Seasonality of bruxism: evidence from Google Trends
AbstractObjectiveSeasonality of bruxism and its symptoms has not been tested and reflects a major niche in our understanding and the epidemiology of bruxism. Our aim is to use the Google Trends data to examine whether there was a seasonal pattern in the Google search volumes of bruxism and its symptoms on a population basis.MethodsIn the observational, ecological research, we interrogated Google Trends for the following query terms: [bruxism] and [teeth grinding + teeth clenching] to obtain the internet search query volume. These queries were searched within the USA, the UK, Canada, and Australia from January 2004 to Decem...

The correct measurement of oxygen saturation at high altitude.
CONCLUSIONS: The correct pulse oximetric determination of SpO2 at high altitude requires a standardized measurement procedure; the investigator is familiar and trained. Anyway, the measurements have to be done in the continuous mode of the pulse oximeter over a sufficient timeframe (3 SpO2-fluctuation cycles; 2-3 min). We recommend to record the maximum and the minimum value of the measurement interval and to use a pulse oximeter device with memory function.

Long-term adherence to ambulatory initiated continuous positive airway pressure in non-syndromic OSA children.
CONCLUSION: In our population, mean CPAP adherence defined in hours per night was high and did not decrease during the 24-month follow-up. These findings support the feasibility of ambulatory CPAP initiation in non-syndromic OSA. The high CPAP adherence is expected to be associated with improvements in neurocognition, and in metabolic and cardiovascular parameters.
