Öğe Acoustic Radiation Force Impulse (ARFI) imaging for the distinction between benign and malignant thyroid nodules(Springer-Verlag Italia Srl, 2015) Hamidi, Cihad; Goya, Cemil; Hattapoglu, Salih; Uslukaya, Omer; Teke, Memik; Durmaz, Mehmet Sedat; Yavuz, Mehmet SiddikThe aim of the present study was to evaluate thyroid nodules using virtual touch quantification (VTQ) of force impulse acoustic radiation (ARFI) imaging and to investigate a cutoff value for the differentiation of malignant thyroid nodules. Ninety-five patients with quantitatively-assessed (VTQ) thyroid nodules were evaluated with ARFI imaging in this prospective study. ARFI imaging with VTQ was performed only on the nodules which were expected to undergo fine-needle aspiration biopsy (FNAB). All of the thyroid lesions were examined histopathologically. The mean shear wave velocity (SWV) value of the malignant nodules (3.18 +/- A 0.39 m/s) was higher than that of the benign nodules (2.11 +/- A 0.53 m/s). There was a statistically significant difference between the mean SWV values of benign and malignant nodules (p < 0.001). A SWV cutoff value of greater than 2.66 m/s yielded sensitivity and specificity values of 100 and 82.3 %, respectively, for diagnosis of malignant nodules. VTQ of ARFI imaging has high sensitivity and specificity for discriminating between benign and malignant thyroid nodules and may positively contribute to clinical evaluation of these nodules.Öğe Acute biliary pancreatitis in cholecystectomised patients(Aves, 2012) Gul, Mesut; Aliosmanoglu, Ibrahim; Turkoglu, Ahmet; Ucmak, Feyzullah; Ulger, Burak Vel; Oguz, Abdullah; Uslukaya, OmerPurpose: This study aimed to investigate the treatments of patients with acute biliary pancreatitis after cholecystectomy. Materials and Methods: Twenty-two patients who were diagnosed with acute biliary pancreatitis and underwent cholecystectomy were analysed retrospectively. The patients' demographic characteristics, severity of disease, elapsed time since cholecystectomy, whether endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy were performed, surgical intervention, duration of hospital stay, and mortality were recorded. Results: The average age of the 22 patients was 60.14 +/- 16.4 (2186), and the female to male ratio was 14:8. The average elapsed time since cholecystectomy was 81.7 (6-240) months. In 18 patients, stones and mud were detected in the choledoch duct with endoscopic retrograde cholangiopancreatography, with no factors identified in 4 patients. While 14 of these 18 patients were treated successfully with stone extraction and endoscopic sphincterotomy, endoscopic retrograde cholangiopancreatography did not succeed in 4 patients. In 3 of 4 patients, in whom stones were detected but failed to be extracted, choledoch duct exploration was carried out with open surgery. Mortality developed in one patient. Average hospital stay, with the exception of the deceased patient, was 8.5 +/- 3.5 days. Conclusion: Some choledoch duct stones can remain asymptomatic for an extended period after cholecystectomy. However, some cause acute pancreatitis ending in mortality after several months or even years. Endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy are the standard methods of treatment. Patients in whom endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy have failed, can be treated with choledoch duct exploration with open surgery and laparoscopic surgery.Öğe An Analysis on Aerodynamic and Acoustic Changes After Thyroidectomy(Int College Of Surgeons, 2016) Yilmaz, Beyhan; Bakir, Salih; Yilmaz, Edip Erdal; Senhul, Engin; Uslukaya, Omer; Gul, Aylin; Ozkurt, Fazil EmreThe purpose of this study was to investigate the aerodynamic and acoustic changes after thyroidectomy without laryngeal nerve injury by using objective methods. Voice samples of sustained /alpha/ recorded from 44 adults preoperatively and nearly 1 week and 3 months after thyroidectomy were analyzed for mean vocal fundamental frequency (Mean Fo, Hz), maximum fundamental frequency (Max Fo, Hz), minimum fundamental frequency (Min Fo, Hz), jitter, shimmer, glottal to noise excitation ratio (GNE), irregularity, noise, overall severity, S time, Z time, S/Z ratio, and maximum phonation time (MPT). Voice samples were analyzed using the lingWAVES