Heat stroke is the most serious form of heat injury and is considered a medical emergency. If you suspect that someone has heat stroke -- also known as sunstroke -- call 911 immediately and give first aid until paramedics arrive. Heat stroke can kill or cause damage to the brain and other internal organs. Although heat stroke mainly affects people over age 50, it also takes a toll on healthy young athletes. Heat stroke often occurs as a progression from milder heat-related illnesses such as heat cramps, heat syncope (fainting), and heat exhaustion. But it can strike even if you have no previous signs of heat injury. Heat stroke results from prolonged exposure to high temperatures -- usually in combination with dehydration -- which leads to failure of the body's temperature control system. The medical definition of heat stroke is a core body temperature greater than 105 degrees Fahrenheit, with complications involving the central nervous system that occur after exposure to high temperatures. Other common symptoms include nausea, seizures, confusion, disorientation, and sometimes loss of consciousness or coma

Vertigo is a sensation of spinning. If you have these dizzy spells, you might feel like you are spinning or that the world around you is spinning. Causes of Vertigo Vertigo is often caused by an inner ear problem. Some of the most common causes include: BPPV. These initials stand for benign paroxysmal positional vertigo. BPPV occurs when tiny calcium particles (canaliths) clump up in canals of the inner ear. The inner ear sends signals to the brain about head and body movements relative to gravity. It helps you keep your balance. BPPV can occur for no known reason and may be associated with age. Meniere's disease. This is an inner ear disorder thought to be caused by a buildup of fluid and changing pressure in the ear. It can cause episodes of vertigo along with ringing in the ears (tinnitus) and hearing loss. Vestibular neuritis or labyrinthitis. This is an inner ear problem usually related to infection (usually viral). The infection causes inflammation in the inner ear around nerves that are important for helping the body sense balance

Cystinuria is a condition characterized by the buildup of the amino acid cystine, a building block of most proteins, in the kidneys and bladder. As the kidneys filter blood to create urine, cystine is normally absorbed back into the bloodstream. People with cystinuria cannot properly reabsorb cystine into their bloodstream, so the amino acid accumulates in their urine. As urine becomes more concentrated in the kidneys, the excess cystine forms crystals. Larger crystals become stones that may lodge in the kidneys or in the bladder. Sometimes cystine crystals combine with calcium molecules in the kidneys to form large stones. These crystals and stones can create blockages in the urinary tract and reduce the ability of the kidneys to eliminate waste through urine. The stones also provide sites where bacteria may cause infections.

Vasculitis is an inflammation of your blood vessels. It causes changes in the walls of blood vessels, including thickening, weakening, narrowing and scarring. These changes restrict blood flow, resulting in organ and tissue damage. There are many types of vasculitis, and most of them are rare. Vasculitis might affect just one organ, such as your skin, or it may involve several. The condition can be short term (acute) or long lasting (chronic). Vasculitis can affect anyone, though some types are more common among certain groups. Depending on the type you have, you may improve without treatment. Or you will need medications to control the inflammation and prevent flare-ups. Vasculitis is also known as angiitis and arteritis.

Less than a decade ago, corneal transplantation took a big leap forward with the introduction of Descemet’s stripping endothelial keratoplasty (DSEK), which removes only Descemet’s membrane and the diseased endothelium and replaces them with a thin, tripartite donor graft of posterior corneal stroma, Descemet’s membrane, and healthy endothelium. Then came DSAEK, in which the donor graft is prepared with an automated microkeratome, allowing for easier donor preparation and reproducible results by surgeons and eye bank technicians.1 DSAEK has proved to have many advantages over penetrating keratoplasty (PK) and its endothelial predecessors (see “A Brief History of Endothelial Keratoplasty”). Now DSAEK is being compared with a newer technique, Descemet’s membrane endothelial keratoplasty (DMEK), which has emerged as a promising alternative—grafting only Descemet’s membrane and endothelium, allowing for a pure anatomical replacement of only what was removed and the possibility of even better vision with quicker healing.1 Although indications for these procedures are similar, each has unique benefits and drawbacks. Five cornea surgeons offer their perspectives on the procedures and their thoughts on whether it may be time to move to the newer surgery.

