Abstract Objective To investigate oxidative erythrocyte damage in dogs treated with different non-steroidal anti-inflammatory drugs. Material and methods Case-controlled prospective observational study using blood obtained from dogs presenting for lameness examinations or standard surgical procedures to a private referral clinic. Sampling was performed from April 2018 to July 2019. Groups comprised dogs receiving either metamizole (dipyrone) (22 dogs), carprofen (20 dogs) or meloxicam (20 dogs) for a minimum of 10 days. Dogs with gastrointestinal hemorrhage were excluded from the study. A complete hematological, as well as a basic biochemical profile were performed in every dog. Pappenheim stained blood smears were evaluated for eccentrocytes and brilliant cresyl blue stained smears for Heinz bodies. EDTA blood was frozen at –80°C immediately after sampling for measurement of superoxide dismutase and gluthathione peroxidase activity at an external laboratory. Hemoglobin concentration, superoxide dismutase and gluthathione peroxidase activities, reticulocyte count, eccentrocyte and Heinz body numbers were determined prospectively as key parameters for further statistical assessment with Kruskal-Wallis test and Dunn’s multiple comparisons test. Results Dogs receiving metamizole showed a significant increase in eccentrocyte (median 14.5/500 cells vs. 0/500 cells in the other groups, p < 0.0001) and reticulocyte number (median 191.4 × 109/l vs. 31.6–37.9 × 109/l, p < 0.0001) and a significant decrease in hemoglobin concentration (median 8.4 mmol/l vs. 10.1–10.5 mmol/l, p < 0.0003). No significant difference in superoxide dismutase and gluthathione peroxidase activities was observed between dogs receiving metamizole and the other groups. Heinz bodies were not found in any of the dogs. Conclusion Treatment with metamizole for 10 or more days resulted in decreased hemoglobin concentration, eccentrocytosis and reticulocytosis in dogs in this study. This might be a sign of increased oxidative damage caused by this drug. Clinical significance Prolonged metamizole therapy should be evaluated critically in patients already affected by severe illness or underlying anaemia.

ABSTRACT Aim To investigate the efficacy of using antibiotics in post endodontic treatment as a method to alleviate post-treatment pain. Materials and methods After completion of endodontic treatment 129 patients were randomly divided into two groups: Group A (65 patients) received Ibuprofen 400 mg one tablet before procedure and one tablet every 8 hours for the first day, then one tablet once indicated by pain. Group B (64 patients) received the same regimen as group A in addition to amoxicillin, clavulanic acid tablets (one tablet before the procedure, and then one tablet twice daily for a total of 3 days). Intensity of pain at 8 hours interval using visual analog scale (VAS) and total number of Ibuprofen tablets used was recorded by patients. Results Peak postoperative pain occurred at 16 hours posttreatment in both groups, there was a significant difference in the pain scale between the two groups in favor for group B over group A (3.8 vs 2.1 respectively). Pain scale was significantly lower in group B at 24, 32, 40, and 48 hours post-treatment with a p-value of < 0.05. The pain scale at 56, 64 and 72 hours were also less in group B, although could not show up as statistical difference. Patients in group A used statistically significant more Ibuprofen than patients in group B (486 vs 402). Conclusion Antibiotic prescription to manage post endodontic treatment pain results in less pain with less consumption of Ibuprofens. Clinical significance Pain management in endodontics is a real challenge, nonsteroidal anti-inflammatory drugs (NSAIDS) are used effectively in many patients to alleviate post endodontic pain. Nonsteroidal anti-inflammatory drugs may have adverse reactions or may be contraindicated. Short-term use of antibiotics to alleviate pain can be of clinical benefits in these patients.

Aspirin is unique among the nonsteroidal anti-inflammatory drugs in that it has both anti-inflammatory as well as cardio-protective properties. The cardio-protective properties arise form its judicious inhibition of platelet-derived thromboxane A2over prostacyclin, while its anti-inflammatory effects of aspirin stem from its well-established inhibition of prostaglandin (PG) synthesis within inflamed tissues. Thus aspirin and the other NSAIDs have popularised the notion of inhibiting PG biosynthesis as a common anti-inflammatory strategy based on the erroneous premise that all eicosanoids are generally detrimental to inflammation. However, our fascination with aspirin has shown a more affable side to lipid mediators based on our increasing interest in the endogenous control of acute inflammation and in factors that mediate its resolution. Epi-lipoxins (epi-LXs), for instance, are produced from aspirin’s acetylation of inducible cyclooxygenase 2 (COX-2) and together with Resolvins represent an increasingly important family of immuno-regulatory and potentially cardio-protective lipid mediators. Aspirin is beginning to teach us what nature knew all along – that not all lipid mediators are bad. It seems that while some eicosanoids are pathogenic in a variety of diseases, others are unarguable protective. In this review we will re-count aspirin’s colorful history, discuss its traditional mode of action and the controversies associated therewith, as well as highlight some of the new pathways in inflammation and the cardiovascular systems that aspirin has recently revealed.

