Shaken baby syndrome refers to the group of nonaccidental injuries occuring in infants and children as a consequence of violent shaking. The characteristic injuries include subdural and subarachnoid hemorrhages, retinal hemorrhages, traction-typed metaphyseal fracture of long bone and fractures of the ribs. General physical findings may include bruising and burns, but sometimes no extracranial injuries are detected. Affected children are nearly always under 2 years of age or younger. Common symptoms include lethargy, irritability, seizures, increased or decreased muscle tone, poor feeding, impaired consciousness, vomiting and apnea. We experienced a case of shaken baby syndrome in a 3-month-old girl. Although the history of trauma(shaking) is little known, our findings of clinical and radiographic features corresponded to shaken baby syndrome. (J Korean Pediatr Soc 2000;43:851-855)

The morphologic abnormalities of the endocrine pancreas that underlie persistent neonatal hyperinsulinemic hypoglycemia and are included under the heading "nesidioblastosis" appears to be heterogeneous. This characteristic morphologic finding is ductuloinsular complexes showing endocrine cells budding off the ductoepithelium and merging with adjacent endocrine cell clusters. A case of nesidioblastosis associated with hyperinsulinemic hypoglycemia occurred in a 6/365 year-old male neonate. Microscopic finding of near totally resected pancreas revealed irregular sized islets and ductuloinsular complexes, both of which contained hypertrophied B cells with a few mitosis. Because of persistent hypoglycemia after first operation, he received second operation 8 days after. This histologic finding was more severe comparative to that of first operation. According to these findings, the pathogenesis of nesidioblastosis may be congenital or developmental defect of a kind of compensatory mechanism by unknown stimuli to acquire persistent hypoglycemia.

Primary angiosarcoma of the female reproductive system is extremely rare, and its management is not well understood. We experienced a very rare case of angiosarcoma arising in the uterus of a 37-year-old woman who presented abdominal distension. At laparotomy, the uterus was observed to be enlarged and deformed by multilobulated hemorrhagic mass. Tumor deposits were present on both ovaries and the omentum. The operation consisted of total abdominal hysterectomy with salpingo-oophorectomy, and omentectomy. Microscopic examination showed that the tumor consisted mostly of solid sheets of pleomorphic and spindle cells forming irregular, communicating cleft-like spaces. Well-formed vascular channels lined by atypical endothelial cells were seen in differentiated areas. Some vessels were partially lined by normal endothelial cells and partially by neoplastic endothelial cells. Papillary architecture composed of epithelioid tumor cells was noted in a focal area. The tumor cells were immunoreactive for factor VIII-related antigen, Ulex europaeus agglutinin-1, CD31 and CD34. Weibel-Palade bodies were not seen in the tumor cells. She received adjuvant chemotherapy, but died 13 months after the diagnosis.

We experienced a case of adenocarcinoma arising in sacrococcygeal teratoma. The patient was a 52-year-old woman. She was admitted due to one month of sacral pain. She had a sacral mass since birth. On physical examination, anal fistula was present at the perianal area and pus drainage was noted. MR image showed multiple variable-sized cysts with inhomogeneous density. Resected specimen, mesuring 12.5 7.0 cm in diameter, showed multiple variable-sized cystic lesions admixed with grayish solid portion. The cysts contained mucoid material. The microscopic examination showed mature teratoma composed of cysts lined by pseudostratified ciliated columnar epithelium, intestinal mucosa, mature cartilage, bone, and fat tissue. A moderately differentiated adenocarcinoma developed from the cystic area in the mass.

