoms. Often, polycythemia vera is found during a blood test done for some other reason. Without treatment, polycythemia vera can be life-threatening. However, with proper medical care, many people experience few problems related to this disease. Over time, there's a risk of progressing to more-serious blood cancers, such as myelofibrosis or acute leukemia.

Frozen Shoulder Surgery
Frozen Shoulder Surgery samer kareem 5,115 Views • 2 years ago

Most frozen shoulders get better on their own within 12 to 18 months. For persistent symptoms, your doctor may suggest: Steroid injections. Injecting corticosteroids into your shoulder joint may help decrease pain and improve shoulder mobility, especially in the early stages of the process. Joint distension. Injecting sterile water into the joint capsule can help stretch the tissue and make it easier to move the joint. Shoulder manipulation.

Are you getting enough vitamin B12? Many people don’t, and that deficiency can cause some serious problems. Vitamin B12 does a lot of things for your body. It helps make your DNA and your red blood cells, for examples. Since your body doesn't make vitamin B12, you'll need to get it from animal-based foods or from supplements, and it needs to be consumed on a regular basis. Exactly how much you need and where you should get it from depends on things like your age, the diet you follow, your medical conditions, and in some cases what medications you take.

False Pregnancy in Women
False Pregnancy in Women samer kareem 5,461 Views • 2 years ago

The physical signs of pregnancy are easy to recognize -- nausea, fatigue, that swollen belly and (often) a healthy glow. But what if you had these telltale pregnancy symptoms -- and weren't actually pregnant? As crazy as it sounds, it does happen. False pregnancy, or pseudocyesis, is a condition in which a woman believes that she's pregnant, yet conception hasn't taken place and no baby is forming inside. Common, and often lasting, pregnancy symptoms help to reinforce this idea, which can lead a woman to be absolutely certain she's expecting, for months or even years!

Perineal Repair
Perineal Repair samer kareem 15,280 Views • 2 years ago

Perineal repair after episiotomy or spontaneous obstetric laceration is one of the most common surgical procedures. Potential sequelae of obstetric perineal lacerations include chronic perineal pain,1 dyspareunia,2 and urinary and fecal incontinence.3–5 Few studies of laceration repair techniques exist to support the development of an evidence-based approach to perineal repair. This article discusses a repair method that emphasizes anatomic detail, with the expectation that an anatomically correct perineal repair may result in a better long-term functional outcome.
