Prenatally diagnosed neuroblastomas have been reported in increasing numbers over the past several years. The vast majority are in favorable stages of the disease (stage I, II, IV-S). The authors experienced one case of stage IV-S neuroblastoma of the adrenal gland with liver metastasis, which regressed spontaneously after removal by adrenalectomy. This patient was noticed to have an abdominal mass at prenatal ultrasonography performed at 36weeks of gestation. This tumor was a neuroblastoma of the left adrenal gland with multiple liver metastases. Left adrenalectomy and liver biopsy were performed at 3 months of age. Thirty-eight months after surgery, an MRI demonstrated that the hepatic metastatic lesions had completely regressed without chemotherapy or radiation.

The infantile polycystic kidney disease is rare fetal urinary tract anomaly. It is inherited with an autosomal recessive pattern and recurrence rate is 25%. The gene locus is on chromosome 6p. The pathogenesis of infantile polycystic kidney is the primary defect of the collecting ducts. The ultrasonographic finding of infantile polycystic kidney is oligohydramnios, bilaterally symmetrical enlarged kidneys with maintenance of their reinform shape. The differential diagnosis with adult polycystic kidney disease is important. The massive enlargement of the kidneys is rarely seen in adult polycystic kidney disease and the examination of the parents and other members of the family is helpful to confirm the adult polycystic kidney disease. If there is severe renal involvements, stillbirth or neonatal death secondary to pulmonary hypoplasia would be developed. If it were diagnosed before viability, termination of pregnancy is recommended. In a fetus at risk, diagnosed after viability, pregnancy termination is also recommended since this condition is uniformly fatal. We present a case of infantile polycystic kidney.

Purpose: The purpose of our study is to examine early radiographic findings and clinical signs of failure of the microstructure surface HA-coated acetabular cup. Material and methods: This study included 41 revisions of 204 THA with hydroxyapatite-coated acetabular cup from April 1992 to November 1996. Radiolucent line around cups, change in the cup angle and osteolysis were evaluated in serial radiographs. Acetabular cup was defined as loosening if any movement occurred at the bone and socket interface by manual rotation and extension force intraoperatively or migration of more than 2 mm and change of the cup angle by more than 5 degrees in radiographs. Results: The radiolucent line was observed in 12 of the 41 hips at an average of 55.4 months postoperatively and was most commonly located in zone III. All of the 12 hips showing radiolucent lines were classified as loosening by radiographically in 8 cases and intraoperatively in 4 cases. Radiographic loosening occurred at an average of 28.8 months after the appearance of a radiolucent line. Inguinal pain was noted in 18 of the 19 cases revised for acetabular cup loosening. Conclusion: The most important radiographic finding for the early diagnosis of loosening was progressive radiolucent lines, which occurred most frequently in zone 3.

Acardiac twinning affects 1 in 100 monozygotic twin pregnancies and 1 in 35,000 pregnancies overall. This condition is characterized by the absence or rudimentary development of fetal heart, and associated with various anomaly. The presence of an acardiac twin requires the normal (or "pump") twin to provide circulation for itself, as well as the acardiac sibling. The acardiac malformations are uniformly fatal in the affected twin, and mortality in the co-twin is as high as 55%. The principal perinatal problems associated with acardiac twinning are pump-twin congestive heart failure, maternal hydramnios, and preterm delivery. We recently experienced a case of acardius anceps associated with a normal male infant, so present with a brief review of the literature.

OBJECTIVES: Xylitol is an effective anticarious natural sugar substitute, by inhibiting the virulence of Streptococcus mutans (S. mutans). However, long-term xylitol consumption leads to an emergence of the xylitol-resistant (XR) strains. This study aimed to confirm the general characteristics, mRNA expression of gtf genes, and adhesive ability of the xylitol-sensitive (XS) and XR S. mutans , by xylitol-treated concentrations. METHODS: S. mutans KCTC3065 was maintained in TYE medium, containing 0.4% glucose with 1% xylitol for 30 days at 37degrees C, 10% CO2 to form XR strain and the same procedures, without xylitol, were repeated for the formation of XS S. mutans. Both XS and XR were cultured by xylitol-treated concentrations (0%, 0.1% and 1%), then, general characteristics, such as growth and acid production, mRNA expression of gtf genes and adhesive ability were analyzed. RESULTS: Xylitol reduced the cell growth of XS S. mutans in a dose-dependent manner, but did not reduce the XR. Xylitol inhibited acid production of XS in a dose-dependent manner. However, it did not inhibit that of XR. Xylitol reduced the gtfB and gtfD mRNA expression of the XS S. mutans, which the genes synthesized soluble and insoluble extracellular polysaccharides, but not reduced that of the XR. By a microtiter plate assay, biofilm formation was more reduced in the XR strains, which means biofilm's adhesive ability of XR S. mutans was lower than that of the XS. CONCLUSIONS: These results indicate that a lower level of adhesive ability for XR S. mutans is related with mRNA expression level of gtf genes, which suggested that the XR strains may be less cariogenic than that of the XS.
