Resolution of Sleep Disturbance and Improved Functional Outcomes After Rotator Cuff Repair.

BACKGROUND: Most patients experience sleep disturbances before rotator cuff repair, with these symptoms largely improving postoperatively. However, the relationship between the resolution or persistence of sleep disturbance and patient-reported outcomes after rotator cuff repair remains unknown. PURPOSE: To compare outcomes after rotator cuff repair between patients who reported a preoperative sleep disturbance and those who did not. Outcomes at various time points after surgery were also assessed in relation to the persistence or resolution of sleep disturbance. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Patients undergoing primary arthroscopic rotator cuff repair at a tertiary academic center were prospectively enrolled in a registry database. Patient characteristics were obtained preoperatively and validated patient-reported outcome measures (PROMs) were obtained pre- and postoperatively, including the visual analog scale for pain, American Shoulder and Elbow Surgeons score, Single Assessment Numeric Evaluation, Simple Shoulder Test, and Veterans RAND 12-Item Health Survey Physical and Mental components. Sleep disturbance was evaluated via responses to Simple Shoulder Test question 2. Patients with and without sleep disturbance were compared before and after surgery. RESULTS: In total, 293 patients were prospectively enrolled. A total of 262 (89.8%) patients reported a sleep disturbance preoperatively. Of these, 221 (84.4%) reported a resolution of sleep disturbance by 2 years postoperatively. After adjustment for age, workers' compensation status, and Cofield tear size, patients with a preoperative sleep disturbance reported significantly worse baseline PROMs, apart from the Veterans RAND 12-Item Health Survey Mental component, before surgery. However, postoperatively, these patients had greater improvement in PROMs, and no significant remaining differences were seen at follow-up between patients with and without preoperative sleep disturbance. Among patients who reported a preoperative sleep disturbance, those whose symptoms resolved postoperatively had superior PROM scores as well as significantly greater improvements from preoperative baseline values compared with patients with persistent sleep disturbances after surgery. CONCLUSION: Patients with preoperative sleep disturbances reported worse baseline functional scores before rotator cuff repair compared with patients without sleep disturbance. These disturbances largely resolved after surgery, with postoperative outcomes comparable with those of patients who reported no preoperative sleep concerns. Patients whose sleep disturbances resolved postoperatively also reported superior PROM scores compared with patients whose sleep disturbances persisted postoperatively.

Sleep Disturbances and Disorders in Patients with Knee Osteoarthritis and Total Knee Arthroplasty.

➤: There is increasing evidence that patient-reported outcomes following total knee arthroplasty (TKA) are associated with psychosocial factors and pain catastrophizing. Sleep disturbance, pain, and mental health have a complex interaction, which, if unrecognized, can be associated with impaired patient-reported outcomes and dissatisfaction following TKA. ➤: The gold standard of objective sleep assessment is polysomnography, which is not feasible to use routinely for TKA patients. Wearable devices are a validated and less costly alternative. ➤: Subjective sleep measures, such as the Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, or Patient-Reported Outcomes Measurement Information System (PROMIS) computerized adaptive test sleep domains, are simple to administer and provide additional insight into sleep disturbance. Although objective and subjective measures do not correlate precisely, they can be informative together. ➤: Sleep disturbances in the elderly population are common and multifactorial in etiology, stemming from the interplay of sleep disorders, medication side effects, and pain. Commonly prescribed medications following TKA as well as postoperative pain can exacerbate underlying sleep disturbances. ➤: Obstructive sleep apnea (OSA) is prevalent in patients seeking TKA. In the setting of OSA, postoperative opioids can cause respiratory depression, resulting in consequences as severe as death. A standardized multimodal pain protocol including anti-inflammatories and gamma-aminobutyric acid (GABA) analogues may allow for decreased reliance on opioids for pain control. ➤: Surgeons should reassure patients that postoperative sleep disturbance is common and transient, collaborate with the patient's primary care doctor to address sleep disturbance, and avoid prescription of pharmaceutical sleep aids.

Changes in Pre- and Postsurgery for Drug Resistant Epilepsy: Cognition and Sleep.

