Late Correction of Traumatic Nasal Deformities: A Surgical Algorithm and Experience in 120 Patients.

BACKGROUND: Traumatic nasal deformities have a wide spectrum of presentations, which further complicates their management and preoperative planning. Although many methods and algorithms have been proposed for management of specific posttraumatic nasal deformities, such as twisted, deviated, saddle, or short nose, these algorithms usually focus on a specific deformity in isolation from the remainder of the nose. OBJECTIVES: The aim of this study is to present an algorithm for traumatic nasal deformities and to evaluate the functional and aesthetic outcomes of this new algorithm by a preoperative and postoperative quality-of-life questionnaire. METHODS: Patients with traumatic nasal deformity were operated on according to our surgical algorithm. Preoperative and postoperative Rhinoplasty Outcome Evaluation (ROE) scores, which is a rhinoplasty outcome survey, were evaluated. RESULTS: A total of 120 patients were included in the study. The mean preoperative ROE score was 3.3 ± 1.9 and mean postoperative ROE score was 20.4 ± 3.2. There was a statistically significant difference between preoperative and postoperative ROE scores (P < 0.001). There was a negative, mild to moderate, statistically significant correlation between preoperative scores and benefit (difference between postoperative and preoperative scores) (r = -0.465, P < 0.001), which means patients with lower scores had more improvement from the surgery. During the follow-up period, relapse of deviation, hypertrophic inferior turbinate, and intranasal synechia were found in 9% (n = 11), 6.6% (n = 8), and 3.3% (n = 4) of patients, respectively. CONCLUSIONS: In this study, a comprehensive surgical algorithm applicable to all traumatic nasal deformities is suggested, and the results of 120 patients with traumatic nasal deformities are presented.

The relation between monocyte to HDL ratio and no-reflow phenomenon in the patients with acute ST-segment elevation myocardial infarction.

BACKGROUND: No-reflow phenomenon is a prognostic value in ST-segment elevation myocardial infarction (STEMI). Monocyte to high density lipoprotein ratio (MHR) has recently emerged as a marker of inflammation and oxidative stress in the cardiovascular disease. PURPOSE: In this study, we aimed to investigate the relation between MHR and no-reflow phenomenon in patients with STEMI undergoing primary percutaneous coronary intervention (pPCI). MATERIAL AND METHODS: A total of 600 patients with STEMI (470 men; mean age, 62 ± 12 years) admitted within 12 hours from symptom onset were included into this study. Patients were classified into 2 groups based on postintervention Thrombolysis in Myocardial Infarction (TIMI) flow grade: no-reflow-TIMI flow grade 0, 1, or 2 (group 1); angiographic success-TIMI flow grade 3 (group 2). RESULTS: According to admission whole-blood cell count results, the patients in the no-reflow group had significantly higher monocyte count and MHR values when compared with those of the reflow patients. After multivariate backward logistic regression, MHR remained independent predictors of no reflow after pPCI. Adjusted odds ratios were calculated as 1.09 for MHR (P< .001; confidence interval [CI], 1.07-1.12). Receiver operating characteristic curve analysis suggested that the optimum MHR level cutoff point for patients with no-reflow was 22.5, with a sensitivity and specificity of 70.2% and 73.3%, respectively (area under curve, 0.768; 95% CI, 0.725-0.811). CONCLUSION: In conclusion, MHR levels are one of the independent predictors of no reflow in patients with STEMI after pPCI.

Predictive Value of Atrial Electromechanical Delay on Long-Term Cardiovascular Outcomes in Hemodialysis Patients.

BACKGROUND: Atrial electromechanical delay (AEMD) times were considered independent predictors of cardiovascular morbidity among the general population. We aimed at evaluating AEMD times and other risk factors associated with 2-year combined cardiovascular (CV) events in HD patients. MATERIAL AND METHODS: Sixty hemodialysis (HD) and 44 healthy individuals were enrolled in this prospective study. Echocardiography was performed before the mid-week dialysis session for HD patients. Data were expressed as mean ± SD. Spearman test was used to assess linear associations. Survival was examined with the Kaplan-Meier method. Multivariate Cox regression analysis was used to determine the predictors of combined CV events in this cohort. RESULTS: At the beginning of the study, left intra-atrial-AEMD times were significantly longer in HD patients compared to the left intra-atrial-AEMD times in healthy individuals. After 24 months, 41 patients were still on HD treatment and 19 (31.6%) had died. Serum triglyceride, total cholesterol and albumin were found to be higher and C-reactive protein (CRP) levels, left intra-atrial EMD time (LIAT) and interatrial EMD times were found to be lower in survived HD patients. With the cut-off median values of 3.5 g/dl for albumin, 0.87 mg/dl for CRP, 157 mg/dl for total cholesterol and 151 mg/dl for triglyceride, the Kaplan-Meier curves demonstrated significant differences in terms of all-cause mortality. We also demonstrated the Kaplan-Meier survival curves of HD patients according to tertile values of LIAT. Cox regression analysis revealed that increased CRP and higher LIAT were found to be independent predictors of combined CV events. CONCLUSIONS: Increased LIAT and inflammation were found to be closely associated with 2 years combined CV events and all-cause mortality in HD patients.

