Abstract This article presents an approach centered on a modification of the Failure Modes and Effects Analysis Method (FMEA) for risk management concerning geotechnical structures during the hydraulic circuit filling process within a hydroelectric power plant. In this work, the conventional FMEA method, typically employed in various projects and processes, was adapted through the development of specific classification criteria. The primary objective was to enhance the applicability of this method to geotechnical structures during the filling procedure. The validity of this method was confirmed through its application in a case study. This analysis suggests that the newly devised scoring tables have streamlined the risk analysis process by reducing the number of classification categories and adopting a color scale. In addition to their role in classifying failure modes, these tables also serve as a guide for mitigating the risks associated with the filling procedure. The appropriate course of action is determined based on the specific aspects presented in the analyzed geotechnical model. It is our belief that the insights generated by this research will offer valuable support to technical professionals responsible for hydraulic circuit filling in hydroelectric projects. This support aims to enhance the safety of this activity by minimizing the severity of failures and increasing the probability of their detection.

Cet article a pour but de passer en revue l’origine du concept des psychoses cycloïdes, sa psychopathologie et son évolution. Une analyse de la littérature a permis aux auteurs de déterminer la validité nosologique de ce concept, ainsi que sa délimitation actuelle et son utilité future pour la psychiatrie.

This paper intends to review the origin of the concept of cycloid psychoses, its psychopathology and its evolution. By analyzing the literature, the authors seek to delineate the nosological validity of this concept, as well as its current delimitation and its future utility in psychiatry.

Dieser Artikel hat zum Zweck, den Ursprung des Konzepts der Zykloiden Psychosen, seine Psychopathologie und seine Entwicklung zu untersuchen. Anhand einer Literaturanalyse versuchen die Autoren, die nosologische Gültigkeit dieses Konzepts, seine aktuelle Abgrenzung und seinen zukünftigen Nutzen für die Psychiatrie zu erörtern.

Os autores apresentam um caso de hemangioendotelioma epitelioide (HEE) primário do pulmão num doente de 51 anos, sexo masculino, que iniciou queixas de tosse seca, seguida de sintomas constitucionais e dispneia. Apôs realização de alguns exames complementares de diagnostico, que incluiram biopsia cirúrgica, foi considerada a hipótese de tuberculose pulmonar e iniciou antibacilares, que manteve durante três semanas. Por agravamento clínico e imagiologico, foi feita revisão do caso e estudo imunoistoquimico dos tecidos pulmonares biopsados e concluiu-se estar perante um HEE de alto grau/angiossarcoma do pulmão. Iniciou quimioterapia com carboplatina, etoposido e bevacizumab, com ligeira melhoria. Faleceu sete meses após o aparecimento dos primeiros sintomas e sete semanas apos o diagnostico definitivo. Os autores pretendem realçar a raridade desta neoplasia pulmonar, a importância da suspeição clínica e as dificuldades no diagnostico e tratamento, e salientar os potenciais benefícios da utilização de um fármaco antiangiogenico.

The authors report a case of a primary pulmonary epithelioid haemangioendothelioma (EHE) in a 51 year-old man, a mechanic, who complained of a dry cough followed by constitutional symptoms and dyspnoea. Patient underwent a series of diagnostic exams including surgical biopsy and pulmonary tuberculosis was diagnosed. He was prescribed tuberculosis drugs for three weeks. Following clinical and imagiology deterioration, the case was reviewed by pathologists who concluded the pulmonary biopsy revealed an intermediate/high grade pulmonary EHE/angiosarcoma. The patient underwent three cycles of chemotherapy with carboplatin, etoposide and bevacizumab with no complications. He died seven months after onset of symptoms and seven weeks after definitive diagnosis. The authors wish to highlight the rarity of this pulmonary neoplasm and the importance of clinical suspicion, and the diagnosis and treatment difficulties in addition to the potential benefits of antiangiogenic drugs.
