The effect of high-intensity plyometric training on anaerobic performance parameters: a pilot study in U17 elite A league.

The aim of this study was to examine the effects of high-intensity plyometric training (HIPT) on some parameters in elite soccer players in the U17. Volunteer soccer players were randomly divided into two groups according to their positions: the regular training (RT) group (age: 16.71 ± 0.47 years; stature: 163.46 ± 3.31 cm; body weight: 61.04 ± 1.59 kg) and the HIPT group (age: 16.64 ± 0.50 years; stature: 165.60 ± 3.03 cm; body weight: 59.76 ± 1.92 kg), and each group included five defenders, five midfielders, and four attackers. While the RT group did only routine soccer training, the HIPT group performed high-intensity plyometric training three days a week in addition to routine soccer training. In the study, body weight, stature, sprint (10 m, 30 m, and 40 m), jump (standing long jump, right and left-limb triple hop) and 5-0-5 change of direction speed test measurements of the soccer players were taken. Skewness and Kurtosis values obtained from the pre-test and post-test measurements were calculated to test whether the normality assumption of the study was met. A mixed measure two-way ANOVA test was used to determine the difference between the pre-test and post-test. The significance was set as p < 0.05. The results indicated that 8-week high- intensity plyometric training provided more improvement in measured performance parameters than routine soccer training. As a result, when the data obtained is examined, it can be said that HIPT had better values in sprint, jump, and change of direction parameters, so plyometric training was more beneficial for anaerobic parameters than routine soccer training in children. It is recommended that the trainers make their plans considering these results.

Is YouTube useful as a source of information for approaches to reducing blood pressure and hypertension treatment?

Hypertension is an important public health problem due to its high prevalence and common complications. The aim of this study was to evaluate the quality of videos on YouTube related to reducing blood pressure and hypertension treatment. Using the six search terms "hypertension treatment", "cure hypertension", "hypertension medication", "control high blood pressure", "lower high blood pressure", and "reduce high blood pressure", a total of 360 relevant videos on YouTube were evaluated. Some parameters, i.e., the length of the video, number of days on YouTube, number of view counts, and number of likes, dislikes, and comments, were noted for all videos. The Global Quality Scale (GQS) was used to evaluate the quality of the videos. We categorized the video content as useful or misleading using the evidence-based medical literature. After exclusions, 104 videos were evaluated by two independent reviewers. Out of all the videos, 51% were useful, and 49% were misleading. Videos mentioned lifestyle changes (LCs) more (65 videos, 62.5%), and only 39.4% (41 videos) of all the videos contained information about pharmacological treatment (PT). Videos about alternative treatment (AT) had high numbers of views, and videos about PT had low numbers of views, and this difference was statistically significant. Videos that did not include PT but did include LCs and AT had more likes, similar to the number of views.

Tetraphenylethylene-thiosemicarbazone based ultrafast, highly sensitive detection of hypochlorite in aqueous environments and dairy products.

We have designed and synthesised a novel fluorescent probe with a tetraphenylethylene (TPE) scaffold as an active fluorescent unit and thiosemicarbazide (TSC) group as a recognition unit. The probe, TPE-TSC, exhibited superior selectivity towards hypochlorite (ClO-) with a low limit of detection (2.0 nM). It also demonstrated a turn-off response for a brief period (<30 s) via an oxidation reaction. Furthermore, high-resolution mass spectrometry (HRMS) revealed that TPE-TSC reacted with ClO- by forming a carboxylic acid moiety in nearly 100% aqueous environments. More significantly, the probe detected ClO- in disinfectant, spiked milk samples, and spiked water samples. In all, TPE-TSC proposes an optimistic approach precisely for the determining the quality of milk and water contaminated with ClO- and trace amounts of ClO- in disinfectants.

Rapid, ultrasensitive, highly selective detection of toxic Hg(II) ions in seabass, swordfish and water samples.

A novel fluorescent probe bearing triphenylamine, thiophene and thiosemicarbazide (TPA-TSC) was developed, and its distinct features were investigated. TPA-TSC demonstrated excellent selectivity towards Hg2+ ions, with a limit of detection (0.14 nM) among the lowest reported to date. It also exhibited a turn-off response by forming stable complex for a brief period (<30 s). Job plot analysis and high-resolution mass spectrometry (HRMS) revealed that TPA-TSC bound to Hg2+ with a 2:1 stoichiometry in an aqueous environment, remarkably the probe successfully detected Hg2+ ions in seabass, swordfish and different samples of water. In all, TPA-TSC offers a promising method for accurately determining the quality of seafood and water samples polluted with Hg2+.

