Development and validation of the international pediatric sleep endoscopy scale (IPSES).

OBJECTIVES: To develop and validate a consensus international pediatric sleep endoscopy scale (IPSES) for pediatric drug-induced sleep endoscopy (DISE). METHODS: Existing published DISE ratings scales were reviewed in order to develop a consensus rating scale synthesizing the most common features and adding new elements to address areas of controversy. Samples of 30 de-identified DISE video recordings were reviewed to develop and refine the scale. After the consensus scale was defined, a separate sample of 25 de-identified DISE videos were scored with the new consensus scale by the development group and a panel of independent raters. A weighted kappa statistic was used to quantify the inter-rater and intra-rater reliability of the consensus scale at each anatomic level. RESULTS: Among all raters, intra-rater reliability was most variable for the nasal airway (kappa range 0.33-0.94) and best for the lateral oropharynx (kappa range 0.68-0.95). Inter-rater reliability ranged from 0.43 for the nasal airway to 0.57 at the soft palate. CONCLUSION: The IPSES is a reliable consensus scale that reflects the most common features of existing scales and can be adopted as a universal scoring scale for pediatric DISE.

Analysis of possible risk factors for the severity of paediatric obstructive sleep apnoea syndrome.

PURPOSE: This study aimed to determine the effect of body mass index (BMI) percentile, asthma, sex, and age on the paediatric obstructive sleep apnoea (OSA) severity. Furthermore, to determine the possible predictive role of the BMI percentile and age in severe OSA. METHODS: This retrospective study included 921 children aged 2-18 years diagnosed with OSA by polysomnography. Analysis of Covariance (ANCOVA), Spearman's correlation, Receiver Operating Characteristics (ROC) analyses were performed and area under the curve (AUC) was determined. RESULTS: We observed a significant association between a higher BMI percentile and the severity of OSA (p < 0.001, ρ = 0.15). The correlation also was significant under (p = 0.007, ρ = 0.11) and over 7 (p = 0.0002, ρ = 0.23) years of age. There was no association between the severity of OSA and the presence of asthma (p = 0.9) or sex (p = 0.891), respectively. Age was significantly related to OSA severity (p = 0.01, ρ = 0.08). Although both the BMI percentile (0.59 AUC [0.54-0.65]) and age (0.58 AUC [0.52-0.63]) predicted severe OSA, according to the sensitivity and specificity values of the ROC curve, the association presents a slight clinical relevance. CONCLUSIONS: OSA severity is determined by the BMI percentile and age in children; however, these factors are unsuitable for predicting severe OSA in clinical practice. Based on our results, obesity is also a significant risk factor for OSA in younger children. Our study highlights that older, overweight, and obese children have a higher risk for severe OSA.

International Pediatric Otolaryngology Group (IPOG) consensus on scoring of pediatric Drug Induced Sleep Endoscopy (DISE).

OBJECTIVES: To develop consensus statements for the scoring of pediatric drug induced sleep endoscopy in the diagnosis and management of pediatric obstructive sleep apnea. METHODS: The leadership group identified experts based on defined criteria and invited 18 panelists to participate in the consensus statement development group. A modified Delphi process was used to formally quantify consensus from opinion. A modified Delphi priori process was established, which included a literature review, submission of statements by panelists, and an iterative process of voting to determine consensus. Voting was based on a 9-point Likert scale. Statements achieving a mean score greater than 7 with one or fewer outliers were defined as reaching consensus. Statements achieving a mean score greater than 6.5 with two or fewer outliers were defined as near consensus. Statements with lower scores or more outliers were defined as no consensus. RESULTS: A total of 78 consensus statements were evaluated by the panelists at the first survey - 49 achieved consensus, 18 achieved near consensus, and 11 did not achieve consensus. In the second survey, 16 statements reached consensus and 5 reached near consensus. Regarding scoring, consensus was achieved on the utilization of a 3-point Likert scale for each anatomic site for maximal observed obstructions of <50% (Score 0, no-obstruction), ≥ 50% but <90% (Score 2, partial obstruction), and ≥ 90% (Score 3, complete obstruction). Anatomic sites to be scored during DISE that reached consensus or near-consensus were the nasal passages, adenoid pad, velum, lateral pharyngeal walls, tonsils (if present), tongue base, epiglottis, and arytenoids. CONCLUSION: This study developed consensus statements on the scoring of DISE in pediatric otolaryngology using a modified Delphi process. The use of a priori process, literature review, and iterative voting method allowed for the formal quantification of consensus from expert opinion. The results of this study may provide guidance for standardizing scoring of DISE in pediatric patients.

