Epiploic appendagitis and omental infarction are benign self-limiting conditions that are more frequent than generally assumed.
Both disorders frequently mimic symptoms of an abdominal surgical emergency, often leading to clinical misdiagnosis of appendicitis
or diverticulitis. Because a misdiagnosis can result in an unnecessary laparotomy, a correct diagnosis is of great importance.
Ultrasound and computed tomography can be used to make a reliable diagnosis. This pictorial essay illustrates the various
ultrasonographic and computed tomographic appearances of epiploic appendagitis and omental infarction and focuses on their
radiologic differential diagnoses and pitfalls.

Postoperative analgesia: pain by choice? The influence of patient attitudes and patient education 总被引:3,自引:0,他引:3
Postoperative pain control can be unsatisfactory for a variety of reasons, including patients' attitudes towards pain treatment itself. To assess patients' expectations and their influence on postoperative analgesia, as well as the prevalence of pain following common gynaecological surgery, a prospective study was performed in 166 patients with either adbominal hysterectomy, mastectomy, laparoscopy or uterine curettage. After a first postoperative period with routine on-demand analgesia, a nurse specialised in pain treatment discussed the purposes and risks of pain treatment with the patients and cared for these patients in the second, subsequent study period. Following this discussion, 30 of 40 patients refusing analgesics in the first study period agreed to be given pain medication. In the groups with hysterectomy or mastectomy, pain control improved in the second postoperative period, even though the doses of analgesics administered were generally lower. Education of patients regarding the aims and risks of pain therapy is an essential part of pain control and can lead to an improvement of postoperative analgesia. 相似文献

Since the end of the 2nd World War, Japan has seen quite rapid socioeconomical development. With this development the physical size of Japanese children has increased, but the final size, especially the stature, is still shorter than that of Americans or Europeans. Bone maturation velocities were compared among Japanese and Chinese children and adolescents aged 7 to 18 (in 1986) and English TW2-subjects, using the TW2 method. Asian children and adolescents may have a different tempo of skeletal maturation during pubertal growth from that of English children and adolescents. This, probably genetic, difference in the tempo of skeletal maturation, especially that of RUS, between Japanese and English during pubertal growth may be one of the main causes of the final difference in the stature of the two groups. 相似文献

BACKGROUND: Our objective was to determine the cost-effectiveness of a comprehensive, risk-based triage system, composed of multiple critical pathways, with the use of early myocardial perfusion imaging (MPI) in low-risk patients. We found previously that a chest pain evaluation system that uses MPI in low-risk patients was safe and effective, but the cost-effectiveness of this approach was not studied. METHODS AND RESULTS: We compared two groups. The Acute Cardiac Team (ACT) group (n = 874) was assigned prospectively to 1 of 4 risk levels by emergency department (ED) physicians. Level 1, 2, and 3 patients were admitted; level 4 patients were evaluated in the ED. Level 3 and 4 patients underwent ED MPI. The control group (n = 713) represented consecutive patients evaluated in the prior year according to standard care and assigned retrospectively to an ACT level based on the presenting electrocardiographic and clinical data. Record and hospital administrative data were assessed for clinical variables, outcomes, lengths of stay, and all expenses incurred within 30 days of the index visit. The baseline characteristics of the two groups were similar, including age, sex, myocardial infarction prevalence, and 30-day revascularization rates within each level or between the two groups. Mean costs per encounter were reduced for the ACT patients for each level, which was significant when all patients were compared ($5,030 +/- $7,081 vs $6,044 +/- $10,432, P =.02). Use of MPI in the low-risk patients was associated with reduced costs (level 3, $4,958 +/- $4,948 vs $5,051 +/- $7,036; level 4, $1,529 +/- $2,664 vs $1,794 +/- $6,854) and was associated with a significantly lower angiography rate and shorter length of stay. CONCLUSIONS: Implementation of a comprehensive strategy for chest pain evaluation and triage reduced overall costs for patients with chest pain on presentation. Acute MPI in the ED setting did not increase net cost. 相似文献

目的通过PET-CT明确18F-氟脱氧葡萄糖在主动脉壁粥样硬化斑块中摄取程度,探讨其临床价值。方法60例受检者,包括正常对照者6例,大动脉粥样硬化病例54例。测定主动脉壁粥样硬化部位标准化摄取值(SUV)和CT值,并依据CT值将54例主动脉壁局部18F-FDG高摄取的动脉粥样硬化病例分成3组,软斑块组CT值小于60HU,中等斑块组CT值介于60 ̄100HU之间,钙化斑块组CT值大于100HU。第4组为正常对照组。结果软斑块组42个测量部位的平均SUV为1.553±0.486;中等斑块组30个测量部位的平均SUV为1.393±0.296;钙化斑块组36个测量部位的平均SUV为1.354±0.189;正常对照组33个测量部位的平均SUV为1.102±0.141。多组之间比较差异具有统计学意义(F=678.909,P=0.000);正常组与各斑块组比较差异具有统计学意义。结论18F-FDG在主动脉粥样硬化斑块中具有不同程度的摄取,其中软斑块对18F-FDG的摄取最高,提示18F-FDG PET-CT是诊断不稳定性主动脉粥样硬化斑块的有价值方法。 相似文献
