ObjectiveThe effect of early intravenous (IV) beta-blockers (BBs) administration in patients undergoing primary percutaneous coronary intervention (pPCI) on ST-segment deviation is unknown. We undertook a prespecified secondary analysis of the Early Beta-blocker Administration before primary PCI in patients with ST-elevation Myocardial Infarction (EARLY-BAMI) trial to investigate the effect of early IV BB on ST-segment deviation.MethodsThe EARLY-BAMI trial randomised patients with ST-elevation myocardial infarction (STEMI) to IV metoprolol (2×5 mg bolus) or matched placebo before pPCI. The prespecified outcome, evaluated by an independent core laboratory blinded to study treatment, was the residual ST-segment deviation 1 hour after pPCI (ie, the percentage of patients with >3 mm cumulative ST deviation at 1 hour after pPCI).ResultsAn ECG for the evaluation of residual ST-segment deviation 1 hour after pPCI was available in 442 out of 683 randomised patients. The BB group had a lower heart rate after pPCI compared with placebo (71.2±13.2 vs 74.3±13.6, p=0.016); however, no differences were noted in the percentages of patients with >3 mm cumulative ST deviation at 1 hour after pPCI (58.6% vs 54.1%, p=0.38, in BB vs placebo, respectively) neither a significant difference was found for the percentages of patients in each of the four prespecified groups (normalised ST-segment; 1–3 mm; 4–6 mm;>6 mm residual ST-deviation).ConclusionsIn patients with STEMI, who were being transported for primary PCI, early IV BB administration did not significantly affect ST-segment deviation after pPCI compared with placebo. The neutral result of early IV BB administration on an early marker of pharmacological effect is consistent with the absence of subsequent improvement of clinical outcomes.

Background The impact of intravenous (IV) beta-blockers before primary percutaneous coronary intervention (PPCI) on infarct size and clinical outcomes is not well established. Objectives This study sought to conduct the first double-blind, placebo-controlled international multicenter study testing the effect of early IV beta-blockers before PPCI in a general ST-segment elevation myocardial infarction (STEMI) population. Methods STEMI patients presenting

The ligamentous reconstruction according to Eaton and Littler (7) was designed to restore the stability of the carpometacarpal joint of the thumb. We evaluated the patients' satisfaction after an Eaton and Littler-procedure as well as possible risk factors in the development of thumb basal joint instability. A retrospective chart review and clinical assessment or telephone survey are executed in 33 patients, with a mean follow-up of 7 years. Only 45% of the patients were satisfied. Within the group of clinical assessed patients, there were significant differences in thumb function comparing operated with not operated side. Overall joint hypermobility can be a contributing factor for this thumb basal joint instability, but has no effect on the outcome after an Eaton-Littler procedure.

Background: Although intracoronary abciximab failed to improve prognosis compared with intravenous route in unselected ST-segment elevation myocardial infarction (STEMI) patients, little is known about the role of intracoronary abciximab in diabetic patients.Objectives: To evaluate the efficacy of intracoronary abciximab administration in diabetic patients with STEMI undergoing primary percutaneous coronary intervention (PCI).Methods: Reperfusional and clinical outcomes of intracoronary abciximab compared with intravenous bolus abciximab according to diabetic status were evaluated in a pooled analysis of five randomized trials including 3158 STEMI patients. The primary clinical endpoint of the study was the composite of death or reinfarction at 30-day follow-up.Results: Among 584 diabetic patients (18.5%), the composite of death or reinfarction was significantly reduced with intracoronary abciximab compared to intravenous abciximab (4.7% vs. 8.8%; rate ratio [RR], 0.50; 95% confidence intervals [CI], 0.26-0.99; p = 0.04), driven by numerically lower deaths (3.7% vs. 6.4%; RR, 0.56; 95% CI, 0.26-1.20; p = 0.13). Moreover, a significant reduction in definite or probable stent thrombosis was observed in patients receiving intracoronary abciximab (1% vs. 3.5%; RR, 0.27; 95% CI, 0.07-0.99; p = 0.04). Although formal tests for interaction were not significant, no clinical benefit was apparent in the cohort of STEMI patients without diabetes (n = 2574).Conclusions: In diabetic patients with STEMI undergoing primary PCI, intracoronary abciximab may improve clinical outcomes as compared with standard intravenous use. These findings require confirmation in a dedicated randomized trial. (C) 2015 Elsevier Inc. All rights reserved.

Aims: Interleukin-6 receptor (IL-6R) signalling has been suggested to play a causal role in the development and outcome of coronary heart disease (CHD). The aim of this study was to investigate the association of sIL-6R levels with myocardial reperfusion after percutaneous coronary intervention (PCI) for acute ST-elevated myocardial infarction (STEMI).Methods: Blood was sampled from 70 patients presenting with STEMI at 6 different time-points (baseline, post-PCI, t = 1 h, t = 6 h, t = 24 h, t = 2w). Coronary angiograms post-PCI were analysed for myocardial blush grade (MBG) as indicator of myocardial reperfusion. Serum IL-6 and sIL-6R were measured using IL-6 and sIL-6R enzyme-linked immunosorbent assays (ELISA).Results: sIL-6R levels fluctuated biphasic during the two weeks after STEMI. Reduced MBG was associated with a larger change in sIL-6R levels between baseline and post-PCI compared to optimal MBG (-13.40; SEM 2.78 ng/ml vs -1.99; SEM 2.35 ng/ml, respectively; p Conclusions: sIL-6R levels fluctuate biphasic during the two weeks after MI with larger changes and increased IL-6/sIL-6R ratio in patients with reduced MBG. Further research is needed to increase our understanding of the possible causality of these associations. (C) 2015 Elsevier Ltd. All rights reserved.

