Polyclonal, newly derived T cells with low expression of inhibitory molecule PD-1 in tonsils define the phenotype of lymphocytes in children with Periodic Fever, Aphtous Stomatitis, Pharyngitis and Adenitis (PFAPA) syndrome.

Purpose: PFAPA syndrome is a benign, recurrent inflammatory disease of childhood. Tonsillectomy is one of the therapeutic options with a yet unexplained biological mechanism. We tested whether specific lymphocyte subsets recruited from blood to human tonsils participate in PFAPA pathogenesis.

Successful early neonatal repair of cleft lip within first 8 days of life.

Objective: In the children born with a cleft lip, surgery is the first step in correcting the inborn anomaly. In comparison with usually made 3-month surgery, benefits of the surgery in neonates have been reported: a very good wound healing, feeding facilitation, and good socialization of a child from neonatal age. The aims of the present study were to perform cheiloplasty in early newborns affected by the total cleft lip and palate (CLP) by the technique modified to search for optimum aesthetic result, and to assess the surgery outcome from qualitative and quantitative aspects.

Changes of orexin A plasma levels in girls with anorexia nervosa during eight weeks of realimentation.

Objective: Orexin A (OXA) is a hypothalamic neuropeptide involved in regulation of food intake and nutritional status. There are multiple disturbances of neuropeptide signaling described in girls with anorexia nervosa (AN), but OXA levels have not been addressed in this population to date. Therefore, we analyzed OXA levels of AN girls in this study.

Spectrum and frequency of SLC26A4 mutations among Czech patients with early hearing loss with and without Enlarged Vestibular Aqueduct (EVA).

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 and evaluated their clinical and radiological phenotype. Among 115 available HRCT/MRI scans we detected three MD (2.

Bacterial infection complications in children with cochlear implants in the Czech Republic.

Objective: Studies describing wound infections after cochlear implantation are rare. Meticulous operative techniques and sufficient surgical skill can help to avoid severe postoperative complications. Minor complications such as seromas, superficial wound infections, skin emphysema, and swelling can all be successfully treated using conservative methods.

Corrosive injury of the oesophagus in children.

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 oesophagoscopy; intensive medical therapy; nasogastric tube placement; and/or surgical intervention.

Changes in otoacoustic emissions and high-frequency hearing thresholds in children and adolescents.

With the aim of characterizing the loss of high frequency hearing sensitivity in children, hearing thresholds and otoacoustic emissions were measured in a group of 126 normal hearing children and adolescents aged from 6 to 25 years. The subjects were divided into four 5-year age groups. Hearing thresholds over a range of 125 Hz-12.
