Cryptosporidium was first pinpointed as a cause of gastrointestinal disease in 1976, and was found in the 1980s to be a common cause of diarrhea in people infected with HIV. Cryptosporidium infection (cryptosporidiosis) is a gastrointestinal disease whose primary symptom is diarrhea. The illness begins when a tiny one-celled parasite enters your body and travels to your small intestine. Cryptosporidium, which means “hidden spore,” then begins its life cycle inside your body — burrowing into the walls of your intestines and then later being shed in your feces. In most healthy people, cryptosporidium infection produces a bout of watery diarrhea and resolves within a week or two. For people with a compromised immune system, it can become life-threatening without proper treatment.
Hepatitis A virus is one of six currently identified strains of viral hepatitis — the others are B, C, D, E and G. The strains differ in severity and in the way they spread. Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus. Although not usually as serious as other types of viral hepatitis, hepatitis A causes inflammation that affects your liver’s ability to function.
Iritis is a type of uveitis — inflammation of the middle layer of the eye (uvea) — that affects your eye’s iris. The iris is the colored ring of tissue surrounding your pupil, which lies just behind the transparent cornea. Muscles controlling the iris change the size of the pupil to adjust to light conditions. Prolonged inflammation can lead to adhesions of the iris, causing your pupil to become smaller or irregularly shaped and predisposing you to glaucoma. Continue reading Iritis
Osteomyelitis is the medical term for an infection in a bone.
Infections can reach a bone by traveling through your bloodstream or spreading from nearby tissue. Infections can also begin in the bone itself if trauma exposes your bone to germs. Bone infections commonly affect the long bones of your body, such as your leg bones and upper arm bone, as well as your spine and pelvis.
Osteomyelitis occurs more often in men than in women. People of any age can develop osteomyelitis, though the acute form tends to be more common in children, and people older than 50 are more likely to have the spinal form of the infection.
Osteomyelitis often occurs in children as an acute condition.
Once considered incurable, osteomyelitis can be successfully treated today. Still, osteomyelitis is a serious condition, requiring aggressive treatment to prevent spread of your infection and to save the affected bone.
The peritoneum is a silk-like membrane that lines your inner abdominal wall and covers the organs within your abdomen. Peritonitis is a bacterial or fungal infection of this lining. The infection may come from fluid buildup within the peritoneum, from another infection, inflammation or injury within your body, or it may be a complication of peritoneal dialysis.
If peritonitis is left untreated, the infection can extend beyond your peritoneum. Bacteria from peritonitis may infect your bloodstream (bacteremia) and once there, cause the infection to spread throughout your body (sepsis). Sepsis is a rapidly progressing, life-threatening condition that can cause shock and organ failure.
