Abstract
OBJECTIVE Prediabetes accompanied by metabolic syndrome accelerates the process leading to diabetes and causes an increase in complications. The current study aimed to investigate the clinical conditions accompanying prediabetes and the effect of the association of metabolic syndrome on clinical outcomes in prediabetics. SUBJECTS AND METHODS This cross-sectional study was conducted with 88 prediabetic individuals between November 2022 and January 2023. Prediabetes was diagnosed using the American Diabetes Association (ADA) criteria, and metabolic syndrome was diagnosed using the International Diabetes Federation criteria. Clinical history, physical examination and laboratory tests of the participants were recorded. RESULTS Metabolic syndrome (MetS) was present in 69 of 88 prediabetic patients included in the study (78.4%). Hypertension (p=0.019), abdominal obesity (p<0.001), low-density lipoprotein (LDL) elevation (p=0.006), and dyslipidemia (p=0.020) were detected more frequently in prediabetic individuals accompanied by MetS. Median values of waist circumference (p=0.020), systolic blood pressure (p=0.021), triglyceride (p<0.001), LDL (p=0.003) and postprandial blood sugar (p=0.049) in prediabetics accompanied by MetS were statistically significant. It was higher than those without MetS. The median Vit-D level of prediabetics without MetS was higher than those with MetS (p=0.049). The median creatinine value of prediabetics without MetS was higher than that of prediabetics with MetS (p=0.049). CONCLUSIONS Hypertension, dyslipidemia, abdominal obesity, and metabolic obesity increased in the coexistence of prediabetes and MetS. At the same time, the coexistence of prediabetes and MetS was associated with higher systolic blood pressure, postprandial blood sugar, and LDL levels. Prediabetic individuals accompanied by MetS are at greater metabolic risk.

Short- and mid-term results of diode laser treatment in pilonidal sinus disease and the role of endoscopic camera use on outcomes. Tech Coloproctol 2023; 27:921-928. [PMID: 37356014 DOI: 10.1007/s10151-023-02831-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Accepted: 06/01/2023] [Indexed: 06/27/2023]
Abstract
PURPOSE Nowadays, surgical treatment of pilonidal sinus disease (PSD) with novel techniques is a topic of interest since conventional methods are associated with longer return to daily life and higher complication and recurrence rates. Recently, use of laser as a minimally invasive approach has become popular in the surgical treatment of PSD. In this study, we analyze the short- and mid-term results after laser treatment and the effect of endoscopic camera use on outcomes. METHODS A total of 106 patients with PSD who underwent laser treatment between November 2017 and September 2021 were included in this study. All patients were treated with a 1470-nm diode laser. Endoscopic camera was used in 73 patients and results of these were compared with those in whom camera was not used. Follow-up period was determined as a minimum of 1 year. Data were analyzed retrospectively. RESULTS There were 80 (75%) male and 26 female patients. The median age was 26 (range 13-50) years. On the first postoperative day, 26 (26.5%) patients did not have any pain and 42(42.8%) patients reported low-grade pain. The mean time to return to daily life was 4.5 ± 5.5 (median 2, range 1-30) days. The complication rate was 10.4%. Eighty-six (87.8%) patients completely recovered and the mean complete recovery time was 27.4 ± 15.9 days. The patient satisfaction rate was 99.0%. The recurrence rate was 11.0%. Neither history of previous surgery nor abscess was associated with recurrence. Use of an endoscopic camera had no effect on postoperative pain, complete recovery, complications, patient satisfaction, and recurrence (p < 0.05). CONCLUSION Laser treatment for PSD is a promising approach with the advantages of less postoperative pain, early return to daily life, high patient satisfaction, and acceptable complication and recurrence rates. Nevertheless, further studies are needed to investigate the role of endoscopic camera use in this procedure since its possible advantages could not be clarified.

Abstract
Background In early-stage lip cancer, spread to cervical lymph nodes is extremely rare. Elective neck treatment options include suprahyoid or supraomohyoid neck dissection, sentinel lymph node biopsy, or close follow-up. Aim: In this study, our aim was to investigate the effect of elective surgery on survival in patients operated for early-stage lip cancer. Methods Patients who underwent surgical treatment for lower lip squamous cell carcinoma between 2005 and 2020 were retrospectively analyzed. Age, gender, neck dissection status (yes/no), clinical and pathological T stage of the tumor, grade, and perineural invasion were recorded and 3-year and 5-year overall (OS) and disease-free survival (DFS) rates were estimated. Results Thirty patients were included: 20 patients had pT1 and 10 patients had pT2 tumors. Neck dissection was performed in 13 patients. The 5-year OS rate was 90.9% and 87.8% with and without dissection, respectively. Neck dissection did not appear to affect OS (P = 0.534) in these patients. The 5-year DFS rate was 96.4% in the overall group, while it was 91.7% and 100% in patients who did or did not undergo neck dissection, respectively (P = 0.756). Discussion Patients with or without neck dissection did not differ significantly in terms of OS and DFS. Watchful waiting with regular ultrasound imaging of the neck in patients with T1 and T2 lip tumors may be an appropriate therapeutic option.

Abstract
OBJECTIVE Cerebrovascular diseases (CVDs) remain an important public health issue due to the increasing number of deaths worldwide. Changes in the synthesis and release of peptides in CVDs may play an important role in elucidating the physiopathology of the disease. Therefore, this study was to investigate the fate of maresin-1 (MaR-1), subfatin (SUB), asprosin (ASP), and alamandine (ALA) levels in patients with cerebral infarction (CI), intracranial hemorrhage (ICH), subarachnoid hemorrhage (SAH) evaluated within the scope of CVDs, and voluntary healthy controls. PATIENTS AND METHODS The study participants were divided into 4 groups: CI patients, ICH patients, SAH patients, and healthy volunteers. The diagnosis of CVDs was made based on the National Institutes of Health Stroke Scale (NIHSS), Intracerebral Hemorrhage Score (ICHS), Botterel-Hunt-Hess Scale (BHHS), and cranial computed tomography (CT). The levels of MaR-1 (ng/mL), SUB (ng/mL), ASP (ng/mL), and ALA (pg/mL) in the blood samples collected from the participants were studied using the ELISA method. Other parameters included in the study were obtained from the patient records of our hospital. RESULTS The comparison of MaR-1 [(control 1.38 ± 0.14), SAH (0.98 ± 0.087), CI (0.67 ± 0.04), ICH (0.51 ± 0.03)], SUB [(control (13.2 ± 1.4), SAH (10.1 ± 1.2), CI (7.9 ± 0.8), ICH (5.8 ± 0.5)], and ALA [(control (67.2 ± 7.9), SAH (58.2 ± 4.3), CI (42.1 ± 3.7), and ICH (34.2 ±3.9)] values revealed a significant decrease compared to the control values. The comparison of the ASP values of SAH, CI, and ICH patients and control values (11.6 ± 1.2) showed significantly higher asprosin values in SAH (13.8 ± 1.1), CI (15.4 ± 1.2) and ICH (28.9 ± 2.8) patients. Similarly, systolic blood pressure (SBP), diastolic blood pressure (DBP), and glucose levels of CKD patients were also high. CONCLUSIONS Decreased MaR-1, SUB, ALA and increased ASP compared to the control values may play a role in the physiopathology of these diseases. MaR-1, SUB, ALA, and ASP differences between SAH, CI and ICH patients may also guide clinicians along with SBP, DBP and glucose values.

