A seizure occurs when there’s abnormal electrical activity in the brain. Seizures may go virtually unnoticed. Or, in severe cases, they may produce a change or loss of consciousness and involuntary muscle spasms called convulsions. Seizures usually come on suddenly and vary in duration and severity. A seizure may be a one-time event, or you may have seizures repeatedly. Recurrent seizures are called epilepsy, or a seizure disorder. Less than one in 10 people who has a seizure develops epilepsy. Experts classify seizures into two general categories and many subtypes based on the pattern of the attack. Generalized seizures involve both sides of the brain from the start of the attack. Common subtypes include tonic-clonic (grand mal) and absence seizures (petit mal). Febrile and infantile spasms are two types of generalized seizures that occur almost exclusively in young children. Partial (or focal) seizures are the second major seizure type. These begin in a specific area of the brain and may be contained there. Or they may spread to the entire brain. With simple partial seizures, the person remains conscious. Complex partial seizures involve impaired consciousness. What Causes Seizures? Often the cause of a seizure is unknown. Many conditions can provoke seizures, including: Stroke Brain tumors Head injuries Electrolyte imbalance Very low blood sugar Repetitive sounds or flashing lights, such as in video games Medications, such as antipsychotics and some asthma drugs Withdrawal from medications, such as Xanax, narcotics, or alcohol Use of drugs such as cocaine and heroin Cancer Brain infections, such as meningitis
Electroconvulsive therapy (ECT) is a procedure, done under general anesthesia, in which small electric currents are passed through the brain, intentionally triggering a brief seizure. ECT seems to cause changes in brain chemistry that can quickly reverse symptoms of certain mental illnesses. It often works when other treatments are unsuccessful. Much of the stigma attached to ECT is based on early treatments in which high doses of electricity were administered without anesthesia, leading to memory loss, fractured bones and other serious side effects. ECT is much safer today. Although ECT still causes some side effects, it now uses electric currents given in a controlled setting to achieve the most benefit with the fewest possible risks.
Iron deficiency anemia is a common type of anemia — a condition in which blood lacks adequate healthy red blood cells. Red blood cells carry oxygen to the body's tissues. As the name implies, iron deficiency anemia is due to insufficient iron. Without enough iron, your body can't produce enough of a substance in red blood cells that enables them to carry oxygen (hemoglobin). As a result, iron deficiency anemia may leave you tired and short of breath. You can usually correct iron deficiency anemia with iron supplementation. Sometimes additional tests or treatments for iron deficiency anemia are necessary, especially if your doctor suspects that you're bleeding internally.
Bell's palsy is a form of temporary facial paralysis resulting from damage or trauma to the facial nerves. The facial nerve-also called the 7th cranial nerve-travels through a narrow, bony canal (called the Fallopian canal) in the skull, beneath the ear, to the muscles on each side of the face. For most of its journey, the nerve is encased in this bony shell. Each facial nerve directs the muscles on one side of the face, including those that control eye blinking and closing, and facial expressions such as smiling and frowning. Additionally, the facial nerve carries nerve impulses to the lacrimal or tear glands, the saliva glands, and the muscles of a small bone in the middle of the ear called the stapes. The facial nerve also transmits taste sensations from the tongue. When Bell's palsy occurs, the function of the facial nerve is disrupted, causing an interruption in the messages the brain sends to the facial muscles. This interruption results in facial weakness or paralysis. Bell's palsy is named for Sir Charles Bell, a 19th century Scottish surgeon who described the facial nerve and its connection to the condition. The disorder, which is not related to stroke, is the most common cause of facial paralysis. Generally, Bell's palsy affects only one of the paired facial nerves and one side of the face, however, in rare cases, it can affect both sides.
Hypoparathyroidism is an uncommon condition in which your body secretes abnormally low levels of parathyroid hormone (PTH). PTH plays a key role in regulating and maintaining a balance of your body's levels of two minerals — calcium and phosphorus. The low production of PTH in hypoparathyroidism leads to abnormally low ionized calcium levels in your blood and bones and to an increase of serum phosphorus. Treatment for hypoparathyroidism consists of taking supplements to normalize your calcium and phosphorus levels. Depending on the cause of your hypoparathyroidism, you'll likely need to take supplements for life.
Lead poisoning occurs when lead builds up in the body, often over a period of months or years. Even small amounts of lead can cause serious health problems. Children under the age of 6 are especially vulnerable to lead poisoning, which can severely affect mental and physical development. At very high levels, lead poisoning can be fatal. Lead-based paint and lead-contaminated dust in older buildings are the most common sources of lead poisoning in children. Other sources include contaminated air, water and soil. Adults who work with batteries, do home renovations or work in auto repair shops also may be exposed to lead. While treatment is available for lead poisoning, taking some simple precautions can help protect yourself and your family.
Initial symptoms may include: Pain or discomfort in the upper tummy (abdomen), especially after eating. Indigestion. (Note: most people who have indigestion do not have stomach cancer.) Feeling sick, and being off food. ... Weight loss and/or loss of appetite. You may pass blood out with your stools (faeces).
