Feasibility of day-case pediatric cochlear implantation.

PURPOSE: Pediatric cochlear implantation is performed on an outpatient basis in an inconstant way. The aim of this study is to assess the feasibility of day-case pediatric cochlear implantation by determining the acceptability of outpatient-to-inpatient conversion rate (acceptability threshold of 5%) and to assess the safety by comparing outpatient and inpatient postoperative events. We also want to identify conversion predictive factors. METHODS: We conducted a monocentric retrospective study including 267 cases aged 6 months to 18 years who underwent unilateral cochlear implantation between 2016 and 2020. This population was divided into two groups: outpatient group (190 cases) and inpatient group (77 cases). RESULTS: Among the 190 cases scheduled as day surgery, 9 cases required conversion to conventional hospitalization which leads to an outpatient-to-inpatient conversion rate of 4.7%. Postoperative nausea and vomiting (PONV) were involved in all cases of conversion. Conversion predictive factors were the presence of an inner ear malformation at risk of gusher (OR 32.51, 95% CI [4.98-370.27], p 0.001) and the intraoperative administration of morphine (OR 8.52, 95% CI [1.38-86.84], p 0.035). There was no statistically significant difference in immediate postoperative complications (outpatient 14.2% vs inpatient 16.9% p 0.715), early-stage complications (outpatient 12.6% vs inpatient 10.4% p 0.812) and early-stage unplanned consultations (outpatient 4.7% vs inpatient 3.9% p 0.748) between outpatient and inpatient groups. Unplanned readmissions were found only in the outpatient group. CONCLUSION: Day-case pediatric cochlear implantation is a feasible and safe procedure even in infants. The outpatient-to-inpatient conversion rate of 4.7% is considered acceptable but requires anticipation of human and accommodation needs. No causes of conversion were life-threatening. The risk of postoperative complications and unplanned consultations are not influenced by the mode of hospitalization. Special attention should be paid to the prevention of PONV and the presence of inner ear malformations.

Identification of transmission chains and clusters associated with COVID-19 in Tunisia.

BACKGROUND: The aim of this study was to characterize the transmission chains and clusters of COVID-19 infection in Tunisia. METHODS: All cases were confirmed by Reverse Transcriptase Polymerase Chain Reaction of a nasopharyngeal specimen. Contact tracing is undertaken for all confirmed cases in order to identify close contacts that will be systematically screened and quarantined. Transmission chains were identified based on field investigation, contact tracing, results of screening tests and by assessing all probable mode of transmission and interactions. RESULTS: As of May 18, 2020, 656 cases out of a total of 1043 confirmed cases of Coronavirus disease 2019 belong to 127 transmission chains identified during the epidemic (mean age 42.36 years, Standard deviation 19.56 and sex ratio 0.86). The virus transmission is the most concentrated in the governorate of Tunis (31.5%), Ariana (10.2%) and Ben Arous (10.2%). Virus transmission occurred 50 times (9.72% of secondary transmission events) between two different governorates. A maximum of seven generations of secondary infection was identified, whereas 62% of these secondary infections belong the first generation. A total of 11 "super spreader" cases were identified in this investigation. Four large clusters have been identified. The evolution of secondary cases highlighted two peaks: one in 2nd April and a second in 16 th April whereas imported cases caused local transmission of virus during the early phase of the epidemic. CONCLUSION: Correct contact tracing and early active case finding is useful to identify transmission chains and source of infection in order to contain the widespread transmission in the community.

Fusobacterium necrophorum, a major provider of sinus thrombosis in acute mastoiditis: A retrospective multicentre paediatric study.

