OBJECTIVE: In bipolar disorder, dysregulation of mood may result from white matter abnormalities that change fiber tract length and fiber density. There are few studies evaluating the white matter microstructural changes in bipolar I patients (BD) with depressive episodes. The present study aimed to evaluate anterior corona radiata in BD patients with depressive episode using Diffusion Tensor Imaging (DTI). METHODS: Twenty-one patients with bipolar depression and 19 healthy controls were investigated and groups were matched for age and gender. Diffusion-weighted echoplanar brain images (DW-EPI) were obtained using a 1.5 T MRI scanner. Regions of interest (ROIs) were manually placed on directional maps based on principal anisotropy. Apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values of white matter were measured in the anterior corona radiata (ACR) bilaterally by diffusion tensor imaging. RESULTS: There was not a significant difference between groups of age and gender (p>0.05). Significantly lower FA was observed in bilateral ACR in bipolar patients with depression compared with healthy individuals. And there is significantly higher ADC values in the left frontal corona radiate in bipolar patients. CONCLUSION: White matter abnormalities can be detected in patients with BD using DTI. The neuropathology of these abnormalities is unclear, but neuronal and axonal loss, myelin abnormalities and reduced white matter fiber density are likely to be relevant.

BACKGROUND AND OBJECTIVES: Systemic inflammation has an important role in the initiation of atherosclerosis, which is associated with arterial stiffness (AS). Aortic flow propagation velocity (APV) is a new echocardiographic parameter of aortic stiffness. The relationship between systemic inflammation and AS has not yet been described in patients with familial Mediterranean fever (FMF). We aimed to investigate the early markers of AS in patients with FMF by measuring APV and carotid intima-media thickness (CIMT). SUBJECTS AND METHODS: Sixty-one FMF patients (43 women; mean age 27.3±6.7 years) in an attack-free period and 57 healthy individuals (36 women; mean age 28.8±7.1 years) were included in this study. The individuals with atherosclerotic risk factors were excluded from the study. The flow propagation velocity of the descending aorta and CIMT were measured to assess AS. RESULTS: APV was significantly lower (60.2±16.5 vs. 89.5±11.6 cm/sec, p<0.001) and CIMT was significantly higher (0.49±0.09 vs. 0.40±0.10 mm, p<0.001) in the FMF group compared to the control group. There were significant correlations between APV and mean CIMT (r=-0.424, p<0.001), erythrocyte sedimentation rate (ESR) (r=-0.198, p=0.032), and left ventricle ejection fraction (r=0.201, p=0.029). APV and the ESR were independent predictors of FMF in logistic regression analysis (OR=-0.900, 95% CI=0.865-0.936, p<0.001 and OR=-1.078, 95% CI=1.024-1.135, p=0.004, respectively). Mean CIMT and LVEF were independent factors associated with APV in linear regression analysis (β=-0.423, p<0.001 and β=0.199, p=0.017, respectively). CONCLUSION: We demonstrated that APV was lower in FMF patients and is related to CIMT. According to our results, APV may be an independent predictor of FMF.

PURPOSE: To evaluate the relationship between levels of total testosterone and total prostate-specific antigen (PSA) in healthy men with PSA<4 ng/mL. MATERIALS AND METHODS: The study comprised 179 men with a mean age of 59.19+/-12 years who visited Osmaniye State Hospital, Osmaniye, Turkey, between January 2006 and January 2007 for a routine checkup. The patients were divided into two subgroups: patients with PSA<2.5 mg/ml (group I, n=160 patients) and patients with PSA of 2.5 to 4 ng/mL (group II, n=19 patients). The relationship between PSA and testosterone levels was investigated in both groups and in patients aged <60 years. The mean testosterone level was calculated for patients aged <50 years and was compared with the mean value of patients aged > or =50 years. RESULTS: In all patients, the mean values for serum PSA and total testosterone were 1.27+/-0.88 ng/mL and 404.04+/-158.86 ng/mL, respectively. No correlation was detected between serum PSA and testosterone levels in either subgroup (group I, r=0.072, p=0.363; group II, r=0.031, p=0.900) or in patients aged <60 years (r=0.032, p=0.72). The mean values of testosterone in patients aged > or =50 years and in patients aged <50 years were 417.01+/-163.35 and 344.16+/-120.21 ng/dL, respectively (p=0.02). CONCLUSIONS: No impact of testosterone was found on the PSA level in healthy men with PSA <4 ng/mL. Therefore, a high serum testosterone level may not mandate adjustment of PSA values. This serum sex hormone showed a significant increment after the age of 50 years. Further studies including a larger number of patients should be carried out to confirm these findings.

Calcinosis cutis is a condition characterized by the deposition of calcium salts in the skin and subcutaneous tissues, and patients suffering from it encounter various connective tissue disorders, such as dermatomyositis (DM), scleroderma, and systemic lupus erythematosus. Although calcinosis cutis is frequently accompanied by juvenile dermatomyositis, rare cases have been reported in adult patients with DM. On the other hand, lichen sclerosus (LS) is a chronic inflammatory disease of the skin and mucosal surfaces. In the present report, we present a rare case of a 71-year-old patient with DM accompanied by ulcerated calcinosis cutis and vulvar LS.

