Abstract
OBJECTIVES To evaluate whether PSA fluctuation can be used to predict the risk of prostate cancer. MATERIALS AND METHODS The study included 1244 patients who underwent prostate biopsy at Kartal Dr. Lutfi Kirdar City Hospital between 2013 and 2021 (848 in non-cancer; 396 in cancer). The patient's age, last two PSA values (PSA1 and PSA2) within three months before the biopsy, the duration between two PSAs (days), prostate size (g) and PSA density (PSAD) were all recorded. PSA fluctuation rate (PSAfr) was defined as the change rate between two PSA values. RESULTS PSAfr was significantly higher in the non-cancer group than in the prostate cancer group (15.2% (20.5) and 9.6% (14.4), P=.019). A Simple linear regression was used to examine the relationship between PSAfr and other factors such as age, PSA, PSAD, and prostate volume, but it was shown that these had no effect on PSA fluctuations. ROC analysis revealed a relatively low Area Under the Curve (AUC) for PSAfr (AUC, 0.584 (0.515-0.653)). However, the cut-off value of 12.35% was found to be significant, with a sensitivity of 58% and a specificity of 59% (P:.019, 95%CI). The odds ratio, adjusted for age, PSAD, and PSA2, was calculated as 0.545 (0.33-0.89) using logistic regression analysis to show the relationship between prostate cancer and PSAfr. As a result, those with high PSAfr were found to be 1.83 times less likely to be diagnosed with prostate cancer than those with low fluctuations. CONCLUSION PSAfr could be used in nomograms to predict prostate cancer risk and reduce the number of unnecessary biopsies.

Abstract
Abstract
Background
Atherosclerosis manifests itself differently in women compared to men. Since the pathophysiology of atherosclerotic plaques is known to be related to endothelial shear stress (ESS), it was hypothesized that female compared to male coronary arteries demonstrate a different i) ESS and ii) ESS related plaque progression.
Methods
1183 coronary arteries (male/female:944/239) from the PREDICTION trial were studied for differences in vessel geometry (plaque area (PA) and lumen area (LA)), hemodynamic parameters (flow, minimal ESS over 90 degree arc (minESS) and maximal ESS over 90 degree arc (maxESS)) and ESS related plaque progression (1 year follow up) measured as change in maximal plaque thickness and plaque burden comparing female to male arteries. Arterial geometry and ESS measures were derived from IVUS-based vascular profiling and reported per 3 mm segments. For plaque progression studies minESS was subdivided into low, mid and high (<1,1–1.7,>1.7 Pa). To test statistical differences univariate anova or linear mixed models were used.
Results
13030 3mm-segments (m/f: 10.465/2565) were analyzed. Female compared to male coronary arteries were smaller and presented with less plaque area (Table I). No differences in average ESS, minESS and maxESS were found for male versus female coronary arteries, partly explained by the lower flows in female arteries (Table I). The ESS-related plaque growth showed for both sexes an significant inverse relationship between maximal wall thickness (Figure, left) and plaque burden (Figure, right) and the three minESS categories. However, ESS-related plaque growth was not different for male vs females.
Conclusion
Our data demonstrated that vessel and plaque size are smaller in female compared to male coronary arteries. However, ESS and ESS related plaque progression were not different.

Abstract
Abstract
Background
The natural history of plaque growth is, among other systemic risk factors, related to the blood flow induced local shear stress. Especially at regions of low shear stress plaques are initiated. Upon plaque encroachment into the lumen, plaques will be exposed to high shear stress. Interestingly, it has been observed that individual plaques are very heterogeneous regarding the local shear stress exposure and remodeling patterns along the plaque length. However no information is available on the spatial heterogeneity of temporal changes in plaques burden. We studied the longitudinal spatial heterogeneity of plaque burden progression, regression, quiescence in human coronary plaques.
Methods
591 coronary arteries from 302 patients with coronary artery disease who presented with an acute coronary syndrome from the PREDICTION study were investigated for local plaque progression, regression, quiescence patterns after 6–10 months follow up. Arterial geometry was derived from angiography/IVUS-based vascular profiling and reported in 3 mm segments. Plaques were defined as >3 consecutive segments with maximal wall thickness>0.5 mm. Plaque progression was defined as >5% increase, regression as <−5% decrease, and quiescence as no change in plaque burden (plaque area/ total vessel area * 100%). Logistic mixed model regression analysis was performed with plaque progression features as outcome and plaque length as independent variable with vessel as random factor to account for clustering of the data.
Results
5658 3mm-segments of 661 plaques were analyzed. Plaque burden changes over time ranged from −22% to +20%, with an average of −0.4%±4% which was not significant different from 0. Among all plaques, 56% showed segments with plaque progression of more than 5%, 60% with plaque regression (<−5%) and 96% of the plaques had segments that did not change over time (quiescence). On average, 17% of the plaque length displayed plaque progression, 20% regression and 63% was quiescent. The presence and number of features (progression, regression, quiescence) within the plaque were significantly related to the plaque length (figure).
Conclusion
Plaques are very heterogeneous in plaque progression patterns. Most of the plaques show within the plaque length simultaneously more than one plaque progression feature (segments that do not change in plaque burden, segments that regress or progress). The number of observed plaque progression features was related to the plaque length.

