RESUMO
PURPOSE: Grenada is a small island nation of 105,000 in the Caribbean with one single general hospital and pathology laboratory. This study assesses cancer incidence on the island based on existing pathology reports, and compares the cancer mortality burden between Grenada and other Caribbean nations. METHODS: Age-adjusted overall and site-specific cancer "incidence" rates (based on pathology reports) and mortality rates were calculated and compared for 2000-2009. Next, mortality rates for a more recent period, 2007-2013, were calculated for Grenada and a pool of English-speaking, majority African-ancestry Caribbean island nations. Lastly, for direct mortality comparisons by cancer site, mortality rate ratios were computed using negative binomial regression modeling. RESULTS: The pathology reports alone do not suffice to calculate national incidence rates but cancer mortality rates are rapidly increasing in Grenada. The leading causes of cancer mortality were prostate and lung cancers among men, and breast and cervical cancers among women. Overall cancer mortality is significantly higher for both male and female Grenadians than their Caribbean counterparts: RR 1.43 (95% CI 1.32-1.55) and RR 1.26 (95% CI 1.15-1.38), respectively. High prostate and non-Hodgkin's lymphoma rates are concerning. CONCLUSIONS: Given the small existing cancer infrastructure, excessive mortality in Grenada compared to its neighbors may be disproportionately more attributable to low survival than a high cancer risk. Global solutions will be required to meet the cancer control needs of geographically isolated small nations such as Grenada.

INTRODUCTION: Pancreatic trauma results in high morbidity and mortality, in part caused by the delay in diagnosis and subsequent organ dysfunction. Optimal operative management strategies remain unclear. We therefore sought to determine CT accuracy in diagnosing pancreatic injury and the morbidity and mortality associated with varying operative strategies. METHODS: We created a multicenter, pancreatic trauma registry from 18 Level 1 and 2 trauma centers. Adult, blunt or penetrating injured patients from 2005 to 2012 were analyzed. Sensitivity and specificity of CT scan identification of main pancreatic duct injury was calculated against operative findings. Independent predictors for mortality, adult respiratory distress syndrome (ARDS), and pancreatic fistula and/or pseudocyst were identified through multivariate regression analysis. The association between outcomes and operative management was measured. RESULTS: We identified 704 pancreatic injury patients of whom 584 (83%) underwent a pancreas-related procedure. CT grade modestly correlated with OR grade (r 0.39) missing 10 ductal injuries (9 grade III, 1 grade IV) providing 78.7% sensitivity and 61.6% specificity. Independent predictors of mortality were age, Injury Severity Score (ISS), lactate, and number of packed red blood cells transfused. Independent predictors of ARDS were ISS, Glasgow Coma Scale score, and pancreatic fistula (OR 5.2, 2.6-10.1). Among grade III injuries (n = 158, 22.4%), the risk of pancreatic fistula/pseudocyst was reduced when the end of the pancreas was stapled (OR 0.21, 95% CI 0.05-0.9) compared with sewn and was not affected by duct stitch placement. Drainage alone in grades IV (n = 25) and V (n = 24) injuries carried increased risk of pancreatic fistula/pseudocyst (OR 8.3, 95% CI 2.2-32.9). CONCLUSION: CT is insufficiently sensitive to reliably identify pancreatic duct injury. Patients with grade III injuries should have their resection site stapled instead of sewn and a duct stitch is unnecessary. Further study is needed to determine if drainage alone should be employed in grades IV and V injuries. LEVEL OF EVIDENCE: Epidemiologic/Diagnostic study, level III.

BACKGROUND: Two decades ago, hypotensive trauma patients requiring emergent laparotomy had a 40% mortality. In the interim, multiple interventions to decrease hemorrhage-related mortality have been implemented but few have any documented evidence of change in outcomes for patients requiring emergent laparotomy. The purpose of this study was to determine current mortality rates for patients undergoing emergent trauma laparotomy. METHODS: A retrospective cohort of all adult, emergent trauma laparotomies performed in 2012 to 2013 at 12 Level I trauma centers was reviewed. Emergent trauma laparotomy was defined as emergency department (ED) admission to surgical start time in 90 minutes or less. Hypotension was defined as arrival ED systolic blood pressure (SBP) ≤90 mm Hg. Cause and time to death was also determined. Continuous data are presented as median (interquartile range [IQR]). RESULTS: One thousand seven hundred six patients underwent emergent trauma laparotomy. The cohort was predominately young (31 years; IQR, 24-45), male (84%), sustained blunt trauma (67%), and with moderate injuries (Injury Severity Score, 19; IQR, 10-33). The time in ED was 24 minutes (IQR, 14-39) and time from ED admission to surgical start was 42 minutes (IQR, 30-61). The most common procedures were enterectomy (23%), hepatorrhaphy (20%), enterorrhaphy (16%), and splenectomy (16%). Damage control laparotomy was used in 38% of all patients and 62% of hypotensive patients. The Injury Severity Score for the entire cohort was 19 (IQR, 10-33) and 29 (IQR, 18-41) for the hypotensive group. Mortality for the entire cohort was 21% with 60% of deaths due to hemorrhage. Mortality in the hypotensive group was 46%, with 65% of deaths due to hemorrhage. CONCLUSION: Overall mortality rate of a trauma laparotomy is substantial (21%) with hemorrhage accounting for 60% of the deaths. The mortality rate for hypotensive patients (46%) appears unchanged over the last two decades and is even more concerning, with almost half of patients presenting with an SBP of 90 mm Hg or less dying.

BACKGROUND: Cirrhosis may be a risk factor for mortality following blunt splenic injury (BSI) and it predicts the need for an operative intervention. METHODS: We performed a case-control study at 3 level 1 trauma centers. Comparisons were made with chi-square test, Wilcoxon rank-sum test, and binary logistic regression, and stratified by propensity for splenectomy. Data are presented as odds ratios (ORs) and 95% confidence intervals (95% CIs). RESULTS: Mortality was 27% (21/77) and cirrhosis was a strong risk factor for death (OR 8.8, 95% CI 3.7 to 21.1). Compared with controls, cirrhosis was an independent risk factor for splenectomy (OR 5.4, 95% CI 2.5 to 11.5), and only splenic injury grade was associated with splenectomy (OR 2.2, 95% CI 1.3 to 3.6). Only admission model for end-stage liver disease was independently associated with mortality after an operation (OR 1.7, 95% CI 1.1 to 2.8). After propensity score matching, we found no association between splenectomy and mortality in cirrhotic patients. CONCLUSION: Cirrhosis dramatically increases mortality and the odds of an operative intervention in BSI patients with pre-existing cirrhosis, and BSI requires vigilant attention and early intervention should be considered.
