Hodgkin Lymphoma (HL) is a lymphoid tumour that represents about 1% of all neoplasms occurring worldwide. HLis the most treatable of childhood malignancies. The etiology of HLis unknown. However, increase risk has been reported in males, with autoimmune diseases, poor socioeconomic status, increased family size, Ebstein Barr Virus (EBV) exposure, congenital or acquired immunodeficiency and those with a family history of HL. Familial HLis rare. The risk of developing HLis increased six times in the siblings of the affected patients...

Hemophagocytic lymphohistiocytosis (HLH) is not always suspected at the time of presentation. It is often mistaken for other diagnoses; complicated by the fact that it is often associated with an inciting event that has significant overlap. Kawasaki disease, along with other disorders, such as Ebstein Barr Virus infection, are conditions that may lead HLH. Our patient had a presentation that was consistent with Kawasaki disease on initial presentation, however subsequently met the diagnostic criteria of HLH...

Hemophagocytic lymphohistiocytosis (HLH) is a rare and severe syndrome usually associated with a cytotoxicity deficiency, which leads to an excess of immune response driven by activated macrophages and cytotoxic T cells. In children, HLH can be genetic, as part of a familial lymphohistiocytosis, or secondary: the most frequent causes are systemic-onset juvenile idiopathic arthritis, hematological malignancies, and severe infections, especially with Ebstein-Barr virus or leishmaniosis. We report on the case of a 3-year-old girl with no past medical history, who presented inaugural Pseudomonas aeruginosa maxillary osteitis, with secondary HLH...

BACKGROUND: Extranodal natural killer T-cell lymphoma (NKTCL), nasal type, is a rare and aggressive malignancy that occurs predominantly in Asian and Latin American populations. Although Epstein-Barr virus infection is a known risk factor, other risk factors and the pathogenesis of NKTCL are not well understood. We aimed to identify common genetic variants affecting individual risk of NKTCL. METHODS: We did a genome-wide association study of 189 patients with extranodal NKTCL, nasal type (WHO classification criteria; cases) and 957 controls from Guangdong province, southern China...

Systemic onset juvenile idiopathic arthritis (SoJIA) is characterized by arthritis, fever and visceral organ involvement including hepatosplenomegaly, lympadenopathy and serositis. This is a case of SoJIA misdiagnosed as Kawasaki disease (KD) and developed machrophage activation syndrome (MAS) secondary to Ebstein-Barr virus (EBV) infection. It is presented to point out the conditions that may come along. First of all, SoJIA should be kept in mind while making the differential diagnosis of coronary arterial ectasias and dilatations usually seen in vasculitic diseases like KD...

BACKGROUND Ebstein-Barr virus (EBV) plays a critical role in nasopharynx cancer, which can be effectively monitored by serum levels of early antigen antibody (EA-IgA) and viral capsid antigen antibody (VCA-IgA). This study explored the diagnostic value of combined assays of sialic acid (SA), EA-IgA, and VCA-IgA via the expressional assay. MATERIAL AND METHODS A total of 42 nasopharynx cancer patients and 42 benign rhinitis and healthy controls were recruited in this study. Serum EA-IgA and VCA-IgA were tested by enzyme-linked immunosorbent assay (ELISA) and enzymatic assay of serum SA...

BACKGROUND: Nasopharyngeal carcinoma often occurs in humans in the nasopharyngeal epithelium area. Ebstein-Barr (EB) virus plays a key role in the process of nasopharyngeal carcinoma lesions. Early antigen antibody (EA-IgA) and viral capsid antigen IgA (VCA-IgA) of EB virus detection in serum can effectively monitor the process of nasopharyngeal carcinoma lesions. Serum vascular endothelial growth factor (VEGF) -C and VEGF-D expression detection can reflect the distant metastases ability of human tumor cells...

AIM: Changes in gut microbiota may contribute to NEC, but most studies focus on bacteria. Case reports suggest a link between cytomegalovirus (CMV) or other enteric viruses and NEC, but there are few case series systematically looking at common potential viral causes. We aimed to assess the presence of candidate viruses in blood or stool of a case series of infants with NEC managed in one surgical centre. METHODS: We identified 22 infants diagnosed with NEC (from November 2011 to March 2014): 17 had suitable blood stored, of whom 14 also had suitable stool samples stored...

