RESUMO

OBJECTIVES: This study aimed to assess the clinical performance outcome at 36 months of molars with molar incisor hypomineralization and carious lesions, treated with two different restorative approaches following selective caries removal. METHODS: The children aged 6 to 12 years (18 female, 13 male) included in the study had at least two carious permanent first molars diagnosed with molar incisor hypomineralization. Sixty-two molars were restored in a split-mouth design. In all subjects, selective caries removal was performed so that caries was completely removed from the cavosurface walls and only soft dentin was left above the pulp chamber. Short fiber reinforced composite (SFRC; EverX Flow™) covered by micro-hybrid composite (G-Aenial® posterior composite) and Glass Hybrid (GH; Equia Forte® HT) were used as restorative materials. The restorations were evaluated according to modified United States Public Health Service (USPHS) criteria at baseline, 6, 12, 18, 24, and 36 month follow-ups. RESULTS: During the 36-month follow-up, eight GH and four SFRC restorations failed. The clinical success of both restorations decreased statistically over time (p < 0.001 for both). When variables such as restoration type, sex, age, tooth type, and time were included in the model, the risk of failure of the restorations of the left lower first molar was statistically significantly higher than that of the left upper first molar (p < 0.002). CONCLUSION: Direct composite restorations with SFRC and GH restorations perform similar clinical success with selective caries removal in the management of permanent molars affected by molar incisor hypomineralization. CLINICAL SIGNIFICANCE: SFRC or GH restorations with similar clinical success might be preferred for the management of MIH-affected molars.

RESUMO

OBJECTIVE: Objective methods to monitor the sleep of preterm infants at the neonatal intensive care unit (NICU) are required to prevent potentially adverse neurodevelopmental outcomes. This study aimed to determine the concordance of actigraphy and amplitude-integrated electroencephalogram (aEEG) against gold standard direct observation (DO) in assessing sleep/wake states of typically developing preterm infants. METHODS: This prospective observational study was conducted in a single center level III NICU. Sleep variables were measured using Philips Respironics Mini-Mitter® Actiwatch-2 for 24 h and compared with 8-h matched data of aEEG and DO. Sensitivity-specificity analysis, Cohen's kappa, prevalence-adjusted and bias-adjusted kappa (PABAK), and Bland Altman plots were generated. RESULTS: Seventeen preterm infants were recruited. A total of 11252 epochs were studied. Sensitivity (86.4%), agreement rate (67.9%), and predictive value for wake (47.9%) for the actigraphy were highest at the automatic activity threshold whereas specificity (54.5%) and predictive value for sleep (75.5%) were highest at low threshold. The sensitivity of aEEG was 79.3% and the specificity was 54.3%. At all thresholds, the agreement was largely equivalent with low kappas (0.14-0.17) and PABAK coefficients (0.22-0.35) for actigraphy and DO. Moderate agreement was observed between aEEG and DO according to the PABAK coefficient (0.44). Mean differences in sleep parameters were not different between DO and aEEG as well as DO/aEEG and actigraphy at medium threshold (p > 0.05). CONCLUSIONS: Actigraphy at medium threshold can be used in depicting sleep in typically developing preterm infants at NICU. aEEG may be an alternative adjunctive method to actigraphy for the evaluation of sleep/wake states in the NICU setting. CLINICAL TRIAL REGISTRATION NUMBER: NCT04145362.