Diabetes, describes a group of metabolic diseases in which the person has high blood glucose (blood sugar), either because insulin production is inadequate, or because the body's cells do not respond properly to insulin, or both. Patients with high blood sugar will typically experience polyuria (frequent urination), they will become increasingly thirsty (polydipsia) and hungry (polyphagia).

BACKGROUND: Clubfoot occurs in approximately one in 1000 live births and is one of the most common congenital birth defects. Although there have been several reports of successful treatment of idiopathic clubfoot with the Ponseti method, the use of this method for the treatment of other forms of clubfoot has not been reported. The purpose of the present study was to evaluate the early results of the Ponseti method when used for the treatment of clubfoot associated with distal arthrogryposis. METHODS: Twelve consecutive infants (twenty-four feet) with clubfoot deformity associated with distal arthrogryposis were managed with the Ponseti method and were retrospectively reviewed at a minimum of two years. The severity of the foot deformity was classified according to the grading system of Diméglio et al. The number of casts required to achieve correction was compared with published data for the treatment of idiopathic clubfoot. Recurrent clubfoot deformities or complications during treatment were recorded. RESULTS: Twenty-two clubfeet in eleven patients were classified as Diméglio grade IV, and two clubfeet in one patient were classified as Diméglio grade II. Initial correction was achieved in all clubfeet with a mean of 6.9 +/- 2.1 casts (95% confidence interval, 5.6 to 8.3 casts), which was significantly greater than the mean of 4.5 +/- 1.2 casts (95% confidence interval, 4.3 to 4.7 casts) needed in a cohort of 219 idiopathic clubfeet that were treated during the same time period by the senior author with use of the Ponseti method (p = 0.002). Six feet in three patients had a relapse after initial successful treatment. All relapses were related to noncompliance with prescribed brace wear. Four relapsed clubfeet in two patients were successfully treated with repeat casting and/or tenotomy; the remaining two relapsed clubfeet in one patient were treated with extensive soft-tissue-release operations.

Pleurisy is a condition in which the pleura — a membrane consisting of a layer of tissue that lines the inner side of the chest cavity and a layer of tissue that surrounds the lungs — becomes inflamed. Also called pleuritis, pleurisy causes sharp chest pain (pleuritic pain) that worsens during breathing. A variety of underlying conditions can cause pleurisy. Treatment of pleurisy involves pain control and treating the underlying condition.

The kidneys are a pair of organs located in the back of the abdomen. Each kidney is about 4 or 5 inches long -- about the size of a fist. The kidneys' function are to filter the blood. All the blood in our bodies passes through the kidneys several times a day. The kidneys remove wastes, control the body's fluid balance, and regulate the balance of electrolytes. As the kidneys filter blood, they create urine, which collects in the kidneys' pelvis -- funnel-shaped structures that drain down tubes called ureters to the bladder. Each kidney contains around a million units called nephrons, each of which is a microscopic filter for blood. It's possible to lose as much as 90% of kidney function without experiencing any symptoms or problems.

When food is taken, it is broken down into smaller components. Sugars and carbohydrates are thus broken down into glucose for the body to utilize them as an energy source. The liver is also able to manufacture glucose. In normal persons the hormone insulin, which is made by the beta cells of the pancreas, regulates how much glucose is in the blood. When there is excess of glucose in blood, insulin stimulates cells to absorb enough glucose from the blood for the energy that they need. Insulin also stimulates the liver to absorb and store any excess glucose that is in the blood. Insulin release is triggered after a meal when there is a rise in blood glucose. When blood glucose levels fall, during exercise for example, insulin levels fall too. High insulin will promote glucose uptake, glycolysis (break down of glucose), and glycogenesis (formation of storage form of glucose called glycogen), as well as uptake and synthesis of amino acids, proteins, and fat. Low insulin will promote gluconeogenesis (breakdown of various substrates to release glucose), glycogenolysis (breakdown of glycogen to release gluose), lipolysis (breakdown of lipids to release glucose), and proteolysis (breakdown of proteins to release glucose). Insulin acts via insulin receptors.

A subdural hematoma is a collection of blood outside the brain. Subdural hematomas are usually caused by severe head injuries. The bleeding and increased pressure on the brain from a subdural hematoma can be life-threatening.

