Case report supporting that the Barber-Say and ablepharon macrostomia syndromes could represent one disorder.
2009
We report on a 7-year-old girl with unequivocal features of Barber-Say syndrome (BSS): generalized hypertrichosis especially at the back, dry lax skin, macrostomia, thin lips, cup-shaped ears, bulbous nose, hypoplastic nipples, and abnormal external genitalia. She also demonstrated conductive hearing impairment and microblepharon. BSS has been reported with ectropion (not present in our patient), but ablepharon and microblepharon (i.e., absent or hypoplastic eyelids) have always been considered as hallmarks of ablepharon macrostomia syndrome (AMS). This is the first report of microblepharon in BSS. Other authors have discussed that BSS and AMS could possibly represent one syndrome, and our …
Detrimental noise effects on brain's speech functions.
2009
Background noise has become part of our everyday life in modern societies. Its presence affects both the ability to concentrate and communicate. Some individuals, like children, the elderly, and non-native speakers have pronounced problems in noisy environments. Here we review evidence suggesting that background noise has both transient and Sustained detrimental effects on central speech processing. Studies on the effects of noise on neural processes have demonstrated hemispheric reorganization in speech processing in adult individuals during background noise. During noise, the well-known left hemisphere dominance in speech discrimination became right hemisphere preponderant. Furthermore, l…
Tinnitus and tinnitus disorder: Theoretical and operational definitions (an international multidisciplinary proposal)
2021
As for hypertension, chronic pain, epilepsy and other disorders with particular symptoms, a commonly accepted and unambiguous definition provides a common ground for researchers and clinicians to study and treat the problem. The WHO's ICD11 definition only mentions tinnitus as a nonspecific symptom of a hearing disorder, but not as a clinical entity in its own right, and the American Psychiatric Association's DSM-V doesn't mention tinnitus at all. Here we propose that the tinnitus without and with associated suffering should be differentiated by distinct terms: "Tinnitus" for the former and "Tinnitus Disorder" for the latter. The proposed definition then becomes "Tinnitus is the conscious a…
Hörscreening bei Neugeborenen. Vergleichende Untersuchungen und Kostenanalysen mit verschiedenen Geräten1
2000
BACKGROUND The necessity of screening examinations in newborns today cannot be denied. Up to now, it has only been achieved in a few countries to introduce a general hearing screening for newborns. METHODS We examined 100 newborns (200 ears) at their third day of life. All ears were evaluated with the TEOAE-screening-device ECHOSCREEN. In addition, we carried out BERA screening examinations with the ALGO PORTABLE or with the EVOFLASH on 100 of these 200 ears. As a reference method, we utilized TEOAE-examinations with the ILO-88 for all ears. RESULTS 4.5% of the 200 ears examined with the ECHOSCREEN were conspicuous due to accumulation of earwax problems. With the ALGO-system, none of the ea…
Changes on blood filterability in patients with fluctuant hearing loss
2006
Abstract We conducted a two-year follow-up of thirteen subjects with fluctuating sensorineural hearing loss, measuring their blood filterability (BF) and correlating it to the onset of episodes of deafness. We observed a decrease in the BF levels of all the patients when they experienced hearing loss. When the patients recovered their normal level of hearing, the BF also increased. The use of reactive techniques to avoid these decreases in BF could potentially prevent or correct fluctuating deafness.
Epidemiology of Usher Syndrome in Valencia and Spain
2004
<b>Objective:</b> To obtain epidemiological data on the prevalence of the different types of Usher syndrome (US) in Spain, since these data were missing; to estimate the proportion of sporadic cases among simplex families, and calculate the prevalence of the Usher syndrome in a homogeneous population from Eastern Spain (3,875,234 inhabitants) that is representative of the Spanish population. <b>Methods:</b> Otological, ophthalmological and genetic studies were performed in 89 US patients from 46 families and subjected to statistical and segregation analysis. <b>Results:</b> 41.6% of them suffered US type I, 46.1% type II, and in 12.3% the classification r…
Síndrome de Susac de presentación ocular atípica
2007
espanolCaso clinico: Mujer de 25 anos de edad afecta de encefalopatia y perdida auditiva neurosensorial, remitida a nuestro servicio para confirmar un sindrome de Susac por presentar una disminucion de agudeza visual bilateral. En la exploracion funduscopica se aprecio una microangiopatia retiniana periferica. Discusion: El sindrome de Susac se caracteriza tipicamente por la triada encefalopatia, perdida auditiva neurosensorial, y oclusiones de ramas arteriales retinianas. En nuestro caso las alteraciones oculares eran atipicas, apreciandose amputacion de vasos terminales con cumulo de microaneurismas en retina periferica de ambos ojos.

The role of fissula ante fenestram in unilateral sudden hearing loss
2016
The cause of unilateral sudden sensorineural hearing loss (SNHL) remains unclear in many clinical cases. Perilymphatic leakage through a fissula ante fenestram (FAF) fistula is one possible reason. We present four clinical cases with proven FAF fistula, discovered during surgical exploration. All patients experienced partial hearing recovery after surgical coverage of the fistula. We suggest FAF as a possible site for perilymphatic leakage, representing an anatomical correlate for sudden unilateral SNHL. We recommend early exploratory tympanotomy with special attention to the bony region, anterior to the oval window, in cases of severe sudden SNHL and suspected FAF.
Subarachnoid Hemorrhage Revealing Moyamoya Syndrome in a Patient With May-Hegglin Anomaly.
2017
Etude de cas; Introduction: Moyamoya syndrome is a rare progressive cerebrovascular occlusive disease for which several associated conditions have been described. Case Report: We report the case of a 76-year-old woman with a history of May-Hegglin anomaly who presented with an isolated unusual diffuse headache. Initial laboratory investigations showed only thrombocytopenia (platelet count 95000/mu L). Unenhanced brain computed tomography scan revealed a small subarachnoid hemorrhage in the left frontal lobe. Computed tomography angiography showed occlusion of the terminal portion of the left internal carotid artery (ICA) and narrowing of the terminal portion of the right ICA with abnormal c…
Imaging of inner ear malformations: a primer for radiologists
2021
AbstractIn the multidisciplinary management of patients with inner ear malformations (IEMs), the correct diagnosis makes the differences in terms of clinical and surgical treatment. The complex anatomical landscape of the inner ear, comprising several small structures, makes imaging of this region particularly challenging for general radiologists. Imaging techniques are important for identifying the presence and defining the type of IEM and the cochlear nerve condition. High-resolution magnetic resonance imaging (MRI) sequences and high-resolution computed tomography (HRCT) are the mainstay imaging techniques in this area. Dedicated MRI and HRCT protocols play an important role in the diagn…