Abstract
OBJECTIVE Several studies have previously shown that some small leucine-rich proteoglycans (SLRPs) are associated with atherosclerotic plaque. We aim to investigate the relationship between circulating lumican levels and the severity of coronary artery disease (CAD). PATIENTS AND METHODS This study included 255 consecutive patients who underwent coronary angiography for stable angina pectoris. All demographic and clinical data were collected prospectively. The severity of CAD was assessed based on the Gensini score and a value >40 was defined as advanced CAD. RESULTS Eighty-eight patients were in the advanced CAD group; these are older and the frequency of diabetes mellitus, cerebrovascular accidents, reduced ejection fraction (EF), left atrium diameter was higher. Serum lumican levels were found as higher in advanced CAD group (0.4 ng/ml vs. 0.6 ng/ml, respectively, p<0.001). When the Gensini score increased, a statistically significant increase was observed in lumican levels with a good correlation (r=0.556 and p<0.001). In multivariate analysis, diabetes mellitus, EF and lumican were predictive for advanced CAD. Lumican level predicts CAD seriousness with a sensitivity rate of 64%, specificity rate of 65%. CONCLUSIONS In this study, we reveal a relationship between serum lumican levels and CAD severity. More research is warranted to determine the mechanism and prognostic values of lumican in the atherosclerosis.

Abstract
OBJECTIVE Diabetes is an important endocrinological disease that has an increasing incidence in the world and affects all biological tissues including testicles. Therefore, this study aimed to reveal the histological and biochemical effects of vitamin D on irisin, apoptosis, total antioxidant status (TAS), and total oxidant status (TOS) in testicular tissues of rats with experimental diabetes. MATERIALS AND METHODS 41 male Wistar rats, 8-10 weeks old, weighing between 200-220 g, were included in the study as the following groups: control group (n=7; no treatment), sham group [only sodium citrate buffer (SCB)] [n=7; single dose 0.1 Molar (M) SCB given intraperitoneally (i.p)], vitamin D group (n=7; 50 IU/day given orally), diabetes group [n=10; single dose 50 mg/kg Streptozotocin (STZ) dissolved in 0.1 M SCB and given i.p (tail vein blood glucose level above 250 mg/dl after 72 hours)] and diabetes+vitamin D group [n=10, single dose 50 mg/kg STZ, dissolved in 0.1 M SCB and given i.p (tail vein blood glucose level above 250 mg/dl after 72 hours) and when diabetes occurs, oral vitamin D administration of 50 IU/day)]. At the end of the 8 weeks experiment, blood was drawn from the tail vein of all rats, they were sacrificed and testicular tissues were taken. While the amount of irisin in the blood and testicular tissue supernatants was analyzed with the Enzyme-Linked Immunosorbent Assay (ELISA) method, TAS and TOS measurements were analyzed with the REL method, testicular tissues were analyzed histopathologically, immunohistochemically, and with the TUNEL method. RESULTS When the diabetes group was compared with the control and sham groups, it was reported that the amounts of blood and tissue supernatant irisin and TAS significantly decreased and the TOS was significantly increased; a statistically significant increase in irisin and TAS of blood and tissue supernatants and a significant decrease in TOS were detected when diabetes+vitamin D and diabetes groups were compared among themselves. Similar results were obtained in the immunohistochemical studies. Tissue expressions of irisin decreased in the diabetes group compared to the control and sham groups, while the application of vitamin D increased the tissue expressions of irisin. Additionally, when the numbers of apoptotic cells were compared, it was reported that apoptotic cells in the diabetes group increased significantly compared to the control and sham groups, and vitamin D administration significantly decreased the number of apoptotic cells. CONCLUSIONS Taken together, vitamin D administration to diabetic rats decreased the number of apoptotic cells and increased the amount of irisin. Vitamin D had an effective role in maintaining the physiological integrity of rat testicular tissues, so vitamin D may be a potent agent to be used in the treatment of diabetes in the future.

Abstract
OBJECTIVE In this study, we sought to investigate the effects of energy drink supplementation and treadmill exercise on the levels of free radicals, antioxidants, Angtpl8, Elabela, and lipid metabolism in rats. MATERIALS AND METHODS A total of 28 male Wistar albino rats (4 weeks old, 101.96 ± 9.75 g) were included in the study. The rats were randomly divided into four equal groups: control, exercise, supplement, and exercise+supplement groups. At the end of the study, the rats were decapitated, and blood samples were tested for levels of Angptl-8, ghrelin, leptin, irisin, SOD, CAT, TBARS, total oxidant status, and total antioxidant status using enzyme-linked immunosorbent assay. Levels of blood lipids including triglycerides, total cholesterol, HDL-C, and LDL-C were studied using spectrophotometric method in an auto analyzer. RESULTS Statistical analysis showed statistical significance in TBARS, LDL-C, irisin, Angptl-8, and Elabela levels of the exercise group; SOD and HDL-C levels of the supplement+exercise group; and total cholesterol levels in the supplement group (p < 0.05). Although there were differences between the groups in leptin, ghrelin, and CAT levels, they were not statistically significant (p > 0.05). CONCLUSIONS As a result, it can be argued that treadmill exercise is important in regulating lipid metabolism and stimulating peptide hormones and receptors. Furthermore, consuming energy drinks without performing exercise or physical activity increases fat stores, and such increases in the critical organs and tissues may pose a threat to the body.

