Patient navigation for colorectal cancer screening in deprived areas: the COLONAV cluster randomized controlled trial.

BACKGROUND: The objective of this study was to assess the effectiveness of a Patient Navigation Intervention targeting deprived patients for Colo-Rectal Cancer (CRC) screening participation. METHODS: A cluster randomized controlled trial was conducted in 5 districts. Peer Lay Patient Navigators were recruited to operate in deprived areas. Eligible participants had to be between 50 and 74 years old, live in these deprived areas and receive an invitation to the nationally organized Colo-Rectal Cancer (CRC) screening during the study period. The theory-driven navigation intervention was deployed for 18 months. A population Health Intervention Research assessment method was used to assess effectiveness and context interaction. The primary criterion was screening participation at 12 months. RESULTS: Twenty-four thousand two hundred eighty-one individuals were included inside 40 clusters. The increase in participation in the intervention group was estimated at 23%, (ORa = 1.23, CI95% [1.07-1.41], p = 0.003). For the subgroup of individuals who participated, the time delay to participating was reduced by 26% (ORa = 0.74, CI95% [0.57-0.96], p = 0.021). Main factors modulating the effect of the intervention were: closeness of navigator profiles to the targeted population, navigators' abilities to adapt their modus operandi, and facilitating attachment structure. CONCLUSION: The ColoNav Intervention succeeded in demonstrating its effectiveness, for CRC screening. Patient Navigation should be disseminate with broader health promotion goals in order to achieve equity in health care. TRIAL REGISTRATION: clinicaltrials.gov NCT02369757 24/02/2015.

[French version of The Ottawa Statement on the Ethical Design and Conduct of Cluster Randomized Trials, in a French law context]. / Version française des recommandations de la déclaration d'Ottawa sur la conception et la conduite éthique d'essais randomisés en clusters, dans le contexte législatif français.

INTRODUCTION: There is growing evidence on the ethical challenges raised by cluster randomized trials. This specificity is not reflected in the legal texts regulating research, which creates difficulties for researchers implementing these experimental designs. The Ottawa Statement (Weijer et al. 2012) aims to provide detailed guidance on the ethical design, conduct and assessment of cluster trials. More broadly aims to help research stakeholders and decision-makers to make informed ethical decisions regarding the particularity of these experimental designs. It seems that this international statement, written in English, is not sufficiently accessible to all of the French professionals involved in health research. The aim of this article is to provide these professionals with a contextualized and illustrated French translation of the "Ottawa statement". METHOD: . The "complex design" working group of the RECaP network (Research in Clinical Epidemiology and Public Health), carried out this work. A first version was discussed by the authors in several meetings. It was completed by contextual explanations and examples of French studies currently conducted by the authors. The final version was obtained by consensus and validated by the group. RESULTS: . This work reports 15 recommendations grouped into 7 key questions: How to justify cluster design? How to submit an article to an ethics committee? How to identify research participants? How and when to obtain informed consent? Who are the gatekeepers? How to assess benefits and harm? How to protect vulnerable participants? Each of these recommendations is specific to cluster trials. The recommendations are explained and detailed through concrete examples. CONCLUSION: Without interfering with current French laws, this work provides a framework for the organization, conduct and ethical assessment of cluster randomized trials in France. In the present-day context, it is essential that all concerned groups can base their decisions on recommendations in line with the elementary principles of health research ethics.

Increased intracellular survival of Salmonella Typhimurium ST313 in HIV-1-infected primary human macrophages is not associated with Salmonella hijacking the HIV compartment.

