Comparison of pain threshold,health and functional status of females with fibromyalgia and multiple sclerosis: a pilot study

Objectives. Fibromyalgia (FM) and multiple sclerosis (MS) are known to cause disability and have an impact on physical functioning, social functioning, and emotional well-being of affected individuals. The aim of this study was to compare pressure pain threshold, health and functional status in females with FM and MS who were ambulatory. Methods. Control point scores (CPS), total myalgic scores (TMS; using an algometer), tender point (TP) counts, and chronic widespread pain were assessed in females with FM and MS and in healthy age-matched female controls. The Fibromyalgia Impact Questionnaire (FIQ), and the Nottingham Health Profile were performed. The Kurtzke Expanded Disability Status Scale (EDSS) was used to estimate the disability status of persons with MS. Results. Fibromyalgia patients have significantly lower CPS and TMS than MS patients and controls. Multiple sclerosis patients had similar CPS but significantly lower TMS compared to controls. Tender point counts were significantly higher in FM than MS patients and controls. Patients with MS had a higher numbers of TPs with respect to controls. Chronic widespread pain was reported by only three patients with MS and these patients did not meet FM criteria for tender point counts. Fibromyalgia patients had significantly lower FIQ-first item scores than MS patients. FM patients had higher NHP section scores in pain, social isolation, emotional reaction, sleep and energy, but similar physical mobility compared to MS patients. In MS patients energy and physical mobility dimension of NHP and FIQ-first item scores correlated with EDSS (r=0.42, P=0.047, r=0.83, P=0.001, and r=0.62, P=0.001, respectively). Conclusion. This cross-sectional study warrants further research comparing FM and MS, which share a lot of clinical and psychosocial features or may coexist. Chronic pain and related fatigue, social and emotional reactions and disability seem to be important components in FM, so taking care of these components, in other words a biopsychosocial model, may improve disease outcome and quality of life not only in FM but also in MS.     

Effect of Agitation of EDTA with 808-Nanometer Diode Laser on Removal of Smear Layer

Introduction

Near-infrared diode lasers can be used for several applications, which range from disinfection to smear layer removal in endodontics. This study evaluated the efficacy of agitation of 15% EDTA with an 808-nm diode laser on removal of the smear layer.

Methods

Sixty extracted human maxillary central incisor teeth were instrumented up to ProTaper F4 (Dentsply Maillefer, Ballagues, Switzerland) and then randomly divided into 6 groups (n = 10 for each group) according to the different final irrigating protocols as follows: 5% sodium hypochlorite for 120 seconds performed with the NaviTip (Dentsply Maillefer, Ballaigues, Switzerland) (control group); 15% EDTA for 120 seconds performed with the NaviTip; and agitation of 15% EDTA with an 808-nm diode laser for 10, 20, 30, and 40 seconds. Specimens were observed under a scanning electron microscope, and open dentinal tubules were counted using Adobe Photoshop software (Adobe Systems, San Jose, CA). The data were analyzed with 1-way analysis of variance and Tukey post hoc tests (P = .05).

Results

The number of open dentinal tubules was higher in the middle thirds than in the apical thirds. The differences between the apical and middle thirds were statistically significant (P < .05). Statistically significant differences were also found between the control group and the other groups in both the middle and apical thirds of the root canals (P < .05).

Conclusions

The results indicated that agitation of 15% EDTA with an 808-nm diode laser for 20 seconds was effective in removing the smear layer in the apical thirds of root canals.     

Comparison of two implant-supported molar distalization systems

Objective:To examine skeletal, dental, and soft tissue effects of the Miniscrew Implant Supported Distalization System (MISDS) and the Bone-Anchored Pendulum Appliance (BAPA).Materials and Methods:Among 28 patients displaying Angle Class II malocclusion, 14 patients with a mean age of 14.8 ± 3.6 years treated with MISDS were included in the first group, and 14 patients with a mean age of 14.5 ± 1.5 years treated with BAPA were included in the second group. The pretreatment and posttreatment lateral cephalograms were analyzed. Statistical evaluation was carried out using the paired Shapiro-Wilk test, the paired-sample t-test, and the unpaired t-test.Results:Upper posterior teeth were distalized successfully in both groups. Nearly bodily distalization was seen in the MISDS group, whereas significant distal tipping of the upper first molars was observed in the BAPA group (P < .001). There were no statistically significant changes in the sagittal position of the maxilla and mandible and in the position of the upper incisors as a result of treatment in either group.Conclusions:Both methods provided absolute anchorage for distalization of posterior teeth; however, almost translatory distal movement was encountered in the MISDS group, and substantial distal tipping of the maxillary molars accompanied distalization in the BAPA group.     

Ectopic Primary B Cell Lymphoma of the Thyroid Presenting as an Anterior Mediastinal Mass. A Case Report

Ectopic thyroid tumours arising in the mediastinum without connection to the cervical thyroid gland are very rare. Follicular adenoma, papillary carcinoma and follicular carcinoma in the mediastinum has been reported, but primary ectopic thyroid B cell lymphoma has not been reported previously. We report mediastinal primary ectopic thyroid large B cell lymphoma in an 80-year-old man. Differential diagnosis from primary mediastinal large B cell lymphoma and clinicopathologic features are discussed.     

