Purpose: To determine the levels of Vitamin D in children with myopia and to compare them with age matched controls. Study Design:  Case control study. Place and Duration of Study:  The study was conducted in Naseer Memorial Hospital, Dadhyal Azad Kashmir from March 2016 to March 2017. Material and Methods:  Two hundred patients were selected using convenient sampling technique and were divided two groups (group I Myopic and group II control). Myopia was labeled if after subjective refraction a Spherical Equivalent (SE) of −0.50 diopters (D) or more was found. Vitamin D levels were measured by radioimmunoassay technique with Diasorin SR® kit following the user’s manual. Vitamin D levels less than 20 ng/ml were considered Vitamin D deficient following the standards of American academy of pediatrics. The collected data was entered in the statistical package for social sciences (SPSS) version 21 for analysis. Independent t–test was used to determine the significant difference of means between controls and patients. P-values less than 0.05 were considered significant. Results:  Mean age of controls and myopes were 10.65 ± 3.9 and 10.20 ± 2.5 years respectively. Vitamin D levels in myopic children were found to be 14.95 ± 3.75 ng/ml and there was no significant difference in mean values of Vitamin D levels in myopic and control group. Conclusion:  We found no difference in Vitamin D levels of myopic and non myopic children and concluded that Vitamin D has no role in development or progression of myopia.

Background: Hypothyroidism was the diagnosed and treated as a result of health related quality of life issues. The aim of this study was that to evaluate the effect of IL-36 γ, Tg-Ab and TOP-Ab in the Hashimoto’s Thyroiditis (HT). Study design: This was a cross sectional study conducted at Rawal Institute of health sciences, Islamabad duration of study was six month, from April 2022 to September 2022. Methods: A total number of the patients was n=150 which divided into two group, control and HT group. To perform EISA for the estimation of free triiodothyronine 3, 4 (FT3, FT4), thyroid stimulating hormone (TSH), thyroid peroxidase antibody (TOP-Ab) and thyroid globulin antibody (Tg-Ab). The data was analyzed by SPSS 21. Results: The serum IL-36γ show correlation with the TOP-Ab and FT3 in HT. The IL-36γ was significantly higher in HT as compared to the control group; p<0.001**. The IL-36γ show significant negative correlation with TOP-Ab (<0.001**, r-0.126) and non- significant positive correlation with FT3 (0.321, r= + 0.28) in HT patients. The Tg-Ab was show non- significant correlation with IL-36 γ; (P<=0. 928, r = 0.323). Conclusions: IL-36 γ is diagnostic marker and show negative correlation with TPO-Ab in the patient serum of HT. Il-36 γ had significantly high in the HT patients. IL-36 γ may involve to the progression of pathogenesis and enhance the inflammatory responses. In HT, Tg-Ab was significantly reduced than TPO-Ab but both contribute to the production of thyroid hormones. Keywords: Interleukin, Thyroxin, Thyroid stimulating hormone, Peroxidase.

Background: Serum 25-Hydroxyvitamin D is a biomarker used to assess an individual's vitamin D status. Bone health, immune function, calcium and phosphate metabolism is crucially regulated by the vitamin D. Cardiovascular diseases (CVD) are the leading cause of death world widely. Many studies have shown that the vitamin D plays potential role cardiovascular diseases prevention. Study design: It is a prospective study conducted at Rawal Institute of health sciences, Islamabad for the duration of six months from July 2022 to December 2022. Material and Methods: The review board committee of the hospital approved the study. In the given study, a total of 300 patients were selected. All these patients were included in this study according to the inclusion criteria. The statistical analysis was conducted. The multivariable Cox regression analysis was done. The immunoassays analyzer was used for vitamin D status assessment. Results: The average age of the patients were ranging from 56 to 63 years and all of them were suffering from cardiovascular diseases. Different patterns like qualification, educational history with regard to awareness, Smoking patterns, Diabetic medications, and duration of cardiovascular diseases were considered in this study. Conclusion: Serum 25-hydroxyvitamin D concentrations and all-cause mortality are inversely related. The risk of all-cause mortality is lower in the participants with higher serum 25-hydroxyvitamin D concentrations than those with lower concentrations. Keywords: Hydroxyvitamin D and cardiovascular diseases.

Objective: Multidrug-resistant and pan-drug-resistant pathogens pose major challenges in the management of infections. Nanotechnology-based combination therapy is becoming more common, as it produces a synergistic antimicrobial effect. Study Design: Cross Sectional Study. Setting: Institute of Biogenetic Engineering (IBGE) Islamabad. Period: September 2015 to October 2017. Material & Methods: Silica nanoparticles were prepared by three different modifications using general Stober Method and the synthesized silica nanoparticles SiNPs were named as S1, S2 and S3. The synergism of Ciprofloxacin and Piperacillin-Tazobactam with a combination of silica nanoparticles was evaluated in LB grown culture to determine the sensitivity of Escherichia coli and pseudomonas aeruginosa. Results: The combined application of Ciprofloxacin and S1, S2 and S3 respectively retarded the growth of P. aeruginosa almost completely whereas E. coli showed minimal growth inhibition. Collective therapy of Piperacillin-Tazobactam with S1, S2 and S3 inhibits the normal growth pattern of both E. coli, P. aeruginosa as compared to the control. Conclusion: Combined application of silica nanoparticles and antibiotics inhibited the growth of MDR gram-negative bacteria in vitro.
