Outcome of childhood epistaxis with treatment of allergic rhinitis: a randomized controlled study.

The purpose of this study is to (1) to determine if treatment of underlying allergic rhinitis (AR) in children will affect epistaxis outcome, (2) to compare efficacy of three outpatient AR treatment regimens in epistaxis outcomes, and (3) to investigate potential factors in the pathogenesis of epistaxis with underlying AR. A single-blind randomized-controlled study was conducted in the Otolaryngology clinic in KK Women's and Children's Hospital. Sixty children aged below 18 years with underlying untreated AR, with first presentation of epistaxis, were randomized to three different AR treatments: treatment 1, antihistamine (20 patients); treatment 2, nasal steroid spray (20 patients); and treatment 3, both antihistamine and nasal steroid spray (20 patients). Epistaxis severity and frequency were assessed. Pre-treatment, 95% of patients within each of the three treatment groups described epistaxis symptoms. Post-treatment, there was improvement in epistaxis outcome (resolution of epistaxis) with 20% (4/20), 40% (8/20), and 60% (12/20) of patients in treatment groups 1 (antihistamine), 2 (nasal steroid spray), and 3 (combined therapy) respectively, who reported resolution of epistaxis. Treatment regimens containing nasal steroid spray resulted in greater improvement of epistaxis severity and frequency. Combined therapy (treatment 3) resulted in the best epistaxis outcome at 1-month follow-up. Majority (90%) reported nose-picking/rubbing behavior. CONCLUSIONS: Intranasal corticosteroids are superior to oral antihistamines in relieving itch or rhinorrhea in AR. Intranasal corticosteroids may be important in treating epistaxis with underlying AR, because digital trauma from itch/rhinorrhea-related nose-picking/rubbing frequently leads to epistaxis. Results from this study will be important to primary and emergency physicians, community pediatricians, and pediatric allergists and otolaryngologists. WHAT IS KNOWN: • Childhood epistaxis commonly co-exists with allergic rhinitis (AR), causing significant symptoms and distress to patients. • There are currently no studies reporti ng on epistaxis outcome aft er treatment of underlying AR. WHAT IS NEW: • This is a single-blind randomized-controlled study of 60 children aged below 18 years with underlying untreated AR, with first presentation of epistaxis to a children's hospital in Singapore Patients were randomized to three different regimens to treat AR: treatment 1, antihistamine; treatment 2, nasal steroid spray; and treatment 3, both antihistamine and nasal steroid spray. • Treatment regimens containing nasal steroid spray improved epistaxis outcomes, with combined therapy of antihistamine and nasal steroid spray resulting in the best outcome for resolution of epistaxis among the three treatment regimens.

Good hearing outcome in children recovering from non-polio enteroviral meningitis.

AIM: Evaluation of hearing outcome in children following non-polio enteroviral meningitis (EVM). METHODS: We reviewed hearing outcome of children, aged ≤15 years, with EVM managed at our institution over a 4-year period from July 2008 to July 2011 and January-December 2015. Children with concomitant bacterial infections, and those who required intensive care, or with a prior history of hearing impairment or immunodeficiency were excluded. Data on demographics, medical history, presentation and outcome of hearing screen were collected. The children attended post-meningitis review and hearing screen utilising transient-evoked otoacoustic emission testing at 8-10 weeks. Children who failed the transient-evoked otoacoustic emission testing and those with caregiver concerns were referred to otolaryngology for comprehensive audiologic evaluation. RESULTS: The study cohort consisted of 179 children, aged from 3 days to 15 years, of whom 158 (89%) were younger than 90 days of age. Eleven were preterm infants. A total of 158 children had received intravenous gentamicin at 5-7.5 mg/kg/day for a median duration of 2 days. All 179 study participants were found to have good hearing post EVM. CONCLUSION: Hearing outcome in children recovering from EVM is good.

Successful rehabilitation with cochlear implant in post-irradiation induced hearing loss in nasopharyngeal carcinoma patient.

INTRODUCTION: We report a case of successful rehabilitation of hearing with a cochlear implant in a patient with nasopharyngeal carcinoma who developed post-irradiation hearing loss following treatment. CLINICAL PICTURE: A 55-year-old Chinese lady suffered from radiation-induced sensorineural hearing loss due to treatment for nasopharyngeal carcinoma. Audiological tests and imaging studies showed an intact retrocochlear pathway. TREATMENT: Cochlear implantation. OUTCOME: Cochlear implant was done with successful rehabilitation of hearing until the time of this report. CONCLUSIONS: If functionally active auditory fibres survive with no recurrent tumour, successful rehabilitation of post-irradiation induced sensorineural hearing loss is possible with a cochlear implant in a patient with nasopharyngeal carcinoma.

