Abstract
The occurrence of different types of poisoning and early diagnosis is important for therapeutic measures. In this study, we investigate the epidemiological causes of acute poisoning in children.In this retrospective descriptive study, children presented with acute poisoning during 2010-2019 to Shahid Madani Hospital were included. The Electronic Medical Record system of the hospital was accessed to obtain the data of the patients. The data included was demographic information, type of poisoning, clinical findings, complications, duration of hospitalization, parents' education status, and mortality status.Of 336 patients included in the study, the mean age of patients was 4.90±3.27 years (range: 1-12 years). There was a significant correlation between the age of the child and the type of poisoning, p=0.001. The most frequent age group was 5 years and less (69.6%). The most frequent sex group was male (58.6%). However, there was no significant correlation between the sex of the child and the type of poisoning. Parents' education and ICU admission were also associated significantly with the type of poisoning, p=0.001, respectively. The most common type of poisoning in children was medication (60.6%) which was mainly due to methadone. The mortality rate in the study was 1.2%.Our study showed that pharmacological drugs are the main cause of poisoning in our population. Age of the children is likely to be associated with the type of poisoning however, no gender difference was found in this regard was found in our study.

Abstract
BACKGROUND Heart diseases are the leading causes of mortality and congenital heart disease (CHD) is the most common birth defect reported worldwide. OBJECTIVE The aim of this study was to evaluate the incidence of arrhythmias and CHD and the association between the two, among infants and children reported to our center. METHODS This cross-sectional study included infants and children who were referred to Shahid Madani Hospital, Khorramabad. Electrocardiogram (ECG) was performed in these children to determine the type of arrhythmia and records were used to obtain demographic data and the data regarding CHD. RESULTS Of 200 children enrolled in the study, 10 children had arrhythmias, 12 had tachycardia, 5 had bradycardia, and 31 had congenital disease. Among children with arrhythmias, 1 had atrial fibrillation, 4 patients had paroxysmal supraventricular tachycardia, 1 person had right bundle branch block, 1 had ventricular tachycardia, 2 had premature ventricular contractions and 1 had junctional ectopic tachycardia. Of the 31 children with CHD, 9 patients were presented with small ventricular septal defect, 4 children had patent foramen ovale, 2 had pulmonary stenosis and 1 of the children had tetralogy of fallout, arterial and ventricular septal defects and transposition of greater arteries, respectively. CONCLUSION We reported a positive correlation between the arrhythmias and CHD. A larger number of studies collecting focusing on different age groups are therefore required to verify our findings.

Abstract
BACKGROUND Congenital heart diseases are the most prevalent congenital abnormalities in the neonates, caused by environmental and genetic factors and contributing to the leading cause of death. This study aims to evaluate the relationship between neonates with large for gestational age and increased risk of congenital heart diseases among non-diabetic mothers. METHODS In this study, 179 neonates with large gestational age in Khorramabad were enrolled where heart abnormalities were evaluated using echocardiography. RESULTS 87 neonates had more than 4000 g of birth weight with no heart abnormalities and 92 (51%) macrosomic neonates had congenital heart diseases. Statistical analysis revealed a significant relationship between birth weight and increased risk of acquiring congenital heart disease between the two groups. There was no significant relationship between birth weight, maternal age, gender, labor type and blood group between the two groups. The highest incidence of congenital heart anomalies was related to 38% of arterial septal defect (ASD) and 15.2% of ASD and VSD, respectively. CONCLUSION The most prevalent abnormality was arterial septal ASD. None of these abnormalities were associated with maternal age, birth weight and neonate gender. Future studies for congenital heart disease and neonatal birth weight are, therefore, recommended.