RESUMO

PURPOSE: This study explores the effectiveness of a comprehensive structured teaching model - the "PaFein" - for instructing postgraduate pediatric dental residents in the provision of pain-free local anesthesia to children. METHODS: Ten postgraduate pediatric dental residents and 172 children between the ages 5 and 13 participated in the study following ethical approval. The previously measured baselines guided the randomization of study and control groups. The study group (five residents) attended the PaFein course (9 hours). Based on power calculations, residents performed dental injections (8 mandibular block, 8 palatal/lingual and 14 buccal infiltrations) in randomly assigned child patients. Demographic data of residents/children, parental and self-report anxiety scores and Visual Analogue Scale (VAS) pain scores were noted to examine children's anxiety and pain during dental injections. RESULTS: Children's mean anxiety score did not differ significantly between groups; however, VAS pain reports during dental injections (a, b, c, d) were found lower in the PaFein study group than the control group (p < 0.05). VAS pain reports for (a) buccal injections were 1.08 and 1.9 (p = 0.02); (b) inferior alveolar nerve blocks were 1.58 and 3.37 (p = 0.0002); (c) palatal/lingual injections were 1.34 and 3.02 (p < 0.0001); (d) total means were 1.28 and 2.59, respectively (p = 0.0001). VAS pain reports of anxious and non-anxious children in the PaFein study group (1.63 and 1.17) were also lower than the control group (3.33 and 2.39) (p < 0.0001 and p = 0.005). CONCLUSION: The "PaFein" teaching model was found to be effective in training dental residents to reduce dental injection pain in children, including the anxious ones.

RESUMO

BACKGROUND: Within the scope of minimally invasive dentistry, the use of different biocompatible remineralization agents on incisors affected by molar-incisor hypomineralization (MIH) gains importance. OBJECTIVE: To evaluate the effect of casein phosphopeptide amorphous calcium fluoride phosphate (CPP-ACFP) and calcium glycerophosphate (CaGP) in mineral density (MD) of white/creamy and yellow/brown demarcated opacities on incisors affected by MIH by means laser fluorescence (LF). METHODS: As a cross-over, randomized trial, twenty-two children with 167 incisors affected by MIH were recruited and randomly assigned to one of the two different agents and crossed over to other agents with two weeks washout in between. Incisors were examined by using LF at all before and after three months periods. RESULTS: The results of the paired t-tests for determining the period effect between the baseline findings showed significant difference in white/creamy and yellow/brown demarcated opacities of LF values for both groups (p < 0.05). The difference between both groups according to after categorization of 20% increasing in MD in the percent of change before and after application on LF values; was not found statistically significant in white/creamy (p = 0.970) and yellow/brown (p = 0.948) opacities. CONCLUSIONS: The primary outcome was CPP-ACFP and CaGP had a positive effect in decreasing hypomineralization on MIH-affected enamel for three months period.

RESUMO

OBJECTIVE: Pectus Excavatum's (PE) surgical treatment should be patient specific. In this article, we aimed to compare parallel and cross bar variations of the Nuss method and analyze if there is any difference in results. METHODS: In this study, a total of 891 patients treated with the Nuss method between August 2005 and February 2018 were considered. These were retrieved from a prospectively recorded PE database. Of these, 276 double-bar patients were included in the study. Patients with parallel bars (225 cases) and patients with crossed bars (51 cases) were compared in terms of age, gender, symmetry, family history, additional anomalies, mean operation time, postoperative hospital stay (days) and hospital readmission rate. RESULTS: The mean age was measured at 20.7 for parallel bar patients and 20.1 for crossed bars patients. There was no statistically significant difference in terms of age, gender, and mean operation time between two groups. On the other hand, statistical significance was found between two groups when analyzing the deformities' symmetry, patients' family history and additional anomalies. The statistically significant difference of postoperative hospital stay between two groups is clinically negligible. Postoperative hospital readmission rates due to serous pleural effusion were found to be significantly increased in patients with crossed bars (p < 0.001). CONCLUSION: While pleural effusion requiring readmission was statistically more frequent in cross bars, in centers where thoracentesis can be managed, Nuss method can still be applied safely, even in cases with difficult, complex deformities. LEVEL OF EVIDENCE: III. Treatment study.

