[PMID: 37898423 DOI: 10.1016/j.jpeds.2023.113803] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Revised: 10/05/2023] [Accepted: 10/23/2023] [Indexed: 10/30/2023]
Abstract
OBJECTIVE To compare efficacy and side effect profile data on conservative, behavioral, pharmacological, and surgical treatments used for pediatric saliva control. STUDY DESIGN A cohort study of children (n = 483) referred to a specialty Saliva Control service between May 2014 and November 2019 was performed, using quantitative data from pretreatment and post-treatment questionnaires (the Drooling Impact Scale [DIS], Drooling Rating Scale [DRS]) and recording of side effects. Overall, 483 children were included; treatment choices were based on published international guidelines. RESULTS The greatest improvement was seen after intraglandular botulinum toxin A (BTX-A) injections (n = 207; 551 courses; mean DIS change, 34.7; 95% CI = 29.2-35.7) or duct transpositional surgery (n = 31; mean change in DIS, 29.0; 95% CI, 22.3-35.7). Oral anticholinergics were associated with good outcomes, with no significant statistical difference between glycopyrronium bromide (n = 150; mean DIS change, 21.5; 95% CI, 19.1-24.0) or trihexyphenidyl (n = 87; mean DIS change, 22.4; 95% CI, 18.9-25.8). Inhaled ipratropium bromide was not as efficacious (n = 80; mean DIS change, 11.1; 95% CI, 8.9-13.3). Oromotor programs were used in a selected group with reliable outcomes (n = 9; mean DIS change, 13.0). Side effects were consistent with previous studies. Overall, in cases of milder severity, enterally administered therapies provided a good first-line option. With more severe problems, BTX-A injections or saliva duct transpositional surgery were more effective and well tolerated. CONCLUSIONS We describe a large, single-center pediatric saliva control cohort, providing direct comparison of the efficacy and side effect profiles for all available interventions and inform clinical practice for specialists when considering different options. BTX-A injections or saliva duct transpositional surgery seem to be more effective for saliva control that is more severe.

Evaluation of an intensive voice treatment to reduce anterior drooling in children with cerebral palsy: Protocol for a concurrent multiple-baseline, single case experimental design study. Contemp Clin Trials Commun 2021; 24:100872. [PMID: 34825105 PMCID: PMC8605272 DOI: 10.1016/j.conctc.2021.100872] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Revised: 09/29/2021] [Accepted: 11/13/2021] [Indexed: 12/04/2022] Open
Abstract
Anterior drooling is common in children with cerebral palsy (CP) and poses significant risks to the child's health. Causes of drooling include oro-motor dysfunction, inefficient swallowing and reduced sensation in the orofacial musculature. Behavioural interventions are frequently recommended to reduce drooling; however, this is in the absence of high-quality research evidence. This paper describes a protocol for evaluating the effectiveness of the Lee Silverman Voice Treatment LOUD (LSVT LOUD®) in reducing drooling; and optimising speech and swallowing in a group of children with CP. A structured and systematic visual analysis supplemented with statistical analyses will be used to analyse the data. The risk of bias in n-of-1 trials (RoBiNT) Scale [1] guided the design and implementation of the study.

Abstract
BACKGROUND Drooling is common in children with neurological disorders, but its management is very challenging, Scopolamine transdermal patch (STP) appears to be useful in controlling drooling, although it is not approved for this indication and there are limited clinical studies about its effectiveness. This study aimed (1) to assess the impact of STP use on the severity of drooling and on the frequency of emergency department (ED) and hospital readmission (RA) visits related to drooling, and (2) to determine the level of family satisfaction with STP when used in children with neurological disorders. METHODS This is a retrospective cohort study of all pediatric patients aged 3-14 years, with non-progressive neurodevelopmental disability, who used STP for more than one year during the period between April 2015 and July 2018 (n = 44). Data on demographics, clinical status, comorbidities, STP dose and duration, other medications, ED and RA visits were collected. Follow-up phone-call interviews with parents/caregivers were performed using a parent-reported frequency and severity rating scale of sialorrhea. Absolute and relative risk reductions were calculated to assess the impact of STP on ED and RA visits. Significance was considered at p-value of ≤ 0.05. RESULTS STP use showed significant reduction in severity of drooling (p < 0.001), wiping of the child's mouth (p < 0.001), bibs or clothing changes (p < 0.001), choking and aspiration of saliva (p = 0.001). The Relative Risk Reduction of the drooling-related ED and RA visits were 86% and 67% respectively. Nearly two-thirds (60%) of caregivers were satisfied with using STP. CONCLUSIONS This is the first study of its kind done in Saudi Arabia demonstrating favorable impact of STP use by children on the consequences associated with drooling and with the frequency of ER and RA visits due to drooling. Development of a medication use protocol is recommended to standardize STP treatment in order to optimize its effectiveness. This study serves as baseline information for future prospective interventional studies.

