What Causes Low Platelets?

Platelets, or thrombocytes, are described as “small, irregularly-shaped anuclear cells (i.e. cells that do not have a nucleus containing DNA), 2-3 µm in diameter which are derived from fragmentation of precursor megakaryocytes”; megakaryocytes are bone marrow cells and the platelets are able to enter the bloodstream through broken megakaryocytes caused by thrombopoietin (hormone that maintains the platelet count). Platelets, red cells and plasma largely make up the composition of human and animal...

Tay-Sach’s Disease

Tay-Sachs disease is a fatal genetic lipid storage disorder in which harmful quantities of a fatty substance called ganglioside build up in tissues and nerve cells in the brain. The disease is named after the British ophthalmologist Warren Tay who first described the red spot on the retina of the eye in 1881, and the American neurologist Bernard Sachs of Mount Sinai Hospital, New York who described the cellular changes of Tay-Sachs and noted an increased prevalence in the Eastern European Jewish...

Symptoms of Down Syndrome

Down Syndrome is a condition that occurs due to the presence of an extra 21st chromosome. It is named after the British physicist, John Langdon Down. Down Syndrome can be detected through a series of screenings and tests, performed before child birth. However, it is not possible to predict how these complications will develop, after the birth of the child. People with Down Syndrome can encounter cognitive and physical disabilities and  their problems can range from mild to severe, but having said...

Head lice are contagious and are passed from an infected person to uninfected person by direct head-to-head contact, shared combs and hairbrushes, hats and other hair and head accessories.

What Causes Macrodactyly?

Definition Macrodactyly is an uncommon birth defect in which toes or fingers are abnormally large due to overgrowth of underlying bone and soft tissue-particularly the nerves, fat and skin of the involved digit or digits. It is more commonly considered static, with the enlarged digit (finger or toe) continuing to grow at the same rate as the normal digits of the hand, but it can be progressive, with the affected digits growing faster than the rest of the hand. In the static type, the involved digits...

What Causes Circulatory Shock?

What is Circulatory Shock Circulatory shock, commonly known as just shock, is a serious, life-threatening medical condition characterized by a decrease in tissue perfusion to a point at which it is inadequate to meet cellular metabolic needs. As the blood carries oxygen and nutrients around the body, reduced flow hinders the delivery of these components to the tissues, and can stop the tissues from functioning properly. Circulatory shock should not be confused with the emotional state of shock as...

Hypothermia Treatment

Defining Hypothermia Hypothermia is a condition where a person’s core body temperature goes down far below the temperature required for normal metabolism. A human being’s body temperature is almost always constantly maintained at 36.5 to 37.5 degrees Celsius or 98 to 100 degrees Fahrenheit. This constant body temperature is maintained through thermoregulation or otherwise known as homeostasis. Understanding this condition is essential in hypothermia treatment. Causes of Hypothermia Hypothermia...