[The efficacy of STOP-BANG questionnaire in screening of benign snoring and mild obstructive sleep apnea]. / A STOP-BANG kérdoív hatékonysága a benignus horkolás és az enyhe obstruktív alvási apnoe kiszurésében.

INTRODUCTION: Polysomnography is the gold standard for diagnosing sleep-related breathing disorders. Respiratory pulse oximetry can be used for screening, and several pre-screening questionnaires are available to assess the risk of obstructive sleep apnea. STOP-BANG questionnaire is simple and effective according to the literature. OBJECTIVE: Investigating the effectiveness of the STOP-BANG questionnaire for screening benign snoring and mild obstructive sleep apnea. METHOD: We analyzed the data of patients examined in our department for suspected sleep-related breathing disorder between 20. 06. 2021 and 19. 03. 2022. We compared the subsequently calculated STOP-BANG scores to the respiratory pulsoximetry results. Due to the lack of information regarding the intensity of snoring, the analysis was performed both with positive and negative results for this criterion. Sensitivity, specificity, positive and negative predictive values were calculated. RESULTS: We analyzed the data of 36 patients, one of them was examined twice due to weight loss. Benign snoring was confirmed by 19 patients, mild obstructive sleep apnea in 9, moderate in 4, and severe in 5 cases. Assuming loud snoring, the sensitivity was 100%, the specificity 21%, the positive predictive value 29%, and the negative predictive value 100%. Assuming no loud snoring, the sensitivity was 100%, the specificity 54%, the positive predictive value 41%, and the negative predictive value 100%. CONCLUSION: STOP-BANG questionnaire is effective, and can also be used in primary care to screen benign snoring and mild obstructive sleep apnea. Unnecessary device tests can be reduced by using it, resulting in significantly shorter waiting times for the sleep tests for high-risk patients. Orv Hetil. 2023; 164(7): 265-272.

Peritonsillar abscess: an 8-year retrospective, culture based evaluation of 208 cases.

Introduction. Peritonsillar abscess (PTA) is a common infection which requires surgical intervention and suitable antibiotic therapy.Hypotheses/Gap Statement. Beside Streptococcus pyogenes and Fusobacterium necrophorum several other mostly anaerobic bacteria can be cultured from the properly taken pus samples of PTA, the clinical significance of which is still not fully understood.Aim. This study focused on the culture-based microbiological evaluation of PTA cases, compared to surgical intervention and empirical antibiotic management.Methodology. A retrospective analysis of PTA cases was performed between 2012 and 2019. Data about the aerobic and anaerobic culture results of the samples taken during different surgical interventions were summarized and the coverage of the empirically selected antibiotics was evaluated. The patient's history, the development of complications and the recurrence rate were also evaluated.Results. The microbiological culture results were available for 208 of 320 patients with clinically diagnosed PTA. Incision and drainage (I and D) and immediate tonsillectomy were the leading surgical interventions. Ninety-five Fusobacterium species (including 44 Fusobacterium necrophorum), 52 Actinomyces species and 47 Streptococcus pyogenes were obtained from PTA samples alone or together with polymicrobial flora. S. pyogenes (33.7 %, n=28) and F. necrophorum (22.9 %, n=19) were the dominating pathogens in the 83 monobacterial PTA samples. In >60 % of the patients polymicrobial infection was demonstrated, involving a great variety of anaerobic bacteria. In 22 out of 42 cases where intravenous cefuroxime was empirically started, the therapy should be changed to properly cover the culture-proven anaerobic flora. There were no serious complications, abscess recurrence was detected in two cases (0.96 %).Conclusion. PTAs are often polymicrobial infections including a great variety of anaerobes. Targeted antibiotic therapy, in conjunction with adequate surgical drainage eliminating the anaerobic milieu, can accelerate the healing process and radically reduce the complication and recurrence rate.

Increased behavioral problems in children with sleep-disordered breathing.

