Background: Urinary tract infections (UTIs) are important causes of morbidity and mortality in patients with spinal cord injury and 22% of patients with acute spinal cord injury develop UTI during the first 50 days. Objectives: The aim of this study was to determine the prevalence, etiologic agents and risk factors for asymptomatic bacteriuria and symptomatic urinary tract infections in patients with spinal cord injury. Patients and Methods: This was a prospective investigation of spinal cord injury patients with asymptomatic bacteriuria and symptomatic urinary tract infections in Baskent University Medical Faculty Ayas Rehabilitation Center and Ankara Physical Therapy and Rehabilitation Center between January 2008 and December 2010. The demographic status, clinical and laboratory findings of 93 patients with spinal cord injury were analyzed in order to determine the risk factors for asymptomatic or symptomatic bacteriuria Results: Sixty three (67.7%) of 93 patients had asymptomatic bacteriuria and 21 (22.6%) had symptomatic urinary tract infection. Assessment of the frequency of urinary bladder emptying methods revealed that 57 (61.3%) of 93 patients employed permanent catheters and 24 (25.8%) employed clean intermittent catheterization. One hundred and thirty-five (48.0%) of 281 strains isolated form asymptomatic bacteriuria attacks and 16 (66.6%) of 24 strains isolated from symptomatic urinary tract infection attacks, totaling 151 strains, had multidrug resistance (P > 0.05). One hundred (70.4%) of 142 Escherichia coli strains and 19 (34.5%) of 55 Klebsiella spp strains proliferated in patients with asymptomatic bacteriuria; 8 (80%) of 10 E. coli strains and 4 (80%) of 5 Klebsiella spp. strains were multidrug resistant. Conclusions: The most common infectious episode among spinal cord injury patients was found to be urinary tract ınfection. E. coli was the most common microorganism isolated from urine samples. Antibiotic use in the previous 2 weeks or 3 months, hospitalization during the last one-year and previous diagnosis of urinary tract ınfection were the risk factors identified for the development of infections with multi-drug resistant isolates. Urinary catheterization was found to be the only independent risk factor contributing to symptomatic urinary tract infection.

Background: The level of platelet volume (MPV) has been reported to be a laboratory marker in inflammatory cases. Objectives: The aim of this study was to seek whether MPV has a role in the diagnosis of acute appendicitis. It was also aimed to show the relationship of MPV with leukocyte count and C-reactive protein (CRP) level. Materials and Methods: This study was conducted via retrospective assessment of the hospital records of the adult patients who were operated for acute appendicitis between January 2010 and December 2012 and had a pathology report that confirmed the diagnosis of acute appendicitis. The patients in the control group were selected from healthy adults of similar age who applied to check-up clinic. The number of essential cases was defined by performing power analysis. Age, gender, leukocyte count, CRP, and MPV values were recorded. This study is a case controlled retrospective clinical study. Results: A total of 503 patients in the acute appendicitis group and 121 patients in the control group were included, making up a total of 624 subjects. The median MPV levels were 7.92 ± 1.68 fL in the acute appendicitis group, while 7.43 ± 1.34 fL in the control group. CRP, leukocyte count, and MPV level were significantly higher in the acute appendicitis group (P < 0.001). MPV, leukocyte count, and CRP had a sensitivity and specificity of 66% and 51%; 91% and 74%; and 97% and 41%, respectively. No correlation was found between MPV, CRP, and leukocyte count. Conclusions: MPV level was higher in patients with acute appendicitis. MPV may guide the diagnostic process of acute appendicitis. However, we detected that the sensitivity and specificity of leukocyte count and CRP were superior to those of MPV in the diagnosis of acute appendicitis.

PurposeThe aim of this study was to seek whether red cell distribution width (RDW) has a role in the diagnosis of acute appendicitis. It was also aimed to show the relationship of RDW with leukocyte count and C-reactive protein (CRP) level.MethodsThis study was conducted via retrospective assessment of the hospital records of the adult patients who were operated for acute appendicitis between January 2010 and February 2013 and had a pathology report that confirmed the diagnosis of acute appendicitis. The patients in the control group were selected from healthy adults of similar age who applied to check-up clinic. Age, gender, leukocyte count, CRP, and RDW values were recorded. This study is a case controlled retrospective clinical study.ResultsA total of 590 patients in the acute appendicitis group and 121 patients in the control group were included, making up a total of 711 subjects. The mean RDW levels were 15.4 ± 1.5% in the acute appendicitis group, while 15.9 ± 1.4% in the control group. CRP, leukocyte count were significantly higher in the acute appendicitis group, and RDW level were significantly lower in the acute appendicitis group (p < 0.001, p < 0.001, p = 0.001, respectively). RDW, leukocyte count, and CRP had a sensitivity and specificity of 47% and 67%; 91% and 74%; and 97% and 41%, respectively in acute appendicitis. RDW was not correlated with CRP and leukocyte levels. However, we found a correlation between CRP and leukocyte levels.ConclusionRDW level was lower in patients with acute appendicitis. The magnitude of difference in RDW seen between acute appendicitis and controls was so slight as to be of no utility in diagnostic testing.

