Retreatment after LASIK is commonly performed by lifting the flap created during the first operation foll...
INTRODUCTION Gutta-percha must be removed from the root canal space during retreatment to ensure a more favorable outcome. The aim of this study was to compare the efficacy of hand instruments, RaCe and RaCe plus XP-endo finisher instruments in removal of gutta-percha from root canal walls during retreatment. METHODS AND MATERIALS Thirty single-rooted premolars were prepared, obturated, and d...
Successful retreatment with sofosbuvir plus ledipasvir for cirrhotic patients with hepatitis C virus genotype 1b, who discontinued the prior treatment with asunaprevir plus daclatasvir: A case series and review of the literature. Haga Y1, Kanda T1,2, Yasui S1, et al. Oncotarget. 2017 Dec 29;9(4):5509-5513. doi: 10.18632/oncotarget.23768. eCollection 2018 Jan 12. BACKGROUND: Interferon-free trea...
PURPOSE Ipilimumab is a fully human monoclonal antibody against cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) that has been shown to improve survival in patients with pretreated, advanced melanoma in a phase III trial. Some patients in this study who initially responded to ipilimumab treatment but later progressed were eligible for retreatment with their original randomized regimen. Here...
SETTING One reference and three zonal laboratories and 500 health facilities managing retreatment tuberculosis (TB) patients in Tanzania. OBJECTIVES The National Tuberculosis and Leprosy Programme (NTLP) requires that all notified cases of retreatment TB in Tanzania have sputum samples sent for culture and drug susceptibility testing (DST). This study determined 1) if the number of annually n...
INTRODUCTION Bacterial infection of tooth pulp can progress into periapical diseases. Root canal treatment has been established as the best treatment. In cases of failure, nonsurgical retreatment of teeth is preferred to surgical procedure and extraction. MATERIALS AND METHODS In this historical cohort study, 104 permanent teeth with apical lesion were treated during 2002-2008. All teeth show...
INTRODUCTION The success of endodontic retreatment is related to the complete removal of the obturation material from the root canal system. The aim of this study was to evaluate the efficacy of Mtwo R and ProTaper retreatment files in removing the Resilon/Epiphany system with or without chloroform during retreatment. MATERIALS AND METHODS Sixty distal roots of first mandibular molars were pr...
BACKGROUND In 2004, an anti-tuberculosis (TB) drug resistance survey in Heilongjiang province, China, enrolled 1574 (79%) new and 421 (21%) retreatment patients. Multi-drug resistant (MDR) TB was detected in 7.2% of new and 30.4% of retreatment patients. All received treatment with standardized first-line drug (FLD) regimens. METHODOLOGY/PRINCIPAL FINDINGS We report treatment outcomes of the ...
BACKGROUND AND AIMS Retreatment with a combination of alpha interferon (IFN) plus ribavirin of patients with chronic hepatitis C who did not respond to IFN monotherapy has not been assessed in large controlled studies. METHODS To assess the effectiveness and tolerability of IFN/ribavirin retreatment of non-responders to IFN and to identify predictors of complete (biochemical and virological) ...
Chronic Hepatitis C can progress to end-stage liver cirrhosis or hepatocellular carcinoma. Interferon (IFN) therapy is effective in clearing the hepatitis C virus and in improving liver histology, however, few patients maintain a sustained response (SR) after IFN withdrawal. Immediate retreatment with IFN is therefore considered to be both effective and necessary, especially for patients who do...
