Validation of the French Versions of the Speech Handicap Index and the Phonation Handicap Index in Patients Treated for Cancer of the Oral Cavity or Oropharynx

<b><i>Context:</i></b> Nowadays, clinical tools are available to evaluate the functional impact of speech disorders in neurological conditions, but few are validated in oncology. Because of their location, cancers of the upper aerodigestive tract directly impact patients’ communication skills. Two questionnaires exist in French, the Speech Handicap Index (SHI) and the Phonation Handicap Index (PHI), but none are specifically validated for the head and neck cancer population. Our aim is to evaluate the validity of these 2 questionnaires in a population of patients treated for oral cavity or oropharyngeal cancer. <b><i>Material and Method:</i></b> Eighty-seven patients treated for cancer of the oral cavity or oropharynx, and 21 controls filled in the questionnaires during a consultation or 1-day hospitalization. Validation was studied by the analysis of convergent and discriminant validity, clinical validity, criterion validity, and internal consistency. <b><i>Results:</i></b> The 2 questionnaires present a coherent structure in 2 distinct dimensions for the SHI, and in 3 dimensions for the PHI. Both tools discriminate patients and healthy subjects (<i>p</i> value &#x3c;0.001, Mann-Whitney test). The comparison of the SHI and PHI scores with the “social role functioning” dimension of the Medical Outcome Study Short Form 36 chosen as a reference shows similar performances for the 2 questionnaires (ρ &#x3e; 0.42). Lastly, the internal consistency is good (Cronbach’s α &#x3e; 0.71). <b><i>Conclusion:</i></b> In patients treated for oral cavity or oropharyngeal cancer, the SHI and PHI are 2 valid and reliable tools for the self-assessment of speech disability. A limitation can be found about criterion validity, because a true gold standard does not exist at the moment. However, the reduced number of questions of the PHI, which implies a shorter completion, leads to prefer this tool over the SHI.

Dyssynchrony and perinatal psychopathology impact of child disease on parents-child interactions, the paradigm of Prader Willi syndrom

BACKGROUND

Infant-mother interaction is a set of bidirectional processes, where the baby is not only affected by the influences of his caregiver, but is also at the origin of considerable modifications. The recent discovery of biological correlates of synchrony during interaction validated its crucial value during child development. Here, we focus on the paradigmatic case of Prader-Willi Syndrome (PWS) where early endocrinal dysfunction is associated with severe hypotonia and early feeding disorder. As a consequence, parent-infant interaction is impaired. In a recent study (Tauber et al., 2017), OXT intranasal infusion was able to partially reverse the feeding phenotype, infant's behavior and brain connectivity. This article details the interaction profile found during feeding in these dyads and their improvement after OXT treatment.

METHODS

Eighteen infants (≤6months) with PWS were recruited and hospitalized 9days in a French reference center for PWS where they were treated with a short course of intranasal OXT. Social withdrawal behavior and mother-infant interaction were assessed on videos of feeding before and after treatment using the Alarm Distress Baby (ADBB) Scale and the Coding Interactive Behavior (CIB) Scale. Raters were blind to treatment status.

RESULTS

At baseline, infants with PWS showed hypotonia, low expressiveness of affects, fatigability and poor involvement in the relationship with severe withdrawal. Parents tended to adapt to their child difficulties, but the interaction was perturbed, tense, restricted and frequently intrusive with a forcing component during the feeding situation. After OXT treatment, infants were more alert, less fatigable, more expressive, and had less social withdrawal. They initiated mutual activities and were more engaged in relationships through gaze, behavior, and vocalizations. They had a better global tonicity with better handling. These modifications helped the parents to be more sensitive and the synchrony of the dyad was in a positive transactional spiral.

CONCLUSION

Dys-synchrony can be induced by children's pathology as well as parental pathology with emotional and developmental impact in the both cases. The PWS paradigm shows us the necessity to sustain early parents-child relationship to avoid establishment of a negative transactional pattern of interaction that can impact child's development.

The Use of Oxytocin to Improve Feeding and Social Skills in Infants With Prader-Willi Syndrome

BACKGROUND AND OBJECTIVES

Patients with Prader-Willi syndrome (PWS) display poor feeding and social skills as infants and fewer hypothalamic oxytocin (OXT)-producing neurons were documented in adults. Animal data demonstrated that early treatment with OXT restores sucking after birth. Our aim is to reproduce these data in infants with PWS.

METHODS

We conducted a phase 2 escalating dose study of a short course (7 days) of intranasal OXT administration. We enrolled 18 infants with PWS under 6 months old (6 infants in each step) who received 4 IU of OXT either every other day, daily, or twice daily. We investigated the tolerance and the effects on feeding and social skills and changes in circulating ghrelin and brain connectivity by functional MRI.

