Surgical Management of Obstructive Sleep Apnea Syndrome
Min, Yang-Gi ; Rhee, Chae-Seo ;
Sleep Medicine and Psychophysiology, volume 1, issue 2, 1994, Pages 117~124
Obstructive Sleep Apnea Syndrome(OSAS), that is a complex disease of neuromuscular, respiratory and cardiovascular system, can be cured by various treatment such as weight control, medical and surgical intervention. As most of OSAS may be caused by various anatomical abnormalities, preoperative evaluation for exact anatomical site of obstruction must be needed. And various diagnostic procedures such as fiberoptic nasopharyngoscopy, Mueller test, cinefluoroscopy, cephalometry, computerized tomography, polysomnography would be used for this purpose. Uvulopalotopharyngplasty is currently the most popular method for the patient with OSAS among various surgical maneuvers and is very effective for the relieving the symptoms as like snoring, daytime somnolence, and nocturnal restlessness etc. Although subjective improvement is not compatible with it's objective assessment in postoperative evaluation for it's results, uvulopalatopharyngoplasty could be a recommandable surgical procedure because of it's ample effectiveness in promoting symptom improvement without any risk of serious complications.
Usefulness of Various Questionnaires in the Assessment of Excessive Daytime Sleepiness and Circadian Rhythm
Kim, Moo-Jin ;
Sleep Medicine and Psychophysiology, volume 1, issue 2, 1994, Pages 125~144
Recently excessive daytime sleepiness was found to have relations with various social, occupational, and health problems. This condition is common symptom of several sleep disorders, among which sleep apnea syndrome is most contributive. It is essential to assess daytime sleepiness exactly for the diagnosis of such sleep disorders. Multiple sleep latency test which is a valid and objective measurement technique of sleepiness is time and cost consuming, and so there is increasing need of scales measuring general level of daytime sleepiness which are quick and simple to perform for clinical and research purpose. And also, there have been a lot of sleep researches viewing sleep as a chronobiological process, especially in the study of circadian type of shift workers. In these studies they used various techniques of multiple demensions to assess sleepiness or circadian rhythm which concerns various psychological variables. Of these measurement techniques circadian type questionnaires might have some problems in their psychometric properties. So some of these morningness-eveningness questionnaires have been revised and more valid scales are being suggested by different authors. The author briefly reviewed various measurement techniques of sleepiness and circadian rhythm and introduced recently developed scales which are more valid allegedly, and finally discussed psychometric properties of these morningness-eveningness questionnaires.
Techniques for the Neurophysiological Experiments of Brain and Behavior
Cheon, Jin-Sook ;
Sleep Medicine and Psychophysiology, volume 1, issue 2, 1994, Pages 145~155
The neurophysiological study has been widely used in the search of the relation between brain and behavior. The basic techniques for the animal experiments of this kind such as stereotaxic techniques, lesioning methods, the methods of electrical stimulation and confirmation of histological location were simply reviewed. Nevertheless, the importance of complementary neurochemical, neuroanatomical and behavioral studies can not be neglected.
Eyeblinks, EP Augmenting / Reducing and Personality
Lee, Sung-Hoon ; Haier, Richard J. ;
Sleep Medicine and Psychophysiology, volume 1, issue 2, 1994, Pages 156~162
Objectives: Eyeblinking varied depending on individual cognitive abilities or personality traits thought to related to brain mechanisms of sensory modulation. This study explored whether personality traits are related to the rate of eye blinks and how eyeblink and evoked potential augumenting-reducing(EPAR) interact Methods: Forty four students were studied with EPAR topography to explore how eyeblinks, personality and EPAR interact The Zuckerman Sensation Seeking Scale(SSS) and Eysenck Personality Questionnaire(EPQ) were used as personality measured by a stimulus response program during EP study. Results: Rate of blink increased as intensity of light increased. The General(GEN), Thrill and Adventure Seeking(TAS), Experience Seeking(ES) and Disinhibition(DS) subscales in SSS and Extraversion-Introversion(E) subscale in EPQ showed significant negative correlations with number of eyeblinks in the hightest intensity of light, whereas Neuroticism(N) subscales in EPQ showed a positive correlation. Correlation between number of eyeblinks with the brightest light and EPAR slope varied topographically. The strongest positive correlation was noted in right posterior temporal area. Conclusion: High sensation seekers blinked significantly fewer times than lower sensation seeker did. Higher personality correlations with eyeblink than with EP may imply that the eyeblink works as a primary filter since it is more directly related to central mechanisms of sensory modulation than EP. The right posterior temporal area may play an important role in modulation of visual stimuli.
