[Organ and tissue donation and transplantation: three health care centers' attitude]. / Actitud hacia la donación y el trasplante de órganos y tejidos de tres instituciones de salud.

OBJECTIVE: To assess the knowledge and attitude towards organ donation within health professionals in different institutions of Nuevo Leon. METHODS: A prospective, open, observational, descriptive study of parallel groups, through application of a survey formulated by the Hospital Universitario (HU) "Dr. José Eleuterio González". We applied 208 surveys in the HU (n = 100) and other institutions like IMSS, ISSTE (n = 108). RESULTS: From all the participants, 86% had a positive attitude towards organ donation, associated to a higher education, and information regarding organ donation received by other health professionals. Though having a positive attitude toward organ donation, 14% of health professionals don't support it due to being afraid of not receiving medical assistance, knowing their status of donators, religious reasons, and fear of organ trafficking. CONCLUSIONS: Our study shows that, even within the health professionals, there is a need for information regarding organ donation. A well-instructed health professional shows a higher interest in organ donation; this could have a positive impact in the attitude of the population toward organ donation, as well as in the obtainment of organs inside the medical institutions.

Gastrointestinal Cytomegalovirus Infection in a Transplantation Recipient With a Negative Serum Viral Load: Case Report.

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.

Symptom attribution and stress level in patients with medically unexplained symptoms in a Mexican emergency department.

Background: Patients who come to the emergency department are different from those seen in outpatient clinics. The former suffer greater stress. Aim: Establish an association between the attribution of the symptoms (psychosocial or organic) by the patient and the level of perceived stress in patients with Medically Unexplained Physical Symptoms (MUS) in an emergency department. Methods: A correlational cross-sectional study was conducted in 138 patients with MUS in the emergency department of a 3rd level public hospital where the psychosocial or organic attribution of nonspecific symptom(s) by patients and the perceived stress were measured with validated scales. Bivariate analysis was performed with Chi square for categorical variables, and a Spearman correlation, p <0.05. Results: 75% of patients with psychosocial attribution have higher stress compared to patients with organic symptom attribution (25%). In Spearman's correlation, a medium but statistically significant correlation was obtained. Conclusions: The psychosocial attribution of the patient's complaint might coexist in MUS patients with higher level of perceived stress by the patients. Health professionals might need to address both psychosocial attributions and stress in MUS patients.

Mumps outbreak with high complication rates among residents in a university teaching hospital.

According to the US Advisory Committee on Immunization Practices recommendations, only health care personnel (HCP) with adequate evidence of immunity should be exposed to patients with a suspected diagnosis of mumps. Here we report a hospital-outbreak scenario among medical residents with no previous vaccination record against mumps who had a high rate of complications. We also describe the importance and impact of full and proper vaccination, as well as isolation, of HCP in stopping the outbreak and, finally, review opportunities for improving the safety of HCP.

[Posttransplant relapse in non viral hepatopathies]. / Recidiva postrasplante de hepatopatías no virales.

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.

[Impact of telmisartan on glomerular filtration in laparoscopic surgery. A double blinded randomised controlled study]. / Impacto de telmisartán en la filtración glomerular en cirugía laparoscópica. Estudio aleatorizado doble ciego.

BACKGROUND: Laparoscopic surgery has begun to replace a great number of procedures that were previously practiced using open or conventional techniques. This is due to the minimal invasion, small incisions, and short time recovery. However, it has come to knowledge, that the increase in intra-abdominal pressure due to carbon dioxide pneumoperitoneum during laparoscopic surgery causes cardiovascular, respiratory, endocrine, and renal alterations. OBJECTIVE: To evaluate the nephroprotective effect of telmisartan, an angiotensin II AT1 receptor antagonist, on glomerular filtration in laparoscopic surgery. MATERIAL AND METHODS: Analytical prospective, randomised, double-blind study was conducted on patients undergoing elective laparoscopic cholecystectomy. They were randomised into 2 groups, with the treatment group receiving a single dose of 40mg telmisartan orally 2hours prior to surgery, and the placebo group. RESULTS: There were 20 patients in each group (n=40), with a mean age of 32.65 years in the treatment group. Plasma creatinine did not show any significant change in the different time lapse in which blood samples were taken, but creatinine clearance at the end of surgery (196.415±56.507 vs. 150.1995±75.081; p=0.034), and at 2 h postoperative period (162.105±44.756 vs. 113.235±31.228; p≤0.001) was statistically significant, which supports an increase in renal function in the telmisartan group. CONCLUSION: The use of telmisartan, an angiotensin II AT1 receptor antagonist, offers renal protection during laparoscopic surgery.

Lesión traqueal con reparación de colgajo muscular / Tracheal Injury with Muscle Flap Repair

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)

Recidiva postrasplante de hepatopatías no virales / Posttransplant relapse in non viral hepatopathies

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.
