Occipital Artery-Based Fascio-Cutaneous Pedicle Flap in Reconstruction of Head and Neck Defects: A Saviour Under Challenging Times.

Head and Neck cancer management has undergone many changes in the past few decades. Primarily advancements in reconstructive surgery for complex head and neck defects after extensive ablative surgeries. Many factors need to be considered in deciding the type of reconstruction. Any reconstruction is not without complications. We wish to present the reconstructive challenges we faced in recent times to reconstruct composite head and neck defects, situation where a salvage flap has to be chosen in a failed regional flap. An occipital artery-based pedicled fascio cutaneous flap is one such rescuer flap. It is a retrospective study of case records from January 2018 to January 2021 at our institute. Reviewed the clinical data of Cases in which occipital artery-based flap was used to reconstruct the composite head and neck defects. In the era of microvascular flap reconstruction, utilization of regional flaps is still a choice of reconstruction in the resource constraint setting. A less explored occipital artery-based flap is a reliable regional flap can be used in select cases with a good success.

Cross-Sectional Analysis of Videonystagmography (VNG) Findings in Balance Disorders.

OBJECTIVE: To understand the videonystagmography (VNG) findings in various balance disorders in 67 patients who presented to the outpatient department of an otorhinolaryngology clinic. MATERIALS AND METHODS: This cross-sectional study was conducted in the outpatient department of the otorhinolaryngology clinic of a tertiary care center. A total of 67 patients between the age group of 18 and 70 years with balance disorders were included in the study. VNG findings in different balance disorders were observed and analyzed. RESULTS: A total of 67 patients were enrolled in the study. Findings like caloric inversion and optokinetic nystagmus do not always indicate a central balance disorder due to technical errors and other limitations during the test. However, abnormal saccades seem to be a more relevant finding in central disorders. Rare variants of benign paroxysmal positional vertigo (BPPV) like multiple canal BPPV were also diagnosed using VNG. CONCLUSION: VNG has come out as a very useful test in our study aiding in 75% of diagnoses. The overall benefits of VNG in balance disorders are immense and necessitate their inclusion in every vertigo clinic.

Financial toxicity and mental well-being of the oral cancer survivors residing in a developing country in the era of COVID 19 pandemic - A cross-sectional study.

OBJECTIVES: The primary outcome measures evaluated the financial toxicity and mental well-being of the oral cancer survivors. METHODS: A cross-sectional study of oral cancer survivors who were disease-free for more than 6 months after treatment and visited the hospital for a routine follow-up is included in the study. Mental well-being and financial toxicity were evaluated using the Depression, Anxiety, and Stress Scale - 21 (DASS 21) and Comprehensive Score for financial Toxicity (COST- Functional Assessment of Chronic Illness Therapy) questionnaires. A literature review was done to compare the results with financial toxicity and mental health in cancer patients from the pre-pandemic era. RESULTS: A total of 79 oral cancer survivors were included in the study, predominantly males (M: F = 10:1). The age ranged from 26 to 75 years (The median age is 49). The full-time employment dropped from 83.5% in the pre-treatment period to 21.5% post-treatment. Depression was observed in 58.2% and anxiety in 72.2%. Unemployed survivors were observed to have more depression (OR = 1.3, 95% confidence interval (CI) = 0.3-5.4, p = 0.6), anxiety (OR = 3.5, 95% CI = 0.3-21.2, p = 0.1) and stress (OR = 1.6, 95% CI = 0.3-6.6, p = 0.5) than rest of the cohort. On univariate analysis, unemployed survivors (M = 11.8 ± 3.8, p = 0.01) had significantly poorer financial toxicity scores. Survivors with depression (M = 16.4 ± 7.1, p = 0.06) and stress (M = 14.4 ± 6.8, p = 0.002) had poor financial toxicity scores. On multifactorial analysis of variance, current employment (p = 0.04) and treatment modality (p = 0.05) were significant factors impacting the financial toxicity. CONCLUSION: There is a trend towards increased incidence of depression, anxiety, and stress among oral cancer survivors compared to the literature from the pre-COVID era. There is significant financial toxicity among either unemployed or part-time workers. This calls for urgent public/government intervention to prevent the long-term impact of financial toxicity on survival and quality of life.

Robust expression of LINE-1 retrotransposon encoded proteins in oral squamous cell carcinoma.

