    Background: Ameloblastoma is the most common clinically significant odontogenic tumor, known for its locally invasive potential and frequent recurrences unless treated radically. Endocan is a soluble proteoglycan which is reported to have prognostic implications in multiple human diseases and tumors. This study aims to describe the expression of endocan in ameloblastoma. Materials and methods: With immunoperoxidase method; tissue sections of formalin fixed-paraffin embedded blocks for ameloblastomas were stained with monoclonal antibodies to endocan, the localization of the endocan expression was examined and the resulting scores of the tissue sections were analyzed according to age, sex, site and tumor subtype. Results: endocan was found to be expressed in peripheral and central epithelial cells of ameloblastoma tumor islands and stroma to different extents; a selectively increased expression was noted in epithelial cells with acanthomatous differentiation. Tumor epithelial cells of plexiform subtype tend to have higher expression levels of endocan. However, the associations did not reach statistically significant levels. Conclusions: Endocan is expressed specifically in various populations of tumor epithelial cells and stromal elements of ameloblastoma. The prognostic significance of the expression needs to be clarified in further studies.

    Abstract J Oral Pathol Med (2010) 39: 681–686 Background: Osteosarcomas (OS) of the jaws are uncommon lesions that represent less than 10% of all skeletal OS. It has a behavioral pattern which is less aggressive than their long bones counterparts. This study performed an immunohistochemical comparison between jaws and long bones OS. Methods: The study involved 15 jaws and 15 long bones OS tissue samples for the period from 1986 to 2005. Age, sex, histologic subtypes and grades were recognized. The samples were immunohistochemically stained with monoclonal antibodies to Ki-67, P53 and vascular endothelial growth factor (VEGF). Results: The mean age of the patients with jaw OS was a decade higher than that of long bones OS. A slight male predominance in jaw OS was found (1.14:1), which was more pronounced in long bones OS (2:1). The chondroblastic subtype was the predominant in jaws (66.66%), whereas (60%) of long bones OS were of osteoblastic subtype. The Ki-67 labeling index and the VEGF expression were significantly higher in long bones as compared with jaws OS, whereas there was no significant difference regarding the P53 expression between jaws and long bones OS. Conclusions: Jaws and long bones OS bear a comparable cell cycle dysregulation when quantified with P53 immunostaining, whereas the long bones OS have a higher proliferative and angiogenic capacity than their jaw counterparts when evaluated with Ki-67 and VEGF immunoexpressions respectively.

    ABSTRACT: BACKGROUND: Matrixmetalloproteinases (MMPs) are a class of matrix basement membrane degrading enzymes which were shown to be associated with metastases in several human tumors. OBJECTIVE: This study is aimed to investigate the potential effect of MMP-9 in imparting the frequently reported different behavioral pattern between jaws and long bones osteosarcomas. METHODS: Tissue blocks of ten cases of jaws osteosarcomas and another ten of long bones osteosarcomas were collected and stained immunohistochemically with monoclonal antibodies to MMP-9. RESULTS: The majority of cases (70%) were positive for MMP-9 expression which indicates a role in tumor spread, however; there was no significant difference between the sites. CONCLUSION: The study indicates that MMP-9 is probably not involved in the biologic differences between jaws and long bones osteosarcomas. KEYWORDS: jaw osteosarcoma, matrixmetalloproteinase-9

    Abstract Background: In recent years, the immediate loading of dental implants has become more accepted as a standard protocol for the treatment of the edentulous area. Success in implant dentistry depends on several parameters that may improve phenomenon of osseointegration and new bone formation in close contact with the implant. The aim of study was to evaluate the effect of strontium chloride coating of screw shape commercially pure titanium dental implant osseointegration at bone - implant interface by histomorphometric analysis and compare with hydroxyapatite coating at 2 time periods (2 weeks and 6 weeks). Materials and methods: Electrophoretic Deposition Technique (EPD) was used to obtain a uniform coating layer on commercially pure titanium screws. The tibia of 4 white New Zealand rabbits was chosen as implantation sites. Each tibia of rabbit received two screws, one strontium chloride coated and one hydroxyapatite coated and a total 30 histological sections were obtained for each coating material in each period of time. Histomorphometric analysis was performed to measure new bone formed ratio between implant and original bone, after 2 and 6 weeks healing periods. Results: There was increased in new bone formation ratio for the strontium chloride coated implants than hydroxyapatite coated implants and over the two periods of time. There was an increase in the new bone formation ratio at bone-implant interface with time. Conclusion: Coating commercially pure titanium implant with strontium chloride was more efficient in increasing osseointegration at bone implant interface than hydroxyapatite , which was demonstrated by higher new bone formation and maturation at the two periods of time 2 weeks and 6 weeks after implantation. Keywords: Histomorphometric, commercially pure titanium, strontium chloride, hydroxyapatite.