Abstract
OBJECTIVE Gestational diabetes mellitus (GDM) is a type of diabetes that affects from 3.8% to 6.9% of pregnancies worldwide, causing significant mortality and unfavorable obstetric outcomes, such as delivery trauma and macrosomia risk. The fundamental processes of this metabolic disorder that first appeared during pregnancy are still unknown. Tissue hormones, particularly adipokines, have aided in understanding the pathophysiology of numerous disorders in recent years. This study aims to determine if Apelin-13 (APLN-13), Apelin-36 (APLN-36), Elabela (ELA), and nitric oxide (NO) molecules have all a part in the pathophysiology of GDM. PATIENTS AND METHODS The study included 30 pregnant control women and 30 pregnant women who had been diagnosed with GDM in the second trimester and whose body mass index and age were compatible with each other. Blood samples were collected from 60 participants during the second trimester (30 control pregnant women and 30 GDM pregnant women) and postpartum (17 controls vs. 14 GDM). In these blood samples, the amounts of APLN-13, APLN-36, ELA, and NO were studied using the ELISA method. In addition, the participants' glucose, lipid profiles, and other parameters were obtained from the hospital record files. At postpartum, 29 pregnant women (13 control and 16 pregnant women with GDM) dropped out of the study without explanation. RESULTS In the second trimester and postpartum plasma of mothers with GDM, APLN-13, APLN-36, NO, and ELA molecules were found to be significantly higher (< 0.05), compared to those of the control mothers, while APLN-13, APLN-36, NO values were significantly lower (0.05). While APLN-13, APLN-36, NO amounts in mothers with GDM were positively correlated with glucose amounts, they were negatively correlated with ELA amounts. Similarly, the triglyceride amounts in mothers with GDM were positively correlated with APLN-13, APLN-36 and NO, while they were negatively correlated with the ELA amounts. Due to gestational diabetes, APLN-13, APLN-36, NO, glucose, and triglyceride increased, and ELA decreased. CONCLUSIONS It is predicted that the glucose increase in GDM is because Apelins reduce glucose transport to erythrocytes by inhibiting the sodium-dependent glucose transporter (SGLT) and that the increase in triglyceride and NO may be associated with high glucose levels in GDM. As a result, we believe that the above-mentioned chemicals may cause GDM Pathology by triggering one another.

Abstract
OBJECTIVE Obesity is a serious public health problem associated with excessive food intake. Regulation of food intake in highly organized organisms is under the control of a large number of orexigenic and anorexigenic molecules. Therefore, the main purpose of this study has been to determine the relationship between obesity and some of the circulating orexigenic and anorexigenic peptides that have a role in appetite control and to determine whether the concentrations of these molecules differ according to blood groups. PATIENTS AND METHODS The study included 400 individuals of whom 100 were obese women, 100 obese men, 100 healthy men and 100 healthy women. Obese women and men were divided into 4 groups, according to their blood groups. In the control group, healthy women and healthy men were similarly divided into 4 blood groups. Each blood group within the groups, therefore, had 25 participants. RESULTS When leptin, nesfatin-1, obestatin and neuropeptide-Y, ghrelin and galanin levels of the control group and obese participants were compared, regardless of blood groups, leptin, nesfatin-1, obestatin and neuropeptide-Y were significantly higher, whereas only the ghrelin levels were significantly lower in obese patients. When the amounts of these hormones were measured according to gender, the situation was similar. When leptin, nesfatin-1, obestatin and neuropeptide-Y values of the control and obese participants' blood groups were compared with each other; these hormones were high in all blood groups; however, leptin levels in A blood group, nesfatin-1 levels in AB and O blood group, obestatin levels in AB blood group, neuropeptide-Y levels in A, B, AB blood groups were significantly higher. When the ghrelin levels of the blood groups in the control group and obese participants were compared, it was only significantly lower in the AB blood group. The ghrelin levels in the other blood groups of the obese individuals were again low, but not significantly so. When the distribution of hormones according to gender was evaluated, a situation parallel to the above results was recorded. CONCLUSIONS Leptin, nesfatin-1, obestatin and neuropeptide-Y and galanin levels of obese individuals were significantly higher than the control values, whereas the ghrelin values were significantly lower regardless of blood groups. Also, these hormones in blood partly varied with ABO blood groups. These different concentrations of hormones in ABO blood groups might be related with stimulation or suppression of appetite in human. However, further studies in other ethnic groups are needed to confirm these results.

Abstract
This study was performed to evaluate whether the use of drugs in the treatment of osteoporosis in women is associated with COVID-19 outcomes. The results showed that the risk of hospitalization, intensive care unit admission, and mortality was not altered in individuals taking anti-osteoporosis drugs, suggesting no safety issues during a COVID-19 infection. INTRODUCTION Whether patients with COVID-19 receiving anti-osteoporosis drugs have lower risk of worse outcomes has not been reported yet. The aim of this study was to evaluate the association of anti-osteoporosis drug use with COVID-19 outcomes in women. METHODS Data obtained from a nationwide, multicenter, retrospective cohort of patients diagnosed with COVID-19 from March 11th to May 30th, 2020 was retrieved from the Turkish Ministry of Health Database. Women 50 years or older with confirmed COVID-19 who were receiving anti-osteoporosis drugs were compared with a 1:1 propensity score-matched COVID-19 positive women who were not receiving these drugs. The primary outcomes were hospitalization, ICU (intensive care unit) admission, and mortality. RESULTS A total of 1997 women on anti-osteoporosis drugs and 1997 control patients were analyzed. In the treatment group, 1787 (89.5%) women were receiving bisphosphonates, 197 (9.9%) denosumab, and 17 (0.9%) teriparatide for the last 12 months. Hospitalization and mortality rates were similar between the treatment and control groups. ICU admission rate was lower in the treatment group (23.0% vs 27.0%, p = 0.013). However, multivariate analysis showed that anti-osteoporosis drug use was not an independent associate of any outcome. Hospitalization, ICU admission, and mortality rates were similar among bisphosphonate, denosumab, or teriparatide users. CONCLUSION Results of this nationwide study showed that preexisting use of anti-osteoporosis drugs in women did not alter the COVID-19-related risk of hospitalization, ICU admission, and mortality. These results do not suggest discontinuation of these drugs during a COVID-19 infection.

Abstract
Abstract
Objective
COVID-19 is a disease with high mortality, and risk factors for worse clinical outcome have not been well-defined yet. The aim of this study is to delineate the prognostic importance of presence of concomitant cardiac injury on admission in patients with COVID-19.
Methods
For this multi-center retrospective study, data of consecutive patients who were treated for COVID-19 between March 20 - April 20 2020 were collected. Clinical characteristics, laboratory findings and outcomes data were obtained from electronic medical records. In-hospital clinical outcome was compared between patients with and without cardiac injury.
Results
A total of 607 hospitalized patients with COVID-19 were included in the study; the median age was 62.5±14.3 years, and 334 (55%) were male. Cardiac injury was detected in 150 (24.7%) of patients included in the study. Mortality rate was higher in patients with cardiac injury (42% vs. 8%; p<0.01). The frequency of patients who required intensive care unit (ICU) (72% vs.19%), who developed acute kidney injury (AKI) (14% vs. 1%) and acute respiratory distress syndrome (ARDS) (71% vs. 18%) were also higher in patients with cardiac injury. In multivariate analysis, age, coronary artery disease (CAD), elevated CRP levels, and presence of cardiac injury (OR: 10.58, 95% CI: 2.42–46.27; p<0.001) were found to be independent predictors of mortality. In subgroup analysis, including patients free of history of CAD, presence of cardiac injury on admission also predicted mortality (OR: 2.52, 95% CI: 1.17–5.45; p=0.018).
Conclusion
Cardiac injury on admission is associated with worse clinical outcome and higher mortality risk in COVID-19 patients including patients free of previous CAD diagnosis.

