Infarction of the lesser omentum is an infrequent occurrence and is unfamiliar to most clinicians. Patients with this condition present with insidious epigastric pain, peritonitis on examination, and a normal white blood cell count. The computed tomographic scan reveals a focal ill-defined inflammatory mass with attendant fat stranding along the lesser curve of the stomach. In most patients, the diagnosis is secured at operation, although analgesics alone might be sufficient for management of this benign inflammatory condition. We present a case with the classic findings that was managed laparoscopically. Greater familiarity with focal infarction of lesser omental fat might lead to more nonoperative management in the future. 相似文献

We studied the effects of gonadol steroid implants on catecholamine levels in the brain of ovariectomized female toadfish (Opsanus tau L.). Control values for dopamine (DA), norepinephrine (NE) and epinephrine (EPI) in the brain were 2181 +/- 226, 1112 +/- 80 and 6.5 +/- 2.02 ng/g, respectively. Compared to controls, 17 beta-estradiol decreased brain levels of DA to 547 +/- 261, and dihydrotestosterone decreased DA to 444 +/- 290 ng/g (P less than 0.001). Furthermore, dihydrotestosterone increased brain levels of EPI to 15.0 +/- 4.7 ng/g. The steroids had no effect on brain levels of NE. These results suggest a role for both androgens and estrogens in regulating brain levels of DA and EPI in toadfish. 相似文献

Introduction
Smoking is associated with a higher incidence of post-lung transplantation complications and mortality. Prior to inclusion on the lung transplant waiting list in the Czech Republic, patients are supposed to be tobacco free for at least 6 months. Our aim was to determine the prevalence of smoking, validated by urinary cotinine, among patients post lung transplantation and prior to inclusion on the transplant waiting list.Methods
Between 2009 and 2012, we conducted a cross-sectional survey of urinary cotinine to assess tobacco exposure in 203 patients in the Lung Transplant Program in the Czech Republic. We measured urinary cotinine in 163 patients prior to inclusion on the transplantation waiting list, and 53 patients post bilateral lung transplantation.Results
15.1% (95% CI 0.078 to 0.269) of all lung transplant recipients had urinary cotinine levels corresponding to active smoking; and a further 3.8% (95% CI 0.007 to 0.116) had borderline results. Compared to patients with other diagnoses, patients with COPD were 35 times more likely to resume smoking post- transplantation (95% CI 1.92 to 637.37, p-value 0.016). All patients who tested positive for urinary cotinine levels were offered smoking cessation support. Only one Tx patient sought treatment for tobacco dependence, but was unsuccessful.Conclusion
Smoking resumption may be an underrecognized risk for lung transplantation recipients, particularly among patients with chronic obstructive pulmonary disease. More rigorous screening, as well as support and treatment to stop smoking among these patients are needed. 相似文献69.

INTRODUCTION
The aim of this study was to evaluate temporal trends in the prevalence of primary total hip and knee replacements (THRs and TKRs) throughout the Trent region from 1991 to 2004.PATIENTS AND METHODS
The Trent Regional Arthroplasty Study records details of primary THR and TKR prospectively and data from the register were examined. Age and gender population data were provided by the Office for National Statistics.RESULTS
A total of 26,281 THRs and 23,606 TKRs were recorded during this period. Analysis showed that females had an increased incidence rate ratio (IRR) for both primary THR (IRR = 1.29; 95% CI 1.26–1.33; P < 0.001) and TKR (IRR = 1.17; 95% CI 1.14–1.20; P < 0.001). Patients aged 74–85 years had the largest IRR for both primary THR (IRR = 6.7; 95% CI 6.4–7.0; P < 0.001) and TKR (IRR = 15.3; 95% CI 14.4–16.3; P < 0.001).CONCLUSIONS
The prevalence of primary TKR increased significantly over time whereas THR remained steady in the Trent region between 1991 and 2004. 相似文献70.
