RESUMO
OBJECTIVES: Sarcopenia has been demonstrated to be related to unfavorable clinical outcomes in patients with vascular diseases. The purpose of this study is to evaluate the relationship between sarcopenia and clinical results in patients with peripheral arterial disease who underwent endovascular therapy (EVT). METHODS: This single-center retrospective study involved patients with PAD who underwent peripheral EVT at Ankara City Hospital, between January 2018 and December 2021. Two groups of patients were created: sarcopenic and non-sarcopenic patients according to computed tomography angiography muscle measurements. Primary outcome measures were major and minor amputation and survival. Mortality, amputation, and clinical characteristics were compared between the two patient groups. Hazard ratios (HRs) for amputation were calculated for each risk factor via univariate and multivariate analyses. Secondary outcomes included length of hospital stay and post-procedural complications. RESULTS: The mean follow-up period was 29.9 ± 9 months for all patients. A total number of 100 patients (mean age 63.5 ± 9.2 years) were involved in the study cohort. A significant association was identified between mortality and sarcopenia (p < .001). The mortality rate in the group with sarcopenia was significantly higher than the other group; 65.7% (23 patients) versus (20%, 13 patients) (p < .001). The major amputation rate in the group with sarcopenia was 57.1%, the major amputation rate in the group without sarcopenia was calculated as 15.4%, revealing that the major amputation rate was detected to be significantly higher in the sarcopenia group (p < .001). Multivariate regression analyses showed that only sarcopenia (HR, 0.52; 95% CI, 0.21-1.27; p = 0.15) was independently associated with major amputation in patients with PAD after EVT. Kaplan-Meier analysis revealed a statistically significant difference between the survival curves of sarcopenia and non-sarcopenia patients (p < .001). CONCLUSIONS: Sarcopenia seems to be a possible risk factor associated with amputation in patients with PAD who undergo EVT. The results of this study imply that sarcopenia is a possible risk factor for overall survival in patients with PAD.
RESUMO
OBJECTIVES: Sarcopenia is an important metabolic disorder associated with end-stage liver disease and is an independent predictor of mortality in liver transplant candidates. We evaluated effects of pretransplant muscle mass, muscle quality, and visceral adipose tissue on mortality after liver transplant. MATERIALS AND METHODS: For 2015-2020, we included 65 liver transplant recipients whose records contained pretransplant liver computed tomography images. We calculated skeletal muscle mass index (muscle tissue area in centimeters squared divided by height in meters squared), visceral-to-subcutaneous fat ratio (visceral adiposity indicator), and intramuscular adipose tissue content ratio (muscle quality indicator). RESULTS: Median age was 55 years (IQR, 45-63 years), and 48 (73.8%) patients were men. During follow-up, 53 (81.5%) study group patients survived; mean survival time was 71.73 ± 3.81 months. The deceased patient group had a statistically higher pretransplant visceral-to-subcutaneous fat ratio than the survival group (P = .046). Survival was 100% for 1 positive indicator, 86.2% for 2 positive indicators, and 70.4% for 3 positive indicators (P = .096). Positive correlation was confirmed between pretransplant skeletal muscle mass index and age (P = .043) and pretransplant body mass index (weight in kilograms divided by height in meters squared) (P < .001). There was a moderate positive correlation between pretransplant intramuscular adipose tissue content ratio and age (R = 0.529, P ≤ .001) and a weak positive correlation with pretransplant body mass index (R = 0.361, P = .003). Furthermore, pretransplant visceral- tosubcutaneous fat ratio showed a weak positive correlation with age (R = 0.306, P = .013) and a weak negative correlation with the Model for End-Stage Liver Disease score (R = -0.301, P = .016). CONCLUSIONS: Pretransplant sarcopenia is an important indicator to predict mortality and morbidity in posttransplant follow-up. Visceral-to-subcutaneous fat ratio is an important parameter to evaluate sarcopenia in liver transplant patients.

