Pure, nongestational ovarian choriocarcinomas is extremely rare. Most ovarian choriocarcinoma are combined with other malignant germ cell tumors or can arise as a metastaais from a primnry gestational choriocarcinoma. We experienced a case of primary ovarian choriocarcinoma that probably was associated with a past history of the mixture of germ cell tumor and present it with a review of literature.

Fetal bilateral renal agenesis is a lethal congenital anomaly. An early and reliable prenatal diagnosis is extremely important as it may offer options for pregnancy termination as early as possible. The criteria for the ultrasonographic diagnosis of bilateral renal agenesis are severe oligohydramnios, nonvisualization of the bladder, and the empty renal fossae. However, severe oligohydramnios makes it difficult to diagnose the disease because of poor sonographic resolution. We present a case of fetal bilateral renal agenesis diagnosed by ultrasonography after amnioinfusion at 19 weeks gestation.

OBJECTIVES: To determine the effectiveness and clinical utility of antenatal corticosteroids in the reduction of neonatal morbidity and mortality on preterm birth Material and method: Neonatal outcomes of 312 preterm babies were evaluated retrospectively. One hundred and two preterm babies(study group) were given dexamethasone more than 1 dose antenatally and 210 preterm babies(control group) were not given dexamethasone antenatally. Antenatal steroids were administered in the form of four 5mg intramuscular doses of dexamethasone 12 hours apart. Maternal and neonatal outcomes of study group were compared with those of control group. Student t- test, x2 test, Fisher's exact test, and logistic regression analysis were used where appropriate. p-value< 0.05 was considered significant. RESULTS: Antentenatal corticosteroid significantly decreased the incidence of RDS(OR:0.47, 95% CI:0.25-0.86), IVH/PVL(OR : 0.32, 95% CI : 0.12-0.86), necrotizing enterocolitis(OR : 0.49, 95% CI : 0.25-0.98), and neonatal death(OR: 0.30, 95% CI: 0.10 - 0.89) in preterm delivery. In the presence of PROM, antenatal corticosteoid seemed to have no protective effect on the neonatal complications such as RDS, IVH/PVL, NEC, PDA, and neonatal death. CONCLUSIONS: Antenatal administration of corticosteroids was effective to decrease the incidence of neonatal morbidity and neonatal mortality in the preterm neonates with no apparent maternal complications.

Werniche's encephalopathy is clinically characterized by the acute onset of global confusion, ataxia, gaze paresis, and nystagmus. It result from a deficiency in thiamine, an essential coenzyme in intermediate carbohydrate metabolism. The prompt use of thiamine prevents progression of the disease and reverses those lesions that have not yet progressed to the point of fixed structural change. We experienced a case of Wemiches encephalopathy associated with hyperemesis gravidarum, which happens to the patient who are injected only dextrose without thiamine. Therefore, we emphasize the need of thiamine replacement in hyperemesis gravidarum.