Correlations between Symptoms of Sleep Apnea and Respiration during Sleep
Lee, Sung-Hoon ; Lee, Hee-Sang ;
Sleep Medicine and Psychophysiology, volume 1, issue 2, 1994, Pages 163~171
Objectives: Symptoms of sleep apnea consisted of insomnia, excessive sleepiness during daytime, impaired cognitive functions and emotional disturbances. It was not so well known how these symptoms are correlated with various parameters of sleep and respiration, and what kind of psychophysiological processes are involved in development of these symptoms. Methods: In sixty patients with sleep apnea, sleep and respiration were studied by polysomnography of one night, also symptoms of sleep apnea were evaluated with the scales of insomnia, daytime sleepiness, emotional disturbance and cognitive impairment We studied correlations between apnea symptoms, and various parameters of sleep and respiration such as sleep efficiency, number severity of apnea,
desaturation and number of snoring. Results: The result showing significant correlations are as follows. The patients with better sleep in insomnia scale showed more number of apnea, particularly more central type, and much more snoring in stage 3 sleep and mild desaturation of
. Excessive sleepiness during daytime correlated significantly with stage 1 sleep and its snoring, but correlated negatively with stage 2 sleep. However, no significant correlation was found with degree of
desaturation. Emotional disturbance was more apparent in the patients with severe
desaturation and smaller amounts of stage 4 sleep. Cognitive function was more impaired in cases of more REM sleep and less apnea. Conclusions: Symptoms of sleep apnea may occur through different causes and processes. The evaluation of apnea symptoms may be helpful to understand in some degree the condition of sleep and respiration during sleep in clinical setting.
Therapeutic Change of Sleep Structure and Function by Continuous Positive Airway Pressure Application in Obstructive Sleep Apnea Syndrome
Jeong, Do-Un ; Yoon, In-Young ; Shim, Young-Soo ;
Sleep Medicine and Psychophysiology, volume 1, issue 2, 1994, Pages 172~181
Obstructive sleep apnea syndrome(OSAS) is most frequently diagnosed in the sleep laboratories and its severity is objectively estimated. In terms of treatment, the most prevalent method is the continuous positive airway pressure(CPAP) application as of now. However, in Korea, CPAP is still not sufficiently known and it is attributable to the fact that sleep study facilities have not been popularized. In this article, the authors present their own experience with CPAP in nine subjects with OSAS. In this study, CPAP was found to decrease stage 1 sleep and to increase stage 2 sleep, with increasing mean oxygen saturation and decreasing lowest oxygen saturation during nocturnal sleep. Also, it tended to increase sleep continuity and generally to improve sleep architecture. Rebound slow wave and/or REM sleep stages during CPAP were also noted in 8 out of 9 cases. The authors suggest that CPAP should be considered as the primary mode of treatment for patients with obstructive sleep apnea syndrome and related educational programs for physicians should be developed and provided by sleep specialists.
A Case of Sleep Paralysis Associated with Hyperventilation
Suh, Kwang-Yoon ; Kim, Leen ; Lee, Seung-Hwan ;
Sleep Medicine and Psychophysiology, volume 1, issue 2, 1994, Pages 182~187
The Authors report a case of sleep paralysis patient who is 25-years old man. He complained that he has been experiencing episode "being suffocated" during sleep and could not move by himself while semiconsciousness state. He was a only son of divorced parents and could not attach anybody from yong childhood. His symptoms was began intermittently after his early teens. Medical history and physical examination revealed no significant finding. A nocturnal polysomnogram showed loss of muscle tone during terminal REM period and sudden hyperventilation attack followed by wake-up. Psychosocial stress and insufficient sleep were presumed to be an etiological factors. Imipramine 50mg per day almost completely relieved symptoms.
Trial of Light Therapy on a Woman with LLPDD : A Case Report
Joe, Sook-Haeng ;
Sleep Medicine and Psychophysiology, volume 1, issue 2, 1994, Pages 188~192
The author reports a 32 years old female patient with late luteal phase dysphoric disorder who received evening bright light treatment for 7 consecutive days during the late luteal phase of menstrual cycle. After the treatment, beneficial clinical effects were observed. This result suggests that bright light can be an alternative treatment for LLPDD. However, the placebo effects should be ruled out completely. Further controlled studies with more patients will be needed.
Utility of Brain SPECT in Diagnosis of Elderly Depressed Patient
Kim, Young-Chul ;
Sleep Medicine and Psychophysiology, volume 1, issue 2, 1994, Pages 193~196
Primary depression with cognitive impairment, referred to as depressive pseudodementia, may be mistaken for a progressive degenerative dementia. Recognition of primary depression is clinically important because of its treatability. To differentiate depression from degenerative dementia, author used brain SPECT. By the result the regional cerebral blood flow(rCBF) in elderly depressed patient was decreased in the right frontal cortex. The pattern of rCBF was different from that of dementia which shows decreased rCBF in bifrontal cortex. By using brain SPECT in depressed elderly patient with cognitive impairment, the discrimination from dementia will be more effective and accurate.
