RESUMO
INTRODUCTION: Most trauma societies recommend intubating trauma patients with Glasgow Coma Scale (GCS) scores ≤8 without robust supporting evidence. We examined the association between intubation and 30-d in-hospital mortality in trauma patients arriving with a GCS score ≤8 in an Indian trauma registry. METHODS: Outcomes of patients with a GCS score ≤8 who were intubated within 1 h of arrival (intubation group) were compared with those who were intubated later or not at all (nonintubation group) using various analytical approaches. The association was assessed in various subgroup and sensitivity analyses to identify any variability of the effect. RESULTS: Of 3476 patients who arrived with a GCS score ≤8, 1671 (48.1%) were intubated within 1 h. Overall, 1957 (56.3%) patients died, 947 (56.7%) in the intubation group and 1010 (56.0%) in the nonintubation group, with no significant difference in mortality (odds ratio = 1.2 [confidence interval, 0.8-1.8], P value = 0.467) in multivariable regression and propensity score-matched analysis. This result persisted across subgroup and sensitivity analyses. Patients intubated within an hour of arrival had longer durations of ventilation, intensive care unit stay, and hospital stay (P < 0.001). CONCLUSIONS: Intubation within an hour of arrival with a GCS score ≤8 after major trauma was not associated with differences in-hospital mortality. The indications and benefits of early intubation in these severely injured patients should be revisited to promote optimal resource utilization in LMICs.

This study aimed to investigate the risk factors associated with intracranial involvement in COVID-19-associated mucormycosis (CAM) and to develop a nomogram model for predicting the risk of intracranial involvement, with a specific focus on perineural spread. An ambispective analysis was conducted on 275 CAM patients who received comprehensive treatment. Univariable and multivariable logistic regression analyses were performed to identify independent risk factors, and a nomogram was created based on the results of the multivariable analysis. The performance of the nomogram was evaluated using a receiver operating characteristic (ROC) curve, and the discriminatory capacity was assessed using the area under the curve (AUC). The model's calibration was assessed through a calibration curve and the Hosmer Lemeshow test. In the results, the multivariable logistic regression analysis revealed that age (OR: 1.23, 95% CI 1.06-3.79), HbA1c (OR: 7.168, 95% CI 1.724-25.788), perineural spread (OR: 6.3, 95% CI 1.281-19.874), and the disease stage were independent risk factors for intracranial involvement in CAM. The developed nomogram demonstrated good discriminative capacity with an AUC of 0.821 (95% CI 0.713-0.909) as indicated by the ROC curve. The calibration curve showed that the nomogram was well-calibrated, and the Hosmer Lemeshow test yielded a P-value of 0.992, indicating a good fit for the model. In conclusion, this study found that CAM particularly exhibits perineural spread, which is a predictive factor for intracranial involvement. A nomogram model incorporating age, HbA1c, disease stage, and perineural spread was successfully developed for predicting intracranial involvement in CAM patients in both in-patient and out-patient settings.
Discovery of perineural spread in COVID-19-associated mucormycosis reveals a new predictive model for intracranial complications which is crucial for early intervention.

INTRODUCTION: Round window approach and cochleostomy approach can have different depth of electrode insertion during cochlear implantation which itself can alter the audiological outcomes in cochlear implant. OBJECTIVE: The current study was conducted to determine the difference in the depth of electrode insertion via cochleostomy and round widow approach when done serially in same temporal bone. METHODOLOGY: This is a cross-sectional study conducted in the Department of Otorhinolaryngology in conjunction with Department of Anatomy and Department of Diagnostic and Interventional Radiology over a period of 1 year. 12-electrode array insertion was performed via either approach (cochleostomy or round window) in the cadaveric temporal bone. HRCT temporal bone scan of the implanted temporal bone was done and depth of insertion and various cochlear parameters were calculated. RESULT: A total of 12 temporal bones were included for imaging analysis. The mean cochlear duct length was 32.892 mm; the alpha and beta angles were 58.175° and 8.350°, respectively. The mean angular depth of electrode insertion via round window was found to be 325.2° (SD = 150.5842) and via cochleostomy 327.350 (SD = 112.79) degree and the mean linear depth of electrode insertion via round window was found to be 18.80 (SD = 4.4962) mm via cochleostomy 19.650 (SD = 3.8087) mm, which was calculated using OTOPLAN 1.5.0 software. There was a statically significant difference in linear depth of insertion between round window and cochleostomy. Although the angular depth of insertion was higher in CS group, there was no statistically significant difference with round window type of insertion. CONCLUSION: The depth of electrode insertion is one of the parameters that influences the hearing outcome. Linear depth of electrode insertion was found to be more in case of cochleostomy compared to round window approach (p = 0.075) and difference in case of angular depth of electrode insertion existed but not significant (p = 0.529).

