RESUMO
Objectives@#Our study aims to investigate the clinical and polysomnographic variables associated with subjective sleep perception. @*Methods@#Among the patients who underwent nocturnal polysomnography (PSG) at the Center for Sleep and Chronobiology of Seoul National University Hospital from May 2018 to July 2019, 109 diagnosed with insomnia disorder based on DSM-5 were recruited for the study, and their medical records were retrospectively analyzed. Self-report questionnaires about clinical characteristics including Pittsburgh sleep quality index (PSQI), Beck depression inventory (BDI), and Epworth sleepiness scale (ESS) were completed. Subjective sleep quality was measured using variables of subjective total sleep time (subjective TST), subjective sleep onset latency (subjective SOL), subjective number of awakenings, morning feeling after awakening, and sleep discrepancy (subjective TST–objective TST) the morning after PSG. Pearson and Spearman correlation analyses were used to determine the factors associated with subjective sleep perception. @*Results@#In patients with insomnia, subjective TST was negatively correlated with Wake After Sleep Onset (WASO) (p = 0.001) and N1 sleep (p = 0.039) parameters on polysomnography. Also, it was negatively correlated with PSQI (p < 0.001) and BDI (p = 0.014) scores. Sleep discrepancy was negatively correlated with PSQI score (p = 0.018). Morning feeling was negatively correlated with PSQI (p = 0.019) and BDI (p < 0.001) scores. @*Conclusion@#Our results demonstrated that subjective sleep perception is associated with PSG variables (WASO and N1 sleep) and with PSQI and BDI scores. In clinical practice, it is helpful to assess and manage insomnia patients in consideration of objective sleep variables, subjective sleep quality, and depressed mood, which can influence subjective sleep perception.
RESUMO
OBJECTIVES: Obstructive sleep apnea (OSA) is a sleep-related breathing disorder that is characterized by repetitive collapse or partial collapse of the upper airway during sleep in spite of ongoing effort to breathe. It is believed that OSA is usually worsened in REM sleep, because muscle tone is suppressed during REM sleep. However, many cases showed a higher apnea-hypopnea index (AHI) during NREM sleep than during REM sleep. We aimed here to determine the characteristics of REM sleep-dependent OSA (REM-OSA) and NREM sleep-dependent OSA (NREM-OSA). METHODS: Five hundred sixty polysomnographically confirmed adult OSA subjects were studied retrospectively. All patients were classified into 3 groups based on the ratio between REM-AHI and NREM-AHI. REM-OSA was defined as REM-AHI/NREM-AHI > 2, NREM-OSA as NREM-AHI/REM-AHI > 2, and the rest as sleep stage-independent OSA (IND-OSA). In addition to polysomnography, questionnaires related to subjective sleep quality, daytime sleepiness, and emotion were completed. Chi-square test, ANOVA, and ANCOVA were performed. RESULTS: There was no age difference among subgroups. The REM-OSA group was comprised of large proportions of mild OSA and female OSA patients. These patients experienced poor sleep and more negative emotions than other two groups. The AHI and oxygen desaturation index (ODI) were lowest in REM-OSA. Sleep efficiency and N3 percentage of REM-OSA were higher than in NREM-OSA. The percentage of patients who slept in a supine position was higher in REM-OSA than other subgroups. IND-OSA showed higher BMI and larger neck circumference and abdominal circumference than REM-OSA. The patients with IND-OSA experienced more sleepiness than the other groups. AHI and ODI were highest in IND-OSA. NREM-OSA presented the shortest total sleep time and the lowest sleep efficiency. NREM-OSA showed shorter sleep latency and REM latency and higher percentage of N1 than those of REM-OSA and the highest proportion of those who slept in a lateral position than other subgroups. NREM-OSA revealed the highest composite score on the Horne and Östberg questionnaire. With increased AHI severity, the numbers of apnea and hypopnea events during REM sleep decreased, and the numbers of apnea and hypopnea events during NREM sleep increased. The results of ANCOVA after controlling age, sex, BMI, NC, AC, and AHI showed the lowest sleep efficiency, the highest AHI in the supine position, and the highest percentage of waking after sleep onset in NREM-OSA. CONCLUSION: REM-OSA was associated with the mild form of OSA, female sex, and negative emotions. IND-OSA was associated with the severe form of OSA. NREM-OSA was most closely related to position and showed the lowest sleep efficiency. Sleep stage-dependent characteristics could provide better understanding of OSA.

