Hemithyroidectomy in Papillary Thyroid Cancers: A Prospective, Single Institutional Surgical Audit and Contemplating on the Clinical Implications of 2015 American Thyroid Association Guidelines.

Papillary thyroid carcinoma (PTC) contributes to 88% of thyroid malignancies and its extent of surgical management has been a topic of debate in the past 2 decades. American thyroid association (ATA) recommendations have been periodically updated for its robust and evidence-based management. We present our experience in implementing 2015 ATA guidelines, assessment of surgical outcomes of hemithyroidectomy in PTC ≤ 4 cm and contemplating on the potential clinical implications of 2015 ATA guidelines. A prospective study in a cohort of Bethesda class V and VI PTC with nodule ≤ 4 cm who underwent Hemithyroidectomy between 2012 and 2020. Data on thyroid nodule evaluation, management, histopathology and follow up were used for risk stratification. Of 37 patients, 27 (72.9%) were low risk and 10 (37%) were intermediate risk ATA group. 4 (40%) intermediate risk patients had structural incomplete response and underwent completion thyroidectomy. 1 (2.7%) out of 4 completion surgery patients required adjuvant radio-ablation iodine (RAI) and 3 patients were under surveillance. Overall, 2 (5.4%) of 37 patients, 1 each from low and intermediate groups were given remnant RAI in view of aggressive histology, old age and unwillingness for a completion surgery. During follow up of 4.94 ± 2.4 years, 35 (94.5%) showed excellent response and 2 (5.4%) showed biochemical incomplete response. The difference in RFS between two groups was statistically significant with p < 0.001. Thyroid preserving surgery combined with real time risk stratification seems appropriate for low and intermediate risk PTC ≤ 4 cm.

An Infected Third Branchial Pouch Cyst presenting with Acute Stridor in an Infant.

Branchial pouch cysts clinically mimic deep neck space infection and misdiagnosis leads to surgical drainage which can complicate into a persistently draining sinus or fistula. We present a unique case of infected third branchial pouch cyst in an infant who presented with acute stridor and our experience in its management.

Endoscope Assisted Combined Drainage of Sino-Orbital Abscess: Technique Revisited.

Orbital complications of acute rhinosinusitis may present with painful proptosis and ophthalmoplegia. Surgical management, when required comprises of endonasal endoscopic sinus clearance with or without external orbital abscess drainage. External drainage involves blind dissection and carries a risk of iatrogenic injury to periorbital structures. We describe a novel technique of endoscope guided orbital abscess drainage under direct visualisation via the external incision site. Patients with orbital cellulitis secondary to rhinosinusitis and planned for surgical intervention were recruited. After endonasal endoscopic sinus surgery, the orbital abscess cavity was opened and an endoscope was inserted externally. The cavity was examined; loculi were opened under direct visualisation till drainage was complete. This procedure was performed in seven patients with a successful outcome. The mean time to resolution was 1.5 months (36.4 ± 18.2 days). None of the patients had any recurrence or residual disease on follow up. In addition, in two cases with obstructed sinus drainage and "walling off" of frontal sinus, visualisation of the instrument placed in the drained abscess cavity via endo-nasally inserted endoscope confirmed the re-establishment of continuity of sinus opening. This approach may allow the surgeon to drain multiloculated abscess completely under direct visualization while minimising iatrogenic damage to periorbital structures. Real time display using endoscopic camera on the monitor screen also serves as a teaching and training tool during the procedure. Technique utilises the existing endoscopic set-up without the need for additional instrumentation.

Essential oil nebulization in mild COVID-19(EONCO): Early phase exploratory clinical trial.

Background: Medications studied for therapeutic benefits in coronavirus disease 2019 (COVID-19) have produced inconclusive efficacy results except for steroids. Objective: A prospective randomized open-label, parallel-arm Phase I/II clinical trial was planned to compare essential oil (EO) blend versus placebo nebulization in mild COVID-19. Methods: A Phase I safety evaluation was carried out in a single ascending and multiple ascending dose study designs. We assessed Phase II therapeutic efficacy on COVID-19 and general respiratory symptoms on days 0, 3, 5, 7, 10, and 14 on the predesigned case record form. Viremia was evaluated on day 0, day 5, and day 10. Results: Dose-limiting toxicities were not reached with the doses, frequencies, and duration studied, thus confirming the formulation's preliminary safety. General respiratory symptoms (p < 0.001), anosmia (p < 0.05), and dysgeusia (p < 0.001) benefited significantly with the use of EO blend nebulization compared to placebo. Symptomatic COVID-19 participants with mild disease did not show treatment benefits in terms of symptomatic relief (p = 1.0) and viremia clearance (p = 0.74) compared to the placebo. EO blend was found to be associated with the reduced evolution of symptoms in previously asymptomatic reverse transcription polymerase chain reaction (RT-PCR)-positive study participants (p = 0.034). Conclusion: EO nebulization appears to be a safer add-on symptomatic relief approach for mild COVID-19. However, the direct antiviral action of the EO blend needs to be assessed with different concentrations of combinations of individual phytochemicals in the EO blend.

