Comparative study of virtual and face-to-face training methods on the quality of healthcare services provided by Kermanshah pre-hospital emergency staff (EMS): randomized educational Intervention trial.

BACKGROUND: Emergency medical centers are globally one of the most important pillars of pre-hospital care. The most important purpose of this system is to provide satisfactory services in the shortest possible time and in accordance with the modern scientific standards of the world. The present study aimed to compare the effect of virtual and face-to-face training methods on the quality of service provided by Kermanshah pre-hospital emergency personnel, Iran. METHODS: This was a randomized educational intervention trial performed among the staff of Kermanshah Emergency Medical Center. Individuals were randomly divided into two training groups of virtual and face-to-face. Participants in the face-to-face group received slides, lectures, and practical work with moulage for 6 h a day. Subjects were taught the four skills of intubation, laryngeal mask airway (LMA), cardiopulmonary resuscitation (CPR) and attenuated electrical device (AED). Participants in the virtual group received the same content in the form of a training video on CD with a full explanation of the project's objectives. Pre- and post-test scores of participants were compared within and between the groups by Stata 14.0 software. RESULTS: Eighty-seven individuals were participated in the study, 43 of whom were assigned to the face-to-face training group and 44 to the virtual training group. There was no significant difference between the two groups in terms of work experience and educational level (P > 0.05). Post-training scores in both groups were significantly higher than pre-training in the four skills (P ≤ 0.005). After adjusting for educational level and work experience, however, the quality of CPR, intubation, and AED was higher in the face-to-face training group than in the virtual group. However, the increase in the mean score of LMA in the virtual training was not significantly different than that of the face-to-face training group. CONCLUSION: The results of our study showed the same efficacy of both face-to-face and virtual methods in improving the performance of personnel in tracheal intubation, LMA, CPR and AED shock skills. E-learning methods can be used as a complement to face-to-face methods in education.

European white paper: oropharyngeal dysphagia in head and neck cancer.

PURPOSE: To develop a European White Paper document on oropharyngeal dysphagia (OD) in head and neck cancer (HNC). There are wide variations in the management of OD associated with HNC across Europe. METHODS: Experts in the management of specific aspects of OD in HNC across Europe were delegated by their professional medical and multidisciplinary societies to contribute to this document. Evidence is based on systematic reviews, consensus-based position statements, and expert opinion. RESULTS: Twenty-four sections on HNC-specific OD topics. CONCLUSION: This European White Paper summarizes current best practice on management of OD in HNC, providing recommendations to support patients and health professionals. The body of literature and its level of evidence on diagnostics and treatment for OD in HNC remain poor. This is in the context of an expected increase in the prevalence of OD due to HNC in the near future. Contributing factors to increased prevalence include aging of our European population (including HNC patients) and an increase in human papillomavirus (HPV) related cancer, despite the introduction of HPV vaccination in various countries. We recommend timely implementation of OD screening in HNC patients while emphasizing the need for robust scientific research on the treatment of OD in HNC. Meanwhile, its management remains a challenge for European professional associations and policymakers.

Multilevel radiofrequency ablation to the soft palate and tongue base: tips and pitfalls.

The objective of the study is to increase awareness and understanding of the techniques and safety measures to minimise complications and improve patient outcomes. Literature review using MedLine and keywords snoring; obstructive sleep apnoea; radiofrequency ablation; electrosurgery; palate; tongue base was conducted. There is no accepted gold standard technique for radiofrequency ablation; to date, there is no published literature regarding common tips and pitfalls in radiofrequency application specifically for superficial applications and second-stage surgery. Surgery for snoring and obstructive sleep apnoea is typically multilevel. Pre-operative patient assessment and selection are critical to ensure good outcomes. Radiofrequency is generally safe and efficacious in this subset of patients. However, as with all surgery, it is operator-dependent. In particular, we emphasise the methodology for second-stage surgery, optimising visualisation and avoiding ulceration/fistulation of the soft palate, which are previously undescribed in the literature.

Optimization of Subglottic View During Flexible Laryngoscopy With Patient Positioning.