Item does not contain fulltext AIMS: To investigate the optimal periprocedural antithrombotic strategy in patients on long-term oral anticoagulation (OAC) who require percutaneous coronary intervention with stenting. METHODS AND RESULTS: The WOEST study was a randomised controlled trial which recruited 573 patients on long-term OAC who underwent PCI. The periprocedural treatment strategy was left to the operator's discretion. To assess the safety and feasibility of uninterrupted oral anticoagulation (UAC) and bridging therapy (BT), bleeding complications and MACCE were assessed in patients treated according to UAC (n=241) and BT (n=322) regimen. After 30 days, as well as after one year, there were no significant differences in bleeding complications (HR 1.14, 95% CI: 0.77-1.69, p=0.51, and HR 1.26, 95% CI: 0.94-1.69, p=0.12, respectively) and MACCE. MACCE tended to be less frequent in the UAC group (respectively HR 0.48, 95% CI: 0.15-1.51, p=0.21, and HR 0.72, 95% CI: 0.46-1.14, p=0.16). Additionally, adjustment with a propensity score revealed no significant differences. Periprocedural INR was not associated with bleeding or MACCE. CONCLUSIONS: In the WOEST study, UAC was not associated with an increase of bleeding or MACCE compared to bridging therapy. This is the largest study up to now to support the current guidelines. The WOEST trial is registered with ClinicalTrials.gov, number NCT00769938.

Several studies have highlighted the prognostic role of preprocedural Thrombolysis In Myocardial Infarction (TIMI) flow in the infarct-related artery (IRA) in patients with ST-segment elevation myocardial infarction (STEMI). However, the impact of preprocedural IRA occlusion in patients with diabetes with STEMI has been insufficiently studied. The aim of this study was to evaluate the effects of baseline IRA occlusion and diabetic status in patients with STEMI who underwent primary percutaneous coronary intervention by using data from a pooled analysis of randomized trials comparing intracoronary with intravenous abciximab bolus administration. A total of 3,046 patients with STEMI who underwent primary percutaneous coronary intervention were included. Diabetes was present in 578 patients (19%). The primary outcome was mortality after a median follow-up period of 375 days. Secondary end points were reinfarction and stent thrombosis. In patients without diabetes, IRA occlusion versus no occlusion was not associated with increased rates of mortality (4.3% vs 2.7%, p = 0.051) and reinfarction (3.3% vs 2.5%, p = 0.33). Patients with diabetes with IRA occlusion compared with those without occlusion showed higher rates of mortality (10.6% vs 4.6%, p = 0.01) and reinfarction (5.6% vs 2.1%, p = 0.03). Baseline IRA occlusion increased the rate of stent thrombosis in the nondiabetic (2.1% vs 1.0%, p = 0.04) and diabetic (3.2% vs 0.8%, p = 0.05) cohorts. Interaction analysis demonstrated that the risk for death and reinfarction was significantly increased when diabetes and IRA occlusion occurred concomitantly. In conclusion, patients with STEMI with diabetes and baseline IRA occlusion had disproportionately higher rates of death and reinfarction. Preprocedural IRA occlusion increased the risk for stent thrombosis, irrespective of diabetic status. (C) 2014 Elsevier Inc. All rights reserved.

Importance Metformin treatment is associated with improved outcome after myocardial infarction in patients with diabetes. In animal experimental studies metformin preserves left ventricular function. Objective To evaluate the effect of metformin treatment on preservation of left ventricular function in patients without diabetes presenting with ST-segment elevation myocardial infarction (STEMI). Design, Setting, and Participants Double-blind, placebo-controlled study conducted among 380 patients who underwent primary percutaneous coronary intervention (PCI) for STEMI at the University Medical Center Groningen, the Netherlands, between January 1, 2011, and May 26, 2013. Interventions Metformin hydrochloride (500 mg) (n = 191) or placebo (n = 189) twice daily for 4 months. Main Outcomes and Measures The primary efficacy measure was left ventricular ejection fraction (LVEF) after 4 months, assessed by magnetic resonance imaging. A secondary efficacy measure was the N-terminal pro-brain natriuretic peptide (NT-proBNP) concentration after 4 months. The incidence of major adverse cardiac events (MACE; the combined end point of death, reinfarction, or target-lesion revascularization) was recorded until 4 months as a secondary efficacy measure. Results At 4 months, all patients were alive and none were lost to follow-up. LVEF was 53.1% (95% CI, 51.6%-54.6%) in the metformin group (n = 135), compared with 54.8% (95% CI, 53.5%-56.1%) ( P = .10) in the placebo group (n = 136). NT-proBNP concentration was 167 ng/L in the metformin group (interquartile range [IQR], 65-393 ng/L) and 167 ng/L in the placebo group (IQR, 74-383 ng/L) ( P = .66). MACE were observed in 6 patients (3.1%) in the metformin group and in 2 patients (1.1%) in the placebo group ( P = .16). Creatinine concentration (79 µmol/L [IQR, 70-87 µmol/L] vs 79 µmol/L [IQR, 72-89 µmol/L], P = .61) and glycated hemoglobin (5.9% [IQR, 5.6%-6.1%] vs 5.9% [IQR, 5.7%-6.1%], P = .15) were not significantly different between both groups. No cases of lactic acidosis were observed. Conclusions and Relevance Among patients without diabetes presenting with STEMI and undergoing primary PCI, the use of metformin compared with placebo did not result in improved LVEF after 4 months. The present findings do not support the use of metformin in this setting. Trial Registration clinicaltrials.gov Identifier:NCT01217307.

Background Aromatase inhibitors (AIs) frequently lead to the AI-induced musculoskeletal syndrome (AIMSS). Looking into its pathophysiology, 6 months of AI therapy thickens the tendon sheath with intra-articular fluid (IAF) retention and loss of grip strength. We here report 24-month follow-up data. Patients and methods A prospective cohort study of 33 postmenopausal breast cancer patients received adjuvant endocrine therapy; 27 received an AI and 6 received tamoxifen. At baseline, 6 and 24 months patients had a rheumatologic examination, including a grip strength test, and magnetic resonance imaging of both hands and wrists. The primary end point was tenosynovial changes; secondary end points were changes in morning stiffness, grip strength and IAF. Results Twenty-three AI and 5 tamoxifen patients completed all investigations. Between month 6 and 24, IAF further increased in AI users (P = 0.04) but not in tamoxifen users, and grip strength further decreased in both groups. The worsened tenosynovial changes were strongly correlated with a decrease in grip strength. At 24 months, morning stiffness continued to be present in over a third of AI users. Conclusion AIMSS represents a substantial problem in breast cancer patients. It is associated with tenosynovial changes, IAF retention, joint stiffness and loss of grip strength that do not improve with prolonged use.