Serum vaspin levels and carotid intima-media thickness in predialysis patients.

BACKGROUND AND OBJECTIVE: Visceral adipose tissue-derived serine proteinase inhibitor (vaspin) is an adipokine that correlates with insulin resistance and obesity in human beings. Previous studies have evaluated the serum vaspin levels in several diseases such as chronic haemodialysis patients and coronary artery disease. To our knowledge, serum vaspin levels have not yet been reported in predialysis patients. Carotid intima-media thickness (CIMT) is a noninvasive procedure to detect early atherosclerotic changes. The aim of this study was to evaluate serum vaspin levels in predialysis patients and their relationships with glomerular filtration rate and CIMT levels. METHODS: A total of twenty-five predialysis patients (14 females and 11 males) and 22 healthy subjects (8 females and 14 males) were enrolled in the study. Serum samples were subjected to the human vaspin RIA system. CIMT was measured by B-mode ultrasonography. RESULTS: Serum vaspin levels were significantly lower in predialysis patients than control subjects (P < .05), while CIMT levels were significantly higher (P < .001). Serum vaspin levels were found to be significantly correlated with glomerular filtration rate (r = 0.42, P < .001) and CIMT (r = -0.47, P < .05) in predialysis patients. CONCLUSIONS: This is the first report to describe the association between serum vaspin levels and CIMT in predialysis patients. We concluded that serum vaspin levels were decreased in predialysis patients than control subjects. In addition, serum vaspin levels were found to be significantly correlated with glomerular filtration rate and CIMT.

Synthesis, molecular modelling, FT-IR, Raman and NMR characterization, molecular docking and ADMET study of new nickel(II) complex with an N4-tetradentate thiosemicarbazone.

A new nickel(II) complex was synthesized by using S-propyl-thiosemicarbazide and 2-amino-3,5-dibromobenzaldehyde. The complex, obtained by the template effect of nickel ions, was structurally analysed by experimental and theoretical vibrational spectroscopy, NMR and density functional theory (DFT) calculations. By using DFT/B3LYP method with 6-311++G(d, p) basis set, the most stable molecular structure of the title molecule was calculated. The fundamental vibrational wavenumbers, IR and Raman intensities for the optimized structure of the molecule under investigation were determined and compared with the experimental vibrational spectra. The vibrational assignment was achieved using the calculated potential energy distributions of the vibrational modes. Moreover, the molecular electrostatic potential (MEP), the highest occupied molecular orbital (HOMO) and the lowest occupied molecular orbital (LUMO) energies were calculated, Molecular docking of the molecule was carried out against DNA in order to identify the potential inhibitory action of the title compound. The findings suggested that the aforementioned compound has a strong binding affinity to interact with DNA residues DT8, DC9, DG12, DG16, DA17, and DA18 through the intermolecular hydrogen bonds. Also the performed in silico ADMET analysis was the prediction of the synthesized molecule's pharmacokinetic and toxicity profile expressing good oral drug like actions and non-toxic nature. The complex has been shown to have the possibility to become a model molecule for drug development processes.Communicated by Ramaswamy H. Sarma.

Effects of immunization program on morbidity and mortality rates ofvaccine-preventable diseases in Turkey

Background/aim: This study aims to serve as a unique consolidated source in Turkey's vaccination history and as an example for other countries by objectively revealing the change in mortality and morbidity rates in Turkey following the beginning of vaccination without asserting any claim on the benefits or risks of vaccines. This unbiased research will also help health professionals identify the challenges more easily when they face with the people who hesitate to vaccinate their children. Materials and methods: Descriptive research design is adopted in this study. The coverages of vaccinations, mortality, and morbidity rates were identified through a retrospective analysis of the data provided from the Ministry of Health of Turkey. The data provided by the Turkish Statistical Institute were used for the identification of the population by the year. Mortality and morbidity rates were calculated based on these data Results: Morbidity rates, mortality rates, and vaccine coverages are all presented in years. Successful interventions have been observed in the eradication of polio, the elimination of maternal neonatal tetanus, and also in combating with other diseases. A decline in pertussis mortality from 0.59 to 0.06 along with a decline in diphtheria morbidity under to 0.0001 were recognized; additionally the last death due to poliomyelitis was observed in 1998. Only 4 deaths occurred in the measles epidemic in 2013. With the initiation of vaccination, both the morbidity of the rubella with the ratio of 3.12/100,000 and the mortality of pumps with the ratio of 25/100,000 fell to zero. Also, no death due to neonatal tetanus has been recorded since 2014. Conclusion: The present study demonstrates that many possible diseases and deaths have been prevented through vaccination studies. In this regard, this study demonstrating the importance of vaccination presents that all individuals in the society have a responsibility in this scope when the communicable diseases and wars are taken into consideration. The main responsibility is to ensure that they and their children are vaccinated against communicable diseases that are risky for society's health.

