RESUMEN

Background: Adipose tissue is a dynamic endocrine organ, a highly active metabolic tissue, and an important source of cytokines. Inflammatory factors play an important role in visceral obesity associated with insulin resistance (IR), metabolic syndrome (MS), hypertension, non-alcoholic fatty liver disease (NAFLD), diabetes mellitus type 2 (DM2), endothelial dysfunction (ED) and atherosclerosis. Objectives: To examine corelation of siMS score, as a quantification method for metabolic syndrome (MS), with insulin resistance, glucoregulation parameters, as with other co-founding factors of MS, inflammation and thrombosis factors, microalbuminuria, uric acid, fatty liver index (FLI) and homocysteine. Methods: The study included 451 obese individuals with pre-metabolic syndrome (pre-MS) and MS (age 16-75, body mass index (BMI) > 25kg/m2) classified into two groups: I-age 10-30 (167 patients); II-age 31-75 (284 patients). International Diabetes Federation (IDF) classification was applied for diagnosing metabolic syndrome. Patients with less than three criteria indicated below were considered pre-metabolic syndrome. siMS risk score was used. Results: siMS score increased with age: I-3.03 ± 0.87, II-3.27 ± 0.90. siMS score correlated with associated factors of MS: hyperinsulinemia and IR, ALT, gama-GT, FLI, uric acid in both groups and CRP (p < 0.01) in group I. Correlations in II group: siMS score with PAI-1 (p = 0.01), microalbuminuria (p = 0.006), homocysteine ​​(p = 0.076). Conclusion: Correlation of siMS score with HOMA-IR confirmed that hyperinsulinism and insulin resistance are in the basis of MS. Correlation of siMS score with parameters of NAFLD, CRP, PAI-1, uric acid, microalbuminuria and homocysteine indicates that they are significant co-founding factors of MS. Correlation of siMS score with PAI-1, microalbuminuria, homocysteine, indicates higher risk for progression of endothelial dysfunction and atherosclerosis with age.

RESUMEN

AIM: To investigate the possible association between TNFα (-308 G/A) and IL-1ß (-511 C/T) single nucleotide polymorphisms (SNPs) and GSTT and GSTM deletion polymorphisms and risk of apical periodontitis (AP) development, and determine the association of different genotypes with the presence of herpesviral infection in AP. METHODOLOGY: The study included 120 periapical lesions and 200 control samples. Gene polymorphism analysis was performed using either polymerase chain reaction (PCR) or PCR/ restriction fragment length polymorphism (RFLP). Relative gene expression of TNF-α and IL-1ß was analysed using reverse transcriptase - real-time PCR. The presence of Epstein-Barr virus (EBV) and human cytomegalovirus (HCMV) was assessed by nested PCR. Chi-square and Fisher's exact tests and logistic regression analyses were done for polymorphisms, whilst Mann-Whitney U-test was performed for the expression analysis. The expected frequency of variants was analysed by the Hardy-Weinberg equilibrium test. RESULTS: TNF-α (-308 G/A) SNP increased AP susceptibility for heterozygous (odds ratio (OR) = 1.72, 95% confidence interval (CI) = 1.06-2.80, P = 0.027) and homozygous (OR = 8.55, 95% CI = 1.77-41.36, P < 0.001) carriers of the variant A allele. On the other hand, IL-1ß (-511 C/T) polymorphism exerted a protective effect both in heterozygotes (OR = 0.540, 95% CI = 0.332-0.880, P = 0.013) and homozygotes (OR = 0.114, 95% CI = 0.026-0.501, P < 0.001). In addition, GSTM1 and GSTT1 null genotypes separately, as well as concomitantly, were associated with an increased risk for AP development (P < 0.001). The null GSTT1 genotype increased approximately twice the risk of Epstein-Barr infection (EBV) in AP (OR = 2.17, 95% CI = 1-4.71, P = 0.048), whilst TNF-α SNP decreased it, both in heterozygotes (OR = 0.20, 95% CI = 0.08-0.48, P < 0.001) and AA homozygotes (OR = 0.07, 95% CI = 0.01-0.37, P = 0.001). CONCLUSIONS: GSTM and GSTT deletion polymorphisms, as well as TNFα (-308 G/A) SNP, are associated with increased risk, whereas IL-1ß (-511 C/T) polymorphism decreases the risk of AP development. GSTT and TNFα polymorphisms also appear to modulate the risk of EBV infection in Serbian patients with AP.

