Osteonecrosis of the ear canal in a patient treated with bisphosphonate.

In this case report, a 68-year-old woman, with known insulin-dependent diabetes and myelomatosis, presented with ear pain in her right ear. Otomicroscopy showed exposed bone in the external auditory canal. The patient was examined with wound swab, biopsies, MRI and PET-CT scans to rule out necrotizing external otitis, cholesteatoma and malignancy. Later, the patient's bisphosphonate treatment for myelomatosis was suspected, because osteonecrosis of the external auditory canal is a rare side effect to this treatment. The bone lesion improved after local debridement and cessation of the bisphosphonate treatment.

Second primary cancer following primary oral squamous cell carcinoma: a population-based, retrospective study.

BACKGROUND: Second primary cancer (SPC), defined as a metachronous solid cancer resulting from neither a recurrence of the primary cancer nor a metastasis, is a leading long-term cause of death for survivors of primary oral squamous cell carcinoma (OSCC). This study examined the risk of SPC following treatment of primary OSCC. MATERIALS AND METHODS: This semi-national, population-based, retrospective study included all patients with primary OSCC treated with curative intent in Eastern Denmark in 2000-2014. The presence of SPC was confirmed from medical records and the Danish Pathology Data Bank. The rate of SPC was compared to the occurrence of any cancer in the Eastern Danish population using data from the Danish Cancer Registry. RESULTS: A total of 936 patients with primary OSSC were enrolled. Of these, 219 patients (23%) were diagnosed with SPC during the follow-up (median 8.9 years, IQR: 5.4-12.6 years). The rate of SPC was four times higher than the occurrence of any cancer among the Eastern Danish population i.e., with a standardized incidence ratio (SIR) of 4.13 (95%CI: 3.55-4.80). SPCs were most frequently found in head and neck region (n = 97, SIR = 43.6), lower respiratory organs (n = 38, SIR = 5.6) and gastrointestinal organs (n = 33, SIR = 3.2) with increased SPC rates in all locations. Among patients who developed SPC within the study period the median time from OSCC to the first SPC was 4.4 years (IQR: 2.5-6.2). Significant associations were found between both smoking and excessive alcohol consumption after treatment of OSCC and the risk of SPC. CONCLUSIONS: A noteworthy increased rate of SPC following treatment of primary OSCC was found, especially in the head and neck region and in the lungs. Healthcare professionals should be aware of this increased risk.

Sequelae of Major Trauma Patients with Maxillofacial Fractures.

OBJECTIVES: Sequelae after maxillofacial fractures are frequent and may affect the patient's quality of life. This study examined sequelae associated with maxillofacial fractures of severely traumatized patients focusing mainly on nerve injuries. METHODS: A retrospective study including trauma patients with relevant facial fractures admitted to our Trauma Center in the period 2011-2016. Presence of posttraumatic maxillofacial sequelae was identified by examining the medical records of the included patients. Focusing on facial sensory deficits and facial nerve paralysis, but also comprising data on diplopia, blindness, malocclusion, trismus, eye globe malposition, flattening of the malar, facial contour changes, and wound infections. RESULTS: Two-hundred-seventy-five severely traumatized patients were included, comprising 201 men (73%), with a median age of 40 years and ISS of 20. 163 (59%) patients only had assessments within 3 months from trauma of which 79 patients (48.5%) had facial complications at initial examination, mostly malocclusion and trismus. Most patients in this group had no or only minor sequelae at their last clinical assessment, mainly being sensory deficits. 112 (41%) patients had assessments both within and beyond 3 months of which 73 patients (65.2%) had facial complications at initial examination, while 91 patients (81%) had reported sequelae within 3 months decreasing to 47 patients (42%) at their last clinical assessment beyond 3 months from trauma, mostly sensory deficits. An improvement of most sequelae was observed. CONCLUSION: Objective sequelae were found to be quite common after maxillofacial fractures in severely traumatized patients, especially sensory deficits. However, most of the addressed sequelae seemed to improve over time.
