BACKGROUND The mechanisms of action of oral appliance therapy in obstructive sleep apnoea are poorly understood. Videoendoscopy of the upper airway was used during wakefulness to examine whether the changes in pharyngeal dimensions produced by a mandibular advancement oral appliance are related to the improvement in the severity of obstructive sleep apnoea. METHODS Fifteen patients with mild ...

INTRODUCTION Due to a lack of empirical data, the current understanding of the laryngeal mechanics in the passaggio regions (i.e., the fundamental frequency ranges where vocal registration events usually occur) of the female singing voice is still limited. MATERIAL AND METHODS In this study the first and second passaggio regions of 10 professionally trained female classical soprano singers we...

Abnormalities of the upper airway (UA) are frequently implicated as a cause of poor performance, exercise intolerance, or abnormal respiratory noise in the equine. Common abnormalities involving the function of the arytenoid cartilages include recurrent laryngeal neuropathy, arytenoid chondritis, and laryngeal dysplasia. Dorsal displacement of the soft palate (DDSP) and pharyngeal collapse affe...

Introduction Problems with swallowing, dysphagia, can occur in infants and children, which may have devastating effects. When a child with dysphagia is not treated properly, it may cause aspiration pneumonia, gastroesophageal reflux, and inability to develop and maintain adequate nutrition and hydration, and failure to thrive. This is why it is critical to properly evaluate children that are sh...

AIM To identify the clinical predictors and assist surgeons in their clinical management of obstructive sleep apnoea (OSA) - a prospective study with a new approach to analyse the static and dynamic upper airway morphology between patients with OSA and normal subjects. To introduce a new method of assessment for surgical outcome. MATERIALS AND METHODS Quantitative computer-assisted videoendos...

Összefoglaló. A Helicobacter pylori továbbra is a világ legelterjedtebb fertőzése: prevalenciája fejlődő országokban 70–80%, fejlett csökkenő tendenciát mutat. dél-magyarországi véradókban prevalencia 32%-ra csökkent. migráció befogadó ország számára fertőzés fokozott kockázatával jár. szövettani diagnózisban az immunhisztokémiai vizsgálat pontosabb hagyományos Giemsa-festésnél. mesterséges int...

Previous research found a relation between hormones and voice quality; however, the degree and type of this relationship is poorly understood, particularly regarding singing. Singers’ performances can be affected by contraceptive pills and by changes in concentrations of sex steroid hormones during the menstrual cycle (Lã et al., 2007). Pregnancy shows greater variation in concentrations of the...

Primary radiotherapy (RT) has been successfully employed for treatment of early glottic cancer for the past half century. However, local recurrences still occur in 5-35% of patients. Salvage options for persistent/recurrent glottic cancer include total laryngectomy, open neck partial laryngectomies (ONPLs) and transoral laser surgery (TLS). We performed a retrospective chart review of 35 patien...

Background: Studies with the latest technologies such as endoscopy with magnification and chromo endoscopy showed that various endoscopic aspects are clearly related to infection by Helicobacter pylori (HP). The description of different patterns of erythema in gastric body under magnification of images revived interest in identifying these patterns by standard endoscopy. Aim: Validate endoscopi...
