Preventive Medicine Reports Jul 2024Noma is a neglected tropical disease and a global health concern. (Review)
Review
BACKGROUND
Noma is a neglected tropical disease and a global health concern.
OBJECTIVES
To elucidate the epidemiology, management, prevention, and public health implications of Noma.
METHODS
PubMed, Scopus, and Web of Science, supplemented by Google Scholar and World Health Organization databases, were searched using keywords to gather both published and grey literature from 1970 to 2023 in English.
RESULTS
Approximately 30,000-40,000 cases occur annually, with varying incidences across various African countries, such as Nigeria, Niger, and Chad. Incidence in Nigerian and Ethiopian states range from 0.6 to 3300 and 1.64 to 13.4 per 100,000 population, respectively. Mortality is approximately 8.5% in Niger. Risk factors include malnutrition, immunocompromised status, poor dental hygiene, inadequate sanitation, gingival lesions, low socioeconomic status, chronic and infectious diseases, low birth weight, high parity, diarrhoea, and fever. Diagnosis is primarily made based on clinical signs/symptoms and accordingly staging of disease is done. Stage I, II and II presents with acute necrotizing gingivitis, facial edema with halitosis, and necrotizing stomatitis, respectively. If the patient survives acute stages, the progress to Stage IV and Stage V manifests as trismus, difficulty in deglutition and phonation, and facial disfigurement, with increased severity in last stage. Treatment encompasses antibiotic therapy (amoxicillin, metronidazole, chlorhexidine, ampicillin, gentamicin), surgical interventions, wound management (honey dressing, ketamine), and nutritional support. Prevention strategies include oral hygiene, vaccination, health education, and community-based interventions.
CONCLUSION
Noma's recent inclusion in WHO list of neglected tropical diseases is a milestone in recognizing the importance of prevention and early intervention to globally enhance health outcomes.

INTRODUCTION
Dysphagia is a common complication in patients with cervical spinal cord injury (C-SCI) and can cause various pulmonary complications, such as aspiration pneumonia and mechanical airway obstruction increasing mortality and morbidity. This study evaluated the clinical factors that predict dysphagia in patients with traumatic and non-traumatic C-SCI.
METHODS
Ninety-eight patients with C-SCI were retrospectively enrolled in this study and were divided into those with and without dysphagia. Clinical factors such as age, sex, tracheostomy, spinal cord independence measure, pulmonary function test (PFT) including forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and FVC/FEV1, American Spinal Cord Injury Association score, Berg Balance Scale, and surgical approach were investigated retrospectively.
RESULTS
Multivariate logistic regression analysis revealed that FVC and the presence of tracheostomy were significantly correlated with dysphagia in patients with C-SCI ( < 0.05). FVC and the presence of tracheostomy are useful tools for detecting dysphagia in patients with C-SCI.
CONCLUSION
Considering the results of our study, early PFTs, especially FVC, in patients with C-SCI and early initiation of dysphagia management and treatment in patients with C-SCI and tracheostomy will be advantageous in lowering the mortality and morbidity due to pulmonary aspiration in these patients.

Sao Paulo Medical Journal = Revista... 2024The cause of oropharyngeal dysphagia in patients with coronavirus disease (COVID-19) can be multifactorial and may underly limitations in swallowing rehabilitation.
BACKGROUND
The cause of oropharyngeal dysphagia in patients with coronavirus disease (COVID-19) can be multifactorial and may underly limitations in swallowing rehabilitation.
OBJECTIVE
Analyze the factors related to dysphagia in patients with COVID-19 immediately after orotracheal extubation and the factors that influence swallowing rehabilitation.
DESIGN AND SETTING
A retrospective study.
METHODS
The presence of dysphagia was evaluated using the American Speech-Language Hearing Association National Outcome Measurement System (ASHA NOMS) scale and variables that influenced swallowing rehabilitation in 140 adult patients who required invasive mechanical ventilation for >48 h.
RESULTS
In total, 46.43% of the patients scored 1 or 2 on the ASHA NOMS (severe dysphagia) and 39.29% scored 4 (single consistency delivered orally) or 5 (exclusive oral diet with adaptations). Both the length of mechanical ventilation and the presence of neurological disorders were associated with lower ASHA NOMS scores (odds ratio [OR]: 0.80, 95% confidence interval [CI]: 0.74-0.87 P < 0.05; and OR: 0.13, 95% CI: 0.61-0.29; P < 0.05, respectively). Age and the presence of tracheostomy were negatively associated with speech rehabilitation (OR: 0.92; 95% CI: 0.87--0.96; OR: 0.24; 95% CI: 0.80--0.75), and acute post-COVID-19 kidney injury requiring dialysis and lower scores on the ASHA NOMS were associated with longer time for speech therapy outcomes (β: 1.62, 95% CI, 0.70-3.17, P < 0.001; β: -1.24, 95% CI: -1.55--0.92; P < 0.001).
CONCLUSION
Prolonged orotracheal intubation and post-COVID-19 neurological alterations increase the probability of dysphagia immediately after extubation. Increased age and tracheostomy limited rehabilitation.