BACKGROUND: Most patients with drug-resistant epilepsy (DRE) have cognitive impairment and sleep disturbance. There was a significant correlation between sleep disorders and cognitive dysfunction. This study performed surgical treatment on patients with DRE and observed seizures, sleep, and cognition in patients with DRE in 6th month after operation to clarify the correlation between sleep and cognition in DRE patients. METHODS: 21 individuals with DRE were recruited to enroll in this trial. Each participant completed epileptic focus resection. Seizure frequency was the principle index; the mean seizure frequency was 1 month before surgery and six months after surgery. Cognitive function was assessed by MMSE, and sleep status was assessed by PSQI and ActiGraph; assessments were performed before and 6 months after surgery. RESULTS: There were significant differences between conditions on all outcome measures; after 6 months of surgery, compared with before treatment, the monthly average seizure frequency of DRE decreased, which was statistically significant (P < 0.001) compared with that before treatment. The MMSE score of DRE patients was significantly higher than before (P < 0.01), especially the ability of attention, calculation, and recall in MMSE score, which was significantly higher than before operation (respectively, P < 0.001 and P < 0.01). The subjective sleep evaluation index PSQI and objective measurement of sleep latency, total sleep time, and sleep efficiency of patients with DRE by ActiGraph were statistically significant (respectively, P < 0.01) compared with that before treatment. There was a correlation between seizure frequency and MMSE (r = -0.8887, P < 0.0001), PSQI (0.5515, P < 0.01), sleep latency (0.5353, P < 0.05), total sleep time (-0.7814, P < 0.0001), and sleep efficiency (-0.4380, P < 0.05). CONCLUSIONS: Surgery can effectively reduce the epileptic seizures frequency in patients with DRE and indirectly improve the computational power, attention, recall ability, and sleep status of patients. However, this result did not show a correlation between improved cognitive function and sleep, so the patient's cognitive function may be caused by surgery to improve the frequency of seizures. So, whether the improvement of patients' sleep conditions can also significantly improve the frequency of attacks and cognitive function in patients with DRE needs further exploration.

Shoulder Surgery as an Effective Treatment for Shoulder-Related Sleep Disturbance: A Systematic Review.

PURPOSE: The purpose of this systematic review is to evaluate the current literature in an effort to investigate sleep quality and disturbances and the association with clinical outcomes of patients undergoing shoulder surgery. METHODS: A systematic review of the PubMed, Embase, and Cochrane Library databases was performed according to PRISMA guidelines. All English-language literature reporting clinical outcomes and sleep quality and disturbance after shoulder surgery was reviewed by 2 independent reviewers. Outcomes assessed included patient-reported outcomes (PROs) and sleep quality. Specific PROs included the Pittsburgh Sleep Quality Index (PSQI), Visual Analog Scale (VAS) for pain, Simple Shoulder Test (SST), University of California Los Angeles (UCLA) Shoulder Rating Scale, and American Shoulder and Elbow Surgeons Score (ASES). Study methodology was assessed using the Modified Coleman Methodology Score. Descriptive statistics are presented. RESULTS: Sixteen studies (11 level IV, 2 level III, 3 level II) with a total of 2748 shoulders were included (age, 12-91 years; follow-up, 0.25-132 months). In total, 2198 shoulders underwent arthroscopic rotator cuff repair (RCR), 131 shoulders underwent arthroscopic capsular release, 372 shoulders underwent total shoulder arthroplasty (TSA), 18 shoulders underwent comprehensive arthroscopic management, and 29 shoulders underwent sternoclavicular joint procedures. All shoulder surgeries improved self-reported sleep and PROs from before to after surgery. In RCR patients, PSQI scores were significantly associated with VAS scores, SST scores (r = 0.453, r = -0.490, P < .05, respectively), but not significantly associated with UCLA Shoulder rating scale or the ASES scores (r = 0.04, r = 0.001, P > .05, respectively). In TSA patients, PSQI scores were significantly associated with ASES scores (r = -0.08, P < .05). All 4 RCR studies and 1 TSA study using PSQI found significant improvements in mean PSQI scores within 6 to 24 months (P < .05). CONCLUSIONS: Surgical intervention for rotator cuff tear and glenohumeral osteoarthritis significantly improves self-reported sleep in patients with shoulder pain. However, there remains a dearth of available studies assessing the effects of surgical intervention for adhesive capsulitis, sternoclavicular joint instability, and sternoclavicular osteoarthritis on sleep. Future studies should use sleep-specific PROs and quantitative measures of sleep to further elucidate the relationship between sleep and the effect of shoulder surgery. LEVEL OF EVIDENCE: Level IV, systematic review of Level II-IV studies.

