BACKGROUND: Previous reports of laparoscopic cholecystectomy (LC) in patients with biliary pancreatitis suggested increased operative difficulty, high rates of conversion, and greater morbidity and mortality. METHODS: Between 1990 and 1997, LC was performed for biliary pancreatitis in 63 patients (Group I) and for other causes in 829 patients (Group II). RESULTS: Patients with biliary pancreatitis were significantly older (median age 57 vs 50 years, p = 0.009), with greater co-morbidity (ASA III/IV 24% vs 11%, p = 0.008). The groups were comparable with respect to the frequency of previous abdominal operations, acute inflammation of the gallbladder, and the frequency of bile duct calculi detected by intraoperative cholangiography. Moderate to severe adhesions involving the gallbladder were significantly more frequent in patients with biliary pancreatitis (46% vs 29%, p = 0.004). No significant differences were observed between the two groups with respect to intraoperative (1.5% Group I vs 6.0% Group II, p = 0.109) or postoperative complications (10% vs 8%, p = 0.426), conversion rate (0 vs 2.7%, p = 0.181), or duration of operation (median 92 vs 85 min, p = 0.33). CONCLUSION: Despite increased age and co-morbidity and more frequent adhesions, our data showed no evidence that intraoperative or postoperative complications were more frequent in patients with biliary pancreatitis than in other patients undergoing LC.
Our primary objective was to assess diagnostic accuracy for acute otitis media (AOM) relative to the criterion standard established by the United States Agency for Healthcare Research and Quality: middle-ear effusion (MEE) plus onset in the past 48 h of signs or symptoms of middle-ear inflammation. A secondary objective was to assess the potential reduction in antibiotic usage that could be achieved if clinicians managed AOM according to a consensus guideline developed by the New York Region Otitis Project (NYROP). A convenience sample of primary care practitioners were surveyed after diagnosing AOM in 135 children aged 0.3-11.8 years (median 2.4 years). Clinicians expressed high certainty for AOM diagnosis in 122/135 episodes (90%). The prevalence of true AOM was 70% with a positive predictive value for high certainty of 76%. Of the 40 false-positive diagnoses, 35 did not have MEE and 5 did not have acute signs or symptoms. The relative risk for receiving an antibiotic was 1.50 times higher when clinicians expressed certainty (P=0.005), which produced 31/120 (26%) potentially unnecessary antibiotic prescriptions. Initial antibiotics would not have been prescribed for 29% of episodes using the NYROP guidelines. More judicious use of antibiotics may result if clinicians deferred initial therapy in children without definitive AOM, particularly when the presence of MEE is uncertain.
BACKGROUND: Nontoxic heat shock protein (HSP) inducer compounds open up promising therapeutic possibilities by activating one of the natural and highly conserved defense mechanisms of the organism. AIMS: In the present experiments, we examined the effects of a HSP coinducer drug-candidate, BRX-220, on the cholecystokinin-octapeptide (CCK)-induced acute pancreatitis in rats. METHODS: Male Wistar rats weighing 240 to 270 g were divided into two groups. In group B, 20 mg/kg BRX-220 was administered orally, followed by 75 microg/kg CCK subcutaneously three times, after 1, 3, and 5 h. This whole procedure was repeated for 5 d. The animals in group slashed circleB received physiological saline orally instead of BRX-220, but otherwise the protocol was the same as in group B. The rats were exsanguinated through the abdominal aorta 12 h after the last administration of CCK. We determined the serum amylase activity, the plasma trypsinogen activation peptide concentration, the pancreatic weight/body weight ratio, the DNA and total protein contents of the pancreas, the levels of pancreatic HSP60 and HSP72, the activities of pancreatic amylase, lipase, trypsinogen, and free radical scavenger enzymes (superoxide dismutase, catalase, and glutathione peroxidase), the degree of lipid peroxidation, protein oxidation, and the reduced glutathione level. Histopathological investigation of the pancreas was also performed in all cases. RESULTS: Repeated CCK treatment resulted in the typical laboratory and morphological changes of experimentally induced pancreatitis. The pancreatic levels of HSP60 and HSP72 were significantly increased in the animals treated with BRX-220. In group B, the pancreatic total protein content and the amylase and trypsinogen activities were significantly higher vs. group slashed circleB. The plasma trypsinogen activation peptide concentration, and the pancreatic lipid peroxidation, protein oxidation, and the activity of Cu/Zn-superoxide dismutase were significantly decreased in group B vs. group slashed circleB, whereas the glutathione peroxidase activity was increased. The morphological damage in group B was significantly lower than that in group slashed circleB. CONCLUSION: The HSP coinducer BRX-220, administered for 5 d, has a protective effect against CCK-induced acute pancreatitis.
