Sciatica Pain. samer kareem 11,327 Views • 2 years ago

Sciatica is often characterized by one or more of the following symptoms: Constant pain in only one side of the buttock or leg (rarely in both legs) Pain that is worse when sitting Leg pain that is often described as burning, tingling, or searing (versus a dull ache) Weakness, numbness, or difficulty moving the leg, foot, and/or toes A sharp pain that may make it difficult to stand up or walk Pain that radiates down the leg and possibly into the foot and toes (it rarely occurs only in the foot) Sciatica Causes and Treatments Video Watch: Sciatica Causes and Treatments Video Sciatic pain can vary from infrequent and irritating to constant and incapacitating. Symptoms are usually based on the location of the pinched nerve. While symptoms can be painful and potentially debilitating, it is rare that permanent sciatic nerve damage (tissue damage) will result, and spinal cord involvement is possible but rare.

Gastric Bypass
Gastric Bypass samer kareem 20,381 Views • 2 years ago

Gastric bypass is surgery that helps you lose weight by changing how your stomach and small intestine handle the food you eat. After the surgery, your stomach will be smaller. You will feel full with less food. The food you eat will no longer go into some parts of your stomach and small intestine that absorb food. Because of this, your body will not get all of the calories from the food you eat.

Condoms: Facts you should know
Condoms: Facts you should know Alicia Berger 4,095 Views • 2 years ago

Most of us have taken a sex education class or two. We know what condoms are supposed to be used for. Whether or not people use condoms every time they are necessary is a totally different story. You were probably taught the necessary but embarrassing lesson of how to put a condom on by the visual aids your sex education teacher provided. Of course, these tactics are a little more modern, so depending on how old you are, you may not have learned the basics of condom use until after high school. Yes, condoms are a pretty smart invention and they’re pretty safe to use. They are over 90% effective against sexually transmitted diseases (STDs), and of course, they help to reduce the risk of pregnancy by 98%. Some guys claim that they’re not comfortable to wear, which is why some companies have come up with new condoms that have a more natural fit and provide pleasure for both partners. However, with all the things we know about condoms, there’s still so much we don’t know. Here are 10 facts about condoms that are just as interesting as the condoms themselves.

wisdom teeth removal - surgery,extraction
wisdom teeth removal - surgery,extraction samer kareem 3,293 Views • 2 years ago

Simply put, there isn’t enough room for wisdom teeth because our jaws don’t grow to be big enough to have enough space for them to come in. Since there isn’t enough room for them to erupt properly, wisdom teeth tend to come in at an angle or they don’t fully emerge, which causes problems for the rest of the mouth. Third molars (the wisdom teeth) routinely damage the teeth right next door, called second molars. Dentists recommend removing wisdom teeth before they become a problem and to avoid a more complicated surgery. Read more at Ask the Dentist: https://askthedentist.com/wisdom-teeth-removal/

Rotator Cuff Injury
Rotator Cuff Injury samer kareem 1,864 Views • 2 years ago

The rotator cuff is a group of muscles and tendons that surround the shoulder joint, keeping the head of your upper arm bone firmly within the shallow socket of the shoulder. A rotator cuff injury can cause a dull ache in the shoulder, which often worsens when you try to sleep on the involved side. Rotator cuff injuries occur most often in people who repeatedly perform overhead motions in their jobs or sports. Examples include painters, carpenters, and people who play baseball or tennis. The risk of rotator cuff injury also increases with age. Many people recover from rotator cuff disease with physical therapy exercises that improve flexibility and strength of the muscles surrounding the shoulder joint. Sometimes, rotator cuff tears may occur as a result of a single injury. In those circumstances, medical care should be provided as soon as possible. Extensive rotator cuff tears may require surgical repair, transfer of alternative tendons or joint replacement.

Genetic Disorders And Diseases
Genetic Disorders And Diseases samer kareem 4,462 Views • 2 years ago

Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs. Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder. You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.

A good starting point for any scientist in any field is to recognize that there is much we do not know. We do not know, for example, why there is more matter than antimatter in the universe. We do not know very well how the evolution of the dinosaurs filtered out. And, perhaps most surprising of all is that we do not know very well how many organs the human body has or what all its functions are.

Multiple Endocrine Neoplasia (MEN 2B)
Multiple Endocrine Neoplasia (MEN 2B) samer kareem 1,726 Views • 2 years ago

Multiple endocrine neoplasia type 2 (MEN2) is a hereditary condition associated with three primary types of tumors: medullary thyroid cancer, parathyroid tumors, and pheochromocytoma. MEN2 is classified into three subtypes based on clinical features. MEN2A, which affects 60% to 90% of MEN2 families Medullary thyroid cancer: 98% to 100% with MEN2A are affected Pheochromocytoma, a typically benign (noncancerous) tumor of the adrenal glands: 50% with MEN2A affected Parathyroid adenoma (benign tumor) or hyperplasia, meaning increased size, of the parathyroid gland: 5% to 10% with MEN2A affected MEN2B, which affects 5% of MEN2 families Medullary thyroid cancer: 98% to 100% with MEN2B affected Pheochromocytoma: 50% with MEN2B affected Mucosal neuromas, which is a benign tumor of nerve tissue on the tongue, lips and throughout the gastrointestinal tract: 95% to 98% affected Digestive problems caused by disordered nerves in the gastrointestinal tract: 75% to 90% affected Muscle, joint, and spinal problems: 95% affected Typical facial features, including swollen lips and thick eyelids: 75% to 90% affected Familial medullary thyroid cancer (FMTC), which affects 5% to 35% of MEN2 families Medullary thyroid carcinoma only Sources: Gagel RF, Marx SJ. “Multiple endocrine neoplasia.” Williams Textbook of Endocrinology, Chapter 40, 11th ed., Philadelphia, 2008, and Eng C, Clayton D, et al. Grubbs EG, Gagel RF. My, How Things Have Changed in Multiple Endocrine Neoplasia Type 2A! J Clin Endocrinol Metab 100(7):2532-5, 7/2015. PMID: 26151398. What causes MEN2? MEN2 is a genetic condition. This means that the cancer risk and other features of MEN2 can be passed from generation to generation in a family. The gene associated with MEN2 is called RET. A mutation (alteration) in the RET gene gives a person an increased risk of developing medullary thyroid cancer and other tumors associated with MEN2.

How Do Your Lungs Work?
How Do Your Lungs Work? samer kareem 15,977 Views • 2 years ago

The lungs and respiratory system allow oxygen in the air to be taken into the body, while also enabling the body to get rid of carbon dioxide in the air breathed out. Respiration is the term for the exchange of oxygen from the environment for carbon dioxide from the body's cells.
