Retinoblastoma is an eye cancer that begins in the retina — the sensitive lining on the inside of your eye. Retinoblastoma most commonly affects young children, but can rarely occur in adults. Your retina is made up of nerve tissue that senses light as it comes through the front of your eye. The retina sends signals through your optic nerve to your brain, where these signals are interpreted as images. A rare form of eye cancer, retinoblastoma is the most common form of cancer affecting the eye in children. Retinoblastoma may occur in one or both eyes.

Homocystinuria is an inherited disorder that affects the metabolism of the amino acid methionine. Amino acids are the building blocks of life. Causes Homocystinuria is inherited in families as an autosomal recessive trait. This means that the child must inherit a non-working copy of the gene from each parent to be seriously affected. Homocystinuria has several features in common with Marfan syndrome, including joint and eye changes. Symptoms Newborn infants appear healthy. Early symptoms, if present, are not obvious. Symptoms may occur as mildly delayed development or failure to thrive. Increasing visual problems may lead to diagnosis of this condition. Other symptoms include: Chest deformities (pectus carinatum, pectus excavatum) Flush across the cheeks High arches of the feet Intellectual disability Knock knees Long limbs Mental disorders Nearsightedness Spidery fingers (arachnodactyly) Tall, thin build

Whereas it is true that no operation has been profoundly affected by the advent of laparoscopy than cholecystectomy has, it is equally true that no procedure has been more instrumental in ushering in the laparoscopic age than laparoscopic cholecystectomy has. Laparoscopic cholecystectomy has rapidly become the procedure of choice for routine gallbladder removal and is currently the most commonly performed major abdominal procedure in Western countries.[1] A National Institutes of Health consensus statement in 1992 stated that laparoscopic cholecystectomy provides a safe and effective treatment for most patients with symptomatic gallstones and has become the treatment of choice for many patients.[2] This procedure has more or less ended attempts at noninvasive management of gallstones. The initial driving force behind the rapid development of laparoscopic cholecystectomy was patient demand. Prospective randomized trials were late and largely irrelevant because advantages were clear. Hence, laparoscopic cholecystectomy was introduced and gained acceptance not through organized and carefully conceived clinical trials but through acclamation. Laparoscopic cholecystectomy decreases postoperative pain, decreases the need for postoperative analgesia, shortens the hospital stay from 1 week to less than 24 hours, and returns the patient to full activity within 1 week (compared with 1 month after open cholecystectomy).[3, 4] Laparoscopic cholecystectomy also provides improved cosmesis and improved patient satisfaction as compared with open cholecystectomy. Although direct operating room and recovery room costs are higher for laparoscopic cholecystectomy, the shortened length of hospital stay leads to a net savings. More rapid return to normal activity may lead to indirect cost savings.[5] Not all such studies have demonstrated a cost savings, however. In fact, with the higher rate of cholecystectomy in the laparoscopic era, the costs in the United States of treating gallstone disease may actually have increased. Trials have shown that laparoscopic cholecystectomy patients in outpatient settings and those in inpatient settings recover equally well, indicating that a greater proportion of patients should be offered the outpatient modality

Ventricular fibrillation is a heart rhythm problem that occurs when the heart beats with rapid, erratic electrical impulses. This causes pumping chambers in your heart (the ventricles) to quiver uselessly, instead of pumping blood. Sometimes triggered by a heart attack, ventricular fibrillation causes your blood pressure to plummet, cutting off blood supply to your vital organs. Ventricular fibrillation, an emergency that requires immediate medical attention, causes the person to collapse within seconds. It's the most frequent cause of sudden cardiac death. Emergency treatment includes cardiopulmonary resuscitation (CPR) and shocks to the heart with a device called a defibrillator. Treatments for those at risk of ventricular fibrillation include medications and implantable devices that can restore a normal heart rhythm.

Carbon monoxide poisoning occurs after too much inhalation of carbon monoxide (CO). Carbon monoxide is a toxic gas, but, being colorless, odorless, tasteless, and initially non-irritating, it is very difficult for people to detect.

HYSTERECTOMY RECOVERY: ALL PROCEDURES ARE NOT CREATED EQUAL Too often, women are only given the option of an open hysterectomy for conditions like large fibroids or an enlarged uterus. Surgical techniques have evolved in the last decade, but across the United States, the number of women still having open hysterectomy procedures is unnecessarily staggering. Robotic procedures are becoming more common as hospitals invest nearly $2 million in the machine. While the robot does allow surgeons who are not necessarily trained in laparoscopic procedures to perform a more minimally invasive surgery, tools cannot replace skill. There is no added benefit to the patient and the surgery can cost on average up to $2,000 more than other laparoscopic options, and in some cases much higher.

