Serum albumin and von Willebrand factor: possible markers for early detection of vascular damage in children undergoing peritoneal dialysis.

PURPOSE: Cardiovascular diseases are the main causes of morbidity and mortality in children with end-stage renal disease and the relationships among several relevant potential biomarkers were investigated in pediatric peritoneal dialysis patients. METHODS: Serum homocysteine, von Willebrand factor (vWF), apolipoproteins A and B, lipoprotein-a, high sensitive-CRP, hemoglobin, phosphorus and parathyroid hormone (PTH) levels, systolic (SBP) and diastolic (DBP) blood pressure, carotid intima-media thickness (cIMT) and left ventricular mass index (LVMI) were measured in 21 pediatric peritoneal dialysis patients and control subjects. RESULTS: All risk factors were higher in patients than controls. LVMI values were negatively correlated with hemoglobin and positively correlated with PTH and phosphorus levels (p=0.007, r= - 0.573; p=0.013, r= 0.532 and p=0.035, r= 0.461, respectively). cIMT was negatively associated with serum albumin and positively correlated with vWF levels and with SBP and DBP (p=0.006, r= - 0.578; p=0.039, r= 0.453; p=0.02, r= 0.503; p=0.024, r= 0.491, respectively). Robust regression analyses showed that hemoglobin was an independent predictor of LVMI and serum albumin was an independent predictor of cIMT. CONCLUSION: Only uremia-related factors were independent risk factors for predicting LVMI and cIMT. Hemoglobin level may be a critical factor in the development of left ventricular hypertrophy; therefore, effective treatment of anemia is crucial. Low serum albumin and high hsCRP and vWF levels, and their correlations with cIMT, indicate these patients could be at risk of developing malnutrition-inflammation-atherosclerosis syndrome and suggest that serum albumin and vWF levels may be useful markers for early detection of vascular damage.

Short-Term Outcomes of Patent Ductus Arteriosus Closure With New Occlutech® Duct Occluder: A Multicenter Study.

AIM: Over the past 2 decades, transcatheter occlusion of patent ductus arteriosus (PDA) with coils and the duct occluders evolved to be the procedure of choice. A new device, the Occlutech PDA® occluder (ODO) device has been designed. Herein, we aimed to evaluate the characteristics and short-term results of patients who underwent transcatheter closure of PDA using the ODO. METHODS: We reviewed the clinical records of 60 patients from different centers in Turkey between December 2013 and January 2016. The medical records were reviewed for demographic characteristics and echocardiographic findings. Device size was selected on the narrowest diameter of PDA. RESULTS: The median patient age was 2.5 years (6 months-35 years), and median PDA diameter was 2.5 mm (1.2-11 mm). Fifty-eight of 60 patients (96.6%) had successful ODO implantation. The occlusion rates were 37/58 (63.7%) at the end of the procedure, 51/58 (87.9%) at 24-48 hours post-procedure, and 57/58 (98.2%) on echocardiography at a median follow-up of 7.6 months. CONCLUSION: Our results indicate that transcatheter closure of PDA using the ODO is effective. Larger studies and longer follow-up are required to assess whether its shape and longer length make it superior to other duct occluders in large, tubular, or window-type ducts.

Determining the Independent Risk Factors and Mortality Rate of Nosocomial Infections in Pediatric Patients.

The objective of this study was to determine the rate, independent risk factors, and outcomes of healthcare-associated infections in pediatric patients. This study was performed between 2011 and 2014 in pediatric clinic and intensive care unit. 86 patients and 86 control subjects were included in the study. Of 86 patients with nosocomial infections (NIs), there were 100 NIs episodes and 90 culture growths. The median age was 32.0 months. The median duration of hospital stay of the patients was 30.0 days. The most frequent pathogens were Coagulase-negative Staphylococcus, Acinetobacter spp., Klebsiella spp., and Candida spp. Unconsciousness, prolonged hospitalization, transfusion, mechanical ventilation, use of central venous catheter, enteral feeding via a nasogastric tube, urinary catheter, and receiving carbapenems and glycopeptides were found to be significantly higher in NIs patients. Multivariate logistic regression analysis showed prolonged hospitalization, neutropenia, and use of central venous catheter and carbapenems as the independent risk factors for NIs. In the univariate analysis, unconsciousness, mechanical ventilation, enteral feeding, use of enteral feeding via a nasogastric tube, H2 receptor blockers, and port and urinary catheter were significantly associated with mortality. In the multiple logistic regression analysis, only mechanical ventilation was found as an independent predictor of mortality in patients with NIs.