RESUMO
BACKGROUND: Invasive fungal sinusitis, particularly mucormycosis, presents a significant clinical challenge, especially in pediatric populations. This retrospective epidemiologic study aimed to investigate the clinical characteristics, risk factors and outcomes associated with this rare but severe condition, with a focus on orbital morbidity. METHODS: Clinical data of 12 pediatric patients diagnosed with invasive fungal sinusitis between 2021 and 2023 were retrospectively analyzed. Diagnosis involved microbiological and histopathologic examinations, alongside radiologic imaging. Treatment comprised surgical intervention and antifungal therapy, with a detailed evaluation of orbital involvement. Statistical analysis included descriptive statistics and logistic regression. RESULTS: Predominantly affecting males, the median age of the patients was 8 years. Common symptoms included orbital swelling and impaired vision. Imaging revealed characteristic features of invasive fungal sinusitis, including fat stranding and bone erosions. Orbital involvement was extensive, with poor visual outcomes observed in several cases. Surgical debridement and antifungal therapy, including transcutaneous retrobulbar Amphotericin B, were administered. Risk factors associated with poor orbital outcomes included duration of diabetes and glycated hemoglobin levels. Mortality rate stood at 22.2%. CONCLUSIONS: Early diagnosis, aggressive surgical intervention and combined antifungal therapy are essential for improving outcomes. Timely intervention showed stabilization of the orbital disease and better outcomes in pediatric patients. Further research with larger sample sizes is warranted to better understand and address this serious condition.

Coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM) has emerged as a formidable infection in patients with COVID-19, this study was designed to assess the QOL in patients with and its predictability for survival in CAM victims. This long term prospective observational study of 290 patients with CAM was conducted over 2 years using a standard questionnaire (the abbreviated World Health Organization Quality of Life questionnaire [WHO-BREF]), Karnofsky performance scale (KPS), palliative performance scale (PPS) and patient rated improvement (PRI) ranging from 0 to 9. Cut-off values of ≤ median score was considered to indicate poor QOL or poor improvement. The overall 2 year survival rate was 78.27% with mean survival time of 763.2 ± 1.2 days (Mean ± S.E) (95% CI: 760.76-765.6). The disease specific mortality was 22.1%. The overall mean QOL was 53.5(10.2) with 51% of population exhibiting poor QOL. Spearman rho correlation showed strong positive correlation between the three QOL scales and PRI (ρ-0.72, p < 0.001). On Cox regression analysis the stage, all four domains of WHO BREF, KPS, and PPS were independent predictors of long term survival in CAM patients. Approximately half of the patients with CAM had poor QOL and poor improvement. All 4 domains of WHO BREF score can be used as a predictor of long term survival in CAM patients. Early recognition is the key to optimal treatment, improved outcomes, and improved QOL in patients with CAM.
RESUMO
OBJECTIVE: This study aims to discern the disparities in the electrode-to-modiolus distance (EMD) between cochleostomy and round window approaches when performed sequentially in the same temporal bone. Additionally, the study seeks to identify the cochlear metrics that contribute to these differences. METHODOLOGY: A cross-sectional study was conducted, involving the sequential insertion of a 12-electrode array through both round window and cochleostomy approaches in cadaveric temporal bones. Postimplantation high-resolution CT scans were employed to calculate various parameters. RESULTS: A total of 12 temporal bones were included in the imaging analysis, revealing a mean cochlear duct length of 32.892 mm. The EMD demonstrated a gradual increase from electrode 1 (C1) in the apex (1.9 ± 0.07 mm; n = 24) to electrode 12 (C12) in the basal turn (4.6 ± 0.24 mm; n = 12; p < 0.01). Significantly higher EMD values were observed in the cochleostomy group. Correlation analysis indicated a strong positive correlation between EMD and cochlear perimeter (CP) (rs = 0.64; n = 12; p = 0.03) and a strong negative correlation with the depth of insertion (DOI) in both the middle and basal turns (rs = - 0.78; n = 20; p < 0.01). Additionally, EMD showed a strong negative correlation with the DOI-CP ratio (rs = -0.81; n = 12; p < 0.01). CONCLUSION: The cochleostomy group exhibited a significantly higher EMD compared with the round window group. The strong negative correlation between EMD and DOI-CP ratio suggests that in larger cochleae with shallower insertions, EMD is greater than in smaller cochleae with deeper insertions.

