OBJECTIVE: Globally, stroke is the leading cause of disability and death. With the use of thrombolytic therapy, reperfusion injury, and its consequences came to the fore. We aimed to find out how anzer propolis, which can only be obtained in Turkey's Eastern Black Sea region, affected ischemia-reperfusion injury using biochemical and histological techniques. MATERIALS AND METHODS: 32 female Wistar albino rats were divided into 4 groups, including a control group. Three of the groups underwent 30 minutes of induced ischemia via clamping of the common carotid artery, followed by ischemia-reperfusion injury through the release of the clamp. One group received no treatment, another received oral administration of 100 mg/kg of anzer propolis one hour before surgery, and the third group received oral administration of 40 mg/kg of acetylsalicylic acid just before surgery. Histopathological examination assessed apoptosis and tissue necrosis, while serum and brain tissue were evaluated for levels of nerve growth factor (NGF), Interlokin 1ß (IL-1ß), Interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-a), total antioxidant capacity (TAS), and total oxidant capacity (TOS). RESULTS: Anzer propolis and acetylsalicylic acid significantly reduced hyperemia in vessels, vacuolization in neurons, glial cell infiltration, and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) positivity. The anzer propolis group had the highest NGF levels. The anzer propolis and acetylsalicylic acid groups had lower levels of TNF-a and IL-6 in the brain tissue than the ischemia-reperfusion group, while TAS levels were higher. CONCLUSIONS: The findings obtained in this study suggest that anzer propolis has a neuroprotective effect against ischemia-reperfusion injury and will have beneficial effects on neurodegeneration. We believe our findings will contribute to the clinical treatment of ischemia-reperfusion injury. [ABSTRACT FROM AUTHOR]

Introduction: Epilepsy is a disease that affects a significant proportion of the female population worldwide. The management of anti-seizure medications during pregnancy and the potential adverse outcomes to both the mother and fetus represent a significant challenge. This retrospective study aimed to evaluate the impact of anti-seizure medications during pregnancy by comparing maternal and fetal outcomes between pregnant women with and without epilepsy., Methods: A total of 242 participants were analysed, including 112 with epilepsy and 130 healthy pregnant controls. Maternal age, medical history, seizure characteristics, use of anti-seizure medications, and pregnancy history were recorded. Maternal and fetal complications, delivery modes, and perinatal outcomes were evaluated., Results: A total of 242 patients, including 112 (46.3 %) pregnant women with epilepsy and 130 (53.7 %) healthy pregnant women, were included in the study. Among pregnant patients with epilepsy, 4 (3.5 %) did not use anti-seizure medications, 79 (70.5 %) received monotherapy, and 29 (25.8 %) received polytherapy. The rates of pregnancy termination, spontaneous abortion, and maternal and fetal complications were significantly higher in pregnant women with epilepsy (p = 0.045, p = 0.045, p < 0.001, and p = 0.016, respectively). Folic acid use, planned pregnancy rate and postpartum breastfeeding rate were all statistically lower in pregnant women with epilepsy (p < 0.001, p < 0.001, p < 0.001, respectively). The rates of intensive care unit stay, infants with birth weight less than 2500 g, congenital malformations, and preterm births were significantly higher in babies born to pregnant women with epilepsy (p < 0.001, p = 0.047, p = 0.003, and p = 0.051, respectively). Gestational diabetes mellitus was observed in 4 (13.8 %) and congenital malformations in 4 (14.3 %) of the pregnant women with epilepsy who received polytherapy, and in both cases these rates were statistically higher than those of pregnant women with epilepsy who received monotherapy (p = 0.048 and p = 0.004, respectively)., Discussion: This study demonstrated that pregnancies among women affected by epilepsy have significantly higher rates of maternal and fetal complications, spontaneous abortions, and premature births. Polytherapy with anti-seizure medications is associated with an increased risk of gestational diabetes and congenital anomalies. Notably, folic acid use, planned pregnancy, and postpartum breastfeeding were less common in patients with epilepsy. The most commonly prescribed anti-seizure medications were levetiracetam and lamotrigine. Caesarean section is a common mode of delivery in pregnancies of mothers with epilepsy., Conclusion: These results suggest that epilepsy increases both maternal and fetal complications during pregnancy. Furthermore, the use of anti-seizure medications appears to have a significant impact on pregnancy outcomes. Our findings highlight the need for comprehensive management strategies and informed decision making to reduce risks and optimise maternal and fetal outcomes among women with epilepsy., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Aim: The objective of the study was to assess the impact of ozone (O 3 ) and trimetazidine on the intestines following ischemia-reperfusion (I/R) injury through the investigation of endoplasmic reticulum stress., Methods: Forty Sprague Dawley rats were separated into five groups. The groups were named as follows: control, O 3 , I/R, I/R + trimetazidine (TMZ), and I/R + O 3 . The control group had laparotomy and exploration of the superior mesenteric artery (SMA) only. Furthermore, alongside laparotomy and SMA exploration, an intraperitoneal (i.p.) administration of a 0.7 mg/kg ozone-oxygen (O 3 -O 2 ) combination was given to the O 3 group. In the experimental groups, the SMA was blocked with the silk suture ligation technique for a duration of 1 h and then restored to normal blood flow for another hour. In the I/R + O 3 group, ozone was delivered i.p. at a dosage of 0.7 mg/kg, 30 min after ischemia. In the I/R + TMZ group, a dose of 20 mg/kg/day of trimetazidine was administered orally via gavage for a duration of 7 days, beginning 1 week prior to the induction of ischemia. Intestinal tissues were taken to assess indicators of intestinal mucosal injury and oxidative stress., Results: The level of the lipid peroxidation marker malondialdehyde (MDA) was significantly reduced in the experimental groups as compared to the I/R group ( p < 0.05). The experimental groups had considerably greater levels of glutathione (GSH), which reflects antioxidant capacity, compared to the I/R group ( p < 0.05). Nevertheless, the concentration of GSH was observed to be increased in the I/R + O 3 group in comparison to the I/R + TMZ group ( p < 0.05). The histopathological damage score showed a substantial decrease in the experimental groups as compared to the I/R group ( p < 0.05). The I/R + O 3 group had the lowest injury score. The experimental groups exhibited significantly reduced positivity of the endoplasmic reticulum (ER) stress markers C/EBP homologous protein (CHOP) and glucose-regulated protein (GRP)-78 compared to the I/R group ( p < 0.05)., Conclusions: The findings provide evidence for the potential advantages of utilizing ozone therapy in the treatment of intestinal ischemia-reperfusion injury. Additionally, they propose that ozone should be assessed in more extensive clinical trials in the future as a therapeutic agent that can disrupt endoplasmic reticulum stress.

