Insights on betel-quid and coca chewing

Oral squamous cell carcinoma in coca chewers from a north region of Argentina: A case series and review of literature

Chewing coca leaves is a habit still practiced in Bolivia, Peru and Argentina. There is scarce evidence in the relationship between this habit and development of oral squamous cell carcinoma (OSCC), some authors have found oral epithelial changes in coca chewers. This study aimed to present a case series of patients with a coca chewing habit that developed OSCC, in the absence of risk factors for oral cancer. Patients were evaluated in Hospital Señor del Milagro, Salta, Argentina. None of them had a relevant morbid history and presented intraoral tumors, with an ulcerated surface on the gingivobuccal complex. Coca chewing habit was recorded in all cases. Present cases could start discussions and new lines of researches focusing on the habit of coca leaves chewing as a risk factor for OSCC. It would be very useful to know the underlying mechanisms between this habit and a possible role in oral carcinogenesis.

Invasive oral squamous cell carcinoma induced by concurrent smokeless tobacco and creamy snuff use: A case report

Oral squamous cell carcinomas (OSCC) are caused by chronic tobacco abuse. In this regard, the carcinogenic potential of smoking and smokeless forms of tobacco, including chewing tobacco and moist/dry snuff, has been widely documented. However, the effects of tobacco-containing products such as creamy snuff on oral health have not been widely reported. Here, we report on the clinical presentation of a patient with OSCC induced by concurrent chewing tobacco and creamy snuff use. The development and progression of mucosal carcinogenesis in the context of mixed tobacco use habits is discussed. With the increased availability of newer tobacco-containing products, it is important for clinicians to be aware of these products in the marketplace, including dentifrices and nicotine pouches, and counsel their patients regarding their health risks.

Impact of COVID-19 Lockdown on Oral Oncology-related Outpatient Volume at Indian Dental Institutions

AIM AND OBJECTIVE

This study aimed to evaluate the impact of the lockdown on oral oncology-related out-patient volume at Indian dental institutions.

MATERIALS AND METHODS

The total number of newly diagnosed cases of oral submucous fibrosis, oral leukoplakia, oral lichen planus, and oral cancers, recorded at two dental institutional settings before lockdown (January-March 2020) and after lockdown (June-August 2020), were included retrospectively and compared.

RESULTS

The study included a total of 797 cases at both institutions. At Institution-I, a total of 312 cases were recorded before the lockdown, and 63 cases were recorded after the lockdown. At Institution-II, a total of 311 cases were reported before lockdown, and 111 cases were recorded after lockdown. Comparisons between the pre-lockdown and post-lockdown data yielded a significant change in the proportions of oral sub-mucous fibrosis, oral leukoplakia, oral lichen planus, and oral cancers at both institutions (Chi-square test; p < 0.001). Following the lockdown, a substantial reduction was observed in the proportion of oral submucous fibrosis (OSMF) cases at both institutions, and the proportion of oral cancers increased at both institutions. There was a significant difference between the proportions of cases reported before lockdown at both institutions (p < 0.001). However, after-lockdown, no such differences were noted (p = 0.69); the absence of significance could most likely be due to the low sample size or low-power during the post-lockdown period.

CONCLUSION

The oral potentially malignant disorders (OPMD) and oral cancer (OC) patient volumes reduced substantially following lockdown. During the post-lockdown period, the proportion of oral cancers increased, whereas the proportion of OSMF cases decreased. Results indicate that OPMD and oral cancer patients were impacted differently by the lockdown.

CLINICAL SIGNIFICANCE

This study provides insight into the impact of lockdown and highlights the importance of reestablishing oral oncology-related patient care. A vital discussion is also provided on useful compensatory strategies that may reduce delays during the ongoing crisis. How to cite this article: Panta P, Reddy P, Misra SR, et al.
