Dental and ENT Evaluation Before Liver Transplantation.

The assessment of dental and ear, nose and throat (ENT) conditions holds significant importance in the pre-transplantation evaluation for individuals undergoing liver transplantation. This evaluation aims to address concerns related to dental and ENT issues both before and after liver transplantation. These concerns include the risk of sepsis, the impact of post-transplantation immunosuppression, the detection of existing malignancies, including oral potentially malignant disorders (OPMDs), and identifying any contraindications to the transplantation procedure. However, it is worth noting that there exists a notable absence of clear guidelines and protocols in the existing literature regarding this practice. Moreover, recent studies have presented conflicting results, and concerns have arisen regarding the cost-effectiveness of these evaluations. It is crucial to perform these investigations judiciously to avoid unnecessary testing burdens and delays in placing patients on waiting lists, particularly when considering live donor liver transplantation (LDLT) evaluations. A comprehensive examination of the oral and ENT regions, in conjunction with relevant laboratory tests, can play a pivotal role in identifying and managing oral and ENT diseases before the liver transplantation procedure. Timely recognition and treatment of potential issues are essential for minimizing perioperative morbidity and mortality. There is an evident need for prospective trials and studies to further explore and establish guidelines in the critical area of dental and ENT evaluation in liver transplantation recipients. Such research efforts would contribute significantly to enhancing our understanding and management of oral and ENT conditions in the pre-transplantation setting, ultimately improving patient care and outcomes.

Cochlear Implantation in a Case of Relapsing Polychondritis With Profound Hearing Loss and Labyrinthine Ossification.

Relapsing polychondritis is an autoimmune disorder causing inflammation of cartilaginous structures, sensory epithelium, and cardiovascular system. Hearing loss is a rare and dreadful complication of this pathology. We report a case of relapsing polychondritis in a 38-year-old female who developed gradually progressive bilateral profound hearing loss. She did not have any improvement with medical management. Cochlear implantation was performed to rehabilitate her hearing. As the scala tympani was obliterated, a scala vestibuli insertion was performed. A complete insertion was possible with a compressed electrode, and she had good evoked compound action potential scores. Her categories of auditory performance scores were 6 at the end of one year. Patients with relapsing polychondritis can progress to profound hearing loss in rare cases and should be carefully followed up to identify early labyrinthine ossification. A scala vestibuli insertion can be performed with good outcomes in cases with ossification involving scala tympani. The surgeon should be ready for a middle-turn cochleostomy or a drill-out procedure in patients with advanced ossification.

Endoscopic Tympanoplasty as an Alternative to Microscopic Tympanoplasty: A Comparative Study on Surgical Outcomes and patient satisfaction.

Background: Chronic otitis media treatment has evolved, with microscopic surgeries as the gold standard and endoscopic surgeries as a newer addition. Materials and Methods: This retrospective study includes 209 patients who underwent type 1 tympanoplasty, utilizing both endoscopic and microscopic techniques, between January 2019 and December 2022 at a tertiary care institute in India. The study aims to compare hearing outcomes, graft uptake, hospital stay, postoperative pain, and cosmesis between the two groups. Results: Mean AB gap closure was 17.09 + 5.98 dB in the endoscopic group and 16.74 + 5.05 dB in the microscopic group (P = 0.687). The duration of surgery was 79.26 ± 17.37 min in the Endoscopic group and 91.92 ± 15.35 min in the Microscopic group. (P = < 0.00001). The Endoscopic group experienced less post-operative pain, shorter hospital stay (P = < 0.00001, P = 0.0008), and exhibited better cosmetic outcomes (P = 0.00001) compared to the microscopic group. Conclusion: Endoscopic tympanoplasty is a better alternative to microscopic tympanoplasty, delivering comparable hearing outcomes, shorter surgical duration, improved pain scores, and better cosmesis.

A 37-Year-Old Man With Dyspnea, Bilateral Lung Consolidation, and a Tracheal Mass.

