RESUMO

OBJECTIVE: Pain after cardiac surgery is a frequently encountered morbidity associated with poor quality of life and postoperative recovery. There have been several regional anesthesia modalities for this purpose. We aimed to investigate acute and chronic postoperative analgesic effects of erector spinae plane block (ESPB) after cardiac surgery. PATIENTS AND METHODS: We retrospectively evaluated patients who underwent cardiac surgery between December 2019 and December 2020. According to regional anesthesia management, there were two groups: ESPB and control groups. Patient demographic data, surgical outcomes, and Numerical Rating Scale (NRS) and Prince Henry Hospital Pain Scores (PHHPS) were recorded. RESULTS: Patients in the ESPB group were significantly younger than those in the control group (p=0.023). The duration of surgery was significantly shorter in the ESPB group (p=0.009). Patients in the ESPB group had significantly lower NRS and PHHPS pain scores assessed at the 48th hour after extubation (p=0.001 for both cases) and three months after discharge (p<0.001 and p=0.025, respectively). Significance remained after adjustment for age (p=0.029 and p<0.001, respectively) and duration of surgery (p=0.003 and p=0.041, respectively). CONCLUSIONS: ESPB might benefit patients with cardiac surgery by reducing acute and chronic postoperative pain.

RESUMO

AIM/INTRODUCTION: Analgesic, anti-inflammatory and anti-apoptotic effects of pregabalin have been shown previously. In this study, we investigated the protective effect of different doses of pregabalin on skeletal muscle IR injury in rats. MATERIALS AND METHODS: 24 rats were randomly divided into 4 groups (Control, Ischaemia-Reperfusion (IR), IR-Pregabalin 50 mg, IR-Pregabalin 200 mg). Following IR, serum Ischemia Modified Albumin (IMA) and tissue Paraoxonase (PON) were studied and gastrocnemius muscle tissue was removed for histopathologic examination. RESULTS: Interstitial inflammation was higher in the IR group than in the control and Pregabalin 200 mg groups (p = 0.037, p = 0.037, respectively). Congestion was higher in the IR group than in the control, Pregabalin 50 and 200 mg groups (p = 0.001, p = 0.004, p = 0.004, respectively). PON was lower in the IR group than in the Control, Pregabalin 50 and 200 mg groups (p = 0.001, p = 0.007, p = 0.015, respectively). IMA was higher in the IR group than in the Control, Pregabalin 50 and 200 mg groups (p < 0.0001, all). CONCLUSION: We think that administration of pregabalin, more prominent at 200 mg, can reverse the injury that occurs in the skeletal muscle of IR-induced rats. Pregabalin can be safely used for analgesia in cases of IR (Tab. 2, Fig. 9, Ref. 41).

RESUMO

OBJECTIVE: The Bethesda classification was introduced in 2008 to provide standardisation in the evaluation of thyroid fine needle aspiration cytology (FNAC). We compared the diagnostic value of pre-Bethesda and Bethesda classification systems in the differentiation of benign and malignant thyroid nodules. METHODS: Medical records of patients who underwent a thyroidectomy between June 2007 and June 2014 were reviewed retrospectively. Nodules evaluated with FNAC before March 2010 were classified as pre-Bethesda (non-diagnostic, benign, indeterminate, suspicious for malignancy and malignant), and those evaluated after March 2010 were considered Bethesda (non-diagnostic, benign, atypia of undetermined significance/follicular lesion of undetermined significance, follicular neoplasia/suspicious for follicular neoplasia, suspicious for malignancy and malignant). Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of the two classification systems were calculated. RESULTS: There were 1810 nodules in the pre-Bethesda and 5115 nodules in the Bethesda group. The non-diagnostic rate was significantly higher, and benign and suspicious for malignancy rates were lower in Bethesda compared with the pre-Bethesda group (P<.001 for each). When benign cytology was considered negative, and indeterminate, follicular neoplasia/suspicious for follicular neoplasia, suspicious for malignancy and malignant cytologies were considered positive, results for pre-Bethesda and Bethesda were as follows: sensitivity, 78.9% and 78.5%; specificity, 86.6% and 97.0%; PPV, 42.8% and 72.6%; NPV, 97% and 97.8%; and accuracy, 85.7% and 95.3%, respectively. CONCLUSIONS: Among operated nodules, percentages of benign and suspicious for malignancy cytologies decreased, and percentages of non-diagnostic and uncertain cytologies increased with the implementation of Bethesda. The diagnostic value of FNAC seems to have increased with the use of Bethesda classification.

RESUMO

BACKGROUND: A fine needle aspiration biopsy (FNAB) is the most valuable diagnostic procedure for pre-operative discrimination of benign and malignant nodules. The Bethesda System for Reporting Thyroid Cytopathology provides standardised reporting and cytomorphological criteria in aspiration smears. The aim of the present study was to determine malignancy rates in nodules with different cytology results and evaluate the diagnostic value of Bethesda for variants of papillary thyroid carcinoma (PTC). MATERIALS AND METHODS: A retrospective analysis of 2534 cases with 5784 thyroid nodules, who underwent FNAB followed by surgery, were included in this study. FNAB was performed with ultrasonography guidance. Cytological diagnoses were classified as: non-diagnostic (ND), benign, atypia of undetermined significance/follicular lesions of undetermined significance (AUS/FLUS), follicular neoplasm/suspicious for follicular neoplasm (FN/SFN), suspicious for malignancy (SUS) and malignant. Histopathological diagnoses were classified into four groups: benign, PTC, follicular thyroid cancer and other types of thyroid cancer (including medullary thyroid cancer, undifferentiated thyroid cancer and thyroid tumours of uncertain malignant potential). Cases with PTC were further divided into four categories: conventional variant, follicular variant, aggressive variants (tall cell, diffuse sclerosing and columnar variant) and other variants (oncocytic, solid/trabecular and warthin-like variants). FNAB results were compared with histopathological results. RESULTS: Malignancy rates were 6.3%, 3.2%, 20.7%, 33.3%, 74.2% and 95.6% in the nodules with ND, benign, AUS/FLUS, FN/SFN, SUS and malignant cytology results, respectively. Pre-operative cytology was malignant or SUS in 56.6% of conventional, 24.3% of follicular, 92% of aggressive and 41.7% of other variants of histopathologically confirmed PTC. The difference between the groups was significant (P < 0.001). CONCLUSION: The Bethesda classification is a reliable indicator of malignancy in nodules with different cytology results and seems to be very effective in predicting the malignancy for the nodules diagnosed with aggressive variant PTC on the final histological examination.

RESUMO

We aimed to determine serum soluble Fas antigen (sFas) levels at various stages of hepatitis C virus (HCV)-induced liver disease, and investigate correlations between serum sFas levels and clinical, biochemical and pathologic features. Sixty-five patients were categorized into five groups: 1, chronic active hepatitis C, elevated alanine aminotransferase (ALT), HCV-polymerase chain reaction (PCR) positive; 2, responders to interferon + ribavirin therapy; 3, cirrhosis; 4, chronic hepatitis C, normal ALT, HVC-PCR positive; and 5, sustained responders. Group 6 comprised 15 control individuals. Serum sFas levels were measured by enzyme-linked immunosorbent assay. Significant differences in serum sFas levels were found between the following groups: 1 and 2; 1 and 3; 1 and 4; 1 and 6; and 3 and 6. Serum sFas levels did not correlate with ALT, histological activity or HCV-PCR positivity within group 1. Serum sFas levels appear to increase in advanced stages of HCV-induced liver disease, as a result of host-related immunological factors.
