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.
A man's age matters. As men get older, the chances of conceiving and having a healthy child decline. Male fertility starts to decline after 40 when sperm quality decreases. This means it takes longer for their partners to conceive and when they do, there's an increased risk of miscarriage.
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.
Shane Shapiro, M.D., orthopedic physician at Mayo Clinic in Florida, performs a bone marrow aspiration and concentration for BMAC/stem cell injection into arthritic knees. This procedure is part of a Mayo Clinic IRB approved, FDA monitored clinical research trial which can be searched on at http://ClinicalTrials.gov.
Mayo Clinic and the Mayo Center for Regenerative Biotherapeutics is studying biologically based non-surgical treatments for osteoarthritis. One such treatment is the harvesting of the patient's own stem cells from their bone marrow.
"In our procedure we draw cellular rich bone marrow from both sides of the pelvis. We then filter the resulting product and concentrate the stem cells and their corresponding growth factors. Using an ultrasound to image the knee joint, we are then able to precisely inject the cells into the arthritic knee. We are currently demonstrating that this procedure is safe and can relieve pain. We also hope to be able to slow the progression of the degenerative joint disease and perhaps one day regrow cartilage in the arthritic joint."

soaking the wound in cool water for five minutes or longer. taking acetaminophen or ibuprofen for pain relief. applying lidocaine (an anesthetic) with aloe vera gel or cream to soothe the skin. using an antibiotic ointment and loose gauze to protect the affected area.
St. Luke's originally broadcast this live in a webcast and later re-purposed it for air on KCRG-TV9 as an educational video. It is hosted by Ashley Hinson, KCRG-TV9 anchor and Dr. Sandeep Munjal. Dr. Jeff Nassif performs the knee replacement surgery on an eastern Iowa woman. St. Luke's has a rapid recovery joint replacement program, which gets people back to life quickly after surgery.
The video is about the evolution of the anatomic UCLA laparoscopic technique over 1325 cases and demonstrates the key steps of our operation to improve patient safety and outcomes.

This is an example of a surgery to fix a femur (thigh bone) fracture utilizing an intramedullary nail. This is a minimally invasive way of fixing this surgical problem and allows for immediate range of motion and full weight-bearing.
A spinal tumor is a growth that develops within your spinal canal or within the bones of your spine. It may be cancerous or noncancerous. Tumors that affect the bones of the spine (vertebrae) are known as vertebral tumors. Tumors that begin within the spinal cord itself are called spinal cord tumors. There are two main types of tumors that may affect the spinal cord: Intramedullary tumors begin in the cells within the spinal cord itself, such as astrocytomas or ependymomas. Extramedullary tumors develop within the supporting network of cells around the spinal cord. Although they don't begin within the spinal cord itself, these types of tumors may affect spinal cord function by causing spinal cord compression and other problems. Examples of extramedullary tumors that can affect the spinal cord include schwannomas, meningiomas and neurofibromas.
Uterine fibroids are noncancerous growths of the uterus that often appear during childbearing years. Also called leiomyomas (lie-o-my-O-muhs) or myomas, uterine fibroids aren't associated with an increased risk of uterine cancer and almost never develop into cancer. Fibroids range in size from seedlings, undetectable by the human eye, to bulky masses that can distort and enlarge the uterus. You can have a single fibroid or multiple ones. In extreme cases, multiple fibroids can expand the uterus so much that it reaches the rib cage. Many women have uterine fibroids sometime during their lives. But most women don't know they have uterine fibroids because they often cause no symptoms. Your doctor may discover fibroids incidentally during a pelvic exam or prenatal ultrasound.
A central venous catheter, also called a central line, is a long, thin, flexible tube used to give medicines, fluids, nutrients, or blood products over a long period of time, usually several weeks or more. A catheter is often inserted in the arm or chest through the skin into a large vein.
In as many as 80% of cases, doctors don’t find the exact reason for a curved spine. Scoliosis without a known cause is what doctors call “idiopathic.” Some kinds of scoliosis do have clear causes. Doctors divide those curves into two types -- structural and nonstructural. In nonstructural scoliosis, the spine works normally, but looks curved. Why does this happen? There are a number of reasons, such as one leg’s being longer than the other, muscle spasms, and inflammations like appendicitis. When these problems are treated, this type of scoliosis often goes away.

#LaparoscopicColectomy #ColonSurgery #LargeIntestine
A colectomy is usually done to treat diseases that inflame your colon, a bowel obstruction, colon cancer, or a damaged or injured colon. The anatomy of the colon, and the laparoscopic procedure done to remove a portion of the colon, are depicted.