Abstract
In this study, it was aimed to determine of diagnostic importance blood lipid levels in neonatal calves with sepsis. The study was carried out on a total of 70 calves, 60 with sepsis and 10 healthy calves. The calves with sepsis were included in the study, according to clinical and hematological findings. After routine clinical examinations of all the calves, blood samples were taken from the V. jugularis for hematological, lipid profile and biochemical analyzes. There were significantly (P < 0.05) decreased in body temperature, increased in respiration rate and capillary refill time in the calves with sepsis, compared to control group calves. The levels of blood urea nitrogen, creatinine concentrations of calves with sepsis were significantly higher (P < 0.05), however, levels of total cholesterol, HDL, LDL and albumin concentrations were significantly lower (P < 0.05) than control group. In addition, blood triglyceride and VLDL concentrations of calves with sepsis were higher than control group, however there was no statistical difference.In conclusion, serum total cholesterol, HDL and LDL in neonatal calves with sepsis could be used in evaluation of the sepsis.

Abstract
BACKGROUND Objective interpretation of laboratory test results used to diagnose and monitor diabetes mellitus in part requires the application of biological variation data (BVD). The quality of published BVD has been questioned. The aim of this study was to quality assess publications reporting BVD for diabetes-related analytes using the Biological Variation Data Critical Appraisal Checklist (BIVAC); to assess whether published BVD are fit for purpose and whether the study design and population attributes influence BVD estimates and to undertake a meta-analysis of the BVD from BIVAC-assessed publications. METHODS Publications reporting data for glucose, HbA1c, adiponectin, C-peptide, fructosamine, insulin like growth factor 1 (IGF-1), insulin like growth factor binding protein 3 (IGFBP-3), insulin, lactate and pyruvate were identified using a systematic literature search. These publications were assessed using the BIVAC, receiving grades A, B, C or D, where A is of highest quality. A meta-analysis of the BVD from the assessed studies utilised weightings based upon BIVAC grades and the width of the data confidence intervals to generate global BVD estimates. RESULTS BIVAC assessment of 47 publications delivered 1 A, 3 B, 39C and 4 D gradings. Publications relating to adiponectin, C-peptide, IGF-1, IGFBP-3, lactate and pyruvate were all assessed as grade C. Meta-analysis enabled global BV estimates for all analytes except pyruvate, lactate and fructosamine. CONCLUSIONS This study delivers updated and evidence-based BV estimates for diabetes-related analytes. There remains a need for delivery of new high-quality BV studies for several clinically important analytes.

Abstract
This paper gives an update on the local distributions of HCV genotypes in Aydin province of Turkey, provides a comparison with the previous records, and discusses the potential causal reasons shaping the evolving genotype profiles. Patient files from 2011 to 2016 were retrospectively analyzed, and newly detected cases were documented. Out of 286 patients, male and female ratios were determined to remain nearly the same (~50%). Genotype 1 was still the most common (90.2%), followed by genotype 3 (5.9%), genotype 2 (2.1%), and genotype 4 (1.4%) in frequency. There were international patients (4.50%). One patient had genotyped 2+3 together. Genotypes 4 and 2+3 were detected for the first time, and the patients with genotype 4 were interestingly all male and also domestic individuals. However, these patients traveled or lived abroad in the past due to occupational reasons, thereby likely acquired the infection while abroad. HCV surveillance system is currently inadequate and some infected patients may go undetected in the province. Remapping the regional distribution of HCV genotypes from time-to-time is required for identifying the local dynamics and causes leading to it. This process enhances the clinical preparation and readiness for the better management of the disease.

Abstract
Objective The present study was designed to analyse the effect of ST segment changes in aVR lead and the well-known risk factors in ST-segment elevated myocardial infarction (STEMI) patients. Materials and Methods A total of 250 patients who were admitted between 2009 and 2010 with STEMI and ≥1 mm ST-segment elevation in aVR lead were enrolled in the study. The patients were followed for life-threatening events like acute pulmonary oedema, atrial fibrillation, AV block, ventricular tachycardia, length of stay in hospital and death. Results Among the enrolled patients, 222 were discharged and 28 died. Pulmonary oedema and mortality rates were significantly higher in patients with ST-segment elevation in aVR lead (both p=0.001). Conclusions There is a correlation of ST-segment elevation in aVR lead with poor outcome in STEMI. Therefore aVR lead must be analysed as well as the other leads and well-known risk factors while it estimates the prognosis.

