Introduction: Carbon monoxide (CO) poisoning is a crucial cause of delayed neuropsychiatric syndrome (DNS). However, most biomarkers are not satisfactory for the prediction of DNS caused by CO poisoning. Thus, we evaluated the adequacy of the serum glucose/potassium (GLU/K) ratio, which may be an easy, quick, and readily available parameter that can be used in the emergency department for predicting DNS. Methods: We evaluated 281 patients who were admitted to our emergency department between January 2012 and December 2018. The patients were divided into two groups: DNS (+) and DNS (−). The GLU/K was compared for the groups. Results: Glucose, blood urea nitrogen, carboxyhemoglobin, and GLU/K ratios of patients in the DNS (+) group were statistically significantly higher than those patients in DNS (−) group (140 ± 34 vs. 110 ± 24, p < 0.001; 17.58 ± 6.14 vs. 14.27 ± 5.08, p = 0.003; 29 ± 5.1 vs. 18.9 ± 7.6, p < 0.001; and 38.35 ± 10.11 vs. 28.65 ± 6.53, p < 0.001, respectively). The area under the curve for GLU/K to predict DNS was measured as 0.791, and 35.9 as a cut-off value had 63.6% sensitivity and 89.6% specificity. Conclusions: DNS development in CO poisoning is a serious and feared complication. We suggest that the GLU/K ratio has a high potential as a rapid, easy preliminary marker for the exclusion of patients who will not subsequently develop DNS.

Objectives/Hypothesis: The aims of this study were to evaluate the diagnostic test features of bedside ultrasonography in pediatric patients with nasal trauma and to investigate whether it is a preferable alternative method to conventional radiography (CR).Study Design: Cross-sectional prospective study.Methods: This prospective study was conducted from March 1, 2019, through November 1, 2019. Thirty-one patients under the age of 18 years who had nasal trauma were consecutively included. CR and ultrasonographic imaging tests were investigated in patients with clinical indications for nasal bone fracture. The sensitivity, specificity, and accuracy of ultrasonography and CR were calculated with respect to detecting nasal fractures according to the gold standard method.Results: Participants were between 3 and 16 years old and the median age was 8 (5-13) years. Nasal bone fracture was clinically detected in 18 patients. While 13 of these fractures were detected with ultrasonography, only 11 were also detected with CR. The sensitivity and specificity of ultrasonography and CR in detecting nasal fractures were 72.2% (95% confidence interval [CI]: 46.5-90.3) and 76.9% (95% CI: 46.2-95.0) for ultrasonography and 61.1% (95% CI: 35.8-82.7) and 69.2% (95% CI: 38.6-90.9) for CR.Conclusions: According to the results of this study, ultrasonography may be used with confidence as a first imaging method in the investigation of nasal fractures, particularly with consideration for avoiding the effects of radiation as much as possible. Our findings point to the next step of conducting trials with a greater number of patients in order to define the diagnostic test features of ultrasonography in pediatric patients.

Aim Ovarian torsion is a gynecopathology that requires emergency surgery in women. However, ischemia reperfusion injury (IRI) occurs after treatment with detorsion. This study aimed to evaluate the effects of monoacylglycerol lipase inhibitor JZL184 on ovarian IRI and ovarian reserve. Methods Forty‐eight female Wistar albino rats were divided into six groups. Group 1: Sham, Group 2: Ischemia, Group 3: ischemia/reperfusion (IR), Group 4: IR + JZL184 4 mg/kg, Group 5: IR + JZL184 16 mg/kg, Group 6: IR + vehicle (dimethyl sulfoxide). Three hours of ischemia followed by 3 h of reperfusion. Two different doses of JZL184 (4 and 16 mg/kg) were administered intraperitoneally in Group 4 and 5, 30 min before reperfusion. Ovarian IRI and ovarian reserve were evaluated in serum and tissue by using histopathological and biochemical parameters. Results Treatment with JZL184 was associated with a significant increase in ovarian 2‐arachidonoylglycerol and improved serum anti‐Mullerian hormone, İnhibin B, primordial follicle count, and ovarian histopathological damage score (p < 0.05). JZL184 treatment significantly decreased the level of malondialdehyde, and increased superoxide dismutase enzyme activity and glutathione (GSH) levels (p < 0.05). The increased phosphorile nuclear factor‐κB (Phospho‐NF‐κB‐p65), tumor necrosis factor alpha (TNF‐α), interleukin‐1beta (IL‐1β), transforming growth factor beta 1 (TGF‐β1), and TUNEL assay immunopositivity scores in ovarian I/R injury were decreased after treatment with JZL184 (p < 0.05). Conclusions JZL184 showed significant ameliorative effects on ovarian IRI and ovarian reserve caused by IR through acting as an antioxidant, anti‐inflammatory, and antiapoptotic agent. Thus, JZL184 may be a novel therapeutic agent for ovarian IRI.