software. The comparisons of preoperative and early and late postoperative acoustic parameters revealed significant differences in Mean F0, Max F0, MPT, and S Time between the early and late postoperative periods. The voice changes after thyroidectomy were not affected by age, sex, or surgical procedure, but they differed between the benign and malignant nature of the tumor. Patients with malignant tumors showed a greater decrease in Mean F0 and Max F0 compared with the patients with benign tumors, and this difference was statistically significant. Voice changes may occur after thyroidectomy even in the patients with no evidence of laryngeal nerve damage, and these changes can be assessed with objective measurement methods. This information should be explained to the patients during the preoperative counseling, and proper informed consent is ethically and legally required for all planned thyroidectomies.Öğe Can Mean Platelet Volume be a New Risk Factor in Portal Venous Thrombosis?(Sage Publications Inc, 2013) Aliosmanoglu, Ibrahim; Gul, Mesut; Oguz, Abdullah; Basol, Omer; Uslukaya, Omer; Keles, CelalettinBackground: The aim of this study was to discuss the possibility of mean platelet volume (MPV) being a new risk factor in the etiology of portal venous thrombosis (PVT). Methods: Study participants were categorized into 2 different groups: group I, control group (n = 35) and group II, PVT group (n = 34). Demographic data and MPV values were recorded retrospectively. Results: No differences were determined between the 2 groups regarding hypertension, diabetes mellitus, and smoking (P > .05). The average hemoglobin levels were 10.8 +/- 2.1 in group II and 14.0 +/- 1.7 in group I (P < .001). Although the MPV levels of group II patients were 8.2 +/- 0.52, the average level in group I was determined as 7.8 +/- 0.62 (P = .012). In the performed receiver-operating characteristic (ROC) analysis, the cutoff value for patients with PVT for MPV was determined as 7.9 (area under curve: 0.674), sensitivity as 70.6%, and specificity as 65.7% (P = .013). Conclusion: The current study shows that MPV is significantly higher in patients with PVT than in the control group.Öğe Combination of Virtual Touch Tissue Imaging and Virtual Touch Tissue Quantification for Differential Diagnosis of Breast Lesions(Amer Inst Ultrasound Medicine, 2015) Teke, Memik; Goya, Cemil; Teke, Fatma; Uslukaya, Omer; Hamidi, Cihad; Cetincakmak, Mehmet Guli; Hattapoglu, SalihObjectives-Breast cancer is the second leading cause of death from cancer in women, and early detection is the key to successful treatment. Unfortunately, even with technological advances, the specificity of imaging modalities is still low. Therefore, we evaluated the value of a newly developed noninvasive technique, acoustic radiation force impulse imaging, for differentiating benign versus malignant breast lesions. Methods We prospectively examined 141 breast lesions in 122 patients. All lesions were classified according to the American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) for mammography, BI-RADS for sonography, and Virtual Touch tissue imaging (VTI; Siemens Medical Solutions, Mountain View, CA) pattern. Internal and marginal shear wave velocity (SWV) values for the lesions were noted. The sensitivity, specificity, accuracy, and positive and negative predictive values for VTI and Virtual Touch tissue quantification (VTQ Siemens Medical Solutions) were calculated. Results The marginal SWV values were statistically higher in malignant lesions (mean +/- SD, 5.41 +/- 1.37 m/s) than benign lesions (2.91 +/- 0.88 m/s; P < .001). When the SWV cutoff level was set at 4.07 m/s, and the higher of the internal and marginal values was adopted, the combination of VTI and VTQ showed 95.1% sensitivity, 99.0% specificity, and 97.8% accuracy. Conclusions Breast Imaging Reporting and Data System category 4 lesions are the main focus of research for early detection of breast cancer. Unfortunately, BI-RADS category 4 assessment covers a-wide range of likelihood of malignancy (2%-95%). This wide range reflects the necessity for a more specific imaging modality. The combination of. VTI and VTQ could increase the diagnostic performance of conventional sonography.