OBJECTIVE: This study evaluated the effects of sibutramine on intraocular pressure (IOP) and body-mass index (BMI). METHODS: Thirty obese females (body-mass index>30 kg/m2) treated with sibustramine (10 mg/day) plus plus diet restriction for 3 months were included in the study. IOP, BMI, and blood biochemical parameters were measured at the beginning and end of the treatment. Results were evaluated statistically by paired t-test, analysis of variance, and least-significant difference test. RESULTS: A statistically significant decrease was observed in the mean body-mas index (p<0.001) ans serum triglyceride (p<0.001), while a statistically significant increase was observed in IOP (p=0.54). CONCLUSION: While sibustramine provided an effective means for weight loss, it caused a slight increase in IOP, although this was not statistically significant. Nevertheless, it is prudent to monitor IOP in selected obese patients treated with sibustramine.

BACKGROUND: Visfatin is an adipokine produced by visceral adipose tissue and has insulin-mimicking effects. Fetuin-A is a hepatic secretory protein that binds the insulin receptor and inhibits insulin action both in vivo and in vitro. The authors of the present study aimed to investigate the levels of serum visfatin and fetuin-A and their correlation with hemoglobin A1c (HbA1c) and urine albumin levels in patients with type 2 diabetes mellitus (T2DM). METHODS: A total of 40 obese patients with T2DM (11 males and 29 females; age, 54.47+/-10.83 years and 23 obese nondiabetic controls (8 males and 15 females; age, 53.04+/-11.33 years) were included in the study. Age, sex, and body mass index were similar in the 2 groups. Serum visfatin and fetuin-A levels were measured by enzyme-linked immunosorbent assay. HbA1c and urine albumin levels were measured by high performance liquid chromatography and nephelometric method, respectively. RESULTS: Serum levels of visfatin in patients with T2DM (4.03+/-2.44 ng/mL) were similar to the control group (3.65+/-3.02 ng/mL). Serum fetuin-A levels were significantly lower in patients with T2DM than the controls (298.75+/-78.86 and 430.73+/-94.46 microg/mL, respectively). HbA1c levels were significantly higher in the T2DM group compared with controls (7.33+/-1.32 and 5.44+/-0.84%, respectively). Correlations between visfatin, fetuin-A and HbA1c levels were not observed. CONCLUSION: The present study suggests fetuin-A may play a role in the pathogenesis of T2DM.

Objectives: This study was conducted to evaluate the effects of traditional and contracted endodontic cavity (TEC and CEC) preparation with the use of Reciproc Blue (RPC B) and One Curve (OC) single-file systems on the amount of apical debris extrusion in mandibular first molar root canals. Materials and Methods: Eighty extracted mandibular first molar teeth were randomly assigned to 4 groups (n = 20) according to the endodontic access cavity shape and the single file system used for root canal preparation (reciprocating motion with the RCP B and rotary motion with the OC): TEC-RPC B, TEC-OC, CEC-RPC B, and CEC-OC. The apically extruded debris during preparation was collected in Eppendorf tubes. The amount of extruded debris was quantified by subtracting the weight of the empty tubes from the weight of the Eppendorf tubes containing the debris. Data were analyzed using 1-way analysis of variance with the Tukey post hoc test. The level of significance was set at p < 0.05. Results: The CEC-RPC B group showed more apical debris extrusion than the TEC-OC and CEC-OC groups (p < 0.05). There were no statistically significant differences in the amount of apical debris extrusion among the TEC-OC, CEC-OC, and TEC-RPC B groups. Conclusions RPC B caused more apical debris extrusion in the CEC groups than did the OC single-file system. Therefore, it is suggested that the RPC B file should be used carefully in teeth with a CEC.

Objective To investigate the antimicrobial susceptibility of 97 clinical Staphylococcus aureus (S. aureus) strains against 14 antimicrobials and corresponding resistance mechanisms. Methods The antimicrobial susceptibility of the isolates was determined using a disk diffusion method and antimicrobial resistance genes were screened by polymerase chain reaction. Mutations responsible for ciprofloxacin and rifampicin resistance were investigated by polymerase chain reaction and DNA sequencing. Results All isolates were found to be susceptible to vancomycin. Various rates of resistance to penicillin (83.5%), ampicillin (77.3%), erythromycin (63.9%), tetracycline (16.5%), amoxicillin/clavulanic acid (16.5%), ciprofloxacin (15.5%), trimethoprim/sulfamethoxazole (15.5%), oxacillin (13.4%), fusidic acid (12.4%), rifampin (6.2%), clindamycin (6.2%), gentamicin (6.2%) and mupirocin (5.2%) were determined. In addition, different combinations of resistance genes were identified among resistant isolates. Ciprofloxacin resistant isolates had mutations in codon 84 (Ser84Leu) and 106 (Gly106Asp) in the gyrA gene. Mutations in grlA were mostly related to Ser80Phe substitution. Leu466Ser mutation in the rpoB gene was detected in all rifampin resistant isolates. All methicillin resistant S. aureus isolates were SCCmec type V. Conclusions In conclusion, it was determined that the isolates were resistant to different classes of antimicrobials at varying rates and resistance was mediated by different genetic mechanisms. Therefore, continuous monitoring of resistance in S. aureus strains is necessary to control their resistance for clinically important antimicrobials.

