Orofacial function and monitoring of oral care in amyotrophic lateral sclerosis

Physical therapy for muscle strengthening in individuals with amyotrophic lateral sclerosis: A protocol for a systematic review and meta-analysis

INTRODUCTION

People with Amyotrophic Lateral Sclerosis (ALS) can present initially muscle weakness, which is a debilitating symptom that may be improved by engaging in muscle strengthening activities. Currently, the effects of motor interventions for muscle strengthening in people with ALS are unclear. This review intends to analyze the effects of motor interventions for muscle strengthening in individuals with ALS.

METHODS AND ANALYSIS

Randomized, non-randomized, and quasi-experimental clinical trials assessing individuals with ALS of both sexes, aged 18 years or older, who have received motor interventions for muscle strengthening considering all practices that can lead to increased strength, endurance, power and muscular hypertrophy will be included. No restriction on language, location, or publication date will be applied. MEDLINE, EMBASE, Cochrane Library (CENTRAL), SPORTDiscus, and Physiotherapy Evidence Database (PEDro) databases will be searched. The US National Institutes of Health Ongoing, ClinicalTrials.gov, and the reference lists of included studies will also be searched. Two reviewers will independently screen titles and abstracts and extract data from included studies. The methodological quality of the included studies will be assessed by the PEDro scale and the certainty of the evidence by the GRADE approach. Disagreements will be resolved by a third researcher. Findings will be presented in text and table formats. A meta-analysis will compare the effects of motor interventions for muscle strengthening versus placebo or other interventions.

Dental Management of Patients With Amyotrophic Lateral Sclerosis

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that affects the upper and lower motor neurons with upper and lower motor neuron manifestations. It is divided into two variants: a spinal onset and a bulbar onset. The first starts as focal muscle weakness and wasting that spreads with disease progression, while the second phenotype presents with dysarthria, dysphonia, and dysphagia. Moreover, an extra-motor manifestation could be reported with the most commonly reported symptoms being the change in cognition and sleep disorder. Oral manifestations include increased salivation, limited mouth opening, and dysphagia. Patients with ALS have difficulty maintaining oral hygiene, and it is important for the practitioner and the caregiver to take care of this group of population. We herein provide a short review of the disease with a focus on the oral manifestations and dental considerations for management for this group.

Evaluation of orofacial dysfunctions and oral health-related quality of life in children with asthma

Objective: This study aimed to investigate the impact of asthma on oro-facial muscle dysfunction (OFD) and oral health-related quality of life (OHRQoL) in children. Materials and Method: A total of 158 children, 79 diagnosed with asthma and 79 healthy, were included in the study. Children diagnosed with asthma were divided into controlled and uncontrolled asthma groups. The OFD and OHRQoL of all participants were evaluated with Nordic Orofacial Test and Screening (NOT-S) and Child Perception Questionnaire (CPQ8-10). The differences and correlations between the groups were statistically evaluated (Mann-Whitney and Spearman and Chi-Square test). Results: NOT-S interview, examination, and total scores were statistically higher in the asthma group compared to healthy children and between uncontrolled and controlled asthma groups (p<0.001). Higher scores were obtained in all areas of CPQ8-10 in the asthma group (p<0.001). NOT-S and CPQ8-10 scores elevated compatibly in the groups diagnosed with asthma. Conclusion: OFD in asthmatic children predicts worse OHRQoL.

Prevalence of Sialorrhea Among Amyotrophic Lateral Sclerosis Patients: A Systematic Review and Meta-Analysis

BACKGROUND AND OBJECTIVES

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative motor neuron disease (MND), and sialorrhea is a known symptom in patients with ALS, which may cause a social embarrassment and discomfort. However, people do not pay attention to sialorrhea up to now. This study is aimed at conducting a systematic review and meta-analysis of the pooled prevalence of sialorrhea in ALS patients all around the world and raising awareness of salivation.

METHODS

We searched PubMed and EMBASE databases to obtain the comprehensive literatures which reported the prevalence of sialorrhea. We used AHRQ and NOS to evaluate the literature quality. Subgroup analyses were performed based on screening instruments and severity of sialorrhea. At the meantime, sensitivity analyses was also conducted to identify the source of heterogeneity.

RESULTS

A total of 17 eligible studies which included 21 groups of data reported prevalence of sialorrhea. The pooled prevalence of sialorrhea among ALS patients was 30.8% (95% CI: 20.0%-44.2%). For studies using ALSFRS-R, direct questioning, postal survey, and ALSSoL average and ALSFRS-R, the pooled prevalence of sialorrhea was 22.7%, 25.8%, 29.8% and 52.0% respectively. According to the severity of sialorrhea, the prevalence of mild, moderate, and severe sialorrhea were 25.1%, 11.2%, and 10.5%, respectively. And none of the studies alone had a significant effect on the overall prevalence of sialorrhea after we eliminated each study separately in sensitivity analyses.