Öğe Comparing the effects of nebivolol and dexpanthenol on wound healing: an experimental study(Wiley, 2016) Ulger, Burak V.; Kapan, Murat; Uslukaya, Omer; Bozdag, Zubeyir; Turkoglu, Ahmet; Alabalik, Ulas; Onder, AkinWound healing is a dynamic, interactive process that is initiated in response to injury. A number of investigations and clinical studies have been performed to determine new approaches for the improvement ofwound healing. The aim of this studywas to compare the effects of dexpanthenol, a molecule that is widely used for improvingwound healing, and nebivolol, a molecule that increases nitric oxide release, on wound healing. A total of 30 rats were divided into three equal groups (n = 10). A linear 2 cm incision was made in the rats' skin. No treatment was administered in the first (control) group. Dexpanthenol cream was administered to the rats in the second group and 5% nebivolol cream was administered to the rats in the third group. The wound areas of all of the rats were measured on certain days. On the 21st day, all wounds were excised and histologically evaluated. The wound healing rates of the dexpanthenol and nebivolol groups were higher than those of the control group (P < 0.05). However, the wound healing rates of the dexpanthenol and nebivolol groups were not significantly different. Nebivolol and dexpanthenol have comparable effects on wound healing.Öğe Effect of Intraperitoneal Curcumin Instillation on Postoperative Peritoneal Adhesions(Karger, 2015) Turkoglu, Ahmet; Gul, Mesut; Yuksel, Hatice Kurt; Alabalik, Ulas; Ulger, Burak Veli; Uslukaya, Omer; Avci, YahyaObjective: The aim of this study was to determine the effect of curcumin on adhesion formation in a rat cecum abrasion model. Materials and Methods: Thirty Wistar rats were randomized into three groups; the control group received saline, the curcumin group received 10 mg/kg of curcumin after cecal abrasion, and in the sham group the abdominal wall was closed without any abrasion to the cecum. On day 15, adhesions were assessed blindly using a standardized scale, and histopathological samples were taken and examined. Results: There were no incisional hernias or wound dehiscences in any animals of the three groups. A comparison of adhesion scores showed a significant difference between the curcumin (median = 1) and the control group (median = 2; p < 0.05). The grade of inflammation of the curcumin (median = 1) and the sham (median = 0) group was significantly lower than that of the control group (median = 3; p < 0.01 and p < 0.001, respectively). Hydroxyproline levels were significantly lower in the sham (48.3 +/- 11.8 mu g/mg) and the curcumin (63.8 +/- 13.9 mu g/mg) group compared to the control group (85.7 +/- 22.1 mu g/mg; p < 0.05). Conclusion: These data suggest that curcumin, administered intraperitoneally, was effective in the prevention of peritoneal adhesion formation. (C) 2014 S. Karger AG, BaselÖğe The effects of roflumilast on the pancreas and remote organs in a cerulein-induced experimental acute pancreatitis model in rats(Springer, 2016) Uslukaya, Omer; Turkoglu, Ahmet; Yazgan, Umit Can; Kaplan, Ibrahim; Ibiloglu, Ibrahim; Kapan, Murat; Gumus, MetehanSystemic damage in acute pancreatitis (AP) can be characterized by oxidative stress and the release of pro-inflammatory cytokines. Roflumilast has been shown to be a potent anti-inflammatory and antioxidant agent. In the present study, we aimed to investigate the effect of roflumilast in cerulein-induced AP. Thirty-two male rats were divided into four groups: group 1 (sham), group 2 (Roflumilast), group 3 (AP), and group 4 (AP + Roflumilast). AP was induced by injecting 4 x 75 mu g/kg of body weight at an interval of 1 h. Rats were killed after 12 h following the last cerulein administration. AP was confirmed by measuring the serum amylase level and inflammatory features. Morphological changes were observed in the pancreas. Amylase levels were higher in the AP and AP + Roflumilast groups than the sham and Roflumilast groups. The serum levels of TNF-alpha, IL-1 beta, and IL-6 increased in the AP group, whereas they decreased in the Roflumilast group. The total oxidant activity (TOA) was higher and the total antioxidant capacity (TAC) was lower in the AP group. The administration of roflumilast decreased the TOA and increased the TAC in comparison with the AP group (p < 0.05 for both). Roflumilast significantly decreases oxidative stress and inflammatory mediators in the plasma, pancreas, and lung in cerulein-induced AP rats.