The symptoms of restless legs syndrome usually involve legs, but can extend to other body parts. However, isolated body parts other than the leg are rarely involved. A 36-year-old woman presented for evaluation with a tingling and burning sensation in the both hands for one year. These abnormal sensations appeared in the evening and night, resulting in difficulty in falling asleep. The symptoms were relieved by shaking and bending of hands and wrists. Pramipexole was increased to 0.375 mg, and 75 mg of pregabalin was added, but her abnormal nocturnal sensation was not improved. Overt hyperthyroidism was revealed by thyroid function test: free thyroxin 2.99 ng/dL and thyroid-stimulating hormone 0.009 µIU/mL. One month later, her symptom showed much improvement after taking methimazole 5 mg twice a day. We report a case of abnormal nocturnal sensation of hands in the patient with hyperthyroidism who responded with methimazole.

Sleep-related laryngospasm is a rare cause of sleep-related breathing disturbance which produce stridor or interruption of airflow associated with a distinct polysomnography arousal pattern. We report a case of a sixty-five-year-old woman who was referred for awakenings with abrupt respiratory distress and fear of suffocation. A polysomnography showed a total or near-total cessation of airflow, followed by choking and stridor for several minutes with a rapid increase in heart rate. Temporary hoarseness was seen. The esophageal pH monitoring indicated acid reflux, which confirmed gastroesophageal reflux disease. The protonpump inhibitor eliminated the sleep-related laryngospasm.

Jeonghwa LEE ; Sooyeon SUH

Journal of Sleep Medicine.2016;13(1):21-27. doi:10.13078/jsm.16004

OBJECTIVES: The current study aimed to investigate individuals with night eating syndrome tendency in 115 female undergraduate sample based on night eating syndrome criteria, and analyze its association between mood, sleep, and alcohol use. METHODS: Subjects were divided into high and low tendency group of night eating syndrome based on the night eating questionnaire. All participants completed the Hospital Anxiety and Depression Scale, Insomnia Severity Index, Munich Chronotype Questionnaire, and Alcohol-Use Disorders Identification Test. Data was collected at two time points which were 3 months apart. All analyses were conducted using repeated measure ANOVA. RESULTS: Results indicated a significant difference between night eating syndrome tendency groups for anxiety and depression [F(1,113)=12.35, p=0.001 and F(1,113)=9.59, p=0.002, respectively]. Depression also had a significant time effect [F(1,113)=11.15, p=0.001]. Additionally, the high night eating syndrome tendency group had higher levels of insomnia severity [F(1,113)=24.34, p<0.001], eveningness [F(1,113)=15.09, p<0.001], and alcohol use [F(1,113)=6.73, p=0.011], and lower sleep efficiency [F(1,113)=6.30, p=0.014] compared to the low night eating syndrome tendency group. CONCLUSIONS: The high night eating syndrome tendency group had higher negative mood, sleep disturbance, and alcohol use compared to the low night eating syndrome tendency group. In summary, intervention for night eating syndrome may be important to consider in undergraduate students.

The Utility of the McGill Overnight Oximetry Score for the Moderate to Severe Obstructive Sleep Apnea Syndrome in Korean Children.

Seung Soo KIM ; Kwang Ik YANG

Journal of Sleep Medicine.2016;13(1):15-20. doi:10.13078/jsm.16003

OBJECTIVES: We conducted this study to evaluate the utility of the McGill oximetry score (MOS) to rule out moderate to severe obstructive sleep apnea syndrome (OSAS) in Korean children. METHODS: We performed a cross-sectional study by using medical and polysomnography (PSG) records from our sleep disorder center. We assessed 58 PSG records conducted from September 2011 to December 2015. MOS was calculated from the overnight oximetry tests performed as part of PSG. We also investigated age, gender, height z-score, weight z-score, body mass index z-score, obesity, underweight, and pediatric daytime sleepiness scale. RESULTS: MOS revealed inconclusive (score 1) in 50 (68.2%), and abnormal (2-4) in 8 (13.8%) of PSG results. And moderate to severe OSAS were diagnosed in 20 (34.5%) records according to the apnea-hyponea index (≥5). In a multivariate logistic regression analysis, age [adjust odds ratio (OR) 0.8; p-value=0.013] and abnormal MOS (adjust OR 39.5; p-value=0.007) showed statistical significance between normal/mild OSAS group and moderate/severe OSAS group. MOS had a positive predictive value of 88%, a negative predictive value of 74%, a sensitivity of 35% and a specificity of 97% for detecting moderate/severe OSAS. CONCLUSIONS: In our small group study, MOS cannot exclude moderate to severe OSAS. Further prospective studies are needed.

Light Exposure and Sleep-Wake Pattern in Rapidly Rotating Shift Nurses.

