Polymorphic Catecholergic Ventricular Tachycardia

Polymorphic Catecholergic Ventricular Tachycardia ( also known as Catecholaminergic polymorphic ventricular tachycardia (CPVT),  familial polymorphic ventricular tachycardia (FPVT) or catecholamine-induced polymorphic ventricular tachycardia), is a disorder characterized by an abnormal heart rhythm (arrhythmia). Thought to affect as many as one in ten thousand people, it is estimated to cause 15% of all unexplained sudden cardiac deaths in young people.

Polymorphous low-grade adenocarcinoma

This rare tumor occurs predominantly in an intraoral location, with the palate the most common site. It is a tumor that may mimic many benign and malignant salivary gland tumors and for many years, was probably misdiagnosed as tumors such as adenoid cystic carcinoma and mixed tumors.

Polymyositis

Polymyositis (pol-e-mi-o-SI-tis) is an uncommon disease that causes inflammation in your muscles. It's a type of connective tissue disease. The most noticeable characteristic of polymyositis is muscle weakness, especially in the muscles closest to your trunk, such as your shoulder and hip muscles. As a result, you may find it difficult to get out of chairs, climb stairs, brush your hair or work with your arms over your head. Polymyositis can occur at any age, but it mostly affects adults in their 40s and 50s. It's more common in blacks than in whites, and women have it more often than men do. Polymyositis usually develops gradually over weeks or months. Periods of remission, during which symptoms improve spontaneously, rarely occur in polymyositis. However, treatment can improve your muscle strength and function.

Polyneuritis

Polyneuritis: Widespared inflammation of nerves.

Polyneuropathy hand defect

Polyneuropathy - hand defect: A very rare syndrome characterized mainly by flexion deformity of the thumb and some fingers as well as sensory disturbance in the arms.

Polyneuropathy mental retardation acromicria prema

Polyneuropathy - mental retardation - acromicria - premature menopause: A very rare syndrome characterized mainly by premature menopause, sensory impairment, mental retardation and small, delicate facial bones.

Polyomavirus allograft nephropathy

Polyomavirus allograft nephropathy: An infection with polyomavirus that becomes symptomatic following a kidney transplant. Polyomaviruses is an infection that is often acquired during childhood but generally presents no symptoms. However, that virus may be reactivated when a patient receives immunosuppressive therapy following an organ transplant. Most adults have antibodies to the virus in their bodies. The polyomavirus family has two main subgroups: BK virus and JC virus.

Polyomavirus Infections

Polyomavirus Infections: A viral infection that is often acquired during childhood but generally presents no symptoms. However, that virus may be reactivated when a patient receives immunosuppressive therapy following an organ transplant. Most adults have antibodies to the virus in their bodies.

Polyostotic osteolytic dysplasia- hereditary expansile

Polyostotic osteolytic dysplasia, hereditary expansile: A very rare syndrome characterized by severe bone pain and deformity as well jaw and ear abnormalities. Deafness usually starts in the first decade. Bone symptoms such as pain usually start in the second decade.

Polyposis skin pigmentation alopecia fingernail changes

Polyposis skin pigmentation alopecia fingernail changes: Another name for Cronkhite-Canada disease (or close medical condition association). Polyposis skin pigmentation alopecia fingernail changes (medical condition): A rare condition characterized primarily by polyps in the digestive tract, hair loss and nail problems.

Polysyndactyly type Haas

Polysyndactyly type Haas: A malformation where all the fingers are webbed and there is an extra digit. The webbing did not involve any bone fusion. The feet may have variable degrees of webbing and an extra toe may be present.

Pompe disease

Pompe disease, also known as Glycogen storage disease type 2 is an inherited metabolic disorder caused by an inborn lack of the enzyme acid alpha-glucosidase (also known as acid maltase), which is necessary to break down glycogen, a substance that is a source of energy for the body. This enzyme deficiency causes excess amounts of glycogen to accumulate in the lysosomes, which are structures within cells that break down waste products within the cell. This accumulation of glycogen in certain tissues, especially muscles, impairs their ability to function normally. Glycogen storage disease type 2 is a single disease continuum with variable rates of disease progression.