SummaryPatients undergoing total hip or knee arthroplasty should receive anticoagulant therapy because of the high risk of venous thromboembolism. However, many are already taking non-steroidal anti-inflammatory drugs (NSAIDs) or acetylsalicylic acid (ASA) that can have antihaemostatic effects. We assessed the bleeding risk in patients treated with thromboprophylactic dabigatran etexilate, with and without concomitant NSAID or ASA. A post-hoc analysis was undertaken of the pooled data from trials comparing dabigatran etexilate (220 mg and 150 mg once daily) and enoxaparin. Major bleeding event (MBE) rates were determined and odds ratios (ORs) generated for patients who received study treatment plus NSAID (half-life ≤12 hours) or ASA (≤160 mg/day) versus study treatment alone. Relative risks were calculated for comparisons between treatments. Overall, 4,405/8,135 patients (54.1%) received concomitant NSAID and 386/8,135 (4.7%) received ASA.ORs for the comparison with/without concomitant NSAID were 1.05 (95% confidence interval [CI] 0.55–2.01) for 220 mg dabigatran etexilate; 1.19 (0.55–2.55) for 150 mg; and 1.32 (0.67–2.57) for enoxaparin. ORs for the comparison with/without ASA were 1.14 (0.26–5.03); 1.64 (0.36–7.49); and 2.57 (0.83–7.94), respectively. For both NSAIDs and ASA there was no significant difference in bleeding between patients with and without concomitant therapy in any treatment arm. Patients concomitantly taking NSAIDs or ASA have a similar risk of MBE to those taking dabigatran etexilate alone. No significant differences in MBE were detected between dabigatran etexilate and enoxaparin within comedication subgroups, suggesting that no increased major bleeding risk exists when dabigatran etexilate is administered with NSAID or ASA.Investigation performed at multiple centres participating in the RE-MODEL™, RE-NOVATE®, and RE-MOBILIZE® trials.

In almost all aerobic organisms, the superoxide dismutase (SOD) is considered as an important antioxidant enzyme regulating oxidative stress. Tetranychus cinnabarinus is an economically important polyphagous pest mite, which harms a variety of economic crops and ornamental plants. In the present study, the full-length cDNA sequences of cytoplasmic Cu/ZnSOD (TcSOD1), extracellular Cu/ZnSOD (TcSOD2) and mitochondrial MnSOD (TcSOD3) from T. cinnabarinus were cloned by combining RT-PCR and rapid amplification of cDNA ends (RACE). The corresponding open reading frames (ORFs) encode three putative polypeptides of 152, 232, 225 amino acid residues, respectively. These sequences share the conserved SOD functional domains, signature motifs and metal binding sites. Multiple alignment analysis revealed that cytosolic Cu/ZnSOD and mitochondrial MnSOD sequences are relatively conserved, while extracellular Cu/ZnSODs are more diverse. Phylogenetic analysis showed that SODs are organized into two major clades, corresponding to Cu/ZnSODs, and MnSODs. Cu/ZnSODs are subdivided into two branches, one being composed of cytoplasmic Cu/ZnSODs, and the other corresponding to extracellular Cu/ZnSODs. Expression profiles of the three genes were determined at different temperatures (4°C, 25°C, and 40°C) for 2 hours. The relative expression of TcSOD1, TcSOD2, and TcSOD3 were significantly down-regulated (0.344-, 0.287-, and 0.358-fold, respectively) at 4°C compared to 25°C (P<0.05). The relative expression levels of TcSOD1 and TcSOD2 genes were significantly down-regulated at 40°C (0.481- and 0.291-fold less than in the control group, respectively) (P<0.05), while there was no significant difference in the relative expression level of TcSOD3(P>0.05). Moreover, expression levels were altered after exposition to different acaricides. TcSOD1, TcSOD2, and TcSOD3 were significantly down-regulated (0.450-, 0.147- and 0.663-fold decreases, respectively) in the abamectin-treated group (P<0.05). TcSOD1 and TcSOD2 were down-regulated, in the fenpropathrin-treated group with 0.794- and 0.201-fold decreases, respectively. On the other hand, the expression of TcSOD3 was significantly increased (P<0.05), being 2.774-fold higher than in the control group. The expression of TcSOD2 was significantly down-regulated both the propargite- and cyflumetofen-treated groups (0.655- and 0.397-fold, respectively) (P<0.05). The data reported here indicate that SODs from T. cinnabarinus may play different and vital roles in anticipating the effects of oxidative damage at extreme temperatures and under different acaricides stress.

