RESUMEN
Objective: This study aimed to investigate the necessity of using fluoroscopy in retrograde intrarenal surgery (RIRS). Material and Methods. A total of 612 patients who underwent RIRS for kidney stones were evaluated and divided into two groups. Group 1 routinely underwent the operation with fluoroscopy due to opaque stones (n: 504). In group 2, the procedure was performed without fluoroscopy because of nonopaque stones (n: 108). Both groups were assessed for stone size, location, and number. Success and complication rates were compared between the two groups. Conclusion: This study was designed with the thought of not using fluoroscopy in RIRS patients with nonopaque stones and having the same stone-free rates in opaque stones. In the statistical analysis, there was no difference between the groups with and without scope for stone side, size, localization, and number; likewise, the complication rates developed in the comparison of both groups, stone-free rates, and hospital stay were the same. Discussion. Advances in the calibration of instruments, the development of optical systems, and improvements in imaging system resolution have gradually reduced the need for fluoroscopy in RIRS. This study provides further evidence that fluoroscopy is unnecessary in RIRS procedures, thereby eliminating unnecessary radiation exposure.

Background Vitrectomy surgery is a painful and lengthy procedure. Therefore, administering sedation to reduce patient agitation provides both surgical comfort and hemodynamic stability. However, various complications can arise during the perioperative period depending on the sedation agent used. In our study, we aimed to evaluate the effects of dexmedetomidine and remifentanil sedation applications on patient hemodynamics and perioperative complications in vitrectomy surgery. Methods Our retrospective study included patients aged 18-70 who underwent vitrectomy surgery between 2021 and 2022 with complete file data and ASA scores of 1-3 after obtaining approval from our hospital's ethics committee. Patients were classified into two groups based on the sedation agent used: Group D for dexmedetomidine and Group R for remifentanil. Demographic data of patients, heart rate, mean arterial pressure, oxygen saturation, and bispectral index values during perioperative monitoring, operation duration, and complications such as perioperative nausea, vomiting, and low saturation were recorded. The data of both groups were statistically evaluated, with p<0.05 values considered statistically significant. Results Because of missing data in 18 out of 58 patient files, these cases were excluded from the study. A total of 40 patients were included in the study, with 20 in Group D and 20 in Group R. The mean age of the patients was 64. Among them, 18 (45%) were male, and 22 (55%) were female. The mean operation duration was 61.8 ± 24.1 minutes in Group D and 56.3 ± 17.2 minutes in Group R. The heart rate in Group D was statistically significantly lower than in Group R, starting from the 20th minute of the perioperative period. There were no significant differences between the groups in terms of mean arterial pressure, oxygen saturation, and bispectral index values. One case of bradycardia occurred in Group D, requiring intervention. Conclusion In vitrectomy surgery, both dexmedetomidine and remifentanil infusions can be used for sedation, but caution is advised regarding bradycardia in Group D. Anticipating potential complications with an experienced anesthesia team is crucial for both patient and surgical comfort.
