A head injury is any trauma that leads to injury of the scalp, skull, or brain. The injuries can range from a minor bump on the skull to serious brain injury. Head injury is classified as either closed or open (penetrating. A closed head injury means you received a hard blow to the head from striking an object; An open, or penetrating, head injury means you were hit with an object that broke the skull and entered the brain. This usually happens when you move at high speed, such as going through the windshield during a car accident. It can also happen from a gunshot to the head. There are several types of brain injuries. Two common types of head injuries are: Concussion, the most common type of traumatic brain injury; Contusion, which is a bruise on the brain. See also: Subarachnoid hemorrhage; Subdural hematoma.

Hemochromatosis is an inherited blood disorder that causes the body to retain excessive amounts of iron. This iron overload can lead to serious health consequences, most notably cirrhosis of the liver.

Iron is a mineral that the human body uses to produce the red blood cells (hemoglobin) that carry oxygen throughout the body. It is also stored in myoglobin, an oxygen-carrying protein in the muscles that fuels cell growth.
|

Hemochromatosis is an inherited blood disorder that causes the body to retain excessive amounts of iron. This iron overload can lead to serious health consequences, most notably cirrhosis of the liver.
|
|
Iron tests consist of four assays performed on serum or plasma to aid in the diagnosis and treatment of iron deficiency or iron overload. These tests are serum iron, total iron binding capacity (TIBC), serum ferritin, and serum transferrin.
|
|
Iron tests are a group of blood tests that are done to evaluate the iron level in blood serum, the body ' s capacity to absorb iron, and the amount of iron actually stored in the body. Iron is an essential trace element; it is necessary for the formation of red blood cells and certain enzymes.

Histiocytosis is a general name for a group of syndromes that involve an abnormal increase in the number of immune cells called histiocytes. There are three major classes of histiocytoses: Langerhans cell histiocytosis, which is also called histiocytosis X; Malignant histiocytosis syndrome (now known as T-cell lymphoma; Non-Langerhans cell histiocytosis (also known as hemophagocytic syndrome. This article focuses only on Langerhans cell histiocytosis (histiocytosis X.
|
|
Histiocytosis X is a generic term that refers to an increase in the number of histiocytes, a type of white blood cell, that act as scavengers to remove foreign material from the blood and tissues. Since recent research demonstrated Langerhans cell involvement as well as histiocytes, this led to a proposal that the term Langerhans Cell Histiocytosis (LCH) be used in place of histiocytosis X.

Radiotherapy is the use of high-energy penetrating radiation (x rays, gamma rays, proton rays, and neutron rays) to kill cancer cells. Purpose The primary purpose of radiotherapy is to eliminate or shrink localized cancers.
|
|
Electromagnetic waves of extremely short wavelength (X-rays and gamma rays) and accelerated atomic particles (such as electrons, protons, neutrons, and alpha particles) deposit enough localized energy in an absorbing medium to dislodge electrons from atoms with which they interact and to disrupt chemical bonds. The loss of electrons creates particles known as " ions, " and these types of radiation are termed " ionizing radiation.
|
|
Nonionizing radiation, in contrast to ionizing radiation, is electromagnetic radiation that does not have sufficient energy to remove electrons from an atom or molecules to form an ion (or charged particle) during a collision. Instead, it imparts energy to other particles, which typically results in heating.
|
|
Radiation and radioisotopes are extensively used medications to allow physicians to image internal structures and processes in vivo (in the living body) with a minimum of invasion to the patient. Higher doses of radiation are also used as means to kill cancerous cells.
|
|
The principal adverse health effects of sunlight are caused by the ultraviolet and visible radiation it contains. Ultraviolet radiation (UVR) comprises a spectrum of electromagnetic waves of different wavelengths, subdivided for convenience into three bands, which are measured in nanometers (nm):(1) UVA ( " black light " ), 315 to 400 nm; (2) UVB, 280 to 315 nm; and (3) UVC (which is germicidal), 200 to 280 nm.

|
 |
A stroke is an interruption of the blood supply to any part of the brain. A stroke is sometimes called a "brain attack."
|
|
Symptoms of a StrokeDuring a stroke, blood stops flowing to part of the brain. This can damage areas in the brain that control the rest of the body.
|
|
A stroke is an interruption of blood circulation to the brain causing a neurologic deficit reflecting the area of the brain affected. Stroke can be ischemic or hemorrhagic. 1 Ischemic stroke is most prevalent.

Stroke is an increasing public health concern throughout the world as the leading cause of long-term disability. There is estimated to be over 3.5 million survivors of stroke in the United States.

There are various clinical and pathological subtypes of stroke, and identification of the subtype is necessary for correct management. Investigations Imaging Brain imaging should be performed within the first 48 hours of the onset of stroke (see below), to determine whether the stroke is haemorrhagic or ischaemic and to exclude other causes (e.g. tumour).

Stroke, or cerebrovascular accident (CVA), is the third leading cause of death (after heart disease and cancer) in the United States and the industrialized countries of the world. The term " stroke, " which comes from subjects being suddenly " struck down " with neurological deficits, is commonly used by both professional and lay groups.

 |
Cerebrovascular accident (CVA) is the medical term for what is commonly termed a stroke. It refers to the injury to the brain that occurs when flow of blood to brain tissue is interrupted by a clogged or ruptured artery, causing brain tissue to die because of lack of nutrients and oxygen.
|
|
A ministroke, or transient ischemic attack (TIA), is a brief episode of stroke symptoms caused by temporary interruption of blood flow to the brain. Most people suffer TIAs without realizing it.

More women than men are victims of stroke, and the consequences for survivors are more serious in women. Medication to dissolve blood clots is available, but must be administered within the first three hours after a stroke to be most effective.
|
 |
A stroke, also called a cerebral infarction, is a life-threatening condition marked by a sudden disruption in the blood supply to the brain. A disruption in the blood supply to the brain starves the brain of oxygen-rich blood and causes the nerve cells in that area to become damaged and die within minutes.

Strokes often result in long-term health problems, and sometimes death. But there are steps you can take to help prevent them.
