Background: Localized craniofacial scleroderma is a rare pediatric disease that involves a spectrum of discoloration, fibrosis and hemiatrophy of the face and scalp. Children with localized craniofacial scleroderma may have neurological symptoms, and in this context often undergo diagnostic imaging of the brain.
Objective: To catalogue neuroimaging abnormalities in patients with localized craniofacial scleroderma treated at our institution, review their clinical courses and compare this data with prior studies.
Materials And Methods: Following Institutional Review Board approval, an imaging database search identified 10 patients with localized craniofacial scleroderma and neuroimaging abnormalities treated at our institution. Neuroimaging exams and the electronic medical record were reviewed for each case.
Results: The most common indications for neuroimaging were headache or seizure (80% of cases). The most common neuroimaging abnormalities were T2-hyperintense, subcortical white matter lesions ipsilateral to the cutaneous lesion (90% of cases) on magnetic resonance imaging (MRI). Calcifications or blood products (50%), cysts (40%) and abnormal enhancement (20%) were also observed. A positron emission tomography (PET) scan obtained for a single case demonstrated diminished F-fluorodeoxyglucose (FDG) avidity corresponding to the dominant focus of signal abnormality on MRI. Progressive neuroimaging abnormalities were present in 30% of cases. There was no consistent relationship between changes in neurological symptoms following treatment and neuroimaging findings.
Conclusion: Our results are similar to previously published data. In the absence of new or worsening neurological symptoms, the role of neuroimaging for follow-up of localized craniofacial scleroderma is unclear. Knowledge of intracranial neuroimaging abnormalities that are commonly associated with localized craniofacial scleroderma helps to distinguish these lesions from others that have similar appearance.

Radiation therapy is widely recognized as an efficacious modality for treating neoplasms located within the craniofacial region. Nevertheless, this approach is not devoid of risks, predominantly concerning potential harm to the neural structures. Adverse effects may encompass focal cerebral necrosis, cognitive function compromise, cerebrovascular pathology, spinal cord injury, and detriment to the neural fibers constituting the brachial plexus.

Background: Sinonasal malignancies, in which squamous cell carcinomas are the most common are rare and difficult to treat given the location and anatomical structures involved. Sinonasal malignancies often present late due to non-specific and benign symptoms. Partial resections are often associated with poorer outcomes [1].

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome caused by hypersecretion of fibroblast growth factor 23 (FGF23) by typically benign phosphaturic mesenchymal tumors (PMTs). FGF23 excess causes chronic hypophosphatemia through renal phosphate losses and decreased production of 1,25-dihydroxy-vitamin-D. TIO presents with symptoms of chronic hypophosphatemia including fatigue, bone pain, weakness, and fractures.

Aims: Apical Periodontitis (AP) involves complex interactions between the root canal microbiome and the host immune response, with potential risk of local and systemic inflammatory burden, however there is no evidence available regarding correlation between microbiome and inflammatory marker levels. This study aims to identify the microbiome of saliva, intracanal and blood samples in AP subjects and investigate the correlation between intracanal and blood microbiomes with serum inflammatory biomarker levels, and salivary microbiomes with salivary inflammatory biomarker levels.
Methodology: Saliva, Intracanal and blood samples were collected from AP patients undergoing root canal retreatment.

Background: Fibrous dysplasia (FD) is a self-limiting benign disease with slow progression in which the normal bone is replaced by dysplastic fibrous tissue. The craniofacial skeleton is one of the most commonly affected areas, and it can create unique challenges in dental implant therapy. This case aims to report an unusual presentation of FD localized in the alveolar crest bone of the edentulous site, causing special obstacles to implant placement, and provide a diagnostic and treatment process that may be referenced.