OBJECTIVE: To evaluate in children the clinical severity and evolution of otogenic lateral sinus thrombosis (OLST) due to Fusobacterium necrophorum compared with other bacterial otogenic thrombosis and propose a specific management flowchart for Fusobacterium OLST. DESIGN: A retrospective multicentre cohort study. SETTINGS: Four French ENT paediatric departments. PARTICIPANTS: A total of 260 under 18 years old admitted for acute mastoiditis were included. Initial imaging was reviewed to focus on complicated mastoiditis and 52 OLST were identified. Children were then divided into two groups according to bacteriological results: 28 in the "OLST Fusobacterium group" and 24 in the "OLST other bacteria group". RESULTS: There was a significant association between F necrophorum and OLST (P < .001). When compared to the OLST other bacteria group, children in the OLST Fusobacterium group were significantly younger (61 months vs 23 months, P < .01) and had a more severe clinical presentation: higher CRP (113 mg/L vs 175.7 mg/L, P = .02) and larger subperiosteal abscess (14 mm vs 21 mm, P < .01). Medical management was also more intensive in the OLST Fusobacterium group than in the OLST other bacteria group: increased number of conservative surgeries (66.7% vs 92.9%, P = .03) and longer hospital stay (13.7 days vs 19.8 days, P = .02). At the end of follow-up, the clinical course was good in both groups without any neurological sequelae. CONCLUSIONS: Thrombotic complications are very frequent in case of Fusobacterium mastoiditis and clinicians should be aware of the initial severity of the clinical presentation. Under appropriate management, the clinical course of Fusobacterium OLST is as good as that of other bacterial otogenic thrombosis.

Switching the poles in sexual and reproductive health research: implementing a research capacity-strengthening network in West and North Africa.

Health research capacities have been improved in Africa but still remain weak as compared to other regions of the World. To strengthen these research capacities, international collaboration and networking for knowledge and capacity transfer are needed. In this commentary, we present the Network for Scientific Support in the field of Sexual and Reproductive Health in West and North Africa, its priority research topics and discuss its implementation process. Established in January 2014, the Network aims at generating human rights and gender-based research fully carried out and driven by South based institutions. It is composed of 12 institutions including the Institute of Tropical Medicine of Antwerp (Belgium) and 11 institutions from eight Francophone West and North African countries. The key areas of interest of this network are health policies analysis and health system research in family planning, HIV prevention among vulnerable groups, quality of care and breast cancers. Since it started, seventeen research proposals based on locally relevant research questions have been developed. Among the seventeen proposals, eleven have been implemented. Several research institutions enhanced linkages with local representations of international partners such as UNFPA. The network is committed to strengthening methodological research capacities and soft skills such as fundraising, advocacy and leadership. Such competencies are strongly needed for developing an effective South-based leadership in Sexual and Reproductive Health research, and for achieving the Sustainable Development Goals.

Long term outcome of laryngeal mobility disorder and quality of life after pediatric cardiac surgery.

INTRODUCTION: Laryngeal mobility disorder after a pediatric heart surgery is common (between 5 and 10% of cases), and has important consequences on swallowing, breathing and speaking. After reviewing the literature, the recovery rate is variable and the postoperative follow-up is often done on a short time frame. The primary objective of the study is to describe the recovery from laryngeal mobility disorder with a follow-up time of at least 5 years. The secondary objective is to describe of the quality of life of the child in terms of phonation and swallowing, and to identify potential risk factors for a lasting laryngeal mobility disorder. METHODS: We collected data (morphological characteristics and details of the procedures and medical care) on children who had undergone a heart surgery with risks of complications, between 2010 and 2015, and with a laryngeal mobility disorder detected after the surgery through nasal flexible laryngoscopy. During a follow-up consultation, carried at least 5 years after the surgery, we performed a nasal flexible laryngoscopy to assess whether or not the patient had recovered a full mobility of the larynx. Two questionnaires were also given to the patients, the pVHI and the PEDI EAT-10, to assess respectively the quality of their speech and of their swallowing function. RESULTS: The recovery rate for a laryngeal mobility disorder more than 5 years after surgery was found to be 65% (9 children out of the 14 included in the study). We identified a risk factor for the persistence of a laryngeal mobility disorder after surgery: the presence of an associated genetic syndrome, p = 0.025. Children with persistent laryngeal mobility disorder have an impaired quality of life score, using the pVHI scale, which correlates well with the flexible laryngoscopy findings, p = 0.033. CONCLUSION: Children with a lasting laryngeal mobility disorder have disabling respiratory and vocal symptoms in their daily lives. Nasal flexible laryngoscopy should therefore be systematically performed postoperatively after a surgery carrying risks. For improved patient management, early detection of these disorders by pharyngolaryngeal nasal flexible laryngoscopy in the aftermath of high-risk cardiac surgery is strongly advised, with prolonged follow-up.

The use of CT-scan in foreign body aspiration in children: A 6 years' experience.

