Adhering to Eat and Exercise Status During Radiotherapy for Oropharyngeal Cancer for Prevention and Mitigation of Radiotherapy-Associated Dysphagia.

Importance: Previously published work reported independent benefit of maintenance of oral intake (eat) and swallowing exercise adherence (exercise) during radiotherapy (RT) on diet and functional outcomes. The current study seeks to validate the authors' previously published findings in a large contemporary cohort of patients with oropharynx cancer (OPC) and address limitations of the prior retrospective study using prospective, validated outcome measures. Objective: To examine the longitudinal association of oral intake and swallowing exercise using validated, clinician-graded and patient-reported outcomes. Design, Setting, and Participants: Secondary analysis of a prospective OPC registry including patients who underwent primary RT/chemoradiotherapy (CRT) or primary transoral robotic surgery plus RT/CRT for OPC at a single-institution comprehensive cancer center. Exposures: Adherence to speech pathology swallowing intervention during RT coded as (1) eat: oral intake at end of RT (nothing by mouth [NPO]; partial oral intake [PO], with feeding tube [FT] supplement; full PO); and (2) exercise: swallowing exercise adherence (nonadherent vs partial/full adherence). Main Outcomes and Measures: Feeding tube and diet (Performance Status Scale for Head and Neck Cancer) patient-reported swallowing-related quality of life (MD Anderson Dysphagia Inventory; MDADI) and clinician-graded dysphagia severity grade (videofluoroscopic Dynamic Imaging Grade of Swallowing Toxicity; DIGEST) were collected at baseline, 3 to 6 months, and 18 to 24 months post-RT. Results: A total of 595 patients (mean [SD] age, 65 [10] years; 532 [89%] male) who underwent primary RT (111 of 595 [19%]), CRT (434 of 595 [73%]), or primary transoral robotic surgery plus RT/CRT (50 of 595 [8%]) were included in this cohort study. At the end of RT, 55 (9%) patients were NPO, 115 (19%) were partial PO, 425 (71%) were full PO, and 340 (57%) reported exercise adherence. After multivariate adjustment, subacute return to solid diet and FT were independently associated with oral intake (odds ratio [OR], 2.0; 95% CI, 1.0-4.1; OR, 0.1; 95% CI, 0.0-0.2, respectively) and exercise (OR, 2.9; 95% CI, 1.9-4.5; OR, 0.3; 95% CI, 0.1-0.5, respectively). Subacute MDADI (ß = 6.5; 95% CI, 1.8-11.2), FT duration (days; ß = -123.4; 95% CI, -148.5 to -98.4), and less severe dysphagia per DIGEST (OR, 0.6; 95% CI, 0.3-1.0) were independently associated with oral intake, while exercise was independently associated with less severe laryngeal penetration/aspiration per DIGEST-safety (OR, 0.7; 95% CI, 0.4-1.0). DIGEST grade associations with oral intake were not preserved long-term; however, exercise was associated with a higher likelihood of solid diet intake and better swallow safety per DIGEST. Conclusions and Relevance: The findings of this cohort study extend the authors' previously published findings that oral intake and swallowing exercise during RT are associated with favorable functional outcomes, now demonstrated with broader domains of function using validated measures. Patterns of benefit differed in this study. Specifically, better subacute recovery of swallow-related quality of life and less severe dysphagia were found among patients who maintained oral intake independent of exercise adherence, and shorter FT utilization and better long-term diet and swallowing safety were found among those who exercised independent of oral intake.

Biofeedback eletromiográfico como coadjuvante pode ajudar a manter os resultados da terapia profilática de deglutição em longo prazo na doença de Parkinson? Um estudo piloto / Can adjunctive electromyographic biofeedback help maintain long-term prophylactic swallowing therapy results in Parkinson's disease? A pilot study