RESUMO

OBJECTIVE: We assessed the clinical survival of a high-viscosity glass ionomer (HVGI) at the 2-year follow-up to restore molar incisors severely affected by hypomineralization after selective carious tissue removal (SCR). The null hypothesis tested was that there are no differences in the overall survival times in the categories of the variables of interest. METHODS: A total of 134 fully erupted first molar incisors with hypomineralization, cavitated and with moderate-to-deep carious lesions without hypersensitivity or pain (MIH treatment need index 2a-c), were included in the study. HVGI (Equia Forte®; GC, Tokyo, Japan) restorations were applied after SCR to soft carious dentin. The follow-up lasted 2 years. The end point was defined as the absence of endodontic and restorative complications. Two-year, and 18-, 12-, and 6-month survival probabilities and standard errors were calculated using the Kaplan-Meier method. Survival probabilities according to patient gender, jaw, and lesion severity groups were compared using the log-rank test. Restorations were evaluated using the modified US Public Health Service criteria. RESULTS: HVGI restorations showed cumulative survival probabilities of 95.5% at 6 months, 94% at 12 months, 87.5% at 18 months, and 87.5% at 24 months. Survival probabilities according to patient gender, jaw, and lesion severity groups were not statistically significantly different (p > 0.05). Therefore, the null hypothesis was accepted. CONCLUSION: Following SCR, HVGI restoration provided moderate survival probabilities, suggesting that the SCR technique is effective.

RESUMO

PURPOSE: To evaluate the effect of second transurethral resection (TUR) on oncological outcomes, according to the presence or absence of detrusor muscle in the initial TUR of patients with pTa Grade 3/high grade (G3/HG) tumours, who received at least 1 year of maintenance Bacillus Calmette-Guerin (BCG) therapy. PATIENTS AND METHODS: In this retrospective study, we evaluated the effect of second TUR on oncological outcomes of 93 patients with pTa G3/HG tumours, according to the presence or absence of muscle in the initial TUR. All patients received maintenance BCG therapy according to the SWOG protocol. RESULTS: Median follow-up was 36 months. If muscle is present in the initial TUR, a second TUR significantly increased median time to first recurrence, compared to those without a second TUR (77.6 vs 36.9 mos, P = .0086). If muscle is missing in the initial TUR, a second TUR significantly decreased recurrence rate (20% vs 66.7%, P = .002), increased median time to first recurrence (78.9 vs 42.7 mos, P = .0001) and median time to progression (22 vs 7 mos, P = .05), compared to those without a second TUR. CONCLUSION: In patients with pTa G3/HG tumours, if the muscle is missing in the initial TUR, a second TUR should be performed in order to attain lower recurrence rates and longer median time to recurrence and progression. If the muscle is present in the initial TUR, a second TUR will only increase median time to first recurrence.

RESUMO

OBJECTIVES: This study aimed to determine the knowledge and approaches of the participants about oral and dental health. MATERIALS AND METHODS: This was a questionnaire-based cross-sectional survey. Participants' demographic characteristics, tooth brushing habits, selection of toothpaste, and reasons for visiting the dentist were examined in this study. Participants' knowledge levels of fluoride and their attitudes toward the most common fluoride applications among preventive treatments were also evaluated. Data entry and analyses were performed using SPSS statistical software. Descriptive and inferential statistics and chi-square test were used for analyzes. RESULTS: A total of 2,744 voluntary participants including 1,938 (70.6%) females and 806 (29.4%) males responded; 1,391 (50.7%) participants know the contents of their toothpaste; 1,680 (61.2%) participants point out that fluoride is effective in preventing dental caries. Female participants reported a statistically significant difference in their knowledge of what is fluoride when compared with male participants (p = 0.0001). The knowledge level of participants who had higher levels of education were statistically significantly different when compared with the participants who had lower education levels about fluoride and fluoride applications (p = 0.0001). CONCLUSIONS: The results of this study indicate that participants' attitudes toward oral health and dental care need to be improved.

