The information obtained from epidemiology of brain tumor provide the key to the natural history of brain tumors and could be used for many different things, among others, the planning of hospitals and hospital care facilities and working out the medical requirements for each region. To cope with changing needs in this field due to the application of medical insurance to all Korean citizens from July 1. 1989, the brain tumor registries of various countries were reviewed and suggestions were made about Korean Brain Tumor Registry that should be prepared in the near future.

Toxoplasmosis is a disease caused by the infection with an obligate intracellular parasite, Toxoplasma gondii. The most common manifestation of acute toxoplasmosis in an immunocompetent patients is a cervical lymphadenitis. The prevalence of toxoplasmosis in Korea is much lower than in those of other countries, including the United States and most European countries. We report three cases of toxoplasma lymphadenitis arising in the posterior cervical lymph nodes of immunocompetent patients with typical histologic findings and positive serologic results. The etiology, epidemiology, clinical features, diagnostic methods, and management of toxoplasmosis are also reviewed.

The authors performed a clinical analysis of 80 cases of pediatric brain tumors which were verified by surgical operation during 10 years from Sept. 1978 to Aug. 1987 in the Department of Neurosurgery, Korea University, Seoul, Korea. These tumors were divided according to modified WHO classification. The results were as follows: 1) The male to female ratio was 1.42:1. 2) The most common pediatric brain tumor was gliomas(48.7%), and followed by medulloblastome(17.5%), germ cell tumor(7.5%), craniopharyngioma(6.2%), meningioma(5.0%). 3) Supratentorial tumors(57.5%) were more frequent than infratentorial tumors(42.5%). 4) Headache and vomiting were the most common presenting symptoms and papilledema was the most common sign. 5) Hydrocephalus was developed at supratentorial(58.7%) and infratentorial(73.5%) region. 6) Postoperative mortality was 7%.

Chorioangioma is the most common benign tumor of the placenta and associated with adverse perinatal outcome. The prevalence of chorioangioma of the placenta is about 1 percent. The most placental chorioangioma has no clinical significance. But the uncommon large (greater than 5 cm in diameter) chorioangioma may produce both maternal and fetal complications, such as polyhydramnios, preterm labor, fetal heart failure, hydrops fetalis, fetal growth restriction, fetal microangiopathic hemolytic anemia, fetal thrombocytopenia, toxemia of pregnancy, maternal thrombocytopenia, and maternal coagulopathy. The ultrasonography and Color Doppler are used for diagnosis of these lesions. If chorioangioma is suspected, Color Doppler study is informative to confirm the presence of the vascular channels. We report a case of multiple chorioangioma combined with oligohydramnios and discuss the noxious effects of this benign tumor on the mother and the fetus.

Cushing's syndrome in pregnant women is rare and difficult to be diagnosed because of the syndrome's association with oligomenorrhea or amenorrhea and the changes in cortisol metabolism during normal pregnancy. Cushing syndrome in pregnancy is usually confused with complicated pregnancy, such as preeclampsia or gestational diabetes, and its rarity leads to a low degree of clinical suspicion, often delaying diagnosis. We experienced a case of Cushing's syndrome in pregnancy, which had been considered as the severe preeclampsia and gestational diabetes due to uncontrolled hypertension and hyperglycemia. The pregnancy was terminated with an emergency cesarean operation at 30 weeks of gestation because of severe preeclampsia. In consequence of the evaluation about the Cushing's syndrome after delivery, the adrenal cortical adenoma of right adrenal gland was diagnosed and laparoscopic adrenalectomy was performed.
