Association of socio-demographic factors with clinical outcome among hospitalized patients in first and second waves of COVID-19 pandemic: Study from the developing world.

Background: Recent disease resurgence in China indicates that corona virus infectious disease is still a pertinent public health problem. We stand at a juncture where we are still unsure about the initial dilemmas regarding its birth, therapies, and the emerging novel strains. Medical literature has focused on the clinical, laboratory, radiological, and therapeutic aspects of disease management. There is paucity of literature on the association between socio-demographic variables on disease severity and clinical outcome. Materials and Methods: This retrospective observational study analyzing the socio-demographic variables was performed at a dedicated COVID care center in western Maharashtra, India. Electronic records of all individuals who were admitted to this hospital from July 29 2020, to June 14, 2021, and diagnosed COVID-19 positive by reverse transcriptase polymerase chain reaction (RT-PCR) were identified after due institutional ethical clearance. Patients admitted from July 29, 2020, to February 27, 2021, were categorized as patients presenting during the 'first wave of viral pandemic'. Those admitted from March 01, 2021, to June 14, 2021, have been included as patients admitted during 'second wave of viral pandemic'. The following outcome parameters were collected (presenting symptoms, duration of symptoms before the individual presented for diagnostic RT-PCR, total duration of symptoms, severity of disease at onset, duration of hospital stay, the final outcome (discharge/death) and Charlson's comorbidity index). The linear regression model was used to establish association between socio-demographic factors and disease severity at onset (mild/moderate/severe/critical). Results: A total of 37033 patients were screened, and the positivity rate with RT-PCR was 16.99% (n = 6275) during the study period. Out of which 45% (n = 2824) of the patients had mild disease requiring home isolation and the remaining 55% of patients required admission. 1590 patients from the first wave and 910 from the second wave of COVID-19 were hospitalized and included in the study after exclusion. The mean age of patients in first wave was 49 years and that in second wave was 54 years with 77.6% and 70.6% males in two waves, respectively. The burden of critical cases was higher in second wave as computed to first wave (10% vs 8%). The second wave had more outreach in the rural population as compared to second one (17.8% vs 12.2%). The mean duration from the onset of symptoms to hospitalization was 03 and 04 days, respectively, in two waves. Mortality associated in two waves was 11.9% and 24%, respectively (P < 0.05). Higher Charlson's comorbidity index was associated with higher mortality, and the cumulative survival from urban area was more as compared to the rural population (log rank - 9.148, P = 0.0002). Conclusion: The second COVID-19 wave had significantly higher case mortality. It affected elderly patients and those with rural background. The factors associated with higher mortality during COVID-19 pandemic were rural background, higher Charlson's comorbidity index and late presentation to the hospital. Ongoing vaccine campaigns, thus, should focus on rural areas and individuals with comorbidities especially in developing and least developed countries.

Role of Pre-Operative High-Resolution Computed Tomography for Surgical Planning in Patients Undergoing Cochlear Implantation - An Observational Study.

Background: Currently preoperative magnetic resonance imaging (MRI) brain and High-Resolution Computed Tomography (HRCT) scanning of temporal bones form part of routine Cochlear implantation (CI) assessment. Pre- operative imaging demonstrates anatomic details or anomalies if any, that prove essential in pre-surgical evaluation of patients. These form a road map for the surgeon to anticipate any difficulty during surgery, to aid in decision making to implant the most appropriate ear, plan surgical technique, or select electrode arrays. Methods: A descriptive observational pilot study was conducted at tertiary care hospital involving 51 paediatric patients worked-up for CI. Patients after detailed clinical evaluation and MRI Brain, a tentative surgical plan was formulated by a candidacy CI screening committee. Patients selected for surgery underwent HRCT temporal bones and surgical plan was modified after analysing the same. Percentage of cases in which surgical plan changed (in terms of laterality of surgery) after correlating with HRCT findings were determined and data analysed. Results: A total of 51 patients worked up for CI were included in the study. In 37.3% cases, there were unfavourable MRI findings. HRCT scan was used to aid the surgical road map in these patients, which based on MRI findings would have had suboptimal outcome. Conclusion: With this understanding, we recommend that, MRI with precise interpretation would be sufficient to furnish all necessary information in preoperative assessment of CI patients, and a HRCT temporal bones maybe indicated only in difficult cases or those with unfavourable MRI findings, may aid predict surgical events.