Abstract
Context Studies investigating the association between serum IGF-1, and thyroid nodule, ovarian or thyroid volume in polycystic ovarian syndrome (PCOS) are limited. Objective We aimed to analyze the association between serum IGF-1 level, and ovarian or thyroid volume, or thyroid nodule in PCOS. Design The study was performed between June 2017 and August 2019 as prospective design. Subjects and Methods Adult females with new-onset PCOS were included. The patients having comorbid illness, or using medication were excluded. Basic tests, thyroid and ovarian sonography were performed. The patients were grouped according to thyroid nodule(absent/present) and ovarian volume (<10mL/≥10mL). We planned to find a positive association between IGF-1, and thyroid nodule, thyroid or ovarian volume in PCOS. Results Of total 118 patients, 11(9%) had thyroid nodule. The patients with thyroid nodule had a higher ovarian volume (p=0.006). No correlation was found between GH or IGF-1, and thyroid or ovarian volume. IGF-1 was not a predictor for thyroid nodule or higher ovarian volume. Thyroid nodule was a significant predictor for higher ovarian volume. Conclusion Our study is the first to analyze the association between IGF-1 and thyroid nodule in PCOS. We found that thyroid nodule was associated with thyroid and ovarian volume, but IGF-1 was not associated with thyroid nodule, thyroid or ovarian volume.

Abstract
OBJECTIVE The primary objective of this study was to evaluate the frequency and impact of acute myocardial injury on prognosis in hospitalized COVID-19 patients. PATIENTS AND METHODS This was a retrospective study that included consecutive hospitalized patients with COVID-19. Clinic-demographic characteristics, laboratory values, and high-sensitivity troponin I were extracted from the electronic database. Mortality and other clinical complications, including respiratory failure requiring invasive mechanical ventilation and acute kidney injury were recorded. Myocardial injury was defined as having a serum troponin I value >19.8 ng/mL. We performed Kaplan-Meier survival analysis and Cox regression to determine survival times and independent predictors of mortality. RESULTS A total of 324 patients were included. Seventy-seven patients (23.8%) had acute myocardial injury. The primary outcome measure, namely death, occurred in 54.5% and 3.2% of the patients with and without myocardial injury, respectively. Notably, 75.3% of the patients with myocardial injury and 6.5% of the patients without myocardial injury developed ARDS. Overall, 50 out of 324 patients (15.4%) died during the study period. The mortality rate was 54.5% in patients with myocardial injury and 3.2% in patients without myocardial injury. Mean survival times were significantly different between the groups (15.1±0.9 days in patients with myocardial injury and 24.4±0.7 days in patients without myocardial injury, log-rank test p-value <0.001). CONCLUSIONS The presence of chronic kidney disease and application of invasive mechanical ventilation were found to be independent predictors of in-hospital mortality. The presence of acute myocardial injury was common but not independently associated with mortality among hospitalized COVID-19 patients.

Abstract
Renalase (RNLS) is synthesized mainly in renal tissues. The function of RNLS in cancerous renal tissues has not been investigated. We investigated the synthesis of RNLS in chromophobe renal cell carcinoma, papillary renal cell carcinoma and clear cell renal cell carcinoma with Fuhrman grades (FG): FG1, nucleoli are absent or inconspicuous and basophilic; FG2, nucleoli are conspicuous and eosinophilic and visible but not prominent; FG3, nucleoli are conspicuous and eosinophilic; FG4, extreme nuclear pleomorphism, multinucleate giant cells, and/or rhabdoid and/or sarcomatoid differentiation. We used 90 tissue samples including 15 healthy controls, 15 chromophobe renal cell carcinoma tissues and 10 papillary renal cell carcinoma renal tissues: 12 FG1, 14 FG 2, 14 FG 3 and 10 FG4. RNLS in the tissue samples was measured using enzyme linked immunosorbent assay and immunostaining of RNLS in these tissues. RNLS was significantly greater in the chromophobe renal cell carcinoma and papillary renal cell carcinoma tissues than the control. The least amount of RNLS was found in the renal tissues of clear cell renal cell carcinoma FG1; the amount of RNLS increased as the FG grades increased. Because RNLS increased significantly in renal tissues due to cancer, except for clear cell renal cell carcinoma FG1, RNLS may be useful biomarker for distinguishing grades of renal cancer. Because RNLS increases cell survival, anti-RNLS preparations may be useful for treating cancer in the future.

Abstract
Despite significant advances in medicine, mortality due to cardiovascular disease is not yet preventable. We investigated the amounts of elabela (ELA) and apelin, synthesized by cardiomyocytes, and changes of these compounds in cardiac tissue and circulation after administration of iloprost (ILO) and sildenafil (SIL) in rats with induced myocardial ischemia (MI). We also investigated a connection with circulating troponin-I, creatine kinase (CK), creatine kinase-myocardial band (CK-MB) and nitric oxide (NO), and total anti-oxidant (TAS)/total oxidant status (TOS). We established eight study groups of five rats each. Group 1, sham, was given only physiologic serum; group 2, ILO; group 3, SIL; group 4, ILO + SIL; group 5, MI; group 6, MI + ILO; group 7, MI + SIL; group 8, MI + ILO + SIL. Troponin-I, CK, CK-MB and TAS-TOS were investigated using an autoanalyzer. NO, ELA and apelin were analyzed by ELISA. Tissue apelin and ELA expressions and localizations were determined by immunohistochemistry. The MI group compared to the control (sham) group showed that ELA, apelin, troponin-I, CK, CK-MB, NO and TOS levels were elevated significantly. Concentrations of these factors increased in MI, but decreased after ILO and SIL administration. The largest decrease of TOS was identified in the ILO + SIL group. ELA and apelin may be novel indicators of MI and administration of ILO and SIL, individually or together, may be useful for treating MI.

An eight-case 1q21 region series: novel aberrations and clinical variability with new features. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2019; 63:548-557. [PMID: 30773728 DOI: 10.1111/jir.12592] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/13/2018] [Revised: 11/04/2018] [Accepted: 12/31/2018] [Indexed: 06/09/2023]
Abstract
BACKGROUND Rearrangement of the 1q21 region of chromosome 1 manifests as multiple phenotypes, including microcephaly, intellectual disability, dysmorphic facial features, eye abnormalities, cardiac defects, genitourinary anomalies, autism spectrum disorder, psychiatric conditions and seizures. Herein, we describe eight patients with 1q21 deletion and duplication syndromes, and novel deletions and findings. METHODS Chromosomal microarray analysis was performed to identify the existence of copy number variation. Quantitative polymerase chain reaction was applied using specific primers for the control and 1q21 region of chromosome 1. Mutational analysis was performed in case 5 using direct genomic sequencing for exons 1-6 in RBM8A. RESULTS Copy number variation analysis identified seven deletions and one duplication of the 1q21 region in the eight patients. In addition, four variations were de novo, and two deletions are reported here for the first time. One of the cases (case 7) presents moderate intellectual disability and dysmorphic facial findings, whereas chromosomal microarray analysis showed that case 7 had an 889-kb deletion in the 1q21 proximal region (GPR89A, PDZK1, CD160, POLR3C and NBPF12). CONCLUSION Although the deletion in case 5 did not include the thrombocytopenia-absent radius syndrome critical region or the RBM8A gene, he had pectoral muscle hypoplasia, radius and humerus hypoplasia and short curved ribs, which are indicative of a potential thrombocytopenia-absent radius region modifier. The findings in case 7 suggest that the proximal part of the 1q21 microdeletion syndrome region might be very important for the onset of clinical manifestations. Some novel findings were observed in the presented cases, such as radius and humerus hypoplasia and brain stem hypoplasia. The presented findings expand the spectrum of 1q21 aberrations and provide evidence of genotype-phenotype correlations for this region.