Abstract
OBJECTIVE Seizure is the most common neurological disorders in children, where 4-10% of the cases experience at least one seizure before the age of 16. The most frequent causes of seizures in children are fever, epilepsy, infection and brain damage. The aim of this study was to investigate the frequency of organic lesions in MRI of children with seizures unrelated to fever. MATERIALS AND METHODS This cross-sectional study included children presented with fever-unrelated seizures. The MRI was examined by a radiologist to identify abnormal findings in each patient. A researcher-made questionnaire including general information, history of head trauma, obstructed labor and the history of seizure was completed for the patients. RESULTS Of 287 children with fever-related seizure, 127 (45.7%) were male and 151 (54.3%) were female. History of seizure, history of obstructed labor, abnormal MRI, complete delay, use of antiepileptic drug and history of trauma were 22(9.9%), 1 (0.4%), 11(4%), 5(1.8%), 259(93.2%) and 12 (4.3%), respectively. Of 11 patients with abnormal MRI, 4 had MTS lesions, 2 had tumor lesions, 2 had scarring trauma, 1 had an epidural abscess and 1 had meningitis. The frequency of organic lesions had no significant differences based on gender, use of antiepileptic drug and traumatic history, but it had a significant relation with obstructed labor andthehistory of seizure. CONCLUSION The results showed that organic brain lesions in children with fever-unrelated seizure had a significant relationship with the history of seizure and obstructed maternal labor.

Abstract
Background: Dislocation of total hip arthroplasty (THA) needs prompt intervention and reduction either closed or open. It is unusual to left THA dislocated. Hence in this study, the outcomes of neglected prosthesis after THA were determined.
Methods: In this case series study, 15 neglected cases of total hips which had been left unreduced for long time (more than 3 months) were assessed. Cause of postponing reduction, femoral side and acetabular side defects, approach and type of revised prosthesis, Harris hip score (HHS), and other complications were studied.
Results: The results in this study demonstrated that financial issues were the cause of delayed attempt for treatment in 5 cases and the other 10 cases had delay for treatment, because they searched for a specialist to accept performing an operating on them. There were some acetabular side and femoral side defects. By Paprosky classification, in femoral side, there were 6 defects: four type 2, one type 3A, and one 3B. In acetabular side, there were 10 defects (three type 1, one type 2a, three type 2b, one type 3a, and two type 3b). In one developmental dysplasia of the hip (DDH) case, previous osteotomy site was revised (distal segment rotated and then refixed)
Conclusion: Totally, according to the obtained results, it may be concluded that outcomes were relatively good in neglected prosthesis cases after THA. However, recognition of high-risk cases and reduction of delay time may improve the outcomes.

Abstract
AIMS Congenital heart disease is among the most common congenital anomalies in pediatrics. The aim of this study was to evaluate the prevalence of congenital heart disease in children in Khorramabad, Iran. METHODS This is a descriptive-cross sectional study where all the children diagnosed with congenital heart disease by echocardiography were enrolled to the Shahid Madani Hospital. Patient information was collected by means of a questionnaire. Of 1600 children who underwent cardiac counseling, 9.75% presented congenital heart disease. These were most prevalent among the children of 0-28 days of the age (14.7%) and least in children aged 1 month-1 year. According to this study, atrial (20.3%) and ventricular septal defect (10.5%) were the most common heart defects, respectively. Among signs and symptoms of cardiac disease, 49.1% of children had cyanosis, 89.7% with increased CT (cardiothoracic)-ratio, and 82.7% of had heart murmur. Congenital heart disease was more prevalent in male infants (58%) and 6.6% patients had heart failure and 1.4% had other congenital conditions, such as Down syndrome. RESULTS According to our findings, atrial and ventricular septal defects are the most common congenital heart anomalies, respectively, in pediatric patients in Khorramabad.

