Ascariasis is probably the most common helminthic infestation of man, but it seldom causes severe illness. Pathologic conditions of Ascaris may be caused by adult worms, eggs or larvae. We describe a case of Ascaris egg granulomas that were found incidentally on the surface of the liver in a 75-year-old woman who had undergone a segmentectomy for an intrahepatic stone. Grossly, there were several yellowish calcific nodules of 0.4 cm in diameter on the lateral surface of the left lobe of the liver. Microscopically, the lesions were located in the hepatic capsule and consisted of fibrocalific nodules with many eggs. The eggs were round to oval, thick-shelled and measured 50~75x30~50 um. Most of the morphologically preserved eggs were fertilized eggs, but they had smooth shells without external protein coats. This case is of interest for the unusual location of the lesion, the presence of eggs without mammillation, and the association with the intrahepatic stone.

Rabies is a fetal viral encephalitis to which all mammals, including man are susceptible. This virus, the genus of Rhabdovirus, is usually present in the saliva of infected animals and is transmitted by their bite. As a rule the virus enter the CNS by ascending along peripheral nervous system and extremely variable in extent. Negri bodies are appear in about 75% of cases. These bodies are eosinophilic, usually rounded inclusions and is located in the cystoplasm of the neurons, most frequently in the pyramidal neurons of the Hippocampus and the Purkinje cells of the cerebellum. We have experienced a case of canine rabies that showed Negri bodies in the Purkinje cells along with diffuse degenerative encephalitis and perivascular mononuclear cells infiltration. The Negri bodies were best demonstrated by Negri body staining although routine H-E staind was also useful. There inclusion bodies were located exclusively in the cytoplasm, and were found occasionally. Electron microscopic findings of the Negri bodies showed aggregates of bulletshaped nucleocapsids. We report a Negri body found in the brain of rabid dog with the light and electron microscopic findings.

BACKGROUND: Carbapenem-resistant Enterobacteriaceae (CRE) with acquired metallo β-lactamase (MBL) resistance have been increasingly reported worldwide and associated with significant mortality and morbidity. Here, an outbreak of genetically related strains of Klebsiella pneumoniae producing the imipenemase (IMP)-1 MBL in a medical intensive care unit (MICU) in Korea is reported. METHODS: Since isolating carbapenem-resistant K. pneumoniae (CRKP) at the MICU of the hospital on August 10, 2011, surveillance cultures for CRE in 31 hospitalized patients were performed from August to September 2011. Carbapenem resistance was determined based on the disk diffusion method outlined in the Clinical and Laboratory Standards Institute guidelines. Polymerase chain reaction (PCR) was performed for genes coding for β-lactamase. Associations among isolates were assessed via pulsed-field gel electrophoresis (PFGE). In addition, a surveillance study of environmental cultures and health-care workers (HCWs) was conducted in the MICU during the same time frame. RESULTS: During the study period, non-duplicated CRKP specimens were discovered in four patients in the MICU, suggestive of an outbreak. On August 10, 2011, CRKP was isolated from the sputum of a 79-year-old male patient who was admitted to the MICU. A surveillance study to detect additional CRE carriers by rectal swab revealed an additional three CRKP isolates. PCR and sequencing of the four isolates identified the presence of the IMP-1 gene. In addition, PFGE showed that the four isolated strains were genetically related. CRE was not identified in specimens taken from the hands of HCWs or other environmental sources during surveillance following the outbreak. Transmission of the carbapenemase-producing Enterobacteriaceae strain was controlled by isolation of the patients and strict contact precautions. CONCLUSIONS: This study shows that rapid and systemic detection of CRE and strict infection controls are important steps in preventing nosocomial transmission.

PURPOSE: It has been known that there are several areas of T2 hyperintensities in normal white matter of brain, such as terminal zones of myelination, ependymitis granularis, ones of posterior internal capsule, and perivascular space. The aim of our study is to demonstrate another region of T2 hyperintensities in normal pediatric age group. MATERIALS AND METHODS: We have studied brain MR for 10 normal volunteers and 35 patients without having intracranial lesions in pediatric age group(3-19 years). RESULTS: In 5 among 45 cases, focal T2 hyperintensities were seen in the parietal periventricular white matter beneath the postcentral gyri. They were noted as poorly defined, 5--10mm sized areas of increased signal intensities on T2 weighted axial images. They were also characterized by bilateral, posteromedially oriented, short band-like or oval areas. Interestingly, they were directly continuous with the T2 hyperintensity of posterior internal capsule. In spite of the relatively high frequency in the pediatric population as in our study, this finding has not been reported in the asymptomatic adults. CONCLUSION: The results show that the bilateral anterior parietal hyperintense areas may be another terminal zones of delayed myelination affecting the parietopontine tract. They should be differentiated from pathologic T2 hyperintensities by their characteristic findings.

Members of the genus Acinetobacter are recognized as newer pathogens of the nosocomial infection with an increasing frequency in recent years. Strains that belonged to A. calcoaceticus-A. baumannii complex (genomic species 1, 2, 3, and 13TU) were major groups associated with nosocomial infection. Phenotypic identification was unreliable and laborious method to classify Acinetobacter strains into 19 genomic species. Rapid and reliable identification of clinical isolates is essential to diagnosis and epidemiology of Acinetobacter. We investigated the suitability of amplified ribosomal DNA restriction analysis (ARDRA) to identify genomic species of 131 Acinetobacter isolates. The 16S rRNA genes (ribosomal DNA) were enzymatically amplified and the amplified PCR products were restricted independently with the enzymes, AluI, CfoI, and MboI. Genomic species of Acinetobacter was classified by the combinations of restriction patterns. The analysis was showed that restriction profiles were characteristic for each genomic species. One hundred fourteen isolates were identified as A. baumannii, twelve were identified as genomic species 13TU, and one was identified as genomic species 3. Four isolates were found to be unknown organisms. All of the isolates which were identified to A. baumannii by phenotypic tests were completely discriminated into A. baumannii and genomic species 13TU by ARDRA. This study demonstrates that ARDRA is a rapid and simple techniques for the identification of Acinetobacter species according to the genomic species.

Schizophrenia is a devastating mental illness that can lead to deterioration in the social and occupational functioning of affected individuals with a major cost to society. A wide range of studies suggest a genetic component to the inheritance of schizophrenia. The molecular genetic studies on schizophrenia have been actively performed since late 1980s. In linkage studies, no loci were replicated across studies and there were no loci surpassing genome-wide significance. Candidate gene association studies showed generally inconsistent results and there were no enrichment of smaller P-values. In the GWAS era, the community has coalesced into large international consortia. The largest schizophrenia GWAS to date is 50,000 samples and efforts are ongoing to accumulate 50,000 cases and 50,000 controls as part of 'PGC2' collaboration. With the limitation of GWAS results, several alternatives are being explored. In genotyping, the concepts of allelic spectrum including from common polygenic to rare penetrant variation are emerging. Phenotypes include all phenomena beyond DNA. The developments in transcriptomic & proteomic approach and intensive research on endophenotype will bring crucial insights into the nature of schizophrenia in the future. But there still remains our task about research on many factors including environment that influence gene expression (epigenetics), age, and gender.
