RESUMO
OBJECTIVE: to measure the compliance, security and usefulness of organic mesh (bovine pericardium) in the repair of abdominal defect in an animal model. METHODS: Wistar rats (weight 300 to 500 g), were anesthetized and an abdominal defect of 1 cm in each animal was performed. Animals were divided according to the repair material used: bovine pericardium mesh (n = 6) and polipropilene mesh (n = 6). Animals were sacrificed on day 28 after the surgery. Presence of infection, necrosis and adherences (macroscopic and microscopic) were compared. Tensile force was also measured in both groups. RESULTS: inflammation, necrosis and adherences were similar in both groups. The prolene mesh (mean rupture force 66.5 joules) was stronger than bovine pericardium (mean rupture force 47.4 joules) p = 0.002, however, had also more adherences. CONCLUSIONS: there is no difference between inflammation, necrosis and adherences. But the polipropilene mesh was stronger than the bovine pericardium mesh. This finding could have relevance in the clinical practice (hernia recurrence).

Objetivo: Demostrar si existe diferencia en los resultados del manejo de pacientes con quemaduras por electricidad de alto y bajo voltaje en el Antiguo Hospital Civil de Guadalajara y comparar nuestros resultados con lo publicado en la literatura. Sede: Antiguo Hospital Civil ''Fray Antonio Alcalde'' (tercer nivel de atención). Diseño: Estudio descriptivo y retrospectivo. Análisis estadístico: Para el análisis de variables no paramétricas se utilizó la prueba de χ² y para variables paramétricas la prueba t de Student, considerando estadísticamente significativo un valor de p ≤ a 0.05. Pacientes y métodos: Pacientes con quemaduras por electricidad en el periodo del 1 de enero del 2010 al 31 de diciembre del 2010. Se incluyeron todos los pacientes con quemaduras por electricidad y se dividieron en dos grupos: grupo I, pacientes con quemaduras por alto voltaje y grupo II, pacientes con quemaduras de bajo voltaje. Las variables estudiadas fueron edad, sexo, ocupación, estado civil, tipo de quemadura (alto o bajo voltaje), sitio de entrada, sitio de salida, tiempo entre la lesión y la llegada a urgencias, porcentaje de superficie corporal quemada, tratamiento establecido, volumen urinario, mioglobinuria, procedimientos quirúrgicos, días de estancia hospitalaria y mortalidad. Resultados: Se incluyeron un total de 22 pacientes adultos, 19 hombres y 3 mujeres. El grupo I incluyó 8 pacientes y el grupo II 14 pacientes. Todos los pacientes llegaron al servicio de urgencias dentro de las primeras 24 horas posteriores al accidente. Los pacientes con quemaduras por alto voltaje presentaron mayor estancia hospitalaria (p 0.0035). Se presentó únicamente una muerte, perteneciente al grupo I. Conclusión: Las quemaduras por alto voltaje confieren mayor morbimortalidad y mayor estancia hospitalaria.
Objective: To demonstrate whether there is a difference in the results of handling patients with high or low voltage-induced burns treated at the Antiguo Hospital Civil de Guadalajara and to compare our results with those in the literature. Setting: Antiguo Hospital Civil ''Fray Antonio Alcalde'' (third level health care hospital). Design: Descriptive, retrospective study. Statistical analysis: χ2 square test was used for non-parametric variables and Student's t test was used for parametric variables. Statistical significance was set at p ≤ than 0.05. Patients and methods: Patients with electrical burns cared for from January 1, 2010 to December 31, 2010. All patients with electrical burns were included and were divided in two groups: group I, those with high voltage burns, and group II those with low voltage burns. Variables studied were: age, sex, occupation, civil status, type of burn (high or low voltage), entrance site, exit site, time elapsed between injury and arrival to the emergency care, percentage of burnt body surface, established treatment, urinary volume, myoglobinuria, surgical procedures, days of in-hospital stay, and mortality. Results: A total of 22 adult patients were included, 19 men and 3 women. Group I consisted of 8 patients and group II of 14 patients. All patients arrived at the emergency ward within the first 24 hours after the accident. Patients with high-voltage burns had longer in-hospital stays (p 0.0035). There was only one death, pertaining to group I. Conclusion: High voltage burns lead to greater morbidity and mortality, and to a longer in-hospital stay.