Abstract
We investigated the expression of irisin in renal cancers using immunocytochemistry. Irisin has been reported to exhibit anticancer properties. The study groups consisted of 22 cases each of control renal tissue, oncocytoma, chromophobe renal cell carcinoma (RCC), clear cell RCC (Fuhrman nuclear grades 1, 2, 3 and 4) and papillary RCC. We evaluated 10 slides for each of 176 cases. Slides were immunostained for irisin and histoscores were calculated for the prevalence and strength of immunostaining. Fuhrman nuclear grade 1, 2, 3 clear cell RCC and papillary RCC exhibited no irisin immunoreactivity. Irisin immunoreactivity was observed in some Fuhrman nuclear grade 4 RCCs. We found a significant decrease in irisin staining in chromophobe RCC compared to the control. Immunoreactivity in the oncocytoma tissue was comparable to the control group. Irisin immunoreactivity in chromophobe RCC decreased and no immunoreactivity was observed in Fuhrman nuclear grade 1, 2, 3 clear cell RCC and papillary RCC. Immunistochemical screening of irisin in renal oncocytomas and renal cancers may be useful for differential diagnosis.

Abstract
OBJECTIVES AND BACKGROUND Familial Mediterranean Fever (FMF) is characterized by recurrent fever episodes as a result of inflammation of serous membranes. Changes in the number of different mtDNA copy number variations, detected in FMF patients, who developed amyloidosis, might be an important parameter in the understanding of the pathophysiology of the disease. METHODS Changes in the mtDNA copy number between 50 patients with FMF, who had M694V homozygote mutation and amyloidosis, and 50 healthy controls, who had not any MEFV mutation or FMF clinical finding, were examined. The 22 MEFV mutations were analyzed by Pyromark Q24 system. Quantitative analysis was performed on RT-PCR. The level of mtDNA was calculated using the delta Ct (ΔCt) of average Ct of mtDNA and nDNA (ΔCt = Ct mtDNA-Ct nDNA) in the same well as an exponent of 2 (2ΔCt). RESULTS A significant decrease in the amount of mtDNA was detected in FMF patients with M694V homozygous mutation carriers, who developed amyloidosis compared to the control group (p < 0.001). CONCLUSION In this study, mitochondrial dysfunction, which has been identified through changes in the mitochondrial genome in many diseases, was identified by showing that the copy number variations of mtDNA in leukocytes also decreased for FMF disease (Tab. 3, Fig. 1, Ref. 21).

Abstract
OBJECTIVE Osteoprotegerin (OPG) is considered an important biomarker in cardiovascular (CV) disease. CV disease is the most common cause of mortality in patients with rheumatoid arthritis (RA), a consequence of accelerated atherosclerosis. The present study aimed to evaluate the relationship of serum OPG levels to arterial stiffness, carotid intima-media thickness (CIMT), and clinical and laboratory indices in RA patients. PATIENTS AND METHODS Included in the study were 68 RA patients with no history or signs of CV disease and 48 healthy subjects Disease activity was assessed by the 28-joint disease activity score (DAS28) in RA patients. Serum OPG level was measured using enzyme-linked immunosorbent assay (ELISA). Carotid femoral pulse wave velocity (PWV) was measured as an index of arterial stiffness and CIMT was evaluated by carotid ultrasonography. RESULTS The mean serum OPG level was significantly higher in RA patients than controls (p < 0.001). Mean PWV and CIMT were also significantly increased in RA patients compared to controls (both p < 0.001). In RA patients, serum OPG level was significantly correlated with PWV and CIMT, as well as rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibody; but not with DAS28, high-sensitivity C-reactive protein (hsCRP), or erythrocyte sedimentation rate. CONCLUSION Serum OPG levels were increased and correlated with CIMT and PWV in RA patients. In addition to PWV and CIMT, OPG may be a useful biomarker for CV risk management in RA patients.

Abstract
Partial trisomy of chromosome 5 was first described by Lejeune et al. in 1964 on the short arm (12). The vast majority of the partial trisomy 5 cases include 5p duplications; however we reported a small supernumerary marker chromosome. General symptoms include developmental delay, mental retardation, seizures, respiratory difficulties, congenital heart defects, abdominal muscle hypoplasia and dysmorphic features such as macrocephaly, enlarged anterior fontanelle, dolichocephaly, upslanting palpebral fissures, epicanthal folds, hypertelorism, abnormal ears, midface hypoplasia, short nose, broad nasal bridge and microretrognathia. Arachnodactyly and club foot may be seen as cytoskeletal abnormalities and, hypotonia may be determined in neurological exam. Here we reported a case with developmental delay, attention deficit hyperactivity disorder, mild mental retardation and dysmorphic features, caused by a new small supernumerary marker chromosome, generating partial trisomy 5pI 2-q 11.2. To our knowledge, this small supernumerary marker chromosome has not been reported before. Severe type of partial trisomy 5 includes seizures, congenital heart defects, hypotonia and failure to thrive. Previously reported partial trisomy 5 cases, who showed severe phenotype, had usually duplicated 5p13 region. Therefore, patients, who do not have duplicated 5p13, showed mild phenotype. Also, duplication of the long arm of chromosome 5, may contribute to the milder phenotype and the longer survival in partial trisomy 5 patients. Attention deficit hyperactivity disorder, which we described in the present case, may be a result of partial trisomy 5, because it includes ADHD4 gene. This case may help better understanding the karyotype/phenotype correlation related to partial trisomy 5.