Background: Idiopathic trigeminal neuralgia (TN) cases encountered frequently in daily practice indicate significant gaps that still need to be illuminated in the etiopathogenesis. In this study, a novel TN animal model was developed by compressing the dorsal horn (DH) of the upper cervical spinal cord., Methods: Eighteen rabbits were equally divided into three groups, namely control (CG), sham (SG), and spinal cord compression (SCC) groups. External pressure was applied to the left side at the C3 level in the SCC group. Dorsal hemilaminectomy was performed in the SG, and the operative side was closed without compression. No procedure was implemented in the control group. Samples from the SC, TG, and ION were taken after seven days. For the histochemical staining, damage and axons with myelin were scored using Hematoxylin and Eosin and Toluidine Blue, respectively. Immunohistochemistry, nuclei, apoptotic index, astrocyte activity, microglial labeling, and CD11b were evaluated., Results: Mechanical allodynia was observed on the ipsilateral side in the SCC group. In addition, both the TG and ION were partially damaged from SC compression, which resulted in significant histopathological changes and increased the expression of all markers in both the SG and SCC groups compared to that in the CG. There was a notable increase in tissue damage, an increase in the number of apoptotic nuclei, an increase in the apoptotic index, an indication of astrocytic gliosis, and an upsurge in microglial cells. Significant increases were noted in the SG group, whereas more pronounced significant increases were observed in the SCC group. Transmission electron microscopy revealed myelin damage, mitochondrial disruption, and increased anchoring particles. Similar changes were observed to a lesser extent in the contralateral spinal cord., Conclusion: Ipsilateral trigeminal neuropathic pain was developed due to upper cervical SCC. The clinical finding is supported by immunohistochemical and ultrastructural changes. Thus, alterations in the DH due to compression of the upper cervical region should be considered as a potential cause of idiopathic TN., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: Over the past decade, the prevalence of Multiple Sclerosis (MS) has increased in Turkey. However, the prevalence of MS in Middle Anatolia, specifically Afyonkarahisar, remains unknown. Additionally, the potential link between economic status and MS has not yet been explored in Turkey., Methods: A stratified sampling method was employed to select samples from the population residing in Afyonkarahisar City Center, taking into account demographic factors such as income level, sex, and age. The sample size was calculated using the formula N = p.q.Z α 2 /d 2 , where an average prevalence rate of 70/100,000 was considered based on previous studies. The minimum sample size was 29,858. Considering incomplete, inaccurate, and low-reliability data, data were collected from 30,500 individuals and 30,408 individuals were evaluated., Results: The prevalence of Multiple Sclerosis in the center of Afyonkarahisar was 105.2 per 100,000 individuals. Upon investigating the association between economic status and MS prevalence, the findings revealed rates of 193.6 per 100,000 in individuals with high income, contrasting with 80.2 per 100,000 in those with low income. Notably, a heightened prevalence of MS is evident among individuals with higher income levels., Conclusion: This study revealed a significantly elevated prevalence of MS in Afyonkarahisar, the highest in Turkey. The inverse correlation between the prevalence of MS and socioeconomic status is intriguing. Possible reasons for the high prevalence include the relatively new and specific geologic and environmental conditions in the area., Competing Interests: Declaration of Competing Interest No conflict of interest exists among the authors of this article, (Copyright © 2023 Elsevier B.V.