RESUMEN

AIM: To examine the potential systemic toxicity of nanostructured materials based on calcium silicate and calcium aluminate, for potential application in Dentistry. METHODOLOGY: Twenty-four Albino Wistar rats aged 2 months were used as an in vivo animal model for subcutaneous implantation of the investigated materials, placed in polyethylene tubes. Thirty days after implantation, the livers of the rats were analysed and following histological and stereological parameters were evaluated for volume density of hepatocytes and blood sinusoids, number and numerical density of hepatocytes, surface of hepatocytes and their nucleuses, nucleocytoplasmic ratio and mitotic index of hepatocytes. Stereological measurements were achieved using Cavalieri's principle, with grid P2 and unbiased analysis. Additionally, immunohistochemistry studies were performed to further analyse changes in liver tissue. Several haematological and biochemical parameters of blood of experimental animals were also analysed, as well as local tissue reactions around the implants. Statistical analysis was performed using parametric (anova and t-test) and nonparametric tests (Kruskal-Wallis and Mann-Whitney U-test) depending on data distribution. RESULTS: Implanted dental cements led to an increase in stereological and histological parameters in liver tissue compared to control rats. Although the investigated parameters mostly showed significant differences between control and experimental animals, the liver tissue of the experimental animals did not have visible signs of pathological changes. This was supported by the analysis of blood parameters which were not significantly different between control and experimental animals. Also, the subcutaneous tissues had minimal inflammatory reactions. Immunohistochemistry studies revealed that nanostructured materials induced proliferation of hepatocytes, but that the immunological response to the materials was not strong enough to induce proliferation of immunoreactive cells in liver in the observed time period. CONCLUSIONS: This study was performed as a contribution to the attestation of the biocompatibility of dental cements based on calcium silicate and calcium aluminate. Although these materials induced several changes in the liver structure, they were not clinically relevant and represent a normal and reversible response of the liver to the presence of biocompatible materials in the body. Blood and immunohistochemistry analyses and local tissue reactions further confirmed that these materials possess good biocompatible potential.

RESUMEN

AIM: To investigate whether apical periodontitis lesions infected by Epstein-Barr virus (EBV) exhibit higher levels of oxidative stress biomarkers [8-hydroxydeoxyguanosine (8-OHdG) and oxidized glutathione (GSSG)] and bone resorption regulators [receptor activator of nuclear factor (NF-κB) ligand (RANKL) and osteoprotegerin (OPG)] compared to EBV-negative periapical lesions and healthy pulp tissues. METHODOLOGY: The experimental group consisted of 30 EBV-positive and 30 EBV-negative periapical lesions collected in conjunction with apicoectomy. The pulp tissues of 20 impacted third molars were used as healthy controls. The qualitative and quantitative analysis of EBV was performed by nested and real-time polymerase chain reaction (PCR), respectively. The levels of RANKL and OPG were analysed by reverse transcriptase real-time PCR. The levels of 8-OHdG and GSSG were determined by enzyme-linked immunosorbent assay (ELISA). Mann-Whitney U-test and Spearman's correlation were used for statistical analysis. RESULTS: The levels of RANKL, OPG, 8-OHdG and GSSG were significantly higher in apical periodontitis lesions compared to healthy pulp controls (P = 0.001, P < 0.001, P < 0.001 and P < 0.05, respectively). RANKL and OPG mRNA expression was significantly higher in EBV-positive compared to EBV-negative periapical lesions (P < 0.05). There was no significant correlation between EBV copy numbers and levels of RANKL, OPG, 8OH-dG and GSSG in apical periodontitis. CONCLUSION: Levels of bone resorption regulators and oxidative stress biomarkers were increased in apical periodontitis compared to healthy pulp tissues. EBV-positive periapical lesions exhibited higher levels of RANKL and OPG compared to EBV-negative periapical lesions. EBV may contribute to progression of apical periodontitis via enhanced production of bone resorption regulators.