Long-term follow-up of protective effects on salivary and swallowing structures and improvement of late xerostomia and dysphagia by level IIb optimisation in clinical target volume of nasopharyngeal carcinoma.
BACKGROUND
This study aimed to assess the long-term effect of level IIb clinical target volume (CTV) optimisation on survival, xerostomia, and dysphagia in patients with nasopharyngeal carcinoma (NPC).
METHODS
Clinical data of 415 patients with NPC treated with intensity-modulated radiotherapy between December 2014 and October 2018 were retrospectively analysed. The patients were categorised into modified and comparison groups. Late xerostomia and dysphagia were evaluated using Radiation Therapy Oncology Group/European Organisation for Research and Treatment of Cancer scoring. Survival analysis was performed using the Kaplan-Meier method. Differences in late toxicity and dose parameters between both groups were compared. Prognostic factors for survival and late toxicity were assessed using regression analyses.
RESULTS
Patients in the modified group developed late xerostomia and dysphagia less frequently than those in the comparison group did (P < 0.001). The mean dose (D) and V of parotid glands; D and V of submandibular glands; and D of sublingual glands, oral cavity, larynx, and superior, middle, and lower pharyngeal constrictor muscles were lower in the modified group than those in the comparison group (all P < 0.001). Both groups had no significant differences in overall, local recurrence-free, distant metastasis-free, or progression-free survival. The D of the parotid and sublingual glands was a risk factor for xerostomia. The D of the parotid and sublingual glands and middle pharyngeal constrictor muscle was a risk factor for dysphagia.
CONCLUSIONS
Level IIb optimisation in NPC patients who meet certain criteria specially the exclusion of positive retropharyngeal nodes treated with intensity-modulated radiotherapy has the potential to better protect the salivary and swallowing structures, decreasing the development of late radiation-induced xerostomia and dysphagia while maintaining long-term survival.

BACKGROUND
This study aimed to investigate the trajectories of patient-reported outcomes for individuals who have undergone surgery for oesophageal cancer over a five-year post-surgical period, and to identify modifiable factors that contribute to a decline in quality of life.
METHODS
Patients who underwent resection in Sweden between 2013 and 2020 were included. Data were collected at one-year post-surgery and at regular pre-determined intervals during the five-year post-surgical period. Latent class analysis and logistic regression models were used to identify symptom trajectories and determine their association with lifestyle factors, respectively.
RESULTS
This study included 408 patients, and the majority experienced consistent symptom burdens during the five-year post-surgery period. Current smokers had a higher risk of belonging to the severe dysphagia, severe eating restriction, and severe reflux trajectory. Physically active patients were less likely to belong to the severe dysphagia, severe eating restriction, and severe pain and discomfort trajectory. Patients with a stable weight were less likely to belong to the severe eating restriction and to the recovering body image trajectory.
CONCLUSIONS
Patients who are smokers, have a low level of physical activity, and experience weight loss need further attention and individual support to mitigate long-term symptom burden.