CASE PRESENTATION: A 37-year-old man presented to the ED with symptoms of productive cough, self-reported fever, and shortness of breath for the past 15 days. He was placed on noninvasive mechanical ventilation for respiratory distress. IV piperacillin-tazobactam and inhaled bronchodilators were promptly administered, and he was subsequently transferred to the respiratory ICU for further care. He had no history of bowel and bladder disturbance, altered sensorium, swelling of feet, or abdominal distention. He never used tobacco and denied a history of TB. Medical history was notable for recurrent hospitalizations and administration of multiple courses of antibiotics in the past for similar complaints. He often used inhaled bronchodilators/corticosteroids when clinically stable to relieve symptoms.

Comparing accuracy of cochlear measurements on magnetic resonance imaging and computed tomography: A step towards radiation-free cochlear implantation.

Objective: Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) are commonly employed in pre-operative evaluation for cochlear implant surgery. However, with a decrease in the age of implantation, even minor radiation exposure can cause detrimental effects on children over their lifetime. The current study compares different cochlear measurements from CT and MRI scans and evaluates the feasibility of using only an MRI scan for radiological evaluation before cochlear implantation. Methods: A longitudinal observational study was conducted on 94 ears/47 children, employing CT and MRI scans. The CT and MRI scan measurements include, A value, B value, Cochlear duct length (CDL), two-turn cochlear length, alpha and beta angles to look for cochlear orientation. Cochlear nerve diameter was measured using MRI. The values were compared. Results: The mean difference between measurements from CT and MRI scans for A value, B value, CDL, and two-turn cochlear length values was 0.567 ± 0.413 mm, 0.406 ± 0.368 mm, 2.365 ± 1.675 mm, and 2.063 ± 1.477 mm respectively without any significant difference. The alpha and beta angle measures were comparable, with no statistically significant difference. Conclusion: The study suggests that MRI scans can be the only radiological investigation needed with no radiation risk and reduces the cost of cochlear implant program in the paediatric population. There is no significant difference between the measurements obtained from CT and MRI scans. However, observed discrepancies in cochlear measurements across different populations require regionally or race-specific standardized values to ensure accurate diagnosis and precision in cochlear implant surgery. This aspect must be addressed to ensure positive outcomes for patients.

Newborn Hearing Screening with Two-Step Protocol and Risk Factor Identification: Our Experience at a Tertiary Care Centre in Eastern India.

Objective: To estimate the prevalence of hearing loss and identify the high-risk factors among neonates with hearing loss. Methods: Retrospective study done on 1054 infants in a tertiary care centre in Eastern India from 2020 to 2021 and approved by the Institutional Ethics Committee. A two-step protocol is used for screening. In the well-nursed group, OAE and BOA were performed. In the case of REFER results for automated ABR following OAE evaluation in well-nursed babies, a detailed audiological evaluation was scheduled to be carried out using diagnostic ABR within one month of age. In the high-risk group, hearing screening includes OAE, BOA, and AABR evaluations. AABR evaluation was performed as a part of the screening protocol irrespective of the results of OAE screening as PASS or REFER. Results: In our study among 1053 neonates screened, 375 were in the risk category, and 679 were without risk factors. The overall prevalence of hearing loss in neonates was 22.78 per 1000 screened neonates and 56 per 1000 among high-risk neonates. In the high-risk group, we were able to identify 4 cases of Auditory spectrum neuropathy disorder with the use of AABR during 1st step of screening. In multivariate regression analysis, the risk factors for hearing loss identified were NICU stay (OR = 3.6, 95% CI = 1.1-12.03) and Craniofacial anomalies (OR = 55.37, 95% CI = 16.48- 186.01). Conclusion: Early neonatal screening helps in the detection, intervention, and rehabilitation of hearing loss. The use of AABR in risk infant screening enhanced the chance of detection of auditory spectrum neuropathy disorder (ASND) cases.

Outcome of cochlear implantation in a case of cochlear aplasia with cochlear nerve deficiency.