Endocan, a novel marker of endothelial dysfunction in patients with essential hypertension: comparative effects of amlodipine and valsartan.

Vascular inflammation plays an important role in the pathophysiology of hypertension and high levels of endocan may reflect ongoing vascular inflammation in hypertensive patients. In the present hypothesis-generating study, we aimed at investigating the comparative effects of amlodipine and valsartan on endocan levels in newly diagnosed hypertensive patients. The study population consisted of 37 untreated hypertensive patients who were randomized to the two treatment arms. After baseline assessment, each patient was randomly allocated to either 10 mg daily of amlodipine (n = 18, 7 males) or 160 mg daily of valsartan (n = 19, 3 males) and treated for a 3-month period. Sphygmomanometric blood pressure (BP) and serum endocan were measured before and every 2 weeks during drug treatment. There was no statistically significant difference between the two treatment arms as far as baseline socio-demographic and clinical characteristics are concerned. After a 3-month treatment period, systolic and diastolic BP values significantly reduced by antihypertensive treatment (p < 0.001). Furthermore, endocan levels were significantly decreased in both treatment arms (p < 0.05). However, amlodipine caused a greater percent decrease in circulating endocan levels compared with valsartan at the end of the treatment period. Both drugs reduced high sensitivity C-reactive protein values. However, the statistical significant difference vs baseline was achieved only in the group treated with amlodipine. No correlation was found between endocan plasma levels and BP reduction. The results of this hypothesis-generating study suggest that amlodipine and valsartan decrease endocan levels in newly diagnosed hypertensive patients. The effects, which are more evident with amlodipine, may contribute to the anti-inflammatory effects exerted by the two drugs on the vascular target.

The prevalence and causes of visual impairment in young Turkish men.

OBJECTIVE: To explore the causes and prevalence of visual impairment in young Turkish men. METHODS: The health examination data of the candidates that are saved in National Defense Ministry of Turkey was used. The data of the candidates examined between 1 January 2009 and 31 December 2011 were evaluated. The total number of the candidates was 1777500. The candidates requiring advanced examination are referred to secondary and tertiary examination hospitals. RESULTS: Fourteen thousand eight hundred sixty two(14862) out of 1777500 candidates were declared unfit for compulsory military service because of ophthalmic causes. The prevalence of ophthalmologic diseases causing unfitness for military service was found 0.746% for 2009, 0.871% for 2010 and 0.889% for 2011. These included high refractive errors which was the most frequent pathology causing unfitness (40.1%). Nonsurgical retina, vitreous and optic nerve diseases were the most frequent cause of visual impairment (0.212%). Corneal and lens pathologies were the second most frequent cause of blindness (0.101%). CONCLUSIONS: The data bank in National Defense Ministry analyzed in this study is not directly intended to explore the causes and prevalence of visual impairment in Turkey. However this study gives considerable knowledge about the causes and prevalence of visual impairment in Turkey.

Prevalence and distribution of musculoskeletal disorders causing unfitness for military service among young adult men: An epidemiologic study.