INTRODUCTION: Doxorubicin (DOX) is an anthracycline cytotoxic chemotherapeutic drug that is commonly used in cancer treatment. A major side effect limiting the clinical use of DOX is cardiotoxicity due to oxidative injury. Nigella sativa (NS) is an annual flowering plant with antioxidant properties. Its seeds contain several bioactive constituents such as saturated and unsaturated fatty acids, thymoquinone, dithymoquinone, thymohydroquinone, and thymol. In this study, we investigated the effect of NS extract on DOX-induced cardiotoxicity. METHODS: The experimental study animals consisted of 28 male Sprague Dawley rats weighing between 300 and 400 g. Four study groups each of seven rats were defined: controls; NS extract; DOX; and DOX+NS. Control and DOX rats received standard food, while each rat in the NS and DOX+NS groups also received 100 mg/kg NS extract orally. At day 28 of follow-up, rats in the DOX groups were administered a single 10 mg/kg intraperitoneal dose of DOX, while rats in the control and NS groups received a single 10 mg/kg dose of physiological saline solution. All animals were monitored for 35 days. On day 35, the rats were decapitated and serum and cardiac tissue samples were obtained. Troponin and NT-proBNP levels were measured in blood sera, while malondialdehyde (MDA), nitric oxide, total antioxidant capacity (TAC), and total oxidative stress (TOS) levels were quantified in sera and tissue samples. Histological alterations that were assessed in cardiac tissue included myocyte disarray, small vessel disease, myocyte hypertrophy, and fibrosis. RESULTS: The DOX group had significantly higher NT-proBNP, TOS, and MDA, with greater histopathological derangement. TAC was significantly elevated in the DOX+NS group, which also exhibited significantly lower troponin, TOS, and MDA, as well as significantly higher TAC compared to the DOX group. Histopathological examination showed that the significant structural derangement observed in DOX rats was markedly and significantly reduced in DOX+NS rats. CONCLUSION: Our results suggest that NS extract may prevent DOX-induced cardiotoxicity and thus represents a promising cardioprotective agent.
RESUMO
BACKGROUND: Doxorubicin (DX) is used for the treatment of many types of cancer; however, a side effect of this agent is cardiotoxicity, which may lead to cardiomyopathy or cardiac failure. Oxidative stress is thought to play a major role in the development of cardiotoxic effects. Proanthocyanidins found in grapeseed (GS) extract may inhibit chemically induced lipid peroxidation and apoptosis caused by oxidative stress. We aimed to investigate the cardioprotective effects of GS extract against DX-induced cardiotoxicity. METHODS: A total of 28 male Sprague Dawley rats were grouped to receive: (a) standard nutrition (nâ¯= 7); (b) standard nutrition with an additional dose of 10â¯mg/kg DX (nâ¯= 7); (c) standard nutrition plus 100â¯mg/kg/day of GS (nâ¯= 7); (d) standard nutrition with 100â¯mg/kg/day of GS plus a single dose of 10â¯mg/kg DX. After 35 days the rats were decapitated and blood samples were taken for biochemical testing. Cardiac tissue samples were prepared for microscopy and histopathological evaluation. RESULTS: Rats in the DX group exhibited significant elevations in biomarkers such as troponin and NT-proBNP as well as in oxidative stress markers compared with all other groups. Histopathological examination corroborated these findings by demonstrating significant and severe structural injury in the cardiac tissue of DX rates. Moreover, rats in the DXâ¯+ GS group had significantly lower cardiac injury than rats in the DX group according to both biochemical (troponin and NT-proBNP) and histopathological analyses. Serum malondialdehyde levels (a marker of oxidative stress) in the DXâ¯+ GS rats were significantly lower than in the DX rats. CONCLUSION: Our findings suggest that GS may reduce the severity of DX-induced cardiotoxicity and thus has the potential to prevent cardiac injury in this setting.

