Speech-language and hearing complaints of children and adolescents with brain tumors

Speech-Language Pathology Services in Pediatric Cancer: Survey and Interview Data on Caregiver Experiences

Pediatric cancer and its treatment can cause disruption in typical child development, including the development of speech, language, and swallowing skills. Despite the potential for significant impact on communication and swallowing, speech-language pathologists are not routinely involved in the care teams of children diagnosed with cancer. The goal of this investigation was to enhance the understanding of the speech-language pathology services rendered and caregivers' perspectives on the current needs of children and adolescents who have undergone cancer treatment. Caregiver's perspectives offer unique insights and are beneficial when utilizing a person- and family-centered care framework. Eleven caregivers of children treated for cancer completed an online survey, and an additional three caregivers participated in a semistructured interview. Results provided insight into caregivers' perspectives regarding speech-language pathology-related needs and services. Survey results and thematic analysis of the semistructured interviews indicated the need for involvement of speech-language pathology services during and after cancer treatment. Cancer diagnoses and oncological treatment occur during key developmental periods, and may negatively impact children's speech, language, and swallowing abilities. Speech-language pathologists are uniquely positioned to provide support for children undergoing or following cancer treatment.

Features Associated With Weight Loss and Growth Stunting for Young Children During Cancer Therapy

Features associated with malnutrition are poorly elucidated in pediatric cancer care. We aimed to better understand characteristics associated with weight-for-height (WHZ) and height-for-age (HAZ) changes for infants and young children during cancer treatment. This retrospective study included 434 patients diagnosed <3 years old from 2007 to 2015 at a large pediatric cancer center. Patients starting treatment outside our center, those with relapsed or secondary malignancies, or with inaccurate information were excluded. Abstracted weights and heights for a 24-month period after treatment initiation were converted to sex-specific and age-specific z scores. Although not statistically different at baseline, patients with hematologic malignancies gained weight over time, while other tumor types did not. Higher treatment intensity and younger age at diagnosis increased odds of clinically significant weight loss. Older children had higher HAZ at diagnosis and HAZ also significantly decreased over time for all examined risk factors, which is distinctly different from patterns in WHZ over time. In conclusion, WHZ and HAZ are affected differently by cancer treatment in infants and young children. We identify key risk factors for weight loss and growth stunting which will be necessary to develop prospective trials to examine anthropometric, biochemical, and patient recorded outcomes around nutrition.

The Parent-Child Patient Unit (PCPU): Evidence-Based Patient Room Design and Parental Distress in Pediatric Cancer Centers

Children with cancer are frequently hospitalized during diagnosis and treatment. Since the early 1980s, parents are co-admitted because their presence positively affects children’s adjustment to hospitalization and reduces post-traumatic stress. However, the size and overall architectural design of the rooms were never adapted to the doubling of the occupancy rate. Since studies show that many parents experience high levels of distress due to their child’s illness, the purpose of this study was to investigate the impact of the architecture of the aged patient rooms on parental distress. A video observation targeted parent–child interaction related to five architectural determinants: (a) function and place of interaction, (b) distance between parent and child, (c) used space, (d) withdrawal, and (e) duration of the interaction. A total of 22 families were included in two Dutch children’s hospitals. Results show a significant association between parental distress and three architectural determinants: The less anxious the parents were and the better they estimated their child’s well-being, the more distance they created between themselves and their child, and the more space, privacy, and withdrawal options were used. These findings are discussed within a new patient room typology, the parent–child patient unit (PCPU), which reacts to the evident association of parental distress and the design.

Communication and swallowing outcomes of children diagnosed with childhood brain tumor or leukemia: A systematic review

The purpose of this systematic review was to appraise and synthesize evidence on communication and swallowing outcomes associated with childhood brain tumor or leukemia (CBTL). A comprehensive database and grey literature search was conducted. Studies included: (a) peer-reviewed research published between 1998 and 2019, (b) English language, (c) children aged 0-16 years diagnosed with CBTL, and (d) used outcome measures focused on communication and/or swallowing. Quality assessment was completed and certainty of evidence rated using Grading of Recommendations Assessment, Development and Evaluation (GRADE). Fifty-seven studies met inclusion criteria: 46 examined communication, seven examined swallowing, and four considered both. Most studies were descriptive and prospective. Communication difficulties were frequently reported and apparent at one or more points from diagnosis to survivorship. Swallowing difficulties were frequently reported during oncology treatment. Despite quality assessment revealing methodological shortcomings, results have implications for clinical services and future research.

