Background The aim of this prospective study was therefore to evaluate the diagnostic value of preoperative serum High Mobility Group Box Protein-1 (HMGB-1) levels in patients with Acute Appendicitis (AA) who show normal white blood cell count (WBC) counts. Method Our study was carried out from October 2010 through November 2010 and included 20 healthy control group participants and 60 patients who presented at the emergency department of Erzurum Training and Research Hospital in Turkey with acute abdominal pain complaints, who were pathologically diagnosed with AA after laparotomy, and who agreed to participate in the study. Results Of the 60 patients who underwent appendectomies, 36 were male and 24 were female, and of the healthy group, 12 were male and 8 female. The age averages of the patients in Groups 1, 2 and 3 were, respectively, 31.3+15.4, 34.0+16.3 and 31.0+13.1 years. The WBC averages of Groups 1, 2 and 3 were, respectively, 7.41+2.02 (x109/L), 15.71+2.85 (x109/L) and 8.51+1.84 (x109/L). The HMGB-1 levels for Groups 1 (healthy persons), 2 (AA patients with high WBC counts ) and 3 (AA patients with normal WBC counts) were, respectively, 21.71 ± 11.36, 37.28+13.37 and 36.5 ± 17.73 ng/ml. The average HMGB-1 level of the patients with AA was 36.92 ± 15.43 ng/ml while the average HMGB-1 value of the healthy group was 21.71 ± 11.36 ng/ml. Conclusion The significantly higher levels of HMGB-1 in AA patients compared to healthy persons infer that HMGB-1 might be useful in the diagnosis of AA. Use of HMGB-1, especially in patients with normal WBC counts, will reduce the number of unnecessary explorations.

- Abstract
Intravenous fluids are being widely used in patients of all ages for preventing or treating dehydration in the intensive care units, surgeries in the operation rooms, or administering chemotherapeutic drugs at hospitals. Dextrose, Ringer, and NaCl solutions are widely received as intravenous fluids by hospitalized patients. Despite their widespread administration for over 100 years, studies on their influences on different cell types have been very limited. Increasing evidence suggests that treatment outcomes might be altered by the choice of the administered intravenous fluids. In this study, we investigated the influences of intravenous fluids on human endothelial (HUVEC) and monocyte (U937) cell lines using the magnetic levitation technique. Our magnetic levitation platform provides label-free manipulation of single cells without altering their phenotypic or genetic properties. It allows for monitoring and quantifying behavior of single cells by measuring their levitation heights, deformation indices, and areas. Our results indicate that HUVEC and U937 cell lines respond differently to different intravenous fluids. Dextrose solution decreased the viability of both cell lines while increasing the heterogeneity of areas, deformation, and levitation heights of HUVEC cells. We strongly believe that improved outcomes can be achieved when the influences of intravenous fluids on different cell types are revealed using robust, label-free, and efficient methods.

- Abstract
Hydrodynamic cavitation (HC) is a phase change phenomenon, where energy release in a fluid occurs upon the collapse of bubbles, which form due to the low local pressures. During recent years, due to advances in lab-on-a-chip technologies, HC-on-a-chip (HCOC) and its potential applications have attracted considerable interest. Microfluidic devices enable the performance of controlled experiments by enabling spatial control over the cavitation process and by precisely monitoring its evolution. In this study, we propose the adjunctive use of HC to induce distinct zones of cellular injury and enhance the anticancer efficacy of Doxorubicin (DOX). HC caused different regions (lysis, necrosis, permeabilization, and unaffected regions) upon exposure of different cancer and normal cells to HC. Moreover, HC was also applied to the confluent cell monolayer following the DOX treatment. Here, it was shown that the combination of DOX and HC exhibited a more pronounced anticancer activity on cancer cells than DOX alone. The effect of HC on cell permeabilization was also proven by using carbon dots (CDs). Finally, the cell stiffness parameter, which was associated with cell proliferation, migration and metastasis, was investigated with the use of cancer cells and normal cells under HC exposure. The HCOC offers the advantage of creating well-defined zones of bio-responses upon HC exposure simultaneously within minutes, achieving cell lysis and molecular delivery through permeabilization by providing spatial control. In conclusion, micro scale hydrodynamic cavitation proposes a promising alternative to be used to increase the therapeutic efficacy of anticancer drugs.

