Behçet’s disease (BD) is a chronic relapsing vasculitis with multifunctional pathogenesis. The mucocutaneous and ocular lesions are the commonest manifestations, but BD also affects the musculoskeletal, intestinal, cardiac, and central nervous system. BD therapy is based on the suppression of the inflammatory process, using immunomodulating and immunosuppressive agents. In selected cases, invasive procedures may be required. 相似文献

Background: Few electrocardiographic parameters beyond the QRS duration were studied with regard to the correlation with mechanical dyssynchrony. This study aims to analyze the correlation between electrocardiographic parameters and mechanical dyssynchrony in patients with symptomatic heart failure (HF) and left bundle branch block (LBBB). Methods: Patients with HF, ejection fraction ≤ 35%, and QRS interval ≥ 120 ms with a LBBB were prospectively studied. We analyzed the correlation between electrocardiographic parameters (QRS duration, R voltage in limb leads, S voltage in precordial leads, Sokolow and Cornell indexes, QRS axis deviation, and QRS notches in lateral and inferior leads) and mechanical dyssynchrony measured by tissue Doppler imaging (TDI). Results: A group of 50 patients were studied, 60% male, 78% with nonischemic cardiomyopathy, NYHA Class III–IV (86%), and ejection fraction of 0.22 ± 0.6. Intra‐ and interventricular dyssynchrony occurred in 68% and 74% of patients, respectively. The S amplitude in precordial leads and the Sokolow and Cornel indexes show a weak correlation with the degree of dyssynchrony. In the patients with QRS notching in the lateral and inferior leads, we observed significantly greater prevalence of intraventricular dyssynchrony, with sensitivity and specificity of 85% and 56%, respectively, for notches in lateral leads. The QRS duration presents moderate correlation with the degree of both intraventricular (r = 0.48) and interventricular dyssynchrony (r = 0.46). Conclusion: The following electrocardiographic parameters were related to the degree of mechanical dyssynchrony: QRS duration and notches in QRS. In addition, the patients tend to have highest S amplitude in precordial leads. Ann Noninvasive Electrocardiol 2011;16(1):41–48 相似文献

In brief: Using data on 1,091 North Carolina high school wrestlers during 49 team-seasons, the authors attempted to relate the number, type, and severity of wrestling injuries to factors such as mat surfaces, endurance exercises, weight- reducing methods, protective equipment, and coaching experience. Most of the 248 injuries were minor, causing little time loss, but 57 (23%) were so severe that athletes missed an entire season. Possible contributory factors were inappropriate endurance training shoes, infrequent headgear use during practice, less than optimum wrestler-to-coach ratios, and potentially dangerous weight-reduction methods. 相似文献

The sternoclavicular (SC) joint can incur significant injuries. These injuries are often subtle, and, without a high index of suspicion, hard to diagnose. However, specific diagnostic methods can help clarify the extent of injury, and relatively straightforward treatment protocols can help resolve all but the most severe injuries. Two areas of concern are physeal injuries and posterior dislocations. In children and young adults, injuries of the SC joint must be considered physeal fractures until proven otherwise. Disastrous complications of posterior SC dislocations have been reported, but detecting vascular compromise or other serious sequelae will help minimize their occurrence. 相似文献

Aims: To investigate the thermal spread achieved in porcine liver when using an optimised radiofrequency ablation protocol and correlate findings with the effects seen in ex vivo great saphenous vein (GSV), in order to justify clinical use with the new treatment protocol.Material and methods: Porcine liver and GSV sections were treated with radiofrequency-induced thermotherapy (RFiTT) using the following settings: 20 W at 1?s/cm (linear endovenous energy density; LEED 20 J/cm), 18 W at 1?s/cm (LEED 18 J/cm), 18 W at 3?s/cm (LEED 54 J/cm), 6 W interrupted pull-back 6?s stationary every 0.5?cm (LEED 72 J/cm). Thermal spread in the liver was measured via digital imaging. GSV sections were sent to an independent laboratory for histological analysis. Previous work suggests a thermal spread of?>0.65?mm in liver correlates with transmural thermoablation of a GSV.Results: Parameters giving a LEED of 72 J/cm produced the best results, with a clear transmural effect in the GSV and maximal thermal spread of 1.65?mm, without excessive thermal damage or carbonisation in the ablation tract.Conclusions: Our porcine liver model correlated well with histological findings and was representative of the thermoablative effects observed in the GSV wall treated with RFiTT. Clinical investigations are now being carried out to investigate the efficacy of this protocol in the clinical setting. 相似文献