Several surgical techniques to treat thumb basal joint arthritis have been described. In this study we compared the results of a cemented thumb basal joint with trapeziectomy with a ligament reconstruction and tendon interposition. A questionnaire was sent to all 519 patients, 322 (with 382 procedures) responded. No significant differences were found when comparing impairment, pain, patient satisfaction and disability. Given the fact that the superiority of a prosthesis cannot be proven and the cost of the implant is greater, we recommend the trapeziectomy with ligament reconstruction and tendon interposition as opposed to arthroplasty as the first choice in the treatment of basal joint osteoarthritis of the thumb.

The outcome of a metaphyseal ulnar shortening osteotomy, reported by Sennwald as an alternative option for ulnar abutment syndrome, was evaluated with -regard to the functional results, pain relief and incidence of complications.We conducted a review of 12 patients ; measured parameters were DASH score, PRWE, VAS for pain, grip force and wrist motion.Only disability improved significantly with a DASH score of 42 (p = 0.03). The function and pain assessment scores did not improve in 3 patients. We found no correlation between change in functional scores and other measured variables. Six patients were reoperated for prominent screw heads or new-onset distal radioulnar joint osteoarthritis.All osteomies healed fast and uneventfully and disability improved in most patients but 25% did not improve and 50% were re-operated. Further investigation is needed to evaluate the value of the metaphyseal osteotomy as an alternative treatment for ulnar abutment syndrome.

Aims: The aim of this study was to evaluate clinical outcome for different indications for PCI in an unselected, nationwide PCI population at short- and long-term follow-up.Methods and results: We evaluated clinical outcome up to six years after PCI in all patients undergoing a PCI procedure for different indications in Sweden between 2006 and 2010. A total of 70,479 patients were treated for stable coronary artery disease (CAD) (21.0%), unstable angina (11.0%), non-ST-elevation myocardial infarction (NSTEMI) (36.6%) and ST-elevation myocardial infarction (STEMI) (31.4%). Mortality was higher in STEMI patients at one year after PCI (9.6%) compared to NSTEMI (4.7%), unstable angina (2.2%) and stable CAD (2.0%). At one year after PCI until the end of follow-up, the adjusted mortality risk (one to six years after PCI) and the risk of myocardial infarction were comparable between NSTEMI and STEMI patients and lower in patients with unstable angina and stable CAD. The adjusted risk of stent thrombosis and heart failure was highest in STEMI patients.Conclusions: The risk of short-term mortality, heart failure and stent thrombosis is highest for STEMI patients after PCI. Therapies to reduce stent thrombosis and heart failure appear to be most important in decreasing mortality in patients with STEMI or NSTEMI undergoing PCI.

Cigarette smokers with ST-segment elevation myocardial infarction (STEMI) may present different response to potent antithrombotic therapy compared to nonsmokers. We assessed the impact of smoking status and intracoronary abciximab in patients with STEMI undergoing primary percutaneous coronary intervention (PCI). We pooled data from 5 randomized trials comparing intracoronary versus intravenous abciximab bolus in patients undergoing primary PCI. The primary end point was the composite of death or reinfarction at a mean follow-up of 292 ± 138 days. Of 3,158 participants, 1,369 (43.3%) were smokers, and they had a lower risk of the primary end point in crude, but not in adjusted analyses (hazard ratio [HR] 0.87, 95% confidence interval [CI] 0.63 to 1.21, p = 0.405). Intracoronary versus intravenous abciximab was associated with a significant reduction in the risk of primary end point among smokers (3.6% vs 8.0%; HR 0.43, 95% CI 0.26 to 0.72, p = 0.001), but not in nonsmokers (10.2% vs 9.9%; HR 0.99, 95% CI 0.72 to 1.36, p = 0.96), with a significant interaction (p = 0.009). Furthermore, intracoronary abciximab decreased the risk of reinfarction in smokers (HR 0.30, 95% CI 0.15 to 0.62, p = 0.001), with no difference in nonsmokers (HR 1.20, 95% CI 0.71 to 2.01, p = 0.50). Stent thrombosis was lowered by intracoronary abciximab in smokers (HR 0.28, 95% CI 0.06 to 0.66, p = 0.009), but was ineffective in nonsmokers (HR 1.04, 95% CI 0.54 to 2.00, p = 0.903). Interaction testing showed heterogeneity in treatment effect for reinfarction (p = 0.002) and stent thrombosis (p = 0.018) according to smoking status. In conclusion, among patients with STEMI undergoing primary PCI, smoking status did not affect the adjusted risk of clinical events. Intracoronary abciximab bolus improved clinical outcomes by reducing the risk of death or reinfarction. Sin financiación 3.398 JCR (2016) Q2, 47/126 Cardiac & Cardiovascular Systems UEC

Background Our preliminary results showed that tenosynovial changes and decrease in grip strength are associated with the aromatase inhibitor-induced musculoskeletal syndrome (AIMSS). Here, we report the final results and assess the relationship between grip strength and body mass index (BMI). Patients and methods We conducted a prospective study including postmenopausal early breast cancer patients receiving either an aromatase inhibitor (AI) or tamoxifen. Primary end point was change from baseline in tenosynovial abnormalities. Secondary end points were changes from baseline in morning stiffness, intra-articular fluid and grip strength and its association with BMI. Results After 6 months of therapy, 74% [95% confidence interval (CI) 51% to 89%] of AI-treated patients had worsened tenosynovial abnormalities, 56% (95% CI 34% to 75%) had increased intra-articular fluid, and 22% (95% CI 9% to 45%) had increased morning stiffness. Grip strength decreased 8% for the left hand (95% CI 2% to 21%) and 11% for the right (95% CI 4% to 17%). Regression analysis suggested that grip strength decreased more for subjects with high or with low BMI. Conclusions AIMSS is characterized by tenosynovial changes, intra-articular fluid and morning stiffness. We hypothesize that the quadratic association between BMI and loss of grip strength reflects AI-induced changes on the endocrine control of the growth hormone insulin-like growth factor-I pathway.