The array of diagnostic workup for pyrexia of unknown origin (PUO) generally revolves in searching for infections, inflammatory/autoimmune, and endocrine etiologies. A differential diagnosis of fever, hemolytic anemia, and thrombocytopenia can have etiologies varying from infections like malaria, dengue, cytomegalovirus, Ebstein barr virus, Parvovirus, infective endocarditis, to autoimmune disorder (systemic lupus erythromatosis), vasculitis, hemolytic uremic syndrome, thrombotic thrombocytopenic purpura (TTP), autoimmune hemolytic anemia/Evan's syndrome, paroxysmal nocturnal hemoglobinuri (PNH), or drugs...

BACKGROUND: Primary Central Nervous System Lymphomas (PCNSLs) are rare, malignant brain tumors derived from lymphocytes B. Juvenile xanthogranuloma (JXG) is a non-Langerhans histiocytic cell disorder in children which mostly affects the skin. Rare fatalities have been reported in extracutaneous manifestation. Brain magnetic resonance imaging (MRI) is a method of choice in the diagnostics of all neoplastic CNS lesions. Perfusion weighted imaging (PWI) and diffusion weighted imaging (DWI) allow for more detailed analysis of brain tumors including the rate of neoangiogenesis and cellularity...

Hemophagocytic lymphohistiocytosis (HLH) is a syndrome characterized by high fever, maculopapular rash, neurological symptoms, abnormal liver functions and coagulopathy. Primary HLH is due to an underlying genetic abnormality. Secondary HLH are due to an underlying infection, autoimmune disease or malignancy. Secondary HLH due to viral infections are commonly due to the herpes group commonest of which is the Ebstein Barr virus (EBV). We describe two children with virus associated hemophagocytic lymphohistiocytosis (VAHLH) secondary to hepatitis A infection...

BACKGROUND: Various infectious agents like Ebstein Barr Virus (EBV), HTLV-1 and Helicobacter pylori have known as etiologic factors in different sub-types of lymphoma. Although Hepatitis C virus (HCV) has not only been important for its hepatotropism and hepatitis development, but also in recent years its association with some forms of non- Hodgkin's lymphoma (NHL), especially B cell NHL, has reported.In some countries, the rate of B cell NHL development in HCV infected patients was four times more than general population, and then association between HCV infection and B-NHL has proposed in many studies...

Gianotti-Crosti syndrome (GCS) is a self-limiting, mostly childhood-appearing, cutaneous eruption with characteristic symmetric areal distribution. The original cases, described by Gianotti in 1955, were associated with hepatitis B virus infection, but other viral and bacterial infections, as well as immunizations, have been implied in etiology of this condition. Adult cases are rare and have been reported almost exclusively in women. We present the case of a 20-year-old Caucasian man who had typical clinical presentation: monomorphic pale, pink-to-flesh - colored or erythematous papules and papulovesicles localized symmetrically over the extensor surfaces of the extremities, buttocks and the face; some lesions were detected on knees, elbows and palms, as well...

Nasal type of Natural Killer (NK)/T cell lymphoma manifests in the nasal cavity. Approximately 95% of them are associated with EBV(Ebstein Barr Virus) with a strong predilection for the Asian population. It has certain systemic and localized symptoms which aid in diagnosis of the condition. However, the histological criteria is pivotal in confirming the diagnosis as well as aiding in confirming the association of EBV. Nasal type of NK/T cell lymphoma has a guarded prognosis. Treatment plan include radiotherapy with concurrent chemotherapy...

Multiple sclerosis (MS) is an inflammatory and neurodegenerative disease characterized with autoimmune response against myelin proteins and progressive axonal loss. The heterogeneity of the clinical course and low concordance rates in monozygotic twins have indicated the involvement of complex heritable and environmental factors in MS pathogenesis. MS is more often transmitted to the next generation by mothers than fathers suggesting an epigenetic influence. One of the possible reasons of this parent-of-origin effect might be the human leukocyte antigen-DRB1*15 allele, which is the major risk factor for MS and regulated by epigenetic mechanisms such as DNA methylation and histone deacetylation...