Objective: Many Fix Dose Combinations (FDCs) being introduced in India are usually irrational. The most pressing concern with irrational FDCs is that they expose patients to unnecessary risk of adverse drug reactions, for instance, pediatric formulations of nimesulide+paracetamol. Despite their wide clinical use, their gastro-intestinal toxicity is a major limitation. The aim of the present work was to evaluate the efficacy and safety of FDCs in non-steroidal anti-inflammatory drugs in the orthopedic department at a tertiary care teaching hospital. To study the effectiveness and safety parameters of fixed-dose combinations of Non-Steroidal Anti-inflammatory Drugs. Methods: This prospective, observational study was conducted among 150 out-patients of the orthopedic ward over a period of July 2013 to December 2013(Each combination with 50 patients). Three fixed-dose combinations utilized were paracetamol+diclofenac, paracetamol+ibuprofen and paracetamol+nimesulide. The effectiveness was analyzed by using Visual Analogue Scale (VAS) and Disease Activity Scale (DAS) and the safety criteria were analyzed by using the WHO probability scale and Naranjo scale. 150 orthopedic patients attending Out Patient Department were included. 50 participants for each of the combinations of fixed-dose combination (FDCs) of NSAIDs. Results: Out of 150 patients 33 patients developed adverse effects, and 17(51.51%) adverse effects due to the combination of Paracetmol+Nimuselide, 11(33.34%) adverse effects due to the Paracetamol+Ibuprofen and 5 (15.15%) were due to the combination of Paracetamol+Diclofenac. The maximum effectiveness (3.55±0.208) showed in the combination of paracetamol+diclofenac compared to the other two combinations. Conclusion: It was concluded from this study that the effectiveness and safety profile of PCM+DICLO is better than the other two FDCs.

Abstract In spite of advances in root canal therapy and better knowledge of pulpal and periapical inflammation, up 40% of endodontic patients report varying degrees of pain. The aim of this present study was to compare the effect of single preoperative dose of ibuprofen or dexamethasone on post-endodontic pain. Sixty volunteers were divided into three groups (n=20 per group): PL, placebo; IB, 400 mg of ibuprofen; and DE, 8 mg of dexamethasone. The primary outcome was the post-endodontic pain intensity measured with a numerical rating scale (4, 8, 12, 24, and 48 h). Secondary outcomes included number of anesthetic cartridges used and consumption of rescue medication. Data were analyzed by one-way ANOVA, chi-square and Kruskal-Wallis tests. There was no significant difference among groups (p>0.05) considering the pain intensity. Only 37% of IB group patients and 28% of DE group patients used some rescue medication. On the other hand, 74% of PL group patients mentioned the consumption of rescue medication; PL group had a statistically significant difference (p<0.05) in comparison with IB and DE groups. The number of anesthetic cartridges used had no statistically significant difference among the groups (p>0.05). Significant differences were not found in the reduction of pain intensity and the number of anesthetic cartridges used. Considering the consumption of rescue medication (secondary outcome), preoperative administration of Ibuprofen or dexamethasone reduces post-endodontic pain and discomfort in comparison with a placebo. Premedication with anti-inflammatory drugs drugs could be contributed to control of the post-endodontic pain, mainly in patients more sensible for pain.

Oral proteolytic enzymes like serratiopeptidase are very commonly used by clinicians either alone or in combination with non-steroidal anti-inflammatory drugs for analgesia and anti-inflammatory purpose. As the activity of these drugs is not proved in trials, and they are not listed in any country's official pharmacopoeia, it was planned to study their effect in osteoarthritis patients. Two groups (n= 30 each) of diagnosed knee osteoarthritis patients, were treated with diclofenac 50 mg twice a day (BID) and serratiopeptidase 10mg three times a day (TID) + Diclofenac 50 mg BID for two weeks. The pain and difficulty in daily activities were assessed by Visual Analogue Scale (VAS) and Western Ontario and Mc Masters Universities Osteoarthritis (WOMAC OA) index scale before and after the treatment.  Highly significant improvement in both scales was seen in both groups. There was no statistically significant difference in the improvements found in both groups.  Addition of serratiopeptidase has not potentiated analgesic and anti-inflammatory effects of diclofenac. Thus, the analgesic and anti-inflammatory efficacy of serratiopeptidase are not proved.

Background/Aim. Helicobacter pylori (H. pylori) infection and nonsteroidal anti-inflammatory drugs (NSAIDs) use are considered to be the most important risk factors having influence on the onset of bleeding gastroduodenal lesions. Whether there is an interaction between H. pylori infection and the use of NSAIDs in the development of peptic ulcer disease is still controversial. The aim of the present study was to evaluate the prevalence of NSAIDs use and H. pylori infection in patients presented with bleeding gastroduodenal lesions. Methods. During the period from January 2003 - December 2003 we prospectively obtained data of all the patients (n=106) presented with signs of upper gastrointestinal bleeding. All the patients were admitted to the intensive care unit, with the endoscopy performed within 12 hours after admission. Histologic analysis was used for the detection of H. pylori infection. The NSAIDs and aspirin use data were obtained by anamnesis. Results. The results of our study revealed that the most common sources of upper gastrointestinal bleeding were duodenal (57 patients, 53.77%) and ventricular (36 patients, 33.96%) ulcers. The majority of the examined cases were associated with both H. pylori infection and NSAIDs use. A statistically significant difference among the studied groups of patients was proven. Conclusion. The majority of bleeding gastroduodenal lesions were associated with the coexistence of H. pylori infection and NSAIDs use, while their independent influences were statistically less important. Eradication of H. pylori infection in patients using NSAIDs might prevent upper gastrointestinal hemorrhage and reduce peptic ulcer bleeding risk. .
