Epistaxis can be caused by a number of different factors. In children, it is most often caused by chronic nose picking or the use of steroid nasal sprays. In adults, it is usually caused by nasal steroids sprays, nasal septal deviations (from old nasal fractures), the use of appliances for obstructive sleep apnea (CPAP and BiPAP masks), and certain disease states that lead to excessive bleeding, such as hereditary hemorrhagic telangiectasia (HHT).

Recurring nosebleeds have multiple causes, resulting in a year round problem. Major related causes include: Allergy sufferers who dry up their nasal passages with Rx and/or OTC medications and start to experience nosebleeds Sufferers of chronic blood based diseases, such as hemophilia and Hereditary Hemorrhagic Telangiectasia (HHT) Over 90 % of nosebleeds are not life threatening.

Ninety-five percent of all nosebleeds are what are called anterior nosebleeds (nosebleeds in the lower part of the nasal cavity). NasalCEASE will work for all anterior nosebleeds regardless of the cause.

In the U.S., it is estimated that over 30 million people have recurrent nosebleeds, with the average nosebleed sufferer having over 7 different episodes a year. It is common in young children and middle-aged adults to the elderly.

In anime and manga a nosebleed represents sexual excitement (it is thought to be a substitute for ejaculation), which is why it often happens when male characters walk in on females taking a bath...

Almost all teenagers get acne at one time or another. You haven't done anything to cause your acne. It's not your fault if you have it. Pimples are caused when oil ducts in the skin get plugged up and then burst, causing redness and swelling. Although there are many myths about acne, the following are the three main factors that cause it. When you begin puberty, certain hormones, called androgens, increase in both males and females.

Several factors contribute to the development of acne. The primary problem is that the abnormal flaking of cells inside the hair follicle leads to the formation of a plug. The plug can enlarge and even rupture the hair follicle. A ruptured hair follicle spills its contents of oil and debris into the skin where it leads to swelling and causes redness (inflammation).

Parts may distort as they solidify and cool in the die, or during ejection from the die. These problems are solvable but usually require discussions between the part designer, the tool designer and the die-casting engineer since they involve increasing draft angles etc. However, part distortion is quite often caused by mishandling during press trimming, polishing etc. or when the parts are clamped in jigs for machining, plating or painting.

Patients with long QT syndrome develop a very fast heart rhythm disturbance known as "Torsade de pointes". This is a form of ventricular tachycardia. This rhythm is too fast for the heart to beat effectively, so the blood flow to the brain falls precipitously causing the sudden loss of consciousness. In most instances, there is no warning prior to syncope.

Melanoma is a malignancy of melanocytes, special cells in the skin which synthesize skin pigment. It is the most rapidly increasing form of cancer in the US. Although all causes of melanoma are not known with certainty, epidemiologic studies suggest that brief, intense exposure to ultraviolet radiation contributes to the development of melanoma.

allergic reaction occurs when your immune system reacts to a foreign substance from the outside world. These foreign substances, normally small proteins, can come from dust mite feces, pollens, molds, and many other natural and man-made objects.

Shorter days of winter and lack of light are considered one cause of seasonal depression, especially for people who move to extreme northern climates, where winter days are very short or seasonal differences in the amount of daylight are extreme.1, 2 However, researchers are studying other possible causes, including disturbances in the body's natural biological clock (circadian rhythms) or problems with the regulation of a brain chemical (neurotransmitter) called serotonin.

Benign prostatic hyperplasia is probably a normal part of the aging process in men, caused by changes in hormone balance and in cell growth.