Abstract
AIM The aims of this study were to examine whether objective measurements of the 10-minute drooling quotient (DQ10) and the 5-minute drooling quotient (DQ5) are interchangeable; to assess agreement between the measurements and their accuracy in classifying drooling severity; and to develop a time-efficient clinical assessment. METHOD The study cohort included 162 children (61 females, 101 males; mean age 11 y 6 mo, SD 4 y 5 mo, range 3 y 9 mo-22 y 1 mo) suffering from moderate to profuse drooling. One hundred and twenty-four had cerebral palsy and 38 had other developmental disabilities. Seventy-four of the participants were ambulant and 88 non-ambulant. The original DQ10 was recalculated into a 5-minute score (DQ5). Assessments were undertaken while the participants were in a rest situation (DQ(R)) and while they were active (DQ(A)). Agreement in scores was quantified using intraclass correlations and Bland-Altman plots. To classify drooling, area under the receiver operating characteristic curve analysis was used to compare accuracy of the DQ10 and DQ5 at rest and during activity. RESULTS Agreement between DQ10A, and DQ5(A), and between DQ10(R) and DQ5(R) was high (intraclass correlation coefficient >0.90). Moderate agreement existed between DQ(A) and DQ(R). DQ(A) scores were more accurate in classifying children's drooling behaviour. For DQ5(A), a cut-off point of 18 or more (drooling episodes/observation time) might indicate 'constant drooling'. INTERPRETATION The DQ10 and DQ5 can be used interchangeably. DQ(A) is most discriminative for drooling severity. For evaluating treatment efficiency the cut-off point can be used. For clinical and research purposes, the DQ5 is time efficient and cost saving while validity, and intrarater and interrater reliability are preserved.

Abstract
AIM The aim of this paper was to systematically review the efficacy and safety of botulinum toxin (BoNT) injections to the salivary glands to treat drooling in children with cerebral palsy and neurodevelopmental disability. METHOD A systematic search of The Cochrane Central Register of Controlled Trials, PubMed, CINAHL (Cumulative Index to Nursing and Allied Health Literature), EMBASE, and the Physiotherapy Evidence Database (PEDro) was conducted (up to 1 October 2011). Data sources included published randomized controlled trials (RCTs) and prospective studies. RESULTS Sixteen studies met inclusion criteria. Three outcome measures support the effectiveness of BoNT for drooling. One RCT found an almost 30% reduction in the impact of drooling on patients' lives, as measured by the Drooling Impact Scale (mean difference -27.45; 95% confidence interval [CI] -35.28 to -19.62). There were sufficient data to pool results on one outcome measure, the Drooling Frequency and Severity Scale, which supports this result (mean difference -2.71; 95% CI -4.82 to -0.60; p<0.001). There was a significant reduction in the observed number of bibs required per day. The incidence of adverse events ranged from 2 to 41%, but was inconsistently reported. One trial was terminated early because of adverse events. INTERPRETATION BoNT is an effective, temporary treatment for sialorrhoea in children with cerebral palsy. Benefits need to be weighed against the potential for serious adverse events. More studies are needed to address the safety of BoNT and to compare BoNT with other treatment options for drooling.

