Methicillin-resistant Staphylococcus aureus (Wikipedia article) - Methicillin-resistant Staphylococcus aureus (MRSA), also known as oxacillin-resistant Staphylococcus aureus (ORSA), multiple-resistant Staphylococcus aureus, CA-MRSA (community-acquired MRSA) and HA-MRSA (hospital-acquired MRSA), is a biological agent responsible for difficult-to-treat infections in humans. It is a variation of Staphylococcus aureus, a common bacterium, which has evolved the ability to survive treatment with beta-lactam antibiotics, including penicillin and methicillin. The organism is especially troublesome in hospital-acquired (nosocomial) infections. In hospitals, patients may be found who have open wounds and weakened immune systems and who thus are greatly at risk for infection. Negligent hospital staff are apt to transfer bacterial colonies from patient to patient on their unwashed hands.

The program also disseminates its findings and advocates for older people, providing an optimistic and enabling view of aging.
NINDS Shingles Information Page - Shingles (herpes zoster) are an outbreak of rash or blisters on the skin that is caused by the same virus that causes chicken pox - the varicella-zoster virus. The first sign of shingles is often burning or tingling pain, or sometimes numbness, in or under the skin. You may also feel ill with fever, chills, headache, or upset stomach. After several days, a rash of small fluid-filled blisters, reminiscent of chickenpox, appears on reddened skin. The pain associated with shingles can be intense and is often described as "unrelenting." Anyone who has had chickenpox is at risk for shingles.
Non-Ionizing Radiation: Extremely Low Frequency Fields - Extremely low frequency (ELF) fields includes alternating current (AC) fields and other electromagnetic, non-ionizing radiation from 1 Hz to 300 Hz. ELF fields at 60 Hz are produced by power lines, electrical wiring, and electrical equipment. Current research has focused on potential health effects of magnetic fields because some epidemiological studies have suggested increased cancer risk associated with estimates of magnetic field exposure. Exposure to EMFs depends on the strength of the ELF fields at the source, the distance from the source, and the duration of exposure.
North American Menopause Society (NAMS) - Leading nonprofit scientific organization devoted to promoting understanding of menopause, and thereby improving the health of women through midlife and beyond.
Nosebleed - The nose contains many small blood vessels that bleed easily. Air moving through the nose can dry and irritate the membranes lining the inside of the nose, forming crusts. These crusts bleed when irritated by rubbing, picking, or blowing the nose. The lining of the nose is more likely to become dry and irritated from low humidity, allergies, colds, or sinusitis. Thus, nosebleeds occur more frequently in the winter when viruses are common and heated indoor air dries out the nostrils. A deviated septum, foreign object in the nose, or other nasal blockage can also cause a nosebleed. Home care: Sit down and gently squeeze the soft portion of the nose between your thumb and finger (so that the nostrils are closed) for a full 10 minutes. Lean forward to avoid swallowing the blood and breathe through your mouth. Wait at least 10 minutes before checking if the bleeding has stopped. Many nosebleeds can be controlled in this way if enough time is allowed for the bleeding to stop. It may help to apply cold compresses or ice across the bridge of the nose. Do not pack the inside of the nose with gauze. Lying down with a nosebleed is not recommended. You should avoid sniffing or blowing your nose for several hours after a nosebleed. If bleeding persists, a nasal spray decongestant (Afrin, NeoSynephrine) can sometimes be used to close off small vessels and control bleeding.

Prions (.pdf, 56 pp.) - Text of the Nobel Lecture presented by Stanley B. Prusiner on 08 Dec 97. Prusiner was awarded the Nobel Prize in Physiology or Medicine for 1997 for his discovery of "Prions - a new biological principle of infection ". Prions exist normally as innocuous cellular proteins, however, prions possess an innate capacity to convert their structures into highly stabile conformations that ultimately result in the formation of harmful particles, the causative agents of several deadly brain diseases of the dementia type in humans and animals. Prion diseases may be inherited, laterally transmitted, or occur spontaneously. Regions within diseased brains have a characteristic porous and spongy appearance, evidence of extensive nerve cell death, and affected individuals exhibit neurological symptoms including impaired muscle control, loss of mental acuity, memory loss and insomnia.

Scabies - A transmissible ectoparasite skin infection characterized by superficial burrows, intense pruritus (itching) and secondary infection. Scabies is caused by the mite Sarcoptes scabiei, variety hominis, as shown by the Italian biologist Diacinto Cestoni in the 18th century. It produces intense, itchy skin rashes when the impregnated female tunnels into the stratum corneum of the skin and deposits eggs in the burrow. The larvae, which hatch in 3-10 days, move about on the skin, molt into a "nymphal" stage, and then mature into adult mites. The adult mites live 3-4 weeks in the host's skin.
Shingles: An Unwelcome Encore - In Italy, shingles also is called St. Anthony's fire, a fitting name for a disease that has bedeviled saints and sinners throughout the ages. Caused by the same varicella-zoster virus that causes chickenpox, shingles (also called herpes zoster) most commonly occurs in older people. Treatment was once limited to wet compresses and aspirin. Today's treatments provide a variety of ways to shorten the duration of a shingles outbreak and to control the associated pain. Sometimes, however, shingles leads to a chronic painful condition called post-herpetic neuralgia (PHN) that can be difficult to treat.
Shoulder Impingement - Impingement is one of the most common causes of pain in the adult shoulder. It results from pressure on the rotator cuff from part of the shoulder blade (scapula) as the arm is lifted.

Also see General Information About Swine Flu and Human Swine Influenza Investigation.
Thoracic Outlet Syndrome (TOS) - TOS consists of a group of distinct disorders that affect the nerves in the brachial plexus (nerves that pass into the arms from the neck) and various nerves and blood vessels between the base of the neck and axilla (armpit). For the most part, these disorders have very little in common except the site of occurrence. The disorders are complex, somewhat confusing, and poorly defined, each with various signs and symptoms of the upper limb.
Trigger Finger - A condition in which one of your fingers or your thumb catches in a bent position. Your finger or thumb may straighten with a snap - like a trigger being pulled and released. If trigger finger is severe, your finger may become locked in a bent position. Often painful, trigger finger is caused by a narrowing of the sheath that surrounds the tendon in the affected finger. People whose work or hobbies require repetitive gripping actions are more susceptible. Trigger finger is also more common in women than in men, and in anyone with diabetes.

Reported Viremic Blood Donors (PVD) - A PVD is a person who was asymptomatic at the time of donating blood (people with symptoms are deferred from donating) through a blood collection agency, but whose blood tested positive in preliminary tests when screened for the presence of West Nile virus. PVDs are followed up by the blood agency to verify their infection with additional tests. Some PVDs do go on to develop symptoms after donation, at which point they would be included in the count of human disease cases by their state.

Zika Virus [CDC] - The Zika virus is spread to people through mosquito bites. The most common symptoms of Zika virus disease are fever, rash, joint pain, and conjunctivitis (red eyes). The illness is usually mild with symptoms lasting from several days to a week. Severe disease requiring hospitalization is uncommon. In May 2015, the Pan American Health Organization (PAHO) issued an alert regarding the first confirmed Zika virus infection in Brazil. The outbreak in Brazil led to reports of Guillain-Barre syndrome and pregnant women giving birth to babies with birth defects and poor pregnancy outcomes. In response, CDC has issued a travel alert (Level 2-Practice Enhanced Precautions) for people traveling to regions and certain countries where Zika virus transmission is ongoing.