OBJECTIVES: The aim of this cross-sectional epidemiologic study was to investigate the prevalence and distribution of musculoskeletal disorders causing unfitness to Turkish Military Service. METHODS: This study has been carried out by examining the medical reports of 1.777.500 people who applied to the Turkish Armed Forces for military service between 2009-2011. Age and geographic region of individuals were compiled and organized in groups. Musculoskeletal disorders were classified mainly as fracture sequel, spine disorders, absence of phalanges, extremity amputation, aggressive or multiple benign tumors of bones and pes planus. RESULTS: Unfitness to military service caused by musculoskeletal disorders was found to be 6.53‰ in 2009, 7.10‰ in 2010 and 7.28‰ in 2011. The prevalence of musculoskeletal diseases has increased by years. The prevalence of fracture squeal by years was found to be 2.83‰ in 2009, 3.10‰ in 2010 and 3.03‰ in 2011. In this study, the most common musculoskeletal disorders were: limitation of joint mobility (0.89‰), degeneration of joint surface (0.69‰), lower and upper limb discrepancies (0.60‰), posterior fusion surgery (0.59‰) and the absence of the phalanges in hand (0.51‰). We found an increase in both the prevalence of posterior fusion surgery and the absence of the phalanges in study group. CONCLUSION: These results has given information about severe musculoskeletal disorders among young adult male in Turkey. New studies including young adult female will add important information to our knowledge about musculuskelatal problems in our community.

QT dispersion increases with low glomerular filtration rate in patients with coronary artery disease.

OBJECTIVE: We aimed to evaluate the relationship between estimated glomerular filtration rate (eGFR) and QT dispersion (QTd) in patients with coronary artery disease (CAD). METHODS: Sixty patients(mean age 62.72 ± 12.48 years) included 46 male, (mean age 60.89 ± 12.70 years)and 14 female (mean age 68.71± 9.86 years) were enrolled in this study. Patients were divided into 2 groups according to their eGFR using the 6 variable MDRD equation. Group 1 consisted of patients with estimated eGFR<60 ml/min/1.73m(2) and Group 2 consisted of patients witheGFR ≥ 60 ml/min/1.73m(2). RESULTS: Baseline patient characteristics were homogeneous in both groups except for age, gender and smoking.Also, the extent of CAD was similar in both groups (p > 0.05) QTd values were found higher in group 1 than those of group 2 (57.23 ± 40.65 ms vs. 31.23 ± 14.47 ms, p = 0.002). After adjustment for age, gender and smoking using one-way ANCOVA test, statistically significant difference in QTd still existedbetween the groups (p=0.038). CONCLUSION: QTd tends to be higher in patients with poor renal function independent of severity of angiographical CAD. QTd may be a potentially useful non-invasive test in the management of patients with poor renal function, especially those with CAD.

Longitudinal analysis of vascular function and biomarkers of metabolic bone disorders before and after renal transplantation.

BACKGROUND/AIMS: The role of chronic kidney disease-mineral bone disorder (CKD-MBD) reversibility in the amelioration of vascular function and in the reduction of the risk for cardiovascular events after renal transplantation is still unknown. METHODS: We investigated the longitudinal relationship between the main biomarkers of CKD-MBD and the evolution of vascular function [flow-mediated dilatation (FMD)] after transplantation in a series of 161 patients with kidney failure maintained on chronic dialysis (5D-CKD). RESULTS: Before transplantation, FMD in patients was markedly lower (-40%, p < 0.001) than in well-matched healthy subjects and increased by 27% after transplantation (p = 0.001). Fibroblast growth factor 23 (FGF23), 25-hydroxy-vitamin D (25OHVD) and serum phosphate (p < 0.01) were independently associated with simultaneous changes in FMD. Changes in classical risk factors and in risk factors related to CKD like the glomerular filtration rate, serum albumin, C-reactive protein and insulin resistance failed to independently explain the variability in FMD changes after transplantation. CONCLUSION: Endothelium-dependent vasodilatation improves after kidney transplantation, which is parallel to the dramatic fall in FGF23, the reduction in serum phosphorus and the increase in 25OHVD levels. If these associations are causal, a part of decline in cardiovascular risk after transplantation is related to partial resolution of CKD-MBD.

KRAS mutations are associated with specific morphologic features in colon cancer.

BACKGROUND: Mutations in the KRAS gene occur at an early stage in the development of colorectal carcinoma. Importantly, KRAS mutation predicts resistance to anti-epidermal growth factor receptor therapy in stage IV disease. GOALS: The aim of the current study is to correlate histologic features of colon cancer with the presence of KRAS mutations. STUDY: Tumor tissue from 145 colon cancer resections was tested for KRAS mutations. KRAS mutation status was correlated with demographic and histologic characteristics. Statistical analysis was performed using the Pearson χ2 test and multivariate analysis. RESULTS: KRAS mutations were present in 55/145 cases (37.9%), consistent with reported rates. KRAS mutations were significantly associated with usual adenocarcinoma morphology (multivariate P=0.014), peritumoral lymphocytic response (χ2, P=0.028; multivariate P=0.017), T3-T4 status (χ2, P=0.012; multivariate P=0.015), right-sided location (multivariate P=0.027), absence of lymphovascular invasion (multivariate P=0.008), and metastases at the time of resection (multivariate P=0.034). No association was found between KRAS mutation status and other factors. CONCLUSIONS: Specific morphologic features in colon cancer suggest a higher likelihood of the presence of KRAS mutations. These morphologic features overlap partially with those associated with DNA mismatch repair gene mutations. If confirmed, these results may suggest a paradigm for directed KRAS testing.