OBJECTIVE: As aneurysm-related events and rupture is not eliminated, postoperative lifelong surveillance is mandatory after endovascular aneurysm repair (EVAR). For surveillance colored Doppler ultrasound (CDUS) is a standard method of noninvasive evaluation having the advantages of availability, cost-effectiveness, and lack of nephrotoxicity and radiation. We evaluated CDUS for primary surveillance tool after elective EVAR by comparing with computerized tomography. METHODS: Between January 2018 and March 2020, 84 consecutive post-EVAR patients were evaluated. First, CDUS was performed by two Doppler operators from the Radiology Department and then computed tomographic angiography (CTA) was performed. The operators were blind to CTA reports. A reporting protocol was organized for endoleak detection and largest aneurysm diameter. RESULTS: Among 84 patients, there were 11 detected endoleaks (13.1%) with CTA and seven of them was detected with CDUS (r = .884, p < .001). All Type I and III endoleaks were detected perfectly. There is an insufficiency in detecting low flow by CDUS. Eliminating this frailty, there was a strong correlation of aneurysm sac diameter measurement between CTA and CDUS (r = .777, p < .001). The sensitivity and specificity of CDUS was 63.6% and 100%, respectively. The accuracy was 95.2%. Positive and negative predictive values were 100% and 94.8%. Bland-Altman analysis and linear regression analysis showed no proportional bias (mean difference of 1.5 ± 2.2 mm, p = .233). CONCLUSIONS: For surveillance, CDUS promises accurate results without missing any potential complication requiring intervention as Type I or III endoleak. Lack of detecting Type II endoleaks may be negligible as sac enlargement was the key for reintervention in this situation and CDUS has a remarkably high correlation with CTA in sac diameter measurement. CDUS may be a primary surveillance tool for EVAR and CTA will be reserved in case of aneurysm sac enlargement, detection of an endoleak, inadequate CDUS, or in case of unexplained abdominal symptomatology. By this way we not only avoid ionizing radiation and nephrotoxic agents, but also achieve cost saving issue also.

OBJECTIVE: This study aimed to evaluate the penetration of moxifloxacin and doripenem into the pleural fluid (PF) using a rabbit model of empyema. METHODS: An empyema was induced using the intrapleural injection of turpentine (1 mL), followed 24 h later by instillation of 5 mL Klebsiella Pneumoniae (ATCC 33495), Fusobacterium nucleatum (ATCC 25586) and Streptokok Pneumoniae (ATCC 6305) into the pleural space. After an empyema was corroborated, Moxifloxacin (25 mg/kg-1) and Doripenem (20 mg/kg-1) were administered intraperitoneally. To determine the levels of antibiotics measured by High-Performance Liquid Chromatography in pleural and blood samples were obtained serially at 8, 24, 48 and 72nd hour. RESULTS: The penetration of both antibiotics into the PF was very good. The penetration rate of doripenem (area under the curve (AUC) for PF/blood (AUCPF/AUCblood) ratio=1.68) was better than moxifloxacin (ratio=0.78). Equalization time between the PF and blood concentration of doripenem was more quickly than moxifloxacin. Peak PF concentration of moxifloxacin was 0,81 µg/mL-1 and occurred 8 h after infusion and then gradually decreased; at the beginning of the blood and pleural fluid concentrations of doripenem were equal. While the pleura concentration was increasing, blood concentration was almost the same. Doripenem reached a peak concentration (0.54 µg/ml) 24 h post-administration. CONCLUSION: Differences were found in the penetration of the two antibiotics. Doripenem had convenient penetration PF compared to moxifloxacin. Due to the differences between human and rabbit pleural thickness, doripenem's pleural penetration should be examined in infection models in animals with equal pleura thickness and clinical trials.