- Abstract
Glioblastoma multiforme is one of the most aggressive malignant primary brain tumors. To design effective treatment strategies, we need to better understand the behavior of glioma cells while maintaining their genetic and phenotypic stability. Here, we investigated the deformation and migration profile of U87 Glioma cells under the influence of dielectrophoretic forces. We fabricated a gold microelectrode array within a microfluidic channel and applied sinusoidal wave AC potential at 3 V
pp , ranging from 30 kHz to 10 MHz frequencies, to generate DEP forces. We followed the dielectrophoretic movement and deformation changes of 100 glioma cells at each frequency. We observed that the mean dielectrophoretic displacements of glioma cells were significantly different at varying frequencies with the maximum and minimum traveling distances of 13.22 µm and 1.37 µm, respectively. The dielectrophoretic deformation indexes of U87 glioma cells altered between 0.027-0.040. It was 0.036 in the absence of dielectrophoretic forces. This approach presents a rapid, robust, and sensitive characterization method for quantifying membrane deformation of glioma cells to determine the state of the cells or efficacy of administrated drugs.- Published

- Abstract
Colonoscopy, which is routinely performed in diagnosis and treatment of colorectal disorders, is a reliable procedure. Its most frequent complications are bleeding and perforation. Splenic rupture is a very rarely met complication of colonoscopy, and delay in its diagnosis leads to increased morbidity and mortality. We presented a 69 years old female patient, who was diagnosed by computerized abdominal tomography, performed for her abdominal pain, which started following the colonoscopy. After 15 days of medical treatment and follow-up, laparoscopic splenectomy was performed one month after her colonoscopy. The patient was discharged on her 4(th) postoperative day, with uneventful recovery. In patients who have complaint of abdominal pain following colonoscopy, an intraabdominal pathological condition should be considered and computerized abdominal tomography should be performed. If there is no detected intraperitoneal bleeding, in other words, if there is a sub-capsular hematoma of the spleen, medical management by monitoring the vital signs may be preferred. Then, splenectomy should be performed at an appropriate time.

- Abstract
Objective: Advances in choledochoscopy technology lead to an improvement in the diagnosis and treatment of hepatopancreatobiliary diseases. The aim of this study is to reveal the role of choledochoscopy in hepatopancreatobiliary pathologies., Materials and Methods: Choledochoscopy was used under general anesthesia in operation rooms. Flexible choledochoscope inserted via a vertical choledochotomy line, which was closed by primary closure, T-tube application, or choledochoduodenal anastomosis. Olympus CHF T 20 flexible choledochoscope and related endoscopic instruments were used for the procedures. The records were evaluated retrospectively., Results: This study presents the findings of 235 intraoperative choledochoscopy procedures. The most common indications were suspected common bile duct stone in 96 patients (40.9%), serum cholestatic enzyme increase without jaundice in 52 (22.1%), obstructive jaundice and/or serum bilirubin increase in 46 (19.6%), and presence of dilated choledoch in 42 (17.9%). Additional endoscopic diagnostic and/or therapeutic procedures were performed 156 times in 125 patients (53.2%), and endoscopic biliary stone removal was the most used procedure (87 patients, 37.0%). The mean choledochoscopy duration was 8.5 minutes (range: 5-25 minutes). Choledochoscopy confirmed preliminary diagnosis in 117 patients (49.8%), while different data were elicited in 68 (28.9%), and normal findings were found in 50 (21.3%). In this series, no choledochoscopy-related mortality was seen, and some complications occurred in 4 patients (1.7%)., Conclusion: Intraoperative flexible choledochoscopy is a proper technique in the diagnosis and treatment of hepatopancreatobiliary disorders.

