Abstract
OBJECTIVE In this study, we aimed to evaluate the characteristics of pediatric rhupus patients including all the related series in the literature. METHODS Thirty pediatric patients with rhupus syndrome from 12 different centers in Turkey were included in this study. The literature was also reviewed for pediatric patients with rhupus syndrome. RESULTS The most prominent phenotype of these 30 patients was juvenile idiopathic arthritis (JIA) (60%) at the disease onset and SLE (73.3%) at the last visit. Major SLE-related organ involvements were skin (80%), hematological system (53.3%), and kidney (23.3%). Arthritis was polyarticular (73.3%), asymmetric (66.7%), and erosive (53.3%) in most patients. Hydroxychloroquine (100%), glucocorticoids (86.7%), and mycophenolate mofetil (46.7%) were mostly used for SLE, while glucocorticoids (76.6%), methotrexate (73.3%), and nonsteroidal anti-inflammatory drugs (NSAIDs) (57.6%) were mainly preferred for JIA. Our literature search revealed 20 pediatric patients with rhupus syndrome (75% were RF positive). The most prominent phenotype was JIA (91.7%) at the disease onset and SLE (63.6%) at the last visit. Major SLE-related organ involvements were skin (66.7%), hematological system (58.3%), and kidney (58.3%). Arthritis was polyarticular (77.8%), asymmetric (63.6%), and erosive (83.3%) in most patients. Glucocorticoid (100%), hydroxychloroquine (76.9%), and azathioprine (46.2%) were mostly used for SLE, while methotrexate (76.9%) and NSAIDs (46.2%) were mainly preferred for the JIA phenotype. CONCLUSION Our study is the largest cohort in the literature evaluating pediatric rhupus cases. Most of the pediatric patients had polyarticular, asymmetric, and erosive arthritis, as well as organ involvements associated with SLE, including the skin, hematological system, and kidney.

Abstract
To develop a better understanding of 'in-service' performance of modern marine coatings, this study explored the combined effects of different roughness ranges of foul-release coating (FRC) and light biofouling (slime) on the surface, boundary layer and drag characteristics under a range of 'in-service' conditions. Natural and laboratory biofilms were grown dynamically on FRC panels by exposing panels in facilities dedicated to realistic fouling culture. The boundary layer experiments were conducted in a circulating water tunnel. Boundary layer similarity-law scaling was used to predict the combined effects of coating roughness and biofilms on the added frictional resistance (% ΔCF) and added required effective power (%ΔPE ) for a benchmark KRISO container ship (KCS) and a bulk carrier. The increase in %ΔPE due to the presence of biofilms on commercial FRC is estimated to be between 7% and 16% depending on the biofilm type, biofilm thickness and percentage coverage. Significant increases in effective power are estimated for non-fouling control primers with heavy fouling. Moreover, the paper suggests updated roughness allowances ( ΔCF ) for two vessel types assuming FRCs on their hulls with more representative hull roughness ranges and fluffy biofilms.

Abstract
OBJECTIVE To assess pain symptoms before and after hysterectomy in women with endometriosis. DESIGN A population-based registry study. SETTING Sweden. POPULATION Women aged 18-45 years who underwent hysterectomy for endometriosis between 2010 and 2015. METHODS Pain symptoms before hysterectomy and 12 months after surgery were collected from the Swedish National Quality Register for Gynaecological Surgery (GynOp). Pain symptoms were also assessed by follow-up surveys after a median follow-up period of 63 months. MAIN OUTCOME MEASURES Pelvic or lower abdominal pain after hysterectomy. RESULTS The study included 137 women. The proportion of women experiencing pain of any severity decreased by 28% after hysterectomy (P < 0.001). The proportion of women with severe pain symptoms decreased by 76% after hysterectomy (P < 0.001). The majority of women (84%) were satisfied with the surgical result. Presence of severe pain symptoms after the hysterectomy was associated with less satisfaction (P < 0.001). Pain symptoms after surgery, patient satisfaction and the patient's perceived improvement were not significantly different between women whose ovarian tissue was preserved and women who underwent bilateral oophorectomy. CONCLUSIONS We observed a significant, long-lasting reduction in pain symptoms after hysterectomy among women with endometriosis. Hysterectomy, with the possibility of ovarian preservation, may be a valuable option for women with endometriosis who suffer from severe pain symptoms. TWEETABLE ABSTRACT Hysterectomy is a valuable option for women with endometriosis and severe pain symptoms.