RESULTS

No adverse events were reported. No dose effect was observed. Sucking assessed by the Neonatal Oral-Motor Scale was abnormal in all infants at baseline and normalized in 88% after treatment. The scores of Neonatal Oral-Motor Scale and videofluoroscopy of swallowing significantly decreased from 16 to 9 (P < .001) and from 18 to 12.5 (P < .001), respectively. Significant improvements in Clinical Global Impression scale scores, social withdrawal behavior, and mother-infant interactions were observed. We documented a significant increase in acylated ghrelin and connectivity of the right superior orbitofrontal network that correlated with changes in sucking and behavior.

CONCLUSIONS

OXT is well tolerated in infants with PWS and improves feeding and social skills. These results open perspectives for early treatment in neurodevelopment diseases with feeding problems.

[Validation of a self assessment for speech disorders (Phonation Handicap Index)]

OBJECTIVE

The aim of this work is the psychometric validation of a self assessment questionnaire about speech in dysarthria.

MATERIALS AND METHODS

A prospective study was performed on 91 persons to analyze reliability and validity of this new questionnaire. It is composed of 25 items subdivided in 3 domains: Physical, functional and emotional. We first compared 17 normal speakers to 21 dysarthric patients. Then we analysed the intra-individual variability with 53 patients who completed the questionnaire twice with two weeks interval between the completion. The statistical analysis verified internal consistency of each item, intra-subject reliability was analyzed through Pearson test and clinical validity was calculated through the non parametric Mann Whitney test.

RESULTS

The internal consistency reliability was correct (Cronbach's alpha > 0.9). It appeared a statically significant difference between normal speakers and dysarthric patients (p < 0.05). The correlations to the handicap and severity felt were fair ensured us of the content's validity. However the absence of difference for 5 items drove us to eliminate them. Also, analysis the test / retest by the correlation matrix allowed to delete 5 other questions. The obtained total score was 0,861. As for the validity of contents, the correlations in the handicap and in the degree of severity felt by the dysarthric patients were satisfactory.

CONCLUSION

The results of this study allows to resume the validation of this questionnaire, its short form of 15 items is particularly adapted to dysarthric patients. It now remains to test its reliability with the medical evolution of the patients. We propose to name it "Phonation Handicap Index".

[Study of the predictive value of detection tests for silent aspirations]

Screening for aspiration in patients with swallowing disorders is important in preventing complications. The tests used in this regard are insufficient due to silent aspiration relating to abnormal protective reflexes in many patients with swallowing problems.

OBJECTIVE

The aim of this study is to determine the predictive values of simple tests in screening for silent aspiration.

MATERIAL AND METHOD

The reference test used was videofluoroscopic examination on swallowing. In the presence of aspiration (FR+) the presence (ME+) or not (ME-) of a cough of throat clearing was noted. The tests being studied were a nasal test with isotonic saline and swallowing according to a set time.

RESULTS

For screening for aspiration the presence of a "wet voice" was considered to be a sign of reduced protective reflexes. 1) During the nasal test, the results are 100% for the positive predictive value (VPp) and 83.3% for the negative predictive value (VPn); 2) These results are respectively 84.6% and 35.9% during the swallowing test. Regarding screening for silent aspiration, 1) during the nasal test, the results are 62.5% for the positive predictive value (VPp) and 36.3% for the negative predictive value (VPn); 2) These results are respectively 54.5% and 26.6% during the swallowing test.

CONCLUSION

This preliminary study points out the lack of predictive value of the nasal test and the swallow test for the silent aspirations. However the results could be useful for other researchers developing other tests in this area.

[Positioning in the oropharyngeal dysphagia]

Sitting body posture and the movements for the feeding gesture are interdependent and can worsen an oropharyngeal dysphagia. Their management will have a direct impact on the patient's handicap and will be able to decrease the complications. Clinical process aiming at placing a person having postural disorders, positioning will ensure a base adapted to the person, comfortable, allowing mobility and independence. It requires a methodical accompaniment: evaluation, test, validation, control of adapted equipment for the patient and gesture readjustment.

[Early education for children with Prader-Willi syndrome]

MATERIAL AND METHOD

A cohort of 21 children (under 42 months of age) with Prader-Willi syndrome were followed in a longitudinal way by the referral center team with evaluation of language and cognitive function (every six months).

RESULTS

Disorders seen between birth and the second year are primarily related to hypotonia with oropharyngeal dysphagia and impact on the pre-lingual phase of communication. After 2 years the psychomotor delay and the disorders of language acquisition effect development. When compared to patients who had treatment after 4 years and with data published in the literature, those patients with an early diagnosis and early treatment using kinesitherapy and logopedy showed faster linguistic acquisition. However articulation disorders still remain.

CONCLUSION AND RECOMMENDATIONS

This work highlights the importance of early readaptation associating kinesitherapy, logopedy and psychomotoricity which can improve the cognitive phenotype of these children.
