The suck/swallow/breathe(SSB) synchrony, serving as the earlist primary motor mechanism, is the rhythmical, coordinated pattern of sucking, swallowing and breathing. The development of an intact SSB is an important precursor for further sensorimotor and cognitive development including speech and language development, state regulation, postural control, feeding, eye/hand coordination and social/emotional development. Arousal means a neurological mechanism for preparing one's body to orienting stimulus. Its levels are regulated with an interaction of the reticular formation, the limbic system, the hypothalamus and the autonomic nervous system. General strategies such as blowing, sucking, chewing, munching and licking to effectively modulate arousal state are related to SSB. The SSB synchrony is an important treatment principle for children with sensory integration disorder and problems with the modulation of arousal. The purpose of this article is to review concepts of SSB synchrony and the underlying relation between the modulation of arousal and SSB synchrony.

Objective : This is clinical about the Wei syndrome(痿證)-patient diagnosed as Guillian-Barre Syndrome(GBS). GBS, What is called acute inflammatory plolyneuritis, is a disorder in which the body's immune system attacks parts of peripheral nerve system. It is characterized by the rapid onset of weakness, paralysis of the legs, arms, breathing muscles and face. But the analysis of CSF and electical tests on nerve and muscle function can be performed to confirm the diagnosis. Most cases occur shortly after a viral infection. Methods & Result : This is the clinical report about the one patient diagnosed as Guillain-Barre Syndrome. The patient, 46-year-old men had weakness in both legs and arms after divertculitis. His weakness and general condition improved after oriental medical treatment and acupuncture. As a result, symptoms were improved remarkably. Conclusion : We report that we had good effects of oriental medical treatment on Guillain-Barre Syndrome.

Purpose: This study is a qualitative research to identify new nurses' adaptation experience to sleep changes. Method: Grounded theory methodology was utilized. Participants were 10 new nurses from one university hospital. The information was collected and analyzed using the grounded theory of Corbin and Strauss'(2008). Results: Through constant comparative analysis, central phenomenon was identified as 'Shaky daily life due to the sleep change'. A core category emerged as 'In the shaky daily life, go grab my position', Causal conditions were 'Heaviness in shift work', 'Not released after getting off work', and 'Body and mind are exhausted'. Context were 'An environment that does not tolerate mistakes' and 'Clogged breathing due to worries'. Intervening factors were 'Support of colleagues', 'Recovery volition in restoration of altered relationships due to sleep'. Action/Interaction Strategies were 'To strive for a good sleep', 'Require a reasonable duty schedule' and 'Find a breakthrough'. Consequences were 'Become the master of shaky daily life' and 'Accepting the life of a nurse'. Conclusion: New nurses experience sleep patterns changes from the hospital shift system. but throughout the process of adaptation, came to accept sleep disorder as part of the life of a nurse.

In this paper, we propose a sleep efficiency measurement algorithm based on IR-UWB radar sensor in distance. Among the vital signs which can be measured by the IR-UWB radar sensor such as breathing rate, heartbeat rate, and movement, we analyzed correlation between the movement and the sleep efficiency, and based on the result, we propose a sleep efficiency measurement algorithm. In order to verify the performance of the proposed algorithm, we applied the algorithm to three polysomnography patients in hospitals and obtained the performance of an average absolute error within 3.9%.

Obstructive sleep apnea (OSA) is a relatively common, but greatly underdiagnosed sleep-related breathing disorder, characterized by recurrent collapse of the upper airway during sleep. OSA has been associated with a variety of cardiometabolic disease, such as hypertension, coronary artery disease, cardiac arrhythmia, cerebrovascular disease and metabolic dysfunction. Neurocognitive impairment, including excessive daytime sleepiness, increased risk of motor vehicle accidents, is also related to OSA. Sleep fragmentation and related arousals during sleep lead to intermittent hypoxia, sympathetic activation, oxidative stress, systemic inflammation and metabolic dysregulation which provide biological plausibility to this pathologic mechanism. Extensive studies demonstrated that OSA is a modifiable risk factor for the above mentioned diseases and oral appliances (OAs), although continuous positive air pressure (CPAP) is a first-line therapy of OSA, are not inferior to CPAP at least in mild OSA, and may be an alternative to CPAP in CPAP-intolerant subjects with OSA. The goal of this article is to provide a current knowledge of pathologic link between OSA and cardiovascular disease, focusing on intermittent hypoxia, sympathetic activation, oxidative stress and metabolic dysregulation. Then, previous epidemiologic studies will be reviewed to understand the causal relationship between OSA and cardiovascular disease. Finally, the effects of OAs will be updated via recent metaanalyses compared to CPAP.