Cochlear nerve deficiency in cochlear aplasia is a contraindication for cochlear implantation (CI) anticipating poor auditory response. Few authors have reported auditory outcomes even without nerves following CI. This study outlines the audiological outcomes of a patient in early childhood with cochlear aplasia and cochlear nerve deficiency who underwent CI. Auditory and speech-language development were assessed using the Categories of Auditory Performance (CAP) scale, Speech Intelligibility Rating (SIR) scale and Ling-6 sound test; at the time of switch-on, after 6 and 12 months of auditory verbal therapy. Significant differences across CAP, SIR and Ling-6 sound detection scores were noted, with the highest mean scores at the 12th-month postimplantation, indicating substantial improvement in auditory and speech-language skills. In cochlear aplasia cases, residual cochlear elements and nerve fibres cannot be ruled out. Our report emphasises the need for research, as this has the potential to impact the existing guidelines for CI candidacy.

Use of Technology to Improve the Adherence to Surgical Safety Checklists in the Operating Room.

BACKGROUND: Although checklists can improve safety in the operating room (OR), compliance with their use is variable. Use of a forcing function, a principle of human factors engineering, has not been reported earlier as a method of increasing checklist use. The authors conducted this study to determine the feasibility and effects of introducing a forcing function on OR surgical safety checklist implementation and adherence. METHODS: The authors developed and introduced the use of an electronic version of the surgical safety checklist on an Android application, provided on a personal device available in the OR. This application was linked by Bluetooth to electrocautery equipment, which could not be started before the electronic checklist was completed on the screen of the personal device. In the same OR, retrospective data from use of the traditional (paper-based) checklist were compared with data from the new electronic checklist for frequency of use, and completeness (percentage of all checklist items completed) at three stages of the surgical process-sign-in, time-out, and sign-out. RESULTS: The frequency of use was 100.0% for the electronic checklist, compared with 97.9% for the traditional checklist. The frequency of completeness was 27.1% for the traditional vs. 100.0% for the electronic (p < 0.001).The manual checklist's sign-out component was completed only 37.0% of the time. CONCLUSION: Although checklist use in some form was already high with the traditional checklist, completion rate was low and significantly increased with the use of the electronic checklist with a forcing function.

Endoscopic Repair of CSF Rhinorrhea: Our Experience at a Tertiary Centre.

Spontaneous or post-traumatic CSF (cerebrospinal-fluid) rhinorrhea occurs when there is a skull-base defect. In our study, we tried endoscopic approach, exclusively as surgical modality. To study feasibility of trans-nasal endoscopic approach for repair of skull-base defects and success rates at each anatomical subsite, with complications. Patients, who underwent endoscopic repair of CSF rhinorrhea between 2016 and 2019 were recruited into study. Details of investigative work-up, aetiology, surgery done, site of leak, number of surgical procedures done, post-operative complications and their management, success rate for each anatomical sub-site, was retrieved retrospectively and analyzed. All patients were initially managed with conservative measures before taking up for surgery. Eighteen-patients (male-11, female-7, mean age-40.3 years) with CSF rhinorrhea {spontaneous-5(27.7%), traumatic-13(62.3%)} were found. Sites of leak were cribriform-plate (CP), fovea-ethmoidalis (FE) and posterior-table of frontal-sinus (FS) in 8(44.4%), 5(27.7%) and 5(27.7%) respectively. Twelve (66.6%) patients had no postoperative complications. No patients with defects in CP had post-operative complication. Two (11.1%) patients with FS defect had meningitis, one (5.5%) patient with FS defect developed pneumocephalus. One (5.5%) patient developed frontal sinusitis at end of 4-months. Two (11.1%) patients, each with defects in FE and FS needed a revision repair on postoperative day 0 and 90-till date, none of the patients have any delayed procedure related complications or recurrences. Endoscopic repair of CSF leaks is the norm of the current day due to its minimally invasive nature. However, endoscopic repair of leaks through the frontal sinus were challenging and was associated with a high rate of complications.

