Ovarian teratoma is a type of germ cell tumour. Germ cell tumours are cancers that begin in egg cells in women or sperm cells in men. There are 2 main types of ovarian teratoma. Mature teratoma, which is benign. Immature teratoma, which is cancerous.

Encopresis is a problem that children age four or older can develop due to chronic (long-term) constipation. With constipation, children have fewer bowel movements than normal, and the bowel movements they do have can be hard, dry, and difficult to pass. The child may avoid using the bathroom to avoid discomfort.

Esophageal atresia is an abnormality, or birth defect, of the esophagus that occurs early in pregnancy, as the baby is developing. The esophagus forms in the first few months of fetal life as a long, hollow, continuous tube joining the mouth to the stomach. In newborns with this birth defect, formation of this continuous esophageal tube is interrupted. esophageal-artresia-2In most cases, two separate tubes are formed, an upper (proximal) tube connected to the mouth and a lower (distal) tube connected to the stomach. This seperated tubes are sealed off creating a pouch on either side; the gap between these pounches can be short or very long. Saliva can accumulate in the upper pouch as it cannot drain into the stomach.

Functional endoscopic sinus surgery is a minimally invasive surgical treatment which uses nasal endoscopes to enlarge the nasal drainage pathways of the paranasal sinuses to improve sinus ventilation.

This video is brought to you by the Stanford Medicine 25 to teach you the common causes of shoulder pain and how to diagnose them by the physical exam.

The Stanford Medicine 25 program for bedside medicine at the Stanford School of Medicine aims to promote the culture of bedside medicine to make current and future clinicians and other healthcare provides better at the art of physical diagnosis and more confident at the bedside of their patients.

Surgical site infections (SSIs) remain a prevalent threat to patient safety. Proper surgical hand scrub or rub techniques are essential to decreasing the incidence of SSIs. This video provides instructions on the anatomical surgical hand scrub procedure using the brushstroke method.

Transgender Man Gives Birth to Healthy Baby, Talks Navigating Pregnancy as a Man Trystan Reese is a transgender man who just gave birth to a healthy baby boy. He told us about his pregnancy—and why his story isn't so out of the ordinary.

Pulmonary function tests are a broad range of tests that measure how well the lungs take in and exhale air and how efficiently they transfer oxygen into the blood. Spirometry measures how well the lungs exhale.

A water birth means at least part of your labor, delivery, or both happen while you’re in a birth pool filled with warm water. It can take place in a hospital, a birthing center, or at home. A doctor, nurse-midwife, or midwife helps you through it. In the U.S., some birthing centers and hospitals offer water births. Birthing centers are medical facilities that offer a more homelike setting than a hospital and more natural options for women having babies. The use of a birthing pool during the first stage of labor might: Help ease pain Keep you from needing anesthesia Speed up your labor The American College of Obstetricians and Gynecologists (ACOG), which sets guidelines for pregnancy and childbirth care in the U.S., says a water birth during the first stage of labor may have some benefits but delivering your baby underwater should be considered an experimental procedure with risks. The first stage is from when contractions start until your cervix is fully dilated.

The male reproductive system includes the scrotum, testes, spermatic ducts, sex glands, and penis. These organs work together to produce sperm, the male gamete, and the other components of semen.

49-years old patient complaining of cough, fever and pleuritic pain for 2 weeks. At admission he was febrile and tachypnic. Chest X-Ray showed left pleural effusion. Thoracocentesis revealed purulent fluid. Chest CT-scan showed large and loculated left pleural effusion and pleural thickening. VATS decortication was performed through three incisions.

A 55-year-old man presented with recurrent epistaxis. After endoscopic sphenopalatine artery cauterization, the bleeding stopped. The patient was doing well at last follow up.

Endovascular Aneurysm Repair Endovascular aneurysm repair (or endovascular aortic repair) (EVAR) is a type of endovascular surgery used to treat pathology of the aorta, most commonly an abdominal aortic aneurysm (AAA).

A clavicle fracture is a bone fracture in the clavicle, or collarbone. It is often caused by a fall onto an outstretched upper extremity, a fall onto a shoulder, or a direct blow to the clavicle. Many research projects are underway regarding the medical healing process of clavicle fractures.

A brain (cerebral) aneurysm is a bulging, weak area in the wall of an artery that supplies blood to the brain. In most cases, a brain aneurysm causes no symptoms and goes unnoticed. In rare cases, the brain aneurysm ruptures, releasing blood into the skull and causing a stroke. When a brain aneurysm ruptures, the result is called a subarachnoid hemorrhage. Depending on the severity of the hemorrhage, brain damage or death may result. The most common location for brain aneurysms is in the network of blood vessels at the base of the brain called the circle of Willis. What causes a brain aneurysm? A person may inherit the tendency to form aneurysms, or aneurysms may develop because of hardening of the arteries (atherosclerosis) and aging. Some risk factors that can lead to brain aneurysms can be controlled, and others can't. The following risk factors may increase your risk for an aneurysm or, if you already have an aneurysm, may increase your risk of it rupturing: Family history. People who have a family history of brain aneurysms are more likely to have an aneurysm than those who don't. Previous aneurysm. People who have had a brain aneurysm are more likely to have another. Gender. Women are more likely to develop a brain aneurysm or to suffer a subarachnoid hemorrhage. Race. African Americans are more likely than whites to have a subarachnoid hemorrhage. High blood pressure. The risk of subarachnoid hemorrhage is greater in people who have a history of high blood pressure. Smoking. In addition to being a cause of high blood pressure, the use of cigarettes may greatly increase the chances of a brain aneurysm rupturing.

Alcoholic hepatitis can occur in people who drink heavily for many years. Symptoms include yellow skin and eyes along with increasing belly size due to fluid accumulation. Treatment involves hydration, nutritional care, and stopping alcohol use. Steroid drugs can help reduce liver inflammation.

LASIK eye surgery is commonly performed laser refractive surgery to correct vision problems. This 3d animation shows how laser-assisted in situ keratomileusis (lasik) can be an alternative to glasses or contact lenses.

It’s one of many vision correction surgeries that work by reshaping your cornea, the clear front part of your eye, so that light focuses on the retina in the back of your eye.

In eyes with normal vision, the cornea bends (refracts) light precisely onto the retina at the back of the eye. But with nearsightedness (myopia), farsightedness (hyperopia) or astigmatism, the light is bent incorrectly, resulting in blurred vision.

During LASIK surgery, a special type of cutting laser is used to precisely change the shape of the dome-shaped clear tissue at the front of your eyes (cornea) to improve vision.

Glasses or contact lenses can correct vision, but reshaping the cornea itself also will provide the necessary refraction.

Biceps tenodesis surgery is performed when the biceps tendon is damaged, or the rotator cuff tendon or cartilage ring in the shoulder is torn. The biceps tendon is a strong rope‐like structure connecting the upper end of the biceps muscle to the bones in the shoulder. In biceps tenodesis surgery, the biceps tendon is separated from the shoulder and reattached to the humerus, or the upper arm bone.
