They cause fatigue and drowsiness at the wheel, which can lead to road traffic accidents and even accidents at work. The aim of this study was to assess sleep disorders among professional drivers of oil tankers in Ouagadougou, Burkina Faso. Methods: This was a descriptive and analytical cross-sectional study carried out from 11 April 2020 to 11 September 2020 in the national hydrocarbon company’s fuel depot. All the drivers present at the time were included and accomplished a questionnaire incorporating the commonly scales using to assess sleep disorders, sleep quality and sleep apnoea. Data analysis using R 3.6.1 software enabled to perform univariate and multivariate analyses to identify associated factors. Adjusted odd ratios were used to measure the strength of association. The significance level chosen was p ≤ 0.05. Results: All the 339 respondents were male. A proportion of 33.6% suffered from insomnia, including 12.7% with moderate to severe insomnia, and 18.58% were at risk of sleep apnoea. On the Epworth scale, 26.6% of drivers showed sleep debt and 4.1% excessive daytime sleepiness. The risk factors associated with insomnia were the use of psychostimulants. A history of diabetes and insomnia were risk factors associated with sleep apnoea syndrome. Conclusion: The prevalence of sleep disturbance and insomnia among the respondents were 52.2% and 33.6% respectively. Use of psychostimulants was the identified risk factor. The prevalence of SAS was 4.72%, with diabetes and insomnia as associated factors.展开更多

Obesity, alcohol, smoking and sedatives may contribute to the development of OSA, as well as tonsilar hypertrophy and maxillary and/or mandibular retrognathia. Endocrine conditions such as hypothyroidism and acromegaly have also been reported associated with OSA. Except for excessive daytime sleepiness, headaches and irritability, OSA may lead to hypertension, heart failure, MI and stroke. Management involves reduction of predisposing factors such as obesity and alcohol. Treatment with continuous positive airway pressure (CPAP) is currently most common and best documented. Also uvulopalatopharyngeal surgery and so called phase II surgery, which means advancement of the jaw(s) with orthognatic surgical methods are used. Treatment with dental appliances is getting increasingly popular but the long term outcome remains debatable.展开更多

Surgical treatment has the potential to improve airway patency but when and which surgery should be done is a controversy. <strong>Aims and objective<strong>s</strong></strong><strong>:</strong> To estimate the site of obstruction in patients with OSAS and to assess the surgical results of the site (of obstruction) directed surgical treatment.<strong> Methodology: </strong>Twenty patients with OSAS were included in the study with Eight adults and Twelve children. It was a prospective study. All patients were assessed for the airway collapse and surgery was done accordingly. Repeat PSG was done after surgery for success rate after 4 months of follow up. <strong>Result:</strong> 17 patients successfully completed the follow-up. Four (50%) adults and Two (17%) children have grade I or II tonsils while Four (50%) of adults and Ten (83%) children have tonsil size grade III or IV. Seven (88%) adults and one (8%) of the children have adenoid hypertrophy up to grade II. One adult (12%) and nine children (75%) have grade III Adenoid size. Two children (17%) have Adenoid grade IV size. In Four patients retropalatal more than retroglossal collapse was found (50%). One patient (12%) had retroglossal more than retropalatal collapse other one had only retropalatal collapse, and the other one had retroglossal collapse. ESS (Epworth sleepiness scale) decreased postoperatively in both groups. There is a significant change in AHI with the median pre-op AHI being 40.19 to median post-op AHI being 11.35 with a p-value 0.017. Apnea-hypopnea index (AHI) in children pre-operatively was 12.98 (median) changed to 2.15 (median) which is statistically significant. Only one adult patient (12%) is surgically cured while in five patients (63%) surgical success achieved with a surgical success rate of 5/8 (63%). Whereas only one patient is surgically cured 1/8 (13%). Eight patients achieved surgical success with a total success rate of 8/9 (89%). While only two patients achieved surgical cure (23%) among children. Conclusion: The outcome of site-directed surgical treatment is that it is a satisfactory way of treatment of OSAS with an overall success rate of 76%.展开更多

