Hirsutism is a condition of unwanted, male-pattern hair growth in women. Hirsutism results in excessive amounts of stiff and pigmented hair on body areas where men typically grow hair like face, chest and back. The amount of body hair is mainly determined by genetic makeup. Hirsutism may arise from excess male hormones called androgens, primarily testosterone. Hirsutism may also be due to a family trait also. Hirsutism is stiff and pigmented body hair, appearing on the body where women don't commonly have hair mainly the face, chest and back. Due to high androgen levels cause hirsutism, other signs may develop over time, this is called virilization. Signs of virilization may include: deepening voice, balding, acne, decrease in breast size and enlargement of the clitoris. Hirsutism is caused by polycystic ovary syndrome, cushing's syndrome, congenital adrenal hyperplasia, tumors and medications.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
