Mortality rates associated with oral cancer have remained unchanged for over 30 years, partly due to the limitations of white light examination of the oral mucosa. This has created a dire need for an improved oral mucosal screening procedure that would make it possible for clinicians to accurately identify tissue changes at and below the surface before they become apparent under white light examination.
In response to such a need, the Vancouver-based company LED Medical Diagnostics Inc. (LED-MD) has developed the VELscope System. It is a technology platform based on the direct visualization of human tissue fluorescence and the changes in fluorescence that occur when abnormal tissue is present.
The VELscope®System Handpiece emits a safe blue light
into the oral cavity, which excites the tissue from the surface of the epithelium through to the basement membrane and into the stroma beneath, causing it to fluoresce. We are then able to immediately view the different fluorescence responses to help differentiate between normal and abnormal tissue. In fact, the VELscope®System is the only adjunctive device cleared by the FDA and Health Canada to help discover oral mucosal lesions that might not be apparent or visible to the naked eye.
Under examination with the VELscope®System, abnormal tissue typically appears as an irregular, dark area that stands out against the otherwise normal, green fluorescence pattern of surrounding healthy tissue.
What Is Sleep ApneaBy Eric Cho
Sleep apnea is a disorder that prevents the body from getting a sufficient amount of oxygen during sleep. During times of sleep, the sleep apnea victim or patient literally stops breathing for small periods of time, creating an extremely dangerous situation. Over 12 million Americans have been diagnosed with sleep apnea and that figure includes women, men, and children though most of victims are older male adults. Sleep apnea is also known as obstructive sleep apnea and it’s the most common form. Throat blockage, mostly from the tongue or palate, is what gives obstructive sleep apnea its name - but it’s only one form. Two other forms are central sleep apnea and mixed sleep apnea.
CAUSES OF SLEEP APNEA
SLEEP APENEA TREATMENTThere are several causes, however tongue or palate blockage is the main culprit. Basically, anything that prevents the lungs from getting enough air to the brain is at fault, thus almost all breathing problems have been blamed. From smoking and asthma to being overweight to snoring, sleep apnea is now thought to play a role in developing diabetes, heart attacks, and even death.
Most treatments for sleep apnea involve the CPAP machine (continuous positive airway pressure). This machine works to supply the body (lungs and brain) with enough oxygen while the patient is sleeping. Some machines use nasal masks that cover the mouth and nose to send air, while others use a tube-connected mouth or nose piece to deliver air. The idea with either method is to keep the airway open so that a patient gets sufficient air through regular breathing.
Since the CPAP machine is a medical device, it requires a prescription from a neurologist and a polysomnogram (sleep study) examination.
Depending on the severity of the sleep apnea, a CPAP machine may not be needed. Some people have found relieve through natural methods simply by losing weight, cutting out certain foods from a diet, reducing alcohol consumption, or even avoiding certain medications under the doctor’s advice. Others have found help from the intake of specific vitamins and minerals.
The best supplements to ask us about are the ones that stimulate circulation, reduce cholesterol, regulate metabolism. Ingesting vitamins and minerals without professional medical advice can be dangerous however since a recent report disclosed that taking too many supplements (or the wrong ones) can cause problems rather than relieve them.
Under no circumstance, should a patient take a sleeping aid as a way to thwart sleep apnea. Sleeping aids are designed to deepen sleep, while sleep apnea treatments are designed to increase airflow. Both treatments solve completely different problems.