A Novel Presentation of the Acute Airway: Anti-IgLON5 Disease.

Anti-IgLON5 disease is a newly discovered novel sleep disorder at the crossroads of neurology and immunology. In addition to the underlying sleep disorder, anti-IgLON5 manifests with progressive aerodigestive symptoms such as dysphagia, stridor, and vocal cord paresis in 90% cases and may present to the otolaryngologist. Herein we present a case of a patient with anti-IgLON5 disease who presented to the hospital with an acute airway including marked stridor and respiratory failure requiring intubation and subsequently a tracheostomy.

Surgical management of pediatric patients with encephalopathy due to electrical status epilepticus during sleep (ESES).

ESES is a developmental epileptic disorder directly responsible for progressive encephalopathy and neurocognitive regression. The natural history, indications for surgical intervention, and predictors for favorable seizure and neuropsychological outcome remain unclear. We performed a retrospective review of children who underwent resective or disconnective surgery for ESES between January 2009 and July 2016 at a large tertiary pediatric center. Information on the patients' demographics, seizure semiology, radiographic and electrographic findings, and surgical management was collected. The primary outcome was seizure freedom at last follow-up visit, and secondary outcomes were neuropsychological improvement and electrographic ESES resolution. We identified 11 children who underwent surgery for ESES. The mean ages were 3.2 years for seizure onset, 7.1 years for formal ESES diagnosis, and 9.4 years for surgery. Seizure etiologies included cortical malformations (four patients), encephalomalacia and gliosis from prior hemorrhage or tumor resections (three patients), developmental porencephaly (one patient), and Rasmussen's encephalitis (one patient); the etiology was unknown in two children. Preoperatively, nine children had motor deficits, seven had speech and language delay, and three had visual field defects. All children had seizures and neuropsychological regression prior to surgical consideration. Focal cortical resections were performed in seven children, and hemispherectomies in four. Post-operatively, nine children experienced decreased seizure frequency, eight had neuropsychological improvement, and nine had resolution of electrographic ESES. Patients with poor surgical outcomes had more significant pre-operative comorbidities, in addition to bilateral ESES activity. In this case series, surgery for a carefully selected group of children with ESES is safe and feasible, yielding rates of seizure freedom and neuropsychological improvement that compare favorably with previous reports for antiepileptic drugs, benzodiazepines, and steroids. As we gain greater understanding into the management of ESES, surgery is an increasingly useful tool for patients with mild or moderate neurodevelopmental delay, focal epileptogenic foci, and hemi-ESES electrographic findings.

Sleep improvement after hip arthroplasty: a study on short-stem prosthesis.

PURPOSE: The purpose of this study was to evaluate sleep disturbance prospectively before and after short-stem hip arthroplasty. METHODS: A prospective study on 25 patients undergoing a primary unilateral total short-stem hip replacement was conducted. Patients were observed for six months. To evaluate the sleep quality and daytime sleepiness, the Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale were used. To assess the general physical health status, we used the Short Form 36 Health Survey (SF-36). Pain was recorded on a visual analog scale. RESULTS: The physical health status of the patients improved significantly (p < 0.05) during the six month follow-up period in seven out of nine categories. During the first post-operative week, the sleep quality stayed on an equal level to the pre-operative state, following a steady improvement over the next months (6 months p = 0.00). The daytime sleepiness showed a significant improvement during all the follow-ups (6 months p = 0.00). Pain decreased significantly from baseline to six months post-operatively (p = 0.00). There was no correlation between pain and sleep quality or pain and daytime sleepiness. CONCLUSION: According to our results, patients undergoing short-stem total hip arthroplasty can expect a 50% improvement of sleep quality and physical function six months after surgery.

Guidelines on the surgical management of sleep disorders: A systematic review.