RESUMO

AIM: To determine the awareness of cardiovascular risk factors among university students in Turkey. BACKGROUND: Cardiovascular disease (CVD) is the leading cause of death in developed countries. The use of tobacco products and unhealthy diet are prominent habits that increase the risk of CVD. METHODS: Healthy university students (n = 2450) aged between 18 and 22 years in Istanbul filled out the questionnaire about the awareness of CVD risk factors and participated in this cross-sectional study. They were asked several questions with regard to the importance of CVD risk factors. FINDINGS: The leading responses for men and women were, respectively, high cholesterol (58.3; 72.3%), stress (58.8; 71.8%), hypertension (50; 64.2%), smoking (53.1; 58.7%), obesity (46.8; 64.3%), diabetes (41.7; 52.7%), inactivity (43.3; 47.8%), and CVD in family history (31.8; 44.4%). Unhealthy diet (9.7; 15.3%), exposure to second-hand cigarette smoking (24.4; 34%), and poor socioeconomic status (22.6; 22.3%) were also considered to be important. The study also revealed that men disregard the risk factors more frequently. Another comparison between body mass index groups revealed that obese subjects gave significantly lower importance to cardiovascular risk factors. CONCLUSION: Observations indicate that awareness levels of CVD risk factors have to be improved among university students. It is emphasized that primary healthcare workers are very important in the screening of CVD risk factors in an opportunistic and systematic way and in providing consultancy on changing risky behaviors (diet, smoking, etc.). Therefore, it is of utmost importance that primary healthcare workers make interventions to reduce the risk level by determining the CVD risk.

RESUMO

BACKGROUND: Omalizumab is a third-line treatment for chronic spontaneous urticaria (CSU). However, the real-life data on the impact of omalizumab on CSU-related quality of life (QoL) remain scarce. OBJECTIVES: To investigate the impact of omalizumab on QoL and its predictors in CSU. A retrospective cohort study was done. The response to therapy was evaluated using urticaria activity score over 7 days (UAS7) and urticaria control test (UCT); the impairment in QoL was assessed using dermatology life quality index (DLQI) and chronic urticaria quality of life questionnaire (CU-Q2oL). RESULTS: Forty-two patients were included. All scores improved from baseline to first month and remained stable at the third month of treatment (p < .001). The gender, age, and angioedema had no significant effect on QoL, but the complete responders (UAS7:0-1) had better improvement rates in all scores compared to others. The baseline UAS7, DLQI, and CU-Q2oL scores were lower at the baseline in complete responders (p = .0001). CONCLUSIONS: A rapid and continual improvement in QoL was obtained with omalizumab treatment. A better UAS7, UCT, DLQI, and CU-Q2oL score at the baseline might be a predictor of a better response to omalizumab and more improvement in QoL.

RESUMO

BACKGROUND: In this study, we aimed to investigate the mid-term effects of left ventricular assist devices on kidney functions. METHODS: Between January 2015 and December 2017, a total of 61 patients (53 males, 8 females; mean age 46.4±11.2 years; range, 20 to 67 years) who underwent left ventricular assist device implantation were retrospectively analyzed. Glomerular filtration rate was evaluated preoperatively and at 24 and 48 h, at one week, and at one, three, and six months postoperatively. According to the preoperative glomerular filtration rates, the patients were divided into three groups: glomerular filtration rates ?60 mL/min/1.73 m2 ( Group 1 ), g lomerular f iltration rates 61-90 mL/min/1.73 m2 (Group 2), and glomerular filtration rates >90 mL/min/1.73 m2 (Group 3). RESULTS: In all groups, the glomerular filtration rate significantly increased at one week and one month postoperatively, compared to preoperative values (p<0.001 and p<0.01, respectively). However, the glomerular filtration values at six months significantly decreased, compared to the values at one week and one month postoperatively (p<0.001 and p<0.001, respectively). The most significant drop to preoperative values was observed in Group 3 (p=0.02) at three months and it dropped below the preoperative level at six months (p<0.001). CONCLUSION: Our study results suggest that left ventricular assist devices can significantly increase the glomerular filtration rate in short-term, irrespective of baseline values. However, this improvement may recede later, particularly in patients with normal renal functions, and it may even disappear following the third postoperative month.