BACKGROUND AND OBJECTIVES: Functional capacity varies significantly among patients with heart failure with reduced ejection fraction (HFrEF), and it remains unclear why functional capacity is severely compromised in some patients with HFrEF while it is preserved in others. In this study, we aimed to evaluate the role of pulmonary artery stiffness (PAS) in the functional status of patients with HFrEF. METHODS: A total of 46 heart failure (HF) patients without overt pulmonary hypertension or right HF and 52 controls were enrolled in the study. PAS was assessed on parasternal short-axis view using pulsed-wave Doppler recording of pulmonary flow one centimeter distal to the pulmonic valve annulus at a speed of 100 mm/sec. PAS was calculated according to the following formula: the ratio of maximum flow velocity shift of pulmonary flow to pulmonary acceleration time. RESULTS: PAS was significantly increased in the HFrEF group compared to the control group (10.53±2.40 vs. 7.41±1.32, p < 0.001). In sub-group analysis of patients with HFrEF, PAS was significantly associated with the functional class of the patients. HFrEF patients with poor New York Heart Association (NYHA) functional capacity had higher PAS compared those with good functional capacity. In multivariate regression analysis, NYHA class was independently correlated with PAS. CONCLUSION: PAS is associated with functional status and should be taken into consideration as an underlying pathophysiological mechanism of dyspnea in patients with HFrEF.

OBJECTIVE: The purpose of this study was to investigate the prognostic value of lymph node ratio (LNR) in patients with stage III ovarian high-grade serous carcinoma (HGSC). METHODS: A multicenter, retrospective department database review was performed to identify patients with ovarian HGSC at 6 gynecologic oncology centers in Turkey. A total of 229 node-positive women with stage III ovarian HGSC who had undergone maximal or optimal cytoreductive surgery plus systematic lymphadenectomy followed by paclitaxel plus carboplatin combination chemotherapy were included. LNR, defined as the percentage of positive lymph nodes (LNs) to total nodes recovered, was stratified into 3 groups: LNR1 (<10%), LNR2 (10%≤LNR<50%), and LNR3 (≥50%). Kaplan-Meier method was used to generate survival data. Factors predictive of outcome were analyzed using Cox proportional hazards models. RESULTS: Thirty-one women (13.6%) were classified as stage IIIA1, 15 (6.6%) as stage IIIB, and 183 (79.9%) as stage IIIC. The median age at diagnosis was 56 (range, 18–87), and the median duration of follow-up was 36 months (range, 1–120 months). For the entire cohort, the 5-year overall survival (OS) was 52.8%. An increased LNR was associated with a decrease in 5-year OS from 65.1% for LNR1, 42.5% for LNR2, and 25.6% for LNR3, respectively (p<0.001). In multivariate analysis, women with LNR≥0.50 were 2.7 times more likely to die of their tumors (hazard ratio [HR]=2.7; 95% confidence interval [CI]=1.42–5.18; p<0.001). CONCLUSION: LNR seems to be an independent prognostic factor for decreased OS in stage III ovarian HGSC patients.

OBJECTIVE: To determine factors influencing overall survival following recurrence (OSFR) in women with low-risk endometrial cancer (EC) treated with surgery alone. METHODS: A multicenter, retrospective department database review was performed to identify patients with recurrent “low-risk EC” (patients having less than 50% myometrial invasion [MMI] with grade 1 or 2 endometrioid EC) at 10 gynecologic oncology centers in Turkey. Demographic, clinicopathological, and survival data were collected. RESULTS: We identified 67 patients who developed recurrence of their EC after initially being diagnosed and treated for low-risk EC. For the entire study cohort, the median time to recurrence (TTR) was 23 months (95% confidence interval [CI]=11.5–34.5; standard error [SE]=5.8) and the median OSFR was 59 months (95% CI=12.7–105.2; SE=23.5). We observed 32 (47.8%) isolated vaginal recurrences, 6 (9%) nodal failures, 19 (28.4%) peritoneal failures, and 10 (14.9%) hematogenous disseminations. Overall, 45 relapses (67.2%) were loco-regional whereas 22 (32.8%) were extrapelvic. According to the Gynecologic Oncology Group (GOG) Trial-99, 7 (10.4%) out of 67 women with recurrent low-risk EC were qualified as high-intermediate risk (HIR). The 5-year OSFR rate was significantly higher for patients with TTR ≥36 months compared to those with TTR <36 months (74.3% compared to 33%, p=0.001). On multivariate analysis for OSFR, TTR <36 months (hazard ratio [HR]=8.46; 95% CI=1.65–43.36; p=0.010) and presence of HIR criteria (HR=4.62; 95% CI=1.69–12.58; p=0.003) were significant predictors. CONCLUSION: Low-risk EC patients recurring earlier than 36 months and those carrying HIR criteria seem more likely to succumb to their tumors after recurrence.
