起搏治疗遗传性长QT间期综合征23例

目的:评价VVI起搏治疗遗传性长QT综合征的疗效. 方法:对23例有尖端扭转性室速发作,且经正规药物治疗无效或无法耐受的遗传性长QT综合征患者,植入了VVI起搏器.随访这23例患者术后心电图及心脏事件发生率. 结果:QT间期平均值由术前(638.0±55.7)ms缩短至术后的(471.3±48.9)ms,QTc平均值为由0.627±0.07缩短至0.519±0.06.心脏事件的发生率由术前的(0.353±0.46)次/年降至术后(0.111±0.24)次/年,(P=0.039).其中77.5%的患者随访期间无晕厥或猝死等心脏事件发生.90.91%患者存活.2例患者因尖端扭转性室速恶化为室颤抢救无效死亡. 结论:VVI起搏治疗可以有效地减少长QT综合征患者恶性心律失常的发生,是治疗长QT综合征的重要方法之一.     

劳累性心绞痛患者冠脉病变和抑郁障碍相关性分析

目的比较劳累性心绞痛患者抑郁障碍与冠状动脉粥样硬化程度的相关性，以进一步明确两者之间关系。方法将146名劳累性心绞痛患者根据汉密尔顿抑郁量表评分分为无抑郁症状组、可疑抑郁症状组、明确抑郁症状组。比较三组冠脉Gensini积分。结果3组之间Germini积分值存在统计学差异（P〈0．05）。HAMD量表评分与Gensimi评分成正相关（r=0．244，P〈0.01）。结论劳累性心绞痛患者冠脉粥样硬化程度与抑郁障碍程度成正相关，抑郁障碍对冠脉粥样硬化的发展可产生不良影响。

Subjective leisure experiences of older Australians

Background:  Previous studies into leisure have employed methodologies that may understate the significance of experiential components. This exploratory study investigated the leisure experiences of retired Australians over 65 years of age.
Methods:  Five semistructured interviews were used to explore the leisure experience of older people from metropolitan Adelaide. Data were coded and analysed thematically.
Results:  Relaxation and engrossment emerged as commonly expressed experiences, yet were found to emerge as a result of engagement in occupations predefined as leisure. Experiences of freedom from both necessary duties and a sense of obligation were discussed as potential determinants of leisure consciousness.
Practice implications:  This study highlights a need for therapists to actively access clients' subjective leisure experiences to enable engagement in personally meaningful leisure occupations.     

Similar incidence of hypotension with combined spinal-epidural or epidural alone for knee arthroplasty

BACKGROUND: We hypothesized that the incidence of hypotension during total knee replacement (TKR) surgery is lower in patients given combined spinal-epidural (CSE) anesthesia vs those receiving epidural anesthesia alone. METHODS: In a prospective study, 80 American Society of Anesthesiologists I-II patients (aged 40-80 yr), undergoing elective TKR surgery were randomly assigned to either CSE anesthesia (CSE, n = 40) or epidural anesthesia alone (Epidural, n = 40). Hemodynamic measurements included oscillometric mean arterial blood pressure (MAP), heart rate (HR), and cardiac index (CI) as determined by thoracic bioimpedance; systemic vascular resistance (SVR) was calculated. Our primary endpoint (outcome) was the number of hypotension episodes (defined as MAP < 70 mmHg). RESULTS: Using univariate analysis, we found no differences between the groups in regards to MAP, HR, CI, or SVR during the perioperative period. The incidence of hypotension was similar in both groups (two patients in each group), as was the incidence of bradycardia (12 patients in CSE, 7 in Epidural; P = 0.2). There were no differences between groups in other hemodynamic measurements including CI and calculated SVR. Analgesia supplementation with fentanyl was more frequently required in the Epidural group (20 vs 6 patients - P = 0.03). CONCLUSION: Combined spinal-epidural anesthesia and epidural anesthesia alone during TKR surgery are associated with the same incidence of hypotension with statistically and clinically similar hemodynamic responses.     

Diagnosis of ligament rupture of the ankle joint: Physical examination, arthrography, stress radiography and sonography compared in 160 patients after inversion trauma

We prospectively enrolled 160 consecutive patients with inversion trauma of the ankle in a diagnostic protocol that included physical examination within 2 days and at 5 days after trauma, arthrography, stress radiography, and ultrasonography. 135 patients had pathological lateral ligament laxity on the later physical examination or lateral ligament rupture diagnosed on arthrography and they were operated on. 122 of these patients had ligament ruptures.

At clinical follow-up after a minimum of half a year, all of the patients who were not operated on had stable joints without signs of previous ligament ruptures.

Delayed physical examination at 5 days after the injury led to the highest overall sensitivity (96%) and specificity (84%) for the detection of a ligament rupture. Additional diagnostic procedures, at a considerable cost, yielded little additional information.
