The accuracy of the stop bang questionnaire in the identification of obstructive sleep apnoea (OSA) with polysomnography as the gold standard in adult patients with symptoms of sleep disordered breathing in a tertiary care centre in South India

Background: Excessive daytime sleepiness is a key symptom in patients with sleep- breathing disorders (SBD) and represents a new major public health issue due to its repercussions. The ESS is a simple and validated method, which measures the probability of falling asleep in a variety of situations. Aims and objectives is to study the accuracy of the Epworth Sleepiness Scale (ESS) questionnaire in the identification of Obstructive Sleep Apnoea (OSA) in patients with symptoms of sleep disordered breathing in a tertiary care centre.Methods: This present study was conducted in the Department of Respiratory medicine, New Medical College, Kota on 70 adult patients who presented with symptoms of Sleep Disordered Breathing and underwent Type 2 Polysomnography after answering Epworth sleepiness score in Hindi Language.Results: Epworth sleepiness scale has predicted excessive day time sleepiness in 60% of study subjects with ESS score more than 10 taken as cut off. Mean value for ESS in the study was 10.78. 35.71% of the patients had severe OSA diagnosed by polysomnography and 30% patients had moderate OSA. Mild OSA was detected in 7.14% patients. Sensitivity of the ESS score >10 in diagnosing OSA was found to be 72.5%. Specificity of the scale was 73.6%.There was significant correlation between ESS score and diagnosis of OSA (p value <0.001).Conclusions: The study concludes that ESS has got good relevance in predicting OSA in patients with sleep disordered breathing.

ObjectiveTo evaluate the outcome of adenotonsillectomy (AT) in a cohort of children with Down syndrome (DS) and obstructive sleep apnoea (OSA).DesignRetrospective, cross-sectional study.SettingTertiary care centre.PatientsChildren with DS and OSA, without previous upper airway (UA) surgery.InterventionsAT and full overnight polysomnography.Main outcome resultsA significant improvement of the obstructive apnoea-hypopnoea index (oAHI) after AT was obtained. No differences in sleep efficiency or sleep fragmentation were found postoperatively. Almost half of the children had persistent OSA (oAHI ≥5/hour).ResultsData are presented as median (lower–upper quartile). Thirty-four children were included, median age 4.0 years (2.7–5.8), body mass index (BMI) z-score 0.81 (−0.46–1.76), and oAHI 11.4/hour (6.5–22.7). The majority presented with severe OSA (58.9%). AT was performed in 22 children, tonsillectomy in 10 and adenoidectomy in two. Postoperatively, a significant improvement of the oAHI was measured from 11.4/hour (6.5–22.7) to 3.6/hour (2.1–9.5) (p=0.001), with a parallel increase of the minimum oxygen saturation (p=0.008). Children with initially more severe OSA had significantly more improvement after UA surgery (p=0.001). Persistent OSA was found in 47.1% of the children.ConclusionsAT results in a significant improvement of OSA in children with DS without a change in sleep efficiency or sleep stage distribution. Severe OSA was associated with a larger reduction of OSA severity. Almost half of the children had persistent OSA, which was not correlated to age, gender or BMI z-score.

Background: The prevalence of both OSA and metabolic syndrome is increasing worldwide, in part linked to the epidemic of obesity. Beyond their epidemiologic relationship, growing evidence suggests that OSA may be causally related to metabolic syndrome. We are only beginning to understand the potential mechanisms underlying the OSA-metabolic syndrome interaction. Objectives were to study the clinical prevalence of obstructive sleep apnoea in metabolic syndrome; and to find risk factors associated with obstructive sleep apnoea (OSA).Methods: 50 patients attending various OPDs of a tertiary care research and referral hospital and found to have metabolic syndrome on the basis of NCEP criteria were selected. These patients were subjected to overnight polysomnography. Parameters such as apnea-hypopnoea index (AHI), respiratory efforts related arousals (RERA), minimum SpO2, pulse rate, blood pressure, and ECG were monitored throughout the study.Results: Central obesity was found in 34 patients, xanthelasmas in 12 patients and xanthomas in 08 patients. Pitting type of pedal oedema was noted in 14 patients. Epworth sleepiness score (ESS) was calculated in all the patients by interviewing them before the polysomnography. Most of the patients have ESS Score more than 11.03 out of 50 patients were found to have AHI<5.20 patients were found to have moderate AHI (AHI 15-30) whereas 22 were found to have severe AHI.Conclusions: Polysomnography provides a valuable tool to access non symptomatic sleep disordered breathing at an early stage in patients with metabolic syndrome.

Introduction: Tonsillectomy is one of the common ENT surgical procedures. Post-tonsillectomy haemorrhage remains a frequent complication which can be potentially life-threatening. The objective of the present study was to calculate the prevalence of haemorrhage following a tonsillectomy at a tertiary care centre. Methods: It was a descriptive cross-sectional study performed by medical chart review of the patients who underwent tonsillectomy from January 2018 to December 2019 at the department of ENT- Head and Neck Surgery of Tribhuvan University Teaching Hospital. Ethical approval was obtained from the institutional review committee (Ref:-282(6-11) E2 076/077). Convenient sampling method was used. All patients of any age who had tonsillectomy for recurrent tonsillitis or tonsillar hypertrophy with or without obstructive sleep apnoea and no missing information on chart review were included in the study. Data were entered in MS-Excel 2007 and analyzed in rate and percentage. Results: Ten (5.18%) out of a total of 193 patients who underwent tonsillectomy had a post tonsillectomy haemorrhage. All 10 (100%) were adults patients, operated for recurrent tonsillitis, and used electrocautery. It was common in male patients 7 (70%). All of the haemorrhages was between a third and sixth postoperative day and were mild in severity. Conclusions: The prevalence of post-tonsillectomy haemorrhage was high at our centre during the study period of two years. It was common in adults, males and surgery done for recurrent tonsillitis using electrocauterization.
