Choosing not to have sex provides 100 percent protection from HIV, STIs, and pregnancy. For some, this means avoiding vaginal, anal, and oral-genital intercourse altogether. Others may choose to avoid any type of sexual or intimate contact, including hugging and kissing. Choosing not to have sex is often referred to as “abstinence.” WHAT ARE THE ADVANTAGES OF CHOOSING NOT TO HAVE SEX (ABSTINENCE)? Choosing not to have sex is free and available to all. Not having sex is extremely effective at preventing both infection and pregnancy. It is the only 100% effective method of preventing sexually transmitted infections (STIs) and unintended pregnancy. Not having sex can be practiced at any time in one's life. Not having sex may encourage people to build relationships in other ways. Not having sex may be the course of action which you feel is right for you and makes you feel good about yourself.

Breast Cancer Signs
Breast Cancer Signs samer kareem 2,211 Views • 3 years ago

WARNING SIGNS OF BREAST CANCER Due to the use of regular mammography screening, most breast cancers in the U.S. are found at an early stage, before warning signs appear. However, not all breast cancers are found through mammography. The warning signs of breast cancer are not the same for all women. The most common signs are a change in the look or feel of the breast, a change in the look or feel of the nipple and nipple discharge. If you have any of the warning signs described below, see a health care provider [21-23]. If you do not have a provider, one of the best ways to find a good one is to get a referral from a trusted family member or friend. If that’s not an option, call your health department, a clinic or a nearby hospital.

Orchitis
Orchitis samer kareem 3,441 Views • 3 years ago

Orchitis (or-KIE-tis) is an inflammation of one or both testicles. It is usually caused by a bacterial infection or by the mumps virus. Bacterial orchitis can be caused by sexually transmitted infections (STIs), particularly gonorrhea or chlamydia. Bacterial orchitis often results from epididymitis, an inflammation of the coiled tube (epididymis) at the back of the testicle that stores and carries sperm. In that case, it's called epididymo-orchitis. Orchitis causes pain and can affect fertility. Medication can treat the causes of bacterial orchitis and can ease some signs and symptoms of viral orchitis. But it may take several weeks for scrotal tenderness to disappear.

Flu  Virus
Flu Virus samer kareem 2,277 Views • 3 years ago

There are two main types of influenza (flu) virus: Types A and B. The influenza A and B viruses that routinely spread in people (human influenza viruses) are responsible for seasonal flu epidemics each year. Influenza A viruses can be broken down into sub-types depending on the genes that make up the surface proteins. Over the course of a flu season, different types (A & B) and subtypes (influenza A) of influenza circulate and cause illness.

Unusual Abscess
Unusual Abscess samer kareem 3,649 Views • 3 years ago

An abscess is a tender mass generally surrounded by a colored area from pink to deep red. Abscesses are often easy to feel by touching. The middle of an abscess is full of pus and debris. Painful and warm to touch, abscesses can show up any place on your body. The most common sites are in your armpits (axillae), areas around your anus and vagina(Bartholin gland abscess), the base of your spine (pilonidal abscess), around a tooth (dental abscess), and in your groin. Inflammation around a hair follicle can also lead to the formation of an abscess, which is called a boil (furuncle). Unlike other infections, antibiotics alone will not usually cure an abscess. In general an abscess must open and drain in order for it to improve. Sometimes draining occurs on its own, but generally it must be opened by a doctor in a procedure called incision and drainage (I&D).

Pacemakers & Implantable Defibrillators
Pacemakers & Implantable Defibrillators samer kareem 2,461 Views • 3 years ago

ICDs are useful in preventing sudden death in patients with known, sustained ventricular tachycardia or fibrillation. Studies have shown ICDs to have a role in preventing cardiac arrest in high-risk patients who haven't had, but are at risk for, life-threatening ventricular arrhythmias. View an animation of an ICD. Newer-generation ICDs may have a dual function which includes the ability to serve as a pacemaker. The pacemaker feature would stimulate the heart to beat if the heart rate is detected to be too slow. What is an Implantable Cardioverter Defibrillator (ICD)? An ICD is a battery-powered device placed under the skin that keeps track of your heart rate. Thin wires connect the ICD to your heart. If an abnormal heart rhythm is detected the device will deliver an electric shock to restore a normal heartbeat if your heart is beating chaotically and much too fast. ICDs have been very useful in preventing sudden death in patients with known, sustained ventricular tachycardia or fibrillation. Studies have shown that they may have a role in preventing cardiac arrest in high-risk patients who haven't had, but are at risk for, life-threatening ventricular arrhythmias.

The preferred route of access for temporary transvenous pacing is the internal jugular vein followed by subclavian and femoral veins. However, all the major venous access sites (internal and external jugular, subclavian, brachial, femoral) have been used and each is associated with particular problems.

