Effect of rapid maxillary expansion on monosymptomatic primary nocturnal enuresis.
    The Angle orthodontist, 2015, Volume: 85, Issue:1

    To evaluate the effects of rapid maxillary expansion (RME) on nocturnal enuresis (NE) related to the nasal airway, nasal breathing, and plasma osmolality (as an indicator for antidiuretic hormone).. Nineteen patients with monosymptomatic primary NE, aged 6-15 years, were treated with RME for 10-15 days. To exclude a placebo effect of the RME appliance, seven patients were first treated with a passive appliance. Computed tomography of nasal cavity, rhinomanometric, and plasma osmolality measurements were made 2-3 days before and 2-3 months after the RME period. RME effects on NE were followed for three more years.. Two to three months after the expansion there were significant improvements in the breathing function and a decrease in the plasma osmolality. NE decreased significantly in all patients after the RME period, and all patients showed full dryness after 3 years.. This study demonstrates that RME causes complete dryness in all patients, with significant effects on pathophysiological mechanisms related to NE.

Effects of short term forced oral breathing in rat pups on weight gain, hydration and stress.
    Physiology & behavior, 2011, Feb-01, Volume: 102, Issue:2

    Nasal obstruction is a risk factor in sleep-disordered breathing with a negative impact on the quality of life in humans. We investigated hydration changes produced by short term reversible, bilateral, nasal obstruction in young developing rat pups. Physiological parameters of growth (weight gain and gastric content weight) and dehydration were analyzed during two periods; during nasal obstruction at post-natal day 8 (days 9, 11 and 13), plus 7 and 90 days after recovery of nasal breathing (day 15 and adulthood). Body weight gain in oral breathing rat pups was slower compared to controls. Gastric weight was decreased significantly only in oral breathing rat pups on days 9 and 11 while plasma osmolality and vasopressin levels increased (indicators of dehydration). There were no differences between controls and treated rat pups by day 15, or at adulthood. Short term nasal obstruction-induced forced oral breathing, decreased gastric content which had a negative impact on growth and blood glucose concentration in the short term for female rat pups. Plasma corticosterone levels increased during the dehydration but were normal in males by 90 days. This could be a model for blocked nose syndrome in the newborn. Possible long term consequences on development are discussed.
