Difference in Nocturnal Erectile Function Between SRPE Patients and Normal People / 中山大学学报(医学科学版)

ObjectiveTo compare the nocturnal erectile function between SRPE patients and normal people. MethodsFrom July 1st， 2019 to December 15th， 2022， a clinical comparative study was conducted on 29 SRPE patients （experimental group） and 58 volunteers （control group） who visited our urology department. The Rigiscan System was used to monitor sleep monitoring time， the number of nocturnal erections and the rigidity， duration and circumference growth of the penis when the erection reached 60%～79% and 80%～100%， respectively. The patients and volunteers were asked to make written records when they woke up， and then the total number of awakenings and the number of awakenings when the penis erection reached 60% and 80% were compared between the two groups. ResultsAge was eliminated by matching. There was no statistically significant difference in sleep monitoring time， rigidity， circumference growth and duration of the penis when the erection reached 60%～79% and 80%～100%. between the two groups. In terms of sleep， there was a statistically significant difference in the total number of awakenings between the two groups［3（2 ~ 4）vs 0（0 ~ 0），P<0.01］ .And the same was true for the number of awakenings when the penis erection exceeded 60%～79% ［1（0 ~ 1）vs 0（0 ~ 0），P<0.01］and 80%～100% ［2（1 ~ 3）vs 0（0 ~ 0），P<0.01］. ConclusionRigiscan monitoring showed that there was no difference between SRPE patients and normal male in nocturnal penile erection function. Painful awakening usually occurs when the penis erection reaches 60%～79% or 80%～100%， which reveals that SRPE may be caused by abnormal sensation of nocturnal erections or pain sensitivity in some of these patients.

Clinical and electrophysiological study of sleep-related hypermotor epilepsy during rapid eye movement sleep / 中华神经科杂志

Objective:To explore the electro-clinical characteristics of sleep-related hypermotor epilepsy (SHE) in rapid eye movement (REM) stage.Methods:Five patients of SHE in REM stage were studied and followed up in the Electroencephalogram Monitoring Center, Department of Neurology, Xijing Hospital, the Air Force Military Medical University, from January 2016 to August 2021.Results:Among the 5 patients, there are 3 male patients, aged 21 to 46 years. A total of 23 seizures were monitored in 5 patients, of which 22 occurred in REM sleep and 1 occurred in non-REM Ⅲ sleep. Each attack lasted from 30 seconds to 1 minute, and was manifested as "hyperkinetic attack" during sleep, with or without disturbance of consciousness. There were no obvious abnormalities in electroencephalography during 13 attacks, with the focal sharp slow waves or slow waves during 9 attacks, and the focal slow waves occurrence at the end of the 10 attacks.Conclusion:Most of the hypermotor epileptic seizures in REM stage started from awakening reaction, and the interictal discharges occured in waking and non-REM sleep stage, which is necessary to distinguish from the REM sleep behavior disorder.

Cirugía del sueño: Definición de una especialidad emergente, propuesta de una clasificación anatomofuncional integral e indicaciones

Resumen Los trastornos respiratorios del sueño (ronquido primario y síndrome de apnea-hipopnea obstructiva del sueño) han sido tratados mediante múltiples modalidades a lo largo de la historia. Sin embargo, la cirugía de la vía aérea superior siempre ha estado presente, dando cabida a la aparición de múltiples técnicas para este fin. El estudio adecuado de los sitios anatómicos de estrechez o colapso de la vía aérea superior y sus contribuyentes (bajo el concepto de topodiagnóstico) y el mejor entendimiento de los mecanismos de acción de los diferentes procedimientos descritos, ha permitido el nacimiento de una nueva disciplina, dedicada al manejo quirúrgico planificado de este grupo de patologías: la cirugía del sueño.

Abstract Sleep-related breathing disorders (primary snoring and obstructive sleep apnea-hypopnea syndrome) have been treated with multiple modalities throughout history. However, upper airway surgery has always been present, giving appearance of multiple techniques for this purpose. The adequate study of the anatomical sites of upper airway narrowness or collapse and its contributors (under the concept of topodiagnosis) and a better understanding of the different procedures, has allowed the birth of a new discipline, dedicated to a planned surgical management for this group of pathologies: sleep surgery.