Background and Aim: Tigecycline is a semi-synthetic tetracycline with activity against most multidrug-resistant (MDR) bacteria. Methods: We studied in vitro activity of tigecycline by agar dilution (AD) and Etest methods to evaluate their correlation. The study included 206 isolates of extended-spectrum β-lactamase (ESBL)-producing Escherichia coli, Klebsiella pneumoniae and MDR Acinetobacter baumannii recovered from blood cultures of patients of Baskent University between 2008 and 2010. Results: ESBL-producing E. coli had MIC50/MIC90 values of 0.5/0.5 µg/ml by AD and 0.25/0.5 µg/ml by Etest. ESBL-producing K. pneumoniae had MIC50/MIC90 values of 1/2 µg/ml by AD and 0.75/2 µg/ml by Etest, whereas MDR A. baumannii had MIC50/MIC90 values of 4/4 µg/ml by AD and 2/4 µg/ml by Etest. The correlation between AD and Etest was weak for ESBL-producing E. coli and strong for ESBL-producing K. pneumoniae and MDR A. baumannii. Tigecycline MIC values for ESBL-producing E. coli were lower than the tigecycline concentration, while they were higher than the concentrations attainable by treatment doses for A. baumannii. Conclusion: Tigecycline is an appropriate agent in the treatment of E. coli bacteremia, but it is not for treating A. baumannii bacteremia. Tigecycline could be used for K. pneumoniae bacteremia treatment after determining its MIC value. Determining the MIC value by gold-standard methods is more appropriate due to the correlation between Etest and AD at high MIC values.

The urinary tract is the most common site of bacterial infections in renal transplant recipients. The management of urinary tract infections (UTI) in renal transplant recipients is becoming more difficult because of drug-resistant bacteria. The antimicrobial susceptibilities of uropathogen bacteria isolated from 398 patients who underwent renal transplantation between 2007 and 2011 were obtained from medical records. At least 1 UTI episode was diagnosed in 172 (43.2%) patients. Among the 703 bacteria isolated from these patients, Exherichia coli the most common pathogen, was isolated from 407/703 episodes (57.8%). Ciprofloxacin, co-trimoxazole, ceftriaxone, and gentamicin resistance rates were 59.4%, 85.7%, 40.7%, and 36.6%, respectively. Ninty six of 407 E. coli isolates (23.5%) were ESBL positive. Analysis of resistance rates in our center demonstrated ciprofloxacin resistance rate in uropathogenic E. coli to have increased gradually from 30.4% in 2003, 41.3% in 2007, and 59.4% in 2012. Instutional data regarding the etiologic agents and antimicrobial susceptibility results are important for proper management of patients with UTI.

Objective To compare the serum mean platelet volume (MPV) in patients with testicular torsion and healthy control subjects. Methods This retrospective study compared clinical and demographic data from patients who underwent surgery for testicular torsion and healthy controls. Testicular torsion was diagnosed with a physical examination and Doppler ultrasonography. Age, leukocyte count, platelet count and MPV were recorded for all participants. Results A total of 50 patients with testicular torsion and 51 healthy control subjects were enrolled. There was no significant difference in age and platelet count between the two groups. Patients with testicular torsion had a significantly higher leukocyte count and MPV, compared with controls. According to receiver operating characteristic curve analysis performed for the prediction of testicular torsion, the best cut-off point for MPV was 7.7 fl (sensitivity 62%, specificity 96%), and the best cut-off point for leukocyte count was 9.5 × 109/l (sensitivity 58%, specificity 80%). Conclusions The MPV may be useful as an ancillary test for the diagnosis of testicular torsion. Further studies are needed in order to confirm these preliminary results.