RESUMO Objetivo Este estudo piloto teve como objetivo verificar a influência do uso do biofeedback EMG como método coadjuvante para auxiliar na manutenção dos resultados a longo prazo da terapia da deglutição em idosos com doença de Parkinson em uma abordagem profilática. Métodos Os sujeitos foram avaliados quanto ao nível de ingestão oral (Functional Oral Intake Scale - FOIS), qualidade de vida (questionário SWAL-QOL) e videofluoroscopia da deglutição das consistências sólida, pudim e líquida. A gravidade da disfagia foi avaliada por meio do Dysphagia Outcome and Severity Scale (DOSS). Todos os procedimentos foram realizados antes, após três meses e após seis meses do tratamento fonoaudiológico para disfagia orofaríngea. Resultados Três sujeitos foram tratados com terapia fonoaudiológica profilática e três com terapia convencional fonoaudiológica profilática utilizando biofeedback EMG coadjuvante em um total de 18 sessões. Seis pacientes apresentaram melhora nos níveis de ingestão oral, gravidade da disfagia e qualidade de vida após o programa de reabilitação. O nível de ingestão oral foi mantido seis meses após a terapia convencional para dois pacientes e todos os participantes tratados com biofeedback EMG. Conclusão Ambas as modalidades de terapia profilática mostraram melhora na qualidade de vida, nível de ingestão oral e gravidade da disfagia, mas os benefícios foram mantidos ao longo do tempo apenas para os participantes do grupo experimental.

ABSTRACT Purpose This pilot study aimed to verify the influence of using EMG biofeedback as an assisting method to maintain long-term results for swallowing therapy in older adults with Parkinson's disease in a prophylactic approach. Methods: Subjects were evaluated as to the oral intake level (Functional Oral Intake Scale - FOIS), quality of life (SWAL-QOL questionnaire), and videofluoroscopy of swallowing of solid, pudding and liquid consistencies. The severity of dysphagia was assessed using the Dysphagia Outcome and Severity Scale (DOSS). All procedures were performed before, after three months, and after six months of speech-language therapy treatment for oropharyngeal dysphagia. Results: Three subjects were treated with prophylactic speech-language therapy, and three with prophylactic speech-language conventional therapy using adjunctive EMG biofeedback in a total of 18 sessions. Six patients experienced a reduction of the severity of the dysphagia, improved oral intake levels and quality of life after the rehabilitation program. The oral intake level was maintained six months after conventional therapy for two patients and for all participants treated with EMG biofeedback. Conclusion Both therapy modalities with PSLT showed improved quality of life, oral intake level, and reduction of the severity of dysphagia, but the benefits were maintained over time only for participants in the experimental group.

Rehabilitation Nutrition for Injury Recovery of Athletes: The Role of Macronutrient Intake.

An adequate and balanced diet is of utmost importance in recovery and rehabilitation. "Rehabilitation nutrition" for injury recovery of athletes is similar to sports nutrition, except for the differences that concern the prevention of the risk or presence of sarcopenia, malnutrition, or dysphagia. Rehabilitation nutrition also aims, combined with training, to an adequate long-term nutritional status of the athlete and also in physical condition improvement, in terms of endurance and resistance. The aim of this paper is to define the proper nutrition for athletes in order to hasten their return to the sports after surgery or injury. Energy intake should be higher than the energy target in order to fight sarcopenia-that is 25-30 kcal/kg of body weight. Macro- and micro-nutrients play an important role in metabolism, energy production, hemoglobin synthesis, lean mass and bone mass maintenance, immunity, health, and protection against oxidative damage. Nutritional strategies, such as supplementation of suboptimal protein intake with leucine are feasible and effective in offsetting anabolic resistance. Thus, maintaining muscle mass, without gaining fat, becomes challenging for the injured athlete. A dietary strategy should be tailored to the athlete's needs, considering amounts, frequency, type and, most of all, protein quality. During rehabilitation, simultaneous carbohydrates and protein intake can inhibit muscle breakdown and muscle atrophy. The long-term intake of omega-3 fatty acids enhances anabolic sensitivity to amino acids; thus, it may be beneficial to the injured athlete. Adequate intakes of macronutrients can play a major role supporting athletes' anabolism.

Effectiveness of low-level laser therapy for oral mucositis prevention in patients undergoing chemoradiotherapy for the treatment of head and neck cancer: A systematic review and meta-analysis.

