Comparison of transoral endoscopic thyroidectomy vestibular approach and open conventional thyroidectomy regarding inflammatory responses, pain, and patient satisfaction: a prospective study.

Introduction: The application of transoral endoscopic thyroidectomy vestibular approach (TOETVA) is becoming widespread throughout the world. We primarily aimed to evaluate the severity of surgical trauma in TOETVA and conventional open thyroidectomy (COT) regarding the inflammatory response including the comparison of surgical stress markers [interleukin-6 (IL-6), C-reactive protein (CRP), white blood cell (WBC)]. Material and method: This non-randomized prospective study enrolled two groups with 20 patients each: COT group and TOETVA group. Patients aged 18-65 years with benign thyroid disease; with fine needle aspiration biopsy results of Bethesda III, IV or Bethesda V, VI (<1 cm nodule); thyroid volume <50 cm3; nodule diameter <4 cm; female gender without a previous neck, chin, and/or oral surgery; without vocal cord paralysis preoperatively; and patients in euthyroid state were enrolled to the study. Preoperative, postoperative second hour, first day, and second day CRP, WBC, and IL-6 levels were evaluated. Pain intensity was evaluated with the visual analog scale (VAS) score on the 2nd and 12th hour, 1st and 2nd days postoperatively. Results: All the patients were female and mean age was significantly higher in the COT group. The operative time was significantly longer in the TOETVA group. No significant difference was found between the two groups regarding IL-6 levels. In the TOETVA group, postoperative second hour WBC value (p = 0.044) and first (p = 0.002) and second day (p = 0.005) CRP values were significantly higher. In the TOETVA group, the lower lip and lower chin VAS scores were significantly higher at 2nd and 12th hour, on the first and second days. The anterior neck VAS score was significantly higher in the TOETVA group at the second hour (p = 0.025). General and cosmetic satisfactions were similar at the 15th and 30th days in both groups. Conclusion: The longer operative time and higher postoperative CRP level and VAS score in the chin and lower lip in the TOETVA group suggested that the method is not a minimally invasive technique compared to COT. However, the presence of similar total complication rates and early postoperative general and esthetic satisfaction that improves over time in both groups suggests that the clinical effect of increased magnitude of systemic inflammatory response in TOETVA might be temporary and acceptable.

Effect of Reduction Mammoplasty on Insulin and Lipid Metabolism in the Postoperative Third month: Compensatory Hip Enlargement.

BACKGROUNDS: The positive effects of reduction mammoplasty on metabolic profile have been shown in a limited number of studies. This study objective to reveal the effects of reduction mammoplasty on metabolic profile and anthropometric measurements. SUBJECTS AND METHOD: The study was prospectively conducted on 42 patients who were operated between April 2019 and March 2020. Fasting plasma glucose, fasting plasma insulin, total cholesterol, triglyceride, high-density lipoprotein and low-density lipoprotein cholesterol, HgA1c, homeostasis model assessment scores, adiponectin, leptin, and resistin levels were evaluated. In addition, age, height, weight, body mass index; breast, chest, waist, hip circumference; waist-hip ratio, and bilateral breast resection tissue weights were recorded. Data and blood samples were collected one hour before the operation, 6 and 12 weeks after the operation. RESULT: The patients' mean age was 43.14±10.24, and their average height was 159.42±4.96 cm. The excised bilateral dermo fatty tissue weight was 1435.85±721.16 g. At the postoperative 40th day a decrease in leptin (p = 0.001), resistin (p =0.008), glucose (p = 0.021) and insulin resistance values (p=0.013) stated. There was an increase in adiponectin (p < 0.001) and HDL (p = 0.013) levels at the postoperative 40th day. In the postoperative third month, these data returned to the previous levels that were measured before operations. However, an increase in hip circumference (p = 0.034) and a decrease in waist-hip ratio (p < 0.001) was detected in third month. Also, there was no difference in body mass index and weight compared to pre-operation. CONCLUSION: After reduction mammoplasty, compensatory fat growth in the hip area, an increase in the hip circumference, and a decrease in the waist-hip ratio were observed in the postoperative third month.

