[Comprehensive approach to vertigo: Diagnostic algorithm, causes, treatments, and referral criteria from the perspective of primary care. SEMERGEN consensus document]

Vertigo is a common symptom that can have various causes and may require a comprehensive approach for its diagnosis and treatment from primary care. A diagnostic algorithm based on the classification proposed by the Otoneurology Commission of the SEORL-PCF is suggested, which facilitates the classification of the different types of vertigo and provides referral criteria for patients from primary care to other specialties. A review of the available treatments based on the underlying cause is conducted for appropriate therapeutic management. This document is expected to become a valuable tool for professionals treating patients with vertigo. The document is based on scientific evidence and on the experience of experts in the field from various medical specialties; and seeks to improve the understanding and clinical approach to acute vertigo from primary care.

Disability in patients with Menière's disease following the use of two different treatment modalities: betahistine and intratympanic gentamicin

OBJECTIVE

The objective of this study was to assess the level of residual disability and handicap in patients with Menière's disease (MD) that were free of new vertigo spells 2 years after having been administered treatment with either oral medication or with intratympanic gentamcin.

SETTING

University hospital. Tertiary medical center.

MATERIAL AND METHOD

40 patients with MD were included in this study, of which 20 were treated with oral medication (betahistine) and 20 with intratympanic gentamicin; intratympanic gentamicin was for patients considered failures for the oral medication treatment. All of them are free of new vertigo in the 16-24 month period after beginning the treatment. They were matched by age and disease duration. Disability and handicap were assessed with conventional questionnaires at the time of inclusion and 2 years after beginning oral medication or ended the intratympanic gentamicin treatment. According to the treatment two groups were created: oral medication treatment and intratympanic gentamicin treatment.

RESULTS

The amount of disability before treatment was higher in patients treated with intratympanic gentamicin than in those under oral medication; However, after treatment when no more vertigo spells takes place, this disability is significantly reduced and becomes similar for both groups of patients. In patients treated with oral medication the items reflecting the intensity of vertigo spell, the impact of vertigo in daily activities, the perception of quality of life and level of somatization do not show a significant reduction.

CONCLUSION

The number or frequency of vertigo spells are very relevant for the process of disability and handicap of patients with MD when that is low or when oral medication is sufficient to eliminate vertigo spells. However when that number is high and the only possibility to arrest those vertigo spells is the use of intratympanic gentamicin, fear of vertigo must be considered as an associated problem for the patient.

[Characterisation of the influence exerted by the visual factor in patients with balance disorders]

INTRODUCTION

Visual information provides data about the position and movement of the head with respect to objects and serves as a source of reference for the proper perception of verticality. It also plays a specific role in postural control by modifying the efficiency of the vestibular and proprioceptive responses.

AIMS

Our aim was to determine how visual information interacts with the symptoms of patients with vertigo, dizziness or instability and to find out the degree of disability it produces.

PATIENTS AND METHODS

A study was conducted in 200 patients who had visited because of dizziness, vertigo, instability or loss of balance. We analysed the aspects related to the clinical symptoms of the patients. First, we examined the influence visual stimuli have on the symptoms of vestibular disease itself and their repercussions on the situation between crises. Second, the degree of disability was evaluated on the specific DHI (Dizziness Handicap Inventory) questionnaire.

RESULTS

As regards the influence exerted by visual stimulation on the main symptoms, 77.5% reported that it had no effect and 21% said that it made them worse. With regard to the influence of visual stimulation during the intercritical period, it was of no relevance in 53.5% of patients, 26.5% were unaffected, it had an exacerbating effect in 4% and in 7.5% it induced it. Different disorders were observed depending on the type of disease suffered by the patient, and disability was greater according to the influence exerted by the visual factor.

CONCLUSIONS

Postural adjustments induced by visual stimuli are capable of triggering instability with serious consequences.
