Prevalence of tinnitus and hyperacusis in 9-12-year-old children.

OBJECTIVES: To estimate the prevalence of tinnitus and hyperacusis in children aged 9-12 years in Flanders, as well as to explore the associations with hearing abilities and listening behaviours. DESIGN: A cross-sectional survey was undertaken in four different Flemish schools. The questionnaire was distributed among 415 children, with a response rate of 97.3%. RESULTS: The prevalence of permanent tinnitus was 10.5% and of hyperacusis was 3.3%. The hyperacusis prevalence was higher in girls (p < .05). Some children reported effects of tinnitus in terms of anxiety (20.1%), sleep (36.5%), and concentration (24.8%). When listening to personal listening devices, 33.5% of the children reported to listen for at least 1 h at 60% or higher of the volume range. Moreover, 54.9% of children stated to never wear hearing protection. CONCLUSIONS: Tinnitus and hyperacusis are prevalent in children aged 9-12 years. Some of these children might be overlooked and, as such, not receiving the required follow-up or counselling. Development of guidelines for the assessment of these auditory symptoms in children would help to determine the prevalence numbers with greater accuracy. Sensibility campaigns for safe listening are warranted, as more than half of the children never use hearing protection.

Effectiveness of nitrous oxide sedation for otolaryngologic examination in the outpatient clinic in uncooperative children.

OBJECTIVES: The aim of this study is to investigate the efficacy of equimolar mixture of 50% nitrous oxide and oxygen (EMONO) to obtain conscious sedation for otolaryngologic examinations and minor Ear-Nose-Throat (ENT) procedures in children with or without comorbidities. METHODS: Retrospective analysis of patient records from all children who were uncooperative during routine ENT examination, and therefore underwent otomicroscopic examinations and/or minor ENT procedures sedated with EMONO in the outpatient ENT clinic. The following data were collected: patients characteristics, sedative effect, analgesic effect and adverse effects. Patients were divided into three subgroups: 1) no relevant comorbidities, 2) Down Syndrome and 3) other causes of behavioural problems or developmental delay. RESULTS: Data were analyzed for 99 patients (170 procedures). Seven procedures failed. A good to excellent sedative and analgesic effect was obtained in most patients without a difference between subgroups. Minor and transient side effects were encountered in one third (34%) of the patients. CONCLUSIONS: EMONO is an effective agent to achieve conscious sedation and to perform ENT examinations or minor procedures in otherwise uncooperative children with or without developmental delay.

The use of melatonin for auditory brainstem response audiometry in children with comorbidities.

PURPOSE: In this study, the efficacy and feasibility of melatonin in young children with and without comorbidities, undergoing auditory brainstem response audiometry (ABR) was evaluated. The aim of this study was primarily to evaluate the use of melatonin for ABR investigations in children with comorbidities. Second, the efficacy of melatonin was evaluated based on several factors like sleep-onset latency, sleep duration, frequency of awakenings as well as adverse events. METHODS: Click-induced ABR tests were performed at the outpatient clinic between January, 2018 and August, 2020. Investigations were considered successful when binaural testing was completed. A dose of melatonin depending on age, 5 mg for children younger than 6 years and 10 mg if older than 6 years, was administered after placement of electrodes. RESULTS: 131 children were included in this study. 87% of all ABR investigations were performed successfully. Comorbidities such as neurodevelopmental disorders or developmental delays were present in 70% of all children. There was no significant difference in age (p = 0.36) or gender (p = 0.97) between the success and failed group. In addition, comorbidities were equally distributed between both groups. Mean sleep duration was 38 (SD 21) min and sleep-onset latency was 28 (SD 20) min No adverse events were documented. CONCLUSION: Melatonin is effective for ABR examinations in infants and children with and without comorbidities. Furthermore, it allows for sequential testing in those at risk for progressive hearing loss. Clear instructions to caregivers and expertise of audiologists are a prerequisite for optimal outcomes.

Impact of superior ophthalmic vein thrombosis: a case series and literature review.

Purpose: To present nine new cases of superior ophthalmic vein thrombosis (SOVT) and compare these with the literature, and to assess the impact of SOVT for the clinician. Methods: Using the data bases of the Department of Ophthalmology of the AMC, we searched for patients with radiologically evidenced SOVT between January 2006 and December 2014. In addition, a PubMed search, using the mesh term 'superior ophthalmic vein thrombosis', was done. Results: We found nine patients with SOVT. In three patients, SOVT was related to dural arteriovenous fistulae. In one patient, it was caused by the acute reversal of warfarin by vitamin K. In two patients, an infectious cause was found. In three patients, the cause of SOVT was not found despite screening for coagulation and other disorders. All patients presented with eyelid swelling, proptosis, and/or motility impairment. We found complete recovery in four patients. Three patients had mild sequelae and two patients had severe visual impairment. In the literature, we found 60 cases reporting on SOVT with various aetiologies. Clinical presentation, treatment modalities, and outcomes were comparable to our findings. Conclusion: Our case series and literature review show that SOVT can occur simultaneously with cavernous sinus thrombosis (CST) but can also be a separate entity. Clinical presentation can mimic orbital cellulitis (OC) or CST and when no signs of OC can be found, an alternative cause for SOVT should be sought. When timely and adequate treatment is conducted, the prognosis is predominantly favourable.