Abstract
Many individuals with neurological problems or anatomical abnormalities of the jaw, lips or oral cavity may drool, which can impact on health and quality of life. A thorough evaluation of the patient's history, examination of the oral region by a speech pathologist and, in individuals over 3 years, a dental examination is warranted. Questionnaires with established validity such as the Drooling Impact Scale are useful assessment tools. A hierarchical approach to treatment is taken from least invasive therapies, such as speech pathology, to more invasive, such as injection of botulinum neurotoxin type-A (BoNT-A) into the salivary glands (parotid and submandibular). The wishes of the individual and their carer are crucial considerations in determining the suitability of the intervention for the patient. In the presence of dysphagia and cerebral palsy (CP), careful assessment is required prior to the injection of BoNT-A. Favourable responses to intervention include a reduction in the secretion of saliva and in drooling, as well as psychosocial improvements. BoNT-A is usually well tolerated, although potential side effects should be discussed with the patient and carer.

Abstract
AIM To describe the development and clinimetric properties of a new scale to evaluate changes in the impact of drooling in children with developmental disabilities. METHOD After examining the properties of potential items, 10 items were retained for inclusion in the final Drooling Impact Scale. The clinimetric properties of the scale were evaluated using data from two convenience samples of children attending a saliva-control clinic: a stable group (n=31, 22 males, nine females; mean age 10y 7mo, SD 4y 5mo, range 3y 6mo-18y 3mo; cerebral palsy [CP] n=17, intellectual disability n=10; non-ambulatory n=13, nonverbal n=12) and an intervention group (n=49, 29 males, 20 females; mean age 11y, SD 3y 6mo, range 3y 4mo-16y 10mo; CP n=31, intellectual disability n=15; non-ambulatory n=27, nonverbal n=28). To assess validity, changes in scores on the Drooling Impact Scale over time were compared with a carer's global rating of change using Pearson's correlations and t-tests. A concordance correlation coefficient was used to compute the level of agreement between assessments 1 month apart in stable children. Effect size, standardized response mean, Guyatt responsiveness statistic, and an unpaired t-test were used to estimate responsiveness. RESULTS The correlation between the global rating and change in Drooling Impact Scale scores was 0.69 (p<0.001). The concordance correlation coefficient was 0.85. An effect size of 1.8, standardized response mean of 1.5, Guyatt responsiveness statistic of 1.4, and mean group difference of 23.5 (95% confidence interval 17.4-29.6) were obtained. INTERPRETATION The Drooling Impact Scale is a valid and reliable subjective measure that is responsive to change.

Abstract
OBJECTIVE To investigate the applicability of the swab method in the measurement of salivary flow rate in multiple-handicap drooling children. To quantify the measurement error of the procedure and the biologic variation in the population. STUDY DESIGN Cohort study. METHODS In a repeated measurements design, a baseline series of salivary flow rates were obtained from 45 children. The within-subject SD (SW) was calculated to express the measurements error according to a procedure introduced by Bland and Altman. RESULTS Two hundred twenty-four samples (mean 0.40 mL/min, SD 0.19 mL/min) were obtained and analyzed. The results of this study indicate that consistent scores were obtained at subsequent measurements, and good parity existed between the two measurements of salivary flow rate at each session. The SW could be estimated (0.11 mL/min), which was applied to quantify the specific variation of the salivary flow rate in our population. CONCLUSION According to Bland and Altman, the SW, which is a quantification of the measurement error and biologic variation, was found to be a useful tool to evaluate the obtained baseline salivary flow rate measurements. The swab method can be used to evaluate salivary flow rates in drooling children with cerebral palsy during interventional studies that aim to reduce saliva production.

Abstract
RATIONALE Clozapine is an atypical antipsychotic agent with proven efficacy in refractory schizophrenia, but its widespread use is limited by adverse effects such as agranulocytosis, seizures, sedation, weight gain, and sialorrhea. Clozapine-induced sialorrhea (CIS) is bothersome and has socially stigmatizing adverse effects, which result in poor treatment compliance. The pathophysiology of this condition is poorly understood and the treatment options available are based mostly on case reports and open-label studies. OBJECTIVE To review the available studies on CIS. METHOD All relevant studies available through PUBMED search supplemented with manual search were undertaken. RESULT The clinical features, complications, assessment, pathophysiology, and management of CIS are discussed. CONCLUSION Although the studies evaluating the therapeutic options has limitations and no drug has been found to be superior, judicious use of pharmacological agents along with behavioral methods will reduce this troublesome side effect and enhance compliance.

