A Retrospective Observational Study of Risk Factors for Denosumab-Related Osteonecrosis of the Jaw in Patients with Bone Metastases from Solid Cancers.

This single-center retrospective observational study aimed to identify risk factors for developing denosumab-related osteonecrosis of the jaw (DRONJ) in stage IV solid cancer patients with bone metastases. In total, 123 consecutive patients who had received 120 mg of denosumab every 4 weeks at least twice between July 2014 and October 2018 were included. We surveyed their demographics, medical history, blood test, underlying disease, and intraoral findings. Fourteen patients (11.4%) developed DRONJ within a mean denosumab administration period of 4 months (range: 2-52 months). Univariate analy

Management of Medication-Related Osteonecrosis of the Jaws With Hyperbaric Oxygen Therapy: A Case Report.

Medication-related osteonecrosis of the jaw (MRONJ) refers to the condition where the maxillary or mandibular bone becomes exposed and necrotic as a result of bisphosphonate therapy. The number of patients on bisphosphonates is increasing and so are the MRONJ cases. Since the initial data were published in the early 2000s, research into MRONJ has expanded significantly to enhance the understanding of this emerging condition. Various treatment options are available, but none have been established as the definitive "gold standard" for managing this disease. Hyperbaric oxygen therapy (HOT) is one

Drug holiday of high-dose denosumab and recovery from osteoclast inhibition using immunohistochemical investigation of 7 patients with medication-related osteonecrosis of the jaw undergoing segmental mandibulectomy.

BACKGROUND/PURPOSE: Denosumab is used to treat bone metastases from malignant tumors. Unlike bisphosphonates, denosumab is not deposited in the bone; thus, withdrawal for a relatively short period would help recovery from osteoclast suppression. This study investigated the relationship between drug holidays and recovery from osteoclast suppression. MATERIALS AND METHODS: Seven patients who received high-dose denosumab and underwent segmental mandibulectomy for medication-related osteonecrosis of the jaw were enrolled in this study. Osteoclast suppression (+) was defined as the absence of cath

Osteoporosis Drug Treatment Update.

The Brazilian population is aging and the prevalence of chronic degenerative diseases, including osteoporosis, is increasing. The diagnosis and treatment of osteoporosis have made significant advances in the last decade. The orthopedist and traumatologist can no longer be detained only in the surgical treatment of osteoporotic fracture. It is extremely important that we know: 1) what risk factors to evaluate, and the Fracture Risk Assesment Tool (FRAX) can be used; 2) which complementary tests should be requested, such as densitometry, radiography of the spine and pelvis, blood and urine tests

An unusual presentation of metastatic prostate cancer in a 44-year-old man: A case report and review of the literature.

UNLABELLED: Prostate cancer is one of the two most common non-cutaneous cancers in men. Its presentation might be with unusual symptoms and cause the wrong initial diagnosis. This case report discusses a rare neurologic manifestation of advanced metastatic cancer in a low-risk man. He had been receiving treatment for multiple sclerosis incorrectly due to unusual manifestations such as claudication and pelvic, leg, and shoulder pain. The patient underwent a whole-body bone scan and then a transrectal ultrasound-guided biopsy, which confirmed metastatic prostate cancer with a Gleason score betwe

Osteolytic Lesion of the Maxilla in an Undiagnosed Multiple Myeloma Patient Identified Incidentally by Cone Beam Computed Tomography.

BACKGROUND Multiple myeloma is a hematological malignancy characterized by monoclonal plasma cell proliferation. Jaw lesions are found in nearly 35% of patients with symptomatic myeloma, and lesions occur in the mandible more often than in the maxilla. However, maxillary or mandibular lesions are rarely found as a primary manifestation of the disease. This report describes a case of a 65-year-old Palestinian woman with lytic lesions in the maxilla due to undiagnosed multiple myeloma identified incidentally on cone beam computed tomography (CBCT). CASE REPORT A 65-year-old Palestinian woman pre

Treatment of central giant cell lesions using bisphosphonates with intralesional corticosteroid injections.

Central giant cell lesions are benign intraosseous proliferative lesions that have considerable local aggressiveness. Nonsurgical treatment methods, such as intralesional corticosteroid injections, systemic calcitonin and interferon have been reported. Recently, bisphosphonates have been used to treat central giant cell lesions. A case of a 36-year-old male with a central giant cell lesion crossing the mandibular midline was treated with intralesional corticosteroids combined with alendronate sodium for the control of systemic bone resorption. The steroid injections and the use of bisphosphona

A retrospective study on the incidence of medication-related osteonecrosis of the jaws (MRONJ) associated with different preventive dental care modalities.

PURPOSE: To assess the efficacy of different preventive dental visits and treatments in reducing the risk of medication-related osteonecrosis of the jaws (MRONJ). METHODS: In this retrospective study, patients diagnosed with MRONJ were divided into 5 groups based on available data: no preventive dental visits (group 0); dental visits and compliance with recommended treatments, at the university hospital's dental clinic (group 1) or maxillofacial surgery unit (group 2), or at a private dentist's (group 3); dental visits at one of the above and noncompliance with proposed treatments (group 4);

Could Local Application of Hypoxia Inducible Factor 1-α Enhancer Deferoxamine Be Promising for Preventing of Medication-Related Osteonecrosis of the Jaw?

This experimental study investigates the prophylactic effect of deferoxamine (DFO) on medication-related osteonecrosis of the jaw (MRONJ). Thirty-six female Sprague Dawley rats received zoledronic acid (ZA) for eight weeks to create an osteonecrosis model. DFO was locally applied into the extraction sockets with gelatin sponge (GS) carriers to prevent MRONJ. The specimens were histopathologically and histomorphometrically evaluated.
