Background: Pregnancy is associated with a number of physical, emotional, and biological changes that can exacerbate maternal psychological disturbances, such as body image concerns and depression. Sleep disturbances during pregnancy can also have adverse impacts. This study aimed to determine the prevalence of depression, sleep disturbances, and body image concerns among pregnant women. The study also examined the relationship between these factors and pregnancy-related variables, such as bad obstetric history and whether the pregnancies were unplanned. Methods: A cross-sectional study of 146 pregnant patients was conducted at a tertiary care center over 15 months. The patients were administered the Beck Depression Inventory, Pittsburgh Sleep Quality Index, and Body Image Concern Inventory questionnaires. Contingency tables, Fisher exact test, and Spearman correlation were used to identify underlying relationships. Results: The prevalence of depression was 22.6%. Although body image disturbance was noted in only 2.7% of patients, 46.6% had poor sleep quality. Poor sleep was associated with primigravida status. Bad obstetric history and unplanned pregnancy were associated with depression. Depression was found to be significantly correlated with body image disturbances and poor sleep quality. Conclusion: Psychiatric disorders were prevalent during pregnancy. This study highlights the importance of screening for depression in pregnant patients. Counselling and caregiver education can be useful for mitigating psychological disturbances. Management of pregnancies by multidisciplinary teams that include psychiatrists could be immensely useful in improving the pregnancy experiences of patients.

In this study, we present the surgical treatment of obstructive sleep apnea in a child with Treacher Collins syndrome. A 10-year-old girl with a past history of Treacher Collins syndrome presented to our clinic with her parents for respiratory distress and insomnia. The patient was referred to a sleep laboratory where she was diagnosed with obstructive sleep apnea, which was a consequence of her Treacher Collins syndrome. The patient underwent mandibular distraction osteogenesis under general anesthesia. The mandible was expanded by 15 mm using internal bilateral distractors. After distraction osteogenesis, the patient's respiratory problems resolved, and she was able to sleep comfortably. Distraction osteogenesis was an effective method of advancing the mandible, increasing the upper airway space and ultimately preventing obstructive sleep apnea syndrome in patients with Treacher Collins syndrome.

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.

The authors report a case of REM sleep behavior disorder which occurred in a 69-year-old business man. He began experiencing episodic "acting out" behavior of his dream at the age of 66. The episodes tended to be associated with dream contents, mainly being chased or threatened. Before that, his sleep was relatively quiet despite occasional nightmares, midsleep arousal, and shallowness. Injuries resulted from leaping out of bed, jumping onto furnitures, and grabbing and biting the spouse's arm. Most recent dream-incurred laceration of chin required 5 sutures. Medical and psychiatric history revealed no significant findings except that he had been overanxious all his life within himself with others' reputation of himself as pleasant and easy-going. A nocturnal polysomnogram showed repeatedly intermittent increase of chin and/or leg muscle tones during otherwise characteristic REM sleep period. The overnight video recording revealed head lifting and limb movements during REM sleep periods. Brain MRI and EEG were normal. Job-related stress was presumed to be an etiological possibility. Clonazepam 0.25-0.5mg nightly almost completely relieved the symptoms.

운동이 수면에 미치는 효과를 보다 명확하게 검증하기 위해 일반상태가 아닌 카페인으로 인한 수면장애 상태에서 운동의 효과를 조사하였다. 본 연구의 피험자는 3회의 실험 조건(1. 평상시, 2. 카페인 섭취, 3. 카페인섭취 $\times$운동)에 참여해서 이들의 수면변수와 수면시 뇌파를 측정하였다. 카페인은 고용량으로 1200mg(400mg$\times$3)을 투여하였으며, 운동강도는 60% V $O_{2peak}$에서 60분을 사이클 에르고미터를 이용해 실시하였다. 본 실험결과 카페인 섭취로 입면시간 연장과 수면효율성 감소 그리고 서파수면(SWS)의 감소로 수면에 불리한 효과를 유발시켰다. 하지만 카페인 섭취와 운동을 병행했을 때 카페인 투여시 발생된 효과를 상쇄시키는 효과가 나타났다. 이러한 결과로써 고용량의 카페인 섭취가 수면장애 유발 효과가 있었지만 운동을 병행해서 실시했을 때 수면촉진과 수면효율성 그리고 숙면인 서파수면의 증가가 나타남으로써 운동이 수면방해를 완화시키고 수면 향상에 효과가 있는 것으로 생각된다.