Abstract
Objective To demonstrate whether there is an association between jugular venous reflux and nonpulsatile subjective tinnitus (NST) using real-time four-dimensional magnetic resonance imaging (MRI) angiography. Materials and Methods Patients with unilateral NST who underwent contrast-enhanced MRI with a special protocol were included in the study. Thick slab dynamic maximum intensity projection images were obtained including interleaved stochastic trajectories (TWIST)-MRI examination. All patients were requested to perform Valsalva maneuver during the sequence. Jugular venous reflux grading was performed as follows: absence of reflux or if reflux does not reach the base of the skull: grade 0; if reflux reaches the jugular bulb, but no intracranial contrast is observed: grade 1; and if reflux extends into the intracranial cortical veins and/or the cavernous sinus above the jugular bulb: Grade 2. Results A total number of 30 patients, 23 male and 7 female, were included in the study. Jugular venous reflux was not identified (Grade 0) in 20 patients. Grade 1 reflux was determined in 7 cases and Grade 2 reflux was observed in 3 cases. Notably, only patients with Grade 2 reflux described worsening of their tinnitus symptoms during the examination and their daily activities as well. Conclusions NST might also be associated with hemodynamic problems of the venous system and the MRI protocol starting with TWIST accompanied with Valsalva maneuver is not well-known, yet seems to be a feasible and beneficial method to detect potential jugular venous reflux in NST patients.

Abstract
Abstract
STUDY QUESTION
Does the long-term fecundity of women with polycystic ovary syndrome (PCOS) differ from those without PCOS?
SUMMARY ANSWER
Cumulative probability of childbirth is similar between women with and without PCOS.
WHAT IS KNOWN ALREADY
PCOS is the main cause of anovulatory infertility in women after menarche. Previous studies indirectly suggest that fecundity in women with PCOS over the longer term may not be lower than in women without PCOS.
STUDY DESIGN, SIZE, DURATION
This is a population-based study using four linked Swedish national registries. A total of 45 395 women with PCOS and 217 049 non-PCOS women were included. Follow-up began at the age of 18 years and continued for a maximum of 26 years, from 1989 to the end of 2015. Childbirth was the main outcome, as identified from the Medical Birth Register.
PARTICIPANTS/MATERIALS, SETTING, METHODS
All women born between 1971 and 1997 who were identified with a PCOS diagnosis in the Swedish Patient Registry between 1 January 2001 and 31 December 2016 were included in the study population. Five controls per women with PCOS were randomly drawn from the Total Population Registry. The control women were born in the same year and living in the same municipality as the patient. The fecundity ratio (FR) was calculated by clustered Cox regression using a robust variance, adjusted for maternal birth period, country of birth and level of education.
MAIN RESULTS AND THE ROLE OF CHANCE
The cumulative probability of childbirth was 80.2% (95% CI, 79.5–80.9%) in women with PCOS and 78.2% (95% CI, 77.9–78.5%) in those without PCOS. Adjusted FR was 0.81 (95% CI, 0.80–0.82) for first childbirth and 0.58 (95% CI, 0.57–0.60) for first childbirth following a spontaneous pregnancy. The FR for second childbirth was 0.79 (95% CI, 0.77–0.80). Women with PCOS had more than one child less frequently than the comparison group. Within the PCOS group, early age at diagnosis, later birth year, Nordic country of origin and low educational level positively influenced the FR.
LIMITATIONS, REASONS FOR CAUTION
Results are not adjusted for BMI, and time from intention to conceive to first childbirth could not be captured. Data on pregnancies, miscarriages or abortions and fertility treatment are unknown for women who did not give birth during the study period. Women with PCOS who did not seek medical assistance might have been incorrectly classified as not having the disease. Such misclassification would lead to an underestimation of the true association between PCOS and outcomes.
WIDER IMPLICATIONS OF THE FINDINGS
While cumulative probability of childbirth is similar between groups, women with PCOS need longer time to achieve their first childbirth. Women with PCOS have a lower FR and give birth to fewer children per woman than women without PCOS. Early diagnosis of and information about PCOS may improve affected women’s reproductive potential.