Comparative effects of nebivolol and metoprolol on red cell distribution width and neutrophil/lymphocyte ratio in patients with newly diagnosed essential hypertension.

High level of circulating red cell distribution width (RDW) and neutrophil/lymphocyte (N/L) ratio may reflect ongoing vascular inflammation and play an important role in pathophysiology of hypertension. We evaluate the effects of nebivolol and metoprolol on the RDW and N/L in new essential hypertensive patients. After baseline assessment, 72 patients were randomly allocated to 5 mg/d of nebivolol (n = 37, 20 men) or 100 mg/d of metoprolol (n = 35, 18 men) and treated for 6 months. Blood pressure (BP), heart rate (HR), RDW, and N/L were measured before and after treatment. BP significantly decreased with both drugs (P < 0.001). Analog reduction was observed for resting HRs (P < 0.001), but metoprolol caused greater HR fall as compared with nebivolol (P < 0.001). After 6 months of treatment, nebivolol significantly lowered not only RDW but also the total white blood cell and N/L (P < 0.001, P = 0.023, P = 0.017, respectively). No changes were observed in metoprolol group. Percent decrease in RDW was found to be significantly higher in nebivolol than in the metoprolol group (P = 0.001) and remained also after correction for confounders (P = 0.012). Nebivolol improved RDW and N/L to a greater extent than metoprolol in patients with hypertension. These favorable effects may participate, together with the BP reduction, at the favorable properties of the drug in hypertension.

Vascular inflammation and aortic stiffness relate to early left ventricular diastolic dysfunction in prehypertension.

Prehypertension is characterized by an increased cardiovascular risk and by an increased prevalence of target organ damage compared with the pure normotensive state. The present study was designed to assess in prehypertensive subjects the possible relationships between early left ventricular dysfunction, vascular inflammation and aortic stiffness. The study population consisted of 31 untreated prehypertensive subjects (age: 34 ± 6 years, mean ± SD) and 31 age-matched pure normotensive controls. Left ventricular function was assessed by echocardiography, aortic distensibility parameters were derived from aortic diameters measured by ultrasonography, and high-sensitivity C-reactive protein was assessed by latex-enhanced reagent. Prehypertensive subjects displayed a significantly lower E/A ratio and a significantly greater deceleration time and isovolumetric relaxation time compared with normotensive controls. They also displayed aortic systolic diameter, diastolic diameter and mean aortic stiffness index beta significantly increased while systo-diastolic diameter change, mean aortic distensibility and aortic strain were significantly reduced compared with controls. Values of inflammatory markers were increased. At multiple regression analysis, E/A ratio was significantly related to high-sensitivity C-reactive protein and aortic stiffness index beta, after correction for age, left ventricular mass index and mean blood pressure (ß coefficient = -0.49, overall r(2) = 0.24, p = 0.01 and ß coefficient =-0.46, overall r(2) = 0.21, p = 0.02, respectively). Thus, in prehypertension, left ventricular dysfunction is significantly related to vascular inflammation and aortic stiffness, suggesting that early cardiac and vascular alterations may have an increased inflammatory process as a common pathophysiological link.

Effect of an amniotic sheet on pregnancy outcomes.

