Cochlear implantation in elderly: indication and results

The aim of the study was to investigate the outcome of CI among elderly cochlear implant recipients. Results from our study have shown that elder patient implanted above 75 yrs can obtain significant hearing benefit from cochlear implantation. Similarly to the results reported by Vermeer1, in our study subjects implanted at elder age show lower scores compared to younger adult implantees

CAPTURAS DE LANGOSTA VERDE (Panulirus gracilis) EN LA ZONA ESPECIAL DE MANEJO MARINO COSTERO ARCHIPIÉLAGO DE LAS PERLAS EN PANAMÁ

In 2007, a closure of the Pacific green lobster fishery established in Las Perlas Archipelago, this occurs every year from December 1 to April 15. However, the impact this ban has had is unknown. This study reports baseline information. The catch (kg) of lobster tail per diver per fishing trip calculated at 1.3 kg. Twenty five percent of lobster tails do not reach 12 cm (legal minimum size) and smaller abdominal sizes were recorded for males and females to those reported for Las Perlas 8 years ago. 96 metric tons estimated as the total catch for the 2014 season.En el 2007, se estableció en el Archipiélago de Las Perlas, el cierre de la temporada de pesca de langosta verde del 1 de diciembre al 15 de abril de cada año. Hasta el momento, el impacto que esta veda ha tenido, es desconocido. Este estudio reporta información de línea base actualizada sobre la captura por unidad de esfuerzo (CPUE), que se calculó en 1.3 kg de cola de langosta por buzo por viaje de pesca. El 25% de las colas de langostas no alcanza los 12 cm (tamaño mínimo legal) y se estimó la captura total de la temporada abril-diciembre 2014 en 96 toneladas métricas. &nbsp

Systematic review of the literature on the clinical effectiveness of the cochlear implant procedure in adult patients

The aim of this systematic review was to summarize the results of scientific publications on the clinical effectiveness of the cochlear implant (CI) procedure in adults. The members of the Working Group first examined existing research evidence from the national and international literature and main international guidelines. They considered as universally accepted the usefulness/effectiveness of unilateral cochlear implantation in severelyprofoundly adult patients. Accordingly, they focused their attention on the systematic reviews addressing clinical effectiveness and cost/efficacy of CI procedures, with particular regard to the most controversial issues for which international consensus is still lacking. The following aspects were evaluated: monolateral CI in advanced-age adult patients; bilateral (simultaneous/sequential) CI vs. unilateral CI and vs. bimodal stimulation; benefits derived from the monolateral CI procedure in adult patients with prelingual deafness. With regard to CI in elderly patients, the selected studies document an improvement of the quality of life and perceptive abilities after CI, even if the benefits were found to be inferior in patients over 70 years at the time of surgery. Thus, from the results of the studies included in the review, advanced age is not a contraindication for the CI procedure. With respect to unilateral CI, bilateral CI offers advantages in hearing in noise, in sound localization and less during hearing in a silent environment. However, high interindividual variability is reported in terms of benefits from the second implant. With regard to CI in prelingually deaf adults, the selected studies document benefits deriving from the CI procedure in terms of improvement of perceptive abilities and in the quality of life after CI, as well as subjectively perceived benefits. However, there is high interindividual variability and the study sample is limited

Bell's palsy: Symptoms preceding and accompanying the facial paresis

This individual prospective cohort study aims to report and analyze the symptoms preceding and accompanying the facial paresis in Bell's palsy (BP). Two hundred sixty-nine patients affected by BP with a maximum delay of 48 hours from the onset were enrolled in the study. The evolution of the facial paresis expressed as House-Brackmann grade in the first 10 days and its correlation with symptoms were analyzed. At the onset, 136 patients presented postauricular pain, 114 were affected by dry eye, and 94 reported dysgeusia. Dry mouth was present in 54 patients (19.7%), facial pain, hyperlacrimation, aural fullness, and hyperacusis represented a smaller percentage of the reported symptoms. After 10 days, 39.9% of the group had a severe paresis while 10.2% reached a complete recovery. Dry mouth at the onset was correlated with severe grade of palsy and was prognostic for poor recovery in the early period. These outcomes lead to the deduction that the nervus intermedius plays an important role in the presentation of the BP and it might be responsible for most of the accompanying symptomatology of the paresis. Our findings could be of important interest to early address a BP patient to further examinations and subsequent therapy