BACKGROUND: Oral Squamous Cell Carcinoma (OSCC) results from a series of genetic alteration in squamous cells. This particular type of cancer considers one of the most aggressive malignancies to control because of its frequent local invasions to the regional lymph node. Although several biomarkers have been reported, the key marker used to predict the behavior of the disease is largely unknown. Here we report Long INterpersed Element-1 (LINE1 or L1) retrotransposon activity in post-operative oral cancer samples. L1 is the only active retrotransposon occupying around 17% of the human genome with an estimated 500,000 copies. An active L1 encodes two proteins (L1ORF1p and L1ORF2p); both of which are critical in the process of retrotransposition. Several studies report that the L1 retrotransposon is highly active in many cancers. L1 activity is generally determined by assaying L1ORF1p because of its high expression and availability of the antibody. However, due to its lower expression and unavailability of a robust antibody, detection of L1ORF2p has been limited. L1ORF2p is the crucial protein in the process of retrotransposition as it provides endonuclease and reverse transcriptase (RT) activity. METHODS: Immunohistochemistry and Western blotting were performed on the post-operative oral cancer samples and murine tissues. RESULTS: Using in house novel antibodies against both the L1 proteins (L1ORF1p and L1ORF2p), we found L1 retrotransposon is extremely active in post-operative oral cancer tissues. Here, we report a novel human L1ORF2p antibody generated using an 80-amino-acid stretch from the RT domain, which is highly conserved among different species. The antibody detects significant L1ORF2p expression in human oral squamous cell carcinoma (OSCC) samples and murine germ tissues. CONCLUSIONS: We report exceptionally high L1ORF1p and L1ORF2p expression in post-operative oral cancer samples. The novel L1ORF2p antibody reported in this study will serve as a useful tool to understand why L1 activity is deregulated in OSCC and how it contributes to the progression of this particular cancer. Cross-species reactivity of L1ORF2p antibody due to the conserved epitope will be useful to study the retrotransposon biology in mice and rat germ tissues.

Facial disfigurement due to olfactory neuroblastoma: beauty regained with chemotherapy.

BACKGROUND: Olfactory neuroblastoma (ONB) is a sinonasal malignancy seldom seen in clinical practice. It is also known by various other names like esthesioneuroblastoma, esthesioneuroepithelioma, esthesioneurocytoma, and esthesioneuroma. Surgery and radiation therapy are considered as standard treatment modalities for ONB; however, the role of chemotherapy is not well established. AIMS: We aim to define the role of chemotherapy in the neoadjuvant setting in a case of ONB. METHODS AND RESULTS: We report a young female patient presenting with a naso-facial swelling causing facial disfigurement, proptosis, decreased visual acuity, and poor performance status. She was diagnosed with advanced-stage ONB. Prompt administration of chemotherapy led to the improvement in the symptoms and rapid regression of the tumor mass. Later on, the tumor mass was excised completely without any neurological deficit. CONCLUSION: This report justifies the role of neoadjuvant chemotherapy in the management of ONB.

Unusual Sites for Extracranial Head-Neck Schwannomas.

Schwannomas are a frequent cause of swellings in the head and neck region. Due to the abundance of peripheral, cranial and autonomic nerves in this region, schwannomas can present in variety of locations, posing a diagnostic and therapeutic challenge to the surgeon. Unusual sites in head and neck region can have varied presentation depending on the site of origin. We identified unusual extracranial locations of head and neck schwannomas, their presenting features and surgical management. Retrospective review of cases of extracranial head and neck schwannomas operated in the Department of Otolaryngology and Head-Neck Surgery, All India Institute of Medical Sciences, New Delhi, a tertiary referral centre between July 2015 and June 2019. A total of 42 cases of extracranial head and neck schwannomas were operated. Among them, 9 cases were found to arise from uncommon sites, such as parotid gland (n = 1), infratemporal fossa (n = 2), external auditory canal (n = 1), subglottis (n = 1), false vocal cord (n = 1), frontal recess (n = 1), maxillary sinus (n = 1) and retromolar trigone (n = 1). All patients underwent excision via relevant approaches. Nerve of origin was identified in 4/9 cases. One case had postoperative neurological deficit. No recurrences were noted in mean follow-up of 19 months. Schwannomas ought to be considered as a differential diagnosis for swellings/ mass in any part of head and neck region. Comprehensive evaluation with appropriate imaging and histology should be done in all cases. Preoperative counselling and consent regarding neurological deficit pertaining to possible nerve of origin is required in each case.

Isolated Laryngeal Leishmaniasis: A Diagnostic Dilemma.

Isolated laryngeal Leishmaniasis is a rare entity in the Indian subcontinent. We describe a case of a 45 year old male with hoarseness and noisy breathing. Patient's initial histological and serological workup was inconclusive. Final biopsy findings (suggestive of Leishmania donovani), positive rK-39 serology and his native place being Bihar (endemic for Leishmaniasis) led us to the diagnosis. He was treated with high dose liposomal Amphotericin B to which he responded well. This case report highlights the importance of remaining aware of rare infectious causes of laryngitis. Timely diagnosis and intervention are crucial.

Navigation-assisted endonasal endoscopic optic nerve decompression in fibrous dysplasia.

A 12-year-old girl presented with left-sided decreased vision of 2-month duration. Clinical evaluation and imaging revealed fibrous dysplasia compressing the left optic nerve with no underlying endocrinological abnormalities. Best-corrected visual acuity showed progressive deterioration of vision over 2-month follow-up. She underwent navigation-assisted endonasal endoscopic optic nerve decompression. Post-surgery there was improvement in vision and it became normal (6/6). Six-month follow-up showed stable vision with no further complications.

Glomus Tumor of the Larynx: A Rare Synchronous Paraganglioma in a Patient with Bilateral Carotid Body Tumor Detected on 68Ga-DOTANOC PET/CT.

Paragangliomas are neoplasms arising from extra-adrenal chromaffin tissue. They frequently cause symptoms by overproduction of catecholamines with known predilection to multicentricity. We describe the case of a patient with bilateral carotid body tumor who underwent a baseline 68 Gallium labeled [1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid]-1-NaI3-Octreotide.