OBJECTIVE: To facilitate the development of U.K. guidelines for sleep surgery and to guide sleep surgeons to existing guidelines relevant to their practice, we provide a systematic review and quality assessment of all existing guidelines on the surgical management of sleep disorders. METHODS: Systematic review using preferred reporting items for systematic reviews and meta-analyses (PRISMA) recommendations. Medline and Embase databases were searched from inception to April 2018. Publications were included if they described a guideline for the surgical management of sleep disorders. Three assessors used the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument to evaluate included guidelines. RESULTS: The systematic search revealed 1,161 publications. Twenty-two guidelines from eight countries were included. Fourteen focused on adults, five on children, and three on both. The guidelines discussed nasal, tonsillar, palatal, tongue, hyoid, maxillomandibular, tracheal, bariatric, and multilevel surgeries. The mean overall AGREE II quality score of included guidelines was 3.5 (range = 2 to 5.3; maximum possible score = 7). CONCLUSION: This article provides a summary and quality assessment of all published guidelines on the surgical management of sleep disorders. No U.K. guidelines were identified, and existing guidelines have several shortcomings. This highlights the need for robust U.K. national guidelines on sleep surgery to promote clinical and cost-effective care in this field. Our findings can be used by stakeholders as a foundation for the development of new guidelines and can be used by sleep surgeons to direct them to existing guidelines relevant to their practice, promoting evidence-based clinical care.

Long-term effects of bilateral subthalamic nucleus stimulation on sleep in patients with Parkinson's disease.

OBJECTIVES: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has been reported to have a positive effect on sleep-wake disturbance in Parkinson's disease (PD). We aimed to investigate the long-term effects of STN DBS on sleep in patients with PD. METHODS: Sixty-one patients with PD who had undergone bilateral STN DBS were followed for 3 years with assessments including the Parkinson's disease sleep scale (PDSS), Epworth sleepiness scale (ESS), total sleep hours per day, Unified PD Rating Scale part I-III, Hoehn & Yahr stage, levodopa equivalent dose, quality of life measure, and depression scale measured preoperatively and at 6 months after postoperatively, and annually thereafter. RESULTS: Among the 61 patients at baseline, 46 patients completed the last follow-up assessment. The total PDSS score significantly improved after STN DBS from baseline up to 3 years after STN DBS (79.0±30, 100.0±23.3, 98.8±23.0, 97.1±29.6, and 93.3±28.0 at baseline, 6, 12, 24, and 36 months, respectively, p = 0.006 for the change over time). Among the eight PDSS domains, the domains for overall quality of a night's sleep, sleep onset and maintenance insomnia, and nocturnal motor symptoms showed significant improvement after STN DBS (p = 0.036, 0.029, and < 0.001, respectively, for the change over time). The total sleep hours per day were increased, but the total ESS score did not show significant change after STN DBS (p = 0.001 and 0.055, respectively, for the change over time). Changes in the total PDSS were associated with changes in the depression and motivation items in the Unified PD Rating Scale part I, depression scale, and quality of life measure, but those variables at baseline were not predictive of changes in the total PDSS after STN DBS. CONCLUSION: In the largest systematic long-term follow-up study, the improvement in subjective sleep quality after bilateral STN DBS was sustained in PD patients. Improved nocturnal sleep and nocturnal motor symptoms were correlated with an improved mood and quality of life. However, STN DBS did not reduce excessive daytime sleepiness despite reductions in antiparkinsonian medications.

Leucotrienos urinarios en pacientes pediátricos con trastorno respiratorio del sueño secundario a hiperplasia adenoamigdalina / Urinary leukotrienes in pediatric patients with sleep disordered breathing secondary to adenotonsillar hypertrophy

RESUMEN Introducción: El trastorno respiratorio del sueño (TRS) afecta al 2% a 3% de la población pediátrica, siendo la hiperplasia adenoamigdalina (HAA) su principal causa. Se ha observado un aumento en los niveles de leucotrienos excretados en orina (LTU) en estos pacientes, los cuales se correlacionarían con la severidad de la enfermedad. Objetivo: Determinar el nivel de LTU en niños con TRS e HAA antes y después de adenoamigdalectomía (AA), y en controles sanos. Correlacionar los niveles de LTU con los síntomas de TRS. Material y método: Estudio prospectivo. Se incluyeron pacientes con TRS e HAA (n =12) y controles sanos (n =12). Se determinó la concentración de LTU en ambos grupos de forma basal y un mes después de cirugía en el grupo con TRS. Resultados: No hubo diferencias en los niveles de LTU antes y después de AA. Tampoco existieron diferencias entre el grupo control y grupo TRS previo a la cirugía. No se encontró asociación entre LTU y la severidad de síntomas respiratorios. Conclusión: Los LTU no se encuentran elevados en pacientes con TRS e HAA, no disminuyen luego de AA y no se correlacionan con la severidad de los síntomas. La medición de LTU no sería una herramienta útil en la evaluación de pacientes con TRS. Nuevos estudios son necesarios para evaluar el rol de los leucotrienos en esta enfermedad.

