A medical procedure is a course of action intended to achieve a result in the delivery of healthcare. A medical procedure with the intention of determining, measuring, or diagnosing a patient condition or parameter is also called a medical test. Other common kinds of procedures are therapeutic (i.e., intended to treat, cure, or restore function or structure), such as surgical and physical rehabilitation procedures. Definition
"An activity directed at or performed on an individual with the object of improving health, treating disease or injury, or making a diagnosis." "The act or conduct of diagnosis, treatment, or operation." "A series of steps by which a desired result is accomplished." "The sequence of steps to be followed in establishing some course of action."
Hereditary pyropoikilocytosis (HPP) is an autosomal recessive form of hemolytic anemia characterized by an abnormal sensitivity of red blood cells to heat and erythrocyte morphology similar to that seen in thermal burns or from prolonged exposure of a healthy patients blood sample to high ambient temperatures. Patients with HPP tend to experience severe hemolysis and anemia in infancy that gradually improves, evolving toward typical elliptocytosis later in life. However, the hemolysis can lead to rapid sequestration and destruction of red cells. Splenectomy is curative when this occurs. HPP has been associated with a defect of the erythrocyte membrane protein spectrin and with spectrin deficiency. It was characterized in 1975. It is considered a severe form of hereditary elliptocytosis. Causes
Mutations of the alphaspectrin gene causes this disease. HPP can be considered as a subset of hereditary elliptocytosis. Diagnosis
Genetic testing for the presence of mutations in protein molecules is considered to be a confirmatory testing technique. It is important to know the risks regarding the transmission and dangers of HPP. Treatment
Splenectomy is a possible treatment