Abstract
BACKGROUND Ulcerative colitis (UC) is a chronic, inflammatory bowel diseases characterized by uncontrolled inflammatory condition of the colon and rectal mucosa marked by recurrent periods of remission and exacerbation. Vitamin D receptor (VDR) is a member of the steroid receptor family that mediates the effects of vitamin D by regulating transcription of multiple cellular genes. We aimed to evaluate vitamin d receptor level in biopsy specimen of patients with UC in this study. METHODS VDR levels were retrospectively studied in colon biopsy specimens of UC patients. The Spearman's rho correlation analysis, The Kolmogorov-Smirnov, Mann Whitney U, and chi-square tests were used for statistical analysis. The p values below 0.05 were considered statistically significant. RESULTS Study included 112 UC patients (65 male and 47 female) and 30 controls (19 female and 11 male) who had normal results in biopsy examinations carried out due to various reasons. VDR levels of UC patients were statistically lower than control subjects, and was not associated with duration of the disease and place of involvement. CONCLUSIONS VDR is an important receptor in the pathogenesis of UC, and optimizing vitamin D levels could have a therapeutic role in UC.

Abstract
PURPOSE To prospectively compare the diagnostic capabilities of quantitative susceptibility mapping (QSM) with those of phase images of susceptibility-weighted imaging (SWI) in the detection and differentiation of intracranial calcification and hemorrhage in pediatric patients. METHOD Sixteen pediatric patients (9 girls, 7 boys) with a mean age of 9.4±6.3 (SD) years (range, 6 days-15 years) were included. Fifty-nine calcifications and 31 hemorrhages were detected. Sensitivities and specificities of the two magnetic resonance (MR) imaging techniques were calculated and compared using McNemar test. RESULTS QSM had a sensitivity of 84.7% and specificity of 100% for the detection of calcification. SWI phase images had a sensitivity of 49.1% and specificity of 100%. For the detection of hemorrhage, QSM had a sensitivity of 90.3% and a specificity of 98.3% whereas SWI phase images yielded a sensitivity of 64.5% and specificity of 96.6%. Overall, QSM displayed significantly better sensitivity than SWI phase images in identification of calcification and hemorrhage (P<0.05). CONCLUSION QSM is more reliable than SWI phase images in the identification of intracranial calcification and hemorrhage in pediatric patients using MR imaging.

Abstract
OBJECTIVE Caloric restriction (CR) is proven to be effective in increasing life span and it is well known that, nutritional habits, sleeping pattern and meal frequency have profound effects on human health. In Ramadan some Muslims fast during the day-light hours for a month, providing us a unique model of intermittent fasting (IF) in humans. In the present study, we have investigated the effects of IF versus CR on the same non-diabetic obese subjects who were followed for two years according to the growth hormone (GH)/Insulin like growth factor (IGF)-1 axis and insulin resistance. DESIGN Single-arm Interventional Human Study. PARTICIPANTS 23 female subjects (Body Mass Index (BMI) 29-39, aged between 28-42years). SETTING Follow-up is designed as 12 months of CR, after which there was a month of IF and 11 months of CR again, to be totally 24 months. Subjects' daily diets were aligned as low calorie diet during CR and during the IF period, the same subjects fasted for 15 hours in a day for a month and there was no daily calorie restriction. Nutritional pattern was changed as 1 meal in the evening and a late supper before sleeping and no eating and drinking during the day light hours in the IF model. Subjects made brisk walking twice a day during the whole follow-up including both CR and IF periods. BMI, Blood glucose, insulin, TSH, GH, HbA1c, IGF-1, Homa-IR and urinary acetoacetate levels were monitored once in three months and twice in the fasting month. MEASUREMENTS AND RESULTS While subjects lost 1250 ± 372g monthly during the CR, in the IF period, weight loss was decreased to 473 ± 146 g. BMI of all subjects decreased gradually and as the BMI decreased, glucose, HbA1c, insulin, Homa-IR and TSH levels were decreased. GH levels were at baseline at the beginning, increased in the first six months and stayed steady during the CR and IF period than began decreasing after the IF period, while IGF-I increased gradually during the CR period and beginning with the 7th day of IF period, it decreased and kept on decreasing till the end of the follow-up. Urinary acetoacetate levels were higher during the IF period suggesting a constant lipid catabolism. CONCLUSION Our results suggest that, CR affects metabolic parameters positively which will help especially pre-diabetic and insulin resistant patients without any pharmacological approach. In addition IF without calorie restriction can enhance health and cellular resistance to disease without losing weight and those effects may be attributed to different signalling pathways and circulating ketones during IF. Changes observed during IF are probably due to the changes in eating and sleeping pattern and thus changes in metabolic rhythm.