- Abstract
Though frequently observed in children, intussusception is a rare state in adults. The treatment of intussusception in adults is different. In this trial, we have presented intussusception cases in adults that were treated and followed up in our department. The records of 31 adult intussusception cases surgically treated in our department between January 1993 and July 2012 were evaluated retrospectively. Among the 31 adult cases of intussusception that were treated during a period of 19 years, 10 were men, and 21 were women. The mean age was determined as 39.7 ± 5.3. The presentation symptom was abdominal pain in all the patients. Failure to pass gas or feces was observed in 23 patients (74.2 %); nausea and vomiting, in 22 patients (70.9 %); hematochezia, in 16 patients (51.6 %); and weight loss, in 3 patients (9.6 %). The mean duration of symptoms was 4.8 days. Abdominal tenderness was found in all the patients. Muscular defense and rebound tenderness were determined in 13 patients (41.9 %). Findings of intussusception were found in 80.9 % of patients examined by abdominal ultrasonography and in 63.1 % of cases examined by computerized tomography. Resection of the intussuscepted bowel segment was performed in 87 % of the patients. In conclusion, intussusception in adults is a rare clinical entity. Intussusception should be considered in the differential diagnosis in patients presenting with spasmodic abdominal pain, especially in cases with intestinal obstruction. The recommended surgical method is en bloc resection of the intussuscepted segment in cases suspected to carry a risk of malignancy.

- Abstract
Hydatid cyst disease, which is endemically observed and an important health problem in our country, involves the spleen at a frequency ranking third following the liver and the lungs. In this study, we aimed to evaluate the efficacy and results of management in splenic hydatid cysts. The demographic data, localization, diagnosis, treatment methods, and the length of postoperative hospital stay of patients with splenic hydatid cysts in a 12-year period were evaluated retrospectively. Seventeen cases were evaluated. Among these, 13 were females and four were males. Seven had solitary splenic involvement, eight had involvement of both the spleen and the liver, and two had multiple organ involvement. Ten had undergone splenectomy, one had undergone distal splenectomy, and the remaining cases had undergone different surgical procedures. The patients had received albendazole treatment in the pre- and postoperative period. One patient had died secondary to hypernatremia on the first postoperative day. The clinical picture in splenic hydatid cysts, which is seen rarely, is usually asymptomatic. The diagnosis is established by ultrasonography and abdominal CT. Although splenectomy is the standard mode of treatment, spleen-preserving methods may be used.

- Abstract
Objective: Typhoid fever (TF) is an important health problem in developing countries, and typhoid intestinal perforation (TIP) is a serious complication of TF. The present report aims to determine the clinical importance of TIPs for the last 36 years in our region, eastern Anatolia., Materials and Methods: The clinical records of 84 surgically treated cases with TIPs were reviewed retrospectively., Results: When the last 36-year period was sectioned by 6-year periods, the distribution of TIPs was found as 39 (46.4% of total), 31 (36.9%), 7 (8.3%), 4 (4.8%), 2 (2.4%) and 1 (1.2%), respectively. The mean age of the patients was 37.1 years (range: 7-68 years), and 66 patients (78.6%) were male. As a surgical procedure, 34 patients (40.5%) had primary repair, 9 (10.7%) had wedge resection with primary repair, 9 (10.7%) had resection with primary anastomosis, 28 (33.3%) had resection with ileostomy, and 4 (4.8%) had exteriorization. Complications were seen in 71 patients (84.5%), while the mortality rate was 10.7% (9 patients)., Conclusion: Although eastern Anatolia is an endemic region for TF, a certain decrease in the incidence of TIPs was found for the last 36 years. Keeping in mind the TIP, patients with TF may improve the prognosis of this serious disease.

- Abstract
Pneumatosis cystoides intestinalis (PCI), with an unknown etiology, is an uncommon disease characterized by the presence of multiple gas-filled cysts within the submucosa or subserosa of the intestinal wall. Intestinal obstruction and/or perforation are relatively uncommon complications associated with PCI. The patients are often prone to misdiagnosis or mistreatment. The diagnosis of PCI is based on plain radiography or endoscopy. Multidetector computed tomography (MDCT) provides data on other intra-abdominal pathologies. Therefore, it is an important modality for the diagnosis of PCI. We present a case of PCI in a 58-year-old man affected by peritoneal free air with multidetector computed tomography imaging findings. We performed the plain film of the abdomen, and MDCT studies that showed numerous, diffuse, bubble-like intramural gas collections into the jejunum, ileum, and colon walls at the left-upper quadrant of the abdomen. MDCT findings were confirmed by surgical exploration.