RESUMO
BACKGROUND: The objective of this study was to determine the effects of strict volume control and nondipper situation on cardiovascular disease in chronic hemodialysis patients. METHODS: This study is an observational and cross-sectional study including 62 patients with normotensive chronic hemodialysis using no antihypertensive drugs. A series of measurements including ambulatory blood pressure monitoring, left ventricular mass index by echocardiography, common carotid artery intima-media thickness by ultrasound, and body fluids by bioimpedance analysis were conducted for all subjects. RESULTS: The patients were divided into two groups as dippers and nondippers according to their ambulatory blood pressure monitoring results. Average 48 h systolic, diastolic, and mean arterial blood pressure and nocturnal systolic, diastolic, and mean arterial blood pressure were significantly different between the dipper and nondipper groups (p<0.05). Before and after dialysis, extracellular fluid/intracellular fluid and extracellular fluid/dry body weight ratios were significantly higher in the nondipper group. Left ventricle mass index and interventricular septum thickness were significantly higher in the nondipper group (p<0.05). Left ventricle ejection fraction was significantly lower and common carotid artery intima-media thickness was higher in the nondipper group with a statistical significance (p<0.05). A two-predictor logistic model was fitted to the data to predict the comparability of dippers and nondippers. CONCLUSION: According to logistic regression analysis, the odds ratio for daytime diastolic blood pressure indicates that nondippers are 0.45 times more likely to have high blood pressure than dippers in daytime. But in night time, nondippers are about 2.55 times more likely to have high blood pressure comparing to dippers. An important finding of this study is that nondipping pattern is associated with cardiac hypertrophy and lower left ventricle ejection fraction in dialysis of patients with no hypertension. The results also suggest that applying strict volume control to achieve a normal blood pressure alone is not sufficient to reduce the risk of cardiovascular morbidity and mortality if the patients do not have a dipper status of nocturnal blood pressure.
RESUMO
BACKGROUND AND AIMS: The etiology and pathophysiology of coronary artery ectasia (CAE) has not been fully elucidated. A rapid rise in plasma copeptin has been observed in cardiovascular diseases, stroke, sepsis, and shock. This increase has diagnostic and prognostic value. The aim of this study was to investigate whether copeptin has a relationship with CAE. METHODS: This observational prospective study was carried out between October 2012 and March 2013 in the cardiology catheter laboratory with the inclusion of 44 subjects with a diagnosis of CAE and 44 age- and gender-matched individuals with normal coronary arteries. Blood samples obtained from the patients were stored at -70 °C until analysis and copeptin levels in sera were measured by ELISA. RESULTS: This study comprised 88 study participants, among whom 44 were patients meeting ectasia criteria [mean age: 58.0 ± 11.5 years; 59% (n = 26) male], and 44 were control subjects with angiographically normal coronary anatomy [mean age: 49.2 ± 10.1 years; 30% (n = 13) male]. Copeptin levels were similar between the groups (p > 0.05). In addition, there was no correlation between copeptin levels and CAE. CONCLUSION: In this study, it is examined that copeptin levels were not elevated in CAE patients.
RESUMO
Hydatid disease is caused by the larvae of Echinococcus granulosus. Domestic dogs and cats are the primary carriers of echinococcal organisms. In some particular regions of the world, this parasitic infection is still endemic. Despite the fact that hydatid disease is most frequently located in the liver (50%-70% of cases) and the lungs (20%-30% of cases), it can occur in any organ or tissue. However, intracardiac localization of hydatid cyst is very rare and it is found in less than 2% of the cases. Cardiac involvement can be caused by systemic or pulmonary circulation or direct spread from adjacent structures. After the cardiac hydatid cyst remained asymptomatic for many years, the cyst opens into the pericardium, causes cardiac tamponade, and mimics acute coronary syndrome, or it may get into the circulation and cause anaphylactic shock, which happens rarely. Because clinical signs and symptoms of cardiac hydatid cyst are not specific and varied, it may be difficult to diagnose this disease. It is critical to diagnose cardiac involvement early and perform prompt surgical intervention. Imaging findings of a patient who had a left ventricular wall cardiac hydatid disease are presented here.
