The golden jackal (Canis aureus): A new host for Echinococcus multilocularis and Trichinella britovi in Switzerland.

INTRODUCTION: The golden jackal (Canis aureus) is a wild canid new to Switzerland. It is an officially monitored species and all deceased individuals are submitted for post-mortem examination to collect baseline health data. This includes parasitological examinations, with an emphasis on zoonotic, reportable infections, such as those caused by Trichinella spp. or Echinococcus spp. From 2016 to 2021, five golden jackals originating from four Swiss cantons were submitted for full post-mortem examination. In one case only organ samples were available, and therefore parasitological examination was not possible. Parasite stages recovered during necropsy, as well as by routine coproscopical techniques, were morphologically identified. Taeniid eggs and adult tapeworms were processed for molecular species identification. Additionally, tongue and diaphragm were analysed for Trichinella spp. by the artificial digestion technique followed by multiplex-PCR in positive cases. Of the four jackals investigated for parasites, hookworm eggs were detected in one animal, both adult worms and eggs of Echinococcus multilocularis were present in another case, and one animal was free of parasites. Eggs of E. multilocularis as well as eggs of Toxocara canis and sporocysts of Sarcocystis sp. were detected in the intestinal content, and Trichinella britovi larvae were found in the muscle samples of the last case. The health monitoring programme in place for protected carnivores in Switzerland allowed us to add the golden jackal to the list of hosts for the endemic zoonotic parasites E. multilocularis and T. britovi in this country. Hunters, farmers, and other persons who could come in contact with golden jackals should be aware of the associated health risk and handle faeces and carcasses with caution.

INTRODUCTION: Le chacal doré (Canis aureus) est un canidé sauvage nouvellement présent en Suisse. Il s'agit d'une espèce officiellement surveillée et tous les individus morts sont soumis à un examen post-mortem afin de recueillir des données sanitaires de base. Cela inclut un examen parasitologique mettant l'accent sur les infections zoonotiques à déclaration obligatoire, telles que celles causées par Trichinella spp. ou Echinococcus spp. De 2016 à 2021, cinq chacals dorés originaires de quatre cantons suisses ont été soumis à un examen post-mortem complet. Dans un cas, seuls des échantillons d'organes ont été envoyés, l'examen parasitologique n'a pas été possible pour cet animal. Les stades parasitaires trouvés lors de l'examen pathologique et de la coprologie de routine ont été identifiés morphologiquement. Les espèces de ténias (œufs et stades adultes) ont été déterminées par des techniques de biologie moléculaire. En outre, la recherche de Trichinella spp. a été effectuée sur du tissu musculaire lingual et diaphragmatique par la technique de digestion artificielle suivie d'une PCR multiplex dans les cas positifs. Sur les quatre chacals ayant fait l'objet d'une recherche de parasites, des œufs d'ankylostomes ont été détectés chez un animal, des vers adultes et des œufs d'Echinococcus multilocularis étaient présents chez un autre animal, et aucun parasite n'a été trouvé dans un autre cas. Chez le dernier cas, des œufs d'E. multilocularis ainsi que des œufs de Toxocara canis et des sporocystes de Sarcocystis sp. ont été détectés dans le contenu intestinal, et des larves de Trichinella britovi ont été trouvées dans les échantillons de muscle. Le programme de surveillance sanitaire mis en place pour les carnivores protégés en Suisse a donc permis d'ajouter le chacal doré à la liste des hôtes des parasites zoonotiques endémiques E. multilocularis et T. britovi. Les chasseurs, agriculteurs et autres personnes susceptibles d'entrer en contact avec le chacal doré doivent être conscients du risque sanitaire associé et manipuler les fèces et les carcasses avec précaution.

Guidelines of the French Society of Otorhinolaryngology-Head and Neck Surgery (SFORL) and the French Society of Audiology (SFA) for Speech-in-Noise Testing in Adults.