Nutrition & Exercise Interventions in Pediatric Patients with Brain Tumors: A Narrative Review

Brain tumors have been the most common pediatric solid tumor and leading cause of morbidity and mortality. Improved survival emphasizes the importance of adverse treatment effects especially related to nutrition and exercise. Although studies have examined nutrition and exercise outcomes, few randomized trials exist. This narrative review included a systematic literature search with analysis of controlled or single group studies examining clinical and quality-of-life impact of nutrition or exercise interventions. Seven articles were included. Three nutrition studies demonstrated improvement with proactive feeding tubes, nutritional supplementation, and nutritional status. Two exercise studies showed improvement in measures of fitness and neuroanatomy with exercise in pediatric brain tumor survivors; two cohort studies demonstrated a link between quality of life and physical activity. Preliminary studies show nutrition and exercise may improve physical well-being and quality of life, suggesting future controlled studies are warranted to inform clinical care of children with brain tumors.

Incidence and risk factors of communication, swallowing, and orofacial myofunctional disorders in children and adolescents with cancer and benign neoplasms

PURPOSE

To describe the incidence and risk factors of communication, swallowing, and orofacial myofunctional disorders in a cohort of children and adolescents with cancer and benign neoplasms.

METHODS

A prospective cohort study conducted with children aged ⩾ 2 years and adolescents of both genders admitted at the Pediatric Oncology Department of the Instituto Nacional de Câncer (INCA) between March 2014 and April 2015. Study participants were submitted to a Speech-Language Pathology (SLP) assessment at three different times: (T1) at hospital admission; (T2) six months after admission; (T3) one year after admission.

RESULTS

One hundred and sixty individuals were evaluated. At the time of hospital admission, 68 individuals (42.5%) presented with some type of SLP disorder. After one year of follow-up, 22.8% of the patients had developed new impairments. The occurrence of new speech-language disorders had a statistically significant association with the tumor site. In the risk analysis for the development of speech-language disorders with respect to the primary tumor site, compared to other sites, the central nervous system (CNS) tumor group was 8.29 times more likely to present some new alterations, while the head and neck (HN) tumor group had a 10.36-fold higher risk.

CONCLUSION

An incidence of 22.8% for communication, swallowing, and orofacial myofunctional disorders was observed. The development of these disorders was greater in individuals with tumors in the CNS and in the HN region.

Management of Vocal Fold Paralysis and Dysphagia for Neurologic Malignancies in Children

Objectives:

To evaluate our experience with a significant number of brain malignancy–related vocal fold paralysis patients and their response to vocal cord–related therapies.

Background:

Vocal fold paralysis is a potentially devastating complication of various types of pediatric diseases and surgeries that can lead to significant vocal and swallowing difficulties. While there is significant data in the literature on outcomes of children treated for vocal fold paralysis following cardiac or thyroid surgery, there is a scarcity of such information on children following the treatment of neurologic malignancy.

Methods:

Records of 19 patients at a tertiary center who were treated for neurologic malignancies and developed either unilateral or bilateral vocal fold paralysis were reviewed for vocal fold pathology and vocal fold paralysis treatment-related variables, including initial diagnosis, management with observation or speech therapy, duration of therapy, pre- and postintervention swallow studies, and surgical intervention.

Results:

Bilateral vocal fold paralysis was noted in 26% (5/19) patients. Eighty-four percent (16/19) of patients had stable or improved ability to vocalize and swallow following therapy. There was no statistically significant difference in speech or swallowing improvement after speech therapy alone or speech therapy in combination with injection laryngoplasty ( P = .25). No complications were noted with surgical intervention.

Conclusions:

Patients with vocal fold paralysis secondary to neurologic malignancy can have an improvement in speech and swallowing after a variety of treatments, including speech therapy or early injection laryngoplasty. There was no statistically significant difference in improvement based on the type of intervention utilized. A larger sample size is needed to conclude whether surgical intervention combined with speech therapy leads to more rapid and significant functional improvement than speech therapy alone.