Prognosis of septic cavernous sinus thrombosis remarkably improved: a case series of 12 patients and literature review.

PURPOSE: Septic cavernous sinus thrombosis (CST) is a rare complication of infections in the head and neck area. CST is notorious for its bad prognosis, with high mortality and morbidity rates described in literature. However, these rates are based on old series. We question whether the prognosis of CST is currently still as devastating. The primary purpose of this study is to assess the mortality and morbidity of CST. METHODS: Using the databases of all relevant specialties in our tertiary referral hospital, we collected all the patients treated for CST in the period 2005-2017. In addition, a PubMed search, using the mesh term 'cavernous sinus thrombosis', was performed. RESULTS: We found 12 patients with CST in the study period. Of the 12 patients, 11 survived and 9 recovered without any permanent deficits. Seven patients were treated with anticoagulation, and in none of the patients we saw hemorrhagic complications. In literature, older articles describe higher mortality rates (14-80%), but more recent articles report mortality and morbidity rates similar to our results. CONCLUSIONS: The prognosis of CST nowadays is more favorable than previously described. Anticoagulation seems to be a safe addition to antibiotic and surgical treatment, at least in patients without central nervous system infection.

True abscess formation is rare in bacterial orbital cellulitis; consequences for treatment.

BACKGROUND: Pre- or retroseptal bacterial orbital cellulitis (pOC/rOC) is not an uncommon orbital disease. Treatment consists of antibiotics with or without surgical drainage. Several questions regarding course, complications and outcome of treatment are unanswered and the indication for surgery is not well defined. The aim of this study is to: 1. describe the outcome of orbital cellulitis (OC) in a large cohort, 2. assess the significance of Chandler's classification, 3. assess the incidence of abscess formation in OC, and 4. redefine criteria for surgery. METHODS: Retrospective case series of patients with OC seen between 1-1-2007 and 1-1-2014 in a tertiary referral center. RESULTS: Sixty-eight patients presented with (presumed) bacterial pOC. Two out of these 68 developed rOC. All 68 patients had a full recovery. Forty-eight patients presented with rOC. Four out of 48 (8%) had intracranial extension of the infection at the time of admission. No admitted patient developed distant seeding. Only four (8%) patients with rOC had a true orbital abscess. In the other 92% we found a diffuse orbital inflammation or a subperiosteal empyema. Forty-four (92%) patients with rOC had a full recovery. CONCLUSIONS: 1. The prognosis of both pOC and rOC nowadays is generally favorable. 2. Chandler's classification is of little use. 3. True abscess formation in OC is rare. 4. The indication for surgical intervention must be based on the clinical presentation and the assessment of true orbital abscess formation.

[A smoker with hoarseness and a swelling of his neck]. / Een hese roker met een zwelling in de hals.

A 68-year-old man was referred to the Department of Otolaryngology because of a swelling of his neck and hoarseness. CT imaging of his neck revealed a cystic mass in the larynx as well as in the neck, with an air-fluid level. The diagnosis 'laryngopyocele' was made.

[Local complications of intranasal cocaine abuse: diagnostic and therapeutic guidelines]. / Lokale complicaties van intranasaal cocaïnegebruik: een diagnostische en therapeutische leidraad.

In addition to causing nasal septum perforation, cocaine abuse can cause extensive destruction of the osteocartilaginous structures of the nose. The clinical picture can mimic other diseases, such as vasculitis and lymphoma. Here we describe 3 patients with nasal deformities. One patient, a 39-year-old woman, had a large cocaine-related septum perforation, which caused a saddle-nose deformity. This deformity was corrected via external-approach rhinoplasty. The second patient, a 58-year-old man with limited granulomatosis with polyangiitis, presented with recurrent nose bleeds. He was treated with prednisolone for an exacerbation of symptoms. His nasal defects are now stable. The third patient, a 41-year-old man, had extensive deformities and tissue defects of the nose and palate. He was treated surgically, but this was followed by a relapse of the tissue defects due to persistent cocaine abuse. In patients with destruction of the nasal skeleton, the possibility of cocaine abuse should always be considered.

Soft versus firm catheters for intrauterine insemination.