- Group A streptococcal pharyngitis Classic physical examination findings include tonsillar exudates, tender anterior cervical lymphadenopathy, and palatal petechiae. Diagnosis should be confirmed with throat culture (preferred) or rapid antigen testing prior to initiation of antibiotics.

There's no single best approach to uterine fibroid treatment — many treatment options exist. If you have symptoms, talk with your doctor about options for symptom relief. Watchful waiting Many women with uterine fibroids experience no signs or symptoms, or only mildly annoying signs and symptoms that they can live with. If that's the case for you, watchful waiting could be the best option. Fibroids aren't cancerous. They rarely interfere with pregnancy. They usually grow slowly — or not at all — and tend to shrink after menopause, when levels of reproductive hormones drop. Medications Medications for uterine fibroids target hormones that regulate your menstrual cycle, treating symptoms such as heavy menstrual bleeding and pelvic pressure. They don't eliminate fibroids, but may shrink them. Medications include: Gonadotropin-releasing hormone (Gn-RH) agonists. Medications called Gn-RH agonists (Lupron, Synarel, others) treat fibroids by blocking the production of estrogen and progesterone, putting you into a temporary postmenopausal state. As a result, menstruation stops, fibroids shrink and anemia often improves. Your doctor may prescribe a Gn-RH agonist to shrink the size of your fibroids before a planned surgery. Many women have significant hot flashes while using Gn-RH agonists. Gn-RH agonists typically are used for no more than three to six months because symptoms return when the medication is stopped and long-term use can cause loss of bone. Progestin-releasing intrauterine device (IUD). A progestin-releasing IUD can relieve heavy bleeding caused by fibroids. A progestin-releasing IUD provides symptom relief only and doesn't shrink fibroids or make them disappear. It also prevents pregnancy. Tranexamic acid (Lysteda). This nonhormonal medication is taken to ease heavy menstrual periods. It's taken only on heavy bleeding days. Other medications. Your doctor might recommend other medications. For example, oral contraceptives or progestins can help control menstrual bleeding, but they don't reduce fibroid size. Nonsteroidal anti-inflammatory drugs (NSAIDs), which are not hormonal medications, may be effective in relieving pain related to fibroids, but they don't reduce bleeding caused by fibroids. Your doctor may also suggest that you take vitamins and iron if you have heavy menstrual bleeding and anemia

Tooth loss can make you look older. When you lose a tooth and don’t replace it with a dental implant, you risk the chance of jawbone loss. Normally, your tooth root stimulates the continued growth and health of your jawbone. Dental implants mirror your natural tooth root and keep your jawbone healthy.

Nonalcoholic fatty liver disease is an umbrella term for a range of liver conditions affecting people who drink little to no alcohol. As the name implies, the main characteristic of nonalcoholic fatty liver disease is too much fat stored in liver cells. Nonalcoholic steatohepatitis, a potentially serious form of the disease, is marked by liver inflammation, which may progress to scarring and irreversible damage. This damage is similar to the damage caused by heavy alcohol use. At its most severe, nonalcoholic steatohepatitis can progress to cirrhosis and liver failure Nonalcoholic fatty liver disease is increasingly common around the world, especially in Western nations. In the United States, it is the most common form of chronic liver disease, affecting an estimated 80 to 100 million people. Nonalcoholic fatty liver disease occurs in every age group but especially in people in their 40s and 50s who are at high risk of heart disease because of such risk factors as obesity and type 2 diabetes. The condition is also closely linked to metabolic syndrome, which is a cluster of abnormalities including increased abdominal fat, poor ability to use the hormone insulin, high blood pressure and high blood levels of triglycerides, a type of fat.

The brain is the most complex organ in our body. It controls everything we do, from simple things such as breathing, to complex things such as co-ordinating our movements. The brain stores our memories, allows us to think and speak, and controls how we behave

Antiphospholipid (AN-te-fos-fo-LIP-id) syndrome occurs when your immune system attacks some of the normal proteins in your blood. It can cause blood clots in your arteries or veins. And it can cause pregnancy complications, such as miscarriage and stillbirth. Blood clots in your leg veins cause a condition known as deep vein thrombosis (DVT). Damage from blood clots in your organs, such as your kidneys, lungs or brain, depends on the extent and location of the clot. For instance, a clot in your brain can cause a stroke. There's no cure for antiphospholipid syndrome, but medications can reduce your risk of blood clots.
