We have previously shown that low frequency ultrasound can release biomarkers from cells into the murine circulation enabling an amplification and localization of the released biomarker that could be used as a blood-based method to detect cancer earlier and monitor therapy. In this study, we further demonstrate that this technique could be used for characterization of tumors and/or identification of cellular masses of unknown origin due to the release of multiple protein and nucleic acid biomarkers in cells in culture, mice and patients...

Nowadays, bioactive glasses (BGs) are mainly used to improve and support the healing process of osseous defects deriving from traumatic events, tumor removal, congenital pathologies, implant revisions, or infections. In the past, several approaches have been proposed in the replacement of extensive bone defects, each one with its own advantages and drawbacks. As a result, the need for synthetic bone grafts is still a remarkable clinical challenge since more than 1 million bone-graft surgical operations are annually performed worldwide...

Skin necrosis overlying an arteriovenous fistula at the cannulation site is a common and potentially life-threatening problem, often associated with underlying aneurysm formation. Arteriovenous fistula-skin necrosis generally requires resection of surrounding skin margins and the underlying aneurysmal vessel wall, allowing repair with healthy tissue of the arteriovenous fistula in addition to closure of soft tissue and skin. In patients with insufficient fistula length, salvage of these arteriovenous fistulas may result in difficult or insurmountable cannulation issues leading to attempts at one-needle cannulation dialysis or, most often, catheter placement...

BACKGROUND: Bowel dilatation is a common adaptive mechanism after intestinal resection. The symptomatic dilated dysmotile duodenum is difficult to manage, since conventional bowel tailoring and lengthening techniques are potentially hazardous because of the anatomy of the duodenal blood supply, the proximity to the pancreas, and the risk of injury to the common bile duct. METHODS: A 2-month-old child with short bowel and a symptomatic massively dilated duodenum was treated with a Transverse Flap Duodenoplasty (TFD)...

OBJECTIVE: Loss of teeth frequently results in compound horizontal and vertical alveolar bone defects. An appropriate bone structure is the key for implant placement and bony support of soft tissues. Advanced bone augmentation techniques are required for the reconstruction of these defects. This report will present a new bone block grafting technique with 12-month follow-up. METHOD: The seedling technique was used to augment the alveolar bone 3-dimensionally with autologous bone block and an osseointegrated implant in a 2-stage procedure...

Treatment of traumatic bone defects is dictated by a multitude of clinical factors including the defect size, patient comorbidities, soft tissue condition, and the possibility of infection present in the defect. With a variety of treatment strategies described, it is critical to choose the approach that will maximize outcomes in addressing this difficult problem. When addressing small-scale defects, bone grafting is the primary treatment. For large-scale defects, there are two major options to consider: induced membrane technique and distraction osteogenesis...

In this methodological study, we demonstrated the relevance of 3D imaging performed at various scales for the ex vivo detection and location of cerium oxide nanomaterials (CeO2 -NMs) in mouse lung. X-ray micro-computed tomography (micro-CT) with a voxel size from 14 µm to 1 µm (micro-CT) was combined with X-ray nano-computed tomography with a voxel size of 63 nm (nano-CT). An optimized protocol was proposed to facilitate the sample preparation, to minimize the experimental artifacts and to optimize the contrast of soft tissues exposed to metal-based nanomaterials (NMs)...

Fluorescence imaging is a well-established optical modality that has been used to localize and track fluorophores in vivo and has demonstrated great potential for surgical guidance. Despite the variety of fluorophores currently being researched, many existing intraoperative fluorescence imaging systems are specifically designed for a limited number of applications. We present a modular wide-field fluorescence overlay tissue imaging system for intraoperative surgical guidance that is comprised of commercially available standardized components...

BACKGROUND: Navigation-assisted resection has been proposed as a useful adjunct to resection of malignant tumors in difficult anatomic sites such as the pelvis and sacrum where it is difficult to achieve tumor-free margins. Most of these studies are case reports or small case series, but these reports have been extremely promising. Very few reports, however, have documented benefits of navigation-assisted resection in series of pelvic and sacral primary tumors. Because this technology may add time and expense to the surgical procedure, it is important to determine whether navigation provides any such benefits or simply adds cost and time to an already complex procedure...

Operative treatment of the unstable shoulder historically has a high success rate. However, the complication rate has risen. This article reviews the pearls and pitfalls to attempt to elucidate the etiology for these complications and failures. Preoperative assessment of the unstable shoulder ultimately is critical to avoid complications, including history, physical examination, and key radiographic features. Intraoperative techniques include appropriate soft tissue mobilization, multiple points of fixation, avoidance of hardware-related problems, and appropriate management of the capsule and bone defects...

Most Clostridium species are part of saprophytic microflora in humans and animals; however, some are well-known human pathogens. We presented the challenges in identifying the Clostridium species isolated from a patient with an infected open dislocation of the proximal interphalangeal joint of the fourth digit of the right hand. The clinical materials were intraoperative samples collected from a patient diagnosed with an injury-related infection, with soft tissue loss and tendon sheath involvement. The available biochemical, molecular, and genetic techniques were used in identifying the isolated bacteria...

INTRODUCTION: Medial canthus is a common area of skin cancer prevalence. Defects in this region represent a challenging reconstructive task. The nasal version of keystone perforator island flap (KPIF) has proven its versatility. The aim of the present study was to expand its utilization in the neighbor medial canthus area. A modified croissant-like KPIF (CKPIF) was used resolving inner convexity-related problems. The presence of procerus in the glabella area, bridging a surface from nasalis up to the frontalis, changed the traditional dissecting flap technique...

The newest impression techniques use intraoral scanners to capture both the hard and soft tissues. However, with edentulous patients, the accuracy of an intraoral scanner to capture an acceptable impression for the fabrication of a complete denture needs to be evaluated. Therefore, the purpose of this report of two patient treatments is to describe a technique that used intraoral scanning to record mucosal morphology and fabricate computer-aided design/computer-assisted manufacture (CAD/CAM) complete dentures...
