OBJECTIVE Upper airway resistance syndrome is a sleep-disordered breathing syndrome that is characterized by repetitive arousals resulting in sympathetic overactivity. We aimed to determine whether upper airway resistance syndrome was associated with poorly controlled hypertension. METHODS A total of 40 patients with resistant hypertension were enrolled in the study. All of the patients under...

OBJECTIVE To determine the effectiveness of distraction osteogenesis of the mandible for relief of airway obstruction in neurologically impaired children. DESIGN Prospective pilot study. SETTING Tertiary care children's hospital. PATIENTS Five children with upper airway obstruction secondary to hypotonia were identified by airway endoscopy, pulse oximetry, and polysomnography. Four childr...

Objectives The aim of the study was to analyse differences in pharyngeal airway dimensions and head posture between obstructive sleep apnea patients with and without morphological deviations in the upper cervical spine and to analyse associations between pharyngeal airway dimensions and head posture in the total sample. Material and Methods The sample comprised 53 obstructive sleep apnea (OSA...

background: potassium permanganate (pp) is a highly corrosive and deadly agent with a reported lethal dose of 10 g in adults. in this report, successful treatment of a patient poisoned with three times the lethal dose of pp is presented, and effective and early approach to such emergency toxicologic condition is discussed. case presentation:a 24-year-old woman presented to emergency room of our...

Introduction: Evaluation of upper airway space is a routine procedure in orthodontic diagnosis and treatment planning. Although limited insofar as they provide two dimensional images of three-dimensional structures, lateral cephalometric radiographs have been used routinely to assess airway space permeability. Cone-Beam Computed Tomography (CBCT) has contributed to orthodontics with information...

BACKGROUND Invasive methods requiring general anaesthesia are needed to sample the lung microbiota in young children who do not expectorate. This poses substantial challenges to longitudinal study of paediatric airway microbiota. Non-invasive upper airway sampling is an alternative method for monitoring airway microbiota; however, there are limited data describing the relationship of such resul...

Both allergic rhinitis and bronchial asthma are inflammatory diseases in the respiratory tract. The upper and lower airways share many anatomical, physiological, and histological properties. A close relationship between allergic rhinitis and asthma has been established, and the “united airway disease hypothesis” proposes that upper and lower airway diseases are both manifestations of a single i...

Spirometry flow-volume loop measurement is the screening test of choice to rule out obstructive lung diseases. Flow oscillations occasionally seen on flow volume loops, referred to as a "saw-tooth" sign, are thought to be due to an upper airway obstructive processes associated with upper airway collapsibility. Widely described in obstructive sleep apnea syndrome, flow oscillations have also bee...