CONCLUSIONS

Sialorrhea is a relatively common symptom in ALS patients with a comparatively high prevalence. In our study, we found that the prevalence of sialorrhea in ALS patients is relatively higher than the results based on direct questioning or postal survey. Therefore, we deduced that sialorrhea should be evaluated by more complex professional assessment scales to improve the quality of life and improve early prognosis of disease.

What can a dentist learn from an astrophysicist? A photographic evaluation of the long-term impact of amyotrophic lateral sclerosis on the orofacial sphere, using the example of Stephen Hawking: A historical case report

Aims

The present historical case report aims to characterize the long‐term orofacial repercussions of amyotrophic lateral sclerosis (ALS), a rare neurodegenerative disease with poor prognosis and relatively short life expectancy following initial diagnosis.

Methods

Here we focus on the long‐term orofacial evolution seen in the example of Stephen Hawking, one of the greatest personalities in the scientific world, using publicly‐available photographic documentation. The fact that Stephen Hawking lived several decades following his diagnosis of ALS presents one with a unique opportunity to characterize and follow‐up the evolution of the ALS on the orofacial sphere. Through this article, we want to show him and his family, and all those living with this disease, our deepest respect, without intending in any way to intrude or misuse the privacy of the late universally‐respected astrophysicist.

Results

Photographic documentation analyzed longitudinally shows changes towards the development of a Class III malocclusion, lower incisor protrusion, and a concave profile. Moreover, tooth wear has occurred, accompanied by posterior tooth loss and aberrant tongue and lip posture.

Conclusion

The causes of such changes remain speculative but could be due to changes in the soft tissue equilibrium, changes in head and tongue posture, loss of oral function, respiratory needs, and a general deterioration of dental health. Our sincere thanks to the Hawking family who took the time to read the article and approve its publication for scientific and educational purposes. We are also deeply grateful to them for providing us with some photographs from their family collection.

Oral hygiene in patients with motor neuron disease requires attention: A cross-sectional survey study

Aims

Motor Neuron Disease (MND) is a progressive neurodegenerative neuromuscular disease, which can progressively impair arm‐hand function. Needs and barriers of MND patients and their caregivers in performing oral hygiene were studied.

Methods

An online survey was sent to 706 MND patients. The questions of the survey included self‐reliance, self‐reported oral health, and oral hygiene. The oral health‐related quality of life (GOHAI‐NL) and the subjective well‐being (ALSAQ‐5) were also measured.

Results

A total of 259 patients responded (36.7%), of which 71.9% stated not to be informed about the importance of maintaining good oral health by their MND treatment team. Moreover, 40.4% would like to receive help concerning oral hygiene from a dental professional. 19.8% were not satisfied about oral care as conducted by themselves or their caregivers. Patients who do not ask for support with their daily oral care had a significantly worse oral health‐related quality of life compared to patients who do ask for support.

Conclusions

The support for daily oral hygiene of MND patients and their barriers to requesting support needs more attention from both MND‐treatment teams and general dental professionals.

Oral function in amyotrophic lateral sclerosis patients: A matched case-control study

BACKGROUND & AIMS

Patients with amyotrophic lateral sclerosis (ALS) develop swallowing difficulties with the progression of the disease. The present study aimed at comparing oral function and body composition between ALS patients and healthy controls, and at evaluating which parameters are the most discriminant between both groups.

METHODS

We included ALS patients at the start of their multidisciplinary follow-up at the Geneva University Hospitals and healthy age-, gender-, and dental status-matched adults. We assessed the severity of the disease through the ALS Functional Rating Scale and the swallowing difficulties through the EAT-10 score. We performed an intraoral examination of the dental status, and measured chewing performance, bite, lip and tongue force, saliva weight, and body composition. Group comparisons were performed with t-tests or Mann-Whitney tests as appropriate. Linear discriminant analysis was used to determine the most discriminant parameters between groups.

RESULTS

Twenty-six ALS patients (bulbar onset: n = 7, median (IQR) ALS Functional Rating Scale: 37 (11)) were included. The ALS patients had a significantly lower chewing performance (p < 0.001), lip force (p < 0.001), tongue force (p = 0.002), saliva weight (p < 0.004) and fat-free mass index (p < 0.001) as compared to the healthy individuals, and a higher EAT-10 score (p < 0.001). In ALS patients, a low chewing performance was correlated with a low bite (r = -0.45, p < 0.05)) and tongue force (r = -0.59, p < 0.05). The most discriminant parameters between both groups, by order of importance, were chewing performance, fat-free mass index and saliva weight and allowed the calculation of a discriminant function.