BACKGROUND: Non-typhoidal Salmonella (NTS) causes a severe invasive syndrome (iNTS disease) described in HIV-positive adults. The impact of HIV-1 on Salmonella pathogenesis and the molecular basis for the differences between these bacteria and classical diarrhoeal S. Typhimurium remains unclear. RESULTS: Here, we show that iNTS-associated S. Typhimurium Sequence Type 313 (ST313) bacteria show greater intracellular survival in primary human macrophages, compared with a 'classical' diarrhoeal S. Typhimurium ST19 isolate. The increased intracellular survival phenotype of ST313 is more pronounced in HIV-infected macrophages. We explored the possibility that the bacteria take advantage of the HIV-associated viral-containing compartments created in human macrophages that have low pH. Confocal fluorescence microscopy and focussed ion beam-scanning electron microscopy tomography showed that Salmonella did not co-localise extensively with HIV-positive compartments. CONCLUSION: The capacity of ST313 bacteria to survive better than ST19 bacteria within primary human macrophages is enhanced in cells pre-infected with HIV-1. Our results indicate that the ST313 bacteria do not directly benefit from the niche created by the virus in HIV-1-infected macrophages, and that they might take advantage from a more globally modified host cell. SIGNIFICANCE: A better understanding of the interplay between HIV-1 and Salmonella is important not only for these bacteria but also for other opportunistic pathogens.

Autologous bilayered self-assembled skin substitutes (SASSs) as permanent grafts: a case series of 14 severely burned patients indicating clinical effectiveness.

Split-thickness skin autografts (AGs) are the standard surgical treatment for severe burn injuries. However, the treatment of patients with substantial skin loss is limited by the availability of donor sites for skin harvesting. As an alternative to skin autografts, our research group developed autologous self-assembled skin substitutes (SASSs), allowing the replacement of both dermis and epidermis in a single surgical procedure. The aim of the study was to assess the clinical outcome of the SASSs as a permanent coverage for full-thickness burn wounds. Patients were recruited through the Health Canada's Special Access Program. SASSs were grafted on debrided full-thickness wounds according to similar protocols used for AGs. The graft-take and the persistence of the SASS epithelium over time were evaluated. 14 patients received surgical care with SASSs. The mean percentage of the SASS graft-take was 98 % (standard deviation = 5) at 5 to 7 d after surgery. SASS integrity persisted over time (average follow-up time: 3.2 years), without noticeable deficiency in epidermal regeneration. Assessment of scar quality (skin elasticity, erythema, thickness) was performed on a subset of patients. Non-homogeneous pigmentation was noticed in several patients. These results indicated that the SASS allowed the successful coverage of full-thickness burns given its high graft-take, aesthetic outcome equivalent to autografting and the promotion of long-term tissue regeneration. When skin donor sites are in short supply, SASSs could be a valuable alternative to treat patients with full-thickness burns covering more than 50 % of their total body surface area.

[Well-being in adulthood of patients with chronic conditions in childhood: The GEDEPAC-2 questionnaire]. / Bien-être à l'âge adulte des enfants atteints de maladies chroniques : le questionnaire GEDEPAC-2.

BACKGROUND: In France, chronic diseases affect 3 million children. In children with chronic conditions, long-term somatic outcome has been well described, but little is known about the psychosocial aspects of well-being. METHODS: Our aim was to build a self-administered questionnaire of global well-being in adults who had a chronic disease since or during childhood using a multidimensional and nonspecific approach. The questionnaire was constructed by a multidisciplinary group (epidemiologists, clinicians, sociologist, statistician). Items were built in compliance with reference data from the French general population (national surveys, free access) to allow comparative analysis adjusted for age and sex (and eventually other confounding factors) by indirect standardization (qualitative variables) or Z-scores (quantitative variables). RESULTS: The GEDEPAC-2 includes 108 items exploring 11 domains: education, employment, housing, material security, social links, civic engagement, leisure, environment, physical health/risky behavior, health-related quality of life and sex life. Factual questions and satisfaction scales jointly explore social well-being. Quality of life is analyzed in terms of physical quality of life, mental quality of life, fatigue and burden of treatment by 3 questionnaires validated in French (SF-12; MFI-20; Burden of Treatment Questionnaire). Experience of transition from pediatric to adult healthcare is described in 21 items. Paper and electronic versions were developed. CONCLUSION: Built in a multidimensional approach to well-being and in line with the available reference data, GEDEPAC-2 will facilitate the implementation of future studies on impact in adulthood of chronic disease in childhood.

Are dietary reports in a case-control study on thyroid cancer biased by risk perception of Chernobyl fallout?