Blindness Following Endoscopic Excision of Acinic Cell Carcinoma of Sphenoid Sinus: A Case Report.

Acinic cell carcinoma (A.C.C.) is a low-grade malignancy involving salivary glands. A.C.C. accounts for only 1-4% of all sinonasal malignancies. We report the case of a 45-year-old female who presented with A.C.C. of paranasal sinus who developed loss of vision after Endoscopic sinus surgery (E.S.S.). Blindness, though rare, is a devastating complication of E.S.S. In this report, the rare occurrence of a papillary cystic variant of A.C.C. in the sphenoid sinus is reported. The causes that may lead to blindness during E.S.S. are analyzed in the absence of direct neural trauma.

Outcomes in Managing Vascular Tinnitus: Institutional Experience and Review of 6-Year Literature.

To evaluate the outcomes in patients of vascular tinnitus managed at our institute. The clinical data of all patients diagnosed with pulsatile tinnitus from January 2014 to April 2022 and managed at AIIMS, Bhubaneswar, was retrospectively reviewed. The diagnosis, treatment and outcomes were analyzed. A 6-year literature review was performed from March 2015 to April 2021. Our series discusses managing eleven cases of vascular tinnitus with varied aetiology and their outcomes. Out of the eleven cases, eight patients underwent surgical or radiological intervention, and seven had complete resolution of symptoms. Of the eleven patients, three had partial resolution. The 6-year literature review revealed sigmoid and transverse sinus as the most common causative anatomical sites for pulsatile tinnitus. Amongst those who received an intervention, 83.56% of the patients had complete resolution of symptoms. Vascular tinnitus can be cured if the exact vessel causing it is localized. Clinical suspicion is based on the character of tinnitus and patient history. A careful evaluation of the head and neck sites for any vascular anomaly that can cause pulsatile tinnitus must be done. Radiology demonstrates treatable causes of it. It delineates the aberrant anatomical variations that can lead to this disturbing aetiology. Treatable causes are best addressed, and pathology should be taken care of. A multidisciplinary team comprising ENT surgeons, audiologists and interventional radiologists must identify and treat the pathology.

Efficacy of Two-phase Treatment Regimen for Rhino-facial Entomophthoromycosis: Our Experience and Review of Literature.

This paper reviews our institutional experience in the management of rhino-facial entomophthoromycosis, a rare subcutaneous fungal infection. We adopt a fixed two-phase protocol comprising an initial 'intensive phase' (two-drug regimen) followed by an 'eradication phase' (monotherapy). We present five patients treated between May 2013 and May 2020 in our institution who were subjected to the mentioned protocol. All five patients received six months of supersaturated potassium iodide solution and itraconazole, followed by four months of monotherapy with only supersaturated potassium iodide solution. All patients responded well to the treatment and were disease-free on follow-up of a minimum two years post-treatment. We recommend this procedure for all typical cases of entomophthoromycosis and suggest avoiding surgical intervention which may disseminate the fungus and delay response to treatment.

Management of Symptomatic Grade I and II Laryngeal Cleft: Experience of a Tertiary Care Center and Review of Literature.

Laryngeal cleft is a rare pathology and needs a high index of suspicion for diagnosis. Various classifications are used but the Inglis classification which describes 4 grades of cleft is most widely accepted. Grade 3 and 4 clefts are very rare and are usually associated with other congenital abnormalities. Grade 1 and 2 clefts are more common and can be easily corrected with good outcomes. We are presenting our experience with 9 cases of low grade (Grade 1 and 2) laryngeal cleft which were managed successfully in our department. Out of the 9 cases 4 failed conservative management and required a trans-oral repair. All patients improved with management, except one who intermittently developed another episode of pneumonia 2 months' post-surgery. However satisfactory cleft obliteration was confirmed on endoscopy and the patient has been under close follow up ever since. Majority of low grade laryngeal clefts can be managed with dietary modifications and feeding rehabilitation. Those who do not respond usually require surgical repair with near complete resolution of symptoms.