Loss of IDH2 Accelerates Age-related Hearing Loss in Male Mice

Isocitrate dehydrogenase (IDH) 2 participates in the TCA cycle and catalyzes the conversion of isocitrate to α-ketoglutarate and NADP⁺ to NADPH. In the mitochondria, IDH2 also plays a key role in protecting mitochondrial components from oxidative stress by supplying NADPH to both glutathione reductase (GSR) and thioredoxin reductase 2 (TXNRD2). Here, we report that loss of Idh2 accelerates age-related hearing loss, the most common form of hearing impairment, in male mice. This was accompanied by increased oxidative DNA damage, increased apoptotic cell death, and profound loss of spiral ganglion neurons and hair cells in the cochlea of 24-month-old Idh2^−/− mice. In young male mice, loss of Idh2 resulted in decreased NADPH redox state and decreased activity of TXNRD2 in the mitochondria of the inner ear. In HEI-OC1 mouse inner ear cell lines, knockdown of Idh2 resulted in a decline in cell viability and mitochondrial oxygen consumption. This was accompanied by decreased NADPH redox state and decreased activity of TXNRD2 in the mitochondria of the HEI-OC1 cells. Therefore, IDH2 functions as the principal source of NADPH for the mitochondrial thioredoxin antioxidant defense and plays an essential role in protecting hair cells and neurons against oxidative stress in the cochlea of male mice.

Prevalence of communication, swallowing and orofacial myofunctional disorders in children and adolescents at the time of admission at a cancer hospital

PURPOSE

Describe the prevalence of communication, swallowing and orofacial myofunctional disorders in a group of children and adolescents at the time of registration at a cancer hospital.

METHODS

A cross-sectional study conducted with children aged ≥2 and adolescents, of both genders, admitted to the Pediatric Oncology Section of the Instituto Nacional de Câncer José de Alencar Gomes da Silva (INCA) from March 2014 to April 2015 for investigation and/or treatment of solid tumors. A protocol was used to record the sociodemographic and clinical information and findings of the speech-language pathology clinical evaluation, which included aspects of the oral sensorimotor system, swallowing, speech, language, voice, and hearing.

RESULTS

Eighty-eight children/adolescents (41.3%) presented some type of speech-language disorder. The most frequent speech-language disorders were orofacial myofunctional disorder, dysphonia, and language impairments, whereas the less frequent ones were dysacusis, tongue paralysis, and trismus. Site of the lesion was the clinical variable that presented statistically significant correlation with presence of speech-language disorders.

CONCLUSION

High prevalence of speech-language disorders was observed in children and adolescents at the time of admission at a cancer hospital. Occurrence of speech-language disorders was higher in participants with lesions in the central nervous system and in the head and neck region.

Swallowing difficulties with medication intake assessed with a novel self-report questionnaire in patients with systemic sclerosis - a cross-sectional population study

OBJECTIVES

To assess subjective swallowing difficulties (SD) with medication intake and their practical consequences in patients suffering from systemic sclerosis (SSc) with a novel self-report questionnaire.

DESIGN AND SETTING

Based on a systematic literature review, we developed a self-report questionnaire and got it approved by an expert panel. Subsequently, we sent the questionnaire by post mail to SSc patients of the European Center for the Rehabilitation of Scleroderma Rheinfelden, Switzerland.

PARTICIPANTS

Patients were eligible if they were diagnosed with SSc, treated at the center, and were of age ≥18 years at the study start.

MAIN OUTCOME MEASURES

Prevalence and pattern of SD with oral medication intake, including localization and intensity of complaints.

RESULTS

The questionnaire consisted of 30 items divided into five sections Complaints, Intensity, Localization, Coping strategies, and Adherence. Of the 64 SSc patients eligible in 2014, 43 (67%) returned the questionnaire. Twenty patients reported SD with medication intake (prevalence 47%), either currently (11; 26%) or in the past that had been overcome (9; 21%). Self-reported SD were localized mostly in the larynx (43%) and esophagus (34%). They were of moderate (45%) or strong to unbearable intensity (25%). Modification of the dosage form was reported in 40% of cases with SD. Adherence was poor for 20 (47%) patients and was not associated with SD (p=0.148).

CONCLUSION

Our novel self-report questionnaire is able to assess the pattern of complaints linked to medication intake, that is, localization and intensity. It may serve as a guide for health care professionals in selecting the most suitable therapy option, enabling tailored counseling to reduce inappropriate medication modifications.

Speech Pathology Services to Children With Cancer and Nonmalignant Hematological Disorders

Children with cancer and nonmalignant hematological disorders may require speech pathology (SP) support; however, limited evidence is available describing prevalence and severity of swallowing/feeding and communication impairments in this population. A retrospective chart review of 70 children referred to SP at the newly formed Queensland Children’s Cancer Centre was conducted to describe the prevalence and severity of swallowing/feeding and communication dysfunction, and the association between impairment, oncology and hematology diagnosis, and service utilization (time and occasions of service). Swallowing/feeding disorders were the most commonly observed impairments at initial assessment (58.6%). Children with central nervous system tumors ( P = .03) and nonmalignant hematological disorder ( P = .03) had significantly higher rates of feeding impairment than other oncology and hematology diagnostic groups. Children with central nervous system tumors had the highest rates of oral phase ( P = .01) and pharyngeal phase ( P = .01) dysphagia (swallowing disorder). No significant difference was found between diagnostic groups for intensity of SP service delivery. Prospective research is required to examine prevalence and severity of disorders, and service utilization in a more established clinic, and to investigate interactions between cancer treatment and swallowing/feeding and communication dysfunction.

