[Oculographic findings in 145 patients with benign paroxysmal positional vertigo].

OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) can be produced by specific manoeuvres and be studied by electrooculography (EOG). It allows an exhaustive study of features in the positional nystagmus. Although most of the patients with BPPV express typical nystagmus, there exists a group of them that exhibit a non typical form. In this work, a comparative study was carried out between two groups of patients. MATERIAL AND METHODS: We have studied retrospectively 145 patients with BPPV and Dix-Hallpicke (D-H) positive manoeuvre registered by EOG techniques. All patients were explored in a complete EOG tests. Two groups were identified: typical response/atypical response according to the features of nystagmus response. Possible alterations in other EOG tests in each group were investigated and differences between both types of response were analyzed. RESULTS: 83.5% of cases showed typical nystagmus and atypical in the rest. Other EOG alterations observed in these patients, were (group typical response/atypical response): caloric hypofunction (17.3%/23%), positional nystagmus (12.4%/62.5%), alterations in visual-oculomotor function tests (10%/50%). CONCLUSIONS: Frequent alterations were observed in the classic manoeuvres and also in the rest of EOG tests. Probably atypical response in the first is due to or can explain the existence of the second.

[Benign paroxysmal positional vertigo of the horizontal semicircular canal].

OBJECTIVE: Assesment of 8 new cases of benign paroxysmal positional vertigo of the horizontal semicircular canal (BPPV-HC), since this variant of benign positional vertigo occurs rarely. An oculographic study of features in the positional response was carried out. Electrooculograpy (EOG) allows an exhaustive study of positional nystagmus. MATERIAL AND METHODS: We have studied retrospectively 8 patients with BPPV-HC and positive head rotation manoeuvre registered by EOG techniques. Possible alterations in other EOG tests in the group of patients were analyzed. RESULTS: Most of the patients (7/8) expressed bilateral horizontal geotropic changing-direction nystagmus. One patient exhibited apogeotropic horizontal nystagmus. 5/8 cases showed caloric hypofunction. CONCLUSIONS: We have proven that BPPV-HC is an uncommon disorder. In most of the cases, provocative manoeuver generates bilateral horizontal geotropic changing-direction nystagmus that probably is due to canalitiasis of the horizontal semicircular canal. The rest, a few cases, exhibit apogeotropic horizontal response that can be secondary to cupulolitiasis or location particles in the anterior portion of the horizontal canal. A caloric test showed abnormal in many and can help to locatize the affected ear.

[Electrooculography. Its value in the diagnosis of the patient with a balance disorder].

INTRODUCTION: Controversy persists on the value of electrooculography (EOG) in the diagnosis of the unbalanced patient. The aim of this study has been to know the utility of EOG in the diagnosis of patients with equilibrium disorders. MATERIAL AND METHODS: We have examined 1000 patients in whom EOG test has been performed for unbalance symptoms. Results have been classified in peripheric or central pattern. Those patients included in the central pattern group have been compared with the results of imaging techniques. RESULTS: 45.7% of EOG performed showed pathological signs, 29.2% were of peripheral characteristics and 16.5% of central ones, of whom 6% showed different pathologies in the imaging test. DISCUSSIONS AND CONCLUSIONS: EOG in now a days of high value in the diagnosis of unbalanced patient, specially in those cases in which other clinical explorations were normal.

[Thyroid actinomycosis: a case report].

Actinomycosis is nowadays a not very common festered chronic infection. Cervicofacial actinomycosis is the most frequent clinical form, and it is due in most cases to Actinomyces israelii. Thyroid actinomycosis has been scarcely described in the literature. The lesions, that are characterized to be notably indurated and to contain multiple abscesses that drain to the surface through sinus tracts, frequently simulate other infective clinical entities and often neoplasms, therefore the diagnosis is delayed in the time. From a case of thyroid actinomycosis diagnosed and treated in our service which was initial diagnosed as a thyroid neoplasm, we revise the cases described in the literature and we make a point in the difficulty to arrive to the diagnosis of this entity.

[Study of 1,000 patients with disequilibrium].

We present a series of one thousand patients tested with electronystagmography (ENG) for evaluation of complaints of unstability. Personal data and electronystagmographic results are analysed.
