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)

This experiment was designed to investigate the histochemical and ultrastructural changes of the proximal tubules and glomeruli of rabbits treated with cyclosporin A (CsA) or cyclosporin A and concomitant administration of prednisolone (PD). Rabbits were given with CsA for 1 week (CsAlW) and for 2 weeks (CsA2W) and CsA plus PD for 1 week (CsA +PDIW) and for 2 weeks (CsA+PD2W). The dose of CsA was 5mg/kg/day i.v. and PD was 1 mg/kg/day i.m. At 1 week and 2 weeks after the treatments, the following items were studied of alkaline phosphatase (ALPase). peroxidase, 5'-nucleotidase (SNU) with the ultrastructural enzymatic changes and electron microscopic changes. CsAlW, CsA2W and CsA +PD2W groups showed a decrease of ALPase activity and CsA+PD2W and CsA2W groups showed weakly increased peroxidase activity CsA2W and CsA+PD2W showed a decrease of 5NU activity. Ultrastructural changes of CsAlW CsA2W and CsA+PD2W groups revealed swollen and disrupted mitochondria, loss of brush border in the proximal tubules and thickening of basement membranes, edematous podocytes and fusion of root processes of podocytes in the glomeruli showing the early stage of nephrotoxicity. The concomitant treatment of PD with CsA eased the nephrotoxicity of CsA within 1 week after the treatment.

Serous cystadenoma of the pancreas, also known as microcystic adenoma or glycogen-rich cystadenoma, is an unusually benign tumor. It is usually large and composed microscopically of many small cysts lined by small, cuboidal or flattened cells containing abundant glycogen. It has been suggested that serous cystadenoma probably arise from the ductular cells or centroacinar cells. Herein, we report on a case of serous cystadenoma of the pancreas in a 55-year-old female. The tumor, measuring 13.5x11.5x10.0 cm, was located in the head of the pancreas and the cut surface revealed a sponge-like appearance due to innumerable tiny cysts containing clear serous fluid. Microscopic analysis showed cystic spaces lined by cuboidal cells with intracytoplasmic glycogen.

Synthetic genes encoding the gag p24 and the part of the envelope protein gp41 of the human immunodeficiency virus (HIV-1) were cloned and overexpressed as fusion proteins in Escherichia coli, using an expression vector carrying 77 promoter and the poly-histidine leader sequence. The overexpressed p24 fusion protein was purified by centrifugation, Ni-affinity chromatography and CM-sepharose chromatography The overexpressed gp41 fusion protein was purified by centrifugation, C4 chromatography and DEAE-sepharose chromatography. The purified fusion proteins showed a high level of purity and immunoreactivity in SDS-polyacrylamide gel electrophoresis and western blot analysis. These results suggest that this prokaryotic expression-purification method is suitable for obtaining a large amount of the viral antigen which may be useful for screening of antibodies to HIV-1 in human blood samples.

In glaucoma patients, optic nerve head analysis is very useful in early detection and progression during follow-up. Among optic nerve head analysis methods, the confocal laser tomographic scanner(Heidelberg Retina Tomograph: HRT) is actively studied for accurate and highly reproducible analysis.We analyzed the optic nerve head of 62 normal eyes(male 40 eyes, female 22 eyes) in third decade of Korean with HRT, and calculated the mean value of each parameters in HRT and evaluated the difference between men and women. We also studied the distribution fo the value of each parameter in normal third decade of Korean. In addition, for the parameters of Rim/Disc area ratio, we calculated the mean value in 6 divisions of optic nerve head.The mean value of Disc area was 2.039mm3, Cup area 0.593mm3, rim area 1.716mm3 and Cup/Disc area ratio 0.237. Rim volume, Maximal cup depth, Height variation contour, Mean retinal nerve fiber layer thickness, and Retinal nerve fiber layer cross sectional area were statistically different between men and women. For Rim/Disc area ratio, the maximal value was noted in nasal inferior(0.873) region, and the minimal value was in temporal(0.579) region. There was no statistically difference between men and women in Rim/Disc area ratio.

Hypertonic or hypernatremic dehydration, which is uncommon in pediatric patients beyond infancy, has a distinct pathophysiology that differentiates the clinical presentation and management from other forms of dehydration. Severe hypernatremia may precipitate central nervous system injury, seizures, intracerebral bleeding, retardation, and even death. Causes of hypernatremia include inadequate water intake, salt overload, extrarenal water loss, defective osmoregulation, and water loss with simultaneous gain of solute. We experienced a case of hypernatremia due to esophageal foreign body. These authors reported a case with review of literatures.