In the Outerbridge-Kashiwagi ulnohumeral arthroplasty, bone strength may be weakened significantly as a result of the humeral fenestration. Therefore, fracture risks may be increased, particularly in the immediate postoperative period. The objective of this biomechanical cadaver study is to study the humeral bone strength after ulnohumeral arthroplasty. A biomechanical cadaveric study was done in which differences in force needed to fracture the humerus with and without fenestration was measured. First, the diaphysis of 12 distal humeri was embedded and a posterior force was applied until a fracture occurred. Second, a similar study was done with fixed humeral columns, to specifically compare the column strength. In the first part, the force needed to fracture was reduced by 17% after ulnohumeral arthroplasty, which was not statistically significant. However, a shift in the fracture pattern occurred: from diaphyseal fracture towards column fractures after the arthroplasty. In the second part, the force needed to fracture the columns proved to be significantly reduced by 41% after humeral perforation. Alterations in the biomechanical properties of the distal humerus after ulnohumeral arthroplasty may lead to a shift in fracture patterns from diaphyseal to column fractures. The strength of the columns is strongly reduced by 41%.

Aims: Primary percutaneous coronary intervention (PCI) is a widely practised therapeutic procedure to treat ST-elevation myocardial infarction (STEM l). However, a significant proportion of patients undergoing primary PCI suffers from adverse events, such as incomplete myocardial reperfusion. It is currently unknown to which degree these adverse events are operator related. Methods and results: We investigated inter-operator variation using objective safety and efficacy endpoints during primary PCI for STEM I. All PCIs were performed by six experienced interventional cardiologists as part of a randomised single centre trial. The primary endpoint of this study was optimal myocardial reperfusion (myocardial blush grade 3 [MBG]). All 1,071 patients enrolled in the Thrombus Aspiration during Percutaneous coronary intervention in Acute myocardial infarction Study (TAPAS) were included in this analysis. In the six operator groups, the rate of the primary endpoint MBG 3 ranged between 29.2% and 55.5%. The variable for operators remained significantly associated with MBG 3 after adjustment for baseline and procedural differences. There were no statistical differences observed with regard to safety endpoints. Conclusions: This study illustrates the observation that even in a controlled setting significant inter-operator variation may exist in the efficacy of primary PCI. This study supports the routine collection of high-quality datasets to evaluate and improve individual operator competence and skills.

Dupuytren's disease (DD) can lead to severe disabling finger contractures resistant to surgical treatment. In some cases, finger or ray amputation is considered, due to a severe functional deficit or vascular injury. To evaluate the weight of amputation surgery in DD, a retrospective study was conducted over a 5-year time interval, outlining all indications for elective finger amputation and its prevalence in the total of surgical interventions for DD. The outcome in DD was compared to post-traumatic amputations. Out of 31 elective finger and ray amputations, 12 (39%) were indicated for DD, all in the 4th or 5th ray, of which 92% were in recurrent disease. In the 646 surgical procedures for DD in the matching time interval, we conclude that almost 2% were elective amputations. The outcome of amputation in DD was similar to post-traumatic amputations. Based on these data, we feel that patients should be informed that sometimes, surgical treatment for Dupuytren's disease can lead to an eventual decision to amputate.

A cross sectional study where 145 hairdressers were interviewed for the occurrence of work related upper limb disorders (WRULD). The interview features for engagement, burnout and workaholism, as well as asks for general health and working conditions. The BMI, the hand size and gripping force of each worker was obtained. WRULD was present in 41%. It was significantly correlated with burnout and workaholism. Surprisingly it was not altered by engagement or by the use of ergonomic equipment. Morphological features (BMI), hand size and gripping force, were not related to the occurrence of WRULD.

Objectives: To investigate the feasibility and safety of manual thrombus aspiration in patients undergoing percutaneous coronary intervention (PCI) for non-ST-elevation myocardial infarction (NSTEMI). Background: Myocardial necrosis in patients with acute coronary syndromes may be a sign of microvascular obstruction, owing to spontaneous or PCI-induced embolization of atherothrombotic material. Manual thrombus aspiration results in improved myocardial reperfusion in patients undergoing PCI for ST-elevation myocardial infarction. Currently, no published data on thrombus aspiration in patients with NSTEMI are available. Methods: As part of a prospective cohort study, 70 patients undergoing PCI for NSTEMI were treated with thrombus aspiration (Export Aspiration Catheter, Medtronic, Minneapolis, MN). Histopathological analysis was performed on aspirated material. Results: Thrombus aspiration was effective in 58 patients (83%) and resulted in a marked reduction of TIMI-thrombus score 4/5 (40% pre-versus 7% postthrombus aspiration) and increase of the rate of TIMI-flow 3 (36% pre-versus 66% postthrombus aspiration). The incidence of myocardial blush grade 2 and 3 were 39 and 45%, respectively. Distal embolization was visible in three patients (4%) on the final angiogram. Conclusion: This study demonstrates that thrombus aspiration in most NSTEMI patients is feasible and safe and is associated with a high rate of retrieval of thrombotic material.

Aims To evaluate non-invasive angiography using dual-source computed tomography (CT) for the determination of the most appropriate therapeutic strategy in patients with suspected coronary artery disease (CAD). Methods and results CT angiography (Dual Source CT, Somatom Definition, Siemens Medical Systems, Forchheim, Germany) was performed in 60 consecutive patients [51 men, median age 64 (57–70) years] scheduled for elective coronary angiography. Both techniques were used to evaluate the presence of CAD, significant stenosis, and the need for revascularization therapy. Sensitivity and specificity for the presence of significant stenosis were: per segment ( n = 766) 62% (95% CI 50–72) (64/104) and 79% (95% CI 74–84) (526/662), respectively; per patient ( n = 60) 100% (95% CI 91–100) (38/38) and 45% (95% CI 24–68) (10/22), respectively. In therapeutic decision-making based on CT angiography, sensitivity, specificity, positive and negative predictive values for intervention were 97% (95% CI 84–100) (36/37), 48% (95% CI 27–69) (11/23), 75% (95% CI 60–86) (36/48), and 92% (95% CI 60–100) (11/12), respectively. If a revascularization procedure was needed, the CT angiographic data indicated the appropriate modality (percutaneous coronary intervention or coronary artery bypass grafting) in 70% (26/36) of patients. Conclusion Although imaging qualities have improved considerably, CT angiography cannot be used for definitive therapeutic decision-making with regard to revascularization procedures in patients with suspected CAD.