Palladium (II) complexes with thione and thioalkylated thiosemicarbazones: Electrochemical, antimicrobial and thermogravimetric investigations.

Four methoxy substitute salicylidene thiosemicarbazones were synthesized. The reaction of both thione and thioalkylated thiosemicarbazones with PdCl2 in ethanol yields ONS-coordinated chelate complexes with general formula [Pd(L)Cl]. The structures of eight compounds were characterized by using analytical and spectroscopic methods. Electrochemistry of the Pd(II) complexes was studied using cyclic voltammetric technique. The CVs of the complexes were quite complicate because of some oxidative responses of the ligands which proceed by forming conjugated -N=CH-, -HC=CH- and -N=CH-HC=CH- groups. Two cathodic responses attributed to one electron reduction of Pd(II)/(I) and Pd(I)/(0) were observed for the central ion coordinated with S atom of H3C-S- group whereas only one reduction peak appeared when the Pd(II) coordinated with S atom of >C=S group of thiosemicarbazone ligand. The latter also showed an additional anodic response assigned to Pd(II)/(III) oxidation. Thermogravimetric analysis (TGA) technique was used to investigate and compare the thermal properties of the ligands and their metal complexes. In vitro antimicrobial activity of thiosemicarbazones and their complexes was evaluated against four Gram-negative bacteria, three Gram-positive bacteria, and antifungal activity against three fungi.

Serum vaspin levels and carotid intima media thickness in pre dialysis patients.

BACKGROUND AND OBJECTIVE: Vaspin is a molecule belonging to adipokine family which is associated with insulin resistance and obesity in humans. Several studies have evaluated the serum levels of vaspin in various conditions including coronary artery disease and chronic hemodialysis patients. To our best knowledge, serum vaspin levels have not yet been studied in pre dialysis patients. Carotid intima-media thickness (CIMT) is a noninvasive procedure used to diagnose the extent of carotid atherosclerotic vascular disease. The objective of this study is to evaluate serum vaspin levels in pre dialysis patients and their relationships with glomerular filtration rate and CIMT levels. METHODS: A total of twenty-five pre dialysis patients (14 female and 11 male) and 22 healthy controls (8 female and 14 male) were included in the study. CIMT was measured through B-mode ultrasonography. RESULTS: Serum vaspin levels were significantly lower (p<0.05) and CIMT levels were significantly higher (p<0.001) in pre dialysis patients than in control subjects. Serum vaspin levels were found to be significantly correlated with glomerular filtration rate (r=0.42, p<0.001) and CIMT (r=-0.47, p<0.05) in pre dialysis patients. CONCLUSIONS: This is the first report to describe the correlation between serum vaspin levels and CIMT in pre dialysis patients. We concluded that serum vaspin levels were decreased in pre dialysis patients compared to the control subjects. In addition, serum vaspin levels were found to be significantly correlated with glomerular filtration rate and CIMT. This article is protected by copyright. All rights reserved.

Effects of Trimetazidine on T Wave Alternans in Stable Coronary Artery Disease.

