Background: Oral exfoliative cytology is simple, non-invasive, inexpensive tools prone to subjective bias. Objective computer-based quantitative cytomorphometry technique was developed in last few decades to overcome its limitation. However, there is no consensus about the utility of cytomorphometry as a routine screening tool for early detection of dysplastic changes. Objectives: To review the utility of cytomorphometry in OPMDs in the detection of dysplasia changes. Method: A scoping review was undertaken focusing on cytomorphometric analysis in exfoliative cells for detection of oral epithelial dysplasia and cytomorphometric parameter denoting dysplasia. The systematic search was carried out in the online journal databases (Scopus, Google Scholar, PubMed, Web of Science) using keywords until December 2019 for the studies evaluated the cytomorphometry in the detection of dysplastic changes in OPMDs. Three authors independently extracted data using collection forms. Result: The search strategy found seven analytical cross-sectional studies for scoping review after eliminating 8940 out of 8947 initial results. The scoping review showed that cytomorphometry is useful tool in detecting the dysplastic changes in OPMDs. In addition, decrease in mean cellular area, increase in mean nuclear area, and decrease in mean cell diameter, increase mean nuclear diameter, increase in mean nuclear and cytoplasmic area ratio, associated with development of dysplastic changes in OPMDs. Conclusion: Cytomorphometry is promising tool, yet there is currently no-good evidence to support role of cytomorphometry in detecting the dysplastic changes in OPMDs in this setting. More research is required for refinement of cytomorphometry as a screening tool.
BACKGROUND:The clinicopathological distinctness of oral squamous cell carcinoma arising in the background of oral submucous fibrosis (OSCC-OSF) is well known; however, the molecular distinctness of this unique OSCC-OSF has not been investigated to date. With this in mind, we compared the expression of Ki67, CD105, and α-SMA between OSCC-OSF and oral squamous cell carcinoma (OSCC).METHODS:Formalin-fixed paraffin-embedded tissues of 105 OSCC-OSF and 112 OSCC cases were subjected to immunohistochemistry for evaluation of Ki67, CD105, and α-SMA expression.RESULTS:Ki67 (labeling index) LI, MVD and α-SMA expression were significantly higher in OSCC compared to OSCC-OSF. Ki67 LI and MVD was significantly higher in OSCC compared to OSCC-OSF in parameters such as well-differentiated, early TNM stage, non-metastatic, and more than 3-year survival. α-SMA expression was significantly higher in OSCC compared to OSCC-OSF in parameters such as moderate differentiation, metastatic lesions, and survival less than 3 years. Ki67 LI, MVD and α-SMA showed significant positive correlation with each other in OSCC and OSCC-OSF.CONCLUSION:Proliferation, neoangiogenesis and myofibroblast differentiation were significantly higher in the OSCC group compared to the OSCC-OSF group. This suggests the biological distinctness of OSCC-OSF, which could help the future development of targeted therapies.
Unicystic ameloblastoma (UA) shows clinical and radiologic characteristics of an odontogenic cyst, but histologically shows a typical ameloblastomatous epithelial lining part of the cyst cavity, with or without luminal and/or mural tumor proliferation. Very few cases were reported with variation in histological pattern but rarely with adenoid differentiation. Keeping this in mind, we here report a case report of plexiform UA with adenoid differentiation in maxilla.
Background: The first consultation with a health-care professional is crucial to make the correct diagnosis particularly with respect to narrating the symptoms encountered by the patient. Yet, currently, no information is available concerning the primary symptoms documented by patients with oral submucous fibrosis (OSF). Materials and Methods: A total of 158 OSF patients visiting outdoor patient departments (OSF-OPDs) and 104 pan shop customers (PSCs) were investigated. OSF-OPD cases and relevant PSCs cases were investigated to discover the chief complaints (CCs) leading to dental visits. Detailed demographic data, patient histories concerning relevant habits (with duration), and socioeconomic status were recorded. OSF cases were graded based on the degree of mouth opening. Results: Out of 158 OSF-OPD patients, only 43 (26.58%) reported relevant disease symptoms of OSF: in stage III, 28.57%, or stage IV, 38.09%. One hundred and sixteen patients (73.41%) reported CCs unrelated to OSF, and all of these cases were diagnosed with an early stage of OSF (stage I: 47.05% and stage II: 22.5%). Out of the total 104 PSCs, 66 PSCs have had prior dental consultations, but only five (4.80%) individuals had visited a health-care professional due to OSF-related CCs. Conclusion: A significant number of CCs made by OSF patients were unrelated to their disease signs and symptoms. There is a lack of awareness of OSF symptoms by pan chewers, thus hindering early detection.
AIM:The aim of this study was to investigate the expression of Ki67, CD105 and α-smooth muscle actin (α-SMA) expression in oral submucous fibrosis (OSF) and oral squamous cell carcinoma in the background of OSF (OSCC-SMF).METHODS:The study was carried out on paraffin-embedded tissues of 30 normal oral mucosa (NOM), 50 OSF cases and 105 OSCC-SMF. The immunohistochemistry was carried out to evaluate the expression of Ki67, CD105 and α-SMA antigen.RESULTS:Ki67 labelling index (LI), CD105 and α-SMA expression showed increasing trend from NOM, low-risk epithelial dysplasia (LRED), high-risk epithelial dysplasia (HRED), well-differentiated squamous cell carcinoma (WDSCC), moderately differentiated squamous cell carcinoma to poorly differentiated squamous cell carcinoma. However, there was no significant difference of α-SMA expression between HRED and WDSCC. In OSCC-SMF, Ki67 LI, CD105 and α-SMA were significantly higher in advanced clinical TNM stage, metastasis and less than 3 years patient survival as compared with early clinical TNM stage, non-metastasis and 3 years or more patient survival.CONCLUSION:Ki67 LI, α-SMA and CD105 expression alone or together correspond with the disease progression model of SMF. Hence, expression of these markers can be used as a predictive marker of clinical outcome of OSCC-SMF.
Aim: To assess the prevalence of oral findings in diabetic and nondiabetic chronic renal failure (CRF) patients receiving hemodialysis (HD). Materials and methods: This study was conducted on 144 CRF patients undergoing HD therapy. They were further classified into diabetic and nondiabetic groups and also according to the duration of CRF. An oral examination was performed, searching for CRF-associated oral findings, along with due considerations to duration of CRF. Results: The oral manifestations were found to be higher in diabetic CRF patients (97.14%) relative to nondiabetic CRF patients (89.18%). The diabetic group exhibited a significantly higher number of patients with poor oral hygiene index (p = 000), uremic fetor (p = 0.005), unpleasant taste (p = 0.009), dry-fissured lips (p = 0.002), and pale mucosa (p = 0.019) than the nondiabetic group. The oral manifestations were significantly higher in CRF patients of more than 24 months' duration. Conclusion: The CRF HD patients with diabetes mellitus exhibited a higher risk of oral uremic manifestations including uremic fetor, unpleasant taste, pale mucosa, and dry-fissured lips than nondiabetics. The oral health status of CRF HD patients becomes worse with the increase in the duration of CRF. Clinical significance: Oral health status is often a neglected aspect in CRF patients. It should be given prime importance for CRF patients receiving HD to improve the quality of life. Keywords: Chronic renal failure, Diabetes, Hemodialysis, Oral manifestations.
