The heart, blood vessels, and blood are the parts that make up the circulatory system, which is defined as a closed system of blood vessels for the transport of gasses and nutrients. The heart is the key organ in the circulatory system. As a hollow, muscular pump, its main function is to propel blood throughout the body.

A visual prosthesis, often referred to as a bionic eye, is an experimental visual device intended to restore functional vision in those suffering from partial or total blindness. In 1983 Joao Lobo Antunes, a Portuguese doctor, implanted a bionic eye in a person born blind.

Microscopic polyangiitis (MPA) is vasculitis of small vessels. It was initially considered as a microscopic form of polyarteritis nodosa (PAN). In 1990, the American College of Rheumatology developed classification criteria for several types of systemic vasculitis but did not distinguish between polyarteritis nodosa and microscopic polyarteritis nodosa. [1] In 1994, a group of experts held an international consensus conference in Chapel Hill, North Carolina, to attempt to redefine the classification of small vessel vasculitides. [2, 3]

Blind loop syndrome (BLS), commonly referred to in the literature as small intestinal bacterial overgrowth (SIBO) or bacterial overgrowth syndrome (BOS), is a state that occurs when the normal bacterial flora of the small intestine proliferates to numbers that cause significant derangement to the normal physiological ...

Alcohol not broken down by the liver goes to the rest of the body, including the brain. Alcohol can affect parts of the brain that control movement, speech, judgment, and memory. These effects lead to the familiar signs of drunkenness: difficulty walking, slurred speech, memory lapses, and impulsive behavior.

An epidural abscess is a collection of pus (infected material) between the outer covering of the brain and spinal cord and the bones of the skull or spine. The abscess causes swelling in the area. Spinal cord abscess (SCA) is a rare condition capable of causing permanent damage to the spinal cord. Abscesses are caused when injured tissue becomes infected. The body's immune system sends white blood cells to help fight off the infection. They begin to fill the damaged tissue, causing pus to build up.

In developing countries, domestic animals (eg, dogs) are common sources of infection. In the United States, bats and wild animals (eg, raccoons) are the most common reservoirs of infection. The acquisition of rabies from bats can occur from an unrecognized bite or a scratch, and possibly by inhalation of aerosolized viral particles. Bats are found in all states except Hawaii, and spelunking (cave exploration) is a risk factor for rabies acquisition from bats.

PIP breast implants exchanged with Nagor 4th generation silicone implants by plastic surgeon Adrian Richards at Aurora clinics in Milton Keynes. During PIP removal procedure, the implants appear in good shape, but as with majority of PIP implants, evidence of silicone gel bleed is found inside the patient's breast pocket, as well as free silicone which caused pain and discomfort to this patient.

When the colon and rectum are removed (due to ulcerative colitis or familial adenomatous polyposis), another reservoir must be created for bowel contents (stool) to exit the body. Surgically creating a “J” shaped reservoir (called a J-pouch) is an option for selected patients to store and pass stool.

The etiology of BOO is diverse and definitely gender specific. Often anatomic causes induce functional abnormality that remains somewhat unique for each individual, regardless of sex. A full appreciation of the possible etiologies of obstruction is necessary in order to identify overt and more subtle scenarios. In women, iatrogenic causes of obstruction are the most common. Other entities account for far fewer of the cases. The obstruction evaluation in women is somewhat more diverse in terms of modalities used, with no single grouping of techniques that are generally apropos. Individualized evaluation remains a tenet of analysis, and urodynamic criteria used to diagnose BOO in women continue to evolve.
