"Intraosseous"

Ramon syndrome (OMIM #266270) was first described in a patient with cherubism, gingival fibromatosis, epilepsy, intellectual disability, hypertrichosis, and stunted growth. In 2018, Mehawej et al. described a patient with Ramon syndrome in whom a homozygous variant in ELMO2 was identified, suggesting that this gene may be the causative for this syndrome. ELMO2 biallelic pathogenic variants were also described in patients with a primary intraosseous vascular malformation (PIVM; OMIM #606893). These patients presented gingival bleeding and cherubism phenotype...

A man in his 40s presented with an incidental finding of an osteolytic bone lesion. He sustained an ankle injury while inline skating, fracturing his lateral malleolus. Besides the fracture, radiographic imaging on the day of the injury incidentally revealed a well-defined solitary osteolytic lesion with a sclerotic rim within the right calcaneus. MRI showed an intraosseous, fat-containing lesion with focal contrast enhancement, assessed as an intraosseous lipoma with central necrosis. In the pathological analysis of a sample of the lesion an intraosseous myo lipoma of the calcaneus was found-an unexpected and extraordinary finding...

OBJECTIVES: Giant cell granuloma is a local nonneoplastic lesion that is divided into two categories, based on its site of occurrence: Central and peripheral giant cell granuloma. Central giant cell granuloma is an intraosseous lesion that has a tendency to recure even in surgically treated cases. Several studies have proven that there is an association between different lesions clinical behavior and their histological features. The aim of this study was to evaluate the expression of AgNOR and Ki67 in lesions with and without recurrency...

Intraosseous vascular pathology of the turbinates is extremely rare in the practice of an otorhinolaryngologist and can be presented in various histopathological variants. The article presents two clinical cases in which an intraosseous cavernous hemangioma was hidden under the mask of a hypertrophied middle turbinate. The final diagnosis was established by the results of histological examination. The analysis of these clinical cases indicates that, despite the low prevalence, atypical clinical and CT picture, intraosseous formations of the nasal cavity can be of a vascular nature and certainly require a comprehensive examination, including CT, CT with contrast and/or MRI of the nose and paranasal sinuses...

INTRODUCTION: Pediatric trauma resuscitations are low-frequency, high-stakes events that require skilled multidisciplinary teams with strong medical knowledge and communication skills. METHODS: This pediatric trauma simulation training session included two cases and formats. The first case was designed in a traditional format and featured a 12-month-old child with inflicted blunt head and abdominal trauma. The second case was organized in successive rounds utilizing the rapid cycle deliberate practice (RCDP) model and featured an 18-month-old with gunshot wounds to the abdomen and chest...

BACKGROUND: Intraosseous xanthomas are rare benign lesions sometimes associated with excess lipid production. Xanthoma of the jaw bones (XJB) was first reported in 1964, and fewer than 50 cases have been reported in the English literature to date. The etiopathogenesis of XJB is highly suggestive of a reactive process or a metabolic condition. METHOD: Seven cases of XJBs were retrieved from the archives of 4 oral and maxillofacial pathology services. Clinical, radiographic and histopathologic features of all these cases were retrospectively analyzed...

Rhabdomyosarcoma is a highly malignant tumor with striated muscle differentiation, which is histologically classified as alveolar, embryonal, pleomorphic, and spindle cell/sclerosing histological subtype. Rhabdomyosarcoma with TFCP2 rearrangement, which usually occurs in the bone, is a newly identified rare spindle and epithelioid rhabdomyosarcoma with characteristic clinicopathological features and molecular alterations. We report a 39-year-old female patient who underwent local excision of the mandibular lesion...

BACKGROUND: Dysphagia, or swallowing dysfunction, is a commonly observed complication among stroke patients, which has been associated with increased mortality rates. The treatment of post-stroke dysphagia encompasses various therapeutic approaches, and Kinesio taping has recently emerged as a potentially effective intervention. This study aims to evaluate the potential benefits of Kinesio Tape in improving dysphagia symptoms in individuals who have experienced a stroke. METHODS: his study searched PubMed, Embase, The Cochrane Library, Web of Science, Wanfang Medical Database, CBM, CNKI, and Wipro VIP databases...

CASE: We will present the case of a 6-year-old girl who presented with a 3-cm limb length discrepancy after intraosseous line placement at age 14 months without other known history of trauma or infection to account for the growth arrest. Imaging revealed a left proximal tibial physeal bar amenable to surgical resection with autologous lipotransfer. At 10 months postoperatively, physical examination and imaging demonstrated a stable 3-cm leg length discrepancy with an interval increase in the length of the left tibia in proportion to the growth of the right side with an increase in valgus alignment that will continue to be monitored and addressed as indicated...

HYPOTHESIS: Development of a new method for large vestibular aqueduct (LVA)/large endolymphatic sac anomaly (LESA) assessment using magnetic resonance imaging (MRI) and computed tomography (CT)/cone beam CT (CBCT) images. The secondary objective was to compare both modalities. BACKGROUND: The gold standard for LVA diagnosis is the analysis of CT images using Valvassori and Clemis or Cincinnati criteria. The previous studies showed inconclusive results regarding the correlation between audiological and radiological data...