Abstract
Obesity is strongly associated with ill health, primarily caused by consumption of excessive calories, and promoted (inter alia) by gamma-amino-butyric-acid (GABA) stimulating food intake by activating GABAA receptors (primarily with α3 and α2 subunits) in the hypothalamic arcuate nucleus and paraventricular nucleus. Allopregnanolone is a potent positive GABAA receptor modulating steroid (GAMS). As reviewed here, elevated allopregnanolone levels are associated with increases in food intake, preferences for energy-rich food, and obesity in humans and other mammals. In women with polycystic ovarian disease, high serum allopregnanolone concentrations are linked to uncontrolled eating, and perturbed sensitivity to allopregnanolone. Increases in weight during pregnancy also correlate with increases in allopregnanolone levels. Moreover, Prader-Willis syndrome is associated with massive overeating, absence of a GABAA receptor (with compensatory >12-, >5- and >1.5-fold increases in α4, γ2, and α1, α3 subunits), and increases in the α4, βx, δ receptor subtype, which is highly sensitive to allopregnanolone. GABA and positive GABA-A receptor modulating steroids like allopregnanolone stimulates food intake and weight gain.

Abstract
OBJECTIVE We aimed to investigate the effect of mad honey on sexual performance. BACKGROUND In traditional medicine in Turkey, mad honey is used to improve appetite, to heighten mental alertness, to reduce joint pain, to eliminate gastrointestinal system pains and to increase sexual performance. METHODS In this experimental animal study eighteen Sprague Dawley male rats were randomized into three groups, a control group, a normal honey group and a mad honey group. Rats in the treatment groups were given a daily dose of 80 mg/kg normal honey or mad honey throughout the 30-day study period. Total testosterone, free testosterone, FSH, LH, estradiol, and progesterone levels were subsequently investigated from blood sera on day 30. RESULTS Comparison of blood total testosterone levels among the groups revealed significantly higher levels in the mad honey group compared to the normal honey and control groups (p = 0.006, p = 0.00). Free testosterone levels were also significantly higher in the mad honey group than in the normal honey and control groups (p = 0.023, p = 0.01). No statistically significant differences were determined for other hormonal measurements. CONCLUSIONS This study revealed a significant increase in both total and free testosterone levels in mad-honey group (Tab. 1, Fig. 2, Ref. 16).

Abstract
BACKGROUND Acute intermittent porphyria (AIP), a life-threatening form of the disease, is accompanied by several pain, mental and physical symptoms. AIMS In this study, we evaluated the cyclicity of AIP and premenstrual syndrome (PMS) symptoms in 32 women with DNA-diagnosed AIP during their menstrual cycles, in northern Sweden. METHODS The cyclicity of AIP symptoms and differences in them between the follicular and luteal phases, and the cyclicity of each symptom in each individual woman in different phases of her menstrual cycle were analysed with a prospective daily rating questionnaire. PMS symptoms were also evaluated in the patients on a daily rating scale. RESULTS Of the 32 women, 30 showed significant cyclicity in at least one AIP or PMS symptom (P < 0.05-0.001). Back pain (10/32) was the most frequent AIP pain symptom and sweet craving (10/15) was the most frequent PMS symptom. Pelvic pain (F = 4.823, P = 0.036), irritability (F = 7.399, P = 0.011), cheerfulness (F = 5.563, P = 0.025), sexual desire (F = 8.298, P = 0.007), friendliness (F = 6.157, P = 0.019), breast tenderness (F = 21.888, P = 0.000) and abdominal swelling (F = 16.982, P = 0.000) showed significant cyclicity. Pelvic pain and abdominal swelling (rs = 0.337, P < 0.001) showed the strongest correlation. The age of women with latent AIP was strongly correlated with abdominal swelling during the luteal phase (rs = 0.493, P < 0.01). CONCLUSION Our results suggest that the symptoms of AIP patients change during their menstrual cycles.