OBJECTIVES: Our aim was to evaluate whether the presence of an amniotic sheet affects obstetric and neonatal outcomes. METHODS: All singleton pregnant women with and without a sonographic diagnosis of an amniotic sheet between the 16th and 24th weeks of pregnancy were retrospectively identified. Two women without an amniotic sheet were randomly selected from the similar stratified periods as a control group for each case. The demographic characteristics and obstetric and perinatal outcomes were compared between the groups. Multivariable logistic regression was also performed for potential confounding factors. In addition, the subsequent pregnancies of 12 women with an amniotic sheet were followed during the antenatal and postnatal periods. RESULTS: The prevalence of an amniotic sheet was 1.13%. The risk factors for an amniotic sheet were primiparity, previous normal vaginal delivery, previous dilation and curettage, and previous abortions. When the groups were compared in terms of maternal and neonatal outcomes, the rates of a nuchal cord at birth, breech birth, birth weight of less than 2500 g, preterm delivery (<37 weeks), and neonatal intensive care unit admission were higher in the amniotic sheet group than the control group. There were 2 intrauterine deaths in the amniotic sheet group. In addition, an amniotic sheet was not observed again in any of the subsequent pregnancies of the 12 cases from the amniotic sheet group, and these pregnancies eventuated uneventfully. CONCLUSIONS: An amniotic sheet is associated with an increase in poor obstetric outcomes. Therefore, close monitoring of pregnancies after diagnosis is required.

Evaluation of neonatal outcomes in elective repeat cesarean delivery at term according to weeks of gestation.

AIM: Our aim is to evaluate the association between gestational age at delivery and neonatal outcomes in elective cesarean delivery. MATERIAL AND METHODS: A total of 1784 viable singleton pregnancies that were delivered by elective caesarean section at term were included in the study. All pregnancies were categorized according to the number of completed weeks of gestation (37(+0-6) , 38(+0-6) , 39(+0-6) and ≥40(+0) weeks). In this study, the patient groups compared in terms of demographic characteristics and neonatal outcomes. RESULTS: The rates of the neonatal intensive care unit admission were 8.7%. When maternal and neonatal characteristics were statistically analyzed, the incidence of advanced maternal age and previous cesarean delivery increased as gestational age at delivery decreased; the incidence of nuchal cord and delivering a baby of ≥4000 g at birth increased as gestational age at delivery increased. As compared with deliveries at 39 weeks, cesarean delivery at 37 weeks of gestation had significantly higher risk, including that of neonatal intensive care unit admission, transient tachypnea of the newborn after delivery and O(2) support. There was one perinatal death observed in the study. CONCLUSIONS: According to the results of our study, compared to elective cesarean delivery after 37 weeks of gestation, elective cesarean delivery at 37 weeks of gestation was associated with a statistically significant increase in neonatal mortality. Therefore, elective cesarean delivery should not be performed at 37 weeks of gestation and 39 weeks of gestation appears to be the ideal timing for elective cesarean delivery.

The prevalence of disorders causing disability in young adult males in Turkey between 2009-2011.

OBJECTIVE: Disability is one of the significant problems that the public faces as regards social aspects, economics, public health and politics. Our aim was to review the prevalence of diseases causing disabilities in young adult men who are declared "unfit for military service" in Turkey after medical examination. METHODS: We reviewed the prevalence of diseases among 113,175 young adult men who were referred for medical examination between 2009 and 2011. RESULTS: Prevalence of unfitness for military service was 5.56% in 2009, 6.74% in 2010 and 6.77% in 2011. Leading causes for young adult men to be rejected from military service was intellectual disability 6.88, hearing loss 3.71, epilepsy 1.59, schizophrenia 1.54 and diabetes mellitus 1.47 per thousand people. CONCLUSION: Screening for the prevalence of disability conditions is an important data source for policies to be developed. Supporting such survey with community based studies in different populations in future shall be beneficial for improvement of policies in social and health fields.

Efficacy and tolerability of antibiotic combinations in neurobrucellosis: results of the Istanbul study.

No data on whether brucellar meningitis or meningoencephalitis can be treated with oral antibiotics or whether an intravenous extended-spectrum cephalosporin, namely, ceftriaxone, which does not accumulate in phagocytes, should be added to the regimen exist in the literature. The aim of a study conducted in Istanbul, Turkey, was to compare the efficacy and tolerability of ceftriaxone-based antibiotic treatment regimens with those of an oral treatment protocol in patients with these conditions. This retrospective study enrolled 215 adult patients in 28 health care institutions from four different countries. The first protocol (P1) comprised ceftriaxone, rifampin, and doxycycline. The second protocol (P2) consisted of trimethoprim-sulfamethoxazole, rifampin, and doxycycline. In the third protocol (P3), the patients started with P1 and transferred to P2 when ceftriaxone was stopped. The treatment period was shorter with the regimens which included ceftriaxone (4.40 ± 2.47 months in P1, 6.52 ± 4.15 months in P2, and 5.18 ± 2.27 months in P3) (P = 0.002). In seven patients, therapy was modified due to antibiotic side effects. When these cases were excluded, therapeutic failure did not differ significantly between ceftriaxone-based regimens (n = 5/166, 3.0%) and the oral therapy (n = 4/42, 9.5%) (P = 0.084). The efficacy of the ceftriaxone-based regimens was found to be better (n = 6/166 [3.6%] versus n = 6/42 [14.3%]; P = 0.017) when a composite negative outcome (CNO; relapse plus therapeutic failure) was considered. Accordingly, CNO was greatest in P2 (14.3%, n = 6/42) compared to P1 (2.6%, n = 3/117) and P3 (6.1%, n = 3/49) (P = 0.020). Seemingly, ceftriaxone-based regimens are more successful and require shorter therapy than the oral treatment protocol.