- Abstract
Background: We investigated the utility of the red cell distribution width (RDW) in diagnosing acute mesenteric ischemia (AMI) in patients with abdominal pain., Methods: The patients were divided into two groups in this retrospective case-control study: patients with AMI and patients with abdominal pain who did not require urgent surgery. Venous blood was collected from the patients upon admission to the emergency department, and abdominal computed tomography angiography was performed. The RDW and hematological and biochemical parameters of the groups were compared. The primary outcome was AMI among the patients with abdominal pain. The secondary outcome was mortality, complaint period, and size of ischemia/necrosis among the AMI patients., Results: The RDW, white blood cell lactate dehydrogenase, and blood urea nitrogen of the patients with AMI were significantly different from those of the control group. When the average RDW (15.04 %) of the patients with AMI was used as a cut-off value, the sensitivity, specificity, positive likelihood ratio (+LR), and negative likelihood (-LR) were 40.8 %, 81.2 %, 2.17, and 0.73, respectively. When patients with AMI and anemia were included in the group, the sensitivity and specificity values did not change. There was no relation between the RDW and mortality, size of the ischemia/necrosis, and complaint period. Furthermore, there was no significant difference in the average RDW between the patients with ischemia/necrosis in the small intestine only and those with ischemia/necrosis in the colon., Conclusion: The RDW on admission is of marginal help to diagnose AMI among patients with abdominal pain.

- Abstract
Background: Previous studies have evaluated the presence of juxtapapillary duodenal diverticula (JPDD) and the association with pancreatobiliary disease, but not the association of the papilla with an existing JPDD. We investigated the association of different localizations of the papilla with JPDD., Methods: We studied patients in whom JPDD was detected during endoscopic retrograde cholangiopancreatography. Patients were classified into 3 groups: 1) papilla located inside the diverticulum, 2) papilla located at the edge of the diverticulum and 3) papilla located closer than 3 cm to the diverticulum. The patients were examined with respect to localization of papilla-diverticula and to the association of the localization with pancreaticobiliary disease., Results: We enrolled 274 patients in our study. Biliary stone disease more frequently existed in group 3. The number of patients presenting with obstructive jaundice was higher in groups 2 (83.6%) and 3 (83.3%) than group 1 (66%). Cholangitis was more common in group 1 (21.3%) than in groups 2 (6.7%) and 3 (2.3%). The presence of biliary stone disease among patients presenting with pancreatitis was significantly different between groups 1 and 3 (p = 0.013) and between groups 2 and 3 (p = 0.017). The common bile duct more frequently contained stones or sludge in group 3 than in groups 1 and 2., Conclusion: When the papilla is located close to the JPDD, the incidence of biliary stone disease decreases, and pancreatobiliary diseases are caused mostly in the absence of biliary stone disease.

- Abstract
Obturator hernia is a rare hernia in the world, diagnosed late since it has no specific symptoms and findings and generally occur in thin and old women with comorbidity.For this reason obturator hernia has high morbidity and mortality rates. In this study, we present an obturator hernia case that Howship-Romberg sign is positive and has typical appearance in computerized tomography. Laparotomy was performed on 89 years old female patient with body mass index 18.08 kg/m(2) by low middle line incision. Following the segmentectomy to the strangulated small bowel loop, obturator canal is repaired by retroperitoneal application. No complication occurred in the postoperative period. Obturator hernia should be taken into consideration in old and thin female patients with intestinal obstruction. Computerized tomography should be performed for early diagnosis of the obturator hernia.

