Dilation And Curettage Uterus
Dilation And Curettage Uterus samer kareem 14,700 Views • 2 years ago

Dilation and curettage (D&C) is a procedure to remove tissue from inside your uterus. Doctors perform dilation and curettage to diagnose and treat certain uterine conditions — such as heavy bleeding — or to clear the uterine lining after a miscarriage or abortion. In a dilation and curettage — sometimes spelled "dilatation" and curettage — your doctor uses small instruments or a medication to open (dilate) your cervix — the lower, narrow part of your uterus. Your doctor then uses a surgical instrument called a curette to remove uterine tissue. Curettes used in a D&C can be sharp or use suction

What is frontotemporal dementia?
What is frontotemporal dementia? samer kareem 1,915 Views • 2 years ago

Frontotemporal dementia is the name for a range of conditions in which cells in the frontal and temporal lobes of the brain are damaged. These lobes control behaviour, emotional responses and language. This means that people will experience changes in personality and behaviour, or may struggle with language – for example, in finding the right word. Frontotemporal dementia is a less common form of dementia which is more likely to affect younger people – those under 65.

What is syndrome of inappropriate antidiuretic hormone (SIADH)? Well, SIADH is a condition where too much ADH hormone is released, which causes an increase in blood volume and ultimately leads to a series of complications related to the blood osmolality and osmolarity

Correction of knock knee deformity
Correction of knock knee deformity samer kareem 1,917 Views • 2 years ago

This is a technique of correcting knock knee (genu valgum) deformity by surgery. Highligh of the technique is that the bone is not cut, but merely weakened. The advantage is that it provides accuracy to the surgeon, and rapid healing. Once corrected, the bone is held in place with a special plate (Tomofix), which permits walking with crutches the very next day.

Epidural Anesthesia
Epidural Anesthesia samer kareem 14,525 Views • 2 years ago

If you’re considering an epidural to help manage the pain of childbirth, you’re not alone. More than 60 percent of women delivering at hospitals elect for an epidural during labor. And with good reason: An epidural is considered one of the safest methods of pain control, with just one in 3,000 pregnancies experiencing serious complications. It’s also good for you, since you’ll remain awake and alert during the birth, as well as for your baby, since the drugs will barely reach your bloodstream (so they can’t get into hers).

Keyhole Brain Surgery
Keyhole Brain Surgery samer kareem 1,685 Views • 2 years ago

Retro-sigmoid craniotomy (often called "keyhole" craniotomy) is a minimally-invasive surgical procedure performed to remove brain tumors. This procedure allows for the removal of skull base tumors through a small incision behind the ear, providing access to the cerebellum and brainstem. Neurosurgeons may use this approach to reach certain tumors, such as meningiomas and acoustic neuromas (vestibular schwannomas).

Minimally Invasive Parotidectomy
Minimally Invasive Parotidectomy samer kareem 2,053 Views • 2 years ago

Minimally invasive parotid surgery techniques are currently utilized here in Atlanta by our practice to allow the same operation to be performed with no permanent visible incision on the face or the neck. In addition to being more cosmetically appealing, this approach is less painful and allows the procedure to be performed as an outpatient. Most patients take pain medication for only a day or two after surgery.

How Ultrasound works
How Ultrasound works samer kareem 2,528 Views • 2 years ago

Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves and their echoes. The technique is similar to the echolocation used by bats, whales and dolphins, as well as SONAR used by submarines. In ultrasound, the following events happen: The ultrasound machine transmits high-frequency (1 to 5 megahertz) sound pulses into your body using a probe. The sound waves travel into your body and hit a boundary between tissues (e.g. between fluid and soft tissue, soft tissue and bone). Some of the sound waves get reflected back to the probe, while some travel on further until they reach another boundary and get reflected. The reflected waves are picked up by the probe and relayed to the machine. The machine calculates the distance from the probe to the tissue or organ (boundaries) using the speed of sound in tissue (5,005 ft/s or1,540 m/s) and the time of the each echo's return (usually on the order of millionths of a second). The machine displays the distances and intensities of the echoes on the screen, forming a two dimensional image like the one shown below.

Ureteral Stenting
Ureteral Stenting samer kareem 3,396 Views • 2 years ago

Ureteral stents are one of the most common devices used by urologists. They are placed with cystoscopic guidance in an operating room setting. Ureteral stents are used to relieve ureteral obstruction, promote ureteral healing following surgery, and to assist with ureteral identification during pelvic surgery. Ureteral stent placement is associated with some degree of morbidity in the majority of patients that ranges from generalized urinary discomfort to urinary tract infection or obstruction. Much of the morbidity is related to the biocompatibility of the materials used to fashion the stent and, to some extent, their design; unfortunately, the ideal stent has yet to be discovered.

Gastrostomy tube is placed when a patient is not able to eat on his/her own as a result of neurological or other dysfunction. There are many different types of gastrostomy tubes but in general there are two bigger categories. The classic one and the low profile one. The gastroplexy technique is used preferably to avoid accidental pulling of the gastrostomy tube from an agitated or confused patient.

Barrett esophagus Therapy
Barrett esophagus Therapy samer kareem 3,562 Views • 2 years ago

Barrett's esophagus is a complication of chronic (long lasting) and usually severe gastrointestinal reflux disease (GERD), but occurs in only a small percentage of patients with GERD. Criteria are needed for screening patients with GERD for Barrett's esophagus. Until validated criteria are available, it seems reasonable to do screening endoscopies in GERD patients who cannot be taken off acid suppression therapy after two to three years. The diagnosis of Barrett's esophagus rests upon seeing (at endoscopy) a pink esophageal lining that extends a short distance (usually less than 2.5 inches) up the esophagus from the gastroesophageal junction and finding intestinal type cells (goblet cells) on biopsy of the lining. There is a small but definite increased risk of cancer of the esophagus (adenocarcinoma) in patients with Barrett's esophagus.

Beta-blockers, also known as beta antagonists, beta-adrenergic blocking agents, or beta-adrenergic antagonists, are drugs that are prescribed to treat several different types of conditions, including hypertension (high blood pressure), angina, some abnormal heart rhythms, heart attack (myocardial infarction), anxiety, migraine, glaucoma, and overactive thyroid symptoms.

How Do You Get Hepatitis A?
How Do You Get Hepatitis A? samer kareem 1,169 Views • 2 years ago

The hepatitis A virus, which causes the infection, usually is spread when a person ingests even tiny amounts of contaminated fecal matter. The hepatitis A virus infects liver cells and causes inflammation. The inflammation can impair liver function and cause other signs and symptoms of hepatitis A. Hepatitis A virus can be transmitted several ways, such as: Eating food handled by someone with the virus who doesn't thoroughly wash his or her hands after using the toilet Drinking contaminated water Eating raw shellfish from water polluted with sewage Being in close contact with a person who's infected — even if that person has no signs or symptoms Having sex with someone who has the virus

Treating Scoliosis with Magnets
Treating Scoliosis with Magnets samer kareem 18,017 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.
