RESUMO
BACKGROUND: There are few large prospective cohort studies evaluating predictors of outcomes in acute pancreatitis. OBJECTIVES: The purpose of this study was to determine the role of age and co-morbid disease in predicting major outcomes in acute pancreatitis. METHODS: Data points were collected according to a predefined electronic data collection form. Acute pancreatitis and its complications were defined according to the revised Atlanta classification. Univariable and multivariable analyses were conducted using Cox proportional hazard regression and multiple logistic regression. RESULTS: From June 2013-February 2015, 1655 adult patients were recruited from 23 centres across Spain. Co-morbid disease, obesity, open surgical necrosectomy within 30 days, and pancreatic necrosis were independently associated with both 30-day mortality and persistent organ failure (p < 0.05 for all). Age was not associated with persistent organ failure, however the extreme of age (>85 years) was associated with mortality (p < 0.05). Co-morbid disease and obesity were not independently associated with a prolonged length of stay or other markers of morbidity on adjusted analysis (p > 0.05). CONCLUSION: Comorbidity and obesity are important determinates of mortality and persistent organ failure in acute pancreatitis, but in the absence of organ failure they do not appear to independently contribute to morbidity. This has important implications for severity classification and predictive models of severity in acute pancreatitis.
RESUMO
Presentamos el caso de un niño de 9 años de edad, en quien como hallazgo incidental en una radiografía de tórax se observa una calcificación en el hipocondrio izquierdo sugestiva de masa. Se amplía el estudio mediante ecografía y resonancia magnética (RM) abdominal para mejor caracterización: se visualiza una masa suprarrenal izquierda, predominantemente quística, con un nódulo sólido. Finalmente, se le practica una resección quirúrgica, en la cual se llega al diagnóstico de ganglioneuroblastoma nodular quístico, tras el análisis histopatológico. El ganglioneuroblastoma quístico es un tumor poco frecuente, originado en las células ganglionares del sistema nervioso simpático. El sitio de origen más frecuente son las glándulas suprarrenales. A pesar de que el diagnóstico definitivo se suele realizar tras la resección quirúrgica del tumor, con la ecografía y la RM se debe incluir entre los diagnósticos diferenciales de incidentalomas suprarrenales en un niño o un paciente joven. Los hallazgos en tomografía computarizada son variables.
We present the case of a child patient aged 9 years, in whom, as an incidental finding in chest X-rays, a calcified lesion was observed in the left hypochondrium. The study is extended by ultrasound and then MRI was performed to better characterize it. These showed a left adrenal, predominantly cystic mass with a solid nodule. The surgical team decided to perform resection of the mass and submit it for histopathological examination. A definitive diagnosis of cystic nodular ganglioneuroblastoma was made. Ganglioneuroblastoma is a rare tumour, originating in ganglion cells of the sympathetic nervous system. The site of more frequent origin is in the adrenal glands. Although the majority are diagnosed based on the postoperative histological analysis, with ultrasound and MRI we should include it among the differentials diagnoses of adrenal incidentalomas in a child or young patient. The findings on CT are variables.

OBJECTIVE: To determine if hepatic lipomas have a higher prevalence of liver steatosis than other benign hepatic lesions. MATERIALS AND METHODS: Ninety-two benign hepatic lesions were analyzed with magnetic resonance (MR) imaging. There were 6 lipomas and 86 benign non-lipomatous lesions, including 55 hemangiomas, 23 focal nodular hyperplasias (FNH) and 8 adenomas. All studies included a chemical shift T1-weighted sequence (in-phase and opposed-phase) in order to evaluate the presence of steatosis. RESULTS: A statistically significant relationship (Fischer's Exact Test, p=0.019) between hepatic lipomas and steatosis was demonstrated. Fifty percent of hepatic lipomas associated steatosis, while this association was present in only 9% of the non-lipomatous lesions. CONCLUSION: Lipomas have a significantly greater association with steatosis when compared to nonlipomatous lesions. This relationship may be related to a common insuline resistance mechanism.