Abstract
Drooling of saliva appears to be the consequence of a dysfunction in the coordination of the swallowing mechanism, resulting in excess pooling of saliva in the anterior portion of the oral cavity and the unintentional loss of saliva from the mouth. Drooling can produce significant negative effects on physical health and quality of life, especially in patients with chronic neurological disabilities. Various approaches to manage this condition have been described in the literature, including oral motor therapy, behavior modification via biofeedback, orofacial regulation therapy, drug therapy, radiotherapy, and surgical treatments. Minimally invasive modalities, such as injection of botulinum toxin, photocoagulation, and acupuncture, have also been reported. This article provides a comprehensive and thorough overview of drooling, with an emphasis on understanding its etiologies and modalities of treatment.

Abstract
OBJECTIVES To share our experience in the management of drooling in Hong Kong, to describe the clinical profile of children with this problem, and to report the clinical outcome of oro-motor training. METHODS Children attending the Drooling Clinic of Alice Ho Miu Ling Nethersole Hospital, Hong Kong between January 2000 and June 2003 were included. Multidisciplinary assessment was performed to ascertain the medical condition, functional status and oro-motor difficulties of each child. Intervention might include optimization of medical condition, oro-motor training and surgery. Severity of drooling was rated by a 10-point visual analogue scale (VAS). The outcome of oro-motor training was assessed by the change in VAS from baseline. RESULTS Eight children, with a mean age of 11.9 years, were included. Six children suffered from cerebral palsy and two had syndromal diagnoses. All had moderate or severe mental retardation. Poor lip closure, inadequate jaw control and delay in swallowing were common oro-motor difficulties. All children received oro-motor training. The mean duration of follow-up for seven children was 17 months. The mean baseline VAS was 7.1. When compared with the baseline, VAS rating during the training period decreased with a mean difference of 3.0. The difference remained at 1.9 at 4 months after training had stopped. Other functional gains, such as improved sucking and swallowing, were identified. Six caregivers declined surgery. One child improved and did not require surgery. CONCLUSIONS Short-term follow-up of oro-motor training suggested beneficial outcome.

Abstract
The objective of this study was to evaluate the feasibility of ultrasonography-guided injections of botulinum toxin A into the parotid glands of children with severe drooling (sialorrhea). Excessive drooling is common in children with chronic neurologic disorders. Preliminary observations in adults suggest that injections of botulinum toxin A into the parotid glands can decrease drooling, but the optimal dose, sites of injection, and concomitant use of imaging during injections and its use for children have not been established. Ultrasonography was used to guide the injection of botulinum toxin (10-25 IU) into both parotid glands of nine children with excessive drooling. Subjective and objective measures of the severity of drooling were collected before and after botulinum toxin A injections. A booster injection was provided if the initial response was inadequate. Injections were well tolerated, and no adverse reactions were observed. Ultrasonography revealed that the parotid gland showed a variable depth, extent, and vascularization. Eight of nine patients needed a booster injection after 1 month. Objective measures of drooling severity were improved in seven of nine patients. However, subjective improvement was reported in only three of nine patients, and this improvement was functionally significant in only one patient. Although intraparotid injection of botulinum toxin A is safe and causes a reduction in saliva production in children, the doses used in this study did not result in functionally significant improvement. Higher doses of botulinum toxin A in the parotid glands or concomitant injections into the submandibular glands can increase the efficacy of these injections. Variability in size, depth, and vascular supply of the parotid gland suggests the importance of ultrasonography guidance for optimizing injections. These results underscore the need for further studies to establish the efficacy of this treatment in children.

Abstract
Drooling is problematic for some neurologically impaired children. Botulinum toxin A injection to salivary glands has effectively reduced drooling in adults but has only recently been used to treat children. This was a preliminary study to determine the efficacy and safety of botulinum toxin in children. Children identified as having severe daily drooling were enrolled. The preinjection assessment included measurement of the amount and frequency of drool. Each parotid gland was injected with 5 U of botulinum toxin A. Follow-up was for a minimum of 16 weeks. Nine children were enrolled, 4-17 years of age. All children had moderate or severe mental retardation. At week 4, all patients had a reduced drooling frequency and eight of nine patients had a reduction in the weight of saliva. Overall, five of nine parents (55%) deemed the treatment successful. This preliminary study demonstrates that botulinum toxin A is a relatively effective treatment for some children with significant drooling without serious side effects.

