Age-related features in vestibular migraine onset: A multiparametric analysis.

BACKGROUND: Clinical heterogeneity is a peculiarity of vestibular migraine, in contrast to other vestibular disorders that have a more stereotypical expression. Migraine presents a range of variability in symptoms depending on the age of the patient. Supposing that migraine headache and vestibular migraine share the same pathogenetic mechanisms, a multiparametric analysis was performed to verify the hypotheses of an age-related influence on the clinical features of vestibular migraine at the onset. METHODS: In this retrospective study, we analysed the clinical records of 72 consecutive patients affected by vestibular migraine from June 2012 to November 2018: 64 females and eight males; mean age 38.2 ± 9.6. We considered only patients that reported onset of vestibular symptoms within 12 months preceding inclusion into the study. RESULTS: Statistical analysis shows a significant increase in the diagnosis of probable vestibular migraine with increasing age and a decrease in vestibular migraine diagnosis (p = 0.034). The incidence of spontaneous dizziness increases with age (p = 0.012); by contrast, external spontaneous vertigo, and visually induced vertigo decrease after 40 years of age (p = 0.018), clinically characterising the onset of juvenile forms. Spontaneous vertigo, head motion-induced vertigo/dizziness, and positional vertigo did not show significant variations with age. CONCLUSION: Our data show that the type of vestibular symptoms in vestibular migraine varies according to the age of onset.

Second primary carcinoma arising on a flap: a new primary or a relapse?

BACKGROUND AND AIM: Free flaps or pedicle flaps are the mainstay of cancer surgery in the head and neck area. However, their long-term sequelae are still poorly understood. Among these, the development of a secondary primary tumor on a flap is a rare and uncertain reported event.   Methods: A computer-aided systematic literature search was performed by using the PubMed, EMBASE and Cochrane Library databases. A systematic review of the literature, following the PRISMA checklist, was carried out with the aim of analyzing all the citations reporting this second primary, with attention to risk factors, behavior, etiological causes.   Results: Overall, 27 cases of second primary squamous cell carcinoma arising on a pedicle or free flap were identified. In addition, other three cases were discussed.   Conclusions: Persistent exposure to oral stimuli such saliva, oral microbiome, smoke or a colonization by the adjacent mucosa were considered as a possible cause of second primary carcinoma. Although rare, a new neoplasm onset should know and considered as a new concept in the follow-up of patients undergoing reconstruction with free or pedicle flaps.