Abstract
AIM Coronary artery ectasia (CAE), is at least 1.5 fold dilatation of at least one coronary segment due to congenital or acquired causes. In this study, we aim to investigate the relation of CAE with microalbuminuria, which is a marker of endothelial dysfunction shown to be associated with increased cardiovascular mortality and morbidity. PATIENTS AND METHODS Patients with CAE detected during routine coronary angiogram (CAG) and individuals with normal CAG findings have been included in our study. Urine albumin levels were measured by immunoturbidimetric method from samples collected in the morning. Patients with an albumin/creatinine (A/C) ratio less than 0.03 were normal and the ones between values 0.03-0.3 were considered to be microalbuminuric. Patients whose A/C ratios > 0.3 had macroalbuminuria and were excluded. RESULTS A total of 105 patients (60 with CAE and 45 with normal CAG) were included in the study. Serum creatinine, low-density lipoprotein cholesterol and homocysteine levels were increased in the CAE group. Urine A/C ratio was 0.036 ± 0.040 in the CAE group and 0.018 ± 0.013 in the controls; the difference was statistically significant (p = 0.002). CONCLUSIONS Blood homocysteine levels and urinary albumin levels are significantly increased in patients with CAE when compared to individuals with normal CAG. Microalbuminuria and hyperhomocysteinemia, two markers of endothelial dysfunction might be associated with pathophysiologic processes leading to CAE.

Abstract
AIM To study signs of diabetic cardiomyopathy (DCM) in nondiabetic patients with controlled arterial hypertension (AH) and glycemic response during first hour of glucose tolerance test (GTT). MATERIAL AND METHODS Patients (n = 47) with controlled AH were divided into 2 groups according to results of GTT with 75 g of glucose: patients of group 1 (n = 22) had glucose level ≤ 200 mg/dl during 1-st hour of GTT; other patients (n = 25) composed group 2. Examination of all patients included transthoracic echocardiography, ultrasound Dopplerography, tissue Doppler (TD) and 24-hour Holter ECG monitoring. Using data of these methods we calculated left ventricular (LV) mass and the following characteristics of mitral ring: E/A, TD e', TD a', TD s', TD e'/a'/. The following characteristics of heart rate variability were obtained: standard deviation of normal RR intervals (SDNN), low and high frequency (LF, HF) power, LF/HF ratio. RESULTS Patients of group 2 had higher LV mass (229.5 ± 58.2 vs. 192.1 ± 50.6 g; p = 0.036), more pronounced changes of TD e'/a' (0.71 ± 0.25 vs. 1.06 ± 0.58; p = 0.011), lower SDNN both during day (85.4 ± 14.1 vs. 112.5 ± 31.3 ms, p = 0.007) and night (82.2 ± 22.1 vs. 105.9 ± 28.5 ms, p = 0,004) time, higher nocturnal LF/HF ratio (3.75 ± 4.02 vs. 1.72 ± 0.81, p = 0,029). CONCLUSION In patients with controlled arterial hypertension (AH) and glycemic response during first hour of GCT we revealed various pronounced manifestations of DCM. These data constitute a basis for further studies.

Abstract
OBJECTIVES ST segment elevation myocardial infarction (STEMI) is an important cause of the morbidity and mortality in coronary artery disease. The aim of this study is to investigate the relationship between hematologic parameters and post primary PCI coronary no-reflow. PATIENTS AND METHODS A total of 145 consecutive STEMI patients (mean age=58.2±12.3 years) and healthy volunteer admitted within 6 hours from symptom onset were enrolled to the study in the cardiology clinics. The STEMI patients were divided into 2 groups based on the Thrombolysis In Myocardial Infarction (TIMI) flow grade. No-reflow was defined as post-PCI TIMI Flow Grade 0, 1 or 2 and angiographic success was defined as TIMI Grade 3 Flow. RESULTS Diabetes mellitus hypertension and smoking status were similar between groups. With respect to baseline laboratory status, fasting glucose, blood urea nitrogen, creatinine levels were not significantly different between groups. The neutrophil/lymphocyte (N/L) ratio was also significantly higher in STEMI group (7.1±4.6 vs. 2.3±1.7, p < 0.001). Additionally, N/L ratio was also significantly higher in No-reflow group (TIMI Flow Grade 0, 1 or 2) group (13.1±4.5 vs. 5.3±2.7, p < 0.001). CONCLUSIONS The N/L ratio, which is cheaply and easily measurable laboratory data is independently associated with post primary PCI coronary no-reflow.

