Endoscopic Dacryocystorhinostomy
Endoscopic Dacryocystorhinostomy samer kareem 7,140 Visualizzazioni • 2 anni fa

Dacryocystorhinostomy (DCR) is a procedure performed for the treatment of tearing (epiphora) due to blockage of the nasolacrimal duct. Tears originate in the lacrimal gland, located at the upper outer margin of the eye. As tears cross the eye with each blink, they are directed into small openings in the eyelids called puncta. From this point, tears travel through a pathway known as the canalicular system into the lacrimal sac. The lacrimal sac is located between the eye and the nose, and funnels tears into the nasal cavity through the nasolacrimal duct (Figure 1). As this is quite a long path for tears to travel, there can be many causes of excessive tearing. Blockage of the nasolacrimal duct is one common cause, and can be treated by creating a direct opening from the lacrimal sac into the nasal cavity in a procedure known as DCR. The evaluation and management of tearing may involve both an ophthalmologist and an otolaryngologist.

This video shows Prof Dan Reinstein, MD MA(Cantab) FRCSC DABO FRCOphth FEBO performing a ReLEx SMILE keyhole LASIK procedure using the latest surgical instrument that he helped to develop (Malosa MMSU1297 - Reinstein Lenticule Separator: http://www.malosa.com/en/reinstein-le...). This instrument enables the procedure to be performed with one instrument, through one 2mm incision, using only one sweep per plane, and taking about 30 seconds to separate and withdraw the lenticule, improving day 1 uncorrected vision over other lenticule extraction techniques that require more corneal manipulation.

How to Perform Obstetric Palpation
How to Perform Obstetric Palpation samer kareem 24,477 Visualizzazioni • 2 anni fa

The obstetric examination is distinct from other examinations in that you, the clinician, are trying to assess the health of two individuals – the mother and the fetus – simultaneously. From the initial history, you should be able to judge the health of the pregnancy, any risk factors that need to be addressed, and any concerns from the parents. The history is an opportunity for you to find out how much the parents know about pregnancy, labour and delivery and if they have any preferences to which these events are carried out. A carefully taken history will also direct your attention to specific signs during the examination. As such, it is important that you develop a concise and systematic method of taking the history and carrying out the examination so that you do not miss any important information. This article focuses primarily on the examination. Pregnancy is a sensitive issue, especially for the primigravida’s. Therefore, extra care is needed when you approach a pregnant woman. Always obtain expressed informed consent before examining her and have a chaperone accompany you throughout the examination. A walk-through of what you will be doing is a good way of reassuring the patient and allows the examination to go on smoothly. It is also important to let your patient know that if the examination is too painful, she can stop at any time she wants. Finally, before you begin, you should always wash your hands, especially at an OSCE station.

Gynecological History
Gynecological History samer kareem 4,182 Visualizzazioni • 2 anni fa

General Considerations Because a discussion of reproductive issues may be difficult for some women, it is important to obtain the history in a relaxed and private setting. The patient should be clothed, particularly if she is meeting the provider for the first time. Ordinarily, the patient should be interviewed alone. Exceptions may be made for children, adolescents, and mentally impaired women, or if the patient specifically requests the presence of a caretaker, friend, or family member. However, even in these circumstances, it is desirable for the patient to have some time to speak with the clinician privately. The manner of address should be formal using the title Mrs., Ms., Miss, or Dr. with the patient’s surname, unless the patient requests otherwise. In some settings, it may be appropriate for nursing staff to be involved with history taking. A nurse may be perceived as less threatening, and may be able to take the history in a less hurried manner.1 The provider can verify the history and focus on areas of concern. Alternatively, it may be helpful to ask the patient to complete a self-history form on paper or by computer prior to speaking with the provider. This allows the provider to devote time to addressing positive responses, and ensures that important questions are not missed. Hasley2 showed that responses to a computer-based questionnaire designed to update a patient’s gynecologic history were equivalent to those obtained during a personal interview. Several studies involving patients in non-gynecologic settings have shown that patients are more likely to provide sensitive information when responding to a computer-based questionnaire as opposed to a personal interview or even a paper questionnaire.3 In order to increase a patient’s level of comfort during the interview, questions should be asked in an open-ended and nonjudgmental way. Assumptions should not be made about aspects of the patient’s background such as sexual orientation. At the conclusion of the interview, patients should be asked whether there are concerns that they would like to discuss that were not addressed previously in the interview.

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.

Spleen Anatomy and Physiology
Spleen Anatomy and Physiology samer kareem 3,030 Visualizzazioni • 2 anni fa

The spleen is an organ in the upper far left part of the abdomen, to the left of the stomach. The spleen varies in size and shape between people, but it’s commonly fist-shaped, purple, and about 4 inches long. Because the spleen is protected by the rib cage, you can’t easily feel it unless it’s abnormally enlarged. The spleen plays multiple supporting roles in the body. It acts as a filter for blood as part of the immune system. Old red blood cells are recycled in the spleen, and platelets and white blood cells are stored there. The spleen also helps fight certain kinds of bacteria that cause pneumonia and meningitis.

Colon Polyp
Colon Polyp samer kareem 6,862 Visualizzazioni • 2 anni fa

Colon polyp facts Colon polyps are growths on the inner lining of the colon and are very common. Colon polyps are important because they may be, or may become malignant (cancerous). They also are important because based on their size, number, and microscopic anatomy (histology); they can predict which patients are more likely to develop more polyps and colon cancer. Changes in the genetic material of cells lining the colon are the cause of polyps. There are different types of colon polyps with differing tendencies to become malignant and abilities to predict the development of more polyps and cancer. It is important to recognize families with members who have familial genetic conditions causing polyps because some of these conditions are associated with a very high incidence of colon cancer, and the cancer can be prevented or discovered early.

Endometrial Polyp
Endometrial Polyp samer kareem 20,648 Visualizzazioni • 2 anni fa

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.

Spinal Injury - Jaw Thrust
Spinal Injury - Jaw Thrust samer kareem 5,630 Visualizzazioni • 2 anni fa

The jaw thrust is a method of opening the airway of a patient. The airway is very important in first aid! It consists of the structures in the back of the throat and upper neck. A patient who is unconscious is not able to maintain their own airway as it can become blocked by the tongue (see picture). Normally, first aid courses teach the head tilt – chin lift technique to open an airway. However, this airway manoeuvre involves significant movement of the patient’s neck. Therefore if there is any suspicion of a spinal (neck) injury it may cause further damage.

World's First Head Transplant: samer kareem 22,401 Visualizzazioni • 2 anni fa

A man set to become the world’s first head transplant patient has scheduled the procedure for December 2017. Valery Spiridonov, 30, was diagnosed with a genetic muscle-wasting condition called Werdnig-Hoffmann disease, and volunteered for the procedure despite the risks involved, Central European News (CEN) reported. “When I realized that I could participate in something really big and important, I had no doubt left in my mind and started to work in this direction,” Spiridonov, a Russian computer scientist, told CEN. “The only thing I feel is the sense of pleasant impatience, like I have been preparing for something important all my life and it is starting to happen.”