OBJECTIVES: This document presents the fundamentals of speech audiometry in noise, general requirements for implementation and criteria for choice among the tests available in French according to the health-professional's needs. MATERIAL AND METHODS: The recommendations are based on a systematic analysis of the literature carried out by a multidisciplinary group of doctors, audiologists and audioprosthetists from all over France. They are graded A, B, C or expert opinion according to decreasing level of scientific evidence. RESULTS: Eight tests of speech audiometry in noise can be used in France. CONCLUSION: To be complete, evaluation of hearing status requires testing understanding of speech in noise. The examination must begin with a minimum of two measurements familiarizing the subject with the test procedure. For initial diagnosis, adaptive procedures establishing the 50% speech reception threshold (SRT50) in noise are to be preferred in order to obtain a rapid and standardized measurement of perception of speech in noise. When the aim is to measure real-life speech comprehension, tests based on sentences, cocktail-party noise and free-field stimulation are to be preferred. Prosthetic gain is evaluated exclusively in free field. This is the only way to evaluate the contribution of binaurality and to measure perception in noise in an environment as close as possible to real life. In order to avoid acoustic interference in free field, at least five loudspeakers should be used, in particular for evaluating the effectiveness of directional microphones, CROS devices enabling sounds picked up in the damaged ear to be rerouted to the functional ear, or bimodal fitting (i.e., when hearing is enabled by two modalities: for example, hearing aid for one ear, cochlear implant for the other).

Rehabilitation of telephone communication in cochlear-implanted adults.

OBJECTIVES: Telephone use correlates with quality of life, and is one of the most important expectations of cochlear implant candidates. The aim of the present study was to assess the benefit of a progressive intensive 18-session training program, conducted by telephone in cochlear implant recipients. MATERIAL AND METHODS: Nine cochlear-implanted adults underwent telerehabilitation focused on telephone use, with before-and-after assessment of: auditory performance, on Lafon monosyllabic words and MBAA sentences in quiet, cocktail-party noise and by phone; telephone use, on ad-hoc surveys and number of calls per week; and quality of life on ERSA and APHAB questionnaires. RESULTS: Before training, monosyllabic word comprehension was poorer by telephone than by direct voice (64±5.7% vs. 26±5.3%; P<0.05). After the 6-week training, there was improvement in the "note taking" telephone message task (85.0±3.7 vs. 50.0±9.0 out of 100; P<0.001), daily phone use (57.0±4.3 vs. 29±5.4 out of 100; P<0.0001), and number of calls in the week before assessment (0.0±0.0 vs. 11.0±3.0; P<0.0001). CONCLUSIONS: A progressive intensive training program by telephone improved phone use in the daily life of cochlear-implanted adults.

Guidelines (short version) of the French Society of Otorhinolaryngology (SFORL) on pediatric cochlear implant indications.

OBJECTIVES: The authors present the guidelines of the French Society of Otorhinolaryngology - Head and Neck Surgery (Société française d'oto-rhino-laryngologie et de chirurgie de la face et du cou - SFORL) on the indications for cochlear implantation in children. METHODS: A multidisciplinary work group was entrusted with a review of the scientific literature on the above topic. Guidelines were drawn up, based on the articles retrieved and the group members' individual experience. They were then read over by an editorial group independent of the work group. The guidelines were graded as A, B, C or expert opinion, by decreasing level of evidence. RESULTS: The SFORL recommends that children with bilateral severe/profound hearing loss be offered bilateral cochlear implantation, with surgery before 12months of age. In sequential bilateral cochlear implantation in children with severe/profound hearing loss, it is recommended to reduce the interval between the two implants, preferably to less than 18months. The SFORL recommends encouraging children with unilateral cochlear implants to wear contralateral hearing aids when residual hearing is present, and recommends assessing perception with hearing-in-noise tests. It is recommended that the surgical technique should try to preserve the residual functional structures of the inner ear as much as possible.

French Society of ENT (SFORL) guidelines. Indications for cochlear implantation in adults.