A registry for the collection of data in cochlear implant patients

The need to optimize the use of all the information that modern technological tools have made available to the physician ENT/audiologist has increasingly emerged within the Italian scientific community. Towards this purpose, it is necessary to create a registry of the patients using cochlear implants (CIs). This registry will include a homogeneous summary of the information deriving from multiple sources related to daily clinical practice, in order to assess auditory benefits, safety and reliability in patients with cochlear implants, and organization over the national territory. The primary objectives relative to the above-mentioned analysis are to assess the impact of the use of cochlear implants on patient health, to ensure traceability of the devices currently used, monitoring their safety and reliability over time, to guarantee access of the technique in clinical and organizational conditions that can allow the best possible benefits. The aspects concerning implementation of the registry were discussed extensively during the first meetings of the Working Group (WG). In particular, owing to the complexity and high costs related mainly to the development of the technological aspects and the need to involve technological partners external to the WG, and to respect current privacy laws, the WG members decided that the project should be limited to proposal of a paper registry to be implemented at a later stage, possibly within the framework of successive research projects. During meetings, the WG members discussed various aspects of implementation of the registry, and in particular the scientific features connected to objectives, inclusion criteria, and structure of the forms needed for data collection and organizational aspects. A registry is proposed herein

Analysis of the impact of professional involvement in evidence generation for the HTA Process, subproject “Cochlear Implants”: methodology, results and recommendations

The aim of Health Technology Assessment (HTA) is to provide decision-makers, distributors and recipients with information on the effectiveness, cost and impact of health technologies. The present study constitutes a subproject within the wider project “Analysis of the impact of professional involvement in evidence generation for the HTA process”, which is part of the strategic programme “Transfer of the results of the research in clinical practice and organisation of healthcare services”, coordinated by Laziosanità – Agency of Public Healthcare of the Lazio Region and AgeNaS (National Agency for Regional Healthcare Services). The objectives of the present subproject (cochlear implants) are as follows: a) to produce a report regarding the health impact of cochlear implants (CI) on their recipients, through a systematic review of literature and extensive selection of relative studies, combining the outcomes with metanalytical techniques. Output: report on the indications of usage in the groups of population for which benefits are controversial; b) to create a registry of patients using cochlear implants. The registry should contain a selection of anagraphic and clinical information relative to patient follow-up in order to assess factors associated with safety and impact on cochlear implant users. This source of information is essential for future observational studies. This was divided into 4 phases: 1st phase: definition of key participants in the assessment process; 2nd phase: definition of methods and timing of “Aims” (definition of the objective); 3rd phase: definition of the methods and times of the “assessment process”, 4th phase: production of the final report. From the analysis of systematic reviews and italian and international guidelines, the Working Group members approved recommendations on the following topics: results after CI in children in relation to age at implantation, bilateral CI in children, CI in deaf children with associated disabilities, CI in adults with advanced age, bilateral CI in adults and CI in adults with pre-lingual deafness. These recommendations have also been evaluated by the Consulting Committee members and approved with minimal suggestions

A look at the other 90 per cent: Investigating British Sign Language vocabulary knowledge in deaf children from different language learning backgrounds

In this study we present new data on deaf children's receptive and expressive vocabulary knowledge in British Sign Language (BSL) from a sample consisting of children with deaf parents, children with hearing parents, and children with additional needs. Their performance on three BSL vocabulary tasks was compared with (previously reported findings from) a sample of deaf fluent signers. We use these data to assess the effects of some key demographic/ child variables on deaf signing children's vocabulary and discuss findings in the relation to the meaning of 'normative' data and samples for this heterogeneous population. Findings show no effect of the presence of additional disabilities on participants' scores for any of the three tasks. As expected, chronological age is the most significant factor in performance on all vocabulary tasks while the number of deaf relatives only becomes statistically significant for the form recall task. This study contributes to the field of sign language assessment by seeking to identify key variables in heterogeneity and how these variables affect signed vocabulary acquisition with the long-term objective of informing intervention

Internal Jugular Vein Cross-Sectional Area Enlargement Is Associated with Aging in Healthy Individuals.

