[Acute affection of the thorax in children for pulmonary blastoma]. / Afección aguda del tórax en niños por blastoma pleuropulmonar.

BACKGROUND: In children, acute affectation of the thorax is presented during pleuropulmonary infection, bronchopulmonary malformation and malignant tumors. We had the opportunity to treat patients with malignant tumors in the thorax and we present our findings. CLINICAL CASES: We studied three patients with the diagnosis of pleuropulmonary blastoma. All patients were being treated with surgical resection for the neoplasm and one patient received pneumonectomy. Diagnosis of blastoma was confirmed histologically and one had positive histochemical markers to vimentin and S-100. Only one patient died. CONCLUSIONS: 1. Different cellular types of pleuropulmonary blastoma were confirmed using histochemical markers. 2. The pediatric surgeon facing a case of a child with acute thorax affectation due to pleuropulmonary blastoma must undertake thoracotomy on an urgent basis.

ANTECEDENTES: en los niños, la afección aguda del tórax se manifiesta concomitante con infección pleuropulmonar, malformaciones broncopulmonares y tumores torácicos malignos. Tuvimos la oportunidad de tratar a pacientes con neoplasia maligna, lo que nos motivó a comunicarla. Casos clínicos: se estudian y reportan los casos de tres pacientes con diagnóstico de blastoma pleuropulmonar. Todos se trataron quirúrgicamente mediante resección del tumor en dos pacientes, en uno fue necesaria la neumonectomía. Los estudios histológicos demostraron que se trataba de un blastoma pleuropulmonar con anaplasia y otro resultó positivo para el marcador tumoral de vimentina y S-100. Solo hubo un fallecimiento. CONCLUSIONES: los diferentes tipos celulares que forman el blastoma pleuropulmonar se ratifican con la aplicación de marcadores histoquímicos. Ante un paciente pediátrico con afección aguda del tórax por blastoma pleuropulmonar, el cirujano pediatra tendrá que practicar una toracotomía de urgencia.

[The Mexican Board of Pathology: microscopy examination before and after digital microscopy]. / Consejo Mexicano de Médicos Anatomopatólogos: su examen de microscopia, antes y después de su digitalización.

INTRODUCTION: The examination carried out by the COMMAP for the certification process assessed pathologist formed in dissimilar institutions. In 2007 COMMAP's governing body in turn, decided to digitize it. The purpose of this study is to investigate whether the conversion to virtual slides in the microscopy section, compared with the traditional have had an impact on the scores of the candidates. METHOD: The slides were scanned with high resolution. The virtual microscope is a standard computer screen where there is a program (Aperio Scope Image Viewer) that can display the scanned slides. The results of the microscopy section of the past nine years were compared; two groups were formed: 1) those without digitized examination, and 2) with it. The results were compared by Student t-test and Mann-Whitney. RESULTS: Of a 461 results 240 belonged to the first group and 221 to the second one. On a scale of 1-10, the average scores were 6.6 and 6.8, respectively (p > 0.6 and > 0.5).The minimum and maximum scores were also similar in each group. CONCLUSIONS: According to the results, the digitized exam in the COMMAP's certification process shows no difference between the digitized and the conventional versions.
