ABSTRACT
Introduction: WHO defines it as a ‘‘carcinoma within which there are some elements resembling a squamous cell carcinoma that are admixed with a spindle cell component. Spindle cell carcinoma is an uncommon poorly differentiated type of SCC com- prising up to 3% of SCC and it is also known as sarcomatoid carcinoma which is a rare biphasic malignant neoplasm. . Case Report: A 20 year old female patient complains of pain and growth in lower front teeth region since 3 months and gave a history of growth 2yrs back in the front teeth region for which she has been operated but it has recurred again. Discussion: The histological features mimicked other connective tissue sarcomas & spindle cell malignancies at light micro- scopic level. Hence, after undergoing immunohistochemistryA careful study based on clinical, radiological and histopathologi- cal and immunohistochemical examination was done and a final diagnosis of spindle cell carcinoma was given.
ABSTRACT
Diabetic nephropathy has become a leading cause of end stage renal failure worldwide. To develop Complementary and Alternative Medicine for the treatment of diabetic nephropathy, the present study investigated the protective effects of methanolic extract of Bougainvillea spectabilis (MEBS) in streptozotocin-induced diabetic nephropathy. In this study, diabetes was induced by a single injection of streptozotocin (STZ, 45 mg/kg, i.p.) in rats. STZ diabetic rats were treated with oral doses of MEBS (200 and 400 mg/kg) for 8 weeks. At the end of the experimental period body, kidney weight, blood glucose levels, serum and urine parameters were investigated. Antioxidant enzymes and lipid peroxide levels were determined in the kidney along with histopathological examination of the same. MEBS significantly increased body weight, lowered blood glucose levels and ameliorated kidney hypertrophy index in the STZ-diabetic rats. The extract also decreased the levels of creatinine, blood urea nitrogen, total cholesterol, triglycerides, advanced glycation end products and albumin in serum and urine, respectively. MEBS significantly increased the antioxidant parameters in the kidney. Histological evaluation revealed that MEBS treated STZ-diabetic rats demonstrated reduced vacuolar degeneration of tubules; periodic acid Schiff base (PAS) positivity staining intensity in glomeruli and basement membrane thickening. Present findings provide experimental evidence that MEBS has potential antioxidant, antihyperglycemic and anti-glycation activities which might be helpful in slowing the progression of diabetic nephropathy.
ABSTRACT
Community water fluoridation is widely used worldwide and its role in preventive dental health care is well established. However, there is sufficient evidence of the ill effects of excessive fluoride content in water, causing skeletal and dental fluorosis. Alongside, there was also extraskeletal and dental manifestations of excessive fluorides reported. They include the effect on thyroid function, but the literature regarding this is sparse. Aim: The present systematic review aims to analyze the data from controlled studies about the effect of fluoride on thyroid function. Materials and Methods: A systematic literature search was performed using PUBMED, MEDLINE, EMBASE, COCHRANE Library, EBSCO search, and the internet search, with language restriction to English. The search included published studies which dealt with the association of fluorine with hypothyroidism, from January 1981 to November 2015. Literature search was done using keywords: fluoride and hypothyroidism, dental fluorosis and thyroid disorders, systemic fluorosis and thyroid disease, excessive water fluoridation and hypothyroidism, thyroid and fluoride, fluorosis and its adverse effects. Results: Out of 166 publications, related to search strategy, 37 full articles which were related with the association of fluoride and hypothyroidism were acquired for further inspection. Out of the 37 articles, 10 articles met the inclusion criteria. The data were extracted and placed in an excel sheet and were analyzed. The analysis suggested a positive correlation of excess fluoride and hypothyroidism. Conclusion: The present systematic review suggests a positive correlation between excess fluoride and hypothyroidism. This calls the need for further well-controlled studies in this otherwise emerging alarming issue. It also calls for considerable community network through health informatics for problem sensitization.