Öğe The effects of sulforaphane on the liver and remote organ damage in hepatic ischemia-reperfusion model formed with pringle maneuver in rats(Elsevier, 2015) Oguz, Abdullah; Kapan, Murat; Kaplan, Ibrahim; Alabalik, Ulas; Ulger, Burak Veli; Uslukaya, Omer; Turkoglu, AhmetBackground: The purpose of this study was to investigate the effect of Sulforaphane on ischemia/ reperfusion (IR) injury of the liver and distant organs resulting from liver blood flow arrest. Materials and methods: Fourty Wistar rats were assigned into four groups, each included 10 rats were used. Group I as only laparatomy, Group II laparatomy and Sulforaphane application, Group III hepatic IR; and Group IV as hepatic IR and Sulforaphane application group. Animals were subjected to liver ischemia for 30 min and then reperfusion is started. 5 mg/kg Sulforaphane was applied via oral lavage 15 minutes before initiating the experimental study. Blood samples were taken from the animals for biochemical analysis at 60th minutes of the experiment in the first and second groups; 30 minutes after beginning reperfusion in the third and forth groups. Simultaneously, liver, lung and kidney tissues were sampled for biochemical and histopathological examinations. Results: The administration of sulforaphane significantly reduced the serum TOA and liver TOA levels, increased the serum TAC and liver TAC levels and also decreased The OSI and liver OSI levels. In the histopathologic examination, the injury was reduced by the administration of sulforaphane. Administration of sulforaphane did not lead to any significant changes in any parameter including histopathological parameters in both the kidney and the lung. Conclusions: Sulforaphane reduced the liver oxidative stress from I/R injury. A histological injury in liver was reduced by sulforaphane administration. However, there were no significant effects of sulforaphane on the remote organ injuries induced by IR. (C) 2015 IJS Publishing Group Limited. Published by Elsevier Ltd.

Though many studies exist regarding splenic injuries, there are not a sufficient number investigating the factors in splenic injuries influencing mortality. In this study, we aimed to investigate the factors affecting mortality in splenic injuries. MATERIALS AND METHODS: All 237 patients with splenic injury between 2005 to 2014 were retrospectively analyzed. The patients were divided into two groups, survivors and non-survivors. Age, gender, mechanism of injury, grade of splenic injury, pulse, respiratory rate, systolic blood pressure, hemoglobin levels, number of transfusions, surgical procedure, ISS, RTS and hospitalization period were recorded. Univariate and multivariate analysis were used to compare survivors and non-survivors. RESULTS: The average age of the patients was 32 and most (82.7%) were male. Mortality was observed in 18 patients (7.6%). Mortality was found significantly lower in patients who had isolated splenic injury (p=0.048). In univariate analyses, decreased RTS (p<0.001), increased number of blood transfusion (p<0.001), decreased hemoglobin level (p=0, 025) and increased ISS (p<0.001) were found significant in non-survivors. In multivariate analysis; number of transfusions, ISS and RTS were found as independent risk factors for mortality. CONCLUSIONS: We found high number of transfusions, high ISS and low RTS as independent risk factors for mortality in patients with splenic injury.Öğe Factors effective on morbidity and mortality in rectal injuries caused by penetrating and blunt traumas: a civilian experience(Drunpp-Sarajevo, 2012) Aliosmanoglu, Ibrahim; Gul, Mesut; Arikanoglu, Zulfu; Taskesen, Fatih; Uslukaya, Omer; Hakseven, MusluhPurpose: Our objective in this study is to establish the factors effecting morbidity and mortality in rectal injuries which occurred in civilian injuries. Methods: Fifty-two patients who had been hospitalized for rectal injuries are evaluated. Patients are arranged in two groups according to the etiology: Group I rectal injuries caused by penetrating traumas; Group II rectal injuries caused by blunt traumas. To determine the risk factors, demographic