Background: Understanding the association of risk factors to adverse drug reactions is very important to all healthcare professionals for the development of appropriate preventive strategies for better health care. Objectives: To identify and evaluate the risk factors associated with adverse drug reactions developed in the hospitalized patients of different departments. Methods: A prospective-retrospective study was conducted in a tertiary care hospital for a period of twenty two months, with a specific criterion. Multiple logistic regression analysis was used. Risk factors included provisional diagnoses, suspected drugs which were classified according to ICD-10 classification and therapeutic classification respectively and also subjects’ age groups and gender were included. Results: A total of 204 cases’ were identified with adverse drug reactions during the period of study for which 1:1 ratio of controls were taken. During the study 175 subjects developed single ADRs (adverse drug reactions) and 29 had multiple ADRs. Causality assessment and severity of reactions were evaluated by using standard scales. Greater association to ADR were shown in the age group of...

Chenopodium album (sub sp. striatum) is a folk and nutritious medicine belongs to Chenopodiaceae family and widely used as antimicrobial agent. The aim of this study is to evaluate the in vitro antibacterial potential against multidrug-resistance (MDR) bacteria isolated from clinical spicemens, antioxidant activity, total phenolic and total flavonoids content of crude ethanolic extract and nine different fractions of C. album (sub sp. striatum). The in vitro antibacterial activity was evaluate against eight multidrug-resistant bacteria based on minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC), agar well and disk diffusion methods. Antioxidant property was evaluated by 1, 1-diphenyl-2-picryl-hydrazyl radical scavenging activity. The total phenol contents were measured by Folin-Ciocalteu and AlCl3 assays. Our results showed that MeOH: H2O with 80:20 ratio (most polar) fraction had the highest antimicrobial effect on eight multidrug-resistant bacteria (MIC: 0.15-2.5 mg/ml, MBC: 0.31-5 mg/ml and had highest inhibitation zones (well: 24.33±0.57 mm and disk: 26.33±1.53 mm). In antioxidant assay, MeOH: H2O fraction also exhibited the highest radical scavenging activity [Antioxidant activity = 95.1±2.13...

Background: The coronoid process of mandible is thin flat triangular process from the ramus of the mandible. This varies in the shapes and size. It gives attachment to two main muscles that is temporalis and masseter muscle. The coronoid process is the favourable donor site. A Coronoid process graft can be used for alveolar defects repair, orbital floor repair, maxillary augmentation, repair of non-union fracture of mandible. These grafts can be widely used in the reconstruction of osseous defects in oral and maxilla-facial region. Aim of the Study: This study is done to find out the variation in shape of coronoid process of mandible, Intercoronoid distance, coronoid- condylar distance and the length and breadth and thickness of the coronoid process of mandible. Methods: The study was done on the 100 dry human mandibles from the osteology bank of Saveetha medical college and hospital. The distance was measured using the digital vernier callipers and the values were analysed. Results: This study is useful for the maxillofacial surgeon and this useful...

Periodontal dressings were widely used after flap surgery to protect the surgical site since long. This study compared polyether urethane dimethacrylate resin based Barricaid dressing and non-eugenol based periodontal dressings in the perspective of pain, esthetics and patient acceptance using a randomized split-mouth study design. Fifteen patients coming to the Department of Periodontics at ITS Dental College and diagnosed as a case of generalized chronic periodontitis were selected. Total 30sites (2 sites in each patient) requiring the flap surgery were selected and contralateral sites in each patient were randomly allocated into two groups. At baseline plaque index, Modified gingival index were recorded. In group-1 non-eugenol dressing and in group-II light cured periodontal dressing were applied to secure the surgical sites after flap surgery. At day1,2 and 3 pain and discomort was assessed using Numeric Pain Rating Scale.(NPRS) After 7 days patients were recalled for removal of dressing, recording the indices and asked to fill a questionarrie regarding the patient acceptability. Collected data were subjected to statistical analysis and non-significant...

Objective: Enhancement of oral bioavailability of poorly water soluble drugs is the most challenging aspects of drug development. It is very important to find appropriate formulation approaches to improve the aqueous solubility and bioavailability of poorly aqueous soluble drugs. Ezetimibe is a new lipid lowering agent in the management of hyper-cholesterolemia. The drug is water-insoluble, lipophilic, and highly permeable. Therefore, bioavailability of ezetimibe may be improved by increasing its solubility. Method: The aim of the present study was to improve the solubility and dissolution rate of Ezetimibe by preparing microspheres by spray drying technique using HP β-cyclodextrin. Ezetimibe microspheres containing different ratios of HP- β-cyclodextrin were produced by using Propanol and water (50:50) as a solvent system. The prepared formulations containing different ratios of Ezetimibe and HP β-cyclodextrinwere evaluated for solubility and in-vitro dissolution. The prepared formulations were characterized by differential scanning calorimetry (DSC), X-ray diffraction spectroscopy (XRD), fourier transform infra-red spectroscopy (FTIR) and scanning electron microscopy (SEM). Dissolution profile of the prepared spray dried microspheres was compared with...
