Hearing loss changes the auditory brain, sometimes maladaptively. When deprived of cochlear input, central auditory neurons become more active spontaneously and begin to respond more strongly and synchronously to better preserved sound frequencies. This spontaneous and sound-evoked central hyperactivity has been postulated to trigger tinnitus and hyperacusis, respectively. Localized hyperactivi...
A woman aged 73 presented with a four-week history of hypoacusis and low-density clear discharge from her right ear, with no history of traumatic or surgical events. Physical examination showed right middle ear invasion and discharge of a clear liquid, which was suggestive of CSF caused by tympani defects. Left middle ear invasion presented with no other condition. Computerised tomography (CT) ...
BACKGROUND Carvajal syndrome is an autosomal dominant or autosomal recessive disorder, manifesting with dilated cardiomyopathy, woolly hair, and palmoplantar keratoma. Additional manifestations can be occasionally found. Carvajal syndrome may be due to mutations in the desmocollin-2, desmoplakin, or plakophilin-2 gene. METHODS AND RESULTS We report a family with Carvajal syndrome which additi...
Usher’s syndrome is an autossomal recessive disease characterized by pigmentary retinopathy (PR) and bilateral sensorineural hypoacusis. Von Graefe and Liebreich were the first to publish a paper describing the association between PR and deafness. The incidence is 3 to 4.4 per 100,000 people. The prevalence is 3% to 6% among auditory impaired people.4 It may be subdivided into four types of whi...
INTRODUCTION In children, hypoacusis, or conductive hearing loss, is usually acquired; otitis media with effusion is the most common etiology. However, in some cases this condition is congenital, ranging from deformities of the external and middle ear to isolated ossicular chain malformations. The non-ossicular anomalies of the middle ear, for instance, persistent stapedial artery and anomaly o...
BACKGROUND Accumulating evidence suggests that vitiligo is a systemic disease affecting the entire pigmentary system. AIM To investigate the subclinical abnormalities of melanin-containing cellular elements of the auditory system in patients with vitiligo. METHODS We studied the conventional audiometric investigations and brainstem auditory evoked responses (BAERs) of 57 active patients wit...
UNLABELLED Otomycosis is a fungal infection of the external ear canal with only a few studies about its real frequency in Brazil. AIM to evaluate otomycosis frequency and characteristics in patients with clinical suspicion of external otitis. STUDY DESIGN Retrospective study with transversal cohort (2000-2006). MATERIALS AND METHODS 103 patients were assigned to mycological diagnosis (dir...
With interestwe read the article by Zanolini et al. about a 21 yomale with exercise-intolerance since age 7 y, recurrent vomiting since age 17 y, muscle wasting, decreased tendon reflexes, high-arched palate and mal-occlusion detected at age 20 y, exercise-induced supraventricular tachycardia, and lactic acidosis due to a ND2 mutation [1]. The patient profited from coenzyme-Q [1]. We have the f...
Introducción y objetivo: En los últimos años se ha detectado un aumento en la incidencia de efectos adversos ototóxicos sobre el oído interno por medicamentos y/o vacunas, que parecen haberse incrementado exponencialmente durante pandemia COVID-19. El análisis las notificaciones bases datos sanitarias como Fedra (España) o EudraVigilance (Europa) puede permitir profundizar conocimiento nuevos f...
Mitochondrial disorders (MIDs) require biochemical or genetic investigations for being diagnosed. In some cases, however, the diagnosis can be suspected upon the syndromic phenotype or upon clinical presentation and family history, as in the following case. The patient was a 74-year-old male admitted for worsening of pre-existing left-sided ptosis and ophthalmoparesis after a birthday party. Th...
