Areca nut and oral cancer.

INTRODUCTION: The association between areca nut consumption and oral cancer has been a subject of increasing concern in global public health. GLOBAL PERSPECTIVE: Areca nut, often chewed in various forms such as betel quid, is deeply rooted in cultural practices across Asia and other parts of the world. Epidemiological studies consistently reveal a significant correlation between areca nut use and the incidence of oral cancer, emphasizing the need for targeted preventive measures. The complex interplay of areca nut's bioactive compounds, particularly arecoline, with cellular processes, contributes to the initiation and progression of oral carcinogenesis. Mechanistic insights into the genotoxic and cytotoxic effects of its components underscore the urgency for comprehensive public health interventions. PUBLIC HEALTH: Efforts to address this public health challenge involve multidisciplinary approaches, encompassing education, policy implementation, and behavioral interventions. Understanding the socio-cultural factors influencing areca nut consumption is pivotal for designing effective awareness campaigns and cessation programs. CONCLUSION: As oral cancer remains a significant global health burden, unraveling the nuanced relationship between areca nut and its role in oral carcinogenesis is crucial for advancing preventive strategies and mitigating the impact of this modifiable risk factor.

Regression Derived Staging Model to Predict Overall and Disease Specific Survival in Patients With Major Salivary Gland Carcinomas With Independent External Validation.

PURPOSE: The current American Joint Cancer Committee (AJCC) staging system for salivary gland tumors does not include histology and grade in its classification despite their proven prognostic importance. We planned to analyze if a modified staging system integrating these two factors into the staging improves prognostic performance and then validate it externally. MATERIALS AND METHODS: From SEER database (2000-2018), patients with major salivary gland carcinoma who underwent surgical resection between 2004 and 2015 were analyzed. Histologies were recoded into two groups based on grade and type of histology into "Low Aggression" and "High aggression" groups. Cox proportional hazards model was used to identify predictor variables for overall survival and disease-specific survival and models were generated based on least absolute shrinkage and selection operator regression. Model performance was evaluated by Akaike Information Criterion, concordance index and calibration plot. The best model chosen was externally validated from our hospital database of patients who underwent surgery for salivary gland tumor between January 1, 2012 to December 31, 2019. RESULTS: Six thousand two hundred forty-six patients were analyzed with a median follow up of 58 months. Age > 65 years, male sex, metastatic disease, Histological Stratification, Grade of tumor, AJCC stage and Primary Site were the significant factors influencing overall survival and disease-specific survival. By least absolute shrinkage and selection operator regression method, Correlation analysis and Interaction testing by multiple regression, AJCC stage and Histological Risk stratification were used for generating four models, out of which the best model was selected by Akaike Information Criterion, C index and calibration plot. This model was then externally validated in our hospital database of 269 patients. CONCLUSION: We propose an externally validated modified salivary gland staging system that incorporates histology and grade of tumor for improved hazard discrimination among patient subgroups.

Cross-Sectional and Longitudinal Mental Health Status Prevailing among COVID-19 Patients in Mumbai, India.

Introduction: The aim was to determine the prevalence and predictors of depression among less symptomatic COVID-19 patients. Methods: A questionnaire-based assessment was conducted among asymptomatic or mildly symptomatic COVID-19 patients when admitted in a COVID-19 facility (T1) and after 6 months (T2). Interviews were conducted using the Patient Health Questionnaire-9 instrument. Socio-demographic details and length of facility stay were recorded. Changes in scores between the two-time points T1 and T2 were compared. Factors predicting depression were determined using Chi-square and Mann-Whitney U test during facility stay, and those predicting worsening over time were obtained using multivariate regression models. Results: Among the 91.4% (n = 450) participants, prevalence of depression was 38.4% (95% confidence interval [CI] = 34.0-43.0) with a significant increase of 7.8-fold (95% CI = 4.8-12.8) in depression as the duration of stay increased beyond a median of 5 days. A significant association was observed between higher income and lower depression (odds ratios = 0.6, P = 0.03). 84% (n = 378) responded at the second timepoint assessment after a median of 6.62 months (T2). There was a significant difference observed between the 2.6% (n = 6) that worsened into depression at T2 and the 73.8% (n = 107) that improved out of depression at T2 (P ≤ 0.001). Age >45 years (P = 0.007), males (P = 0.011) and reinfection (P = 0.039) significantly led to worsening of depression. Conclusion: There is a need for actively detecting and managing depression in institutionally quarantined survivors, considering limiting such quarantine to no more than a week, and providing routine screening and care for depression beyond this period.

A contemporary narrative review to guide molecular epidemiology of oral submucous fibrosis.

Oral submucous Fibrosis (OSMF) is a chronic disease that mainly affects the upper part of the aerodigestive tract. Areca nut and betel quid chewing has been established as the most significant causative factor for this condition. While OSMF is a predominantly Asian disease, the migrant populations from the region have taken the disease across the globe. Additionally, areca nut is now easily accessible in flavors and aggressively marketed. Many research activities have been undertaken for decades to understand the etiopathogenesis and risk factors of OSMF. Although OSMF is a slowly progressing disease, it has the potential to transform to an oral malignancy. This article is an attempt to review the literature and provide an update on its prevalence, etiopthogenesis and its diagnosis. We also highlight certain clinical, histopathological and molecular features that aid in the diagnosis and prognostication of OSMF, highlighting the importance of identifying the possibly high risk OSMF that is prone to malignant transformation. Using this information, future directions can be developed to include treatmentof OSMF through a dynamic gene-specific approach.