Su Jung CHOI ; Eun Yeon JOO

Journal of Sleep Medicine.2016;13(1):8-14. doi:10.13078/jsm.16002

OBJECTIVES: Shift workers are at risk for various sleep and health-related problems. To investigate light exposure and sleep-wake pattern according to shift schedules in shift workers. METHODS: We enrolled 12 full-time, rapidly rotating three-shift female nurses (age 26.4±4.01 years). They completed sleep logs and actigraphy monitoring of sleep-wake parameters, light exposure, and activity levels for over 14 days (mean numbers of night shifts 2.5). RESULTS: Before beginning shift work, participants were healthy and had no history of hypnotics. One third of participants (33.3%) had clinically significant insomnia-related symptoms (insomnia severity index ≥15, mean 14.0). Reported health problems were irregular menstruation cycles (75%), nightmares (25%), and irritable bowel syndrome (16.7%). Mean sleep time was less than 6 h regardless of the shift periods and wakefulness after sleep onset was prolonged more than 30 min. Light exposure in night-shift periods was the lowest during working hours and the highest during non-working hours. Activity levels were not different during working hours throughout the schedules. CONCLUSIONS: Fast-rotating shift nurses sleep less and unsatisfactorily. Health-related problems were frequent in shift nurses. Rapidly rotating shift schedules and related inappropriate light exposure may be detrimental to sleep and health in shift workers.

Optimizing the Pharmacological Treatment for Insomnia.

Seockhoon CHUNG ; Soyoung YOUN

Journal of Sleep Medicine.2016;13(1):1-7. doi:10.13078/jsm.16001

The Cognitive-Behavioral Therapy for Insomnia (CBT-I) is an important and effective treatment for insomnia patients. However, it is not easy for most general practitioners to learn and practice CBT-I, and it is popular to prescribe sleeping pills to insomnia patients in clinical practice. In the case, we need to consider the factors which can influence the effect of sleeping pills to prescribe sleeping pills appropriately and safely with the lowest dosage. Age, gender, medical or psychiatric comorbid disease, workplace, or sleep environment may affect the patients' satisfaction with their sleeping pills. Physician should know about the mechanism of action of each sleeping pill and which type of sleeping pills needs to be prescribed to patients in each situation. Physician also needs to ask patients what time they took their sleeping pills and check whether patients followed physician's sleeping pills administration instruction or not. In this review, we want to discuss about optimizing the sleeping pills prescription to insomnia patients.

Sleepwalking Triggered by Hypoglycemia.

Sun Jung HAN ; Jee Hyun KIM

Journal of Sleep Medicine.2015;12(2):67-70. doi:10.13078/jsm.15013

Sleepwalking is a rare parasomnia in the elderly. We report two cases of the patients who presented complex motor behaviors during sleep triggered by hypoglycemia. A 76-year-old male patient with diabetes mellitus presented to the sleep clinic for recurrent sleepwalking with amnesia. Night polysomnogram showed REM sleep without atonia with sleep talking and distal arm movements. While taking clonazepam, he had a few more episodes of sleepwalking. The last episode finally revealed severe hypoglycemia when he was found very far from his house. The second patient, a 67-year-old male showed four episodes of nocturnal confusion and sleepwalking lasting 20 minutes during sleep. His blood glucose and HbA1c were low. After decrease of the dose of oral hypoglycemic agent, no more recurrent sleepwalking occurred. Our cases showed hypoglycemia can induce sleepwalking in the older adults, rather than decreased mentality. Metabolic workup should perform for evaluation of sleepwalking, especially in the elderly.

Cheol Won JANG ; Ki Hwan JI

Journal of Sleep Medicine.2015;12(2):64-66. doi:10.13078/jsm.15012

A condition of underestimation of sleep is classified as paradoxical insomnia or sleep state misperception. However, overestimation of sleep, so called positive sleep state misperception has not been clearly described. Here we report a middle-aged woman with positive sleep state misperception who presented excessive sleepiness mimicking hypersomnia.

Journal of Sleep Medicine.2015;12(2):59-63. doi:10.13078/jsm.15011

OBJECTIVES: Obstructive sleep apnea-hypopnea syndrome (OSAHS) and insomnia are two of the most common sleep disorders in the general population. Because OSAHS patients with insomnia may have difficulty in adapting to the sleep breathing medical equipment, it is necessary to pay special attention to the diagnosis and treatment of comorbid insomnia. This study is to investigate the emotion and personality in OSAHS patients with insomnia complaints by using Minnesota Multiphasic Personality Inventory-2 (MMPI-2). METHODS: We reviewed the results of the standardized questionnaires assessing sleep-related variables, MMPI, and polysomnographic findings of the patients diagnosed as OSAHS. RESULTS: 145 subjects were 49.05+/-11.83 years of age. The mean Respiratory Disturbance Index was 33.57+/-19.91 and the mean score of Insomnia Severity Index (ISI) was 11.52+/-6.49. The mean scores of the Beck Depression Inventory (BDI) and MMPI-2 were within normal ranges. We divided the patients into two groups based on the scores of the ISI, OSAHS with insomnia (n=109) and OSAHS without insomnia (n=36). OSAHS patients with insomnia symptoms had significantly higher scores of hypochondriasis, hysteria, psychasthenia, schizophrenia, paranoia and psychopathic deviate scales and BDI than those without insomnia. CONCLUSIONS: Our results suggest that insomnia complaints are very common in OSAHS patients and the psychological problems are more frequently found in OSAHS patients with insomnia symptom than those without it.