Sperm Meets Egg: Weeks 1 to 3 of Pregnancy. Something magical is about to happen! Watch as the ovulation process occurs, and then millions of sperm swim upstream on a quest to fertilize an egg. ... The egg travels down the fallopian tube, pushed by tiny hairs and awaits the arrival or sperm.

Sickle cell anemia is an inherited form of anemia: This is a condition in which there aren't enough healthy red blood cells to carry adequate oxygen throughout your body. Normally, your red blood cells are flexible and round, moving easily through your blood vessels. In sickle cell anemia, the red blood cells become rigid and sticky and are shaped like sickles or crescent moons. These irregularly shaped cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body. There's no cure for most people with sickle cell anemia. However, treatments can relieve pain and help prevent further problems associated with sickle cell anemia.

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.

Chronic angina is a prevalent manifestation of cardiovascular disease and is most commonly due to insufficient oxygen supply from fixed epicardial lesions in the coronary arteries.

Golfer's elbow causes pain that starts on the inside bump of the elbow, the medial epicondyle. Wrist flexors are the muscles of the forearm that pull the hand forward. The wrist flexors are on the palm side of the forearm. Most of the wrist flexors attach to one main tendon on the medial epicondyle.

This video: The veins around your anus tend to stretch under pressure and may bulge or swell. Swollen veins (hemorrhoids) can develop from an increase in pressure in the lower rectum. Factors that might cause increased pressure include: Straining during bowel movements.

Nerves are the organs that make up the peripheral nervous system (PNS). They serve as information pipelines that allow the brain and spinal cord to communicate with other tissues and organs. Inside the nerves are the axon processes of sensory and motor neurons (nerve cells).

Encourage your child to drink lots of fluids to prevent dehydration. Milk and water are both fine. However, if your child refuses solids, give your child just milk, rather than water. ... Keep giving your child table foods while he has diarrhea. Diarrhea is most often spread through fecally contaminated food, hands or surfaces touched by objects or hands put into the mouth (fecal-oral route).Water contaminated by human or animal feces (e.g., swimming pools) or trips to sites with animals (e.g., farms, pet stores, petting zoos) are also possible routes of ... The best foods for your child are easily digestible foods, such as rice cereal, pasta, breads, cooked beans, mashed potatoes, cooked carrots, applesauce, and bananas. Pretzels or salty crackers can help your child replace the salt lost from diarrhea. Foods containing large amounts of sugar or fat should be avoided.

Dehydration can also be a cause of kidney stones. A common symptom is having a lower left abdominal pain, fever, nausea, groin pain and vomiting. Lower left abdominal pain can also be caused by an infection of the kidneys. It usually begins with the bladder and then reaches out to the kidneys.

Rehabilitation time for a meniscus repair is about 3 months. A meniscectomy requires less time for healing — approximately 3 to 4 weeks. Meniscus tears are extremely common knee injuries. With proper diagnosis, treatment, and rehabilitation, patients often return to their pre-injury abilities.

Endometrial cancer is a type of cancer that begins in the uterus. The uterus is the hollow, pear-shaped pelvic organ in women where fetal development occurs. Endometrial cancer begins in the layer of cells that form the lining (endometrium) of the uterus. Endometrial cancer is sometimes called uterine cancer. Other types of cancer can form in the uterus, including uterine sarcoma, but they are much less common than endometrial cancer. Endometrial cancer is often detected at an early stage because it frequently produces abnormal vaginal bleeding, which prompts women to see their doctors. If endometrial cancer is discovered early, removing the uterus surgically often cures endometrial cancer.

Three cholinesterase inhibitors are commonly prescribed: Donepezil (Aricept) is approved to treat all stages of Alzheimer's. Rivastigmine (Exelon) is approved to treat mild to moderate Alzheimer's. Galantamine (Razadyne) is approved to treat mild to moderate Alzheimer's. Currently, there is no cure for Alzheimer's. But drug and non-drug treatments may help with both cognitive and behavioral symptoms. Researchers are looking for new treatments to alter the course of the disease and improve the quality of life for people with dementia. ... Medications for Memory Loss.
