e n t r e v i e w i s t o s u m m a r i z e the current knowledge regarding pharmacological prevention and treatment of acute pancreatitis (AP) based on experimental animal models and clinical trials.Somatostatin (SS) and octreotide inhibit the exocrine production of pancreatic enzymes and may be useful as prophylaxis against Post Endoscopic retrograde cholangiopancreatography Pancreatitis (PEP).The protease inhibitor Gabexate mesilate (GM) is used routinely as treatment to AP in some countries, but randomized clinical trials and a meta-analysis do not support this practice.Nitroglycerin (NGL) is a nitrogen oxide (NO) donor, which relaxes the sphincter of Oddi.Studies show conflicting results when applied prior to ERCP and a large multicenter randomized study is warranted.Steroids administered as prophylaxis against PEP has been validated without effect in several randomized trials.The non-steroidal anti-inflammatory drugs (NSAID) indomethacin and diclofenac have in randomized studies showed potential as prophylaxis against PEP.Interleukin 10 (IL-10) is a cytokine with anti-inflammatory properties but two trials testing IL-10 as prophylaxis to PEP have returned conflicting results.Antibodies against tumor necrosis factor-alpha (TNF-α) have a potential as rescue therapy but no clinical trials are currently being conducted.The antibiotics betalactams and quinolones reduce mortality when necrosis is present in pancreas and may also reduce incidence of infected necrosis.Evidence based pharmacological treatment of AP is limited and studies on the effect of potent anti-inflammatory drugs are warranted.
Acute pancreatitis after ERCP is a severe side effect.To evaluate the preventive effect of nitroglycerin on post-ERCP pancreatitis by a meta-analysis of randomized clinical studies.We searched on Pubmed, Embase, Cochrane Library and all abstracts presented at Digestive Disease Week and United European Gastrointestinal Week from 2004 to 2008. We used the MeSH terms 'pancreatitis' together (AND) with the terms: 'glyceryl trinitrate', 'glyceryl dinitrate', 'isosorbide dinitrate' or 'nitroglycerin'.Five clinical studies evaluating the incidence of post-ERCP pancreatitis after administration of nitroglycerin were identified. Meta-analysis including all five studies showed a relative risk (RR) of 0.61 (95% CI; 0.44, 0.86) with the number needed to treat (NNT) of 26 (95% CI: 16, 82). Three studies evaluated nitroglycerin administered by a dermal patch reaching together an RR of 0.66 (95% CI; 0.43, 1.01). The use of nitroglycerin is associated with a significantly increased risk of hypotension (RR 2.25) and headache (RR 3.64). No difference in mortality was observed.Overall, our meta-analysis supports the use of nitroglycerin in the prevention of post-ERCP pancreatitis, but administration of nitroglycerin by the dermal route, which is the preferred route of administration, did not reach statistical significance.

Background In pregnancy, the major causes of morbidity and mortality include diseases that affect circulation profoundly and restoration of normal circulation is a key objective. Focused cardiac ultrasound provides information on the individual determinants of circulation and has a significant impact on patient management. This study aimed to determine the feasibility of focused cardiac ultrasound in term parturients. Methods Forty parturients underwent focused cardiac ultrasound. Parasternal long‐axis, parasternal short‐axis, 4‐chamber and subcostal views were performed in the left‐lateral position and the supine position by a novice operator. All images were graded on the following scale: 1 = no image; 2 = poor and insufficient image; 3 = sufficient image quality; 4 = good image quality; 5 = perfect image quality. A cut‐off grade of three signified images sufficient for clinical decision‐making. Results Images sufficient for clinical decision‐making were obtained in all patients when including all imaging views. 37/40 (93 %) patients presented images of grade ≥ 4, whereas 10/40 (25%) patients had images of grade 5. Image grades were higher in the left lateral position (all P < 0.001). Parturients with a body mass index ≤ 30 kg/m 2 did not present different image grades than parturients with a higher body mass index ( P = 0.753). Subcostal views could not be obtained. Conclusion Focused cardiac ultrasound is feasible in the obstetric population and images of sufficient quality for clinical decision‐making were obtained in all parturients by an operator with limited experience.
Chronic pancreatitis (CP) is associated with a shortened life expectancy. Statins have anti-inflammatory properties and we aimed to evaluate the association between the use of statins and the risk of death, progression of CP, and pancreatic cancer in patients with CP.We carried out a nested case-cohort study and included patients with CP. We used claims of proton pump inhibitors as an active comparator. Patients with cirrhosis or cancer were excluded. We evaluated the exposure on the basis of pharmacy claims of statins. We used propensity score matching with a statins : nonstatins ratio of 1 : 1.A total of 4807 patients were eligible for propensity score matching; 33% were women and the mean (SD) age at cohort entry was 56 (10) years. During follow-up, a total of 2073 (43%) patients had died and the risk of death was significantly lower among patients using statins versus no statins among 678 matched patients [hazard ratio (HR) 0.64; 95% confidence interval (CI): 0.49-0.83]. Use of statins versus no statins was associated with decreased progression of CP, with an HR of 0.21 (95% CI: 0.17-0.26). Pancreatic cancer occurred in 117 (2.4%) patients and we found a lower risk of pancreatic cancer in statin-treated patients compared with no statins, with a HR of 0.21 (95% CI: 0.06-0.70).In this nationwide study, we found lower risks of mortality, disease progression, and pancreatic cancer in patients with CP using statins. The study is limited by its retrospective design, but supports the hypothesis that statins may affect the course of CP.
The authors conducted a randomized controlled clinical trial to evaluate the usefulness of perioperative manual evaluation of the response to train-of-four (TOF) nerve stimulation. A total of 80 patients were divided into four groups of 20 each. For two groups (one given vecuronium and one pancuronium), the anesthetists assessed the degree of neuromuscular blockade during operation and during recovery from neuromuscular blockade by manual evaluation of the response to TOF nerve stimulation. In the other two groups, one of which received vecuronium and the other pancuronium, the anesthetists evaluated the degree of neuromuscular blockade solely by clinical criteria. The use of a nerve stimulator was found to have no effect on the dose of relaxant given during anesthesia, on the need for supplementary doses of anticholinesterase in the recovery room, on the time from end of surgery to end of anesthesia, or on the incidence of postoperative residual neuromuscular blockade evaluated clinically. The median (and range of) TOF ratios recorded in the recovery room were 0.75 (0.33-0.96) and 0.79 (0.10-0.97) in the vecuronium groups monitored with and without a nerve stimulator, respectively. These ratios were significantly higher than those found in the pancuronium groups, which wre 0.66 (0.06-0.90) and 0.63 (0.29-0.95), respectively. However, no difference was found between the vecuronium and pancuronium groups in the number of patients showing clinical signs of residual neuromuscular blockade, as evaluated by the 5-s head-lift test.(ABSTRACT TRUNCATED AT 250 WORDS)
