OBJECTIVES The aim of this in vitro study was to compare the efficacy of two retreatment rotary systems in the removal of Gutta-percha (GP) and sealer from the root canal walls with or without solvent. MATERIALS AND METHODS Forty-eight extracted human mandibular first premolars were prepared and obturated with GP and AH Plus sealer. Samples were then randomly divided into four groups. Group I...
INTRODUCTION The burden of MDR-TB is unknown in areas that do not have drug susceptibility testing (DST), but its frequency is expected to be higher in previously treated cases. Where DST is not available the WHO recommended standardized retreatment (Category II) regimen is given to previously treated TB patients OBJECTIVE To evaluate the frequency and pattern of drug resistance of Mycobacter...
Patients with chronic hepatitis C virus (HCV) infection and disease-related complications - among them cirrhosis and liver failure - pose a particular management challenge. Some of these patients may fail to respond to current therapy (non-responders), and some are affected so severely that treatment puts them at an unacceptable risk for complications. Treatment with pegylated interferon (peg-I...
INTRODUCTION The maximum removal of root canal filling material is essential for successful endodontic retreatment. The purpose of this study was to assess the efficacy of 2 reciprocating systems (Reciproc [VDW, Munich, Germany] and WaveOne [Dentsply Maillefer, Ballaigues, Switzerland]) compared with a nickel-titanium (NiTi) rotary system (ProTaper Universal Retreatment [Dentsply Maillefer]) in...
Background This study evaluated the risk factors of long-term mortality after loss to follow-up (LTFU) in patients with multidrug/rifampicin resistant tuberculosis (MDR/RR-TB) South Korea. Methods was a retrospective longitudinal using an integrated database constructed by data linkage three national databases, which include 7226 cases MDR/RR-TB notified between 2011 and 2017 Post-treatment out...
BACKGROUND Few data are available on the virological and clinical outcomes of advanced liver disease patients retreated after first-line DAA failure. AIM To evaluate DAA failure incidence and the retreatment clinical impact in patients treated in the advanced liver disease stage. METHODS Data on HCV genotype, liver disease severity, and first and second line DAA regimens were prospectively ...
SETTING Guguletu and Nyanga areas of Cape Town, South Africa. OBJECTIVE To evaluate the affordability and cost-effectiveness of community involvement in tuberculosis (TB) care. DESIGN A cost-effectiveness analysis comparing treatment for new smear-positive pulmonary and retreatment TB patients in two similar townships, one providing clinic-based-care with community-based observation options...
BACKGROUND AND PURPOSE The degree of variation in retreatment decisions for residual or recurrent aneurysms among endovascular therapists remains poorly defined. We performed a multireader study to determine what reader and patient variables contribute to this variation. MATERIALS AND METHODS Seven endovascular therapists (4 neuroradiologists, 3 neurosurgeons) independently reviewed 66 cases ...
AIM To describe the burden of tuberculosis (TB) in Cape Town by calculating TB incidence rates stratified by age and HIV-status, assessing the contribution of retreatment disease and estimating the cumulative lifetime TB risk in HIV-negative individuals. METHODS Details of TB cases were abstracted from the 2009 electronic TB register. Population denominators were estimated from census data an...
Introduction: Differentiated thyroid carcinoma (DTC) follow-up after thyroidectomy and radioiodine-ablation is performed mainly by thyroglobulin (Tg), diagnostic iodine-131 whole body scan (DxWBS) and sonography. Some patients with undetectable Tg have thyroid-bed uptake after ablation in whom decision making regarding the need for retreatment is still controversial. Methods: In this study, we ...