Although there is no other underlying disease, women can sometimes experience rare and serious diseases such as ovarian vein thrombosis (OVT) and renal vein thrombosis (RVT) after giving birth. The widespread development of thrombosis is treated for the first time in this study. Stasis, coagulation factor abnormalities, and intimal damage to the venous thrombosis risk can increase during pregnancy. It was mentioned that it diagnoses an abnormality in the hypercoagulability half of women with OVT. Despite the hypercoagulant abnormality observed in pregnant women, it was very unusual that the renal vein thrombosis led to this complication. It can lead to severe complication of OVT which can even cause death. It was the first time that the renal vein and ovarian vein thrombosis were observed in the postpartum period, and there was no coagulation abnormality. It is known that the thrombus in the postpartum period can be observed with the fever of unknown origin. The problematic, but rarely observed, postpartum disease such as ovarian venous thrombosis (OVT) is generally observed in the right ovarian vein. In this disease, avoiding the resulting laparotomy heparin and intravenous antibiotics is best solution for the patient. If it is to be noted a fever for unknown reasons, that it be thrombosis.

Background: Brucellosis is an inflammatory disease which may infect any organs or systems in the body. Mean Platelet Volume (MPV) is one of the most frequently used surrogate markers of platelet function. It reveals the presence of disease activity in many inflammatory diseases. Red blood cell distribution width (RDW) is a parameter that measures variation in red blood cell size or red blood cell volume. Its predictive value approves inflammatory and infectious diseases. Objectives: The current study aimed to determine the assessment levels of red blood cell distribution in cases with acute brucellosis. Patients and Methods: The current study investigated whether MPV and RDW played any roles in acute brucellosis diagnosis. The study was conducted from 2008 to 2014 through prospective examination of the inflammatory markers found in adult patients with acute brucellosis. Results: The follow-up within the year after treatment was examined. The values of age, gender, leukocyte count, C-reactive protein, RDW and MPV were recorded. The study included 351 subjects, 250 of them in the acute brucellosis group and 101 in the control group. The mean MPV levels were 7.64 ± 1.30 fL, and 7.67 ± 1.29 fL in the acute brucellosis and control groups, respectively (P > 0.05). The mean CRP levels were 32.57 ± 53.20 mg/dL, and 4.81 ± 4.89 mg/dL in the acute brucellosis and control groups, respectively (P < 0.05). There was no statistically significant difference between the two groups regarding the RDW level and the mean leukocyte count (P > 0.05). Conclusions: While the CRP value was in patients with acute brucellosis in the current study, the MPV, RDW and leukocyte counts were within the normal range. CRP value remains the most valuable inflammatory marker in cases of acute brucellosis.

INTRODUCTION In this study, we examined the effects of Brucella infection on endothelial dysfunction. Flow-mediated dilatation (FMD) measurement is indicator of the endothelial function, and abnormal values indicating endothelial dysfunction are accepted as the first stage of atherosclerosis. METHODOLOGY Twenty-four patients who had been treated for acute brucellosis two years before, and who had had no relapses in the follow-up, were prospectively included in the study, along with 30 healthy individuals in the control group. RESULTS While the highly sensitive C-reactive protein (hs-CRP) value was 2.42 ± 1.45 in the patient group, it was 1.72 ± 0.61 in the control group (p = 0.025). While the FMD value was 3.50 ± 1.58 in the patient group, it was 5.88 ± 1.88 in the control group (p < 0.001). While the percentage increase in FMD was 9.88 ± 4.92 in the patient group, it was 17.49 ± 6.3 in the control group (p < 0.001). It was observed that FMD value, the percentage increase in FMD, and basal radius were correlated with hs-CRP (r = -0.644, p < 0.001; r = - 0.558, p = 0.002; r = 0.444, p = 0.018, respectively). The carotid artery intima media thickness (IMT) value was found to be 0.61 ± 0.17 in the patient group and 0.49 ± 0.12 in the control group (p = 0.004). CONCLUSIONS The abnormal FMD and IMT values observed in brucellosis patients might be an indicator of more frequent arterial dysfunction, increased cardiovascular risk, and atherosclerosis.

The breast is as aesthetically important as it is physiologically. Physicians and women have practiced various methods for breast aesthetics and augmentation. We report a female veterinarian who injected fish oil into her breast, which led to inflammation and necrosis of breast tissue. When all medical therapies failed, bilateral subcutaneous mastectomy was performed. We did not find a case in the literature where fish oil had been used for breast augmentation. However, we did find that many agents have been injected for breast augmentation, the results of which were tragic, just as the case presented herein.