BACKGROUND: In retrospective case-control studies performed following nuclear tests or nuclear accidents, individual thyroid radiation dose reconstructions are based on fallout and meteorological data from the residential area, demographic characteristics, and lifestyle as well as dietary information. Collecting the latter is a controversial step, as dietary declarations may be affected by the subjects' beliefs about their risk behavior. This report analyses the potential for such bias in a case-control study performed in eastern France. METHODS: The study included 765 cases of differentiated thyroid carcinoma matched with 831 controls. Risk perceptions and beliefs of cases and controls were compared using Chi2 tests and differences in dietary reports were analyzed using a two-way ANOVA. RESULTS: In general, atmospheric pollution and living near a nuclear power plant were the two major risks that may influence thyroid cancer occurrence cited by cases and controls. When focusing in particular on the consequences of the Chernobyl accident, cases were more likely to think that the consequences were responsible for thyroid cancer occurrence than controls. Vegetable consumption during the two months after the Chernobyl accident was correlated with the status of subjects, but not to their beliefs. Conversely, consumption of fresh dairy products was not correlated with the status or beliefs of subjects. CONCLUSION: We found no evidence of systematic bias in dietary reports according to the status or beliefs held by subjects about the link between thyroid cancer occurrence and Chernobyl fallout. As such, these dietary reports may be used in further studies involving individual dosimetric reconstructions.

2-µm Ho emitter-based coherent DIAL for CO(2) profiling in the atmosphere.

We report on the use of a thulium-fiber-pumped holmium-based emitter in a coherent differential absorption lidar (CDIAL) experiment for high time and space resolution of CO(2) absorption field in the atmosphere. The 2-µm high-power dual-wavelength single-mode Q-switched Ho:YLF oscillator delivers 10-mJ pulses with a duration of 40 ns at 2 kHz. Both short pulse duration and high repetition rate were chosen to increase the DIAL precision and time and space resolution in coherent detection. The CDIAL provides 150-m range and 15-min time-resolved CO(2) absorption coefficient with a calculated instrumental error of 0.5% at 500 m and less than 2% at 1 km. Dry-air CO(2) mixing ratio estimates from the DIAL system are compared with simultaneous in situ gas analyzer measurements during a 20-h-long experiment.

Validation of a French version of the Sunnybrook facial grading system.

BACKGROUND: The aim of this study was to translate the Sunnybrook Facial Grading System and its specific criteria into French and validate its use by French-speaking physicians for facial palsy evaluation. MATERIAL AND METHODS: The original English version of the Sunnybrook Facial Grading System and its specific criteria was translated into French according to international standards. Twenty videos of patients with a wide range of facial palsy in terms of duration and severity were independently rated, twice each, by 6 physicians with varied experience in facial palsy care. Internal consistency and intra- and inter-rater reliability were analyzed. RESULTS: The French version of Sunnybrook Facial Grading System and its specific criteria both showed good internal consistency, with Cronbach alpha of 0.84 and 0.86 respectively. Inter-rater reliability was excellent in both sessions for the composite score, the score of symmetry at rest and during voluntary movement and synkinesis: intraclass correlation coefficient (ICC) between 0.77 and 0.98. Intra-rater reproducibility on the composite score and subscores was also excellent and comparable for expert, experienced and novice physicians, with an average ICC of 0.95. CONCLUSION: The French version of the Sunnybrook Facial Grading System and its specific criteria is reliable, reproducible and easy to use by French-speaking teams for facial palsy evaluation.

Musical Ear Syndrome: Prevalence and characteristics in cochlear implant bearers.