Teething and affecting factors: experiences from Turkey.

BACKGROUND: The aim of this study was to investigate the experiences of Turkish mothers in teething period and the factors affecting teething. METHODS: This study was performed by filling in questionnaire forms with a face-to-face interview technique with the mothers of 792 patients presenting to the outpatient clinics of pediatrics of Fatih (Turgut Ozal) University Faculty of Medicine between 1 April and 31 July 2012. RESULTS: This study was conducted in a total of 792 children (mean age: 24.2±7.9, range 12-42 months; 430 males). Of the study population, 6.1% had a family history of premature teething, 9.7% had a family history of delayed teething, 98% had been breastfed, 91.9% had used vitamin D, 67.6% had used iron supplements, and 3.9% had fluorine use. The first teething was at 7.8±2.5 months and the first teeth to appear was the anterior lower incisor (58.7%). The symptoms the patients had during teething were irritability (64.9%), fever (64.1%), increased mastication (61.6%), increased salivation (58.2%), and diarrhea (45.6%). The rate of admission to a physician with these complaints was 19.6%. The factors affecting the teething time were a family history of premature or delayed teething and birth with natal tooth, and male gender. CONCLUSIONS: In this study we found that nutritional or local factors were not effective on teething time. Teething period was characterized by nonspecific symptoms including irritability, subfebrile fever, increased mastication and salivation, and diarrhea. Linear regression analysis revealed that male gender and a family history of premature teething were the factors responsible from a shortening in teething time.

Urinary Kidney Injury Molecules in Children with Iron-Deficiency Anemia.

BACKGROUND: The aim of this study was to investigate the urine levels of human kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), N-acetyl-ß-D-glucosaminidase (NAG), and liver-type fatty acid-binding protein (L-FABP) in children with iron-deficiency anemia (IDA). MATERIAL AND METHODS: Thirty-five children with IDA and 32 matched healthy controls were recruited. We assessed complete blood count, serum iron, iron-binding capacity, ferritin, serum levels of urea, creatinine (Cr), sodium (Na), potassium (K), calcium (Ca), and glucose levels. Estimated glomerular filtration rate (eGFR) was calculated. Urinary NAG, NGAL, KIM-1, and L-FABP were measured and divided by urine creatinine for comparisons. RESULTS: There were no significant differences in serum urea, Cr, or eGFR between the IDA group and the control group (p>0.05, for all). IDA patients had significantly higher urine NGAL/Cr, L-FABP/Cr, KIM-1/Cr, and NAG/Cr compared with the control group (p<0.05). There were significant negative correlations between hemoglobin, hematocrit, red blood cell count, and urine NGAL/Cr, NAG/Cr, L-FABP/Cr, KIM-1/Cr levels (p<0.05). CONCLUSIONS: Higher urinary kidney injury molecule levels in IDA patients suggest a possible subclinical renal injury in pediatric IDA patients whose renal functions and serum electrolytes were normal.

Management of intestinal bleeding with single-dose cyclophosphamide in Henoch-Schönlein purpura.

In these case series, we report on six children (3 girls, 3 boys) aged 5-13 years with Henoch-Schönlein purpura (HSP) who developed severe gastrointestinal (GI) bleeding resistant to both 2 mg/kg or pulse (10-30 mg/kg) i.v. methylprednisolone. All patients responded to single-dose (500 mg/m(2) ) i.v. cyclophosphamide (CPA) and none of them developed new GI bleeding after CPA treatment. No patients required surgical intervention. Single high-dose CPA may be beneficial in HSP with severe GI involvement, in which bleeding is non-responsive to high-dose steroids.

Serum galectin-3 levels in children with chronic hepatitis B infection and inactive hepatitis B carriers.

