What are causes and symptoms of petechiae? | Reference.com

Full Answer

Petechiae result from capillaries bursting and bleeding into the skin, states Mayo Clinic. They often occur in a cluster, giving the appearance of a rash. Petechiae maintain their color when pressed, and they are flat to the touch. Resulting from a variety of conditions ranging from mild to serious, petechiae can sometimes form on the eyelids and inner surfaces of the mouth. Prolonged straining from coughing, crying, vomiting, weightlifting or giving birth often causes petechiae on the chest, neck or face.

What are some common causes of petechiae? | Reference.com

Quick Answer

Some common causes of petechiae include prolonged straining when crying, coughing or vomiting; certain medications; injuries; and infectious diseases such as meningococcemia, scarlet fever and strep throat, as listed by Mayo Clinic. Other causes of petechiae include medical conditions such as leukaemia, vasculitis and vitamin K deficiency.

Nursing Central | Adrenal Insufficiency (Addison's Disease)

Primary adrenal insufficiency is caused by the destruction of the adrenal gland. While the disorder is not common, the most typical causes are tuberculosis (TB) or fungal infection, other diseases infiltrating the adrenal glands, and hemorrhage. The most frequent cause is idiopathic atrophy, which is probably autoimmune in origin. Secondary adrenal insufficiency results from hypopituitarism due to hypothalamic-pituitary disease or suppression of the hypothalamic-pituitary axis by steroid therapy.

What Strenuous Exercises Cause Broken Blood Vessels on the Face?

Stress Cause Petechiae

Engaging in exercise is one of the most important things you can do to care for your health and well-being. It's one of the few methods humans have for controlling their physical appearance, as well. Sometimes, however, exercising too intensely can lead to broken blood vessels on the face. While most often this is a harmless byproduct of...

Comparative distribution of petechial haemorrhages as a function of aircraft cockpit geometry.

Comparative distribution of petechial haemorrhages as a function of aircraft cockpit geometry.

Whinnery JE.

One of the stresses to which aircrew are subjected in a modern highly manoeuvrable military aircraft is produced by high-speed turns; the resultant elevated G forces may cause petechial haemorrhages, particularly in the lower limbs. Since an aeroplane is an inconvenient laboratory, the mechanisms responsible for these haemorrhages are best investigated by elevated G forces produced in a human centrifuge on the ground, where a similar stress produces the same kind of haemorrhage. Such physical stimuli are in effect a modification of the normal terrestrial gravitational force (a force which under normal conditions is assumed to be +1 G) acting in a + Gz (head to foot) direction. The distribution of petechial haemorrhages is determined by a number of factors, including cockpit configuration. Differences in the distribution of petechial haemorrhages in the F-15 and F-16 aircraft (12 degrees tilt-back seat and 30 degrees tilt-back seat with elevation of the heel, respectively) lend an insight into those body areas where there is inadequate protection. The phenomenon usually begins to develop in healthy individuals at approximately +5 Gz (head to foot), with virtually everyone having petechial haemorrhages at +9 Gz. The kinetics of +Gz -induced petechiasis is interesting, because individuals develop an acclimatized resistance to these formations, whose exact aetiology is unknown; whether or not the petechiae are due to rupture of susceptible capillaries or to diapedesis is also unknown. Stasis and pooling of blood in the lower limbs play a specific role in the petechial formation; it is not only the +Gz stress, but also the protective equipment and techniques which determine the extent and magnitude of the petechiasis.(ABSTRACT TRUNCATED AT 250 WORDS)

Vaccine Glossary of Terms | CDC

Acellular vaccine: Listen [MP3]
A vaccine containing partial cellular material as opposed to complete cells.

Acquired Immune Deficiency Syndrome (AIDS): A medical condition where the immune system cannot function properly and protect the body from disease. As a result, the body cannot defend itself against infections (like pneumonia). AIDS is caused by the Human Immunodeficiency Virus (HIV). This virus is spread through direct contact with the blood and body fluids of an infected individual. High risk activities include unprotected sexual intercourse and intravenous drug use (sharing needles). There is no cure for AIDS, however, research efforts are on-going to develop a vaccine.
