ABSTRACT

Introducción: Los agonistas LHRH son de elección en bloqueo androgénico por cáncer prostático. En base a pacientes castrados se considera un bloqueo adecuado una testosterona total plasmática < 50 ng/dl. Se ha sugerido controlar la testosterona total por la posibilidad de no lograr una supresión adecuada. Material y método: Entre junio de 2008 a marzo de 2009 se midió el nivel de testosterona total al tercer mes de administrada una dosis de leuprolide 11,25 mg IM. Los exámenes se realizaron en la mañana y en el mismo laboratorio. En un grupo de pacientes se estimó peso, talla e índice de masa corporal (IMC) y se evaluó su asociación con los niveles de testosterona alcanzados. Resultados: Se evaluaron 81 pacientes, la edad promedio fue 76,4 años. La testosterona total plasmática promedio fue 33,9 ng/dl. En 12/81 pacientes (14,8 por ciento) el nivel de testosterona fue menos 50 ng/dl. No se observó asociación entre la duración de hormonoterapia y los niveles de testosterona. En 40 pacientes se estimó peso, talla e IMC sin encontrarse asociación de estas variables con el nivel de testosterona. En los pacientes en que se aumentó la dosis a leuprolide 22,5 mg se obtuvo una adecuada supresión de testosterona. Conclusión: En los pacientes en tratamiento con agonistas LHRH se debe medir el nivel de testosterona plasmática dada la posibilidad de un bloqueo inadecuado. En pacientes en tratamiento con leuprolide 11,25 mg y testosterona menos 50 ng/dl el aumento de la dosis a 22,5 mg lograría un nivel de testosterona en rangos de castración quirúrgica.


Introduction: The agonistas are LHRH of election in blockage androgenic for prostatic cancer. On the basis of castrated patients considers an adequate blockage a total plasmatic testosterone < 50 ng/dl. The total testosterone for the possibility to not to achieve an adequate suppression has been suggested to control. Material and method: Between June 2008 to March 2009 leuprolide’s dose measured the level of total testosterone itself to person under administration’s third month 11.25 mg IM. The exams had done in the morning and at the same laboratory. Weight, size and index of muscle mass (IMC) were estimated in patients’ group and his association with the levels of testosterone caught up with was evaluated. Results: We evaluated 81 patients, the mean age was 76.4 years. The total testosterone the average plasmatic was 33.9 ng/dl. In 12/81 patient (14.8 percent) the level of testosterone was > 50 ng/dl. we did not observe association between hormonoterapia’s duration and the levels of testosterone. Weight, size and IMC without finding association of these variables with the level of testosterone were estimated in 40 patients. We got an adequate suppression from testosterone in the patients that 22.5 mg increased itself the dose in to leuprolide. Conclusion: LHRH must try on in the patients in treatment with agonistic the level of plasmatic testosterone once the possibility of an inadequate blockage was given. In patients in treatment with leuprolide 11.25 mg and testosterone > 50 ng/dl the increase of the dose to 22.5 mg would achieve a level of testosterone in ranges of surgical castration.

ABSTRACT

Introducción: El tumor de células pequeñas redondas desmoplásico (TCPRD), es una neoplasia agresiva maligna poco frecuente que afecta a adolescentes y adultos jóvenes. Usualmente son intraabdominales asociados con un mal pronóstico. Existen algunas publicaciones donde incluyen manifestaciones paratesticulares. Caso: Reportamos un caso de un joven de 29 años que consulta por aumento de volumen del hemiescroto izquierdo de 3 meses de evolución. Al examen destacaba 2 nódulos duros uno en relación al polo inferior y el otro al epidídimo de aproximadamente 2 cm. Alfafetoproteína y beta HCG eran normales. Se decide exploración quirúrgica donde biopsia rápida confirma tumor que se origina en las envolturas y que infiltra hacia el testículo. La biopsia definitiva informó tumor desmoplásico de células pequeñas redondas. El estudio de extensión con tomografía axial computarizada y radiografía de tórax no mostró metástasis. El paciente recibió 2 ciclos de QMT con ciclofosfamida, etoposido, adriamicina y cisplatino, con buena tolerancia, evolucionando con depresión medular moderada que se recupera. Actualmente 6 años después del diagnóstico el paciente se encuentra en remisión completa. Discusión: Al parecer y según los últimos reportes de la literatura, la ubicación paratesticular ha mostrado mejor pronóstico en comparación con los tumores abdominales. Se debe incluir este diagnóstico diferencial al enfrentarse con tumores paratesticulares.


Introduction: Small round cell desmoplastic tumor (SRCDT) is an infrequent malignant tumor that affects adolescents and young adults. Usually they occur in the abdomen. Paratesticular manifestations have been reported. Case report: A 29 year old male presented with a 3 month history of a mass in the left scrotum. Physical exam showed 2 hard nodules in the scrotum. Serum levels of alpha-fetoprotein and beta-HCG were normal. The patient was submitted to surgery. Frozen section confirmed a tumor arising in the paratesticular area with involvement of the testis. Permanent sections showed a SRCDT. CT scans and chest x-rays showed no metastases. The patient received two courses of ciclophosphamide, etoposide, adryamicin and cisplatinum. Treatment was well tolerated. The patient is in complete remission at 6 years following the diagnosis. Discussion: Paratesticular location seems to have a better prognosis compared to intraabdominal tumors. SRCDT should be included in the differential diagnosis of paratesticular tumors.

ABSTRACT

Introduction: transurethral resection of the prostate (TURP) is still the gold standard treatment of prostatic obstruction. The objective of the present study is to compare the bleeding complications of TURP with and without the participation of residents. Material and methods: The data was obtained from a prospective protocol that included 200 patients submitted to TURP. Eleven patients were excluded from the study (5,5 percent). No patient was lost from follow-up. Results: Were viewed 189 surgeries, 46 with resident participation (24,3 percent). The operations performed by residents were more prolonged, and required more days with bladder drainage. The following bleeding complications were observed: 1) Bladder catheter washing to solve obstruction by clots: 11,6 percent, 2) Endoscopic revision in severe hematuria: 2,6 percent, 3) Readmission to the hospital in complete urinary retention secondary to clots: 2,1 percent and 4) Blood transfusion: 2,1 percent. The transfusion rate was significantly higher in resident surgeries (6,5 percent versus 0,7 percent, p=0,045), without differences in the other bleeding complications. Conclusion: The rate of bleeding complications is comparable to that recently published. Applying strict criterion for blood transfusion, no difference was observed between the groups. At our institution, the process of teaching and learning TURP does not increase significantly the risk of bleeding complications.