Oral Mucositis is a frequent and debilitating inflammatory complication in patients with head and neck malignancies and may lead to unplanned treatment interruptions due to intense pain and dysphagia. This systematic review with meta-analysis was performed to determine the effectiveness of low-level laser therapy in preventing oral mucositis in this context. The following databases were searched through September 2018, with last search performed on May 2019, for clinical trials: MEDLINE via PubMed, Cochrane Central, Scopus, Lilacs, ISI Web of Science and SIGLE via Open Grey. From 14,525 records, 4 studies were included in the review and 3 studies were included in meta-analysis. Data from 500 patients (mean age of 53.595 and 54.14 for intervention and control groups, respectively) were analysed. Meta-analysis showed that laser therapy prevents oral mucositis incidence in 28% and 23% of cases during the third and fourth follow-up week, respectively, in comparison to a placebo-treated control group. There was no statistically significant difference the prevention of pain; dysphagia and quality of life were not analysed due to missing. Laser therapy was effective in preventing oral mucositis from the 15th to the 45th days of chemoradiotherapy. However, new primary studies with low risk of bias are needed so a higher scientific evidence can be obtained.

Nutrition and swallowing therapy strategies for patients with head and neck cancer.

Patients with head and neck cancer experience many problems with eating which make them at high risk of malnutrition. Pre-habilitation swallowing exercises as overseen by a speech pathologist can improve swallowing function. A multidisciplinary approach to care, including effective nutritional screening, assessment and intervention has demonstrated improved outcomes in terms of meet nutritional requirements, improved nutritional status and quality of life. Nutritional recommendations are 1.2-1.5 g protein per kilogram per day and 125kJ/kg body weight per day but as these are guides close monitoring of intake and weight is important. Multidisciplinary teams and telehealth have shown better outcomes for nutrition and swallowing status for head and neck cancer patients and ongoing support is required for best patient care.

A Double-Blind Randomized Controlled Trial to Determine the Preventive Effect of Hangekobokuto on Aspiration Pneumonia in Patients Undergoing Cardiovascular Surgery.

PURPOSE: This study aimed to assess whether hangekobokuto (HKT) can prevent aspiration pneumonia in patients undergoing cardiovascular surgery. METHODS: We performed a single-center, double-blinded, randomized, placebo-controlled study of HKT in patients undergoing cardiovascular surgery. JPS HKT extract granule (JPS-16) was used as HKT. The primary endpoint was defined as the prevention of postoperative aspiration pneumonia. The secondary endpoints included complete recovery from swallowing and coughing disorders. RESULTS: Between August 2014 and August 2015, a total of 34 patients were registered in this study. The rate of subjects with postoperative aspiration pneumonia was significantly lower in the HKT group than in the placebo group (p = 0.017). In high-risk patients for aspiration pneumonia, the rate was significantly lower in the HKT group than in the placebo group (p = 0.015). The rate of subjects with swallowing disorders tended to be lower in the HKT group than in the placebo group (p = 0.091), and in high-risk patients, the rate was significantly lower in the HKT group than in the placebo group (p = 0.038). CONCLUSIONS: HKT can prevent aspiration pneumonia in patients undergoing cardiovascular surgery. In high-risk patients for aspiration pneumonia, HKT can prevent aspiration pneumonia and improve swallowing disorders.

Motor Imagery Practice and Increased Tongue Strength: A Case Series Feasibility Report.

Purpose The aim of the study was to determine the effects of a 6-week progressive resistance tongue exercise protocol in mental practice form on tongue strength. Investigation begins in typically aging adults, a population susceptible to reduced tongue strength and dysphagia secondary to age-related changes in the swallowing mechanism. It was hypothesized that typically aging adults who perform a 6-week progressive resistance tongue exercise protocol in mental practice form would increase tongue strength. Method A prospective, case series intervention study was used. Six healthy women aged 53-78 years completed a 6-week mental practice tongue resistance exercise program utilizing motor imagery to imagine completion of tongue exercises. The main outcome was mean isometric maximum tongue pressures (tongue strength), which were collected at baseline and Weeks 2, 4, and 6 using the Iowa Oral Performance Instrument ( IOPI Medical, 2013 ). Results By Week 6 of the study, all participants had significantly increased their tongue strength compared to baseline. Conclusions The findings indicate that mental practice using motor imagery for tongue exercise may improve tongue strength in healthy individuals at risk for dysphagia and may thus represent a promising direction warranting further investigation in typically aging individuals and patients with dysphagia and decreased tongue strength.