Abstract
Drug-induced liver damage is a frequently encountered clinical table caused by many drugs. Cetirizine is a widely preferred and prescribed antihistaminic agent for allergic disorders due to its non-sedative properties. In view of the literature, we present four cases of hepatotoxicity due to cetirizine use. We conclude that in patients with high levels of liver enzymes of unknown origin, cetirizine as well as other hepatotoxic drugs should be reconsidered.

Abstract
OBJECTIVE To determine Blastocystis frequency and subtypes (ST) in ulcerative colitis (UC) patients and analyse some laboratory findings between Blastocystis positive and negative cases. METHODS Faecal samples from 150 UC patients in Adnan Menderes University, Training and Research Hospital were examined by direct microscopy and cultivated in Jones medium. Blastocystis positive cultures were subjected to DNA isolation and subtypes were identified by sequencing of barcode region. A retrospective analysis was conducted on C reactive protein (CRP), leucocyte counts (WBC), neutrophil counts, and sedimentation rates. RESULTS The overall positive rate of Blastocystis was 8% (12 patients) and the most abundant subtype was ST3 (eight isolates, 66.7%), followed by ST1, ST2 and ST7. Laboratory findings between Blastocystis infected and non-infected UC patients were not significantly different. Blastocystis frequency was 3.8% among the patients in active stage, while it was 11.8% among the patients in remission stage. CONCLUSIONS The present study confirms previous findings that have indicated the predominance of Blastocystis ST3 in humans and contributes additional evidence that suggests the low colonisation of Blastocystis infection in ulcerative colitis patients during active stage.

Abstract
OBJECTIVE Carbon monoxide (CO) poisoning is very common worldwide. Despite the fact that CO is known to have cardiotoxic effects, as it has non-specific symptoms; cardiotoxicity could easily be overlooked, especially when troponin is not measured. The present study aimed to evaluate the association between troponin I levels and red cell distribution width (RDW) levels, which can be measured rapidly, easily, and affordably in the Emergency Room (ER). PATIENTS AND METHODS This single-center observational study included a total of 504 consecutive patients, who presented to the ER due to CO poisoning between January 2011 and June 2015. The diagnosis of CO poisoning was made according to the medical history and carboxyhemoglobin (COHb) level of >5%. Elevated troponin test levels, which measure >0.04 ng/ml for our laboratory, were accepted as positive. RESULTS Patients (mean age 37±14) were classified into two groups: those who had positive troponin levels (38%) and those that did not. Patients with positive troponin, who were older, had longer CO exposure time and higher creatinine, COHb and RDW levels at the index admission following CO poisoning than patients with negative troponin. In a multivariate logistic regression model with forward stepwise method, age, COHb level, CO exposure time, and RDW (HR=1.681, 95% CI: 1.472-1.934, p<0.001) remained associated with an increased risk of troponin positivity following adjustment for the variables that were statistically significant in the univariate analysis and correlated with RDW. CONCLUSIONS In patients presenting to the ER with CO poisoning, RDW can be helpful for the risk stratification of troponin positivity.

Abstract
OBJECTIVE To investigate the relationship between dyspepsia symptom scores and endoscopic appearances, and histopathological findings and helicobacter pylori positivity in patients having dyspepsia symptom. METHODS The study was conducted at the gastroenterology outpatient clinic of Adnan Menderes University, School of Medicine, Aydin, Turkey from April 2012 to July 2012 and comprised patients between 18-65 years of age who were admitted with dyspepsia. Glasgow dyspepsia severity scoring was done with questions posed orally to the patients. In histopathological evaluation of biopsy specimens according to Sydney criteria, chronic inflammation, activity, atrophy, intestinal metaplasia and helicobacter pylori parameters were used. Total number of eosinophils and number of mast cells were recorded. RESULTS Of the 60 patients with dyspepsia, 38(63.3%) were female and 22(36.7%) were male. The degree of activation and severity of inflammation increased significantly with increasing helicobacter pylori positivity(r=0.459'p<0.0001; r=0.475'p<0.0001). A significant relationship was found between inflammation, activation and the number of mast cells (p<0.05).There was no relationship between helicobacter pylori intensity and the eosinophil count (r=0.171; p=0.093). There was also a statistically significant correlation between severity of inflammation and activation and the number of eosinophils (r=0.313;p=0.002;r=0.245;p=0.016). CONCLUSIONS Mast cell density was seen to have a role in the inflammatory processes of helicobacter pylori infection.

