Incidental findings in multislice computed tomography prior to transcatheter aortic valve implantation: frequency,clinical relevance and outcome

Multislice computed tomography (MSCT) has emerged as the mainstay in patients planned for transcatheter aortic valve implantation (TAVI). Incidental findings (IF) in MSCT are common. However, the exact incidence, clinical relevance and further consequences of IF are unclear and it is controversial whether IF adversely affect patients’ outcome. We analyzed MSCT data of 1050 patients screened for TAVI between January 2011 and December 2014. Median follow-up of patients was 20 months. In total, 3194 IF were identified, which were classified into clinically non-relevant IF (2872, 90%) and clinically relevant IF (322, 10%). In 25% of patients (258/1050) at least one clinically relevant IF was present. Age (80?±?7 vs. 80?±?7 years; p?=?0.198) and EuroSCORE II (3.6% [2.1–5.7] vs. 3.6% [2.1–5.9]; p?=?0.874) was similar between patients with and without a clinically relevant IF. TAVI was performed less frequently in patients with a clinically relevant IF (76% vs. 85%; p?<?0.001), with more patients receiving surgical aortic valve replacement in that group (14% vs. 11%; p?=?0.042), possibly due to the high rate of incidental aneurysms of the ascending aorta (n?=?48). If TAVI was performed mortality did not differ (30-days: 4% vs. 3%; p?=?0.339, 1-year: 11% vs. 14%; p?=?0.226) between patients with and without a clinically relevant IF. Our study is the largest study to analyze prevalence, clinical relevance and therapeutic consequences of IF during screening for TAVI. IF in pre-procedural MSCT are common and clinically relevant in one-quarter of patients. However, these findings had no impact on overall mortality.     

Inhibition of interleukin-8 synthesis by intraarticular methotrexate therapy in patientes with rheumatoid arthritis

Summary 5 Patients with definite RA and knee effusions under constant doses of DMARD therapy were treated with up to 6 intraarticular injections of 10mg methotrexate (MTX) every 3 to 7 days. A matched randomized control group who received a single i.a. injection of 40mg triamcinolone hexacetonide (TC) was monitored according to the same protocol. The intraarticular granulocyte counts and IL-8 levels decreased in all MTX treated patients on day 10–13 and stayed low in those patients who could be re-evaluated after 13 weeks. Compared to the IL-8 levels, the other tested cytokine levels showed only minor changes on day 10–13. There was no need for re-injection in the TC group during the 13 week study phase. We conclude that intraarticular MTX therapy results in a strong decrease of SF-granulocyte counts. This effect may be due to the impairment of IL-8 mediated chemotaxis by decreased IL-8 synthesis in synovial fluid mononuclear cells. Clinically, repeated intraarticular MTX therapy results in a worse 13 week outcome than i.a. steroid treatment measured in an intention-to-treat analysis. Eingegangen: 14. April 1997 Akzeptiert: 15.

Adolescents’ somatic complaints in eight countries: what influence do parental rearing styles have?

Medically unexplained physical symptoms are frequently named by adolescents in both clinical and normative samples. This study analyzed the associations between parental rearing styles and adolescents’ body complaints in diverse cultural contexts. In a cross-cultural study of 2415 adolescents from eight countries (Argentina, France, Germany, Greece, Pakistan, Peru, Poland, and Turkey), the associations of maternal and paternal support, psychological control, and an anxious parental monitoring style with youth body complaints were tested. Girls reported more somatic complaints than boys, the level of complaints differed between countries, and gender differences varied significantly between countries. Hierarchic multilevel models revealed that the expression of distress via body complaints, after controlling for country, gender, and sociodemographic status, was significantly associated with parental rearing styles. The negative impact of mothers’ psychological control on body complaints generalize across countries. In addition, mothers’ anxious monitoring had a negative impact on the offspring’s health, whereas higher levels of paternal support and lower levels of paternal psychological control contributed to lower levels of somatic complaints. Sociodemographic variables such as family structure, standard of living, and employment status of the parents, did not turn out as significant in the final model. The findings point to the different roles of fathers and mothers play in adolescents’ health and their complex interplay.

