EBV+ cutaneous B-cell lymphoproliferation of the leg in an elderly patient with mycosis fungoides and methotrexate treatment.

A 77-year-old man with a 5-year history of mycosis fungoides (MF) who had received several lines of therapy, including intravenous courses of Methotrexate (MTX) for the past 2 years, went on to develop several ulcerated cutaneous nodules on the left leg. Biopsy revealed diffuse sheets of EBV-positive large B cells (CD20+ CD30 ± IgM Lambda), with an angiocentric distribution and a monoclonal IGH gene rearrangement. Although the pathological features were diagnostic for an EBV-positive diffuse large B-cell lymphoma (DLBCL), several possibilities could be considered for assignment to a specific entity: EBV-positive DLBCL of the elderly, methotrexate-induced lymphoproliferative disorder (LPD), lymphomatoid granulomatosis, or the more recently described EBV-positive mucocutaneous ulcer. The development of EBV+ lymphoproliferations has been reported in two other patients with MF under MTX, and occurred as skin lesions of the leg in one of these and in the current case, which may question the relatedness to primary cutaneous DLCBL, leg-type.

UM ESTUDO COMPARATIVO ENTRE OS INSTRUMENTOS DE PLANEAMENTO DE UM MUNICIPIO DE BRASIL E UMA AUTARQUIA EM CABO VERDE EM SEUS ASPECTOS ALOCATIVOS FISCAIS E SOCAIS

O presente trabalho descreve de forma lacónica o estudo comparado entre o município de Santa Cruz / Cabo Verde e o município de Borá/ Brasil- São Paulo. O objectivo central que guiou a elaboração deste trabalho, procurou essencialmente analisar através da pesquisa qualitativa da comparação, os instrumentos de planeamento municipal praticados nos dois municípios supra referidos nas áreas fiscais, alocativos e sociais, bem como a busca incessante pela complementaridade. Para efectivar a investigação proposta, apresentou-se primeiramente as questões gerais relacionados à fundamentação teórica necessária para a explicitação dos conteúdos da análise. Na sequência, fez-se uma exposição detalhada dos dados obtidos sobre a execução orçamentária apartir de pesquisa documental realizada no Municipio de Santa Cruz – Cabo Verde e do Municipio de Borá, São Paulo – Brasil. Após a incursão na execução orçamentaria de cada municipio que integrou a pesquisa, fez-se uma comparação entre os dados orçados com as realizadas. Além disso, investigou-se também a fundamentação legal da gestão orçamentária e financeira como meio de dotar o Município de Santa Cruz de mecanismo de controle e planeamento estratégico. Com base na análise, concluiu-se que existem realidades diferentes entre os municípios no que concerne a sua estrutura orçamental, suporte legal e também na forma de alocação dos recursos. Assim, as conclusões e recomendações direccionam o trabalho no sentido de oferecer subsídios para a melhoria do sistema de organização de uma estrutura orçamentária que melhor sirva os dois municípios.

High Specificity of C4d/CD68 Staining for the Diagnosis of Late Antibody-Mediated Rejection in Heart Transplantation.

In heart transplantation (HTx), acute antibody-mediated rejection (AMR) is infrequent but carries high mortality and increased risk of graft vasculopathy. The diagnosis requires evidence of acute graft dysfunction, capillary lesions on endomyocardial biopsy (EMB), and immunopathological criteria of antibodymediated injury. Multiple markers of antibody-mediated injuries have been proposed, but there is ample debate on their usefulness. In kidney transplantation, C4d deposition in peritubular capillaries is a reliable marker of alloantibody-dependant graft injury. In this study, we prospectively screened all EMBs for C4d and CD68 in new HTx recipients, and correlated pathological fi ndings with immunological evidence of donor-specifi c antibodies (DSA) and graft dysfunction. Methods Between Nov 05 and Aug 08, we had 22 HTx, and 17 cases were analysed. All recipients received polyclonal rabbit anti-thymocytes globulin, calcineurin inhibitors, mycophenolate mofetil, and corticosteroids (weaning in 6 -12 months). They had EMB every 1-2 weeks in the fi rst 3 months, and then monthly for 9 months. C4d and CD 68 were assessed by immunochemistry. Echocardiography and DSA assessment or crossmatch (early phase) were realised if C4d or CD68 staining was positive. Results There was 1 early and 1 late AMR. Table 1 C4d and CD68 positive, at least 1 EMB 6 / 17; 35% 1 treated C4d and CD68 positive, at least 2 consecutive EMBs 3 / 17; 17.5% 1 treated C4d and CD68 positive, and graft dysfunction 1 / 17; 6% 1 treated C4d and CD68 positive, with DSA and crossmatch + 1 / 17; 6% 1 treated Table 2 C4d and CD68 positive, at least 1 EMB 1 / 17; 6% 1 treated C4d and CD68 positive, at least 2 consecutive EMBs 1 /17; 6% 1 treated C4d and CD68 positive and graft dysfunction 1 / 17; 6% 1 treated C4d and CD68 positive, and + DSA 1 / 17; 6% 1 treated Conclusion In this single-center experience, C4d / CD68 positive staining was frequent in the early phase and raised the question of false positive cases of AMR. However, these markers showed high specifi city for the diagnosis of AMR in the late phase. Of course these data need to be confi rmed in larger multi-center studies.

Alpha rhythm and hypofrontality in schizophrenia

OBJECTIVE: To reveal the EEG correlates of resting hypofrontality in schizophrenia (SZ). METHOD: We analyzed the whole-head EEG topography in 14 patients compared to 14 matched controls by applying a new parameterization of the multichannel EEG. We used a combination of power measures tuned for regional surface mapping with power measures that allow evaluation of global effects. RESULTS: The SZ-related EEG abnormalities include i) a global decrease in absolute EEG power robustly manifested in the alpha and beta frequency bands, and ii) a relative increase in the alpha power over the prefrontal brain regions against its reduction over the posterior regions. In the alpha band both effects are linked to the SZ symptoms measured with Positive and Negative Symptom Scales and to chronicity. CONCLUSION: As alpha activity is related to regional deactivation, our findings support the concept of hypofrontality in SZ and expose the alpha rhythm as a sensitive indicator of it.