Efficacy of endoscopic repair for CSF otorrhoea in children with recurrent meningitis due to incomplete partition type 1.

OBJECTIVE: To review the efficacy of endoscopic management with or without cochlear implantation in a pediatric population presenting with recurrent meningitis due to inner ear incomplete partition type 1 (IP-1). MATERIALS AND METHODS: A multicentric report of 6 patients with a history of recurrent meningitis due to IP-1 was done. Radiological evaluation was performed to confirm the diagnosis. Transcanal endoscopic repair of the defect was performed in 3 cases, 2 cases underwent endoscope-assisted repair followed by cochlear implantation in the contralateral ear later, and 1 patient underwent endoscopic repair along with simultaneous cochlear implantation. RESULTS: Radiology confirmed the diagnosis and identified the site of the leak. A leak was detected in all cases from the stapes footplate. Two patients with unilateral deformity had a CSF-filled cyst protruding through a defect in the stapes footplate, and the rest of the four had a high flow CSF leak from the footplate. Five patients who underwent repair have had no further episodes of meningitis. One patient who received simultaneous implantation and repair developed postoperative meningitis managed successfully with antibiotics. CONCLUSION: Hearing loss due to inner ear deformity can be easily missed as a cause for recurrent meningitis, especially if unilateral. A high index of suspicion, audiological screening and radiology are essential to clinch the diagnosis. In such cases, a pure endoscopic or endoscopic assisted transcanal approach to repair CSF otorrhoea is an effective alternative to more radical procedures like subtotal petrosectomy with obliteration. In patients with bilateral profound hearing loss, simultaneous cochlear implantation and repair of the defect can be performed successfully.

Prevalence of Skip Metastases to Cervical Lymph-Nodes in Oral cavity Cancer in Eastern India-an observational study.

To determine the prevalence of skip metastases in Oral-squamous-cell-carcinoma (OSCC). This prospective observational study was carried out on 100-cases of biopsy proven OSCC who underwent surgical treatment for the primary tumor along with neck dissection (ND). Data regarding depth of invasion (DOI) by primary tumor, perineural-invasion, lymphovascular-invasion, presence of metastatic-lymph-node (level, size, number and extranodal-extension) were collected from histopathology reports and were analyzed. Out of 100-cases, 73-were-male and 27-were-female. Mean age was 49.5 ± 12.3 years (range 24-4 years). Common subsites of tumor were buccal-mucosa, tongue and lower-alveolus in 40, 37 and 14% respectively. Pathological staging of tumor were stage-I, stage-II, stage-III, stage-IVa and stage-IVb in 22, 14, 25, 22 and 15% cases respectively. Preoperative neck staging was cN0 in 50 necks (47.2%) and cN+ in 56 necks (52.8%). In 100-patients 106-NDs (unilateral-94 and bilateral-6) were performed. Type of NDs were Supraomohyoid, extended-Supraomohyoid and modified radical neck-dissection in 23,07and76 cases respectively. Prevalence of cervical lymph node metastases was 36% (pN + necks). Among 36pN + patients; 25 (69.4%) cases, 20 (55.5%) cases, 9 (25%) cases, 4 (11.1%) cases, 2 (5.5%) cases had metastases to level-I, II, III, IV and V respectively. Skip-metastases was present in four-cases {level-IIb:one-case (2.78%), level-III: two-cases (5.5%) and level-V:one-case (2.78%)}. No-skip-metastasis to level-IV was noticed. All-four-cases of skip-metastases were from advance cases of squamous-cell-carcinoma of tongue with DOI > 5 mm. Skip-metastases to levels IIb, IV and V are uncommon in cases of OSCC. Most of the metastasis in our study was noted to levels I, II and III in a predictable fashion. Thus, extensive ND can be avoided in patients to prevent complications and morbidities associated with the same.

Identification and Characterization of Burkholderia pseudomallei from Localized Pyogenic Infections in Eastern India: A Clinico-Microbiological Study.

