소아에서 매우 드문 질환으로 알려진 호산구성 근막염은 근막의 염증과 말초혈액에서 호산구 증가가 특징인 질환이며 면역학적 이상이 그 원인으로 지목되고 있다. EBV는 숙주의 면역기전에 변화를 일으켜 여러 가지 질환을 유발하는 것으로 알려져 있어 호산구성 근막염을 일으킬 수 있는 선행인자가 될 수 있음을 추정할 수 있다. 이에 저자들은 22개월 남아에서 EBV 감염과 연관하여 발생한 호산구성 근막염 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Infection-induced acute hepatitis complicated with acute pancreatitis is associated with hepatitis A virus, hepatitis B virus or hepatitis E virus. Although rare, Epstein-Barr virus (EBV) infection should be considered also in the differential diagnosis if the patient has acute hepatitis combined with pancreatitis. We report a case of EBV infection with cholestatic hepatitis and pancreatitis with review of literature. An 11-year-old female was admitted due to 1-day history of abdominal pain and vomiting without any clinical symptoms of infectious mononucleosis. Diagnosis of reactivated EBV infection was made by the positive result of viral capsid antigen (VCA) IgM, VCA IgG, Epstein-Barr nuclear antigen and heterophile antibody test. We performed serologic tests and magnetic resonance cholangiopancreatography to exclude other viral or bacterial infection, autoimmune disorder, and structural problems. The patient's symptoms recovered rapidly and blood chemistry returned to normal with conservative treatment similar to previously reported cases.

Epstein-Barr virus(EBV) is associated with a wide spectrum of benign and malignant disorders including leukoplakia, Hodgkln's lymphoma, central nervous system lymphoma, peripheral T cell lymphoma and nasopharyngeal undifferentiated carcinoma. There are several distinctive aspects of biology of the virus that are important in investigation of virus in clinical specimens. The abundant expression of the EBER mRNA transcripts makes possible the sensitive detection of latent expression in EBV-associated tumors. Although there has been a dramatic increased interest in the direct characterization of EBV in clinical specimens, there have been few studios about the effective and reliable positive controls in performing in situ hybridization technique for EBV, especially on paraffin-em bedded tissue. We applied Burkitts lymphoma ceil line as positive control in EBV in situ hydridization using Oncor Kit. The cell block of Burkitt lymphoma cell line(CCL85 EB-3) showed strong and specific positivity for EBER in situ in nuclei of EBV infected cells.

Epstein-Barr virus (EBV) is etiologically associated with a variety of diseases including lymphoproliferative diseases, lymphomas, carcinomas, and autoimmune diseases. Humans are the only natural host of EBV and limited species of new-world monkeys can be infected with the virus in experimental conditions. Small animal models of EBV infection, required for evaluation of novel therapies and vaccines for EBV-associated diseases, have not been available. Recently the development of severely immunodeficient mouse strains enabled production of humanized mice in which human immune system components are reconstituted and express their normal functions. Humanized mice can serve as infection models for human-specific viruses such as EBV that target cells of the immune system. This review summarizes recent studies by the author's group addressing reproduction of EBV infection and pathogenesis in humanized mice.

Infectious mononucleosis is Epstein-Barr virus (EBV) inducing a self-limiting clinical syndrome characterized by fever, sore throat, hepatosplenomegaly, and generalized lymphadenopathy. Gastrointestinal symptoms of EBV infection are nonspecific and occur rarely. EBV inducing acute gastrointestinal pathology is poorly recognized without suspicion. Careful consideration is needed to diagnose gastric involvement of EBV infection including gastric lymphoma, gastric cancer, and gastritis. A few recent cases of gastritis associated with EBV infection have been reported in adolescents and adults. However, there is no report of EBV-associated gastritis in early childhood. We experienced a rare case of 4-year-old girl with EBV gastritis confirmed by in situ hybridization.

Primary Epstein-Barr virus (EBV) infection can manifest with a broad spectrum of neurological complications. There are only rare reports of Guillain-$Barr{\acute{e}}$ syndrome (GBS) supervening on meningitis in patients with primary EBV infection. Clear evidence of central nervous system infection makes it difficult for the clinicians to consider a diagnosis of GBS. We present a patient with GBS supervening on meningitis in primary EBV infection.

중추신경계의 침범을 동반한 Epstein-Barr 바이러스 관련 혈구포식 림프조직구증은 조혈모세포이식을 시행하지 않으면 예후가 좋지 않다. 또한, 고식적인 강도의 전처치시 이식관련 사망률이 높다. 따라서 저자들은 진행성 중추신경계 침범을 보인 Epstein-Barr 바이러스 관련 혈구포식 림프조직구증 2례에서 저강도 전처치와 rituximab 후 타인 조혈모세포이식을 시행하여 치료하였기에 이를 보고하고자 한다.

Background: The presence of Epstein-Barr virus (EBV) in Non-Hodgkin's lymphoma can be identified by immunohistochemistry for detection of EBV latent membrane protein (LMP). The role of EBV as an etiologic agent in the development of non-Hodgkin lymphoma has been supported by detection of high levels of latent membrane protein 1 (LMP-1) expression in tumors. However, no study has been conducted in a Pakistani population up till now to determine the frequency of Epstein-Barr virus positivity. The objective of our study was to determine a value for non-Hodgkin lymphoma patients using EBV LMP-1 immunostaining in our institution. Materials and Methods: This study was carried out at the Department of Histopathology, Armed Forces Institute of Pathology (AFIP), Pakistan from December 2011 to December 2012. It was a cross sectional study. A total of 71 patients who were diagnosed with various subtypes of NHL after histological and EBV LMP-1 immunohistochemical evaluation were studied. Sampling technique was non-probability purposive. Statistical analysis was achieved using SPSS version 17.0. Mean and SD were calculated for quantitative variables like patient age. Frequencies and percentages were calculated for qualitative variables like subgroup of NHL, results outcome of IHC for EBV and gender distribution. Results: Mean age of the patients was $53.6{\pm}16$ years (Mean${\pm}$SD). A total of 50 (70.4%) were male and 21 (29.6%) were female. Some 9 (12.7%) out of 71 cases were positive for EBV-LMP-1 immunostaining, 2 (22.2%) follicular lymphoma cases, 1 (11.1%) case of T-cell lymphoblastic lymphoma, 4 (44.4%) cases of diffuse large B cell lymphomas, 1 (11.1%) mantle cell lymphoma and 1 (11.1%) angioimmunoblastic T cell lymphoma case. Conclusion: In our study, frequency of EBV in NHL is 12.7% and is mostly seen in diffuse large B cell lymphoma. This requires further evaluation to find out whether this positivity is due to co-infection or has a role in pathogenesis.

The results of this study intended to clarify the apoptotic effects of curcumin on Epstein-Barr virus transformed human B lymphoma (EBV-B) cells are summarized as follows: It was found that curcumin induced endoplasmic reticulum(ER) stress as well as apoptotic cell death in EBV-B cells, although the magnitude of action was insignificant. When EBV-B cells activated by pokeweed mitogen (PWM) were treated with the same concentrations of curcumin, it was found that higher ER stress (GRP78, P-PERK, XBP-1, ATF6, and CHOP expressed) increased unfold protein response (UPR) and thus, apoptosis attributed to ER stress, compared to non-activated EBV-B cells In conclusion, it is expected that curcumin will play an important role for leukemia treatment.
