RESUMO

Objetivo: Describir una rara y grave presentación clínica de una patología de difícil diagnóstico inicial. Materiales y métodos: Se presenta el caso de una mujer de 45 años, que ingresa al servicio por múltiples episodios de melena y hematemesis, que cursa con shock hipovolémico y cuyo diagnóstico se constata en una laparotomía exploradora de urgencia. Resultados: Se realiza pancreatectomía corporocaudal; biopsia sin hallazgos malignos; tumor quístico mucinoso de tipo cistoadenoma mucinoso de páncreas y linfonodos sin tumor maligno. Discusión: El cistoadenoma mucinoso del páncreas constituye el 10% de los quistes pancreáticos; la gran mayoría son asintomáticos o cursan con dolor abdominal. El diagnóstico se realiza fundamentalmente por técnicas de imagen, la tomografía axial computarizada o el ultrasonido diagnóstico. La hemorragia digestiva alta es una rara presentación clínica, de baja sospecha diagnóstica que puede iniciar con importante compromiso hemodinámico. La causa del sangrado se atribuye a que este tumor se comunicaba por el ducto pancreático hacia el duodeno. Conclusión: El tratamiento de elección es la resección quirúrgica. La técnica quirúrgica a emplear está determinada por la localización del tumor y su naturaleza.


Purpose: Describe a rare and severe clinical presentation of a disease difficult initial diagnosis. Materials and methods: For a woman of 45, who entered the service for multiple episodes of melena and hematemesis, hypovolemic shock that causes, whose diagnosis is found in an emergency exploratory laparotomy is presented. Results: Subtotal pancreatectomy body and tail is made. Without biopsy findings malignant mucinous cystic tumor mucinous cystadenoma type of pancreas, lymph nodes malign tumor. Discussion: Mucinous cystadenoma pancreas constitutes 10% of pancreatic cysts, the vast majority are asymptomatic or present with abdominal pain. The diagnosis is made primarily by imaging techniques, computed tomography or ultrasound diagnosis. Upper gastrointestinal bleeding is a rare clinical presentation, diagnosis low suspect may debut with important hemodynamic compromise. The cause of bleeding is attributed to this tumor communicated by the pancreatic duct into the duodenum. Conclusion: The treatment of choice is surgical resection. The surgical technique used is determined by the location of the tumor and its nature.

RESUMO

Introducción: La ruptura traqueal es una condición poco frecuente, donde la causa iatrogénica es extremadamente rara, siendo la intubación orotraqueal la causa iatrogénica más frecuente, pudiendo ocurrir en ausencia de intubaciones complicadas, uso de guías o cuff sobreinflado. Su aparición es potencialmente letal, pudiendo manifestarse desde enfisema subcutáneo asintomático en el postoperatorio inmediato hasta la insuficiencia respiratoria aguda, neumomediastino, neumopericardio, neumotórax y muerte. Caso Clínico: Se presenta caso de paciente de sexo femenino de 52 años, obesa, quien presentó una perforación traqueal posterior de 3mm tras intubación difícil no prevista, manifestada en el post operatorio inmediato por enfisema subcutáneo y neumomediastino y evidenciada en scanner de tórax. Es manejada con tratamiento conservador, drenaje de enfisema y antibiótico de amplio espectro. Evolucionando con lesión cicatricial y leve estenosis traqueal según scanner de control. Discusión: La perforación traqueal como complicación de la intubación es una condición rara, donde la obesidad es un factor de riesgo reversible y la aparición de enfisema subcutáneo se convierte en un factor protector al ser un signo precoz que permite sospecharla. No existe concenso en su manejo, por lo que el tratamiento puede ser quirúrgico, conservador o instalación de prótesis de Dumon. El manejo conservador con antibióticos de amplio espectro que abarquen flora traqueobronquial, drenaje del enfisema e intubación distal a la perforación se prefiere en lesiones <2cm, en el 1/3 superior de la tráquea, con síntomas mínimos no progresivos, sin pérdida de aire y respiración espontánea, daño esofágico, signos de mediastinitis ni infección.


