Straight back syndrome (SBS) is a thoracic deformity with absence of upper thoracic spine kyphosis and heart compression.
The anatomic abnormity of SBS may raise the difficulty of introcardial operation and increase the complicated risk of intervention
performance. Here we report a case of SBS with complicated transseptal puncture during intervention catheter ablation of atrial
fibrillation. 相似文献

Effect of early and late antibiotic treatment in experimental acute pancreatitis in rats 总被引:1,自引:0,他引:1

Background The clinical course in acute necrotizing pancreatitis is mainly determined by bacterial infection of pancreatic and peripancreatic
necrosis. The effect of two antibiotic regimens for early and late treatment was investigated in the taurocholate model of
necrotizing pancreatitis in the rat.
Materials and methods Seventy male Wistar rats were divided into five pancreatitis groups (12 animals each) and a sham-operated group (10 animals).
Pancreatitis was induced by intraductal infusion of 3% taurocholate under sterile conditions. Animals received two different
antibiotic regimes (20 mg/kg imipenem or 20 mg/kg ciprofloxacin plus 20 mg/kg metronidazole) early at 2, 12, 20, and 28 h
after induction of pancreatitis or late at 16 and 24 h after induction of pancreatitis or no antibiotics (control). Animals
were examined after 30 h for pancreatic and extrapancreatic infection.
Results Early and late antibiotic treatment with both regimes could significantly reduce pancreatic infection from 58 to 8–25%. However,
extrapancreatic infection was only reduced by early antibiotic therapy. While quinolones also reduced bacterial counts in
small and large bowel, imipenem did not.
Conclusions In our animal model of necrotizing pancreatitis, early and late treatment with ciprofloxacin/metronidazole and imipenem reduce
bacterial infection of the pancreas. Extrapancreatic infection, however, is reduced significantly only by early antibiotic
treatment. The effectivity of early antibiotic treatment in the clinical setting should be subject to further investigation
with improved study design and sufficient patient numbers. 相似文献

BACKGROUND: Although there is increasing evidence suggesting that the vagus nerve functions as a connector between the nervous and immune systems in animals, little is known about the role of the vagus nerve in postoperative acute phase response in humans. MATERIALS AND METHODS: The extent of fever and acute phase protein response and the production of inflammatory cytokine during the early postoperative period were compared among the patients who had undergone total gastrectomy including truncal vagotomy (n = 13), those having distal gastrectomy with division of vagal branches (n = 14), and the patients with vagal nerve preserving gastrectomy (n = 12). RESULTS: There was no significant difference in serum levels of C-reactive protein, alpha-1-antirypsin, and interleukin-6 among the three groups. Also, postoperative maximum body temperature was similar. CONCLUSIONS: Vagotomy did not influence acute phase response after gastric cancer surgery. A multipathway mechanism for acute phase response including the induction of fever is suggested. 相似文献

Background
Movement control dysfunction [MCD] reduces active control of movements. Patients with MCD might form an important subgroup among patients with non specific low back pain. The diagnosis is based on the observation of active movements. Although widely used clinically, only a few studies have been performed to determine the test reliability. The aim of this study was to determine the inter- and intra-observer reliability of movement control dysfunction tests of the lumbar spine. 相似文献999.
This study uses the Taiwan Healthcare Indicator Series (THIS) system as an example to examine which determinants would improve
performance by sharing indicators from a management perspective. This study population included all 227 hospitals participating
in the THIS system in 2006. A structured questionnaire was sent to the director who was responsible for the THIS system via
electronic mail. A total of 111 responses were returned by February 10, 2006. Questions included current implementation and
impacts of the system. Hierarchical regression models were performed to identify which variables were significantly associated
with performance improvement, adjusted for hospital characteristics. Four variables significantly associated with implementing
the THIS system to improve performance were ‘senior management support,’ ‘benchmarking,’ ‘making departments improve the underperforming
indicators and report the improvement results in performance management meetings,’ and ‘integration with the National Health
Insurance payment regulations’. This study contributes substantially to the evidence base about what works to improve performance
by information sharing. Although information sharing is the basis of efforts to improve performance, senior management support
and how to effectively apply the information are the most important determinants of performance enhancement. 相似文献

Introduction Obese individuals may have normal insulin–glucose homeostasis, insulin resistance, or diabetes mellitus. Whereas gastric bypass
cures insulin resistance and diabetes mellitus, its effects on normal physiology have not been described. We studied insulin
resistance and β-cell function for patients undergoing gastric bypass.
Methods One hundred thirty-eight patients undergoing gastric bypass had fasting insulin and glucose levels drawn on days 0, 12, 40,
180, and 365. Thirty-one (22%) patients with diabetes mellitus were excluded from this analysis. Homeostatic model of assessment
was used to estimate insulin resistance, insulin sensitivity, and β-cell function. Based on this model, patients were categorized
as high insulin resistance if their insulin resistance was >2.3.
Results Body mass index did not correlate with insulin resistance. Forty-seven (34%) patients were categorized as high insulin resistance.
Correction of insulin resistance for this group occurred by 12 days postoperatively. Sixty (43%) patients were categorized
as low insulin resistance. They demonstrated an increase of β-cell function by 12 days postoperatively, which returned to
baseline by 6 months. At 1 year postoperatively, the low insulin resistance group had significantly higher β-cell function
per degree of insulin sensitivity.
Conclusions Adipose mass alone cannot explain insulin resistance. Severely obese individuals can be categorized by degree of insulin resistance,
and the effect of gastric bypass depends upon this preoperative physiology. 相似文献