Abstract
OBJECTIVE The objective of this study is to evaluate the demographic characteristics, blood pressure and blood glucose and the other related factors that affect the microalbuminuria levels in the obese patients aged 40 and above who applied to the primary care for medical evaluation. MATERIALS AND METHODS The population of the research, which was a cross-sectional type, comprised obese patients aged 40 and above who had applied to the community health centers in the center of Malatya. A total of 422 obese patients consisting of 116 males and 306 females were included in the research. The anthropometric measurements of the participants were determined, their blood pressures and their random blood glucoses were evaluated, as well. A microalbuminuria measurement was performed in the urine samples taken from the patients using "Nycocard Reader II" device. FINDINGS The incidence of microalbuminuria in patients was found as 31.5%, whereas the incidence of macroalbuminuria was 6.6%. The incidence of microalbuminuria in female patients was 32.7%, while it was 28.4% in male patients; on the other hand, the incidence of macroalbuminuria in female patients was found as 6.8%, whereas this percentage was determined as 7.8 in male patients (p > 0.05). The probability of the incidence of microalbuminuria increased 2.8 times more in those with the diastolic blood pressure of 90 mmHg and above when compared to those without it (GA: 1.79-4.56), whereas the incidence increased 3.2 times more in those with the random blood glucose of 200 mg/l and above (GA: 1.32-7.84) (p < 0.001). In our study, among the variables predicting the microalbuminuria in obese patients; the cutoff values of the diastolic and systolic blood pressures, the waist circumference were found as >85 mmHg; >130 mmHg; >141 mg/dl, respectively, in male patients and found as >85 mmHg, >114 cm, and 109 cm, respectively, in female patients. The sensitivity and specificity of the tests indicating the cutoff values showed significance (p < 0.05). There was no statistically significant relevance between the microalbumin levels of the obese patients via the anthropometric criteria, except for their waist circumference (p > 0.05). RESULT In this study, the blood pressure and blood glucose levels of the patients along with their waist circumference that indicated a central obesity were specified as the determinants of microalbuminuria. While the obese patients are being evaluated in terms of proteinuria, the cutoff values of these variables can be taken into consideration.

Abstract
Warburg Micro Syndrome (WARBM, MIM 600118) is a rare, severe autosomal recessive neurodevelopmental disorder characterized by microcephaly, microphthalmia, microcornea, congenital cataract, cortical dysplasia, corpus callosum hypoplasia, intellectual disability, hypotonia and hypogonadism. RABS, small G proteins belonging to the RAS superfamily, are master regulators of vesicle trafficking in the cell. The identification of mutations in the RAB3GAP1 and RAB3GAP2 genes, which together encode the RAB3GTPase-activating protein, a key regulator in calcium-mediated exocytosis of neurotransmitters and hormones, has underpinned abnormal development of the brain, eye and genitalia as cardinal features of this syndrome. More than 100 patients have been reported with WARBM, with mutations in the RABGAP1, RABGAP2, RAB18 and TBC1D20 genes. The objective of the study was to describe the recurrent RAB3GAP1 mutations and compare the clinical features of the patients with WARBM in the Turkish population. Here we report two brothers with Warburg Micro Syndrome 1 from a non-consanguineous Turkish family with clinical features similar to those previously reported in Turkish patients with RAB3GAP1 mutations. We found that the c.748+1G>A splice-site mutation in RAB3GAP1 intron 8 is common and has so far only been detected in patients of Turkish ethnic origin. Although one of our patients has a distal extra crease on the 4th finger and another has nephrolithiasis, there does not appear to be any specific phenotypic findings associated with this mutation.

Abstract
OBJECTIVE The effect of vitamin D and renin-angiotensin-aldosterone system blockade medications in pathophysiology of contrast induced nephropathy (CIN) is controversial. The effects of paricalcitol (active vitamin D analogue) and losartan treatments in an experimental model of CIN were investigated in this study. MATERIALS AND METHODS Thirty-six male Wistar albino rats were examined in five treatment groups. Placebo group (Group A; n = 4) received no active medication; control group (Group B; n = 8) received only contrast media (CM); Group C (n = 8) received paricalcitol; Group D (n = 8) received losartan and Group E (n = 8) received paricalcitol plus losartan. CIN was induced by NG-nitro-L-arginine methyl ester and indomethacin before iohexol injection. Renal histopathological findings were categorized and renal immunohistochemical examinations by caspase-3 rabbit primary antibody were performed. RESULTS Creatinine and cystatin C levels significantly increased in the treatment groups, compared to Group A. However, creatinine levels were not significantly increased in Groups C, D and E compared to Group B. Compared to Group B, a significant increase of cystatin C levels was observed in Group D (p < 0.01). In Group E, when paricalcitol treatment was added to losartan treatment, cystatin C levels were similar to Group B (p = 1.00). In histopathological and immunohistochemical examination frequency of Grade 2/3 tubular necrosis and renal caspase 3 activity scores were significantly higher in the losartan treatment group compared to the other treatment groups. The histopathological effects related to losartan treatment were found to be reversed when paricalcitol treatment was combined. CONCLUSIONS Our findings suggest that paricalcitol treatment counteracts increased contrast induced nephropathy caused by losartan. These findings warrant further clinical studies to investigate the benefit of paricalcitol in CIN prophylaxis.

Abstract
OBJECTIVE The SYNTAX Score was recently developed to characterize the coronary vasculature with respect to the number of lesion's location, complexity, and functional impact and it is a quantitative scoring system to assist with patient selection for optimal revascularization strategy between percutaneous coronary intervention (PCI) and coronary artery by-pass surgery (CABG). b2-glycoprotein I (b2GPI), a plasma protein that binds cardiolipin, acts as a modulator of platelet aggregation and coagulation. Antibodies to b2GPI may have a role in atherosclerosis by inducing endothelial cell activation. We investigated the relationship between anti beta 2 GPI and severity of coronary artery stenosis by calculating the SYNTAX Score among patients undergoing CABG surgery. PATIENTS AND METHODS We prospectively investigate 612 patients who undergo elective coronary angiography between September 2012 and June 2013. Patients were evaluated for blood chemistry and anti-b2GPI IgA, IgM and IgG. Ninety seven patients with complete biochemical analysis including anti Beta 2 GPI antibodies and undergone CABG have been enrolled in this study. We divided patients in to 2 groups according to the SYNTAX scores. Group 1 included 48 patients with low SYNTAX scores (<23) and group 2 included 49 patients with intermediate and high SYNTAX scores (>23). RESULTS There was significant correlation between elevated anti b2GPI IgG levels and higher SYNTAX score which indicate advanced and complex CAD. In this study, lesion complexity increased progressively with increasing anti-b2GPI-IgG type of antibody levels. According to this findings, anti-b2GPI-IgG is a strong predictor of higher SYNTAX score. CONCLUSIONS In addition to the traditional risk factors for atherosclerosis, the proinflammatory and procoagulant activities of antiphospholipid antibodies appear to be important risk factors for atherosclerotic occlusive disease.