INTRODUCTION: Musical Ear Syndrome (MES) is an uncommon phenomenon described as the perception of auditory musical sensations not corresponding to any external stimulus. It seems to be more frequent in case of profound hearing loss. Our objective was to evaluate prevalence, characteristics and risk factors in a population of cochlear implant patients. METHODS: A retrospective study was conducted in cochlear implant patients, who were adult (>18 years) in 2020 and underwent cochlear implantation between 1993 and 2019. We analyzed the presence and characteristics of MES. RESULTS: 118 of the 358 patients (33%) perceived or had perceived auditory musical sensations: 71 (19.8%) before, 100 (28%) after, and 53 (14.8%) both before and after implantation. The musical auditory sensations were usually short and well-tolerated, resembling instrumental music, and occurring several times a day. Thirteen patients (11%) considered them intolerable. Fatigue was a triggering factor in 40 patients (33.9%). Personal and medical characteristics, type of implantation, make of implant, etiology and tinnitus did not emerge as risk factors. On the other hand, MES+ patients were significatively younger (56±17.4 years versus 61.9±17.9 years; P=0.0009). Despite the phenomenon, patients were satisfied with implant functioning and subjective auditory performance was not affected. CONCLUSION: Prevalence of Musical Ear Syndrome was high in cochlear implant patients, and especially in younger subjects. It is essential to improve knowledge of this phenomenon.

The influence of acute exercise on bone biomarkers: protocol for a systematic review with meta-analysis.

BACKGROUND: Bone is a plastic tissue that is responsive to its physical environment. As a result, exercise interventions represent a potential means to influence the bone. However, little is currently known about how various exercise and participant characteristics interact to influence bone metabolism. Acute, controlled, interventions provide an in vivo model through which the acute bone response to exercise can be investigated, typically by monitoring circulating bone biomarkers. Currently, substantial heterogeneity in factors such as study design, quality, exercise, and participant characteristics render it difficult to synthesize and evaluate the available evidence. Using a systematic review and meta-analytic approach, the aim of this investigation is to quantify the effect of an acute exercise bout on circulating bone biomarkers as well as examine the potential factors that may moderate this response, e.g., variation in participant, exercise, and sampling characteristics. METHODS: This protocol was designed in accordance with the PRISMA-P guidelines. Seven databases (MEDLINE, Embase, Sport Discus, Cochrane CENTRAL, PEDro, LILACS, and Ibec) will be systematically searched and supplemented by a secondary screening of the reference lists of all included articles. The PICOS (Population, Intervention, Comparator, Outcomes and Study Design) approach was used to guide the determination of the eligibility criteria. Participants of any age, sex, training, or health status will be considered for inclusion. We will select studies that have measured the bone biomarker response before and after an acute exercise session. All biomarkers considered to represent the bone metabolism will be considered for inclusion, and sensitivity analyses will be conducted using reference biomarkers for the measurement of bone resorption and formation (namely ß-CTX-1 and P1NP). Multi-level, meta-regression models within a Bayesian framework will be used to explore the main effect of acute exercise on bone biomarkers as well as potential moderating factors. The risk of bias for each individual study will be evaluated using a modified version of the Downs and Black checklist while certainty in resultant outcomes will be assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. DISCUSSION: A better understanding of the bone metabolic response to an acute bout of exercise has the potential to advance our understanding of the mechanisms through which this stimulus impacts bone metabolism, including factors that may moderate this response. Additionally, we will identify current gaps in the evidence base and provide recommendations to inform future research. SYSTEMATIC REVIEW REGISTRATION: This protocol was prospectively registered in the Open Science Framework Registry ( https://osf.io/6f8dz ).

Bone mass and microarchitecture of irradiated and bone marrow-transplanted mice: influences of the donor strain.

