All rapid responses

Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles or when it is brought to our attention that a response spreads misinformation.

From March 2022, the word limit for rapid responses will be 600 words not including references and author details. We will no longer post responses that exceed this limit.

The word limit for letters selected from posted responses remains 300 words.

Obstructuve sleep apnea and periodic limb movements

The presence of OSAHS (Obstructive sleep Apnea-Hypopnea syndrome) and
the concurrent signs of neurologic disease, in this case, periodic limb
movements has been studied recently.

The series by Chen R et al (2010) considered 229 consecutive diagnosis
of OSAHS patients, and 118 patients were detectedwith both OSAHS and
PLM. Some indexes were measured related to indicators and variables: total
time of sleep, percentage of sleep stages, REM latency, sleep
efficiency, lowest SpO2, oxygen reducing index, apnea-hypopnea index,
index of PLMs during sleep, PLMs with arousals.

Increase in sleep stage 1 ( p=0.04 ) was associated with increased PLM
index.

Sleep apnea and weight

The issue with weight is the single most important factor that leads
to sleep apnea. Even patients undergoing surgery involving the throat,
tonsils and tongue may be benefiting more from the post-op weight loss
than from the surgery itself. This is the first approach to helping
patients eliminate sleep apnea, and we at Lexington ENT help the patient
to understand and treat the weight issue before any other intervention.