Background: Population-based studies examining the prevalence of trigeminal neuralgia (TN) and persistent idiopathic facial pain (PIFP) are rare, and data on TN prevalence in Türkiye are very limited, with the prevalence of PIFP being unknown. This study aimed to determine the prevalence of TN and PIFP in Türkiye., Materials and Methods: This population-based epidemiological study has a cross-sectional and descriptive design, and it was carried out in Afyonkarahisar, Türkiye. Participants aged 18 years and older were screened by using a self-assessment form to determine potential patients with TN or PIFP., Results: A total of 19,237 individuals were included in this study, of which 17,223 responded to the survey questions. TN was diagnosed in 17 individuals, and the prevalence of TN was calculated as 98.5 per 100,000. PIFP was diagnosed in 35 patients, and the prevalence of PIFP was calculated as 202 per 100,000. The mean age of the patients with TN was 54.29 ± 12.98 years, the mean age of patients with PIFP was 49.80 ± 16.10 years, and the female-to-male ratio was 1.13/1 for TN and 2.18/1 for PIFP., Conclusion: The prevalence of PIFP in Türkiye has been reported for the first time by this study. Additionally, a much higher prevalence of TN was found when compared to previous study., (© 2024 S. Karger AG, Basel.)

Objective: Intragastric balloon placement is an effective method for weight reduction. The aim of this study was to evaluate the efficacy of combining liraglutide with intragastric balloon., Methods: Initially, demographic data of patients such as age, gender, comorbid diseases, adverse events, initial weight, height, body mass index, percent body fat, and waist-hip ratio were collected. Weight, body mass index, percent body fat, and waist-hip ratio were measured in the second, third, fourth, fifth, and sixth months. Then, intragastric balloon was removed and liraglutide was stopped., Results: A total of 50 patients were included in the study, of whom 28 (56%) were in Group A (intragastric balloon) and 22 (44%) were in Group B (plus liraglutide). Weight change at the time of balloon removal was higher in Group B [median weight change 13.8 (7.8 min to 16.8 max) versus 7.9 (4.8 min to 11.8 max); p<0.01]. When the weight, percent body fat, body mass index, and waist-hip ratio changes were compared according to gender, no significant difference was observed in the groups. Comorbid diseases were hypertension in 7 patients (4 in Group A and 3 in Group B) and diabetes in 9 patients (5 in Group A and 4 in Group B). No statistical significance was found., Conclusion: Liraglutide has benefits in terms of weight, percent body fat, and body mass index reduction when administered with intragastric balloon.

One group received no treatment, another received oral administration of 100 mg/kg of anzer propolis one hour before surgery, and the third group received oral administration of 40 mg/kg of acetylsalicylic acid just before surgery. Histopathological examination assessed apoptosis and tissue necrosis, while serum and brain tissue were evaluated for levels of nerve growth factor (NGF), Interlokin 1β (IL-1β), Interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), total antioxidant capacity (TAS), and total oxidant capacity (TOS)., Results: Anzer propolis and acetylsalicylic acid significantly reduced hyperemia in vessels, vacuolization in neurons, glial cell infiltration, and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) positivity. The anzer propolis group had the highest NGF levels. The anzer propolis and acetylsalicylic acid groups had lower levels of TNF-a and IL-6 in the brain tissue than the ischemia-reperfusion group, while TAS levels were higher., Conclusions: The findings obtained in this study suggest that anzer propolis has a neuroprotective effect against ischemia-reperfusion injury and will have beneficial effects on neurodegeneration. We believe our findings will contribute to the clinical treatment of ischemia-reperfusion injury.

Although radiotherapy is widely employed in the treatment of various malignancies in oncology patients, its use is limited by the toxic effects it causes in surrounding tissues, including the gastrointestinal system. Korean Red Ginseng (KRG) is a traditional drug reported to possess antioxidant and restorative properties in various studies. The purpose of the present study was to investigate the protective effects of KRG against radiation-associated small intestinal damage. Twenty-four male Sprague Dawley rats were randomly assigned into three groups. No procedure was performed on Group 1 (control) during the experiment, while Group 2 (x-irradiation) was exposed to radiation only. Group 3 (x-irradiation + ginseng) received ginseng via the intraperitoneal route for a week prior to x-irradiation. The rats were killed 24 h after radiation. Small intestinal tissues were evaluated using histochemical and biochemical methods. An increase in malondialdehyde (MDA) levels and a decrease in glutathione (GSH) were observed in the x-irradiation group compared to the control group. KRG caused a decrease in MDA and caspase-3 activity and an increase in GSH. Our findings show that it can prevent damage and apoptotic cell death caused by x-irradiation in intestinal tissue and can therefore play a protective role against intestinal injury in patients receiving radiotherapy., (© 2023.