data of the patients are compared. Results: Group I consisted of 35 male and 2 female patients and average age was 27,5 +/- 7,5, while Group II consisted of 12 male and 3 female patients, and average age was 32,8 +/- 12,4 (p>0.05). Mean average of ISS was 10.1 +/- 10.1 in Group I and 19.4 +/- 12.1 in Group II (p=0.014). However, mean average of TRISS was 98.5 +/- 1.4 in Group I, and 96.4 +/- 3.5 in Group II; and the difference was statistically significant (p=0.011). Mortality numbers for the groups were 1 patient in Group I (2.7 %), 3 patients in Group II (20%), (p=0.034). Conclusions: Although rectal injuries are rarely seen in clinic, morbidity and mortality rates are high. So, being aware of the risk factors and developing a therapy plan, considering the patient is important for the success of therapy.Öğe Factors that Affect Drain Indwelling Time after Breast Cancer Surgery(Aves, 2016) Uslukaya, Omer; Turkoglu, Ahmet; Gumus, Metehan; Bozdag, Zubeyir; Yilmaz, Ahmet; Gumus, Hatice; Kaya, SeyhmusObjective: The most common procedure to prevent seroma formation, a common complication after breast and axillary surgery, is to use prophylactic surgical drains. Ongoing discussions continue regarding the ideal time for removing drains after surgical procedures. In this study, we aimed to investigate factors that affect drain indwelling time (DIT). Materials and Methods: From 2014 to 2015, a total of 91 consecutive patients with breast cancer were included in the study. The demographic characteristics of the patients, treatment methods, histopathologic features of the tumor, size of removed breast tissue (BS), tumor size (TS), number of totally removed lymph nodes (TLN), and metastatic lymph nodes (MLN), whether they had neoadjuvant chemotherapy, and the DIT were retrospectively recorded from the hospital database. Results: The mean age of the patients was 48.9 years, and the mean DIT was 4.8 days. The mean size of breast removed was 17.3 cm and tumor size was 4.7 cm, and the mean number of metastatic lymph nodes was 3.3, and mean total number of lymph nodes was 14.1. Patients who had neoadjuvant chemotherahpy had longer DIT. There was a positive correlation between the BS, TS, TLN, MLN, length of hospital stay, and DIT. Linear regresion analysis revealed that the BS, TLN, and history of neoadjuvant chemotherahpy were independent risk factors for DIT. Conclusion: DIT primarily depends on BS, TLN, and history of neoadjuvant chemotherahpy. A policy for the management of removing drains to prevent seroma formation should thus be individualized.Öğe Fasciola hepatica infection at a University Clinic in Turkey(J Infection Developing Countries, 2014) Ulger, Burak Veli; Kapan, Murat; Boyuk, Abdullah; Uslukaya, Omer; Oguz, Abdullah; Bozdag, Zubeyir; Girgin, SadullahIntroduction: We aimed to analyze the approaches to the diagnosis and treatment of patients with fascioliasis in light of current literature. Methodology: Thirty-nine patients with fascioliasis admitted to the Surgery Clinic of Dicle Medical Faculty (Turkey) were included in this study. The demographic, clinical, diagnostic, treatment and outcome data were analyzed retrospectively. Results: Abdominal pain (n = 37; 95%) and eosinophilia (n = 31; 79%) were the most common findings. Twenty-seven patients were diagnosed by clinical and radiological findings. Patients were treated with triclabendazole. Thirty-six (92.4%) of the patients improved after medical treatment. Conclusions: The presence of typical clinical, laboratory and radiological findings is sufficient for diagnosis. Triclabendazole administration is often an effective treatment, with improvements occurring over the course of a few months.Öğe Gangrenous Cholecystitis: Mortality and Risk Factors(Int College Of Surgeons, 2015) Onder, Akin; Kapan, Murat; Ulger, Burak Veli; Oguz, Abdullah; Turkoglu, Ahmet; Uslukaya, OmerAs a serious complication of cholelithiasis, gangrenous cholecystitis presents greater mortality than noncomplicated cholecystitis. The aim of this study was to specify the risk factors on mortality. 