Comparison of the Efficacy of Sediment Cytology over Oral Brush Cytology in Oral Leukoplakia.

Acta Cytol 2020 8;64(4):368-374. Epub 2019 Oct 8.

Department of Oral Pathology, Maratha Mandal's NGH Institute of Dental Sciences and Research Center, Belgaum, India.

Introduction: A method called sediment cytology includes the investigation of smears arranged from the sediment of the biopsy specimen fixatives. The sediment from this fixative is used to prepare smears and provides a potentially rich source for cytological material. Investigation of the fixative sediment and understanding of the cytological picture with pertinent clinical and radiological information permits diagnosis in a few hours.

Aim: To evaluate the diagnostic efficacy of sediment cytology and oral brush cytology compared with histopathological findings in oral leukoplakia (OL) cases.

Methods: Cytological smears were obtained from 30 clinically diagnosed OL lesions using 2 techniques: oral cytobrush and 10% formalin fixative sedimentation. Both smears were stained with Papanicolaou. Cytological smear evaluation was conducted with respect to cellularity, cell distribution, cellular clumping, and the presence of blood, debris, inflammatory cells, and microbial colonies. The cytopathological scores for all cases were compared between sediment and brush cytology and correlated with the histopathological diagnosis. For statistical analysis, the κ test and the Wilcoxon matched-pair test were used.

Results: The cytobrush technique had a sensitivity of 83.3% for OL cases histopathologically diagnosed as severe dysplasia, while the sediment cytology technique had a sensitivity of 16.6%. For moderate/mild dysplasia cases, the cytobrush technique had a sensitivity of 7.7%, whereas the sediment technique showed no diagnostic sensitivity.

Conclusion: Based on the results from the present study, sediment cytology, unlike oral brush cytology, is not a useful screening tool for the preliminary diagnosis of potentially malignant oral lesions.

Detection of antibodies against Aggregatibacter actinomycetemcomitans in serum and saliva through ELISA in periodontally healthy individuals and individuals with chronic periodontitis.

Microb Pathog 2018 Dec 9;125:438-442. Epub 2018 Oct 9.

Department of Molecular Biology & Immunology, Maratha Mandal's NGH Institute of Dental Sciences and Research Centre, Belgaum, 590010, Karnataka, India.

Background: Periodontitis is a persistent polymicrobial infection, which leads to chronic inflammation in the tooth supporting tissues. Aggregatibacter actinomycetemcomitans are normal commensals of oral cavity but are low in number in periodontally healthy subjects. They are one of the major pathogens aetiologically linked to periodontal disease. Plasma and salivary antibody measurement may be useful to support diagnosis, disease activity, classification and prognosis of periodontitis. The aim of the present study was to investigate the association between the serum and salivary antibody levels to A. actinomycetemcomitans and therefore, to find whether this association was varying in different grades of periodontitis.

Method: Total of 50 periodontally healthy and 50 chronic periodontitis subjects (35-65 years) of both sexes were included for the study. 2 ml of un-stimulated saliva and 5 ml of venous blood was collected under sterile conditions. The detection of antibodies against A. actinomycetemcomitans in periodontally healthy individuals and individuals with chronic periodontitis was performed using indirect ELISA.

Results: Results showed serum IgG, IgA mean levels against A. actinomycetemcomitans were higher in chronic periodontitis subjects compared to mean levels in periodontally healthy subjects. Similarly, salivary IgG, IgA levels were also raised in chronic periodontitis patients as compared in healthy subjects. Also the mean levels of serum IgG and salivary IgA were increased as the severity of disease increased.

Conclusion: Antibody titer using saliva and serum could be useful tool for screening of patients with chronic periodontitis. Further, monitoring the various phases of treatment outcome using saliva could be a useful, non-invasive, prognostic indicator.

Histomorphometric study to compare histological changes between oral squamous cell carcinoma and apparently normal adjacent oral mucosa.

Indian J Otolaryngol Head Neck Surg 2015 Mar 18;67(Suppl 1):21-8. Epub 2014 May 18.

Department of Oral Pathology and Microbiology, Maratha Mandal's NGH Institute of Dental Sciences, Belgaum, 590010 Karnataka India.

Despite the advances in surgery, radiotherapy and chemotherapy the annual death for oral squamous cell carcinoma (OSCC) is rising rapidly. The carcinoma has propensity to develop in a field of cancerization. Clinically may it be apparently normal mucosa (ANM) adjacent to squamous cell carcinoma which harbours certain discrete molecular alteration which ultimately reflects in cellular morphology. Hence the aim of the study is to assess histomorphometric changes in ANM adjacent to OSCC. A prospective study was done on 30 each of histologically diagnosed cases OSCC, ANM at least 1 cm away from OSCC, and normal oral mucosa (NOM). Cellular and nuclear morphometric measurements were assessed on hematoxylin and eosin sections using image analysis software. Statistical analysis was done using analysis of variance test and Tukey's post hoc test. The present study showed significant changes in cellular and nuclear area in superficial and invasive island of OSCC compared to ANM. The basal cells of ANM showed significant decrease in cellular and nuclear areas and nuclear cytoplasmic ratio when compared to NOM. Histomorphometry definitely can differentiate OSCC form ANM and NOM. The basal cells of ANM showed significant alterations in cellular area, nuclear area and nuclear cytoplasmic area when compared to NOM suggesting change in the field and have high risk of malignant transformation. These parameters can be used as indicator of field cancerization.

Analysis of Expression and Localization of TLR-2 by Immunofluorescent Technique in Healthy and Inflammed Oral Tissues.

J Clin Diagn Res 2013 Dec 15;7(12):2780-683. Epub 2013 Dec 15.

Introduction: Toll-like receptors (TLRs) are an important component of immune system. Among them, TLR-2 plays a dominant role in the oral tissues in initiating inflammation in chronic periodontitis. Not many studies have been done on quantitative expression of TLR-2 by using immunofluorescent techniques (IFT) in oral tissues. In this study, the expression and localisation of TLR-2 were detected in gingival tissues of chronic periodontitis patients and healthy individuals.

Material And Methods: Immuno Fluorescent Technique (IFT) was used for the expression and localization of TLR-2 in gingival tissue samples from 25 chronic periodontitis patients and from 25 healthy controls. Haematoxylin and Eosin staining was also done for all the samples to determine the histological characteristics of the gingival tissue samples.

Result: Both healthy and periodontitis gingival tissues expressed TLR-2. We found that the expression level of TLR-2 was higher in all the periodontitis patients than in healthy individuals. We also found out that the expression of TLR-2 was higher in the epithelial cells than in the connective tissue cells.

Conclusion: These data suggest a definite involvement of TLR-2 in initiating an inflammatory response in periodontal tissues. More studies are required to define the mechanisms and expression levels of TLR-2 in oral health and diseases.