RESUMEN

OBJECTIVES: This study aimed to analyse Epstein-Barr virus (EBV) and human cytomegalovirus (HCMV) viral loads in symptomatic and asymptomatic apical periodontitis lesions, to determine levels of TNF-α, IL-1ß and IL-6 in these lesions and to investigate a possible correlation between herpesviral copy numbers and levels of proinflammatory cytokines. MATERIALS AND METHODS: A total of 100 samples of apical periodontitis were subjected to HCMV and EBV copy numbers analysis by nested polymerase chain reaction (PCR) and TaqMan real-time PCR. The concentrations of TNF-α, IL-1ß and IL-6 were determined by ELISA method. SPSS software was used for statistical analysis. RESULTS: There were no significant differences in the occurrence of EBV and HCMV between symptomatic and asymptomatic periapical lesions (p = .686, p = .879, respectively). Only 12 of 74 EBV (16.2%) and four of 54 HCMV (13.5%) nested PCR-positive samples showed increased viral copy numbers above the limit of 125 copies/ml. There was no significant correlation between the levels of analysed proinflammatory cytokines and herpesviral copy numbers in our sample. CONCLUSION: The observed low viral loads point to a relatively rare occurrence of active EBV and HCMV infection in our sample. Latent herpesviral infection does not enhance the production of investigated proinflammatory cytokines.

RESUMEN

There are only a few published studies related to the population-based etiology of hypopituitarism. New risks for developing hypopituitarism have been recognized in the last 10 years. Aim. To present data regarding the etiology of hypopituitarism collected in a tertiary center over the last decade. This is a cross-sectional database study. Patients and Methods. We included 512 patients (pts) with hypopituitarism, with a mean age of 45.9 ± 1.7 yrs (range: 18-82; male: 57.9%). Results. Nonfunctional pituitary adenomas were presented in 205 pts (40.5%), congenital causes in 74 pts (14.6%), while acromegaly and prolactinomas were presented in 37 (7.2%) and 36 (7.0%) patients, respectively. Craniopharyngiomas were detected in 30 pts (5.9%), and head trauma due to trauma brain injury-TBI and subarachnoid hemorrhage-SAH in 27 pts (5.4%). Survivors of hemorrhagic fever with renal syndrome (HFRS) and those with previous cranial irradiation were presented in the same frequency (18 pts, 3.5% each). Conclusion. The most common causes of hypopituitarism in our database are pituitary adenomas. Increased awareness of the other causes of pituitary dysfunction, such as congenital, head trauma, extrapituitary cranial irradiation, and infections, is the reason for a higher frequency of these etiologies of hypopituitarism in the presented database.

RESUMEN

AIM: The purpose of this study was to investigate the safety and feasibility of autologous adipose-derived regenerative cells (ADRC) in the treatment of chronic anal fissure. METHOD: A prospective pilot study was conducted in six patients with chronic anal fissures at the First Surgical Clinic, Clinical Center of Serbia and at the BelPrime Clinic, Belgrade, Serbia. All patients were candidates for surgical treatment. The average duration of symptoms was 24 months. Pain assessment was quantified using a visual analogue scale and bowel continence was assessed using the Wexner incontinence score. Both were assessed before treatment and during each postoperative outpatient visit. Liposuction was performed under local or general anaesthesia. Extraction of ADRC was achieved with a closed automated medical device. The fat and ADRC were injected subcutaneously into the edge of the fissure. The rest of the pellet was infiltrated into the internal anal sphincter. The study has been registered at ClinicalTrials.gov (NCT02628522). RESULTS: Complete healing of the anal fissure and the disappearance of symptoms was achieved in all patients. The average time to complete pain cessation was 33.7 ± 15.0 days. All fissures healed after 3 months and remained healed 12 months after the procedure. There were no complications related to the procedure. CONCLUSION: The application of ADRC may be an alternative to lateral sphincterotomy and a reliable procedure which avoids faecal incontinence.