Abstract
PURPOSE The purpose of this study was to evaluate serum concentrations of human epididymis protein 4 (HE4) and cancer antigen 125 (CA 125) in healthy women and their pregnant counterparts to determine the influence of pregnancy on these biomarkers. MATERIALS AND METHODS Serum concentrations of CA 125 and HE4 were measured in 27 healthy non-pregnant women and 26 healthy pregnant women in the first and second trimesters. RESULTS Higher concentration of CA 125 was found in pregnants than in non-pregnant women (p = 0.002). There was no difference in CA 125 concentrations between first and second trimesters (p = 0.13). Serum HE4 concentration was not different in pregnant group compared to non-pregnant women (p = 0.510). Likewise, no difference was found in HE4 levels between the trimesters (p = 0.485). There was a positive correlation between increasing parity and CA 125 (p = 0.023), but not HE4 (p = 1.0). CONCLUSION HE4 serum biomarker is unaffected by pregnancy status and may be useful for evaluation of doubtful pelvic masses in pregnancy. Contrarily, increased serum levels of CA 125 could yield increased number of false-positive results.

Abstract
OBJECTIVES Estrogen could affect the rate and quality of wound healing in skin. We aimed to investigate the effects of ovariectomy on skin flap viability and myeloperoxidase (MPO) levels in a rat model. BACKGROUND Estrogens have many important beneficial and protective roles in skin that they improve collagen content and quality, maintain skin thickness and enhance vascularization. It has been shown that estrogen supplementation accelerates cutaneous wound healing in elderly patients. METHODS Forty-eight cycling female Wistar albino rats were randomly divided into three groups (n = 16); ovariectomy (Group 1), sham (Group 2), and control (Group 3). Rats were subjected to bilateral ovariectomy in the Group 1, and only laparotomy in the Group 2. Twenty-one days later in the Group 1 and 2, a dorsal caudally based skin flap elevation was done. In the Group 3, the rats had a dorsal skin flap without any surgical intervention. Ten days later, the flaps were harvested for histopathologic examination and biochemical analyses. RESULTS The rats in the Group 1 had significantly larger necrotic area and lower flap viability than in the Group 2 and 3 (p<0.05). Histopathologic examination showed that necrotic flap regions contained muscle necrosis with an abundant neutrophil infiltration, and severe edema in the Group 1. The MPO activity in the distal of skin flaps was significantly higher in the Group 1 compared to the Group 2 and 3 (p<0.05). CONCLUSION This study shows that ovariectomy has deleterious effects on skin flap viability in a rat model (Tab. 1, Fig. 6, Ref. 44).

Abstract
AIM Laparoscopy is the gold standard procedure in the surgery of gall bladder. Harmonic scalpel and bipolar vessel sealer are the other instruments for laparoscopic cholecystectomy. The aim of this study is to compare the effectiveness and safety of the three instruments for laparoscopic cholecystectomy. METHODS A total of 60 patients were included into the study. Patients were divided into three groups. In Group A, cystic duct and artery were sealed using laparoscopic clips and gall bladder was dissected from the hepatic bed using electrocautery. In Group B, cystic duct and artery were sealed using Harmonic scalpel and gall bladder was dissected from the hepatic bed using Harmonic scalpel. In Group C, cystic duct and artery were sealed using Bipolar vessel sealer and gall bladder was dissected from the hepatic bed using Bipolar vessel sealer. Groups were compared for the following parameters: duration of surgery, amount of drainage, cystic duct opening pressure and cost. RESULTS The duration of surgery was 31.5 ± 11.1 minutes in Group B, 33.1 ± 10 minutes in Group A, and 36.5 ± 9.9 in Group C; and the difference between Group B and Group C was statistically significant (P<0.04). Cystic duct opening pressure was highest in Group A which was 324.0 ± 23.4 mmHg. For all of these 3 groups total cost was found to be 900$, 2900$, 1800$ for groups A, B, and C; respectively. CONCLUSION In laparoscopic cholecystectomy different energy source instruments may be safe to use with a cautious dissection and sealing of the cystic duct.

Abstract
A 43-year-old woman was first admitted to the ophthalmology clinic with the complaint of a mass compressing the right eye. Based on clinical and laboratory examinations she was diagnosed as having marginal zone lymphoma (MZL) of the right lacrimal gland in addition to hepatitis C virus (HCV) infection. After the treatment for HCV infection with pegylated interferon plus ribavirin, a radiographic response of the MZL was obtained; she remains in remission through thirty months of clinical follow-up. In this case, the treatment of HCV infection led to regression of MZL suggesting the necessity of testing for HCV infection and treatment of the HCV infection should be highly considered in all HCV-positive patients with MZL's.

