Resumen Introduccion Existen amplios estudios e importantes controversias sobre el empleo de los actuales telefonos 0moviles y eventuales afecciones sistemicas o aparicion de tumores, pero no se conoce apenas sobre su posible implicacion en la generacion precoz de hipoacusia. Pacientes y metodos En 323 voluntarios sanos y normoacusicos usuarios habituales de telefonia movil se efectuo evaluacion audiometrica al inicio del empleo del aparato y a los tres anos del mismo, asi como una encuesta sobre el tiempo aproximado de uso diario y anual que efectuaban del sistema. Un grupo control sano y normoacusico no usuario de telefonia movil fue igualmente estudiado. Resultados Los individuos estudiados efectuaron 24,3±8,2 contactos activos entre llamadas realizadas y recibidas, lo que supuso un total de 50,4±27,8 dias de empleo del telefono movil en tres anos. La grafica audiometrica en casos y controles fue similar al inicio del estudio. En el seguimiento a tres anos los casos mostraron una elevacion del umbral e audicion por via aerea entre 1 y 5 dB HL mas que los controles en las frecuencias conversacionales (p Conclusiones El empleo de telefonia movil entre usuarios frecuentes a medio plazo permite detectar ligeras perdidas de audicion no observadas en no usuarios, si bien el motivo ultimo de este desorden auditivo no queda demostrado con los datos obtenidos.

Resumen Objetivo Evaluar la influencia de diferentes hallazgos otoscopicos sobre la termometria corporal en ninos con un sensor timpanico de infrarrojos Pacientes y metodos Con sistemas Thermoscan se comparo la temperatura corporal en oidos derecho e izquierdo sanos, asi como en ninos con otoscopias alteradas, comparando su valor con el oido contralateral normal. Su fiabilidad se estudio midiendo los indices de precision y exactitud a diversas temperaturas Resultados La temperatura sobre oidos sanos no demostro diferencias derecha/izquierda, y los coeficientes de variacion intra/interensayo fueron siempre inferiores a 0,34%. La termometria timpanica se elevo en la otitis externa aguda una media de 0,36oC (p Conclusiones Estas condiciones modifican la temperatura medida por termometria timpanica con infrarrojos, no debiendose emplear este sistema. La otitis media, la perforacion timpanica y el drenaje transtimpanico no modificaron la termometria

We show two atypical Cogan's syndrome cases in forty-seven and fifty-six years old individuals. Characteristical symptoms of the syndrome were detected in both (interstitial keratitis, sensorineural deafness and vestibular dysfunction), but they could be considered as unusual because of the association of systematic symptoms and an onset with hearing loss. In both cases there was an increase in erythrosedimentation rate and immunoglobulins levels, as well as high titles for rheumatoid factor and non-specific autoantibodies. By means of a Western-blot technique, several chochlear antibodies with distinct molecular weight were detected, but the 68 KD appeared in both. Metil-prednisolone treatment did not avoid ocular and auditive reactivation in ne of the patients.

We report two cases of sudden deafness which appeared during vaso-occlusive crisis of a sickle cell anaemia (homozygous form of disease) and a sickle cell trait (heterozygous form) in two males aged sixteen and twenty-two, respectively. A high erythrocyte aggregability and low deformability were proved in both young men. Although hearing disorders have been reported in this disease, a sudden onset is not common. The treatment used was useful in the removal of painful crisis and infections, but deafness did not improve in either of then.

Wide studies and substantial controversies build on utilization of actual mobile phones and appearance of systemic disorders or even tumours, but there is no knowledge about an eventual involvement on early hearing loss.In a group of three hundred and twenty-three healthy and normoacoustic volunteers who were usual costumers of mobile phones an audiometric evaluation was made at the beginnig of its use and three years later, inquiring about the periods of time per day and year employed on direct contacts with phone. A healthy and normoacoustic control group of non users was studied too.Cases carried out 24.3 +/- 8.2 active contacts, reaching 50.4 +/- 27.8 days of mobile phone employment in three years. Audiometric curve was similar in cases and controls at the beginning of the study. After this follow-up, cases showed an increase on hearing threshold between 1 and 5 dB HL more than controls in speech tones (p0.001). Moreover, there was a trend to correlate time of phone use to hearing impairment, but this finding did not result statistically significative.Frequent management of mobile phones in a middle period of time allows to detect a mild hearing loss, but the cause of this disorder keeps unclear.

To evaluate the influence of different otoscopic findings on body thermometry in children using an infra-red tympanic thermometer.Body temperature was measured on healthy right and left ear canals with Thermoscan systems. Moreover, it was determined on children with altered otoscopy, companng to normal contralateral ear. To assess its diagnostic fiability, accuracy ratios were calculated in different temperatures.Temperature measured bilaterally did not offer differences, and intra/interassay variation ratios were always less than 0.34%. Acute otitis externa increased tympanic thermometry a mean of 0.36 degrees C (p0.001), and cerumen and previously radical surgery decreased a mean of 0.62 and 0.53 degrees C, respectively (p0.001).The conditions mentioned before modify body thermometry if measured by infra-red tympanic thermometer. So, this system must be avoided in these circumstances. Otitis media, fluid in middle ear, tympanic perforation and ventilation tubes did not modify thermometric results.