Evaluation of surgical skill among otology residents during cadaveric temporal bone dissection using an objective assessment tool.

Background: The acquisition and refinement of technical skills by the surgical residents are central to surgical teaching; hence, there is increasing interest in the objective assessment of surgical competence. In the field of otology, as of now, there are limited studies for the assessment of surgical competence, also, various subjective methods are being used to assess this vital aspect of training. This study aimed to validate and use an objective assessment tool for the valuation of surgical skills in a tertiary care teaching institute in the Indian subcontinent. Methods: Surgical competence of the residents in temporal bone dissection was assessed on a Likert scale by using a grading scale developed by Wan et al., after obtaining necessary permissions. Results: Junior residents in ENT who had completed one year of residency in otolaryngology were asked to perform temporal bone surgery (cortical mastoidectomy) and were marked according to the proforma by two senior experienced otologists. The Cronbach's alpha value was .86 which is an indicator of good technical validity. Conclusions: In our study, we have validated a grading scoring scale used by Wan et al. to objectively assess the ability of an otology resident to perform temporal bone surgery. It is recommended for use in Indian scenario due to its good technical validity. The use of a Likert scale to individually rate each competency makes the evaluation precise and simple.

A comparison of the efficacy of narrow band imaging and contact endoscopy in an early diagnosis of squamous malignancies of the upper aerodigestive tract.

Background: This study aims to compare the efficacy of narrow band imaging (NBI) endoscopy and contact endoscopy in early diagnosis of squamous malignancies of upper aerodigestive tract. Methods: This study was of 18 months duration, sample size 50, and carried out at tertiary care hospital. The patients were subjected initially to NBI endoscopy followed by contact endoscopy. Thereafter, the lesion was biopsied and subjected to histopathological examination as is done routinely. The images obtained were analyzed based on criteria proposed by earlier studies and compared with histopathological examination as gold standard. Results: The sensitivity, specificity, and negative predictive values of NBI in early diagnosis of squamous malignancies of upper aerodigestive tract were high and better than contact endoscopy. Conclusion: Endoscopic NBI is a noninvasive and promising tool used for in vivo differentiation between malignant and nonmalignant lesions of upper aerodigestive tract by using morphology of mucosal capillaries and is more efficacious than contact endoscopy. It can be employed as part of routine ENT examination in outpatient departments; however, it has got a learning curve associated with it.

Ossifying Fibroma: A Case Report of an Unusual Presentation of Angiodysplastic Disease with Review of Literature.

Ossifying fibroma is a nonneoplastic developmental disease of osseous tissue seen rarely in association with Sturge-Weber syndrome. It is a lesion of unknown aetiology, uncertain pathogenesis, and diverse histopathology. The aim of this study is to report an unusual case of in a 11-year-old male of SWS. The rarity of the case and the fact that ossifying fibroma may be associated with Sturge-Weber syndrome propelled us to report it. Physical examination showed facial asymmetry (due to hemifacial swelling) without any tenderness, fluctuation, ocular pain, or ophthalmoplegia. Imaging studies revealed a solid mass involving the left maxilla and orbital floor. A conservative therapeutic approach to these lesions may be sufficient to relieve signs and symptoms effectively. Periodic follow-up is indicated to detect recurrences or malignant changes in the early stages.

Complications of Acute Bacterial Rhinosinusitis in Contemporary Practice: Lessons Learnt and the Way Ahead.

There are variable presentations of complications of rhinosinusitis, which may be subtle especially due to use of antibiotics. Thus the classical picture as described by Chandler is rarely seen and threshold for diagnosing and treating a complication should be low. To identify possible risk factors for development of complications in acute bacterial rhinosinusitis (ABRS) and suggest a new method of reporting/classifying the complications. We conducted a retrospective study and observed the clinical presentation and risk factors of 9 patients who presented with complications of ABRS in our OPD during a period of 6 years, and then tried to formulate a reporting method based on the risk factors. We identified certain risk factors which include age, gender, sinus involved, extension beyond sinus, history of trauma, anatomical variations, and duration of symptoms. There are possible risk factors for development of complications. These factors can be studied in further details to ascertain their causal relationship in causing these complications. We also suggest a new method of reporting the complications. Such a reporting system would help in accurately identifying the exact severity of the disease, prognosticating the disease and guide treatment.