BACKGROUND: Healthy sleep is essential for the cognitive, behavioral and emotional development of children. Therefore, this study aimed to assess the behavioral consequences of sleep disturbances by examining children with sleep-disordered breathing compared with control participants. METHODS: Seventy-eight children with SDB (average age: 6.7 years (SD = 1.83); 61 had OSA and 17 had primary snoring) and 156 control subjects (average age: 6.57 years (SD = 1.46) participated in the study. We matched the groups in age (t(232) = 0.578, p = 0.564) and gender (χ2(1) = 2.192, p = 0.139). In the SDB group, the average Apnea-Hypopnea Index was 3.44 event/h (SD = 4.00), the average desaturation level was 87.37% (SD = 6.91). Parent-report rating scales were used to measure the children's daytime behavior including Attention Deficit Hyperactivity Disorder Rating Scale, Strengths and Difficulties Questionnaire, and Child Behavior Checklist. RESULTS: Our results showed that children with SDB exhibited a higher level of inattentiveness and hyperactive behavior. Furthermore, the SDB group demonstrated more internalizing (anxiety, depression, somatic complaints, social problems) (p < 0.001) and externalizing (aggressive and rule-breaking behavior) problems compared with children without SDB, irrespective of severity. CONCLUSIONS: Based on our findings we supposed that snoring and mild OSA had a risk for developing behavioral and emotional dysfunctions as much as moderate-severe OSA. Therefore, clinical research and practice need to focus more on the accurate assessment and treatment of sleep disturbances in childhood, particularly primary snoring, and mild obstructive sleep apnea.

The risk of postoperative respiratory complications following adenotonsillar surgery in children with or without obstructive sleep apnea: A systematic review and meta-analysis.

OBJECTIVES: Obstructive sleep apnea (OSA) appears in 2%-5% of children, with first-line treatment being adenotonsillar (AT) surgery. Our aim was to examine the risk of postoperative respiratory complications (PoRCs) in non-OSA and the different OSA severity (mild, moderate, severe) groups. STUDY DESIGN: We conducted a systematic review and meta-analysis of studies comparing PoRCs following AT surgery in children with and without OSA. METHODS: Nineteen observational studies were identified with the same search key used in MEDLINE, Embase, and CENTRAL. The connection between PoRCs, the presence and severity of OSA, and additional comorbidities were examined. Odds ratios (OR) were calculated with 95% confidence intervals (CI). RESULTS: We found that PoRCs appeared more frequently in moderate (p = 0.048, OR: 1.79, CI [1.004, 3.194]) and severe OSA (p = 0.002, OR: 4.06, CI [1.68, 9.81]) compared to non-OSA patients. No significant difference was detected in the appearance of major complications (p = 0.200, OR: 2.14, CI [0.67, 6.86]) comparing OSA and non-OSA populations. No significant difference was observed in comorbidities (p = 0.669, OR: 1.29, CI [0.40, 4.14]) or in the distribution of PoRCs (p = 0.904, OR: 0.94, CI [0.36, 2.45]) between the two groups. CONCLUSION: Uniform guidelines and a revision of postoperative monitoring are called for as children with moderate and severe OSA are more likely to develop PoRCs following AT surgery based on our results, but no significant difference was found in mild OSA. Furthermore, the presence of OSA alone is not associated with an increased risk of developing major complications.

Postoperative respiratory complications in children with obstructive sleep apnoea syndrome.

Objective: We aimed to prospectively assess the effect of comorbidities on the occurrence of postoperative respiratory complications (PoRCs) after adenotonsillectomy in children with obstructive sleep apnoea syndrome (OSA) and whether otherwise healthy children need a higher level of postoperative monitoring. Methods: 577 children who had OSA and underwent adenotonsillectomy were enrolled. The effects of demographics, comorbidities and OSA on PoRCs were investigated with logistic regression analysis. Results: The PoRC rate was 4.3%. Postoperative oxygen desaturations were more marked in patients with comorbidities (p = 0.005). The presence of comorbidity increased the risk of PoRCs (odds ratio 4.234/3.226-5.241, 95% confidence intervals, p < 0.001). There was no difference in apnoea-hypopnoea index (AHI) values between comorbid patients with and without PoRCs [8.2 (3.8-50.2) vs 14.3 (11.7-23.3)]. (p = 0.37). In the group of patients without comorbidities, PoRCs were associated with a higher AHI [14.7 (3.4-51.3) vs 3.9 (2.0- 8.0), p < 0.001]. Conclusions: Comorbidities are more closely linked with PoRCs than OSA severity. In patients without comorbidity, PoRCs are associated with OSA severity and usually occur within the first 2 hours after the intervention.

Recognizing Early Regulation Disorders in Pediatric Care: The For Healthy Offspring Project.

