ABSTRACT
Objective: To study and detect immunohistochemical expression of Estrogen Receptors, Progestrone Receptors and HER-2/neu Receptors in Endometrial Carcinoma [EC] and to find their associations with histological types, grades and stages of the tumor
Methods: A cross sectional study of one year duration from January 2016 to January 2017 was conducted at Histopathology department of Army Medical College, Rawalpindi. A non-probability purposive sampling technique was used to include 56 cases of EC. The specimens were tested for ER, PR and HER-2/neu expression using immunohistochemical analysis. Data was analyzed in SPSS and the significance of association of expression of the receptors with histological types, grades and stages of the tumor was assessed
Results: Significant association of Her-2/neu overexpression with histological types and grades of EC was seen, whereas the association of ER and PR expression with histological types, grades and stage of EC was statistically insignificant
Conclusion: It is suggested that EC showing over expression of HER2/neu with immunohistochemistry may be treated with anti HER-2/neu treatment with better chances of survival and decreased post-treatment morbidity
ABSTRACT
Agents of choice may be introduced in to the mouth via dental restorations, but this concept is only in embryonic stages and needs to be explored, modified, controlled and gauged to make it useful. This study aims at indicating the common therapeutic agents that are being delivered via dental restorations, modern restorative materials successfully delivering agents, and methods of agent incorporation; elaborating the potential for future use of such systems. Relevant publications from the last fifty years were included by searching 'dental restorations', and 'drug delivery systems' via [Mesh terminology]. Specific exclusion and inclusion criteria were set. It was found that the arena of drug delivery via dental restorations seems to be restricted to fluoride, the most commonly delivered agent via restorations. Glass ionomer cements including resin modified GICs; composites including compomers, and nanocomposites; and to some extent amalgam are the materials being researched upon. Although most research surrounds systems that rely upon recharge, modern microcapsules have been designed that can be used to incorporate the agent into the restoration. There is a dearth of work been done on the factors affecting the delivery of agents. So far, the dicalcium phosphate anhydrous [DCPA] incorporated nanocomposite is the most promising fluoride-delivering restorative material with a competent blend of fluoride releasing and mechanical properties. DCPA-incorporated nanocomposite and ion impregnable microcapsules are new horizons for drug delivery using dental restorations
