[PMID: 34704621 DOI: 10.1002/lary.29916] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2021] [Revised: 10/08/2021] [Accepted: 10/12/2021] [Indexed: 11/12/2022]
Abstract
OBJECTIVES/HYPOTHESIS Adenotonsillectomy (AT) is generally considered the first line treatment for pediatric patients with obstructive sleep apnea (OSA). Pediatric patients with severe OSA have worse outcomes after AT than patients with milder OSA. It is currently unclear if this group of higher morbidity patients should be subdivided further. This study investigates patients with severe pediatric OSA to determine if there are differences in postsurgical outcomes based on initial severity of sleep disordered breathing, medical comorbidities, or demographic factors. STUDY DESIGN Retrospective cohort study at a single tertiary referral center. METHODS Patients aged 2-18 who underwent polysomnogram (PSG) from October 2012 to January 2019, had an apnea-hypopnea index (AHI) >10, and subsequently underwent AT were identified using a filter through electronic medical record. A total of 112 patients underwent both pre- and postoperative PSG. Bivariate analysis was conducted via Pearson chi-square test. Univariate and multivariate analyses via binary logistic and multinomial linear regressions were performed using SPSS. RESULTS Of the 112 patients included in this study, 68 patients were identified as having severe OSA (AHI = 10-20) and 44 as having very severe OSA (AHI > 20). Very severe OSA patients were significantly less likely to be cured of sleep disordered breathing or have their OSA reduced to mild OSA. Obese patients were found to have less reduction in AHI after AT. CONCLUSIONS The postsurgical outcomes of patients with severe and very severe OSA are significantly different indicating that patients traditionally categorized as having severe OSA may need to be further subcategorized.

Abstract
Tonsillar surgery was, from the 19th century, the reference treatment for apneic patients. Adapting to the technical limitations of the time, surgeons devised ingenious procedures. The purpose of this historical note is to travel back to that time and rediscover one of the techniques favored by Chassaignac: "simultaneous enucleation" of the tonsils.

Abstract
A systematic review and meta-analysis is conducted for children with obstructive sleep apnea (OSA) treated with rapid maxillary expansion (RME). The study systematically and independently reviewed extracted articles from 2009 to 2019. The quality evaluation and selection of these studies was based on the high quality of NICE criteria. EMBASE, Scopus and other five databases were used to extract international publications. The findings indicated that the apnea-hypopnea index was enhanced after rapid maxillary expansion among children with OSA. It revealed that apnea hypopnea index enhances to 73% in children with obstructive sleep apnea after ≤ three years follow-up, while it was 77% in children with obstructive sleep apnea after > 3 years. The articles included in this meta-analysis reported differential outcomes based on different inclusion or exclusion criteria and diverse patient populations. Critical evaluation of previous literature suggests diagnosing the disorder at an early stage for reducing the adverse health outcomes and formulating an appropriate treatment plan.

Abstract
SUMMARY Obstructive sleep apnoea syndrome can cause growth delay in children. Adeno-tonsillectomy can resolve the syndrome in most cases. The aim of our study is to examine modifications in clinical and laboratory growth and immunological parameters and food intake changes in OSAS children after surgery. Twenty-eight children with severe OSAS associated with adeno-tonsillar hypertrophy were submitted to paediatric evaluation to calculate auxologic parameters (weight, height, BMI and standard deviation scores), a blood draw to evaluate growth (GH; IGF-1) and immunological parameters (IgG; IgA; IgM) and a dietitian evaluation to calculate caloric intake before and after 3 months following adeno-tonsillectomy. Mean height and weight values in the study group were slightly inferior to same-age children mean according to the percentile values. After surgery, both height and BMI increased significantly at 3-months follow-up: mean height increased 2.93 cm (p = 0.0001); BMI values greatly increased by 0.72 kg/m2 (p = 0.009). Standard deviation scores increased significantly for height (p = 0.03), weight (p = 0.001) and BMI (p = 0.001). These values significantly increased, despite almost unchanged caloric intake between the pre- and post-surgery period (90 ± 24 vs 91 ± 27 kcal/kg/day; p > 0.05). In all children, age-related GH values were normal and did not show any significant increase, while IGF-1 values significantly increased during the study period (p = 0.01). Regarding immunological parameters, only IgA levels decreased after surgery and maintained a value that was higher than normal (> 70 mg/dL). In conclusion, children affected by adenotonsillar hypertrophy and OSAS do not show significant growth delay, but they do experience a slowdown in growth rate. After adeno-tonsillectomy, the speed of growth soon increases, as weight and growth increase notwithstanding an unchanged food intake. Moreover, surgery does not cause reduction in the efficiency of the immune system.

Abstract
PURPOSE We performed an economic evaluation using a decision-tree model to analyze the relative cost effectiveness from the United States Centers for Medicare and Medicaid Services (CMS) perspective of two different methods of tonsillectomy (traditional total tonsillectomy and partial intracapsular) for pediatric obstructive sleep apnea (OSA). MATERIALS AND METHODS Procedural costs were drawn from published literature and Medicare values. Effectiveness and probabilities were drawn from medical literature. Primary intervention was monopolar-technique total tonsillectomy or microdebrider-assisted partial intracapsular tonsillectomy. Secondary interventions included operative control of hemorrhage, treatment of severe dehydration, or revision tonsillectomy. The decision model starts with pediatric patients with OSA, choosing between total and partial tonsillectomy. Outcomes were measured by costs (US dollars), effectiveness [quality-adjusted life year (QALY)], and a willingness-to-pay threshold of US$100,000/QALY. Base case analysis, probabilistic sensitivity analysis (PSA) and deterministic sensitivity analyses were performed. Primary outcome was incremental cost-effectiveness ratio (ICER) for each of the two tonsillectomy techniques. RESULTS Base case analysis demonstrated that total tonsillectomy was more cost effective at US$12,453.40 per QALY gained. In PSA, 82.84% of the simulations show total tonsillectomy to be the more cost-effective strategy. Deterministic sensitivity analyses showed that when the rate of OSA recurrence is lower than 3.12%, partial tonsillectomy would be more cost effective. When the failure rate of partial tonsillectomy is below 1.0%, it is more cost effective even when total tonsillectomy is 100% successful. CONCLUSION Study results suggest that overall monopolar-technique total tonsillectomy is more cost effective. However, with varying adjustments for disutility caused by procedural complications, intracapsular tonsillectomy could become a more cost-effective technique for treating pediatric OSA.