Dilatation of the ascending aorta and serum alpha 1-antitrypsin level in patients with bicuspid aortic valve

Predictors of aortic dilatation are not well described in patients with bicuspid aortic valves (BAV). This study sought to examine the relationship between proximal aortic dilatation and matrix metalloproteinase-9 (MMP-9) and alpha 1-antitrypsin (α1AT) levels in patients with BAV. All patients underwent echocardiography using a standard protocol, and aortic measurements were taken in end-diastole. We studied 82 patients with BAV and categorized them into two groups according to aortic dimensions corrected for body surface area and age. The plasma level of α1AT was routinely determined using a BN ProSpec analyzer (Siemens Healthcare Diagnostics, Marburg, Germany), and that of MMP-9 were determined by ELISA (RayBiotech Inc. Norcross, GA, USA). Statistical analysis was performed using the Statistical Package for Social Sciences (SPSS; SPSS Inc., Chicago, IL, USA) software for Windows version 12. This study included patients with BAV with no or mild valvular impairment. There were no significant differences between groups in terms of gender, body surface area, associated hypertension, diabetes mellitus, hyperlipidemia, or smoking. The mean ascending aortic diameter was 4.38?±?0.5?mm in group 1 and 3.34?±?0.35?mm in group 2 (p?相似文献   

Early-mid term follow-up results of percutaneous closure of the interatrial septal defects with occlutech figulla devices: a single center experience

Background: Percutaneous closure of secundum type atrial septal defect (ASD) and patent foramen ovale (PFO) has gained widespread use in recent years. Herein, we evaluated the safety and efficacy of the Occlutech® Figulla devices for PFO and ASD closure in a reference tertiary center. Methods: All 143 patients (46.9% male, mean age 39.3 ± 12.2 years) who underwent transcatheter PFO (n = 85) and ASD (n = 58) closure with Occlutech® Figulla devices between February 2009 and October 2011 were included in this study. An echocardiographic follow‐up examination was performed at the 1st, 6th, and 12th month visits. Results: The devices were successfully implanted in all 143 patients (100%). In‐hospital periprocedural complications were device embolization (0.7%; 1 ASD patient), atrial fibrillation (1.4%; 1 ASD and 1 PFO patients), supraventricular tachycardia (0.7%; 1 PFO patient), and vascular access hematoma (0.7%; 1 ASD patient). Among ASD patients, 2 patients had trivial (jet width <1 mm in diameter) and 1 patient had small (1–2 mm) residual shunts before hospital discharge, which disappeared after the 6‐month visit. During the mean 15.4 ± 9.6 months follow‐up, all patients were asymptomatic and no ischemic stroke, cardiac perforation, device erosion, embolization, thrombus formation, or malposition of the device was observed. Conclusions: Percutaneous PFO and secundum type ASD closure with the novel Occlutech® Figulla Occluder devices without left atrial central pin and with significantly reduced meshwork was safe, feasible, and effective.

Impact of age,race and decade of treatment on overall survival in a critical population analysis of 40,000 multiple myeloma patients

With the availability of novel agents, the overall survival (OS) in patients diagnosed with multiple myeloma (MM) has improved over the last decade. Data on 40,294 MM patients in the years from 1973 to 2003 were obtained from the Surveillance, Epidemiology, and End Results Program (SEER) of the US National Cancer Institute. Statistical analyses evaluating gender, race, age, and year of diagnosis were performed using univariate and multivariate Cox regression models for the OS endpoint. The mean patient age at diagnosis was 68.3 years. Mean survival was 30 months (median = 19 months). Asian/Pacific Islander race was associated with an improved OS, HR 0.90 (CI 0.86–0.95, P < 0.001). American Indian/Alaska Native race was associated with a decreased OS, HR 1.18 (CI 1.01–1.38, P = 0.040). Multivariate analysis did not reveal statistically significant differences in OS between patients in the white and black race (P = 0.709). Younger age (age <65, and 65–75) was associated with improved OS when compared with patients >75 years of age (all P < 0.001). Recent treatment decades (1983–1992 and 1993–2003) were associated with improved OS on multivariate analysis with HR 0.88 (CI 0.88–0.89, P < 0.001) and HR 0.83 (CI 0.81–0.85, P < 0.001), respectively. As the largest population analysis to date, this study reveals a statistically significant improvement in OS for patients who were treated in more recent decades, even before the availability of novel agents. Patients who were <65 years of age and Asian/Pacific Islander race groups exhibited superior levels of OS, whereas American Indian/Alaska Native groups had decreased OS.     

Aortitis in a patient with psoriatic arthritis

Aortitis, inflammation of the aortic tissue, is most commonly caused by vasculitic rheumatic conditions, and less frequently infectious organisms. Involvement of the aorta is well defined in HLA-B27-associated spondyloarthropathies such as long-standing ankylosing spondylitis and Reiter's syndrome. However, unlike other spondyloarthropathies, aortic involvement or true aortitis is not a feature of psoriatic arthritis and has been reported in only a few cases. Herein, we report the case of a 22?year-old woman with psoriatic arthritis who developed descending aortitis while using tumor necrosis factor inhibitors.