107 consecutive patients who underwent surgery due to gangrenous cholecystitis between January 1997 and October 2011 were investigated retrospectively. The study included 60 (56.1%) females and 47 (43.9%) males, with a mean age of 60.7 6 16.4 (21-88) years. Cardiovascular diseases were the most frequently accompanying medical issues (24.3%). Thirty-six complications (33.6%) developed in 29 patients, and surgical site infection was proven as the most common. Longer delay time prior to hospital admission, low white blood cell count, presence of diabetes mellitus, higher blood levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and total bilirubin, pericholecystic fluid in abdominal ultrasonography, and conversion from laparoscopic surgery to open surgery were identified as risk factors affecting mortality (P < 0.001, P = 0.001, P = 0.044, P = 0.005, P = 0.049, P = 0.009, P = 0.022, P = 0.011, and P = 0.004, respectively). Longer delay time prior to hospital admission and low white blood cell count were determined as independent risk factors affecting mortality.Öğe Giant myxoid liposarcoma of descending mesocolon origin(Termedia Publishing House Ltd, 2014) Uslukaya, Omer; Taskesen, Fatih; Aliosmanoglu, Ibrahim; Arikanoglu, Zulfu; Gul, Mesut; Dusak, AbdurrahimLiposarcomas are one of the most common primary lesions of the retroperitoneal region. They rarely exhibit intra-abdominal location. Because the symptoms emerge later on, they often remain unnoticed until they grow large. Our aim in this paper is to present a case of myxoid liposarcoma of descending mesocolon origin, 40 cm wide and weighing 7000 g, seen in a 47-year-old male patient. No cases at this weight and radius, originating from descending mesocolon, belonging to the myxoid sub-type, were found in our literature scan.Öğe Improvement of minimally invasive parathyroidectomy outcomes by real time ultrasonography performed by a surgeon and radiologist team(Soc Romana Ultrasonografe Medicina Biologie-Srumb, 2015) Uslukaya, Omer; Gumus, Metehan; Tasdemir, Bekir; Goya, Cemil; Kilinc, Faruk; Oguz, Abdullah; Turkoglu, AhmetAims: Minimally invasive parathyroidectomy (MIP) has become the first line of treatment for primary hyperparathyroidism caused by solitary parathyroid adenoma. In order to increase the sensitivity of high-resolution ultrasonography (hUS), surgeon performed ultrasonography (SUS) has been increasingly used preoperatively. However, a radiologist and surgeon performing ultrasonography (RSUS) has not been a usual practice. In this study, we aimed to evaluate the clinical contribution of RSUS on MIP. Material and methods: From 2012 to 2014, a total of 30 consecutive patients (4 male, 26 female, mean age 48.87 +/- 14.52 years) with solitary parathyroid adenoma, were included in the study. All patients underwent preoperative hUS and Technetium-99m sestamibi scintigraphy. In patients, demographic characteristics, diagnostic tools used, levels of biochemical parameters, duration of operation, and length of hospital stay were recorded. Results: Adenomas were successfully localized by US in all patients and the surgical approach was determined according to this localization. Parathyroidectomy with MIP was successfully performed under local anesthesia in all patients. Mean operation time was 19.87 +/- 3.35 min. Postoperative PTH and calcium values were significantly decreased. All patients were discharged from the hospital in the same day. None of the patients had complications such as recurrent laryngeal nerve injury, hematoma, or injury to nearby organs. None of the patients had drains placed. Conclusions: Adenoma is well localized by US and thus, MIP can be completed under local anesthesia. US provides a very important clinical contribution to the success of MIP. In addition to these, RSUS helps in determining the location of the incision and the shortest way to achieve the lesion; therefore, it provides a small incision and shortens duration of the operation with a minimal dissection.Öğe Is Ostomy Still Mandatory in Rectal Injuries?