CONCLUSION

Compared to healthy controls, ALS patients have significant alterations of oral function and body composition. The most discriminant parameters between both groups were chewing performance, fat-free mass index and saliva volume. It remains to be demonstrated whether oral parameters predict outcome.

Relationship between Oral Hypofunction and Sarcopenia in Community-Dwelling Older Adults: The Otassha Study

Oral hypofunction, resulting from a combined decrease in multiple oral functions, may affect systemic-condition deterioration; however, few studies have examined the association between oral hypofunction and general health among older adults. In this cross-sectional study, we examined the relationship between oral hypofunction and sarcopenia in community-dwelling older adults. We included 878 adults (268 men and 610 women, mean age 76.5 ± 8.3 years). Tongue coating index, oral moisture, occlusal force, oral diadochokinesis (/pa/,/ta/,/ka/), tongue pressure, mas-ticatory function, and swallowing function were evaluated as indicators of oral hypofunction. Grip strength, gait speed, and skeletal muscle mass index were measured as diagnostic sarcopenia parameters. The association between oral hypofunction and sarcopenia was examined via logistic regression using sarcopenia as the dependent variable. Oral hypofunction prevalence was 50.5% overall, 40.3% in men, and 54.9% in women. The prevalence of sarcopenia was 18.6% overall, 9.7% in men, and 22.5% in women. A logistic regression showed oral hypofunction, age, body mass index, higher-level functional capacity, and serum albumin level were significantly associated with sarcopenia. Sarcopenia occurred at an increased frequency in patients diagnosed with oral hypofunction (odds ratio: 1.59, 95% confidence interval: 1.02–2.47); accordingly, oral hypofunction appears to be significantly associated with sarcopenia.

Functional status and oral health in patients with amyotrophic lateral sclerosis: A cross-sectional study

BACKGROUND

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting upper and lower motor neurons. The current practice of caring for patients affected by ALS involves a multidisciplinary team without any indication about oral health care.

OBJECTIVE

We sought to investigate the functional status and oral health in patients with ALS to define a specific multidisciplinary management.

METHODS

In this cross-sectional study, we included patients affected by ALS, evaluating their functional status, using the Revised ALS Functional Rating Scale (ALSFRS-R) and their oral health status through specific parameters, including Brief Oral Health Status Examination (BOHSE), Winkel Tongue Coating Index (WTCI), and Oral Food Debris Index (OFDI).

RESULTS

All 37 patients (mean age: 61.19±11.56 years) showed a poor oral status, independent from the functional status and strictly correlated to the severity of sialorrhea (p = 0.01). OFDI index was negatively correlated with the ALSFRS-R upper limb (p = 0.03). Patients with bulbar onset had significantly lower ability to perform adequate tongue movements in terms of protrusion (p = 0.006) and lateralization (p < 0.001). Significant negative correlations between survival rate and BOHSE (p = 0.03) was found.

CONCLUSIONS

Taken together, our findings showed that a poor oral health status might be correlated to a worse functional status and survival time. Thus, an adequate oral health care and rehabilitation should be considered as crucial in the multidisciplinary management of patients with ALS.

A Novel Method for Triggering the Swallowing Reflex in Patients with Amyotrophic Lateral Sclerosis: the Ishizaki Press Method

This study describes the identification of specific maxillofacial points triggering the swallowing reflex by finger pressure in a patient with severe amyotrophic lateral sclerosis. This method has been named as the "Ishizaki Press Method." The first point was identified in a serendipitous encounter during training sessions to aid communication. This led to the search for such additional points, after obtaining informed consent from the patient and his relatives. Seven effective points were identified: the depressions in front of the left and right tragus (Ting gong points), bilateral points over the parotid and submandibular glands, and a point over the mentum in the midline of the face. The efficacy of these trigger points was noted to be ≥ 70%. The mean time taken for swallowing to occur in response to the stimulation at each of these points was less than 10 s, and the induction of a rapid swallowing reflex was recognized. Alternating left and right stimulations of the Ting gong points and the parotid points triggered the swallowing reflex significantly faster than unilateral stimulations alone. The Ishizaki Press Method may improve the management of dysphagia in patients with amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis and intestinal microbiota-toward establishing cause and effect

The intestinal microbiota may be involved, through metabolic gut-brain interactions, in a variety of neurological conditions. In this addendum, we summarize the findings of our recent study investigating the potentially modulatory influence of the microbiome in a transgenic ALS mouse model, and the possible application to human disease. We found that transgenic mice show evidence of dysbiosis, even at the pre-symptomatic stage, and have a more severe disease course under germ-free conditions or after receiving broad-spectrum antibiotics. We demonstrated that Akkermansia muciniphila ameliorated the disease in mice and that this may be due to the production of nicotinamide. We then conducted a preliminary study in human ALS and identified functionally similar alterations within the metagenome. Furthermore, we found that patients with ALS had lower systemic and CSF levels of nicotinamide, suggesting that the changes observed in the mouse model may be relevant to human disease.

