Introduction: Features of spiral CT (SCT) — fast scanning, dynamic injection of contrast allowing optimal vessel opacification, and supplemental multiplanar imaging — promises to provide increased accuracy in the diagnosis of acute and non acute thoracic vascular disease. Recent work demonstrating the cost effective triage of hemodynamically stable patients after blunt chest trauma for angiography based on dynamic CT findings has prompted an investigation into the accuracy of SCT in this clinical setting. Methods: A retrospective review of all patients seen in the emergency department over the period of one year for aortic, thoracic, or blunt chest trauma evaluation was performed (74 patients) and all SCT scans available were reviewed and data reformatted for optimal delineation of pathology using maximum intensity projection and multiplanar reformation. The accuracy and predictive positive and negative values of SCT were calculated with respect to angiography, surgical, and/or clinical follow up evaluation. Results: Twenty three (31%) patients went directly to angiography owing to mediastinal widening on chest film and hemodynamic instability, of which four were positive and required emergent surgery. Seven hemodynamically stable patients (9%) had noncontrast SCT owing to mediastinal widening on chest film, all of which had angiography with none having great vessel trauma. Fourty four hemodynamically stable patients (60%) had contrast enhanced SCT (ceSCT), of which five (11%) were abnormal and underwent angiography, four of these were positive for aortic damage, one for a subclavian artery laceration. Of the remaining 39 patients who had normal ceSCT; five had angiography, all of which were normal. Of the remaining 34 patients that had normal ceSCT none had adverse outcome on clinical follow-up, minimum of 12 months. Conclusion: The predictive positive value for aortic trauma of ceSCT in blunt trauma is 80%, with a predictive negative value of 100%, indicating that it is feasible for SCT to be a first line exam in blunt chest trauma in the future. 相似文献

OBJECTIVE--It was hypothesised that the endometrium might act as a reservoir for candida, thus infecting the vagina as the endometrium is shed during menstruation. DESIGN--A prospective study of women with recurrent vulvo-vaginal candidiasis. The endometrium was sampled and cultured for candida species. SETTING--Central London STD clinic. SUBJECTS--26 women were enrolled, of whom 20 completed the study. RESULTS--One patient had a positive endometrial culture for candida species, the isolate being Candida krusei. CONCLUSIONS--The endometrium is not a common resevoir for candida species and therefore, infection at this site is an unlikely cause of recurrent vaginal candidiasis. 相似文献

An in vivo study was undertaken during hypothermic (28 degrees C) cardiopulmonary bypass to compare oxygenator exhaust capnography as a means of estimating arterial carbon dioxide tension (PaCO2) with bench blood gas analysis. A total of 123 pairs of measurements were made in 40 patients. Oxygenator exhaust capnographic measurements systematically underestimated PaCO2 measured by a bench blood gas analyzer. During the cooling and stable hypothermic phases of cardiopulmonary bypass, the relationship was reasonably accurate, but became far more variable during rewarming. Oxygenator exhaust capnography could be used as an inexpensive means of continuously monitoring PaCO2 during the cooling and stable hypothermic phases of cardiopulmonary bypass but should not be used during rewarming. 相似文献

Jugular venous desaturation following cardiac surgery 总被引:2,自引:2,他引:0
Twenty-two patients undergoing coronary artery bypass surgery underwent
postoperative measurement and recording of jugular venous oxyhaemoglobin
saturation (SjO2) with desaturation defined as a value of less than 50% for
5 min or longer. Fifteen of the 22 patients monitored experienced
desaturations. An average of four episodes were experienced by those 15
patients (range 1-14). The mean duration of a single episode was 46 (range
5-212) min whilst mean total duration of desaturation was 175 (range 5-570)
min. The mean duration of desaturation in the 15 patients, expressed as a
percentage of monitored time, was 21.1% (range 0.58%-61.96%). SjO2
desaturation, possibly indicating cerebral hypoperfusion, occurs in the
early post-operative period following cardiac surgery.

OBJECTIVE: To investigate the relation between psychiatric distress and road rage, paying particular attention to the potential link between psychiatric illness and frequent involvement in serious forms of road rage. METHOD: This study reports data on road rage involvement, demographic characteristics, and mental health for a representative sample of 2610 adults in Ontario. The mental health indicator was the 12-item General Health Questionnaire. RESULTS: A cluster analysis revealed 5 distinct groups of people affected by road rage. The most serious offenders (referred to hereafter as the hard core road rage group), representing 5.5% of those affected, exhibited frequent involvement in the most severe forms of road rage and were the most likely (27.5%) to report psychiatric distress. CONCLUSIONS: Road rage, particularly experiences of victimization, is related to psychiatric distress. Evidence of psychiatric distress was highest among hard core road rage perpetrators, individuals noted for frequent involvement in serious aggressive and violent conduct. Further research is needed on violence and road rage and its link to mental health. 相似文献

The additive benefit of hypnosis and cognitive-behavioral therapy in treating acute stress disorder 总被引:3,自引:0,他引:3
Bryant RA Moulds ML Guthrie RM Nixon RD 《Journal of consulting and clinical psychology》2005,73(2):334-340
This research represents the first controlled treatment study of hypnosis and cognitive- behavioral therapy (CBT) of acute stress disorder (ASD). Civilian trauma survivors (N=87) who met criteria for ASD were randomly allocated to 6 sessions of CBT, CBT combined with hypnosis (CBT-hypnosis), or supportive counseling (SC). CBT comprised exposure, cognitive restructuring, and anxiety management. CBT-hypnosis comprised the CBT components with each imaginal exposure preceded by a hypnotic induction and suggestions to engage fully in the exposure. In terms of treatment completers (n=69), fewer participants in the CBT and CBT-hypnosis groups met criteria for posttraumatic stress disorder at posttreatment and 6-month follow-up than those in the SC group. CBT-hypnosis resulted in greater reduction in reexperiencing symptoms at posttreatment than CBT. These findings suggest that hypnosis may have use in facilitating the treatment effects of CBT for posttraumatic stress. 相似文献
