Pain is a sign of illness and a common complain that bring patients to a health care facility. It is classified in acute or chronic pain, nociceptive or neuropathic, and according to conduction velocity, fast or slowly. C and Aδ- fibers respond to stimuli and produce the experience of pain, this defines them as nociceptors. Central pathways of pain include: nociceptors respond to stimuli and produce the experience of pain when they are electrically stimulated (Transduction); axons of nociceptors enter the spinal cord via the dorsal root, where Glutamate are Substance P are released, spinal neurons send their axons to the contralateral thalamus (Transmission); the perceived intensity of pain can be modulated by brain circuits (Modulation). Pain inhibition is achieved by calcium channel blockage and open potassium channel by endogenous and exogenous opioids, due hyperpolarization of the c...

Objetivo: Determinar las características clínicas y epidemiológicas de los pacientes con intoxicación inducida e intencional, atendidos en un hospital general. Material y métodos: Se incluyeron pacientes con intoxicación inducida e intencional; de ambos sexos, mayores de 14 años. La información se obtuvo de la historia clínica de ingreso, entrevista personal, test de Hamilton y evaluación toxicológica en orina en los intoxicados inducidos. Resultados: De marzo a diciembre del 2006 hubo 45 pacientes con intoxicación inducida y 382 pacientes con intoxicación intencional, de estos últimos se tuvo información completa en 104. Los pacientes con intoxicación inducida en comparación a los intoxicados intencionales fueron varones (p=0,001); de mayor edad (31,62 ± 9,38 vs 26,85 ± 12,18 años) (p=0,011), mayor nivel de instrucción (p=0,04), empleados (p=0,01) y mayor nivel soci...

Introduction: Shoshin Beriberi is a disease generated by thiamine deficiency and is characterized by acute fulminant cardiac dysfunction (1). Objective: To highlight cardiogenic shock and hyperlactacidemia in a patient with shoshin beriberi in an intensive care unit of a general hospital. Material and method: The information was taken from the electronic medical history of the intensive care unit (ICU) of the Cayetano Heredia National Hospital (HNCH) and from laboratory and image records. Case: 22-year-old female patient, with a history of anorexia nervosa, multisystem tuberculosis (TBC); with abdominal pain, vomiting, oral intolerance, prolonged fasting, received total parenteral nutrition (TPN) without thiamine intake and with hospitalization for 40 days on the general floor; Admission to the ICU in cardiogenic shock and hyperlactacidemia with serum lactate 13.8 mmol/L. With sepsis rul...

El tromboembolismo pulmonar (TEP) masivo, es un evento vascular agudo caracterizado por choque obstructivo, con mortalidad alta. El objetivo del reporte fue resaltar la terapia de trombólisis con guía ecocardiográfica en un paciente con tromboembolismo pulmonar (TEP) masivo y arresto cardiopulmonar. Se presenta el caso de un varón de 48 años de edad, con fractura expuesta de tibia izquierda no operada, hospitalizado sin uso de heparina profiláctica, quién cursó con disnea súbita, dolor torácico y arresto cardiopulmonar dos veces, el primero en hospitalización general, y el segundo al ingreso a la unidad de cuidados intensivos (UCI). Post retorno de la circulación espontanea cursó con hipotensión, taquicardia, hipoxemia, Glasgow 4 puntos; en el electrocardiograma se encontró taquicardia sinusal, patrón S1Q3T3, bloqueo completo de rama derecha; en la ecocardiografía relaci...
