Mutations in SLC26A4 cause Pendred syndrome (PS) - hearing loss with goitre - or DFNB4 - non-syndromic hearing loss (NSHL) with inner ear abnormalities such as Enlarged Vestibular Aqueduct (EVA) or Mondini Dysplasia (MD). We tested 303 unrelated Czech patients with early hearing loss (298 with NSHL and 5 with PS), all GJB2-negative, for SLC26A4 mutations(More)
Hereditary hearing loss (HL) is a very heterogeneous trait, with 46 gene identifications for non-syndromic HL. Mutations in GJB2 cause up to half of all cases of severe-to-profound congenital autosomal recessive non-syndromic HL, with 35delG being the most frequent mutation in Caucasians. Although a genotype-phenotype correlation has been established for(More)
OBJECTIVE This study examined a cohort of pediatric patients treated for suspected corrosive injury of the oesophagus in the ENT department between 1994 and 2003. METHODS During the study period we examined 337 patients. All patients were treated according to an individual diagnostico-therapeutic protocol that included: foremost, early rigid(More)
In this paper, we present a supporting structure for speeding up visibility queries needed for a 3D multi-goal path planning arising from a robotic coverage problem where goals are sensing locations from which an object of interest can be covered. Although such coverage problems can be addressed by a decomposed approach where sensing locations are(More)
Over the past few years, the ENT clinic in Motol has noticed an alarming increase in the number of cases of severe upper GIT injury in children, in the majority of cases caused by accidental ingestion of corrosives. Suicidal and homicidal cases in the paediatric population are rare. The following case study describes an interesting episode involving(More)