Abstract
OBJECTIVE Fractional time in REM sleep <20% ('little REM sleep') is indicative of more severe sleep-disordered breathing (SDB) in adults. We examined if other REM% is predictive of more severe SDB in children. METHODS In this retrospective study of 616 pediatric SDB patients, age, sex ratio, BMI, sleep efficiency, awakening frequency, sleep latency, apnea-hypopnea index (AHI), obstructive apnea index (OAI), and lowest oxygen pulse saturation (LSpO2) were compared among groups stratified according to REM%: REM≥20%, REM<20%, 15% ≤ REM<20%, 10% ≤ REM<15%, and REM<10%. Correlations with AHI, OAI, LSpO2, sleep efficiency, and awakening frequency were examined in REM<20% and REM<10% groups. Associations of these parameters with REM<10% were examined by single- and multifactor regression. RESULTS Pediatric SDB patients with little REM sleep demonstrated poorer sleep quality than patients with REM≥20%, while patients with REM<10% also exhibited more severe SDB. Specifically, the REM<20% group exhibited higher number of awakenings and lower sleep efficiency than the REM≥20% group (both P ≤ 0.001), as did each REM%<20% subgroup (lower sleep efficiency: all P < 0.05; higher awakening frequency: all P < 0.001). Moreover, compared to the REM≥20% group, the REM<10% also exhibited higher AHI (P = 0.025) and lower LSpO2 (P = 0.019). In the REM<10% group, individual REM% was negatively correlated with AHI (r = -0.216, P = 0.031) and positively with LSpO2 (r = 0.2, P = 0.046). Multifactor logistic regression correcting for age and BMI identified AHI as an independent predictor of REM<10% (P = 0.012, OR = 1.016, 95% CI [1.004,1.029]). CONCLUSION REM% <10% is associated with poor sleep quality and SDB severity in children, suggesting that this threshold should define "little REM sleep" in pediatric patients.

Abstract
INTRODUCTION The optimal surgical technique for the management of patients with Robin Sequence (RS) has not been established. One of the most commonly used surgical techniques, mandibular distraction osteogenesis (MDO), is still controversial because of its potential risks and the lack of clear evidence of its efficacy. OBJECTIVES To assess variations in airway patency, clinical symptoms, and polysomnographic parameters in children with RS who underwent MDO. METHODS In this prospective cohort study, 38 patients with RS were evaluated before and after MDO. Symptom severity was classified using a grading scale for RS clinical manifestations. Patients underwent flexible fiberoptic laryngoscopy, and the images were classified by a blinded examiner using two validated grading scales for airway obstruction. Patients not requiring ventilatory support underwent a polysomnography. RESULTS Patients' symptoms significantly improved after MDO, as shown by a decreased score in the grading scale for RS clinical manifestations (preoperative score of 2.20 vs. postoperative score of 0.81; P < 0.001). The two endoscopic grading scales also showed a statistically significant postoperative improvement in airway obstruction (first scale: preoperative score of 1.56 vs. postoperative score of 0.92; second scale: preoperative score of 2.19 vs. postoperative score of 1.16; P < 0.001 for both). Moreover, there was a statistically significant variation in the following polysomnographic parameters evaluated pre- and postoperatively: apnea-hypopnea index, total sleep time, oxygen desaturation nadir, and oxygen desaturation index (P < 0.05). CONCLUSIONS MDO seems to be an effective surgical option for children, as shown by postoperative improvements in clinical symptoms, endoscopic grading scales, and polysomnographic parameters.

Abstract
OBJECTIVE To investigate choroidal thickness using enhanced-depth imaging optical coherence tomography in paediatric patients with adenotonsillar hypertrophy, with comparison to healthy children, three months after adenotonsillectomy. METHODS The patients were assigned to three groups: an adenotonsillar hypertrophy group, an adenotonsillectomy group and a healthy control group. In all groups, subfoveal, temporal and nasal choroidal thickness measurements were taken. RESULTS In the subfoveal, temporal and nasal regions, choroidal tissue was found to be significantly thinner in adenotonsillar hypertrophy children than healthy children (p = 0.012, p = 0.027 and p = 0.020). The subfoveal and temporal choroidal thickness measurements of adenotonsillar hypertrophy group cases were significantly decreased compared to those in the adenotonsillectomy group (p = 0.038 and p = 0.048). CONCLUSION There was a significant association between decreased choroidal thickness and adenotonsillar hypertrophy. Adenotonsillar hypertrophy may play an important role in decreased choroidal thickness.

Abstract
The efficacy of adenotonsillectomy for treating obstructive sleep apnoea syndrome (OSAS) in children has been established, but its precise effects on inspiratory effort are not well documented.In 353 children enrolled in the Childhood Adenotonsillectomy Trial, randomised to undergo either early adenotonsillectomy (n=182) or a strategy of watchful waiting with supportive care (WWSC) (n=171), thoraco-abdominal asynchrony (TAA) was analysed during quiet, non-apnoeic and non-hypopnoeic breathing during sleep at baseline and at 7 months using overnight polysomnography.Children who underwent early adenotonsillectomy demonstrated a reduction in TAA post-surgery while the WWSC arm showed no change. On assessing TAA with regard to normalisation of clinical polysomnography findings at follow-up, TAA was reduced in children who had surgical resolution of OSAS (based on apnoea–hypopnoea index), but not in children who displayed spontaneous normalisation of apnoea–hypopnoea index. In the latter group, TAA was inversely correlated with quality of life.We conclude that adenotonsillectomy reduces TAA during quiet sleep. Monitoring of instantaneous TAA may yield additional insight in the dynamic changes of inspiratory effort. In combination with traditional indices of obstruction, TAA may more accurately characterise the degree of sleep-disordered breathing in children.

Abstract
In children, moderate or severe sleep-disordered breathing (SDB) may impair cognitive executive functions (EFs), including working memory, attention, and mental flexibility. The main objective of this study was to assess EFs in children with mild levels of SDB. Subjects for this descriptive study were 12 children (5 girls, 7 boys) aged 8.0 to 11.9 years (M = 9.0 ± 0.85) participating in an ongoing study of the effects of adenotonsillectomy on behavior. Each subject had a nocturnal polysomnogram (PSG) and multiple sleep latency test (MSLT). Mild SDB was considered present if the child’s apnea/hypopnea index (AHI) was ≥ 1 and < 10. Between MSLT nap attempts, each child completed standardized tests of EFs. The sample showed significant impairment of sustained attention and vigilance on a computerized continuous performance test. Children with low mental flexibility scores on the Children’s Category Test (CCT) spent more time in stage 1 sleep (12.2% v. 9.5%, P = 0.028 on PSG) and showed a marginally higher arousal index (9.7 v. 6.5, P = 0.06 on PSG) than children with average or above-average CCT scores. AHI accounted for significant proportion of the variance in CCT scores when 1 outlier was removed (N = 11, Rsq = 0.67, P = 0.002). Mild levels of SDB and associated sleep architecture disruptions may be associated with impairment of EFs in children.

Abstract
Sleep disordered breathing (SDB) is characterized by repeated episodes of central or obstructive apneas, disturbing respiratory patterns. The purpose of this study is to quantify respiratory variability associated with apneic/hypopneic events by computing respiratory parameters and thoraco-abdominal asynchrony (TAA) over sleep periods preceding the occurrence of obstructive events in children with SDB. One minute artifact-free epochs of ribcage (RC) and abdominal (AB) signals were extracted from the respiratory inductive plethysmograph (RIP) channel of the PSG prior to the onset of each obstruction. Breath-by-breath values of TAA were computed using a Hilbert transform based technique that measures the phase shift between the RC and AB signals. In addition, the following parameters were computed breath-by-breath from the RC signal: inspiratory time (Ti), expiratory time (Te), total time (Ttot), and the inspiratory duty cycle (DC=Ti/Ttot). Standard deviation of the parameters (SD_TAA, SD_Ti, SD_Te, SD_Ttot, SD_DC) over each 1 min epoch were calculated and averaged over each subject with respect to sleep stage. For comparison, similar measures were computed from within quiet breathing periods of each subject. We found that breaths immediately before apnea/hypopneas were associated with a high degree of variability in respiratory timing and TAA. The proposed variability analysis of RIP signals may be useful for detecting acute epochs of respiratory instability in children with SDB.

