Expression of anti - Apoptotic survivin in odontogenic keratocyst, adenomatoid odontogenic tumor and ameloblastoma.

Background: The process of odontogenesis is complex involving epithelial-mesenchymal interactions, along with the molecular signalling pathways triggering the initiating process. The triggering factors and cells precisely involved in the pathogenesis of odontogenic cysts and tumors are unknown. There is a vast array of biomarkers used to stain different sites, thereby helpful in diagnosing and evaluating the prognosis of these cysts and tumors. In the following study, Anti Apoptotic survivin expression patterns were assessed quantitatively in 48 samples (12 each) of Reduced Enamel Epithelium, Adenomatoid Odontogenic Tumor, Odontogenic Keratocyst and Ameloblastoma. Aim: The Aim of this study is to assess the anti-apoptotic survivin expression in Reduced Enamel Epithelium, Adenomatoid odontogenic tumour, Odontogenic Keratocyst and Ameloblastoma. Materials and Methods: The present study is carried out with 12 samples in each group. Routine hematoxylin and eosin staining was performed for confirmatory diagnosis. Later Immunohistochemistry was performed using survivin antibody. Survivin protein expression was analyzed using the parameters like location, intensity, percentage of cells positivity with survivin protein and extent of staining. With the help of Olympus BX 43 microscope, with ProgRes microscope camera, the 48 slides obtained were examined. The region of interest was selected in each slide and number of cells positively stained was counted. Data was analyzed using SPSS software version 23. Descriptive for scale data, results were analysed by using ANOVA with Chi-square test for intergroup comparison. Results: The results showed significant P value <0.05. Expression of survivin was highest in Ameloblastoma, followed by Odontogenic keratocyst, Adenomatoid odontogenic tumor, and Reduced Enamel Epithelium. Conclusion: Survivin was involved in the inhibition of apoptosis as well as the detailed understanding of the biological behaviour of odontogenic cysts and tumours, thereby increasing therapeutic approaches.

Kangaroo Mother Care implementation research to develop models for accelerating scale-up in India and Ethiopia: study protocol for an adequacy evaluation.

INTRODUCTION: Kangaroo Mother Care (KMC) is the practice of early, continuous and prolonged skin-to-skin contact between the mother and the baby with exclusive breastfeeding. Despite clear evidence of impact in improving survival and health outcomes among low birth weight infants, KMC coverage has remained low and implementation has been limited. Consequently, only a small fraction of newborns that could benefit from KMC receive it. METHODS AND ANALYSIS: This implementation research project aims to develop and evaluate district-level models for scaling up KMC in India and Ethiopia that can achieve high population coverage. The project includes formative research to identify barriers and contextual factors that affect implementation and utilisation of KMC and design scalable models to deliver KMC across the facility-community continuum. This will be followed by implementation and evaluation of these models in routine care settings, in an iterative fashion, with the aim of reaching a successful model for wider district, state and national-level scale-up. Implementation actions would happen at three levels: 'pre-KMC facility'-to maximise the number of newborns getting to a facility that provides KMC; 'KMC facility'-for initiation and maintenance of KMC; and 'post-KMC facility'-for continuation of KMC at home. Stable infants with birth weight<2000 g and born in the catchment population of the study KMC facilities would form the eligible population. The primary outcome will be coverage of KMC in the preceding 24 hours and will be measured at discharge from the KMC facility and 7 days after hospital discharge. ETHICS AND DISSEMINATION: Ethics approval was obtained in all the project sites, and centrally by the Research Ethics Review Committee at the WHO. Results of the project will be submitted to a peer-reviewed journal for publication, in addition to national and global level dissemination. STUDY STATUS: WHO approved protocol: V.4-12 May 2016-Protocol ID: ERC 2716. Study implementation beginning: April 2017. Study end: expected March 2019. TRIAL REGISTRATION NUMBER: Community Empowerment Laboratory, Uttar Pradesh, India (ISRCTN12286667); St John's National Academy of Health Sciences, Bangalore, India and Karnataka Health Promotion Trust, Bangalore, India (CTRI/2017/07/008988); Society for Applied Studies, Delhi (NCT03098069); Oromia, Ethiopia (NCT03419416); Amhara, SNNPR and Tigray, Ethiopia (NCT03506698).

Salivary alkaline phosphatase levels speak about association of smoking, diabetes and potentially malignant diseases???

BACKGROUND: Alkaline phosphatase (ALP) is a hydrolase intracellular enzyme participating in the metabolic processes of cells. Rise in salivary ALP (S-ALP) levels reflects inflammation and destruction of healthy tissues suggesting it as a clinical biomarker. S-ALP is used in analyzing the severity of the disease occurrence in smokers and nonsmokers who are diabetic and nondiabetic. S-ALP levels are analyzed using autoanalyzer in 40 patients who visited our department. AIMS AND OBJECTIVES: To determine the levels of S-ALP in diagnosing potentially malignant conditions and debilitating diseases in early stages of inflammation and altered cellular metabolism. MATERIALS AND METHODS: The study groups include: (1) Group A - 10 smokers who are diabetic. (2) Group B - 10 smokers who are nondiabetic. (3) Group C - 10 nonsmokers who are diabetic. (4) Group D - 10 nonsmokers and nondiabetic as control. Unstimulated saliva samples are collected and run in auto-analyzer with ALP enzyme reagent to analyze ALP levels. Comparison is made between all the four groups. RESULTS: Results were statistically significant with increased activity of ALP levels in saliva from Group A when compared to Group D. The results are Group A > Group B > Group C > Group D. The results also revealed significant raise in levels of ALP levels in saliva from smokers when compared to diabetes. Thus explaining adverse effects of smoking. CONCLUSION: S-ALP can be considered to be the biomarker for evaluating adverse effects of smoking, diabetes and other debilitating diseases in early stages.

Efficacy of Specific Plant Products on Microorganisms Causing Dental Caries.

INTRODUCTION: Dental caries and periodontal diseases are the most common oral diseases seen globally, both in developed and developing countries. Oral microorganisms that is gram positive and gram negative bacteria are known to be involved in causation of these diseases. Nowadays commercially available dentrifices and mouth rinses are known to contain ingredients that can alter the oral microbial flora and have undesirable side effects such as vomiting, diarrhoea, disarrangement of oral, intestinal flora and tooth staining. Naturally available plant products are known to be less harmful with fewer side effects and also economical for the patient. AIM: The aim of this study was to determine the antimicrobial properties of 10 naturally available plant products against oral microorganisms causing caries and to check the efficacy of these products in-vitro and to use these in mouth washes and dentrifices. MATERIALS AND METHODS: Sample of caries material was scrapped out from the extracted teeth and transferred to liquid broth, streaked over the agar media to allow for the growth of microorganisms. Plant products like clove oil, neem, ginger-garlic paste, tea tree oil, ginger, garlic, cinnamon oil, green tea, eucalyptus oil and turmeric were used. Antimicrobial efficacy of these products, was estimated by measuring zones of inhibition in the nutrient agar media. RESULTS: Clove oil was the most effective of all products against microorganisms causing caries with zone of inhibition - 30mm followed by ginger-garlic paste - 25mm, Neem - 15mm, tea tree oil - 15mm. CONCLUSION: Based on the above results, it can be inferred that these natural products have the maximum efficacy against microorganisms and can be recommended in dentifrices, mouth rinses, topical gels, etc.
