Ebstein Barr

A 27 year old man developed neuralgic amyotrophy of the right upper limb 5 weeks after an acute febrile illness which was proven serologically to be caused by Ebstein-Barr virus. The weakness developed in a limb that had been used to perform heavy manual labour. A parallel with a similar phenomenon described in association with paralytic poliomyelitis is noted.-

Renal transplantation is the treatment of choice for children with end-stage renal disease. The aim of this study was to evaluate retrospectively of our 37 pediatric renal allograft recipients, including 20 boys and 17 girls from July 2007 to August 2012. The overall mean age at transplantation was 12.16 ± 4.25 years. Three patients (8.1%) were transplanted preemptively; two were ABO-incompatible transplantations. The majority of recipients received living donor grafts (81%). The mean duration of follow-up was 25...

Encephalitis is an uncommon neurological complication of Ebstein-Barr virus (EBV) infection and usually presents with confusion, decreased level of consciousness, fever, epileptic seizure, emotional instability and chorea. We present a patient with EBV encephalitis, characterised by nominal dysphasia, euphoria and personality changes.

Scleredema adultorum is a rare condition characterised by progressive collagen and mucin deposition in the skin. While the aetiology has not been clearly delineated, the condition is often associated with common infections. The current report describes a previously healthy 16-year-old boy who presented with 3 weeks of progressive neck swelling and skin induration. He had evidence of both active streptococcal and Ebstein-Barr virus (EBV) infections. Skin biopsy confirmed the diagnosis of scleredema. The patient was treated for his streptococcal infection, but otherwise managed conservatively...

Drug allergy describes clinical adverse reactions that are proved or presumed to be immunologically based. Allergic drug reactions do not resemble pharmacologic actions of the incriminated drug and may occur at fractions of what would be the therapeutic dosage. Allergic drug reactions are unpredictable; nevertheless, there is increased risk of drug hypersensitivity in (1) patients with cystic fibrosis who receive antibiotics; (2) patients with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) who receive trimethoprim/sulfamethoxazole of if HLA-B*5701(+) and receive the antiretroviral agent, abacavir; (3) other genetically susceptible populations such as Han-Chinese who are HLA-B*1502(+) who develop Stevens-Johnson syndrome and toxic epidermal necrolysis from carbamazepine or if HLA-B*5801(+) are at increased risk for such reactions from allopurinol; and (4) patients with a history of previous compatible allergic reaction to the same medication, similar class, or potentially unrelated medication...

Ebstein-Barr Virus (EBV)-related lymphoproliferative disorders primarily occur in the setting of immunosuppression, most commonly after solid organ transplantation. The frequency depends on the degree of immunosuppression and the specific organ transplanted, but can be as high as 3–9% in heart or lung transplant patients. Less frequent outside of the transplant setting, EBV-related lymphoproliferative disorders classified as other iatrogenic immunodeficiency associated lymphoproliferative disorders in the WHO Classification, which are different than iatrogenically related lymphomas supervening on hematological malignancies, have been associated with other immunosuppressive therapies such as 6-Mercaptopurine, azathioprine, or alemtuzumab...

INTRODUCTION: Viral myocarditis can lead to heart failure that is refractory to medication. In these cases, a ventricular assist device is a good therapeutic option that can be used as a bridge to transplantation or recovery. We describe the first case in Portugal of recovery with ventricular assistance after severe myocarditis. CASE REPORT: A five-year-old boy with no previous cardiac disease presented with severe viral myocarditis, refractory to medical treatment, with positive serology for parvovirus B19 and Ebstein-Barr virus...

INTRODUCTION: Haemophagocytic lymphohistiocytosis (HLH) is a disorder characterised by long-standing fever, splenomegaly and bicytopoenia or pancytopoenia. Lymphadenopathy, jaundice and neurological symptoms mayalsooccur. HLH may ensue in various forms of innate or acquired immunodeficiency with impaired cytotoxic lymphocyte function resulting in excessive macrophage activation. OBJECTIVE: To describe and analyse clinical characteristics of patients treated for HLH at the University Children's Hospital of Belgrade from August 2000 to August 2010...

Tricuspid valve malformation is a rare congenital heart disease. Prenatal diagnosis of Ebstein's anomaly (EA) and tricuspid valve dysplasia (TVD) is associated with high mortality. There are conflicting reports concerning accurate prognostication after diagnosis in utero. The aim of our study was to assess prognostic factors based on our experience. We reviewed 37 fetuses between 1984 and June 2010 comprising 26 cases of EA and 11 cases of TVD. There were 10 terminations, 5 intrauterine deaths, 8 neonatal deaths, and 14 survivors...