Problemas com o sono e fatores associados na população brasileira: Pesquisa Nacional de Saúde, 2013 / Sleep-related problems and associated factors among the Brazilian population: National Health Survey, 2013

Resumo O objetivo deste estudo foi estimar a frequência de problemas com o sono e os fatores associados, analisando dados da Pesquisa Nacional de Saúde, realizado em 2013 no Brasil. Os problemas com o sono foram avaliados com a pergunta "Nas duas últimas semanas, com que frequência o(a) sr(a) teve problemas no sono, como dificuldade para adormecer, acordar frequentemente à noite ou dormir mais do que de costume?", as respostas foram agrupadas em: nenhum dia, menos da metade dos dias e mais da metade dos dias. Dos indivíduos avaliados, 71,1% relataram não ter problemas com o sono em nenhum dia, 14,0% em pelo menos metade dos dias e 14,9% em mais da metade dos dias. As maiores frequências de problemas com o sono foram relatadas pelas mulheres e com o aumento da idade. Para homens e mulheres, tabagismo, consumo de bebidas alcoólicas, inatividade física, comportamento sedentário e hipertensão arterial apresentaram associação significativa com a frequência de problemas com o sono em mais da metade dos dias, e o excesso de peso para as mulheres. Assim, foi elevada a frequência de problemas com o sono na população brasileira. Mulheres, indivíduos mais velhos, com comportamentos de risco relacionados ao estilo de vida, hipertensão arterial e excesso de peso corporal foram os subgrupos em maior risco.

Abstract The scope of this study was to estimate the frequency of sleep-related problems and associated factors. It was a study based on data from the National Health Survey conducted in Brazil in 2013. Sleep-related problems were assessed with the question "How often have you had sleep problems in the last two weeks, such as difficulty falling asleep, waking up frequently during the night or sleeping more than usual?" The answers were grouped into: none of the days, less than half of the days and more than half of the days. Of the individuals evaluated, 71.1% reported having no problems with sleep on any day, 14.0% on at least half of the days and 14.9% on more than half of the days. The highest frequencies of sleep-related problems were reported by women and more advanced age. For men and women, smoking, alcohol abuse, physical inactivity, sedentary behavior, and high blood pressure were significantly associated with the frequency of sleep problems on more than half of the days, and also excess weight for women. Thus, the frequency of sleep-related problems in the Brazilian population was high. Women, older individuals with lifestyle-related risk behaviors, high blood pressure, and overweight were the highest risk subgroups.

The association of sleep-related breathing disorders among pediatric patients with allergic rhinitis: A cross-sectional study in a university hospital

@#<p style="text-align: justify;"><strong>Introduction:</strong> Allergic rhinitis is a common condition in children linked to sleep-related breathing disorders (SRBD). Because of nasal congestion, it can cause obstructive sleep apnea, sleep fragmentation, and excessive fatigue. Studies regarding its association with SRBD is limited.</p><p style="text-align: justify;"><strong>Objectives:</strong> To determine the association of allergic rhinitis with sleep-related breathing disorders.</p><p style="text-align: justify;"><strong>Methodology:</strong> A cross-sectional analytical study involving pediatric patients diagnosed with allergic rhinitis was conducted. Allergic rhinitis severity was evaluated with the ARIA classification. SRBD was identified using the validated Filipino version of the pediatric sleep questionnaire. Potential association between allergic rhinitis and SRBD were assessed using the student's t-test, Fisher's exact test and odds ratio.</p><p style="text-align: justify;"><strong>Results:</strong> A total of 66 children with mean age 8.2 years were included in the study.

Advances in sleep-related hypermotor epilepsy / 浙江大学学报·医学版

Sleep-related hypermotor epilepsy (SHE), formerly known as nocturnal frontal epilepsy, is characterized by asymmetrical tonic or complex hypermotor seizures during sleep, with transient, frequent and clustering attack. The accurate incidence is not known but somehow low, which is estimated about 1.8/100 000. The differential diagnosis between SHE and parasomnias may be challenging due to possible similarities between the two sleep-related manifestations. In a majority of patients, the etiology is unknown. Identified etiologies are heterogeneous and structural abnormalities,which are involved in the severity and prognosis of SHE. In terms of treatment, it mainly includes pharmacological therapy and surgery. Carbamazepine seems to be the drug of choice in SHE patients, and epilepsy surgery provides excellent results in selected drug-resistant SHE cases. This review will focus on diagnosis, pathogenesis, treatment and prognosis of SHE, aiming to promote its early diagnosis and appropriate treatment.