The effect of sarcopenia and serum myokines on prognosis and survival in cirrhotic patients: a multicenter cross-sectional study.

OBJECTIVE: Sarcopenia is one of the most significant contributors to morbidity in patients with chronic liver disease. Serum myokines are potential biomarkers for detecting early sarcopenia. We aimed to investigate the relationship between serum myokines and cirrhosis-related mortality in the early stages of the disease. METHODS: In total, 262 patients and 50 healthy controls were enrolled in this study, which was designed as a multicenter cross-sectional study. At the beginning of the study, sarcopenia was defined by computed tomography scans using the third lumbar vertebra skeletal muscle index. Serum myostatin, irisin, and follistatin levels, nutritional status of the patients, and muscle strength as measured by the handgrip test were recorded. Cirrhosis-related mortality and overall survival were evaluated in the fourth year of the study as the second checkpoint of cross-sectional analysis. RESULTS: A total of 145 (55.3%) patients were diagnosed with sarcopenia. Multivariate analysis revealed that low BMI, high levels of myostatin, and decreased irisin levels were independent predictors of sarcopenia. While serum irisin level was the most predictive parameter in terms of 4th-year cirrhosis-related mortality in the CHILD A group, serum myostatin levels were found more indicative in the CHILD BC group regardless of sarcopenia status ( P < 0.001). CONCLUSION: Serum myostatin levels predict sarcopenia in all stages of cirrhosis. Serum irisin levels can also be used as a potential biomarker to predict both treatable sarcopenia and cirrhosis-related mortality in CHILD A patients.

Asymmetric Dimethylarginine in COPD Exacerbation.

Objectives: Chronic obstructive pulmonary disease (COPD) is a disease with progressive airway limitation. The asymmetric dimethylarginine (ADMA) molecule is known to be effective in airway inflammation and remodeling. We investigated the relationship between ADMA and COPD, and its role in the course of the disease in cases with exacerbation. Methods: This single-center study performed in our patient clinic included 56 patients (57.1% of males) with median age 67 (41-88) presented with COPD exacerbation and 26 sex-matched healthy controls. ADMA, white blood cell count, eosinophil, neutrophil, lymphocyte, C-reactive protein, fibrinogen, oxygen saturation%, and pulmonary function test values were compared. Results: ADMA values were significantly higher (516.93 vs. 320.05 median, p<0.05) in the COPD group compared to the control group. No significant difference was demonstrated in ADMA concentrations according to Global Initiative for Chronic Obstructive Lung Disease Stages (p>0.05). In the receiver operating characteristic analysis to estimate the predictive power of COPD, the cutoff ADMA concentration >301 ng/ml was found to be able to distinguish COPD patients in all cases. Conclusion: ADMA levels increase with complex mechanisms in COPD. It can be a significant indicator of the disease. However, more extensive research is needed for its use as a biomarker in severity and progression of COPD.

The Potential Therapeutic Effects of Agmatine, Methylprednisolone, and Rapamycin on Experimental Spinal Cord Injury.