The impact of time after radiation treatment on dysphagia in patients with head and neck cancer enrolled in a swallowing therapy program.

BACKGROUND: Swallowing dysfunction after radiotherapy (RT) for head and neck cancer can be devastating. A randomized control trial compared swallow exercises versus exercise plus neuromuscular electrical stimulation therapy and found no overall difference in outcomes. METHODS: Quality of life (QOL), diet, and swallowing variables collected at discrete intervals on 117 patients were reanalyzed to test the hypothesis that shorter time between the completion of radiotherapy and beginning of the swallowing therapy program yielded improved outcomes. RESULTS: At baseline, subjects < 1 year post radiation had significantly better function than subjects >2 years post RT in several measures. Over the therapy program, the early group showed significant improvement in diet and QOL. Swallowing physiologic variables showed no difference between groups. CONCLUSION: Beginning a swallowing therapy program within 1 year of completion of radiotherapy demonstrates more consistent improvement in QOL and diet performance compared to later periods.

A scoping review of rehabilitation interventions for survivors of head and neck cancer.

Purpose: The objectives of this scoping review were to summarize, understand, and disseminate findings from a broad body of literature on rehabilitation interventions used with survivors of head and neck cancer. Method: Searches were conducted in six databases. Inclusion criteria were studies of adult head and neck cancer survivors with a predefined primary rehabilitation outcome as a result of an intervention. Excluded were studies not written in English, opinion papers, or studies where the intervention was not carried out by a rehabilitation healthcare service. A second level, full-text review of the studies was conducted. A thematic analysis was used to examine and combine study findings. Results: A total of 3804 results were retrieved from all sources resulting in 39 papers that were analyzed. The thematic analysis of the included papers represented interventions focusing on swallowing and nutrition, speech, physical therapy, assistive devices, complementary and alternative modalities, comprehensive interdisciplinary programs, and preventive rehabilitation programs. Conclusion: This review has provided an overview of the scope of rehabilitation interventions available for survivors of head and neck cancer and preliminary information about their efficacy. This is foundational information for the development and refinement of rehabilitation interventions and programs for head and neck cancer survivors. Implications for Rehabilitation The existing evidence suggests that survivors of head and neck cancer can benefit from early screening of potential rehabilitation needs and being involved in preventive rehabilitation programs pre-surgery when possible. Rehabilitation programs should consider swallowing interventions for patients as evidence reports improved swallowing function, decreased pain and discomfort, and reduced duration of feeding tube use. Rehabilitation programs should consider nutritional interventions after radiotherapy: Patients benefited from stabilized weights, improved nutritional status, and an improved quality of life. Physical exercise interventions demonstrated improvements in physical function, muscular endurance, range of motion, overall quality of life, and showed reductions in pain, and fatigue.

Lip closure training improves eating behaviors and prefrontal cortical hemodynamic activity and decreases daytime sleep in elderly persons.

Previous research suggests that aging-related deterioration of oral functions causes not only eating/swallowing disorders but also various conditions such as sleep disorders and higher-order brain dysfunction. The aim of the present study was to examine the effects of lip closure training on eating behavior, sleep, and brain function in elderly persons residing in an elder care facility. The 20 elderly subjects (mean age, 86.3 ± 1.0 years) were assigned to a control group or a lip closure training (LCT) group, in which an oral rehabilitation device was used for daily LCT sessions over a 4-week period. Before and after the 4-week intervention period, maximal lip closure force was measured, and prefrontal cortical hemodynamic activity (changes in oxygenated hemoglobin concentration) during lip closure movements was measured with (LCT group) or without (control group) use of the oral rehabilitation device. We also analyzed eating behavior and daytime sleep before and after the intervention period. Compared with the control group, the LCT group showed improved maximal lip closure force, shortened eating time, decreased food spill rates, and decreased daytime sleeping. Furthermore, compared with the control group, the LCT group showed a significant increase in prefrontal cortical activity during lip closure. In addition, the increase rate in the right dorsolateral prefrontal cortical activity after the intervention period was significantly correlated with the increase rate in the maximal lip closure force after the intervention period. These findings suggest that LCT is useful in elderly individuals with decreased eating/oral and cognitive functions without the risk of pulmonary aspiration during training.