RESUMO
BACKGROUND: The relationship between increased mean platelet volume (MPV) and atherosclerosis is well known. In the present study, MPV in patients with coronary slow flow (CSF) and in cases with normal coronary anatomy (NCA) was investigated and compared with the aim of identifying the relationship between CSF and MPV. PATIENTS AND METHODS: We studied 40 patients previously determined via coronary angiography as having NCA and 40 patients with CSF in the coronary blood stream, as identified by thrombolysis in myocardial infarction square. Thus, a total of 80 patients from the Elazig Education and Research Hospital (Elazig, Turkey) were included in the present study retrospectively and laboratory and anamnesis information was scanned into their files. The relationship between MPV and CSF was studied. RESULTS: MPV levels were observed to be significantly higher in the CSF group compared to the NCA group (10.05±1.3 and 8.6±0.6, p<0.001). In receiver operating characteristics analyses, it was determined that an MPV >9.05 measured in CSF patients at application had a predictive specificity of 77.5% and sensitivity of 77.5% for CSF (area under the curve: 0.825, 95% confidence interval [CI]: 0.726-0.924, p<0.0001). It was found that MPV level was an independent predictor of CSF (ß=-600, p<0.001, 95% CI: -0.383 to -0.176). CONCLUSION: MPV is increased in patients with CSF when compared to patients with NCA. This finding supports the fact that MPV could be a predictor of CSF.

OBJECTIVE: Increased carotid arterial stiffness (CAS) is a predictor of subclinical early atherosclerosis as well as carotid intima-media thickness (cIMT). We aimed to determine CAS and cIMT in Behçet's disease (BD). MATERIAL AND METHODS: BD (n=49) and rheumatoid arthritis (RA) (n=64) patients and healthy controls (HC) (n=40) were included in the study. cIMT was measured. CAS indices, including arterial compliance (AC), arterial distensibility (AD), Young's elastic modulus (YEM), Peterson's elastic modulus (Ep), and ß stiffness index (ßSI) were measured based on the diameter-pressure relationship. RESULTS: When compared to the HC group, the mean cIMT was significantly higher in the RA group (p=0.033), but it was not higher in the BD group. The CAS indices, including AD, AC, Ep, and ßSI were not significantly different among the study groups. Moreover, the cIMT and CAS indices were not significantly different between active (n=20) and inactive BD patients, and these indices were not correlated with the scores of disease activity. AD, AC and Ep were significantly lower in the BD patients with a positive pathergy reaction than in those with a negative reaction. CONCLUSION: These results suggest that BD does not directly lead to arterial stiffness or to an increase in cIMT.
RESUMO
INTRODUCTION: Chronic post-traumatic arteriovenous fistula (AVF) is a late complication of vascular injury and can be presented with symptoms of congestive heart failure, venous hypertension and distal ischaemia. We present an unusual case of chronic leg swelling in adult caused by post-traumatic AVF. CASE PRESENTATION: A 52 year old white-male patient complained of palpitation, pain and swollen right leg. Arterial pulses distally from the groin were present. His medical history revealed him to have sustained gunshot injury of the left thigh 5 years before. Angiography showed a large AVF between superficial femoral artery and femoral vein. The patient underwent surgical repair of AVF with ligation of AVF between superficial femoral artery under spinal anaesthesia. Completion angiography confirmed AVF exclusion. Leg swelling healed within a month. CONCLUSION: Post-traumatic fistula should be obliterated as soon as possible. Untreated fistula results in complications including renin-mediated hypertension and high-output heart failure, venous and/or arterial insufficiency.
RESUMO
OBJECTIVE: Fibromyalgia (FM) is a chronic disease characterized by widespread pain. Somatic complaints associated with the cardiovascular system, such as chest pain and palpitations, are frequently seen in FM patients. P and QT dispersions are simple and inexpensive measurements reflecting the regional heterogeneity of atrial and ventricular repolarization, respectively. QT dispersion can cause serious ventricular arrhythmias. The aim of the present study was to evaluate QT dispersion and P wave dispersion in patients with FM. MATERIAL AND METHODS: The study involved 48 FM patients who fulfilled the established criteria and 32 healthy controls (HC). A standard 12-lead electrocardiogram was performed on all participants. QT dispersion was defined as the difference between the longest and the shortest QT intervals. Similarly, the differences between the shortest and longest P waves were defined as P wave dispersion. RESULTS: The QT dispersion and corrected QT dispersion were shorter in the FM group compared with the HC group (p<0.001 for both). In terms of the P wave dispersion value, there was no significant difference between the FM and HC groups (p=0.088). CONCLUSION: Longer QT and P wave dispersions are not problems in patients with FM. Therefore, it may be concluded that fibromyalgia does not include an increased risk of atrial and/or ventricular arrhythmias.