BACKGROUND AND OBJECTIVES: Studies reveal that the microvolt T wave alternans (MTWA) test has a high negative predictive value for arrhythmic mortality among patients with ischemic or non-ischemic cardiomyopathy. In this study, we investigate the effects of trimetazidine treatment on MTWA and several echocardiographic parameters in patients with stable coronary artery disease. SUBJECTS AND METHODS: One hundred patients (23 females, mean age 55.6±9.2 years) with stable ischemic heart disease were included in the study group. Twenty-five age- and sex-matched patients with stable coronary artery disease formed the control group. All patients were stable with medical treatment, and had no active complaints. Trimetazidine, 60 mg/day, was added to their current treatment for a minimum three months in the study group and the control group received no additional treatment. Pre- and post-treatment MTWA values were measured by 24 hour Holter testing. Left ventricular systolic and diastolic functions were assessed by echocardiography. RESULTS: After trimetazidine treatment, several echocardiographic parameters related with diastolic dysfunction significantly improved. MTWA has been found to be significantly improved after trimethazidine treatment (63±8 µV vs. 53±7 µV, p<0.001). Abnormal MTWA was present in 29 and 11 patients pre- and post-treatment, respectively (p< 0.001). CONCLUSION: Trimetazidine improves MTWA, a non-invasive determinant of electrical instability. Moreover, several echocardiographic parameters related with left ventricular functions also improved. Thus, we can conclude that trimetazidine may be an effective agent to prevent arrhythmic complications and improve myocardial functions in patients with stable coronary artery disease.

Hepatosteatosis and carotid intima-media thickness in patients with myocardial infarction.

PURPOSE: The aim of the study was to determine the involvement of non-alcoholic fatty liver disease (NAFLD) in myocardial infarction patients and its relation with carotid intima-media thickness (CIMT). METHODS: This study consisted of 224 patients divided into three groups: those with myocardial infarction (MI), stable coronary artery disease (CAD), and normal coronary artery. Measurement of CIMT and abdominal ultrasonography for hepatosteatosis was performed in all participants. RESULTS: NAFLD was significantly more frequent among MI patients compared to the other groups. There was a significant difference between CAD and the presence of NAFLD (p < 0.05). Also, we found significant correlations between the severity of CAD and hepatosteatosis grade (r = 0.648, p < 0.001), CAD and CIMT (r = 0.594, p < 0.001), and NAFLD and CIMT (r = 0.233, p = 0.005). NAFLD was also significantly correlated with the severity of CAD (r = 0.607, p < 0.001), and the grade of NAFLD significantly correlated with CIMT (r = 0.606, p < 0.001). CONCLUSION: Patients with more severe CAD were more likely to have NAFLD. In addition, hepatosteatosis may be associated with coronary plaque instability and high fatty volume. Patients with NAFLD should be screened regularly for other cardiovascular risk factors, and the presence of fatty liver may help better classify these patients.

Association of epicardial adipose tissue thickness and inflammation parameters with CHA2DS2-VASASc score in patients with nonvalvular atrial fibrillation.

BACKGROUND: Epicardial adipose tissue (EAT), mean platelet volume (MPV), platelet-to- lymphocyte ratio (PLR), and neutrophil-to-lymphocyte ratio (NLR) have been shown to be helpful in predicting adverse cardiovascular events. However, to date, in the literature, there have been no studies demonstrating the relationship between EAT, MPV, PLR, NLR, and thromboembolism risk in atrial fibrillation (AF). Therefore, we examined the relationship between EAT, MPV, PLR, NLR, and CHA2DS2-VASc score used for the evaluation of thromboembolism risk in patients with AF. METHODS: The study included 96 consecutive patients with AF and 52 age- and sex-matched control subjects. We calculated CHA2DS2-VASc risk score for each patient and measured baseline EAT thickness, MPV, PLR, NLR, left atrial volume index, and left ventricular ejection fraction. RESULTS: The group with high CHA2DS2-VASc score had higher EAT (7.2±1.5 vs 5.9±1.2 mm, P<0.001), MPV (9.1±1.1 vs 8.4±1.0 fL, P=0.004), PLR (152.3±28.4 vs 126.7±25.4, P=0.001), and NLR (4.0±1.6 vs 3.2±1.3, P<0.001) compared to group with low-intermediate CHA2DS2-VASc score. Moreover, CHA2DS2-VASc score was found to be positively correlated with EAT (r=0.623, P<0.001), MPV (r=0.350, P=0.004), PLR (r=0.398, P=0.001), and NLR (r=0.518, P<0.001). CONCLUSION: Our study results demonstrated that EAT thickness, MPV, PLR, and NLR were associated with the thromboembolic risk exhibited by CHA2DS2-VASc score in patients with nonvalvular AF.

Structural and spectroscopic characterization of a thiosemicarbazidatodioxouranium(VI) complex: a combined experimental and DFT study.