The authors present the guidelines of the French Society of ENT and Head and Neck Surgery (SFORL) regarding indications for cochlear implantation in adults. After a literature review by a multidisciplinary workgroup, guidelines were drawn up based on retrieved articles and group-members' experience, then read over by an independent reading group to edit the final version. Guidelines were graded A, B, C or "expert opinion" according to decreasing level of evidence. There is no upper age limit to cochlear implantation in the absence of proven dementia and if autonomy is at least partial. Bilateral implantation may be proposed if unilateral implantation fails to provide sufficiently good spatial localization, speech perception in noise and quality of life, and should be preceded by binaural hearing assessment. Rehabilitation by acoustic and electrical stimulation may be proposed when low-frequency hearing persists. Quality of life should be assessed before and after implantation.

Evaluation of the impact of hearing loss in adults: Validation of a quality of life questionnaire.

OBJECTIVES: The impact of hearing loss and of auditory rehabilitation (hearing aid, cochlear implant) on quality of life is a crucial issue. Commonly used questionnaires to assess quality of life in these patients (Nijmegen, APHAB, GBI) are time-consuming, difficult for patients to fill out, and show poor sensitivity to small improvements or deterioration. The objective of the present study was to validate a dedicated quality of life scale for hearing-impaired adults with or without auditory rehabilitation. MATERIAL AND METHODS: ERSA (Évaluation du Retentissement de la Surdité chez l'Adulte: Evaluation of the Impact of Hearing Loss in Adults) is a self-administered questionnaire. It is divided into 4 domains, each comprising 5 questions graded from 1 to 10. The questions are simple, and formulated so patients will answer according to how they feel at the actual time of the session. Test-retest reliability was measured in 38 patients. Internal coherence and validity against the APHAB questionnaire as gold standard and in relation to hearing performance were measured in 122 patients at auditory assessment. Sensitivity to change in hearing was measured in 36 cochlear implant patients, before and 6 or 12 months after implantation. RESULTS: Test-retest reliability was very satisfactory (ρ=0.88). Internal coherence was good for all questions. External validity, comparing ERSA to APHAB scores in the same non-implanted hearing-impaired patients, was good (ρ=0.52). Additionally, ERSA scores correlated with hearing performance in adverse conditions (monosyllabic words: ρ=0.22; sentences in noise: ρ=0.19). In patients tested before and after cochlear implantation, improvement in hearing performance in silence and in noise correlated with an improvement in ERSA score (ρ=0.37 to 0.59, depending on the test), but not to GBI score. CONCLUSION: The ERSA questionnaire is easy and quick to use, reliable, and sensitive to change in hearing performance after cochlear implantation.

[A report of three cases and review of auditory brainstem implants in children]. / Implantation auditive du tronc cérébral chez l'enfant. À propos de trois cas.

AIM OF THE STUDY: To present three pediatric cases of auditory brainstem implantation (ABI) and review literature data concerning this topic. PATIENTS: The first two children had a neurofibromatosis type II with bilateral sensorineural deafness; in both cases, the implant was inserted during the surgical removal of a vestibular schwannoma; the third patient had profound deafness due to bilateral cochlear nerve insufficiency associated with inner ear malformation. RESULTS: Two postoperative complications were observed: patient 1 had a persistent fever which required the replacement of the fat graft used to seal the translabyrinthine approach; patient 3 had a CSF leakage requiring additional surgery and lumbar external drainage. In our three patients, the numbers of active electrodes were 6/22 (Cochlear ABI 24M ABI), 11/12 (Medel Opus II ABI) and 11/12 (implant Medel), respectively. Due to additional major surgical procedures and to disappointing functional results of the ABI, patient 1 stopped wearing her implant 18 months after implantation. Nine months after surgery, patient 2 achieved open-set speech recognition and was very satisfied with the implant. Six months after implantation, patient 3 (cochlear nerve deficiency), who was 3.5 years-old at the time, clearly reacted to some environmental sounds but was not yet able to achieve speech recognition. CONCLUSIONS: ABI has now entered the list of treatments that can be proposed in pediatric profound sensorineural deafness. Its major risks of complications are CSF leakage and non-auditory side effects. Its outcomes are worse and less predictable than cochlear implants. Thus, its indications must remain restricted to cases meeting the following conditions: absence of alternative option to restore hearing, patients and parents high level of motivation and realistic expectations.