Background Controversy exists regarding the factors influencing the duration of work incapacity after surgically treated carpal tunnel syndrome (CTS). Aim To determine relevant factors related to return to work. Methods Surgical technique, clinical factors, demographic factors, other medical problems, psychosocial factors, work-related and economical factors were reviewed in patients operated on for CTS. Statistical multivariate analyses were performed to identify the baseline factors influencing the work incapacity period. Results A total of 107 cases were reviewed. Professional exposure to repetitive movements and heavy manual handling activity were associated with a longer return-to-work interval. The duration of work incapacity period was not significantly related to the socioprofessional category of the patient (self-employed or employee) or to the type of the procedure (open versus endoscopic surgery). Conclusion Work-related features have a more important influence on return to work than personal, pathological or surgical features.

We report three cases of mycobacterium marinum infection, characterized by the long duration before a proper diagnosis was made. Mycobacterium marinum is a so-called atypical non-tuberculous mycobacterium, found in salt and fresh water, occasionally infecting humans. Most of the infections involve the fingers and hand, after exposure to contaminated water. It is commonly called fish tank infection. The clinical pictures can be very different: from a small cutaneous lesion to deep-seated infections of the tendon sheet or joint. Special transport and culture techniques are required for proper diagnosis. Besides surgical treatment of chronic skin lesions and deep infections, prolonged treatment with appropriate antibiotics is required.

We report on a unique case of a young female patient with the Goltz-Gorlin syndrome who developed a giant cell tumor of bone in the distal phalanx of the thumb. This case is noteworthy because of the combination of some unusual features. Firstly, it is only the fifth case report on the association of giant cell tumor of bone and the Goltz-Gorlin syndrome. Also the localization of the lesion in the bones of the hand and the presentation at adolescent age is rarely seen.

To evaluate the results of open reduction and ulnar osteotomy on missed Monteggia fractures in children.Retrospective review.Tertiary care center orthopaedic hospital in Pellenberg, Belgium.Six children between 2 and 6 years old who sustained a Monteggia fracture that was initially missed were treated at our institute. They presented in our hospital 5 to 59 weeks postinjury.Open reduction of the radial head was performed, combined with a dorsal opening wedge osteotomy of the proximal ulna and fixation with plate and screws.Mobility of the elbow was measured by an independent observer, evaluating flexion-extension and pronation-supination preoperatively and postoperatively.All patients regained a normal range of motion, the radial head remained relocated, and the axis of the forearm remained normal.This operation-open reduction of the radial head and osteotomy of the ulna-results in an excellent outcome for a missed Monteggia fracture in children.

Greig cephalopolysyndactyly (GCPS) (OMIM 175700) is an autosomal dominant disorder characterized by a distinct combination of craniofacial, hand and foot malformations. In this report, clinical and radiological findings of 12 patients with GCPS derived from 4 independent families and 3 sporadic cases with documented GLI3 mutations are presented with particular emphasis on inter- and intrafamilial variability. In a particularly instructive family in which 9 members of 4 generations could be studied clinically and molecularly, a missense mutation (R625W) is transmitted and shows a partially penetrant pattern. In a branch of the family, the GCPS phenotype skips a generation via a normal female carrier without clinical signs providing evidence that GCPS does not always manifest full penetrance as generally supposed. © 2003 Wiley-Liss, Inc.

Introduction: Trapeziometacarpal pre-arthrosis is a common condition with only limited therapeutic possibilities. Eaton and Littler designed a tendon stabilization. Materials and methods: A series of 21 thumbs with painful carpometacarpal joints, treated with a ligament reconstruction according to Eaton and Littler, is described. Three failed and further surgery was required. The outcome of 18 is evaluated. There were 11 women, 7 men with a mean age of 33.7 years, all having stages I or II of osteoarthritis. Six (30%) had a traumatic event in their history. Results: In the early stages of degenerative osteoarthritis, the overall outcome was good with a mean DASH score of 23.2. The carpometacarpal joint was stable but a 43% progression of radiographic osteoarthritic deterioration of the joint occurred. Conclusion: Stabilization of a painful pre-arthritic trapeziometacarpal joint is useful and reliable. A traumatic instability had worse results and probably is a contraindication to this technique.

We reviewed 14 patients treated with either an ulnar or a hypothenar fat flap for recurrent carpal tunnel syndrome and scar tenderness. Nine patients were satisfied and there were few complications. One patient had delayed skin healing and another developed a hypertrophic scar.

Focal fibrocartilaginous dysplasia (FFCD) is an uncommon, benign bone lesion that causes angular deformities of the long bones in young children. Most deformities were seen around the knee. Diagnostic criteria are based on clinical and radiological signs: unilateral angular deformity in a long bone of a young child, associated with on X-ray a typical lucent bony defect with surrounding sclerosis at the concavity of the deformity with a cortical defect. The etiology is not understood. There were 16 cases described previously involving the upper extremity: 9 cases with FFCD of the ulna, 3 of the humerus, 2 of the radius and 2 of the phalanx. We report a case of cubitus varus deformity in a young girl of 2 years and 2 months where the deformity worsened very quickly. We believe that debridement of the fibrous tether at very young age will prevent further deformity and can correct spontaneously by remaining growth.