OBJECTIVE: In spinal cord injury (SCI), the primary mechanical damage leads to a neuroinflammatory response and the secondary neuronal injury occurs in response to the release of reactive oxygen species (ROS). In addition to the suppression of inflammation, autophagy plays a significant role in the survival of neurons during secondary SCI. The present study aimed to examine the anti-inflammatory and autophagic effects of agmatine and rapamycin in SCI and to compare the results with methylprednisolone (MP) used in the clinic. MATERIALS AND METHODS: In this animal-based experimental study, thirty adult male Sprague-Dawley rats were randomly divided into five groups as sham-control, injury, injury+MP, injury+rapamycin, injury+agmatine groups. SCI was induced by compressing the T7-8-9 segments of the spinal cord, using an aneurysm clip for one minute, and then rats were treated daily for 7 days. Seven days post-treatment, damaged spinal cord tissues of sacrificed rats were collected for microscopic and biochemical examinations using histopathologic and transmission electron microscope (TEM) scores. Malondialdehyde (MDA) and glutathione peroxidase (GPx) levels were spectrophotometrically measured. RESULTS: The results of this study showed that the damaged area was smaller in the rapamycin group when compared to the MP group. Many autophagic vacuoles and macrophages were observed in the rapamycin group. Degeneration of axon, myelin, and wide edema was observed in SCI by electron microscopic observations. Fragmented myelin lamellae and contracted axons were also noted. While MDA and GPx levels were increased in the injury group, MDA levels were significantly decreased in the agmatine and MP groups, and GPx levels were decreased in the rapamycin group. CONCLUSION: The results of our study confirmed that rapamycin and agmatine can be an effective treatment for secondary injury of SCI.

More than a skin disease: stress, depression, anxiety levels, and serum neurotrophins in lichen simplex chronicus

Abstract Background: Lichen simplex chronicus is a dermatological condition due to excessive scratching, with few studies on psychoneuroimmunology. Objective: We aimed to estimate the levels of stress, depression, and anxiety, and to measure serum levels of neurotrophins in patients with lichen simplex chronicus, and to correlate these parameters with the severity of the disease and pruritus. Methods: Thirty-six patients with lichen simplex chronicus and 36 age- and sex-matched healthy controls were included. Each participant was administered the Hospital Anxiety and Depression Scale and Perceived Stress Scale questionnaires, along with a visual analog scale for pruritus. Levels of neurotrophins (brain-derived neurotrophic factor, neurotrophin-3, nerve growth factor, glial cell line-derived neurotrophic factor) were determined by ELISA assays. Results: The scores of Perceived Stress Scale-10, Hospital Anxiety and Depression Scale were statistically higher in patients (p < 0.05 for all). The serum levels of all neurotrophins were significantly lower in patients compared to healthy controls (p < 0.05 for all). Disease severity showed no correlation with all four neurotrophins. In linear regression models applied for increased visual analog scale-pruritus scores and disease severity these two variables were statistically significant predictors (p = 0.043). Study limitations: A direct causal relationship was not addressed. Conclusion: Lichen simplex chronicus patients are at risk of increased levels of stress, anxiety, depression, and present decreased levels of neurotrophins, that may suggest a role in the pathophysiology of this disorder.

The relationship between serum erythropoietin, hepcidin, and haptoglobin levels with disease severity and other biochemical values in patients with COVID-19.

INTRODUCTION: Studies have shown that iron metabolism is affected by coronavirus disease 19 (COVID-19), which has spread worldwide and has become a global health problem. Our study aimed to evaluate the relationship between COVID-19 and serum erythropoietin (EPO), hepcidin, and haptoglobin (Hpt) levels with disease severity, and other biochemical values. METHODS: Fifty nine COVID-19 patients hospitalized in the intensive care unit (ICU) and wards in our hospital between March and June 2020 and 19 healthy volunteers were included in the study. Participants were divided into mild, severe, and critical disease severity groups. Group mean values were analyzed with SPSS according to disease severity, mortality, and intubation status. RESULTS: Hemoglobin (Hb) levels were significantly lower in the critical patient group (P < .0001) and deceased group (P < .0001). The red blood cell distribution width-coefficient of variation (RDW-CV) and ferritin values were significantly higher in the intubated (P = .001, P = .005) and deceased (P = .014, P = .003) groups. Ferritin values were positively correlated with disease severity (P < .0001). Serum iron levels were lower in the patient group compared with the reference range. (P < .0001). It was found that the transferrin saturation (TfSat) was lower in the patient group compared with the control group (P < .0001). It was found that the mean EPO of the deceased was lower than the control group and the survived patient group (P = .035). Hepcidin levels were found to be significantly lower in the patient group (P < .0001). Hpt values were found to be significantly lower in the intubated group (P = .004) and the deceased group (P = .042). CONCLUSION: In our study, while serum iron and hepcidin levels decreased in patients diagnosed with COVID-19, we found that EPO and Hpt levels were significantly lower in critical and deceased patient groups. Our study is the first study examining EPO and Hpt levels in patients diagnosed with COVID-19.