RESUMO
Background: Secondary bacterial infections during COVID-19 hospitalization have been reported in about 6-15% of patients. Aims: To study the secondary bacterial infections that affected the COVID-19 patients during their hospitalisation and to unearth the bacteriological profile of samples obtained after their demise. Settings and Design: This prospective study was carried out at a COVID-19 dedicated, apex tertiary care centre in North India from July 2020 to April 2021. Methods and Materials: Samples of 268 patients were considered for the study. Nasopharyngeal swab specimen, blood, and tissue (lung) were collected from the deceased body as early as possible and processed. Statistical Analysis: Statistical analyses were performed using STATA version 11.1 (Stata Corp., College Station, TX, USA). Results: A total of 170 samples were received from patients before their death, which included blood, urine, respiratory samples, pus, and cerebrospinal fluid. Forty-four pathogens were isolated, which consisted of Acinetobacter baumannii (43.1%), Klebsiella pneumoniae (36.3%), Escherichia coli (11.3%), and Pseudomonas aeruginosa (4.5%), Enterococcus faecium (4.5%). Two hundred fifty-eight samples were collected from the deceased bodies wherein the nasopharyngeal sample was highest, followed by tissue and blood. A total of 43 pathogens were isolated among them which included A. baumannii (44.1%), followed by K. pneumoniae (25.5%), E. coli (20.9%), P. aeruginosa (6.97%) and Enterobacter cloacae (2.3%). All these isolates were highly resistant to antimicrobials. Conclusions: In our study, bacterial profiles in antemortem and postmortem samples were found to be similar, suggesting that resistant pathogens may be the cause of mortality in COVID-19 infected hospitalised patients.

Background: Ventilator-associated pneumonia (VAP) is a major cause of morbidity and mortality in patients receiving mechanical ventilation in India. Surveillance of VAP is essential to implement data-based preventive measures. Implementation of ventilator-associated events (VAE) criteria for surveillance has major constraints for low resource settings, which can lead to significant underreporting. Surveillance of VAP using common protocols in a large network of hospitals would give meaningful estimates of the burden of VAP in low resource settings. This study leverages a previously established healthcare-associated infections (HAI) surveillance network to develop and test a modified VAP definition adjusted for Indian settings. Methods: In this observational pilot study, thirteen hospitals from the existing HAI surveillance network were selected for developing and testing a modified VAP definition between February 2021 and April 2023. The criteria used for diagnosing VAP were adapted from the CDC's Pediatric VAP definition and modified to cater to the needs of Indian hospitals. Designated nurses recorded each VAP event in a case report form (CRF) and also collected denominator data. The data was entered into an indigenously developed database for validation and analysis. At the time of data analysis, a questionnaire was sent to sites to get feedback on the performance of the modified VAP definitions. Findings: Out of 133,445 patient days and 40,533 ventilator days, 261 VAP events were recorded, with an overall VAP rate of 6.4 per 1000 ventilator days and a device utilization ratio (DUR) of 0.3. A total of 344 organisms were reported from the VAP events. Of these, Acinetobacter spp (29.6%, 102) was the most frequent, followed by Klebsiella spp (26.7%, 92). Isolates of Acinetobacter spp (98%) and Enterobacterales (85.5%) showed very high resistance against Carbapenem. Colistin resistance was observed in 6% of Enterobacterales and 3.2% of Acinetobacter spp. Interpretation: Data from this pilot study needs to validated in the larger Indian HAI surveillance network so that it can help in wider implementation of this protocol in order to assess its applicability p VAP across India. Funding: This work was supported by a grant received from the Indian Council of Medical Research (code I-1203).