Aims: In recent years, intracoronary bolus abciximab has emerged as an alternative to the standard intravenous route in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). The aim of the current study was to perform an individual patient-level pooled analysis of randomised trials, comparing intracoronary versus intravenous abciximab bolus use in STEMI patients undergoing primary PCI. Methods and results: Individual data of 3,158 patients enrolled in five trials were analysed. Reperfusion endpoints were: post-procedural Thrombolysis in Myocardial Infarction (TIMI) 3 flow, myocardial blush grade (MBG) 2/3 and complete ST-segment resolution. The primary clinical endpoint of interest was the composite of death and reinfarction at 30 days. Compared with the intravenous route, intracoronary abciximab bolus administration did not improve TIMI 3 flow (odds ratio [OR] 1.19; 95% confidence interval [CI]: 0.90-1.59; p=0.23) and complete ST-segment resolution (OR 1.22, 95% CI: 0.92-1.63, p=0.17), but increased MBG 2/3 occurrence (OR 1.83, 95% CI: 1.05-3.18, p=0.03). At 30-day follow-up, intracoronary bolus abciximab did not reduce the risk of death and reinfarction (OR 0.78, 95% CI: 0.55-1.10, p=0.16), death (OR 0.77, 95% CI: 0.51-1.17, p=0.22), reinfarction (OR 0.79, 95% CI: 0.46-1.33, p=0.38) and stent thrombosis (OR 0.77, 95% CI: 0.43-1.35, p=0.36) as compared with intravenous administration. Conclusions: In STEMI patients undergoing primary PCI, intracoronary abciximab does not provide additional benefits as compared with standard intravenous treatment and, therefore, it should not be recommended as the default route of administration in this setting.

Bizarre parosteal osteochondromatous proliferation is a rare tumor usually localized in the hand. We report two new cases, one in the thumb of a middle aged woman and one in the terminal phalanx of a young haemophiliac patient.

Previously published reports have shown good results after proximal row carpectomy in all cases that had a postoperative immobilisation period from 1 to 4 weeks. Immobilisation is thought to be necessary because of the risk of postoperative subluxation of the carpus and for pain relief. There is, however, no evidence of its value. The results in 13 patients who underwent proximal row carpectomy without postoperative immobilisation were compared with those in 25 patients who underwent proximal row carpectomy with postoperative immobilisation for 4 weeks. After a mean follow-up period of 27 months, no significant differences were found for pain, range of motion or return to work between the two groups. We conclude that postoperative immobilisation is not necessary after proximal row carpectomy.

The clinical and radiologic spectrum of symbrachydactyly has been extended, on the basis of experimental embryology, into four categories: typical symbrachydactyly, atypical cleft hand, monodactyly, and adactyly. The origin of this embryologic failure is probably a vascular disruption. A series of 64 hands and 3 feet are reported, indicating associated anomalies and possible etiologic features.

The results of open subacromial decompression (OSD) were compared with arthroscopic subacromial decompression (ASD) after 1 year in 32 subjects (4 bilateral), and the correlation between the two shoulder rating scales for impingement was documented. Patients were evaluated clinically on the modified University of California at Los Angeles (UCLA) shoulder rating scale, and Constant scale. Scapular position and rotation were evaluated as well as a rotation and abduction shoulder strength test using the Cybex II dynamometer. No parameters revealed significant differences between the groups, except for the UCLA score which indicated an advantage for the ASD group (p=0.046). The OSD group scored 24.5 (5.45) on the UCLA scale and 73.8 (18.9) on the Constant scale, whereas the ASD group scored 28.3 (5.6) and 80.8 (16.4). To study the correlation between both scales, the Pearson correlation product-moment coefficient was calculated and a high correlation (r=0.81) obtained. Less mobility was found in the operated arm for all parameters, with the exception of glenohumeral abduction in both groups and passive elevation in the OSD group. Only in the OSD group did the scapula in the operated extremity show more abduction of the inferior angle of the scapula. Weaker abduction strength in the operated side was found in the ASD group, whereas in the OSD group there was significantly less adduction and external rotation strength at 180°/s en 240°/s. We conclude that after one year the open group tends to catch up with the arthroscopic patients and that the main benefits after arthroscopic surgery as described in literature are more evident in the shorter period.

This is a review of 20 patients (22 operations) with symptomatic osteoarthritis of the first carpometacarpal joint who were treated by simple trapezectomy without interposition material. They were all women with a mean age of 60 years (46-77). The average follow-up was 2 years, ranging from 8 months to 3 years. Pain relief is the main contributor to the good clinical results of this procedure. Sixteen patients professed to be very satisfied, two had a fair result and four cases claimed to be unsatisfied. Range of motion (opposition and counter opposition) and first web space were very well preserved. Mean values of grip strength showed reduction of grip power on the operated side though not statistically. However, we did find a statistically significant difference in pinch strength between operated and non-operated side. In general, simple trapezectomy is our preferred surgical therapy in the treatment of carpometacarpal osteoarthritis in the elderly population.

Introduction. - Dans le traitement chirurgical des rhizarthroses, plusieurs solutions sont possibles. L'arthrodese devrait mener a une articulation stable, indolore et une amelioration de la force. Certains auteurs, neanmoins ont publie des resultats mediocres. Materiel et methodes. - Dans une revue retrospective nous avons examine 34 patients (26 hommes, 8 femmes) ayant subi une arthrodese trapezometacarpienne. L'age moyen etait de 48 ans. Deux types de fixation ont ete employees: agrafes (16x) ou broches (18x). Le suivi moyen etait de 5,2 ans. Resultats. - Un taux de 39 % de pseudarthroses a ete observe. 60 % des patients seulement ont ete satisfaits. Le DASH score etait de 32 (deviation standard 18). Une reduction de la mobilite des l'articulations interphalangiennes (6°) et metacarpophalangiennes (27°) a ete observee. La force etait reduite de 27 %. Dans les cas consolides, la satisfaction du patient etait de 88 %. Conclusion. - La satisfaction des patients etait moderee et le taux de pseudarthrose important. Les resultats etaient nettement meilleurs dans les cas ou la consolidation a ete obtenue. Des fixations plus solides, et un apport de greffons osseux peuvent ameliorer les resultats cliniques.