Utilizing Cerebral Perfusion Scan and Diffusion-tensor MR Imaging to Evaluate the Effect of Hyperbaric Oxygen Therapy in Carbon Monoxide-induced Delayed Neuropsychiatric Seqeulae- A Case Report and Literature Review.

PURPOSE: Detection of regional cerebral blood flow (rCBF) and/or brain magnetic resonance imaging (MRI) has been used to investigate functional defect of brain caused by carbon monoxide (CO) poisoning. In this report, we attempted to demonstrate the correlation of changes in brain singlephoton emission computed tomography (SPECT) and diffusion-tensor MR image (DTI) with functional improvement of severe delayed neuropsychiatric sequelae (DNS) after CO intoxication during the treatment of hyperbaric oxygen therapy (HBOT). CASE REPORT: The patient had normal activities of daily life after he recovered from acute CO poisoning. One month later, he presented symptoms of declined cognitive functioning, aphasia, apraxia, dysphagia, muscle rigidity, urine and fecal incontinence. After one course of HBOT, these symptoms improved significantly and the patient could regain most of his previous functioning. The patient's improvement was evidenced by increased rCBF in Brodmann areas 7, 8, 11 and 40, as well as higher mean fractional anisotropy (FA) value of DTI. CONCLUSION: Although the efficacy of HBOT in DNS patients is still needed to be evaluated in large clinical study, these data suggest that HBOT may be the choice to improve DNS efficiently and shorten the duration of suffering with favorable outcome.

NR2B subunit of the NMDA glutamate receptor regulates appetite in the parabrachial nucleus.

Diphtheria toxin-mediated, acute ablation of hypothalamic neurons expressing agouti-related protein (AgRP) in adult mice leads to anorexia and starvation within 7 d that is caused by hyperactivity of neurons within the parabrachial nucleus (PBN). Because NMDA glutamate receptors are involved in various synaptic plasticity-based behavioral modifications, we hypothesized that modulation of the NR2A and NR2B subunits of the NMDA receptor in PBN neurons could contribute to the anorexia phenotype. We observed by Western blot analyses that ablation of AgRP neurons results in enhanced expression of NR2B along with a modest suppression of NR2A. Interestingly, systemic administration of LiCl in a critical time window before AgRP neuron ablation abolished the anorectic response. LiCl treatment suppressed NR2B levels in the PBN and ameliorated the local Fos induction that is associated with anorexia. This protective role of LiCl on feeding was blunted in vagotomized mice. Chronic infusion of RO25-6981, a selective NR2B inhibitor, into the PBN recapitulated the role of LiCl in maintaining feeding after AgRP neuron ablation. We suggest that the accumulation of NR2B subunits in the PBN contributes to aphagia in response to AgRP neuron ablation and may be involved in other forms of anorexia.

Risk model and nomogram for dysphagia and xerostomia prediction in head and neck cancer patients treated by radiotherapy and/or chemotherapy.

In our randomized trial on hyperbaric oxygen (HBO), it was shown that HBO could reduce dysphagia and xerostomia, which are frequently encountered after (chemo-) radiotherapy (RT) and/or surgery for head and neck cancer (HNC). A risk model and nomogram are developed to select those patients who most likely will respond to HBO treatment. A total of 434 HNC patients treated from 2000 to 2008 were analyzed and filled out the EORTC QLQC-30 and H&N35 questionnaires. Age, gender, chemotherapy, T and N stages, site, radiotherapy technique, RT boost, surgery of the primary tumor and neck, bilateral RT, and dose were analyzed in a statistical model. The discriminative value of the model was evaluated based on receiver operating characteristics (ROC), the area under the curve (AUC), sensitivity, specificity, and proportion of correctly classified measures. Significant factors in predicting swallowing problems are age, follow-up duration, tumor site, chemotherapy, surgery of the primary tumor and neck, and dose. For dry mouth, the significant factors are age, gender, tumor site, N stage, chemotherapy, and bilateral irradiation. For dysphagia and xerostomia, the area under the ROC curve is 0.7034 and 0.7224, respectively, with a specificity of 89/77%, sensitivity of 27/58%, and a positive predictive value of 83/67% for dysphagia and xerostomia, respectively. The developed predictive risk model could be used to select patients for costly hyperbaric oxygen treatment to prevent or reduce severe late side effects of HNC treatment. Our model serves as a guideline for the Department of Radiation Oncology to reduce costs by excluding patients not amenable to hyperbaric oxygen protocols. The nomogram presented is a useful tool for clinicians in assessing patient risks when deciding on follow-up strategies (e.g., hyperbaric oxygen treatment) after RT or surgery for HNC.

