Experts' discussion: implications of the World Health Organization's World report on hearing for the cochlear implant field.

Objective: This review aims to analyse the implications of the World Health Organization's 2021 world report on hearing, with a particular focus on the cochlear implant field. The objective is to understand the challenges and opportunities highlighted in the report and propose viable solutions for effective implementation within the cochlear implant community.

Methods: Following the release of the World Health Organization's world report on hearing, cochlear implant professionals explored and discussed the implications of the report with examples from various countries to understand the disparities in access, reimbursement policies, and social stigma associated with hearing loss.

Removal of organic matter from wastewater using M/Al-pillared clays (M = Fe or Mn) as coagulants.

This work is about organic matter removal from Sidi Bel Abbes wastewater plant (Algeria) by coagulation on pillared clays (PILCs) under pH and PZC (point of zero charge), conditions. Two pillared clays, M/Al-PILCs (M = Fe or Mn), were synthesized, characterized, and studied as coagulants. Results showed that Fe/Al-pillared clay exhibits superior efficiency, with 18% higher removal rate than the common coagulants alum (AS) and ferric chloride (FCl), and that sedimentation time has positive effect on turbidity removal, with 95.

Use of a mid-scala and a lateral wall electrode in children: insertion depth and hearing preservation.

Conclusions: Atraumatic insertion of the HiFocus Mid-Scala (HFMS) electrode via the round window was successfully achieved in seven children. Residual hearing 6 months post-operatively was preserved to within 10 dB HL of the pre-operative audiogram at 500 Hz for six children, indicating minimal initial insertion trauma to the cochlea.

Objectives: The objectives were to document the clinical experience and evaluate differences between HFMS and HiFocus 1j (HF1j) by means of insertion depth and hearing preservation results.

Multicentre investigation on electrically evoked compound action potential and stapedius reflex: how do these objective measures relate to implant programming parameters?

Objectives: The aims of this study were to collect data on electrically evoked compound action potential (eCAP) and electrically evoked stapedius reflex thresholds (eSRT) in HiResolution(TM) cochlear implant (CI) users, and to explore the relationships between these objective measures and behavioural measures of comfort levels (M-levels).

Methods: A prospective study on newly implanted subjects was designed. The eCAP was measured intra-operatively and at first fitting through neural response imaging (NRI), using the SoundWave(TM) fitting software.

[Prevalence of respiratory systems and evaluation of sensitization levels in traditional grain market workers in Casablanca].

Our study proposes to evaluate the prevalence of clinical respiratory symptoms, spirometric abnormalities and allergy skin test sensitivities in two groups: on exposed to grain dust in a big traditional grain market in Casablanca and the other unexposed. The inquiry which concerned 277 exposed workers and 230 non exposed consisted of a questionnaire, spirometric examinations and skin prick testings. Exposed and no exposed groups are statically similar as far as physical data (sex, age, weight, heignt) and smoking habits.

[Hygiene, working conditions and professional risks in the Moorish "hammams++" in Marrakech].

Moorish "Hammam" baths are used by almost all of the Moroccan population. We evaluated the occupational hazards associated with these baths by studying the working conditions, hygiene and safety at ten Hammam baths in Marrakech. We carried out a descriptive, cross-sectional epidemiological study of 60 workers (30 men and 30 women).

[Zygomatic-orbito-malar fractures. Apropos of 85 cases].

Our retrospective study has concerned 85 cases of zygomatic-orbito molar fractures, hospitalised and treated from january 1983 to december 1992. 86% of patients were men. The young adult is interested in 78% of cases.

[Osteoma of the frontal sinus. Apropos of 10 cases].

The authors report 10 cases of frontal sinus osteoma. The patient group consisted of 5 men and 5 women, ranging in age from 15 to 60 years. The most common revelating symptom was headache.

[Paranasal sinus mucocele].

A retrospective study of 25 sinuses mucoceles over a ten year period is presented. The authors insist on epidemics and diagnostics characteristics of this pathology and discuss the various therapeutics means.

Intravegetation antimicrobial distribution in endocarditis: a numerical model and establishment of the conditions for an in-vitro test.

Two problems appear when it is desired to get good knowledge concerning transfer of matter through a material, and especially the penetration of antibiotics into vegetations on heart valves. One is to build a numerical model to describe and simulate the process and thus to gain a fuller insight into the nature of the transfer. The other is to develop an in vitro test to represent the in vivo process, with simple operational conditions and accurate measurements.

[Nasosinusal inverted papilloma. Apropos of 6 cases].

We report in this study six cases of the inverted papillomas of the nose, that we have noticed in the ORL's department in 20 august hospital from 87 to february 1992. It's about patients aged from 12 to 60 years old, a child, a woman and four tabagic men, one of who has an allergic rhinitis. The clinical symptomatology is evocative of our patients and is especially marked by the unilateral nasal obstruction.

[Ossifying fibroma of the maxilla (apropos of 2 cases)].

The ossifiant fibroma is an authentic scarce benign tumoral processus. According to a literature review and two recent cases taken in charge in our service, having stand diagnostical and therapeutical problems. They seem interesting to accost the subject of the ossifiant fibroma in maxillo-facial surgery and put the accent on the differential diagnosis in histological plane between ossifiant fibroma and fibrous dysplasia having given different therapeuticals indicents.

[True osteoma of the maxilla. Apropos of 3 cases].

The authors report 3 cases of authentic maxillary osteoma. Two cases concerns an exceptional osteoma with multiple localisation and the third case a giant maxilla osteoma. Topographic, diagnostic and therapeutic notions of these tumors are related.

[A curiosity in ORL pathology: myiasis of the otorhinolaryngologic cavities].

The authors report a case of auricular myiasis with a review of literature. Diagnostic, therapeutic and prophylactic means established facing this parasitical disease are analysed.

[Ethmoid-frontal mucocele. Apropos of 15 cases from 1985 to 1990].

Between 1985 and 1990, 15 ethmoid frontal mucoceles were collated. All our patients consulted us at the exteriorization stage. A CT-scan is the ideal examination, making it possible to assert the diagnosis and to individualize the bone destruction and the neighbouring tissue repression.

[Mucocele of the maxillary sinus. Apropos of 3 cases].

Mucocele of the maxillary sinus is a rare affection his pathogenesis is still discussed, with a prevalence of the injury's and inflammatory's theories. The diagnosis being confirmed by computed tomography imaging ..

[Suppuration of old open cavities. Radical treatment].

The use of small, Davis-type, cutaneous grafts, enabled drying up of draining cavities where suppuration persisted despite all treatment. At the same time, hearing was improved by a cartilage arch from the septum which had vibratory and anti-retractile effects.

[Davis grafts in the treatment of chronic suppuration of hollowed-out cavities].

A surgical technique in suppurative cavities is reported. Epithelial Davis grafts are used to stimulate the epidermization process in radical cavities.

[Pathology and surgery of tumors located under the internal auditory canal. 1. Neurinoma of mixed nerves].

The schwannomas of foramen jugulare are infrequent although progress in diagnosis of these tumors have been obtained by CT scan. We report five cases of the caudal nerves that where developed into the foramen jugulare. One may suspect these tumors in presence of any minimal, unilateral defect of otological, facial and pharyngo-laryngeal functions.