Abstract
OBJECTIVES/HYPOTHESIS There is controversy about which children should be admitted after adenotonsillectomy (T&A) and limited clinical evidence to help with this decision. Current practice has evolved based on empirical or anecdotal evidence. We sought to identify practice variations in postoperative admission after T&A in tertiary care pediatric hospitals. STUDY DESIGN Retrospective database study using administrative information stored in the Pediatric Health Information System (PHIS) database. METHODS There were 29,920 T&As performed in 24 pediatric hospitals included in the PHIS database between July 1, 2009 and June 30, 2010. Patients were identified as outpatient (discharged the same day) or inpatient (not discharged on the day of surgery). We examined admission rates across different hospitals stratified by age, obstructive sleep apnea (OSA), and other complex chronic conditions. RESULTS Younger age, the existence of a complex chronic condition, and OSA were all associated with higher post-T&A admission rates. Admission rates ranged from >94% for children under 2 years of age, with OSA and at least one medical comorbidity, to 14% for children older than 5 years, without OSA and without any medical comorbidities. Between-hospital variability was extreme; for example, for 3 to 5 year olds, the admission rate varied from 5% to 90% between hospitals. Very significant variation remained even after controlling for age, comorbidities, and OSA. CONCLUSIONS Post T&A admission rates vary tremendously across comparable tertiary-care pediatric hospitals. There is a crucial need for a better understanding of the risk of complications on the first postoperative night, and the appropriate indications for monitored admission on that night.

Mortality and major morbidity after tonsillectomy: etiologic factors and strategies for prevention. Laryngoscope 2013; 123:2544-53. [PMID: 23595509 DOI: 10.1002/lary.23926] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2012] [Revised: 10/03/2012] [Accepted: 11/08/2012] [Indexed: 12/14/2022]
Abstract
OBJECTIVE/HYPOTHESIS To report data on death or permanent disability after tonsillectomy. STUDY DESIGN Electronic mail survey. METHODS A 32-question survey was disseminated via the American Academy of Otolaryngology-Head and Neck Surgery electronic newsletter. Recipients were queried regarding adverse events after tonsillectomy, capturing demographic data, risk factors, and detailed descriptions. Events were classified using a hierarchical taxonomy. RESULTS A group of 552 respondents reported 51 instances of post-tonsillectomy mortality, and four instances of anoxic brain injury. These events occurred in 38 children (71%), 15 adults (25%), and two patients of unstated age (4%). The events were classified as related to medication (22%), pulmonary/cardiorespiratory factors (20%), hemorrhage (16%), perioperative events (7%), progression of underlying disease (5%), or unexplained (31%). Of unexplained events, all but one occurred outside the hospital. One or more comorbidities were identified in 58% of patients, most often neurologic impairment (24%), obesity (18%), or cardiopulmonary compromise (15%). A preoperative diagnosis of obstructive sleep apnea was not associated with increased risk of death or anoxic brain injury. Most events (55%) occurred within the first 2 postoperative days. Otolaryngologists who reported performing <200 tonsillectomies per year were more likely to report an event (P < .001). CONCLUSIONS This study, the largest collection of original reports of post-tonsillectomy mortality to date, found that events unrelated to bleeding accounted for a preponderance of deaths and anoxic brain injury. Further research is needed to establish best practices for patient admission, monitoring, and pain management. LEVEL OF EVIDENCE N/A.

Abstract
This study aimed to assess the impact of obstructive sleep apnea (OSA) due to adenotonsillar hypertrophy (ATH) on the global myocardial performance in children using tissue Doppler imaging (TDI) and to evaluate the reversibility of the disorder after adenotonsillectomy (AT). The study included 42 children with OSA due to ATH (mean age, 5 ± 3.14 years) as the study group and 45 age- and sex-matched healthy children (mean age, 5.2 ± 3.08 years) as the control group. Polysomnography and echocardiography were performed. Indexed left ventricular mass (LVMi), pulmonary artery systolic pressure, mean pulmonary artery pressure (mPAP), and pulmonary vascular resistance (PVR) were calculated by echocardiography. Tissue Doppler imaging was used to determine the left ventricular and right ventricular myocardial performance index (MPI) of patients and control subjects before and after AT. The patients were classified into mild OSA (apnea-hypopnea index [AHI] 1-5; n = 18)] and moderate to severe OSA (AHI >5; n = 24) according to polysomnography findings. All the children in the control group had an AHI less than 1. They were treated using AT, then reevaluated by polysomnography and echocardiographic examination 6 to 8 months after surgery. Results are described as mean ± standard deviation. The patients with OSA had higher pulmonary artery systolic pressure, mPAP, PVR, LVMi, and right ventricular diastolic diameter than the control subjects. The patients with moderate to severe OSA showed more prominent changes than the patients with mild OSA, but the latter still differed significantly from the control subjects. The TDI-derived right ventricular MPI and left ventricular MPI measurements of the patients with OSA were higher (mean, 0.40 ± 0.08 vs 0.28 ± 0.01; p < 0.001) than those of the control subjects and (0.45 ± 0.05 vs 0.32 ± 0.05; p < 0.001) and correlated well with AHI and mPAP. In addition, mPAP was significantly correlated with AHI. Postoperatively, relief of OSA was validated by polysomnography, and a repeat of the echocardiographic parameters showed no significant differences between the patients and the control subjects. Tissue Doppler imaging can detect the subtle, subclinical changes in cardiac performance that occur in OSA due to adenotonsillar hypertrophy. Such changes generally are reversible after surgical treatment.

Abstract
HYPOTHESIS Adenotonsillectomy improves general and disease-specific quality of life for properly selected patients suffering for upper airway obstruction secondary to adenotonsillar hypertrophy (UAO) and obstructive sleep apnea (OSA). STUDY DESIGN Prospective, nonrandomized questionnaire. SPECIFIC AIMS To evaluate quality of life in patients with UAO and OSA using general quality of life instruments as well as disease-specific instruments. The results will be compared both pre- and postoperatively. METHODS Fifty-five patients aged 2 to 16 with the clinical diagnosis of UAO or OSA were recruited. The caregivers completed Children's Health Questionnaire Parent Form-28 (CHQPF-28) and OSA-18 quality of life measures both pre- and postoperatively in the long and short term. Statistical analysis was performed using the unpaired Student t test, P value less than.05, and Spearman Rank coefficient. RESULTS CHQ-PF28 scores were improved in the Physical Summary parameter in long-term follow-up. Psychosocial scores did not improve significantly. OSA-18 scores showed improvement in both the short-and long-term scores. Physical findings and symptoms did not impact scores in any domain. CONCLUSIONS Quality of life in children with OSA does improve after adenotonsillectomy. Disease-specific clinometric instruments show improvement in domains affected by the disease process. However, instruments used to assess general quality of life may show physical improvement but not psychosocial.