Introduction: It is known that there is a relationship between severe exacerbations of chronic obstructive pulmonary disease(COPD) requiring hospitalization with loss of forced expiratory volume in one second (FEV1), impaired quality of life, and increased mortality. The aim of this study was to investigate factors [health-related quality of life with COPD Assessment Test (CAT), physical activity, FEV1, PaO2] affecting the time to first exacerbation (TTFE) after discharge in patients hospitalized with exacerbation., Materials and Methods: Seventy-five patients who were hospitalized due to COPD acute exacerbation were included in the study and were prospectively monitored. First exacerbation after discharge was recorded. During the first three days of hospitalization, patients were fitted with a pedometer on any of these days; 24-hour step counts were recorded and CAT was administered through face-to-face interviews. Data on age, sex, PaO2, FEV1, and comorbidities were recorded. The median value of the CAT scores of the participants were taken as the cut-off point. High scores were considered as an indicator of poor quality of life. Cox regression models were created for multivariate analyses and hazard ratios (HR) with 95% confidence interval (95% CI) provided., Result: There was a statistically significant relationship between the TTFE and CAT score (p= 0.001), FEV1 (pred %) (p= 0.02) and PaO2 (p= 0.02). No statistically significant relationship was found between TTFE and the number of steps used as an indicator of physical activity (p= 0.3). In multivariate analysis, age and sex adjusted CAT and PaO2 significantly affected the TTFE (HR= 2.06 CI 95%= 1.17-3.65 and HR= 5.50 CI 95%= 2.09-14.49, respectively) while adjusted FEV1 (pred %) was not significantly affected the TTFE (HR= 1.54 CI 95%= 0.88-2.70)., Conclusions: The results of this study suggest that using CAT may be an easy-to-apply and practical tool to help identify patients with an increased risk of exacerbation. No significant correlation was found with the daily number of steps, which is an easily measurable indicator of physical activity.

Objectives: Carbon tetrachloride (CCl 4 ), employed in various industrial fields, can cause acute damage in renal tissues. This study investigated the therapeutic effect of the TNF-alpha inhibitor Infliximab on TGF-ß and apoptosis caused by acute kidney image induced by CCl 4 ., Methods: Twenty-four male Sprague-Dawley rats were assigned into control, CCl 4 , and CCl 4 + Infliximab groups. The control group received an isotonic saline solution, and the CCl 4 group 2 mL/kg CCl 4 intraperitoneally (i.p). The CCl 4 + Infliximab group was given 7 mg/kg Infliximab 24 hours after administration of 2 mL/kg CCl 4 . Kidney tissues were removed at the end of the experiment and subjected to histopathological and biochemical analysis., Results: The application of CCl 4 led to tubular necrosis, inflammation, vascular congestion, and increased Serum BUN and creatinine values. An increase in caspase-3 activity also occurred in the CCl 4 group. However, Infliximab exhibited an ameliorating effect on kidney injury by causing a decrease in the number of apoptotic cells. Tissue ADA and TGF-ß values of the CCL4 group were significantly higher than the values of the control group ( p = .001, p < .001 respectively) and CCL 4 + Inf group ( p = .004, p = .015, respectively)., Conclusions: This study shows that Infliximab ameliorates nephrotoxicity by reducing lipid peroxidation, oxidative stress, and apoptosis in acute kidney damage developing in association with CCl 4 administration. These findings are promising in terms of the ameliorating role of TNF-alpha inhibitors in acute kidney injury.

Background: The coronavirus disease-19 (COVID-19) pandemic has changed the course of diseases that require emergency surgery., Objective: To evaluate the effect of the COVID-19 pandemic on colorectal cancer disease stage., Design and Setting: Retrospective analysis in the city of Rize, Turkey., Methods: This was a comparative analysis on two groups of patients with various symptoms who underwent surgical colorectal cancer treatment. Group 1 comprised patients operated between March 11, 2019, and December 31, 2019; while group 2 comprised patients at the same time of the year during the COVID-19 pandemic., Results: Groups 1 and 2 included 56 and 48 patients, respectively. The rate of presentation to the emergency service was higher in Group 2 (P < 0.02). The stage of the pathological lymph nodes and the rate of liver metastasis was higher in Group 2 (P < 0.004 and P < 0.041, respectively). The disease stage was found to be more advanced in Group 2 (P < 0.005). The rate of postoperative complications was higher in Group 2 (P < 0.014)., Conclusion: The presentation of patients with suspicious findings to the hospital was delayed, due both to the fear of catching COVID-19 and to the pandemic precautions that were proposed and implemented by healthcare authorities worldwide. Among the patients who presented to the hospital with emergency complaints and in whom colorectal cancer was detected, their disease was at a more advanced stage and thus a higher number of emergency oncological surgical procedures were performed on those patients.

