How do you make a working human heart? Scientists can turn stem cells into beating heart cells, but getting them to organize into a 3D heart requires a scaffold. At the Massachusetts General Hospital in Boston, Harald Ott and his team are reusing the scaffold that nature provides. They’re stripping away all the living cells from dead hearts, before filling in the leftover matrix with healthy new cells. In this video, Brendan Maher finds out how the technique could be used to develop parts of the heart, like the aortic root and valve, for transplant.
Meckel's Diverticulum is a vestigeal remnant of vitellointestinal duct. Its a true diverticulum as it contains all three layers of intestine. It is usually presents at anti mesenteric burder. Usually 2 cm (range 1- 12 cm ) in length, found in 2 % of population , and situated around 2 feet of Ileaocecal junction. 50 % cases it contains gastric mucosa , but may also contain colonic, duodenal or pancreatic mucosa .male : female ration in symptomatic cases is 3 : 1.It may mimic acute appendicitis, so in cases where one is going for surgery for appendicitis , must search for meckel's diverticulum........
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.
Patient 65-year-old of age who comes to the medical consultation with pain moderated pain in the right hypochondrium of “several years of evolution” but that it increased one week ago. Also, she shows pain in the umbilical region of “many years of evolution”, that is supported according to the patient - in a constant way.rnTo the examination, we observe an umbilical hernia, apparently divided into two parts. The hernia of the external region measures 25.1 centimeters x 18.0 centimeters and the one that occupies the average region measures 12.0 centimeters x 10.0 centimeters.rnPatient who comes to the medical consultation with moderated pain in the right hypochondrium of one year of evolution but it increased one week ago after eat duck.rnIn the ultrasound scan of the region of the right hypochondrium (patient came having breakfast, that is to say, without previous preparation ) we can observe the liver of 123.8 millimeters high, as well as the porta vein with a diameter of 7.3 millimeters.rnOn having observed the Gallbladder, we think that a side wall is increased in 2.7 mm (hyperechogenic) with several “echogenics points” in the interior (”Biliary Mud”).
The measurements of the gallbladder were: 39.0 x 17.4 millimeters.rnWe can appreciates an echogenic image in the interior that it would make think about stone. The stones are identified as echogenic foci casting acoustic shadowing but but this image did not appear and a re-evaluation is decided in 15 days.
Acalculous cholecystopathy which means disease or condition of the gallbladder without the presence of gallstones. You might also call it functional gallbladder disorder or impaired gallbladder emptying. Some causes may be chronic inflammation, a problem with the smooth muscles of the gallbladder or the muscle of the Sphincter of Oddi being too tight.
REMEMBER:
Umbilical hernia is a congenital malformation, especially common in infants of African descent, and more frequent in boys. An Acquired umbilical hernia directly results from increased intra-abdominal pressure and are most commonly seen in obese individuals.
Presentation:A hernia is present at the site of the umbilicus (commonly called a navel, or belly button) in the newborn; although sometimes quite large, these hernias tend to resolve without any treatment by around the age of 5 years. Obstruction and strangulation of the hernia is rare because the underlying defect in the abdominal wall is larger than in an inguinal hernia of the newborn. The size of the base of the herniated tissued is inversely correlated with risk of strangulation (i.e. narrow base is more likely to strangulate).
Babies are prone to this malformation because of the process during fetal development by which the abdominal organs form outside the abdominal cavity, later returning into it through an opening which will become the umbilicus.
Differential diagnosisrnImportantly this type of hernia must be distinguished from a paraumbilical hernia which occurs in adults and involves a defect in the midline near to the umbilicus, and from omphalocele.
procedure is usually done in the hospital or outpatient surgical center under general anesthesia (while you are asleep and pain-free). The procedure is performed in the following way: The surgeon makes a small cut (incision) below the belly button (navel). A needle or tube is inserted into the incision. Carbon dioxide gas is passed into the abdomen through the needle or tube. The gas helps expand the area, giving the surgeon more room to work, and helping the surgeon see the organs more clearly. A tube is placed through the cut in your abdomen. A tiny video camera (laparoscope) goes through this tube and is used to see the inside of your pelvis and abdomen. More small cuts may be made if other instruments are needed to get a better view of certain organs. If you are having gynecologic laparoscopy, dye may be injected into your cervix area so the surgeon can view your fallopian tubes. After the exam, the gas, laparoscope, and instruments are removed, and the cuts are closed. You will have bandages over those areas.
Electrical cardioversion is a procedure in which an electric current is used to reset the heart's rhythm back to its regular pattern (normal sinus rhythm). The low-voltage electric current enters the body through metal paddles or patches applied to the chest wall.
Chemotherapy (often abbreviated to chemo and sometimes CTX or CTx) is a category of cancer treatment that uses chemical substances, especially one or more anti-cancer drugs (chemotherapeutic agents) that are given as part of a standardized chemotherapy regimen.
If you have been diagnosed with a bulging disc, you are not alone. Bulging discs, also known as a disc protrusion, are a very common occurrence. They usually remain asymptomatic; however, they can cause discomfort and disability in various parts of the body if the disc compresses an adjacent nerve root or the spinal cord. As we age, the outer fibrous portion of our discs can weaken. Pressure from the central core of the disc can then stretch to the outer rim, causing the disc to bulge. If left untreated, the disc can continue to bulge until it tears, which is classified as a herniated disc.
A lipoma is a growth of fat cells in a thin, fibrous capsule usually found just below the skin. Lipomas aren't cancer and don't turn into cancer. They are found most often on the torso, neck, upper thighs, upper arms, and armpits, but they can occur almost anywhere in the body. One or more lipomas may be present at the same time.
