Cervical spine radiographs in patients with vertigo and dizziness.

OBJECTIVE: The purpose of this study is to investigate the role of cervical radiography in the study of patients with vertigo and dizziness. PATIENTS: This is a retrospective single-institution case series study of 493 patients suffering from vertigo and dizziness who were referred (from January 2011 to December 2012) to the hospital to study those symptoms. METHODS: We studied cervical radiographies, CT and MRI of the cervical spine made in the sample and the radiological findings. We analyzed demographic characteristics, presence of psychiatric pathology and emergency assistance due to vertigo in patients who have undergone cervical study. RESULTS: A total of 57% of patients had cervical radiography made; this was more frequent in women, Spanish people, with psychiatric pathology and who have gone to the emergency department for vertigo (p < 0.05). Degenerative changes were found in 74.1% of the patients with radiography made, more frequently at an older age, osteophytes in 49.5% and abnormal cervical lordosis in 37.1%. CONCLUSIONS: There are sociodemographic factors that influence in the request for cervical radiographs in patients with vertigo and dizziness. Given the suspicion of cervical vertigo, we do not consider that the findings in the radiographs help in the diagnosis. In our opinion, an excessive use of cervical radiography is made in patients with vertigo and dizziness.

Recommendations on the use of neuromonitoring in thyroid and parathyroid surgery. / Recomendaciones sobre el uso de la neuromonitorización en cirugía de tiroides y paratiroides.

INTRODUCTION: Thyroid and parathyroid surgery (TPTS) is associated with risk of injury to the recurrent laryngeal nerve, superior laryngeal nerve and voice changes. Intraoperative neuromonitoring (IONM), intermittent or continuous, evaluates the functional state of the laryngeal nerves and is being increasingly used. This means that points of consensus on the most controversial aspects are necessary. OBJECTIVE: To develop a support document for guidance on the use of IONM in TPTS. METHOD: Work group consensus through systematic review and the Delphi method. RESULTS: Seven sections were identified on which points of consensus were identified: indications, equipment, technique (programming and registration parameters), behaviour on loss of signal, laryngoscopy, voice and legal implications. CONCLUSIONS: IONM helps in the location and identification of the recurrent laryngeal nerve, helps during its dissection, reports on its functional status at the end of surgery and enables decision-making in the event of loss of signal in the first operated side in a scheduled bilateral thyroidectomy or previous contralateral paralysis. The accuracy of IONM depends on variables such as accomplished technique, technology and training in the correct execution of the technique and interpretation of the signal. This document is a starting point for future agreements on TPTS in each of the sections of consensus.

Vertigo and dizziness in hospital: Attendance, flow and characteristics of patients. / Vértigo y mareo en el hospital: frecuentación, flujo y características de los pacientes.

INTRODUCTION AND OBJECTIVES: Vertigo and dizziness as symptoms are frequent in the population. They are present in a wide range of pathologies and it is usually difficult to make an accurate diagnosis. The general objective of this study is to obtain the information to evaluate vertigo and dizziness in the hospital setting. The specific objectives are: to estimate the burden of these symptoms at the hospital; to study patients' conditions and to detail the flow of these patients inside the hospital. METHODS: Observational descriptive study. We made a search of the referral proposals made in 2011 and 2012 to the hospital because of vertigo symptoms. The patients' demographic and clinical characteristics, and the administrative details of the referrals were analysed. RESULTS: A total of 558 proposals were analysed corresponding to 494 patients. Vertigo accounted for 0.5% of all referrals made from Primary Care to the hospital. Sixty-three percent of the sample were women; the average age was 58 years. Eighty-eight percent of the patients were evaluated by Otorhinolaryngology, 24% by Neurology. Thirty point eight percent consulted on 3 or more occasions for the symptom. Sixteen percent were assessed for psychiatric conditions in the hospital. CONCLUSIONS: Vertigo as a symptom is a significant burden in the hospital setting. The patients who suffer it consult on several occasions and are assessed by different specialties. This implies in some cases an excessive and ineffective flow of patients. In our setting, otorhinolaryngology is the main department to treat vertigo and dizziness patients.
