ABSTRACT

INTRODUCTION: Non-battle injuries have been the leading cause of medical evacuation in the recent wars in Afghanistan and Iraq. This study investigates the hypothesis, that the occurrence of knee problems could be associated with mounted patrolling in armoured vehicles independent of other risk factors. METHOD: Retrospective questionnaire-based cohort study of Danish soldiers deployed to Afghanistan during 1 February-31 July 2013. RESULTS: 307 soldiers included. Response rate 70%. 33% reported knee pain. MAIN FINDING: Significant association between knee pain and time spent weekly on mounted patrols (OR 1.23, CI 1.07 to 1.41, p=0.003). Controlled for confounders age, body mass index and duration of military employment (OR 1.22, CI 1.06 to 1.41, p=0.006). Adjusted for confounders and all other risk factors (OR 1.25, CI 1.07 to 1.48, p=0.007). The main finding in a subset of the 33% with knee pain: Significant association between more severe knee problems with Knee injury and Osteoarthritis Outcome Score below 400 and time spent weekly on mounted patrols (OR 1.49, CI 1.17 to 1.56, p=0.002). CONCLUSIONS: A major concern regarding knee problems among Danish deployed military personnel is identified. The risk of suffering from knee problems and the severity of symptoms increase with the amount of time spent inside a vehicle on mounted patrols.

ABSTRACT

OBJECTIVE: to evaluate ultrasound guided compression (UGC) for the treatment of iatrogenic femoral pseudoaneurysms (PA). DESIGN: retrospective follow-up of 130 patients with suspected PA referred from the cardiac catheterisation laboratory over a 36-month period. RESULTS: the overall incidence of PA was 0.5% and was significantly higher after therapeutic (1.5%) than diagnostic (0.3%) procedures (p <0.000001). Forty-eight patients with a PA were treated with UGC with an 88% success rate. Success did not appear to be related to PA diameter. CONCLUSION: the efficacy of UGC as treatment of PAs is confirmed.

ABSTRACT

OBJECTIVES: to assess the diagnostic value of colonoscopy in ischaemic colitis following abdominal aortic surgery, based on a literature review, and to introduce the concept of evidence-based medicine. METHOD: a review of the literature according to evidence-based principles was made by all doctors of our department. RESULTS: seven prospective non-randomised reports on routine colonoscopy after abdominal aortic surgery were found. None of the participants found all the reports, and the last was identified by the reviewer. CONCLUSIONS: Endoscopy may disclose ischaemic colitis, but cannot separate transmural from the clinically less important mucosal ischaemia. Endoscopy had no impact on mortality in any of the prospective series. The evidence-based conference was an inspiring teaching modality, and illustrated for the participants the difficulty in performing a targeted literature search.

ABSTRACT

The importance of physiological plasma levels of secretin in biliary bicarbonate secretion is not known. However, in anaesthetized pigs the substantial hepatic output of bicarbonate into the duodenum in response to low doses of secretin exceeds pancreatic bicarbonate output. The aim was therefore to study the relationship between duodenal acidification, secretin and hepatic biliary bicarbonate output in the conscious pig. Göttingen minipigs (n = 22) were cholecystectomized and the common bile duct catheterized. The biliary bicarbonate secretion in response to intraduodenal HCl, secretin or pentagastrin given intravenously, and to meal was studied. Intraduodenal HCl infusion, secretin and pentagastrin given intravenously augmented hepatic bicarbonate output and plasma secretin concentrations significantly. The secretin response to acidification was sufficient to explain the subsequent increase in biliary bicarbonate secretion. Hepatic bicarbonate secretion and concentrations of CCK and secretin in plasma increased postprandially. Exclusion of bile salts from the duodenum abolished postprandial increase in bile volume and increased release of CCK in fasting and fed pigs whereas secretin release was diminished. The results demonstrate that hepatic bicarbonate secretion is stimulated by endogenous secretin and therefore may have a physiological role in duodenal neutralization.

ABSTRACT

BACKGROUND: The mechanism behind the possible feedback regulation of pancreatic exocrine secretion is not well understood. METHODS: Thirteen minipigs were prepared with fistulas to the pancreatic duct and the duodenum. Peripheral venous blood was obtained for determination of secretin and cholecystokinin (CCK) levels. Four different experiments were performed: 1) diversion and reinfusion of pancreatic juice; 2) intraduodenal infusion of NaHCO3 solution, with the same volume, bicarbonate concentration, and osmolality as the collected pancreatic secretion, and reinfusion of pancreatic juice; 3) reinfusion of pancreatic secretion for 1 h before and 2 h after a meal; and 4) diversion of pancreatic secretion and intraduodenal infusion of NaHCO33 solutions before and after a meal. RESULTS: Reinfusing pancreatic juice significantly decreased pancreatic juice volume and bicarbonate output and slightly decreased the level of secretin in plasma. Alternating infusions of substitute NaHCO3 and pancreatic juice did not change pancreatic output of bicarbonate and protein, nor did it change the CCK and secretin levels in plasma. Replacing pancreatic juice with intraduodenal NaHCO3 infusions during a meal did not significantly modify the pancreatic secretion of bicarbonate and protein or the hormonal levels in blood. CONCLUSIONS: A negative feedback regulation of pancreatic exocrine secretion is present in starved minipigs. Duodenal acidity and plasma levels of secretin semm to be of importance, whereas duodenal enzyme activity and the level of CCK in plasma probably are not. A postprandial negative feedback regulation through duodenal enzymatic activity and release of CCK into blood could not be shown.