     

Comparison of latest generation supra-annular and intra-annular self-expanding transcatheter heart valves

BackgroundThis study compares two latest-generation self-expanding transcatheter heart valves (THV), the supra-annular ACURATE neo (Boston Scientific) and the intra-annular Centera THV (Edwards Lifesciences).MethodsIn this single center observational cohort trial 317 patients treated with the ACURATE neo and 78 patients treated with the Centera TVH were included. The main endpoints were device success and the early safety endpoint at 30 days.ResultsBesides higher incidence of diabetes mellitus and higher body mass index in patients treated with the ACURATE neo THV, there were no baseline differences between the groups. Device success was similar in both groups (neo: 91.8% vs. Centera: 93.6%; P=0.598), with numerically higher rates of moderate to severe paravalvular leakage in the ACURATE neo group (4.7% vs. 1.3%; P=0.214). At 30 days all-cause mortality rates were low in both groups (0.3% vs. 0%; P=0.620) and no difference occurred in the early safety at 30 days (19.3% vs. 16.7%; P=0.599). However, all-cause stroke rates were significantly higher in patients treated with the Centera THV (6.4 vs. 1.6%; P=0.015).ConclusionsThe ACURATE neo and the Centera THV show low mortality rates as well as comparable, favorable hemodynamics. The finding of higher stroke rates at 30 days with the repositionable Centera SE-THV needs further assessment.     

IDIOPATHIC ISOLATED BILATERALLY SYMMETRICAL BRACHYMETACARPIA OF THE FIFTH METACARPAL: Case report

We report a rare case of a 32-year-old woman with idiopathic isolated bilaterally symmetrical brachymetacarpia of the fifth metacarpal bone, which had been present since the age of 14. Movement, and sensory and motor function were within normal limits, and she had no symptoms. No treatment was recommended. We know of no similar case reports.     

Pocket hematoma after pacemaker or implantable cardioverter defibrillator surgery: influence of patient morbidity, operation strategy, and perioperative antiplatelet/anticoagulation therapy

STUDY OBJECTIVES: Pocket hematoma is a common complication after pacemaker or implantable cardioverter defibrillator (ICD) implantation. Thus, we investigated the influence of patient comorbidity, implantation strategy, operator experience, antiplatelet therapy, and anticoagulation therapy on hematoma rate. DESIGN: Between 1990 and 2002, a total of 3,164 devices (pectoral pacemakers, 2,792; ICDs, 372) were implanted at our institution. Predictors of hematoma occurrence were determined prospectively and were analyzed by multivariate regression analysis. Operator experience was graded by individual implantation number, as follows: low, < 50; medium, 50 to 100; and high, > 100. RESULTS: The incidence of pocket hematoma was 4.9%, leading to prolonged hospitalization in 2.0% of all patients. Reoperation for pocket hematoma was required in 1.0% of patients. High-dose heparinization (hazard ratio [HR], 4.2), combined acetylsalicylic acid (ASA)/thienopyridine treatment after coronary stenting (HR, 5.2), and low operator experience (HR, 1.6) were independently predictive of hematoma development. Therapy with ASA alone did not increase the hematoma rate compared to patients who did receive antiplatelet or anticoagulation therapy (3.1% vs 2.5%, respectively; difference not significant). In patients with nonvalvular atrial fibrillation, postoperative high-dose heparinization substantially increased the hematoma rate (10.7% vs 2.9%, respectively; p < 0.001) without reducing the rate of arterial embolism within the first month after implantation (0.18% vs 0.21%, respectively; difference not significant). The infection rate (0.28% within 3 months after implantation) was not influenced by the presence of the pocket hematoma. CONCLUSIONS: The use of high-dose heparinization and combined ASA/thienopyridine treatment are highly predictive for the occurrence of intraoperative bleeding and pocket hematoma in patients who have undergone pacemaker and ICD surgery. We propose recommendations for the management of antiplatelet and anticoagulation therapy in patients undergoing these interventions.     

Evolución de pacientes tratados con armazones coronarios bioabsorbibles liberadores de everolimus tras su disolución completa

Introduction and objectivesLong-term outcomes of unselected patients treated with bioresorbable vascular scaffold (BVS) implantation are lacking, especially for the period after complete dissolution of the BVS. This study sought to evaluate 5-year outcomes in patients treated with BVS in routine practice.MethodsConsecutive patients who underwent implantation of everolimus-eluting BVS during routine clinical practice at 2 high-volume centres in Germany were studied. The patients were followed-up for up to 5 years. The primary endpoints of interest were the composite of death, myocardial infarction and target lesion revascularization, as well as definite scaffold thrombosis.ResultsA total of 419 patients (mean age 66.6 ± 10.9 years; 31.5% had diabetes) were included, of whom 38.9% presented with an acute coronary syndrome. Of the 527 lesions treated, 49.0% were classified as complex and 13.1% were bifurcation lesions. At 5 years, the composite clinical endpoint occurred in 33.1% of patients and definite scaffold thrombosis occurred in 4.7%. Most definite scaffold thrombosis occurred within 2 years after BVS implantation.ConclusionsIn patients treated with BVS implantation in routine clinical practice the rates of adverse clinical events at 5 years were high, including a considerable incidence of scaffold thrombosis.