RESUMO
PURPOSE: The purpose of this study was to evaluate results from computed tomography pulmonary angiography (CTPA) indicative of right ventricular dysfunction (RVD), and to assess the relationship of these results with cardiac biomarkers and mortality among patients with acute PE. MATERIALS AND METHODS: This retrospective study involved 118 patients with acute PE proved by CTPA. CTPA variables were analyzed and compared with cardiac biomarkers and echocardiography (ECHO) findings. RESULTS: Compared with ECHO, the sensitivity, specificity, positive predictive value, and negative predictive value of CTPA for detection of RVD were 85.7, 91.7, 93.7, and 81.5 %, respectively. ROC curve analysis for prediction of RVD resulted in areas under the curve of 0.925 for RV dimension (95 % CI 0.879-0.971, p < 0.001) and 0.913 for main pulmonary artery (MPA) diameter (95 % CI 0.863-0.963, p < 0.001). The optimum cut-off values for prediction of RVD were 37.5 mm for RV dimension and 29.1 mm for MPA diameter. These values were also statistically significantly greater for non-survivors than for survivors (p = 0.001, p < 0.001, respectively) and significantly associated with cardiac biomarkers. CONCLUSION: It was found that CTPA findings were significantly associated with the presence of RVD in ECHO, cardiac biomarkers, and mortality of patients with acute PE.

Integrin αvß3 (vitronectin receptor) plays a prominent role in angiogenesis, a key pathogenic feature of rheumatoid arthritis (RA). Moreover, integrin αV (ITGAV) subunit gene has been associated with a susceptibility to RA. The aim of the present study was to detect the potential association between ITGAV gene polymorphisms and a susceptibility to RA in a Turkish cohort. DNA samples were harvested from 160 patients with RA and 144 healthy controls (HC). Three single-nucleotide polymorphisms of ITGAV gene (rs3738919, rs3768777, and rs10174098) were genotyped using real-time PCR. Serum vitronectin levels were analyzed in 30 RA patients, 28 Behçet's disease (BD) patients, and 30 HC subjects. There was no significant difference between the RA and HC groups in terms of the genotypic and allelic distributions of rs3738919 and rs10174098 polymorphisms. However, the prevalence of rs3768777-G allele was higher in the RA group than in the HC group (OR 2.3, 95 % CI 1.6-3.2, p < 0.0001). Moreover, there was a significant association between RA and the genotypic distribution of rs3768777 (GG + AG vs. AA: OR 2.1, 95 % CI 1.3-3.4; GG vs. AG + AA: OR 4.1, 95 % CI 2.1-7.8). Serum vitronectin levels were lower in the RA and BD groups than in the HC group (p ANOVA = 0.002). The rs3738919 and rs10174098 polymorphisms of the ITGAV gene seem not to be associated with susceptibility to RA in Turkish patients. However, rs3768777 increases the risk of RA in this group. These results suggest that the ITGAV gene may be a candidate gene for the etiopathogenesis of RA.

OBJECTIVES: The purpose of this study was to determine whether admission soluble glycoprotein VI (sGP-VI) level is associated with no-reflow phenomenon (NRP) after primary percutaneous coronary intervention (P-PCI) in patients with acute ST-segment elevation myocardial infarction (STEMI). METHODS: A total of 178 consecutive patients admitted to our hospital for a first STEMI and undergoing P-PCI within 12 hours of onset of symptoms were enrolled. The patients were divided into 2 groups (NRP group and reflow group). Admission sGP-VI plasma levels were measured by enzyme-linked immunosorbent assay. RESULTS: Of the 178 patients who underwent P-PCI, 41 patients (23%) developed NRP. The patients in the reflow group had higher levels of sGP-VI compared with the patients in the NRP group (38.5 ± 21.0 vs 21.9 ± 11.9 ng/mL, P < 0.001). The sensitivity and specificity values of the sGP-VI levels were 90% and 49%, respectively (cutoff value was ≤ 25). In the multivariate logistic regression analyses, sGP-VI levels of 25 ng/mL or lower, higher peak troponin T levels and body mass index value, amount of opaque of greater than 250 mL, and lesion length of greater than 13.5 mm were independent predictors of angiographic NRP. CONCLUSIONS: Lower admission sGP-VI levels are associated with NRP in patients with STEMI undergoing P-PCI. This outcome may open new therapeutic facility in the setting of P-PCI.