Too much cholesterol in the blood can lead to cardiovascular disease. Heart disease is the No. 1 cause of death in the United States. Over 2,100 Americans die of cardiovascular disease each day, an average of one death every 40 seconds. The good news is, you can lower your cholesterol and reduce your risk of heart disease and stroke. Working with your doctor is key. It takes a team to develop and maintain a successful health program. You and your healthcare professionals each play an important role in maintaining and improving your heart health. Work with your doctor to determine your risk and the best approach to manage it. In all cases, lifestyle changes are important to reduce your risk for heart attack and stroke. In some cases, cholesterol-lowering statin medicines may also provide benefit. Learn how to make diet and lifestyle changes easy and lasting. Also make sure you understand instructions for taking medication because it won't work if you don't take it as directed. Lifestyle Changes Your diet, weight, physical activity and exposure to tobacco smoke all affect your cholesterol level. Know Your Fats Knowing which fats raise LDL cholesterol and which ones don't is the first step in lowering your risk of heart disease.
Through the hormones it produces, the thyroid gland influences almost all of the metabolic processes in your body. Thyroid disorders can range from a small, harmless goiter (enlarged gland) that needs no treatment to life-threatening cancer. The most common thyroid problems involve abnormal production of thyroid hormones. Too much thyroid hormone results in a condition known as hyperthyroidism. Insufficient hormone production leads to hypothyroidism. Although the effects can be unpleasant or uncomfortable, most thyroid problems can be managed well if properly diagnosed and treated.
Interventional Nephrology is a new and emerging subspecialty of Nephrology that mainly deals with ultrasonography of kidneys and ultrasound-guided renal biopsy, insertion of peritoneal dialysis catheters, tunneled dialysis catheters as a vascular access for patients undergoing hemodialysis as well as percutaneous ...
Constrictive pericarditis is the result of scarring and consequent loss of the normal elasticity of the pericardial sac. This leads to impairment of ventricular filling in mid and late diastole. As a result, the majority of ventricular filling occurs rapidly in early diastole and the ventricular volume does not increase after the end of the early filling period. Restrictive cardiomyopathy is characterized by a nondilated rigid ventricle, resulting in severe diastolic dysfunction and restrictive filling that produces hemodynamic changes similar to those in constrictive pericarditis. Constrictive pericarditis and restrictive cardiomyopathy both lead to diastolic heart failure with normal (or near normal) systolic function, and characteristically abnormal ventricular filling that results in similar clinical and hemodynamic features. However, because of their markedly different treatments, differentiating between the two conditions is critical. In some patients, the correct diagnosis may be readily suggested from the history or routine diagnostic testing. In others, however, this differentiation cannot be diagnosed before biopsy or even surgical exploration.
Invasive intracranial pressure monitoring. The most common surgically placed monitors for ICP measurement are intraventricular catheters (external ventricular drain [EVD] or a ventriculostomy drain) and fiberoptic ICP monitors implanted into the parenchyma of the brain.

Drink less alcohol. ... Eat more vegetables, protein and the right fats. ... Drink raw vegetable juices. ... Take a good liver tonic.
A simple continuous stitch can be a useful technique for skin closure when speed is important, e.g. closing a scalp laceration on a screaming child. The simple running, or continuous suture, is begun in the same way as a simple interrupted suture.
Repair of post-infarction ventricular septal defect (VSD) remains a challenging procedure with a high risk of VSD recurrence. In order to reduce this risk, a double patch and glue technique was introduced in the department in 1986. This surgical technique is hereunder presented. Since 1971, ninety-three patients have been operated on early (≪15 days) after the occurrence of a post-infarction VSD. This retrospective study allows to compare the results of this double patch and glue technique to those obtained with the conventional one, in terms of hospital death and VSD recurrence. The double patch and glue technique avoids recurrence of VSD and plays a part in reducing hospital mortality.
What does the placenta do? The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it. In most pregnancies, the placenta attaches at the top or side of the uterus.
The majority of epileptic seizures are controlled by medication, particularly anticonvulsant drugs. The type of treatment prescribed will depend on several factors, including the frequency and severity of the seizures and the person's age, overall health, and medical history. An accurate diagnosis of the type of epilepsy is also critical to choosing the best treatment. Drug Therapy Many drugs are available to treat epilepsy. Although generic drugs are safely used for most medications, anticonvulsants are one category where doctors proceed with caution. Most doctors prefer to use brand-name anticonvulsants, but realize that many insurance companies will not cover the cost. As a result, it is acceptable to start taking a generic anticonvulsant medication, but if the desired control is not achieved, the patient should be switched to the brand-name drug.
What could cause a blockage in the stomach? Mechanical causes of intestinal obstruction may include: Adhesions or scar tissue that forms after surgery. Foreign bodies (objects that are swallowed and block the intestines) Gallstones (rare) Hernias. Impacted stool. Intussusception (telescoping of one segment of bowel into another) Tumors blocking the intestines. Less common radiologic signs are seen in specific circumstances. Most closed-loop obstructions (75%) are caused by adhesions. A closed-loop obstruction occurs when a loop of bowel is not decompressed by the caudal passage of gas and fluid.