Trastornos Paroxísticos No Epilépticos En Pre-Escolares / Non-epileptic paroxysmal disorders in pre-school children

Los trastornos paroxísticos no epilépticos son comunes en la población de niños pre-escolares. Estas condiciones incluyen una variedad de eventos cuyas manifestaciones y fisiopatología son muy distintas. Por esa razón, el diagnóstico puede representar un difícil reto. En algunas ocasiones, estudios como el EEG o la polisomnografía pueden ayudar a clarificar el diagnóstico y descartar un trastorno epiléptico. Sin embargo, la historia clínica y el examen físico suelen ser suficientes para llegar al diagnóstico correcto. En este artículo, presentamos información sobre los trastornos paroxísticos no epilépticos más comunes en la población de niños pre-escolares, incluyendo: tics, discinesias, eventos relacionados al sueño, etc. Además, discutimos estrategias para el diagnóstico y opciones de tratamiento.

Paroxysmal events are commonly encountered in toddlers. These events include a variety of conditions with different manifestations and pathophysiology. For that reason, the diagnosis of these events can be challenging. In some instances, studies such as EEG and polysomnogram may be useful to differentiate between epileptic and non-epileptic events. In the majority of cases, a complete clinical history is enough to make an appropriate diagnosis. In this article, we review some of the most common paroxysmal non-epileptic events affecting toddlers, such as: tics, dyskinesias, sleep related events, etc. We also discuss diagnostic strategies and treatment options.

Considerations on priapism / 中华男科学杂志

Priapism is a rare pathological penile erection, and there are some inadequacies in its definition, classification, diagnosis, and therapeutic strategies. In this article, we sum up our years of experience with priapism and put forward some new views and ideas about its definition, classification, pathophysiologic process, pathological change, diagnostic essentials, therapeutic measures, indications of successful treatment, and post-therapeutic rehabilitation of erectile function. We also describe the clinical features, diagnosis and treatment of some special types of priapism, such as intermittent seizure, sleep-related painful erection, and tumor-related priapism, hoping to help urologists and andrologists in the further understanding and management of priapism.

Case of a 19-Year-Old Male with Nocturnal Groaning (Catathrenia) / 수면정신생리

Catathrenia is a rare sleep disease characterized by monotonous groaning sounds that appear to be related with prolonged expiration, commonly experienced during rapid eye movement (REM) sleep. Catathrenia is also known as nocturnal groaning or sleep-related groaning and is currently categorized as a sleep-related breathing disorder. We present a rare case of a 19-year-old male with nocturnal groaning during non-REM sleep. We suggest that if catathrenia is suspected, polysomnography should be utilized to differentiate it from various sleep disorders such as snoring, central sleep apnea, sleep talking, parasomnia, and sleep-related movement disorders.

Effects of Electrical Automatic Massage of Whole Body at Bedtime on Sleep and Fatigue

OBJECTIVES: To investigate the effect of electrical automatic massage (EAM) at bedtime on sleep quality and fatigue. METHODS: We recruited consecutively 35 adults (23 male, 48.7±8.07 y) who complained of poor sleep (Pittsburgh Sleep Quality Index≥5) and fatigue (Chalder Fatigue Scale≥4). This is a cross over study including two consecutive sleep studies with or without EAM. The EAM session includes preset ‘sleep mode’, which last 30 minutes covering whole body. Participants were seated in the commercially available massage chair (REX-L®) under the calm and dim light condition immediately before polysomnography. Participants reported perceived sleep latency, sleep duration, and fatigue using visual analogue scale following morning. RESULTS: Polysomnography parameters and subjective reports were compared between sleep with EAM and sleep without EAM. Paired comparison on average revealed sleep structure improvement N1 (13.6→10.9%) and N2 sleep (59.3→57.2%) decreased, and N3 sleep increased (3.0→6.4%), as well as sleep latency (10.3→5.6 min). Improvement in arousal index (17.1→13.0/h) and apnea-hypopnea index (9.1→7.0/h) were also seen following sleep after EAM. Sleep efficiency and total sleep time were not changed by EAM. Participants subjective reports also indicated better sleep on EAM; more lengthened sleep (306→330 minutes) and more relieved fatigue significantly after EAM. CONCLUSIONS: This study demonstrated that muscle relaxation through EAM at bedtime may improve the sleep and alleviate fatigue. It suggests that EAM may be one of alternatives to promote sleep quality. Further studies in a clinical setting are warranted to support this finding.