Abstract
OBJECTIVE To assess the safety and efficacy of intraglandular (parotid and submandibular) botulinum-A toxin (BTX-A) in the treatment of sialorrhea in children with cerebral palsy (CP). STUDY DESIGN Prospective, open-label, dose-escalation study. SETTING Tertiary care Children's Hospital. PATIENTS Twenty-two subjects between 8 and 21 years of age with CP and significant sialorrhea. INTERVENTION/TECHNIQUE The first 12 subjects were injected in only the submandibular gland and the second 10 in the submandibular and parotid glands. Injections were performed under ultrasound localization. The first group (divided into 3) received a total of 10, 20, or 30 units of BTX-A. The second group (divided into 3) received a standard of 30 units in the submandibular gland and 20, 30, or 40 units in the parotid glands. MAIN OUTCOME MEASURE(S) Drool quantification using a pre- and postinjection "drool rating scale," dental roll weights, and "drool quotient." Swallowing was evaluated pre- and postinjection with a formal speech therapy evaluation. RESULTS All subjects successfully underwent BTX-A injections without local or systemic complications. There were no adverse effects on swallowing. Objective "drool quantification" with dental rolls was extremely difficult in this population. Most indicative of results was the "drool rating" questionnaire and the "drool quotient." CONCLUSIONS BTX-A is a potentially safe and promising, minimally invasive treatment for sialorrhea in children with cerebral palsy.

Abstract
OBJECTIVE To study the outcome of 21 typically developing children who had been referred to the Saliva Control Clinic at the Royal Children's Hospital, Melbourne. METHOD Information was collected on various aspects of the child's health, oromotor function and severity of drooling. A follow-up telephone survey was completed by the parents of these children after a mean period of 3.4 years. Information was gathered regarding their child's drooling, current health, oromotor status and the usefulness of the clinic. RESULTS There was a statistically significant improvement (P < 0.01) in the saliva control measures analysed on follow-up. Thirteen children ceased to drool, three still drooled occasionally, and five continued to drool. The recommendations, mainly advice and referrals to other health professionals, were generally reported to be helpful by the parents. CONCLUSIONS This cohort of children was established retrospectively, and the study is therefore limited in both numbers and design. The results indicate that some typically developing children may be delayed in the development of saliva control. Parents and professionals can be reassured that this problem is likely to resolve.

Abstract
Tongue acupuncture is an innovative technique in traditional Chinese medicine. We have demonstrated that specific tongue acupoints are related to various functional domains. This study aimed to assess the efficacy of tongue acupuncture in children with neurologic disability who had severe drooling problems. We conducted an intent-to-treat study in a cohort of 10 children. A continuous course of tongue acupuncture was performed daily to five acupoints in the tongue for a total of 30 sessions. Standardized outcome measures of drooling were evaluated by a blinded assessor to study the efficacy at baseline and after a course of treatment. Statistically significant improvement was noted in the following outcome measures: (1) mean visual analog scale (VAS) decreased from 6.6 (pre-TAC) to 4.67 (post-TAC) (P = 0.002); (2) mean drooling quotient (DQ) decreased from 14.016% (pre-TAC) to 8.335% (post-TAC) (P = 0.0078); and (3) mean drooling score (DS) decreased from 7.4 (pre-TAC) to 4.4 (post-TAC) (P = 0.002). This study demonstrated the efficacy of tongue acupuncture as an adjunctive or alternative treatment for patients with drooling problems and can be integrated as part of the oromotor stimulation program, drooling program, and behavioral modification program before subjecting the patient to invasive surgical procedures on the salivary glands.