Comparison of master two-step exercise stress test versus six-min walk test in patients tested positive for SARS-CoV-2.

Background and Aim: There has been a lack of uniformity on how to triage coronavirus disease 2019 (COVID-19) patients visiting the emergency units of hospitals. Triage tools are themselves spreading the pandemic in hospital areas. The present study compared a master two-step (M2ST) exercise stress test versus a 6-min walk test (6MWT) in COVID-19-positive patients visiting the emergency unit of a hospital. Materials and Methods: Thirty-nine patients underwent 6MWT followed by M2ST, while another set of 38 patients underwent M2ST followed by 6MWT in this randomized, crossover, open-label, and noninferiority study. The exercise tests assessed the change from baseline in SpO2, heart rate (HR), respiratory rate, blood pressure, exertion, and dyspnea on the modified-Borg scale. Results: Noninferiority was established for SpO2 (P < 0.05), systolic blood pressure (SBP; P < 0.001), and diastolic blood pressure (DBP; P < 0.05), but not for HR (P = 0.3) and respiratory rate (P = 0.6). The difference between the pretest and posttest (delta change) values for the parameters SpO2, respiratory rate, HR, SBP, and DBP correlated significantly (P < 0.001) with Pearson correlation coefficient (r = 0.764, 0.783, 0.473, 0.838, and 0.783, respectively). The delta change values of modified-Borg scale for dyspnea (P = 0.291) and exertion (P = 0.208) were statistically insignificant between the two exercise tests. However, the correlation between the tests was statistically significant (P < 0.001). Conclusion: M2ST, a timesaving, cost-effective, and easy to perform exercise stress test, has been identified as a reliable alternative for 6MWT.

Surgical Challenges in a Case of a Recurrent Giant Pleomorphic Liposarcoma of Neck And Mediastinum in a Child: A Rare Occurrence.

Liposarcomas are rare in childhood, representing < 1% of all childhood soft tissue sarcomas. The most frequent site of involvement are the extremities with the involvement of head and neck being an absolute rarity. Pleomorphic subtype of liposarcoma is pretty aggressive and hence portends a poor prognosis. Here, we present the case of a child who presented with a recurrence of liposarcoma in the neck and mediastinum within 3 months of the index surgery. Supplementary Information: The online version contains supplementary material available at 10.1007/s12070-021-02837-w.

Tele-Otolaryngology at a Tertiary Care Center in North India During COVID-19 Pandemic Lockdown: A Validated Patient Feedback Questionnaire Based Study.

Providing medical care using the telecommunication networks holds the promise of increased access and efficiency of healthcare particularly during global emergencies like the Coronavirus disease 2019 (COVID-19) pandemic. Most of the hospital setups worldwide have put telemedicine into practice ever since the onset of the COVID-19 pandemic. This study aimed at assessing the effectiveness of Tele-otolaryngology (TO) at a tertiary care centre during the pandemic lockdown. A validated patient feedback questionnaire was developed and distributed to 2577 patients who utilised the TO mobile health service at our institute. Patient feedback-based assessment of TO effectiveness during COVID-19 lockdown was carried out. The validated questionnaire in English and Hindi was statistically robust with Cronbach's alpha value of 0.808 and 0.886 respectively. 1751 patients completed their feedback to the questionnaire. 97.5% utilised WhatsApp for TO consultation. 15.2% patients were detected of Severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) infection with TO guidance. Up to 75% patients had a positive response to the questionnaire and 91.1% opined of savings achieved either with travel time, cost incurred or the treatment time. With respect to patient health status, 71.5% recovered, 20.1% had no change and 8.4% deteriorated with a mortality rate of 1.65%. Telehealth in otolaryngology during the COVID-19 pandemic lockdown was indispensable in managing exigencies. Redesigning of clinical protocol and technical constraints, clinician training and a validated patient feedback questionnaire would effectively bestow upon the global emergencies.

Early presentation of traumatic pseudoaneurysm of deep lingual artery as a massive oral bleed.

Tongue trauma with active bleed is most commonly due to the ruptured lingual artery and its branches, whereas delayed haemorrhage is usually secondary to pseudoaneurysm formation. This case is a unique presentation of traumatic tongue bleeds with early formation of pseudoaneurysm of a lingual artery branch. We present our experience in its management. A contrast-enhanced CT (CECT) with angiography detected right deep lingual artery pseudoaneurysm, which was managed by endovascular gelfoam embolisation followed by tongue laceration repair. Tongue bleed stopped immediately post embolisation; tongue viability and functions restored on postoperative day 1 of repair. No complications like secondary haemorrhage or tongue necrosis were noted at 1-month follow-up. High index of suspicion for lingual artery and/or its branch pseudoaneurysm is crucial in acute and uncontrollable traumatic tongue bleed. A CECT is a minimum norm in early diagnosis. Choice of management is the cornerstone of a successful outcome.

Plasma Ablation-Assisted Endoscopic Endonasal Transpterygoid Approach to Sphenoid Lateral Recess Cerebrospinal Fluid Leaks: Technique and Outcome.