RESUMEN

The aim of this study was to assess the early electrocardiogram (ECG) changes induced by physical training in preadolescent elite footballers. This study included 94 preadolescent highly trained male footballers (FG) competing in Serbian Football League (minimum of 7 training hours/week) and 47 age-matched healthy male controls (less than 2 training hours/week) (CG). They were screened by ECG and echocardiography at a tertiary referral cardio center. Sokolow-Lyon index was used as a voltage electrocardiographic criterion for left ventricular hypertrophy diagnosis. Characteristic ECG intervals and voltage were compared and reference range was given for preadolescent footballers. Highly significant differences between FG and CG were registered in all ECG parameters: P-wave voltage (p < 0.001), S-wave (V1 or V2 lead) voltage (p < 0.001), R-wave (V5 and V6 lead) voltage (p < 0.001), ECG sum of S V1-2 + R V5-6 (p < 0.001), T-wave voltage (p < 0.001), QRS complex duration (p < 0.001), T-wave duration (p < 0.001), QTc interval duration (p < 0.001), and R/T ratio (p < 0.001). No differences were found in PQ interval duration between these two groups (p > 0.05). During 6-year follow-up period, there was no adverse cardiac event in these footballers. None of them expressed pathological ECG changes. Benign ECG changes are presented in the early stage of athlete's heart remodeling, but they are not related to pathological ECG changes and they should be regarded as ECG pattern of LV remodeling.

RESUMEN

ABSTRACT Introduction To assess predictive value of new tumor markers, precursor of prostate specific antigen (p2PSA) and its derivates-%p2PSA and prostate health index (PHI) in detection of patients with indolent and aggressive prostate cancer (PC) in a subcohort of man whose total PSA ranged from 2 to 10ng/mL. Materials and Methods This cross-sectional study included 129 consecutive male patients aged over 50 years, with no previous history of PC and with normal digital rectal examination findings, but with serum PSA in interval between 2 and 10ng/mL. All patients underwent standard transrectal ultrasonography guided prostate biopsy for the first time. For all patients, serum PSA, free PSA (fPSA) and p2PSA were measured and PHI and %p2PSA were calculated. Results PHI and %p2PSA levels were significanlty higher in patients with PC compared to those without this malignancy. The same findings have been observed in group of patients with Gleason score ≥7 compared to those with Gleason score <7. ROC analysis reveled the highest area under the curve with these two markers. Multivariate logistic regression showed significant improvement in PC detection and its agressive form (assumed as Gleason score ≥7). Conclusions New markers, derivates of p2PSA (especially %p2PSA and PHI), represente potentially very important clinical tool for predicting presence of PC, and even more important, to discriminate patients with Gleason score <7 from those with Gleason score ≥7 with total PSA in range from 2 to 10ng/mL.

RESUMEN

OBJECTIVE: This study aimed to compare two sampling methods for nasal nitric oxide in healthy individuals and allergic rhinitis patients, and to examine the within-subject reliability of nasal nitric oxide measurement. METHODS: The study included 23 allergic rhinitis patients without concomitant asthma and 10 healthy individuals. For all participants, nitric oxide levels were measured non-invasively from the lungs through the mouth (i.e. the oral fractional exhaled nitric oxide) and the nose. Nasal nitric oxide was measured by two different methods: (1) nasal aspiration via one nostril during breath holding and (2) single-breath quiet exhalation against resistance through a tight facemask (i.e. the nasal fractional exhaled nitric oxide). RESULTS: Compared with healthy participants, allergic rhinitis patients had significantly higher average oral and nasal nitric oxide levels. All methods of nitric oxide measurement had excellent reliability. CONCLUSION: Nasal nitric oxide measurement is a useful and reliable clinical tool for diagnosing allergic rhinitis in patients without asthma in an out-patient setting.

