The timing of the nausea or vomiting can indicate the cause. When appearing shortly after a meal, nausea or vomiting may be caused by food poisoning, gastritis (inflammation of the stomach lining), an ulcer, or bulimia. Nausea or vomiting one to eight hours after a meal may also indicate food poisoning.

The baby suffered from ectopia cordis, a rare condition where a baby's heart is located either partially or totally outside the chest. Only 8 out of 1 million babies are born with the condition, and 90 percent of those babies are either stillborn or die within the first three days of life.

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.

Orchitis (or-KIE-tis) is an inflammation of one or both testicles. It is usually caused by a bacterial infection or by the mumps virus. Bacterial orchitis can be caused by sexually transmitted infections (STIs), particularly gonorrhea or chlamydia. Bacterial orchitis often results from epididymitis, an inflammation of the coiled tube (epididymis) at the back of the testicle that stores and carries sperm. In that case, it's called epididymo-orchitis. Orchitis causes pain and can affect fertility. Medication can treat the causes of bacterial orchitis and can ease some signs and symptoms of viral orchitis. But it may take several weeks for scrotal tenderness to disappear.

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.

There are four major blood groups determined by the presence or absence of two antigens – A and B – on the surface of red blood cells: Group A – has only the A antigen on red cells (and B antibody in the plasma) Group B – has only the B antigen on red cells (and A antibody in the plasma) Group AB – has both A and B antigens on red cells (but neither A nor B antibody in the plasma) Group O – has neither A nor B antigens on red cells (but both A and B antibody are in the plasma)

Acute intermittent porphyria (AIP) is a rare autosomal dominant metabolic disorder affecting the production of heme, the oxygen-binding prosthetic group of hemoglobin. It is characterized by a deficiency of the enzyme porphobilinogen deaminase.

Hepatitis B is a liver infection caused by the Hepatitis B virus (HBV). Hepatitis B is transmitted when blood, semen, or another body fluid from a person infected with the Hepatitis B virus enters the body of someone who is not infected. This can happen through sexual contact; sharing needles, syringes, or other drug-injection equipment; or from mother to baby at birth. For some people, hepatitis B is an acute, or short-term, illness but for others, it can become a long-term, chronic infection. Risk for chronic infection is related to age at infection: approximately 90% of infected infants become chronically infected, compared with 2%–6% of adults. Chronic Hepatitis B can lead to serious health issues, like cirrhosis or liver cancer. The best way to prevent Hepatitis B is by getting vaccinated.

There's a small area called the Grafenberg spot, or G-spot, inside the vagina. It's located about an inch or so inside the vaginal opening on the upper vaginal wall — closest to the bellybutton. The G-spot is sexually sensitive and swells slightly during arousal and feels raised or bumpy

The most common symptoms of infection from animal bites are redness, pain, swelling, and inflammation at the site of the bite. You should seek immediate medical treatment if any of these symptoms continue for more than 24 hours. Other symptoms of infection include: pus or fluid oozing from the wound

The complex circuitry interconnecting different areas in the brain, known collectively as white matter, is composed of millions of axons organized into fascicles and bundles. Upon macroscopic examination of sections of the brain, it is difficult to discern the orientation of the fibers. The same is true for conventional imaging modalities. However, recent advancements in magnetic resonance imaging (MRI) make such task possible in a live subject. By sensitizing an otherwise typical MRI sequence to the diffusion of water molecules it is possible to measure their diffusion coefficient in a given direction1. Normally, the axonal membrane and myelin sheaths pose barriers to the movement of water molecules and, thus, they diffuse preferentially along the axon2. Therefore, the direction of white matter bundles can be elucidated by determining the principal diffusivity of water. The three-dimensional representation of the diffusion coefficient can be given by a tensor and its mathematical decomposition provides the direction of the tracts3; this MRI technique is known as diffusion tensor imaging (DTI). By connecting the information acquired with DTI, three-dimensional depictions of white matter fascicles are obtained4. The virtual dissection of white matter bundles is rapidly becoming a valuable tool in clinical research.

Our journey begins with a transverse section of tightly packed axons as seen through light microscopy. Although represented as a two-dimensional "slice", we see that these axons in fact resemble tubes. A simulation of water molecules diffusing randomly inside the axons demonstrates how the membranes and myelin hinder their movement across them and shows the preferred diffusion direction --along the axons. The tracts depicted through DTI slowly blend in and we ride along with them. As we zoom out even more, we realize that it is a portion of the corpus callosum connecting the two sides of the brain we were traveling on and the great difference in relative scale of the individual axons becomes evident. The surface of the brain is then shown, as well as the rest of the white matter bundles--a big, apparently chaotic tangle of wires. Finally, the skin covers the brain.

With the exception of the simulated water molecules, all the data presented in the animation is obtained through microscopy and MRI. Computer algorithms for the extraction of the cerebral structures and a custom-built graphics engine make our journey through the brain's anatomy possible in a living person.

A neuron, also known as a neurone (British spelling) and nerve cell, is an electrically excitable cell that receives, processes, and transmits information through electrical and chemical signals. These signals between neurons occur via specialized connections called synapses.
