Introducción: La resección hepática sigue siendo el método más efectivo de tratamiento de tumores hepáticos. Actualmente, el abordaje laparoscópico se considera como el estándar de oro frente al abordaje abierto; sin embargo, el surgimiento de la cirugía robótica brinda una nueva opción de abordaje mínimamente invasiva con aparentes mejores resultados. El objetivo de esta revisión sistemática es valorar los beneficios de la hepatectomía robótica frente a la hepatectomía laparoscópica en la resección de tumores hepáticos. Metodología: En esta revisión sistemática se incluirán estudios comparativos, de cohorte, de casos y controles, con recolección de datos prospectivos o retrospectivos. Los participantes de los estudios serán pacientes diagnosticados con tumores hepáticos benignos o malignos, incluidos niños y adolescentes, no cirróticos o cirróticos compensados sometidos a intervenciones de hepatectomía robótica y hepatectomía laparoscópica. Las medidas de resultado primarias son: 1. Pérdida de sangre estimada durante el acto quirúrgico, 2. Tiempo operatorio, 3. Tasa de conversión a laparotomía, 4. Tasa de mortalidad intraoperatoria, 5. Tasa de morbilidad (complicaciones postquirúrgicas), 6. Estancia hospitalaria postquirúrgica. Las búsquedas electrónicas se realizarán en PUBMED, MEDLINE, SCIENCEDIRECT (2010 hasta el presente). Se usará la evaluación del riesgo de sesgo de estudios de Cochrane. Como medidas de efecto del tratamiento se utilizarán las diferencias de medias (DM) y los intervalos de confianza (IC) del 95. La evaluación de heterogeneidad se realizará mediante la inspección visual del diagrama de embudo. La evaluación de la calidad de la evidencia y tablas de 'Resumen de hallazgos' se usará el test GRADE.

BACKGROUND: Drug poisoning is an important cause of morbidity and mortality in pediatric patients. However, amlodipine poisoning, a widely used dihydropyridine calcium chanel blocker, is not fully documented in Ecuador. Treatment consists of classic measures for shock management and specific measures for this type of intoxication. CASE REPORTS: We present two case reports, both of teenage patients admitted into the pediatric intensive care unit for suicide attempt by taking amlodipine and some other drugs. EVOLUTION: During hospital stay, they presented a different evolutionary course. In both cases vasoactive drugs were needed, dosage was modified according to clinical course. Also in both patients, calcium gluconate was administered along with other support measures described in this paper. Finally, both patients presented a good outcome and were discharged after psychological and psychiatric assessment and follow up. CONCLUSION: The low frequency of amlodipine poisoning and the lack of evidence-based knowledge, constitute it as a diagnostic and therapeutic challenge. Based on our experience, we highlight the importance of early suspicion and prioritizing the use of vasopressors over fluid resuscitation. Additionally, we recommend documenting the exact dose of intake and inquiring about consumption of other drugs to properly classify the severity of the poisoning and stablish the treatment plan. Finally, constant clinical monitoring and support of laboratory tests will guide the conduct.

Suicide is a major global public health problem, especially among young and middle-aged adults. According to the WHO, worldwide, approximately 800 000 people commit suicide every year. Some predisposing factors for suicide are related to the personal sphere and are universal, such as biological conditions or psychiatric pathology, childhood adversities, as well as social and community perspective: housing situation, religion, social integration and support, unemployment, stress. The highest frequencies of occurrence have been found in males and in the age groups between 15 and 25 years, or over 65 years. Regarding suicide methods, there is a predilection for hanging in most countries, and although suicide methods do not differ much from one country to another, it should be considered that they vary according to the access to lethal methods. Men are reported to commit suicide more frequently using violent methods. A greater recognition of the risk factors and suicide methods used is necessary to raise awarenes among the population and prevention.
