BACKGROUND: The pucker sign, also called skin tenting, indicates significant displacement of the supracondylar fracture and can be a cause for alarm. The purpose of this study is to compare a cohort of patients with type III supracondylar fractures presenting with a pucker sign to a group without a pucker sign by evaluating neurovascular injury at presentation, need for open reduction, persistent neurovascular injury, range of motion, and carrying angle at final follow-up. METHODS: A retrospective review was performed for Gartland type III extension type supracondylar fractures...

BACKGROUND: The cross-sectional area (CSA) of a material is used to calculate stress under load. The mechanical behaviour of soft tissue is of clinical interest in the management of injury; however, measuring CSA of soft tissue is challenging as samples are geometrically irregular and may deform during measurement. This study presents a simple method, using structured light scanning (SLS), to acquire a 3D model of rabbit Achilles tendon in vitro for measuring CSA of a tendon. METHOD: The Artec Spider™ 3D scanner uses structured light and stereophotogrammetry technologies to acquire shape data and reconstruct a 3D model of an object...

Regeneration of injuries at tendon-to-bone interface (TBI) remains a challenging issue due to the complex tissue composition involving both soft tendon tissues and relatively hard bone tissues. Tissue engineering using polymeric/ceramic composites has been of great interest to generate scaffolds for tissue's healing at TBI. Herein, we presented a novel method to blend polymers and bioceramics for tendon tissue engineering application. A homogeneous composite comprising of nanohydroxyapatite (nHA) particles in poly(ε-caprolactone) (PCL) matrix was obtained using a combination of solvent and mechanical blending process...

Precise measurement of cadaver decomposition rate is the basis to accurate post-mortem interval (PMI) estimation. There are many approaches explored in recent years, however, it is still unsolved completely. Total volatile basic nitrogen (TVB-N), which is an important index to predict meat freshness and shelf life in food science, could serve as an indicator for measuring PMI associated decomposition rate of cadavers. The aim of this work was to establish a practical method to determine TVB-N in cadaver soft tissues (mainly skeletal muscle) for measuring decomposition rate...

Extramedullary relapse (EMR) represents a poor prognostic marker in the course of multiple myeloma (MM). We reviewed data from 329 patients, diagnosed between 2000 and 2010, without extramedullary disease at onset to explore possible risk factors for EMR. The median overall survival of our study cohort was 6.4 years. The risk of EMR was 28 % with a median time from diagnosis to first EMR of 2.2 years (0.2-9.1 years). Patients with soft tissue masses located in extra-osseous organs (EMR-S) showed the worst outcome, compared to those with tumor masses arising from adjacent bone (EMR-B) (median OS 1...

PURPOSE: After reconstructing a torn ACL with a soft tissue allograft, the long-term healing process of graft maturation following the short-term healing process of graft incorporation into the bone tunnels might lead to recurring instability and concomitant decreases in the activity level, function, and patient satisfaction. Relying on roentgen stereophotogrammetric analysis (RSA), the primary purpose was to determine whether anterior laxity increased and whether patient-reported outcomes declined between 1 and 7 years for a particular graft construct, surgical technique, and rehabilitation programme...

One of the most impressive soft tissue injuries is the facial degloving, normally associated with industrial machines and traffic accidents. This injury is characterized by the separation of the skin and cartilage from the bones, compromising the soft tissues correlated in the trauma area, nerves, and blood vessels. A 28-year-old patient, male, was referred to Araçatuba's Santa Casa Hospital, after a motorcycle accident, hitting his face on the sidewalk. The patient was conscious, oriented, denying fainting and unconsciousness during the accident, and complaining of pain in the nasal region of the face...

Background Lateral malleolar fractures (Weber type B or OTA 44-B) account for 60% of all ankle fractures. To achieve anatomic restoration, surgical stabilization provides better results than conservative treatment. Various fixation methods are available to treat these fractures; however, the best method is still unknown. Our objectives were to present a new, useful, and efficient surgical technique for stabilizing lateral malleolar fractures and to analyze the outcomes of patients treated with the compression cerclage system...

BACKGROUND: When primary root canal therapy fails, periapical lesions can be retreated with or without surgery. Root canal retreatment is a non-surgical procedure that involves removal of root canal filling materials from the tooth, followed by cleaning, shaping and obturating of the canals. Root-end resection is a surgical procedure that involves exposure of the periapical lesion through an osteotomy, surgical removal of the lesion, removal of part of the root-end tip, disinfection and, commonly, retrograde sealing or filling of the apical portion of the remaining root canal...

: BACKGROUND Often breastfeeding problems experienced by mothers and their babies may be attributed to the abnormal attachment of the infant's tongue (ankyloglossia) and/or maxillary lip-tie. Proper breastfeeding depends upon an infant's ability to correctly latch onto its mother's breast. If born with oral soft tissue abnormalities such as tongue-tie or lip-tie, it may be almost impossible for the infant to breastfeed. During the oral evaluation of an infant presenting with breastfeeding problems, one factor that is often overlooked and undiagnosed - and thus untreated - is the attachment of the upper lip to the maxillary gingival tissue...

Biofilms have a tremendous impact on industrial machines working in moist environments, while in biological systems their effect is further complicated by the host's response.Implant-related infections are a complex process, starting with bacterial adhesion and biofilm formation, followed by the variable interaction between host, implant, microorganisms and their by-products. Depending on the balance of these factors, different clinical presentations are observed, which may eventually, at times, shift from one into the other...

INTRODUCTION: One of the most important complications of orbital floor fractures is diplopia and restricted ocular movement. The role of the volume of soft tissue herniation on these clinical symptoms after orbital floor fractures is unclear and potentially may predict development of persistent clinical symptoms. Therefore the aim of this study was to assess pre- and postoperative complications associated to the volume of soft tissue herniation, with special interest to diplopia and bulbus motility impairment...

The gold standard to arrange impacted teeth in the dental arch is represented by a surgical approach followed by orthodontic traction force application. In the literature, many surgical approaches are proposed to reach such a scope. The aim of the present study is to demonstrate how laser technique could positively assist surgical approaches.Study population was composed by 16 patients undergoing orthodontic treatment of 20 impacted teeth. In 10 patients (population A) surgical exposure of the impacted teeth was performed using a 980 nm diode laser, while in the other 10 patients (population B), surgical incision was performed using a traditional lancet...

Resurfacing large facial defect is a continuing challenge for plastic surgeons. Skin graft or free flap is hard to obtain satisfactory results or is beyond the skill of most surgeons. The authors performed 13 expended submental island flaps to resurface middle and lower facial defects and achieved satisfactory results. In the first stage operation, the authors implanted one soft tissue expander in the anterior neck region which was expanded over an average of 3 months. In the second stage operation, the authors elevated the expanded submental island flap to resurface facial defect...
