Symptoms B12 deficiency
Symptoms B12 deficiency samer kareem 5,905 Views • 2 years ago

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.

Claudication, which is defined as reproducible ischemic muscle pain, is one of the most common manifestations of peripheral arterial occlusive disease (PAOD) caused by atherosclerosis. Claudication occurs during physical activity and is relieved after a short rest. Pain develops because of inadequate blood flow.

Retina Laser Surgery
Retina Laser Surgery samer kareem 1,455 Views • 2 years ago

Most retinal tears need to be treated by sealing the retina to the back wall of the eye with laser surgery or cryotherapy (a freezing treatment). Both of these procedures create a scar that helps seal the retina to the back of the eye. This prevents fluid from traveling through the tear and under the retina, which usually prevents the retina from detaching. These treatments cause little or no discomfort and may be performed in your ophthalmologist’s office. With laser surgery, your ophthalmologist uses a laser to make small burns around the retinal tear. The scarring that results seals the retina to the underlying tissue, helping to prevent a retinal detachment.

Bowel Obstruction
Bowel Obstruction samer kareem 1,860 Views • 2 years ago

A bowel obstruction happens when either your small or large intestine is partly or completely blocked. The blockage prevents food, fluids, and gas from moving through the intestines in the normal way. The blockage may cause severe pain that comes and goes. This topic covers a blockage caused by tumors, scar tissue, or twisting or narrowing of the intestines. It does not cover ileus, which most commonly happens after surgery on the belly (abdominal surgery). What causes a bowel obstruction? Tumors, scar tissue (adhesions), or twisting or narrowing of the intestines can cause a bowel obstruction. These are called mechanical obstructions . In the small intestine, scar tissue is most often the cause. Other causes include hernias and Crohn's disease, which can twist or narrow the intestine, and tumors, which can block the intestine. A blockage also can happen if one part of the intestine folds like a telescope into another part, which is called intussusception.

Colon and Rectal Cancer
Colon and Rectal Cancer samer kareem 10,114 Views • 2 years ago

Colorectal cancer (also known as colon cancer, rectal cancer or bowel cancer) is the development of cancer in the colon or rectum (parts of the large intestine). It is due to the abnormal growth of cells that have the ability to invade or spread to other parts of the body. People with HNPCC tend to develop colon cancer before age 50. Familial adenomatous polyposis (FAP). FAP is a rare disorder that causes you to develop thousands of polyps in the lining of your colon and rectum. People with untreated FAP have a greatly increased risk of developing colon cancer before age 40.

Sarcoidosis Features samer kareem 971 Views • 2 years ago

Sarcoidosis is an inflammatory disease that affects multiple organs in the body, but mostly the lungs and lymph glands. In people with sarcoidosis, abnormal masses or nodules (called granulomas) consisting of inflamed tissues form in certain organs of the body. These granulomas may alter the normal structure and possibly the function of the affected organ(s).

Iris Surgery
Iris Surgery samer kareem 6,825 Views • 2 years ago

Cosmetic iris implants have not been evaluated by any U.S. regulatory agency or tested for safety in clinical trials. While the implants are not approved by the U.S. Food and Drug Administration, it has been reported in the media this month that the surgery is being performed overseas. During iris implant surgery, an artificial iris made of silicone is folded and inserted into a slit that has been cut into the cornea. Then the iris is unfolded and adjusted to cover the natural iris. Local anesthesia is used.

Antiepileptics Drugs
Antiepileptics Drugs samer kareem 2,531 Views • 2 years ago

Modern treatment of seizures started in 1850 with the introduction of bromides, which was based on the theory that epilepsy was caused by an excessive sex drive. In 1910, phenobarbital (PHB), which then was used to induce sleep, was found to have antiseizure activity and became the drug of choice for many years. A number of medications similar to PHB were developed, including primidone.

Endoscopic Dacryocystorhinostomy
Endoscopic Dacryocystorhinostomy samer kareem 7,142 Views • 2 years ago

Dacryocystorhinostomy (DCR) is a procedure performed for the treatment of tearing (epiphora) due to blockage of the nasolacrimal duct. Tears originate in the lacrimal gland, located at the upper outer margin of the eye. As tears cross the eye with each blink, they are directed into small openings in the eyelids called puncta. From this point, tears travel through a pathway known as the canalicular system into the lacrimal sac. The lacrimal sac is located between the eye and the nose, and funnels tears into the nasal cavity through the nasolacrimal duct (Figure 1). As this is quite a long path for tears to travel, there can be many causes of excessive tearing. Blockage of the nasolacrimal duct is one common cause, and can be treated by creating a direct opening from the lacrimal sac into the nasal cavity in a procedure known as DCR. The evaluation and management of tearing may involve both an ophthalmologist and an otolaryngologist.