OBJECTIVES: To understand the risk factors of demographic data in geriatric depression scale, and suicidality among in elderly who live alone at one urban region. METHODS: In 2009, 589 elderly who live alone(age> or =65) were carried out a survey about several socio-demographic data, Korean version of the Geriatric Depression Scale(SGDS-K) and Suicidal Ideation Questionnaire (SIQ). Statistical analysis was performed for the collected data. RESULTS: Mean age of elderly who live alone is 75.69(SD 6.17). 40.1% of participants uneducated, 31.4% graduate from elementary school, 12.9% graduate from high school, 11.7% graduate from middle school, 3.2% graduate from university. Religionless, having past history of depression or physical diseases, low subjective satisfaction of family situation, and not having any social group activity have significance to depressive symptoms of elderly who live alone. Having past history of depression, religionless, low subjective satisfaction of family situation have significance to suicidality. Especially, low subjective satisfaction of family situation and having past history of depression are powerful demographic factor both depressive symptoms and suicidality of elderly who live alone. CONCLUSIONS: When we take care elderly who live alone, we should consider many things, but especially the social support network such as family satisfaction and past history of depression for reducing or preventing their depression and suicide both elderly depression and suicide who live alone.

According to current evidence, human immunodeficiency virus (HIV)-infected patients who have undergone treatment with antiretroviral therapy are at greater risk of developing herpes zoster, not when they are severely immunocompromised, but, paradoxically, when their immune system is recovering. This is a manifestation of the immune reconstitution inflammatory syndrome (IRIS). Here we report on a case of IRIS, presented as herpes zoster in a HIV-infected patient after undergoing highly active antiretroviral therapy (HAART).

BACKGROUND AND OBJECTIVES: Laser-assisted uvulopalatoplasty is well established and relatively successful operation in the treatment of snoring and obstructive sleep apnea (OSA). But, there have been no reports about snoring sound of patients who had been performed LAUP. This study was performed to evaluate the results of LAUP analysing preoperative snoring sounds. MATERIALS AND METHODS: There were 38 patients who were diagnosed as OSA by polysomnography and had been performed LAUP between Mar, 1998 and July, 2002. Preoperative and postoperative snoring sounds were recorded during sleep and we performed an acoustic analysis using spectrogram (SPG), which was classified. And postoperative subjective satisfaction of bed time partner was compared in each type and the degree of satisfaction was measured by VAS (visual analogue scale) score. According to previous study, types of spectrogram of snoring sounds were classified as palatal, tongue base and mixed. RESULTS: In postoperative analysis, snoring loudness was most decreased in palatal type, and snoring pitch was only increased in tongue base type. The average satisfaction of bed time partner was highest at palatal type and lowest at tongue base type. CONCLUSION: Preoperative analysis of snoring sounds can aid the prediction of the loudness and pitch of snoring sounds and the subjective satisfaction of patients after LAUP.

BACKGROUND AND OBJECTIVES: OSAS is thought to be due to an excessive loss of muscle tone in the upper airway or an abnormal reflex regulation of upper airway function during sleep. The aim of this study was to investigate the distribution of myosin heavy chain (MHC) isoforms of musculus uvulae in OSAS and snorers. Materials and Methods: Thirty seven patients included in the study underwent an uvulo-palato-pharyngoplasty (UPPP). All subjects had polysomnographic study before UPPP. ATPase stain at pH 9.4 were applied to muscle specimens obtained during UPPP. The numbers of MHC type I and II isoforms were counted. The patients were divided into three groups according to their repiratory disturbance index (RDI):mild (0-20), moderate (21-40), severe (>40). The differences in the distribution of muscle fiber types were compared between these groups. The correlation between the distribution of the fibers and the body mass index / age / RDI / minimum O2 saturation / duration of sleep apnea was investigated. RESULTS: The mean percentages standard deviation of type I fibers according to the severity of sleep apnea were as follows:22.5+/-3.2% in mild sleep apnea group (n=5), 19.8+/-2.3% in moderate sleep apnea group (n=1), 17.5+/-3.6% in severe sleep apnea group (n=1). There were statistically significant differences in the distribution of MHC type I and II isoforms between mild group and moderate and / or severe group (p.05). CONCLUSION: The proportion of MHC type I isoforms in musculus uvulae was decreased according to the severity and duration of sleep apnea (p<.01).