Abstract
PURPOSE Sialorrhea is the unintentional loss of saliva and other contents from the mouth. Most patients with this condition are elderly, requiring palliative treatment. These patients have neuropathology with associated poor performance status. Treatment prescribed for this disabling and distressing condition has often been of a surgical nature and described in young patients. It would be inapplicable to the elderly. The aim of this study was to review the role of radiation therapy in the management of sialorrhea. Previous reports are few in number and are cautionary because of adverse effects which have been described, including dryness of the mouth. METHODS AND MATERIALS A total of 34 patients were referred to the Department of Radiation Oncology, Palmerston North Hospital, between 1966 and August 1994, of whom only 1 patient received treatment prior to 1985. Three patients declined treatment and were, therefore, excluded from this review. Thirty-one patients, including 14 males and 17 females, of median age 72 years received 1 or more radiation treatments for sialorrhea. The patients were followed up for a median of 12 months, ranging from 6 months to 27 years. RESULTS Initially, 82% (28/34) of treatments were associated with a satisfactory response. Six patients relapsed, of whom five experienced relapse within 6 months of initial treatment. Two patients were re-treated, one of whom achieved a complete response. Up to the time of review 64% (23/36) of treatments maintained a satisfactory response. The varied fractionation regimens used were not shown to affect the response rate; low doses were shown to be as effective as higher doses, and were not associated with any significant acute or late side effects. Only 4 patients developed long-term side effects. However, response rates were superior for patients treated with electrons, as opposed to orthovoltage therapy, and in particular when electron energies greater than 7 megavolts were used (76% vs. 38% maintained response, p < 0.05). Responses were also superior for patients treated with radiation fields which encompassed both parotid and submandibular glands (74% vs. 33 % maintained response, p < 0.01). CONCLUSIONS Radiation therapy has proven to be a safe and effective treatment in this group of patients, thereby avoiding the adverse effects of anticholinergic medication and invasive surgical procedures.

Abstract
The authors performed six sialodochoplasties between 1991 and 1994 to treat drooling in six children who suffered from cerebral palsy. There were three boys and three girls, aged 13 to 22 years (mean, 16 years). All patients underwent parotid duct rerouting. The first four patients (group I) also underwent associated excision of submandibular ducts, and the last two patients (group II) benefited from rerouting of the submandibular ducts. In group I, results were considered good in two cases, fair in one case, and poor in one case. A fistula of the new Stenon duct appeared in one patient, which required excision and ligation followed by progressive involution of the parotid gland. Both group II patients had excellent and rapid results. The requirements leading to surgical decision are determined. The importance of physiotherapy is emphasized. Surgical techniques are described and discussed, as are objective criteria for the assessment of surgical results, namely salivary radioisotopic scanning.

Abstract
Drooling occurs commonly in children with cerebral palsy (CP). Surgical procedures, known as slalodochoplasties, are often performed for the control of drooling. These include major salivary gland excision, parasympathetic nerve section, duct ligation, and duct re-routing. Alterations in saliva amount, flow, and consistency occur following sialodochoplasty, and the resultant effect on dental homeostasis requires further investigation. This controlled study investigated 19 children with CP following sialodochoplasty (surgery group) and 75 children with CP treated nonsurgically (control group) who attended our hospital. Dental caries experience-including dmft, DMFT, and partial DMFS scores of mandibular incisors and canines only-plaque index, and enamel developmental defects index were recorded. Saliva buffering capacity and bacterial counts were assessed. The surgical group (median DMFT = 5.00) had significantly more dental caries when compared with the control group (median DMFT = 0.00), Wilcoxon Signed-rank Test, P < 0.0001. This study has shown that children with CP following sialodochoplasty have increased risk of dental caries when compared with those treated nonsurgically for drooling. Although no caries predictors were identified, alterations to the caries-protective role of saliva are considered the likely cause. Children who undergo this procedure should receive intensive pre- and postsurgical preventive dental therapy.

Abstract
Thirty-nine patients who had undergone transposition of the submandibular ducts and unilateral ligation of a parotid duct for saliva control were followed up six years after surgery. Overall improvement was documented according to a drooling quotient, drooling severity and drooling frequency measures. Despite this superficially favourable outcome, a significant proportion of patients (39 per cent) or their caregivers had not found the surgery helpful. Complications included ranula formation, complaints of dry mouth, difficulty with swallowing, and changes in the consistency of oral secretions. More knowledge is needed of the likely outcomes of this procedure in individual patients, so that appropriate advice can be given and complications minimised.