Abstract
Objectives: The aim of this experimental study was to investigate the effects of mad honey (grayanotoxin, GTX), used in complementary medicine for a variety of purposes besides being food, on pain thresholds in normal mice as model for acute pain and diabetic mouse as model for neuropathic pain. Methods: Hind paw withdrawal pain threshold to thermal stimulus was measured with a plantar analgesia meter in a mice model using healthy intact animals for acute pain and streptozotocin-induced diabetic animals for chronic neuropathic pain. Time and dose-dependent effects of intraperitoneally (i.p.) administered GTX were investigated in both acute and neuropathic pain. Results: In the acute pain model, administration of GTX caused a dose- and time-dependent marked increase in the pain latency values. In diabetic mice, which had markedly increased threshold to pain, GTX (0.1 mg/kg, i.p.) restored the mean pain latencies by decreasing from the pre-GTX treatment values of 3.2 ± 0.6 to 3.0 ± 0.9s at 10 min, 3.2 ± 0.6s at 20 min, 3.4 ± 0.6s at 30 min, 2.6 ± 0.5s at 60 min and 2.4 ± 0.6s ( p < 0.05) at 100 min. Conclusion: The results from this experimental study indicate that GTX exhibits significant analgesic activity and has potential benefits against painful diabetic neuropathy. This is compatible with the widespread use of GTX containing mad honey for alleviating pain. Further studies involving long-term applications are needed for a more decisive conclusion regarding the usefulness of GTX as an analgesic, especially in the treatment of painful neuropathy.

Abstract
Aim of the study was assessment of prognostic value of exercise myocardial perfusion scintigraphy in patients with stable and unstable angina in whom revascularization by percutaneous coronary intervention (PCI) was incomplete and at least one chronic total coronary artery occlusion (CTO) remained after PCI. Between March 2002 and December 2007 569 consecutive patients with multivessel lesions were subjected to SPECT imaging of myocardial perfusion after incomplete revascularization of the myocardium by PCI. At least 1 residual CTO was found in 129 patients (79% men, mean age 64+/-8 years). Primary outcomes were defined as cardiac death or myocardial infarction. Secondary outcomes were registered in 10 (7.9%) and 15 (11.9%) patients, respectively, with moderate and large transitory disturbances of perfusion. Logarithimic range criterion was statistically significant in patients distributed to groups by total estimation of rest in relation to cardiac complications. Univariate and multivariate Cox proportional hazards regression analysis gave additional important information for prediction of severe and nonsignificant cardiac complications when scintigraphic data were added to angiographic and clinical data, left ventricular ejection fraction, and results of treadmill test. Early monitoring with the use of myocardial scintigraphy by SPECT method is associated with increasing prognostic value relative to severe cardiac complications in patients subjected to incomplete revascularization by PCI, and having at least one residual chronic total occlusion.

Abstract
Aim of this multicenter retrospective study was assessment of effect of intracoronary administration of tirofiban loading dose in troponin positive patients with acute coronary syndrome (ACS). We analyzed multicenter data base of patients subjected to percutaneous coronary interventions (PCI) because of ST-elevation or non-ST elevation ACS from October 2010 to October 2011. Patients who received loading doses of aspirin (300 mg) and clopidogrel (600 mg) before PCI and tirofiban (10 mg/kg bolus with subsequent infusion 0.15 mg/kg/min for 24 h) were selected for the study (n=133, 89 with intravenous and 44 - intracoronary administration of tirofiban loading dose). We assessed hospital mortality, myocardial reinfarctions (reMI), necessity of target vessel revascularization (TVR) and pronounced bleedings. There were no significant differences in mortality, reMI, and TVR between two groups. However major adverse cardiac events was significantly less in patients who received intracoronary tirofiban (6.8 vs. 21.3% in i.v. group; p=0.046). Hospital stay was significantly shorter in intracoronary compared with i.v. group (3.84+/-0.96 vs. 4.55+/-1.11 days; p=0.001). Rates of bleedings did not differ significantly between groups. Thus compared with i.v. intracoronary administration of tirofiban loading dose allows lower rate of major adverse cardiac events as well as to shorten length of hospital stay of patients with ACS.

