TENS was able to increase the salivary flow rate of patients with RT-induced hyposalivation.
Hyposalivation is a frequent complication after treatment with radiotherapy. To evaluate the efficacy of transcutaneous electrical nerve stimulation (TENS) on the hyposalivation assessed through stimulated salivary flow (SSF). In this clinical trial, 68 patients (with hyposalivation) were randomly assigned to control (n = 31) or TENS (n = 37) group. Participants in control group received habitual care, while those in TENS group received 8 sessions (20 minutes each) delivered twice a week for four weeks. The electrodes were attached over the skin covering the salivary glands. The electric pulse was adjusted at a frequency of 50 Hz, pulse width of 250 μs and as intense as tolerated. SSF was evaluated through sialometry. Self‐perception of salivary flow (SPSF) and quality of life (QL) was evaluated prior to, during and at 1, 3 and 6 months after treatment. Although no changes were observed in the control group for SSF at any timepoints, TENS group showed a progressive increase in SSF from the third session until the end of the treatment. Significant improvements were also found in SPSF, especially when the SSF reached values ≥0.7 mL/minute. The most expressive results were evident at 6 months after treatment so that SSF, SPSF and QL remained significantly higher (F = 9.5, P = 0.0001; H = 143.77, P < 0.0001; χ2 = 9.162, P = 0.02, respectively). TENS was effective at improving hyposalivation. The benefits on SSF, SPSF and QL give base to a promising therapeutic strategy for patients with hyposalivation after radiotherapy treating head and neck cancer.
Purpose: to describe the speech therapy aspects of patients treated by the palliative care team in a hospital. Methods: an observational and cross-sectional study, performed from medical records of patients treated under Palliative Care Program, in a hospital, from July to September 2018. Information from the anamnesis and speech-language assessments, which were analyzed by frequency measures, were collected. Results: the sample was composed by 41 medical records, including 25 males and 16 females, with an average age of 61.2 years and hospitalization average time of 20.7 days. Oral feeding was present in 73% of the sample. It was observed that 24% of the patients had impaired expressive language, 56% had reduced maximum phonation times and 34% showed altered mobility phonoarticulatory organs. For swallowing, 22% showed difficulty in some consistency. A nutritional feeding was verified in 74% of the sample and the remaining was making use of comfort feeding. In relation to assistance, 46% of the sample was under management, 7% in therapy, and the remaining did not have follow-up indication. Conclusion: relevant alterations to orofacial motricity, voice, language and swallowing were found in patients under palliative care.
RESUMO Objetivo Identificar os efeitos de medidas profiláticas, não farmacológicas, sobre a progressão da disfagia em pacientes com câncer de cabeça e pescoço submetidos a radioterapia. Estratégia de pesquisa A busca foi realizada nas bases de dados Medline (via PubMed), Scopus e Embase, assim como na literatura cinzenta. Critérios de seleção Foram incluídos ensaios clínicos randomizados, com pacientes adultos (≥ 18 anos) e diagnóstico de câncer de cabeça e pescoço, tratados com radioterapia (associada ou não à cirurgia e quimioterapia) submetidos a protocolos não farmacológicos de prevenção da disfagia. Análise dos dados O risco de viés foi avaliado por meio da escala PEDRO e a qualidade global da evidência foi avaliada de acordo com o instrumento GRADE. Resultados Foram considerados elegíveis 4 estudos, e desses, dois foram incluídos na metanálise. O resultado favoreceu o grupo intervenção, com diferença média de 1,27 [IC 95%: 0,74 à 1,80]. Houve baixa heterogeneidade e a pontuação média para risco de viés foi de 7,5 de um total de 11 pontos. A falta de detalhamento nos cuidados com os vieses de seleção, performance, detecção, atrito e de relato contribuíram para o julgamento da qualidade da evidência, considerada baixa. Conclusão Medidas profiláticas de contenção da disfagia podem promover importantes benefícios sobre a ingesta oral dos pacientes com câncer de cabeça e pescoço, quando comparados aqueles que não realizaram tal medida terapêutica ao longo da radioterapia.
Purpose To identify the effects of prophylactic, non-pharmacological measures on the progression of dysphagia in patients with head and neck cancer undergoing radiotherapy. Research strategies The search was performed in Medline (via PubMed), Scopus, and Embase databases, as well as in the gray literature. Selection criteria Randomized clinical trials were included, with adult patients (≥ 18 years old) and diagnosed with head and neck cancer, treated with radiotherapy (with or without surgery and chemotherapy), and submitted to non-pharmacological protocols for the prevention of dysphagia. Data analysis The risk of bias was assessed using the PEDRO scale and the overall quality of evidence was assessed using the GRADE instrument. Results Four studies were considered eligible, and of these, two were included in the meta-analysis. The result favored the intervention group, with a mean difference of 1.27 [95% CI: 0.74 to 1.80]. There was low heterogeneity and the mean score for risk of bias was 7.5 out of 11 points. The lack of detail in the care with selection, performance, detection, attrition, and reporting biases contributed to the judgment of the quality of the evidence, considered low. Conclusion Prophylactic measures to contain dysphagia can promote important benefits on the oral intake of patients with head and neck cancer when compared to those who did not undergo such a therapeutic measure during radiotherapy.

Objetivo: Descrever a atuação fonoaudiológica hospitalar no paciente oncológico disfágico. Métodos: Estudo transversal, retrospectivo, descritivo, quantitativo, desenvolvido em um hospital oncológico. A amostra foi composta por prontuários de pacientes com câncer que realizaram acompanhamento fonoaudiológico para disfagia. Foram aplicados indicadores fonoaudiológicos de disfagia e comparada a escala de ingestão de alimentação por via oral (FOIS) antes e após terapia fonoaudiológica. Resultados: A amostra contou com 400 prontuários, 189 foram incluídos no GA (grupo ambulatório) e 211 no GI (grupo internação). A média geral da idade da amostra corresponde a 60,35±12,63, sendo o predomínio de homens 263 (65,8%). Quanto às neoplasias apresentadas pelos pacientes: 247 cabeça e pescoço e 43 esôfago e estômago. No GA 143 (75,7%) pacientes melhoraram a escala FOIS pós-terapia, 33 pacientes (17,5%) mantiveram o mesmo nível e 13 pacientes (6,9%) apresentaram piora na FOIS após o processo terapêutico. No GI 103 (48,8%) pacientes melhoraram pós-terapia, 81 pacientes (38,4%) mantiveram o mesmo nível na escala, e 27 pacientes (12,8%) apresentaram piora após a terapia fonoaudiológica. Conclusão: O estabelecimento de indicadores na atuação junto ao paciente disfágico permite identificar e quantificar as melhorias dos processos assistenciais, trazendo benefícios diretos aos pacientes, auxiliando na caracterização da população atendida, otimizando e aprimorando os processos e resultados, visando o aprimoramento da qualidade dos serviços prestados, bem como redução do tempo de internação e dos custos hospitalares.