Repair of nasal septal perforations using auricular conchal cartilage graft in children: report on three cases and literature review.

OBJECTIVES: Repair of nasal septal perforation is a challenging procedure. Numerous methods have been described to close nasoseptal perforations with varying degrees of success. The lack of a consensus on nasoseptal perforation repair reflects the shortcomings of each method. There has been a paucity of literature on nasoseptal repair in the paediatric age group. We report our experience of repair of nasal septal perforation secondary to button battery injury using auricular conchal cartilage in the paediatric population. METHODS: Retrospective review of case notes and close regular follow-up of the patients since their first presentations with button batteries as foreign bodies in the nose. RESULTS: Three out of the three children who underwent repair of the nasal septum achieved successful closure of the nasal septum. One child with a large septal perforation required three procedures to achieve closure of the perforation. CONCLUSIONS: Repair of nasal septal perforations is a challenging procedure especially in children. Good results can be achieved with auricular conchal cartilage graft.

Auditory neuropathy/auditory dys-synchrony detected by universal newborn hearing screening.

The implementation of neonatal hearing screening has enabled early detection and intervention in hearing loss. The use of otoacoustic emissions (OAE) and auditory brainstem response testing in universal screening has led to the recognition of this recently described disorder called auditory neuropathy/auditory dys-synchrony (AN/AD). This diagnosis indicates that the infant has significant hearing loss despite having normal outer hair cells in the cochlea. We reviewed the characteristics and natural history of nine infants detected to have AN/AD from universal newborn hearing screening in a national pediatric hospital. Fifty-two cases of hearing loss were detected from 14,807 consecutively screened cases. Of the 52 cases, 9 had electrophysiological test results consistent with AN/AD. They include both premature infants who had major neonatal complications and term infants with no perinatal complications. Six cases had bilateral and three cases had unilateral findings. We suggest that AN/AD can occur in low-risk infants and hence screening of high-risk cases alone is insufficient. Our findings are discussed with reference to the current literature.

A novel stent for the treatment of persistent buccopharyngeal membrane.

We describe a new stent design for treatment of persistent buccopharyngeal membrane. The patient is a male child diagnosed at birth with persistent buccopharyngeal membrane, managed in our institution from birth to present age of 2.5 years. We describe to problems and challenges in management for this rare anomaly by means of a custom made polyurethane stent.

Postirradiation sarcoma of the sphenoid bone--a case report.

INTRODUCTION: The development of secondary tumours as a result of radiation therapy is a rare but serious complication. CLINICAL PICTURE: This is a case report of a 45-year-old Chinese male who developed postirradiation sarcoma of the sphenoid bone in less than 5 years after radiation therapy for Stage T3N1M0 nasopharyngeal carcinoma. DISCUSSION: In the literature, the only case of postirradiation osteosarcoma of the sphenoid bone was after radiation therapy for craniopharyngioma. There was no previously reported case of postirradiation sarcoma of the sphenoid bone after radiation therapy for nasopharyngeal carcinoma. CONCLUSION: This is the first case of postirradiation malignant fibrous histiocytoma of the sphenoid to be reported. Of about 3000 patients treated with radiotherapy for nasopharyngeal carcinoma over a 10-year period in Singapore, only 1 patient developed postirradiation tumour of the sphenoid bone.

Pediatric tracheotomies in an Asian population: the Singapore experience.

OBJECTIVE: Over the past 2 decades, tracheotomy in children and infants has evolved from a primarily emergent procedure for upper airway obstruction into a semielective procedure for airway access in assisted ventilation. We present a 12-year retrospective review of tracheotomies performed in the pediatric population in Singapore. STUDY DESIGN AND SETTING: We reviewed all tracheotomies performed in children below the age of 16 years in 2 tertiary pediatric medical centers in Singapore from January 1991 to December 2003. Indications for surgery are reviewed, and outcomes in terms of morbidity rate, mortality rate, postoperative rehabilitation, and duration of decannulation process were analyzed. RESULTS: Tracheotomies were performed in 48 children during the study period. The mean age of patients was 3.24 years, with ages ranging from 16 days to 14 years. Sixty-three percent of tracheotomies were done within the 1st year of life. The chief indication was airway access for assisted ventilation. The overall complication rate was 31%. There were 13 attempts at decannulation, with 9 successes. No tracheotomy-related deaths occurred. CONCLUSION: Tracheotomy is a relatively safe procedure in children and infants. Lower decannulation rates and the evolving role of tracheotomy for early access in assisted ventilation permits earlier discharge with tracheotomy in situ.

The development of sphenoid sinus in Asian children.