Abstract
There are controversial data on relatively unfavorable effect of female gender on postoperative mortality of patients underwent to coronary artery bypass grafting (CABG). In order to assess risk factors and hospital outcomes after elective CABG we studied retrospectively data on patients who had undergone CABG in Sani Konuogly medical center (Gasiatep, Turkey) during the period from March 2002 to March 2010. For elimination of unfavorable effect of old age we included into analysis data from patients younger than 65 years. In accordance with study aim all patients (n=2692) were divided into two gender groups 1966 men (mean age 54,01 years) and 726 women (mean age 54.35 years). Diabetes (48.3 and 26.9%; p=0.0001), arterial hypertension (76.6 and 28.4%; p=0.00001), and obesity (50 42%; p=0.03) were more frequent among women while smoking (44.5 and 10.3%; p=0.0001), hyperlipidemia (37.6 and 21.5%; p=0.0002), and history of myocardial infarction (31.3 and 17.3%; p=0.06) were more often registered among men. Mortality was insignificantly higher in women (1.6 and 0.9%; p=0.06). Perioperative Q-wave myocardial infarction was more frequent among men than among women (1.5 and 0.4% respectively; p=0.04). It is necessary to conduct prospective well controlled study for exclusion of gender influences on perioperative outcomes in patients subjected to CABG .

Abstract
Some women have negative mood symptoms, caused by progestagens in hormonal contraceptives or sequential hormone therapy or by progesterone in the luteal phase of the menstrual cycle, which may be attributed to metabolites acting on the GABA-A receptor. The GABA system is the major inhibitory system in the adult CNS and most positive modulators of the GABA-A receptor (benzodiazepines, barbiturates, alcohol, GABA steroids), induce inhibitory (e.g. anesthetic, sedative, anticonvulsant, anxiolytic) effects. However, some individuals have adverse effects (seizures, increased pain, anxiety, irritability, aggression) upon exposure. Positive GABA-A receptor modulators induce strong paradoxical effects including negative mood in 3%-8% of those exposed, while up to 25% have moderate symptoms. The effect is biphasic: low concentrations induce an adverse anxiogenic effect while higher concentrations decrease this effect and show inhibitory, calming properties. The prevalence of premenstrual dysphoric disorder (PMDD) is also 3%-8% among women in fertile ages, and up to 25% have more moderate symptoms of premenstrual syndrome (PMS). Patients with PMDD have severe luteal phase-related symptoms and show changes in GABA-A receptor sensitivity and GABA concentrations. Findings suggest that negative mood symptoms in women with PMDD are caused by the paradoxical effect of allopregnanolone mediated via the GABA-A receptor, which may be explained by one or more of three hypotheses regarding the paradoxical effect of GABA steroids on behavior: (1) under certain conditions, such as puberty, the relative fraction of certain GABA-A receptor subtypes may be altered, and at those subtypes the GABA steroids may act as negative modulators in contrast to their usual role as positive modulators; (2) in certain brain areas of vulnerable women the transmembrane Cl(-) gradient may be altered by factors such as estrogens that favor excitability; (3) inhibition of inhibitory neurons may promote disinhibition, and hence excitability.

Abstract
We describe a family with progressive skeletal dysplasia and severe spinal involvement, short stature, premature arthrosis and joint contractures diagnosed as spondyloepiphyseal dysplasia Omani type. Mutation analysis in CHST3, the gene encoding for the chondroitin 6-O-sulfotransferase-1 (C6ST-1), revealed a homozygous missense mutation (T141M) in exon 3 in all three affected members of the family. Using recombinant C6ST-1, we showed that the identified missense mutation results in a reduction of C6ST-1 activity to 24-29% of the wild type protein. In addition to the previously noted skeletal features, affected members of this family also had cardiac involvement including mitral, tricuspid and/or aortic regurgitations and type E brachydactyly.

Abstract
BACKGROUND Ischaemia is a common phenomenon in the pathogenesis of a wide range of medical and surgical conditions, including myocardial infarction, mesenteric vascular occlusion and compartment syndrome. Ischaemia modified albumin has been suggested as an aid to clinical decision making in various clinical settings. This study examines the usefulness of IMA in the diagnosis of limb ischaemia (LI). METHODS This case-controlled study was performed in the emergency department of Karadeniz Technical University Hospital, Turkey. 22 patients presenting to the emergency departments and definitively diagnosed with LI were enrolled in the study. A control group of 22 healthy volunteers served as a reference for biochemical parameters. RESULTS The mean serum IMA level for LI patients was 0.295 (SD 0.062) ABSU. The mean serum IMA level for control patients was 0.174 (SD 0.061) ABSU. There was a statistically significant difference between the mean LI patient and mean control patient IMA levels (p<0.0005). A ROC curve analysis reveals the relationship between sensitivity and specificity for IMA in limb ischaemia. CONCLUSION There is a significant increase in serum IMA in limb ischaemia. Furthermore, using a cutoff of 0.22 ABSU, ROC curve analysis shows that IMA is 81.8% sensitive and 81.8% specific 81.8% in patients with clinically severe lower limb ischaemia. Future studies would be needed to determine if IMA would be clinically useful in the diagnosis of subtle limb ischaemia.

