Improved single visit management of old infected iatrogenic root perforations using Biodentine ®

ConclusionsIn single visit treatments, Biodentine seems to provide a biocompatible and effective seal in acidic environment, in accidental root perforations, even if the treatment is performed by an inexperienced operator and regardless of the location, the size and the time of occurrence of the perforation.

The objective of this study is to develop a composite bioactive scaffold composed of polylactide-coglycolide (PLGA) and tricalcium phosphate (TCP) (the basic carrier) incorporating osteogenic, bioactive magnesium metal powder (Mg).MethodPorous PLGA/TCP scaffolds incorporating Mg were fabricated using a low-temperature rapid-prototyping process. We term this the PLGA/TCP/Mg porous scaffold (hereafter, PPS), and the PLCA/TCP scaffold lacking Mg served as the control material when evaluating the efficacy of PPS. A total of 36 New Zealand white rabbits were randomly divided into blank, PLGA/TCP and PPS group, with 12 rabbits i...

Jnl Wrist Surg DOI: 10.1055/s-0038-1668153 Purpose The relationship between triangular fibrocartilage complex (TFCC) tear and ulnar impaction syndrome has not been fully understood. We hypothesized that a TFCC tear could change the ulnar variance, which may be the cause of ulnar impaction syndrome. Patients and Methods A total of 72 patients who underwent TFCC foveal repair between January 2011 and June 2016 were included in this retrospective study. Among them, 44 patients diagnosed with TFCC foveal tear with distal radioulnar joint instability and no ulnar impaction syndrome underwent TFCC foveal repair o...

Publication date: Available online 6 August 2018Source: Journal of Pediatric Surgery Case ReportsAuthor(s): Pilar Anton-Martin, Brigham C. Willis, John J. Nigro, Katie Budolfson, Dannah Raz, Ramin JamshidiAbstractComplete aortic transection is typically fatal and extremely rare in pediatric patients. High clinical suspicion, even in hemodynamically stable patients, is essential for timely recognition and intervention. There is scant literature on the management of complete aortic transection in pediatric patients. Retrospective chart review of an adolescent who survived a large complete thoracic aortic rupture along with s...

AbstractOsteogenesis imperfecta (OI) is a rare heritable skeletal dysplasia mainly caused by type I collagen abnormalities and characterized by bone fragility and susceptibility to fracture. Over 85% of the patients carry dominant mutations in the genes encoding for the collagen type I α1 and α2 chains. Failure of bone union and/or presence of hyperplastic callus formation after fracture were described in OI patients. Here we used theCol1a2+/G610C mouse, carrying in heterozygosis the α2(I)-G610C substitution, to investigate the healing process of an OI bone. Tibiae of 2-month-oldCol1a2+/G610C and wild-typ...

AbstractPurposeTo determine the clinical and radiographic efficacy of chitosan-glycerol phosphate/blood implant versus hyaluronic acid-based cell-free scaffold in patients with focal osteochondral lesion of the knee joint.MethodsClinical data of 46 patients surgically treated using either chitosan-glycerol phosphate/blood implant (25 patients, Group 1) or hyaluronic acid-based cell-free scaffold (21 patients, Group 2) in combination with microfracture were retrospectively evaluated. All lesions were Outerbridge grade III or IV with a mean lesion size of 3.3  ± 0.7 cm2. The mean follow-up time was ...

Excessive retroversion of the glenoid can cause eccentric loading of the glenohumeral joint and may lead to posterior shoulder instability, posterior labral tears, functional impairment, static posterior shoulder subluxation, and progressive glenohumeral arthropathy. For young patients surgical options are limited and include open labral repair and capsular plication, arthroscopic labral repair and capsular plication, or open posterior opening-wedge glenoid osteotomy. Of these, only the osteotomy can correct the glenoid retroversion and recenter the humeral head. Here, we detail our preoperative work-up, the surgical techn...

Background: Juvenile osteochondritis dissecans of the talus (JOCDT) is a focal idiopathic lesion primarily of the subchondral bone leading to subsequent cartilaginous damage. The majority of the papers dealing with JOCDT reported heterogeneous case studies of patients treated with different cartilage repair techniques. The purpose of this paper is to retrospectively review both clinical and radiologic results among 7 patients affected by JOCDT treated with arthroscopic bone marrow aspirate concentrate (BMAC) transplantation with the 1-step technique. Methods: Both standard anterior-posterior and lateral radiographs an...

Preliminary evidence suggests that AR-V7-positive tumors may be enriched for DNA-repair defects, perhaps rendering them more sensitive to immune-...
