ow does a perforation of the eardrum occur? There are many ways an eardrum perforation can occur. An infection behind the eardrum in the middle ear may cause a rupture of the eardrum. Trauma to the ear may result from an object entering the ear canal and puncturing the eardrum. A traumatic blow to the ear with a cupped hand can rupture the eardrum. Hot welding slag can burn a hole through the eardrum. After a ventilation tube has been extruded or is removed, the opening usually closes; in some cases a permanent opening of the eardrum may occur. Chronic ear problems such as deep retraction pockets and cholesteatoma can weaken and erode the eardrum, resulting in a defect or perforation.
Hepatitis and chronic alcohol abuse are frequent causes. Liver damage caused by cirrhosis can't be undone, but further damage can be limited. Initially patients may experience fatigue, weakness, and weight loss. During later stages, patients may develop jaundice (yellowing of the skin), gastrointestinal bleeding, abdominal swelling, and confusion. Treatments focus on the underlying cause. In advanced cases, a liver transplant may be needed.
How Does a Bone Heal? All broken bones go through the same healing process. This is true whether a bone has been cut as part of a surgical procedure or fractured through an injury. The bone healing process has three overlapping stages: inflammation, bone production and bone remodeling. Inflammation starts immediately after the bone is fractured and lasts for several days. When the bone is fractured, there is bleeding into the area, leading to inflammation and clotting of blood at the fracture site. This provides the initial structural stability and framework for producing new bone. Diagram of inflammation in a fractured bone Bone production begins when the clotted blood formed by inflammation is replaced with fibrous tissue and cartilage (known as soft callus). As healing progresses, the soft callus is replaced with hard bone (known as hard callus), which is visible on x-rays several weeks after the fracture. Bone remodeling, the final phase of bone healing, goes on for several months. In remodeling, bone continues to form and becomes compact, returning to its original shape. In addition, blood circulation in the area improves. Once adequate bone healing has occurred, weightbearing (such as standing or walking) encourages bone remodeling.
Perineal repair after episiotomy or spontaneous obstetric laceration is one of the most common surgical procedures. Potential sequelae of obstetric perineal lacerations include chronic perineal pain,1 dyspareunia,2 and urinary and fecal incontinence.3–5 Few studies of laceration repair techniques exist to support the development of an evidence-based approach to perineal repair. This article discusses a repair method that emphasizes anatomic detail, with the expectation that an anatomically correct perineal repair may result in a better long-term functional outcome.

Laparoscopic Ovarian Drilling (LOD)
A surgical treatment for women with PCOS
Women with PCOS usually have ovaries with a thick outer layer.
Ovarian drilling works by breaking through the thick outer surface and lowering the amount of testosterone made by the ovaries
A small incision is made in the abdomen.
Carbon dioxide gas is used to inflate the abdomen.
Very small holes are made in the ovaries.
Ovarian drilling can help restore ovulation and improve the chances of becoming pregnant.

Nearly 300 million people experience the world without certain colors every day. ‘Color For the Colorblind’ is a short documentary about what happened when we partnered with EnChroma, maker of color blindness-correcting glasses, to help people experience colors for the first time.
Highlights of a fetal laser surgery for twin-to-twin transfusion syndrome (TTTS) will be shown from Tampa General Hospital
TTTS affects 10 to 15 percent of identical-twin pregnancies and is the result of abnormal blood exchange between identical twins through a common placenta. The larger of the twins, or recipient, is surrounded by too much amniotic fluid and in danger of heart failure as its body tries to pump the overwhelming volume of blood intended for both. The smaller, or donor twin, is encased in a shrinking amniotic sac deprived of blood. Without treatment, both will likely die.
Rubén Quintero, M.D., Medical Director of Maternal Fetal Medicine/Fetal Surgery at Tampa General Hospital and Professor and Director of the Division of Maternal Fetal Medicine, Department of Obstetrics and Gynecology, University of South Florida College of Medicine will narrate the procedure and answer e-mail questions live as taped highlights of the procedure are shown.