Serum fibrosis markers could aid in the prediction of factor for successful oral antiviral treatment in hepatitis C.

BACKGROUND: It has been demonstrated that there may be a relationship between liver fibrosis and serum biomarkers. The aim of this study was to investigate pre- and postoral antiviral therapy levels of these biomarkers and their relationship with other fibrotic parameters in hepatitis C virus (HCV) patients. METHODS: The study group comprised HCV patients who were treated with oral antiviral regimens. Prior to, and 8 months after the treatment, serum biomarkers, including transforming growth factor-ß (TGF-ß), chitinase-3-like protein 1 (YKL-40), collagen type IV, matrix metalloproteinases (MMPs) and hyaluronic acid levels, were examined and fibrosis-4 (Fib-4) and aspartate aminotransferase to platelet ratio index (APRI) scores were calculated at the same times. RESULTS: In total, 45 HCV patients (aged between 27 and 86 years) participated. Of these 20 (44.4%) were cirrhotic and 25 (55.6%) were noncirrhotic. The concentrations of YKL-40 (P = 0.01) and TGF-ß (P = 0.032) after treatment were significantly higher than the pretreatment values, whereas hyaluronic acid concentrations decreased after treatment (P = 0.001). Noncirrhotic patients had significantly higher (P = 0.03) YKL-40 levels prior to therapy compared to cirrhotic patients. Median MMP-2 concentrations were higher in men than in women (P = 0.001). Prior to treatment, TGF-ß, YKL-40 and collagen type IV levels were negatively correlated with Fib-4 scores, whereas only TGF-ß and YKL-40 concentrations were negatively correlated with APRI scores. CONCLUSION: YKL-40, TGF ß and hyaluronic acid may be markers for fibrotic change during oral therapy for HCV. In particular, TGF ß concentrations correlated with fibrotic indices. However, these results should be confirmed and validated by further research.

Serum irisin level, insulin resistance, and lipid profiles in patients with hidradenitis suppurativa: a case-control study

Abstract Background: Hidradenitis suppurativa is a chronic inflammatory skin disease of terminal follicular acroinfundibulum. Objectives: This study aimed to evaluate serum irisin, plasma glucose, insulin, and lipid levels in hidradenitis suppurativa, and elucidate possible associations with disease activity, inflammatory, or metabolic parameters. Methods: This case-control study included 37 patients (M/F: 9/28) and 37 sex-, age- and body mass index -matched healthy controls (M/F: 11/26). Demographic data, Hurley stage of disease, fasting glucose, insulin, total cholesterol, high density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, C-reactive protein levels, erythrocyte sedimentation rate, hematologic parameters, and serum irisin were assessed. Results: The hidradenitis suppurativa group had significantly higher waist circumference than controls (p < 0.001). Insulin resistance, defined as a homeostatic model assessment for insulin resistance value greater than 2.5, was observed in 45.9% of patients and 8.1% of controls (p = 0.003), whereas metabolic syndrome was observed in 32.4% of patients and 5.4% of controls (p < 0.001). Furthermore, plasma triglycerids, glucose, and insulin levels were significantly higher in the hidradenitis suppurativa (p = 0.013, p = 0.001, and p = 0.004), respectively. Mean irisin level was insignificantly higher in the hidradenitis suppurativa group (37.4 ± 32.6) than in controls (26.2 ± 24.7, p = 0.217). Study limitation: Physical activity and the exercise levels of participants were not documented. Conclusion: This study indicates that hidradenitis suppurativa patients have higher serum irisin, fasting plasma glucose, insulin, and triglycerides levels than healthy controls. Thus, the authors suggest that hidradenitis suppurativa patients should be evaluated for insulin resistance and metabolic syndrome, and monitored accordingly.

