Item Determination of Risk Factors for Postoperative Acute Kidney Injury in Patients With Gynecologic Malignancies(2023) Doganci, Melek; Zeyneloglu, Pinar; Kayhan, Zeynep; Ayhan, Ali; 37575800; IVV-1127-2023; C-3736-2018; AAJ-4623-2021BackgroundPostoperative acute kidney injury (AKI) is an important cause of mortality and morbidity among surgical patients. There is little information on the occurrence of AKI after operations for gynecologic malignancies. This study aimed to determine the incidence of AKI in patients who underwent surgery for gynecological malignancies and determine the risk factors in those who developed postoperative AKI. MethodologyA total of 1,000 patients were enrolled retrospectively from January 2007 to March 2013. AKI was defined according to the Kidney Disease Improving Global Outcomes 2012 Clinical Practice Guideline for Acute Kidney Injury. Perioperative variables of patients were collected from medical charts.ResultsThe incidence of postoperative AKI was 8.8%, with stage 1 occurring in 5.9%, stage 2 in 2.4%, and stage 3 in 0.5% of the patients. Patients who had AKI were significantly older, had higher body mass index (BMI) higher preoperative C-reactive protein (CRP) levels, and more frequently had a history of distant organ metastasis when compared with those who did not have AKI. When compared with patients who did not develop AKI postoperatively, longer operation times and intraoperative usage of higher amounts of erythrocyte suspension and fresh frozen plasma were seen in those who developed AKI. ConclusionsPatients who had AKI were older, had higher BMI with higher preoperative CRP levels, more frequent distant organ metastasis, longer operation times, and higher amounts of blood transfused intraoperatively. Defining preoperative, intraoperative, and postoperative risk factors for postoperative AKI and taking necessary precautions are important for the early detection and intervention of AKI.Item Case Reports: Should We Do Away with Them?(2017) Firat, Aynur Camkiran; Araz, Coskun; Kayhan, Zeynep; 0000-0002-4927-6660; 0000-0003-0579-1115; 0000-0003-1470-7501; 28235534; AAJ-4576-2021; AAJ-4623-2021Study objective: There has been a gradual decline in the number of case reports published in leading medical journals in recent years. Since case reports are not highly cited they have an adverse effect on the journal impact factor. On the other hand sharing new experiences, challenges, or discoveries with colleagues is essential for medical community. Should case reports be eliminated from the journals or published only in journals devoted to case reports? Design: Observational study. Setting: Web of Science database was searched, between 2005 and 2009, with terms: "anesthesia", "anesthesiology" and "case report" yielding 25 969, 9532, and 661 publications, respectively. Since some reports contained large number of cases, only those involving up to three cases (n = 425) were evaluated by the authors with respect to their type, contribution to knowledge and/or practice (Likert scale) and times they were cited. Main results: Distribution of answers to the statement "Case has added to my knowledge and/or improved my practice" was; 3% (strongly disagree), 10.5% (disagree), 33.2% (neither agree nor disagree), 39.3% (agree) and 13.7% (strongly agree). Average citations per item was 4.43 (1883/425), 7.32 (4838/661), and 7.82 (74 529/ 9532). As to the types of the reports; 50% unexpected event in the course of anesthesia, 31% unusual and instructive cases, 9.6% novel/unique anesthetic techniques, 6% novel use of equipment, 1.6% new information on diseases of importance to anesthesiology and 1% scientific observations. Conclusion: Case reports have been an important source of clinical guidance and scientific insight, and play an important role in medical education. They can be published quickly, providing publication opportunity for juniors and for clinicians who may not have the time or finance to conduct large-scale research. On the other hand some argue, that case reports are irrelevant in current medical practice and education, being at the bottom of the hierarchical ladder of medical evidence. We conclude that case reports should not be done away with but be published in websites and journals like the venue to be launched in 2013 by the International Anesthesia Research Society, devoted entirely to them to meet the need for the publication of interesting cases.

Design: Prospective, randomized, and controlled study. Setting: Tertiary, university hospital. Patients: In total, 180 pediatric patients, American Society of Anesthesiologists physical status I and II, who were scheduled for dental procedures of tooth extraction, filling, amputation, and root treatment. Interventions: Patients were categorized into 3 groups: music, isolation, and control. During the procedures, the patients in the music group listened to Vivaldi's The Four Seasons violin concertos by sound isolating headphones, whereas the patients in the isolation group wore the headphones but did not listen to music. All patients were sedated by 0.1 mg/kg midazolam and 1 mg/kg propofol. During the procedure, an additional 0.5 mg/kg propofol was administered as required. Measurements and main results: Bispectral index was used for quantifying the depth of sedation, and total dosage of the propofol was used for sedative requirements. The patients' heart rates, oxygen saturations, and Observer's Assessment of Alertness and Sedation Scale and bispectral index scores, which were monitored during the operation, were similar among the groups. In terms of the amount of propofol used, the groups were similar. Prolonged postoperative recovery cases were found to be significantly frequent in the control group, according to the recovery duration measurements (P = .004). Conclusions: Listening to music or providing sound isolation during pediatric dental interventions did not alter the sedation level, amount of medication, and hemodynamic variables significantly. This result might be due to the deep sedation levels reached during the procedures. However, listening to music and providing sound isolation might have contributed in shortening the postoperative recovery duration of the patients. (C) 2016 Elsevier Inc.