Comparison of Intraoperative Neural Response Telemetry Results and Postoperative Neural Response Telemetry Results in Case of Children with Congenital Bilateral Severe to Profound Sensorineural Hearing Loss Undergoing Single Sided Cochlear Implantation.

Aim and Objectives: This study is designed to compare the Intra Operative Neural Response Telemetry (NRT) results with Post-Operative NRT results of the cochlear implanted children, to assess the importance of Intra Operative NRT thresholds in device activation and/or switch on of the audio processor and to evaluate the importance of Intra and post operative AutoNRT results in predicting behavioural thresholds during mapping of prelingual Cochlear Implanted children. Materials and methods: A total of thirty (30) children (16 boys, 14 girls) with congenital Bilateral (B/L) severe to profound Sensorineural hearing loss (SNHL) were included in this study. Children between the age range of 12 to 60 months were participated in this study. All the participants were implanted with Nucleus 24 cochlear implant system. In each patient, the intra operative NRT-thresholds were measured for all 22 active electrodes. Then Intra Operative NRT thresholds were correlated with Post-Operative NRT thresholds at the time of switch on and the behavioural map after six months of switch on of the device (Audio Processor). Results: There is a significant enhancement observed in thresholds of postoperative NRT responses which were raised or absent during intraoperative session. There is a gain in NRT thresholds marked after 6 months of postoperative follow up in comparison with first measurement at the time of Switch On of the device but the change not that significant. During postoperative mapping, there was a significant positive correlation noticed between neural response telemetry level measurements and behavioural threshold level. Conclusion: Absent or elevated NRT responses during intraoperative testing for some electrodes especially basal electrodes does not mean that electrode is out of order or outside the cochlea, because an improvement in NRT thresholds usually occurs postoperatively. In case of children with congenital B/L severe to profound SNHL, the NRT values have a very useful role in predicting the behavioural thresholds. Combination of NRT values with behavioural thresholds and observations of Auditory Verbal Therapist can help in providing best suitable Map to the recipient.

Different Approaches to the Overlapping Infratemporal Fossa and Parapharyngeal Spaces: a Case Series and Review of Literature.

Parapharyngeal space and infratemporal fossa are 2 overlapping spaces in head and neck which have complex anatomy with vital neurovascular structures passing through them. Tumors of this region are extremely rare but majority of them (80%) are benign. Benign tumors of this region can lead to swellings in facial region, neck and oropharynx. Dysphagia may be a complaint of the patient. Many of these tumors have malignant potential. Removal of these tumors requires a good understanding of the anatomy of this space so that correct surgical approach can be selected. The surgeon needs to be adept in using the most suitable surgical approach for excision of these tumors. There are various approaches which can be used to access these deeply seated tumors but the issue of prime importance is selecting the appropriate approach for the various tumors here based on their size and their exact location in this complex anatomical space. Inappropriate approach can lead to inadequate tumor excision and can lead to injuries to the neurovascular structures in this region which can cause significant disability. The case series reported here describes the various approaches to this region and highlights the importance of correct selection of the surgical approach.

Laryngeal Trauma Managed with Titanium Mesh Fixation: A Rare Case Report.

Laryngeal fractures are though uncommon they can be potentially life threatening. Comminuted laryngeal cartilage fractures are difficult to manage and various fixation techniques have been described in literature. Outcome results of fixation with different materials can be varied. We report a case of 27 years old male who sustained laryngeal cartilage fracture following accidental fall. Patient underwent emergency tracheostomy and early surgical repair of fractured laryngeal thyroid cartilage with one of the newest techniques "titanium mesh fixation". After a month of surgery tracheostomy tube was removed and patient recovered with good laryngeal function. Titanium mesh fixation gave immediate effective fixation and stability to laryngeal fracture leading to good surgical outcome.

