Abstract
BACKGROUND Anti-inflammatory drugs are commonly used to lower inflammation which is linked to a variety of disorders. It acts by inhibiting cyclooxygenase-mediated prostaglandin synthesis at the molecular level. Hematoma is related with the use of anti-inflammatory medications. However, the specific link is still unknown. Thus, the main objective of the study is to find out the association of hematoma with ant-inflammatory drugs. MATERIAL AND METHODS The relevant studies were searched in PubMed and screened based on inclusion and exclusion criteria. The quality of full-text studies was assessed using suitable Newcastle-Ottawa Scale. The overall estimate was calculated in terms of odds ratio with 95% confidence interval. The random effect model was used. The qualitative analysis of publication bias was done through funnel plot. RESULTS The overall estimate measures [OR 1.01 (0.50, 2.06)] have shown non-significant risk of hematoma with use of anti-inflammatory drugs in plastic surgery as compared to non-anti-inflammatory drugs. The heterogeneity among studies was found to be 34%. The subgroup analysis of individual drugs was not done due to availability of a smaller number of studies. CONCLUSION Based on available data, there is no significant risk of hematoma with use of anti-inflammatory drugs in plastic surgery.

Abstract
INTRODUCTION Opioids prescribed after surgery accounted for 5% of the 191 million opioid prescriptions filled in 2017. Approximately 80% of the opioid pills prescribed by surgical care providers remain unused, leaving a substantial number of opioids available for non-medical use. We developed a multi-component intervention to address surgical providers' role in the overprescribing of opioids. Our study will determine effective strategies for reducing post-surgical prescribing while ensuring adequate post-surgery patient-reported pain-related outcomes, and will assess implementation of the strategies. METHODS AND ANALYSIS The Minimising Opioid Prescribing in Surgery study will implement a multi-component intervention, in an Illinois network of six hospitals (one academical, two large community and three small community hospitals), to decrease opioid analgesics prescribed after surgery. The multi-component intervention involves four domains: (1) patient expectation setting, (2) baseline assessment of opioid use, (3) perioperative pain control optimisation and (4) post-surgical opioid minimisation. Four surgical specialities (general, orthopaedics, urology and gynaecology) at the six hospitals will implement the intervention. A mixed-methods approach will be used to assess the implementation and effectiveness of the intervention. Data from the network's enterprise data warehouse will be used to evaluate the intervention's effect on post-surgical prescriptions and a survey will collect pain-related patient-reported outcomes. Intervention effectiveness will be determined using a triangulation design, mixed-methods approach with staggered speciality-specific implementation for contemporaneous control of opioid prescribing changes over time. The Consolidated Framework for Implementation Research will be used to evaluate the site-specific contextual factors and adaptations to achieve implementation at each site. ETHICS AND DISSEMINATION The study aims to identify the most effective hospital-type and speciality-specific intervention bundles for rapid dissemination into our 56-hospital learning collaborative and in hospitals throughout the USA. All study activities have been approved by the Northwestern University Institutional Review Board (ID STU00205053).

A Randomized Double-Blind Active Comparator Pilot Study. Front Surg 2018; 5:59.

Abstract
Introduction: Acute postoperative pain following knee arthroscopy is common in orthopedic surgeries. Managing pain postoperatively combines usage of opioids and non-steroidal anti-inflammatory drugs. The aim of this clinical study was to assess the efficacy of two different analgesic treatment regimens: intravenous (IV) ibuprofen and IV ketorolac for the treatment of postoperative pain pertaining to arthroscopic knee surgery. Methods: This was a single center, randomized, double-blind, parallel, active comparator clinical pilot study. Subjects were randomized to receive either IV ibuprofen, administered as two 800 mg doses or IV ketorolac, administered as a single 30 mg dose. Subjects in the ibuprofen group received 800 mg of IV ibuprofen within 2 h prior to surgery and a repeated second dose 4 h after the initial dose if they had not been discharged. Subjects in the ketorolac group received IV ketorolac 30 mg at the end of surgery, as per the manufacturer's recommendations. Pain assessments and opioid consumption data were collected up to 24 h postoperatively. Results: Of 53 randomized subjects, 51 completed the study. There were 20 subjects in the ibuprofen group and 31 subjects in the ketorolac group. The median (IQR) visual analog scale (VAS) pain score at resting upon post-anesthesia care unit (PACU) arrival was 33 (12, 52) vs. 9 (2, 25) (p = 0.0064) for the ketorolac and ibuprofen group, respectively. The median (IQR) visual analog scale (VAS) pain score at movement upon PACU arrival was 38 (20, 61) vs. 15 (6, 31) (p = 0.0018) for the ketorolac and ibuprofen group, respectively. Median VAS pain scores during movement taken at subsequent 30 min intervals in the ibuprofen group were less than half that of those reported in the ketorolac group for up to 90 min after arriving in PACU. The median VAS pain scores at rest and movement in the course of 120 min-24 h after PACU arrival was not statistically significant in both groups. Rescue opioid medication during PACU stay was required in 55.0% (N = 11) and 83.9% (N = 26), with a mean amount of narcotic consumption (oral morphine conversion) of 5.53 ± 5.89 mg vs. 19.92 ± 15.63 mg for the ibuprofen and ketorolac group, respectively (P < 0.001). However, opioid consumption during the first 24 h after PACU discharge was not statistically significant (p-value = 0.637). The mean time to first rescue medication was 77.62 ± 33.03 and 55.78 ± 35.37 for the ibuprofen and ketorolac group, respectively (p-value = 0.0456). There were no significant differences in patient satisfaction and documented adverse events during the first 24 h. Conclusion: This pilot study showed that the use of preemptive IV ibuprofen 800 mg could be considered to reduce postoperative pain and opioid consumption. Future prospective clinical trials using similar regimens should be conducted in order to gain a better understanding of how to best provide perioperative analgesic regimens.