BACKGROUND Regulation disorders are already apparent in infancy. The For Healthy Offspring Project was the first Hungarian study aimed at building an effective model for screening and examining the prevalence and complex (medical and psychosocial) background of classic behavior regulation disorders (excessive crying, feeding, and sleep problems) in infancy. MATERIAL AND METHODS Data were collected from families of 0- to 3-year-old children in a pediatric hospital and its neighboring areas through questionnaires, medical examinations, and individual and small-group consultations. RESULTS In the questionnaire study about their children's behavior (n=1133), 15% of mothers reported excessive crying, 16% reported feeding problems, and 10% reported sleep problems. In a subsample (n=619) in which medical examinations were also conducted, the prevalence of medical diagnoses was 15.0% for excessive crying, 15.2% for sleep disorders, 10.3% for breastfeeding difficulties, and 14.8% for feeding disorders. Children who were referred to the screening program (n=183) had significantly more behavior regulation disorders than the other children in our study. Regulation disorders were found to be comorbid with other health conditions in some cases. CONCLUSIONS We developed a complex model to screen for regulatory problems in early childhood. This study adds more information about the relationship between regulation problems and other health conditions. The general incidence (5-15%) of early childhood regulation disorders in other countries is likely similar to that found in Hungary. In order to effectively recognize early regulation disorders, diagnostic instruments widely used in the international field should be adapted in general Hungarian pediatric care.

Personalised positive-pressure ventilation in cystic fibrosis / Személyre szabott, pozitív nyomású légzésterápia cystás fibrosisban.

Összefoglaló. A cystás fibrosis az egyik leggyakoribb veleszületett genetikai rendellenesség, elofordulása Magyarországon 1:4000. Az érintett szervekben a mirigyek által termelt nyák emelkedett viszkozitása krónikus gyulladáshoz vezet. A progressziót a pulmonalis folyamat határozza meg, súlyos esetben a tüdotranszplantáció az egyetlen megoldás. A betegek instabil állapota és a hosszú várólista miatt a megfelelo elokészítés kihívásokkal teli, a mutét sokszor sikertelen. A szerzok egy eset segítségével ismertetik a személyre szabott, pozitív nyomású légzésterápia szerepét a transzplantációra való elokészítésben cystás fibrosisban. A 13 éves serdülot csecsemokorában történt jobb tüdocsúcs-reszekciót, majd verejtékvizsgálatot és genetikai tipizálást követoen 8 hónapos korától gondoztuk a Heim Pál Országos Gyermekgyógyászati Intézetben cystás fibrosissal. Fokozatosan romló klinikai állapota miatt 11 éves korától otthoni oxigénterápiát igényelt, 13 éves korára tüdotranszplantáció vált szükségessé. A transzplantációig a légzési munka könnyítése érdekében noninvazív lélegeztetést kezdtünk, melyet a beteg nem tolerált. A rapidan romló általános állapot és légzésfunkció, az inhalatív és szisztémás kezelés ellenére is fennálló folyamatos oxigénigény és jelentos nehézlégzés javítása céljából személyre szabott, pozitív nyomású légzésterápia beállítása történt. Ennek eredményeként 4 vízcentiméteres nyomáson 1 liter/perc oxigén adása mellett a teljes alvásido 100%-a 90% fölötti oxigénszaturációval telt. A kezelést a gyermek jól turte, éjszakái nyugodtabban teltek, általános állapota és légzésfunkciója javult, majd sikeres tüdotranszplantáción esett át. A személyre szabott, pozitív nyomású légzésterápia javítja a cystás fibrosisban szenvedo gyermekek általános állapotát és légzésfunkcióját, ezáltal megkönnyíti a beteg tüdotranszplantáció elotti felkészülését, és növeli a mutét sikerességének esélyét. Orv Hetil. 2021; 162(19): 760-765. Summary. Cystic fibrosis is one of the most common hereditary genetic disorders, the appearance rate of which in the Hungarian population is 1:4000. The increased viscosity of mucus leads to chronic inflammation in the affected organs. The pulmonary manifestation defines the progression, in severe cases lung transplantation is needed. Unstable health condition can make the preparation for surgery difficult and unsuccessful. The role of personalised positive airway pressure therapy prior to lung transplantation in cystic fibrosis is presented through a case report. The 13-year-old child was treated at Heim Pál National Pediatric Institute from the age of 8 months with cystic fibrosis after pulmonary lobectomy, followed by sweat chlorid- and genetic testing. The significant impairment of his general condition required oxygen therapy from the age of 11 years and lung transplantation at the age of 13 years. Until lung transplantation, to relieve the respiratory distress, noninvasive ventilation was started, without success. Considering the rapid progression and persistent need for oxygen - despite inhalation and systemic treatment - personalised positive airway pressure therapy was indicated. At the pressure of 4 cmH2O and an oxygen flow rate of 1 l/min, oxygen saturation was higher than 90% during 100% of the total sleep time. Improvement was registered in both general condition and respiratory function, followed by a successful lung transplantation. In patients with cystic fibrosis, personalized positive airway pressure therapy improves respiratory function, general condition and elevates the success rate of lung transplantation.
