Objetivos. Identificar factores de riesgo para neonatos a término pequeños para la edad gestacional. Materiales y métodos. Cohorte retrospectiva que utilizó datos del Sistema Informático Materno Perinatal del Hospital María Auxiliadora de Lima, del período 2000 a 2010. Se evaluó la edad materna, paridad, nivel educativo, estado civil, índice de masa corporal pregestacional, número de controles prenatales, presencia de patologías como preeclampsia, eclampsia, infección urinaria y diabetes gestacional como factores de riesgo en pequeños para edad gestacional. El peso para la edad gestacional fue calculado sobre la base de percentiles peruanos. Se calcularon los riesgos relativos crudos (RR) y ajustados (RRa) con sus intervalos de confianza al 95% usando modelos lineales generalizados log binomial.

Background: Pancreatitis caused after transurethral resection of the prostate (TURP) is an uncommon complication, with few reports found in the literature. Here we present the case of a middle-aged patient without comorbidities with this pathology. Clinical case: A 66-year-old male patient with no prior medical history underwent TURP surgery due to benign prostatic hyperplasia. The evolution was unfavourable, leading to post TURP syndrome. On the fifth day after surgery, the patient was admitted for emergency dialysis. During his emergency stay, the patient was unstable; he was diagnosed with pancreatitis, moving to an intensive care unit for management The patient progressed favourably from renal failure and pancreatitis, and on the 5th day the patient was discharged, tolerating oral feeding and stabilized renal failure. Conclusions: Pancreatitis caused by TURP is very rare. This complication has been reported in the literature infrequently and should be suspected when there is pain in the epigastrium. If this complication is suspected, imaging tests and pancreatic enzyme levels should be immediately requested, as it can have an unfavourable evolution until death.

Background: Bladder adenocarcinoma (AC) is a scarce histological variant and there are few studies on its proper management. No previous case reports present the management of a urachal tumor and the incidental finding of bladder adenocarcinoma. Clinical case: We present the case of a young woman with nonspecific symptoms, who presented with a prior history of dysuria, bladder tenesmus, suprapubic pain and urinary urgency for one year, which had been treated as recurrent urinary tract infection. A partial cystectomy plus extended lymphadenectomy was scheduled. We found a bladder tumor with characteristics of a urachal tumor and the pathological report indicated a primary bladder AC. The patient had a complete recovery at one year of follow-up. Conclusions: A patient can present with a tumor with urachal characteristics; however, the pathology report can show primary AC. The decision to perform partial cystectomy was an appropriate option for the location of this tumor, with optimal surgical results. Still, a long-term follow-up is necessary. More specific management guidelines are required for the treatment of AC.