Review
OBJECTIVES
The systematic review aimed to provide an overview of the state-of-art regarding the use of fiberoptic endoscopic evaluation of swallowing (FEES) in pediatrics, specifically investigating FEES feasibility, safety, diagnostic accuracy, and protocols.
METHODS
Four electronic databases were searched for original studies on the pediatric population that instrumentally assessed swallowing function using FEES. A hand-search of the references of included studies was performed. Data on the population, feasibility of endoscope insertion and bolus trials, adverse events, sensitivity and specificity, and FEES equipment and protocol were extracted. The quality of the studies was assessed using the checklists of the Johanna Briggs Institute. Selection of the studies, data extraction, and quality appraisal were conducted by two independent researchers.
RESULTS
Eighty-two reports from 81 studies were included. The mean overall quality of the studies was 80 % (17-100 %). The feasibility of endoscope insertion was high (89%-100 %), while the feasibility of bolus trials varied from 40 % to 100 %. Adverse events were excessive crying (8 studies), irritability or agitation (4 studies), transitory oxygen desaturations (3 studies, 1.2-6.7 % of the patients), epistaxis (3 studies, 0.8-3.3 % of the patients), increased heart rate (1 study, 1 patient), vomiting (1 study, 1 patient), hypertonia (1 study), and hypersalivation (1 study). No major complications were reported. Using VFSS as the reference standard, FEES was generally found to be less sensitive (25-94 %) but more specific (75-100 %) for aspiration, whereas the reverse was true for penetration (sensitivity 76-100 %, specificity 44-83 %). FEES protocols were highly heterogeneous with poor reporting.
CONCLUSION
FEES is a safe, accurate, and generally feasible examination in the pediatric population with suspected dysphagia. However, a consensus on the best FEES protocol for clinical practice and research is currently lacking.

Cervical auscultation is a simple, noninvasive method for diagnosing dysphagia, although the reliability of the method largely depends on the subjectivity and experience of the evaluator. Recently developed methods for the automatic detection of swallowing sounds facilitate a rough automatic diagnosis of dysphagia, although a reliable method of detection specialized in the peculiar feature patterns of swallowing sounds in actual clinical conditions has not been established. We investigated a novel approach for automatically detecting swallowing sounds by a method wherein basic statistics and dynamic features were extracted based on acoustic features: Mel Frequency Cepstral Coefficients and Mel Frequency Magnitude Coefficients, and an ensemble learning model combining Support Vector Machine and Multi-Layer Perceptron were applied. The evaluation of the effectiveness of the proposed method, based on a swallowing-sounds database synchronized to a video fluorographic swallowing study compiled from 74 advanced-age patients with dysphagia, demonstrated an outstanding performance. It achieved an F1-micro average of approximately 0.92 and an accuracy of 95.20%. The method, proven effective in the current clinical recording database, suggests a significant advancement in the objectivity of cervical auscultation. However, validating its efficacy in other databases is crucial for confirming its broad applicability and potential impact.

Understanding the mechanisms underlying dysphagia is crucial in devising effective, etiology-centered interventions. However, current clinical assessment and treatment of dysphagia are still more symptom-focused due to our limited understanding of the sophisticated symptom-etiology associations causing swallowing disorders. This study aimed to elucidate the mechanisms giving rise to penetration flows into the laryngeal vestibule that results in aspirations with varying symptoms. Methods: Anatomically accurate, transparent throat models were prepared with a 45° down flapped epiglottis to simulate the instant of laryngeal closure during swallowing. Fluid bolus dynamics were visualized with fluorescent dye from lateral, rear, front, and endoscopic directions to capture key hydrodynamic features leading to aspiration. Three influencing factors, fluid consistency, liquid dispensing site, and dispensing speed, were systemically evaluated on their roles in liquid aspirations. Results: Three aspiration mechanisms were identified, with liquid bolus entering the airway through (a) the interarytenoid notch (notch overflow), (b) cuneiform tubercle recesses (recess overflow), and (c) off-edge flow underneath the epiglottis (off-edge capillary flow). Of the three factors considered, liquid viscosity has the most significant impact on aspiration rate, followed by the liquid dispensing site and the dispensing speed. Water had one order of magnitude higher aspiration risks than 1% w/v methyl cellulose solution, a mildly thick liquid. Anterior dispensing had higher chances for aspiration than posterior oropharyngeal dispensing for both liquids and dispensing speeds considered. The effects of dispending speed varied. A lower speed increased aspiration for anterior-dispensed liquids due to increased off-edge capillary flows, while it significantly reduced aspiration for posterior-dispensed liquids due to reduced notch overflows. Visualizing swallowing hydrodynamics from multiple orientations facilitates detailed site-specific inspections of aspiration mechanisms.