RESUMO

OBJECTIVE: Macroscopic complete resection (MCR) is the recommended surgical strategy in malignant pleural mesothelioma. Our objective was to analyze whether MCR influences survival in malignant pleural mesothelioma. METHODS: Between 2002 and 2016, 154 patients underwent pleurectomy decortication (n = 90), extrapleural pneumonectomy (n = 42), or exploratory/diagnostic procedures (n = 22) in a single institution. Patient data were recorded in a prospective database. Patients who underwent surgical resection (n = 132) were analyzed according to MCR as a whole group and after propensity score matching based on gender, age, histology, clinical T and N status, adjuvant chemotherapy, and trimodality treatment. Kaplan-Meier survival and univariate and multivariate analyses were performed. RESULTS: Median age was 56 years (range, 26 to 80 years) and 62 were women. One hundred ten had epithelioid histology. MCR was achieved in 75 patients (49%). In-hospital mortality was seen in 7 patients (4.5%). Preoperative chemotherapy was applied in 32 patients. One hundred thirty-three patients underwent adjuvant treatment (45 had chemoradiation). Mean follow-up was 21 ± 19 months. Overall median survival, 2-year, and 5-year survivals were 18.1 months, 36%, and 16%, respectively. There was no difference in median survival between patients who underwent MCR (21.4 months) and who did not (16.3 months) (P = .6). Following propensity score matching (23 patients in each group), median survivals were similar (13.3 vs 14.2 months; P = .63). CONCLUSIONS: MCR was not associated with improved survival in malignant pleural mesothelioma. We need to clearly define MCR and identify subgroups of patients who would benefit from this principle because minimal versus extensive and location of gross residual disease may have different influences on survival.

RESUMO

INTRODUCTION: To evaluate the pathological outcomes of Turkish men meeting the criteria for Active Surveillance (AS), who elected to undergo immediate radical prostatectomy (RP). MATERIAL AND METHODS: Retrospective analysis including 1,212 patients with clinically localized prostate cancer (PCa) who met the eligibility criteria for AS. The primary outcomes were pathological upstaging and pathological upgrading. RESULTS: Nine hundred ninety-one patients were eligible for analysis after the central review of the submitted data. The mean prostate-specific antigen (PSA) level was 6.89 (0.51-15) ng/mL and the mean biopsy core number was 12 (8-47). The mean tumor positive core on final biopsy pathology was 1.95 (1-6) (16.6% [2.1-33.3%]). Overall, 30.6% of the men experienced a Gleason sum (GS) upgrade and 13.2% had pathological upstaging. For GS upgrade, the percentage of tumor-positive cores and free-to-total-PSA ratio were significant both in univariate analysis and multivariate logistic regression analysis. Variables predicting pathological upstaging were percentage of tumor-positive cores and PSA density, which were significant in univariate analysis. However, only PSA density was significant in multivariate logistic regression. Although biochemical recurrence-free survival was longer in patients without GS upgrade, it was not statistically significant between patients with and without any GS upgrade (mean 133.7 vs. 148.2 months, p = 0.243). A similar observation was made for patients with or without pathological upstaging (mean 117.1 vs. 148.3 months, p = 0.190). CONCLUSIONS: Upgrading and upstaging at RP are quite common among Turkish men with clinically low-risk PCa, who are candidates for AS, and a great majority of them experienced long-term PSA control.

