BACKGROUND: Sleep apnoea is a diagnosed condition in which appurtenances interrupt breathing whilst sleeping. The consequence of obstructive sleep apnoea (OSA) includes road traffic accidents due to drowsiness, systemic hypertension, heart disease, diabetes mellitus and neurocognitive disorders. This condition extends the duration of recovery phase after traumatic brain injury. OBJECTIVE: This study was intended to assess the knowledge and attitude towards OSA and compare it among dental and medical undergraduate students of University Sains Malaysia (USM). METHODS: In this study, a total of 216 clinical undergraduate students (36 from each year; 108 from medical and 108 from dental school) of University Sains Malaysia (USM) Health campus were recruited for the study by non-probability stratified random sampling method. Total study period was October 2017 to October 2018. A self-administered questionnaire was used to assess the sociodemographic status and OSAKA questionnaire was used to assess knowledge and attitude regarding sleep apnoea of the respondents. Descriptive analysis was carried out to assess the knowledge and attitude of OSA amongst dental and medical undergraduate students of USM. The Mann–Whitney U test was carried out to compare the knowledge and attitude of OSA amongst dental and medical undergraduate students of USM. RESULTS: Our study findings revealed that 0.9 %and 6.5 %of the dental undergraduate students and medical undergraduate students could answer all the questions correctly regarding knowledge of OSA. Based on the assessment of the difference between medical and dental students in terms of knowledge towards OSA patients, significant difference was observed at the significance level of 95%, where p <  0.05 but no difference found in attitude towards OSA. However, significant difference was found towards attitude on treating OSA patients p <  0.05. CONCLUSIONS: A difference was observed in the knowledge and attitude on OSA between dental and medical undergraduate students in USM; however, medical undergraduate students had better knowledge and attitude towards OSA than dental students.

Objective: To determine the differences of self-perception of halitosis and oral hygiene practices among the medical and dental undergraduate students. Methodology: A cross-sectional study conducted over duration of 9 months amongst the medical and dental undergraduate students of Bahria University Medical and Dental College. The questionnaires were distributed to 298 students. Questionnaire employed for this study was adopted and modified from the study conducted by Khalid Almas et al. Descriptive statistics were checked by means of percentages and frequency for all variables. Chi-square test was applied to check significant difference among the responses given by the medical and dental undergraduate students. Results: The response rate for the survey was about 85%. 55% of dental and 17 % of medical students were able to smell their breath. About having examination by dentist about 73% of medical students agreed as compared to 53% of dental students. Both medical and dental students preferred having examination done by the dentist. For management of halitosis, dentist was preferred by 62% of the dental students, while 97% of the medical students did not agree. 62% of the dental students preferred using traditional medications, while 82% of the medical students preferred using self-medications for treatment. Conclusion: The results suggest that there is not a high level of agreement among dental and medical students concerning the detection and management of halitosis. Although large percent of the respondents claimed to be aware of dentistry, our findings revealed low level of knowledge and attitude to Dentistry by the medical undergraduate students. Efforts should be made towards closing this knowledge gap to attain effective oral health.