BACKGROUND: Fibrous dysplasia (FD) is a benign developmental disorder of the bone that causes normal skeletal tissue to be replaced by excess fibrous tissue and poorly differentiated osteoblasts. Intraosseous xanthomas are benign intraosseous tumor growths characterized microscopically by the presence of lipid-laden foamy histiocytes, often with cortical expansion or disruption. Although FD commonly occurs in craniofacial bones, primary intraosseous xanthomas of the skull or facial skeleton are extremely rare...

Introduction Early postoperative pain poses a challenge for surgeons to manage after total knee arthroplasty (TKA). Various techniques have been employed to optimize pain reduction, including Periarticular Multimodal Analgesia (PMA), recognized as a safe and effective method. Our study aims to enhance PMA through a combined intraosseous injection (PMA-I) and compare it with standard PMA. Methods Forty patients undergoing simultaneous bilateral TKA surgery were enrolled. Patients were randomized to receive PMA-I on one side of the knee, while the contralateral knee received standard PMA...

INTRODUCTION: Intraosseous (IO) administration of vancomycin at the time of total knee arthroplasty (TKA) has been shown to be safer and more effective than intravenous (IV) administration at preventing early periprosthetic joint infection. Previous studies have relied on tourniquet inflation to enhance local tissue concentrations and mitigate systemic release. METHODS: A single-blinded, randomized clinical trial was performed on 20 patients (10 IV, 10 IO) undergoing primary TKA...

OBJECTIVE: The aim of this study was to demonstrate the feasibility of diagnosing osteoporosis through routine computed tomography (CT) by assessing the association between the histopathological assessment of femoral head specimens extracted from patients who underwent surgery for intertrochanteric fractures and the Hounsfield unit (HU) measurements derived from preoperative CT scans. METHODS: Forty-eight patients who presented to our clinic between November 2019 and May 2020 with hip fractures and underwent partial prosthesis fixation were included in this retrospective study...

BACKGROUND: Improving oxygenation and ventilation in drowning patients early in the field is critical and may be lifesaving. The critical care interventions performed by physicians in drowning management are poorly described. The aim was to describe patient characteristics and critical care interventions with 30-day mortality as the primary outcome in drowning patients treated by the Danish Air Ambulance. METHODS: This retrospective cohort study with 30-day follow-up identified drowning patients treated by the Danish Air Ambulance from January 1, 2016, through December 31, 2021...

A 59-year-old woman presented to our clinic with a 3.5× 3-cm protruding mass on her forehead. A skull X-ray revealed a radiolucent osteolytic lesion on the left side of the frontal bone. Additionally, computed tomography showed a 3.1× 1.7× 3.6-cm mass exhibiting a "sunburst" pattern situated between the outer and inner tables of the skull, just superior and lateral to the left frontal sinus. This pattern suggested the presence of an intraosseous vascular malformation (IVM). The lesion was approached via a bicoronal incision...

Cellular therapies provide promising options for inducing tolerance in transplantation of solid organs, bone marrow, and vascularized composite allografts. However, novel tolerance-inducing protocols remain limited despite extensive research. We previously introduced and characterized a Human Multi-Chimeric Cell (HMCC) line, created through ex vivo fusion of human umbilical cord blood (UCB) cells derived from three unrelated donors. In this study, we assessed in vivo biodistribution and safety of HMCC in the NOD...

IntroductionShock is circulatory insufficiency, inadequate oxygen delivery, and cellular hypoxia. Intravenous fluids are essential for shock management. Despite treatment, patients can face persistent shock with ongoing hypotension, contributing to higher mortality. This analysis aims to quantify hypotensive non-traumatic cases in an Australian ambulance service, determine persistent hypotension prevalence, and assess paramedic-administered intravascular fluids' impact on blood pressure changes.MethodsThis study is a retrospective analysis of prehospital fluid resuscitation by New South Wales Ambulance paramedics during 2022...

Mucoepidermoid carcinoma is a rare neoplasm of the salivary gland of which the intraosseous variety is commonly observed with a female predilection and the affected side is more commonly in the mandible. It is usually perceived as an asymptomatic swelling that increases in volume over a few months to a year. They more frequently present as a cortical bulging and are mostly discovered as an accidental finding in a routine radiograph as a well-defined unilocular or multilocular radiolucency resembling an odontogenic cyst...

INTRODUCTION: Intraosseous ganglion cysts are an uncommon variant found in the subchondral bone. We report here the development of an intraosseous ganglion cyst of the proximal tibia in the setting of a prior left total knee arthroplasty (TKA) with an all-polyethylene tibial component. CASE REPORT: The cyst was diagnosed on routine follow-up radiographs approximately 4 years status post-TKA. Although initially asymptomatic, 1 year later the patient presented with progressive knee pain and ambulation limitations, so revision TKA was indicated...
