BACKGROUND Incisional hernia is an important complication of abdominal surgery. Procedures for the repair of these hernias with sutures and with mesh have been reported, but there is no consensus about which type of procedure is best. METHODS Between March 1992 and February 1998, we performed a multicenter trial in which we randomly assigned to suture repair or mesh repair 200 patients who we...
BACKGROUND From 20 to 50% of patients who survive an acute episode of the acquired form of thrombotic thrombocytopenic purpura relapse but clinical and laboratory markers of recurrence are not well established. DESIGN AND METHODS In 109 patients enrolled in an international registry we evaluated, in the frame of a retrospective cohort study, the predictive role of the metalloprotease ADAMTS13...
BACKGROUND AND PURPOSE The association between family history of stroke and stroke recurrence remains unclear. METHODS Using a web-based multicenter stroke registry database, information on history of stroke in first-degree relatives was collected prospectively for acute ischemic stroke patients who were hospitalized within 7 days of onset. The collected information was categorized as follows...
BACKGROUND AND PURPOSE Published cohorts of children with arterial ischemic stroke (AIS) in the 1990s to early 2000s reported 5-year cumulative recurrence rates approaching 20%. Since then, utilization of antithrombotic agents for secondary stroke prevention in children has increased. We sought to determine rates and predictors of recurrent stroke in the current era. METHODS The Vascular Effe...
Purpose: Active specific immunotherapy (ASI) consisting of an autologous tumor cell vaccine given as adjuvant treatment has been shown to improve recurrence-free survival of patients with colon cancer. The aim of the current retrospective study was to investigate whether the beneficial effects of ASI given as adjuvant treatment correlated with microsatellite instability (MSI), which is consider...
BACKGROUND Tumour angiogenesis is the result of an inbalance between anti- and pro-angiogenic factors. CD105 (endoglin) is a component of the receptor complex of transforming growth factor (TGF-beta1). Vascular endothelial growth factor receptor 2 (VEGFR2 or Flk-1/KDR) belongs to the high-affinity VEGF receptors. The aim of the study was to investigate the expression, cellular localization and ...
BACKGROUND Circumferential pulmonary vein ablation (CPVA) has become common therapy for atrial fibrillation (AF), but results of large randomized controlled trials comparing this procedure with antiarrhythmic drug therapy (ADT) have not been published to date. We conducted a systematic literature review to assess whether CPVA is superior to ADT for the management of AF. METHODS We searched Pu...
Knowledge of stillbirth recurrence risk is of clinical interest and may give etiological insight. The authors studied "gestational age-" and "weight-by-gestation-specific" stillbirth recurrence, and evaluated time trends in a population-based cohort study from the Medical Birth Registry of Norway, from 1967 to 2004. Singleton births, including stillbirths from 20 weeks' gestation, were linked t...
Purpose: Serotonin (5-hydroxytryptamine, 5-HT) is well known for its growth stimulatory effect on several types of carcinoma and tumor cells. Since a large portion of 5-HT is stored and transported by platelets, the aim of this study was to assess the influence of platelet-sequestered 5-HT on post-resection hepatocellular carcinoma (HCC) recurrence. Methods: This pilot study was conducted in a ...
Data from our trial of periconceptional vitamin supplementation for the prevention of neural tube defects have been analysed to assess the influence of various factors on recurrence rates of neural tube defect. Our data suggest that the risk of recurrence of neural tube defect is influenced by the number of previous neural tube defects, area of residence, immediately prior miscarriage, and inte...
