Itamar Medical Ltd. announced that it will collaborate with Henry Schein Inc.to develop Itamar’s WatchPAT apnea and sleep disorder diagnostic devices for use in dentistry in the US.
If the pilot of the product is successful to Henry Schein’s satisfaction, it will distribute the product to US dentists.

Henry Schein is a global distributor of dental products and services. Itamar cautioned that it cannot predict at this stage whether the pilot product will success, or if there will be any sales if it does, and whether any possible sales will have a material effect on the company.

Nasal continuous positive airway pressure (CPAP) can cause undesirable nasal symptoms such as congestion to obstructive sleep apnoea (OSA) patients, which symptoms can be attenuated by the addition of heated humidification.

However, neither the nature of nasal symptoms nor the effect of heated humidification on nasal pathophysiology and pathology are convincingly known.

 Twenty patients with OSA on nasal CPAP who exhibited symptomatic nasal obstruction were randomized to receive either 3 weeks of CPAP treatment with heated humidification or 3 weeks of CPAP treatment with sham-heated humidification, followed by 3 weeks of the opposite treatment, respectively.

 Patients with neuromuscular disease (NMD) are at risk of developing sleep-disordered breathing (SDB) following respiratory muscle involvement. The researchers hypothesised that a questionnaire based on clinical symptoms and signs of diaphragm weakness can be used to screen for SDB in such patients.  

Researchers developed a self-administered multiple choice questionnaire containing five questions (SiNQ-5), scoring 0–10 points. 125 patients were enroled, 32 with respiratory muscle weakness, 35 subjects with normal respiratory muscle strength, and 58 patients with obstructive sleep apnea (OSA). All subjects underwent full polysomnography. Read the rest of this entry

Obstructive sleep apnea has been related to increased cardiovascular risk. A recent research study examined the relationships between respiratory parameters and left ventricular abnormalities in obstructive sleep apnea.

One hundred and fifty newly diagnosed OSA patients without any known cardiovascular disease were included (age =49±11 years, BMI =27.1±3.3 kg·m–2, respiratory disturbance index =41±18/h). Haemodynamic, biological, respiratory, cardiac and arterial parameters were assessed at inclusion. Read the rest of this entry

Physiologic changes of pregnancy may predispose females to develop sleep disordered breathing (SDB) or protect against it. Studies evaluating outcomes of SDB symptoms in pregnancy are scarce. The goal of this study is to evaluate the prevalence of SDB symptoms in pregnancy and their relationship with pregnancy and neonatal outcomes.

A cross-sectional survey of randomly selected immediate postpartum females was performed using the multivariable apnea prediction index. Record review including demographics and medical history was performed. Main outcome measures included pregnancy and neonatal outcomes. Read the rest of this entry

Sleep related disorders (SRD) represent an important health burden and their prevalence increases with age.

In patients with snoring or sleepiness, the presence of expiratory flow limitation (EFL) using the Negative Expiratory Pressure (NEP) method is related to the Apnea/Hypopnea Index (AHI). In this study we examined whether EFL can be used to predict the obstructive sleep apnea syndrome (OSAS) in healthy asymptomatic older subjects. Read the rest of this entry

The researchers in Switzerland measured age-specific prevalence of airflow obstruction (AO) in Switzerland in smokers and never smokers using pulmonary function tests and respiratory symptoms from 6126 subjects participating in the Swiss Cohort Study on Air Pollution and Lung Diseases in Adults.

The lower limit of normal of FEV1/FVC ratio was used to define AO. Severity of AO was graded according to the recommendations of the Global Initiative for Chronic Obstructive Lung Disease. Read the rest of this entry

A research study was concluded recently to estimate the population prevalence of obstructive sleep apnea (OSA) in an urban community of German third graders and the diagnostic test accuracy of two OSA screening methods.

Using a cross-sectional study design with a multi-stage sampling strategy, 27 out of 59 primary schools within the city limits of Hannover, Germany, were selected. One-thousand and forty-four (1044)  third graders were screened for symptoms of Sleep Apnea along with Symptoms and signs of OSA using questionnaires and nocturnal home pulse oximetry.

To compare the sleep-disordered breathing prevalence among Hispanic and white Americans and Japanese, the researchers performed a one-night sleep study with a single channel airflow monitor on 211 Hispanics and 246 whites from the Minnesota Field Center of the Multi-Ethnic Study of Atherosclerosis (MESA), and 978 Japanese from three community-based cohorts of the Circulatory Risk in Communities Study (CIRCS) in Japan.

Sleep Apnea-A Monster That Attacks You in Sleep

One of the most common health disorders among people around the world is “sleep apnea”. In its simplest sense ‘sleep apnea’ can be understood as one or more pauses in normal breathing. In many cases the shallow breathing during sleep is also termed as ‘sleep apnea’.

A pause in normal breathing during sleep may have an undefined duration. Meaning thereby, the pause could be for a few seconds only or it can even stretch up to few minutes.

Similarly, the rate of occurrence of such pauses during sleep may also vary up to great ranges. It could be five times per hour or even up to 30 times an hour. Normal breathing generally starts immediately after such a pause but this re-start could generate a snoring or choking sound as well. Read the rest of this entry
