Rappresentazioni vertiginose. Tre esempi: Perec, Lequeu, Douat
2022
Nel novembre del 2009 il Museo del Louvre decise di affidare a Umberto Eco la direzione di una serie di conferenze da tenere su un argomento di sua scelta. Eco scelse il tema della ‘lista’ conferendo a quella manifestazione il nome di Vertige de la liste a cui seguì un saggio dallo stesso titolo pubblicato da Bompiani. Questa breve nota prende in prestito la stessa tematica che, per via del suo carattere altamente ete-rogeneo, è in grado di coinvolgere diversi ambiti del sapere senza minimamente accennare ad esaurirsi. L’elenco, strettamente legato alla figura retorica dell’accumulazione, può infatti costituirsi di segni, parole, suoni e di qualsiasi altra forma di rappresentazione utile a …
Vertigo in childhood: A methodological approach
2012
Children complaints dizziness merit meticulous evaluation to differentially diagnose a vestibular disease. A syndrome mimicking certain classic signs and symptoms of adult vestibular disorders may be presents in children, such as benign paroxysmal positional vertigo, usually associated with aging. Benign paroxysmal vertigo, in which migraine is a manifestation, with sudden onset of dizziness is a rare peripheral vestibular disorder that is commonly ignored or misdiagnosed. This review covers the development of the diagnosis, evaluation and treatment approaches of vertigo of childhood, a valid support for physician that approach dizzy children (Ref. 25).

Vertigo and osteoporosis: The correlation between nutritional intake of Vitamin D and incidence of recurring benign paroxysmal positional vertigo in …
2018
Introduction: Benign paroxysmal positional vertigo (BPPV) is the most common peripheral cause of vertigo. It can be defined as transient vertigo induced by rapid changes in head position associated with a characteristic paroxysmal positional nystagmus. The aim of this study is to evaluate the association between the serum calcium and Vitamin D levels in osteoporotic patients affected by recurrent BPPV. Materials and Methods: Calcium and 25-hydroxy-Vitamin D levels were evaluated in peripheral venous serum samples of 40 BPPV patients. Results: The reduction of serum Vitamin D levels is present in 16 of BPPV patients with recurrence. After nutritional intake of Vitamin D there was a decline o…

Canal switch and re-entry phenomenon in benign paroxysmal positional vertigo: difference between immediate and delayed occurrence
2014
Studio prospettico ideato per la valutazione delle differenze tra la conversione canalare o il rientro degli otoliti nei canali semicircolari successivo alle manovre terapeutiche nei pazienti affetti da VPPB. Sono stati valutati 196 pazienti affetti da VPPB, 127 dei quali corrispondevano ai criteri di inclusione. L’età media dei pazienti era di 54.74 anni. Il canale orizzontale è stato coinvolto in 30 casi e il canale posteriore in 97 pazienti. I pazienti con sordità neurosensoriale presentavano forme ricorrenti di VPPB, rispetto a quelli con udito normale. L’immediato rientro canalare è stato diagnosticato in 3 pazienti con VPPB del canale laterale, tutti con nistagmo geotropo. 7 pazienti …
Observational study on risk factors determining residual dizziness after successful benign paroxysmal positional vertigo treatment: The role of subcl…
2018
Studio osservazionale sui fattori di rischio che causano residual dizziness dopo il trattamento della vertigine parossistica posizionale benigna: il ruolo della VPPB subclinica.Alcuni pazienti, dopo il trattamento della vertigine parossistica posizionale benigna concluso con successo, possono lamentare un disequilibrio residuo. La possibile spiegazione potrebbe essere: la persistenza di otoliti canalari insufficienti a provocare un nistagmo clinicamente evidente, una disfunzione utriculare, coesistenza di altri disordini del sistema vestibolare. Abbiamo condotto uno studio osservazionale prospettico caso-controllo, focalizzando l’attenzione sul ruolo di fattori di rischio che possono causar…
Sudden sensorineural hearing loss associated with inner ear lesions detected by magnetic resonance imaging.
2017
Although recent advances in magnetic resonance imaging (MRI) techniques have contributed to the detection of tiny lesions in the internal auditory canal (IAC) that may be responsible for sudden sensorineural hearing loss (SSNHL), there have been relatively few studies on the clinical characteristics of intra-labyrinthine hemorrhage (ILH) and labyrinthitis versus those regarding IAC tumors. Our purpose was to investigate the frequency of those IAC lesions on MRI and their clinical characteristics. Initial MRIs of 200 patients with SSNHL (93 men, 107 women; mean age = 48.61 years, range: 18-84 years), as well as detailed clinical histories, audiological examinations, and thyroid function, lip…
MENIERE’S DISEASE & NEUROVASCULAR CROSS-COMPRESSION: CASE REPORT
2009
Meniere’s disease is typically characterized by the classic symptomatological triad consisting of vertigo associated with nausea and vomiting, fluctuating but progressive hearing loss, and tinnitus. The main pathophysiological substrate of Meniere's disease is certainly endolymphatic hydrops, the etiology of which is probably multifactorial, but still not completely understood. Recently, it has been shown that vertigo, hearing loss, and tinnitus can be the result of a vascular loop impinging on the VIIIth nerve and giving rise to the symptomatological complex that can been defined as Meniere's disease due to ‘cochleovestibular nerve compression syndrome’ (CNCS). In this cases the surgical t…
A multicenter observational study on the role of comorbidities in the recurrent episodes of benign paroxysmal positional vertigo
2014
Objective: Primary objective of this study was to find a statistical link between the most worldwide comorbidities affecting the elderly population (hypertension, diabetes, osteoarthrosis, osteoporosis and depression) and recurrent episodes of BPPV. Secondary objective was defining possible "groups of risk" for people suffering recurrent positional vertigo related to the presence of a well documented comorbidity. Methods: This was an observational, cross-sectional, multicenter, spontaneous, non-pharmacological study. The data of 1092 patients suffering BPPV evaluated in 11 different Departments of Otolaryngology, Otoneurology and Neurology, referring Centers for positional vertigo evaluatio…
Positional vertigo afterwards maxillary dental implant surgery with bone regeneration
2007
Benign paroxysmal positional vertigo (BPPV) is the most common form of vertigo. It is caused by loose otoconia from the utricle which, in certain positions, displaced the cupula of the posterior semicircular canal. BPPV most often is a result of aging. It also can occur after a blow to the head. Less common causes include a prolonged positioning on the back (supine) during some surgical procedures. Additionally one can include in this ethiopathogenesis the positioning required during the maxillary dental implant surgery with bone regeneration related to a forced head positioning and inner ear trauma induced by dental turbine noise working in the maxillary bone. Two cases of patients who suf…