UNLABELLED: Total body irradiation and bone marrow transplantation induced dramatic trabecular bone loss and cortical thickening in mice. Transplanted cells were engrafted in bone marrow, along trabeculae, and in periosteal and endosteal envelopes. None of the osteocytes were of donor origin. Bone microarchitecture of transplanted mice changed to tend toward the donor phenotype. INTRODUCTION: Osteopenia and osteoporosis are complications of bone marrow transplants (BMT) attributed to related chemotherapy. However, the specific influence of total body irradiation (TBI) is unknown. METHODS: We investigated the effects of TBI and BMT on bone mass and microarchitecture by micro-CT. Eighteen C57Bl/6 (B6) mice receiving lethal TBI had a BMT with marrow cells from green fluorescent protein--transgenic-C57Bl/6 (GFP) mice. Transplanted (T(GFP)B6), B6, and GFP mice were euthanized 1, 3, and 6 months after BMT or at a related age. RESULTS: T(GFP)B6 presented a dramatic bone loss compared with B6 and did not restore their trabecular bone mass over time, despite a cortical thickening 6 months after BMT. Serum testosterone levels were not significantly reduced after BMT. During aging, GFP mice have less trabeculae, thicker cortices, but a narrower femoral shaft than B6 mice. From 3 months after BMT, cortical characteristics of T(GFP)B6 mice differed statistically from B6 mice and were identical to those of GFP mice. GFP(+) cells were located along trabecular surfaces and in periosteal and endosteal envelopes, but none of the osteocytes expressed GFP. CONCLUSION: Our findings suggest that engrafted cells did not restore the irradiation-induced trabecular bone loss, but reconstituted a marrow microenvironment and bone remodeling similar to those of the donor. The effects of irradiation and graft on bone remodeling differed between cortical and trabecular bone.

[Pelvic and spinal MR follow-up of multiple myeloma patients after high-dose chemotherapy and autologous peripheral blood stem cell transplant]. / Suivi par IRM pelvi-rachidienne d'une cohorte de patients atteints de myélome multiple, traités par chimiothérapie à haute dose et autogreffe de cellules souches périphériques.

PURPOSE: To evaluate the changes of bone marrow lesions on pelvic and spinal MR in patients with multiple myeloma after high-dose chemotherapy and autologous peripheral blood stem cell transplant. PATIENTS AND METHODS: Pelvic and spinal MR examinations were obtained at presentation (myeloma diagnosis) and 1 year after transplant in 20 patients that were part of a group of 39 patients enrolled in a prospective study. The type of marrow replacement (classified in stages with stage 0: normal; stage 1: salt and pepper; stage 2: focal infiltration; stage 3: diffuse infiltration), the number and size of marrow lesions and the number of vertebral compression fractures were recorded. We have compared the findings prior to and following transplant, with correlation to the response to treatment and the use of biphosphonates. RESULTS: The type of marrow replacement was improved following transplant in 65% of patients (not statistically significant). The number and size of nodules > 20 mm showed significant reduction (p = 0.0224 and p = 0.0237 respectively). Lesions on MR improved in 50% of patients with good response and 75% of patients with poor response to treatment. Patients receiving biphosphonates showed more vertebral compression fractures. CONCLUSION: The evolution of marrow replacing lesions on MR is discordant compared to the biological and clinical response to treatment. Pelvic and spinal MR evaluation at the time of diagnosis does not appear to be a good predictive factor of response to treatment. Biphosphonates do not appear to prevent new vertebral compression fractures. Pelvic and spinal MR provides interesting data in the follow-up of patients with myeloma following autologous transplant, especially in the local evolution of marrow replacing lesions, but our results do not justify its use in routine clinical practice.

Patients' association programs for adolescents and young adults: The JAP study.

INTRODUCTION: A dozen innovative care clinics have recently opened in France to support the transition of adolescents with chronic conditions between pediatric and adult healthcare units through various interventions. Some patients' associations have set up specific programs for adolescents and young adults (AYAs) in order to facilitate the transition process, but they are not well-known among healthcare professionals. Our aim was to describe these programs and to evaluate the quality of their implementation and transferability into transition clinics. MATERIEL AND METHODS: We conducted semistructured interviews with representatives of associations that proposed interventions dedicated to AYAs with chronic conditions. We collected quantitative and qualitative data to describe these interventions. Descriptive statistics were run on quantitative data and a thematic analysis of the qualitative data was made. RESULTS: A questionnaire was sent to 55 associations, 19 (36%) of them had established programs and were contacted; interviews were conducted with 16 of them. Thirteen were national associations, 11 focused on a specific chronic disease, three supported multiple chronic conditions, and two were available to any AYA with chronic disease. Programs were mainly camps (n=5; from 2days to 3weeks) and workshops (n=5). Educational considerations and hobbies were more frequently discussed when peers were directly involved in the program. Stakeholders were mainly other patients and peers (9/16). Fourteen out of 16 were perceived as successful (perceived improvement in AYA quality of life and/or positive feedback). Twelve out of 16 associations thought that their program could be transferable to transition clinics and all were interested in collaboration. DISCUSSION: This work highlights five key points to be considered in the clinical care setting before building programs: unique tailoring and customization, complementarity with existing programs in patients' associations, viability based on peer involvement and evaluation, a common main goal, and using transition clinics' assets to direct AYAs towards the most suitable program.