Menopause, the cessation of menstruation caused by the decline in estrogen production, occurs in 95% of women between 40 and 60 years. Sleep disturbance is a frequent complaint during the perimenopause period. In contrast to premenopausla women, menopausal women experience more reduction in the total sleep hours and report more sleep disturbances, such as insomnia, noctiria and sleep disordered breathing. But the prevalence, etiology and treatment of sleep disturbances in menopause are still controversal. So further investigations are required to elucidate the factors that account for the differences in sleep disturbance between premenopausal and postmenopausal women. There are suggestive data that estrogen and progesterone deficiency may increase the susceptibility for sleep disorder in menopause. Furthermore, there are suggestive evidence from observational studies and a limited number of randomized, controlled trials that hormone replacement therapy after menopause improves sleep. However, the clinical relevance of hormone replacement therapy is unproved. So the overall benefit of hormonal replacement in postmenopausal women with sleep related disorders should be individualized to avoid potential side effects. Several studies evaluated the role of melatonin, because this hormone has effects on core body temperature & insomnia. But the exact dosage and the effects of long-term use of melatonin are unclear. So, caution is indicated in melatonin administration.

Difficulty in breathing can be very disconcerting to a patient who is conscious yet unable to breath normally. The common causes of acute respiratory distress include hyperventilation, vasodepressor syncope, asthma, heart failure, and hypoglycemia. In most of these situations, the patient does not exhibit respiratory distress unless an underlying medical disorder becomes acutely exacerbated. Examples of this include acute myocardial infarction, anaphylaxis, cerebrovascular accident, hyperglycemia, and hypoglycemia. A major factor that leads to the exacerbation of respiratory disorders is undue stress, either physiologic or psychologic. Psychologic stress in dentistry is the primary factor in the exacerbation of preexisting medical problems. Therefore, the most dental patient should be cared gently as the stress reduction protocol. This is a case report of acute respiratory distress with vasodepressor syncope during alginate impression taking of mandibular teeth in a long-standing temporomandibular joint dislocated 93-years-old pneumonic patient.

Evaluating the patient's voice before thyroidectomy is useful for the purpose of identifying patients with vocal cord paralysis without symptoms, identifying other patient's voice abnormalities, and whether it is related to voice disorders that may occur after surgery. Also voice evaluation after thyroid surgery is helpful in diagnosis, treatment, and rehabilitation and follow-up of voice disorders that occur without clear nerve damage after thyroidectomy. And it is helpful for rapid recovery through active early rehabilitation treatment for patients who complain of speech impairment without paralysis. In particular, neck exercise can improve the adhesion of the surgical site and increase the range of motion of the neck as well as improve subjective neck discomfort. In addition, hearing, voice and breathing functions should be improved, and voice hygiene education and counseling should be provided. Vocal cord injection is the first treatment option for unilateral vocal cord palsy. By establishing a protocol for voice disorders before and after thyroid surgery and providing appropriate treatment, the quality of life of patients can be improved.

Obstructive sleep apnea (OSA) is a common sleep-breathing disorder associated with significant comorbidities and perioperative complications. This narrative review is aimed at comprehensively overviewing preoperative risk evaluation and perioperative management strategies for patients with OSA. OSA is characterized by recurrent episodes of upper airway obstruction during sleep leading to hypoxemia and arousal. Anatomical features, such as upper airway narrowing and obesity, contribute to the development of OSA. OSA can be diagnosed based on polysomnography findings, and positive airway pressure therapy is the mainstay of treatment. However, alternative therapies, such as oral appliances or upper airway surgery, can be considered for patients with intolerance. Patients with OSA face perioperative challenges due to difficult airway management, comorbidities, and effects of sedatives and analgesics. Anatomical changes, reduced upper airway muscle tone, and obesity increase the risks of airway obstruction, and difficulties in intubation and mask ventilation. OSA-related comorbidities, such as cardiovascular and respiratory disorders, further increase perioperative risks. Sedatives and opioids can exacerbate respiratory depression and compromise airway patency. Therefore, careful consideration of alternative pain management options is necessary. Although the association between OSA and postoperative mortality remains controversial, concerns exist regarding adverse outcomes in patients with OSA. Understanding the pathophysiology of OSA, implementing appropriate preoperative evaluations, and tailoring perioperative management strategies are vital to ensure patient safety and optimize surgical outcomes.

Sleep apnea (SA) is a common chronic sleep disorder that disrupts breathing during sleep. Clinically, the standard for diagnosing SA involves nocturnal polysomnography (PSG). However, this requires expert human intervention and considerable time, which limits the availability of SA diagnoses in public health sectors. Therefore, ECG-based methods for SA detection have been proposed to automate the PSG procedure and reduce its discomfort. We propose a preprocessing method to convert the one-dimensional time series of ECG into two-dimensional images using the Gramian Angular Field (GAF) algorithm, extract temporal features, and use a two-dimensional convolutional neural network for classification. The results of this study demonstrated that the proposed method can perform SA detection with specificity, sensitivity, accuracy, and area under the curve (AUC) of 88.89%, 81.50%, 86.11%, and 0.85, respectively. Our experimental results show that SA is successfully classified by extracting preprocessing transforms with temporal features.
