Colonoscopy Procedure
Colonoscopy Procedure samer kareem 9,135 Views • 2 years ago

The camera sends images to an external monitor so the doctor can study the inside of your colon. The doctor can also insert instruments through the channel to take tissue samples (biopsies) or remove polyps or other areas of abnormal tissue. A colonoscopy typically takes about 20 minutes to an hour.

Treating Scoliosis with Magnets
Treating Scoliosis with Magnets samer kareem 18,009 Views • 2 years ago

Pediatric orthopedic surgeons at Columbia are using a new device with magnetic technology that avoids the need for multiple spine-lengthening surgeries to correct early-onset scoliosis, a severe curvature of the spine in young children. In April 2014, Michael Vitale, MD, the Ana Lucia Professor of Pediatric Orthopedic Surgery at CUMC and 1995 graduate of P&S, performed the first procedure in the New York area, using the device to treat a 5-year-old boy. When braces and casts cannot control scoliosis in young children, surgeons turn to growing rods, which help correct the curve while allowing the spine to grow. When spinal maturity is near, the rods are removed and a spinal fusion can be performed. But during years of treatment with growing rods, patients must undergo surgery every six months to lengthen the rods to keep up with the patients’ growth. A patient may undergo eight to 10 procedures, which are costly and result in lost time for parents at work and children at school. The new device—MAGEC (MAGnetic Expansion Control) rods—contains a mechanism inside the growing rods that allows surgeons to lengthen the rods with a handheld external magnet, without surgery.

Chalazion Removal
Chalazion Removal samer kareem 19,090 Views • 2 years ago

Chalazions are extremely common, and having a sound surgical technique to drain a chalazion is a fundamental in general ophthalmology and oculoplastic surgery. I believe one of the biggest downfalls in treating chalazions is inadequate local anesthetic. Please that both the outer and inner surface to the eyelid need to receive local anesthesia to make the patient totally comfortable. It is important to be careful in delivering the local anesthetic and making sure you have control of the head position, and the position of your needle is bent to minimize any possibility of contact with the globe.

Frostbite is an injury caused by freezing of the skin and underlying tissues. First your skin becomes very cold and red, then numb, hard and pale. Frostbite is most common on the fingers, toes, nose, ears, cheeks and chin. Exposed skin in cold, windy weather is most vulnerable to frostbite. But frostbite can occur on skin covered by gloves or other clothing.

Pregnant and non-pregnant vaginal discharge
Pregnant and non-pregnant vaginal discharge samer kareem 12,486 Views • 2 years ago

A lot of women want to know what type of vaginal discharge is normal during pregnancy, and when you're not pregnant. So let's start out by talking about what's normal when you're not pregnant. It's normal to have about 1/2 teaspoon to 1 teaspoon of whitish, creamy, tannish discharge on most days of your cycle in between periods, with the exception of the time of ovulation. Actually, around the time of ovulation, it's normal to notice the discharge becoming more slippery and clear, almost like egg whites. And this is actually a sign that you can watch for to know when you're ovulating. And if you're seeing this type of discharge and you're trying to have a baby, then you should start to time intercourse with ovulation to increase your chances of conceiving.

Instead of permanently joining (fusing) vertebrae with metal rods and screws, and therefore restricting movement, the new procedure uses the Anatomic Facet Replacement System (AFRS) device that attaches to each of two adjacent vertebrae with a movable joint that mimics the spine's natural joint.

Devastating Consequences of Tooth Loss
Devastating Consequences of Tooth Loss samer kareem 10,397 Views • 2 years ago

Tooth loss can make you look older. When you lose a tooth and don’t replace it with a dental implant, you risk the chance of jawbone loss. Normally, your tooth root stimulates the continued growth and health of your jawbone. Dental implants mirror your natural tooth root and keep your jawbone healthy.

Giant cell tumour is a locally aggressive primary bone tumour, located eccentrically in the metaphysis and epiphysis of a long bone. It commonly affects distal end of Femur, proximal end of Tibia and distal end of Radius. It is occasionally reported in small bones of hand and foot[1], spine[2] and pelvis[3]. Though it occurs in 20 - 35 year old individuals commonly, it can also be seen in children as young as 2 years[4] and also in older individuals

The development of the gastrointestinal tract
The development of the gastrointestinal tract samer kareem 2,513 Views • 2 years ago

The gastrointestinal tract (GIT) arises initially during the process of gastrulation from the endoderm of the trilaminar embryo (week 3) and extends from the buccopharyngeal membrane to the cloacal membrane. The tract and associated organs later have contributions from all the germ cell layers. During the 4th week three distinct regions (fore-, mid- and hind-gut) extend the length of the embryo and will contribute different components of the GIT. The large mid-gut is generated by lateral embryonic folding which "pinches off" a pocket of the yolk sac, the 2 compartments continue to communicate through the vitelline duct. The oral cavity (mouth) is formed following breakdown of the buccopharyngeal membrane (oropharyngeal or oral membrane) and contributed to mainly by the pharynx lying within the pharyngeal arches (More? Head Development). Loss of buccopharyngeal membrane opens the tract to amniotic fluid through the remainder of development, and during the fetal period is actively swallowed.

This form of liver cancer is called primary liver cancer. Noncancerous, or benign, liver tumors are common. They do not spread to other areas of the body, and they usually do not pose a serious health risk. In most cases, benign liver tumors are not detected because they cause no symptoms.
