PURPOSE: To report a case of a 9-year-old girl who complained of a floater symptom due to preretinal hemorrhage, subdural hemorrhage and arachnoid cyst. CASE SUMMARY: A 9-year-old girl presented to our clinic with floater symptom in her right eye and a headache. Her corrected visual acuities were 20/20 in both eyes. Preretinal hemorrhage around the optic disc in both eyes was observed. Brain MRI revealed subdural hemorrhage on the frontal, temporal, and parietal lobes, and the arachnoid cyst in the right fronto-temporal lobe. One year later, the preretinal hemorrhages were absorbed. CONCLUSIONS: Arare case of concomitant preretinal and spontaneous subdural hemorrhage with arachnoid cyst was presented. The utilization of brain MRI is recommended to determine underlying causes when fundus examination reaveals retinal hemorrhage without trauma, systemic disease and neurologic symptom.

The mainly used polymeric material for the denture is PMMA because of its cost and easiness to handle. So it was widely used material among dentists for past decades. But the acrylic-based denture materials have several common weak points such as shrinkage after curing and lack of strength. In order to solve these problems, we adapted one of hybrid system using acrylic polymer and vinyloligosilsesquioxane(POSS). POSS, which is a well known expandable monomer during polymerization process, may eventually suppress volumetric shrinkage. And the hybrid system makes it possible for the polymer to be stable in various severe conditions. Eight different kinds of samples were designed and synthesized. Each samples were characterized with dynamic mechanical analyser(DMA) to confirm their thermodynamic properties, fractured to analyze the cross-sectional morphology of the samples. And elongation, flexural and impact tests were also executed to evaluate the mechanical properties of the samples. From the results, hybrid composites had well defined crosslinked network structure compared to the widely used denture materials, and the mechanical strength improved without changing any surface condition as increment with POSS ratio in hybrid system. Fractured morphology showed homogeneous surfaces in spite of mutli component system, therefore we can conclude that the adoption of the POSS brought the reinforcement of the denture resin.

The Korean hemorrhagic fever (KHF) is an acute febrile disease with characteristic of fever, bleeding tendency, and renal failure. There are many complications of Korean hemorrhagic fever such as infection, anemia, internal bleeding, hypopituitarism, respiratory, and neurologic complication. A few cases were reported on acute pancreatitis with hemorrhagic fever abroad, but there was no case about Korean hemorrhagic fever with acute pancreatitis in this country. We experienced a case of Korean hemorrhagic fever associated with suspected acute pancreatits. With review of articles, we report a case of 51 year-old woman with KHF, where acute pancreatitis developed during management.

The case of a cyanotic infant with a rare combination of atypical pulmonary artery sling, imperforate anus, absence of the left kidney, interruption of the inferior vena cava, left side hemihypertrophy and diffuse-type pulmonary arteriovenous fistula is described. The clinical features were confusing, because of compounding abnormalities involving the respiratory tract and pulmonary circulation. The diagnostic approach to the etiology of cyanosis is discussed and the embryonic origin of pulmonary artery sling is reviewed.

Cervical spondylolysis is an extremely rare abnomality of unknown etilogy, first described by Hadley. It is defined s a corticated cleft between the superior and inferior articular facets of the articular pillar, the cervical equivalent of the pars interarticularis in the lumbar spine. A 50-yar-old woman was presented with occipital headache, and pain in the upper neck region. Neurological examination revealed the patients inability to walk because of quadriparesis with mild hypesthesia in both hands and feet. The DTR was hyperactive and pathological reflexes, including Babinski's and Hoffman's, were positive bilaterally. CT showed the bilateral pars interarticularis defects and spinal canal stenosis. MRI revealed signal alteration on the upper spinal cord which was compromised due to the hypertrophied ligamentum flavum. Decompressive laminectomy of C2 was performed and the patient's neurological deficits had recovered to some extent and resulting to her ability to walk without assistance.
