All You Need to Know About Nephritis

To understand kidney problems such as nephritis, it's helpful to start with some background on what the kidneys are, and what they do.

The kidneys are two bean-shaped, fist-sized organs found just under the ribs on the left and right sides of the spine. They remove impurities and extra water from the blood, filtering 120-150 quarts of blood a day, according to the National Institute of Diabetes and Digestive and Kidney Diseases.

Each kidney consists of thousands of structures called nephrons, where the actual blood filtering takes place. In the nephron, a two-step cleaning process separates what the body needs to keep from what it can get rid of.

A filter called the glomerulus catches blood cells and protein, sending water and waste to a second filter, called a tubule. The tubule captures minerals. After that, what remains leaves the body as urine.

Bacterial Pneumonia - Get the Facts

Bacterial pneumonia is an inflammation of the lungs due to some form of bacteria. There are different types of bacteria that may lead to the infection.

The lungs are made up of different sections or lobes. There are three lobes on the right and two on the left. Bacterial pneumonia can affect both lungs, one lung, or even just one section of a lung.

The lobes of the lungs are made up of small air sacs called alveoli. Normally, the air sacs fill with air. Oxygen is inhaled and carbon dioxide in exhaled.

When a person develops pneumonia, the air sacs become inflamed, which can cause them to fill with fluid. If the air sacs are filled with fluid instead of air, it can make breathing difficult. In some cases, the lungs may not get enough oxygen.

Bacteria that cause pneumonia are spread through coughing. Doctors will carry out a chest X-ray to

assess fluid buildup in the lungs. An annual flu vaccine can help prevent pneumonia.

Test That Differentiates Between Bacterial, Viral Infections in Development

An international team of scientists - led by researchers at Imperial College London - has discovered two genes that are switched on when a child has a bacterial infection. This revelation could allow the team to develop a rapid test for doctors' surgeries and hospitals to identify infections such as meningitis, and assist with the growing threat of antibiotic resistance.

The study, published in JAMA, found that the two genes, called IFI44L and FAM89A, only shifted to an "on" state when a bacterial infection was present. This knowledge could enable doctors to distinguish between bacterial and viral infections, and identify early cases of severe infections that could be deadly.

While viral infections are more common than bacterial infections, bacterial infections are often more serious.

Meningitis, septicemia, and pneumonia all occur as a result of a bacterial infection. Differentiating between these potentially life-threatening conditions and viruses can allow health providers to provide quicker, more accurate treatments.

HIV: Newly Discovered Component Could Lead to More Effective Drugs

Scientists from the Medical Research Council Laboratory of Molecular Biology in Cambridge and University College London - both in the United Kingdom - have uncovered key components of HIV, which they believe could lead to new approaches for drugs to fight the infection.

HIV weakens a person's immune system by destroying important cells that fight disease and infection. Only certain body fluids - blood, semen, rectal fluids, vaginal fluids, and breast milk - from a person who has HIV can transmit HIV.

According to the Centers for Disease Control and Prevention (CDC), an estimated 1.2 million people are living with HIV in the United States. Although there is no cure for HIV infection, improved treatments allow people living with HIV to slow the virus' progression and stay relatively healthy for several years.

HIV is a part of a subtype of viruses called retroviruses, which means that the virus is composed of RNA - instead of normal DNA - and has the unique property of transcribing RNA into DNA after entering a cell.

Appendicitis: Warning Signs and Early Symptoms

Appendicitis is a condition in which the appendix becomes inflamed. Its symptoms can become very uncomfortable, painful, and potentially life-threatening if left untreated.

Sudden appendicitis is the most common cause of acute abdominal pain requiring surgery in the United States. Additionally, more than 5 percent of the population develops appendicitis at some point.

Though it most commonly occurs between the ages of 10 and 30, appendicitis can develop at any age.

Antibiotic Resistance Raising the Specter of 'Untreatable Gonorrhea'

A new federal health surveillance study says gonorrhea is becoming resistant to azithromycin - one of the duo of antibiotics recommended for treating the sexually transmitted disease in the United States.

The study, from the Centers for Disease Control and Prevention (CDC), is published in the agency's Morbidity and Mortality Weekly Report (MMWR).

Gonorrhea is a sexually transmitted disease (STD) caused by a bacterium called Neisseria gonorrhoeae that infects the genitals, rectum, and throat.

Gonorrhea occurs in both men and women, and is one of the most common STDs in the U.S. It is especially common among young people of 15-24 years of age.

H. Pylori: Know the Facts

Helicobacter pylori, commonly called H. pylori, is a type of bacteria that can infect the stomach and small bowel. It was discovered in 1982 by two Australian researchers who found that it causes peptic ulcer disease.

Peptic ulcers are open sores in the lining of the stomach or the upper part of the small intestine. Peptic ulcers are often called "ulcers" or "stomach ulcers."

For years, medical experts believed that peptic ulcers were caused by stress or certain foods. After the discovery of H. pylori, however, this belief was put to rest. A study in Digestive and Liver Disease suggests that 60 to nearly 100 percent of peptic ulcers are associated with H. pylori.

Viral Hepatitis Has Become a Leading Global Killer

Compared with most other communicable diseases, hepatitis has risen in global importance since the 1990s. It is now a leading cause of death and disability worldwide and kills at least as many people as tuberculosis, HIV/AIDS, or malaria.

This is the main finding of an international study - led by Imperial College London in the United Kingdom and the University of Washington in Seattle - published in The Lancet.

The study - which analyzes data from 1990-2013 on 183 countries - is timely, as the World Health Organization (WHO) launch a major new effort to tackle viral hepatitis.

The findings should prove of "crucial importance to global health policy," note the authors.

Measles: Causes, Symptoms and Treatments

Measles, also known as Rubeola or morbilli, is a highly infectious illness caused by a virus - a viral infection caused by the rubeola virus.

Measles is an endemic disease; meaning it is continually present in a community and many people develop resistance. If measles enters an area where the people have never been exposed the result can be devastating.

A measles outbreak in 1592 in the island of Cuba killed approximately two-thirds of the native population who had previously survived smallpox. A couple of years later half the indigenous population of Honduras died.

How a single blood test could identify your entire viral infection history

Researchers have created what they say is a "one-stop shop" for diagnosing infections - a test that can determine an individual's complete viral history just by scanning a single drop of blood.

The test, called VirScan, was created by Stephen Elledge and colleagues from the Howard Hughes Medical Institute (HHMI).

"We've developed a screening methodology to basically look back in time in people's [blood] sera and see what viruses they have experienced," explains Elledge. "Instead of testing for one individual virus at a time, which is labor intensive, we can assay all of these at once. It's one-stop shopping."

Novel blood test could diagnose diseases with no known antigens

It may one day be possible to identify cancer, autoimmune diseases, and a wealth of other conditions from a single drop of blood, after a team from the University of Pittsburgh reveals the creation of a test that holds promise for such a feat.

In the Journal of Immunological Methods, the researchers explain how they developed a test that may be able to identify diseases for which there are no known microbial causes.

Antigens are substances - such as bacteria, viruses, or chemicals - that induce an immune response in the body, causing the immune system to produce antibodies that target and destroy these foreign invaders.