INTRODUCTION: A foreign body aspiration is a risky situation, common in pediatric emergency. The "gold standard" to rule out a foreign body or proceed to its extraction, is rigid bronchoscopy (RB) under general anesthesia. However, RB is an intrusive exam with possible complications. Depending on authors, RB in emergency is a procedure at risk of complications in 4-17% of cases. Advances in radiology allow CT-scanners of fast acquisition and high definition, which could be used as an alternative to RB. MATERIALS AND METHODS: This is a retrospective analysis of 6 years from May 2010 to May 2016, in a tertiary referral center. All children that presented a foreign body aspiration suspicion and had a cervical-thoracic CT with multiplanar reconstruction were analyzed. RESULTS: 200 children were included. The average age was 30 months. 132 were considered normal and 68 pathological. Among the 68 RB performed for pathological scanner, a foreign body was found in 59 cases, and we had 9 cases of false positives. Among the 132 considered normal, 27 have had a RB despite this, due to persistent symptoms, all were negative; 105 were discharged home without endoscopy with monitoring instructions. 1 child was reviewed three months later for asthma, without second choking event reported. A new CT-scan found a foreign body that was removed by RB. Due to the nature of the foreign body it is very unlikely to link it to the first choking event, but retrospectively we cannot be certain. Considering this case as the only false negative, the negative predictive value (NPV) of CT was 99.2% and positive predictive value (PPV) of 83.8%. CONCLUSION: The use of CT -scan with multiplanar reconstruction in suspected foreign body aspiration is a reliable alternative to endoscopy under general anesthesia, especially in asymptomatic patients, avoiding too many negative endoscopies.

Diagnostic performance of multidetector computed tomography for foreign body aspiration in children.

OBJECTIVE: To evaluate the sensitivity of multidetector computed tomography for confirming suspected foreign body aspiration into the airways in children. METHOD: We conducted a multicentre prospective study of 303 children evaluated using multidetector computed tomography with axial analysis complemented by multiplanar reconstruction when required. The images were read by a radiologist before endoscopy then reviewed later by a senior radiologist blinded to the endoscopy findings. Endoscopy was performed routinely. RESULTS: Foreign bodies were found by endoscopy in 70 of the 303 children. The initial multidetector computed tomography reading was 94% sensitive and 95% specific. For the review, the images for 91 patients were excluded because of motion blurring or absence of larynx visualisation; in the remaining 212 patients, sensitivity was 98% and specificity 97%. CONCLUSION: Multidetector computed tomography as performed in our patients cannot replace endoscopy, which remains the reference standard. Nevertheless, multidetector computed tomography is sufficiently sensitive to be of value when foreign body aspiration is not considered initially or when endoscopy is likely to prove challenging.

Propranolol as first-line treatment of head and neck hemangiomas.

OBJECTIVES: To report the efficacy of propranolol as first-line treatment of head and neck hemangiomas in children and to present an optimized protocol for treating hemangiomas. DESIGN: Multi-institutional retrospective study. SETTING: Two tertiary care referral pediatric centers. PATIENTS: Thirty-nine children with head and neck infantile hemangiomas were treated. MAIN OUTCOME MEASURES: Review of clinical records. RESULTS: Propranolol was the sole treatment in 60% of patients and was started at a mean age of 4.1 months (age range, 1-11 months) for early interventions among 33 of 39 patients. Propranolol therapy resulted in lightening and reduction of hemangiomas at 37 of 39 locations within 2 days to 2 weeks. One subglottic hemangioma and 1 nasal tip hemangioma did not respond or showed only a partial response; in these patients, propranolol therapy was delayed and followed other treatment failures. After successful therapeutic regression, 6 recurrences occurred; when reintroduced, propranolol was again effective. Recurrences were avoided by prolonged treatment. Twenty-six hemangiomas occurring at locations for which corticosteroid treatment previously would not have been initiated (nose, lips, and parotid area) unless a complication had occurred were treated with propranolol and were rapidly controlled. The mean duration of propranolol therapy was 8.5 months. No instances of ß-blocker discontinuation because of complications occurred, but propranolol was substituted by acebutolol in 5 patients because of trouble sleeping. CONCLUSIONS: Propranolol is an effective treatment of head and neck infantile hemangiomas, especially when started early within the rapid growth phase, and is first-line treatment of orbit and larynx hemangiomas. The efficacy and tolerability of propranolol led us to treat some hemangiomas in patients whom we previously would have observed rather than subject to corticosteroid therapy. Relapse was avoided if treatment was prolonged after theoretical involution (age 12 months). Questions remain about optimal dosing and age at treatment cessation.