A prospective study to determine the cost of illness for oral cancer in India.

India accounts for almost a third of the global burden of oral cancer, a situation worsened by the inability to afford care. When available, aid is often insufficient, and costing is based on informal estimations. This study objectively determines direct healthcare costs of oral cancer in India. The study was performed from a healthcare provider's perspective using a validated bottom-up method. Care pathways were determined by prospectively observing the natural management of 100 oral cancer patients treated between October 2019 and March 2020. Specific costing categories were built across services, and apportioned values for each interaction was averaged. Costs of treatment and service utilisation were obtained using probabilistic sensitivity analyses. The unit cost of treating advanced stages (United States Dollar (USD) 2,717) was found to be 42% greater than early stages (USD1,568). There was an 11% reduction in unit costs with increases in socioeconomic status. Medical equipment accounted for 97.8% of capital costs, with the highest contributor being imaging services. Variable costs for surgery in advanced stages were 1.4 times higher than early stages. Compared to surgery alone, the average cost of treatment increased by 44.6% with adjuvant therapy. These results show that over the next decade, India will incur an economic burden of USD 3 billion towards the direct healthcare of oral cancer. Early detection and prevention strategies leading to 20% reduction in advanced stage disease could save USD 30 million annually. These results are critical to deliver a disease-driven and objective reform for oral cancer care.

Clinical trials during COVID-19.

As this ever-evolving pandemic lays itself, more of its impact is being understood. Until recently, most guidelines were reported to aid in managing and treating suspected or confirmed cases. Research institutions around the world are responding with a sense of confusion. Some are continuing routinely, especially those who are overseeing clinical trials that could offer life-saving therapies, particularly against the novel coronavirus. Since research must continue even in the face of a shutdown, we aim to collate the currently available recommendations from various organizations and provide guidance to head and neck researchers across the world during these trying times.

Tobacco use and vaping in the COVID-19 era.

Health crises have become a popular topic of discussion. In the wave of the ongoing pandemic, experts have suggested the role of vaping and other tobacco product use exemplifying the vulnerability of the population to contract the COVID-19. We discuss some of the events that led up to these conclusions and also offer a unique insight into another form of tobacco use that is potentially propagating its spread especially in the South Asian region-chewed tobacco. Both of these have been a perennial issue that head and neck cancer surgeons have been dealing with. Governments and head and neck cancer care providers now have an opportunity to deal with a common enemy in the midst of this pandemic.

Navigating the impact of COVID-19 on palliative care for head and neck cancer.

Health care services are being confronted by a daily dilemma of who can receive critical care and who cannot. In a palliative care clinic, this apprehension gets exemplified, as these patients have limited life expectancy. The head and neck region further makes things critical, as it comprises of all the sites through which the SARS-CoV-2 can be transmitted. This document strives to define the ways in which the head and neck cancer services can contribute to better patient care in a triage context. Practical steps suggested are protective equipment use, ensuring access to critical drugs (such as opioids), greater use of telemedicine consultations, discussing advance care plans, and embracing the role of a wider community support.

Refractory Sjogrens syndrome: Is parotidectomy justified?

Primary and secondary Sjogrens syndrome (SS) is the classification used, according to the American-European Consensus Group Criteria. Salivary and lacrimal gland dysfunctions are the usual hallmark of the disease, but the involvement of other exocrine glands and extraglandular manifestations of the disease do occur. In rare cases, few patients are refractory to the conventional therapy and due to the sudden increase in size of a mass and the esthetic and psychological concerns of a "cancerous growth," the surgical treatment modalities have to be modified. There is a significant lack of contemporary literature on the indications for surgery in refractory SS, and the option should be given in patients with esthetic concerns, risk of malignancy, and to improve the overall quality of life.

Lymphocytoma cutis: diagnostic enigma for the maxillofacial surgeon.

Cutaneous lymphoid hyperplasia (CLH) is a cutaneous pseudolymphoma with a worldwide distribution, equally affecting all races and ethnic groups. Due to its vast array of characteristics, it is most often missed in the differential diagnosis of firm to soft lumps on the head and neck. A systematic approach to the workup and diagnosis along with treatment of such lesions is discussed in this article. A 20-year-old Asian Indian female presented to our Oral and Maxillofacial unit with a lump on the left side of her forehead for 1 month. Local examination revealed a 2.5×3.0 cm2, well circumscribed swelling over the left para median region that was firm to doughy and non-tender. There was no other significant finding on general examination. Excisional biopsy of the lesion was performed, followed by histopathologic processing. The general etiology, pathogenesis, clinical presentation, differential diagnosis, clinical course, prognosis, treatment, and prevention have been discussed in line with the recent modalities of diagnosis and treatment of CLH. Due to the overlapping clinical and histological characteristics of CLH with many other lesions, it is important to consider this lesion in the differential diagnosis of cutaneous lesions.