Introduction: Tracheal rupture is a rare condition where iatrogenic cause is extremely rare, where tracheal intubation is the most common iatrogenic cause, and can occur in the absence of complicated intubations, use of guides or overinflated cuff. Its appearance is potentially lethal and can manifest from asymptomatic subcutaneous emphysema in the immediate postoperative period to acute respiratory failure, pneumomediastinum, Pneumopericardium, pneumothorax and death. Case report: Is presented a case of a 52 years old female patient, obese, who presented a 3mm posterior tracheal perforation after unanticipated difficult intubation, manifested in the immediate postoperative period by subcutaneous emphysema and pneumomediastinum evidenced in chest scanner. It is managed with conservative treatment, drainage of emphysema and broad-spectrum antibiotic. Evolving with scarring lesion and mild tracheal stenosis according to scanner control. Discussion: Tracheal perforation as a complication of intubation is a rare condition, where obesity is a reversible risk factor and the onset of subcutaneous enpghysema becomes a protector factor as it is an early sign that allows for suspicion. There isn't any consensus in handling, so that treatment may be surgical, conservative or installation of Dumon prosthesis. Conservative management with broad-spectrum antibiotics that cover tracheobronchial flora, emphysema drainage and distal intubation from the perforation is preferred in lesions <2cm, in the upper 1/3 of the trachea, with nonprogressive minimal symptoms, no air loss and spontaneous breathing, esophageal damage, signs of infection or mediastinitis.

RESUMO

Background: Schwannomas are the most common neurogenic tumors of the posterior mediastinum. They are usually asymptomatic and the symptoms associated with them are chest pain, cough and dyspnea. Case report: We report a 36 years old female consulting in the emergency room due to sudden onset dyspnea. The imaging study confirmed the presence of a hemothorax secondary to a tumor of the posterior mediastinum, which was surgically excised. The pathological study reported a Schwannoma.


Introducción: El mediastino es un área anatómica que contiene estructuras y células pluripotenciales que pueden originar distintos tumores. Los Schwannomas son los tumores neurogénicos más comunes del mediastino posterior, se caracterizan por tener un crecimiento lento. A menudo son asintomáticos y se diagnostican como hallazgos radiológicos. Cuando son sintomáticos, lo más común es que presenten dolor torácico, tos y disnea. El hemotórax es una rara forma de manifestación. Caso clínico: Se presenta en este trabajo el caso de una mujer de 36 años, que ingresa al servicio de urgencia por un cuadro de disnea súbita. El estudio por imágenes confirma el diagnóstico de hemotórax, secundario a un tumor de mediastino posterior, el cual requiere cirugía. Anatomía patológica corrobora el diagnóstico presuntivo de Swchannoma de mediastino posterior. Conclusión: La cirugía es necesaria para poder resecar completamente el tumor y en el Schwannoma benigno es curativa.

RESUMO

Background: Ultraviolet light exposure has a pathogenic effect on the development of skin cancer, whose prevalence increases worldwide. In Chile and the rest of the world, preventive educational campaigns are carried out to change high risk sun exposure behaviors. Aim: To study the behavior of the Chilean population towards skin cancer prevention and to identify erroneous preventive practices and concepts. Material and methods: A survey containing 17 questions about sun exposure behaviors, photoprotective measures and knowledge about ultraviolet radiation and skin cancer was used. It was applied during January and February 2004, to 1,143 subjects (mean age 30 years, 409 males), taking vacations in beach resorts in Chile. Results: The hours of higher sun exposure ranged from 12 AM to 4 PM. Thirty seven percent of subjects were exposed more than 2 hours during this high risk lapse. Women and subjects aged less than 25 years were those with the riskiest behaviors. Fifty four percent used some type of photoprotection and 50% used ocular protection. Seventy percent used creams with sun screen and 74% used a sun protection factor higher than 15. Seventy percent applied the sun screen as recommended. Thirty eight percent had at least one sun burn in the last two years. More than 90% of subjects were aware of the relationship between sun exposure and skin cancer but 60% did not know the hours of higher ultraviolet radiation. The information about sun exposure was obtained from television in 57% of surveyed individuals. Conclusions: More educational campaigns about the risk of sun exposure are needed to reduce risky behaviors in the Chilean population.
