The aim of this study was to investigate the demographic and clinical characteristics of patients with multiple sclerosis (MS) diagnosed between 1986 and 2015. 333 patients with definite MS were divided into four subgroups according to the following diagnostic criteria Group A) Poser (n = 145), Group B) McDonald 2000 (n = 66), Group C) McDonald 2005 (n = 62), and Group D) McDonald 2010 (n = 60). We investigated 1) patient sex and age at diagnosis, 2) symptoms and number of relapses that prompted MS diagnosis, 3) time between first symptoms suggestive of MS and confirmed diagnosis, and 5) Expanded Disability Status Scale (EDSS) score at disease onset. The overall female-to-male ratio was 2.31, but in the subgroups it differed significantly (A - 1.9; B - 1.6; C - 4.7; D - 3.6). The mean age at diagnosis (in years) decreased from 39.6 ± 13.3 in Group A to 29.9 ± 9.3 in Group D, p less then 0.001. Pyramidal signs remained the most common manifestation regardless of the diagnostic criteria, although an increased trend of visual dysfunction was observed (A - 16%, B - 14%, C - 19%, D - 23,3%; A vs D, p less then 0.001). PF06821497 The number of relapses before diagnosis decreased from median 4.0 to 2.5 in Group A and Group D, p less then 0.001. Time from the first symptom to diagnosis shortened from 88.9 ± 80.2 months (Group A) to 33.6 ± 68.2 months (Group D), p less then 0.0001. Mean EDSS score at diagnosis also decreased A - 4.4 ± 2.3; B - 3.1 ± 1.7; C - 2.7 ± 1.3; D - 2.8 ± 1.4, p less then 0.001. Our study indicates significant differences in demographic and clinical characteristics of MS diagnosed according to the changing criteria.INTRODUCTION Marfan syndrome (MFS) and related connective tissue disorders (CTDs) are increasingly recognised. Genetic testing has greatly improved the diagnostic outcome/power over the last two decades. In this study we describe a multicentre cohort of adults with MFS and related CTDs, with a particular focus on results from genetic testing. METHODS All patients with MFS and related CTDs were identified from the databases of five centres in the canton of Zurich. Echocardiographic and clinical findings including systemic Marfan score, use of medication and genetic results were retrospectively analysed. MFS was diagnosed using the revised Ghent criteria (including FBN1 genetic testing if available); other CTDs (Loeys-Dietz syndrome) were diagnosed by genetic testing only. RESULTS A cohort of 103 patients were identified (62 index patients, 41 relatives of family members) 96 patients with MFS and 7 patients with other CTD, 54 males (52%), median age 23 years (range 1–75). The median systemic Marfan score was 5 fulfilling the revised Ghent criteria for MFS underwent genetic testing, often leading to or confirming the diagnosis of MFS. Other CTDs could be discriminated best by genetic testing. With respect to the diagnosis of MFS and related CTDs, the usefulness of the systemic score is limited, showing the importance of genetic testing, which enabled definitive diagnosis in 95% of tested patients. Patient education on medical treatment still has to be improved.

Little evidence is available on their epidemiology, diagnosis and therapy. We aimed to evaluate current practices and provide recommendations. METHOD We systematically reviewed articles from PubMed, Embase, OVID-Medline and the Cochrane Library. RESULTS Forty-four publications reported pneumothoraces after ERCP in 49 patients (74% females). Twenty-one patients (43%) had atypical gastrointestinal anatomy, including peri-ampullary diverticula (n = 8), surgical or endoscopic alterations (n = 7), local tumours (n = 3), ulcerations (n = 2) and ectopic papilla (n = 1). Precut (14%) or standard (39%) sphincterotomies were performed. Cannulation was unsuccessful in six ERCPs. Pneumothoraces occurred bilaterally (45%), on the right (37%) or left side (6%), or no side was stated (12%). Nineteen tension pneumothoraces occurred. Perforations were mainly caused by the sphincterotome, peri-ampullary (41%), or the endoscope, distant from the papilla of Vater (23%). Pneumothoraces were sometimes diagnosed only after hospital discharge (14%). Eighteen patients underwent surgical therapy with drainage, repair and/or bypass. Conservative treatment included antibiotics and bowel rest. Most pneumothoraces were drained; 14% resolved without pleural drainage. Overall mortality was 4%. The mean hospital stay was 9.8 days. CONCLUSIONS A post-ERCP pneumothorax should be considered when subcutaneous emphysema, cardiovascular instability or respiratory distress occurs. Thoraco-abdominal computed tomography facilitates identification and therapy tailoring. Because of possible late or discrete onset, patients should be monitored carefully.When surgery is needed for chronic low back pain, replacement of the degenerated and potential pain generating disc with a prosthesis often gives good short-term pain relief. However, there is no evidence of the clinical superiority of prosthesis compared with other treatments. Disc prosthesis is associated with considerable risks of late severe complications, especially in revision surgery. The method has been suggested as a treatment for young active patients, which is highly questionable considering the risk of late severe adverse events and complex revision surgery. Globally the method is declining and in many health care financing models it is not an approved treatment. In Sweden, the use of disc prosthesis is increasing.Importance Atrial fibrillation (AF) affects more than 6 million people in the United States; however, much AF remains undiagnosed. Given that more than 265 million people in the United States own smartphones (>80% of the population), smartphone applications have been proposed for detecting AF, but the accuracy of these applications remains unclear. Objective To determine the accuracy of smartphone camera applications that diagnose AF. Data Sources and Study Selection MEDLINE and Embase were searched until January 2019 for studies that assessed the accuracy of any smartphone applications that use the smartphone's camera to measure the amplitude and frequency of the user's fingertip pulse to diagnose AF. Data Extraction and Synthesis Bivariate random-effects meta-analyses were constructed to synthesize data. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) of Diagnostic Test Accuracy Studies reporting guideline. Main Outcomes and Measures Sensitivity and specificity were measured with bivariate random-effects meta-analysis.