Obstruction of the upper airway during sleep may result in the generation of noise (snoring), reduction (hypopnoea) or cessation (apnoea) of airflow at the nostrils and mouth. There are multiple indications for undertaking a patient for adenoidectomy and/or tonsillectomy with obstructive sleep apnoea (OSA) being one among many. Objective: The aim of the present study was to find the prevalence of OSA symptoms in children undergoing adenotonsillectomy for indications other than that of obstructive sleep apnoea. Material & Methods: The study was conducted in the Department of ENT and Head & Neck surgery, Gauhati Medical College & Hospital, Guwahati for a period of one year. Twenty six patients who underwent adenoidectomy and/or tonsillectomy during this period were selected for the study. The parents of the patients were administered the Paediatric Sleep Questionnaire pre-operatively and the patients were evaluated for any symptoms of OSA. A score of 8 or more was suggestive of presence of breathing related sleep disorder. All statistical analyses were performed using statistical software SPSS 16.0 version. To test for the difference in the proportion between different variables, chisquare/fisher exact test where appropriate were employed. All statistical tests were two tailed with 0.05 as the threshold level of significance. Results: 11 children (42.3%) had a score of 8 or more out of the 26 children in Paediatric sleep questionnaire. The chi square for this was 4.696 with a p value of 0.096. The snoring subscale was found to be positive in 19 children (73.1%). All children with score of 8 or more were positive for the snoring scale. The sleepiness subscale was found to be positive in 14 children (53.8%). 10 of the 11 children were positive for sleepiness scale among the children who had a score of 8 or more in the questionnaire. These were found to be statistically significant. Conclusion: A significant population of the children undergoing routine adenotonsillectomy also has symptoms of obstructive sleep apnoea. The pathophysiology of obstructive sleep apnoea should be borne in mind in all children having adenotonsillar hypertrophy and a prompt and early intervention into these children should be aimed for both the infective etiology and the possible outcomes of their compromise to the airway column for a better quality of life.展开更多

Methods: Data from referrals to a Prosthodontic Unit from 01-01-2019 to 18-8-2022 were analysed. Results: A total of 240 consecutive referrals to an NHS hospital where a patient was fitted with a mandibular advancement appliance (MAA) were analysed and 160 (67%) were male and 80 (33%) were female. The mean age in years was 52 (2019), 50 (2020), 52 (2021) and 51 (2022). Mean age of male referrals was 51 and female referrals was 53. Conclusion: There are a large number of patients with OSA seeking a dental device and practitioners should be aware of this treatment modality to help the medical team manage OSA. Clinical relevance: Dentists may need to have a greater understanding of OSA and be able to provide MAAs.展开更多

As OSA is a frequent comorbidity in patients with CKD, it is of relevance to evaluate the effect of CPAP treatment on BP in this population. Aim: In this prospective follow-up study, we measured the effect of short term CPAP treatment of moderate-to-severe OSA on brachial and central BP, plasma level of syndecan-1 and vasoactive hormones, renal handling of sodium, subjective sleepiness, and quality of life in patients with impaired renal function. Methods: From December 2015 until March 2017, 25 patients were invited to participate in the study at the University Clinic in Nephrology and Hypertension, Aarhus University and Holstebro Hospital. At baseline and at follow-up after three to four months of CPAP treatment, we performed 24 h brachial and central ambulatory BP measurement, blood sampling measurements of plasma concentrations of syndecan-1, renin, angiotensin II, aldosterone, vasopressin, creatinine, haemoglobin A1c, and cholesterol, cardio respiratory monitoring, 24 h urine collection for measurement of urinary excretion of albumin, aquaporin-2, and epithelial sodium channel, Epworth Sleepiness Scale (ESS), and SF-36 (quality of life). Results: At follow-up, the 17 included patients with mean baseline estimated glomerular filtration rate 66 mL/min/1.73 m2 had a significant decrease in systolic office-, 24 h- and daytime-BP (13, 7, and 8 mmHg, respectively, p Conclusion: Short-term CPAP treatment of patients with moderate-to-severe OSA and reduced renal function decreased 24 h- and daytime-BP significantly and reduced urinary albumin excretion. Our results underline the importance of treatment of OSA in hypertensive patients with impaired renal function.展开更多