Abstract
BACKGROUND Evaluation of risk factors associated with coronary artery disease and cardiac health in hemophilia patients is necessary to prevent the onset of ischemic heart disease. In this study, we evaluated the cardiovascular status of hemophilic patients in Lorestan province for the early onset of ischemic heart disease. METHODS In this cross-sectional descriptive study, a total of 80 patients presenting severe hemophilia, a detailed questionnaire-based investigation was conducted to analyze the prevalence of cardiovascular risk factors in severe hemophilic patients. In patients with hemophilia, body mass index (BMI), blood pressure, diabetes, LDL, cholesterol and HDL, the risk of cardiovascular death was estimated using a predictive risk predictor algorithm of Europe SCORE. RESULTS The mean age of the patients was 25 years, where all the patients were non-diabetic. Echocardiography did not show any wall motion abnormality and changes in the T wave and dysrhythmia were also not seen by ECG. 7 patients had high blood pressure, 11 had abnormal HDL, and 1 had abnormal LDL. In this study, serum LDL and HDL levels were not significantly correlated with age and BMI. Conversely, age and BMI were significantly associated with hypertension. Hypertension was observed in people over the age of 25 years and in overweighed individuals. 78.8% had normal BMI and 21.3% were overweighed. There was no significant correlation between serum LDL, serum HDL, and blood pressure and sex. The levels of abnormal LDL and HDL were higher in men than in women. CONCLUSION ECG findings from our study did not report any significant cardiac abnormalities among hemophilic patients. Cardiovascular risk factors were not significantly correlated in these patients.

Abstract
AIM Favism is characterized as acute anemia, due to Glucose-6-phosphate dehydrogenase (G6PD) deficiency as a result of fava beans intake. It is associated with paleness, jaundice, and hemoglobinuria. In this study, signs, symptoms and therapeutic findings of the patients with hemolysis due to G6PD deficiency were investigated in Shahid Madani Hospital of Khorramabad, Lorestan. METHODS This is a single-center cross-sectional descriptive study that was conducted on all children with G6PD deficiency-induced hemolysis. RESULTS 308 children (64.3% male and 35.7% female) were included in this study. The most common complaint was jaundice (82.5%) and the most common cause of hemolysis was the intake of fava bean (85.7%). 68% of the children were treated with hydration/fluid therapy. Blood transfusion was conducted in 36.36% of the cases and the mean of blood administered was 18.9 cc/kg. CONCLUSION In this study, hydration therapy was performed in most of the children presenting favism. Also, the incorrect calculation of the amount of blood needed for transfusion increased the frequency of blood transfusions and prolonged hospitalization time.

Abstract
One of the rare complications associated with phototherapy include redistribution of blood flow that can alter cardiac output in infants. The aim of this study was to evaluate the effects of phototherapy on left ejection fraction in infants with jaundice. Twenty-nine infants admitted in Shahid Madani Children Hospital for receiving phototherapy were included in this study. Echocardiography was performed in the participants, immediately before and 24 hours after the treatment. Nineteen infants were reported to have decrease in the stroke volume following the treatment. The mean levels of stroke volume before and after phototherapy were 6.99 ± 2.17 and 6.55 ± 1.85 L/m 2 , respectively ( p = 0.011). Phototherapy can reduce left ejection fraction in newborn infants with hyperbilirubinemia.

Abstract
Objectives Reduced levels of α-Klotho is associated with the pathogenesis of various diseases including diabetes. In type I diabetes, decrease in Klotho leads to apoptosis of β-cells of pancreases. The aim of this study was to evaluate the levels of α-Klotho in type I diabetic pediatric patients. Methods In this cross-sectional single centered study, 46 patients presenting type I diabetes mellitus (case group) and 78 control group under the age of 12, referred to our clinic were included in our study. Serum levels of soluble Klotho were measured by sandwich ELISA in case and control groups. Statistical analysis was conducted for the data recorded via questionnaire. Results Mean age of the patients in the case and control group was 7.65 ± 3.09 and 7 ± 2.37, respectively. Type I diabetes patients had a significant reduction in the levels of serum Klotho, as compared to controls (p<0.001). However, gender and age-based comparison between patient and control group was not significant. Conclusions This study reports a significant decrease in the serum levels of α-Klotho in type 1 diabetic patients. Low levels of Klotho can be associated with diabetic nephropathy and other comorbidities in these patients.