RESUMEN

BACKGROUND: Current literature provides insufficient information on the degree of cognitive impairment during and after electroconvulsive therapy (ECT), mostly due to the fact that applied tests lacked sensitivity and flexibility. Our goal was to evaluate cognitive functioning in adult depressed patients treated with bi-temporal ECT, using tests sensitive for detection of possible acute and medium-term memory changes. METHOD: Thirty adult patients with major depressive disorder, treated with a course of bi-temporal ECT, underwent clinical and cognitive measurements three times: at baseline, immediately after a course of ECT, and 1 month later. For cognition assessment, we used learning and visual, spatial and figural memory tests from the Cambridge Neuropsychological Test Automated Battery (CANTAB). RESULTS: Bi-temporal ECT has proven to be an effective treatment. The linear mixed model, used to analyze changes in depression severity and patients' cognitive performances over time and to assess dynamic correlations between aforementioned features, did not show any significant memory impairment as a potential acute or medium-term ECT effect. However, it yielded significant improvement on visual memory and learning at the follow-up, which positively correlated with the improvement of depression. CONCLUSION: Good progress is being made in the search for ECT-related acute and medium-term cognitive side-effects by using the tests sensitive to detect memory dysfunction with parallel forms of the tasks (to counter practice effects on repeat testing). Our results on learning and memory in relation to ECT during treatment of depression did not bring forth any prolonged and significant bi-temporal ECT-related memory deficit.

RESUMEN

OBJECTIVES: The aim of this study was to investigate survivin, cyclin D1, and p21hras expression in keratocystic odontogenic tumors before and after decompression, as well as in pericoronal follicles. A potential correlation between the expression levels of these proteins was also investigated. MATERIALS AND METHODS: We analyzed eighteen keratocystic tumors treated by decompression and subsequent enucleation along with seven pericoronal follicles using immunohistochemistry. RESULTS: Keratocystic tumor samples, both before and after decompression, were positive for each of the investigated proteins. In pericoronal follicles, survivin exhibited cytoplasmic staining in contrast to nuclear staining in keratocystic tumors. Cyclin D1 expression was negative in pericoronal follicles, and p21hras expression was similar in both groups. Survivin showed significantly higher expression after decompression, while cyclin D1 and p21hras remained unchanged (P = 0.039, P = 0.255, P = 0.913, respectively). There was no correlation between these proteins neither before nor after decompression. CONCLUSIONS: Within the limits of the study, we can conclude that following decompression, keratocystic odontogenic tumors preserve distinct immunohistochemical profiles of cyclin D1 and p21hras expression, despite substantial reduction in size of the lesions. Significant increase of survivin expression after decompression might be attributed to higher level of epithelial proliferation caused by this procedure.

RESUMEN

INTRODUCTION: Unlike large population studies about cardiovascular components and how they adapt to intensive physical activity, there is less research into the causes of enlargement of the respiratory system in athletes (e.g. vital capacity, maximum flow rates and pulmonary diffusion capacity). The purpose of this research was to study and compare pulmonary function in different types of sports and compare them with controls in order to find out which sports improve lung function the most. MATERIALS AND METHOD: Pulmonary functional capacities, vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and maximum voluntary ventilation (MVV) of 493 top athletes belonging to 15 different sports disciplines and of 16 sedentary individuals were studied. Pulmonary function test was performed according to ATS/ERS guidelines. RESULTS: Basketball, water polo players and rowers had statistically higher vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1) than the healthy sedentary control individuals. Football and volleyball players had lower VC while FVC was higher in the football group compared to controls. Peak expiratory flow was lower in boxing, kayak, rugby, handball, taekwondo and tennis. The maximum voluntary ventilation (MVV) was significantly higher in water polo players and rowers. Boxers had statistically lower MVV than the controls. Players of other sports did not differ from the control group. CONCLUSION: The study suggests that specific type of training used in basketball, water polo or rowing could have potential for improving pulmonary function and rehabilitation.