Liver and pancreas: 'Castor and Pollux' regarding the relationship between hepatic steatosis and pancreas exocrine insufficiency.

BACKGROUND: Pancreatic exocrine insufficiency (PEI) is found in 30-50% of diabetes mellitus (DM). Insulin resistance is triggering factor in both DM and nonalcoholic fatty liver disease (NAFLD). Therefore, we aimed to investigate frequency of PEI in NAFLD, and relationship of fecal pancreatic elastase (PE) levels with liver histology and pancreatic fat. METHODS: Ninety-seven biopsy proven NAFLD patients and 50 controls were enrolled. Pancreas exocrine functions were measured by PE. Magnetic resonance imaging-estimated proton density fat fraction (MRI-PDFF) was used to quantify fat. RESULTS: NAFLD patients had significantly lower PE levels than controls (297 [204-517] vs. 500 [298-678] µg/g, p < 0.01). PEI (PE < 200 µg/g) ratio of NAFLD patients (22.7%, n = 22) was higher than PEI ratio of controls (6%, n = 3) (p = 0.011). Among diabetic (n = 35) NAFLD patients, 9 (25.7%) exhibited PEI, compared to 13 (21%) of non-diabetics. There was no significant difference in patients with and without DM in terms of PEI (p = 0.592). Among NASH (n = 68) patients 16 (23.5%) exhibited PEI, compared to (20.7%) of non-NASH (p = 0.76). Multiple analysis revealed NAFLD as a predictor of PEI independent of age, sex and DM (OR = 4.892, p = 0,021). Mean pancreas MRI-PDFF was significantly higher in diabetics (13.7% ± 3.6% vs. 8.7% ± 5.1%, p = 0.001). There was no significant pancreas MRI-PDFF difference between NASH and non-NASH (P = 0.95). Mean pancreas MRI-PDFF was significantly higher in patients with PEI (13.7% ± 3.4% vs. 8.9% ± 5.2%, P < 0.01). CONCLUSION: This is the first study demonstrating the high frequency of PEI in NAFLD independent of DM. Moreover, increasing pancreatic steatosis appears to be associated with higher frequency of PEI in NAFLD.

The Effect of Different Blood Drawing Methods on Hemolysis and Test Results from Intravenous Catheters Used in Emergency Departments.

BACKGROUND: Hemolysis is frequently reported in samples sent from emergency departments. In our study we aimed to compare the influence of invitro hemolysis on test results and hemolysis ratios of different blood drawing techniques (aspiration method and vacuum filling technique) used to draw blood from intravenous (IV) catheters in Emergency Department. Two techniques (aspiration vs. vacuum filling) used to draw blood into three different tubes (Sarstedt S-Monovette® 4.9 mL Serum Gel tube, BD 5 mL Vacutainer® Rapid Serum Tube (RST), and 5 mL Vacutainer® SST™II tube) and evaluated the effect of the hemolysis index of the sera on the tests analyzed. METHODS: In the emergency department blood was drawn from 128 consecutive patients into Sarstedt S-Monovette® 4.9 mL Serum Gel tubes using aspiration technique and also into BD 5 mL Vacutainer® Rapid Serum Tubes (RST) and 5 mL Vacutainer® SST™II tubes using vacuum filling technique. All the tests requested from the patients were analyzed on all tubes and the hemolysis index of all the tubes were also evaluated. RESULTS: As a result, the percentage of hemolysis encountered in S-Monovette® vs. SST and S-Monovette® vs. RST was 4.41% vs. 14.71% and 0% vs. 18.97%, respectively (p < 0.001, p < 0.001). In addition to this, the mean values of the test results for each assay in S-Monovette® tubes showed a significant difference when compared to RST and SST (p < 0.01). CKMB and LDH test results found in the tubes filled using the aspiration techniques (S-Monovette®) were statistically significantly lower than the results gathered from the tubes filled using vacuum filling technique (Vacutainer® RST and Vacutainer® SST) (p < 0.001). CONCLUSIONS: The test results and HI taken from the aspiration method seemed to be more reliable despite the presence of hemolysis.