The title thiosemicarbazidatodioxouranium(VI) compound was synthesized and characterized by FT-IR, NMR and UV-vis spectroscopies. Solid-state structure of the compound was confirmed by X-ray crystallography. Besides, the molecular geometry, vibrational frequencies and gauge-independent atomic orbital (GIAO) (1)H and (13)C NMR chemical shift values of the compound in the ground state have been calculated using the density functional theory (DFT/B3LYP) method with the 6-311++G(d,p) basis set for the C, H, Cl, N, O, S atoms and SDD pseudo-potential for the U atom, and compared with the experimental data. Using the TD-DFT method, electronic absorption spectra of the compound have been predicted at same level. As a result, a good agreement is obtained between the experimental and theoretical ones.

Transcatheter closure of tortuous aorto-right atrial fistula.

Congenital fistula between the aorta and right atrium is a rare congenital anomaly of the heart. We report a new case of this unusual communication, which was successfully closed by transcatheter embolisation using an Amplatzer duct occluder II. A 7-year-old asymptomatic girl was referred to our institute for evaluation of a murmur. Echocardiography revealed intact septae and the right coronary sinus was dilated with a fistulous tract arising from the sinus and opening into the right atrium with continuous flow into the right atrium. Computerized tomography confirmed the diagnosis and delineated the anatomy. Cardiac catheterization performed confirmed the presence of a markedly tortuous and dilated aorto-right atrial fistula. Coronary angiography demonstrated normal coronary arteries arising from the respective sinuses. The fistula was closed antegradely using an Amplatzer duct occluder II (AGA Medical Corporation, Plymouth, MN, USA). The continuous murmur had disappeared after the procedure and an echocardiogram revealed no continuous flow across the fistulous tract. The patient remained well at follow-up 3 months later.

Synthesis and antioxidant activities of transition metal complexes based 3-hydroxysalicylaldehyde-S-methylthiosemicarbazone.

The nickel(II), iron(III), oxovanadium(IV) complexes of the 3-hydroxysalicylidene-S-methyl-thiosemicarbazone (L) were obtained from the 3-hydroxysalicyldehyde-S-methylthiosemicarbazone with the R1-substituted-salicylaldehyde (R1: H, 3-OH) in the presence of Ni(II), Fe(III), VO(IV) as template ion. The ligand and its complexes were characterized by elemental analysis, electronic, UV/Vis., (1)HNMR, EPR and IR studies. The free ligand and its metal complexes have been tested for in vitro antioxidant capacity by reduction of copper(II) neocuproine (Cu(II)-Nc) using the CUPRAC method. The ligand exhibited more potent in vitro antioxidant capacity than its complexes. The obtained trolox equivalent antioxidant capacity (TEAC) value of the iron(III) complex (TEACCUPRAC=3.27) was higher than those of other complexes. Furthermore, the antioxidant activity of the free ligand and its complexes were determined by in vitro methods measuring the scavenging activity of reactive oxygen species (ROS) including hydroxyl radical (OH), superoxide anion radical (O2(-)), and hydrogen peroxide (H2O2), showing that especially the V(IV) and Fe(III) complexes had significant scavenging activity for ROS.

Synthesis, antioxidant activities of the nickel(II), iron(III) and oxovanadium(IV) complexes with N2O2 chelating thiosemicarbazones.

The nickel(II), iron(III) and oxovanadium(IV) complexes of the N2O2 chelating thiosemicarbazones were synthesized using 4-hydroxysalicyladehyde-S-methylthiosemicarbazone and R1-substitute-salicylaldehyde (R1: 4-OH, H) in the presence of Ni(II), Fe(III), VO(IV) ions by the template reaction. The structures of the thiosemicarbazone complexes were characterized by FT-IR, (1)H NMR, elemental, ESI-MS and APCI-MS analysis. The synthesized compounds were screened for their antioxidant capacity by using the cupric reducing antioxidant capacity (CUPRAC) method. Trolox equivalent antioxidant capacity (TEAC) of iron(III) complex, 1c, was measured to be higher than that of the other complexes. Other parameters of antioxidant activity (scavenging effects on •OH, O2(•-) and H2O2) of these compounds were also determined. All the compounds have shown encouraging ROS scavenging activities.