ABSTRACT Introduction: Sleep disorder breathing (SDB) affects 2%-3% of the pediatric population, being adenotonsillar hyperplasia (ATH) its main cause. An increase in the levels of urinary leukotrienes (ULT) has been measured in these patients, which could be correlated with the severity of the disease. Aim: To determine the level of ULT in children with SDB and ATH before and after adenotonsillectomy, and healthy controls. To correlate the levels of ULT with symptoms of SDB. Material and method: prospective study. SDB and ATH patients (n =12) and healthy controls (n =12) were included. The concentration of ULT in both groups was determined, before surgery and after a month of surgery. Results: There were no differences in the levels of ULT before and after tonsillectomy in the studied group. There were also no differences between the control group and the SDB group. No association was observed between the level of ULT and the severity of respiratory symptoms. Conclusions: ULT are not elevated in patients with SDB and ATH and they do not decrease after adenotonsillectomy. ULT are not correlated with the severity of the symptoms of SDB. The measurement of ULT would not be a useful tool in the evaluation of patients with SDB. New studies are needed to assess the role of the role of leukotrienes in this disease.

Prospective evaluation of sleep improvement after cubital tunnel decompression surgery.

BACKGROUND: Compromised sleep is a known phenomenon with compressive neuropathies such as carpal tunnel syndrome. However, the prevalence of sleep disturbance with cubital tunnel syndrome (CuTS) and the effect on sleep after ulnar nerve decompression are not well understood. We hypothesized that CuTS results in sleep disturbances and that decompression surgery would result in improvement in overall sleep quality. METHODS: Consecutive patients with electrodiagnostic-proven CuTS indicated for decompression were prospectively enrolled. Demographic data, McGowan grade, electrodiagnostic (electromyography) severity, visual analog scale pain score, the 11-item version of the Disabilities of the Arm, Shoulder and Hand questionnaire, and the Insomnia Severity Index scale data were collected preoperatively and at 2 weeks and 3 months postoperatively. RESULTS: There were 145 patients enrolled, with 97% available at 2 weeks and 72% available at the final 3-month follow-up. Surgical decompression procedures consisted of 102 in situ releases and 43 transpositions. The average preoperative Insomnia Severity Index score for the entire cohort was 10.7, above the threshold for a diagnosis of insomnia, which subsequently improved to 4.1 by final follow-up postoperatively, consistent with resolution of the insomnia. There was no difference in the extent of sleep improvement between in situ decompression and transposition. Similarly, electromyography severity and McGowan grade also did not appear to significantly affect the extent of sleep improvement. CONCLUSION: CuTS decompression surgery, irrespective of surgical type and preoperative severity, resulted in improvement in sleep by the 3 month postoperative visit.

Polysomnographic and pulmonary function changes in patients with sleep problems after septoplasty with turbinectomy.

OBJECT: To compare Polysomnography and Pulmonary function tests before and after Septoplasty with Turbinectomy in patients complaining of nasal obstruction and sleep problems due to deviated septum with hypertrophic inferior turbinate. METHODS: 90 patients underwent Septoplasty with Turbinectomy due to nasal obstruction and sleep problems involved in this study, their sleep quality evaluated by polysomnography before and after the surgery, their pulmonary functions assessed by spirometry before and after the operation. RESULTS: The postoperative pulmonary function values; FVC, FEV1, PEFR and postoperative polysomonographic values; AHI, Snoring index/hour, SpaO2 were higher than the preoperative values, and the results were statistically significant (p-values <0.001). CONCLUSION: Septoplasty with partial inferior turbinectomy might be a useful operation in the management of nasal obstruction and sleep problems that caused by a deviated nasal septum and hypertrophied inferior turbinate.