BACKGROUND: Chronic hepatitis B virus (HBV) infection is common worldwide. Follow-up of patients by the use of non-invasive techniques may be valuable in clinical practice. The aim of this study was to investigate serum galectin-3 (GAL-3) levels for monitoring disease status in children with chronic HBV infection. MATERIAL/METHODS: Thirty-two patients with chronic hepatitis B (CHB), 30 inactive HBV carrier patients, and 30 matched healthy controls were enrolled in the study. We performed basic laboratory tests: serum glucose, albumin, alanine aminotransferase (ALT), aspartate aminotransferase, gamma-glutamyl transferase (GGT), total bilirubin, prothrombin time, and activated partial thromboplastin time. In addition, serum GAL-3 levels were measured by ELISA technique. RESULTS: Significantly higher serum GAL-3 levels (16.5±3.6, 1.1±0.3, 0.7±0.5 ng/ml, respectively, p<0.001) and ALT levels (80.2±30.6, 26.8±12.6, 28.1±4.4 IU/L, respectively, p<0.001) were found in the CHB group compared with the inactive carriers and the control groups. There were no significant differences in ALT levels and GAL-3 levels or between inactive HBV carriers and the control groups (p>0.05, for each). Significantly higher GGT levels were found in the CHB group (51.3±27.5 IU/L) compared with the inactive HBV carriers (35.7±10.1 IU/L) and the control group (31.3±9.5 IU/L) (p<0.001, and p=0.004, respectively). A significant correlation was found between GAL-3 and ALT levels in the CHB group (r=0.82, p<0.001). CONCLUSIONS: Our results suggest that serum GAL-3 level may be a beneficial indicator of chronicity in hepatitis B infection in children.

Assessment of epicardial adipose tissue thickness and the mean platelet volume in children with familial Mediterranean fever.

BACKGROUND: Familial Mediterranean fever (FMF) is an inflammatory disease, which is suggested to be associated with increased risk of atherosclerosis. Epicardial adipose tissue (EAT) thickness and the mean platelet volume (MPV) are parameters used in prediction of atherosclerotic risk in various conditions. These parameters were evaluated in children with FMF and compared with healthy controls. METHODS: Forty-five patients with FMF and 54 age- and gender-matched healthy controls were assessed. Duration of symptoms, age at diagnosis, duration of delay in diagnosis, frequency and duration of FMF attacks, disease severity scores, response to colchicine therapy, MEditerraneanFeVer (MEFV) gene mutations, and MPV values were recorded. EAT thicknesses were measured by echocardiography. RESULTS: Epicardial adipose tissue thicknesses of the children with FMF were found to be significantly greater than that of controls (5.1 ± 1.4 vs. 4.5 ± 0.9 mm, p=0.036). FMF patients had significantly higher MPV values compared with the controls (7.8 ± 1.1 vs. 7.3 ± 1.4 fl, p=0.044). Age at diagnosis, duration of delay in diagnosis, and MPV values were found to be correlated with EAT thickness in the patient group (r=0.49, p=0.001 for the former parameters and r=0.32, p=0.04 for MPV). CONCLUSION: Epicardial adipose tissue thickness and MPV values seem to be increased in children with FMF. These findings may indicate an increased risk of atherosclerosis in FMF patients.

Usefulness of mean platelet volume and neutrophil-to-lymphocyte ratio for evaluation of children with Familial Mediterranean fever.

BACKGROUND: Familial Mediterranean fever (FMF) is an autoinflammatory disease characterized by recurrent attacks of serositis, fever, and rash. Clinical and subclinical inflammatory processes may contribute to atherosclerosis in FMF patients, with mean platelet volume (MPV) as a potential indicator for atherosclerosis risk and neutrophil-to-lymphocyte ratio (NLR) as a marker for subclinical inflammation in these patients. In this study, we investigated whether MPV can be used as an indicator for atherosclerosis risk and if NLR is a marker for subclinical inflammation in FMF patients. MATERIAL AND METHODS: The study consisted of 75 FMF patients in attack, 157 attack-free patients, and 77 healthy controls. White blood cell count neutrophil-to-lymphocyte ratio, platelet count, MPV, PDW C-reactive protein levels, and erythrocyte sedimentation rate were recorded. RESULTS: There were no significant differences between attack, attack-free, and control groups in terms of mean MPV and PDW value. NLR value was higher in the attack group. NLR value was similar in attack-free and control groups. CONCLUSIONS: We found that MPV and PDW values are similar in FMF patients and healthy controls. NLR was higher in FMF patients in the attack period. Therefore, our results suggest that MPV and PDW values do not predict atherosclerosis risk in pediatric FMF patients, and NLR may be an indicator for attack period but not attack-free period.