OBJECTIVES: (1) To study the developmental changes of sphenoid sinus in Asian children and (2) to test the hypothesis that the sphenoid sinus may be developing slower in Asian, by comparing the growth patterns between Asian and Caucasian children. MATERIALS AND METHODS: Review of MR imaging of the skull of 220 Asian children less than 15 years of age in a tertiary hospital. The results were compared to a representative Caucasian study by Szolar et al. [Surg. Radiol. Anat., 16 (1994) 193]. RESULTS: Grade 1 sphenoid was present in all children less than 6 months old. Conversion from marrow to fat of the sphenoid sinus (Grade 2) began at 7 months and was present in patients up to 6 years old. Signs of pneumatization (Grade 3) of the sphenoid sinus were first noted in patients at 10 months old. Almost 100% pneumatization was seen in all the children after 6 years old except for one child with Grade 1 sphenoid at 11 years old. Compared to Caucasian children, there was a significantly higher proportion of Grade 3 cases in Asian children from 0 to 4 years of age (P = 0.05). No difference in the distribution of cases was noted from 4 to 8 years (P = 0.466) and 8-15 years (P = 1.00). CONCLUSION: The developmental changes of the sphenoid sinus in Asian children were determined and found to be similar when compared to Caucasian children. The findings did not support the hypothesis that the Asian sphenoid sinus is developing slower compared to that of the Caucasians.

Hearing Loss in Newborns with Cleft Lip and/or Palate.

INTRODUCTION: This study aims to review the results of hearing screens in newborns with cleft deformities. MATERIALS AND METHODS: A retrospective audit of 123 newborns with cleft deformities, born between 1 April 2002 and 1 December 2008, was conducted. Data on the results of universal newborn hearing screens (UNHS) and high-risk hearing screens, age at diagnosis, severity/type of hearing loss and mode of intervention were obtained from a prospectively maintained hearing database. RESULTS: Thirty-one of 123 newborns (25.2%) failed the first automated auditory brainstem response (AABR). Seventy percent of infants (56 out of 80) who passed the UNHS failed the high-risk hearing screens which was conducted at 3 to 6 months of age. Otolaryngology referral rate was 67.5% (83/123); 90.3% of 31 newborns who failed the first AABR eventually required otolaryngology referrals. Incidence of hearing loss was 24.4% (30/123; 25 conductive, 2 mixed and 3 sensorineural), significantly higher than the hospital incidence of 0.3% (OR: 124.9, 95% CI, 81.1 to 192.4, P <0.01). In terms of severity, 8 were mild, 15 moderate, 5 severe, 2 profound. Eighteen out of 30 infants (60%) were detected from the high-risk hearing screens after passing the first AABR. CONCLUSION: These newborns had a higher risk of failing the UNHS and high-risk hearing screen. There was a higher incidence of hearing loss which was mainly conductive. Failure of the first AABR was an accurate predictor of an eventual otolaryngology referral, suggesting that a second AABR may be unnecessary. High-risk hearing screens helped to identify hearing loss which might have been missed out early on in life or which might have evolved later in infancy.

Allergic rhinitis and non-allergic rhinitis in children in the tropics: prevalence and risk associations.

BACKGROUND: The age-related comparative prevalence of allergic rhinitis (AR) and non-allergic rhinitis (NAR) in children is poorly defined. We aimed to characterize AR and NAR in children. METHODS: This study enrolled children with chronic rhinitis who presented to a tertiary paediatric center for a diagnostic skin prick test (SPT). Parents completed a medical history questionnaire for their child, including disease activity for asthma and rhinitis. Sociodemographic data was obtained and all participants underwent a common inhalant SPT panel. A positive SPT indicated AR. RESULTS: From March 2001 to March 2009, 6,660 children (64% male) were enrolled (aged 6 months to 19 years, mean 7.82 years). Only 3.7% (249) of the children were <2 years old, and almost 30% of these had AR. Most children with AR (73%) presented after age 6. Males were more likely to have AR (vs. NAR) (OR 1.5; CI 1.39-1.77). Antihistamine and salbutamol use did not differ between children with AR and NAR. Children with AR were more likely to require adjunct therapy with inhaled corticosteroids (51.2% vs. 43.2%, P < 0.001), have drug hypersensitivity (especially antipyretic drugs) (2.5% vs. 1.3%, P = 0.384) or an asthma admission (9.1% vs. 6.0%, P < 0.001). CONCLUSIONS: AR is more common in male children, is relatively rare below the age of 2 years, and accounts for two-thirds of all childhood chronic rhinitis and 73.3% of all chronic rhinitis in school-aged children (≥6 years old). Children with AR have more severe rhinitis symptoms and more often suffer from asthma-related events and admissions.
