Is there a right place to pace the right ventricle? Evaluation of apical and septal positions in a pacemaker population: Study protocol for a prospec…
2014
Abstract Introduction The main objective of research in pacemaker therapy has been to provide the best physiologic way to pace the heart. Despite the good results provided by right ventricular pacing minimization and by biventricular pacing in specific subsets of heart failure patients, these options present many limitations for standard pacemaker recipients. In these patients, pacing the right ventricle at alternative sites could result in a lower degree of left intraventricular dyssynchrony. Despite the lack of strong evidence and the difficulty in placing and accurately classifying the final lead position, pacing at alternative right ventricular sites seems to have become a standard proc…
Thermal Thresholds Predict Painfulness of Diabetic Neuropathies
2004
OBJECTIVE—Pathophysiology explaining pain in diabetic neuropathy (DN) is still unknown. RESEARCH DESIGN AND METHODS—Thirty patients with peripheral DN (17 men and 13 women; mean age 52.4 ± 2.5 years) were investigated. Fifteen patients had neuropathic pain, and 15 patients were free of pain. Patients were followed over 2 years and examined at the beginning and thereafter every 6 months. Clinical severity and painfulness of the DN were assessed by the neuropathy impairment score and visual analog scales (VASs). Cold and warm perception thresholds as well as heat pain thresholds were obtained for evaluation of Aδ- and C-fibers. Nerve conduction velocities (NCVs) and vibratory thresholds were …
Palatal positioned implants in severely atrophic maxillae versus conventional implants to support fixed full-arch prostheses: Controlled retrospectiv…
2014
Background: To evaluate soft tissue conditions and bone loss around palatal positioned implants supporting fixed full-arch prostheses to rehabilitate edentulous maxillae with horizontal atrophy and compare them with conventional well-centered implants placed in non-atrophic maxillae after a minimum follow-up of 5 years. Material and M ethods: A clinical retrospective study was performed of patients that were rehabilitated with full-arch fixed implant-supported maxillary prostheses and had a minimum follow-up of 5 years after implant loading. Patients were divided into 2 groups: patients with class IV maxilla according to Cawood and Howell and treated with palatal positioned implants (test) …
Survival of patients with spinal muscular atrophy type 1.
2013
BACKGROUND: Spinal muscular atrophy type 1 (SMA1) is a progressive disease and is usually fatal in the first year of life. METHODS: A retrospective chart review was performed of SMA1 patients and their outcomes according to the following choices: letting nature take its course (NT); tracheostomy and invasive mechanical ventilation (TV); continuous noninvasive respiratory muscle aid (NRA), including noninvasive ventilation; and mechanically assisted cough. RESULTS: Of 194 consecutively referred patients enrolled in this study (103 males, 91 females), NT, TV, and NRA were chosen for 121 (62.3%), 42 (21.7%), and 31 (16%) patients, respectively. Survival at ages 24 and 48 months was higher in …
Pain intensity as prognostic factor in cancer pain management
2015
Aim The aim of this study was to prospectively assess the prognostic value of initial pain intensity and its duration in advanced cancer patients. Methods A prospective study was conducted in a sample of patients with cancer requiring pain control. Patients underwent standard analgesic strategies used in our palliative care units. Pain intensity was measured at admission (T0) and after successful dose titration or opioid/route switching within a week (Ts). Patients were also asked about their pain intensity reported 15 days before admission (T-15). Doses of opioids and duration of opioid use were recorded. Patients were also assessed for the presence of incident pain, neuropathic pain, alco…
A nested case–control study: personal, social and environmental correlates of vigorous physical activity in adolescents with asthma
2014
Objective: Physical activity (PA) is associated with health benefits. Children and adolescents with asthma may be limited in their PA, particularly at vigorous intensity due to asthma symptoms or poor psychological adjustment to asthma. We aimed to investigate if self-perceived competence, enjoyment, support from others and social-physical environment were associated with vigorous physical activity (VPA) and secondarily to assess if such associations were modified by asthma and asthma severity. Methods: Data from a nested case–control study at 13 years of age within the birth-cohort Environment and Childhood Asthma Study were compiled from 95 participants with and 79 without asthma. The par…
Clinical effects of a Long-term Educational Program for Children with Asthma - Aironet®. A 1-yr randomized controlled trial
2009
Educational self-management programs for children with asthma have now become a routine feature in the management of the disease, as international guidelines underline. We designed this trial to find out whether Aironet, an educational program developed for children with asthma, influenced asthma severity and improved parents' knowledge of the disease. In a multicenter, prospective, randomized controlled trial we enrolled 123 children, 72 boys, mean age 8.78 yr (+/-2.33 s.d.), with intermittent or mild persistent asthma. Participants were randomly assigned to an education group, who received Aironet at baseline and 2 months later (60 children), or to a control group who did not (63 children…
Vascular damage and lack of angiogenesis in systemic sclerosis skin
2003
The aim of this study was to analyse microvascular damage and compensatory angiogenesis in skin from patients with systemic sclerosis (SSc) compared with systemic lupus erythematosus (SLE), Raynaud's phenomenon (RP) and healthy controls. Immunohistochemistry was used for skin biopsies (9 SSc, 10 SLE, 9 RP and 12 healthy controls) using von Willebrand factor and beta3 integrin subunit specific antibodies, TechMate immunostaining robot and biotin-streptavidin protocol. In the early stages of SSc, vWF was found in the perivascular space and interstitial matrix in papillary but not in the reticular dermis, in particular around small oedematous blood vessels infiltrated by mononuclear cells. The…
The correlation between the severity of radiotherapy-induced glossitis and endothelial cell injury in local tissues in a rat model.
2010
Objectives: To explore the correlation between the severity of radiotherapy-induced glossitis (RTG) and endothelial cell injury in local tissues in a rat model. Study Design: The RTG animal model was designed and used by our team. The Oral mucositis index(OMI) was documented daily. Immunohistochemistry (IHC) Staining of CD34 was utilized to identify endothelial cells in the RTG tissues. Apoptosis of endothelial cells in local lesions due to RTG was detected by the TUNEL assay. The dynamic relationship between the OMI and apoptotic endothelial cells was statistically analyzed by time. Results and Conclusions: The injury and apoptosis of endothelial cells were observed 3 day post-irradiation.…
Heterogeneity of atherosclerosis in mesenteric arteries and outgrowth remodeling
2009
Abstract Background In patients with acute mesenteric ischemia by occlusive thrombo-embolism, the superior mesenteric artery (SMA) is more affected than the inferior mesenteric artery (IMA). Methods This study investigated postmortem mesenteric arteries from aged subjects (n=21). Four atherosclerotic stages were defined by signs of degeneration and inflammation in sections stained with Elastica-van-Gieson and immunohistology, respectively. Results In females and males, Stages 3 and 4 were found in 62% of the SMA and 24% of the IMA. Lumenal areas based on diameter measurements remained essentially unchanged between Stages 1 and 4. Compared to a Stage 1 reference, remodeling was associated wi…