RESUMEN
BACKGROUND: Severe burn injuries are a major health problem globally. A profound and prolonged hypermetabolic response develops in severe burn injuries and it is crucial to monitor the patients' energy requirements in order to meet them adequately. The aim of the present study was to examine the energy changes during the acute phase using the indirect calorimetry (IC) method in severe burn patients. METHODS: The study included 15 severe burn patients. Patients with FiO2 >60%, tube thoracostomy, closed underwater drain (CUWD) and air leakage were excluded from the study. Patients' demographic data, burn percentages, burn types, duration of stay in intensive care, mortality and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores were recorded. Indirect calorimeter measurements were taken once from the patients upon their first arrival and during the following four weeks. Resting energy expenditure (REE), basal metabolic rate (BMR), oxygen consumption (VO2), carbon dioxide production (VCO2), body temperatures, presence of sepsis, Sequential Organ Failure Assessment (SOFA) and Modified Nutrition Risk in Critically Ill (mNUTRIC) scores were recorded. The data were analysed using SPSS 24 and p-values <0.05 were considered statistically significant. RESULTS: In the study, 13 (86.67%) of the patients were male. Patients' mean age was 45.27±18.16 years, and mean BMI 25.99±4.22 kg/m2. Five patients (33.33%) had chronic diseases. The average burn percentage was 45%, with 7 (46.67%) patients having a burn percentage of ≤40%, while 8 (53.33%) had a burn percentage of >40%. A total of 14 (93.33%) had flame burns; 3 (20.00%) patients deceased, and 12 (80.00%) were discharged. The mean APACHE II score was 11.53±6.83. The measured mean values of REE, VO2, VCO2 and fever were seen to be the highest in the first week after admission and decreases were observed in the subsequent weeks. SOFA score averages were the highest at admission, and decreased in the following weeks. CONCLUSION: Severe burn patients were observed to go through the hypermetabolic process in the acute phase and their energy requirements were high particularly in the first week. It was concluded that regular IC monitoring can be beneficial to fully meet the energy requirements of severe burn patients due to the prolonged hypermetabolic process.
RESUMEN
BACKGROUND: This study was designed to investigate the prophylactic and therapeutic effects of hyaluronic acid and chondroitin sulfate combination (HA/CS) on a model of acute radiation proctitis. METHODS: Rats were divided into five groups: SHAM; irradiation (IR) + saline (1 mL for 5th and 10th day); IR + HA/CS (1 mL for 5th and 10th day). A single fraction of 17.5 Gy was delivered to each rat. HA/CS was administered rectally each day after irradiation. Each rat was observed daily for signs of proctitis. Irradiated rats were euthanized on days 5 and 10. The mucosal changes were evaluated macroscopically and pathologically. RESULTS: According to the clinical findings, five rats in the irradiation + saline group showed grade 3-4 symptoms on the 10th day. No significant difference in the macroscopic finding scores on the 5th day was observed between the irradiation + saline and irradiation + HA/CS groups. In the pathological examination, radiation-induced mucosal damage was the most prominent finding 10 days after irradiation in saline-treated rats. On the 10th day, the irradiation + HA/CS group showed mild inflammation and slight crypt changes, which corresponded to grade 1-2 pathological findings. CONCLUSION: We think that HA/CS used in radiation cystitis can be beneficial for radiation proctitis.

BACKGROUND: Acute kidney injury (AKI) is one of the common complications, associated with high mortality and morbidity in patients with burn injuries. This study aimed to determine the frequency of AKI development, its affective factors, and mortality rates according to kidney disease improving global outcomes (KDIGO) criteria in the burn patients. METHODS: The study included patients who are hospitalized for at least 48 h and aged >18 years, whereas patients with a renal transplant, chronic renal failure, undergoing hemodialysis, <18 years of age, with a glomerular filtration rate of <15 on admission, and toxic epidermal necrolysis was excluded from the study. KDIGO criteria were used to evaluate the occurrence of AKI. Burn mech-anism, total body surface area, inhalation injury respiratory tract burn, fluid replacement at 72 h with Parkland Formula, mechanical ventilator support, inotrope/vasopressor support, intensive care unit, lenght of stay, mortality, abbreviated burn severity index (ABSI), acute physiology, and chronic health evaluation II (APACHE II) ve Sequential organ failure assessment (SOFA) were recorded. RESULTS: A total of 48 patients were included in our study, of which 26 (54.2%) developed AKI (+), whereas 22 (45.8%) did not (-). The mean total burn surface area was 47.30% in the AKI (+) group and 19.88% in the AKI (-) group. Mean scores of ABSI, II (APACHE II), and SOFA, the mechanical ventilation and inotrope/vasopressor support and the presence of sepsis were significantly higher in the AKI (+). No mortality was determined in the AKI (-) group, whereas 34.6% in the AKI (+) group which was significantly high. CONCLUSION: AKI was related to high morbidity and mortality in patients with burns. Using KDIGOs, classification in daily fol-low-up is useful in early diagnosis.
