Evaluation of the relationship between the expression of AgNOR and Ki67 with the recurrence rate in central granulomatous giant cell lesions: A case-control.

OBJECTIVES: Giant cell granuloma is a local nonneoplastic lesion that is divided into two categories, based on its site of occurrence: Central and peripheral giant cell granuloma. Central giant cell granuloma is an intraosseous lesion that has a tendency to recure even in surgically treated cases. Several studies have proven that there is an association between different lesions clinical behavior and their histological features. The aim of this study was to evaluate the expression of AgNOR and Ki67 in lesions with and without recurrency. MATERIAL AND METHODS: Files and records of 35 patients who had been histologically diagnosed with central giant cell granuloma were investigated. Histological features were studied after performing AgNOR staining and Ki67 marker. The data were analyzed by chi-square, Fisher, and T-test. RESULTS: Acquired data indicated that the count of AgNOR staining and Ki67 marker was significantly higher in lesions with recurrency than the lesions with no recurrency. The same results were attained from Ki67 intensity. CONCLUSION: The current study indicated that AgNOR staining and Ki67 marker have prognostic value in predicting recurrency of central giant cell granuloma lesions.

Evaluation of copper salivary level in oral squamous cell carcinoma, occupationally copper exposed, and its normal population and its association with cytomorphologic changes of oral mucosa.

Background: Oral squamous cell carcinoma (SCC) is one of the most common malignancies in oral cavity. Hence, presenting methods for early diagnosis and find the etiologic factors of oral SCC are important. Saliva analysis can be used to discover various conditions because of its noninvasive methods. Copper as a useful metal has been used by men since ancient times. The level of copper increases when the cancerous changes occur in addition to biopsy, an alternative method for examining oral lesions is exfoliative cytology. The primary objective of this study was to determine the salivary copper level and cytomorphologic changes of oral mucosa among three study groups. Materials and Methods: This cross-sectional study included 15 individuals with oral SCC, 15 workers exposed to copper, and 15 healthy individuals. Saliva samples were collected and analyzed by atomic absorption spectrophotometer. The exfoliative smears were prepared by brush biopsy and stained by Papanicolaou and argyrophilic nucleolar organizer region (AgNOR) staining methods. Data analysis using one-way ANOVA and Kruskal-Wallis test. P < 0.05 was considered significant. Results: There was a significant difference in mean salivary copper (P = 0.008), cytomorphology of oral mucosa, and AgNOR among the three groups (P < 0.001). Conclusion: The results suggested that occupational exposure to copper increases the salivary levels of this element and causes changes in mucosal cells. Since this increase was very high and evidence of nuclear activity was seen in this group and in oral SCC patients, exposure to copper should be considered an important risk factor for oral mucosal changes.

Peripheral giant cell granuloma as a sign of hyperparathyroidism in a patient under hemodialysis: A case report and review of literature.

Peripheral giant cell granuloma (PGCG) is a benign reactive exophytic oral lesion that originates from the periosteum or the periodontal ligament. It exclusively develops on the gingiva or alveolar mucosa. Hyperparathyroidism (HPT) is a possible etiology for its development. HPT is an endocrine disorder characterized by increased secretion of the parathyroid hormone (PTH). This case report describes a case of recurring PGCG in a patient diagnosed with secondary HPT after paraclinical assessment.

Oral health-related quality of life in patients with oral squamous cell carcinoma: A case-control study.

Background: The prevalence of oral squamous cell carcinoma (OSCC) has increased in recent years. With the development of various treatments, the mortality rate has decreased and more people are living with the consequences of the disease and its treatment, which can have a great impact on the quality of life. Some questionnaires measure the impact of the disease on daily activities and patient behavior. In this study, the oral health-related quality of life (OHRQOL) was assessed through the Oral Health Impact Profile (OHIP)-14 questionnaire between the OSCC patient and control groups. Materials and Methods: In this cross-sectional study, the OHIP-14 questionnaire was given to 51 OSCC patients who had completed the treatment at least 6 months before participating in this study and 51 healthy individuals, and we used the Chi-square test, independent sample t-test, one-way ANOVA, and linear regression in three models. P = 0.05 was considered statistically significant. Results: The mean age of patients was 55.86 ± 15.04 years and the control group was 54.96 ± 14.08 years. Women made up 51% of patients. The mean OHIP score was 22.84 ± 11.42 in the patient group and 17.92 ± 9.23 in the control group, which indicates a significant (P = 0.005) difference between the two groups according to the independent sample t-test. Conclusion: The OHRQOL of patients has significantly decreased compared to the control group. Surgery had the lowest quality reduction, and combined surgical treatment with radiotherapy and chemotherapy had the highest reduction in the OHRQOL. It is recommended to have regular follow-up sessions and to have a proper diet during and after treatment.

Central unilocular mucoepidermoid carcinoma of the mandible: A case report and literature review.

Mucoepidermoid carcinoma (MEC) is the most common salivary gland malignancy. Central MEC (CMEC) is a rare tumor which affects women more than men and is more common in the mandible. Most cases are histologically classified as low-grade tumor and radiographically appear as well-defined unilocular or multilocular radiolucent lesion, although this tumor causes destruction and metastasis to other organs. In this article, we present a rare case of CMEC in a 47-year-old woman with unilocular radiolucent lesion of the mandible. Early and accurate diagnostic approach in all lesions with clinical/radiographical bland appearance is important, and all possibilities such as a malignant lesion should be considered.
