Carotid Artery Disease
Carotid Artery Disease samer kareem 1,613 Views • 2 years ago

Carotid artery stenosis can be caused by cholesterol build-up in the blood vessels (atherosclerosis). Blood clots can form in this area and travel up to the brain. This condition may be present for a long time before symptoms appear. When symptoms do occur, stroke or brief stroke-like attacks are common. If this condition is discovered as a result of a stroke or stroke-like attack, cholesterol lowering medications and blood thinners may be used to improve blood flow to the brain. If the degree of narrowing is severe, surgery may be needed to open the blood vessel.

During the examination, the doctor gently puts a lubricated, gloved finger of one hand into the rectum. He or she may use the other hand to press on the lower belly or pelvic area. A digital rectal exam is done for men as part of a complete physical examination to check the prostate gland .

Spleen Pain
Spleen Pain samer kareem 8,268 Views • 2 years ago

What is the spleen and what causes an enlarged spleen (splenomegaly)? The spleen sits under your rib cage in the upper left part of your abdomen toward your back. It is an organ that is part of the lymph system and works as a drainage network that defends your body against infection. White blood cells produced in the spleen engulf bacteria, dead tissue, and foreign matter, removing them from the blood as blood passes through it. The spleen also maintains healthy red and white blood cells and platelets; platelets help your blood clot. The spleen filters blood, removing abnormal blood cells from the bloodstream. A spleen is normally about the size of your fist. A doctor usually can't feel it during an exam. But diseases can cause it to swell and become many times its normal size. Because the spleen is involved in many functions, many conditions may affect it.

Real Colonoscopy

Permanent pacemaker insertion is considered a minimally invasive procedure. Transvenous access to the heart chambers under local anesthesia is the favored technique, most commonly via the subclavian vein, the cephalic vein, or (rarely) the internal jugular vein or the femoral vein.

Urinary Tract Infection Treatment
Urinary Tract Infection Treatment samer kareem 2,881 Views • 2 years ago

Urinary tract infections (UTIs) are infections of the urethra, bladder, ureters, or the kidneys, which comprise the urinary tract. E. coli bacteria cause the majority of UTIs, but many other bacteria, fungi, and parasites may also cause UTIs. Females have a higher risk for UTIs than most males, probably because of their anatomy; other risk factors for UTIs include any condition that may impede urine flow (e.g., enlarged prostate, kidney stones, congenital urinary tract abnormalities, and inflammation). Patients with catheters or those who undergo urinary surgery and men with enlarged prostates are at higher risk for UTIs.

Since the first replant more than 50 years ago, thousands of severed body parts have been reattached, preserving the quality of life for thousands of patients through improved function and appearance that the void remaining after amputation cannot provide. Ronald Malt performed the first replantation on May 23, 1962 at Massachusetts General Hospital on a 12-year-old boy who had his right arm amputated in a train accident. [1, 2] This amputation occurred at the level of the humeral neck.

How osteoporosis develops
How osteoporosis develops samer kareem 13,076 Views • 2 years ago

Osteoporosis is a disease in which bones become brittle and fragile due to low bone mass and bone tissue loss. It's the most common type of bone disease, according to the National Institutes of Health (NIH), and increases your risk of fractures, particularly of the hips, spine, and wrists. Prevalence In the United States, nearly 54 million people ages 50 and older were living with osteoporosis or osteopenia (low bone mass ) in 2010, according to a 2014 article in the Journal of Bone and Mineral Research. More specifically, 10.2 million adults had osteoporosis, and 43.4 million adults had osteopenia, which puts a person at high risk for osteoporosis.

Pulmonary Circulation
Pulmonary Circulation samer kareem 8,638 Views • 2 years ago

Pulmonary circulation is the portion of the cardiovascular system which carries deoxygenated blood away from the heart, to the lungs, and returns oxygenated (oxygen-rich) blood back to the heart. The function of pulmonary circulation is to exchange carbon dioxide for oxygen in the blood. It is the passage of blood from the heart to the capillaries of the lungs, where the gases are exchanged, and back to the heart to be pumped around the body.

Heart
Heart samer kareem 13,207 Views • 2 years ago

The heart is the body's engine room, responsible for pumping life-sustaining blood via a 60,000-mile-long (97,000-kilometer-long) network of vessels. The organ works ceaselessly, beating 100,000 times a day, 40 million times a year—in total clocking up three billion heartbeats over an average lifetime. It keeps the body freshly supplied with oxygen and nutrients, while clearing away harmful waste matter.

A new report analyzing FDA-approved monoclonal antibodies (mAbs) produced by a select group of leading biotechnology companies shows that clinical development times – specifically the duration of Phase II and Phase III trials – are lengthening, while FDA review times have remained constant. The average time from investigational new drug (IND) filing to market was 6.7 years for 11 mABs approved between 1994 and 2003 but shot up to 8.3 years for 12 mAbs approved between 2004 and March 9, 2011, according to Deloitte Recap LLC’s analysis, Therapeutic Monoclonal Antibodies – Insights, Strategies and Data.

Nasal Polyps
Nasal Polyps samer kareem 2,137 Views • 2 years ago

Nasal polyps are soft, painless, noncancerous growths on the lining of your nasal passages or sinuses. They hang down like teardrops or grapes. They result from chronic inflammation due to asthma, recurring infection, allergies, drug sensitivity or certain immune disorders. Nasal polyps are polypoidal masses arising mainly from the mucous membranes of the nose and paranasal sinuses. They are overgrowths of the mucosa that frequently accompany allergic rhinitis, and are freely movable and nontender.

Gynecological History
Gynecological History samer kareem 4,189 Views • 2 years ago

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.

How to Perform Obstetric Palpation
How to Perform Obstetric Palpation samer kareem 24,483 Views • 2 years ago

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.

Renal agenesis is a condition in which a newborn is missing one or both kidneys. Unilateral renal agenesis (URA) is the absence of one kidney. Bilateral renal agenesis (BRA) is the absence of both kidneys. Both types of renal agenesis occur in fewer than 1 percent of births annually, according to the March of Dimes. Fewer than 1 in every 1,000 newborns has URA. BRA is much rarer, occurring in about 1 in every 3,000 births.
