Conservative treatment of medication-related osteonecrosis of the jaw (mronj): report of 8 cases

The 8 cases selected for this presentation include medication-related osteonecrosis of the jaw (MRONJ) treated conservatively: 2 cases of breast cancer metastasis, 3 cases of multiple myeloma, and 3 cases of osteoporosis. Two of them occurred in the implant area and in 1 case, the treatment was concluded with hyperbaric oxygen therapy. In 5 cases, a bisphosphonate was given via intravenous route and 3 cases by oral administration. Only 1 case had a combination of bisphosphonates and monoclonal antibody (denosumab).

Shashkov, Nora M.A. Ponce, Carlos A. Stortz, Nikolay E. Nifantiev, Anatolii I. UsovAbstractFucosylated chondroitin sulfate (FCS) HeSp was isolated from the Patagonian sea cucumber Hemioedema spectabilis. Ion-exchange chromatography was applied for purification of the FCS from the crude extract of sulfated polysaccharides. Analysis of monosaccharide and sulfate content of HeSp revealed the molar ratio of GlcA:GalNAc:Fuc:SO3Na as 1.15:1:1.1:3.9. Molecular weight...

Cancer immune evasion is achieved through multiple layers of immune tolerance mechanisms including immune editing, recruitment of tolerogenic immune cells, and secretion of immunosuppressive cytokines. Recent success with immune checkpoint inhibitors in cancer immunotherapy suggests a dysfunctional immune synapse as a pivotal tolerogenic mechanism. Tumor cells express immune synapse proteins to suppress the immune system, which is often modulated by epigenetic mechanisms. When the methylation status of key immune synapse genes was interrogated, we observed disproportionately hypermethylated costimulatory genes and hypometh...

Increased rates of locoregional recurrence are observed in patients with basal-like breast cancer (BC) despite the use of radiation therapy (RT); therefore, approaches that result in radiosensitization of basal-like BC are critically needed. Using patients’ tumor gene expression data from 4 independent data sets, we correlated gene expression with recurrence to find genes significantly correlated with early recurrence after RT. The highest-ranked gene, TTK, was most highly expressed in basal-like BC across multiple data sets. Inhibition of TTK by both genetic and pharmacologic methods enhanced radiosensitivity in mul...

Tumor cells are in an adhesion profile during cell-cell and cell-matrix interaction. However, it is challenging for current platforms (e.g., typical droplet systems) to measure MMP9 secreted by single cells in an adhesion profile and retrieve the cells of interest for downstream analysis. Herein, we report a single-cell protease sensor (SCPS) based on ‘...

In this study, protein-based nanoparticles were constructed with TRAIL and a dipeptide, diphenylalanine (FF), through molecular self-assembly. TRAIL-FF nanoparticles with sizes ranging from 60 nm to 500 nm could be prepared by controlling the concentration and the ratio of the two components. These nanoparticles could locate around the cytomembrane of MCF-7 cells due to the specific interaction between TRAIL and death receptors, thus transduce apoptotic signal. Therefore, the TRAIL-FF nanoparticles showed distinct killing effect on the cancer cells, such as MCF-7 and H460 cells, and the IC50 of the nanopartic...

Conclusion and Perspectives The IL-6/JAK/STAT signaling cascade plays a dominant role in skeletal muscle pathophysiology. IL-6 autocrine, paracrine, and endocrine functions assign to its downstream effectors pivotal importance in skeletal muscle-wasting-associated diseases and other multiple system diseases where muscle acts in communication with other organs. Targeting the components of the JAK/STAT pathway recently emerged as a strategic approach for the treatment of inflammatory diseases and human cancer. This review highlights the opposite outcomes on muscle biology caused by the amount of local and systemic release ...

Conclusiones: El tratamiento de la OMAM depende del estadio de la enfermedad; la mandibulectomía es un tratamiento efectivo en el estadio 3 y la secuestrectomía en el estadio 2; el estadio 1 suele controlarse con tratamiento conservador.ABSTRACT Introduction: Bisphosphonates are a family of drugs used to inhibit bone resorption. One of their secondary effects is osteonecrosis of the jaws (ONJ). In 2010, scientists began to publish cases of osteonecrosis of the jaws associated with a new drug, denosumab. In 2014 it was recommended to change the name of ONJ to medication-related osteonecrosis of the jaws (MONJ)...

Authors: Bagan L, Jiménez Y, Leopoldo M, Murillo-Cortes J, Bagan J Abstract BACKGROUND: The main objective of our study was to identify oral symptoms and signs most likely to be associated with the exposure of necrotic bone in bisphosphonate-related osteonecrosis of the jaw (BRONJ). MATERIAL AND METHODS: The study group consisted of 183 patients with BRONJ. We recorded data on the underlying disease, bisphosphonate used, location of osteonecrosis, symptoms, pain, fistula development, suppuration, infection, exposed necrotic bone, and BRONJ stage. RESULTS: The mean age of the patients was 68.22 &plusm...

Skeletal metastases are an incurable complication afflicting the majority of patients who die from advanced breast cancer. They are most often osteolytic, characterized by net bone destruction and suppressed new bone formation. Life expectancy from first diagnosis of breast cancer bone metastases is several years, during which time skeletal-related events - including pain, fracture, hypercalcemia, and spinal cord compression - significantly degrade quality of life. The bone marrow niche can also confer hormonal and chemo-resistance. Most treatments for skeletal metastases target bone-destroying osteoclasts and are palliati...