The evaluation of children with prolonged cough accompanied by American College of Chest Physicians guidelines.

INTRODUCTION: In children, coughs lasting longer than 4 weeks are considered to be chronic, with etiological factors varying widely. OBJECTIVE: This study included children with chronic cough who were followed for 1 year. All cases were evaluated with the guidance of the American College of Chest Physicians (ACCP), and etiological factors were analyzed. METHODS: The study included 270 children between the ages of 2 months and 14 years. Their presenting symptoms, physical examination findings and laboratory data were recorded. All patients underwent laboratory tests including direct chest X-ray and spirometric measurements. Several patients required additional advanced examinations such as a sweat test, determination of immunoglobulin levels and bronchoscopy. Patients were reevaluated according to ACCP recommendations, and etiological factors were investigated. RESULTS: The total of 270 patients were included in the study included 43.3% (n=153) females with a mean age of 6.5 ± 2.3 years (7 months to 17 years). After a 1-year follow-up of patients, we determined that the most common etiologic factors were asthma (27%), asthma-like syndrome (15.5%) and gastroesophageal reflux (10%). Other etiological factors included upper airway cough syndrome and protracted bronchitis, respectively. CONCLUSION: The use of a standardized clinical approach such as the ACCP increases the possibility for fast and accurate diagnosis during the treatment of children with chronic cough, and the use of these guidelines should be required.

Bacillus Calmette-Guérin is a preventive factor in mortality of childhood tuberculous meningitis.

OBJECTIVES: Studies have been done that have focused on the efficacy of bacillus Calmette-Guérin (BCG) vaccination in the prevention of cases of childhood tuberculous meningitis (TBM). However the efficacy of the vaccination in the prevention of mortality has not been sufficiently evaluated. This study aimed to determine the main features of TBM cases in childhood and to evaluate the factors related to mortality, proving the protective effect of BCG vaccination in childhood TBM. METHODS: In a retrospective approach, all consecutive cases of TBM in children that occurred between 1997 and 2005, at Dicle University Hospital, were studied. The following data were evaluated: demographic aspects, admission symptoms, radiology and laboratory findings, BCG vaccination status, tuberculin skin test (TST) positivity, and mortality rates. RESULTS: In total, 172 cases of childhood TBM were evaluated (mean age 53.3±55.7 months; 109 boys (63.4%)). The majority of these cases (70.4%) had typical TBM symptoms on admission. BCG vaccination data were available for 152 (88.4%) cases and 29 of them (19.1%) were positive. The TST was performed for 143 patients (83.1%) and 28 (19.6%) were found positive. Hydrocephalus was identified in 118 patients (68.6%) on computed tomography examination. A shunt was placed in 79 cases (45.9%). In total, 24 patients (14.0%) died in the hospital. TST negativity was a significant factor for mortality (p=0.012). BCG positivity was found to be a preventive factor from mortality (p=0.05). CONCLUSIONS: BCG vaccination is effective in the prevention of TBM-associated mortality in childhood. TST negativity may be a sign of a poor prognosis in TBM cases.

Use of complementary and alternative medicine in children who have no chronic disease.

