STUDY OBJECTIVE To assess the outcome after retreatment of patients with small cell lung cancer (SCLC) who redevelop small cell cancer (SCC) 2 or more years after initial therapy. DESIGN Retrospective analysis. SETTING Single government institution: the National Cancer Institute. PATIENTS Twenty patients who redeveloped SCC among 65 patients who survived 2 or more years after starting tre...
[Refractional results of LASIK retreatment with wavefront-guided ablation versus standard ablation].
PURPOSE To evaluate refractive outcomes of wavefront-guided LASIK (Zyoptix, Bausch & Lomb) versus standard LASIK (PlanoScan, Bausch & Lomb) in retreatment of primary LASIK for myopia and myopic astigmatism. METHODS A prospective, randomized trial with paired eye control of 74 eyes from 37 patients who underwent LASIK retreatment was performed. Each patient underwent retreatment using Zyoptix ...
OBJECTIVE To evaluate the efficacy and safety in the long term of a retreatment regimen with Rituximab (RTX) alone administered at clinical relapse in cryoglobulinemic vasculitis (CV). METHODS Thirty patients with severe HCV-related CV, previously enrolled in the multicentre Italian trial on RTX in the treatment of CV, were retrospectively evaluated after the end of the trial. All of them wer...
mandibular premolars have earned a reputation for having aberrant anatomy. the occurrence of three canals with three separate foramina in mandibular premolars is very rare. if predictable treatment of a three rooted mandibular premolar is planned, precise knowledge of clinical and radiographic anatomy is absolutely necessary. these teeth may also require special shaping and obturating technique...
instrument breakage during treatment can lead to serious complications and carries the risk of treatment failure. when a file breaks in the canal, bypassing or removal can be difficult and the long-term prognosis of the tooth may be compromised. sometimes surgery may be indicated for removal of the broken segment. often some part of the root cannot be cleaned because of blockage by the broken f...
The aim of this study was to evaluate the effect using a higher rotation speed with XP-endo Shaper (XPS) on apically extruded debris and operation time during endodontic treatment retreatment procedures. Sixty mesial roots mandibular first molar teeth were randomly assigned four groups (Initial groups: XPS used at 1000 or 3000rpm speeds Retreatment speeds). During initial procedures preweighed ...
BACKGROUND In recent years, drug resistant tuberculosis (DR-TB) particularly the emergence of multi-drug-resistant tuberculosis (MDR-TB) has become a major public health issue. The most recent study regarding the prevalence of drug-resistant tuberculosis in mainland China was a meta-analysis published in 2011, and the subjects from the included studies were mostly enrolled before 2008, thus mak...
BACKGROUND Brentuximab vedotin is a CD30-directed antibody-drug conjugate. Retreatment with brentuximab vedotin monotherapy was investigated in patients with CD30-positive Hodgkin lymphoma (HL) or systemic anaplastic large cell lymphoma (ALCL) who relapsed after achieving complete or partial remission (CR or PR) with initial brentuximab vedotin therapy in a previous study (ClinicalTrials.gov NC...
