Obstructive sleep apnea in patients with chronic rhinosinusitis with nasal polyps: a cross-sectional study.

INTRODUCTION: Adults with chronic rhinosinusitis with nasal polyps (CRSwNP) often suffer from sleep disruption and sleep apnea. As the apneic profile of CRSwNP may differ from obstructive sleep apnea (OSA) classic patients without nasal polyps (NP), it may prove useful to define a new profile for OSA screening in these patients. The aim of the current study was to compare baseline characteristics and apneic profile of OSA patients with CRSwNP to OSA patients without NP. MATERIALS AND METHODS: Thirty-one apneic patients with CRSwNP and 62 apneic cases without NP were included in our study. Both groups underwent nasal endoscopy, Epworth Sleepiness Scale (ESS) evaluation, and overnight polysomnography (PSG). We additionally accessed anthropometric characteristics such as snoring, tiredness, observed apnea, high blood pressure, body mass index (BMI), age, neck circumference, male gender, and OSA risk via the STOP-Bang questionnaire. RESULTS: Although the patients were matched according to age and gender, the median BMI and STOP-Bang score were significantly higher in patients with OSA than in those with OSA and CRSwNP. Notably, the median ESS showed low somnolence and a low median apnea-hypopnea index in patients with CRSwNP, despite the fact that the lowest median oxygen saturation was not significantly different between groups. CONCLUSIONS: Anthropometric characteristics in individuals with apnea caused by CRSwNP were significantly different from those in individuals with typical. This finding will improve screening and treatment of apneic patients CRSwNP.

Children with nocturnal enuresis have posture and balance disorders.

INTRODUCTION: Integration of the neuromuscular system is required for maintaining balance and adequate voiding function. Children with enuresis have delayed maturation of the motor cortex, with changes in the sensory and motor systems. Along with various alterations, including the genetic, hormonal, behavioral, and sleep disturbances, and neuromotor and sensory deficits associated with nocturnal enuresis (NE) in children and adults, a consistent alteration in the posture of children with NE has been observed in the current practice. Because posture and the balance control system are strongly connected, this study aimed to investigate posture and balance in children and teenagers with NE. MATERIAL AND METHODS: A total of 111 children with enuresis were recruited to the enuretic group (EG) and 60 asymptomatic children made up the control group (CG). The participants were divided into two age subgroups: (A) 7-11 years old, N = 77 for EG/A, N = 38 for CG/A; and (B) 12-16 years old, N = 34 for EG/B, N = 22 for CG/B. Balance was assessed using an electronic force plate (100 Hz) to calculate the area of the center of pressure (COP) displacement. The COP is the point that results from the action of vertical forces projected onto the force plate. Sensory integration was analyzed using a 60-s trial with the subject standing under four conditions: (1) eyes open, stable surface; (2) eyes closed, stable surface; (3) eyes open, unstable surface; (4) eyes closed, unstable surface. Posture was assessed by placing reflective anatomical landmarks on the anterior superior iliac spine, the posterior superior iliac spine, the greater trochanter, and lateral malleolus. A photograph was taken while the subject stood quietly. The angles were obtained from landmark connections using software to assess the following posture variables: pelvic ante/retroversion and pelvic ante/retropulsion. RESULTS: The EG showed a greater area of COP displacement compared with the CG under all four sensory conditions and both subgroups, except for EG/B in condition 3. Regarding posture, EG showed higher pelvic anteversion angles than CG. CONCLUSIONS: Enuretic children showed forward inclination of the pelvis and had worse balance compared with control children.
