Blood clotting, or coagulation, is an important process that prevents excessive bleeding when a blood vessel is injured. Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.
The external jugular vein receives the greater part of the blood from the exterior of the cranium and the deep parts of the face, being formed by the junction of the posterior division of the retromandibular vein with the posterior auricular vein.
A facet joint injection is a relatively simple, straightforward procedure, and is usually performed in an office based procedure suite or in an ambulatory surgical center. As with many spinal injections, facet joint injections are best performed using fluoroscopy (live X-ray) for guidance to properly target and place the needle (and to help avoid nerve injury or other injury).
Chordoid meningioma, classified as atypical meningioma according to the World Health Organisation (WHO) classification, is a rare subtype, which represents only 0.5% of all meningiomas and is associated with a high incidence of recurrence. Multiple intracranial meningiomas are rare in non-neurofibromatosis patients. We present a female patient with both of these rare types of meningioma. The patient presented with two concurrent intracranial meningiomas, with one a meningotheliomatous subtype and the other a chordoid meningioma. Given the wide array of histological differential diagnoses in chordoid meningioma, immunohistochemistry has a significant role to play in differentiating them. Recurrence in chordoid meningioma can be generally predicted based on the extent of resection, the percentage of chordoid element, and proliferation indices.

First described by Aubaniac in 1952, central venous catheterization, or central line placement, is a time-honored and tested technique of quickly accessing the major venous system. Benefits over peripheral access include greater longevity without infection, line security in situ, avoidance of phlebitis, larger lumens, multiple lumens for rapid administration of combinations of drugs, a route for nutritional support, fluid administration, and central venous pressure (CVP) monitoring. Central vein catheterization is also referred to as central line placement. Overall complication rates are as high as 15%, [1, 2, 3, 4] with mechanical complications reported in 5-19% of patients, [5, 6, 7] infectious complications in 5-26%, [1, 2, 4] and thrombotic complications in 2-26%. [1, 8] These complications are all potentially life-threatening and invariably consume significant resources to treat. Placement of a central vein catheter is a common procedure, and house staff require substantial training and supervision to become facile with this technique. A physician should have a thorough foreknowledge of the procedure and its complications before placing a central vein catheter. The supraclavicular approach was first put into clinical practice in 1965 and is an underused method for gaining central access. It offers several advantages over the infraclavicular approach to the subclavian vein. At the insertion site, the subclavian vein is closer to the skin, and the right-side approach offers a straighter path into the subclavian vein. In addition, this site is often more accessible during cardiopulmonary resuscitation (CPR) and during active surgical cases. Finally, in patients who are obese, this anatomic area is less distorted.
Capsaicin binds to pain receptors on our nerves called TRPV1. Normally, it reacts to heat by sending warning signals to the brain. Capsaicin causes TRPV1 to send those same signals. So, you react as if there's something hot in your mouth
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.
The Epley maneuver is a series of movements, normally carried out on a person by a doctor, to relieve the symptoms of BPPV. Research has found it to be an easy, safe, and effective treatment for the condition in both the long- and short-term. The Epley maneuver is sometimes called the particle repositioning maneuver or the canalith repositioning maneuver. These names are used because the maneuver involves a series of movements that help to reposition crystals in a person's ear that may cause feelings of dizziness. Repositioning the crystals helps to relieve the person's dizziness and nausea.
Wilms tumor, also known as nephroblastoma, is a cancer of the kidneys that typically occurs in children, rarely in adults. It is named after Dr. Max Wilms, the German surgeon (1867–1918) who first described it. Approximately 500 cases are diagnosed in the U.S. annually.
ACE inhibitors Email this page to a friend Print Facebook Twitter Google+ Angiotensin-converting enzyme (ACE) inhibitors are medicines. They treat heart, blood vessel, and kidney problems. How ACE inhibitors help ACE inhibitors are used to treat heart disease. These medicines make your heart work less hard by lowering your blood pressure. This keeps some kinds of heart disease from getting worse. Most people who have heart failure take these medicines. These medicines treat high blood pressure, strokes, or heart attacks. They may help lower your risk for stroke or heart attack. They are also used to treat diabetes and kidney problems. This can help keep your kidneys from getting worse. If you have these problems, ask your health care provider if you should be taking these medicines.
Endometriosis (en-doe-me-tree-O-sis) is an often painful disorder in which tissue that normally lines the inside of your uterus — the endometrium — grows outside your uterus. Endometriosis most commonly involves your ovaries, fallopian tubes and the tissue lining your pelvis. Rarely, endometrial tissue may spread beyond pelvic organs.
Uterine polyps are growths attached to the inner wall of the uterus that extend into the uterine cavity. Overgrowth of cells in the lining of the uterus (endometrium) leads to the formation of uterine polyps, also known as endometrial polyps. These polyps are usually noncancerous (benign), although some can be cancerous or can eventually turn into cancer (precancerous polyps). Uterine polyps range in size from a few millimeters — no larger than a sesame seed — to several centimeters — golf-ball-size or larger. They attach to the uterine wall by a large base or a thin stalk.
Letting children patients play the role of a dentist may be a good way to introduce them to the different types of instruments used in a dental clinic. This in turn may also reduce thier anxiety or fear of the dentist and make them more easy-going and compliant towards dental treatments. Ofcourse instruments should be clean and steril and care should be taken to not give them pointed or sharp objects.
Cushing's disease is a serious condition of an excess of the steroid hormone cortisol in the blood level caused by a pituitary tumor secreting adrenocorticotropic hormone (ACTH). ACTH is a hormone produced by the normal pituitary gland. ACTH stimulates the adrenal glands (located on top of the kidneys) to produce cortisol, commonly referred to as the stress hormone.
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.
