Propuesta de guía de implementación de un sistema de gestión de seguridad y salud en el trabajo basado en la norma INTE/ISO 45001:2018 para la empresa Corporación de Profesionales en Ingeniería S.A.

Proyecto de Graduación (Licenciatura en Ingeniería en Seguridad Laboral e Higiene Ambiental) Instituto Tecnológico de Costa Rica, Escuela de Ingeniería en Seguridad Laboral e Higiene Ambiental, 2019.The project was carried out in the company Corporación de Profesionales en Ingeniería S.A., dedicated to the construction sector. The objective was to develop a guide for the implementation of a Work Health and Safety Management System based on the INTE/ISO 45001: 2018 standard. For the development of the proposal, the current management of the company was initially analyzed through a review of documents, the application of the checklist based on NTP 308, a survey for managers and another for collaborators. Subsequently, the analysis of the organization's context, internal and external, is carried out through an analysis of PESTEL and finally the information is synthesized in a SWOT. Then an assessment of risks and opportunities is carried out by means of a non-participatory observation and the guidelines for the verification of conditions in the construction sector are applied in the projects to be subsequently evaluated through the risk evaluation matrix according to the standard INTE 31-06-07: 2011. After analyzing the tools, results were obtained such as the absence of a formal written commitment from management, the lack of documentation and the presence of important risks for workers in the activities they carry out. This is summarized in the current management of the company in health and safety has great opportunities for improvement and shows the need for immediate intervention measures to improve the situation, which leads to the implementation guide of a health and safety system in work to improve the working conditions of the organization.El proyecto se realizó en la empresa Corporación de Profesionales en Ingeniería S.A., dedicada al sector construcción.

Luego se realiza una evaluación de riesgos y oportunidades por medio de una observación no participativa y se aplica en los proyectos la guía de verificación de condiciones en el sector construcción para posteriormente ser valorados mediante la matriz de evaluación de riesgos según la norma INTE 31-06-07:2011. Tras el análisis de las herramientas se obtuvieron resultados como la ausencia de un compromiso formal por escrito de parte de la dirección, la inexistencia de documentación y la presencia de riesgos importantes para los trabajadores en las actividades que desarrollan. Esto se sintetiza en que la gestión actual de la empresa en salud y seguridad tiene grandes oportunidades de mejora y muestra la necesidad de medidas de intervención inmediatas para mejorar la situación, lo que conlleva a la guía de implementación de un sistema de salud y seguridad en el trabajo para mejorar las condiciones laborales de la organización

Persistent sciatalgia due to a wandering bipolar forceps tip after posterior lumbar stabilization: A case report

WOS: 000384801600009There are several reports in the literature about the retained surgical materials as a cause of radicular pain or sensory impairment after spinal surgery. We report a patient with a persistent radicular pain in the distribution of left S1 nerve dermatome following lumbar stabilization surgery. Retained bipolar forceps tip has not been reported previously in the literature as a cause of sciatalgia after posterior lumbar surgery

Primary Multiple Cerebral Hydatid Disease: Still Symptomatic Despite Pathologically Confirmed Death of the Cyst

Hydatid disease is a life-threatening parasitic infestation caused by Echinococcus granulosus. Infection with E. granulosus typically results in the formation of hydatid cysts in liver, lungs, kidney and spleen. Majority of the intracranial cysts are secondary and solitary. Multiple primary cerebral cysts are uncommon. Surgical and medical management of a 14-year-old boy with multiple primary hydatid cysts are presented. 14 cysts, which were symptomatic due to their mass effect, were surgically removed, whereas a deep-seated asymptomatic cyst was followed-up with medical treatment. Despite proper antibiotic regimen the patient was admitted with epileptic seizures six months later. The deep-seated lesion was also surgically removed. Intraoperative observations and pathological examination demonstrated different characteristics, with pericystic gliosis, gel-like cyst content and death scolices within the cavity. In addition to the fact, that the presented case is an additional example for the rare primary multiple cerebral hydatid cysts, to our knowledge it is the first case of a dead cerebral hydatid cyst, causing symptoms despite effective medical treatment

Doxorubicin for prevention of epineurial fibrosis in a rat sciatic nerve model: outcome based on gross postsurgical, histopathological, and ultrastructural findings Laboratory investigation

Object. Epineural fibrosis may complicate peripheral nerve surgeries and currently is considered as one of the main factors responsible for failed surgeries. The authors investigated the postoperative antiscarring effects of topically applied doxorubicin (DXR) on rat sciatic nerves

The axon protective effects of syringic acid on ischemia/ereperfusion injury in a rat sciatic nerve model

WOS: 000392042000017PubMed ID: 27593755AIM: In the relevant literature, there is no experimental study that investigated the axon protective effects of syringic acid- a polyphenol compound- with an anti-oxidant capacity on ischemia/reperfusion injury. MATERIAL and METHODS: The rats were randomly divided into four groups: Control group (no medication or surgical procedure), Sham group, Syringic acid group, and Methyprednisolone (MP) Group. lschemia was achieved by abdominal aorta clamping and all animals were sacrificed 24 hours after ischemia. Harvested sciatic nerve segments were investigated histopathologically and for tissue biochemistry. RESULTS: lschemic fiber degeneration scores were found significantly lower in syringic acid and MP groups than sham group. Additionally, apoptosis-related cysteine peptidase caspase-3 immunostaining scores were lower in syringic acid and MP groups. Biochemically, superoxide dismutase and nuclear respiratory factor 1 values were significantly higher in syringic acid group compared to those of control and sham groups while malondialdehyde levels were significantly lower in the syringic acid group. CONCLUSION: Syringic acid reduces oxidative stress and axonal degeneration in rat sciatic nerve after ischemia/reperfusion injury. Therefore, syringic acid may play a role in the treatment of peripheral nerve injuries due to ischemia/reperfusion

THE MOTION RANGE OF THE CONUS MEDULLARIS MOVEMENT WITH SERIAL MAGNETIC RESONANCE IMAGING IN SUPINE AND PRONE POSITIONS: RESULTS OF FOURTY HEALTHY SUBJECTS

Objective: In this study, using a series of supine and prone positions T1 and T2 with weighted axial and sagittal magnetic resonance imaging, the movement interval of the conus medullaris stimulated by the supine-prone position change was assessed in 40 healthy subjects