Abstract
Obstructive sleep apnea syndrome (OSA) affects 1%-3% of children. Children with OSA can present for all types of surgical and diagnostic procedures requiring anesthesia, with adenotonsillectomy being the most common surgical treatment for OSA in the pediatric age group. Thus, it is imperative that the anesthesiologist be familiar with the potential anesthetic complications and immediate postoperative problems associated with OSA. The significant implications that the presence of OSA imposes on perioperative care have been recognized by national medical professional societies. The American Academy of Pediatrics published a clinical practice guideline for pediatric OSA in 2002, and cited an increased risk of anesthetic complications, though specific anesthetic issues were not addressed. In 2006, the American Society of Anesthesiologists published a practice guideline for perioperative management of patients with OSA that noted the pediatric-related risk factor of obesity, and the increased perioperative risk associated with adenotonsillectomy in children younger than 3 yr. However, management of OSA in children younger than 1 yr-of-age was excluded from the guideline, as were other issues related specifically to the pediatric patient. Hence, many questions remain regarding the perioperative care of the child with OSA. In this review, we examine the literature on pediatric OSA, discuss its pathophysiology, current treatment options, and recognized approaches to perioperative management of these young and potentially high-risk patients.

Abstract
BACKGROUND Adenotonsillectomy (T&A) is a very common surgical procedure in children. With the rising prevalence of childhood overweight and obesity, our goal was to describe the prevalence of overweight/obesity in children presenting for T&A in our institution. We also sought to compare the frequency of peri-operative complications and the likelihood of being admitted following T&A between overweight/obese and normal weight children. METHODS We examined our peri-operative database and extracted clinical, demographic and anthropometric information on 2170 children who underwent T&A between January 2005 and February 2008. Children were classified into normal weight, overweight and obese using published body mass index (BMI) criteria. The incidences of peri-operative complications were compared between the BMI categories. We also examined factors contributing to the likelihood of admission following T&A. RESULTS The overall prevalence of overweight and obese was 20.7%. Overweight/obese children were more likely to have intra-operative desaturation (p=0.004), multiple attempts at laryngoscopy (p<0.001), difficult mask ventilation (p=0.001), and post-induction and post-anesthesia care unit (PACU) upper airway obstruction (p<0.001). Additionally, overweight and obese children were more likely to be admitted following T&A. BMI showed a moderate positive correlation with post-operative length of stay (LOS). Multiple logistic regression analysis showed that BMI and presence of medical co-morbidities were independent predictors of LOS. CONCLUSION Overweight and obese children presenting for T&A have a higher incidence of peri-operative complications and are more likely to be admitted and stay for longer than their healthy weight peers.

Abstract
Introduction: Obesity affects about 10% to 15% of our school-going population in Singapore and is a risk factor for development of obstructive sleep apnoea hypopnoea syndrome (OSAHS). This article reviews the prevalence, aetiology, pathophysiology, diagnosis, complications and treatment of obese children with OSAHS with particular reference to children in Singapore.
Methods: Review of articles or conference papers reporting data with regards to OSAHS in Singapore children.
Results: Prevalence of OSAHS was high in obese children in Singapore and was more common in males with no racial predisposition. Hypersomnolence as a presenting symptom was uncommon. Cognitive function, behaviour, attention and processing speed was affected and improved after intervention. Abnormalities of glucose metabolism were also found with the respiratory disturbance index (RDI) as an independent predictor of insulin resistance. Tonsillectomy and or adenoidectomy was efficacious as treatment and risk of complications was low. No significant increase in weight occurred post intervention in those enrolled in concurrent weight management programmes.
Conclusions: Prevalence of OSAHS is high in obese Singapore children and many are ‘asymptomatic’. A low threshold for evaluation is necessary for early diagnosis and intervention for prevention of morbidity. Tonsillectomy and/or adenoidectomy is safe and efficacious and remains the first-line treatment in most obese patients.

Abstract
BACKGROUND Obesity is a highly prevalent chronic problem with health and fiscal consequences. Data from adults and nonsurgical pediatric patients suggest that obesity has serious implications for the US economy. OBJECTIVE Our goal was to describe the impact of BMI on hospital charges in children undergoing adenotonsillectomy (AT). METHODS AND PROCEDURES We carried out a retrospective comparative analysis of the electronic anesthesia record and the charges from billing data from a large tertiary institution on children aged 3-18 years who had AT during the year 2005-2007. The main outcome measures were mean total hospital charges, likelihood of admission, and length of hospital stay (LOS). RESULTS Of 1,643 children, 68.9% were aged <10 years, 76% were whites, and 74.1% had private commercial insurance. Most (75.3%) children were discharged on the day of surgery. Obese and overweight children were more likely to be admitted than their normal-weight peers (X(2)=26.3, P<0.001). Among those admitted, BMI showed a positive correlation with LOS (r=0.20, P<0.001). Obese and overweight patients had significantly higher total hospital charges than their healthy-weight counterparts (P=0.001). Anesthesia, postanesthesia care unit (PACU), and pharmacy and laboratory charges were also higher for obese than normal-weight children (P<0.05). DISCUSSION Overweight and obese children undergoing AT accrued higher hospital charges and had longer postoperative LOS than their healthy-weight peers. If these findings are extendable to other surgical procedures, they could have far-reaching implications for the US economy.

Abstract
OBJECTIVE Enlarged tonsils and adenoids (part of Waldeyer's ring) are responsible for obstructive sleep disordered breathing. Obstructive sleep disordered breathing episodes lead to hypoxaemia, hypercapnia and a state of arousal, all of which affect normal development of the nervous system. In this study, two hypotheses were tested: (1) obstructive sleep disordered breathing is caused by adenotonsillar hypertrophy and is associated with hypoxia and brain dysfunction; and (2) children with obstructive sleep disordered breathing more commonly display emotional lability, depressive behaviour and anxiety. MATERIAL AND METHODS A total of 225 children were examined. The study group consisted of 121 children with adenotonsillar hypertrophy (87 aged six to nine years and 34 aged 10 to 13 years) and with obstructive sleep apnoeas and hypopnoeas confirmed by polysomnography. Patients were compared with 104 children with no obstructive sleep disordered breathing and no adenotonsillar hypertrophy (74 aged six to nine years and 30 aged 10 to 13 years). The following tests were used to measure the children's emotional disorders: the children's depression inventory; the state-trait anxiety inventory for children; and the emotional instability scale. The average values and standard deviations were calculated for all results. Student's t-test was used to compare differences in all groups of children. The minimum level of p < 0.05 was set as statistically significant. RESULTS Children with adenotonsillar hypertrophy are more likely to experience poor brain development and sleep problems. They also have emotional disturbances. In the sick and healthy children aged six to nine years, mean results for the emotional instability scale were statistically significantly different in the two groups, being higher in children with adenotonsillar hypertrophy than in healthy children. Mean values for the children's depression inventory test were higher in children with adenotonsillar hypertrophy, but the differences were not statistically significant. In the state-trait anxiety inventory for children test, the mean T score was T = 1.760 and the level of significance was p = 0.08 for both groups. Since the standard level of significance was p < 0.05, the differences in mean values for the state-trait anxiety inventory for children test bordered on statistical significance. There were no differences between tests results in the older children (10 to 13 years). CONCLUSIONS Recent studies have confirmed the negative emotional effect of adenotonsillar hypertrophy induced obstructive sleep disordered breathing in children aged six to nine years. The main problems are emotional lability, and anxiety and depressive disturbances. Such emotional problems subside in older children (aged 10 to 13 years).

