ABSTRACT
OBJECTIVE: To develop a new method to quantify visually-enhanced vestibulo-ocular reflex (VVOR) gain, in patients with vestibular function loss, that is mathematically suitable given the nature of the test, and determine the reliability of the method by comparing results with those of the gold standard, the video head impulse test (vHIT). MATERIALS AND METHODS: We developed a new method for VVOR gain quantification and conducted a cross-sectional study in patients diagnosed with vestibular function loss and controls, all participants undergoing both a VVOR test and a vHIT. We measured VVOR gain with three different methods: area under the curve (AUC), slope regression, and a Fourier method (VVORAUC , VVORSP , and VVORFR , respectively); and compared these gain values with vHIT gain calculated using the AUC method. RESULTS: Overall, 111 patients were included: 29 healthy subjects and 82 patients with vestibular function loss. Intraclass correlation coefficients (ICC(1,1)) between gain from the gold standard and each of the VVOR gain methods were: 0.68 (CI: 0.61-0.75) for VVORAUC , 0.66 (CI: 0.58-0.73) for VVORSP and 0.71 (CI: 0.64-0.77) for VVORFR . No interference was found between VVOR gain calculation methods and potentially influential variables considered (p ≥ 0.98). CONCLUSION: The new method for quantifying VVOR gain showed good concordance with the vHIT method.

OBJECTIVES: Sialoendoscopy is a procedure used to visualize the salivary ducts and their pathology. It can be used either as a diagnostic method to rule out inflammatory processes in the parotid and submandibular glands (diagnostic sialoendoscopy) or to treat pathological areas (stenosis, extract foreign bodies or sialolithiasis) through the use of appropriate instruments (interventionist sialoendoscopy). We attempt to prove a declining rate of salivary gland excision. PATIENTS AND METHOD: Sialoendoscopy was performed in 8 patients. RESULTS: Of these, 50 % of patients were diagnosed as having sialolithiasis and the other 50 % had chronic sialoadenitis. In patients with sialolithiasis, sialoendoscopy allowed the extraction of the calculus in two patients (50 %). In the remainder, sialoendoscopy provided confirmation of the diagnosis in all cases. CONCLUSIONS: Sialoendoscopy is a new technique for use in the diagnosis, treatment and post-operative management of sialolithiasis, sialoadenitis and other salivary gland pathologies.

Objetivos: La sialoendoscopia es un procedimiento cuya finalidad es visualizar los conductos salivales y sus procesos patológicos. Se utiliza como método diagnóstico, para descartar procesos inflamatorios de las glándulas (sialoendoscopia diagnóstica) y para tratar áreas patológicas (estenosis, retirar cuerpos extraños o cálculos), mediante instrumental (sialoendoscopia intervencionista). Queremos mostrar la disminución de extirpación glandular. Pacientes y método: Se estudia a 8 pacientes intervenidos con sialoendoscopia. Resultados: En el 50 % se trataba de sialolitiasis y en el otro 50 %, de sialodenitis crónica. En las sialolitiasis la sialoendoscopia intervencionista permitió extraer el cálculo en 2 (50 %) casos. En el resto la sialoendoscopia permitió confirmar el diagnóstico en todos los casos. Conclusiones: La sialoendoscopia es un nueva técnica que nos permite diagnosticar, tratar y hacer un adecuado seguimiento de las sialodenitis, sialolitiasis y otras afecciones glandulares