Abstract
BACKGROUND There has been increased interest in measuring the serum concentration of acute phase reactants such as serum amyloid A [SAA] and haptoglobin [haptoglobin] in periparturient cattle in order to provide a method for detecting the presence of inflammation or bacterial infection. OBJECTIVES To determine whether [SAA] and [haptoglobin] are increased in cows with displaced abomasum as compared with healthy dairy cows. ANIMALS Fifty-four adult dairy cows in early lactation that had left displaced abomasum (LDA, n = 34), right displaced abomasum or abomasal volvulus (RDA/AV, n = 11), or were healthy on physical examination (control, n = 9). MATERIALS AND METHODS Inflammatory diseases or bacterial infections such as mastitis, metritis, or pneumonia were not clinically apparent in any animal. Jugular venous blood was obtained from all cows and analyzed. Liver samples were obtained by biopsy in cattle with abomasal displacement. RESULTS [SAA] and [haptoglobin] concentrations were increased in cows with LDA or RDA/AV as compared with healthy controls. Cows with displaced abomasum had mild to moderate hepatic lipidosis, based on liver fat percentages of 9.3 +/- 5.3% (mean +/- SD, LDA) and 10.8 +/- 7.7% (RDA/AV). [SAA] and [haptoglobin] were most strongly associated with liver fat percentage, r(s) = +0.55 (P < .0001) and r(s) = +0.42 (P = .0041), respectively. CONCLUSIONS AND CLINICAL IMPORTANCE An increase in [SAA] or [haptoglobin] in postparturient dairy cows with LDA or RDA/AV is not specific for inflammation or bacterial infection. An increase in [SAA] or [haptoglobin] may indicate the presence of hepatic lipidosis in cattle with abomasal displacement.

Abstract
OBJECTIVE To discuss a fetus with craniorachischisis diagnosed antenatally and to review the literature. METHOD Case report. RESULTS Craniorachischisis was detected on ultrasound scan in a fetus at gestational week 13. Pregnancy was terminated and diagnosis was verified postnatally. CONCLUSION Craniorachischisis is a rare and severe form of neural tube defects (NTDs). The majority of currently known cases of mouse craniorachischisis have been found to result from disturbance of a single molecular signaling cascade, called planar cell polarity pathway (PCP). The mutant genes that have been causative in disturbance of PCP in mouse models have been examined in human malformations but none of them have so far been implicated in human craniorachischisis. To date, no other genes except the gene encoding 5,10-methylenetetrahydrofolate reductase have been specifically implicated in predisposition to NTDs. We suggest that other PCP genes should be considered as candidates for a role in the etiology of human NTDs. Further investigations are therefore necessary.

Abstract
OBJECTIVE To investigate serum levels of CA 19.9, CA 125 and carcinoembryonic antigen (CEA) in patients with different stages of chronic obstructive pulmonary disease (COPD). PATIENTS AND METHODS Fifty-three consecutive patients (50 males, 3 females, mean age 67.6 +/- 10.1 years) with COPD were included in this study. Serum levels of CA 19.9, CA 25 and CEA were determined by the chemiluminescent immunometric method. Based on values obtained from pulmonary function tests, the patients were divided into 3 groups: moderate (21), severe (18) and very severe (14). Data were analyzed with a Kruskal-Wallis one-way analysis of variance test and Mann-Whitney U test. RESULTS The mean serum levels of CA 125 and CA 19.9 were significantly higher in patients with very severe COPD (p = 0.013 and p = 0.017, respectively) than in patients with severe and moderate COPD (p < 0.05). Patients with cor pulmonale had significantly high mean serum levels of CEA, CA 19.9 and CA 125 (p < 0.05). Patients using a long-acting beta-agonist and theophylline showed significantly higher mean serum levels of CA 125 than patients who were not (p < 0.05). CONCLUSION Data showed that the increased serum tumor markers in patients with COPD might be due to the severity of COPD, medication and cor pulmonale.

Abstract
We report here a case with microcephaly, preauricular pits, cleft lip-palate, hypertelorism, multiple frenula and preaxial polydactyly. The clinical picture overlaps with many syndromes, but it is mostly consistent with oral-facial-digital syndrome, Gabrielli type. There are no previously reported cases of this syndrome presenting also with microcephaly. On the other hand, it is hard to differentiate this clinical picture from Goldenhar syndrome (Oculo-auriculo-vertebral spectrum), and oculo-auriculo-fronto-nasal syndrome because of many overlapping features.