BACKGROUND: Cutaneous lymphoepithelioma-like carcinoma (cutaneous LELC) is an extremely rare malignant neoplasm with unclear histogenesis. Its histopathologic features are like those of lymphoepithelioma-like carcinoma occurring in the nasopharynx and in visceral organs especially salivary glands. MATERIAL AND METHOD: The authors reported on one male and two female patients of cutaneous LELC with immunohistochemical and electron microscopic study. All patients were of old age...

Anabolic androgenic steroids (AAS) are the main class of doping agents and their consumption produces adverse effects involving several organs and systems. Three cases of sudden cardiac death (SCD) and one of death due to congestive heart failure of previously healthy athletes who were AAS users are herein reported. Concentric cardiac hypertrophy with focal fibrosis (one case), dilated cardiomyopathy with patchy myocyte death (two cases) and eosinophilic myocarditis (one case) were observed and most probably relate to the final event...

Epstein-Barr virus infectious mononucleosis can cause transient immune deficiency which may predispose to reactivation of latent herpes simplex virus (HSV) infection in the immunocompetent host. We report the case of a 15-year-old male who presented with severe odynophagia and herpes labialis during the course of Epstein-Barr virus infectious mononucleosis that had been diagnosed ten days before. Esophagoscopy revealed extensive ulcerations with distinct borders and whitish exudates at the mid and distal esophagus...

The objective of this study was to find any association of extrahepatic biliary atresia (EHBA) with a possible infectious etiology. Infants diagnosed to have EHBA were tested by blood PCR for cytomegalovirus (CMV), Ebstein-Barr virus, HBsAg, anti-HCV and IgM antibodies for CMV, toxoplasma, rubella, and herpes infections. Thirty-three infants of EHBA were included in the study, male 22, median age when diagnosed 2.5 months (range 1.0-5.0 months). On examination pallor, oedema and hepatosplenomegaly were seen in all and ascites and microcephaly in 19 (57...

Viral infections and graft-versus-host disease (GVHD) render an impact on both the clinical and immunological recovery following allogeneic hematopoietic stem cell transplantation (HSCT). We studied the recuperation of the immune defence after transplant in the paediatric setting and assessed the impact of early (<100 days post-HSCT) viral [cytomegalovirus (CMV), Ebstein-Barr virus (EBV) and adenovirus] reactivations/infections and GVHD. Fifty-one paediatric recipients of HSCT were enrolled. T cell recovery was evaluated on lymphocyte subpopulations using flow cytometry and functionally by measuring T cell excision circles (TRECs) and through the analysis of T lymphocyte responses to mitogens...

Esophageal involvement by extranodal natural killer (NK)/T cell lymphoma, nasal type, is rare. As a result, esophageal symptoms in these patients might at first be thought to originate from a benign condition, such as viral esophagitis. It is important to note, however, that benign conditions may mask esophageal involvement by lymphoma. Until now, there has been no report documenting esophageal involvement by lymphoma mimicking viral esophagitis in an extranodal NK/T cell lymphoma patient undergoing active treatment...

In a 19-year-old severely autistic and mentally retarded girl, a balanced de novo t(14;21)(q21.1;p11.2) translocation was found in addition to a de novo 2.6-Mb 2q31.1 deletion containing 15 protein-encoding genes. To investigate if the translocation might contribute to developmental stagnation at the age of 2 years with later regression of skills, i.e. a more severe phenotype than expected from the 2q31.1 deletion, the epigenetic status and expression of genes proximal and distal to the 14q21.1 breakpoint were investigated in Ebstein Barr Virus-transformed lymphoblast and primary skin fibroblast cells...

In this case-report a case of severe fetal anemia of unknown origin is presented. Diagnosis of fetal anemia was made at 24 weeks of gestational age, when fetal ascites was identified. Doppler sonography of medium cerebral artery showed a high systolic speed velocity (ACM-PSV), of 65 cm/s (>1.55 MoM). This value predicts a severe fetal anemia. Funicolocentesis confirmed hyporegenerative anemia, low reticulocytosis and low erythroblastosis. A fetal transfusion was performed. At birth anemia was still present and the baby presented blueberry muffin and liver erythropoietic foci...