Objective The aim of this study was to determine the factors and rates of secondary bacterial infections developed in patients after the diagnosis of COVID-19 and antimicrobial susceptibility to guide the empirical treatment and contribute to epidemiological data. Materials and Methods In our study, 1,055 patients diagnosed with COVID-19, hospitalized at Recep Tayyip Erdoğan University Training and Research Hospital, Rize, between the dates March 24, 2020 and December 31, 2020, were recruited. The diagnoses of all patients were confirmed by positive SARS-CoV-2 polymerase chain reaction (PCR) tests. In addition, the blood and respiratory tract cultures of the patients recruited in the study were analyzed retrospectively. Results Ninety-two (8.7%) patients were found to have microbiologically proven respiratory or circulatory tract infections via microbial culture results. Respiratory tract infections were detected as monomicrobial in 44 patients and as polymicrobial in 17 patients, among a total of 61 patients. In addition, 59 (64.1%) patients were male patients, and 33 (35.9%) were female patients. Among the microorganisms grown in blood cultures,  coagulase - negative staphylococci  with a percentage of 31% and  Acinetobacter baumannii  with a percentage of 27.5% were prominent. In respiratory tract cultures, A. baumannii constitutes the majority with a percentage of 33.3%, followed by  Staphylococcus aureus  and  Klebsiella pneumoniae  with a percentage of 9.5% each. The most resistant bacteria were  A. baumannii , resistant to all antibiotics other than colistin. Conclusion Secondary bacterial infection rates in patients with COVID-19 are lower than influenza pandemic. However, the frequency of empirical antibiotics use seems relatively high., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2022, Bahceci et al.)

Purpose : Prolonged surgical procedures and some clinical conditions such as surgeries of thoracoabdominal aorta, mesenteric ischemia, cardiopulmonary bypass, strangulated hernias and neonatal necrotizing enterocolitis may cause decreased perfusion and injury of relevant organs and tissues. After reperfusion, injuries may get worse, leading to ischemia-reperfusion (I/R) injury. Reperfusion following arterial clamping allows oxygen to ischemic tissues and produce injury by multiple mechanisms, including neutrophilic infiltration, intracellular adhesion molecules, and generation of reactive oxygen radicals. In this study with the analysis of SOD, MDA and Caspase-3 levels, we aimed to investigate the effect of topiramate on the outcome of I/R occured after abdominal aorta clamping on rats. Materials and Methods : Totaly 24 Sprague-Dawley male rats were randomly divided into three experimental groups; the control group ( n = 8), I/R ( n = 8) and I/R+ topiramate ( n = 8). Topiramate (100 mg/kg/day); 50 mg/kg (single dose) was administered intraperitoneally after being diluted with saline 5 days before I/R. Results : The intestinal tissue of the ischemia group displayed hemorrhage, Crypts of Lieberkuhn degeneration, ulceration, vascular congestion and edematous fields as a result of aortic occlusion. We also observed that MDA levels and Caspase-3 positivity increased and SOD levels decreased in the small intestine. However, topiramate administration decreased Crypts of Lieberkuhn degeneration, ulceration, vascular congestion and edematous fields, Caspase-3 positivity, and MDA levels. Conclusion : Our findings suggest that topiramate is effective against aortic occlusion-induced intestinal injury by reducing oxidative stress and apoptosis.

Objective: To determine the results of high-risk geriatric patients treated with percutaneous cholecystostomy (PC) for acute cholecystitis (AC)., Study Design: Observational study., Place and Duration of Study: Department of Interventional Radiology, Recep Tayyip Erdogan University Hospital, Rize, Turkey, from April 2015 to October 2020., Methodology: Seventy-four patients, who underwent PC with a diagnosis of AC, were divided into three groups according to their ages: 65-74 years as group I, 75-84 years as group II, and ≥85 years as group III. Groups were compared in terms of American Society of Anesthesiologists (ASA) score, Charlson Comorbidity Index (CCI), technical success, clinical success, complications, need for cholecystectomy, duration of hospital stay, 30 and 90 days mortality, catheter removal time, and recurrent cholecystitis after catheter insertion., Results: Technical success was 100% in all groups. Clinical success decreased with age. There was a positive correlation between the patients' ASA score and age (p <0.001). The duration of hospital stay increased with age (p = 0.049). ASA score was found to be an independent risk factor in predicting overall survival (HR: 4.748; 95% CI: 1.030-21.895; p = 0.046). The mean catheter removal time was the longest in group III, and there was a significant difference between the groups (p <0.001). A significant positive correlation was found between catheter removal time and CCI (p <0.001). There was no statistically significant difference between groups in terms of complications and recurrent cholecystitis.  Conclusion: PC can be considered as definitive treatment in advanced elderly patients and interval therapy in early old age. Key Words: Acute cholecystitis, Elderly, Percutaneous cholecystostomy.

Objective: To discriminate between malignant or benign axillary lymph nodes in breast cancer using MRI, PET-CT, and sentinel lymph node biopsy., Study Design: Observational study., Place and Duration of Study: Department of General Surgery, Recep Tayyip Erdogan University School of Medicine, from January 2014 to March 2019., Methodology: Sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) was carried out on 102 patients, who had locally advanced cases and had not previously received neoadjuvant therapy. Axillary lymph nodes pathology results were evaluated and compared with PET-CT and MRI findings., Results: PET-CT specificity was 93.18%, MRI specificity was 93.75%, and combined PET-CT and MRI specificity was 97.67%. PET-CT sensitivity was 81.03%, MRI sensitivity was 68.57%, and combined PET-CT and MRI sensitivity was 83.05%. For detecting the presence of axillary lymph node metastasis, there was a good correlation between histopathological results and the combined evaluation with PET-CT and MRI (kappa: 0.785, p <0.001). In combined PET-CT and MRI, short diamater mean values of lymph nodes in 10 patients, which could not detect lymph node metastases, were determined to be 5.2 ±0.9 mm., Conclusion: Combining PET-CT and MRI is superior to PET-CT or MRI imaging alone in distinguishing benign and malignant axillary lymph node; and contributes to deciding the approach to axillary lymph node surgery. Lymph node size is also important for this imaging method to determine benign and malignant nodes correctly. Key Words: Breast cancer, PET-CT, MRI, Sentinel lymph node biopsy, Axilla.

