Synthol, otherwise known as site enhancement oil is used by some people (including bodybuilders) to increase the apparent size of their muscles by directly injecting the oil into their muscle tissue. Users treat it as a short cut of looking like a body builder, without the actual hard work of bodybuilding training. With repeated injections, a larger volume of synthol builds up inside the muscle, expanding its size like a balloon filling up with air. Side effects of synthol can cause nerve damage, stroke, ulcers, pulmonary embolisms, and much more. Injecting synthol is very dangerous and if that doesn’t deter potential users, there is also a problem from an aesthetic standpoint; synthol use makes ones body look deformed (just see for yourself in the pictures below).
Peristalsis, involuntary movements of the longitudinal and circular muscles, primarily in the digestive tract but occasionally in other hollow tubes of the body, that occur in progressive wavelike contractions. Peristaltic waves occur in the esophagus, stomach, and intestines.

Barrett's esophagus is a complication of chronic (long lasting) and usually severe gastrointestinal reflux disease (GERD), but occurs in only a small percentage of patients with GERD. Criteria are needed for screening patients with GERD for Barrett's esophagus. Until validated criteria are available, it seems reasonable to do screening endoscopies in GERD patients who cannot be taken off acid suppression therapy after two to three years. The diagnosis of Barrett's esophagus rests upon seeing (at endoscopy) a pink esophageal lining that extends a short distance (usually less than 2.5 inches) up the esophagus from the gastroesophageal junction and finding intestinal type cells (goblet cells) on biopsy of the lining. There is a small but definite increased risk of cancer of the esophagus (adenocarcinoma) in patients with Barrett's esophagus.

The dural venous sinuses are spaces between the endosteal and meningeal layers of the dura. They contain venous blood that originates for the most part from the brain or cranial cavity. The sinuses contain an endothelial lining that is continuous into the veins that are connected to them.
Before Dr. Benjamin Carson became the first person to successfully separate twins conjoined at the head, before he had a TV movie made about his life, before he became known for his "gifted hands" and before he became head of pediatric neurosurgery at Johns Hopkins, Ben Carson was headed down the wrong path in life.
Multiple sclerosis causes many different symptoms, including vision loss, pain, fatigue, and impaired coordination. The symptoms, severity, and duration can vary from person to person. Some people may be symptom free most of their lives, while others can have severe chronic symptoms that never go away. Physical therapy and medications that suppress the immune system can help with symptoms and slow disease progression.
Extracorporeal shock wave lithotripsy (ESWL) uses shock waves to break a kidney stone into small pieces that can more easily travel through the urinary tract camera.gif and pass from the body. See a picture of ESWL camera.gif. You lie on a water-filled cushion, and the surgeon uses X-rays or ultrasound tests to precisely locate the stone. High-energy sound waves pass through your body without injuring it and break the stone into small pieces. These small pieces move through the urinary tract and out of the body more easily than a large stone. The process takes about an hour. You may receive sedatives or local anesthesia. Your surgeon may use a stent if you have a large stone. A stent is a small, short tube of flexible plastic mesh that holds the ureter open. This helps the small stone pieces to pass without blocking the ureter.

Rectal bleeding can refer to any blood that passes from your anus, although rectal bleeding is usually assumed to refer to bleeding from your lower colon or rectum. Your rectum makes up the last few inches of your large intestine. Rectal bleeding may show up as blood in your stool, on the toilet paper or in the toilet bowl. Blood that results from rectal bleeding can range in color from bright red to dark maroon to a dark, tarry color.