Fusion of MRIs and CT scans for surgical treatment of cholesteatoma of the middle ear in children.

OBJECTIVE: To evaluate the efficiency of diffusion-weighted magnetic resonance imaging (MRI) and high-resolution computed tomographic (CT) scan coregistration in predicting and adequately locating primary or recurrent cholesteatoma in children. DESIGN: Prospective study. SETTING: Tertiary care university hospital. PATIENTS: Ten patients aged 2 to 17 years (mean age, 8.5 years) with cholesteatoma of the middle ear, some of which were previously treated, were included for follow-up with systematic CT scanning and MRI between 2007 and 2008. INTERVENTIONS: Computed tomographic scanning was performed on a Siemens Somaton 128 (0.5/0.2-mm slices reformatted in 0.5/0.3-mm images). Fine cuts were obtained parallel and perpendicular to the lateral semicircular canal in each ear (100 × 100-mm field of view). Magnetic resonance imaging was undertaken on a Siemens Avanto 1.5T unit, with a protocol adapted for young children. Diffusion-weighted imaging was acquired using a single-shot turbo spin-echo mode. To allow for diagnosis and localization of the cholesteatoma, CT and diffusion-weighted MRIs were fused for each case. RESULTS: In 10 children, fusion technique allowed for correct diagnosis and precise localization (hypotympanum, epitympanum, mastoid recess, and attical space) as confirmed by subsequent standard surgery (positive predictive value, 100%). In 3 cases, the surgical approach was adequately determined from the fusion results. Lesion sizes on the CT-MRI fusion corresponded with perioperative findings. CONCLUSIONS: Recent developments in imaging techniques have made diffusion-weighted MRI more effective for detecting recurrent cholesteatoma. The major drawback of this technique, however, has been its poor anatomical and spatial discrimination. Fusion imaging using high-resolution CT and diffusion-weighted MRI appears to be a promising technique for both the diagnosis and precise localization of cholesteatomas. It provides useful information for surgical planning and, furthermore, is easy to use in pediatric cases.

Prognostic factors of recurrent respiratory papillomatosis from a registry of 72 patients.

CONCLUSIONS: The database revealed severity factors relating to human papillomavirus (HPV) type and age at diagnosis. While not exhaustive, the database is easy to use and could serve for a European multicentre epidemiological study. OBJECTIVES: To propose a database as a starting point for a national registry and to estimate prognostic factors in recurrent respiratory papillomatosis (RRP). MATERIALS AND METHODS: This was a retrospective study carried out in a tertiary care teaching hospital. From January 2005 to July 2007, epidemiological, clinical and treatment information on patients undergoing endoscopy for RRP in the department was entered in a database. Data were collected on three forms: the first comprised information about disease history before assessment in the department, the second about the disease and its treatment in the department, and the third about evolution after treatment. RESULTS: Data on 72 patients were entered into an RRP database between January 2005 and July 2007. In all, 82% had already been treated for RRP in a different centre; 24 had juvenile-onset (JORRP) and 48 adult-onset (AORRP) papillomatosis. Cidovir injections had been administered to 91% of the patients. Histology found nine cases of dysplasia, one of carcinoma in situ and one of invasive carcinoma. Subglottic and tracheal locations were significantly more frequent in JORRP than in AORRP, as were the maximum Derkay scores and annual numbers of endoscopies. Patients with type 11 HPV had significantly more endoscopies per year than those with type 6.

Thulium laser in airway diseases in children.

PURPOSE OF REVIEW: To specify the characteristics of the thulium laser and to evaluate the advantages and possibilities of treatment with this laser in laryngotracheal diseases in children. RECENT FINDINGS: Fiber-based lasers have facilitated a new style of surgery. When performing therapeutic airways endoscopies there is the possibility of good control of lesions and adequate visualization of the surgical field using the telescope. Different types of laser may be used but the 2013-nm thulium laser shows promise as a laser that is efficient in soft tissues with the advantages of the other lasers without their problems. The thulium laser has been described in treating urinary tract abnormalities and recently airways diseases in adults, but there are no reports of other uses for this technique in the pediatric airway. SUMMARY: The thulium laser appears to be an interesting tool in the management of laryngotracheal diseases such as subglottic stenosis, tracheal granuloma and laryngomalacia. The use of this laser in laryngotracheal diseases in children will probably progress in the future.