Relationship between Prader-Willi syndrome and sleep related breathing disorders / 国际儿科学杂志

Prader-Willi syndrome( PWS) is a type of genetic disease,which is associated with low mus-cle tone,growth and development,progressive fatal obesity and sleep related respiratory disorders(SRBD). Ob-structive sleep apnea hypopnea syndrome( OSAHS) is the most common type of SRBD. The cause,influencing factors and treatment of OSAHS in patients with PWS are described in this paper. To understand the degree of OSAHS in children with PWS,the polysomnography is recommended.

Zolpidem Induced Sleep-related Eating and Complex Behaviors in a Patient with Obstructive Sleep Apnea and Restless Legs Syndrome

Zolpidem-induced sleep-related complex behaviors (SRCB) with anterograde amnesia have been reported. We describe herein a case in which the development of zolpidem-induced sleep-related eating disorder (SRED) and SRCB was strongly suspected. A 71-year-old Korean male was admitted to the Department of Psychiatry due to his repetitive SRED and SRCB with anterograde amnesia, which he reported as having occurred since taking zolpidem. The patient also had restless legs syndrome (RLS) and obstructive sleep apnea (OSA). His baseline serum iron level was low at admission. Zolpidem discontinuation resulted in the immediate disappearance of his SRED, but did not affect his RLS symptoms. These symptoms rapidly improved after adding a single i.v. iron injection once daily, and so he was discharged to day-clinic treatment. These findings indicate that zolpidem can induce SRCB. Although the pathophysiology of zolpidem-induced SRED and other SRCB remains unclear, clinicians should carefully monitor for the potential induction of complex behaviors associated with zolpidem in patients with comorbid RLS or OSA.

Two Cases of Sleep-Related Painful Erection

Sleep-related painful erection (SRPE) is characterized by deep penile pain accompanied with erection occurring rapid eye movement (REM) movement period. Two (47-year-old and 40-year-old, respectively) male visited with the complaint of painful penile erection occurring during sleep. They had no problems with erection during daytime sexual activities except for mild premature ejaculation in one patient. Urologic inspections revealed no focal abnormalities. Polysomnography with simultaneous penile erection monitoring showed several episodes of awakening with painful erection which are time-locked to onset of REM sleep periods. According to the diagnostic criteria in international classification of sleep disorders, each patient was diagnosed to have chronic, severe SRPE. Despite of a low prevalence of SRPE, this condition should be considered in a patient who presents with nocturnal penile. A polysomnography accompanied with penile erection recording may help confirm diagnosis.

Síndrome de hipoventilación alveolar central congénita / Congenital central alveolar hypoventilation syndrome

ResumenIntroducción: El síndrome de hipoventilación alveolar central congénita (SHACC) es un raro trastorno respiratorio del dormir, aunque cada vez más frecuentemente diagnosticado en clínicas de sueño y servicios de neumología pediátrica. Si bien se desconoce su epidemiología, en la literatura médica existen cerca de 300 casos reportados, y su incidencia es de 1 caso por cada 200,000 recién nacidos vivos. Se caracteriza por hipoventilación alveolar que se presenta o empeora durante el sueño. Es secundario a la disminución/ausencia de la respuesta ventilatoria a la hipercapnia o hipoxemia, y en el 90% de los casos es debido a una mutación tipo PARM del gen PHOX2B. Su tratamiento incluye ventilación mecánica y marcapasos diafragmático. Si la terapéutica no se inicia en forma temprana, el paciente desarrollará insuficiencia respiratoria crónica, hipertensión arterial pulmonar, cor pulmonale y la muerte.Casos clínicos: Se presentan tres casos de SHACC diagnosticados, tratados y en seguimiento en la Clínica de Trastornos Respiratorios del Dormir del Instituto Nacional de Enfermedades Respiratorias.Conclusiones: El diagnóstico temprano es importante para el inicio del soporte ventilatorio, y para prevenir el desarrollo de complicaciones y reducir la mortalidad.