Melioidosis, caused by Burkholderia pseudomallei, is increasingly recognized in several regions of the globe. The present study was performed to identify and determine the frequency of B. pseudomallei infection in localized pyogenic lesions in eastern India and describe their clinico-microbiological profile. Pus samples were subjected to standard microbiological techniques for isolation and identification of various bacteria, including B. pseudomallei, which were confirmed by PCR. The clinical and demographic details of patients with melioidosis and antimicrobial susceptibility pattern of B. pseudomallei isolates were analyzed. Of 245 samples, 126 (51.4%) were culture positive, yielding 137 isolates. Staphylococcus aureus was the predominant pathogen accounting for 54 (39.4%) isolates, followed by B. pseudomallei accounting for 34 (24.8%) isolates. The mean age of the patients with melioidosis was 39.1 years, with males (24/34; 70.6%) being affected more than females (10/34; 29.4%). A majority of the patients were laborers (12/34; 35.3), followed by homemakers (8/34; 23.5%). Head and neck abscesses (35.3%) were the most common presentation followed by pyogenic lesions of the musculoskeletal system (32.3%) and deep organ abscesses (23.5%). Clinical resolution of infection was observed in 31 (91.2%) patients, relapse in two (5.9%) patients, and death in one (2.9%) patient, respectively. Susceptibility testing revealed all B. pseudomallei isolates to be completely susceptible to the following antimicrobials: ceftazidime, trimethoprim-sulfamethoxazole, imipenem, and doxycycline, with one (2.9%) resistant to amoxicillin-clavulanic acid. Burkholderia pseudomallei is an emerging etiological agent of localized pyogenic infections in eastern India, affecting a mainly adult male population. An increased vigilance along with appropriate diagnostic techniques helps in accurate diagnosis facilitating appropriate therapy.

Exclusive endoscopic transcanal approach to lateral skull base lesions: Institutional experience of 3 cases.

INTRODUCTION: Majority of petrous bone and lateral skull base pathologies are benign in nature. The complex anatomy usually warrants an extensive approach with associated morbidity. CASE SUMMARY: Two cases of petrous bone cholesteatoma (1 congenital cholesteatoma with facial palsy and 1 acquired cholesteatoma) and a case of glomus tympanicum were treated with exclusive endoscopic transcanal approach. The cases of petrous cholesteatoma were addressed with trans-promontorial and infra-cochlear approaches. The mean operative time was approximately 140 min. No CSF otorrhoea was noticed in the post-operative period. The average period of hospital stay was 3.7 days. CONCLUSION: In the subset of cases with limited benign disease an endoscopic trans-canal approach is a better alternative to an external approach. It decreases operative time, blood loss, chance of meningitis, morbidity and hospital stay. The lack of depth perception is a major hurdle which can be come over by experience in endoscopic middle ear surgery. This approach can create direct access to cochlea/petrous apex/internal auditory canal (IAC)/Supra-geniculate ganglion region.

Heerfordt's Syndrome Presenting with Recurrent Facial Nerve Palsy: Case report and 10-year literature review.

Heerfordt's syndrome is defined as a combination of facial palsy, parotid swelling, uveitis and fever in sarcoidosis cases. Heerfordt's syndrome as a cause of facial palsy is very rare. We report a case of alternating facial nerve palsy in a 52-year-old female initially treated for Bell's palsy. The patient was referred to the All India Institute of Medical Sciences, Bhubaneswar, India, in January 2013 for clinical evaluation. She was found to have a parotid swelling and anterior intermediate uveitis. A pathoradiological evaluation suggested sarcoidosis and a final diagnosis of Heerfordt's syndrome was made. Steroid treatment was initiated which led to an improvement in the facial palsy and uveitis as well as the disappearance of the parotid swelling with a corresponding decrease in angiotensin-converting enzyme levels. An English literature review was carried out to analyse the varied presentation of this syndrome. The analysis focused on presenting symptoms, biochemical markers and radiological findings of Heerfordt's syndrome cases.