Influencia del exceso de peso en el éxito de la adenoamigdalectomía en pacientes con hiperplasia adenoamigdalina sintomática / The influence of overweight in the success of adenotonsillectomy in patients with adenotonsillar symptomatic hyperplasia

Resumen Introducción: En población pediátrica con malnutrición por exceso, existe controversia respecto al rol de la hiperplasia adenoamigdalina en la etiología de los trastornos del sueño y de la efectividad de la adenoamigdalectomía sobre dicha sintomatología. Objetivo: Comparar la efectividad de la adenoamigdalectomía entre pacientes pediátricos eutróficos y con malnutrición por exceso sometidos a adenoamigdalectomía por hiperplasia adenoamigdalina, en relación a la disminución de la sintomatología. Materiales y método: Estudio retrospectivo mediante revisión de fichas clínicas entre junio de 2016 y enero de 2017 de pacientes operados de adenoamigdalectomía por hiperplasia adenoamigdalina sintomática. Se clasificaron los pacientes de acuerdo a edad y estado nutricional en 4 grupos y se evaluó la resolución de la sintomatologia mediante interrogación a padres/tutores. Resultados: Se incluyeron 98 pacientes, con una edad media de 6,3 años. 44,9% de los pacientes fueron eutróficos y 55,1% con malnutrición por exceso. El análisis estadístico entre pacientes eutróficos y aquellos con malnutrición no demostró diferencias significativas en relación a la resolución de la sintomatología. Conclusión: La adenoamigdalectomía por hiperplasia adenoamigdalina sintomática se asocia a una reducción de la frecuencia de roncopatía con pausas en pacientes pediátricos, independientemente del estado nutricional.

Abstract Introduction: In pediatric population with malnutrition by excess, the role of the adenotonsillar hyperplasia in the etiology of breathing-related sleep disorders, and the effectivity of the adenotonsillectomy for reducing symptoms remains controversial. Aim: To compare and evaluate the effectiveness of the adenotonsillectomy between eutrophic and malnutrition by excess pediatric patients submitted to adenotonsillectomy by adenotonsillar hyperplasia, regarding to symptoms resolution. Material and method: A retrospective study was performed collecting data from clinical records between June 2016 and January 2017 of patients submitted to adenotonsillectomy by symptomatic adenotonsillar hyperplasia. Patients were assigned to 4 groups according to age and nutrional status and the rate of symptoms resolution was evaluated through interrogation to parents/guardians. Results: We included 98 patients, with an average age of 6.3 years. A 44.9% of patients were eutrophic and 55.1% had malnutrition by excess. Comparing eutrophic and malnutrition by excess patients, no significant differences were observed regarding to symptoms resolution. Conclusion: The adenotonsillectomy by symptomatic adenotonsillar hyperplasia was associated to an amelioration of the rate of snoring and respiratory pauses during sleeping in pediatric patients, independently of the nutritional status.

Sleep quality outcomes after medical and surgical management of chronic rhinosinusitis.

BACKGROUND: Endoscopic sinus surgery (ESS) has been shown to improve sleep in patients with chronic rhinosinusitis (CRS). However, it is unknown how this improvement compares with non-CRS control subjects' sleep, and medically treated CRS patients. METHODS: Patients meeting diagnostic criteria for CRS and controls from the same reference population were recruited from 4 academic centers. Patients chose either medical or surgical treatment. The Pittsburgh Sleep Quality Index (PSQI) was administered to patients before treatment and after 6 months, whereas controls received the PSQI at enrollment. RESULTS: The study population consisted of 187 cases (64 medical and 123 surgical) and 101 controls. Baseline PSQI scores for CRS patients (9.27 ± 4.76) were worse than for controls (5.78 ± 3.25), even after controlling for potential confounding factors such as asthma and allergy (p < 0.001). There was no significant difference in baseline PSQI between patients choosing medical vs surgical treatment. The PSQI score in surgical patients improved from 8.36 ± 5.05 to 7.44 ± 5.09 (p = 0.020). The PSQI score in medical patients demonstrated a nonsignificant increase with treatment from 8.71 ± 4.48 to 9.06 ± 4.80 (p = 0.640). After controlling for allergy and asthma, 6-month PSQI scores in medical patients remained significantly higher than in controls (p = 0.001), whereas a significant difference could not be demonstrated between surgical patients and controls (p > 0.05). PSQI subdomain analysis mirrored the overall findings. CONCLUSION: Patients with CRS report worse sleep compared with controls. Surgically treated CRS patients show significant improvement in PSQI scores, whereas those continuing with medical management fail to improve and remain worse than controls.

Prevalence of Diagnosed Sleep Disorders and Related Diagnostic and Surgical Procedures in Children with Autism Spectrum Disorders.

