Efficacy of intravenous paracetamol and dexketoprofen on postoperative pain and morphine consumption after a lumbar disk surgery.

Background: We compared the analgesic effects of intravenous (IV) paracetamol with that of dexketoprofen on postoperative pain and morphine consumption during the first 24 hour after a lumbar disk surgery. Methods: This prospective, placebo-controlled, double blind study investigated the analgesic effects of IV paracetamol and dexketoprofen on postoperative pain, morphine consumption, and morphine-related side effects after a lumbar disk surgery. Sixty American Society of Anesthesiologists 1 or 2 status patients scheduled for elective lumbar disk surgery under general anesthesia were included in the study. Patients were treated using patient-controlled analgesia with morphine for 24 hours after a lumbar disk surgery and randomized to receive IV paracetamol 1 g, dexketoprofen 50 mg, or isotonic saline (placebo). The primary endpoint was pain intensity measured by the visual analogue scale, and secondary endpoints were morphine consumption and related side effects. Results: Pain intensity was lower in the dexketoprofen group (P=0.01) but not in the paracetamol group (P=0.21) when compared with the control group. Cumulative morphine consumption and morphine-related side effects did not reveal significant differences between the groups. Conclusions: The study showed that pain intensity during 24 hours after the lumbar disk surgery was significantly lowered by dexketoprofen, but not with paracetamol, as a supplemental analgesic to morphine patient-controlled analgesia when compared with controls.

Evaluation of body composition parameters in patients with psoriasis

Body composition parameters, such as weight, body mass index (BMI), and visceral fat rating, have been found to be associated with psoriasis. However, the associations of these parameters with psoriasis have not been demonstrated clearly.

Parental adjustment, parenting attitudes and emotional and behavioral problems in children with selective mutism.

The present study investigated emotional and behavioral problems in children with selective mutism (SM) along with the psychological adjustment and parenting attitudes of their mothers and fathers. Participants included 26 children with SM (mean age = 8.11 ± 2.11 years), 32 healthy controls (mean age = 8.18 ± 2.55 years) and the parents of all children. Children with SM displayed higher problem scores than controls in a variety of emotional and behavioral parameters. They predominantly displayed internalizing problems, whereas aggressive and delinquent behavior was described among a subsample of the children. Significant differences existed between the SM and control groups only in paternal psychopathology, which included anxiety and depression. They did not differ with respect to maternal psychological distress or mother or father reported parental attitudes. Another important result of the present study was that the severity of emotional and behavioral problems of children with SM was correlated with maternal psychopathology but not paternal psychopathology.

Evaluation of Advanced Oxidation Protein Products, Prooxidant-Antioxidant Balance, and Total Antioxidant Capacity in Untreated Vitiligo Patients

Background Vitiligo is a chronic, common disease of unknown etiology, and oxidative stress is suggested to have a role in its etiopathogenesis. Objective Advanced oxidation protein products (AOPPs), prooxidant-antioxidant balance (PAB), and ferric-reducing antioxidant power (FRAP) were evaluated regarding their role in the pathogenesis of vitiligo as well as their relationship with clinical presentation and disease severity, and these parameters were compared with those of healthy controls. Methods The study included 53 patients with vitiligo and 20 healthy volunteers as the control group. AOPP level, PAB, and FRAP were determined by colorimetric methods. Results PAB and FRAP level were significantly higher in patients with vitiligo than in healthy controls (p<0.001). The AOPP levels in vitiligo patients were not statistically significantly higher than those in healthy controls. The Vitiligo Area Scoring Index positively correlated with disease duration (rs: 0.531, p<0.001). Conclusion To the best of our knowledge, this is the first report of AOPP and PAB status in vitiligo. PAB may be used as an indicator for oxidative stress in the etiopathogenesis of vitiligo. Our results show that these parameters may play a major role in the melanocyte damage observed in vitiligo. Further studies are required to confirm the mechanisms underlying this effect.