Abstract
OBJECTIVE Adenotonsillar hypertrophy (ATH) causing upper airway obstruction and obstructive sleep apnea (OSA) syndrome and may lead to the pulmonary hypertension and cor pulmonale. This study was designed to determine the clinical value of right ventricular (RV) myocardial performance index (MPI) in ATH. The effects of adenotonsillectomy on MPI were also assessed. METHODS Twenty-one children with grade 3 and grade 4 ATH and 21 age-and-sex matched healthy children were enrolled. MPI, defined as the sum of isovolumetric contraction and relaxation time divided by ejection time, was measured by using Doppler echocardiography preoperatively and postoperatively in all subjects. The quality of life in children was also assessed with obstructive sleep disorder questionnaire (OSA-18). RESULTS The RV MPI in patients with ATH was significantly higher than the control group (0.41 +/- 0.06 vs. 0.29 +/- 0.07; P < .001). It showed a strong correlation with mean pulmonary artery pressure and OSA-18 survey score (r = 0.71; P < .005 and (r = 0.64; P < .01, respectively). The RV MPI and OSA-18 survey score decreased significantly after the relief of upper airway obstruction by adenotonsillectomy (from 0.41 +/- 0.06 to 0.31 +/- 0.03; P < .001 and from 83 +/- 27 to 36 +/- 12; P < .0001, respectively). The RV MPI in postoperative group was similar to control group. CONCLUSION Our findings support that advanced stage of ATH is associated with impaired RV functions, which were recovered postoperatively.

Abstract
Management of obstructive sleep apnea syndrome (OSAS) requires a clear understanding of both the medical and surgical components of the treatment and interpretation of the subjective and objective data such as the polysomnagram. Medical management is primarily by continuous positive airway pressure (CPAP) and is the first line of treatment. Surgical management consists of several phases based on the severity and location of the anatomical abnormalities. The last phase of surgical management consists of maxillo-mandibular advancement by a Le Fort I osteotomy and bilateral sagittal split ramus osteotomies of the mandible. The orthognathic procedure is based on the existing skeletal deformity, occlusion and severity of the OSAS. The surgical technique must also take into consideration not only the usual orthognathic principles but the added medical complexity of these patients in the immediate pre and post operative periods.

Abstract
A two and half year old male child was seen with systemic hypertension, left ventricular dysfunction, mitral regurgitation and congestive cardiac failure. Examination revealed adenoid hypertrophy. He was also suffering from obstructive sleep apnea. He was being treated with anti-hypertensive and anti-failure drugs. Adenoidectomy was performed following which obstructive sleep apnea symptoms disappeared and his cardiac status improved markedly. Subsequently he was weaned off anti-hypertensive and anti-failure therapy.

Abstract
OBJECTIVES Obstructive sleep apnoea is a common childhood disorder. Adenotonsillar enlargement is most commonly implicated, with adenotonsillectomy representing an effective treatment in the majority of cases. Such children may develop respiratory compromise post-operatively, sometimes necessitating admission to the intensive care unit. We describe insertion of a nasopharyngeal "prong" airway and evaluate its benefits after adenotonsillectomy for obstructive sleep apnoea and milder forms of sleep-disordered breathing. METHODS The prong is easily fashioned from a paediatric endotracheal tube. It is inserted once surgery is complete, remaining in situ overnight. We retrospectively examine its elective use over an 18-month period in selected children considered to be at high risk of post-operative respiratory compromise. Existing practice over the preceding 18-month period is also examined, by way of comparison. RESULTS Forty-three children underwent adenotonsillectomy for sleep-disordered breathing/OSAS in the 18 months prior to introduction of the prong. Ten were considered "high risk" cases: post-operative intensive care beds were pre-booked for these, but none were eventually required. During the subsequent 18 months, 60 children underwent adenotonsillectomy for the same indication. Seventeen "high risk" cases received the prong post-operatively. No intensive care beds were pre-booked and all children were managed safely on the ENT ward, with minimal intervention. CONCLUSIONS Use of a nasopharyngeal prong significantly improves the post-operative course of selected children who are at high risk of respiratory compromise after adenotonsillectomy. This largely avoids the need for medical intervention and intensive care admission.

Abstract
OBJECTIVE The cardiac complications of adenotonsillar hypertrophy (ATH) have been investigated by many scientists by using supplemental diagnostic modalities such as echocardiography. But, arrhythmia analysis has not been studied adequately in patients with ATH. This study aimed at evaluating the prevalence of arrhythmias, heart rate variability (HRV) and heart rate turbulence (HRT) analyses by means of 24 h Holter ECG monitoring in pre- and post-operative periods in children with ATH. METHODS Twenty-five children with ATH consisting of 12 female and 13 male patients (mean age 66+/-15 months, range 24-108 months) included in this study. All children were assessed pre-operatively and at 1 month post-operatively with 24-h Holter monitoring and ECG analysis. The prevalence analysis of arrhythmias, heart rate variability and heart rate turbulence analysis was assessed. These data were compared. RESULTS Although some ECG and holter findings such as sinusal tachycardia, Mobitz type 1 second-degree AV block improved after the operation, the prevalence of arrhythmias, HRV and HRT values were not changed significantly in post-operative period (p>0.05). CONCLUSION Measurement of HRT and HRV are attractive and easily applicable ways of non-invasive risk prediction of cardiac complications. But, these parameters have not changed significantly in post-operative period. However, ECG and 24-h Holter monitoring of electrocardiography may be useful at evaluating the prevalence of arrhythmias and determining cardiac complications in pre-operative period.

Abstract
OBJECTIVE Sleep apnea is one of the most deleterious disorders in children with adenotonsillar hypertrophy because it can induce hypoxemia of brain. Sleep apnea may lead to failure to thrive or to physical and mental delay in development, including cognitive disturbances. The aim of this study was to analyze the influence of adenotonsillar hypertrophy, causing obstructive sleep apnea on neurocognitive abnormalities. We were interested in sensorimotor coordination, perception, memory, learning ability, concentration, focused attention and language reception. MATERIALS AND METHODS We examined 221 children. One-hundred and seventeen children had sleep apnea caused by adenotonsillar hypertrophy: 87 children aged 6-9 years and 34 children aged 10-13 years. The control group, without adenotonsillar hypertrophy, consisted of 104 healthy children. Both groups of children with and without apnea were examined psychologically to determine abilities and minor neurocognitive deficit. The token test (TT), diagnosis test of brain dysfunction (DCS-test), Luria auditory verbal learning test (LAVLT) and Rey complex figure test (RCFT) were applied to both groups. The tests: TT, DCS-test, RCFT were used to investigate the level of sensorimotor integration and perception processes. Memory and learning abilities were measured using LAVLT. The TT assessed language dysfunction in children. RESULTS This study shows that adenotonsillar hypertrophy in children aged 6-9 years is associated with neurocognitive abnormalities such as: memory problems, concentration of attention deficits, learning disability, language dysfunction, lower sensorimotor integration and perception. The older children (aged 10-13 years) with adenotonsillar hypertrophy had memory problems and learning disabilities. They are likely to be caused by of concentration of attention deficits. The older children were found to have more severe language dysfunction. CONCLUSIONS Our study shows that sleep apnea may lead to neurocognitive deficits. The results may be helpful in the process of making decision for or against surgery in doubtful cases. It is important to know the problems connected with apnea in order to recognize them and help the child develop by providing adequate treatment and cognitive stimulation.

