CONCLUSION: Potentially curable forms of myocarditis, like M pneumoniae and CMV, for example, can have an initial disproportionate aggression to the myocardium, by the acute inflammatory reaction, that can by itself make worse the damage to the LV function. In our opinion, the blockade of this process by pulsotherapy with steroids can help in the treatment of these patients. We understand that the different scenario of immunosuppressive treatments for the possible auto immunity of the more chronic forms of the presumably post viral cardiomyopathy has been in dispute in the literature, and has stolen the focus from the truly acute cases.OBJETIVO: Doença sistêmica por citomegalovírus (CMV) com miocardite em pessoas saudáveis é raramente referida na literatura, apesar de em maior número...

Conclusions. EBV-associated IM does not seem to be a risk factor for SLE. The temporal pattern of increased SLE risk in individuals with a negative PB test suggests that some patients who go on to develop SLE may present with unspecific symptoms, for which they may be tested for IM, long in advance of their SLE diagnosis.

Authors: Kanai K, Takashima K, Okuno K, Kato K, Sano H, Kuwamoto S, Higaki H, Nagata K, Sugihara H, Kato M, Murakami I, Hayashi K Most humans become lifelong carriers of Epstein-Barr virus (EBV) by adulthood. Primary EBV infection in adolescents causes in one to two-third of cases infectious mononucleosis. EBV infection is associated with various diseases, neoplasms and hematological disorders. Recently we reported that EBV can infect rabbits frequently by intravenous, intranasal or/and peroral inoculation, which caused primary EBV infection in rabbits with heterogeneous host reactions. Here we presented follow up data that of six primary EBV-infected rabbits out of seven inoculated intravenously with EBV, two out of six EBV-infected rabbits showed lifetime EBV infection.

We describe the case of a 22-month-old male child, who appeared in the emergency room of Hospital de Clínicas de Porto Alegre because of fever and with a previous diagnosis of mononucleosis made at another Institution. The clinical presentation together with laboratory findings allowed the correct diagnosis. The patient was treated with chemotherapy and underwent hematopoietic stem cell transplantation.

DISCUSSION: Dacryocystitis is a rare and little documented complication of EBV infection. Its acute evolution to orbital cellulitis is possible and potentially severe. Its physiopathology is specific. Patients are initially free of chronic stenosis and epiphora, which express acute obstruction of the lachrymal sac due to general lymphoid hyperplasia.

X-linked lymphoproliferative syndrome (XLP) is a rare immunodeficiency with extreme vulnerability to Epstein-Barr virus (EBV) infection. It presents with fatal infectious mononucleosis, lymphoproliferative disorder, or dysgammaglobulinemia. The majority of affected males have mutations in the SH2D1A/SLAM-associated protein (SAP) gene. We previously generated an antihuman SAP monoclonal antibody (KST-3) for a flow cytometric assay and described the activation of T cells to be necessary for the flow cytometric assessment of the SAP expression using an FITC-conjugated secondary antibody.Between 2005 and 2008, we recruited 23 male patients with suspected XLP, including mainly EBV-associated hemophagocytic lymphohistiocytosis (HLH), and attempted to evaluate SAP expression in fresh lymphoid cel...

Conclusion: Immunophenotyping including the combination of the fractions of HLA-DR expressing T cell subpopulations with the level of CD40 on monocytes produces an informative pattern, differentiating between bacterial origin, viral origin and systemic autoimmunity. Furthermore, it provides some indication of a subacute bacterial infection, such as borreliosis or tuberculosis. This flow cytometric method is suitable for clinical diagnostic laboratories, and may help in the assessment of patients with uncharacteristic inflammatory symptoms.

Authors: Fachiroh J, Stevens SJ, Haryana SM, Middeldorp JM Current single Epstein-Barr virus (EBV) markers fail to reach 100% sensitivity for serodiagnosis of acute and malignant diseases associated with EBV infection. Previous study had identified immunodominant epitopes of VCA-p40 and VCA-p18, and indicated that these two VCA antigens may have diagnostic value for EBV-related diseases. A recombinant protein of the full length BdRF1 fused to the immunodominant domain of BFRF3 as 6-his tagged protein in E. Coli was developed. The recombinant protein was extracted in 8M urea solution and purified by metal-affinity chromatography yielding a 55kDa product (VCA-p40+18). VCA-p40+18 blot-strips examined for IgM reactivity in infectious mononucleosis samples yielded 100% sensitivity and speci...

Patients share their stories about the long road back to full health after a serious brain injury or illnessA couple of weeks ago, I took a small stepladder into the back garden and climbed a few rungs to fix a light that had stopped working. It doesn't sound much but I glowed with achievement for the rest of the day. Six months earlier, I would have been too unsteady to risk it, and tilting my head to do the repair would have brought on a surge of vertigo and violent sickness. A year ago, I wouldn't even have attempted it – or cared: I was lying on the sofa, intermittently vomiting and being pumped full of industrial-strength antibiotics to see off a mysterious brain infection that had nearly killed me.Last May I was struck down by an abscess on the cerebellum, which controls movement, ...

Lymphoma diagnosis integrates clinical, morphological, immunophenotypical, and molecular genetic features, as shown in WHO classifications of lymphoid malignancies. Diagnosis of lymphoma is challenging. Reactive lesions such as Kikuchi lymphadenitis, infectious mononucleosis, autoimmune lymphoproliferative syndrome, and immunoglobulin G4-related sclerosing disease can be misdiagnosed as lymphomas. Anaplastic large-cell lymphoma variants that are positive for anaplastic lymphoma kinase, classical Hodgkin's lymphoma variants, and infarcted lymphomas might be misdiagnosed as reactive disorders. Difficulties with classification of lymphomas are also encountered, such as the distinction of classical Hodgkin's lymphoma from anaplastic large-cell lymphoma that is negative for anaplastic lymphoma ...

Conclusions Occupational physicians should advise gradual return to work, starting 4 weeks after the onset of the illness, in order to prevent physical deconditioning and prolonged illness. (Source: Occupational Medicine)