Abstract
Objective The aim of this study is to determine the distribution of the results of routine laboratory tests for the diagnosis of pneumonia in children in Khorramabad. Methods This is a cross-sectional study and was performed on 650 children with pneumonia who were referred to Shahid Madani Hospital. From patients' test results, the following data were recorded: whether the results were normal or not, age, sex, serotype, history of diabetes mellitus, and the presence of urinary and digestive tract symptoms. Results There was no difference in the prevalence of pneumonia, gender-wise, whereas 40% of the patients were under 2 years. In addition, 53.7% of the patients were presented with leukocytosis. From the blood test, blood urea nitrogen, creatinine, sodium, and potassium were normal in most of the patients. Stool examination, urine analysis, urine culture, erythrocyte sedimentation rate, C-reactive protein, and blood sugar were also normal in these patients. Conclusion Children under the age of 2 years are more susceptible to lung infections. Findings from blood tests such as leukocytosis are useful for making initial diagnosis other than computed tomography scan. Other lab tests might not give any useful results. In addition, a closer examination of the urinary system and digestive tract involvement is recommended, prior to urine or stool analysis.

Abstract
Tramadol is an opioid agonist with activation monoaminergic properties. It can be administered orally, rectally, intravenously, or intramuscularly as a centrally acting analgesic. Liver injury can lead to changes in the metabolism of tramadol. In this study, the rate of tramadol metabolism in rats with damaged liver induced by ethanol and acetaminophen was assessed in a recirculation perfusion system. Acetaminophen is a mild analgesic and antipyretic agent, which can cause centrilobular hepatic necrosis in toxic doses, whereas alcohol causes death due to liver diseases. Alcoholic liver disease (ALD), such as alcoholic fatty liver, alcoholic hepatitis, and alcoholic fibrosis, is the most common liver disease. The aim of this study was to investigate the alteration in tramadol metabolism in different hepatotoxicity conditions in animal models. Male rats were randomly assigned to three groups. The control group received normal saline, group 2 received acetaminophen at the dose of 250 mg/kg/day, and group 3 received ethanol at the beginning dose of 3 g/kg/day, which was slowly increased to 6 g/kg/day. Tramadol was added to the perfusion solution at the concentration of 500 ng/mL. Samples were collected during 180 min, and analyte concentrations were determined by the High-Performance Liquid Chromatography (HPLC) method. The concentration of tramadol and its three main metabolites, O-desmethyltramadol (M1), N-desmethyltramadol (M2), and N,O-didesmethyltramadol (M5), were determined in perfusate samples. Ethanol and acetaminophen significantly affected the pattern of weight gain and liver weights before perfusion and caused a significant increase in enzyme activities. Moreover, histopathologic examination revealed that ethanol and acetaminophen caused liver damage. An increase in the elimination half-life and reduced clearance rate of tramadol were seen in the acetaminophen and ethanol groups, in comparison to the control group. Additionally, significant reductions in the Area Under the Curve (AUC) of metabolites of tramadol (M1, M2, and M5) were observed in the acetaminophen and ethanol groups in the perfused rat liver model. Liver damage caused by ethanol and acetaminophen during 45 days in animals leads to a significant reduction in the level of tramadol metabolites. Therefore, in patients with liver damage caused by ethanol and acetaminophen, caution needs to be considered when prescribing tramadol.

Abstract
People are exposed to a number of environmental, occupational, and therapeutic toxic agents which may be natural or man made. These hazardous substances may manifest as direct side effects on the function of organs or indirectly induced alteration of gene expression, cancer-associated metabolic pathways, and/or alter homeostasis. Lycopene, as a one of the most potent antioxidant, is found in fruits and vegetables. High-intake of lycopene has been shown to be effective in decreasing the risk of both natural toxins including mycotoxins, bacterial toxins, and chemical toxins including heavy metals, pesticides as well as herbicides. Recently, there is growing attention in understanding the mechanisms of the phytochemicals and carotenoids as antioxidative, antiapoptotic, radical scavenging, and chelating agents and their roles in the modulation of inflammatory pathways. This review summarizes available data from several recent studies about lycopene and its role against chemical and natural toxicants. © 2018 BioFactors, 45(1):5-23, 2019.