- Abstract
Background: This study investigated the effect of thiamine pyrophosphate (TPP) on oxidative liver damage induced in rats with high-dose paracetamol., Methods: Rats for this experiment were divided into the following groups: healthy control, paracetamol control, thiamine + paracetamol, TPP + paracetamol, and N-acetylcysteine + paracetamol. Oxidant and antioxidant parameters and liver function test levels were compared between the groups., Results: The results show that TPP and N-acetylcysteine with paracetamol equally prevented a rise in oxidants such as malondialdehyde and nitric oxide. They also prevented a decrease in enzymatic and nonenzymatic antioxidants such as glutathione, glutathione peroxidase, glutaredoxin, glutathione S-transferase, superoxide dismutase, and catalase in the rat liver., Conclusion: Thiamine pyrophosphate and N-acetylcysteine had a similar positive effect on oxidative damage caused by paracetamol hepatotoxicity. These findings show that TPP may be beneficial in paracetamol hepatotoxicity., (Copyright © 2014. Published by Elsevier B.V.)

- Abstract
Objective: After thyroidectomy hypocalcaemia is the most significant complication for clinicians. In this study, we investigated the factors associated with development of hypocalcaemia after thyroidectomy., Materials and Methods: We investigated the patients prospectively for age, gender, preoperative diagnosis, hormonal status, operative time, operating surgeon, existence of parathyroid gland injury at the operation, parathyroid gland auto-transplantation, preoperative use of anti-thyroid drugs and amount of bleeding at the operation. After operation in 1 and 2 days, serum calcium and phosphor, and in the 1 day parathyroid hormone values were evaluated. The chi-square test was applied in the analysis of categorical variables. Logistic regression model was used to determine the risk of hypocalcaemia in the univariate analysis., Results: Hypocalcaemia developed in 47 of 196 patients. Female gender, preoperative diagnosis of thyroid cancer and toxic nodular goitre, <3cm nodule size, parathyroid injury and auto-transplantation and low vitamin D levels were factors found to be associated with hypocalcaemia in the Logistic regression analysis., Conclusion: The factors associated with hypocalcaemia were defined to be "gender, preoperative diagnosis, parathyroid gland injury, nodule size and vitamin D deficiency", it is a multifactorial problem and it would not be proper to define a few etiological factors.

- Abstract
Objective: Blue code systems (BCS) are communication systems that ensure the most rapid and effective resuscitation when a patient is in respiratory or cardiac arrest. A hospital employee faced with the situation of a cardiopulmonary arrest (CPA) starts the system by dialing 6666 from any phone in the hospital. We created a five-person team that includes a doctor, nurse, anesthesia technician, stretcher officer and security guard. The purpose of this study is to share our experiences in initiating the use of the BCS in our hospital., Materials and Methods: In our hospital, the records of calls that were made by Callvision BCS were analyzed retrospectively from May 2010 to the end of January 2011., Results: A total of 474 calls were made using the blue code system. Of those calls, 402 (84.5%) were determined to be inappropriate calls. The remaining 72 calls were responded to. Of the 72 patients who were treated, 21 were discharged after they were hospitalized in the service or intensive care unit, 45 cases resulted in exitus, and 5 cases were referred to the Ataturk University faculty of medicine., Conclusion: The BCS has achieved its goal. The discharge rate of 29.5% that we achieved is a successful result.

- Abstract
Aim: Intestinal anastomoses are always risky in patients who develop intra-abdominal sepsis. In this study, the effects of combined glutamine and growth hormone (GH) on healing of intestinal anastomosis following intestinal repair in the rat intra-abdominal sepsis was induced., Material and Methods: Forty Sprague Dawley Albino rats at 10 weeks weighing between 180 and 240 g were included in the study. All the animals were divided into five groups comprising eight rats each. In the control group, no treatment was given in addition to the routine oral nutrition before and after surgery. In the other groups, following surgery, oral glutamine was given at a dose of 1 mg/kg/d in the glutamine group, subcutaneous GH was given at a dose of 1 mg/kg/d in the GH group, and combined glutamine and GH were administered at the same doses in the glutamine + GH group. In rats, a clinical model mimicking intestinal fistula was generated and fistula repair was performed, and the bursting pressure of the repair area and tissue hydroxyproline level of the repair area were calculated., Results: Compared with the control group, glutamine, GH, and combined groups displayed significantly higher mean bursting pressures and tissue hydroxyproline levels., Conclusion: In order to decrease the risks originating from impaired mechanisms due to intra-abdominal sepsis, and to make anastomosis safer, combined use of glutamine and GH increases the bursting pressure of anastomosis. While the use of either of these two substances alone is effective, combined use makes this effect more prominent., (Copyright © 2013 Elsevier Inc. All rights reserved.)

