RESUMO

INTRODUCTION: Identifying effective drugs for Coronavirus disease 2019 (COVID-19) is urgently needed. An efficient approach is to evaluate whether existing approved drugs have anti-SARS-CoV-2 effects. The antiviral properties of lithium salts have been studied for many years. Their anti-inflammatory and immune-potentiating effects result from the inhibition of glycogen synthase kinase-3. AIMS: To obtain pre-clinical evidence on the safety and therapeutic effects of lithium salts in the treatment of COVID-19. RESULTS: Six different concentrations of lithium, ranging 2-12 mmol/L, were evaluated. Lithium inhibited the replication of SARS-CoV-2 virus in a dose-dependent manner with an IC50 value of 4 mmol/L. Lithium-treated wells showed a significantly higher percentage of monolayer conservation than viral control, particularly at concentrations higher than 6 mmol/L, verified through microscopic observation, the neutral red assay, and the determination of N protein in the supernatants of treated wells. Hamsters treated with lithium showed less intense disease with fewer signs. No lithium-related mortality or overt signs of toxicity were observed during the experiment. A trend of decreasing viral load in nasopharyngeal swabs and lungs was observed in treated hamsters compared to controls. CONCLUSIONS: These results provide pre-clinical evidence of the antiviral and immunotherapeutic effects of lithium against SARS-CoV-2, which supports an advance to clinical trials on COVID-19's patients.

RESUMO

Objetivo Comprobar que el marcapasos diafragmático es una forma de soporte respiratorio que puede usarse para facilitar la retirada del respirador volumétrico en pacientes con lesión medular cervical y parálisis diafragmática, mediante su comparación con el respirador volumétrico tradicional. Diseño Análisis retrospectivo de una base de datos prospectiva y de tipo caso-control apareado por edad. Ámbito Unidad de Cuidados Intensivos y Unidad de Cuidados Intermedios Respiratorios del Hospital Nacional de Parapléjicos de Toledo. Pacientes Se han recogido los datos de todos los pacientes dados de alta del hospital con soporte respiratorio permanente mediante respirador volumétrico o marcapasos diafragmático con un periodo de seguimiento de 25 años y se han realizado entrevistas personales para valorar la calidad de vida relacionada con la salud. Para las comparaciones estadísticas se han usado tests de comparaciones y de supervivencia. Intervenciones Cuestionario de calidad de vida. Variables de interés Datos demográficos y clínicos, estancia hospitalaria, mortalidad, readaptación familiar y calidad de vida relacionada con la salud. Resultados Hemos examinado las historias clínicas de 101 pacientes, 37 con marcapasos y 64 con un respirador volumétrico. Nuestros resultados muestran tanto una duración del ingreso en UCI y de la hospitalización como una reintegración familiar sin diferencias significativas, con tendencia a una mayor supervivencia en los pacientes con marcapasos (18,18 frente a 9,67 años por el método de Kaplan-Meier, p<0,001), aunque esta diferencia deja de ser estadísticamente significativa (p=0,06) tras controlar (..)

Objective To verify that the diaphragmatic pacemaker is a form of respiratory support that can be used to replace a volumetric respirator in cervical spinal injury patients with cervical spinal lesion and diaphragmatic paralysis by means of its comparison with the traditional volumetric respirator. Design Retrospective study of a prospective database and age-matched case-control study. Setting Intensive Care Unit and Intermediate Care Respiratory Unit, Paraplegics National Hospital, Toledo (Spain).Patients We collected data on all patients discharged from the Hospital with permanent respiratory support by volumetric respirator or diaphragmatic pacemaker during a follow-up period of 25 years. Personal interviews were conducted to evaluate health-related quality of life. Comparison and survival tests were used for statistical comparisons. Interventions Quality of life questionnaire. Main variables The main variables collected were demographic data, hospital stay, mortality, family reintegration and health-related quality of life. Results We evaluated the clinical records of 101 patients, 37 in the pacemaker-group and 64 in the volumetric respirator-group. Our results show that ICU admission duration and hospitalization as well as family reintegration, without significant differences, with a tendency to greater survival in pacemaker patients (18.18 versus 9.67 years by the Kaplan-Meier method, p<0.001). However, this difference becomes non-significant (p=0.06) after adjustment of the groups by age. Furthermore, better quality of life was found in these same patients with pacemakers in terms of security, communication, sociability, comfort and mobility in the patients. Conclusions Diaphragmatic pacemaker ventilation is an effective alternative to mechanical ventilation with similar efficacy that improve quality of life in patients with severe respiratory failure due to cervical spinal cord injury (AU)