Abstract
Hyperprolactinemia is the most common pituitary hormone hypersecretion syndrome in both men and women. Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathies affecting 5%-10% of reproductive age women. Here, we present a patient with irregular menses, obesity, hirsutism and infertility, and hyperprolactinemia who was diagnosed as PCOS and prolactinoma and admitted to our clinic. Prolactinoma and PCOS association is a rare condition. This 33-year-old woman was admitted to the internal medicine outpatient clinic for irregular menses, obesity, hirsutism and infertility, and hyperprolactinemia. Her laboratory results were as follows: prolactin was 74 ng/mL (normal range:1.8-20.3 ng/mL). Pelvic ultrasonography was correlated with polycystic ovary syndrome. Pituitary MRI showed 6x8 mm microadenoma at left half. Bromocriptine was started with 1.25 mg/day and increased to 5 mg/day. After six months of bromocriptine treatment her prolactin level was normal and no adenoma was detected in pituitary MRI. PCOS and prolactinoma association should be taken into account in PCOS cases with mild hyperprolactinoma.

Abstract
This is the first report of Guillain-Barré syndrome (GBS) related to Legionnella pneumophilia infection. A 13-year-old boy presented with acute dysphagia and dyspnea. He lived in a rural area and had a history of drinking potable deep-hole water. The patient was intubated because of increased respiratory distress. A positive direct fluoresein antigen test confirmed L. pneumophilia infection in BAL. One week after the first admission, acute weakness was noticed including the lower extremities and was more prominent in the distal than the proximal portions. GBS was considered as the initial diagnosis. Tests for all causes known to trigger GBS were negative. Specific serology for L. pneumophilia IgG was positive. He was treated with intravenous immunoglobulins and discharged with minor weakness and difficulty in walking in the second month. On the basis of this case, L. pneumophilia should be included in the etiologic spectrum of GBS.

Abstract
Leiomyomas and diffuse uterine leiomyomatosis are smooth muscle tumors of the uterus. Diffuse uterine leiomyomatosis is a benign and extremely rare condition in which the uterus is symmetrically enlarged as a result of the almost complete replacement of the myometrium by innumerable poorly defined, confluent nodules. The etiology of these neoplasms is not completely understood. Initial symptoms of the diffuse uterine leiomyomatosis usually are abdominal pain and abnormal uterine bleeding. Similar to uterine leiomyomas, patients with leiomyomatosis present with menorrhagia, dysmenorrhea, abdominal pain, infertility, and pelvic pressure. Hormonal treatment usually fails to control the symptoms, anemia, or tumor growth after treatment is stopped. As a result, despite patients being in the third or fourth decades of life, hysterectomy has been the only permanent treatment option offered to patients for treatment of the symptoms related to uterine fibroids in diffuse leiomyomatosis. A case of a patient with a huge uterine mass (2,650 g in weight) who underwent hysterectomy due to diffuse uterine leiomyomatosis is presented together with a review of the literature.

Abstract
We are presenting a prenatally diagnosed case with sirenomelia, vestigial tail and polydactyly. A 30-year-old woman at 16 weeks of gestation with dichorionic twins was admitted to the hospital. Prenatal ultrasound demonstrated fusion of the lower limbs in one member and normal femurs, tibias and fibulas, and normal vertebras in the second twin, suggesting the diagnosis of sirenomelia. The twins were delivered vaginally at 35 weeks after spontaneous onset of labor. The affected newborn died after 24 hours and postnatal examination revealed unseparated lower limbs with extreme retroversion, bilateral pes equinus, unilateral postaxial polydactyly, a vestigial tail on the sacral region, a large and wide penis and anal atresia. There is only one previous report of sirenomelia with vestigial tail in the literature. However, a large, wide penis and polydactyly have not been reported before in association with this anomaly.

Abstract
PURPOSE To evaluate the importance of CA-19-9 as an aiding tool in the diagnosis of mature cystic teratomas. METHODS We found 43 cases of dermoid cysts that were operated on at our clinic, and whose tumor marker CA 19-9 was studied before the operation. RESULTS Thirty-seven of 43 patients (86%) had elevated CA 19-9 levels. Using Pearson's correlation, the average diameter and weight of the tumor had a strong possitive correlation with the level of CA 19-9 (p < 0.01). Thirty-one out of the 43 (72%) cases had a dermoid cyst in the right ovary, nine (20.9%) in the left ovary, and three (7%) had bilateral dermoid cysts. Right predominancy was very high among the patients (p < 0.05). CONCLUSION We suggest that besides ultrasonography and computed tomography, serum CA 19-9 level could be a useful tumor marker in the diagnosis of dermoid cysts.

Abstract
Infantile hemangioendothelioma is the third most common hepatic tumor in children, and the most common benign vascular tumor of the liver in infancy. On computed tomography (CT) and magnetic resonance imaging (MRI), typical enhancement patterns similar to those seen in adult hemangiomas may help establish the diagnosis. However, atypical enhancement patterns may also occur. In this paper, we report a rare form of solitary infantile hemangioendothelioma that showed a rim-like calcification and rim-like enhancement on CT and MRI.