Enuresis nocturia is more prevalent in children than in adults. Using polysomnography (PSG), we investigated the causes of adult enuresis nocturia in a 20-year-old female patient with nighttime bedwetting. In spite of normal urological examinations, her detailed medical history disclosed frequent sleep paralysis and urination during dreams. During PSG, two electromyograms were attached to her anus to assess the tone of her bladder's sphincter while she slept. During REM sleep, the EMG tone of the mandible decreased, but the anal and bladder sphincter tones did not. The polysomnogram revealed moderate obstructive sleep apnea. Consequently, she was diagnosed with adult parasomnia (nocturnal enuresis) overlap syndrome with OSA. This study demonstrates the value of PSG with simultaneous anal tone EMG for diagnosing NREM parasomnia and nocturnal enuresis.

The authors studied 5 cases of idiopathic CNS hypersomnia who visited Division of Sleep Studies, Seoul National University Hospital in 1995. Detailed medical history was taken and nocturnal polysomnography(NPSG), multiple sleep latency test(MSLT) and human leukocyte antigen(HLA) typing were performed. Neither cataplexy nor hypnagogic hallucination was reported in all cases and in NPSGs, there were tendencies of increased sleep period time and decreased slow wave sleep time. In MSLT, all the subjects showed average sleep latencies less than 8 minutes without sleep-onset rapid eye movement period(SOREMP). In HLA typing, some correlation between idiopathic CNS hypersomnia and HLA DR4 was observed. In contrast to previous reports, overall treatment response with methylphenidate was remarkable. Therefore, the authors suggest that patients suspected of idiopathic CNS hypersomnia be actively evaluated and treated with rather optimistic perspective.

목 적 : 십년 이상 각성장애를 보인 20세 남자환자를 분석하였다. 환자는 두통, 만성피로, 경한 주간졸리움증을 호소하였으나 조절할 수 없는 수면발작, 탈력발작, 입면시 환각이나 수면마비의 병력은 없었다. 방 법 : 야간 수면다원검사 (PSG), 반복적 수면잠복기 검사 (MSLT) 및 조직적합성 유전자검사 (HLA-typing)를 시행 하였다. 결 과 : PSG상 수면잠복기가 짧고 (4분), 렘수면잠복기도 감소하였고 (2.5분), 각성지표 (arousal index)가 시간당 15.7로 약간 증가되었으며, 수면 중 주기적 사지운동지표 (PLMS index)가 시간당 8.1로 관찰되었으나 운동과 연관된 각성지표 (movement arousal index)는 시간당 2.1로 높지 않았다. 잠효율은 (sleep efficiency)는 97.5%로 정상이었다. MSLT상 수면잠복기는 15분 21초로 정상이었으나 sleep-onset REM (SOREM)은 5회의 낮잠 시도 중 4회에서 관찰되었다. HLA-typing에서 DQ6-양성이었는데, 이는 기면증 환자에서 대개 관찰되는 유전자 위치인 DQB1*0602, DQA1*0102와는 다른 DQB1*0601 부위에 상응하였다. 결 론 : 일차성 각성장애의 원인이 되는 여러 질환 특히 일주기리듬장애나 기면증, 원발성 다면증과의 감별진단이 필요하며, 수면검사와 유전자검사 상 기면증의 새로운 변종일 가능성을 배제할 수 없다.

In all ages and countries, dreaming has always been a topic that has interested people. Throughout history, theories about dreaming have been heavily dependent on concurrent theories in related domains. Many researchers have claimed that dreaming occurs during REM and NREM sleep and have rejected the strict association between REM sleep mechanisms and dreams. Although dreams may occur in both REM and NREM periods, they are likely to be produced by different mechanisms during REM and NREM sleep. All physicians managing dreaming-related problems in clinical practice need to understand the multidimensional aspects of dreaming. Therefore, I have reviewed the literature on mechanisms generating and the meaning of dreaming in the neurobiological and psychophysiological perspectives.

Purpose: This study was performed to evaluate the quality of sleep in snoring obese children without obstructive sleep apnea (OSA); and to study the possible relationship between sleep interruption and gastroesophageal reflux (GER) in snoring obese children. Methods: Study subjects included 13 snoring obese children who were referred to our sleep lab for possible sleep-disordered breathing. Patients underwent multichannel intraluminal impedance and esophageal pH monitoring with simultaneous polysomnography. Exclusion criteria included history of fundoplication, cystic fibrosis, and infants under the age of 2 years. Significant association between arousals and awakenings with previous reflux were defined by symptom-association probability using 2-minute intervals. Results: Sleep efficiency ranged from 67-97% (median 81%). A total of 111 reflux episodes (90% acidic) were detected during sleep, but there were more episodes per hour during awake periods after sleep onset than during sleep (median 2.3 vs. 0.6, p=0.04). There were 279 total awakenings during the sleep study; 56 (20.1%) of them in 9 patients (69.2%) were preceded by reflux episodes (55 acid, 1 non-acid). In 5 patients (38.5%), awakenings were significantly associated with reflux. Conclusion: The data suggest that acid GER causes sleep interruptions in obese children who have symptoms of snoring or restless sleep and without evidence of OSA.