The Impact

OSA (obstructive sleep apnoea) stimulates sympathetic nervous activity and elevates resting HR (heart rate) and BP (blood pressure). In the present study in a cohort of 309 untreated OSA patients, the resting HR and BP during the daytime were correlated with AHI (apnoea/hypopnea index) and compared with patients with R389R (n=162), R389G (n=125) and G389G (n=22) genotypes of the β1-adrenoreceptor R389G polymorphism. We analysed the impact of the genotype on the decline of HR and BP in a subgroup of 148 patients (R389R, n=86; R389G, n=54; G389G, n=8) during a 6-month follow-up period under CPAP (continuous positive airway pressure) therapy during which cardiovascular medication remained unchanged. In untreated OSA patients, we found an independent relationship between AHI and resting HR (β=0.096, P<0.001), systolic BP (β=0.09, P=0.021) and diastolic BP (β=0.059, P=0.016). The resting HR/BP, however, did not differ among carriers with the R389R, R389G and G389G genotypes. CPAP therapy significantly reduced HR [−2.5 (−1.1 to −4.0) beats/min; values are mean difference (95% confidence intervals)] and diastolic BP [−3.2 (−1.5 to −5.0) mmHg]. The decline in HR was more significantly pronounced in the R389R group compared with the Gly389 carriers [−4.1 (−2.3 to −5.9) beats/min (P<0.001) compared with −0.2 (2.1 to −2.6) beats/min (P=0.854) respectively; Student's t test between groups, P=0.008]. Diastolic BP was decreased significantly (P<0.001) only in Gly389 carriers (R389G or G389G) compared with R389R carriers [−5.0 (−2.3 to −7.6) mmHg compared with −2.0 (0.4 to −4.3) mmHg respectively]. ANOVA revealed a significant difference (P=0.023) in HR reduction between the three genotypes [−4.1 (±8.4) beats/min for R389R, −0.5 (±9.3) beats/min for R389G and +1.9 (±7.2) beats/min for G389G]. In conclusion, although the R389G polymorphism of the β1-adrenoceptor gene did not influence resting HR or BP in untreated OSA patients, it may modify the beneficial effects of CPAP therapy on these parameters.

BackgroundIt is current practice to use a single diagnostic sleep study in the diagnostic workup of obstructive sleep apnoea (OSA). However, a relevant night-to-night variability (NtNV) of respiratory events has been reported.MethodsWe evaluated the NtNV of respiratory events in adults with suspected or already diagnosed OSA who underwent more than one diagnostic sleep study. Data sources were PubMed, Cochrane and Embase up to 23 January 2019. Random-effects models were used for evidence synthesis. For moderator analysis, mixed-effects regression analysis was performed. The study was registered with PROSPERO (CRD42019135277).ResultsOf 2143 identified papers, 24 studies, comprising 3250 participants, were included. The mean Apnoea-Hypopnoea Index (AHI) difference between the first and second night was −1.70/hour (95% CI −3.61 to 0.02). REM time differences (first to second night) were significantly positive associated with differences in mean AHI (β coefficient 0.262 (95% CI 0.096 to 0.428). On average, 41% (95% CI 27% to 57%) of all participants showed changes of respiratory events >10/hour from night to night. Furthermore, 49% (95% CI 32% to 65%) of participants changed OSA severity class (severity thresholds at 5/hour, 15/hour and 30/hour) at least once in sequential sleep studies. Depending on the diagnostic threshold (5/hour, 10/hour or 15/hour), on average 12% (95% CI 9% to 15%), 12% (95% CI 8% to 19%) and 10% (95% CI 8% to 13%) of patients would have been missed during the first night due to single night testing.ConclusionWhile there was no significant difference between mean AHI in two sequential study nights on a group level, there was a remarkable intraindividual NtNV of respiratory events, leading to misdiagnosis and misclassification of patients with suspected OSA.

Knowledge And Attitude

Introduction: Obstructive sleep apnea is a relatively common sleep disorder, which leads to multiple sleep arousal and hypoxemia. It also has a significant socioeconomic impact. Dentists can have a role in screening as well as treating apnea by orthodontic devices. No study has evaluated the knowledge and attitude of dental health professionals about obstructive sleep apnea (OSA) in Iran. We aimed to measure knowledge and attitude among students and faculty members of Shahid Beheshti Dental School, Tehran, Iran about OSA. Materials and Methods: We conducted a cross-sectional survey among residents and professors in oral and maxillofacial surgery, orthodontics, and oral medicine specialties and dental students. The Obstructive Sleep Apnea Knowledge and Attitude (OSAKA) questionnaire was used to obtain the information regarding knowledge and attitude. We used Chi-square, Kruskall Wallis, Mann-Whitney U test for statistical analysis. The data were analyzed by SPSS 22.0 and a p-value lower than 0.05 considered to be significant. Results: One hundred ninety-seven participants, including 43 dental students, 68 dental residents, and 64 dental professors filled the survey. Mean knowledge score among all participants was 10.69 (SD=3.133). Overall, oral medicine and oral and maxillofacial surgery professors had significantly higher correct answer ratios in the knowledge section than fifth and sixth-year dental students (p<0.001). There was no significant difference among other groups (p>0.05). About attitude, 91% of respondents reported that OSA is an important or extremely important disorder. However, only 10.2% and 16.9% felt confident about the ability to manage patients with OSA and identifying patients at risk for OSA, respectively. Conclusion: All of the participants had poor knowledge but a positive attitude towards OSA. This shows the necessity of better education about OSA.