Evaluation of the efficacy of two mouthrinses formulated for the relief of xerostomia of diverse origin in adult subjects.

OBJECTIVE: To evaluate the efficacy of two new mouthrinses in the reduction of xerostomía-associated symptomatology. BACKGROUND: Xerostomia is a common chronic health condition that affects a great number of adults and significantly deteriorates quality of life, such that treatment is necessary. MATERIALS AND METHODS: Sixty-seven adult subjects of both sexes presenting xerostomia of diverse origin were selected. Mouthrinses were tested using a double-blind, randomized, cross-over clinical trial with an intervining wash out period. RESULTS: The 100% of subjects presented sensation of dry mouth, and 86% stated sensation of thick saliva. Burning tongue sensation, need to drink liquids to swallow and the sensation of swallowing difficulty were recorded in more than 50% of the patients. The most frequent pathologies in the sample were depression, arthritis, and arterial hypertension. Results of the clinical tests showed that mouthrinse 1 relieves sensation of dry mouth, need to drink liquids, and swallowing difficulty. In contrast, mouthrinse 2 relieves only latter two symptoms. Both rinses were more effective in relieving xerostomía-associated symptomatology in patients taking 3 or more medicines simultaneously. CONCLUSION: Both mouthrinses were effective in relieving various xerostomia symptoms, could be distributed at a low cost, thereby improving the quality of life of population affected.

"Pharyngocise": randomized controlled trial of preventative exercises to maintain muscle structure and swallowing function during head-and-neck chemoradiotherapy.

PURPOSE: Dysphagia after chemoradiotherapy is common. The present randomized clinical trial studied the effectiveness of preventative behavioral intervention for dysphagia compared with the "usual care." METHODS AND MATERIALS: A total of 58 head-and-neck cancer patients treated with chemoradiotherapy were randomly assigned to usual care, sham swallowing intervention, or active swallowing exercises (pharyngocise). The intervention arms were treated daily during chemoradiotherapy. The primary outcome measure was muscle size and composition (determined by T(2)-weighted magnetic resonance imaging). The secondary outcomes included functional swallowing ability, dietary intake, chemosensory function, salivation, nutritional status, and the occurrence of dysphagia-related complications. RESULTS: The swallowing musculature (genioglossus, hyoglossuss, and mylohyoid) demonstrated less structural deterioration in the active treatment arm. The functional swallowing, mouth opening, chemosensory acuity, and salivation rate deteriorated less in the pharyngocise group. CONCLUSION: Patients completing a program of swallowing exercises during cancer treatment demonstrated superior muscle maintenance and functional swallowing ability.

A prospective, randomized trial of nerve monitoring of the external branch of the superior laryngeal nerve during thyroidectomy under local/regional anesthesia and IV sedation.

