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.

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.

This study is based on 155 patients of congenital me colon. For the diagnosis, 93 cases were histologically proven and the remaining 63 cases were diagnosed on clinical basis including barium enema or surgical gross findings. On histologic examination, 80 cases(86%) showed typical features of absence of ganglion cell in the myenteric plexus and the 13 cases(14%) had atypical features which were segmental absence Of ganglion cell in one case. There we 127 males(82%) and 28 females(18%). The age at diagnosis was younger than 30 days in 87 cases(56%), I month to 1 year in 39 cases(25%) and older than I year in 29 cases(18%). The levels of aganglionosis were variable: short segment (rectosigmoid) in 134 cases(86%), intermediate segment (more proximal colon) in 14 cases(100%). and 6 cases(4%) had total aganglionosis. Common clinical presentations were abdominal distention, delayed meconium passage or bilious vomiting in neonate, and chronic constipation in infancy or childhood. Following initial colostomy or ileostomy, a definitive procedure was performed in 151 cases(Duhamel type in 150 cases; Soave type in 2 cases; Swenson type in 3 cases). Frequently associated problems after definitive procedure were persistent constipation(ll%) due to septum formation, fecaloma, remnant aganglionic segment and rectal stenosis. Overall mortality rate was 4%, and increased mortality was associated with enterocolitis(14%) which was the most frequent cause of death. The follow-up study longer than 3 months was available in 138 patients who underwent a definitive procedure(mean 2 year 11 months). Seventy-three cases(53%) had normal bowel function, 38cases(27.5%) had occasionally used enema or stool softners, and 27 cases(19.5%) had severe constipation or soiling. The bowel habit improved with time, and were considered normal in 60% of patients after follow-up more than 3 years. The results of definitive procedures for congenital megacolon including Duhamel operation was satisfactory, and long-term follow-up appeared an important and critical component of patients'care.

To know the effect of subconjunctival injection of liposome encapsulated cytarabine on proliferation of conjunctival fibroblasts, the conjunctiva was isolated at 180 degrees from the injection site 3 days after subconjunctival injection of the normal saline (control), cytarabine, liposome encapsulated cytarabine, and 1 day after injection of cytarabine, and then those were inoculated in the culture media of fibroblasts. In the case of 3 days after injection of cytarabine, there was 49% and 42% inhibition of proliferation of conjunctival fibroblasts compared with the control respectively. Therefore, the authors concluded that the liposome encapsulated cytarabine is effective on inhibition of proliferation of conjunctival fibroblasts and reduces the frequencies of subconjunctival injection compared with the cytarabine itself.
