Background: Nutrition especially micro-mineral nutrients plays a major role in the etiology of chronic periodontitis. Serum levels of micro-mineral nutrients can be used as markers for the incidence of periodontitis and may also be used as indicators for dietary supplementation. Aims and Objectives: The aim of the study was to estimate the serum levels of Zn, Cu, Fe, and Mg of chronic periodontitis patients and normal healthy controls., to measure the clinical parameters (gingival index, probing pocket depth [PPD], and clinical attachment loss) in chronic periodontitis patients and normal healthy controls., to compare the levels of serum Zn, Cu, Fe, and Mg levels of chronic periodontitis patients and healthy controls and to correlate the levels of serum micronutrients with clinical parameters (gingival index, PPD, and clinical attachment loss) in chronic periodontitis patients and healthy controls. Materials and Methods: A total of 110 subjects, 55 subjects with chronic periodontitis and 55 healthy control subjects in the age group 35–65 years were selected for the study. Serum micronutrient levels of Cu, Fe, Zn, Mg, and the clinical parameters were measured. Results: Serum concentrations of Cu and Fe showed statistically significant increase and serum Zn and Mg showed a significant decrease in peridontitis patients as compared to normal healthy controls. Copper and Fe showed a significant positive correlation and Zn and Mg showed a significant negative correlation with clinical parameters (gingival index, PPD, and clinical attachment loss). Conclusion: The present study supports and extends the view that the assessment of serum mineral micronutrient can serve as possible biomarkers or indicators for an inflammatory condition like chronic periodontitis.
Introduction: Breast cancer is the second leading cause of cancer deaths in women after lung cancer. Breast cancer survival varies by racial and ethnic factors, stage at diagnosis, tumour grade, molecular subtypes and the treatment received. Molecular subtyping provides prognostic and predictive information about the risk of recurrence and is an essential tool in formulating guidelines in therapy. Aim: To identify the histopathological variants of Carcinoma (Ca) breast in women and to determine the various molecular subtypes by Immunohistochemistry (IHC). Materials and Methods: A cross-sectional study from January 2019 to December 2020 was done on 100 cases of invasive carcinoma breast at the Department of Pathology in a tertiary care center of Government Medical College, Ernakulam, Kerala. IHC was done on paraffin processed tissue sections of tumour using anti-Oestrogen Receptor (ER), anti-Progesterone Receptor (PR), anti-Human Epidermal growth factor Receptor 2 (HER2/ neu) and Ki-67 antibodies. Molecular subtypes of Luminal-A, Luminal-B, HER2 enriched and triple negative (basal-like) were determined. The association between molecular subtypes and tumour grade, size, stage was analysed using IBM Statistical Package for the Social Sciences (SPSS) version 21.0 software. Chi-square test used for categorical variables, p-value <0.05 assumed to be significant. Results: Total 100 female cases of invasive carcinoma breast with mean age 49.3±12.2 years were included. Histologic subtypes of carcinoma were: Invasive Ductal Carcinoma (IDC) of No Special Type (NST) (89%), Invasive Lobular Carcinoma (ILC) (1%), Invasive ductal with Lobular carcinoma (IDC-L) (1%), metaplastic (2%), papillary (4%), IDC with medullary like features (3%). Tumour size was pT1 in 27%, pT2 in 38%, pT3 in 33%, pT4 in 2%. Tumour grades were: grade-I (28%), grade-II (29%) and grade-III (43%). Lymph node metastasis was seen in 52% cases. Positive expression of Oestrogen (ER) in 46%, Progesterone (PR) in 38%, HER2/neu in 23% and low Ki-67 labeling index (<14%) in 32% cases were observed. The molecular subtypes were Luminal-A (32%), Luminal-B (14%), HER2 enriched (16%) and triple negative (38%) in the present study. Conclusion: The most common molecular subtype was triple negative. Luminal-A subtype was associated with lower histologic grade and non luminal subtypes were associated with higher histologic grades. To determine molecular subtypes, IHC is useful as a surrogate for molecular testing.
Introduction: Colorectal cancer (CRC) is a common cancer worldwide. It is the third most commonly diagnosed cancer in males and the second in females, with more than 1.4 million new cancer cases every year. Around 40,000 people will be effected by rectal cancer for every year, with a 65% survival rate from past 5-year were estimated. The age standardized rate (ASR) for CRC in India is low at 7.2 per 100,000 population in males and 5.1 per 100,000 populations in women. However overall incidence and survival rates were increased due to the screening and early detection. Materials and Methods: The proposed study is a prospective, hospital based, comparative cohort study including the cases admitted to Basavatarakam Indo American Cancer Hospital and Research Institute, Hyderabad, Telangana with clinical features and investigations suggestive of carcinoma rectum and fulfilling the inclusion criteria will be taken up for study. Patients considered as per inclusion criteria admitted in Basavatarakam Indo American Cancer Hospital and Research Institute, Hyderabad, Telangana were selected and the dosimetric data was collected from the TPS planning system and clinically relevant data was collected from the patient’s record from hospital digital interface system.