Background: The present study aims to observe the effects of ischemia-reperfusion (IR) on small intestines at a molecular level and to prospectively assess the potential preventive role of adalimumab (ADA) and antioxidants., Methods: A total of 24 male Sprague-Dawley rats were randomly divided into three groups-a control group, an IR group and an IR+ADA group., Results: Although there was no change in SOD levels in the small bowel tissue of the IR group, we observed increased malondialdehyde (MDA) levels and increased numerical density of caspase-3 and TNF-α positive enterocytes p=0.00 and p=0.00, respectively). We also observed that IR caused the degeneration of villus crypt structures., Conclusion: We found that ADA treatment reduced MDA levels and decreased the numerical density of caspase-3 and TNF-α positive enterocytes compared to the IR group (p=0.00; p=0.011; p=0.00, respectively). We conclude that ADA can be beneficial in preventing intestinal injury that arises from IR.

Background: The incidence of abdominal wall hematomas increased after the introduction of anticoagulant and antiplatelet drugs in clinical practice. These patients are usually old, and they have more than one comorbidity. Most spontaneous hematomas tend to limit itself and conservative treatment with close follow up is usually enough, but surgery is an option that should be decided critically. Unnecessary surgical interventions could worsen the situation. The present study aims to analyze the results of patients under anticoagulant/antiplatelet treatment and with spontaneous abdominal wall hematomas from surgeons' perspective., Methods: This is a retrospective study that the medical records of 43 patients who were under anticoagulant/antiplatelet therapy and consulted our general surgery clinic because of the spontaneous abdomen and abdominal wall hematoma between January-2016 and September-2018 were reviewed., Results: The findings showed that most of the cases were presented with abdominal pain. Thirty of these patients were female (69.7%). The mean age was 69.32 years. More than half of the patients (58.1%) were referred from the emergency department. All of the cases were under anticoagulant and antiplatelet treatment for several reasons. With presenting signs and symptoms and after evaluation of laboratory tests, computed tomography was performed to 30 patients (69.7%) as an initial test. USG and MRI were the other methods used. The most common diagnosis was rectus sheath hematoma (n=16; 37.2%) and followed by intestinal and colon wall, lumbar, psoas, pelvic and retroperitoneal hematoma in decreasing order. Among 43 patients, 39 patients (90.6%) followed with conservative treatment and two patients were treated with transcatheter arterial embolization. Two patients (4.6%) were died on day 1 and 11 after diagnosis. No surgery needed for all patients., Conclusion: Early recognition, hospitalization of risky patients, close follow-up of hemodynamic parameters, patients' response to conservative treatment and minimal invasive methods are key points. Conservative care is the choice of treatment, but surgery must always keep in mind in hemodynamic unstable patients.

Background: The population-based information on the prevalence of stroke from rural areas of Middle East countries including Turkey is unknown. Our aim is to evaluate the prevalence of stroke in those ⩾18 years in the Turkish population in a rural area of Istanbul., Methods: A cross-sectional door-to-door study was conducted in a rural area of Istanbul between 1 March and 30 March 2013. A research protocol recommended by World Health Organization for developing countries was used. Each screening teams consisted of one neurologist, one local nurse, and five surveyors. Teams were trained about the survey and questionnaire. The patients, who claimed to have suffered a stroke, were examined, and the diagnosis was confirmed by a neurologist on site. The findings and medical records were documented., Results: In total, 2906 people ⩾18 years were screened. 50 stroke cases were detected. 80% of those were found to have had an ischemic stroke, 14% of those were hemorrhagic cases, and 6% of those had an unclassified stroke type. The overall prevalence rate in those ⩾ 18 years was 1.7%. The male/female ratio was 0.92. Young (<45) stroke prevalence was found to be 0.6%., Conclusion: This study was the first of its kind to show the stroke prevalence among Turkish population ⩾ 18 years in a rural area of Istanbul. When compared to other studies which investigate people ⩾45 years from Turkey, the result (in the same age group) was moderate high. The male/female ratio was low compared to many other studies., Competing Interests: Declaration of conflicting interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Biliary pancreatitis (BP) constitutes 30-55% of all cases of acute pancreatitis. Laparoscopic cholecystectomy (LC) has become the gold standard for the surgical treatment of gallbladder disease. We aimed to compare and evaluate the relation between the timing of LC and the rates and reasons of conversion to open surgery (OS) after BP., Methods: Data were collected of patients who presented for the first time with acute BP and underwent LC. The patients were divided into two groups: early cholecystectomy (Group 1), patients who underwent cholecystectomy during the first pancreatitis attack upon admission and before discharge from hospital (1-3 days); and late cholecystectomy (Group 2), patients who received medical treatment during their first pancreatitis episode and underwent surgery after 4-10 weeks. Sex, Ranson scores, American Society of Anesthesiology scores, and conversion reasons were compared., Results: Group 1 and Group 2 included 75 patients (20 men, 55 women) and 87 patients (25 men, 62 women), respectively. The mean age was 44.7 years (range, 21-82 years). Obscure anatomy with adhesions was detected in 16 patients (5 in Group 1, 11 in Group 2) as the leading cause of conversion to OS, but it was not statistically significant (p=0.054). Acute inflammation with empyema and peripancreatic liquid collection was observed in 14 patients (12 in Group 1, 2 in Group 2), and conversion to OS was statistically significantly higher in Group 1 (p=0.016)., Conclusion: Timing of LC does not influence the conversion rates to OS after BP., (Copyright © 2017.