Abstract
Sleep-related breathing disorders and restless legs syndrome have traditionally been felt to affect primarily adults. Recent research suggests that these conditions are surprisingly common in children as well, and that clinical manifestations may differ considerably from those seen in adults. This review summarizes the clinical characteristics, epidemiology, pathophysiology, and treatment of sleep-related breathing disorders and restless legs syndrome in children. Particular emphasis is placed on recent research and on how the presentation and treatment of these conditions are different in children compared with adults.

Abstract
OBJECTIVE Comparison of cardiac function in children with and without adenotonsillar hypertrophy. METHODS We examined 28 pediatric patients with adenotonsillar hypertrophy mean aged 7.3+/-2.9 years comprised of 14 females and 14 males (group I). The control group were chosen from 35 healthy sex and age matched children mean aged 7.37+/-2.7 years (group II). Both groups were examined by an otorhinolaryngologist and adenotonsillar hypertrophy was diagnosed with nasal endoscopic method or lateral neck X-ray. All the patients in group I underwent adenotonsillectomy. Cardiologic and echocardiographic examinations were performed in both groups. Echocardiographic examination was done twice in group I (preoperative and postoperative first month) however in group II only once. Preoperative findings of group I compared with the findings of group II. Preoperative and postoperative echocardiographic findings were also compared within group I. The chi-square test and the independent paired-sample t-test were used for statistical analysis. RESULTS The tricuspid end-diastolic time was the only significant difference in echocardiographic findings between the two groups (104.8+/-28.8 ms versus for 86.4+/-17.32 ms p<0.05). There was no statistical difference between preoperative and postoperative echocardiographic findings in group I. Brady-tachyarrhythmia was detected on electrocardiography - performed with 24h ambulatory electrocardiography - in one patient. To our surprise, in group I five patients had cardiac valve damage: mitral and/or aortic valve insufficiency. These findings were interpreted as silent carditis. CONCLUSION There was no significant difference in right ventricular function between the children with and without adenotonsillar hypertrophy. Whereas, there was shortening of tricuspid end-diastolic time in group I. However, five patients having adenotonsillar hypertrophy developed a cardiac dysfunction which was not observed in the control group. Therefore, we assumed a correlation between adenotonsillar hypertrophy and possible silent carditis following frequent tonsillitis.

Abstract
OBJECTIVES The goal of this review is to provide a synthesis of the current literature addressing the effects of sleep-disordered breathing on cognition and behavior in children aged 2-18. STUDY DESIGN AND SETTING A computerized search was performed to include studies between 1966 and 2001. Studies were assessed based on research question, sampling, intervention, outcomes, confounding, and statistical methods. Sensitivity analyses were performed for quantitative assessments of selection bias, misclassification, and confounding. RESULTS Seventeen reports with 5312 patients were reviewed. The majority of these studies demonstrated poor sampling, insufficient consideration of confounders, and imprecise use of statistical tools. However, there was little evidence of bias in two studies when scrutinized using a sensitivity analysis. CONCLUSIONS Despite suggested links between daytime behavior problems and neurocognitive deficits, there is little certainty for causality based on the quality of the evidence. SIGNIFICANCE By discussing the quality of the current evidence, we hope to improve study design and contribute to the development of an understanding of this complex topic.

Abstract
OBJECTIVE Several studies suggest that a reliable diagnosis of childhood sleep-disordered breathing (SDB) requires polysomnography (PSG). We compared clinical and PSG-based diagnoses in children scheduled for adenotonsillectomy (AT). Parent responses on a validated Pediatric Sleep Questionnaire were used to determine which symptoms could help identify children with clinical diagnoses of SDB but normal PSG. STUDY DESIGN AND SETTING Thirty-four children aged 5.0 to 12.9 years and scheduled for AT to treat clinically diagnosed sleep-disordered breathing underwent laboratory-based PSG. Results were scored by 3 different criteria: 1) >1 obstructive apnea (2 breaths or longer) per hour of sleep; 2) >5 apneas or hypopneas per hour of sleep; or 3) >1 apnea, hypopnea, or respiratory event-related arousal per hour of sleep. RESULTS Depending on the criterion used, the PSG documented SDB from a minimum of 18/34 subjects (53%, for criterion I) to as many as 30/34 subjects (88%, for criterion III). Among symptoms studied, absence of daytime mouth breathing and habitual snoring were most helpful in identification of children who had no evidence of SDB on PSG, by criterion I (Chi-square, P < 0.05). The absence of other common symptoms, such as "loud snoring" or "trouble breathing" at night, were not helpful. CONCLUSION Children with clinical diagnoses of SDB may not consistently meet PSG criteria for this disorder. Questions about daytime mouth breathing and habitual snoring might help clinicians recognize children who would not have SDB on objective testing. SIGNIFICANCE Clinical identification of SDB confirmable on PSG could be improved. However, available outcome data do not yet clarify whether clinical or PSG criteria best identify children likely to suffer morbidity from SDB. EBM RATING C.

Abstract
INTRODUCTION Obstructive sleep apnea syndrome (OSAS) commonly appears in patients with Pierre Robin sequence (PR). Polysomnography (PS) is the gold standard for the diagnosis of OSAS. Videonasopharyngoscopy (VNP) is the best diagnostic tool for visualizing the vocal tract and detecting structural abnormalities which can be associated with OSAS. OBJECTIVE The purpose of this paper is to study whether VNP can be useful for identifying severe OSAS in a population of children with PR. MATERIALS AND METHODS Fifty-two children with PR who were present with sleep-disordered breathing were studied. All the parents completed a questionnaire concerning the children's sleeping habits and sleep complaints before consultation. Each child underwent a general pediatric examination and an evaluation of craniofacial features and upper airway permeability. In all children, a PS was performed. Also, all children underwent a VNP. RESULTS The diagnosis of OSAS was confirmed by PS in 31 patients. VNP showed 87% sensitivity and 100% specificity for the detection of OSAS. VNP findings showed a significant correlation with apnea-hypopnea index, arousal index, snoring time, percentage of sleep time spent at saturation of oxygen <90% and a significant inverse correlation with total sleep time, sleep efficiency and the mean saturation of oxygen during sleep. CONCLUSION This study shows that in children with PR, airway obstruction as detected by VNP seems to be a risk factor for OSAS. VNP appears to be a safe and reliable tool for the evaluation of sleep-disordered breathing in children with PR.