RESUMO

OBJECTIVE The semisitting position of a patient confers numerous advantages in various neurosurgical procedures, but venous air embolism is one of the associated complications of this position. To date, no prospective studies of the relationship between the degree of head elevation and the rate and severity of venous air embolism for patients undergoing a procedure in this position have been performed. In this study, the authors compared changes in the severity of venous air embolism according to the degree of head elevation (30° or 45°) in patients undergoing an elective cranial neurosurgical procedure in the semisitting position. METHODS One hundred patients undergoing an elective infratentorial craniotomy in the semisitting position were included, and each patient was assigned to 1 of 2 groups. In Group 1, each patient's head was elevated 30° during surgery, and in Group 2, each patient's head elevation was 45°. Patients were assigned to their group according to the location of their lesion. During surgery, the standard anesthetic protocol was used with total intravenous anesthesia, and transesophageal echocardiography was used to detect air in the blood circulation. Any air embolism seen on the echocardiography screen was classified as Grade 0 to 4. If multiple events occurred, the worst graded attack was used for statistical analysis. During hemodynamic changes caused by emboli, fluid and vasopressor requirements were recorded. Surgical and anesthetic complications were recorded also. All results were compared statistically, and a p value of < 0.05 was considered statistically significant. RESULTS There was a statistically significant difference between groups for the total rates of venous air emboli detected on transesophageal echocardiography (22.0% [n = 11] in Group 1 and 62.5% [n = 30] in Group 2; p < 0.0001). The rate and severity of air embolism were significantly lower in Group 1 than in Group 2 (p < 0.001). The rates of clinically important venous air embolism (Grade 2, 3, or 4, venous air embolism with decreased end-tidal carbon dioxide levels and/or hemodynamic changes) were 8.0% (n = 4) in Group 1 and 50.0% (n = 24) in Group 2 (p < 0.0001). There was no association between the rate and severity of venous air embolism with patient demographics (p > 0.05). An association was found, however, between the rate of venous air embolism and the type of surgical pathology (p < 0.001); venous embolism occurred more frequently in patients with a meningioma. There were no major surgical or anesthetic complications related to patient position during the postoperative period. CONCLUSIONS For patients in the semisitting position, an increase in the degree of head elevation is related directly to a higher rate of venous air embolism. With a 30° head elevation and our standardized technique of positioning, the semisitting position can be used safely in neurosurgical practice.

RESUMO

BACKGROUND CONTEXT: No direct comparison between brucellar spondylodiscitis (BSD) and tuberculous spondylodiscitis (TSD) exists in the literature. PURPOSE: This study aimed to compare directly the clinical features, laboratory and radiological aspects, treatment, and outcome data of patients diagnosed as BSD and TSD. STUDY DESIGN: A retrospective, multinational, and multicenter study was used. PATIENT SAMPLE: A total of 641 (TSD, 314 and BSD, 327) spondylodiscitis patients from 35 different centers in four countries (Turkey, Egypt, Albania, and Greece) were included. OUTCOME MEASURES: The pre- and peri- or post-treatment spinal deformity and neurologic deficit parameters, and mortality were carried out. METHODS: Brucellar spondylodiscitis and TSD groups were compared for demographics, clinical, laboratory, radiological, surgical interventions, treatment, and outcome data. The Student t test and Mann-Whitney U test were used for group comparisons. Significance was analyzed as two sided and inferred at 0.05 levels. RESULTS: The median baseline laboratory parameters including white blood cell count, C-reactive protein, and erythrocyte sedimentation rate were higher in TSD than BSD (p<.0001). Prevertebral, paravertebral, epidural, and psoas abscess formations along with loss of vertebral corpus height and calcification were significantly more frequent in TSD compared with BSD (p<.01). Surgical interventions and percutaneous sampling or abscess drainage were applied more frequently in TSD (p<.0001). Spinal complications including gibbus deformity, kyphosis, and scoliosis, and the number of spinal neurologic deficits, including loss of sensation, motor weakness, and paralysis were significantly higher in the TSD group (p<.05). Mortality rate was 2.22% (7 patients) in TSD, and it was 0.61% (2 patients) in the BSD group (p=.1). CONCLUSIONS: The results of this study show that TSD is a more suppurative disease with abscess formation requiring surgical intervention and characterized with spinal complications. We propose that using a constellation of constitutional symptoms (fever, back pain, and weight loss), pulmonary involvement, high inflammatory markers, and radiological findings will help to differentiate between TSD and BSD at an early stage before microbiological results are available.