Salivary α-amylase levels in vertigo: Can it be an autonomic dysfunction?

We aim to demonstrate possible autonomic dysfunction based on salivary α-amylase measurements during and after the vertigo attacks associated with Ménière disease (MD) and benign paroxysmal positional vertigo (BPPV). Patients admitted to the emergency room with a diagnosis of vertigo attacks caused by either MD (n = 15) or BPPV (n = 9) constituted the study groups. The control group (n = 10) consisted of volunteer patients admitted to the emergency department with minor soft-tissue trauma. The first saliva samples were obtained immediately during the attacks and the second and third samples were obtained on the third and fifteenth days of the attack, respectively. In the controls, the first sample was obtained after admission to the hospital and the second sample was obtained on the third day. Salivary α-amylase levels were evaluated. The difference between salivary α-amylase levels in patients with MD and BPPV was not significant. The amylase value measured early after the BPPV attack was significantly lower than that of the controls (p = 0.008). Although not significant, an undulating pattern of salivary α-amylase levels was observed with both diseases. An autonomic imbalance could be partly demonstrated by salivary α-amylase measurement early after the attack in patients with BPPV. Therefore, amylase may be a promising marker that is worth further investigation.

The effects of physical therapeutic agents on serum levels of stress hormones in patients with osteoarthritis.

To investigate the effects of physical agents on the levels of stress hormones in patients with osteoarthritis (OA).Transcutaneous electrical nerve stimulation, hot packs, and therapeutic ultrasound were applied to the lumbar region and knees of patients with OA. Blood samples were taken for the measurement of the serum levels of glucose, insulin (INS), growth hormone (GH), prolactin (PRL), cortisol (COR), and plasma adrenocorticotropic hormone (ACTH) immediately before and after the 1st session, to investigate the acute effects of those physical agents on the endocrine system. The hormone levels were also measured every 5 sessions in a total of 10 sessions. The treatment response was also evaluated by using the visual analogue scale (VAS), Roland Morris Disability Questionnaire (RMDQ), and Western Ontario and McMaster Universities Arthritis Index (WOMAC) throughout the therapy period.After the 1st session, there was a decrease in INS levels and a mild decrease in PRL levels (P = 0.001 and P < 0.05, respectively). Throughout the 10-session therapy period, the INS levels increased, whereas the ACTH and COR levels decreased (P < 0.05 for all). The VAS-spine, RMDQ, VAS-knee, and WOMAC scores decreased (P = 0.001 for VAS-spine and P < 0.001 for all others). A positive correlation was detected between the changes in serum COR and WOMAC-pain score (P < 0.05).Although the combination therapy caused changes in INS level accompanied with steady glucose levels, the application of physical agents did not adversely affect the hormone levels. The decrease in ACTH and COR levels may be attributed to the analgesic effect of agents and may be an indicator of patient comfort through a central action.

Effect of manual lymph drainage on removal of blood lactate after submaximal exercise.