Dermoid Cyst Floor of Mouth: A Diagnostic Conundrum.

Dermoid cysts are benign tumours of ectodermal origin, commonly seen in young. The clinico-radiological presentation of dermoids can be equivocal, like in our case of a teenager who had painless swelling of floor of mouth. Radiological findings were consistent with cystic lesion but histopathological examination proved it as dermoid cyst.

Enigma of otologic immunoglobulin G4-related disease, COVID-19, and uncontrolled diabetes: The unholy trinity.

Otologic immunoglobulin G4-related disease (IgG4-RD) is a rare and a relatively newer pathology. COVID-19, IgG4-RD, and type 2 diabetes, all have independent capabilities to considerably affect the immune system. The immunological effects of COVID are a global conundrum; consequently, the association of this trio (otologic IgG4-RD, COVID-19, and type 2 diabetes), the only reported case in literature, paves the way for a fascinating interplay to explore the knowledge of which would help optimize treatment and improve disease outcomes.

The Effect of Environmental Noise on Consonant Perception in Individual With Normal Hearing: A Prospective Observational Study.

This study was done to identify the effect that environmental noises have on consonant perception of individuals with normal hearing sensitivity. The objectives were to find out the effect of white noise and environmental noises on consonant identification and to find the effect of noises on consonant features. Adult with normal hearing in both ears whose mother tongue was Odia were included. Initially the participants underwent pure tone audiometry, speech audiometry, immittance audiometry to confirm their normal hearing, good speech identification scores and normal middle ear function. For consonant identification test, the presentation level was 40 dB sensation level with reference to speech recognition threshold for all subjects. Consonant identification test was carried out in white noise and real environmental noises (traffic noise, classroom noise, park noise, restaurant noise) at 0 dB signal to noise ratio (SNR) and at + 5 dB (SNR). The results showed that at + 5 dB SNR condition all subjects were able to get 80% and above consonant identification (CI) scores irrespective of type of noise used for stimulus while at 0 dB SNR, the mean scores ranged from 75.5% (restaurant noise) to 84% (traffic noise). At + 5 dB SNR only in restaurant noise the CI scores were low as compared to those in white noise. At 0 dB SNR, the scores were low for both the test conditions of park noise and that of restaurant noise. Different types of noisy environments can affect consonant perception which can affect speech intelligibility.

An Observational Study to Compare Prevalence and Demography of Sensorineural Hearing Loss Among Military Personnel and Civilian Population.

To evaluate the pattern of sensorineural hearing loss (SNHL) in patients attending ENT OPD in a military setup as well as to compare the incidence of hearing loss in Military Personnel with civilian population. This observational cross sectional comparative study was conducted over a period of April 2018 to July 2019. A total of 300 patients with hearing loss (HL) were included. Demographic characteristics along with laterality of sensorineural hearing impairment were compared between military personnel and civilians. Data was statistically compared between civilians and military personnel. A P-value of < 0.05 was considered statistically significant. We report an overall prevalence of 3.78% SNHL in the ENT OPD. Specifically the prevalence of SNHL among military personnel was 2.17% and in civilian population was 4.83% (P < 0.0001). The mean age of the military personnel was significantly less than civilians (62.53 ± 10.03 vs 65.98 ± 12.46, P = 0.003). There were 68% Males and 32% females. Significantly higher number of males were present in military group as all participants were males (100% vs 58.62%, P < 0.0001). There was no significant difference in the laterality of SNHL between Military personnel and the civilian population with bilateral involvement being common in both populations. It can be concluded that bilateral SNHL type is the most common type of hearing impairment among military personnel as well as civilians complaining of HL. Males of 51-70 years are most affected with SNHL.

Evaluation of physicochemical and biological properties of nonreconstituted MYL-1401O vials, reconstituted MYL-1401O suspension in vial, and diluted MYL-1401O suspension in infusion bags (0.9% saline) for extended duration.