Which one is more effective for analgesia in infratentorial craniotomy? The scalp block or local anesthetic infiltration

OBJECTIVES The most painful stages of craniotomy are the placement of the pin head holder and the skin incision. The primary aim of the present study is to compare the effects of the scalp block and the local anesthetic infiltration with bupivacaine 0.5% on the hemodynamic response during the pin head holder application and the skin incision in infratentorial craniotomies. The secondary aims are the effects on pain scores and morphine consumption during the postoperative 24h. METHODS This prospective, randomized and placebo controlled study included forty seven patients (ASA I, II and III). The scalp block was performed in the Group S, the local anesthetic infiltration was performed in the Group I and the control group (Group C) only received remifentanil as an analgesic during the intraoperative period. The hemodynamic response to the pin head holder application and the skin incision, as well as postoperative pain intensity, cumulative morphine consumption and opioid related side effects were compared. RESULTS The scalp block reduced the hemodynamic response to the pin head holder application and the skin incision in infratentorial craniotomies. The local anesthetic infiltration reduced the hemodynamic response to the skin incision. As well as both scalp block and local anesthetic infiltration reduced the cumulative morphine consumption in postoperative 24h. Moreover, the pain intensity was lower after scalp block in the early postoperative period. CONCLUSION The scalp block may provide better analgesia in infratentorial craniotomies than local anesthetic infiltration.

Efficacy of continuous positive airway pressure and incentive spirometry on respiratory functions during the postoperative period following supratentorial craniotomy: A prospective randomized controlled study

STUDY OBJECTIVE Volume controlled ventilation with low PEEP is used in neuro-anesthesia to provide constant PaCO2 levels and prevent raised intracranial pressure. Therefore, neurosurgery patients prone to atelectasis formation, however, we could not find any study that evaluates prevention of postoperative pulmonary complications in neurosurgery. DESIGN A prospective, randomized controlled study. SETTING Intensive care unit in a university hospital in Istanbul. PATIENTS Seventy-nine ASAI-II patients aged between 18 and 70years scheduled for elective supratentorial craniotomy were included in the study. INTERVENTIONS Patients randomized into 3 groups after surgery. The Group IS (n=20) was treated with incentive spirometry 5 times in 1min and 5min per hour, the Group CPAP (n=20) with continuous positive airway pressure 10 cmH2O pressure and 0.4 FiO2 via an oronasal mask 5min per hour, and the Group Control (n=20) 4L·min-1O2 via mask; all during the first 6h postoperatively. Respiratory functions tests and arterial blood gases analysis were performed before the induction of anesthesia (Baseline), 30min, 6h, 24h postoperatively. MAIN RESULTS The IS and CPAP applications have similar effects with respect to FVC values. The postoperative 30min FEV1 values were statistically significantly reduced compared to the Baseline in all groups (p<0.0001). FEV1 values were statistically significantly increased at the postoperative 24h compared to the postoperative 30min in the Groups IS and CPAP (p<0.0001). This increase, however, was not observed in the Group Control, and the postoperative 24h FEV1 values were statistically significantly lower in the Group Control compared to the Group IS (p=0.015). CONCLUSION Although this study is underpowered to detect differences in FEV1 values, the postoperative 24h FEV1 values were significantly higher in the IS group than the Control group and this difference was not observed between the CPAP and Control groups. It might be evaluate a favorable effect of IS in neurosurgery patients. But larger studies are needed to make a certain conclusion.

The role of “Integrated Pulmonary Index” monitoring during morphine-based intravenous patient-controlled analgesia administration following supratentorial craniotomies: a prospective, randomized, double-blind controlled study

Abstract Objective: Morphine is commonly used in post-operative analgesia, but opioid-related respiratory depression causes a general reluctance for its use. The “Integrated Pulmonary Index” is a tool calculated from non-invasively obtained respiratory and hemodynamic parameters. The aim of this prospective, randomized, double blind, and placebo-controlled study is to determine a more safe and effective dose for morphine in patient-controlled analgesia following supratentorial craniotomy using the “Integrated Pulmonary Index”. Methods: This study included 60 patients (ASA I, II, and III). All patients used iv PCA for 24 h following supratentorial craniotomy. The PCA was set to administer a bolus dose of 1 mg morphine in Group 1 and 0.5 mg morphine in Group 2. The PCA contained placebo in Group 3 and patients received dexketoprofen 50 mg iv after awakening, repeated every 8 h. The IPI and NRS scores, total morphine consumption, and morphine related side-effects were recorded at 10 min, 1, 2, 6, 12, and 24 h post-operatively. The lowest IPI score, count of apnea, and desaturation events were recorded during the study period. Results: The IPI scores were similar among the groups. Although a statistically significant difference was not observed among the groups the lowest IPI scores were observed in Group 1; apnea and desaturation counts were also higher in Group 1. Statistically significant differences were not observed among the groups in terms of pain scores, but were lower in Groups 1 and 2 compared to Group 3. Conclusion: Patient controlled analgesia with 0.5 mg morphine may be safe and effective for pain management following supratentorial craniotomies. Integrated pulmonary index can be used for detecting opioid-induced respiratory depression. Clinical Trials registration number: NCT02929147.
