[New Swedish National care process for pediatric obstructive sleep disordered breathing].

Obstructive sleep disordered breathing (OSDB) is a spectrum from habitual snoring and labored breathing to obstructive sleep apnea (OSA), which is common and potentially serious in children. The process contains a new question at child care centers, directed at caretakers with children at age 18 months and 3 years, concerning habitual snoring (3 times a week or more). A primary care doctor verifies the suspicion of OSDB in case of a positive answer to one of 7 additional questions or 4 status findings (e.

Ultrastructural Characterization of Stem Cell-Derived Replacement Vestibular Hair Cells Within Ototoxin-Damaged Rat Utricle Explants.

The auditory apparatus of the inner ear does not show turnover of sensory hair cells (HCs) in adult mammals; in contrast, there are many observations supporting low-level turnover of vestibular HCs within the balance organs of mammalian inner ears. This low-level renewal of vestibular HCs exists during normal conditions and it is further enhanced after trauma-induced loss of these HCs. The main process for renewal of HCs within mammalian vestibular epithelia is a conversion/transdifferentiation of existing supporting cells (SCs) into replacement HCs.

Neurotrophic factor BDNF is upregulated in soft palate muscles of snorers and sleep apnea patients.

Objectives: Neuromuscular injuries are suggested to contribute to upper airway collapse and swallowing dysfunction in patients with sleep apnea. Neurotrophins, a family of proteins involved in survival, development, and function of neurons, are reported to be upregulated in limb muscle fibers in response to overload and nerve damage. We aimed to investigate the expression of two important neurotrophins, brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), in muscle fibers of uvula from snorers and sleep apnea patients and to compare these findings with pharyngeal function.