Comparison of calcium acetate and sevelamer on vascular function and fibroblast growth factor 23 in CKD patients: a randomized clinical trial.

BACKGROUND: Fibroblast growth factor 23 (FGF-23) is a marker of endothelial dysfunction and atherosclerotic complications in patients with chronic kidney disease (CKD). Because previous studies suggested that sevelamer may exert effects on FGF-23 level and endothelial function independently of its phosphate-lowering action, we tested the effect of sevelamer versus calcium acetate on vascular function and FGF-23 levels. STUDY DESIGN: Randomized prospective open-label trial. SETTING & PARTICIPANTS: Patients with stage 4 CKD with hyperphosphatemia (n = 100). INTERVENTION: An 8-week intervention with sevelamer (n = 47) and calcium acetate (n = 53). OUTCOMES: The primary study outcome was change in flow-mediated vasodilatation in the forearm. The secondary outcome was change in FGF-23 levels. RESULTS: Serum phosphate levels decreased in both treatment arms (P < 0.001), but more markedly in the sevelamer group (P < 0.001). Flow-mediated vasodilatation increased from 6.1% to 7.1% (P < 0.001) in sevelamer-treated patients, whereas it was unchanged in the calcium-acetate group (6.0% vs 6.0%). In a combined analysis, treatment-induced changes in flow-mediated vasodilatation were (P < 0.001) associated with simultaneous changes in FGF-23 levels (-27.1% [-33.2% to -8.8%] for the sevelamer group; 3.5% [-8.4% to 12.1%] for the calcium acetate group), as well as with C-reactive protein and fetuin A levels. These relationships were confirmed in multiple regression analysis adjusting for changes in serum phosphate levels and other factors. LIMITATIONS: Unblinded randomized controlled study that cannot establish mechanisms of effect. CONCLUSIONS: In hyperphosphatemic patients with stage 4 CKD, treatment with phosphate lowering induces measurable improvements in flow-mediated vasodilatation. Furthermore, independently of serum phosphate level, FGF-23 level changes induced by phosphate binders are associated with simultaneous changes in flow-mediated vasodilatation. These observations are compatible with the hypothesis that FGF-23 may contribute to vascular dysfunction in this population.

A novel screening biomarker in gastric cancer: serum Dickkopf-1.

BACKGROUND/AIMS: Despite all the knowledge about gastric cancer, there is no prognostic biomarker which could be useful for early detection. Dickkopf-1 (DKK-1), a secreted protein, is known as a negative regulator of the Wnt signaling pathway. DKK-1 is reported to be over expressed in many malignant tissues. The purpose of this study was to elucidate the normal level of serum DKK-1 (sDKK-1) levels in healthy Turkish peoples and to investigate the clinical utility of sDKK-1 levels for gastric cancer screening. METHODOLOGY: Serum DKK-1 levels were measured in 69 healthy controls and in 60 gastric adenocarcinoma patients with ELISA and sDKK-1 levels were compared with clinicopathological features and outcomes in gastric cancer patients. RESULTS: Serum concentrations of DKK-1 in gastric adeno cancer patients were significantly higher than control patients (p<0.001). The optimal cut-off for sDKK-1 levels order to discriminate control group from gastric cancer patients was 25U/mL with sensitivity equal to 100% and specificity equal to 100%. CONCLUSIONS: Serum DKK-1 levels may be a potentially useful novel serologic marker for gastric cancers.

Effectiveness of local cold application on skin burns and pain after transthoracic cardioversion.

