Introduction: Coronavirus disease 2019 (COVID-19) infection is associated with a variety of immune dysregulations. Aberrant immune function can lead to a plethora of lymphoproliferative and autoimmune dysfunctions. This study aimed to compare the reported results of fine-needle aspiration cytology (FNAC) for head and neck lesions in the pre- and post-COVID-19 period and to detect any change in the incidence of lymphoproliferative or granulomatous disorders. Material and Methods: A retrospective analytical study was conducted in a tertiary care hospital. FNAC records of duration from January 2017 to May 2023 were retrieved, collected, and analyzed. All patients who underwent FNAC for head and neck lesions were included, and incomplete, duplicate records and primary thyroid lesions were excluded from the study. Results: A total of 268 and 191 patients were included in the pre-COVID-19 and post-COVID-19 groups, respectively. Both groups were demographically comparable, without any statistically significant difference. The results showed that there is a statistically significant increase in cases diagnosed as lymphoproliferative disorders in the post-COVID-19 group as compared to the pre-COVID-19 group (12.04% vs 4.85%, P = 0.005), while the diagnosis of benign salivary gland tumors was significantly reduced (2.09% vs 5.97%, P = 0.045). There was no statistically significant difference between the study groups for other benign and neoplastic diagnoses. Conclusion: This study reveals a rise in lymphoproliferative disorders in the post-COVID-19 period. Although a causal association could not be established, the study indicates a temporal association. Hence, further research is warranted to explore the possible role of COVID-19 as an etiological agent for lymphoproliferative disorders.

Background: Development of obscured fingerprints on a diverse range of surfaces is a crucial aspect of forensic investigations. Aims and Objectives: In this particular study, the utilization of Syzygium cumini (L.) Skeels (Jamun) seed powder was examined for the purpose of revealing hidden fingerprints on a variety of surfaces, including both permeable and impermeable substrates. Materials and Methods: The seed powder was extracted using a simple process and was analysed using multiple analytical techniques. The efficacy of the jamun seed powder in developing latent fingerprints was evaluated. Results: The findings of this investigation demonstrate that the jamun seed powder was capable of producing fingerprint patterns of exceptional quality and clarity on numerous surfaces. Conclusion: This research highlights the potential use of jamun seed powder as a practical and effective alternative for the development of hidden fingerprints in forensic investigations, while also providing cost-effectiveness.
