Benzodiazepines
Benzodiazepines samer kareem 3,997 Views • 2 years ago

Benzodiazepines are a class of agents that work on the central nervous system, acting selectively on gamma-aminobutyric acid-A (GABA-A) receptors in the brain. GABA is a neurotransmitter that inhibits or reduces the activity of nerve cells (neurons) within the brain. Benzodiazepines open GABA-activated chloride channels, and allow chloride ions to enter the neuron. This makes the neuron negatively charged and resistant to excitation.

What Is The Procedure For An Endoscopy?
What Is The Procedure For An Endoscopy? samer kareem 8,674 Views • 2 years ago

This animated video is an informative video that provides information regarding Upper Gastro-intestinal Endoscopy. An upper GI endoscopy procedure allows your doctor to view the mucus lining of the upper portion of your gastro-intestinal tract. This includes your oesophagus, stomach and duodenum. Upper endoscopy is used to evaluate symptoms of persistent upper abdominal pain, nausea, vomiting, bleeding, or difficulty in swallowing. The procedure is performed using an endoscope which is a long thin flexible tube a light and a tiny video camera attached to the end. The camera transmits the image to a monitor. Uncomplicated upper endoscopy takes 10-20 minutes, your doctor will gently insert the endoscope through your mouth and then slowly and carefully move it down your oesophagus until it reaches your stomach. An endoscopy for stomach may also be necessary in some cases.

Does Size Really Matter?
Does Size Really Matter? samer kareem 3,188 Views • 2 years ago

Of the many factors that affect your compatibility with a man, one of the biggest (or smallest) is in his pants. As with humour, interests or habits, the wrong fit can leave you cold. Or traumatised. In a study of 1,661 penises, Dr Debby Herbenick, author of Sex Made Easy, found an almost nine-inch difference in erection size: from 1.6 inches to 10.2. And since absolutely nothing outside the package tells you what to expect with the package, you have to test compatibility the hard way. Sometimes you hit your jackpot, sometimes it's just fine, and sometimes he's the guy on either end of that erection spectrum. These writers have been there, so here's what they learned - and how you can deal (without the gasp reflex).

Sarcoidosis Diagnosis
Sarcoidosis Diagnosis samer kareem 1,215 Views • 2 years ago

A diagnosis of sarcoidosis is established on the basis of compatible clinical and radiologic findings and histologic evidence of the presence of noncaseous epithelioid cell granulomas in one or more organs and the absence of causative organisms or particulates (16). Granulomas of known causes and local sarcoidlike reactions must be excluded. Granulomatous lesions may result from many conditions, including tuberculosis, berylliosis, leprosy, hypersensitivity pneumonitis, Crohn disease, primary biliary cirrhosis, and fungal disease. Moreover, local sarcoidlike reactions may be seen in lymph nodes that drain a neoplasm or a site of chronic inflammation (19). Such reactions also have been seen in patients who have undergone chemotherapy and radiation therapy (23). If biopsy of lymph nodes or pulmonary or pleural tissue is necessary for diagnosis, one of three techniques may be used: transbronchial biopsy, CT-guided biopsy, or surgical biopsy (24). The use of a surgical technique may be warranted when the results of biopsy with another procedure are not definitive and biopsy of mediastinal lymph nodes, lung, or both is required. This can generally be done with minimally invasive procedures, such as cervical mediastinoscopy, the Chamberlain procedure (a parasternal minithoracotomy for biopsy of the aortopulmonary window or para-aortic nodes), or video-assisted thoracoscopic surgical biopsy (25).

Heart Transplant !
Heart Transplant ! samer kareem 10,229 Views • 2 years ago

The first operation is harvesting the heart from the donor. The donor is usually an unfortunate person who has suffered irreversible brain injury, called "brain death". Very often these are patients who have had major trauma to the head, for example, in an automobile accident. The victim's organs, other than the brain, are working well with the help of medications and other "life support" that may include a respirator or other devices. A team of physicians, nurses, and technicians goes to the hospital of the donor to remove donated organs once brain death of the donor has been determined. The removed organs are transported on ice to keep them alive until they can be implanted. For the heart, this is optimally less than six hours. So, the organs are often flown by airplane or helicopter to the recipient's hospital.