Objectives: Obstructive sleep apnoea syndrome (OSAS) is a growing health concern as it is associated with serious comorbidities. OSAS is mainly related to obesity, age, gender and a narrowed upper airway is commonly seen in patients with OSAS. This study aimed to compare spirometry parameters between obese OSAS patients and non-obese OSAS patients when patients moved from sitting to supine. Methods: This cross-sectional study was conducted at Sultan Qaboos University Hospital, Muscat, Oman, between December 2009 and December 2010. Patients with severe OSAS and who were OSAS treatment naïve were recruited. Spirometry was performed in all patients in sitting and supine positions to assess forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), FEV1/FVC, forced expiratory flow (FEF) 50%, FEF 25–75%, maximum forced inspiratory flow and expiratory reserve volume. The mean difference in spirometry parameters between patients in sitting and supine positions was calculated. Results: A total of 27 OSAS patients (19 males and 8 females) were included in this study. There was a significant difference in FEV1/FVC in obese and non-obese patients when changing position (P = 0.03). In addition, there was a significant change between male and female patients’ FVC percentages (P <0.05). Male patients with OSAS had reduced FVC compared to females. There was no significant difference in the remaining spirometry parameters with patients’ change of position. Conclusion: A supine position may cause lower airway obstruction in obese patients with OSAS. The reduced FVC in males possibly contributes to the high prevalence of OSAS in men compared to women.Keywords: Obstructive Sleep Apnea; Obesity; Gender; Spirometry; Posture; Oman.

AbstractBackgroundBarbed pharyngoplasty aims to reduce lateral retropalatal obstruction by pulling up the soft palate anterolaterally. However, barbed pharyngoplasty can be less efficient in some cases of obstructive sleep apnoea, especially in the presence of an elongated uvula with redundant tissues over it. This paper describes an attempt to overcome this drawback by modifying barbed pharyngoplasty, using a single continuous suture technique.MethodsThirty-four patients were assigned to two groups based on the surgical procedure performed. Those with an elongated uvula were treated with modified barbed pharyngoplasty (n = 17); the others were treated with barbed pharyngoplasty (n = 17). Pre- and post-operative quality of life questionnaires, and questionnaires concerning diet, pain and return to activity, were completed. Pre- and post-operative polysomnography was performed as an objective measurement.ResultsThere was no significant difference between barbed pharyngoplasty and modified barbed pharyngoplasty in terms of outcomes. However, reductions in the apnoea/hypopnea index, Epworth Sleepiness Scale and snoring visual analogue scale scores were greater in the modified barbed pharyngoplasty group.ConclusionModified barbed pharyngoplasty is a safe and feasible method, and eliminates the need for surgical resection of the redundant soft tissues around the uvula while lifting up the uvula base.

AbstractObjectiveThis study investigated the relationship between disease severity and taste and smell functions in patients with obstructive sleep apnoea syndrome.MethodsA total of 65 patients with recurrent upper airway obstruction during sleep were included. Participants were divided into four groups according to apnoea-hypopnoea index, obtained on polysomnography. Smell and taste tests were performed on these patients.ResultsA significant difference was observed between the smell thresholds of the groups for the identification test (p = 0.016). In the taste test, significant differences were observed between the groups in terms of sweet, sour, salty and bitter taste test thresholds (p = 0.029, p = 0.0005, p = 0.001 and p = 0.017, respectively).ConclusionAs sleep apnoea severity increased (according to the apnoea-hypopnoea index) in obstructive sleep apnoea syndrome patients, the taste and smell thresholds decreased due to the effect of neuropathy and inflammation in the upper respiratory tract.
