BACKGROUND: In the attempt to limit the post-surgery increase in buccal gingival recession (bREC), effect of a connective tissue graft (CTG) when combined with a buccal single flap approach (SFA) in the regenerative treatment of intraosseous defects is evaluated. METHODS: Data related to 30 patients with an intraosseous defect treated with a buccal SFA with (SFA+CTG group; n = 15) or without (SFA group; n = 15) placement of a CTG and regenerative treatment were retrospectively derived at three clinical centers...

BACKGROUND: The quantitative accuracy of MRI in predicting the intraosseous extent of primary sarcoma of bone has not been definitively confirmed, although MRI is widely accepted as an accurate tool to plan limb salvage resections. Because inaccuracies in MRI determination of tumor extent could affect the ability of a tumor surgeon to achieve negative margins and avoid local recurrence, we thought it important to assess the accuracy of MR-determined tumor extent to the actual extent observed pathologically from resected specimens in pediatric patients treated for primary sarcomas of bone...

BACKGROUND: In primary TKA, prophylaxis with low-dose vancomycin through intraosseous regional administration (IORA) achieves tissue concentrations six to 10 times higher than systemic administration and was shown to provide more effective prophylaxis in an animal model. However, in revision TKA, the presence of a tibial implant may compromise IORA injection, and tourniquet deflation during a prolonged procedure may lower tissue concentrations. QUESTIONS/PURPOSES: (1) Does low-dose IORA reliably provide equal or higher tissue concentrations of vancomycin compared with systemic IV administration in revision TKA? (2) Are tissue concentrations of vancomycin after IORA maintained for the duration of the revision TKA despite a period of tourniquet deflation? (3) Is there any difference in early postoperative (< 6 weeks) complications between IORA and systemic IV administration in revision TKA? METHODS: Twenty patients undergoing aseptic revision TKA were randomized to two groups...

Emphysematous osteomyelitis is a rare but potentially fatal infection. It is caused by gas-forming organismsand is characterized by the presence of intraosseous gas. A 75-year-old woman with untreated diabetes mellitus presented with difficulty in moving and anorexia. Laboratory studies revealed inflammation, a urinary infection, and diabetic ketoacidosis. Klebsiella pneumoniae was detected in both urine and blood cultures. Computed tomography and magnetic resonance imaging revealed emphysematous lesions in the paravertebral soft tissue, spinal canal, and iliopsoas muscle, with intraosseous gas at L1 and L2...

INTRODUCTION: In prior small animal studies, we maintained vascularized bone allotransplant viability without long-term immunotherapy. Instead, an autogenous neoangiogenic circulation is created from implanted vessels, sufficient to maintain bone viability with only 2 weeks immunosupression. Blood flow is maintained despite rejection of the allogeneic vascular pedicle thereafter. We have previously described a large animal (swine) pre-clinical model, reconstructing tibial defects with vascularized tibial allotransplants...

Successful treatment of deep intraosseous defects in esthetic areas implies clinical improvement of the lesion consistent with long-term tooth survival as well as the preservation (or improvement) of esthetics. It is hoped that such treatment end points may be reached through procedures (which we have termed as 'simplified') that, on the one hand can be easily and successfully applied by the majority of clinicians, and, on the other hand, are well tolerated by patients in terms of postsurgical pain and discomfort, adverse events and cost...

BACKGROUND: Blood transfusion through the intraosseous route is gaining popularity in emergency medicine. Pretransfusion peripheral blood (PB) samples are usually not available in these patients, leading to discrepancies in blood group typing and a possible delay in transferring to group-specific blood products. The aim of this study was to assess the feasibility of ABO and D typing and red blood cell alloantibody screening in marrow (BM) samples. STUDY DESIGN AND METHODS: Direct and reverse ABO typing, D typing, and a two-cell alloantibody screen were performed in EDTA-anticoagulated BM samples with standard manual column agglutination techniques...

INTRODUCTION: Aneurysmal bone cyst (ABC) is a benign intraosseous lesion filled with blood that can determine a blowout distension of the bone. The purpose of this study is to evaluate the efficacy of sclerotherapy by percutaneous intralesional administration of ethanol 96% for the treatment of this pathology in paediatric patients. METHOD: The retrospective study includes 17 paediatric patients with ABC who were treated by repeated intracystic injection with ethanol 96%, 1 ml/kg, in our clinic between December 2015 and July 2017...

