Zika virus was first isolated in from nonhuman primate in 1947. It is in the genus Flavivirus, closely related to other flavivirus like Dengue, West Nile, Yellow fever and Japanese encephalitis virus. Since 2007 epidemic in Yap island, zika virus infections had spread to the countries in Micronesia and South Pacific. In 2015, Zika virus outbreak occurred in Brazil and now more than 40 countries in American continents reported autochthonous infection. The virus is transmitted mainly by Ae. aegypti mosquito with many other Aedes mosquito species known as vector. Recently, Zika virus infection is known to cause severe neurological complications and congenital malformation. In this paper, we will review current knowledge on Zika virus history, biology, clinical characteristics and preventive method.

PURPOSE: To investigate the significance of E-cadherin expression in transitional cell carcinoma of bladder, as the prognostic value. MATERIALS AND METHODS: We have analyzed its immunoreactivity in 41 transitional cell carcinomas using a labelled streptavidin-biotin immunoperoxidase technique on the formalin-fixed and the paraffin-embedded tissues. E-cadherin is a Ca2+-dependent intracellular adhesion molecule of the epithelial tissue and the urothelium. We determined the E-cadherin expression in bladder carcinoma using immunohistochemical method and investigated relationship between pathological and clinical data. RESULTS: The percentage of cases showing weak pattern was higher in cases with high-grade or high-stage tumors as compared with those of low grade or low stage. The E-cadherin was expressed in a normal membranous pattern in all control cases. Abnormal E-cadherin expression was found in 8 of 20 superficial tumors and in 19 of 21 invasive tumors. Abnormal immunoreactivity was related to tumor differentiation and stage. Eight of 13 well-differentiated tumors showed preservation of membranous E-cadherin immunoreactivity, while 2 of 28 moderately and poorly differentiated tumors demonstrated normal staining patterns. CONCLUSIONS: We conclude that the loss of expression of E-cadherin in high grade or high stage transitional cell carcinoma of bladder is associated with bladder wall invasion, indicates metastasis, and may be clinical value in the assessment of prognosis.

Prospective study of gallbladder wall thickness by utrasonography was performed in 38 patients of acute viral hepatitis and 50 normal subjects as a control group from June 1983 to April 1984. The results were as follows; 1.In normal population, the range of gallbladder wall thickness is from 1mm to 3mm with peak incidence in 2mm(66%,33 case). Mean thickness of gallbladder wall is about 1.9±0.6mm. 2. In acute viral hepatitis, the range of gallbladder wall thickness is from 2mm to 8mm with peak incidence in 3mm(34%, 13 case), second peak in 4mm (29%,11 case). Mean thickness of gallbladder wall is about 3.6±1.6mm, which is thicker than normal with statistical signifiance. (p<0.005) 3, In acute viral hepatitis , the mean thickness of glabladder wall is about 4.4±1.8mm in the group of SGOT/ SGPT level above 400 IU, and 2.8±0.8mm in the group of SGOT/SGPT level below 400 IU. This difference is significant statistically. (p<0.05).

1. A study on chest radiographic findings of 54 cases with pneumonia like symptoms was performed. Of 54 cases,8 cases were confirmed to be leptospirosis and 7 cases were leptospirosis combined with Korean hemorrhagic fever.2. Of 8 cases of leptospirosis, 4 cases showed abnormal chest radiographic findings: acinar nodular type 2,massive cofluent consolidation type 2. Of 7 cases of leptospirosis combined with Korean hemorrhagic fever: acinarnodular type 3, massive confluent consolidation type1, and increased interstitial markings type 1 respectively. 3.It was considered to be difficult to diagnose the leptospirosis on chest radiographic findings alone, especiallythe case combined with Korean hemorrhagic fever.

Congenital pseudarthrosis is frequently associated with various stigmata of neurofibromatosis, particularly Cafe-Au-Lait spots and,subcutaneous nodules and in these patients, it is noteworthy that the treatment is very difficult even with extensive operative approach. Also it is interesting to find many controversies on etiological relation between neurofibroma and pseudarthrosis, per se and even the existance of nerve element in and around the tissue of pseudarthrosis. A thirteen years old female patient with definite neurofibromatosis associated with congenital tibial pseudarthrosis treated by intramedullary nailing and massive bone graft is reported.

Foreatiers disease is a peculiar type of ankylosing hyperostosis of the spine characterized by ossification of the anterior and right lateral aspects of the vertebral column, particularly in the thoracic region. The clinical, pathological and reontgenographic features of the disorder allowed its differentiation from other spinal diseases including ankylosing spordylitis and osteoarthritis. A case of Forestiers disease is presented with brief review of literatures.

BACKGROUND: The aim of this study was to evaluate the sensitivity of a clinicians' self-report method for the detection of nosocomial infections (NIs) in comparison with a total surveillance method in a neonatal intensive care unit (NICU). METHODS: Two surveillance methods were concurrently performed in the NICU of a university hospital during 5 months in 2003. Clinicians' self-report surveillance (CSRS) was based on the retrospective verification of monthly reports of positive bacteriologic results by NICU clinicians. Total surveillance (TS) was done prospectively by an infection control nurse based on chart review and laboratory data. RESULTS: One hundred fifty nine patients accounting to 2759 patient-days were included in the study. Twenty-seven NIs among 26 patients were identified by TS. The sensitivity of CSRS compared to TS was 14.8% (4 of 27 NIs). The specificity was 98.5% (131 of 133 non-NIs). Kappa measures of agreement were -0.309. CONCLUSIONS: Our results confirm that the retrospective review of charts and laboratory data by clinicians lacks sensitivity and agreement for the surveillance of nosocomial infections.

Morning glory syndrome is a rare congenital clinical entity that results from abnormal optic nerve development. In 1970, Kindler reported on ten patients having this anomaly and coined the term "morning glory syndrome" because of its similarity to the flower. The ophthalmoscopic picture is characterized by an enlarged pink excavated optic disk containing a mass of white tissue at its center, surrounding the disk is a wide, grey, elevated annulus of chorioretinal pigment disturbance. The retinal vessels appear as multiple radially oriented branches near the edge of the disk. Vision is usually markedly reduced. We experienced four cases of morning glory syndrome demonstrating various ophthalmoscopic and fluorescein angiographic features.

An ABO discrepancy was observed in a 19-year-old man clinically diagnosed as congenital hypogammaglobulinemia. The patient's red cell was typed as group O, and his serum had no ABO isoagglutinins. Absence of A antigen and B antigen on patient's RBC was confirmed by adsorption- elution test and saliva test. A-transferase and B-transferase activities were not demonstrated in patient's serum. Patient's serum protein electrophoresis revealed hypogammaglobulinemia pattern, and immunoglobulin levels were markedly decreased. Complete absence of B lymphocytes was observed on patient's lymphocyte subset profile. Patient's father and mother were typed as blood group O and no abnormalities were recognized in their serum protein electrophoresis patterns and immunoglobulin concentration.
