Defying Standard Criteria for Digital Replantation: A Case Series

INTRODUCTION: There is much controversy regarding the current indications and contraindications for digital replantation. PRESENTATION OF CASE: Three patients with absolute contraindications for digital replantation according to classical criteria are presented (Case 1: multilevel amputation of the hand and fingers; Case 3: avulsion of the thumb; Case 4: index amputation proximal to the insertion of the flexor digitorum superficialis). In addition a patient with a very distal digital amputation (Case 2), whose indication for replantation is controversial is also presented. In all cases, the patients were replanted and showed good functional and aesthetical results. DISCUSSION: Most authors advocate that the classical indications for replantation have been validated by experience, are predicated on the potential for long-term function, and should be followed in most if not all cases. However, some surgeons have been adopting a more liberal attitude with good results. CONCLUSION: The clinical cases presented in this paper suggest that the standard criteria for digital replantation should not be followed rigidly but instead should be regarded as a general guide.

Conexão Venosa Pulmonar Anómala. Estudo de Vinte e Quatro Crianças com Angiografia de Subtracção Digital

Objectivo: Avaliar a acuidade da angiografia de subtracção digital (ASD) no diagnóstico morfológico da conexão venosa pulmonar anómala (CVPA) em crianças. Concepção do estudo: Estudo prospectivo de doentes consecutivos entre Janeiro de 1989 e Julho de 1992. Tipo de Atendimento: Serviço de Cardiologia Pediátrica de um Hospital Central. População: Vinte e quatro doentes com CVPA. Métodos: Todos os doentes fizeram avaliação clínica e ecocardiográfica completa (modo M, bidimensional e Doppler) antes da realização do exame hemodinâmico. Em todos os casos se fizeram, de modo sistemático, injecções selectivas de contraste de baixa osmolaridade (0,5-1 ml/kg; dose total <6 mi/kg) no tronco e ramos da artéria pulmonar com registo em angiografia com subtracção digital (ASD). As imagens colhidas foram trabalhadas, selecciona das e armazenadas em video-cassetes e películas fotográficas (câmara multiformato). Resultados: Dezasseis doentes tinham CVPA total (CVPAT): onze à veia cava superior (VCS), dois ao seio coronário e três infradiafragmáticos (dois à veia cava inferior (VCI) e um à veia porta). Oito crianças tinham CVPA parcial (CVPAP): três à VCS, uma à aurícula direita (AD), três à VCI (síndroma da cimitarra) e num caso a CVPA era mista. Em oito doentes (seis com CVPAT e dois com CVPAP), a ASD contribuiu significativamente para o diagnóstico final tendo completado ou corrigido a informação obtida por ecocardiografia. Nos dezoito doentes submetidos a cirurgia cardíaca foi confirmado o diagnóstico obtido por ASD. Conclusões: A ASD é um método muito útil para o diagnóstico anatómico de doentes com CVPA. Na nossa experiência foi particularmente informativa a análise de registos em «video». A ASD está indicada nos casos em que os achados clínicos e ecocardiográficos não sejam típicos.

Improving Influenza Surveillance in Portuguese Preschool Children by Parents' Report

Influenza surveillance is usually based on nationally organized sentinel networks of physicians and on hospital reports. This study aimed to test a different report system, based on parents' phone contact to the research team and in home collection of samples by a dedicated team. The identification of influenza and other respiratory viruses in children who attended a Hospital Emergency Department was also recorded. Real-time PCR and reverse transcription PCR were performed for influenza A and B, parainfluenza 1-4, adenovirus, human metapneumovirus, respiratory syncytial virus A and B, rhinovirus, enterovirus, group 1 coronaviruses, group 2 coronaviruses, and human bocavirus. One hundred children were included, 64 from the day care centers and 36 from the Hospital. Overall, 79 samples were positive for at least one respiratory virus. Influenza A (H3) was the virus most frequently detected: 25 cases, 20 of these in children under 5 years of age (ten from day care centers and ten who went to the hospital) which was higher than those reported by the National Influenza Surveillance Programme for this age. CONCLUSION: The results obtained in this study suggest that a surveillance system based on parents' reports could complement the implanted system of the National Influenza Surveillance Programme.