BACKGROUND: Intrauterine insemination (IUI) is a recommended treatment for unexplained subfertility. The treatment involves the direct delivery of spermatozoa into the uterus using a catheter. Many factors influence the success of IUI treatments including the type of catheter used. OBJECTIVES: To compare pregnancy-related outcomes from women undergoing intrauterine insemination cycles performed with either soft or firm catheters in subfertile women. SEARCH STRATEGY: We searched the following databases (inception to July 2010) with no language restrictions: Cochrane Menstrual Disorders and Subfertility Group Specialised Register, CENTRAL (The Cochrane Library), MEDLINE, EMBASE, PsycINFO, CINAHL, LILACS and OpenSigle. We also searched the conference abstracts in the ISI Web of Knowledge and Google, and conference abstracts and citation lists of relevant publications, reviews and included studies. SELECTION CRITERIA: We included only truly randomised controlled studies of women who underwent IUI using either soft or firm catheter types and reporting data on rates of live birth, clinical pregnancy, multiple pregnancy, miscarriage, ease of introduction of the catheter, occurrence of trauma, or woman's discomfort. DATA COLLECTION AND ANALYSIS: Two review authors screened the titles and abstracts of 78 potentially eligible studies and excluded 66 of these. We critically appraised the full texts of twelve studies and excluded three studies. Nine publications of six studies were remaining. We extracted data from the six remaining studies and there were no disagreements. We assessed risk of bias and pooled dichotomous data and presented the Peto odds ratios (OR) with 95% confidence intervals (CI). MAIN RESULTS: There was no evidence of a significant effect difference regarding the choice of catheter type for any of the outcomes. Three studies reported live birth rates (OR 0.94, 95% CI 0.65 to 1.35) with a translated OR percentages (1.3, 95% CI 0.56 to 3.1) while six studies reported clinical pregnancy rates (OR 1.0, 95% CI 0.73 to 1.35 ). Two studies were pooled for the analysis of miscarriages (OR 1.25, 95% CI 0.49 to 3.22). Results of other adverse outcomes were reported per cycle and were therefore not pooled. AUTHORS' CONCLUSIONS: On the basis of the evidence available in this review, no specific conclusion can be made regarding the superiority of one catheter class over another. Further adequately powered studies reporting on clinical outcomes (e.g. live birth rate) are required. Additional outcomes such as miscarriage rates and measures of discomfort need to be reported.

Interventions for women with endometrioma prior to assisted reproductive technology.

BACKGROUND: Endometriomata are cysts of endometriosis in the ovaries. As artificial reproductive technology (ART) cycles involve oocyte pickup from the ovaries, endometriomata may interfere with the outcome of ART. OBJECTIVES: To determine the effectiveness and safety of surgery, medical treatment, combination therapy or no treatment for improving reproductive outcomes among women with endometriomata, prior to undergoing ART cycles. SEARCH STRATEGY: The review authors searched: Cochrane Menstrual Disorders and Subfertility Group Specialised Register of trials, CENTRAL (The Cochrane Library), EMBASE, MEDLINE, PubMed, PsycINFO, CINAHL, DARE, trial registers for ongoing and registered trials, citation indexes, conference abstracts on the ISI Web of Knowledge, Clinical Study Results, OpenSIGLE (July 2010) and handsearched Fertility and Sterility (2008 to 2010). SELECTION CRITERIA: Randomised controlled trials of any medical, surgical or combination therapy or expectant management for endometriomata prior to ART. DATA COLLECTION AND ANALYSIS: The trials were independently identified and assessed for risk of bias by two authors. The authors of the trials that were potentially eligible for inclusion were contacted for additional information. Outcomes were expressed as Peto odds ratios and mean differences (MD). MAIN RESULTS: Eleven trials were identified of which seven were excluded and four with 312 participants were included.No trial reported live birth outcomes. One trial compared gonadotropin-releasing hormone (GnRH) agonist with GnRH antagonist. There was no evidence of a difference for clinical pregnancy rate (CPR), however the number of mature oocytes retrieved (NMOR) was greater with GnRH agonists (MD -1.60, 95% CI -2.44 to -0.76) and the ovarian response was increased (estradiol (E2) levels on day of human chorionic gonadotropin (hCG) injection) (MD -456.30, 95% CI -896.06 to -16.54).Surgery (aspiration or cystectomy) versus expectant management (EM) showed no evidence of a benefit for clinical pregnancy with either technique. Aspiration was associated with greater NMOR (MD 0.50, 95% CI 0.02 to 0.98) and increased ovarian response (E2 levels on day of hCG injection) (MD 685.3, 95% CI 464.50 to 906.10) compared to EM.Cystectomy was associated with a decreased ovarian response to controlled ovarian hyperstimulation (COH) (MD -510.00, 95% CI -676.62 to -343.38); no evidence of an effect on the NMOR compared to EM. Aspiration versus cystectomy showed no evidence of a difference in CPR or the NMOR. AUTHORS' CONCLUSIONS: There was no evidence of an effect on reproductive outcomes in any of the four included trials. Further RCTs of management of endometrioma in women undergoing ART are required.