BACKGROUND: Transthoracic cardioversion (TTC) is widely used in emergency departments and daily clinical practice. TTC may cause skin lesions on the application of apical and sternal paddle areas. The lesions are characterised by redness, erythema and blister(s), and can be defined as first degree burns locally causing pain and increased sensitivity. AIM: To evaluate the effectiveness of local cold application on reducing the incidence, severity and pain/sensitivity of skin burns in patients who underwent TTC. METHODS: The study was conducted in the intensive care unit of the cardiovascular surgery department. The patients were assigned to study (n=24) and control groups (n=24). Local cold application was performed for a 1 hour period on patients in the study group, whereas only clinical procedures were applied in the control group following TTC. Incidence and severity of burn was evaluated 2 h after TTC, and pain/sensitivity scores were evaluated at 2, 4 and 24 h after TTC. Results The incidence of burn was significantly lower in the study group (3/24) compared to the control group (21/24) (12.5% vs 83.3%, p<0.001). Pain/sensitivity scores were significantly lower in the study group compared to the control group (p<0.05). CONCLUSION: Local cold application following TTC is an effective means of reducing the incidence and severity of burns and pain/sensitivity. It is cost-effective and can easily be applied by nurses in medical/surgical units and emergency departments.

Low triiodothyronine alters flow-mediated vasodilatation in advanced nondiabetic kidney disease.

BACKGROUND/AIMS: Subclinical or frank hypothyroidism is causally implicated in endothelial dysfunction. Since the plasma concentration of the active form of thyroid hormone, triiodothyronine (T3), is reduced in chronic kidney disease (CKD), where endothelial function is frequently altered, low T3 may be a factor implicated in this disturbance in CKD patients. METHODS: We investigated the relationship between flow-mediated vasodilatation (FMD) and thyroid hormones in a series of 217 nondiabetic patients with stage 3-4 CKD. RESULTS: The plasma concentration of free T3 (fT3) was closely associated with FMD (r = 0.38; p < 0.001). fT3 was also inversely associated with hemoglobin (r = -0.41; p < 0.001), systolic pressure (r = -0.28; p < 0.001) and the plasma concentration of the endogenous inhibitor of NO synthase, asymmetric dimethylarginine (ADMA; r = -0.18; p = 0.007). However, adjustment for ADMA markedly attenuated the fT3-FMD link, a phenomenon suggesting that raised plasma ADMA, possibly driven by low fT3, at least in part mediates the adverse effects of low T3 on endothelial function in CKD. CONCLUSIONS: Low T3 in patients with moderate-to-severe CKD is a marker of endothelial dysfunction. This study sets a solid rationale for designing specific intervention studies aimed at clarifying the nature (causal or not causal) of the endothelial function-T3 link in CKD.

Vascular health, systemic inflammation and progressive reduction in kidney function; clinical determinants and impact on cardiovascular outcomes.

INTRODUCTION: Systemic inflammation, endothelial dysfunction and arterial thickening contribute to the elevated cardiovascular risk of dialysis patients. However, the course of these derangements and their relative contribution to the cardiovascular risk of nondialysed chronic kidney disease (CKD) are scarcely investigated. METHODS: Flow-mediated dilatation (FMD) and intima-media thickness (IMT) were assessed in 304 nondialysed CKD patients Stages 1-5 (mean age 46 ± 12 years, 158 men), together with routine biochemical measurements, C-reactive protein (CRP) and insulin resistance. Patients were then followed for time-to-event analysis of cardiovascular outcomes (fatal and nonfatal). RESULTS: CRP and IMT increased, while FMD decreased in parallel with estimated glomerular filtration rate (eGFR) decline (P < 0.001 for all). CRP and intact parathormone, as well as eGFR, appeared as strong determinants of FMD and IMT in multivariate analyses. After a median follow-up of 41 (range 6-46) months, 30 fatal and 59 nonfatal cardiovascular events occurred. In univariate analysis, FMD, IMT and CRP were significant predictors of outcome. In a multivariate Cox model excluding IMT, both FMD [hazard ratios 0.52 (95% confidence intervals 0.37-0.73) per %] and CRP [1.07 (1.03-1.11) per mg/L] predicted cardiovascular outcomes independently of confounders. In a model excluding FMD, only CRP (and not IMT) was a significant predictor. CONCLUSIONS: Endothelial dysfunction, arterial thickening and inflammation occur in parallel with the decline in eGFR, contributing to the increased cardiovascular risk of nondialysed CKD. Our results support the use of FMD over IMT measurements to monitor nondialysed CKD patients at risk.