[Purpose] It has been well-established that exercise-induced muscle damage occurs following intense exercise. Massage is commonly used to manage muscle damage resulting from exercise. However the effect of massage after exercise is still not clear. The purpose of this study was to examine the effect of manual lymph drainage on muscle damage and on the removal of blood lactate following submaximal exercise (SE), as part of a solution to the challenging problem in sports medicine of muscular recovery after exercise. [Subjects and Methods] Eighteen healthy male students, with moderate exercise training, were randomly assigned to either receive manual lymph drainage (MLD) or serve as controls. Both groups were subjected to a graded exercise test, performed on a treadmill ergometer, to determine each subject's individual anaerobic threshold (IAT). Seven days later, all subjects were made to run for 30 minutes on the same treadmill ergometer, at a running speed equivalent to the IAT. One group received MLD treatment, while the control subjects received no treatment. [Results] Following an increase immediately after exercise, lactic acid (LA) and lactate dehydrogenase (LDH) serum levels dropped rapidly and significantly at the end of MLD application and two hours after SE in the subjects receiving MLD. The course of creatine kinase (CK) and myoglobin levels was comparable, and with myoglobin showing a significant difference at 2 h after SE, and CK at 24 h after SE. [Conclusion] Manual lymph drainage after SE correlated with a more rapid fall in LA and of the muscular enzymes of LDH, CK and myoglobin, and may have resulted in an improvement in the regenerative processes elicted by structural damage to the muscle cells.

Effect of epidural levobupivacaine and levobupivacaine with fentanyl on stress response and postoperative analgesia after total knee replacement.

BACKGROUND: Providing sufficient and convenient analgesia is crucial during the postoperative period after totalknee replacement (TKR) to enhance patient mobility and reduce stress response to surgery. The scope of this study is to compare the effects of levobupivacaine and levobupivacaine plus fentanyl on stress response and analgesic efficiency after TKR. METHOD: In this study, 40 ASA I - II patients scheduled to undergo TKR were subjected to combined spinal epidural anesthesia (CSEA) injecting of 15 mg levobupivacaine and randomly assigned to receive either levobupivacaine 0.125% (Group L) or levobupivacaine 0.125% plus fentanyl 4 µg ml-1 (Group F) during postoperative period via the epidural route. Patient controlled epidural analgesia (PCEA) was offered for 24 hours. Venous blood samples were assayed for adrenocorticotropic hormone (ACTH), cortisol and prolactin levels before surgery and after analgesia administration. Analgesia was assessed using a visual analogue scale (VAS) at rest (VASR) and during movement (VASM). RESULTS: There was no statistically significant difference between the groups in terms of total doses, bolus requests, bolus delivered and side effects (p > 0.05). The ACTH, cortisol and prolactin levels increased following the surgery and decreased during PCA infusion in both groups where the decline in Group F was significant (p < 0.05) at 24 hours after the analgesic treatment and 48 hours after the surgery. CONCLUSION: We have demonstrated that infusion of levobupivacaine (0.125%) in combination with fentanyl (4 µg ml-1) using PCEA suppressed stress response to surgery significantly and provided better pain relief than levobupivacaine (0.125%) alone after TKR.

Effect of beta-glucan in lung damage secondary to experimental obstructive jaundice.

BACKGROUND/AIMS: This study aimed at investigating the protective effects of beta-glucans on the lungs in obstructive jaundice. METHODS: In total, five groups -Sham (1), control (2) and treatment groups (3,4,5)- were established; each comprising randomly selected seven Wistar Albino rats. Beta-glucan was given after choleduct ligation in Group 3 while it was given before and after the choleduct ligation in Group 4. As pre-treatment beta-glucan was given before ligation in Group 5. Beta-glucan was administered in a single dose of 50 mg/kg/day by gavage for a ten-day period. Superoxide dismutase, and myeloperoxidase levels in serum; malondialdehyde, lipid hydroxyperoxidase and glutathione levels in lung tissue; lactate dehydrogenase levels in bronchoalveolar lavage fluid were measured. RESULTS: The blood polymorphonuclear leukocytes level was highest in the control group and lower in the sham and treatment groups. Serum superoxide dismutase and tissue glutathione values were significantly higher in Groups 3 and 4 (p≤0.04) whilst Groups 3 and 4 did not differ from each other. In Groups 3 and 4 malondialdehyde, lipid hydroxyperoxidase, and myeloperoxidase values were significantly lower. However, Groups 3 and 4 did not differ for malondialdehyde or lipid hydroxyperoxidase values. Lactate dehydrogenase level in the bronchoalveolar lavage fluid was significantly lower in all of the treatment groups (Groups 3,4,5) (p≤0.008). When compared to the control group, it was observed that lung damage was much more limited in the treatment groups (p<0.001). CONCLUSION: This study suggests that beta-glucan exhibits protective effect in pulmonary tissue against oxidative damage in obstructive jaundice.