OBJECTIVE: Systemic lupus erythematosus (SLE) and systemic sclerosis (SSc), chronic inflammatory diseases, demonstrate an increased incidence of cardiovascular manifestations and subclinical atherosclerotic disease. Salusin-α is a novel bioactive peptide that suppresses the formation of macrophage foam cells, and its serum level is significantly lower in patients with angiographically proven coronary artery disease. The aims of the study were to assess serum salusin-α level and its potential association with the predictors of atherosclerosis in SLE and SSc. MATERIAL AND METHODS: The study included 20 SLE and 22 SSc patients and 23 healthy controls (HC). All of the participants were female. Tumour necrosis factor-α (TNF-α), IL-6 and salusin-α levels, homeostasis model assessment for insulin resistance (HOMA-IR) index and common carotid intima-media thickness (IMT) were determined. RESULTS: Salusin-α levels were lower and the IMTs were higher in the SLE and SSc groups than in the HC group. The salusin-α level was correlated with neither the disease activity scores nor cytokine levels and IMT in the SLE and SSc groups, although it was correlated with triglyceride level in the SLE group (r=-0.564, p=0.012), and with HOMA-IR index in the HC group (r=0.485, p=0.019). CONCLUSION: The present preliminary study may support the idea that SSc leads to subclinical atherosclerosis, as in SLE. Moreover, it can be concluded that the decreased salusin-α levels in SLE and SSc may contribute to subclinical atherosclerosis. However, further studies with larger sample size are needed to demonstrate this contribution in SLE and SSc.
RESUMO
OBJECTIVE: Subarachnoid hemorrhage (SAH), which can cause mortality and severe morbidity, is a serious condition whose underlying cause must be determined. We aimed to compare 2D digital subtraction angiography (2DDSA), rotational angiography (RA) and 3D volume rendering digital subtraction angiography (3DVRDSA) for detecting aneurysms and their morphological properties in patients with subarachnoid hemorrhage. MATERIALS AND METHODS: After an initial diagnosis of SAH with computed tomography, 122 patients (52 males and 70 females with a mean age of 47.77 ± 12.81 ranging between 20 and 83 years) underwent 2DDSA imaging, RA and 3DVRDSA imaging for detection of aneurysms. The location of the aneurysm, the best working angles, the dome/neck ratios, the largest diameter of the aneurysm, the shape of the aneurysm, the presence of spasms or pseudostenoses, and the relationship to the neighboring arteries were recorded. RESULTS: 2DDSA missed 15.6% of the aneurysms that had a mean size of 2.79 ± 0.74 mm. RA was superior to 2DDSA for detecting aneurysm neck, and 3DVRDSA was superior to RA for detecting aneurysm neck. 3DVRDSA conclusively depicted the shape of the aneurysms in all patients. 3DVRDSA imaging was superior to 2DDSA and RA in the detection of the aneurysm relationship to neighboring arteries. The sensitivity and specificity of 3DVRDSA imaging for the detection of vasospasms were 100 and 84%, respectively. CONCLUSIONS: 3DVRDSA imaging is superior to 2DDSA and RA for detecting intracranial aneurysms and their morphological properties, especially those of small, ruptured aneurysms. However, 2DDSA should not be neglected in cases of vasospasm.

Urachal remnant disease is a relatively rare urological condition that presents a variety of clinical problems in adult patients. Contrast-enhanced multi-detector row computed tomography (MDCT) urography is a new diagnostic imaging technique providing comprehensive evaluation of the upper and lower urinary tract. MDCT urography performed with a combination of unenhanced, nephrographic phase, and excretory- phase imaging can demonstrate a wide spectrum of disease in these patients with a single study. We report a case of vesicourachal diverticulum containing calculus, which was diagnosed by MDCT urography.