- Abstract
Background: The burn wound represents a susceptible site for opportunistic colonization by organisms of endogenous and exogenous origin. Diminishing appetite is known to occur in patients with burn infection, yet its underlying reason is not fully understood. We have examined the levels of nesfatin 1, a protein that we consider to be a potential new treatment target for the solution of appetite and nutrition problem in patients with burn infection., Objectives: The aim of the present study was therefore to examine nesfatin levels in patients with burn infection., Material and Methods: Laboratory values, medication and dietary records, and patient notes with diagnostic information of burn wounds patients who were admitted to the Division of Burn Treatment Center were obtained from the Erzurum Region Education and Research Hospital electronic database. Post-burn wound infection was objectively assessed by culturing wound homogenates from skin tissue. The main immediate inflammatory stress response parameters assessed were serum CRP concentrations, WBC counts, and blood nesfatin concentrations., Results: Scalding was the predominant cause of burns in both categories of patients. In 19 (61.3%) burn wound infection patients, the burns were due to a scald. A significant difference was found for the nesfatin, CRP, and WBC levels between the patients and the control group (P = 0.000). A significant difference was also determined between the nesfatin, CRP, and WBC figures at the time of hospitalization and at discharge from the hospital (P = 0.000). The most predominant bacterial isolate was Pseudomonas aeruginosa 16 (51.6%) followed by Methicilline resistant Staphylococcus aureus (MRSA) 7 (22.6%)., Conclusions: We showed that the serum nesfatin 1 level was significantly lower in the patients with burn than in the control group in our study. We considered that the central nesfatin 1 system should be taken into consideration, rather than the peripheric nesfatin 1 system, when considering the regulation of appetite in patients with burns and particularly those accompanied by infection. In other explanation of the observed negative correlation between nesfatin 1 and burn wound infection suggests that nesfatin 1 may indicate the possible contribution of nesfatin 1 to the energy homeostasis.

- Abstract
Background and Objectives: Sigmoid gangrene develops in 6.1% to 93.4% of sigmoid volvulus (SV) cases, and increases the mortality rate from 0% to 40% without bowel gangrene to 3.7% to 80%. This study aimed to investigate factors that induce bowel gangrene development in SV patients., Design and Settings: Retrospective study from a single center., Patients and Methods: We determined whether there was any correlation between sigmoid gangrene and the following factors: age, gender, a previous history of a volvulus, previous history of abdominal surgery, pregnancy, major comorbidities, shock, duration of symptoms, direction and degree of rotation of volvulus, and ileosigmoid knotting., Results: Of 442 patients, 271 (61.3%) had sigmoid gangrene. The presence of pregnancy was negatively cor.related with sigmoid gangrene development (P < .05), while comorbid diseases (P < .01), associated shock (P < .01), prolonged symptom duration (P < .05), overrotation (P < .05), and associated ileosigmoid knotting (P < .01) were positively correlated with bowel gangrene. However, no correlation was observed between sigmoid gangrene and the other studied factors., Conclusion: An inverse correlation between pregnancy and sigmoid gangrene was observed. On the other hand, a positive correlation was noted between bowel gangrene and comorbid diseases, shock, prolonged duration of symptoms, overrotation, and associated ileosigmoid knotting.