OBJECTIVE: Sleep disorders are common and important comorbid conditions in children with autism spectrum disorder (ASD) and can contribute to cognitive and behavioral problems. Sleep-disordered breathing (SDB) is a diagnosable and treatable cause of behavioral problems in children. We aimed to quantify the relative risk for children with ASD versus controls of being diagnosed with sleep disorders including SDB and undergoing related diagnostic and surgical procedures. METHOD: This retrospective case-cohort study included 48,762 children with ASD aged 2 to 18 years enrolled in the military health system (MHS) from 2000 to 2013. Children with ASD were matched 1:5 by birthdate, sex, and enrollment time to children without an ASD diagnosis. The MHS database was queried for International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for sleep disorders or ICD-9-CM and Current Procedural Terminology codes for diagnostic and surgical procedures. Relative risks (RR) and 95% confidence intervals (CI) were determined with binary Poisson regression conditional on the match and adjusting for confounders. RESULTS: Children with ASD were at higher risk of receiving any sleep disorder diagnosis (RR: 1.97 [95% CI, 1.91-2.02]) including SDB (RR: 1.96 [95% CI, 1.88-2.05]). Children with ASD also were at increased risk of undergoing polysomnography (RR: 3.74 [95% CI, 3.56-3.93]) and sleep disorder-related surgery (RR: 1.50 [95% CI, 1.46-1.54]). CONCLUSION: Children with ASD are more likely to be given a sleep disorder diagnosis including SDB and are more likely to undergo related diagnostic and surgical procedures compared with controls without ASD.

Breathing pattern in a phase I clinical trial of intraspinal injection of autologous bone marrow mononuclear cells in patients with amyotrophic lateral sclerosis.

The safety of autologous bone marrow mononuclear cells (ABMNC) intraspinal infusion in amyotrophic lateral sclerosis (ALS) patients was evaluated considering breathing and sleep patterns. Patients between 20 and 65 years old were eligible if they had definite ALS, spinal onset, a disease duration between 6 and 36 months, FVC>50%, and a below 90% oxygen saturation (T90) <2% of sleep time. The transplant was performed 6 months after enrollment. ABMNC were infused at thoracic 3-4 level. Eleven patients were included. The REM sleep decreased slightly one year after the cell transplant but not significantly. There were no differences in apnea-hipopnea index, mean oxygen saturation and nadir desaturation evolution. An increase of T90 was observed 180 and 360 days after injection (2.95±1.51% and 4.30±4.10% respectively), although it was not statistically significant. The central drive determined by occlusion pressure (P01) and inspiratory flow showed non-significant differences after one year. Intramedullary injection of ABMNC did not worsen the cortico medullar diaphragmatic pathways.

Improvements in sleep-related symptoms after endoscopic sinus surgery in patients with chronic rhinosinusitis.

BACKGROUND: Sleep impairment is highly prevalent in patients with chronic rhinosinusitis (CRS). Although endoscopic sinus surgery (ESS) has been shown to improve overall patient-reported sleep quality, the postoperative impact on individual sleep symptoms remains unclear. METHODS: Patients with medically-recalcitrant CRS who elected to undergo ESS were prospectively enrolled into a multi-institutional, observational cohort study. Sleep-related symptom severity and treatment outcomes were assessed using the sleep domain questions within the 22-item Sino-Nasal Outcome Test (SNOT-22). RESULTS: A total of 334 participants met criteria and were followed postoperatively for an average of 14.5 ± 4.9 months (mean ± standard deviation [SD]). Mean SNOT-22 sleep domain scores improved from 13.7 ± 6.8 to 7.7 ± 6.6 (p < 0.001). Significant mean relative improvements were reported for "difficulty falling asleep" (45%; p < 0.001), "waking up at night" (40%; p < 0.001), "lack of a good night's sleep" (43%; p < 0.001), "waking up tired" (40%; p < 0.001), and "fatigue" (42%; p < 0.001) scores. A total of 66% of study participants reported postoperative improvement in "lack of a good night's sleep," "waking up tired," and "fatigue"; 62% reported improvement in "waking up at night"; and 58% reported improvement in "difficulty falling asleep." CONCLUSION: Patients with CRS report significant and sustained improvements following ESS in common sleep-related symptoms as assessed by the SNOT-22 sleep domain. Despite these significant improvements, some degree of persistent postoperative sleep impairment was reported. Further study is necessary to determine what factors are associated with continued sleep dysfunction after sinus surgery.