Abstract
A 31 year old man with prosthetic aortic valve replacement presented with sudden onset of colic right flank pain. Analysis of the urine revealed haematuria, and the international normalised ratio was suboptimal. The patient was misdiagnosed as having ureteral colic. On the second day, an ultrasound showed no signs of obstructive uropathy, and there was no evidence of absent function on intravenous pyelogram. Computed tomography with contrast agent was performed and revealed a right renal infarction. Renal angiography demonstrated total occlusion of the right renal artery. Fibrinolytic therapy and angioplasty were unsuccessful. To our knowledge, aortic prosthetic valve thrombus as a source of renal artery embolism mimicking renal colic has not been reported previously. This case underlines the importance of renal colic as a manifestation of renal infarction in patients with prosthetic valves and the need for a high index of suspicion of renal embolism.

Abstract
BACKGROUND One of the prominent features of Behçet's disease (BD) is vasculitis and thrombosis as a result of endothelial dysfunction. Nitric oxide (NO) is responsible for endothelial vasorelaxation and inhibition of platelet adhesion. OBJECTIVES To assess serum total NO, erythrocyte superoxide dismutase (SOD), whole blood glutathione peroxidase (GSH-Px), plasma total antioxidant status (TAS) and plasma malondialdehyde (MDA) in patients with BD and to correlate their levels with disease activity. METHODS The study group consisted of 49 patients with BD and 26 healthy control subjects. None of the subjects was given a standardized diet. Patients with any systemic disease were excluded. Patients with BD were randomized to two groups according to their disease activity (active/inactive, 26/23). We measured serum total NO levels using the enzyme-linked immunosorbent assay method, and SOD, GSH-Px, TAS and MDA levels by spectrophotometric methods. RESULTS In patients with active disease (n = 26), serum total NO levels were found to be significantly decreased when compared with the inactive (n = 23) and control (n = 26) groups. Levels were also significantly lower in patients with inactive disease and in total BD patients (n = 49) than in the controls. GSH-Px activities and TAS levels were significantly lower in total BD patients than those in the controls. Patients with active disease and total BD patients exhibited markedly higher MDA levels than the control subjects. MDA levels in the patients with active disease were also found to be elevated compared with the patients with inactive disease. CONCLUSIONS We conclude that changes in parameters associated with oxidative stress such as NO-related processes, activities of antioxidant enzymes in the bloodstream and erythrocytes and total plasma antioxidant capacity are involved in the aetiopathogenesis of the vasculitis seen in BD.

Abstract
We aimed to compare the effects of two different gonadotropins on steroid production in patients with polycystic ovary syndrome (PCOS). The study group comprised 20 infertile patients diagnosed with PCOS who were accepted into in vitro fertilization-embryo transfer and gamete intra-Fallopian transfer programs. Ten patients were consecutively allocated to a purified urinary follicle stimulating hormone (FSH) administration group while the other ten received human menopausal gonadotropin (hMG). All patients were pretreated with a gonadotropin releasing hormone-agonist. The patients were followed by daily vaginal ultrasonography until at least two follicles reached a diameter of 17 mm or an estradiol value of at least 100 pg/ml per follicle. To induce ovulation, human chorionic gonadotropin was given. On the 3rd day of menstruation, serum estradiol, luteinizing hormone (LH), FSH, total testosterone, androstenedione, dehydroepiandrosterone sulfate (DHEAS), insulin-like growth factor-I and insulin were measured. These same parameters were measured again on the day of follicle aspiration in both serum and follicular fluid. In both groups, the serum levels of estradiol and androstenedione were raised significantly, and on aspiration day the serum level of DHEAS was significantly raised in the FSH group but not in the hMG group. Our findings suggest that in PCOS patients exogenous hMG induces a different steroid synthesis pattern compared to pure FSH, hypothetically by reduction of the delta-5 steroid synthesis pathway in the adrenals and/or in the ovary.