Intensity modulated radiation therapy or stereotactic fractionated radiotherapy for infratentorial ependymoma in children: a multicentric study

This study was to evaluate the treatment dosimetry, efficacy and toxicity of intensity modulated radiation therapy (IMRT) and fractionated stereotactic radiotherapy (FSRT) in the management of infratentorial ependymoma. Between 1999 and 2007, seven children (median age, 3.1 years) with infratentorial ependymoma were planned with either IMRT (3 patients) or SFRT (4 patients), the latter after conventional posterior fossa irradiation. Two children underwent gross total resection. Median prescribed dose was 59.4 Gy (range, 55.8-60). The median follow-up for surviving patients was 4.8 years (range, 1.3-8). IMRT (median dose, 59.4 Gy) and FSRT (median dose, 55.8 Gy) achieved similar optimal target coverage. Percentages of maximum doses delivered to the cochleae (59.5 vs 85.0% Gy; P = 0.05) were significantly inferior with IMRT, when compared to FSRT planning. Percentages of maximum doses administered to the pituitary gland (38.2 vs 20.1%; P = 0.05) and optic chiasm (38.1 vs 14.1%; P = 0.001) were, however, significantly higher with IMRT, when compared to FSRT planning. No recurrences were observed at the last follow-up. The estimated 3-year progression-free survival and overall survival were 87.5 and 100%, respectively. No grade >1 acute toxicity was observed. Two patients presented late adverse events (grade 2 hypoacousia) during follow-up, without cognitive impairment. IMRT or FSRT for infratentorial ependymomas is effective and associated with a tolerable toxicity level. Both treatment techniques were able to capitalize their intrinsic conformal ability to deliver high-dose radiation. Larger series of patients treated with these two modalities will be necessary to more fully evaluate these delivery techniques.

Language skills following risk-adapted treatment for medulloblastoma

OBJECTIVE

Recent research findings suggested that children treated for medulloblastoma (MB) may experience undiagnosed language difficulties following treatment. The aim of this report was to investigate language skills in an adolescent following treatment for MB.

METHODS

This single case study profiles the language skills of GCG, a female aged 14;1 years, who was treated with risk-adapted cranial radiation therapy (CRT) for MB 4 years prior to language assessment.

RESULTS

Difficulties recalling verbal information of increasing length and complexity and reduced competence with language requiring critical thinking and complex cognitive processing were identified.

CONCLUSION

The findings suggest that prospective language assessment and monitoring should routinely be undertaken in children following treatment for MB, even when less-intense treatments are delivered to reduce adverse neurocognitive outcomes, due to the vulnerability of the developing brain to CRT.

Nutritional problems in children treated for medulloblastoma: implications for enteral nutrition support

BACKGROUND

The aim of this study was to identify the nature and severity of nutritional problems associated with the current treatment of medulloblastoma and to identify any risk factors for nutritional morbidity during treatment.

PROCEDURE

A multicentre retrospective audit of medical and dietetic notes of 41 children treated for medulloblastoma in three UK paediatric oncology centres was undertaken. Data on nutritional status, nutritional support, mutism, swallowing and common toxicity criteria (CTC) scores for vomiting, constipation and mobility were collected at defined points in treatment from diagnosis until 12 months post-treatment.

RESULTS

Significant problems including weight loss, vomiting and constipation were highlighted early on in treatment. The majority of patients were well nourished at diagnosis with a mean percentage weight: height of 99.8%, however nutritional status started to decline early in treatment during radiotherapy, coinciding with 49% of patients having grade 1 or above CTC score for vomiting and constipation. The decline in nutritional status continued, peaking by course 2 of chemotherapy with a mean weight loss of 8.2% since diagnosis. Proactive supplementary feeding early in treatment by one of the three centres demonstrated a superior nutritional outcome when compared statistically to the two centres that fed only as a response to nutritional decline.

CONCLUSION

The study highlighted significant morbidity associated with the current treatment of medulloblastoma. Findings suggest the need to consider earlier proactive nutritional intervention to prevent nutritional decline during treatment. These early nutritional problems may be related to toxicities of radiotherapy and concomitant vincristine.