[A case of idiopathic ventricular tachycardia in a 14-year-old obese patient due to golden berry fruit extract pills for weight loss]. / Zayiflama amaciyla altin çilek meyve özü hapi kullanan 14 yasinda obez hastada gelisen bir idiyopatik ventriküler tasikardi olgusu.

Several studies have determined an association between obesity and increased risk of cardiac arrhythmia. Currently, due to the increased frequency of obesity, food-, plant-, and drug-based therapies for weight loss have gained great attention. A 14-year-old female patient presented with complaints of palpitation of one-hour onset. Blood pressure was 110/70 mmHg and peripheral pulses were present. She had been using golden berry extract pill three times a day for 10 days. The electrocardiogram showed nonsustained monomorphic ventricular tachycardia (VT). Echocardiographic examination and cardiac magnetic resonance imaging (MRI) were normal. She returned to sinus rhythm following amiodarone infusion. She refused the electrophysiologic study, which plays a vital role in the diagnosis and establishment of the appropriate therapy. Although there was no decrease in body mass index (BMI) of the patient during the two-year follow-up, she had no complaint or evidence of VT on intermittent rhythm Holter studies. This case suggests the primary role of golden berry extract use in the development of VT, rather than obesity.

Short-term effect of percutaneous recanalization of chronic total occlusions on QT dispersion and heart rate variability parameters.

BACKGROUND: QT dispersion (QTd), which is a measure of inhomogeneity of myocardial repolarization, increases following impaired myocardial perfusion. Its prolongation may provide a suitable substrate for life-threatening ventricular arrhythmias. We investigated the changes in QTd and heart rate variability (HRV) parameters after successful coronary artery revascularization in a patient with chronic total occlusions (CTO). MATERIAL/METHODS: This study included 139 successfully revascularized CTO patients (118 men, 21 women, mean age 58.3±9.6 years). QTd was measured from a 12-lead electrocardiogram and was defined as the difference between maximum and minimum QT interval. HRV analyses of all subjects were obtained. Frequency domain (LF: HF) and time domain (SDNN, pNN50, and rMSSD) parameters were analyzed. QT intervals were also corrected for heart rate using Bazett's formula, and the corrected QT interval dispersion (QTcd) was then calculated. All measurements were made before and after percutaneous coronary intervention (PCI). RESULTS: Both QTd and QTcd showed significant improvement following successful revascularization of CTO (55.83±14.79 to 38.87±11.69; p<0.001 and 61.02±16.28 to 42.92±13.41; p<0.001). The revascularization of LAD (n=38), Cx (n=28) and RCA (n=73) resulted in decrease in HRV indices, including SDDN, rMSSD, and pNN50, but none of the variables reached statistical significance. CONCLUSIONS: Successful revascularization of CTO may result in improvement in regional heterogeneity of myocardial repolarization, evidenced as decreased QTcd after the PCI. The revascularization in CTO lesions does not seem to have a significant impact on HRV.

Increased P-wave dispersion in patients with newly diagnosed lichen planus.

OBJECTIVE: Lichen planus is a chronic inflammatory autoimmune mucocutaneous disease. Recent research has emphasized the strong association between inflammation and both P-wave dispersion and dyslipidemia. The difference between the maximum and minimum P-wave durations on an electrocardiogram is defined as P-wave dispersion. The prolongation of P-wave dispersion has been demonstrated to be an independent risk factor for developing atrial fibrillation. The aim of this study was to investigate P-wave dispersion in patients with lichen planus. METHODS: Fifty-eight patients with lichen planus and 37 age- and gender-matched healthy controls were included in this study. We obtained electrocardiographic recordings from all participants and used them to calculate the P-wave variables. We also assessed the levels of highly sensitive C-reactive protein, which is an inflammatory marker, and the lipid levels for each group. The results were reported as the means ± standard deviations and percentages. RESULTS: The P-wave dispersion was significantly higher in lichen planus patients than in the control group. Additionally, highly sensitive C-reactive protein, LDL cholesterol, and triglyceride levels were significantly higher in lichen planus patients compared to the controls. There was a significant positive correlation between highly sensitive C-reactive protein and P-wave dispersion (r=0.549, p<0.001) in lichen planus patients. CONCLUSIONS: P-wave dispersion increased on the surface electrocardiographic measurements of lichen planus patients. This result may be important in the early detection of subclinical cardiac involvement. Increased P-wave dispersion, in terms of the tendency for atrial fibrillation, should be considered in these patients.