BACKGROUND: MYL-1401O; trastuzumab-dkst (Ogivri™; Mylan Inc.) is a biosimilar to the trastuzumab reference product (Herceptin®; Genentech, USA). Assessment of physicochemical stability and biological activity for the non-reconstituted, reconstituted, and infused solution over an extended, clinically relevant duration is critical for ensuring optimal patient outcomes and health resource utilization. METHODS: The physicochemical and biological stability of MYL-1401O was assessed in non-reconstituted vials stored at 25 °C ± 2 °C/60% ± 5% relative humidity (RH) for 6 months, reconstituted 21 mg/mL solution in vials stored at 2 °C to 8 °C for 10 days, and diluted in 0.9% saline-containing infusion bags at 0.3 mg/mL and 4.0 mg/mL stored for 77 days at 2 °C to 8 °C, plus an additional 2 days at 25 °C ± 2 °C/60% ± 5% RH. RESULTS: At all storage conditions tested, MYL-1401O was physicochemically and biologically stable for extended duration and under various temperature and humidity conditions. CONCLUSIONS: MYL-1401O retained its physicochemical and biological stability under different storage conditions, which supports advanced preparation of MYL-1401O, better efficiency, less wastage, and cost-savings for better patient management.

Role of Octreotide in Conservative Management of Chyle Leak Post Neck Dissection in Cases of Head Neck Cancer: A Retrospective Analysis.

Chyle leak is a dreadful complication in patients undergoing neck dissections. Octreotide has been used in the management of chyle leak post neck dissections in head and neck cancer patients. Currently there is no consensus and practice guidelines on the same. (1) To study the role of octreotide in early cessation of post neck dissection chyle leak. (2) To study incidence of intra-operative and post-operative CL, its relation to the extent of nodal disease and neck dissection, prior radiotherapy. Retrospective analysis of 16 patients out of 529 neck dissection over a period of 03 years between Jan 2016 and Dec 2019 who developed post-operative chyle leak. All patients who had post-operative chyle leak were administered octreotide. Time taken for chyle leak to stop was primary outcome. Secondary outcomes were duration of hospitalization post-operatively, incidence of intra-operative and post-operative chyle leak, its relation to the extent of nodal disease, prior radiotherapy and type of neck dissection. 59 of 529 neck dissections (11.15%) were noted to have intra-operative chyle leak. 16 of 529 neck dissections (3.02%) developed post-operative chyle leak. On applying chi square test, prior multimodality and N plus neck were found to be significant risk factors in developing postoperative chyle leak. Considering only RT versus no RT in prior multimodality treated group, the difference was insignificant. Onset of chyle leak varied from 1 to 5 post-op day (mean 2.68 days). 15 (93.75%) patients responded to octreotide. Chyle leak resolved between 3 and 10 days (mean 5.18 days) and octreotide was given for 5-12 days (mean-7.18 days). Overall duration of hospitalization ranged from 09 to 18 days (mean 12.18 days). 01 patient (6.25%) had to be re-explored due to high volume leak despite using octreotide. Adverse effects of octreotide were minimal and tolerable. Octreotide is effective in reducing the duration of chyle leak, hospital stay and need for surgical intervention. It may be considered as suitable adjunct to conservative measures in the management for post-operative chyle leak.

Assessment of Level of Patient Satisfaction with Day-Care Surgery: An Observational Study.

To assess the level of patient satisfaction with day-care surgery at a tertiary care centre and to find out the different determinants that influence the patient satisfaction. Observational study; Tertiary care hospital in Western India; Patients undergoing Day-care surgery at Dept of ENT from Feb 2018 to Aug 2018; All patients who underwent day-care surgery were given a questionnaire to determine level of satisfaction. On analysis of data according to questions the average score was in the range of 3.5 to 4.22 out of a maximum score of 5. On analysis of data according to domains of patient care the scores ranged from 3.61 to 4.19. Although patients were generally satisfied with the level of care being provided to them there is still scope of improvement.

Management outcomes of mucormycosis in COVID-19 patients: A preliminary report from a tertiary care hospital.