    Abstract Despite behavioral mimicry of ameloblastoma (AB) and basal cell carcinoma (BCC), they are classified at 2 extremes within pertinent WHO classifications with respect to benign and malignant designation. This study aims to appraise the current allocation of AB in the classification through an immunohistochemical comparison of some aspects of behavior with BCC. Sections from retrospectively retrieved formalin-fixed, paraffin-embedded tissue blocks of AB (n = 37) and BCC (n = 34) were comparatively examined for the immunohistochemical expression for Ki-67, Bcl-2, MMP-2, MMP-9, CD31, and D2-40 monoclonal antibodies. No statistically significant differences between the tumors were found regarding the immunoexpressions of Bcl-2 (P = .252), CD31 microvessel density (P = .895), lymphatic vessel density (P = .642), and MMP-9 stromal expression (P = .083). MMP-2 expression was significantly higher in epithelial and stromal regions of AB (P = .009 and P = .001, respectively), whereas Ki-67 and MMP-9 epithelial expressions were significantly higher in BCC (P < .000 and P = .026, respectively). Within the studied immunohistochemical attributes for tumor behavior, the study accentuated the overall behavioral mimicry of the tumors and indicated that BCCs surmount ABs by the proliferative rate only.

    Background: techniques of image analysis have been used extensively to minimize interobserver variation of immunohistochemical scoring, yet; image acquisition procedures are often demanding, expensive and laborious. This study aims to assess the validity of image analysis to predict human observer’s score with a simplified image acquisition technique. Materials and methods: formalin fixed-paraffin embedded tissue sections for ameloblastomas and basal cell carcinomas were immunohistochemically stained with monoclonal antibodies to MMP-2 and MMP-9. The extent of antibody positivity was quantified using Imagej® based application on low power photomicrographs obtained with a conventional camera. Results of the software were employed to predict human visual scoring results with stepwise multiple regression analysis. Results: the overall prediction of epithelial score depicted as r square value was 0.26 (p< 0.001) which was obviously higher than that of stromal score (0.10; p< 0.01). Epithelial and stromal MMP-2 score prediction was generally higher than that of MMP-9. Collectively, ameloblastomas had a more efficient score prediction compared to basal cell carcinomas. Conclusion: there is a considerable variability in the prediction capacity of the technique with respect to different antibodies, different tumors and cellular versus stromal score.

    Abstract This retrospective study aimed to assess the clinical features, associated risk factors and mortality rate in a group of Iraqi patients with Rhino-cerebral mucormycosis (RCM). The medical records of sixteen consecutive cases of RCM were reviewed retrospectively. Biopsies from the patients were referred to the Oral Pathology Laboratory at the College of Dentistry/University of Baghdad for histopathologic examination to confirm the diagnosis during the period from 2010 to 2019. The patients age ranged from 20 to 80 years with an average of 54.38 years. Fourteen (87.5 %) of the patients were males and 15 (93.75 %) were uncontrolled diabetics. The diagnosis was made by clinical and radiographic examination and confirmed by histopathological evaluation. All patients presented with an exposed intraoral necrotic bone and oro-nasal and antral fistulae. Follow up information was available for a minimum of six months, during which; two patients (12.5 %) were deceased within the review period. Base on this cohort of subjects, RCM is more common among males. Diabetes mellitus constitutes a significant risk factor for this infection. The presences of necrotizing maxillary lesion with fistula tract in RCM could be the reason for lower mortality rate in comparison to other mucormycosis variants. This difference in outcome could be explained by the early presentation, histopathological diagnosis and treatment of the cases.