- Abstract
Background: The aim of this study is to determine the percentage of intra-abdominal hemorrhage (PIAH) on computerized tomographic (CT) scan via the Cavalieri method and to define whether this is correlated with the outcome., Methods: Fifty-one patients (24 children and 27 adults) with blunt hepatic injury were studied in this Level III prognostic clinical cohort study. The stereologic method of point counting based on the Cavalieri approach was adapted to CT data so as to assess IAH and abdominal volume. PIAH was calculated as intra-abdominal fluid volume/whole abdominal volume × 100., Results: Mean PIAHs in children and adults were 4.20% ± 2.85% and 6.28% ± 5.21%, respectively. Coexisting intra-abdominal injuries in children and in adults were as follows: splenic injury (29.2, 11.1%; p = 0.012), kidney (25, 11.1%), bladder (4.2, 14.8%), and pelvic fracture (12.5, 11.1%). PIAH was moderately negatively associated with hemoglobin levels (r = -0.301; p = 0.032), hematocrit levels (r = -0.322; p = 0.021), and GCS (Glasgow Coma Scale) score (r = -0.276; p = 0.05). Neither receiver operating characteristic curve analyses for PIAH nor outcomes were statistically significant in children. In adults, sensitivity and specificity of PIAH in predicting the prognoses when the cutoff levels were taken as 5.39%, 9.9%, and 12.4%, respectively, were as follows: operation (71, 84%), mortality (36, 93%), and intensive care unit admission (25, 94%)., Conclusion: In patients with blunt hepatic injury, the Cavalieri principle of stereology can easily be added to the CT slices to calculate PIAH. This method is repeatable in other institutions and can be used as a guide to predict outcomes. It is suitable for a universal parameter to measure intra-abdominal fluid in blunt injury. PIAH has low sensitivity but high specificity to predict intensive care unit admission and mortality in cases of blunt hepatic injury in adults. Its specificity in predicting the need for operation is better than that of the anatomic liver injury grading systems in computerized tomography., Level of Evidence: Prognostic study, level III.

- Abstract
Objective: In this study, anticancer effects of mirtazapine on rats were investigated in an adenocarcinoma model induced by N-methyl-N-nitro-N-nitrosoguanidine (MNNG) and compared with those of cisplatin., Materials and Methods: For this purpose, 10 mg/kg doses of mirtazapine were administered orally to one group of rats, while 1 mg/kg doses of cisplatin were administered intraperitoneally to another group. At 1 hour after administration, 200 mg/kg doses of MNNG were given orally to both groups. MNNG administration was repeated once every 10 days through 3 months, after which period, gastric tissue was taken and pathologically evaluated., Results: Mirtazapine prevented adenocarcinoma induction by MNNG in rats to a greater extent than cisplatin. Some of the rats receiving cisplatin demonstrated severe dysplasia in gastric samples and others exhibited mild dysplasia. Rats given mirtazapine were not observed to suffer severe dysplasia, only mild dysplasia being observed., Conclusion: For adenocarcinoma induced by MNNG on rats, mirtazapine was determined more effective than cisplatin. In order to make statement about mechanism of anticancer activity of mirtazapine, wider studies are required.

- Abstract
Background: The aim of this prospective study was therefore to evaluate the diagnostic value of preoperative serum High Mobility Group Box Protein-1 (HMGB-1) levels in patients with Acute Appendicitis (AA) who show normal white blood cell count (WBC) counts., Method: Our study was carried out from October 2010 through November 2010 and included 20 healthy control group participants and 60 patients who presented at the emergency department of Erzurum Training and Research Hospital in Turkey with acute abdominal pain complaints, who were pathologically diagnosed with AA after laparotomy, and who agreed to participate in the study., Results: Of the 60 patients who underwent appendectomies, 36 were male and 24 were female, and of the healthy group, 12 were male and 8 female. The age averages of the patients in Groups 1, 2 and 3 were, respectively, 31.3+15.4, 34.0+16.3 and 31.0+13.1 years. The WBC averages of Groups 1, 2 and 3 were, respectively, 7.41+2.02 (x10⁹/L), 15.71+2.85 (x10⁹/L) and 8.51+1.84 (x10⁹/L). The HMGB-1 levels for Groups 1 (healthy persons), 2 (AA patients with high WBC counts ) and 3 (AA patients with normal WBC counts) were, respectively, 21.71±11.36, 37.28+13.37 and 36.5±17.73 ng/ml. The average HMGB-1 level of the patients with AA was 36.92±15.43 ng/ml while the average HMGB-1 value of the healthy group was 21.71±11.36 ng/ml., Conclusion: The significantly higher levels of HMGB-1 in AA patients compared to healthy persons infer that HMGB-1 might be useful in the diagnosis of AA. Use of HMGB-1, especially in patients with normal WBC counts, will reduce the number of unnecessary explorations.