Claudication
Claudication samer kareem 4,814 Views • 3 years ago

Claudication is pain caused by too little blood flow, usually during exercise. Sometimes called intermittent claudication, this condition generally affects the blood vessels in the legs, but claudication can affect the arms, too. At first, you'll probably notice the pain only when you're exercising, but as claudication worsens, the pain may affect you even when you're at rest. Although it's sometimes considered a disease, claudication is technically a symptom of a disease. Most often, claudication is a symptom of peripheral artery disease, a potentially serious but treatable circulation problem in which the vessels that supply blood flow to your legs or arms are narrowed. Fortunately, with treatment, you may be able to maintain an active lifestyle without pain.

Rotationplasty is a type of autograft wherein a portion of a limb is removed, while the remaining limb below the involved portion is rotated and reattached. This procedure is used when a portion of an extremity is injured or involved with a disease, such as cancer. Typically, the ankle joint becomes the knee joint.

Sickle Cell Disease
Sickle Cell Disease samer kareem 9,367 Views • 3 years ago

This video: Sickle cell anemia is an inherited form of anemia which is 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.

On the rhythm strip, the QRS might be somewhat taller or wider. One commonly seen type of polymorphic ventricular tachycardia is torsades de pointes. Torsades and other polymorphic VT are advanced rhythms which require additional expertise and expert consultation is advised.

Pheochromocytoma
Pheochromocytoma samer kareem 3,131 Views • 3 years ago

A pheochromocytoma (fee-o-kroe-moe-sy-TOE-muh) is a rare, usually noncancerous (benign) tumor that develops in cells in the center of an adrenal gland. You have two adrenal glands, one above each kidney. Your adrenal glands produce hormones that give instructions to virtually every organ and tissue in your body. If you have a pheochromocytoma, an adrenal gland releases hormones that cause persistent or episodic high blood pressure. If left untreated, a pheochromocytoma can result in severe or life-threatening damage to other body systems, especially the cardiovascular system. Most people with a pheochromocytoma are between the ages of 20 and 50, but the tumor can develop at any age. Surgical treatment to remove a pheochromocytoma usually returns blood pressure to normal.

To remove a smaller stone in your ureter or kidney, your doctor may pass a thin lighted tube (ureteroscope) equipped with a camera through your urethra and bladder to your ureter. Once the stone is located, special tools can snare the stone or break it into pieces that will pass in your urine.

Robotic Partial Nephrectomy
Robotic Partial Nephrectomy samer kareem 2,339 Views • 3 years ago

The robotic approach to renal surgery, particularly partial nephrectomy, has some inherent challenges, and some familiarity with the da Vinci robotic system is necessary. The surgeon must gain an understanding of the robotic arm movements and range of motion, especially in relation to the clutch and camera. The advent of robotically assisted prostatectomy in 2001 [23] paved the way for widespread accessibility to the da Vinci robotic unit and its application to renal surgery. Since that time, at least one multi-institutional survey has demonstrated superiority of the robotic approach when compared to laparoscopic for outcomes of blood loss, hospital stay and a substantially shorter warm ischemia time, while maintaining equivalence in positive margin rate, operative time and complications. [11] A transperitoneal approach is most commonly used. Prior abdominal operation is not necessarily a contraindication to this procedure, but access should be approached with regard for previous operation(s) by an experienced team.

Gestational trophoblastic disease
Gestational trophoblastic disease samer kareem 2,343 Views • 3 years ago

What is gestational trophoblastic disease? Cancer starts when cells in the body begin to grow out of control. Cells in nearly any part of the body can become cancer, and can spread to other areas of the body. To learn more about how cancers start and spread, see What Is Cancer? Gestational trophoblastic (jeh-STAY-shuh-nul troh-fuh-BLAS-tik) disease (GTD) is a group of rare tumors that involve abnormal growth of cells inside a woman's uterus. GTD does not develop from cells of the uterus like cervical cancer or endometrial (uterine lining) cancer do. Instead, these tumors start in the cells that would normally develop into the placenta during pregnancy. (The term gestational refers to pregnancy.) GTD begins in the layer of cells called the trophoblast (troh-fuh-BLAST) that normally surrounds an embryo. (Tropho- means nutrition, and -blast means bud or early developmental cell.) Early in normal development, the cells of the trophoblast form tiny, finger-like projections known as villi. The villi grow into the lining of the uterus. In time, the trophoblast layer develops into the placenta, the organ that protects and nourishes the growing fetus.

How to Remove Cholesterol From Your bod
How to Remove Cholesterol From Your bod samer kareem 21,957 Views • 3 years ago

Cholesterol is a fat-like, waxy substance that can be found in all parts of your body. It helps your body make cell membranes, many hormones, and vitamin D. The cholesterol in your blood comes from two sources: the foods you eat and your liver. But your liver makes all the cholesterol your body needs.

Hemoglobin Breakdown
Hemoglobin Breakdown samer kareem 5,863 Views • 3 years ago

Red blood cells, which form one of the major constituents of blood, are characterized by the absence of nuclei, hence they are unable to undergo cellular division or generate new erythrocytes from old ones. This eventually leads to cell disintegration, which typically occurs 4 months after the fully developed red blood cells have been in circulation within the bloodstream. During the degeneration of the red blood cells, some components of the hemoglobin are excreted from the body while other parts are conserved.
