A prospective observational study of prescription pattern of drugs used in the treatment of osteoarthritis in a tertiary care hospital

Background: Treatment of Osteoarthritis aims at reducing pain and improving mobility. NSAIDS are commonly prescribed for symptomatic relief despite well documented adverse effects. Paracetamol with its better safety profile is recommended as the initial analgesic of choice. Osteoarthritis has significant socio-economic impact on the patients and not many studies are available to reflect upon the prescription pattern of drugs in Osteoarthritis. Hence, this study was chosen to generate important feedback to the clinician. The objectives of the study were to study the prescribing pattern of drugs used in the treatment of Osteoarthritis in Tertiary care hospital.Methods: Prescription for 300 osteoarthritis patients collected cross-sectional for 6 months from orthopedic out-patient department were analyzed.Results: 60% of females were affected. Average age of study was 56.46+/- 7.4 years. Knee joint (87.33%) was most commonly affected joint. Average number of drugs prescribed was 2.62 +/- 0.76. Out of 786 drugs prescribed 45.8% were NSAIDs. Paracetamol was underutilized.Conclusions: Paracetamol was underutilized while other NSAIDs were over prescribed

Causality assessment and the severity of the adverse drug reactions in tertiary care hospital: a pharmacovigilance study

Background: Adverse drug reactions (ADRs) constitute a major clinical problem in terms of human suffering and increased health care costs. To study the adverse drug reactions reported in a tertiary care hospital and study of causality assessment and severity of adverse drug reaction (ADR) cases reported.Methods: A prospective observational study was conducted as part of pharmacovigilance program over 12months between September 2015 and August 2016. Adverse drug reactions reported from hospital were filled into Suspected ADR - CDSCO forms and submitted to pharmacovigilance unit. Causal relationship was assessed and categorized by Naranjo’s algorithm and WHO - UMC causality scale. The severity of each ADR was assessed using Modified Hartwig and Siegel scale.Results: Total 120 cases were reported over 12 months. Among them, 66% were in males and 55% were in females. The majority of ADRs were due to antimicrobial agents (40.78%) followed by haematinics (12%) and anti-epileptics (10%). Maximum number of patients (30.25%) reported with dermatological manifestations. Highest number of ADRs was reported from the department of medicine (45%). As per Naranjo’s scale, 54% reports were assessed as probable and 46% classified as possible. Majority of cases were mild to moderate in severity.Conclusions: The pattern of ADRs reported in our hospital is similar with the pattern of studies conducted in other hospitals elsewhere. This study provides a database of ADRs due to commonly used drugs in our hospital, which will help clinicians for their optimum and safe use. Hence effective pharmacovigilance is required for the use of these drugs and their safety assessment

Analysis of Human Epidermal Growth Factor Receptor -2 Expression in Gastric Adenocarcinoma

Institution: Govt. Kilpauk Medical College, Chennai BACKGROUND: Gastric carcinoma is the fourth most common cancer in the world. It is a disease of elderly and more common in males. The poor prognosis of gastric tumour is due to late presentation, nonspecific symptoms and limitations in treatment options. An association between clinicopathological features and molecular markers would give a clue toward the relationship between them and hence provide us an extra tool to combat the high mortality. METHODS: A retrospective study was conducted in 100 patients with histopathologically proven gastric adenocarcinoma. In this study , expression of Immuno histochemical marker HER -2 in gastric adeno carcinoma was analysed and compared with various clinicopathological markers. RESULTS: Her -2 Overexpression was seen in 25% of total cases. Positivity for HER-2/Neu was present in 52% of moderately differentiated tumours, 28% of well differentiated tumours and 20% of poorly differentiated tumours CONCLUSION: Statistically significant correlation was found out between Her -2 receptor over expression and different histological grades of gastric adenocarcinoma. Her- 2 receptor over expression is more common in well and moderately differentiated tumours than poorly differentiated tumours

Ameloblastic Fibroma Associated With Impacted 3rd Molar: A Case Report

Ameloblastic fibroma is an uncommon mixed neoplasm of odontogenic origin with a relative frequency between 1.5 – 4.5%. It can occur either in the mandible or maxilla, but predominantly seen in the posterior region of the mandible. It occurs in the first two decades of life. Most of the times it is associated with tooth enclosure, causing a delay in eruption or altering the dental eruption sequence. The common clinical manifestation is a slow growing painless swelling and is detected during routine radiographic examination. There is controversy in the mode of treatment, whether conservative or aggressive. Here we reported a 38 year old male patient referred for evaluation of painless swelling on the right posterior region of the mandible associated with clinically missing 3rd molar. The lesion was completely enucleated under general anesthesia along with the extraction of impacted molar

Synthesis, and biological screening of chloropyrazine conjugated benzothiazepine derivatives as potential antimicrobial, antitubercular and cytotoxic agents

A series of twenty new chloropyrazine conjugated benzothiazepines (22-41) have been synthesized with 58%–95% yields. The compounds were characterized by using different spectroscopic techniques including FT-IR, ¹H NMR, ¹³C NMR spectroscopy and mass spectrometry. The synthesized compounds (22-41) and their precursor chalcones (2-21) were evaluated for antitubercular and cytotoxic activities. Additionally, compounds 22-41 were also tested for antimicrobial activity. Among the chalcone series (2-21), compounds 7 and 14 showed significant antitubercular activities (MICs 25.51 and 23.89 µM, respectively), whereas among benzothiazepines (22-41), compounds 27 and 34 displayed significant antimicrobial (MICs 38.02 µM, 19.01 µM) and antitubercular (MIC 18.10 µM) activities. Compounds 7 and 41 displayed cytotoxic activities with IC₅₀ of 46.03 ± 1 and 35.10 ± 2 µM respectively. All the compounds were evaluated for cytotoxic activity on normal human liver cell lines (L02) and found to be relatively less selective towards this cell line. The most active compounds identified through this study could be considered as potential leads for the development of drugs with possible antimicrobial, antitubercular, and cytotoxic activities