OBJECTIVE: Determine the ideal head position to optimize visualization of the subglottis using flexible laryngoscopy. STUDY DESIGN: Prospective cohort study. SETTING: Outpatient multidisciplinary airway clinic at a tertiary care center. METHODS: Patients presenting to a multidisciplinary airway clinic undergoing nasoendoscopic airway examination were enrolled. Three head positions were utilized to examine the subglottis during laryngoscopy: "sniffing," chin tuck, and stooping positions. In-office reviewers and blinded clinician participants evaluated views of the airway based on Cormack-Lehane (CL) scale, airway grade (AG), and visual analog scale (VAS). Demographic data were obtained. Statistical analysis compared head positions and demographic data using Student's t test, analysis of variance, and Tukey's post hoc analysis. RESULTS: One hundred patients participated. No statistical differences existed among in-clinic or blinded reviewers for the CL score in any head position (p = .35, .5, respectively). For both AG and VAS, flexed and stooping positions were rated higher than the sniffing positions by both in-clinic and blinded reviewers (p < .01 for all analyses), but there was no statistical difference between these two positions (p = .28, .18, respectively). There was an inverse correlation between age and scores for AG and VAS in the flexed position for both sets of reviewers (p = .02, <.01 respectively), and a higher body mass index was significantly associated with the need to perform tracheoscopy for full airway evaluation (p < .01). CONCLUSION: Both flexion and stoop postures can be implemented by an experienced endoscopist in awake, transnasal flexible laryngoscopy to enhance visualization of the subglottic airway.

Extreme Vocals-A Retrospective Longitudinal study of Vocal Health in 20 Professional Singers Performing and Teaching Rough Vocal Effects.

BACKGROUND: Rough vocal effects, extreme, or extended vocal techniques to sound intentionally hoarse or rough are an integral part of many genres and styles, and research has recently demonstrated the involvement of supraglottic narrowing and vibrations to produce such sounds. The vocal health of singing with rough vocal effects is poorly documented, especially in a longitudinal manner, while much vocal pedagogy continuously treats the sounds as harming to or dangerous for the vocal mechanism. OBJECTIVE: To longitudinally investigate the vocal health of professional singers who perform the five rough-sounding vocal effects Distortion, Growl, Grunt, Rattle, and Creaking as part of their singing and teaching. METHODS: Twenty singers underwent nasoendoscopic examination, filled in SVHI questionnaires, and were assessed by GRBAS with a 14-year interval in a retrospective longitudinal study (from 2007 to 2021). Endoscopic materials were assessed by Reflux Finding Score and a hybrid version of the Stroboscopy Rating Scale. RESULTS: Singers presented at initiation of study with an average SVHI of 9.2 (±9), which decreased at time of follow up 14 years later to an average of 5.12 (±6). Laryngeal assessments (RFS and SRS) revealed low averages at initiation of study as well as at conclusion of the study with only small fluctuations in averages, with findings mainly relating to arytenoid asymmetry. CONCLUSION: The participating singers perform and teach rough vocal effects continually and present with healthy laryngeal mechanisms and within-normal SVHI and GRBAS scores. The findings suggest that controlled supraglottic narrowing and techniques to allow for supraglottic structures to engage in vibration as an additional noise source can be performed sustainable and in a healthy manner if performed with correct vocal technique.

Impact of social deprivation on the outcome of major head and neck cancer surgery in England: A national analysis.

BACKGROUND: Socioeconomic status plays an important role in the incidence and prognosis of many cancers. We examined the relationship between social deprivation and clinical outcomes in patients undergoing major surgery for head and neck cancer. METHODS: A retrospective population-based observational study was performed. Patients undergoing head and neck surgical procedures in England between 2002 and 2012 were identified. This totaled 5051 patients in the less socially deprived (LSD) and 7282 in the more socially deprived (MSD) group. RESULTS: MSD patients were younger (61 vs 63) and were more likely to present with hypopharyngeal-laryngeal cancers (41% vs 30%). They had higher burdens of morbidity and more frequently required emergency surgery (odds ratio [OR] 1.74 [95% CI 1.52-1.99]). Following surgery, MSD patients had higher lengths of inpatient stay (OR 1.72 [95% CI 1.57-1.88]) and higher proportions of both inpatient (OR 1.47 [95% CI 1.19-1.82]) and overall mortality (OR 1.34 [95% CI 1.24-1.45]). CONCLUSION: Increasing socioeconomic deprivation is associated with poor health outcomes in patients with head and neck cancer.