RESUMO

OBJECTIVE: To validate the original food frequency questionnaire in Turkish adult population. METHODS: The cross-sectional study was conducted in June and December 2008 and 2009, and comprised adults of either gender aged 30-70 years. All subjects were Caucasians and were native Turkish speakers. The food frequency questionnaire containing 229 most frequently consumed foods under 7 topics was used for data collection. It was completed twice and the 24-hour dietary recall four times in a year. In order to assess the validity of the questionnaire, Pearson correlation, attenuation coefficient, measures of agreement between the two methods, weighted kappa statistics and Bland-Altman plots were employed. SPSS 16 was used for statistical analysis. RESULTS: Of the 120 subjects in the study, 71(59%) were males and 49(41%) were females with an overall mean age of 50.16±9.76 years. The correlation of estimated nutrient intake between the food frequency questionnaire and 24-hour dietary recall varied between 0.200 and 0.468, energy-adjusted regression was between 0.044 and 0.611 and attenuation coefficients of regression were between 0.339 and 0.658 for the selected macro and micro nutrients. Bland-Altman plots showed an acceptable agreement between the two methods. When nutrient intake was categorised in quartiles, proportions of the same or adjacent quartiles were 98.3%, 98.4%, 98.3%, 96.7% and 95% for energy, fat, protein, carbohydrates and fibre, respectively. CONCLUSIONS: The first food frequency questionnaire developed in Turkish language was an adequate and valid tool to assess the nutritional habits of the local population.

RESUMO

BACKGROUND: High-sensitivity C-reactive protein (hs-CRP) is a biomarker of continued long-term systemic inflammation and cardiovascular (CV) risk. OBJECTIVE: To analyze the association of hs-CRP levels with CV risk factors in healthy school children. METHODS: The study sample was derived from a survey on the prevalence of CV risk factors (dyslipidemia, obesity, high blood pressure, and insulin resistance in school children. Along with anthropometry, hs-CRP levels, lipids, glucose levels, and insulin levels were measured. RESULTS: Ninety-one male (12.5 ± 3.4 years) and 77 female students (12.7 ± 3.4; P = .624) were included. Median (interquartile range) hs-CRP levels were similar among boys and girls (0.4 [1.2] vs 0.5 [0.7]; P = .928). Risk factors such as obesity (16%), high triglycerides (20%), low high-density lipoprotein cholesterol (HDL-C, 16%), and elevated blood pressure (25%) were commonly observed in study participants. Gender-stratified analysis displayed that insulin resistance (18 [19.8%] vs 3 [3.9%]; P = .002) and high triglycerides (26 [28.6%] vs 8 [10.4%]; P = .003) were more commonly observed among boys compared with girls. hs-CRP levels correlated positively with cardiometabolic risk factors such as waist circumference (boys) and total cholesterol (TC)-to-HDL-C ratio. Linear regression analysis displayed that among the covariates of age, body mass index, and glucose, TC-to-HDL-C ratio was the most significant determinant of hs-CRP levels (P = .004). CONCLUSION: Cardiometabolic risk factors such as TC-to-HDL-C ratio correlate with hs-CRP levels in children and adolescents. Long-term prospective studies are needed to confirm the association between hs-CRP and cardiometabolic risk in children.

RESUMO

The authors investigated the parameters for predicting epileptiform abnormalities in a group of children diagnosed with attention-deficit/hyperactivity disorder (ADHD). The sample consisted of 148 subjects aged between 6 and 13 (8.76 ± 1.26; 25.7% female) years. Subtypes of ADHD and comorbid psychiatric disorders were defined according to DSM-IV criteria. The Wechsler Intelligence Scale for Children-Revised was applied to all patients. Most of the subjects (89.2%) had wakefulness and sleep electroencephalography examinations lasting about one hour. The authors found out that the coexistence of speech sound disorder (odds ratio [OR] 3.90, 95% confidence interval [CI]: 1.61-9.48) and higher Digit Span test performance (OR 1.24, 95% CI: 1.06-1.44) predicted the presence of accompanying epileptiform abnormalities. The prevalence of epileptiform abnormalities was 26.4%, and they were frequently localized in the frontal (41%) and centrotemporal (28.2%) regions. Higher percentage of speech sound disorder co-occurrence (64%) in subjects with rolandic spikes suggests that epileptiform abnormalities associated with ADHD can be determined genetically at least in some cases. Pathophysiology of epileptiform abnormalities in ADHD might have complex genetic and maturational background.