[Understanding the use of self-evaluation questionnaires when assessing a patient's swallowing capacity and performing follow-up activities]. / Intérêt des echelles d'autoévaluation dans le bilan et le suivi des troubles de la déglutition.

The purpose of this study was to examine the possibility of improving the assessment protocol of dysphagia and show the interest of adding a self-assessment evaluation scale to the traditional functional assessment of the swallowing process. We have a comparison of the assessment of 30 dysphagic patients with two different scales (DHI and EAT-10). Results show that the self-evaluation scales selected led to quantitative data comparable to the objective results of the COLP-FR-G functional assessment tool. We may therefore conclude that the patients' own feelings do not differ from the results of the clinical dysphagia severity assessment. Results also highlight that both scales provide similar information in terms of content and also reflect the evolution of objective data. The EAT-10 scale, by its simplicity and limited number of questions, could be proposed as a screening test in neurological patients and geriatric population, where the DHI scale, with its three subdomains (physical, functional and emotional), would be a complementary tool for the functional swallowing evaluation. Indeed, in order to evaluate dysphagia, the association of DHI, EAT-10 and COLP-FR-G offers several advantages. This protocol is convenient and rapid to administrate, it takes the diversity of etiologies into account and its score is easy to transmit to the patients' medical practitioners. Consequently, its use in the assessment of swallowing functions should be encouraged as a consistent part of the clinical practice.

Video analysis software increases the interrater reliability of video gait assessments in children with cerebral palsy.

The aim of this study was to determine the effect of using video analysis software on the interrater reliability of visual assessments of gait videos in children with cerebral palsy. Two clinicians viewed the same random selection of 20 sagittal and frontal video recordings of 12 children with cerebral palsy routinely acquired during outpatient rehabilitation clinics. Both observers rated these videos in a random sequence for each lower limb using the Observational Gait Scale, once with standard video software and another with video analysis software (Dartfish(®)) which can perform angle and timing measurements. The video analysis software improved interrater agreement, measured by weighted Cohen's kappas, for the total score (κ 0.778→0.809) and all of the items that required angle and/or timing measurements (knee position mid-stance κ 0.344→0.591; hindfoot position mid-stance κ 0.160→0.346; foot contact mid-stance κ 0.700→0.854; timing of heel rise κ 0.769→0.835). The use of video analysis software is an efficient approach to improve the reliability of visual video assessments.

[Quality of life before and after thyroplasty for vocal fold paralysis]. / Qualité de vie avant et après thyroplastie pour paralysie laryngée unilatérale.

OBJECTIVES: The aim of our prospective study was to evaluate the vocal handicap in relation with the quality of life in patients with unilateral vocal fold paralysis (UVFP), before and after thyroplasty with Montgomery implant (type I). METHODS: Ten patients had to file the VHI questioner before and three months after thyroplasty. The 30 items of the Voice Handicap Index scale are sub-divided in 3 categories referring to "Functional", "Physical" and "Emotional" dimensions. RESULTS: Before thyroplasty, the global score and the 3 sub-scales rating are high reflecting severe impairment in speech communication (VHI total = 65,9/120, F = 25.7/40, E = 19.9/40, P = 20.8/40). Three months after thyroplasty, a significant improvement is found predominantly in the field of functional and emotional evaluation, corresponding to an improved quality of social life (VHI total = 20,9/120, F = 6.3/40, E = 3.6/40, P = 10.6/40). CONCLUSION: These results show the interest in using the autoevaluation VHI scale as a complementary evaluation associated to perceptual, acoustic and aerodynamic evaluation to objectify the functional improvement in voice quality after thyroplasty.