RESUMO
Background and Aims: There are two approaches for ultrasound (US)-guided vessel cannulation: the short axis (SA) approach and the long axis (LA) approach. However, it remains to be seen which approach is better. Therefore, we performed the present updated systematic review and meta-analysis to assess the effectiveness and safety of US-guided vascular cannulation between the SA and LA techniques. Methods: We performed a comprehensive electronic database search in PubMed, Embase, Cochrane Library and Web of Science for the relevant studies from inception to June 2022. Randomised controlled trials comparing the SA approach and the LA approach for US-guided vascular access were incorporated in this updated meta-analysis. The first-attempt success rate was the primary outcome. The secondary outcomes were the overall success rate, cannulation time, number of attempts and the incidence of complications. The statistical analysis was conducted using RevMan software (version 5.4; the Nordic Cochrane Centre, the Cochrane Collaboration, Copenhagen, Denmark). The Cochrane risk of bias tool was used to evaluate each study's potential risk for bias. Results: In total, 16 studies consisting of 1885 participants were incorporated in this updated meta-analysis. No statistically significant difference was found between the SA and LA vascular access techniques for first-pass success rate (risk ratio = 1.07, 95% confidence interval: 0.94-1.22). The overall cannulation success rate, complication rate, average cannulation time and average number of attempts were not significantly different between the SA and LA groups. Conclusion: This updated meta-analysis demonstrated that the SA and LA approaches of US-guided vessel cannulation are similar regarding first-pass success, overall cannulation success rate, total complication rate, cannulation time and the number of attempts.
RESUMO
Ameloblastoma is the most common aggressive benign odontogenic tumour of the jaws. Ameloblastoma is a benign epithelial odontogenic tumour that typically arises in the mandible or maxilla. A clinical, radiographic and histopathological report is presented of a case of giant acanthomatous ameloblastoma in the left hemi mandible of a 46-year-old healthy lady. The histopathological examination of the removed specimen revealed the histopathological pattern of an acanthomatous ameloblastoma. The radiographic appearance of the lesion showed the presence of multilocular radiolucencies, which were crossing the midline, which is rarely found in ameloblastoma. Due to its rarity and lack of data, we take this opportunity to present a case of advanced acanthomatous ameloblastoma and its surgical challenges.
RESUMO
Purpose: A videolaryngoscope has been recommended for intubation in the COVID-19 scenario but the videolaryngoscope providing optimal intubation conditions is not ascertained. We compared KingVision channelled blade with a non-Channelled videolaryngoscope for intubation times in a simulated COVID-19 intubation scenario by both anaesthesiologists and non-anaesthesiologists. Methods: This prospective randomised cross over mannequin study was conducted in a skill training lab. 25 anaesthesiologists and 25 non-anaesthesiologists donned in standard personal protective equipment performed 100 intubations with KingVision and Tuoren videolaryngoscopes in a mannequin covered with a transparent plastic sheet. The total intubation time, percentage of glottic opening scores, first attempt success rates were assessed. Results: The mean difference in intubation times in anaesthesiologists and non-anaesthesiologist less with KingVision videolaryngoscope (21.1s; 95% CI 9.6-32.6s vs. 35.9s; 95% CI 24.4-47.4 s; P = 0.001). Percentage of glottic opening score was significantly better with KingVision by non-anaesthesiologists (60; IQR 42.5 to 75 vs. 70; IQR 50 to 100; P = 0.019). KingVision provided superior first attempt success rate in non-anaesthesiologists (84% vs. 61.9%; P = 0.02) and anaesthesiologists (96% vs. 76%; P = 0.12). Conclusion: KingVision channelled videolaryngoscope provided faster intubation times, glottic views and first attempt success rates in a simulated COVID-19 scenario in manikins and might be preferred over videolaryngoscopes with non-channelled blade. The findings need to be further verified in humans. Trial registration: ctri.nic.in identifier: REF/2020/05/033338.
RESUMO
Abstract Introduction Airway foreign bodies are emergencies involving multidisciplinary departments like Pediatrics, Aneasthesiology and Otorhinolaryngology. It is always a challenge to diagnose and manage patients who present late to our emergencies. Objective In the present study, we aim to analyze the various challenges faced during the management of tracheobronchial foreign bodies with delayed presentation. Methods A retrospective hospital record-based analysis of patients who presented to us with tracheobronchial foreign bodies from January 2017 to February 2020 was performed. All patients until the age of 16 years old were included in the present study. We assessed the demographics, preoperative, intraoperative and postoperative data of the patients. Results Seventeen patients were analyzed in the study. Among these, 44.4% of the patients had delayed presentation (> 1 month). The majority of the patients had an organic foreign body (Supari or betel nut). All patients underwent rigid bronchoscopy, followed by optical forceps-assisted removal of the foreign body. A total of 82% of the patients had granulations around the foreign body. Conclusion Management of delayed presentation tracheobronchial foreign body is a big challenge for Otorhinolaryngologists. The key factors for preventing complications in the definitive management of tracheobronchial foreign bodies are preoperative planning, multi-discipline teamwork, surgeon expertise and technique.