RESUMEN

UNLABELLED: We examined the association of alcoholic cirrhosis in 33 patients with areal bone mineral density (BMD) and the assessed bone geometric strength of their proximal femora. Lower areal BMD, cross-sectional area and section modulus, thinner cortex, and higher buckling ratio suggest that the alcoholic liver cirrhosis is associated with lower measures of bone strength. INTRODUCTION: Hepatic bone disease is an important complication of chronic liver disease and is associated with significant morbidity through fractures resulting in pain, deformity, and immobility. In this study, we examined the association of alcoholic cirrhosis and liver insufficiency stage with areal bone mineral density (aBMD) and additionally employed hip structure analysis (HSA) as an advanced method to assess bone geometric strength of the proximal femur in men with alcoholic liver cirrhosis. METHODS: The study included 33 male patients with alcoholic liver cirrhosis and a control group of 36 healthy patients. Laboratory testing included the following biochemical markers of bone turnover: serum levels of osteocalcin and C-telopeptide of type 1 collagen. Areal BMD was measured by dual x-ray absorptiometry on the proximal femora. Structural parameters were then derived from these scans using hip structure analysis software. RESULTS: After adjusting for age, body height, and weight, we found lower cross-sectional area (p = 0.005) and section modulus (p = 0.005), thinner cortex (p = 0.012), and higher buckling ratio (p = 0.043) in the neck region among patients with cirrhosis. The findings suggest that alcoholic liver cirrhosis is associated with lower measures of bone strength. These findings were consistent with decreased osteocalcin values and increased C-telopeptide of type 1 collagen in patients with cirrhosis, indicating reduction in bone formation and increased bone resorption. CONCLUSION: Our results emphasize that HSA-derived structural indices of proximal femoral structure may be an important index of greater fragility in patients with alcoholic cirrhosis.

RESUMEN

We report the relations between comorbidities and chronic venous disease. In this cross-sectional study, information was gathered from 1679 Serbian patients. The majority (65.0%) of patients were women. Mild forms of chronic venous disease (clinical, etiologic, anatomic and pathophysiologic [CEAP] classification; C0s-C1) were more frequent in women (11.6%), while severe forms (CEAP C4-C6) were more commonly encountered in men (42.1%). The most frequent comorbidity was emphysema/chronic obstructive pulmonary disease in both groups (74.3% in males and 70.6% in females). For females, diabetes mellitus (P < .005), arterial hypertension (P < .000), and skeletal/joint diseases (P < .042) were more commonly found in the C4 to C6 category. Both males and females, with severe form of chronic venous disease, may benefit from additional screening for comorbidities. Further studies are needed to clarify the nature of association among comorbidities and chronic venous disease.

RESUMEN

Patients with systemic lupus erythematosus (SLE) have an increased risk of atherosclerosis. The aim of our study was to evaluate the importance of secondary antiphospholipid presence (SAPS) in light of carotid artery intima-media thickness (CIMT) changes in SLE patients. Our study included 120 patients with SLE (46.02 ± 13.16 years), 108 women and 12 men divided into two groups: 58 patients with SAPS and 62 SLE patients without SAPS taken as a control group. All patients underwent assessment of CIMT of right and left common carotid artery (CCA) and left and right internal carotid artery (ICA) by Doppler ultrasonography. In SAPS group, 48.3 % patients had significant changes of carotid arteries comparing to 16.1 % patients in control group (p = 0.008). Average CIMT values in left and right CCA and right ICA were significantly higher in SAPS group. No significant relationship between antiphospholipid antibody type and CIMT changes was established. Multivariate regression analysis revealed SAPS as a significant predictor of CIMT changes in SLE patients (p = 0.025). Presence of SAPS in SLE patients is associated with significant CIMT changes. Additional autoimmune burden leads to a need for a more aggressive education and prevention considering standard risk factors in this group of patients.

