Background: In oral carcinoma much effort has been made to predict the prognosis of patients but a sound understanding of underlying cell biology is likely to need progress. Recently, attention has been directed towards tumour associated tissue eosinophils and mast cells and their role in the biologic behavior of tumours. Aim: The retrospective study was used to evaluate the influence of tumour associated tissue eosinophils and mast cells on prognosis of oral squamous cell carcinoma (OSCC). Material and methods: The follow-up, of histopathologically diagnosed thirty cases of OSCC, was carried out for minimum period of 3 years. Special stains are wonderful they allow us to see which we can not see clear with routine H&E stain.Tissue sections were stained with special stains, Carbol Chromotrope for tissue eosinophil and Toluidine blue for tissue mast cell staining. Result: The results of the present study shows that increase infiltration of tissue eosinophils and mast cells in OSCC, associated with favourable prognosis. Conclusion: We concludes that infiltration of tissue eosinophils and mast cells are indicators of favourable prognosis in OSCC. Thus quantitative assessment of eosinophils and mast cells are the most important aspects of the microscopic evaluation of OSCC.

Background:The multifunctional involvement and infiltration of myeloid cells (tumor-associated tissue eosinophils [TATE] and mast cells) can provide a unique opportunity to define relevant effectors functions that may represent novel, therapeutic options for modulation of tumor onset/growth.Aim:Our study aimed to evaluate infiltration of myeloid cells (TATE and Mast cells) infiltration in different grades (WHO grading) of oral squamous cell carcinoma (OSCC).Materials and Methods:Total 30 cases of OSCC were selected for this study. Hematoxylin and eosin stain and toluidine blue special stain, to evaluate TATE and the mast cells infiltration, were used. Three-year follow-up of OSCC cases was done.Result:Among 30 cases, 63.33% cases of OSCC showed TATE-positive and 36.66% cases showed TATE-negative. Regarding mast cells infiltration, 66.66% OSCC cases showed mast cells positive and 33.33% cases did not show significant mast cells infiltration. We found significant association of TATE and mast cells infiltration in OSCC cases. These myeloid cells infiltration significantly associated with age of patients but did not show any significant association with gender, site, and habit of cases. When we compared these cells infiltration with clinical stages and different histological grades of tumor, we found their infiltration is decreasing, from Stages 1 to Stage 3 of tumor and from well to poorly differentiated carcinoma. We have also found the less infiltration of these myeloid in recurrence cases of OSCC.Conclusion:As the infiltration of TATE and mast cells are correlated, along with evaluation of TATE, we should also evaluate the presence of mast cells infiltration in OSCC. The assessment of myeloid cells could become, in the future, useful for therapeutic approaches in this subset of the patient.

Aim: Our study aimed to evaluate the infiltration of tissue eosinophils and mast cells in oral squamous cell carcinoma (OSCC) by using special stains. Study Design: Comparative study.

Background: Twins are similar in many ways owing to the genetical and environmental factors. However, still, there are certain things that are not similar among them, and this is the challenge for personal identification among the twins. Objectives: Our present study aimed to know and assess the similarities and differences present between the monozygotic (identical) and dizygotic (fraternal) twins in relation to lip prints, palm prints, fingerprints and blood group and to evaluate their heritability among parents and their offspring. Materials and Methods: The study group comprised 30 twins and their parents – 15 identical and 15 nonidentical twins. The age of twins ranged from 15 years to 40 years. Lip print, palm print, fingerprint and blood group were statistically analyzed. Results: All the data were subjected to statistical analysis. The identical twins showed more percentage of similarities in comparison to the non identical twins. The inheritance pattern was significant for twins in case of their lip prints while palm prints and finger prints showed no such significance in inheritance pattern whereas there was significant association seen in case of blood groups of identical twins and their parents. Conclusion: Lip prints, palm prints, fingerprints and blood groups are the important parameters in forensic science for individual identification. Many studies have been done till now in individual but very few studies done in twin population. To the best of knowledge, ours is the first study of its kind with multiple parameters and its heritability in twins. We have observed that heritability in twins with relation to lip print was statistically significant and all the parameters can be used independently to identify the twins.
