Development of Digit in Noise Test in Hindi.

BACKGROUND: The digit in the noise test is a simple hearing screening tool that can identify hearing loss at the early stage. This screening tool takes less time than traditional pure-tone audiometry. There is a scarcity of hearing health professionals with few resources for carrying out hearing screening on a large scale in India. Hence, a hearing screening tool for the Hindi-speaking population is needed. AIM AND OBJECTIVE: The study aimed to develop and validate the Digit in Noise test in Hindi (DIN-H). METHODS: A native Hindi female speaker recorded single digits from 1 to 9 made into triplet combinations, which were binaurally presented to 20 normal hearing subjects having hearing thresholds less than 25 dBHL from 250 to 8000 Hz in the presence of broadband speech-shaped noise. The digit triplets were homogenized using speech intelligibility function for similar difficulty levels across stimuli. The homogenized stimuli were evaluated by obtaining the Speech Recognition Threshold (SRT) of 20 normal hearing subjects. RESULTS: The Mean SRT was - 10.4 and - 11.3 dB before and after homogenization. A strong positive correlation existed between test and retest SRTs (0.78). Mean SRT and slope obtained before and after optimization were comparable to other languages like Korean and English. This test can act as a reliable screening tool for assessing individuals. The test was administered to 106 normal hearing participants. The 95th percentile of the SRT value obtained was - 5.6 dB, which was kept as a cut-off score for the screening test. CONCLUSION: DIN-H can be used as a screening tool for assessing the integrity of the auditory system on a large scale in less time for the Hindi-speaking population.

The Role of Trans Oral Robotic Surgery in the Carcinoma of Unknown Primary: A New Evidence in the Horizon?

The detection of the primary site in Carcinoma of Unknown Primary (CUP) is a challenging task which can significantly alter the course of management and also prognosis. Various modalities have been assessed with varying sensitivity and specificity. Imaging and cytological diagnosis have formed a key part of the diagnostic algorithm of CUP. Trans Oral Robotic Surgery offers the advantage of being both diagnostic as well as therapeutic with promising sensitivity and specificity and can form an integral part in the management of CUP. A prospective study was carried out at a tertiary care centre over a period of one year. Patients with unilateral neck swelling which was histopathologically proven squamous cell carcinoma neck metastasis were included in the study. They were evaluated with endoscopy and radiology according to the standard algorithm. When these failed to detect the primary, the patients underwent ipsilateral radical tonsillectomy and tongue base mucosal wedge biopsy via TORS. Post-operative histopathological examination was done on the resected specimens to detect the primary site. Transoral Robotic Surgery was able to localise primary in 50% of the patients enrolled in the study. Out of the primary site identified by TORS; 55.56% were located in the tonsil and 44.4% in the tongue base. TORS can offer promising detection rates of the occult primary in CUP and should form an integral part of the diagnostic algorithm.

An Easy to use Periosteal Flap for Cochlear Implantation: Experience from a Tertiary Care Centre.

This report describes a novel and easy periosteal flap design for cochlear implantation. This technique has been used in 37 patients between June 2019 and August 2020. The patients have been followed up for a period of 2 months to 15 months. There were no flap related complications attributed to this flap. There was no wound hematoma, wound breakdown or implant migration. The flap design is safe, easy, less time consuming and results in better coverage of the receiver stimulator unit without any tension.

Factors influencing radial artery occlusion after transradial coronary intervention in the Indian population.

OBJECTIVE: Radial artery occlusion (RAO) is a common complication during transradial coronary intervention. Its incidence is variably reported in literature and its predictors are not completely understood. In this study, we aimed to define the incidence and factors influencing RAO in patients undergoing transradial coronary intervention. METHODS: This was a single-center prospective study (October 2018 to September 2019) that enrolled 1,754 patients who were evaluated for RAO 24 hours after transradial coronary intervention. Univariate as well as multivariate analyses were done to identify patient and procedure related factors predicting the occurrence of RAO. RESULTS: A total of 1,374 patients (78.3%) underwent angioplasty, whereas 380 (21.7%) underwent angiography alone. RAO was diagnosed in 11.97% patients. Lower glomerular filtration rate, multiple puncture attempts for radial artery access, larger sheath size, complex nature of interventional procedure, longer homeostasis time, and forearm hematoma formation were independent predictors for RAO. CONCLUSION: RAO was not an uncommon complication in transradial coronary interventions, especially in the Indian population; and the knowledge of predictors may be helpful in its prevention.

Asthma and Fungus: Role in Allergic Bronchopulmonary Aspergillosis (ABPA) and Other Conditions.

Asthma is an allergic, respiratory disorder characterized by hyper responsiveness of the airway to external stimuli. Considerable research is currently being directed towards understanding the role of environmental and genetic factors contributing to the development of asthma and its severity. Recent years have seen a substantial rise in evidence linking fungi to asthma. Few major clinical conditions associated with fungal sensitization and hypersensitive immune response are Allergic bronchopulmonary aspergillosis (ABPA), Allergic fungal rhinosinusitis (AFRS) and Severe asthma with fungal sensitization (SAFS). The most common fungi implicated in these conditions belong to genus Aspergillus, although an association with several other fungi has been described. In this review authors discuss the varying clinical characteristics of fungus induced respiratory complications in individuals with asthma. They also highlight the epidemiology of these conditions including their prevalence in children and their fungal etiological profile. Laboratory diagnostic methods and clinical case definitions have also been discussed. Future studies evaluating the role of fungal exposure and susceptibility to asthma are required. Till date there are no guidelines for the diagnosis and treatment of ABPA in pediatric population, thus it is also imperative to establish validated clinical definitions of fungal allergic manifestations in pediatric patients with asthma to fully understand this complex interaction.