Aortopexy for the treatment of tracheobronchomalacia in 100 children: a 10-year single-centre experience.

OBJECTIVES: Our study describes and analyses the results from aortopexy for the treatment of airway malacia in children. METHODS: Demographic data, characteristics and preoperative, operative and outcome details, including the need for reintervention, were collected for children undergoing aortopexy between 2006 and 2016. RESULTS: One hundred patients [median age 8.2 months, interquartile range (IQR) 3.3-26.0 months] underwent aortopexy. Sixty-four (64%) patients had tracheomalacia (TM) only, 24 (24%) patients had TM extending into their bronchus (tracheobronchomalacia) and 11 (11%) patients had bronchomalacia. Forty-one (41%) children had gastro-oesophageal reflux disease, of which 17 (41%) children underwent a Nissen fundoplication. Twenty-eight (28%) children underwent a tracheo-oesophageal fistula repair prior to aortopexy (median 5.7 months, IQR 2.9-17.6 months). The median duration of follow-up was 5.3 years (IQR 2.9-7.5 years). Thirty-five (35%) patients were on mechanical ventilatory support before aortopexy. Twenty-seven (77%) patients could be safely weaned from ventilator support during the same admission after aortopexy (median 2 days, IQR 0-3 days). Fourteen patients required reintervention. Overall mortality was 16%. Multivariable analysis revealed preoperative ventilation (P = 0.004) and bronchial involvement (P = 0.004) to be adverse predictors of survival. Only bronchial involvement was a predictor for reintervention (P = 0.012). CONCLUSIONS: Aortopexy appears to be an effective procedure in the treatment of children with severe airway malacia. Bronchial involvement is associated with adverse outcome, and other procedures could be more suitable. For the treatment of severe airway malacia with isolated airway compression, we currently recommend aortopexy to be considered.

Prosthetic reconstruction of the trachea: A historical perspective.

This review discusses the history of tracheal reconstruction; from early work to future challenges. The focus is primarily on prosthetic tracheal reconstruction in the form of intraluminal stents, patch repairs, circumferential repairs and replacement of the trachea. A historical perspective of materials used such as foreign materials, autografts, allografts, xenografts and techniques, along with their advantages and disadvantages, is provided.

The influence of stents on microbial colonization of the airway in children after slide tracheoplasty: a 14-year single-center experience.

OBJECTIVES: This study describes the microbial colonization profile of the airway in children after slide tracheoplasty (STP) with and without stents, and compares colonization to children undergoing cardiothoracic surgical procedures without airway related disease. METHODS: A 14-year retrospective single case note review was performed on patients undergoing STP and stent insertion. Nose and throat (NT) and bronchoalveolar lavage (BAL) specimens were analyzed for microbial profile and expressed as cumulative mean microorganisms per patient (MMP). RESULTS: Forty-three patients (median age ± SD 15.02 ± 31.76 months) underwent STP and 141 patients underwent cardiothoracic but no airway surgery (median age ± SD 31.7 ± 47.2 months). Sixteen patients required a stent after STP. One-hundred seventy-two positive microbial specimens were identified. The predominant 6 microorganisms were (1) Staphylococcus aureus; (2) Pseudomonas aeruginosa; (3) Haemophilus influenzae not type B; (4) Coliforms; (5) Streptococcus pneumoniae; and (6) Candida Albicans, and accounted for 128 (74%) of all positive specimens found. Children with stents had more MMP compared to children without stents after STP [4.06 ± 2.38 and 2.04 ± 2.24 MMP (P < 0.001), respectively]. Both groups of children after STP had more MMP compared to the control group (P < 0.001). Children with stents had more microbial colonization of their lower respiratory tract compared to their upper respiratory tract (3.36 ± 2.02 and 1.36 ± 0.93 MMP (P < 0.01) respectively). Staphylococcus aureus colonization of the lower respiratory tract was significantly higher in children with stents compared to children without stents after STP [0.5 and 0.15 MMP (P < 0.05) respectively]. CONCLUSIONS: This study indicates airway surgery and the subsequent use of stents to be a significant risk factor for microbial colonization of the airway in children. More specifically airway stents appear to increase colonization in the distal airway, which appears unrelated to that of the upper respiratory tract.