Assessment of orofacial dysfunction using the NOT-S method in a group of Turkish children with cerebral palsy

OBJECTIVES

A healthy determination of orofacial findings of children with cerebral palsy is important as this will lead us to utilize perfect multidisciplinary therapies of orofacial dysfunctions (OFD). Nordic Orofacial Test-Screening (NOT-S) is a comprehensive screening method of OFD which consists of a structured interview and clinical examination. The aim of our study was to evaluate the orofacial dysfunctions in a group of Turkish children with cerebral palsy using Nordic Orofacial Test-Screening (NOT-S) and find out the factors associated with OFD comparatively with a healthy group.

MATERIALS AND METHODS

NOT-S was applied to 84 children aged 3-16 years. Forty-two children with cerebral palsy were included in the study group and 42 healthy children were randomly selected for the control group. Two trained and calibrated examiners who were experienced on NOT-S interview and examination of the validity and reliability of the Turkish version performed screening and interpreted the results.

RESULTS

NOT-S interview and clinical examination subscale scores of children with cerebral palsy were higher and found to be statistically significant (Mann-Whitney U test; p < 0.001). The total scale score of the cerebral palsy group was also statistically significant (p < 0.001). The most common dysfunctions were in the facial expression area (55.9%) and in the chewing and swallowing area (52.4%) following in sensory function area (47.6%).

CONCLUSIONS

The results of this study indicated that the NOT-S protocol was an effective and valuable tool for the comprehensive screening of orofacial dysfunctions in a group of Turkish children with cerebral palsy.

Oral health status of hospitalized amyotrophic lateral sclerosis patients: a single-centre observational study

OBJECTIVE

To assess the intraoral conditions and oral function of patients with amyotrophic lateral sclerosis (ALS).

MATERIAL AND METHODS

This single-centre, cross-sectional observational study included 50 ALS patients, who were treated with tracheostomy positive-pressure ventilation (TPPV) while hospitalized. The disease duration, TPPV duration, current number of teeth, number of occlusal units, number of decayed/missing/filled teeth, community periodontal index, bleeding on probing, dental calculus, maximum mouth opening, salivation rate, tongue anomalies (atrophy or hypertrophy) and tongue coating were determined for each patient. Differences in intraoral conditions according to disease duration or TPPV duration were statistically analysed.

RESULTS

The maximum mouth opening was low in the included patients, with a mean distance of 13.7 ± 7.4 mm. Furthermore, the maximum mouth opening showed a significant negative correlation with both disease duration and TPPV duration. No statistically significant differences were found between any other intraoral parameters and disease duration or TPPV duration.

CONCLUSIONS

Severe dental disease is uncommon among hospitalized ALS patients who receive oral care by nurses; however, mouth opening is very restricted in these patients. Early intervention for restricted mouth opening, directed by a dentist or dental hygienist, is essential in this population.

Functional limitation of the masticatory system in patients with bulbar involvement in amyotrophic lateral sclerosis

Amyotrophic lateral sclerosis (ALS) with bulbar dysfunction affects the motor neurons responsible for controlling the muscles in the jaw, face, soft palate, pharynx, larynx and tongue. This cross-sectional study aimed to determine the functional limitation of the jaw in patients with ALS and bulbar dysfunction who had upper motor neuron (UMN), lower motor neuron (LMN) or balanced involvement. One hundred and fifty-three patients with ALS and 23 controls were included. All participants answered using the 8-item Jaw Functional Limitation Scale (JFLS-8). Patients with ALS were grouped by neurologic examination as follows: non-bulbar ALS, bulbar UMN-predominant ALS; bulbar LMN-predominant ALS; and bulbar balanced (UMN + LMN) ALS. Jaw limitation between the different groups was compared using the Kruskal-Wallis test. Patients with non-bulbar ALS had similar mandibular limitations to healthy participants. Only patients with balanced UMN and LMN bulbar manifestations reported greater difficulties in chewing soft food or in jaw mobility compared to the non-bulbar ALS group. Patients with bulbar involvement also had greater difficulties in chewing tough food or chicken and in swallowing and talking compared to the non-bulbar group, regardless of whether UMN or LMN predominant. No significant differences were found between the groups in smiling and yawning difficulties. Bulbar involvement in patients with ALS is associated with functional limitation of the masticatory system. However, balanced bulbar UMN and LMN involvement is associated with the worst impairments in chewing soft food and in opening the jaw widely.