Internal jugular vein (IJV) narrowing has been implicated in central nervous system pathologies, however normal physiological age- and gender-related IJV variance in healthy individuals (HIs) has not been adequately assessed.We assessed the relationship between IJV cross-sectional area (CSA) and aging.This study involved 193 HIs (63 males and 130 females) who received 2-dimensional magnetic resonance venography at 3T. The minimum CSA of the IJVs at cervical levels C2/C3, C4, C5/C6, and C7/T1 was obtained using a semi-automated contouring-thresholding technique. Subjects were grouped by decade. Pearson and partial correlation (controlled for cardiovascular risk factors, including hypertension, heart disease, smoking and body mass index) and analysis of variance analyses were used, with paired t-tests comparing side differences.Mean right IJV CSA ranges were: in males, 41.6 mm2 (C2/C3) to 82.0 mm2 (C7/T1); in females, 38.0 mm2 (C2/C3) to 62.3 mm2 (C7/T1), while the equivalent left side ranges were: in males, 28.0 mm2 (C2/C3) to 52.2 mm2 (C7/T1); in females, 27.2 mm2 (C2/C3) to 47.8 mm2 (C7/T1). The CSA of the right IJVs was significantly larger (p<0.001) than the left at all cervical levels. Controlling for cardiovascular risk factors, the correlation between age and IJV CSA was more robust in males than in the females for all cervical levels.In HIs age, gender, hand side and cervical location all affect IJV CSA. These findings suggest that any definition of IJV stenosis needs to account for these factors

Internal Jugular Vein Cross-Sectional Area and Cerebrospinal Fluid Pulsatility in the Aqueduct of Sylvius: A Comparative Study between Healthy Subjects and Multiple Sclerosis Patients

Objectives Constricted cerebral venous outflow has been linked with increased cerebrospinal fluid (CSF) pulsatility in the aqueduct of Sylvius in multiple sclerosis (MS) patients and healthy individuals. This study investigates the relationship between CSF pulsatility and internal jugular vein (IJV) cross-sectional area (CSA) in these two groups, something previously unknown. Methods 65 relapsing-remitting MS patients (50.8% female; mean age = 43.8 years) and 74 healthy controls (HCs) (54.1% female; mean age = 43.9 years) were investigated. CSF flow quantification was performed on cine phase-contrast MRI, while IJV-CSA was calculated using magnetic resonance venography. Statistical analysis involved correlation, and partial least squares correlation analysis (PLSCA). Results PLSCA revealed a significant difference (p<0.001; effect size = 1.072) between MS patients and HCs in the positive relationship between CSF pulsatility and IJV-CSA at C5-T1, something not detected at C2-C4. Controlling for age and cardiovascular risk factors, statistical trends were identified in HCs between: increased net positive CSF flow (NPF) and increased IJV-CSA at C5-C6 (left: r = 0.374, p = 0.016; right: r = 0.364, p = 0.019) and C4 (left: r = 0.361, p = 0.020); and increased net negative CSF flow and increased left IJV-CSA at C5-C6 (r = -0.348, p = 0.026) and C4 (r = -0.324, p = 0.039), whereas in MS patients a trend was only identified between increased NPF and increased left IJV-CSA at C5-C6 (r = 0.351, p = 0.021). Overall, correlations were weaker in MS patients (p = 0.015). Conclusions In healthy adults, increased CSF pulsatility is associated with increased IJV-CSA in the lower cervix (independent of age and cardiovascular risk factors), suggesting a biomechanical link between the two. This relationship is altered in MS patients