Avascular necrosis of the capitate is rare. Little is known about the aetiology, disease progression or optimal management. From 1992 to 2012 we treated six patients; four had a scaphocapitolunate arthrodesis and two had a four corner arthrodesis. The average follow up was 9 years (range 1–20). Three patients had good or excellent results, two fair and one poor, based on a visual analogue scale for pain and satisfaction and a Quick-DASH score. The Mayo wrist score was satisfactory in five cases and poor in one. Better results were seen when the arthrodesis fused. In the English, French and German literature 42 other cases were found. The aetiology, patient characteristics, clinical presentation, treatment and outcome were reviewed. Type of study/level of evidence: therapeutic IV.

Item does not contain fulltext BACKGROUND: If percutaneous coronary intervention (PCI) is required in patients taking oral anticoagulants, antiplatelet therapy with aspirin and clopidogrel is indicated, but such triple therapy increases the risk of serious bleeding. We investigated the safety and efficacy of clopidogrel alone compared with clopidogrel plus aspirin. METHODS: We did an open-label, multicentre, randomised, controlled trial in 15 centres in Belgium and the Netherlands. From November, 2008, to November, 2011, adults receiving oral anticoagulants and undergoing PCI were assigned clopidogrel alone (double therapy) or clopidogrel plus aspirin (triple therapy). The primary outcome was any bleeding episode within 1 year of PCI, assessed by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00769938. FINDINGS: 573 patients were enrolled and 1-year data were available for 279 (98.2%) patients assigned double therapy and 284 (98.3%) assigned triple therapy. Mean ages were 70.3 (SD 7.0) years and 69.5 (8.0) years, respectively. Bleeding episodes were seen in 54 (19.4%) patients receiving double therapy and in 126 (44.4%) receiving triple therapy (hazard ratio [HR] 0.36, 95% CI 0.26-0.50, p

Biodegradable PDS-rods have been used for the treatment of phalangeal neck fractures to oppose the disadvantages and complications of K-wire fixation. Reduction can be maintained during fracture healing, and the surrounding joints can be mobilized early. Because of the recessed position of the rods, there is no interference with motion.

Item does not contain fulltext TLR (Toll-like receptor) activation-induced inflammatory responses are important in the progression of atherosclerosis. We previously showed that TLR-dependent leucocyte responsiveness is acutely attenuated following percutaneous coronary intervention or vascular surgery. Furthermore, cytokine release following whole-blood TLR-2 and TLR-4 stimulation is negatively correlated with fractional flow reserve, suggesting that chronic ischaemia can elicit an enhanced inflammatory response. In the present study, we assessed the association between leucocyte TLR-2 and TLR-4 responsiveness and pre-existent and inducible ischaemia in patients undergoing SPECT (single-photon emission computed tomography)-MPI (myocardial perfusion imaging). TLR-2, TLR-4 and CD11b expression on monocytes were measured in blood samples that were obtained from 100 patients with suspected coronary artery disease before and after myocardial stress testing for SPECT-MPI. IL-8 (interleukin-8) levels were determined after whole-blood stimulation with Pam3Cys (TLR-2) and LPS (lipopolysaccharide; TLR-4). On the basis of SPECT-MPI, patients were categorized into three groups: reversible defect, irreversible defect and no defect. Myocardial stress induced a reduction in TLR-4 expression (2.46+/-0.21 compared with 2.17+/-0.16 arbitrary units, P=0.001) and CD11b expression (83.2+/-1.73 compared with 76.0+/-1.89 arbitrary units, P

Summary Forty-nine patients with chronic wrist pain were examined by radiocarpal arthrography, followed by radiocarpal arthroscopy. One patient had bilateral involvement. None of these patients showed deformities or lesions on standard and dynamic radiographs. Not all patients who underwent arthrography underwent radiocarpal arthroscopy. Sensitivity of arthrography was 52%, specificity 50%, positive predictive value 92%, and negative predictive value 8% compared with arthroscopy. In this patient group, a very low negative predictive value was found: in 92% of the negative arthrographic examinations an arthroscopic lesion was found. Arthrography of the radiocarpal joint is a good examination for confirming a clinical suspected lesion, but is of limited value when negative.

Introduction: Ulnar wrist pain due to a TFCC lesion is frequent. Based on studies of the vascularity, ulnar avulsion can be sutured. Arthroscopic techniques have been designed but results are sparsely published. Materials and methods: This is a retrospective study of 35 patients with an ulnar avulsion of the TFCC. All the patients were treated with an originally designed arthroscopical technique. The evaluation was focused on the subjective and functional ouome. A pain score and a DASH score were used. Results: The general impression was positive with a mean DASH score of 15 points. Two-thirds of the patients had a DASH score totaling less than 20. Twenty-nine patients had a good outcome, six were fair or poor. Conclusion: Arthroscopical repair of the TFCC is a reliable and useful technique.

Objective— Shorter leukocyte telomeres are associated with atherosclerosis and predict future heart disease. The goal of the present study was to determine whether leukocyte telomere length is related to atherosclerotic plaque telomere length and whether it is associated with plaque characteristics or recurrence of disease. Methods and Results— Telomere length was measured by real-time quantitative polymerase chain reaction in atherosclerotic plaques and leukocytes in patients with carotid atherosclerosis undergoing carotid endarterectomy (n=684) and of leukocytes in age- and gender-balanced subjects without clinical atherosclerosis (n=780). Leukocyte telomere length was shorter in patients versus controls (0.99 [interquartile range (IQR): 0.79 to 1.26] versus 1.06 [0.80 to 1.39]; P =0.0007). Plaque telomeres were longer than leukocyte telomeres (1.42 [IQR: 1.21 to 1.77] versus 1.01 [IQR: 0.75 to 1.34]; P −6 ) and independent of age. Leukocyte and plaque telomere length were only weakly correlated (correlation coefficient r 2 =0.04, P =0.03). Patients, whose plaques showed marked macrophage infiltration and large lipid core, had longer plaque telomeres (1.61 [IQR: 1.32 to 2.04] versus 1.40 [IQR: 1.15 to 1.57]; P =0.006) and shorter leukocyte telomeres (0.88 [IQR: 0.75 to 1.20] versus 1.03 [IQR: 0.83 to 1.34]; P =0.02). Plaque telomere length was associated with restenosis 1 year after endarterectomy (OR 1.58±0.206; P =0.026 per SD decrease of plaque telomere length). Conclusion— Leukocyte telomere length is associated with the presence of atherosclerotic carotid plaques but is not a proxy for local plaque telomere length. Plaque telomere length is related to plaque characteristics and development of restenosis following endarterectomy.