Background: The aim of this study was to investigate the validity of hook wire localization biopsy for non-palpable breast lesions which were detected by ultrasonography (USG) or mammography (MMG)., Methods: In this retrospective study, USG or MMG-guided hook wire localization technique was performed on 83 patients who had non-palpable breast lesions. Then histopathological examination was performed on surgically removed specimens. All patients' mammograms or ultrasonograms were categorized using Breast Imaging-Reporting and Data System (BI-RADS) classification., Results: Radiologically, 27 (32.53%) patients were classified as BI-RADS 3, 49 (59.04%) BI-RADS 4, one (1.2%) BIRADS 5 and six (7.23%) BI-RADS 0. Histopathological results were benign in 68 (81.9%) and malignant in 15 (18.1%) patients. Twenty-seven patients were classified as BI-RADS 3 and definitive diagnoses for all were benign. Besides, 49 patients were classified as BI-RADS 4 and histopathologically 14 of them were reported as malignant, and 35 as benign. Sensitivity of MMG was 93% and specificity was 55%. For USG, the sensitivity was 100% and the specificity was 73%., Conclusion: In early diagnosis of breast cancer, the validity of the imaging-guided hook wire localization biopsy of non-palpable breast lesions has been proved. The cooperation of surgeon, radiologist and pathologist increases the successfull results of hook wire localization technique.

Introduction: Conventional laparoscopic procedures have been used for splenic diseases and concomitant gallbladder stones, frequently in patients with hereditary spherocytosis since 1990's. The aim of this study is to evaluate the feasibility of single-site surgery with conventional instruments in combined procedures., Presentation of Case Series: Six consecutive patients who scheduled for combined cholecystectomy and splenectomy because of hereditary spherocytosis or autoimmune hemolytic anemia were included this study. Both procedures were performed via trans-umbilical single-site multiport approach using conventional instruments. All procedures completed successfully without conversion to open surgery or conventional laparoscopic surgery. An additional trocar was required for only one patient. The mean operation time was 190min (150-275min). The mean blood loss was 185ml (70-300ml). Median postoperative hospital stay was two days. No perioperative mortality or major complications occurred in our series. Recurrent anemia, hernia formation or wound infection was not observed during the follow-up period., Discussion: Nowadays, publications are arising about laparoscopic or single site surgery for combined diseases. Surgery for combined diseases has some difficulties owing to the placement of organs and position of the patient during laparoscopic surgery. Single site laparoscopic surgery has been proposed to have better cosmetic outcome, less postoperative pain, greater patient satisfaction and faster recovery compared to standard laparoscopy., Conclusion: We consider that single-site multiport laparoscopic approach for combined splenectomy and cholecystectomy is a safe and feasible technique, after gaining enough experience on single site surgery., (Copyright © 2015 The Authors.

Background: Inflammatory hematological parameters like the neutrophil/lymphocyte (N/L) ratio have been investigated in many cancer types and significant relationships found with prognosis, for example. The aim of this present study was to investigate the impact of hematological parameters notably on N/L ratio and mean platelet volume (MPV) in papillary thyroid cancer cases., Materials and Methods: A total of 79 patients who underwent a thyroidectomy operation in Findikli, Goiter Research and Treatment Center during 2011- 2015 period were enrolled in the study, 41 with papillary thyroid cancer and 38 with benign goiter confirmed by pathological examination. We collected clinical and laboratory data for the patients from hospital records retrospectively. Blood samples taken at admission were assessed for parameters compared between the groups., Results: No significant differences between papillary thyroid cancer and benign goiter groups were apparent in terms of age, the N/L ratio, MPV, white blood cell count (WBC), red blood cell count (RBC), hemoglobin, hematocrit, platelet, neutrophil, lymphocyte, red blood cell distribution width (RDW) and platelet crit (PCT) levels (>0.05). Only the level of platelet distribution width (PDW) significantly differed, being lower in the papillary cancer group (<0.05)., Conclusions: No significant relationship between papillary thyroid cancer and inflammatory hematological parameters including in particular the N/L ratio and MPV. The relevance of the PDW values remains unclear.

