Case Reports
Arrhythmias and ECG changes in life threatening hyperkalemia in older patients treated by potassium sparing drugs.
Severe hyperkalemia is a life threatening condition that can cause fatal rhythm disturbance and terminal heart arrest. The most common cause of hyperkalemia in older patients is that of iatrogenic medication-related etiology due to associated polymorbidity, polypharmacy and reduced reserve metabolic capacity. The aim of this paper is to increase awareness in the clinicians of the risk of hyperkalemia in elderly patients treated by potassium sparing drugs. ⋯ Potassium sparing drug therapy in older persons requires more frequent monitoring especially when drugs or their doses are changed, or during concomitant acute illness.

Comparative Study
Peripheral tissue oxygenation during standard CPB and miniaturized CPB (direct oxymetric tissue perfusion monitoring study).
The aim of this study was to compare the impact of standard cardiopulmonary bypass (CPB) with mini CPB on peripheral tissue perfusion. ⋯ Mini CPB enables perfusion with a relatively low flow. The results of this study suggest that a flow decrease in mini CPB is well tolerated by the organism.

Comparative Study
Comparison of functional fibrinogen assessment using thromboelastography with the standard von Clauss method.
To compare assessment of fibrinogen by thromboelastography with the standard von Clauss method. ⋯ The functional fibrinogen test is a valid point-of-care method for fibrinogen assay with a moderate correlation to the standard method.

To evaluate the ability of hybrid 18F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) to predict histopathological response and overall survival (OS) after preoperative neoadjuvant chemoradiotherapy (CRT) in patients with the esophageal carcinoma. ⋯ No statistically significant correlation was found between the (18)F-FDG metabolic response after the neoadjuvant CRT and histopathological response. Presently, the contribution of (18)F-FDG PET/CT as a marker of the potential result of CRT cannot be considered definite. Another study with a larger sample of patients and standardized algorithms for the examining protocols would be necessary for reaching definitive conclusions.

Randomized Controlled Trial Comparative Study
Comparative study of intravenous opioid consumption in the postoperative period.
Intravenous patient-controlled analgesia (IV PCA) using opiods is an accepted method for delivering postoperative analgesia. The aim of this study was to compare fentanyl and tramadol with IV PCA after spinal anesthesia (SA) and general anesthesia (GA) following cesarean section (C/S). ⋯ Our study shows that analgesic consumption and post-operative pain scores after SA in C/S decreased, without increase in adverse reactions.