Abstract
BACKGROUND We aimed to recognize the predictors of long-term major adverse cardiac events (MACE) in the elderly candidates for elective percutaneous coronary intervention (PCI) at our center. METHODS In this retrospective cohort study, we reviewed the data of the elderly (age ≥65 years) candidates for elective PCI who met our study criteria, at Tehran heart center between 2004 and 2013. Demographic, anthropometric, clinical, angiographic, procedural and follow-up data of the enrolled patients were retrieved from the angiography/PCI databank of our center. The study characteristics of the patients with or without MACE were compared in a univariable Cox-regression analysis. A multivariable Cox-regression model was applied using variables selected from the univariable model to determine the predictors of MACE. RESULTS We reviewed the data of 2772 patients (mean age=70.8±4.7 years, male sex=1726 patients [62.3%]) from which 393 patients (14.4%) developed MACE. In the multivariable regression model, female sex was a protective factor for MACE (hazard ratio [HR]=0.701; P=0.001), while presence of diabetes mellitus (HR=1.333; P=0.007), family history of coronary artery disease (CAD) (HR=1.489; P=0.003) and plain balloon angioplasty (HR=1.810; P=0.010) were independent risk factors for MACE. CONCLUSION PCI is a safe and effective method of revascularization in the elderly patients, and some clinical and procedural factors can predict MACE in this group of patients.

Abstract
Vascular endothelial growth factor (VEGF) is a key regulator of vascular formation and a predominant protein biomarker in cancer angiogenesis. Owing to its crucial roles in the cancer metastasis, VEGF detection and quantification is of great importance in clinical diagnostics. Today, there exist a wide variety of detection strategies for identifying many types of disease biomarkers, especially for VEGF. As artificial single-stranded DNA or RNA oligonucleotides with catalytic and receptor properties, aptamers have drawn lots of attention to be applied in biosensing platforms due to their target-induced conformational changes as well as high stability and target versatility. So far, various sensitivity-enhancement techniques in combination with a broad range of smart nanomaterials have integrated into the design of novel aptasensors to improve detection limit and sensitivity of analyte detection. This review article provides a brief classification and description of the research progresses of aptamer-based biosensors and nanobiosensors for the detection and quantitative determination of VEGF based on optical and electrochemical platforms.

Abstract
Background Formic acid (formate) is the main reason for toxicity and death through methanol poisoning. The simultaneous determination of methanol, ethanol, and formate in the body can help to discover the cause of death and is useful in the diagnosis of acute methanol poisoning. The measurement of formate is not yet available in Iran. With regard to the increasing rate of methanol poisoning and its related mortality in Iran, as well as the main role of formate in methanol poisoning, this study was designed to set up an analytical method for the concurrent determination of ethanol, methanol, and formate. Methods Following the modification of a previously developed gas chromatography method, vitreous and blood samples of 43 postmortem cases with a history of methanol intoxication were collected over a period of 2 years at the Legal Medicine Organization of Mashhad. Thereafter, ethanol, methanol, and formate concentrations were measured by headspace GC/FID. Formate esterification was performed by the methylation of formate with sulfuric acid and methanol. In order to confirm the esterification method for the production of methyl formate, we used gas chromatography with a mass detector (GC/MS) because of its higher sensitivity and accuracy. Furthermore, the correlations between formate and methanol concentrations in blood and vitreous samples, and between formate and methanol were investigated. Results A significant relationship was found only between methanol concentrations in blood and vitreous samples (P < 0.03). Conclusions In postmortems, with the passage of time since alcohol ingestion, the measurement of only methanol concentration cannot determine the degree of toxicity or the cause of death. Therefore, using the present analytical method and measurement of formic acid, we can estimate the degree of toxicity and cause of death.

Abstract
In the present study, quantitative relationships between molecular structure and anti-tubercular activity of some 5-methyl/trifluoromethoxy-1H-indole-2,3-dione-3-thiosemicarbazone derivatives were discovered. The detailed application of an efficient linear method and principal component regression (PCR) for the evaluation of quantitative structure activity relationships of the studied compounds is demonstrated. Components produced by principal component analysis were used as the input for a linear model development. Results indicate a linear relationship between the principal components obtained from molecular descriptors and the inhibitory activity of this set of molecules. The maximum variance in the activity of the molecules in PCR method was 73%. The performance of the developed model was tested by several validation methods.