RESUMO

La vejiga es el órgano urogenital más frecuentemente lesionado en los traumatismos cerrados. La rotura vesical debe sospecharse cuando hay hematuria macroscópica y fractura de pelvis. Es importante diferenciar entre rotura vesical intraperitoneal y extraperitoneal, ya que el tratamiento varía. Presentamos un caso de rotura vesical extraperitoneal en un varón de 61 años (AU)

RESUMO

Un varón de 71 años con el diagnóstico de infarto de miocardio es tratado con rtPA y heparina, objetivándose un hematoma lingual que ocasiona disfagia y dificultad respiratoria. El hematoma lingual es una complicación muy rara del tratamiento fibrinolítico, pero potencialmente letal, ya que puede producir obstrucción de la vía aérea superior. La nasoendoscopia de la orofaringe y glotis ayuda a decidir si es precisa la intubación para asegurar la vía aérea, siendo la intubación nasal con fibrobroncoscopia y anestesia local de elección en esta situación (AU)

RESUMO

Given the importance attributed to the protection of health care workers against viral Hepatitis B (VHB) by the World Health Organization (WHO) and the Center for Disease Control (CDC), in 1993, the Instituto Peruano del Seguro Social (Social Security Peruvian Institute), today known as ESSALUD, ruled the vaccination of personnel in risk working in the 4 national hospitals, using Cuban vaccine Heberbiovac HB (20mg, schedule 0, 1, 2 months). Our purpose was to evaluate the antibody persistence in the vaccinated individuals after six years from immunization, and the possible presence of HB virus infection markers. Sera from 144 health care workers were studied, for a 70.24% coverage, in relation to the initially seroprotected in the 1993 study. For markers detection, commercial immunoenzymatic methods were used. HBsAg and anti-HBc were negative in all the serology samples studied, thus we conclude that no evidence of infection by this virus was found in any of the vaccinated subjects. AntiHBs was positive, being all of them seroconverted, with seroprotection and hyperresponse as of 91.6% and 43.7% respectively. The mean life time of antiHBs (t 1/2) is three years,predicting that the antibodies level will be over 10 IU/l until after 15 years from the end of the schedule. The subjects under 40 had significantly higher levels of seroprotection and hyperresponse, being the females those that stayed in the upper categories of response. Evaluation of the post-reinforcement memory in the seroconverted, not protected cases, is recommended, as well as extend the work with ESSALUD to other hospitals in the country.

RESUMO

Siguiendo las recomendaciones de la Organización Mundial de la Salud (OMS) y el Centro para el control de las Enfermedades (CDC) en la protección de los trabajadores de la salud contra la hepatitis viral tipo B (VHB), en 1993 el Instituto Peruano de Seguro Social (Hoy ESSALUD), 1993 orientó la vacunación del personal de riesgo en los 4 hospitales nacionales, utilizando la vacuna cuabna Heberbiovac HB ( 20 mg, esquema 0.1. 2 meses). Nos propusimos evaluar la persistencia de los anticuerpos en los vacunados después de seis años de la inmunización y la posible existencia de marcadores de infección por el virus B. Se estudiaron los sueros de 144 trabajdores de la salud, para una cobertura de 70,24 por ciento con relación a los 203 seroprotegidos en el estudio inicial. Para la detección de los marcadores en el suero se emplearon métodos inmunoenzimáticos comerciales. El antecedente fue el HBsAg y el anti-HBc fueron negativos en todas las muestras serológicas, por lo que afirmamos que en ninguno de los vacunados hubo evidencia de infección por este virus. Luego de 6 años anti-HBs fue positivo estando todos seroconvertidos, con seroprotección e hiperrespuesta de 91,6 y 43,7 por ciento respectivamente. Si bien el tiempo de vida media del antiHB (t 1/2) es de 3 años, pronosticándose que los niveles de anticuerpos serán superiores a 10 Ul/L hasta después de 15 años de finalizado el esquema. Los menores de 40 años tuvieron niveles de seroprotección e hiperrespuesta significativamente mayores; manteniéndose las mujeres en categorías de respuesta superiores. Se recomienda evaluar la memoria post-refuerzo en los casos seroconvertidos, no seroprotegidos, y extender el trabajo de vacunación con EsSaluda otros hospitales del país.

RESUMO

La hidatidosis es una enfermedad humana producida por el Echinococcus granulosus. Es endémica en el área mediterránea. La ruptura espontánea o durante la intervención quirúrgica de un quiste hidatídico puede acompañarse de fiebre, eritema cutáneo generalizado, urticaria, y en raras ocasiones shock anafiláctico (1 por ciento-7,5 por ciento). Asimismo el infarto agudo de miocardio es una manifestación poco frecuente de anafilaxia. El diagnóstico de quiste hidatídico es difícil cuando se desconoce la existencia de la enfermedad. Presentamos un caso de shock anafiláctico e infarto agudo de miocardio como primera manifestación de hidatidosis hepática. (AU)