Abstract
The aim of this study was to assess in vitro the improvement in release kinetics for teicoplanin and the inhibition of bacterial adhesion on calcium sulfate-soaked PMMA discs. Calcium sulfate has been used in vivo and shown to be biocompatible, and prevention of bacterial adhesion may be expected with calcium sulfate-soaked polymethylmethacrylate (PMMA). Discs were made by adding teicoplanin and calcium sulfate in powder form to PMMA powder. The antibiotic concentration eluted from PMMA discs was assayed by agar diffusion assay. Nonadherent bacteria were removed by washing and adherent bacteria were detached by sonication. The suspension including nonadherent bacteria was seeded on sheep blood agar plate and incubated for 24 h at 37 degrees C for the growth of microorganisms. The teicoplanin released from discs containing calcium sulfate was higher than that released from discs which had not been soaked with calcium sulfate. The count of bacteria adhering to the calcium sulfate-soaked discs was lower than that from the discs without calcium sulfate. In conclusion, the addition of calcium sulfate to teicoplanin-loaded PMMA bone cement may provide local antibiotic concentrations higher than MIC values due to increased antibiotic release. Furthermore, calcium sulfate was found to be effective in reducing bacterial adherence to treated discs.

Abstract
Salusins expressed in a variety of tissues exert a hypotensive effect owing to their vasodilator action. They are found in serum and tissues in two different forms: salusin-α and salusin-β. Metabolic syndrome (MetS) is an important public health problem characterized by diabetes, obesity, abnormal blood lipid levels and high blood pressure. We investigated how salusins in the circulation and in kidney tissues change in relation to MetS. Experiments were conducted on 5-week-old Sprague-Dawley male rats assigned to either a control group or a MetS group. Controls were fed standard rat food and water ad libitum, while the MetS group was fed standard food with 10% fructose solution added to their drinking water for three months. After three months, all animals were sacrificed after a one night fast. Blood and tissues were collected and stored appropriately. Biochemical parameters were analyzed using the Konelab 60 auto-analyzer. Salusin-α and salusin-β levels in the blood and kidneys were studied using the ELISA method. The salusin expression in the renal tissue was shown by immunohistochemical staining. Compared to the control group, the MetS group showed elevated uric acid and other lipid parameters for high-density lipoprotein cholesterol. Serum salusin-α and salusin-β levels were decreased; however, salusin levels/mg kidney tissue were elevated. Immunohistochemical analysis of salusins in kidney tissue revealed their presence in the epithelium cells of the glomeruli, and proximal and distal tubule cells. The expression of both peptides in renal tissues was greater in the MetS group than in the control group. We believe that salusins are critical mediators in the etiopathology of MetS. Altered salusin levels are thought to regulate hypertension, which is a component of MetS.

Abstract
OBJECTIVES Kidney transplantation is the best treatment method associated with improved quality of life and better survival for patients with end-stage renal disease. We started performing kidney transplantations in November 2010. We have performed 19 kidney transplantations so far. Fourteen of these were from living donors and five from deceased donors. Here, we present our initial experiences with 14 kidney transplant recipients from living donor kidney transplantations. MATERIALS AND METHODS All recipients and their donors underwent detailed clinical history and examination. Recipients and their donors were followed in the transplant clinic during hospitalization. RESULTS The male-to-female ratio was 11:3 in recipients. The mean age of recipients was 27.8 years (range 4-58 years). The number of the related, emotionally related, and unrelated transplantations were 9, 3, 2, respectively. The mean warm ischemic time was 95.7 seconds (range 52-168 seconds). Urine output started immediately after vascular anastomosis in all. The mean time of discharge from hospital was postoperative day 8 (range 4-18 days). The mean flow up was 125 days (range 18-210 days). Graft survival was 100% in this period, but one patient died from sepsis after 56 days. No kidney was lost from rejection, technical causes, infection, or recurrent disease. CONCLUSION If transplant centers are as equipped and experienced as ours, kidney transplant programs should be started immediately so that they can reduce the number of the patients in waiting list for kidney transplantation.

Abstract
The term "fourth-degree burn" is not very often found in the literature because it is often associated with lethal injury. These injuries are characterized by exposure of viable tissue such as tendon or bone and are associated with challenging wound closure. The goal of reconstruction is to provide adequate soft tissue coverage and restoration of function. Several treatment modalities have been used to serve this purpose. We present four male patients with fourth-degree burns of the extremities, treated with negative pressure wound therapy. The patients' age ranged from 15 to 49 yr (mean, 28 yr). The total body surface area burned ranged from 3 to 60% (mean, 34.25%). Negative pressure wound therapy was applied for 16-30 days (mean, 23.75 days). Three split-thickness skin grafts and one bipedicled local flap were performed. Wound closure was completed in 28 to 50 days. The results were satisfactory for both physicians and patients. Our longest follow-up was three years. The results achieved in this group of patients revealed the negative pressure wound therapy was a reliable alternative method in the treatment of fourthdegree burns.

Abstract
The aim of the study was to investigate adrenomedullin (ADM) levels and its relation with insulin resistance in women with polycystic ovary syndrome (PCOS). Twenty-nine women with PCOS and 29 age- and body mass index (BMI)- matched control subjects were included in the study. PCOS was defined according to criteria by the Rotterdam European Society of Human Reproduction and Embryology/American Society for Reproductive Medicine (ESHRE/ASRM)-sponsored PCOS consensus workshop group. A full clinical and biochemical examination including basal hormones and metabolic profile was performed. Insulin resistance was calculated by using the homeostasis model assessment of insulin resistance index (HOMA-IR). Plasma ADM levels were measured by high performance liquid chromatographic (HPLC) method. Plasma ADM, fasting insulin levels and HOMA-IR were significantly higher in patients with PCOS than the control group. ADM levels were positively correlated with insulin levels and HOMA-IR index. The best cut-off value of ADM levels to identify the presence of insulin resistance (HOMA-IR≥2.7) was 30.44 ng/ml. Calculated odds ratio of insulin resistance by using logistic regression analysis, as predicted by ADM, was 0.15 (95% confidence interval, 0.037-0.628; p=0.009). In multiple regression analysis, ADM level was an independent predictor of HOMA-IR index. Our finding indicated that ADM levels increased in women with PCOS in accordance with HOMA-IR. ADM could be a significant independent determinant of insulin resistance in women with PCOS.

Abstract
BACKGROUND In recent years, the use of herbal weight-loss products sold over the Internet has rapidly increased; however, the safety of these products has not been well documented yet. More importantly, the declared ingredients in these products could be different than the marketed contents. METHODS Nine different herbal weight-loss products sold over the Internet were obtained. The ingredients of each product were analyzed in the Laboratory of Forensic Medicine and the Scientific and Technological Research Laboratory of Inonu University. RESULTS Although all studied weight-loss products were presented as pure herbal, three of them contain sibutramine, three contain caffeine, and three contain caffeine + temazepam. The amount of sibutramine in each capsule was found to be over 10 mg. We analyzed toxic and trace element levels of nine herbal products and found that these herbal products, even in low amounts, contain Pb, Al, Ni, and Ba. CONCLUSIONS Our results indicate that herbal weight-loss products available without prescription and claimed to be purely herbal may contain pharmaceutical substances like sibutramine or temazepam in high doses. Moreover, they also may become contaminated with toxic metals. Since people commonly use these products unaware of its real constituents and without the suggestion or control of a physician, they might cause various health problems some of which might be harmful. Strict legal rules and control mechanisms must be established to minimize their possible harmful effects.