OBJECTIVE: The present study was undertaken to examine the effects of magnesium ion in the culture medium on the development of mouse fertilized oocytes either before or after pronuclear formation, and to investigate whether the effect of magnesium ion is related with the redistributional change of mitochondria. METHODS: Fertilized oocytes obtained from the oviducts of mice at 15 hr after hCG injection before pronuclear formation (pre-PN) or 21 hr after hCG injection after pronuclear formation (post-PN) were used. The embryos were cultured for 3 days with basic T6 medium-magnesium free and various concentrations of magnesium ion, 0.0, 0.5, 1.0, 2.0, 4.0 or 8.0 mM, respectively. After culture, the developmental stages of embryos and the number of nuclei were evaluated. To observe the effects of magnesium ion on the mitochondrial distribution, fertilized oocytes were collected at 21 hr after hCG injection and cultured for 6 hr with various concentration of magnesium ion. As a control, fertilized oocytes with pronuclei at 27 hr after hCG injection were used. RESULTS: The concentration of magnesium ion to accelerate the in vitro development of mouse fertilized oocytes appeared to be at 2.0 mM for the pre-PN and the post-PN stage embryos. In the mitochondrial redistribution patterns, the embryos cultured in 2.0 mM concentration of magnesium ion showed the highest percentage (22.6%) of distinct perinuclear clustering pattern comparing to other experimental group. CONCLUSION: The effect of magnesium ion may be related to the cytoplasmic redistribution of mitochondria. This relationship seems to connect the developmental competence of preimplantation mouse embryos in vitro. These results can suggest that higher concentration of magnesium ion (2.0 mM) than those of conventional culture medium (0.2~1.2 mM) is more suitable for in vitro culture of preimplantation mouse embryos.

Transfer of large quantities of fetal blood across the placental barrier to the maternal circulation is a rare occurrence which results in severe anemia in the newborn infants. This phenomenon is believed to occur most often during labor and delivery and apparently, is more frequent when abnormal obstetric conditions are present. However, fetal erythrocytes have been identified in the naternal circulation throughout most of pregnancy indicating some degree of constant or intermittent transplacental transfusion. We experienced a case of stillbirth due to large amount of fetomaternal transfusion. Acid elutionl test of maternal blood was positive and direct and indirect Coombs test was negative. Ultrasonographic finding on abdomen and cranium to rule out the internal hemorrhage was normal. We report a case of stillbirth due to fetomaternal transfusion with a brief review of related literatures.

9.Dose Characteristics of Stereotactic Radiosurgery in High Energy Linear Accelerator Photon Beam.
Journal of the Korean Society for Therapeutic Radiology 1992;10(2):137-146
Three-dimensional dose calculations based on CT images are fundamental to stereotactic radiosurgery for small intracranial tumor. In our stereotactic radiosurgery program, irradiations have been performed using the 6 MV photon beam of linear accelerator after stereotactic CT investigations of the target center through the beam's-eye view and the coordinates of BRW frame converted to that of radiosurgery. Also we can describe the tumor diameter and the shape in three dimensional configuration. Non-coplanar irradiation technique was developed that it consists of a combination of a moving field with a gantry angle of 140degree, and a horizontal couch angle of 200degreearound the isocenter In this radiosurgery technique, we provide the patient head setup in the base-ring holder and rotate around body axis. The total gantry moving range shows angle of 2520 degrees via two different types of gantry movement in a plane perpendicular to the axis of patient. The 3-D isodose cuties overlapped to the tumor contours in screen and analytic dose profiles in calculation area were provided to calculate the thickness of 80% of tumor center dose to 20% of that. Furtheremore we provided the 3-D dose profiles in entire calculation plane. In this experiments, measured isodose cuties in phantom irradiation have shown very similar to that of computer generations.

We investigated pseudophakic residual astigmatism in order to minimize postoperative refractive astigmatism. We examined 110 eyes of 87 patients who had undergone phacoemulsification with small incision and posterior chamber intraocular lens (IOL) implantation. Corneal astigmatism was measured using an autokeratometer (RK-5, canon), refractive astigmatism by manifest refraction, and residual astigmatism by vector analysis. Mean pseudophakic residual astigmatism was +0.47 X 176degrees, predominantly against-the-rule. Variations of pseudophakic residual astigmatism according to sex, age and IOL type were not statistically significant. When performing cataract surgery as refractive surgery, we may consider that pseudophakic residual astigmatism is approximately 0.50D against-the-rule.