Abstract
BACKGROUND The aim of this study was to evaluate the transfusional transmitted virus (TTV) seroprevalence in asymptomatic HBsAg (+) patients and to assess the influence of TTV on the course of these patients. METHODS Sixty asymptomatic HBV carriers were included and 31 healthy volunteers served as controls. Cases were followed at 6-month intervals for a total duration of 4 years. RESULTS In the asymptomatic carrier group, 31 patients (51.7%) had a history of surgery and 10 (16.7%) had a history of blood transfusions. TTV-DNA was detected in 45 of these patients (75%). In the control group, 12 patients (38.7%) had a history of surgery and 2 had (6.5%) a history of blood transfusions. TTV-DNA was found in 20 (64.5%) of these subjects. The incidence of TTV-DNA positivity was not significantly different between the two groups (P > 0.05). CONCLUSION In spite of the common occurrence of HBV and TTV, TTV-DNA was also detected in 64.5% of healthy controls. Furthermore, during 4 years of follow up, TTV had no detrimental effects on the course of asymptomatic HBV carriers. These results suggest that the hepatic injury due to TTV is insignificant in this group of patients.

Abstract
To date, BRCA1 and BRCA2 mutations in breast and/or ovarian patients have not been characterized in the Turkish population. We investigated the presence of BRCA mutations in 53 individuals with a personal and family history of breast and/or ovarian cancer, and 52 individuals with a personal history of breast cancer diagnosed below age 50 without additional family history. We have identified 11 mutations (nine BRCA1 and two BRCA2) using combined techniques involving protein truncation test, direct sequencing and heteroduplex analysis. We found eight out of 53 patients (15.1%) with a family history to carry BRCA gene mutations (seven BRCA1 and one BRCA2). Of these, four were found in 43 families presenting only breast cancer histories, and four were found in families presenting ovarian cancer with or without breast cancer. We also demonstrated two BRCA1 and one BRCA2 mutations in three out of 52 (5.8%) early-onset breast cancer cases without additional family history. Three of nine BRCA1 and both BRCA2 mutations detected in this study were not reported previously. These mutations may be specific to the Turkish population. The BRCA1 5382insC mutation, specific to Ashkenazi and Russian populations, was found twice in our study group, representing a possible founder mutation in the Turkish population.

Abstract
OBJECTIVE Oxidative stress plays an important role in the pathogenesis of asthma. Recent data suggest that clinical indices of the patients with asthma may not correlate with the underlying inflammatory process. We aimed to measure the level of malondialdehyde (MDA), which is a marker of lipid peroxidation, a free radical-mediated process, before and after a well-accepted treatment of asthma. METHODOLOGY Nine non-smoking females and five non-smoking males with mild-moderate asthma were included. Twenty-four age- and sex-matched, non-smoking healthy people (17 females and seven males, mean age 32.1 years, range 20-59) were included for control. After initial evaluation, spirometry, bronchoscopy with bronchoalveolar lavage (BAL), and blood sample were maintained. The patients were treated with twice-daily salmeterol inhaler (100 microg/d) and fluticasone propionate inhaler (500 microg/d). One month later the investigations were repeated. Serum MDA levels before treatment were compared with both the levels after treatment and levels of controls. Malondialdehyde levels of BAL were compared before and after treatment. RESULTS Serum MDA level of the patient before treatment was 6.7+/-0.8 nmol/mL, significantly higher than that of healthy controls; 3.8+/-0.4, P < 0.001. One month after the treatment, serum MDA level decreased to 5.3+/-0.7 nmol/mL (P < 0.001). However, this level is still significantly higher than healthy controls (P < 0.0001). Forced expiratory volume in 1 s level of the patients increased from 2.43+/-0.79 L to 3.50+/-1.21 L after the treatment (P < 0.001). CONCLUSION Although treatment with beta2-agonist and corticosteroid inhalers for the duration of 1 month reduced lipid peroxidation significantly, it was still at a level significantly higher than healthy controls. The treatment may need a longer duration to improve lipid peroxidation or an alternative regimen which is more effective in controlling inflammation may be warranted.