(Int College Of Surgeons, 2013) Ulger, Burak Veli; Turkoglu, Ahmet; Oguz, Abdullah; Uslukaya, Omer; Aliosmanoglu, Ibrahim; Gul, MesutThe aim of this study was to compare the outcomes of the treatment methods of ostomy and primary repair in rectal injuries. A total of 63 patients with rectal injury who had been treated at Dicle University Hospital between 2000 and 2011 were retrospectively reviewed. To determine the outcomes of the treatment methods, the patients were divided into 2 groups (ostomy group: patients who underwent ostomy plus primary repair; repair group: patients who only underwent primary repair) and compared. The patients included 51 men and 12 women. A total of 44 patients underwent ostomy, whereas 19 patients underwent primary repair. No morbidity was detected in either group with grade II intraperitoneal rectal injury. The outcomes of the patients with grade II intraperitoneal and extraperitoneal rectal injury were similar. In the treatment of patients with low-grade rectal injuries, primary repair can be preferred to ostomy.Öğe The Management and Outcomes of Male Breast Cancer(Aves, 2016) Uslukaya, Omer; Gumus, Metehan; Gumus, Hatice; Bozdag, Zubeyir; Turkoglu, AhmetObjective: Due to a lack of sufficient data, the treatment protocols for male breast cancer are usually the same as those used for female breast cancer. The aim of the current study was to present our clinical experience with male breast cancer. Materials and Methods: The records of 37 patients who were treated for male breast cancer in our hospital between 2004 and 2014 were reviewed retrospectively. The data of patients were recorded and analyzed. Results: The mean age of the patients was 63.03 +/- 12.36 years. Thirty-three patients (89.2%) had invasive ductal carcinoma, two (5.4%) had ductal carcinoma in situ, and two had invasive lobular carcinoma (5.4%). The most common molecular subtype was luminal A (17 cases, 45.9%). Twenty-nine patients with male breast cancer underwent mastectomy and two underwent breast conserving surgery. Axillary lymph node dissection was performed in 25 patients. The most common surgical procedure was modified radical mastectomy. Distant metastases were present in 17 (45.9%) patients. Overall, the 5-year survival was 60%. The 5-year survival was 100% for those with stage 0-I disease, 87% for stage II, and 42% for stage III. The 3-year survival was 14% for stage IV. Conclusion: Patients with male breast cancer presented at an older age, a later stage, and with earlier metastasis. Early metastasis and death increases with increasing stage. Poor prognosis correlates with late admission. Data from different centers should be compiled and reviewed in order to determine a specific treatment protocol for male breast cancer; each paper published reveals new data.Öğe New hormones to predict the severity of gallstone-induced acute pancreatitis(Aves, 2014) Ulger, Burak Veli; Gul, Mesut; Uslukaya, Omer; Oguz, Abdullah; Bozdag, Zubeyir; Yuksel, Hatice; Boyuk, AbdullahBackground/Aims: Levels of the hormones ghrelin and leptin in rat models of acute pancreatitis (AP) have been investigated in several experimental studies. However, there are very few clinical studies addressing the connection between hormone levels and AP. A few recent studies investigating the changes in ghrelin and leptin levels in patients with AP have been reported; however, our study is the first clinical study to investigate the change of nesfatin-1 levels in patients with gallstone-induced AP. Materials and Methods: Forty patients were enrolled in this study, eight of which presented with severe AP. Two blood samples were obtained from each study patient. The first blood samples were obtained at patient admission to the hospital and the second was obtained at patient discharge. All samples were collected after at least 6 h of fasting. Plasma nesfatin-1, leptin, and ghrelin levels were measured. Results: In all 40 patients, nesfatin-1 and leptin levels were higher at admission and had decreased at discharge. In contrast, the ghrelin levels at discharge were significantly higher than those at admission. Only the changes in these hormones in the mild AP group were significant. Conclusion: Levels of these hormones were altered during the course of gallstone-induced AP. These changes might be associated with the clinical outcomes of the disease. To clarify whether the magnitude of the change in hormone levels at AP onset can be used as a biomarkers to predict the severity of the disease requires further investigation.Öğe The protective effects of roflumilast in rat acute pancreatitis model(Wiley-Blackwell, 2015) Uslukaya, Omer; Turkoglu, Ahmet; Yazgan, Umit Can; Kaplan, Ibrahim; Ibiloglu, Ibrahim; Kapan, Murat; Gumus, Metehan[Abstract Not Available]
