Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or cardiac arrhythmia is converted to a normal rhythm using electricity or drugs. Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle.

Most babies will move into delivery position a few weeks prior to birth, with the head moving closer to the birth canal. When this fails to happen, the baby’s buttocks and/or feet will be positioned to be delivered first. This is referred to as “breech presentation.” Breech births occur in approximately 1 out of 25 full-term births.

Intracranial pressure (ICP) is the pressure inside the skull and thus in the brain tissue and cerebrospinal fluid (CSF). ICP is measured in millimeters of mercury (mmHg) and, at rest, is normally 7–15 mmHg for a supine adult.

Frontotemporal degeneration (FTD) is a disease process that results in progressive damage to the temporal and/or frontal lobes of the brain. It causes a group of brain disorders that share many clinical features.

Acromegaly is usually caused by a noncancerous tumor. Middle-aged adults are most commonly affected. Symptoms include enlargement of the face, hands, and feet. Prompt treatment is needed to avoid serious illness. Drugs can reduce the effects of growth hormone. If needed, surgery and radiation may be used to remove tumor cells.

Pyogenic granuloma (lobular capillary hemangioma[1] ) is a relatively common benign vascular lesion of the skin and mucosa whose exact cause is unknown. Also see the Medscape Reference article Oral Pyogenic Granuloma. Pyogenic granulomas are misnamed; they are neither infectious nor granulomatous. The lesion usually occurs in children and young adults as a solitary, glistening red papule or nodule that is prone to bleeding and ulceration. Pyogenic granulomas typically evolve rapidly over a period of a few weeks, most often on the head, neck, extremities, and upper trunk. Pyogenic granuloma often arises in pregnancy (or rarely with oral contraceptive usage), particularly on the gingiva or elsewhere in the oral mucosa, and then is termed the "pregnancy tumor." Other pyogenic granuloma variants that have been well documented include the disseminated, subcutaneous, intravenous, and medication-induced (for example, retinoid, antiretroviral, and oncologic agent) subtypes. Removal of pyogenic granuloma is indicated to alleviate any bleeding, discomfort, cosmetic distress, and diagnostic uncertainty. A number of malignant tumors may clinically mimic pyogenic granuloma, making histopathologic confirmation important if the presentation is atypical. Aside from cutaneous and oral lesions, pyogenic granuloma has been reported throughout the gastrointestinal tract and upper airway, at various ocular locations, the central nervous system, the bladder, and the internal vasculature. This article discusses only cutaneous and oral involvement.

A cervical rib in humans is an extra rib which arises from the seventh cervical vertebra. Sometimes known as "neck ribs", their presence is a congenital abnormality located above the normal first rib. A cervical rib is estimated to occur in 0.2% (1 in 500 people) to 0.5% of the population.

Treatment may not be needed for an eschar if it is part of the natural healing process. However, if an eschar looks like it may have a wound infection – symptoms can include oozing fluid such as pus or blood, your clinician will likely recommend topical treatment or debridement to help control and remove the infection.

Blepharitis is an inflammation of the eyelids in which they become red, irritated and itchy and dandruff-like scales form on the eyelashes. It is a common eye disorder caused by either bacteria or a skin condition, such as dandruff of the scalp or acne rosacea. It affects people of all ages. Although uncomfortable, blepharitis is not contagious and generally does not cause any permanent damage to eyesight.

Frontotemporal dementia is the name for a range of conditions in which cells in the frontal and temporal lobes of the brain are damaged. These lobes control behaviour, emotional responses and language. This means that people will experience changes in personality and behaviour, or may struggle with language – for example, in finding the right word. Frontotemporal dementia is a less common form of dementia which is more likely to affect younger people – those under 65.
