Role of augmenter of liver regeneration on testicular ischemia and ischemia/reperfusion injury: An experimental study.

Background: Testicular torsion causes ischemic injury, and torsion causes reperfusion injury. Aim: Evaluating the role of augmenter of liver regeneration (ALR) in testicular ischemia and ischemia/reperfusion injury. Materials and Method(s): Seventy-eight (78) healthy Wistar albino male rats were randomly divided into four groups; control (C) (n = 6), sham (S) (n = 24), torsion (T) (n = 24), and torsion/detorsion (T/D) (n = 24). S, T, and T/D groups were divided into four subgroups (n = 6) as 1st, 2nd, 3rd, and 4th hours. Blood, tissue ALR, and histology analyses were performed between groups and subgroups. Results: The increase in plasma ALR values at the 3rd and 4th hours compared to the 1st hour in the T group were significant (P < 0.01, P < 0.001, respectively). In the T/D group, a significant increase was observed in plasma ALR values at the 3rd and 4th hours compared to the 1st hour (P < 0.05, P < 0.001, respectively). Plasma ALR values at the 1st, 2nd, 3rd, and 4th hours were higher in the T and T/D groups than in the C group (P < 0.001, P < 0.05, respectively). Plasma ALR values were higher in the T group at the 1st, 2nd, 3rd, and 4th hours than in the S group (P < 0.05). A significant increase was observed in tissue ALR at the 3rd and 4th hours than at the 1st hour in the T group (P < 0.05, P < 0.001, respectively). A significant increase was observed in tissue ALR at the 3rd and 4th hours than in the 1st hour in the T/D group (P < 0.05, P < 0.001, respectively). Discussion: ALR in plasma and testicular tissue has a potential role in the early diagnosis of testicular torsion and in predicting the prognosis of T and T/D.

An analysis of patients in palliative care with pressure injuries.

AIM: The aim of this study was to evaluate the factors that are effective for the treatment, recovery of pressure injury (PI) and costs in palliative care (PC) patients. MATERIALS AND METHODS: From a retrospective review of patient records, the PI localization, the presence of infection, PI stage on admission, discharge and treatment costs were recorded. Patients were grouped according to diagnoses, and PI localizations (sacrum, trochanter, ischium, and heel). The comparison was made of changes in wound stage in the groups. RESULTS: PI was present in all 154 patients during hospitalization and in 94 (61%) on discharge. Full recovery was determined in 52/129 (40.3%) patients with PI in the sacrum, in 23/46 (50%) in the trochanter, in 22/40 (55.0%) in the heel, and in 10/12 (83.3%) in the ischium. Worsening PI stage was observed in 5 (3.9%) in the sacrum, in 1 in the trochanter and in 4 in the heel. Improvement in PI stage was seen in 96 (74.4%) in the sacrum, in 35 (3.9%) in the trochanter, in 27 (50.5%) in the heel, and in 10 (83.3%) in the ischium. Regardless of wound localization, the improvement was observed in 168 (74%) of 227 PI and worsening in 10 (4.4%). The group with no change in the PI stage had prolonged hospital stay and higher costs. The Karnovsky Performance Score and Glasgow Coma Score of fully recovered patients were determined to be higher, and no statistically significant difference was seen in respect of age. CONCLUSIONS: PC patients are prone to PI due to many chronic diseases. The localization of PI and infection are effective factors in the healing of ulcers. The treatment costs for PC patients is higher if they have a pressure ulcer. More comprehensive studies will be useful to clarify the economic and social dimensions of this issue.

Effects of intrathecal bupivacaine and bupivacaine plus sufentanil in elderly patients undergoing transurethral resection.

INTRODUCTION: The present study compared the effect of bupivacaine and bupivacaine + sufentanil on hemodynamic parameters and characteristics of spinal anesthesia in elderly patients undergoing transurethral resection of the prostate (TURP) under spinal anesthesia. TECHNICAL CONSIDERATIONS: The study included 40 American Society of Anesthesiologists (ASA) I-III patients scheduled to undergo TURP. Patients were blindly and randomly divided into two groups. Group B (n = 20) received 10 mg of intrathecal bupivacaine and group BS (n = 20) received 7.5 mg of bupivacaine + 5 µg of sufentanil. Sensory and motor block characteristics, hemodynamic changes, side effects, and time to first analgesic requirement were recorded. No differences in mean arterial pressure or heart rate, time for sensory blockade to reach the T10 level, and maximum sensory level were observed between the two groups. The time to first analgesic request was longer in group BS (P < 0.05). Motor block was significantly higher in group B (P < 0.05). In terms of side effects, no statistically significant differences occurred between the groups. CONCLUSIONS: Similar hemodynamic stability and sufficient level of sensory blockade were provided by bupivacaine and bupivacaine + sufentanil used for spinal anesthesia in patients undergoing TUR. Due to the fact that less motor block was observed and the time to first analgesic request was longer, the combination of bupivacaine + sufentanil might be appropriate for patients undergoing TUR.

The effect of thrombolytic therapy on QT dispersion in acute myocardial infarction and its role in the prediction of reperfusion arrhythmias.

PURPOSE: We aimed to determine the effect of intravenous thrombolytic therapy on QT dispersion (QTd) and its role in the prediction of reperfusion arrhythmias. MATERIALS AND METHODS: Twenty patients with acute myocardial infarction (MI) were enrolled in the study. Measurements of QTd were carried out prior to thrombolytic therapy and before discharge. The patients were examined for ventricular arrhythmias with 24-h Holter electrocardiography monitoring after treatment and the relationship between ventricular arrhythmias and the QTd values in the early phase of MI was investigated. RESULTS: The values of QTd were significantly higher during the early phase of MI (60 ± 5.32 ms) than those in the late phase (53.35 ± 4.07 ms) (P = 0.032). There was no correlation between isolated, bigeminal, trigeminal and total ventricular premature beats, accelerated idioventricular rhythm (AIVR) with QTd values. However, the patients with sustained ventricular tachycardia (VT), prolonged VT and sustained AIVR had higher corrected QTd (92 ms 1/2 , 97.8 ms 1/2 , 81.7 ms 1/2 , respectively) than the patients without these arrhythmias (74 ms 1/2 , 56.3 ms 1/2 , 58.28 ms 1/2 , respectively) (P = 0.022, 0.013, 0.018). CONCLUSION: The values of QTd may be significantly reduced in the 1 st week of acute MI and measurement of QTd in the early phase of MI may have a correlation with the following reperfusion arrhythmias: Sustained VT, prolonged VT and AIVR.

The effect of anesthesia type on stress hormone response: comparison of general versus epidural anesthesia.

AIM: The aim of this study was to investigate the effect of different types of anesthesia on stress hormones. MATERIALS AND METHODS: The study was included 60 ASAI-II cases scheduled for major lower extremity surgery. The cases were randomized into 2 groups: The EA group was administered epidural anesthesia and the GA group was administered standard general anesthesia. In order to evaluate the surgical trauma - related stress response, CRP, TSH, cortisol, and fasting blood sugar(FBS) levels were measured preoperatively, 30 min after surgical incision, and 24 h post surgery. RESULTS: Between-group comparisons; Preoperative values were not significantly different between the groups.( P > 0,05) Pulse rate and cortisol values significantly higher in general group at 30 min. ( P < 0,05), and the FBS values were significantly higher in the epidural group at 24 h.( P < 0,05) There were not found differences for other parameters at evaluation times. CONCLUSION: No differences were observed between the two anesthesia methods, in terms of minimizing the stress response due to surgical trauma during major low extremity surgery.