BACKGROUND: Coronavirus disease 2019 (COVID-19) continues to be a significant health problem worldwide. The unprecedented surge of mucormycosis in patients with COVID-19 is a new emerging challenge. Although a few studies documenting high incidence of mucormycosis in COVID -19 patients have recently emerged in literature, data pertaining to treatment outcomes in such cohorts is lacking. Here, we report our experience in management of mucormycosis in COVID-19 patients at our tertiary care centre. METHOD: The clinical, imaging, histopathological and treatment data of 20 patients with mucormycosis (in setting of COVID-19) was analysed. RESULTS: 35% and 65 % of cases developed mucormycosis in setting of active and recovered COVID-19 infections respectively. Diabetes mellitus was documented in 80% cases, with 55% demonstrating HbA1c >10%. Steroid was administered in 80% during COVID-19 illness. Imaging demonstrated paranasal sinus (PNS), orbital and intracranial extension in 100%, 55% and 20% patients respectively. All received amphotericin and underwent endoscopic debridement, 20% underwent orbital decompression and 5% maxillectomy with orbital exenteration. 6/20(30%) patients died (4 with rhino-orbito-cerebral disease, 1 with extensive orbito-maxillary involvement and 1 sino-nasal disease). All 6 patients received steroids and documented poor glycaemic control. CONCLUSION: The strong association of hyperglycemia and steroid intake with mucormycosis in COVID-19 cases warrants judicious use of corticosteroids and optimal glycaemic control. Our study highlights that good clinical outcome can be achieved in invasive mucormycosis provided prompt treatment is instituted with aggressive surgical debridement and antifungal medication.

Soft Palate Subacute Necrotising Sialadenitis: A Case Report.

Subacute Necrotising Sialadenitis (SANS) is a self-limiting, inflammatory disorder of minor salivary glands of unknown etiology. Minor salivary glands over soft and hard palate are most commonly affected. SANS shares considerable clinical features with necrotizing sialometaplasia, which is also the commonest differential diagnosis. We present an intriguing case of soft palate SANS in a 55 year old lady.

Dermoid Cyst of the Parotid Gland: A Rare Entity.

Dermoid cysts of the head and neck are a rare entity. These cysts are benign cystic malformations and histologically composed of tissues originating from ectoderm and mesoderm. Dermoid cysts usually presents as midline neck mass and rarely appear in lateral region. These are extremely rare in parotid gland, however should be considered as a differential in the list of parotid mass. There are a few cases published till date. Superficial parotidectomy is suggested as surgical treatment, however sometimes enucleation is also sufficient. There are only very few case reports published on dermoid cysts in parotid glands. We present a rare case of this entity and the challenges faced in making diagnosis with a short review of the literature.

Audit of Complications in an Otolaryngology Led Skull-Base Surgical Practice.

Objective This study was aimed to classify and study complications of surgery of the cranial base, primarily from an otorhinolaryngology perspective. Design This study was designed with consecutive cohort of skull base surgical cases. Setting Tertiary referral academic center. Participants Patients having skull-base surgery at a otorhinolaryngology based skull-base unit, from 2002 to 2015. Main Outcome Measures Enumeration of complications is the main outcome of this study. Surgical procedures, categorized for complexity as per a unified system, are applicable to endoscopic and open procedures. Complications were categorized as per the British Association of Otolaryngologists coding of surgical complications. Complication classified as major if life-threatening, causing permanent disability, or compromising the result of surgery. Results A total of 342 patients ( n = 342) were operated; 13 patients' records were excluded due to < 6 months posttreatment follow-up. The study group constituted 204 anterior skull-base (endoscopic, 120; open/external, 84) and 125 lateral skull-base procedures. Complication rates noted to increase in both groups with increasing complexity of surgical intervention. Anterior skull-base surgery (total complications, 11%; major, 3%; death, 0.5%) noted to have significantly less surgical complications than lateral skull-base surgery (total complications, 33%; major, 15%; death, 1.6%; p < 0.001). Among the anterior procedures no significant difference noted among endoscopic and external approaches when compared across similar surgical complexity. Conclusion Despite improvement in surgical and perioperative care, the overall major complication rate in a contemporary otolaryngology led, primarily extradural, skull-base practice is noted at 8%. Perioperative mortality, though rare, was encountered in 1%. A standard method for categorization of surgical complexity and the grade of complications as reported here is recommended.
