Deep neck infections are potentially dangerous complications of upper respiratory tract or odontogenic infections. The pathophysiology, clinical presentation, and potential spreading depend on the complex anatomy of the neck fascia. These infections can lead to severe pathological conditions, such as mediastinitis, sepsis, and especially airway impairment with difficult management. Because of the risk of life-threatening emergency situations and the possible impacts on the overall health status of affected children, their early recognition is of utmost importance. Torticollis, drooling, and stridor are the most common signs of advancing disease. Children presenting with these symptoms should be admitted to the paediatric intensive care unit for vital function monitoring, where the airway could be readily secured if function is compromised.
Both denosumab (DNO) and bisphosphonates (BP), antiresorptive drugs (ARDs) used for the treatment of osteoporosis and oncological disorders, are known for their potential to cause medication-related osteonecrosis of the jaws (MRONJ). Besides ARDs, statins were recently associated with MRONJ development, especially in patients taking higher doses of statins for a longer period of time. Here, we report a case of a woman with osteoporosis who rapidly developed MRONJ stage III after only a single low dose of DNO. The patient was taking statins (rosuvastatin) for 7 years and had also been on BP (alendronate) for 4 years previously but this treatment was discontinued for approximately 1.5 years before MRONJ development. We performed a literature review of cases with MRONJ triggered by a single low dose of DNO and of cases with statin-induced MRONJ in patients not using ARD. Because the MRONJ development after a single low dose of DNO is rare, only eleven cases were previously described. We suggest that (i) in some patients, long-term use of statins and BP may lead to a higher susceptibility of MRONJ development after DNO exposure and (ii) that all predisposing factors to MRONJ development including the necessity of any dental procedures should be considered before DNO therapy is initiated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