A subset of fibromyalgia patients have findings suggestive of chronic inflammatory demyelinating polyneuropathy and appear to respond to IVIg.

OBJECTIVES: The aetiopathogenesis of the fibromyalgia syndrome (FMS) remains unknown. Recent reports, however, suggest that a subgroup of FMS subjects has an immune-mediated disease. Therefore, our primary objective was to study FMS subjects for evidence of an immune-mediated demyelinating polyneuropathy. Our secondary objective was to determine the effects of treating these FMS subjects with the immune modulator, intravenous immunoglobulin (IVIg). METHODS: Fifty-eight FMS subjects, 26 rheumatic non-FMS subjects and 52 non-rheumatic non-FMS subjects were studied. Subjective measures of paraesthesias, weakness, stocking hypaesthesia, pain, fatigue and stiffness were made. Objective measures of tenderness, proximal muscle strength and electrodiagnostic (EDX) evidence of polyneuropathy and demyelination were also made. Eleven other FMS subjects underwent sural nerve biopsy. RESULTS: Paraesthesias, subjective weakness and stocking hypaesthesia were more common in FMS than in rheumatic non-FMS (P < or = 0.0001). Proximal muscle strength was less in FMS than in rheumatic non-FMS (P < or = 0.0001). EDX demonstrated a distal demyelinating polyneuropathy, suggestive of chronic inflammatory demyelinating polyneuropathy (CIDP), in 33% of FMS subjects. No rheumatic non-FMS subject had polyneuropathy (P = 0.005), or demyelination (P = 0.05). Fifteen FMS/CIDP subjects were subsequently treated with IVIg (400 mg/kg each day for 5 days). Pain (P = 0.01), tenderness (P = 0.001) and strength (P = 0.04) improved significantly. Fatigue and stiffness trended towards improvement. CONCLUSIONS: A significant subset of FMS subjects have clinical and EDX findings suggestive of CIDP. IVIg treatment shows promise in treating this subset. These observations have implications for better understanding and treating some FMS patients.

[Pregnancy and psychoactives substances: prevalence study based on the declared consumption]. / Grossesse et substances psychoactives: étude de prévalence de la consommation déclarée.

OBJECTIVES: Evaluate substance use (tobacco, alcohol, psychotropic drugs, illicit drugs) declared before and during pregnancy. PATIENTS AND METHODS: Two hundred and forty-five pregnant women were interviewed through a self-administered and anonymous questionnaire as they were going to a prenatal consultation in a maternity hospital in the Parisian area. RESULTS: Before pregnancy, 16.3% of women reported smoking and 10.2% carried on smoking during pregnancy. Altogether, 40.8% of women reported alcohol consumption before pregnancy; 25.3% of women had contact with alcohol during pregnancy; 4.5% reported tobacco and alcohol consumption during pregnancy. During the month preceding the study, the consumption of psychotropic drugs (hypnotics, antidepressants or sedatives) was reported by 3.7% of women and that of marijuana by 2.4%. Moreover, the marijuana consumers, who tend to drink alcohol more often, combine important social and familial difficulties and represent a high-risk group. CONCLUSION: Tobacco and alcohol use in this study were lower than in any previously conducted French surveys. Methodological specificities and cultural factors might explain those results. However, this is the first study that asses substance use and marijuana use, in particular, by French pregnant women.

[Prediction of successful induction of labor: a comparison between fetal fibronectin assay and the Bishop score]. / Prédiction de la réussite du déclenchement du travail. Comparaison entre le score de Bishop et le dosage de la fibronectine foetale.

