Effects of Gabapentin Enacarbil on Cortical Arousals, Heart Rate, Blood Pressure and Anterior Tibialis EMG Responses Associated with PLMs in Restless Legs Syndrome
Objective: This study was conducted to investigate the effects of gabapentin enacarbil (GEn) on sleep EEG, heart rate (HR), blood presssure, anterior tibialis EMG activity (PLMs power) and subjective complaints in subjects with moderate to severe RLS and disturbed sleep.
Methods: This was a single site, single-blind, placebo run-in, fixed dose single group polysomnography (PSG) study. Eligible subjects (age 24-66 years) were treated with placebo for one week and GEn (600 mg/day) for 4 weeks. Two in-laboratory PSGs were collected for adaptation and baseline at the end of the placebo run-in period and for re-adaptation and efficacy assessment at the end of the 4-week treatment period. The primary endpoint was the difference in PSG derived cortical arousal intensity (arousal scale, 0-9) associated with PLMs between 4 weeks of treatment with GEn and placebo. Secondary endpoints included changes in HR responses (ΔHR), nocturnal systolic blood pressure (SBP) changes (>10 mmHg) secondary to PLMs and PLMs power. Other PSG and subjective measures were assessed.
Results: Of 20 subjects enrolled, 18 completed the study. Subjects treated with GEn did not show significant improvements in cortical arousal intensity and ΔHR. However, subjects showed reduced PLMs power (p= 0.013) and associated reductions in nocturnal SBP per hour of sleep (p= 0.041) GEn showed significant improvement in other PSG parameters and subjective endpoints.
Conclusion: The data suggests that GEn reduces the frequency and power of PLMs and the corresponding SBP changes in subjects with RLS. Despite reducing the total number of PLM associated arousals and nocturnal HR, the study did not demonstrate consistent effects of GEn on cortical arousal intensity and corresponding HR changes associated with PLMs.

To Evaluate the Efficacy of Ultrasound Guided Distraction Osteogenesis by Evaluating Qualitative Estimation of Bone Fill at Regeneration site and Management of Severe Mandibular Hypoplasia Secondary to Obstructive Sleep Apnoea: A Case Report
Distraction Osteogenesis (DO) is an established method for correction of developmental anomaly of the facial skeleton. The early
beginning of urgent surgical corrections are allowed in smaller age as even small children suffering from bilateral severe mandibular
deficiency who are often associated with breathing and swallowing disorder caused by glossoptosis.