Towards a classification system for complex craniofacial fractures.

The complexity of facial fractures has changed considerably in recent years together with more commonly observed high velocity trauma. Traditional classification systems describe fractures in an isolated manner but fail to recognise those that affect more than one region. We applied four conceptual scoring systems for craniofacial trauma to a cohort of patients in east London. We exposed the limitations of the systems and developed a new scoring system that encompasses elements of all of the models and is capable of overcoming previous limitations.

Interaction between education and household wealth on the risk of obesity in women in Egypt.

BACKGROUND: Obesity is a growing problem in lower income countries particularly among women. There are few studies exploring individual socioeconomic status indicators in depth. This study examines the interaction of education and wealth in relation to obesity, hypothesising that education protects against the obesogenic effect of wealth. METHODS: Four datasets of women of reproductive age from the Egyptian Demographic and Health Surveys spanning the period 1992-2008 are used to examine two distinct time periods: 1992/95 (N = 11097) and 2005/08 (N = 23178). The association in the two time periods between education level and household wealth in relation to the odds of being obese is examined, and the interaction between the two socioeconomic indicators investigated. Estimates are adjusted for age group and area of residence. RESULTS: An interaction was found between the association of education and wealth with obesity in both time periods (P-value for interaction <0.001). For women with the lowest education level, moving up one wealth quintile was associated with a 78% increase in the odds of obesity in 1992/95 (OR; 95%CI: 1.78; 1.65,1.91) and a 33% increase in 2005/08 (OR; 95%CI: 1.33; 1.26,1.39). For women with the highest level of education, there was little evidence of an association between wealth and obesity (OR; 95%CI: 0.82; 0.57,1.16 in 1992/95 and 0.95; 0.84,1.08 in 2005/08). Obesity levels increased most in women who were in the no/primary education, poorest wealth quintile and rural groups (absolute difference in prevalence percentage points between the two time periods: 20.2, 20.1, and 21.3 respectively). CONCLUSION: In the present study, wealth appears to be a risk factor for obesity in women with lower education levels, while women with higher education are protected. The findings also suggest that a reversal in the social distribution of obesity risk is occurring which can be explained by the large increase in obesity levels in lower socioeconomic groups between the two time periods.

Otogenic cranial base osteomyelitis: a proposed prognosis-based system for disease classification.

OBJECTIVES: To review the presentation, microbiology, and long-term results of treating otogenic cranial base osteomyelitis to develop a prognosis-based disease classification system. PATIENTS AND METHODS: Thirty-eight patients with otogenic cranial base osteomyelitis treated between 1989 and 2002 were studied. Patient demographics, presentation, pathogens, details of therapy, and disease-specific survival were recorded. Patients were stratified using Technetium-99 single-photon emission computerized tomography (SPECT) at presentation into 4 grades: I, mild uptake; II, focal mastoid/temporal bone uptake not reaching midline; III, petrous temporal bone uptake reaching midline; and IV, uptake crossing midline, involving the contralateral temporal bone. Actuarial analysis was used to identify prognostic factors. RESULTS: There were 27 men. The average age at presentation was 65 +/- 16 years (range, 19-95 yr). The median age-adjusted Charlson comorbidity score was 5, and 63% of patients were diabetic. The most common presenting symptoms were pain and otorrhea, and 8 patients had cranial nerve neuropathy. Pseudomonas aeruginosa was the most common bacterial pathogen (n = 28; 74%), and 9 patients had fungal or mixed infections. On average, antibiotics were administered for 161 days, and 6 patients had concomitant surgery. The average follow-up was 33 months, and 3-year disease-specific survival was 76%. Univariate predictors of survival were the SPECT grade, fungal/mixed infections, Charlson score, immune compromise, and cranial nerve neuropathy. The only independent predictor of survival on multivariate Cox regression was the SPECT stage at presentation. CONCLUSION: Cranial base osteomyelitis is associated with significant morbidity and mortality and requires prolonged treatment. Long-term outcome can be predicted from the initial SPECT scan.
