Head and neck soft tissue sarcomas are a group of rare heterogeneous tumours arising from embryonic mesoderm. They comprise <1% of all head and neck malignancies and 5-15% of all sarcomas with most head and neck sarcomas arising from soft tissues. Although rare, they are associated with both high recurrence and mortality rates. We review the current management of head and neck soft tissue sarcomas.

Head and neck hard tissue sarcomas form a rare group of mesenchymal-derived tumours that comprise less than 1% of all head and neck neoplasms. Hard tissue sarcomas account for 20% of head and neck sarcomas and they form a heterogeneous group with a diverse origin. Unlike head and neck soft-tissue sarcomas, they have lower recurrence and mortality rates. In this study, we review the current management of head and neck hard tissue sarcomas.

Background Vertigo can have a negative impact on the quality of life of patients. Mobile health apps have the potential to promote autonomy, and improve symptoms through self-management and vestibular rehabilitation exercises. This study aimed to systematically evaluate the quality of apps for vertigo using the published literature and smartphone stores. Design A systematic review of the literature, utilising Embase, Medline, Cochrane and clinicaltrials.org, and Apple and Google Play Stores were used to identify mobile device apps relating to vertigo. Apps were evaluated for characteristics, content, healthcare involvement and quality using the Mobile App Rating Score (MARS) system (a standardised tool for assessing app quality). Results The literature search identified no eligible articles. The app search identified and evaluated 32 eligible apps. Four main categories of apps were identified: exercise provision, information provision, symptom monitoring and assessment. Six apps included healthcare professionals in their development. MARS scoring ranged between 1.8 and 4.05 (maximum 5), with only 25% of apps scoring the minimum acceptability score of 3. The highest scoring apps were those providing rehabilitation exercises and symptom monitoring. Conclusion There is great potential in the use of mobile apps to help monitor and manage vertigo. This article demonstrates that despite numerous readily available vertigo apps, few are of an acceptable standard. There is scope for apps to improve. We propose involving health professionals and patients in their development to ensure high quality evidence-based information and evaluating their efficacy through future patient-centred trials.