BACKGROUND: The aim of this study was to assess the impact of the neuromonitoring of the external branch of the superior laryngeal nerve (EBSLN) on the voice quality after mini-incision thyroidectomy under local/regional anesthesia and intravenous sedation. METHODS: Patients undergoing mini-incision thyroidectomy under local anesthesia were prospectively randomized for either nerve monitoring of the EBSLN (group 1) or no nerve monitoring (group 2). Voice and swallowing assessment were obtained by using the Voice Handicap Index-10 (VHI-10) and the Reflux Symptom Index questionnaires (RSI) before surgery and at 3 weeks and 3 months after surgery. RESULTS: Recruitment led to 22 patients in group 1 and 25 patients in group 2. The rate of visualized EBSLN was higher in group 1 (66% vs 21%; P = .003). Contrary to group 1, in group 2, the median total VHI-10 score was significantly higher 3 months after surgery (P = .034) compared with preoperatively, indicating a subjective voice handicap. In both groups, there was no difference in median total RSI score before surgery or at 3 weeks and 3 months after surgery. CONCLUSION: Nerve monitoring aids in the visualization of the EBSLN during mini-incision thyroidectomy under local/regional anesthesia and leads to an improvement in patient-assessed voice quality after surgery but does not impact swallowing.

Early hyperbaric oxygen therapy for reducing radiotherapy side effects: early results of a randomized trial in oropharyngeal and nasopharyngeal cancer.

PURPOSE: Comparison of quality of life (QoL) and side effects in a randomized trial for early hyperbaric oxygen therapy (HBOT) after radiotherapy (RT). METHODS AND MATERIALS: From 2006, 19 patients with tumor originating from the tonsillar fossa and/or soft palate (15), base of tongue (1), and nasopharynx (3) were randomized to receive HBOT or not. HBOT consisted of 30 sessions at 2.5 ATA (15 msw) with oxygen breathing for 90 min daily, 5 days per week, applied shortly after the RT treatment was completed. As of 2005, all patients received validated questionnaires (i.e., the European Organization for Research and Treatment of Cancer [EORTC] QLQ-C30, EORTC QLQ Head and Neck Cancer Module (H&N35), Performance Status Scale): before treatment; at the start of RT treatment; after 46 Gy; at the end of RT treatment; and 2, 4, and 6 weeks and 3, 6, 12, and 18 months after follow-up. RESULTS: On all QoL items, better scores were obtained in patients treated with hyperbaric oxygen. The difference between HBOT vs. non-HBOT was significant for all parameters: EORTC H&N35 Swallowing (p = 0.011), EORTC H&N35 Dry Mouth (p = 0.009), EORTC H&N35, Sticky Saliva (p = 0.01), PSS Eating in Public (p = 0.027), and Pain in Mouth (visual analogue scale; p < 0.0001). CONCLUSIONS: Patients randomized for receiving hyperbaric oxygen after the RT had better QoL scores for swallowing, sticky saliva, xerostomia, and pain in mouth.

Acupuncture as an optional treatment for hospice patients with xerostomia: an intervention study.

More than 70% of seriously ill patients with cancer suffer from xerostomia and the associated problems of swallowing, chewing and speaking. This study aims to investigate whether treatment with acupuncture is a viable option for hospice patients with xerostomia. During a 2-year period, 117 patients were assessed for xerostomia. Eighty-two patients were found to have moderate xerostomia. Sixty-seven fulfilled the criteria for inclusion. Of these, 14 were included but only eight completed the study. Ten acupuncture treatments were given during a 5-week period. The effect of acupuncture was measured using a visual analogue scale, and by measuring the saliva production before and after the series of treatment. The results show that all the patients experienced alleviation of dryness of the mouth and the associated symptoms, and thus benefited from the acupuncture treatment. However, conducting a 5-week acupuncture intervention study is not feasible at an inpatient hospice due to the patients being too close to death.

Masticatory dysfunction in persons with Down's syndrome. Part 2: management.

The functional and anatomical characteristics of Down's syndrome have direct repercussions on oral health; orofacial dysfunction results and feeding and swallowing are impaired. These problems have been described in an earlier article. Different techniques are proposed for the prevention of the development of orofacial dysfunction in Down's syndrome. In particular, early myofunctional therapy coupled with appliance wear has been shown to be successful over the long term when multidisciplinary management is possible. Functional or conventional orthodontic treatment may be successful for older children when performed concurrently with the use of appropriate behaviour management techniques. More recently, techniques for the compensation of masticatory dysfunction in adults have been proposed, although further research is necessary to confirm their efficacy. The aim of this second article was to review techniques for the prevention, treatment and compensation of orofacial dysfunction in persons with Down's syndrome from birth to adulthood.