AIM: In this study, we aimed to evaluate complementary and alternative methods of medicine, determine the frequencies of usage of these methods and investigate the factors which have an impact on their usage. MATERIAL AND METHODS: The study was conducted between October, the 15(th) and November, the 15(th) 2012. Approval was obtained from the local ethics committee (08.10.2012/732). The study form prepared was applied to the mothers of the children who presented to our general outpatient clinic and had no chronic disease. The data were recorded in SPSS for Windows v.16 program. Descriptive statistics, chi-square, Mann-Whitney U and logistic regression analyses were applied. A p value of <0.05 was considered significant. RESULTS: Two hundred and six children were included in the study. Complementary and alternative medicine was used in 83% of the patients. Wearing an evil eye (45%) bead and prayer (35%) to protect from the evil eye were the most commonly used methods. The most common medical conditions which caused to use of complementary and alternative medicine included anemia, diarrhea, constipation and cough. Belief-based application were being used in 73% of the patients and herbal methods were being used in 57%. In 18% of the patients, interventional methods including cutting had been performed. No difference was found between the patients in whom these methods were used and not used in terms of familial income, education levels of the parents, family type and residence (p>0.05). CONCLUSIONS: Complementary and alternative methods of medicine are applied substantially frequently in children. Physicians should have information about these methods in terms of their effects and side effects and warn families and especially mothers about potential risks.

Changes in growth pattern, leptin ghrelin and neuropeptide Y levels after adenotonsillectomy in prepubertal children.

AIM: The purpose of this prospective study was to evaluate whether surgical treatment of adenotonsillar hypertrophy has an effect on growth patterns and circulating concentrations of leptin, ghrelin and neuropeptide Y, which are all significant in energy balance. MATERIALS AND METHODS: The study group consisted of 20 children who underwent tonsillectomy with or without adenoidectomy due to chronic adenotonsillar hypertrophy. The ages ranged from 4.3 to 9.2 years with normal weight. The healthy control subjects consisted of 30 age- and sex-matched children (control group) with ages between 3.2 and 8.1 years. Serum levels of leptin ghrelin and neuropeptide Y were measured in the preoperative period and at the end of the postoperative period, which was 6 months in the study group, serum levels were only measured during the first examination in the control group. RESULTS: When the study group (preoperative) is compared with the control group, it is observed that the leptin and ghrelin levels were higher in the study group and that the neuropeptide Y levels were similar (p=0.01, p=0.005, p=0.19, respectively). When the preoperative and postoperative anthropometric data were compared, it was observed that weight, height, body mass index (BMI) and BMI-standard deviation score (SDS) values increased in the 6th month postoperatively (p<0.001, p<0.001, p=0.01, p=0.03, respectively). However, the leptin, ghrelin and neuropeptide Y levels were similar (p=0.70, p=0.12, p=0.60, respectively). CONCLUSION: Following adenotonsillectomy, an increase in weight and height occurred in the children. In the postoperative period, dietary and lifestyle suggestions as well as growth monitoring might be useful.

[A rare cause of afebrile convulsion: rotavirus gastroenteritis]. / Una causa infrecuente de convulsión afebril: gastroenteritis por rotavirus.

Rotavirus is the most common infectious diarrhea that causes important mortality and morbidities in small children, severe dehydration and electrolyte imbalance. Extraintestinal signs are rare in rotavirus infections. Recently, afebrile seizures associated with rotavirus gastroenteritis but without encephalopathy, dehydration, electrolyte imbalance or hypoglycemia have being reported. In this article, the fact that rotavirus, which is seen commonly in our country, can be confronted with various clinical manifestations was emphasized by reminding that it can be seen not only in infants with neurologic and systemic disease but also in healthy infants.

The clinical findings and prophylactic treatment in children with factor X deficiency.

Factor X (FX) is the component of both extrinsic and intrinsic coagulation cascade and is the first enzyme of the common pathway which results in thrombus. Congenital FX deficiency (FXD) is an extremely rare coagulation defect. In this study, we aimed to investigate the clinical and laboratory data of the patients diagnosed with FXD. The files of the 15 patients (7 female, 8 male) diagnosed and followed up for FXD within the last 4 years were evaluated retrospectively. The mean age of the patients was 29 months (min-max:1-144 months). The most presenting complaints were easy bruisability (n = 8; 53%) and epistaxis (n = 8; 53%). FX levels were <1% in six patients, 1-5% in four patients, and >5% in five patients. Heparin added-Protrombin Complex was used for prophlaxy (n = 11; 73%). Any treatment-related complication was not observed. Heparin-added PCC can be used safely for effective prophlaxy. We suggest that family history is important when considering prophlaxy and in patients with life-threatening bleeding or with FXD sibling the prophlaxy should be introduced in the early course.