BACKGROUND: Management of sphenoid lateral recess (SLR) cerebrospinal fluid (CSF) leaks present a challenge because of the location and requiring complete visualization of the defect for a successful repair. The endoscopic endonasal transpterygoid approach (EETPA) is considered the gold standard in addressing these defects. We lay out our experience in implementing this approach with plasma ablation. METHODS: This is a case series of 11 diagnosed patients of SLR CSF leaks who underwent plasma ablation-assisted EETPA repair by a single surgeon between 2011 and 2020 at our institution. Outcomes in terms of surgical field grade on the Wormald 11-point grading scale, postoperative complications, healing on nasal endoscopy and imaging, and surgical success rate were assessed. RESULTS: The etiology was spontaneous leak in 10 (90.9%) patients and secondary to temporal lobe abscess and/or meningitis in one (9.09%). Three (27%) patients were previously operated elsewhere by the transsphenoidal route, which we reoperated by this technique. As per Wormald grading, grade 1 field in 3 (27.27%), grade 2 in 6 (54.5%), and grade 3 in 2 cases (18.18%) were noted. Complications occurred in 3 patients (27%) in the form of dry eye (9%), meningitis (9%), and transient CSF rhinorrhea in the immediate postoperative period (9%). Repair sites were well healed on follow-up nasal endoscopy and imaging. The surgical success rate was 100%. CONCLUSIONS: Plasma ablation-assisted EETPA allows for a uninostril approach to the SLR, easy accessibility, and better visualization with a bloodless field, which allows appropriate repair, thus minimizing complications and preventing recurrence.

Hemorrhage in Onodi Cell Leading to Traumatic Optic Neuropathy.

Traumatic optic neuropathy (TON) is an important cause of vision loss in the setting of cranial and/or facial trauma. Both direct and indirect variants exist, with the latter being more common. We describe the case of a young male presenting with loss of vision following trauma with an intact globe, an intraorbital foreign body, and Onodi cell hemorrhage. The challenges in diagnoses of type of TON, exact pathology, and management are discussed. We also highlight the role of thin section digital computed tomography imaging which is paramount for timely detection of subtle injuries and their management.

Reversal of vision loss after traumatic optic neuropathy.

Traumatic optic neuropathy is sinister sequelae of craniofacial trauma leading to vision loss. The decision between early medical or surgical intervention is usually individualised. Visual evoked potentials may guide the treatment plan. We describe a young male presenting 5 days after a road traffic accident with no perception of light vision in the right eye. He was managed medically with high dose of intravenous steroids. At the 3-month follow-up, he reported a reversal of vision loss with return of visual acuity to 3/60, which improved to 6/36 at 5 months and remained stable at 8 months.

Can Sentinel Lymph Node Biopsy Predict Various Levels of Echelon Nodes in Oral Cancers?

Abstract Introduction The efficacy of sentinel node biopsy in early stage oral cancer is well established. Its evolving role can be reinforced by further studies. Objective Analyzing the predictability of the levels of echelon nodes for various oral cavity tumor subsites on sentinel node biopsy. Methods A prospective study of 20 patients with stage I/II oral squamous cell carcinoma who underwent sentinel node biopsy-guided neck dissection between January 2017 and 2018 at our institute. The procedure included radiotracer injection, imaging (lymphoscintigraphy, single photon emission computed tomography-computed tomography), and gamma probe application. Sentinel node detection on imaging and gamma probe were compared. Results Out of 20 patients, 13 (65%) had carcinoma of the tongue, 6 (30%) had buccal mucosa carcinoma, and 1 (5%) had retromolar trigone carcinoma. Themean age of the patients was 52.3 years. A total of 13 (65%) patients were male, and 7 (35%) were female. The sentinel node identification rates with imaging and gamma probe were of 70% and 100% respectively. In tongue and retromolar trigone primaries, the most common first-echelon nodes in both modalities were levels IIA and IB respectively. For buccal mucosa primaries, first-echelon nodes were detected only with the gamma probe, which was level IB. On imaging, second-echelon nodes were detected only for tongue primaries, and had equivalent incidence of levels II, III, and IV. On the gamma probe, level IIA, followed by III, and IV for the tongue, and level IIA were the most common second-echelon nodes for the buccal mucosa. Third-echelon nodes were detected only with the gamma probe for tongue carcinoma at level IV. Conclusion The combined use of imaging and gamma probe provides the best results, with high identification rate and predictability of echelon levels.

Variation of grain quality characters and marker-trait association in rice (Oryza sativa L.).

A set of 24 genotypes were studied for 17 grain quality characters and validated with the reported associated rice microsatellite markers with grain quality characters. Using 23 polymorphic markers distributed across 11 chromosomes marker-trait associations were studied. The percentage of polymorphism information content (PIC) of the markers ranged between 54.0 and 86.7. Eight markers with >80% and seven markers with >70% of PIC were found to be efficient in differentiating the studied grain quality characters. A total of 37 significant marker-trait associations (P ≤ 0.09) were found with R2 ranging from 4.70% to 43.80%. Eight markers a (RM246, RM11, RM241, RM16427, RM421, RM3, RM234 and RM257) showed association with more than one character suggesting their utility for the selection for grain quality characters which can be deployed in the rice crop improvement programmes.
