A small spontaneous pneumothorax may resolve without treatment; a pneumothorax arising as a result of lung disease or injury requires immediate treatment. Treatment may include insertion of a chest tube or aspiration of the free air in the chest cavity.Feb 19, 2016

Ankylosing Spondylitis
Ankylosing Spondylitis samer kareem 2,537 Views • 2 years ago

Ankylosing spondylitis is an inflammatory disease that, over time, can cause some of the vertebrae in your spine to fuse. This fusing makes the spine less flexible and can result in a hunched-forward posture. If ribs are affected, it can be difficult to breathe deeply. Ankylosing spondylitis affects men more often than women. Signs and symptoms typically begin in early adulthood. Inflammation also can occur in other parts of your body — most commonly, your eyes. There is no cure for ankylosing spondylitis, but treatments can lessen your symptoms and possibly slow progression of the disease.

Coronary arteries
Coronary arteries samer kareem 14,219 Views • 2 years ago

The heart receives its own supply of blood from the coronary arteries. Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood.

Subcuticular Suture
Subcuticular Suture samer kareem 18,762 Views • 2 years ago

The two biggest considerations when choosing a suture are the location and tension of the wound. Other important considerations are tensile strength, knot strength, handling, and tissue reactivity. Sutures are divided into two major groups: Absorbable – lose the majority of their tensile strength in less than 60 days. They are generally used for buried sutures and do not require removal. Non-absorbable – maintain the majority of their tensile strength for more than 60 days. They are generally used for skin surface sutures and do require removal postoperatively. Suture needles also come in a variety of shapes and sizes. Curved needles are almost exclusively used in dermatological surgery. Cutting needles move through the tissue more easily and may have their primary cutting edge on the inside of the curve (conventional cutting) or outside of the curve (reverse cutting). The benefit of reverse cutting is that the tapered puncture left by the suture is directed away from the wound edge and therefore tissue tearing is less common. Non-cutting round needles cause even less tissue tearing and may be especially useful in delicate areas and fascia.

Patent Ductus Arteriosus Ligation

This video: Patent ductus arteriosus (PDA) is a persistent opening between two major blood vessels leading from the heart. The opening, called the ductus arteriosus, is a normal part of a baby's circulatory system before birth that usually closes shortly after birth. If it remains open, however, it's called a patent ductus arteriosus. A small patent ductus arteriosus often doesn't cause problems and might never need treatment. However, a large patent ductus arteriosus left untreated can allow poorly oxygenated blood to flow in the wrong direction, weakening the heart muscle and causing heart failure and other complications. Treatment options for a patent ductus arteriosus include monitoring, medications and closure by cardiac catheterization or surgery.

Heart transplantation
Heart transplantation samer kareem 2,283 Views • 2 years ago

Finding a donor heart can be difficult. The heart must be donated by someone who is brain-dead but is still on life support. The donor heart must be matched as closely as possible to your tissue type to reduce the chance that your body will reject it. You are put into a deep sleep with general anesthesia, and a cut is made through the breastbone. Your blood flows through a heart-lung bypass machine while the surgeon works on your heart. This machine does the work of your heart and lungs while they are stopped, and supplies your body with blood and oxygen. Your diseased heart is removed and the donor heart is stitched in place. The heart-lung machine is then disconnected. Blood flows through the transplanted heart, which takes over supplying your body with blood and oxygen. Tubes are inserted to drain air, fluid, and blood out of the chest for several days, and to allow the lungs to fully re-expand.

Can Oral Sex Increase Risk of Cancer?
Can Oral Sex Increase Risk of Cancer? Alicia Berger 19,850 Views • 2 years ago

Oral sex can be an enjoyable, healthy part of an adult relationship. But there are some things that many people don't know about oral sex. Here are four facts that might surprise you. 1. Oral sex is linked to throat cancer. Cancer? Yes, you can get throat cancer from oral sex, says American Cancer Society Chief Medical Officer Otis Brawley, MD. It's not oral sex, per se, that causes cancer, but the human papillomavirus (HPV), which can be passed from person to person during sex, including oral sex.