BACKGROUND: Beta-glucans are known as macrophage stimulators and antioxidants. This study aimed to investigate the effects of beta-glucans on oxidative damage to the liver during obstructive jaundice. METHODS: Sham, control and treatment groups (7 Wistar Albino rats in each) were designed. In the treatment group, beta-glucan was given through gavages for 10 days after bile duct ligation. All groups were sacrificed on the 11th day. Liver function tests, superoxide dismutase (SOD), myeloperoxidase (MPO), malondialdehyde (MDA), lipid peroxide (LPO), glutathione (GSH), and histopathological examination of the liver were investigated. RESULTS: In the treatment group, the levels of alanine and aspartate aminotransferases (AST, ALT), gamma glutamyl transpeptidase (GGT), lactate dehydrogenase (LDH), total and direct bilirubin, MPO in the serum, and the levels of MDA and LPO in the liver tissue were significantly lower when compared with the control group. Moreover, SOD and GSH levels were relevantly high in the treatment group. Histopathological examination of the liver revealed less damage in the treatment group. CONCLUSION: These results show that beta-glucan induced the phagocytic and anti-oxidative effects and also reduced the liver damage and oxidative stress in obstructive jaundice. Advanced studies are required for the clinical use of beta-glucan in obstructive jaundice.

Reliability of the 34ßE12, keratin 5/6, p63, bcl-2, and AMACR in the diagnosis of prostate carcinoma.

OBJECTIVE: In this study, we aimed to investigate which basal cell marker should be used with α-methylacyl coenzyme A racemase (AMACR) to increase diagnostic accuracy in the diagnosis of prostate carcinoma. MATERIALS AND METHODS: A total of 98 cases of prostate biopsy, comprising 65 cases with prostate adenocarcinoma and 33 cases without adenocarcinoma, were included in this study. Prostate-specific antigen (PSA) serum levels before biopsies were obtained. The number of cores with malignant glands and Gleason scores for each case were determined. Paraffin sections were stained immunohistochemically with 34ßE12, keratin 5/6, p63, bcl-2, and AMACR. RESULTS: According to staining pattern, extensiveness, and intensity of basal cell markers in benign glands, 34ßE12 gave the best results. As negative markers for prostate adenocarcinoma, the best markers were p63 and 34ßE12. According to the AUC values in ROC curves for both extensiveness and intensity, the arrangement from the best to the worst was 34ßE12, p63, bcl-2, and keratin 5/6. The 34ßE12 had the best sensitivity and specificity values (95% and 98%, respectively). Staining extensiveness and intensity of keratin 5/6 in malignant glands, and those of bcl-2 in benign glands had statistically significant positive correlation with serum PSA levels. Even though AMACR is a negative marker for benignity, some of the benign glands also had positive immune reaction with AMACR. However, AMACR positivity was usually focal and weak. Nevertheless, intensively stained subjects were also present. No correlation was present between AMACR and basal cell markers. CONCLUSIONS: As a result, we suggest that keratin 5/6 and bcl-2 should not be used to identify benign glands in prostate biopsy since they show high positivity in malignant glands and high negativity in benign glands. 34ßE12 should be the first choice as a basal cell marker. p63 can be used together with 34ßE12, but it may not give additional diagnostic information. When we evaluated the correlation of basal cell markers, we did not find any complementary staining results among basal cell markers. Our study showed that 34ßE12 is the most appropriate negative marker to combine with AMACR as a positive marker for the diagnosis of prostate adenocarcinoma.
