    The area under the curve (AUC), sensitivity, and specificity of Tzanakis score in the cut-off value of 8 were 0.965, 84.4%, and 100%, respectively. For Ohmann and Alvarado scores, these measures were 0.941; 71.9%, 89.9% and 0.938, 60.9%, 89.9%, respectively. Tzanakis scoring system had the best screening performance in detection of cases with AA. Conclusion Tzanakis score is more sensitive and specific than Alvarado, RIPASA, Eskelinen and Ohmann scores in identifying AA patients needing appendectomy.Introduction There is an increasing interest in the use of different biomarkers to help distinguish psychogenic non-epileptic seizure (PNES) from epileptic seizures (ES). This study aimed to evaluate the patterns of differentially expressed serum proteins in ES and PNES cases. Methods In this cross-sectional study, 4 patients with mesial temporal lobe epilepsy and 4 patients with PNES were selected from patients with history of recurrent seizures. Venous blood samples were obtained within 1 hour after seizure and serum proteomes as well as the extent of protein expression were analyzed. Results 361 proteins were identified; of these, expression of 197 proteins had altered. 110 (55.9%) proteins were down-regulated and 87 (44.1%) were up-regulated in the PNES samples compared to ES samples. The mean pI for deregulated proteins with 1.5 to 3 fold changes were 6.69 ± 1.68 in proteins with increasing expression in ES group and 5.88 ± 1.39 in proteins with increasing expression in PNES group (p = 0.008). The median and interquartile range (IQR) of molecular weight changes in proteins with 1.5 to 3 fold changes were 64 (22.0-86.0) in proteins whose expression had increased in ES group and 39.5 (26.0-61.5) in proteins whose expression had increased in PNES cases (p = 0.05). Conclusion Several spots with differential expression were observed by comparing patients with ES against the PNES groups, which could be potential biomarkers of the disease. Damage to the blood-brain barrier is the most important difference between the two groups, thus identifying total protein changes offers a key to the future of differentiating ES and PNES patients.Introduction Studies have shown that naloxone can cause behavioral changes in naïve normal volunteers. This study aimed to investigate the possible complications of naloxone in methadone-overdosed opioid-naïve patients. Methods In this pilot study, a total number of 20 opioid-naïve methadone-poisoned patients underwent naloxone challenge test to receive naltrexone. 0.2, 0.6, and 1.2 mg doses of naloxone were administered on minutes 0, 5, and 15-20. The patients were followed for 30 minutes after administration of naloxone and monitored for any upsetting signs and symptoms. Patients with clinical opiate withdrawal scale (COWS) lower than 5 were considered not addicted and the severity of patients’ symptoms was calculated using subjective opiate withdrawal syndrome (SOWS). Results 20 patients with mean age of 25.5±8.09 years were evaluated (70% female). Median ingested dose of methadone was 25 mg and mean time interval between ingestion of methadone and naloxone challenge test was 7.1±4.9 hours. CH-223191 nmr Fourteen patients reported some discomfort after administration of a mean dose of 1.7±0.5 mg of naloxone lasting for a maximum of four hours. The most common patients’ complaints were headache (45%) followed by nausea (20%), agitation (20%), abdominal pain (20%), and flushing (20%). Two (10%) mentioned severe panic attack and sensation of near-coming death. SOWS significantly correlated with female gender (p = 0.004) and time elapsed post methadone ingestion (p = 0.001). Conclusion It seems that naloxone is not a completely safe medication even in opioid-naïve patients, and administrating adjusted doses of naloxone even in opioid-naïve methadone intoxicated patients may be logical.Introduction Few studies have described their experience using esmolol, an ultra-short acting β-adrenergic antagonist, in the emergency department (ED) as a feasible adjuvant therapy for the treatment of refractory ventricular fibrillation/pulseless ventricular tachycardia (VF/pVT) out-of-hospital cardiac arrest. However, there is currently insufficient evidence to support the widespread implementation of this therapy. The aim of this scoping review was to summarize the current available evidence on the use of esmolol as an adjuvant therapy for refractory VF/pVT out-of-hospital cardiac arrest, as well as to identify gaps within the literature that may require further research. Methods We conducted a comprehensive literature search of MEDLINE via PubMed, Embase, Scopus, and the Cochrane Central Register of Controlled Trials (CENTRAL) on July 5, 2019. The search was restricted to articles that were published from January 2000 to July 2019. Google Scholar was searched and reference lists of relevant papers were -of-hospital cardiac arrest based on the available evidence. The findings of this scoping review suggest that there is a paucity of research and limited evidence to support this therapy.Introduction Tramadol is an active analgesic drug that is commonly used to treat moderate to severe pain. The present study aimed to assess the arterial blood gas (ABG) analysis of patients with tramadol-induced seizure (TIS). Methods This prospective cross-sectional study was performed on 50 TIS cases that were referred to emergency department within a maximum of one hour after their last episode of seizure. The results of ABG analysis on admission were collected and their association with dosage and time interval between ingestion and admission was assessed. Results 50 cases with the mean age of 35.10 ± 9.62 years were studied (80.0% male). The mean dosage of ingestion was 1122.00 ± 613.88 (400 to 3000) mg and the mean time interval between ingestion and admission was 7.16 ± 2.18 hours. ABG analysis on admission showed that 49 (98.0%) patients had pH 45 mmHg (respiratory acidosis). There was a significant association between ingestion to admission time interval and both PaCO2 (r = -0.330, p = 0.019), and PaO2 (r = 0.303, p = 0.032). The dose of ingestion was negatively associated with respiratory rate (r = -0.556, p = 0.001), arterial pH (r = -0.676, p = 0.001), and PaO2 (r = -0.514, p = 0.001), but was positively associated with PaCO2 (r = 0.461, p = 0.001). Higher doses of tramadol led to more severe hypercapnia and need for intubation (OR = 1.12, 95% CI 0.88 – 1.26; p = 0.045). 5 (10.0%) cases needed mechanical ventilation. All patients improved after supportive care with no in-hospital death. Conclusion Based on the findings, 98% of TIS cases had respiratory acidosis. Higher doses of ingested drug and longer time interval between ingestion and admission were associated with severity of ABG disturbances.