OBJECTIVE: The aim of our study is to determine whether the fetal fibronectin is a better predictor of successful induction of labor than the Bishop score. MATERIAL AND METHODS: A prospective observational non-randomized study was conducted in our unit including 234 patients scheduled for induction of labor from October 2000 to June 2004. Fetal fibronectin was assayed by taking sample from the endocervix and the cervical status was evaluated using the Bishop score. Data were analysed by Chi-square test of Mantel-Haenzel and Cox stepwise multiple regression using SPSS version 12 software. RESULTS: The likelihood ratios for predicting that vaginal delivery would occur within 24h of induction for positive fetal fibronectine were 1.34 (95% CI 1.04-1.73, p=0.027) all patients included and 1.51(95% CI 1.00-2.33, p=0.048) for the nulliparas and 1.92 (95% CI 1.51-2.42, p=0.0001) for the Bishop score. On multiple regressions, the only variables independently associated with a successful induction were the Bishop score, the parity and the age of the patient. No significant association was found between the presence of cervical fibronectin and the caesarean section rate: 21.84% for positive fibronectin versus 21.78% for negative fibronectin. CONCLUSION: The fetal fibronectine is probably useless in this context, given the additional cost and no improvement compared with the simple Bishop score.

Cochlear implantation in far-advanced otosclerosis: hearing results and complications.

Severe forms of otosclerosis known as far-advanced otosclerosis (FAO) can lead to severe to profound sensorineural hearing loss and can justify cochlear implantation. Because of the pathophysiology of otosclerosis, patients implanted for FAO may experience an increased rate of complications, such as facial nerve stimulation or electrode dislocation, and may have poorer hearing outcomes than expected. This retrospective study aimed to compare cochlear implantation hearing outcomes, surgical difficulties and complications in FAO patients versus non-FAO patients. Moreover, we evaluated whether high resolution computed tomography (CT scan) findings were predictive of perioperative problems, complications and hearing outcomes. FAO patients were diagnosed based on medical history, examination and CT scan. Thirty-five ears from FAO patients were compared to 38 control ears. Audiometric results were assessed at least 12 months after implantation by pure tone average, speech reception threshold, monosyllabic and disyllabic word recognition score (WRS) and Central Institute for the Deaf (CID) sentences test. Complications and surgical difficulties were compiled. CT scan findings were categorised within 3 grades of otosclerotic extension. No significant difference was found between FAO and non-FAO hearing outcomes, except that monosyllabic WRS were lower for FAO patients, especially those who underwent previous stapedotomy. Facial nerve symptomatology occurred in 8.6% of FAO patients; among these, one required explantation-reimplantation surgery. 86% of FAO implanted patients had retrofenestral extension on CT. These were associated with poorer disyllabic WRS (51% vs 68%, p < 0.05) than those with only fenestral involvement. Although not significant, high grade of severity on CT tended to be associated with surgical difficulties and complications. Cochlear implantation in FAO patients is an effective treatment technique. Though the overall complication rate is low, it tends to be higher in cases of severe extension on CT. Patient counselling should be adjusted accordingly.

The Development and Initial Validation of the Child Perceived Discrimination Questionnaire.

Perceived discrimination can affect psychological and physical health, starting in childhood. Yet, the measures that exist for measuring perceived discrimination among children have methodological limitations and structural/theoretical inconsistencies. The Child Perceived Discrimination Questionnaire (CPDQ) fills the gaps of the current measures by assessing two dimensions of everyday discrimination from both child and adult sources. To assess the reliability and validity of the CPDQ, we examined data from 163 participants, aged 9-11, 52.15% female, 57.67% Black. Results indicated that the CPDQ has good to excellent internal consistency and provided preliminary support for an a priori hypothesized factor structure. The CPDQ also discriminated between different race groups and demonstrated construct validity. Future research should seek additional evidence of reliability and validity for the CPDQ, though this preliminary evidence suggests that the CPDQ is appropriate for assessing perceived discrimination in children.