Abstract
OBJECTIVE To investigate whether Chlamydia pneumoniae (Cpn) seropositivity in patients with suspected coronary artery disease (CAD) (n = 81) is associated with increases in markers of inflammation, the severity of coronary atherosclerosis, and traditional risk factors for cardiovascular events. MATERIAL AND METHODS The severity of coronary atherosclerosis was ranked by Gensini score. Inflammation and endothelial dysfunction were evaluated using white blood cell counts and levels of high-sensitivity C-reactive protein (hs-CRP), ferritin, tumour necrosis factor-alpha (TNF-alpha), interleukins 1beta and 6 (IL-1beta, IL-6), soluble intercellular adhesion molecule-1 (sICAM-1), E-selectin and oxidized LDL (oxLDL), and these were compared between Cpn-seropositive and seronegative individuals. RESULTS IgA and IgG Cpn seropositivity were significantly associated with the presence of CAD (p = 0.005) and were independent predictive factors for the severity of coronary atherosclerosis (p = 0.005). Elevated levels of IL-6 (p = 0.027) and triglyceride (p = 0.038) and low levels of high-density lipoprotein cholesterol (HDL-C) (p = 0.038) were significantly predicted by Cpn IgA and IgG seropositivity. CONCLUSIONS Seropositivity for Cpn is a risk factor for patients with significant angiographically documented coronary stenosis. Additionally, Cpn seropositivity was significantly associated with dyslipidemia and elevated IL-6, known risk factors for CAD. These observations indicate that Cpn infection may be one entry point to the causal or contributory pathways that lead to atherosclerosis and its clinical manifestations.

Abstract
OBJECTIVE We aimed at treating complicated pilonidal sinus (PS) patients by a simple and effective surgical procedure. METHOD Between 2000 and 2004, 24 selected complicated PS patients were treated with 'limited separate elliptical excision and primary closure'. Patients with extensive or bilateral gluteal involvement, having more lateral, caudal or cephalic sinuses, multiple recurrences and unhealed chronic wounds after pilonidal surgery were included. Asymmetric excision and primary closure was performed to main diseased tissue in the midline. Additionally, small separate elliptical excisions with primary closure were performed in other involved tissues. The fistula tract or granulation tissue were excised subcutaneously if present. All patients were operated under local anaesthesia. The fascial attachments between the skin and coccyx were released at the deep point in the midline and at one side of wound. Suction drains and prophylactic antibiotics were used; subcutaneous tissues were closed with running polyglactin sutures and skin with polypropylene subcutaneously. RESULTS The mean age of patients was 28.4 years (range 18-38). The mean follow-up time was 2.8 years. One recurrence, one seroma, one wound infection and one wound breakdown were recorded. Healing was always by first intention except in patients with wound infection and breakdown. CONCLUSION Most of the complicated PS patients can be operated with acceptable rates of recurrences and complications by using 'limited separate elliptical excisions with primary closure'.

Abstract
The purpose of this study was to determine concentrations of serum glucose, aspartate aminotransferase (AST), insulin, beta-hydroxybutyrate (BOH) and ionised calcium (Ica) in dairy cows with left displaced abomasum (LDA) and to compare these parameters before and after surgical correction of LDA. Eighteen Swiss-Holstein dairy cows with LDA were used in this study. Clinically healthy post parturient cows (n: 10) from a local dairy farm were used as control group. Blood samples were collected from the jugular vein from all the cows. Surgery was performed in cows with LDA. Blood samples from cows with LDA were collected 24 hours after surgery. The abomasum was repositioned followed by an omentopexy. Six of the 18 cows with LDA had clinical ketosis as detected with urine dipstick. The mean concentrations of insulin, BOH, glucose and AST in cows with LDA at admission time were increased compared with the healthy cows. But the mean concentration of ICa at admission time was slightly decreased compared with healthy cows. The mean BOH concentration was decreased 24 hours following surgery compared with values on admission time. However, the mean serum AST levels were increased both at admission time and 24 hours after surgery compared with healthy cows. The levels of blood gas parameters in cows with LDA were not significantly different in comparison with healthy cows, although hyperbasemia in six of 18 cows with LDA was determined. In conclusion, the results of this study indicated that serum insulin, glucose, AST and BOH levels were increased in dairy cows with LDA. Serum BOH and ICa levels were decreased 24 hours after surgery compared with values on admission time. All cows with LDA used in this study had subclinical/clinical ketosis. We could say that ketosis might be a risk factor for the displacement of the abomasum.