Abstract
OBJECTIVE We present our experience with outpatient tonsillectomy in children and critically review safety to support the outpatient policy. STUDY DESIGN AND SETTING We conducted a retrospective chart review from January 1995 through December 2000 in the pediatric otolaryngology unit of a tertiary care university hospital. RESULTS One thousand two hundred forty-three patients were accepted in the outpatient program with permissive criteria. Postoperative observation time ranged from 3 to 5 hours (median, 4.5 hours). The overall rate of complications was 9.3% (n = 116). Primary and secondary bleeding rates were 6.27% (n = 78) and 0.48% (n = 6), respectively. Thirty-six children (2.9%) had major bleeding; 2 of them were not identified in day-hospital (0.16%). Discharge was delayed in 103 patients (8.3%), and 13 patients showed complications after discharge (about 1% readmission rate). CONCLUSION Our program outcomes support safety. Outpatient surgery is meant to provide comfort to the patient and efficiency to the health care system, without impairing safety; in our experience, most tonsillectomies in children comply with these objectives. SIGNIFICANCE Outpatient tonsillectomy in children may be safe even with permissive criteria, when an appropriate setting is available.

Abstract
Snoring and obstructive sleep apnea are a frequent problem not only in adults, but also in children and adolescents, as can be seen from current epidemiological data. The epidemiology, etiology, diagnosis, and management of obstructive sleep apnea syndrome (OSAS) in adults have been adequately established on the basis of evidential data. As a result of this, both physicians and the public are increasingly aware of OSAS in adults. Although there are numerous parallels between pediatric and adult OSAS, the situation in children differs that in adults. There is a greater variety of symptoms in children with OSAS, diagnosis is often more difficult with serious consequences for growth and development of children. Treatment of OSAS in children is also different from that of the adult patient. There are many possible causes for the development of obstructive sleep apnea in children. These include hypertrophy of the tonsils and syndromes such as Down syndrome, Pickwickian syndrome, Prader-Willi syndrome or Marfan syndrome. OSAS can, however, also be the result of obesity, midfacial dysplasia, retro- or micrognathia, allergic rhinitis or muscular dystrophy. Epidemiological data presented in the literature concerning the incidence of OSAS in children is extremely varied. This wide range is probably due to the fact that snoring may be misdiagnosed as OSAS. The diagnosis of OSAS in children may only be made by considering clinical history (such as rate of growth, tendency to fall asleep during the day, sleep disturbances, susceptibility to infection, etc.), polysomnography (if possible during several nights) and accompanying instrumental diagnosis including cephalometry or laryngoscopy. One of the problems of polysomnography in childhood is that performance and interpretation of the results have not yet been standardized or evaluated for different age groups. Treatment depends on the cause of OSAS and require multidisciplinary management involving the pediatrician, pediatric or adolescent psychiatrist, ear, nose, and throat specialist, maxillofacial surgeons, and neurosurgeons. Adenotonsillectomy (ATE) is the therapy generally chosen if the child has adenoidal vegetations and/or tonsillar hypertrophy. Corrective surgery is possible for rare malformation syndromes. Nocturnal masks for continuous positive airway nasal pressure or procedures for mask respiration are effective in children, but are only used in exceptional cases, such as when ATE is contraindicated or when symptoms of OSAS remain after surgery. The success of pharmacological treatment of OSAS in children has not been evaluated in controlled clinical trials.

Abstract
The causes of obstruction to airflow in the pediatric upper airway include craniofacial disorders, subglottic stenosis, choanal atresia, syndromes associated with neuromuscular weakness, and the most common, hypertrophy of the tonsils and adenoids. Abnormal breathing can adversely affect craniofacial growth, and abnormal craniofacial development can promote upper airway obstruction. Chronic upper airway obstruction often presents with evidence of obstructive sleep apnea syndrome; in severe cases these children also present with pulmonary hypertension and cor pulmonale. The development of pulmonary hypertension and right heart dysfunction from chronic upper airway obstruction is complex. Hypoxemia and hypercarbia-induced respiratory acidosis are potent mediators of pulmonary vasoconstriction that can lead to reversible and irreversible chronic changes in the pulmonary vasculature. It is likely that production of various neurohumoral factors in response to hypoxemia and respiratory distress may further promote pulmonary hypertension, right ventricular dysfunction, and consequent impairment of systemic cardiac output. The anesthetic considerations for children undergoing adenotonsillectomy for chronic airway obstruction are significant. These children are at high risk for complications such as laryngospasm, desaturation, stimulation of pulmonary hypertension and cardiac dysfunction, pulmonary edema, postoperative upper airway obstruction, and respiratory arrest. Because of underlying condition(s) (facial abnormalities, neuromuscular disease, etc.), successful adenotonsillar surgery may not improve upper airway obstruction significantly, especially in the immediate postoperative period when edema, bleeding and the effects of anesthetics and analgesics are present.

Abstract
This study employed a validated pediatric sleep questionnaire to evaluate for sleep-disordered symptoms in children with epilepsy (n=14). Results were compared with those for age-matched children (n=14) with known obstructive sleep apnea. Subjects were enrolled from an outpatient epilepsy clinic and a pediatric sleep disorders clinic. We hypothesized that children with epilepsy would (1) report symptoms of sleep disturbance similar to those of children with documented obstructive sleep apnea, and (2) display behavioral disturbances on parent and child behavioral symptom measures. Results indicate that more than 50% of children with epilepsy had behavioral problems (n=14). No differences in snoring, excessive daytime sleepiness, and restless sleep were seen between the two subject groups. Results suggest that neurobehavioral problems in children with epilepsy may in part be attributed to an underlying sleep disturbance.

Abstract
STUDY OBJECTIVES The Tucson Children's Assessment of Sleep Apnea (TuCASA) study is designed to investigate the prevalence and correlates of objectively measured sleep-disordered breathing (SDB) in preadolescent children. This article describes the parental report of sleep symptoms associated with SDB in Hispanic and white children. DESIGN A 13-question sleep habits screening questionnaire designed to assess the severity of sleep-related symptoms associated with SDB in children 4 to 11 years of age. SETTING Questionnaires were completed by the parents of children attending elementary school in the Tucson Unified School District, Tucson, AZ. PARTICIPANTS There were 1,494 questionnaires returned, which comprised a sample of whites (38%), Hispanics (45%), and other races (17%). Of these questionnaires, 1,214 were returned for the children of white (45.8%; 556 children) or Hispanic (54.2%; 658 children) ethnicity only. The primary analysis was completed on these 613 boys (50.5%) and 601 girls (49.5%). RESULTS In the total sample of 1,494 children, parents were more likely to report excessive daytime sleepiness (EDS) in female children than in male children (p <.01), however, this association did not achieve significance in the sample of only white and Hispanic children (p <.07). Composite variables for EDS and witnessed apnea (WITAP) show that parents of Hispanic children were more likely to report EDS (p <.01) and WITAP (p <.007). Hispanic children were also more likely to have learning problems (LPs) [p <.03] and to snore frequently (SN) [p <.02] than were white children. There were no significant differences between boys and girls for SN or WITAP. Hispanic boys were more likely to have reports of EDS (p <.02) and LPs (p <.04) than white boys, however, there were no other significant differences in gender or ethnicity in reports of EDS or LPs for white or Hispanic boys and girls. Those children with frequent LPs were significantly more likely to have SN (p <.001), EDS (p <.001), and WITAP (p <.001). A logistic regression model predicting LP resulted in significant adjusted odds ratios (ORs) of 2.4 for SN, 2.5 for EDS, and 2.1 for children aged 8 to 11 years. A similar model for EDS resulted in significant adjusted ORs of 3.2 for SN, 5.7 for WITAP, and 1.6 for female gender. Ethnicity was not significant in either model. CONCLUSIONS Hispanic children in the population-based TuCASA study experienced more frequent symptoms associated with SDB, such as SN, EDS, WITAP, and LPs, than did white children. Children with LPs are 2.4 times more likely to have SN, 2.5 times more likely to have EDS, and were 2.1 times more likely to be between the ages of 8 and 11 years. Children with EDS were 3.2 times more likely to have SN, 5.7 times more likely to have WITAP, and were 1.6 times more likely to be a girl.

