Hearing Loss among Children Visiting Department of Otolaryngology and HNS of a Tertiary Care Centre.

Introduction: Hearing loss is defined as the partial or total reduction in auditory acuity. Hearing loss can cause detrimental effects on speech, language, developmental, educational, and cognitive outcomes in children. This study aimed to find out the prevalence of hearing loss among children visiting the Department of Otolaryngology and HNS of a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among children visiting the Department of Otolaryngology and HNS between 1 January 2022 and 31 December 2022 after obtaining ethical approval. All the patients who underwent pure tone evaluation were included in the study. A convenience sampling technique was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 3051 children, 328 (10.75%) (9.65-11.85, 95% Confidence Interval) had hearing loss. Among children with hearing loss, 170 (51.83%) of children were female. The mean age of children with hearing loss was 13.31±3.39 years. The mean pure tone average among 452 ears with hearing loss was 44.60±17.71 dB. The commonest degree of hearing loss was mild hearing loss 266 (58.85%), and the commonest type was conductive hearing loss 310 (68.58%). Among children with hearing loss, 124 (37.80%) had bilateral hearing loss. Conclusions: The prevalence of hearing loss among children visiting the Department of Otolaryngology and HNS was found to be lower than similar studies done in similar settings. Keywords: audiology; audiometry; hearing loss; outpatients; prevalence.

Chronic Otitis Media among Patients Visiting Community-Based Static Outreach Clinics.

Introduction: Chronic otitis media is a chronic inflammation of the middle ear and mastoid cavity, with recurrent ear discharges or otorrhoea through a tympanic perforation for the past 3 months. It is a common cause of hearing impairment, disability, and poor scholastic performance and can lead to fatal intracranial infections and acute mastoiditis. This study aimed to find out the prevalence of chronic otitis media among patients visiting community-based static outreach clinics. Methods: A descriptive cross-sectional study was conducted among patients visiting the community-based static outreach clinics from 1 January 2017 to 31 December 2019. The ethical approval was taken from the Ethical Review Board. The diagnosis of chronic otitis media was done using otoscopy. The records of patients coming to outreach clinics visiting for ear, nose and throat care were reviewed using a pre-designed study proforma. A systematic random sampling method was used. The point estimate was calculated at a 95% Confidence Interval. Results: Among 385 patients, 37 (9.61%) (6.67-12.55, 95% Confidence Interval) had chronic otitis media. The mean age of patients with chronic otitis media was 27.59±13.24 years, with 28 (75.67%) patients aged between 18-60 years. Among them, 30 (81.08%) had unilateral and 34 (91.89%) had a mucosal type. Conclusions: The prevalence of chronic otitis media was lower than in other studies done in similar settings. Keywords: community health services; otitis media; patients; prevalence.

Keratosis obturans: A rare cause of facial nerve palsy.

Keratosis obturans, caused by the deposition of desquamated keratin plug in the external auditory canal can present with facial palsy. Young patients presenting with facial palsy, earache, and gradual hearing loss should be suspected for Keratosis obturans.

Safety and efficacy of Direct Oral Anticoagulants in cerebral venous thrombosis: A meta-analysis.

Cerebral venous thrombosis (CVT) is caused by partial or complete occlusion of the major cerebral venous sinuses or the smaller feeding cortical veins which predispose to the risk of venous infarction and hemorrhage. Current guidelines recommend treating CVT with either low-molecular-weight heparin (LMWH) or unfractionated heparin (UFH) followed by an oral vitamin K antagonist (VKA) for 3-12 months. Direct oral anticoagulants (DOACs) have already established benefit over warfarin as a long-term treatment of symptomatic venous thromboembolic disorder like deep vein thrombosis (DVT), and pulmonary embolism (PE) given its equal efficacy and better safety profile. The benefit of DOACs over warfarin as a long-term anticoagulation for CVT has likewise been extensively studied, yet it has not been approved as first-line therapy in the current practice. We therefore performed a systematic review and meta-analysis of relevant studies to generate robust evidence regarding the safety and efficacy of DOACs in CVT. This meta-analysis demonstrates that the use of DOACs in CVT has similar efficacy and safety compared to VKAs with better recanalization rate.

Natural expulsion of a sharp iron nail: Right main bronchus to the alimentary tract: A case report.

A young girl inhaled a pointed iron nail into the right main bronchus. However, both rigid bronchoscopy and oesophagoscopy failed to locate the nail. Surprisingly, it was detected in the abdomen by C-arm and was expelled uneventfully while defecating two days later.

Continuous positive airway pressure treatment for acute mountain sickness at 4240 m in the Nepal Himalaya.

Acute mountain sickness (AMS) is very common at altitudes above 2500 m. There are few treatment options in the field where electricity availability is limited, and medical assistance or oxygen is unavailable or difficult to access. Positive airway pressure has been used to treat AMS at 3800 m. We hypothesized that continuous positive airway pressure (CPAP) could be used under field conditions powered by small rechargeable batteries. Methods Part 1. 5 subjects trekked to 3500 m from 2800 m in one day and slept there for one night, ascending in the late afternoon to 3840 m, where they slept using CPAP 6-7 cm via mask. The next morning they descended to 3500 m, spent the day there, ascended in late afternoon to 3840 m, and slept the night without CPAP. Continuous overnight oximetry was recorded and the Lake Louise questionnaire for AMS administered both mornings. Methods Part 2. 14 trekkers with symptoms of AMS were recruited at 4240 m. All took acetazolamide. The Lake Louise questionnaire was administered, oximetry recorded, and CPAP 6-7 cm was applied for 10-15 min. CPAP was used overnight and oximetry recorded continuously. In the morning the Lake Louise questionnaire was administered, and oximetry recorded for 10-15 min. The equipment used in both parts was heated, humidified Respironics RemStar® machines powered by Novuscell™ rechargeable lithium ion batteries. Oximetry was recorded using Embletta™ PDS. Results Part 1. CPAP improved overnight Sao2 and eliminated AMS symptoms in the one subject who developed AMS. CPAP was used for 7-9 h and the machines operated for >8 h using the battery. Results Part 2. CPAP use improved Sao2 when used for 10-15 min at the time of recruitment and overnight CPAP use resulted in significantly reduced AMS symptoms. Conclusion. CPAP with rechargeable battery may be a useful treatment option for trekkers and climbers who develop AMS.
