Publication Metadata only An unusual complication following unconventional use of high pressure injector(SAGE PUBLICATIONS LTD, 2013) DENİZBAŞI ALTINOK, ARZU; Eroglu, S. E.; Tezel, S.; Salcin, E.; Denizbasi, A.; Onur, O.; Ozpolat, C.; Demir, H.High pressure injection injuries most commonly occur in industrial accidents. In accident due to high pressure gun injuries, the nature of injected materials, the degree of toxicity, and the amount injected will affect the clinical outcome. Early vigorous treatment is essential to reduce morbidity. We reported a case of hand injuries due to inadvertent use of a high pressure injector device for haemostasis. 46-year-old male technician tried to stop bleeding from his injured hand by directing air jet from a high pressure injector to the wound resulting in significant subcutaneous emphysema. Adequate training and knowledge on occupational safety should be reinforced to avoid similar accidents.Publication Metadata only Diagnostic utility of the Covichem score in predicting COVID-19 disease(2022-10-01) ÖZPOLAT, ÇİĞDEM; ALTUNBAŞ, ERHAN; ÖZPOLAT Ç., Altunbas E.© 2022 Elsevier Inc.Background: Identifying which patients with COVİD-19 have a high risk of severe illness is essential to optimizing management and resource utilization strategies. Objectives: The aim of this study was to externally validate the diagnostic utility of the Covichem score for predicting COVID-19 disease severity, and secondarily to evaluate its utility in predicting intensive care unit (ICU) admission, and in-hospital mortality. Methods: All consecutive COVID-19 patients who presented to the emergency department (ED) were included, and patients\" demographic data, comorbidities, vital signs, oxygen requirement, and laboratory results were recorded. We calculated patients\" Covichem scores and estimates (using a threshold of 0.5) and evaluated the utility of the Covichem score for predicting disease severity, ICU admission, and mortality. Results: The median Covichem score was significantly higher for patients with severe illness (Covichem score: 0.170, IQR: 0.298, n = 300 vs. Covichem score: 0.026, IQR: 0.065, n: 191; p < 0.001). Based on their Covichem scores, 12.4% (61/491) of the patients were predicted to experience severe illness (threshold: 0.5), the accuracy of the Covichem score was poor, as the area under curve (AUC) was 48.5% (18.1% sensitivity and 93.8% specificity). When we calculated a new ideal threshold, the AUC reached 82%, but the sensitivity was 79.9% and the specificity was 71.2%. Conclusion: In this external validation of the Covichem score, we found that it performed worse than in the original derivation and validation study, even with the assistance of a new cutoff.Publication Metadata only INITIAL AND SUSTAINED RESPONSE EFFECTS OF 3 VAGAL MANEUVERS IN SUPRAVENTRICULAR TACHYCARDIA: A RANDOMIZED, CLINICAL TRIAL(ELSEVIER SCIENCE INC, 2019) DENİZBAŞI ALTINOK, ARZU; Ceylan, Ezgi; Ozpolat, Cigdem; Onur, Ozge; Akoglu, Haldun; Denizbasi, ArzuBackground: For acute termination of supraventricular tachycardia (SVT), vagal maneuvers, including the standard Valsalva maneuver (sVM), modified Valsalva (mVM) maneuver, and carotid sinus massage (CSM), are first-line interventions. There is no criterion standard technique. Objective: This prospective, randomized study was aimed at analyzing the success rates of these 3 vagal maneuvers as measured by sustaining sinus rhythm at the fifth minute and SVT termination. Methods: We conducted this prospective, randomized controlled study in an emergency department (ED). We enrolled all the patients who were admitted to the ED and diagnosed with SVT. We randomly assigned them to 3 groups receiving sVM, mVM, and CSM and recorded the patients' responses to the vagal maneuvers and SVT recurrence after vagal maneuvers. Results: The study was completed with 98 patients. A total of 25 (25.5%) instances of SVT were initially treated successfully with vagal maneuvers. The success rate was 43.7% (14/32 cases) from mVM, 24.2% (8/33) for sVM, and 9.1 % (3/33) for CSM (p < 0.05). At the end of the fifth minute, only 12.2% (12/98) of all patients had sinus rhythm. Sinus rhythm persisted in 28.1% (9/32) of patients in the mVM group, 6.1% (2/33) of patients in the sVM group, and 3% (1/33) in the CSM group at the fifth minute (p < 0.05). Conclusion: mVM is superior to the CSM maneuver in terminating SVT and maintaining rhythm. We conclude that it is beneficial to use mVM, which is more effective and lacks side effects.

A multifunctional peptide adrenomedullin (AM) has protective effects in the central nervous system. We evaluated AM in an animal model as a therapeutic agent that reduces brain damage after traumatic brain injury. A total of 36 rats was divided into 3 groups as sham, head trauma plus intraperitoneal (ip) saline, and head trauma plus adrenomedullin ip. The diffuse brain injury model of Marmarou et al. was used. Blood samples were taken from all groups at the 1st, 6th and 24th hours for analysis of TNF-alpha (tumor necrosis factor-alpha), IL-1 beta (interleukin-1 beta) and IL-6 (interleukin-6) levels. At the end of the study (at the 24th hour) a neurological examination was performed and half of the rats were decapitated to obtain blood and tissue samples, the other half were perfused transcardiacally for studying the histopathology of the brain tissue. There were no statistically significant changes in plasma levels of IL-1 beta, IL-6 and TNF-alpha relative to the sham group. Also, changes in tissue levels of malonedialdehyde, myeloperoxidase and glutathione were not statistically significant. However, neurological scores and histopathological examinations revealed healing. AM individually exerts neuroprotective effects in animal models of acute brain injury. But the mechanisms of action remain to be assessed. (C) 2013 Elsevier Inc.

Predictive values of weight, body mass index (BMI) and CWT were also analyzed. Materials and Methods: This study included 199 measurements of 50 adult fresh cadavers from both hemithoraces. Five-centimeter-long syringe needles were inserted and secured. Penetration into the pleural cavity was assessed, and CWTs at 4 locations were measured. Achieved power of this study for the primary aim of CWT comparison from 2nd and 5th ICSs was .94. Results: Overall mean CWTs at 2nd ICS MCL and 5th ICS MAL were measured as 2.46 +/- 0.78 and 2.89 +/- 1.09, respectively, and 5th ICSMAL was found to be statistically thicker (P - .002). The success rate of NT at 2nd ICS MCL was 87% (95% CI, 80-94), and that at 5th ICSMAL was 78% (95% CI, 70-86; P = .3570). Only 6 (17.1%) of 35 failed NTs had a CWT greater than 5-cm. Needle thoracostomy has failed in 29 (14.9%) of 194 locations, despite a CWT less than 5-cm. Below a weight of 72 kg, BMI of 23 kg/m(2), or CWT of 2.4 cm, all NTs were successful. Discussion and Conclusions: In this report, we present the largest cadaver-based cohort to date to the best of our knowledge, and we observed a statistically nonsignificant 9% more NT success rate at 2nd ICS at a power of 88% and statistically significant more success rate in males at 5th ICS was (47.7%). We also observed thinner CWTs and higher success rates than previous imaging-based studies. A BMI of 23 kg/m(2) or less and weight of 72 kg or less seem to accurately rule-out NT failure in cadavers, and they seem to be better predictors at the bedside. (C) 2016 Elsevier Inc.