AbstractBackground: Congenital central alveolar hypoventilation syndrome (CCAHS) is a rare sleep-related breathing disorder. Although increasingly frequently diagnosed in sleep clinics and pediatric pulmonology services, its epidemiology is not known. There are about 300 reported cases reported in the literature with an incidence of 1 case per 200,000 live births. CCAHS is characterized by alveolar hypoventilation that occurs or worsens during sleep and is secondary to a reduction/absence of the ventilatory response to hypercapnia and/or hypoxemia. In 90% of the cases it is due to a PARM-type mutation of the PHOX2B gene. Treatment includes mechanical ventilation and diaphragmatic pacemaker. If therapy is not initiated promptly the patient can evolve to chronic respiratory failure, pulmonary hypertension, cor pulmonale and death.Case reports: In this paper we present three cases of CCAHS diagnosed, treated and followed up at the Sleep Disorders Clinic of the National Institute of Respiratory Diseases in Mexico.Conclusions: Early diagnosis is important to initiate ventilatory support so as to prevent any complications and to reduce mortality.

Menopause and Sleep Related Breathing Disorders / 대한폐경학회지

Women after the menopause appear to be more susceptible to sleep related breathing disorders (SBDs). The increased prevalence of SBDs in postmenopausal women may be related to weight gain and the decline in female sex hormones levels. These conditions may cause upper airway obstruction, which can result in sleep disruption. Other sleep disorders, such as insomnia, depression, and fibromyalgia must be ruled out with SBDs in postmenopausal women with sleep difficulties. Once SBD is strongly suspected through medical history and precise physical examinations, polysomnogram is required for confirmatory diagnosis. In addition, other examinations besides polysomnogram should be performed to detect obstructed regions. Treatment of SBD can be classified into surgical method and non-surgical method. Treatment options must be carefully selected by considering the patient's clinical examinations, patient's preference, age and life style.

The Correlation between Severity of Sleep Apnea, Sleep and Mood Related Scales, and Activity During Sleep in Obstructive Sleep Apnea Syndrome Patients / 수면정신생리

OBJECTIVES: This study aims to analyze the association between the severity of sleep apnea, sleep and mood related scales, and activity during sleep in obstructive sleep apnea syndrome (OSAS) patients. METHODS: One hundred seventy six drug-free male patients confirmed as OSAS (average age=43+/-11 years) were selected through nocturnal polysomnography (NPSG). OSAS was diagnosed with apnea-hypopnea index (AHI) >5, mean AHI was 39.6+/-26.0. Sleep related scales were Stanford Sleepiness Scale (SSS), Epworth Sleepiness Scale (ESS), Pittsburg Sleep Quality Index (PSQI) and Morningness-Eveningness Scale (MES). Mood related scales were Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), State-Trait Anxiety Inventory (STAI) I, II and Profile of Mood States (POMS). NPSG was performed overnight with both wrist actigraphy (WATG). Parameters produced from WATG were total activity score, mean activity score and fragmentation index. We analyzed the correlation between each scale, AHI scored from NPSG and activity score analyzed from WATG. RESULTS: ESS showed significant positive correlation with PSQI, BDI, BAI and STAI I, II, respectively (p<0.01). SSS showed significant positive correlation with PSQI and BAI (p<0.05, p<0.01). BAI showed significant positive correlation with total activity score, mean activity score and fragmentation index (p<0.05, p<0.01, p<0.05). Total activity score showed significant positive correlation with ESS and BAI, respectively (p<0.05). Fragmentation index showed significant positive correlation with ESS, PSQI and BAI (p<0.05, p<0.01, p<0.05). AHI, indicator of sleep apnea is showed no significant correlation with each sleep and mood related scale. CONCLUSION: The degree of daytime sleepiness tends to be associated with night sleep satisfaction, depression and anxiety, and the activity during sleep rather than the severity of sleep apnea.

Sleep-Related Eating Disorder / 수면정신생리

Sleep-related eating disorder (SRED) is a newly recognized parasomnia that describes a clinical condition of compulsive eating under an altered level of consciousness during sleep. Recently, it is increasingly recognized in clinical practice. The exact etiology of SRED is unclear, but it is assumed that SRED might share features of both sleepwalking and eating disorder. There have been also accumulating reports of SRED related to the administration of various psychotropic drugs, such as zolpidem, triazolam, olanzapine, and combinations of psychotropics. Especially, zolpidem in patients with underlying sleep disorders that cause frequent arousals, may cause or augment sleep related eating behavior. A thorough sleep history is essential to recognition and diagnosis of SRED. The timing, frequency, and description of food ingested during eating episodes should be elicited, and a history of concurrent psychiatric, medical, sleep disorders must also be sought and evaluated. Interestingly, dopaminergic agents as monotherapy were effective in some trials. Success with combinations of dopaminergic and opioid drugs, with the addition of sedatives, has also been reported in some case reports.