Introduction: Major complications of colonic anastomosis include fistula, bleeding, and anastomotic stricture, and the most common one is anastomotic leakage. Many organic or inorganic tissue adhesives are being used such as fibrin glue or cyanoacrylate to strengthen or protect colonic anastomosis. Up to now, a great number of studies have been carried out to investigate the effects of these biomaterials., Aim: To determine the effect of cyanoacrylate application on anastomosis safety., Material and Methods: In this experimental study, rats were divided into two groups; a control group and an experimental group. Full-thickness incisions were done on the left colon of the rats, and then end-to-end anastomosis was performed by using 5/0 silk separated sutures. In the experimental group we applied cyanoacrylate over the sutures. The samples were taken on the 7 th day., Results: In the control group the average tissue hydroxyproline levels and the average bursting pressures were significantly higher than in the experimental group., Conclusions: The purpose of all the experimental studies is to prevent and reduce anastomotic complications. Despite all the studies that have been done, colonic anastomosis complications continue to be a problem. As a result, we suggest that cyanoacrylate has a negative effect on the healing process of colonic anastomosis., Competing Interests: The authors declare no conflict of interest.

Aim: To evaluate the long-term effectiveness of colonic stents in colorectal tumors causing large bowel obstruction., Methods: We retrospectively analyzed data from 49 patients with colorectal cancer who had undergone colorectal stent placement between January 2008 and January 2013. Patients' symptoms, characteristics and clinicopathological data were obtained by reviewing medical records. The obstruction was diagnosed clinically and radiologically. Histopathological diagnosis was achieved endoscopically. Technical success rate (TSR) was defined as the ratio of patients with correctly placed SEMS upon stent deployment across the entire stricture length to total number of patients. Clinical success rate (CSR) was defined as the ratio of patients with technical success and successful maintenance of stent function before elective surgery (regardless of number of SEMS deployed) to total number of patients. The surgical success rate (SSR) of colorectal stent as a bridge to surgery was defined as the ratio of patients with successful surgical procedures. Unsuccessful surgical outcomes were defined as being due to insufficient colonic decompression. The technical, clinical, surgical success rates and complications after stenting were assessed., Results: The median age of patients was 64 (36 to 89). 44.9% of patients were male and 55.1% were female. Eighteen patients had the obstruction located in the rectum, 15 patients in the rectosigmoid region, 10 patients in the sigmoid region, and 6 patients had a tumor causing obstruction in the proximal colon. Each patient was categorized pathologically as stage 2 (32.7%, 16 patients) or stage 3 (42.9%, 21 patients) and 12 patients (24.4%) had metastatic disease. None of the patients received chemotherapy before stenting. Stenting was undertaken in 37 patients as a bridge to surgery, and in 12 patients stents were used for palliation. Median time to surgery after stenting was 30 ± 91.9 d. All surgery was completed in one single operation and thus no colostomy with stoma was needed. The median overall survival rate of patients with stage 2-3 colorectal cancer was 53.1 mo and stage 4 was 37.1 mo (P = 0.04). Metastatic colorectal patients who were treated palliatively with stents had backbone chemotherapy with oxaliplatin and/or irinotecan-based regimens plus antiangiogenic therapies, especially bevacizumab. Resolution of the obstruction and clinical improvement was achieved in all patients. The technical, clinical and surgical success rates were 95.9%, 100% and 94.6%, respectively., Conclusion: The efficacy and safety of colonic stents was demonstrated both as a bridge to surgery and for palliative decompression. In addition, results emphasize the importance of the skills of the endoscopist in colonic stenting.

Objective: Complications associated with wound healing after abdominal tumor operations continue to be a significant problem. This study aimed to determine the significance of retention sutures in preventing these complications. For this purpose, early and late term results of patients who underwent application of polydioxanone (PDS) and additional retention sutures for abdominal closure were retrospectively evaluated., Material and Methods: Clinical files of 172 patients who were operated due to gastrointestinal tract malignancies in our clinic between January 2007 and January 2011 were retrospectively analyzed. Patients in whom the fascia was repaired only with PDS (Group 1) were compared to patients in whom the fascia was repaired with PDS and retention sutures (Group 2) in terms of age, gender, postoperative evisceration-wound infection (<1 month), incisional hernia (>1 month), incision type, co-morbid factors, and operative time., Results: There was no significant difference between the two groups in terms of age or gender (p=0.680 and p=0.763). No significant difference was detected in terms of postoperative incisional hernia (p=0.064). Evisceration and post-operative wound infection were significantly lower in Group 2 as compared to Group 1 (p=0.008 and p=0.002). Operative time was significantly longer in Group 1 than in Group 2 (p<0.0001). Co-morbid features were significantly higher in Group 2 than in Group 1 (p<0.0001). There were no significant differences between the groups in terms of incision type (p=0.743)., Conclusion: In the presence of co-morbid factors that disrupt wound healing in surgical patients with gastrointestinal malignancy, retention suture can be safely used as a supplement for optimal wound care.