Abstract
Background Considering the effect of statins on the regulation of dopamine neurotransmitters and glutamates and importance of the treatment of obsessive-compulsive disorder (OCD) due to its relatively high prevalence and disability of available drugs in treatment of many patients, we came to the point to examine effectiveness of statins in patients with OCD. Materials and Methods This study is a double-blind randomized clinical trial, which is done in OCD clinic of Isfahan Shariati in 2014 for 1 year. The target population consists of 64 patients with OCD; one group is given a daily 40 mg atorvastatin tablets and the other group receives placebo. At baseline, 4- and 8-week severities of obsessive-compulsive symptoms are measured using Yale-Brown scale and compared in the two groups. Results The study results show a statistically significant difference between the two groups of intervention and control (P < 0.001). Furthermore, the results show the intervention effect at the end of the 4th week and 8th week (P < 0.001) that this change is evident in the 4th week but remained almost constant in the 8th week. Conclusion Overall, the evidences obtained from the study declare the effects of adding statins to treat obsessive-compulsive symptoms.

Abstract
We present the case of a 63-year-old man, admitted for hand cellulitis and acute kidney injury. A Streptococcus dysgalactiae subsp equisimilis (SDSE) was isolated in blood cultures and despite directed intravenous antibiotherapy, the patient evolved unfavourably, with dorsolumbar spondylodiscitis, multifocal septic arthritis and abscesses. CT also showed densification of the gluteal muscles, multiple air bubbles in the psoas, paraspinal muscles and spinal canal that were associated with an intramuscular injection administered 1 week earlier for a backache. After escalation of the antibiotherapy and intensive supportive measures, the patient showed improvement and was discharged after 8 weeks of antibiotherapy.The incidence of invasive SDSE infections has been growing, especially in immunosupressed patients. In this case, despite no predisposing factor identified, it evolved to severe sepsis. The intramuscular injection, a trivialised but not harmless procedure, was the assumed port of entry, as previously described in another case report.

Abstract
BACKGROUND Nonsteroidal antiinflammatory drugs such as ibuprofen are common medications with multiple useful effects, including pain relief and reduction of inflammation. However, surgeons commonly withhold all nonsteroidal antiinflammatory drugs perioperatively because of bleeding concerns. However, not all nonsteroidal antiinflammatory drugs irreversibly block platelet function. The authors hypothesized that the use of ibuprofen would have no effect on postoperative bleeding in plastic surgery patients. METHODS A literature review was performed using MEDLINE (PubMed), EMBASE, and the Cochrane Collaboration Library for primary research articles on ibuprofen and bleeding. Inclusion criteria were primary journal articles examining treatment of acute postoperative pain based on any modality. Data related to pain assessment, postoperative recovery, and complications were extracted. Bias assessment and meta-analysis were performed. RESULTS A total of 881 publications were reviewed. Four primary randomized controlled trials were selected for full analysis. Articles were of high quality by bias assessment. No significant difference was noted regarding bleeding events (p = 0.32), and pain control was noted to be equivalent. CONCLUSIONS Ibuprofen is a useful medication in the setting of surgery, with multiple beneficial effects. This meta-analysis represents a small set of high-quality studies suggesting that ibuprofen provides pain control equivalent to narcotics. Importantly, ibuprofen was not associated with an increased risk of bleeding. Further large studies will be necessary to elucidate this issue further, but ibuprofen is a safe postoperative analgesic in patients undergoing common plastic surgery soft-tissue procedures.