Sudden cardiac death (SCD) remains a major health issue accounting for over 5% of annual mortality in the Western world. There are several causes of SCD, most commonly, coronary artery disease. Although identifying the prodrome of SCD has attracted considerable interest, a large proportion of patients die before any medical contact is established. SCD onset seems to follow a circadian pattern, most likely because of exposure to endogenous and exogenous triggers. The aim of the present report is to review the current knowledge of epidemiology, patterns of onset, and triggers of SCD and present directions for future research with a focus on coronary artery disease.

Five cases of symptomatic acquired positive ulnar variance are described. All cases occurred due to premature physeal closure of the growth plate in teenage girl gymnasts. All cases demonstrated ulno-carpal impingement, for which we describe a clinical test. Arthroscopic assessment of the wrist allowed us to assess the integrity of the TFCC (triangular fibrocartilaginous complex) and decide on the most appropriate surgery. Two patients needed distal ulna recession and one needed shaving for a TFCC perforation, with a good result.

This study evaluates if the Disabilites of the Arm, Shoulder and Hand (DASH) questionnaire is an adequately responsive outcome measure in lateral extensor release for tennis elbow. To measure responsiveness (sensitivity to clinical change), 21 patients with operated tennis elbow completed the DASH questionnaire pre-operatively and again postoperatively. The effect size (2.03) and standardized response (1.54) mean that, as well as the correlation with patient satisfaction and the Roles & Maudsley score (10), the DASH questionnaire is a useful tool to evaluate the outcome of surgical treatment of tennis elbow.

A case of lipofibromatous hamartoma of the median nerve with macrodactyly of 2 digits is described. Nerve stripping resulted in a growth control.

Summary Background Percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction can be complicated by spontaneous or angioplasty-induced embolisation of atherothrombotic material. Distal blockage induces microvascular obstruction and can result in less than optimum reperfusion of viable myocardium. The Thrombus Aspiration during Percutaneous coronary intervention in Acute myocardial infarction Study (TAPAS) found that thrombus aspiration resulted in improved myocardial reperfusion compared with conventional PCI, but whether this benefit improves clinical outcome is unknown. We aimed to investigate whether the early efficacy of thrombus aspiration seen in TAPAS translated into clinical benefit after 1 year. Methods Patients with ST-elevation myocardial infarction enrolled at the University Medical Centre Groningen were randomly assigned in a 1:1 ratio to either thrombus aspiration or conventional treatment, before undergoing initial coronary angiography. Exclusion criteria were rescue PCI after thrombolysis and known existence of a concomitant disease with life expectancy less than 6 months. Of the 1071 patients enrolled between January, 2005, and December, 2006, vital status at or beyond 1 year after randomisation was available for 1060 (99%). The primary endpoint was cardiac death or non-fatal reinfarction after 1 year, and analysis was by intention to treat. The TAPAS trial is registered with Current Controlled Trials number ISRCTN16716833. Findings Cardiac death at 1 year was 3·6% (19 of 535 patients) in the thrombus aspiration group and 6·7% (36 of 536) in the conventional PCI group (hazard ratio [HR] 1·93; 95% CI 1·11–3·37; p=0·020). 1-year cardiac death or non-fatal reinfarction occurred in 5·6% (30 of 535) of patients in the thrombus aspiration group and 9·9% (53 of 536) of patients in the conventional PCI group (HR 1·81; 95% CI 1·16–2·84; p=0·009). Interpretation Compared with conventional PCI, thrombus aspiration before stenting of the infarcted artery seems to improve the 1-year clinical outcome after PCI for ST-elevation myocardial infarction.

Objectives: To compare Angio-Seal (AS) and StarClose (SC) and manual compression (MC) on efficacy of hemostasis, complication rate, safety of early mobilization, and patient comfort. Background: Closure of the femoral artery after cardiac catheterization can be obtained through different methods. Today, physicians can choose from a number of different devices to achieve arterial closure. Methods: In a prospective trial 450 patients were randomized to AS, SC, or MC. Patients were mobilized 1 to 2 hr after device placement, and 6 hr after MC. Data were collected during hospital admission and by telephone at one month after hospital discharge. Results: Devices were used in 138/150 allocated to AS and 124/150 allocated to SC patients (92% vs. 83%, P = 0.015) Patients with MC experienced more pain during sheath removal than patients receiving a device, and rated their period of bed rest as less comfortable. Oozing and need for pressure bandage at the puncture site were observed in 37 AS patients and 57 SC patients (25% vs. 38%, P = 0.002). Hematoma occurred in 15 AS patients, in 17 SC patients, and in 14 MC patients (11 vs. 14 vs. 9%, Ins). Conclusion: There is no difference in safety between the three methods of arterial closure. SC was more often not used or successfully deployed. SC patients more often had continuing oozing. On patient comfort, closure devices performed better than MC. Early ambulation in patients with a closure device is safe. AS is the preferred method of arterial closure after cardiac catheterization. (C) 2008 Wiley-Liss, Inc.

Background Primary percutaneous coronary intervention (PCI) is effective in opening the infarctrelated artery in patients with myocardial infarction with ST-segment elevation. However, the embolization of atherothrombotic debris induces microvascular obstruction and diminishes myocardial reperfusion. Methods We performed a randomized trial assessing whether manual aspiration was superior to conventional treatment during primary PCI. A total of 1071 patients were randomly assigned to the thrombus-aspiration group or the conventional-PCI group before undergoing coronary angiography. Aspiration was considered to be successful if there was histopathological evidence of atherothrombotic material. We assessed angiographic and electrocardiographic signs of myocardial reperfusion, as well as clinical outcome. The primary end point was a myocardial blush grade of 0 or 1 (defined as absent or minimal myocardial reperfusion, respectively). Results A myocardial blush grade of 0 or 1 occurred in 17.1% of the patients in the thrombus-aspiration group and in 26.3% of those in the conventional-PCI group (P