Risk Factors of Human Papillomavirus
Risk Factors of Human Papillomavirus samer kareem 6,118 Views • 2 years ago

In most cases, your body's immune system defeats an HPV infection before it creates warts. When warts do appear, they vary in appearance depending on which variety of HPV is involved: Genital warts. These appear as flat lesions, small cauliflower-like bumps or tiny stem-like protrusions. In women, genital warts appear mostly on the vulva but can also occur near the anus, on the cervix or in the vagina. In men, genital warts appear on the penis and scrotum or around the anus. Genital warts rarely cause discomfort or pain, though they may itch. Common warts. Common warts appear as rough, raised bumps and usually occur on the hands, fingers or elbows. In most cases, common warts are simply unsightly, but they can also be painful or susceptible to injury or bleeding.

GENITAL WARTS
GENITAL WARTS samer kareem 4,382 Views • 2 years ago

Genital warts are one of the most common types of sexually transmitted infections. At least half of all sexually active people will become infected with human papillomavirus (HPV), the virus that causes genital warts, at some point during their lives. Women are somewhat more likely than men to develop genital warts. As the name suggests, genital warts affect the moist tissues of the genital area. Genital warts may look like small, flesh-colored bumps or have a cauliflower-like appearance. In many cases, the warts are too small to be visible. Like warts that appear elsewhere on your body, genital warts are caused by the human papillomavirus (HPV). Some strains of genital HPV can cause genital warts, while others can cause cancer. Vaccines can help protect against certain strains of genital HPV

A meningioma is a tumor that arises from the meninges — the membranes that surround your brain and spinal cord. Most meningiomas are noncancerous (benign), though rarely a meningioma may be cancerous (malignant). Some meningiomas are classified as atypical, meaning they're neither benign nor malignant but, rather, something in between.

Arterial Anastomosis
Arterial Anastomosis samer kareem 1,730 Views • 2 years ago

Throughout the body, there are several points at which blood vessels unite. The junctions are termed anastomoses. In the simplest sense, an anastomosis is any connection (made surgically or occurring naturally) between tube-like structures. Naturally occurring arterial anastomoses provide an alternative blood supply to target areas in cases where the primary arterial pathway is obstructed. They are most abundant in regions of the body where the blood supply may can be easily damaged or blocked (such as the joints or intestines). This article focuses on the arterial anastomotic networks of the upper limb.

Sleep Apnea Surgery
Sleep Apnea Surgery samer kareem 1,587 Views • 2 years ago

This procedure, and other types of soft palate surgery, targets the back of the roof of your mouth. It involves removing and repositioning excess tissue in the throat to make the airway wider. The surgeon can trim down your soft palate and uvula, remove your tonsils, and reposition some of the muscles of the soft palate. UPPP and other soft palate procedures are the most common type of surgery for sleep apnea. But UPPP alone is unlikely to cure moderate to severe sleep apnea. It may be combined with surgeries that target other sites in the upper airway.

Diagnosis and Evaluation of COPD
Diagnosis and Evaluation of COPD samer kareem 1,776 Views • 2 years ago

To diagnose COPD, your doctor will probably do the following tests: Medical history and physical exam. These will give your doctor important information about your health. Lung function testsLung function tests, including an FEV1 test. These tests measure the amount of air in your lungs and the speed at which air moves in and out. Spirometry is the most important of these tests. Chest X-rayChest X-ray. This helps rule out other conditions with similar symptoms, such as lung cancer.

Special Anoscope for Easy Purse-string Suture Application in Stapled Hemorrhoidopexy
Special Anoscope for Easy Purse-string Suture Application in Stapled Hemorrhoidopexy Mohamed 34,839 Views • 2 years ago

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.