PURPOSE: Single incision laparoscopic cholecystectomy (SILC) has become a more frequently performed method for benign gallbladder diseases all over the world. The effects of SILC technique on oxidative stress have not been well documented. The aim of this study was to evaluate the effect of laparoscopic cholecystectomy techniques on systemic oxidative stress by using ischemia modified albumin (IMA). METHODS: In total, 70 patients who had been diagnosed with benign gallbladder pathology were enrolled for this prospective study. Twenty-one patients underwent SILC and 49 patients underwent laparoscopic cholecystectomy (LC). All operations were performed under a standard anesthesia protocol. Serum IMA levels were analysed before operation, 45 minutes and 24 hours after operation. RESULTS: Demographics and preoperative characteristics of the patients were similiar in each group. The mean duration of operation was 37.5 ± 12.5 and 44.6 ± 14.3 minutes in LC and SILC group, respectively. In both groups, there was no statistically significant difference in hospital stay, operative time, or conversion to open surgery. Operative technique did not effect the 45th minute and 24th hour IMA levels. However, prolonged operative time (>30 minutes) caused an early increase in the level of IMA. Twenty-fourth hour IMA levels were not different. CONCLUSION: SILC is an effective and safe surgical prosedure for benign gallbladder diseases. Independent of the surgical technique for cholecystectomy, the prolonged operative time could increase the tissue ischemia.

AIM:To determine whether there was a significant relationship between eye iris color with axial length, intraocular pressure, retinal nerve fiber layer (RNFL) thickness, macular thickness and choroidal thickness.METHODS:A prospective cross-sectional study involving 92 eyes of 92 healthy volunteers.These were divided into dark colored-eye (DCE) and light-colored eye (LCE) groups according to iris color.The RNFL and macular thicknesses were analysed with standard optical coherence tomography (OCT) protocol while choroidal thickness was analysed with electronic data interchange (EDI) protocol in all subjects.Choroidal thickness was measured at the fovea, 1500 μm nasal and 1500 μm temporal to the fovea in a horizontal section.RESULTS:Of the 92 eyes included, 62 (67.4%) were dark-colored while 30 (32.6%) were light-colored.The mean age was 29.22±5.86y in the subjects with DCE and 28.86±6.50y in those with LCE.No significant difference was detected in mean age, axial length, macular thickness, choroidal thickness and intraocular pressure (IOP) between the groups (P>0.05).However, RNFL thicknesses varied depending on the quadrant measured, and were lower in both global and the nasal and temporal quadrants for individuals with LCE (P≤0.022).CONCLUSION:No significant differences were found in IOP, macular thickness and choroid thickness between individuals with DCE and LCE.Meanwhile, the RNFL thickness is lower.

BACKGROUND:This study aimed to compare pantoprazole, a proton-pomp inhibitors (PPIs), and ranitidine, a H2 receptor antagonists (H2RA), in ceasing dyspeptic symptoms in the emergency department (ED). METHODS:This randomized, double-blinded study compared the effectiveness of 50 mg ranitidine (Ulcuran?) and 40 mg pantoprazole (Pantpas?), given in a 100 mL saline solution by an intravenous rapid infusion within 2–4 minutes in patients with dyspepsia presented to the ED. Pain intensity was measured at baseline, 30 and 60 minutes after the drug administration. RESULTS:A total of 72 patients were eligible for the study. Of these patients, 2 were excluded from the study because the initial visual analogue scale (VAS) scores were under 20 mm and 4 were excluded from the statistical analysis because of being diagnosed as having other causes of epigastric pain despite being allocated to one of the study groups. Thirty-three patients in the pantoprazole group and 33 patients in the ranitidine group were analyzed ultimately. The mean age of the patients was 36.6±15 years, and 26 (39.4％) patients were male. Both of the groups reduced pain effectively at 30 [27.6±28 (18 to 37) vs. 28.3±23 (20 to 37), respectively] and 60 minutes [39.6±39 (26 to 53) vs. 42.3±25 (33 to 51), respectively]. There were 13 (39.4％) patients in the pantoprazole group and 8 (24.2％) patients in the ranitidine group who required additional drug at the end of the study (P=0.186). CONCLUSION:Intravenous pantoprazole and ranitidine are not superior to each other in ceasing dyspeptic symptoms at 30 and 60 minutes in the ED.