Abstract
Although it may seem that confusion and uncertainty reign in the field of pediatric sleep medicine, the recent realizations that the scope of childhood SDB is wider, the symptomatology is broader, and the prevalence is higher than previously believed are major advances. Likewise, recent acknowledgment of the lack of true "gold standards" for diagnosing UARS and OSAS in children is also a major advancement in this field. Critical assessment of the current "state of the art" by the 2002 AAP Technical Report on the Diagnosis and Management of Childhood Obstructive Sleep Apnea Syndrome [37] is another major advance that sets the stage for the next steps. The field needs an evidence-based definitions conference, standardization of definitions across all research studies, and much more research on clinical features, pathophysiology, diagnosis, and treatment of the "new" obstructive SDB, including the full range of morbidity caused by increased upper airway resistance. This should include further inquiry into the origins of adult morbidity that resulted from childhood SDB and how it can be prevented.

Abstract
OBJECTIVE To determine the current practices of preoperative evaluation, surgical techniques, and postoperative treatment of pediatric adenotonsillectomy. STUDY DESIGN Forty-one-item survey measuring the frequency of different evaluations, procedures, and treatments performed, including selected case scenarios, with all items scored on a five-point ordinal scale ranking frequency. METHODS The entire membership of the American Society of Pediatric Otolaryngology (ASPO) and active fellows and members of the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) residing in New York state were anonymously surveyed through mail-in questionnaires. RESULTS History alone was the most frequent modality for diagnosing both adenoid enlargement and obstructive sleep apnea. The most common preoperative laboratory test ordered before an adenotonsillectomy is a complete blood cell count; ASPO members ordered fewer preoperative laboratory tests than AAO-HNS members. Unipolar cautery is the most frequently used tonsillectomy technique, and curettage followed by cautery is the most popular adenoidectomy technique. Steroids are the most common intraoperative medication administered during an adenotonsillectomy, and office visits remain the most frequently used methods of assessing adenotonsillectomy patients postoperatively. CONCLUSIONS Although there are statistically significant trends uncovered by the survey, the results reflect a lack of consensus regarding adenotonsillectomy management. Further randomized controlled trials or large-scale outcomes projects are much needed to evaluate critically the current practices of pediatric adenotonsillectomies. Additional efforts may also be required to use the information from these studies in effecting changes in actual practice patterns, moving us toward a more evidence-based paradigm of treating pediatric adenotonsillar disease.

Abstract
OBJECTIVE The prevalence of obesity in the pediatric population has risen more than 20% in 25 years. Accordingly, surgical procedures on obese children have become more common. Adenotonsillectomy (AT) remains among the most frequently performed pediatric surgical procedures in the United States. Our objective was to determine if there is an increased complication rate in morbidly obese (MO) children undergoing AT and if elective pediatric intensive care unit (PICU) admission for observation is warranted. METHODS This retrospective study includes postoperative admissions to the PICU over a 4-year period at one hospital. Out of 957 adenotonsillectomies performed by one surgeon, 543 were admitted to the hospital. Fourteen MO children were identified. Using body mass index (BMI; weight in kg/m(2)), as calculated for age appropriate categories, postoperative outcomes of AT in MO children (>95th percentile BMI) were determined. These 14 were electively admitted to the PICU for airway observation. The indication for surgery in these 14 children was obstructive sleep apnea. Ages ranged from 4 to 15 years. There were 11 males and 3 females. RESULTS Two patients required overnight bi-level positive airway pressure (BiPAP) for oxygen desaturation. One patient remained intubated for 10 days. Three patients required supplemental oxygen. Four of these admissions had preoperative polysomnograms (PSGs). CONCLUSIONS Our study concluded that routine PICU admission was not warranted for most MO patients although several required supplemental oxygen, BiPAP, and one required intubation. These interventions can easily be administered in a surgical floor bed. In fact, these results imply that performing this surgical procedure in obese children is not as risky as many believe. Trends were noted for an increased need of airway interventions in children requiring preoperative BiPAP and in those with comorbidities. In this small population, sample AT was performed on the basis of history. This is to serve as a pilot review for a prospective study in which preoperative PSGs would be used to determine potential indicators for elective PICU admission.

Abstract
STUDY OBJECTIVE To determine the prevalence of sleep-related breathing disturbances in a large cohort of school-aged and preschool-aged children of Southern Italy. DESIGN AND SETTING This cross-sectional prevalence study was designed in two phases: a screening phase aimed to identify symptomatic children from a cohort of 1,207 by a self-administered questionnaire, and an instrumental phase for the definition of sleep-related disorders. PATIENTS AND METHODS One thousand two hundred seven children were screened by a self-administered questionnaire. There were 612 female children (51%) and 595 male children (mean age, 7.3 years; range, 3 to 11 years). According to answers, children were classified in three groups: nonsnorers, occasional snorers, and habitual snorers. All habitual snoring children underwent a polysomnographic home evaluation, and those with an oxygen desaturation index > 2 were considered for nocturnal polygraphic monitoring (NPM). Children with an apnea/hypopnea index > 3 received a diagnosis of obstructive sleep apnea syndrome (OSAS). RESULTS A total of 895 questionnaires (74.2%) were returned and scored; 710 children (79.3%) were identified as nonsnorers, 141 children (15.8%) were identified as occasional snorers, and 44 children (4.9%) were identified as habitual snorers. The percentage of male children who were habitual snorers was higher than the percentage of female children who were habitual snorers (6.1% vs 3.7%, respectively; p < 0.09). OSAS was diagnosed in nine children by NPM. CONCLUSION The lower limit of prevalence of OSAS in childhood is 1% (95% confidence interval [CI], 0.8 to 1.2). If we add the five children who underwent adenoidectomy and/or tonsillectomy because of worsening clinical condition and the two children who were shown to have evidence of OSAS on domiciliary oximetry, then the prevalence is 1.8% (higher limit of prevalence; 95% CI, 1.6 to 2.0).