BACKGROUND AND OBJECTIVES: Infections account for much of the morbidity and nearly half of the mortality in renal transplant recipient. Recently there has been a marked increase in the number of renal transplantation and preoperative screening test for chronic paranasal sinusitis. Authors analyzed the clinical manifestations and postoperative courses after the endoscopic sinus surgery in the patients with end stage renal disease. MATERIALS AND METHODS: 1,175 patients had been consulted to the otolaryngology department for routine evaluations about the presence of acute and chronic paranasal sinusitis prior to kidney transplantation between Jun. 1989 to Aug. 1998. Among them, 30 patients were diagnosed as significant chronic paranasal sinusitis and 5 patients were treated with endoscopic sinus surgery. Medical records and radiographs of the 30 patients were reviewed retrospectively. RESULTS: The prevalence of chronic paranasal sinusitis in patients with end stage renal disease was 2.5%. Twelve patients were asymptomatic and chief complaints of symptomatic patients were nasal obstruction (55.6%), rhinorrhea (27.8%), and postnasal drip (16.7%). Eleven patients had nasal polyps and twelve patients showed purulent discharge. All the patients who were surgically treated experienced postopertive bleeding and 2 of them required transfusion. CONCLUSION: The presence of asymptomatic sinusitis among the patients with end stage renal disease necessitates diagnositc screening tests for chronic paranasal sinusitis. The incidence of postoperative bleeding after endoscopic sinus surgery in patients with end stage renal disease is much higher than that of otherwise healthy sinusitis patients.

BACKGROUND AND OBJECTIVES: Overcorrection is defined as obvious deviation of the septum to the opposite direction after septoplasty and it is not infrequently developed in young patients. We investigated the rate of its incidence, especially in relation to age. MATERIALS AND METHODS: We retrospectively studied 1,124 patients undergoing septoplasty operation for septal deviation between 1994 and 1999. The operations and postoperative observation were performed by a single surgeon. We reviewed the medical records for age, sex, symptoms, combined operations, direction of deviation before and after septoplasty. RESULTS: Out of 1,124 patients, 22 (2.0%) had their septum overcorrected after septoplasty and 21 (95%) complained of nasal obstruction of the newly deviated side. The incidence of overcorrection was 7.3% (16/218) in teens, 1.7% (5/294) in twenties, 0.4% (1/250) in thirties, and 0% in older ages. The incidence in teens and early twenties was 5%. Patients of teenagers revealed significantly higher incidence as compared to other age groups (p<0.05). CONCLUSION: Overcorrected septum as a complication of septoplasty develops at the incidence rate of 5% in patients of teens and early twenties. Authors suggest that the depth of cross-hatching incision on the cartilage should be superficial or half-thickness to avoid overcorrection in young patients. And the possibility of overcorrection or revision septoplasty should be informed preoperatively.

Paragangliomas are neoplasms that arise from extra-adrenal paraganglia, microscopic islands of cells derived from the neural crest. In the head and neck region, paraganglionic tissue is distributed in the superior and inferior paraganglia, the carotid body, the vagal body, and the jugulotympanic region. Approximately 10% of patients with a paraganglioma have a family history of such tumors. Multiple lesions can be found in 26% of patients with family history. Patients with multiple paragangliomas have a higher risk of having functional pheochromocytoma and should undergo a pretreatment screening for vasopressor substances. Similarly, patients with a family history should undergo four-vessel arteriography to rule out any multiple and clinically unrecognized lesions. The authors have experienced three cases of multiple paragangliomas, which were managed surgically. Two cases were bilateral carotid body tumors and two cases were accompanied by glomus jugulare. Of these, one case had family history. We report three cases of multiple paragangliomas with a review of literatures.
