Hirsutism with virilization
Article Abstract:
A case is described of a 56-year-old woman with hirsutism, the excessive growth of hair or the presence of hair in unusual places, particularly when it occurs in women. The patient had developed an increase in facial hair, acne, and hoarseness of the voice over the past three years. She had a history of cervical carcinoma (cancer of the cervix), which required treatment by hysterectomy, the surgical removal of the uterus. She also had obesity; high blood pressure; diabetes; hypothyroidism, or abnormally low activity of the thyroid gland; migraine headaches; and was a smoker. The patient was shown to have elevated levels of testosterone and dehydroepiandrosterone, and decreased levels of follicle-stimulating hormone, thyrotropin, and cortisol. The drug spironolactone was given to treat the hirsutism, and caused a temporary decrease in testosterone levels. The steroid drug dexamethasone decreased testosterone levels to values that were still higher than the normal range. Examination of the ovaries and adrenal glands using imaging techniques did not reveal abnormalities. However, sampling of the blood from the ovarian and adrenal veins showed high levels of testosterone, with the abnormality localized to the right ovary. The patient underwent exploratory laparotomy, the surgical opening of the abdomen to examine the abdominal organs. A hilar cell tumor of the right ovary was discovered. Most patients with hilar cell tumors have masculine symptoms, such as hirsutism and a hoarse voice. The tumors usually occur in only one ovary and measure about one to three centimeters in diameter; they are difficult to feel by palpation. Hilar cell tumors are generally benign, although masculine symptoms do not resolve completely. (Consumer Summary produced by Reliance Medical Information, Inc.)

Topographic mapping, Loran-C, and GPS accuracy for aerial telemetry locations
Article Abstract:
Aerial telemetry is commonly used to determine the movements and home-range sizes of wildlife. Radiomarked animals can be tracked from an aircraft using systems such as LORAN-C, GPS and topographic mapping. A comparison of the precision and accuracy of six methods for recording animal movement is presented. The methods tested are LORAN-C, mapping, bias-adjusted LORAN-C, NGPS, UGPS and DGPS. Details of the study are presented.
