This video shows management of rupture of the posterior capsule post blunt trauma in a child aged 8. Pre-operative suspicion of PCR was strong because of a flat anterior. So we were careful in our approach from the very beginning. CCC was performed and then dry aspiration of lens matter initiated. Sice vitreous showed, so anterior vitrectomy was done along with systematic removal of the lens matter. An acrysof multi-component lens was implanted into the sulcus and optic captured into the CCC.Outcome was very good.

Intestinal malrotation is a developmental anomaly that occasionally causes an unusual array of symptoms in adults. The delay in diagnosis that is common in patients with malrotation frequently results in a ruptured appendix. Appendicitis should be considered when characteristic signs and symptoms are present, even if the location of abdominal pain is atypical.
Children are not little adults, which is why even the simplest of procedures requires a hospital that is 100 percent dedicated to caring for children. Children’s Mercy is one of only 10 centers in the country to be as recognized as a Level 1 Children’s Surgery Center, the highest possible rating. The result? An organization with pediatrics specialists in every subspecialty that sets the standard of care instead of just practicing it.
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........
Emphysema gradually damages the air sacs (alveoli) in your lungs, making you progressively more short of breath. Emphysema is one of several diseases known collectively as chronic obstructive pulmonary disease (COPD). Smoking is the leading cause of emphysema. Your lungs' alveoli are clustered like bunches of grapes. In emphysema, the inner walls of the air sacs weaken and eventually rupture — creating one larger air space instead of many small ones. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream. When you exhale, the damaged alveoli don't work properly and old air becomes trapped, leaving no room for fresh, oxygen-rich air to enter. Treatment may slow the progression of emphysema, but it can't reverse the damage.
Acute bronchitis and pneumonia share many of the same symptoms, and some people with acute bronchitis are at risk for getting pneumonia. Although acute bronchitis usually goes away within a few weeks, pneumonia can be a serious condition, especially in older adults. The following table outlines some differences between acute bronchitis and pneumonia. There are variations in symptoms of both conditions, so if you think you might have pneumonia, always check with your doctor.
A modified radical mastectomy is a procedure in which the entire breast is removed, including the skin, areola, nipple, and most axillary lymph nodes; the pectoralis major muscle is spared. Historically, a modified radical mastectomy was the primary method of treatment of breast cancer. [1, 2] As the treatment of breast cancer evolved, breast conservation has become more widely used. [3, 4] However, mastectomy still remains a viable option for women with breast cancer. [5, 6]
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.
Binding and Fusion: HIV begins its life cycle
when it binds to a CD4 receptor and one of two
co-receptors on the surface of a CD4+
Tlymphocyte. The virus then fuses with the host
cell. After fusion, the virus releases RNA, its
genetic material, into the host cell.
Reverse Transcription: An HIV enzyme
called reverse transcriptase converts the singlestranded HIV RNA to double-stranded HIV DNA.
Integration: The newly formed HIV DNA
enters the host cell's nucleus, where an HIV
enzyme called integrase "hides" the HIV DNA
within the host cell's own DNA. The integrated
HIV DNA is called provirus. The provirus may
remain inactive for several years, producing few or
no new copies of HIV
Transcription: When the host cell receives a
signal to become active, the provirus uses a host
enzyme called RNA polymerase to create copies of
the HIV genomic material, as well as shorter
strands of RNA called messenger RNA (mRNA).
The mRNA is used as a blueprint to make long
chains of HIV proteins.
Assembly: An HIV enzyme called protease cuts
the long chains of HIV proteins into smaller
individual proteins. As the smaller HIV proteins
come together with copies of HIV's RNA genetic
material, a new virus particle is assembled.
Budding: The newly assembled virus pushes out
("buds") from the host cell. During budding, the new
virus steals part of the cell's outer envelope. This
envelope, which acts as a covering, is studded with
protein/sugar combinations called HIV
glycoproteins. These HIV glycoproteins are
necessary for the virus to bind CD4 and coreceptors. The new copies of HIV can now move
on to infect other cells.
Ewing's sarcoma typically occurs in children and young adults. It often begins in the legs, bones of the pelvis, and arms. Bone pain, localized swelling, and tenderness are symptoms. In rare cases bone fractures may also be found. Treatments include chemotherapy, surgery, and radiation.
Many mothers notice engorgement, or over-filled breasts, at some point or the other while they are breast-feeding their baby and it is especially common to experience when your baby is first born and you are just starting to make milk. So for the first couple of days you make colostrum and then 2-5 days later your milk comes in. And sometimes it comes in with a vengeance and all of the sudden you feel really full and it can be painful and very uncomfortable. Normally your milk supply will even out and start to work well with your babys demand, so it is kind of a supply and demand type of function, but until then, if you feel engorgement, there are a few things you can do to relieve it. If you are nursing your baby on demand this will usually help to self-regulate and most young babies want to eat every 2-3 hours and sometimes even every hour. So, basically, the more often your breasts are emptied the more relief you will feel. But on the same hand, the more you nurse the more milk your body will probably produce. This is why it is good to go off of your babys cues because then you will make what your baby needs and hopefully not much more. But if you are making more than your baby needs and you find that you are still full after feedings you will probably have to either manually express some milk or pump it off, so have a good pump available in case you need to, and if you don't, you can manually express the milk by gently massaging from the armpit down towards the nipple. And you can also try using heat prior to nursing your baby or pumping milk off and this will also help to relax things and help you to get the milk out. Take a warm shower and then feed your baby or use a warm compress.
