Central vestibular nystagmus results from stimulation, injury, disease of the central vestibular pathways of the brainstem or the cerebellum, or lesion of the vestibular nuclei. It is typically a jerk nystagmus, which can be purely horizontal, vertical or torsional.
Ellie was born with a rare condition which stopped her jawbones from growing properly. At first, her parents didn't realize there was a problem, apart from the fact that her teeth were not aligned. But when she went to have braces fitted to straighten her teeth when she was 14, orthodontist Joy Hickman realized her jaw had not grown since she was eight. Over the next six years Hickman worked with a maxillofacial surgeon to transform Ellie's looks. Ellie, who is now 20, said the surgery was painful but paid almost immediate dividends. "About six months after it was my year 11 prom and it looked good." Ellie told the Daily Post the change in her appearance has been matched by an increase in confidence.
Coronary artery bypass grafting (CABG) is a type of surgery that improves blood flow to the heart. Surgeons use CABG to treat people who have severe coronary heart disease (CHD). CHD is a disease in which a waxy substance called plaque (plak) builds up inside the coronary arteries.
The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells. The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.
There are several reasons that your doctor may recommend that you have your spleen removed. These include having: a spleen that’s damaged from injury an enlarged spleen or ruptured spleen, which can occur from trauma certain rare blood disorders cancer or large cysts of the spleen infection
Femoral Embolectomy. Back. All emboli of the lower extremity, including a proximal saddle embolus at the aortic bifurcation, can be removed through the common femoral artery using Fogarty catheters. By passing these through the embolus, and by inflating the small balloon, the clot can be withdrawn and the flow restored
Sickle cell anemia is an inherited form of anemia — a condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body. Normally, your red blood cells are flexible and round, moving easily through your blood vessels. In sickle cell anemia, the red blood cells become rigid and sticky and are shaped like sickles or crescent moons. These irregularly shaped cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body. There's no cure for most people with sickle cell anemia. However, treatments can relieve pain and help prevent further problems associated with sickle cell anemia.
Priapism is a prolonged erection of the penis. The persistent erection continues hours beyond or isn't caused by sexual stimulation. Priapism is usually painful. Although priapism is an uncommon condition overall, it occurs commonly in certain groups, such as people who have sickle cell anemia. Prompt treatment for priapism is usually needed to prevent tissue damage that could result in the inability to get or maintain an erection (erectile dysfunction). Priapism is most common in men in their 30s.
Stomach cancer usually begins in the mucus-producing cells that line the stomach. This type of cancer is called adenocarcinoma. For the past several decades, rates of cancer in the main part of the stomach (stomach body) have been falling worldwide. During the same period, cancer in the area where the top part of the stomach (cardia) meets the lower end of the swallowing tube (esophagus) has become much more common. This area of the stomach is called the gastroesophageal junction.
Diabetes is a growing global health concern, as is obesity. Diabetes and obesity are intrinsically linked: obesity increases the risk of diabetes and also contributes to disease progression and cardiovascular disease. Although the benefits of weight loss in the prevention of diabetes and as a critical component of managing the condition are well established, weight reduction remains challenging for individuals with type 2 diabetes due to a host of metabolic and psychological factors. For many patients, lifestyle intervention is not enough to achieve weight loss, and alternative options, such as pharmacotherapy, need to be considered. However, many traditional glucose-lowering medications may lead to weight gain. This article focuses on the potential of currently available pharmacological strategies and on emerging approaches in development to support the glycemic and weight-loss goals of individuals with type 2 diabetes. Two pharmacotherapy types are considered: those developed primarily for blood glucose control that have a favorable effect on body weight and those developed primarily to induce weight loss that have a favorable effect on blood glucose control. Finally, the potential of combination therapies for the management of obese patients with type 2 diabetes is discussed.
Lipomas are slow-growing soft tissue tumours that rarely reach a size larger than 2 cm. Lesions larger than 5 cm, so-called giant lipomas, can occur anywhere in the body but are seldom found in the upper extremities. The authors present their experiences with eight patients having giant lipomas of the upper extremity. In addition, a review of the literature, and a discussion of the appropriate evaluation and management are included.
Papillary fibroelastoma is the third most common primary tumor of the heart and is most likely to involve the cardiac valves. Like myxomas, they arise from the endocardium in most patients and since these tumors are often incidental findings at echocardiography or autopsy, the true incidence is difficult to estimate. Most patients are older than 60 years, which also contrasts with myxomas. Papillary fibroelastomas can embolize, leading to severe neurological complications and therefore, surgical removal is advised, although there is controversy regarding small incidental lesions and the need for surgery.