Abstract
Temozolomide (TMZ) is an alkylating, antineoplastic agent which is being used to treat cases of refractory anaplastic astrocytoma, newly-diagnosed glioblastoma multiforme and metastatic melanoma. TMZ causes lymphopenia and T-cell dysfunction in most of the patients. Related to this toxicity several opportunistic infections have been reported in the literature, but were not well characterized. To further investigate this topic, relevant English language studies were identified through Medline. There were 36 previously reported cases of infection related to TMZ. The median age of the cases was 55 years (range 33-73). The most frequently experienced infections were mucocutaneous candidiasis (n=11; 28.2%), herpes zoster (n=5; 12.8%), herpes simplex virus (n=4; 10.2%), cytomegalovirus (CMV) (n=5; 12.8%), pneumocystis carinii pneumonia (PCP) (n=3; 7.6%), hepatitis B virus (HBV) (n=2; 5.1%) and others (n=9; 23%). Mortality rates were 28.5% (n=4/14) in patients with reported outcome. In this survey, about one third of the TMZ-related severe infections resulted in death. Patients treated with TMZ are at increased risk for opportunistic viral and bacterial infection. Therefore, close monitoring of patients receiving TMZ for opportunistic infections should be carried out.

Abstract
Even if calculating the exact cost of burn treatment is a very hard task, the study of cost analysis provides financial perspective. We performed a cost analysis study in our burn centre to respond to questions about total patient treatment cost and the length of hospital stay. We reviewed all patients admitted to the Gulhane Military Medical Academy Burn Centre in Ankara, Turkey, between March 2005 and August 2008. Forty-three patients with major burns were identified on the basis of the study criteria. The data regarding total treatment cost and the length of hospital stay for each type of burn (flame, scald, electric) were collected at the end of the study. The average total body surface area burned was 36 ± 7%.. The average duration of hospital stay was 73 ± 33 days. Patients with electrical burns stayed longer in hospital than patients with other types of burn injuries. Each one per cent of burn corresponded to a mean hospital stay of two days. The overall mean total cost was $US 15,250. The mean total cost of electrical burns was the highest, with $US 22,501 ± 24,039. Even if the costs associated with burn injury are higher than some other well-known health-related problems, they have not been much studied. Reports have produced different results, but it should be kept in mind that although the results of cost analysis studies may vary they must be performed in all newly established burn centres in order to form a financial overview.

Abstract
This study was carried out to investigate the potential vectors and relative mosquito infection rates of Dirofilaria immitis throughout two mosquito seasons (2008-2009) in Kayseri province where is located in Central Anatolian part of Turkey. For this aim, totally 1198 genomic DNA pools, extracted and grouped according to the species and collection site (1-17 specimens/pool) from 6153 mosquito specimens, were examined by PCR using species-specific primers for D. immitis. The captured mosquitoes from 46 focuses were survived under in vitro conditions for 7 days to allow the development of larval stages of D. immitis. DNA extraction was performed individually to both thorax-head and abdomens in order to determine infective and infected mosquito specimens, respectively. The most abundant mosquito species in the study area was determined as Ae. vexans (51.7%) and this was followed by Cx. pipiens (42.1%), Cx. theileri (3.1%), Cs. annulata (1.5%), An. maculipennis (1.0%) and Cx. hortensis (0.6%). The PCR results indicated that 9/312 and 12/312 pools from Ae. vexans abdomens and thorax-heads were positive for filarial DNAs, respectively where as 3/241 pools of each abdomens and thorax-heads from Cx. pipiens were positive for D. immitis DNAs. The minimum infection rates (MIRs) for Ae. vexans and Cx. pipiens were calculated as 0.41 and 0.12, respectively. Although D. immitis DNA's were found in both pools from Ae. vexans and Cx. pipiens, the calculated MIRs provide evidence that Ae. vexans could be the main potential vector of D. immitis in Kayseri.

Abstract
Obesity, characterized by hyperleptinemia and hypoghrelinemia, has become a major health problem all over the world and is associated with an increased risk of complications including insulin resistance, hypertension, dyslipidemia, diabetes mellitus and atherosclerosis. The use of the pancreatic lipase inhibitor Orlistat can help seriously overweight people to achieve and maintain weight loss. The aim of our study was to compare the serum leptin and ghrelin levels in obese subjects who take orlistat with those receiving only dietary treatment. Twenty-one obese patients and 10 control subjects participated. The obese patients were divided into two groups; one group (n=11) took orlistat (120 mg, 3 times daily) and received dietary treatment and the other (n=10) only received the dietary treatment. The study lasted twelve weeks. The concentrations of serum ghrelin, leptin, insulin and C-peptide, and routine biochemical parameters, were measured in both groups. The serum ghrelin level was higher in control (183+/-62 fmol/ml) than obese (59+/-30 fmol/ml) subjects while the plasma leptin level was lower in control (8.7+/-12 microg/L) than obese (36.7+/-19 microg/L) subjects (all p<0.001). BMI and the total blood cholesterol, LDL and triglyceride levels fell significantly after both orlistat and dietary treatment in the obese subjects (all p<0.01), and the plasma ghrelin level rose (p<0.01). The leptin level demonstrated the opposite trend in both groups but only the patients taking orlistat showed a significant change (p<0.05).Taken together, these results show that orlistat has no effect on body weight in obese subjects additional to that conferred by a non-pharmacological life-style intervention. We therefore conclude that weight lost rather than type of treatment might be more valuable in obesity.

Abstract
OBJECTIVES To investigate the rates of cesarean deliveries in two different hospitals, which serve different populations in Turkey. METHODS The study was conducted at two centers, one of which is a university hospital in a rural area and the other a community hospital in capital city, for 5 years (1999-2003). The subjects were < 18 years old adolescent mothers. The adult controls ( 18 years) were further divided in two age groups: 18-35 years and > 35 years. RESULTS A total of 40,391 pregnant women were evaluated in both hospitals. Cesarean delivery rates in adolescent pregnancies were not higher than adults. Moreover, in community hospital, cesarean delivery rate in adolescents was significantly lower (17.12% vs. 28.84%). CONCLUSIONS We concluded that, the cesarean deliveries are not increased, and even decreased in adolescent pregnancies and biological immaturity is not a significant problem in adolescent pregnancy.

Abstract
Burn scars in early childhood often impairs normal development of the structures of the face. Multiple reconstructive interventions contribute to airway deformity with excessive scar and contracture band formation. Such patients are the most difficult group because of the risk of difficult ventilation and intubation in anesthesiology practice. Although developments in complex airway management techniques are increased, solutions may be achieved with simple approaches. For this purpose, we report about a patient with an anticipated difficult airway who has rejected awake fiberoptic intubation. The patient was managed successfully using classical laryngeal mask airway and nasogastric tube with the guidance of fiberoptic bronchoscope under deep sedation.