Meningiomas account for a significant proportion of all primary intracranial tumors; distant metastasis is quite rare. We report a patient with resected, atypical meningioma. The patient's clinical course over 5 years included two craniotomies, a course of radiation, and a shortened course of bevacizumab. Only 5 months after starting bevacizumab, the patient developed an isolated left clavicular pathological fracture attributable to metastatic anaplastic meningioma. This constitutes the first report of meningioma with isolated extracranial intraosseous metastasis in the modern English literature and highlights concerns associated with the use of anti-angiogenic agents in promoting more invasive tumor phenotypes upon disease recurrence...

Oral cavity is not a usual site for metastasis, accounting about 1% of all oral tumors. The majority site for metastasis is the mandible and less common the maxilla followed by intraoral soft tissue. These tumors may be the first clinical manifestation of the primary lesion. One of the most important sites of the primary neoplasm that metastasizes to the jaws is kidney. Therefore, considering to this fact that the metastatic tumors always are not seen in a typical site, it is necessary to rule out the metastatic carcinomas to jaws...

Secreted osteoclastogenic factor of activated T cells (SOFAT) is a novel activated human T-cell-secreted cytokine that induce osteoclastogenesis in a RANKL-independent manner. The aim of this study was to evaluate the immunohistochemical expression of SOFAT in intraosseous and extraosseous lesions. Thirty-two oral biopsies were divided into 2 groups: (1) intraosseous lesions-4 cases of cherubism, 5 central giant cell lesions, 3 osteoblastomas, 3 cementoblastomas, 2 periapical lesions and (2) extraosseous lesions-5 peripheral giant cell lesions, 5 cases of oral paracoccidioidomycosis, and 5 foreign body reactions...

A 4-year-old girl presented repeatedly with a complicated occipital mass, which was erroneously treated as a pyogenic granuloma. Imaging performed before a planned surgical resection detected an underlying intraoccipital dermoid with a sinus tract to the skin surface and extension into the posterior fossa. This case highlights the value of high-resolution computed tomography imaging for depiction of anatomic details and the value of magnetic resonance imaging for differential diagnosis and surgical management...

INTRODUCTION: Intraosseous hemangiomas of the midface are rare with few reported cases in the literature. Various reconstructive methods have been previously described, but none using vascularized bone graft secondary to the benign nature of the tumor and often relatively limited defect size. CLINICAL REPORT: The authors present the case of a 47-year-old man with a biopsy proven enlarging right maxillary intraosseous cavernous hemangioma which was resected primarily, resulting in a large defect involving the entire zygomaticomaxillary buttress and a portion of the right orbital floor and malar prominence...

BACKGROUND: Positive-pressure exhaust suits cost more than standard surgical gowns, and recent evidence suggests that they do not decrease infection risk. As a result, some hospitals and surgeons have abandoned positive-pressure exhaust suits in favor of less expensive alternatives. We propose that in addition to their original purpose of decreasing infection rates, positive-pressure exhaust suits may also improve personal protection for the surgeon and assistants, perhaps justifying their added costs...

BACKGROUND: Intraosseous (IO) vascular access is increasingly used as an emergency tool for achieving access to the systemic circulation in critically ill patients. The role of IO transfusion of blood in Damage Control Resuscitation is however questionable due to possible inadequate flow rate and hemolysis. Some experts claim that IO transfusion is contraindicated. In this study we have challenged this statement by looking at flow rates of autologous fresh whole blood reinfusion and hemolysis using two of the commonly used FDA-approved and CE-marked sternal needles...

Temporary prosthesis transformed into a prosthetic prototypes and manufactured by CAD/CAM technologies (computer copy milling) are used to specify the final form of future permanent restoration and to correct occlusal relationships, vertical size of non-removable dentures, and their occlusal surfaces. A progressive loading on bone tissue in the implantation area and soft tissues formation, have been assessed. In this regard, the choice and placement of temporary mini-implants, as the supports for non-removable denture prototypes for the period of osseointegration of two-stage intraosseous dental implants, are the issues of great importance...
