Ability of short-time Fourier transform method to detect transient changes in vagal effects on hearts: a pharmacological blocking study.

2006

Conventional spectral analyses of heart rate variability (HRV) have been limited to stationary signals and have not allowed the obtainment of information during transient autonomic cardiac responses. In the present study, we evaluated the ability of the short-time Fourier transform (STFT) method to detect transient changes in vagal effects on the heart. We derived high-frequency power (HFP, 0.20–0.40 Hz) as a function of time during active orthostatic task (AOT) from the sitting to standing posture before and after selective vagal (atropine sulfate 0.04 mg/kg) and sympathetic (metoprolol 0.20 mg/kg) blockades. The HFP minimum point during the first 30 s after standing up was calculated and…

Dizziness and vertigo in a department of emergency medicine.

1995

Dizziness is a common and vexing diagnostic problem in emergency departments. The term is rather undefinite and often misused, but can in practice be classified into four categories: fainting, disequilibrium, vertigo and miscellaneous syndromes. Vertigo is the most common category of dizziness. Classification of vertigo can be based either on chronological criteria (acute, recurrent or chronic vertigo) or on topographical criteria (peripheral or central vertigo). Physicians working in emergency departments must be able to rapidly identify patients with potentially serious forms of vertigo, which could cause death or disability, and patients with mild conditions, that can be effectively trea…

Treatment with a new nutraceutical compound on patients suffering from balance disorders: Dizziness handicap inventory scores

2019

Objective: Purpose: To investigate whether treatment with citicoline, in association with vitamin B6, ginger, melissa and ViNitrox, could improve Dizziness Handicap Inventory (DHI) scores in patients affected by dizziness and vertigo. Materials and methods: Fifty-five consecutive subjects (ranging from 49 to 71 years of age) who complained of dizziness and vertigo of unknown origins were treated with citicoline (500 mg) along with ginger (200 mg), vitamin B6 (2.1 mg), melissa (300 mg) and ViNitrox (150 mg) twice per day for a two-month period. Patients underwent pure tone audiometry (PTA) and a neurotological visit including spontaneous nystagmus testing, bedside examination and the Romberg…

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).

Diagnostic Role of Combined Electrocochleography and Pure-Tone Audiometry Monitoring During Dehydrating Test in Ménière's Disease: A Case Series

2023

Objectives: To evaluate the diagnostic role of combined electrocochleography and pure-tone audiometry monitoring during dehydrating test in Ménière's disease and consider its suitability as a diagnostic tool to differentiate those patients with unclear differential diagnosis and therefore identify those with clear endolymphatic hydrops responsive to dehydrating test. To study the efficacy of dehydrating therapy on vertiginous symptoms and hearing loss in patients with Ménière's disease. Study design: Prospective case series. Settings: University hospital, secondary referral center. Patients: Thirty patients, 20 women and 10 men, age range of 25 to 75 years, matching the criteria for definit…

Determinants of patient and health system delay among Italian and foreign-born patients with pulmonary tuberculosis: a multicentre cross-sectional st…

2018

ObjectivesThe aim of this cross-sectional study was to identify key factors associated with patient delay (PD), health system delay (HSD) and total delay (TOTD) in patients with tuberculosis (TB) to inform control programmes.SettingThe study was conducted in four Italian regions in 2014–2016. Data were obtained using a questionnaire including: sociodemographic and lifestyle data, TB comorbidities, patient knowledge and attitudes towards TB, stigma, access to TB care and health-seeking behaviours.ParticipantsPatients’ inclusion criteria were being diagnosed as a new smear positive pulmonary TB case and living in one of the participating Italian regions. Overall, 344 patients from 30 healthca…

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 …

The role of emotion awareness and mood: somatic complaints and social adjustment in late childhood.

2014

Emotion awareness is a key concept related to different child adjustment outcomes. This relationship, influenced by mood, has been found in the preadolescent and adolescent population for somatic complaints. However, little is known in the case of younger children and when other adjustment outcomes are included. The objective of this work is to analyze the contribution of emotion awareness and mood upon different adjustment outcomes (somatic complaints, maladjustment, and peer sociometric status), in children aged 8-12 years old. Self-reported questionnaires and peer-nomination scales were administered to 1423 children (mean age = 9.8 years old). Results support the influence of emotion awa…

Who is at risk for ongoing dizziness and psychological strain after a vestibular disorder?

2009

Patients with vestibular vertigo syndromes often suffer from anxiety and depression, whereas patients with psychiatric disorders often experience subjective unsteadiness, dizziness, or vertigo. Thus, it has been hypothesized that the vestibular system may be interlinked with the emotion processing systems. The aim of the current study was to evaluate this hypothesis by correlating vestibular and psychiatric symptoms with the course of the disease over 1 year. This interdisciplinary, prospective, longitudinal study included a total of 68 patients with acute vestibular vertigo syndromes. Four subgroups of patients with benign paroxysmal positioning vertigo (BPPV, n=19), acute vestibular neuri…