RESUMEN

OBJECTIVE: This study aimed to compare the prognostic impact of comorbidity grading by the Adult Comorbidity Evaluation 27 index and the Charlson Comorbidity Index on the five-year overall and disease-specific survival in patients undergoing surgery for laryngeal squamous cell carcinoma. METHODS: The impact of comorbidity and other factors on survival was examined retrospectively in a group of 177 patients with previously untreated tumour stage one to four laryngeal squamous cell carcinoma surgically treated at the Clinic of Otorhinolaryngology and Maxillofacial Surgery, Clinical Centre of Serbia, between 2000 and 2003. The Cox proportional hazard model was used to identify independent prognostic factors. RESULTS: On univariate analysis, comorbidity had an impact on prognosis regardless of which index was used. On multivariate analysis, the significant predictors of patients' five-year overall and disease-specific survival were tumour-node-metastasis stage and comorbidity as graded by the Adult Comorbidity Evaluation 27 index. CONCLUSION: The Adult Comorbidity Evaluation 27 index is a more reliable predictor of survival than the Charlson Comorbidity Index in patients with laryngeal squamous cell carcinoma.

RESUMEN

OBJECTIVE: To investigate the diagnostic value of the nuclear matrix protein 22 (NMP22) test in comparison to urine cytology for the detection of upper tract urothelial carcinoma. PATIENTS AND METHODS: Patients with transitional cell carcinoma of the upper urinary tract (n = 34) and patients with renal calculosis (n = 25) were included in this study. Voided urine samples and separated catheter urine specimens were assayed for NMP22 and cytological examination. RESULTS: The sensitivity of the NMP22 test in separated and voided urine was 73.2 and 70.5%, respectively, compared to 64.7 and 58.8% of urine cytology. The specificity of the NMP22 test in separated and voided urine was 88 and 92%, respectively, compared to 96 and 96% of urine cytology. The combination of separated and voided urine is the best method because the sensitivity is 79.41% and specificity 88%. There is a high agreement of the NMP22 test in voided and separated urine (kappa = 0.795, p < 0.01), indicating that the voided urine is adequate for diagnosis. CONCLUSIONS: The NMP22 test has higher sensitivity but lower specificity than cytology. The combination of these two tests could be a very useful diagnostic method for detection of upper urothelial tumors.

RESUMEN

OBJECTIVES: We longitudinally studied outcomes of patients with juvenile idiopathic arthritis (JIA) using the Childhood Health Assessment Questionnaire (CHAQ) for physical disability and the Juvenile Arthritis Damage Index for articular (JADI-A) and extra-articular damage (JADI-E), and we correlated them with various disease activity variables. METHODS: Eighty-seven patients with JIA were included in the prospective follow-up study with median age 14 years (4.6-18.0), disease duration 5.2 years (2.0-18.9) and follow-up of 4.0 years (2.0-5.2). Besides JADI-A and JADI-E, and the assessment of active joints count, joints with limited mobility, ESR, CHAQ and radiographic damage of joints was also done. A correlation analysis of CHAQ and JADI with various disease activity variables was performed. RESULTS: The patient's distribution of JIA subtypes were polyarticular (32), systemic onset (13), oligoarticular (31), and enthesitis related arthritis (11). After a follow-up period, 46% patients had active disease compared to 83% patients at baseline (p<0.01). The CHAQ disability index improved over baseline, while radiological damage (p<0.001) and JADI-A and JADI-E scores worsened (p<0.001). CHAQ and JADI significantly correlated with the majority of disease activity variables. CHAQ DI was significantly higher in the patients with coxitis (p<0.01) and wrist arthritis (p<0.001). The most pronounced deterioration in articular damage (JADI-A) was observed in patients with sJIA (3.69 at baseline vs. 5.69 at study endpoint). CONCLUSIONS: The improvement of functional disability (CHAQ DI) was observed over the course of the disease, whereas radiological joint damage, JADI-A and JADI-E scores worsened. Children with systemic JIA, wrist arthritis, coxitis and prolonged active disease are at higher risk of progression of severe disability.
