RESUMO
BACKGROUND: Kidney transplant recipients are vulnerable to infections, especially cytomegalovirus (CMV) disease. It is recommended that clinicians plan their prophylaxis and therapeutic regimens based on viral load testing. OBJECTIVE: CMV viral load monitoring testing provides useful information for identifying virologic response and possible antiviral resistance. Due to the paucity of medical literature on guiding viral therapy in cases of CMV tissue disease with nondetectable serum viral load, we intend to provide physicians with evidence on how to guide medical therapy in these cases. CASE REPORT: A 49-year-old Hispanic male recipient of a kidney transplant from a cadaver donor presented to the emergency department with anorexia, asthenia, diarrhea, weight loss, and supraclavicular and mediastinal adenomegalies at 2 months post-transplantation. Both patients were serum IgG- and IgM-positive for CMV, which classified them as intermediate risk for developing CMV disease or tissue-invasive disease (donor-positive/recipient-positive [D+/R+]). The patient was induced with basiliximab and methylprednisolone and received maintenance therapy with tacrolimus, mycophenolic acid, and prednisone. Real-time polymerase chain reaction analyses were performed due to suspicion for BK virus, B19 parvovirus, Epstein-Barr virus, and CMV, with an undetectable viral load for all. A biopsy specimen taken from the gastrointestinal tract confirmed CMV infection, which was corroborated through immunocytochemistry. CONCLUSIONS: Histopathologic testing is a possible option for patients with CMV tissue disease symptoms but no detectable serum viral load. Clinical observation is fundamental when viral monitoring is difficult.

RESUMEN Los traumatismos en cuello se pueden clasificar las lesiones en contusas y penetrantes, en el caso de las heridas penetrantes las ocasionadas por arma punzocortante son las más frecuentes. Las manifestaciones clínicas dependen del mecanismo del trauma, tamaño y nivel de la lesión. Paciente masculino de 26 años de edad con heridas por arma punzocortante en cuello y muñecas se ingresó a quirófano de urgencia, se realizó una exploración vascular de cuello encontrando una avulsión completa del ligamento cricotiroideo, se realizó la reparación del defecto con un colgajo de los músculos cricotiroideos, cursando una buena evolución es egresado al duodécimo día. El diagnóstico de las lesiones traqueales es desafiante y debe realizase rápidamente. Se debe instalar una vía aérea definitiva de manera eficaz y planear la reconstrucción quirúrgica. El seguimiento postoperatorio realizado de manera interdisciplinaria es esencial para el pronóstico(AU)
ABSTRACT Neck injuries can be classified as blunt or penetrating injuries. Penetrating injuries caused by a puncturing gun are the most frequent. The clinical manifestations depend on trauma mechanism, and on lesion size and degree. We present the case of a 26-year-old male patient with puncture injuries to the neck and wrists. After he was admitted to the emergency room, a vascular exploration of the neck was performed, finding a complete avulsion of the cricothyroid ligament. The defect was repaired with a flap of the cricothyroid muscles. The patient had a good evolution and was discharged on the twelfth day. The diagnosis of tracheal lesions is challenging and must be carried out quickly. A definitive airway should be installed efficiently, as well as the planning of the surgical reconstruction. The postoperative follow-up performed in an interdisciplinary way is essential for the prognosis(AU)

Objetivo: El objetivo del presente trabajo fue analizar la frecuencia y presentación de recidiva de hepatopatías postrasplante no virales. Métodos y Resultados: Los pacientes con hepatopatías no virales que recibieron un trasplante hepático fueron 39 y de éstos, seis presentaron recidiva de la enfermedad (15.3%): uno con recaída del alcoholismo, tres con enfermedad autoinmune (dos trasplantados por cirrosis biliar primaria recurrieron con hepatitis autoinmune y uno con diagnóstico original de cirrosis hepática criptogénica presentó recurrencia de hepatitis autoinmune), uno con diagnóstico de esteatohepatitis no alcohólica tuvo recurrencia con la misma enfermedad; por último, un paciente se trasplantó por cirrosis hepática secundaria a metotrexate y postrasplante manifestó cirrosis biliar secundaria a estenosis del colédoco en el sitio de la anastomosis. Conclusiones: Todos los pacientes aquí analizados presentaron recidiva en el largo plazo (después de 11 meses postrasplante). La recidiva del alcoholismo se identificó en 8.3%, de las hepatopatías autoinmunes en 30%, y de la esteatohepatitis no alcohólica en 20% de los casos. Las tres pacientes con recidiva de hepatopatía autoinmune presentaron en el postras-plante una enfermedad diferente a la que dio origen al trasplante.
OBJECTIVE: We describe the recurrence of non-viral liver disease after orthotopic liver transplantation (OLT). METHODS AND RESULTS: We studied 39 patients who received an OLT for non-viral chronic liver disease. Six (15.3%) of these patients presented disease recurrence after OLT, one following alcohol abuse, 3 presented autoimmune liver disease [2 received an OLT for primary biliary cirrhosis and recurred as autoimmune hepatitis (AIH) one patient had cryptogenic cirrhosis before OLT and recurred as AIH]. One patient showed recurrence of a non-alcoholic steatohepatitis (NASH). One patient received an OLT for cirrhosis secondary to the use of metothrexate and post OLT developed secondary biliary cirrhosis due to a choledocal stenosis in the anastomotic site. CONCLUSIONS: All patients described here displayed long term recurrence (after 11 months post OLT). The recurrence of alcoholism was 8.3% among patients transplanted for this condition. AIH was observed in 30% of cases and NASH in 20%. All three patients with autoimmune liver disease recurred with a different autoimmune disease post OLT.