Abstract
PURPOSE The difficulties related to treatment of deep surgical site infection involve formation of biofilm on the surface of synthetic material. It is considered that in treatment of infections involving formation of biofilm, concomitant therapy shall be applied covering anti-inflammatory drugs. The purpose of the work was to assess the impact of diclofenac and ibuprofen on bacterial biofilm formation on the surface of monofilament polypropylene mesh. MATERIALS AND METHODS The study involved 70 strains of Staphylococcus aureus and 70 strains of Escherichia coli isolated from different patients and those which differ with chromosomal DNA pattern within the species. The assessment of the impact of non-steroidal anti-inflammatory drugs (NSAIDs) on biofilm formation was carried out with the use of qualitative method (TTC reduction), quantitative (tenfold serial dilution) and with the use of scanning electron microscope (SEM). RESULTS In the qualitative assessment, after incubation in the medium containing NSAIDs statistically significant growth of S. aureus strain amount and E. coli which poorly make up biofilm was stated. Quantitative examination indicated characteristic decrease of the number of colony forming units in 1 ml of the suspension isolated from bacterial biofilm formed as a result of incubation of isolates in the medium with the addition of examined NSAIDs in comparison to biofilm from control regimen. In the examination with the use of SEM it was stated that the effect of isolates incubation in the medium with NSAIDs was decrease of the number of bacteria adjacent to the biomaterial surface. CONCLUSIONS Diclofenac and ibuprofen in the concentration obtained in the serum limit the formation of biofilm by S. aureus and E. coli.

Abstract
A comprehensive understanding of operative anesthesia and postoperative pain control is essential to the practicing colon and rectal surgeon. Most of the operations performed-particularly in the perineum-cause significant patient discomfort and often result in a lengthy recovery period. A variety of factors, including patient positioning in the operating room and patient expectations, influence the choice of operative anesthesia. Postoperatively numerous modalities and agents exist for pain control. With this variety of options at hand, surgeons should be educated and decisions should be individualized, with the ultimate goals of improving the patient experience and facilitating recovery.

Abstract
BACKGROUND AND PURPOSE To decrease postoperative dependence on narcotics for analgesia, we have evaluated ketorolac as an adjunct to perioperative pain control in patients undergoing laparoscopic urologic surgery. PATIENTS AND METHODS Sixty-five patients (34 male, 31 female) were randomized to receive either ketorolac tromethamine (15-30 mg IV q 6 h) or placebo prior to laparoscopic surgery. Patient-controlled analgesia in the form of morphine sulfate was provided. Operative factors such as the type of surgery, operative time, and estimated blood loss were recorded. Postoperative factors such as analog pain score (range 0-10), narcotic usage, and length of stay were evaluated. RESULTS Fifty-five patients completed the study. The average pain score was 2.2 and 4.5 for the ketorolac and placebo groups, respectively (P < 0.005). The mean amounts of total morphine used were 39.2 mg (ketorolac) and 62.5 mg (placebo) (P = 0.077). The length of stay was not significantly different in the ketorolac (2.5 days) and placebo (2.6 days) groups (P = 0.74). Operative times (P = 0.21) and estimated blood loss (P = 0.60) were not significantly different in the two groups. Ketorolac did not adversely affect renal function; serum creatinine changes were not significantly different from those in the patients receiving placebo (P = 0.50). Laparoscopic pyeloplasty necessitated more narcotic analgesia than did other laparoscopic procedures (P = 0.05). CONCLUSION Ketorolac decreases the subjective perception of pain after laparoscopic urologic surgery. It is suggested that ketorolac administration decreases the amount of narcotic usage as well. Time to resumption of oral intake and length of hospital stay were not influenced by use of ketorolac.

Abstract
Pain management has become an increasingly well researched area in medicine over recent years, and there have been advances in a number of areas. While opioids remain an integral part of pain-management strategies, there is now an emphasis on the use of adjuvant drugs, such as paracetamol and anti-inflammatory agents, which through physiological or pharmacological synergism, both enhance pain control and reduce opioid use. The management of neuropathic pain continues to be a challenge. Anti-epileptics and antidepressants, together with clonidine and ketamine, provide the foundations for treatment. Another area of interest has been the widespread use of patient-controlled analgesia and the administration of some drugs, especially opioids, by means other than traditional oral and parenteral routes. The number of new drugs that have reached the stage of clinical trials has been small, yet they offer exciting possibilities. The epibatidine analogue ABT-594 and zinconitide both offer novel approaches to the management of neuropathic pain states, while selective cyclo-oxygenase-2 inhibitors and nitroaspirins may see advances in the management of nociceptive pain states.