Moderate Nevus Removal
Moderate Nevus Removal samer kareem 1,006 Views • 2 years ago

Most people develop several moles (nevi) throughout adulthood. Moles can be found anywhere on the body, usually in sun-exposed areas, and are usually brown, smooth, and slightly raised. In most cases, a nevus is benign and doesn't require treatment. Rarely, they turn into melanoma or other skin cancers. A nevus that changes shape, grows bigger, or darkens should be evaluated for removal.

Vomiting and Diarrhea in Kids
Vomiting and Diarrhea in Kids samer kareem 4,996 Views • 2 years ago

Diarrhea in Children: Common Causes and Treatments Diarrhea is the body's way of ridding itself of germs, and most episodes last a few days to a week. Diarrhea often occurs with fever, nausea, vomiting, cramps, and dehydration. Some of the most common reasons kids get diarrhea include: Infection from viruses like rotavirus, bacteria like salmonella and, rarely, parasites like giardia. Viruses are the most common cause of a child's diarrhea. Along with loose or watery stools, symptoms of a viral gastroenteritis infection often include vomiting, stomachache, headache, and fever. When treating viral gastroenteritis -- which can last 5-14 days -- it's important to prevent fluid loss. Offer additional breast milk or an oral rehydration solution (ORS) to infants and young children. Water alone doesn't have enough sodium, potassium, and other nutrients to safely rehydrate very young children. Be sure to talk to your doctor about the amount of fluids your child needs, how to make sure he or she gets them, when to give them, and how to watch for dehydration. Older children with diarrhea can drink anything they like to stay hydrated, including ORS and brand-name products (their names usually end in "lyte"). Popsicles can also be a good way to get fluids into a child who's been vomiting and needs to rehydrate slowly.

Emergency Pericardiocentesis
Emergency Pericardiocentesis samer kareem 7,825 Views • 2 years ago

Pericardiocentesis is the aspiration of fluid from the pericardial space that surrounds the heart. This procedure can be life saving in patients with cardiac tamponade, even when it complicates acute type A aortic dissection and when cardiothoracic surgery is not available. [1] Cardiac tamponade is a time sensitive, life-threatening condition that requires prompt diagnosis and management. Historically, the diagnosis of cardiac tamponade has been based on clinical findings. Claude Beck, a cardiovascular surgeon, described 2 triads of clinical findings that he found associated with acute and chronic cardiac tamponade. The first of these triads consisted of hypotension, an increased venous pressure, and a quiet heart. It has come to be recognized as Beck's triad, a collection of findings most commonly produced by acute intrapericardial hemorrhage. Subsequent studies have shown that these classic findings are observed in only a minority of patients with cardiac tamponade. [2] The detection of pericardial fluid has been facilitated by the development and continued improvement of echocardiography. [3] Cardiac ultrasound is now accepted as the criterion standard imaging modality for the assessment of pericardial effusions and the dynamic findings consistent with cardiac tamponade. With echocardiography, the location of the effusion can be identified, the size can be estimated (small, medium, or large), and the hemodynamic effects can be examined by assessing for abnormal septal motion, right atrial or right ventricular inversion, and decreased respiratory variation of the diameter of the inferior vena cava.

Wilson Disease
Wilson Disease samer kareem 10,103 Views • 2 years ago

Wilson's disease is a rare inherited disorder that causes too much copper to accumulate in your liver, brain and other vital organs. Symptoms typically begin between the ages of 12 and 23. Copper plays a key role in the development of healthy nerves, bones, collagen and the skin pigment melanin. Normally, copper is absorbed from your food, and any excess is excreted through bile — a substance produced in your liver.

Liddle's Syndrome
Liddle's Syndrome samer kareem 1,863 Views • 2 years ago

Liddle syndrome is an inherited form of high blood pressure (hypertension). This condition is characterized by severe hypertension that begins unusually early in life, often in childhood, although some affected individuals are not diagnosed until adulthood. Some people with Liddle syndrome have no additional signs or symptoms, especially in childhood. Over time, however, untreated hypertension can lead to heart disease or stroke, which may be fatal.

Familial Hypocalciuric Hypercalcemia
Familial Hypocalciuric Hypercalcemia samer kareem 4,345 Views • 2 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.
