Tonsillectomy (ton-sih-LEK-tuh-me) is the surgical removal of the tonsils, two oval-shaped pads of tissue at the back of the throat — one tonsil on each side. A tonsillectomy was once a common procedure to treat infection and inflammation of the tonsils (tonsillitis). Today, a tonsillectomy is usually performed for sleep-disordered breathing but may still be a treatment when tonsillitis occurs frequently or doesn't respond to other treatments. A tonsillectomy may also be necessary to treat breathing and other problems related to enlarged tonsils and to treat rare diseases of the tonsils.
Internal hemorrhoids and loose rectal mucosa may block the exposure during the purse string suturing in stapled hemorrhooidopexy, and this may cause some complications. To retract the prolapsing rectal mucosa we modified the purse string anoscope of the PPH01 kit (Ethicon-Endosurgery, Cincinnati, O...H, USA) and produced a special anoscope. The open part of the purse string suture anoscope is covered by transparent acrylic (Orthoacryl�, Dentaurum, Pforzheim, Germany). The covering material had complete cylindrical outer and inner surfaces and was thin enough to let the anoscope easily rotate in the anal dilator and to let the 26 mm curved, round bodied needle of the 2/0 polypropilene suture move in the anoscope. A window, 3 cm long and 3-4 mm wide, was opened at the angled part of the anoscope 2 cm to the tip of the anoscope. This special anoscope was used for the purse string suture during stapled hemorrhoidopexy procedure in five patients. No postoperative complications, early or late, were encountered, and we propose that stapled hemorrhoidopexy procedure can be applied more easily by using this special anoscope.
Uterine fibroids are the most common benign tumors and can affect one in three in Canada. While most fibroids are asymptomatic, they can cause heavy and painful periods, urinary frequency and urgency and pelvic discomfort and pain. A new treatment is available that doesn’t involve invasive surgery. With Fibristal, you can treat fibroids, relieve symptoms and finally live your life the way you want to!
Tension pneumothorax develops when a lung or chest wall injury is such that it allows air into the pleural space but not out of it (a one-way valve). As a result, air accumulates and compresses the lung, eventually shifting the mediastinum, compressing the contralateral lung, and increasing intrathoracic pressure enough to decrease venous return to the heart, causing shock. These effects can develop rapidly, particularly in patients undergoing positive pressure ventilation.
This video is designed for my introductory A&P course to study the endocrine system. This tutorial will take you through the various endocrine organs, hormones produced, and effects at each tissue. Prolactin is one of the 5 hormones we are studying of the anterior pituitary. SHOW MORE
Your body has nerves that connect your brain to the rest of your organs and muscles, just like telephone wires connect homes all around the world. When you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.” Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision.
Cholelithiasis involves the presence of gallstones (see the image below), which are concretions that form in the biliary tract, usually in the gallbladder. Choledocholithiasis refers to the presence of 1 or more gallstones in the common bile duct (CBD).
The menstrual cycle is the regular natural change that occurs in the female reproductive system that makes pregnancy possible. The cycle is required for the production of oocytes, and for the preparation of the uterus for pregnancy.
What combines research opportunities, intellectual challenge, and international collaboration in the study of a disease which affects many organs of the body and all sectors of society? And demands that specialists from many different backgrounds work together to crack sometimes intractable problems? It is, of course, oncology. As a career choice, it's demanding; it takes passion coupled with a willingness to put in the hours and to learn how to discuss death honestly and sensitively. But for the right person, it can be immensely rewarding.
A chronic cough is a cough that lasts eight weeks or longer in adults, or four weeks in children. A chronic cough is more than just an annoyance. A chronic cough can interrupt your sleep and leave you feeling exhausted. Severe cases of chronic cough can cause vomiting, lightheadedness and even rib fractures. While it can sometimes be difficult to pinpoint the problem that's triggering a chronic cough, the most common causes are tobacco use, postnasal drip, asthma and acid reflux. Fortunately, chronic cough typically disappears once the underlying problem is treated.
Watch Spinal Stenosis Videos Spinal stenosis occurs when the spinal cord in the neck (cervical spine) or the spinal nerve roots in the lower back (lumbar spine) are compressed. Symptoms of lumbar stenosis often include leg pain (sciatica) and leg tingling, weakness, or numbness. Arm pain is a typical symptom of cervical spinal stenosis. For cervical spinal stenosis with myelopathy, difficulty with coordination often occurs. Stenosis treatment may include non-surgical options (exercise, anti-inflammatory medication, epidural injections, and activity modification) or back surgery.
