Prolonged Hypophosphatemia and Intensive Care After Curative Surgery of Tumor Induced Osteomalacia: A Case Report.

Front Endocrinol (Lausanne) 2021 3;12:686135. Epub 2021 Jun 3.

Endocrinology, Abdominal Center, Helsinki University Hospital and University of Helsinki, Helsinki, Finland.

Introduction: Rare FGF23-producing mesenchymal tumors lead to paraneoplastic tumor-induced osteomalacia (TIO) presenting with phosphate wasting, hypophosphatemia, chronic hypomineralization of the bone, fragility fractures and muscle weakness. Diagnosis of TIO requires exclusion of other etiologies and careful search for a mesenchymal tumor that often is very small and can appear anywhere in the body. Surgical removal of the tumor is the only definitive treatment of TIO. Read More

A new classification of mandibular fractures.

Int J Oral Maxillofac Surg 2021 Jun 3. Epub 2021 Jun 3.

Liverpool Head and Neck Centre, Aintree University Hospital NHS Foundation Trust, Liverpool, UK.

There is no accepted method of reporting mandibular fracture that reflects incidence, treatment and outcome for individual cases. As most series include anatomical site only for all fractures, the aim was to establish a new method to report fractures based on a systematic review of the literature and an internal audit. The classification proposed is: Class I; condyle, II; angle, IIc; II+condyle, III; body/symphysis, IIIc; III+condyle, IV; multiple fractures not including condyle, IVc; IV+condyle, V; bilateral condyle±other fracture(s).

Volumetric Evaluated Bone Resorption After Open Reduction and Internal Fixation of Condylar Head Fractures of the Mandible.

J Oral Maxillofac Surg 2021 Apr 23. Epub 2021 Apr 23.

Senior physician, Department of Craniomaxillofacial Surgery, University Hospital Zürich, Switzerland.

Purpose: Decision making in the management of condylar head fractures remains difficult due to its dependency on multiple factors like fracture type, degree of dislocation, patient`s age and dental condition. As open reduction and internal fixation (ORIF) of condylar head fractures (CHFs) becomes more popular, the question of osteosynthesis removal is controversial. So far, information on volumetric changes after ORIF are available for a short-term period (<6 months) only. Read More
