  • Sleep Bruxism and Sleep-Disordered Breathing
    CRITICAL APPRAISAL Sleep Bruxism and Sleep-Disordered Breathing Author STEVEN D BENDER, DDS*, Associate Editor EDWARD J. SWIFT JR., DMD, MS ABSTRACT Sleep bruxism (SB) is a repetitive jaw muscle activity with clenching or grinding of the teeth during sleep. SB is characterized by what is known as rhythmic masticatory muscle activity (RMMA). RMMA is the laboratory polysomnographic finding that differentiates SB from other oromandibular movements seen during sleep. Most often RMMA episodes are associated with sleep arousal. Some patients will report similar complaints related to both SB and sleep disordered breathing (SDB). There are some reports that would suggest that SB is a result of SDB. It has has been postulated that SB is a compensatory mechanism to re establish muscle tone of the upper airway. While these disorders do in fact often present concomitantly, the relationship between the two is yet to be fully elucidated. This Critical Appraisal reviews 3 recent publications with the intent to better define what relationships may exists between SDB and SB. While the current evidence appears to support the notion that these are often concomitant disorders, it also makes clear that evidence to support the hypothesis that SDB is causative for SB is currently lacking.

  • Sleep Apnea Sleep Apnea
    Health and Safety Guidelines 1 Sleep Apnea Sleep Apnea Normally while sleeping, air is moved at a regular rhythm through the throat and in and out the lungs. When someone has sleep apnea, air movement becomes decreased or stops altogether. Sleep apnea can affect long term health. Types of sleep apnea: 1. Obstructive sleep apnea (narrowing or closure of the throat during sleep) which is seen most commonly, and, 2. Central sleep apnea (the brain is causing a change in breathing control and rhythm) Obstructive sleep apnea (OSA) About 25% of all adults are at risk for sleep apnea of some degree. Men are more commonly affected than women. Other risk factors include: 1. Middle and older age 2. Being overweight 3. Having a small mouth and throat Down syndrome Because of soft tissue and skeletal alterations that lead to upper airway obstruction, people with Down syndrome have an increased risk of obstructive sleep apnea. Statistics show that obstructive sleep apnea occurs in at least 30 to 75% of people with Down syndrome, including those who are not obese. In over half of person’s with Down syndrome whose parents reported no sleep problems, sleep studies showed abnormal results. Sleep apnea causing lowered oxygen levels often contributes to mental impairment. How does obstructive sleep apnea occur? The throat is surrounded by muscles that are active controlling the airway during talking, swallowing and breathing. During sleep, these muscles are much less active. They can fall back into the throat, causing narrowing. In most people this doesn’t affect breathing. However in some the narrowing can cause snoring.

A mild form of sleepiness can be associated with reduced reactivity and modest distractibility symptoms, but more severe symptomatic forms are characterized by an overwhelming and uncontrollable need to sleep, causing sud- den sleep attacks, amnesia and automatic behaviors. The prevalence in the general population is between 10 and 25%. Furthermore, EDS has been considered a core symptom of obstructive sleep apnea (OSA), as well as being the main symptom of primary hypersomnias such as narcolepsy types 1 and 2, and idiopathic hypersomnia. Moreover, it can be considered secondary to other sleep disorders (Restless Legs Syndrome, Chronic insomnia, Periodic Limb Movements), psychiatric conditions (Depression, Bipolar Disorder) or a consequence of the intake/abuse of drugs and/or substances. An accurate medical history cannot be sufficient for the differential diagnosis, therefore instrumental recordings by means of polysomnography and the Multiple Sleep Latency Test (MSLT) are mandatory for a correct diagnosis and treatment of the underlying cause of EDS. RIASSUNTO «Sonnolenza diurna: più di una semplice Apnea Ostruttiva nel Sonno (OSA)». L’eccessiva sonnolenza diurna (Excessive Daytime Sleepiness, EDS) è una condizione molto comune con un impatto significativo sulla qualità di vita e sulla salute in generale.

  • Obstructive Sleep Apnea Obstructive Sleep Apnea (OSA) Is a Condition That Develops Due to Blockage of the Ability to Breathe During Sleep
    Snoring and Obstructive Sleep Apnea Obstructive sleep apnea (OSA) is a condition that develops due to blockage of the ability to breathe during sleep. Snoring is the most prevalent sign of sleep apnea, but it is not present in everyone with OSA. Patients with mild obstruction may not receive a diagnosis of OSA, but snoring may be a severe problem in those patients. When the obstruction is more sever, the patient may be diagnosed with OSA. Treatment is needed for OSA for several reasons. Symptoms of OSA include snoring, bedwetting (in children), morning headaches, high blood pressure, excessive sleepiness during the day. In general, the more severe the sleep apnea is, the worse the symptoms are. If you or your loved one tends to wake others up with their snoring, you should be evaluated. Evaluation of OSA is done by a test called a polysomnography, otherwise known as a sleep study. Basically, the patient goes to a sleep lab to spend a few hours sleeping. Monitors are attached to monitor breathing, loudness of snoring, oxygen levels in the blood, heart rate, and many other parameters. The results of the test are studied to see how severe the problem is. Treatment is needed for OSA for several reasons. Most immediately, it helps people feel better with less daytime sleepiness. This is especially important in those who operate heavy machinery, eg. truck drivers, crane operators, etc.. Furthermore, long term sleep apnea can result in heart problems, stroke, and uncontrolled hypertension. Treatment of OSA can help to prevent these problems. Treatment for this disorder can involve surgery, but the surgery is very painful and long term results can be disappointing.

A person with OSA has times during sleep in which air cannot flow normally into the lungs.

During the last 3 decades the prevalence of extreme obesity has markedly increased in the United States and other countries. With such a global epidemic of obesity, the prevalence of OHS is bound to increase. Patients with OHS have a lower quality of life, with increased healthcare expenses, and are at higher risk of developing pulmonary hypertension and early mortality, compared to eucapnic patients with sleep-disordered breathing. OHS often remains undiagnosed until late in the course of the disease. Early recognition is impor- tant, as these patients have significant morbidity and mortality. Effective treatment can lead to significant improvement in patient outcomes, underscoring the importance of early diagnosis. This review will include disease definition and epidemiology, clinical characteristics of the syndrome, pathophysiology, and morbidity and mortality associated with it. Lastly, treatment modalities will be discussed in detail.
