Item TGF-β1 Genotype in Pediatric Migraine Patients(2015) Saygi, Semra; Alehan, Fusun; Erol, Ilknur; Yalcin, Yaprak Yilmaz; Atac, Fatma Belgin; Kubat, Gozde; 0000-0002-3530-0463; 0000-0002-9337-9106; 0000-0002-8522-5078; 0000-0001-6868-2165; 24619148; AAK-4825-2021; ABB-4078-2020; AAB-1203-2021; ABG-9966-2020There is no information about the role of transforming growth factor-beta 1 (TGF-1) in the pathogenesis of pediatric migraine. This study included 100 consecutive children and adolescents in whom migraine was diagnosed and 88 healthy children and adolescents. The isolated genomic DNA was used as a template for TGF-1 (-800G/A, -509C/T, 869T/C [codon 10] and 915G/C [codon 25]) genotyping. The allelic frequency of 509C/T was significantly different between control and migraine without aura patients (P = .04). Codon 10 C/T genotypic and C10 C allelic frequency of TGF-1 polymorphisms were significantly higher in migraine and migraine without aura patients versus healthy controls (P = .00; P = .00). To our knowledge, this is the first report dealing with the relationship between TGF-1 genotype and migraine in the pediatric age group. Further studies related to this subject are needed, along with a search for new therapeutic agents with anti-inflammatory properties.Item Hematologic and Bone Marrow Changes in Children with Protein-Energy Malnutrition(2014) Ozkale, Murat; Sipahi, Tansu; https://orcid.org/0000-0003-0625-1057; 23987917; A-7806-2016Background: All systems in an organism are affected by protein-energy malnutrition (PEM), but one of the worst affected is the hematopoietic system. Today PEM remains a very serious problem in developing countries. We examined the relationships between clinical features, hematological, and bone marrow changes with severe PEM from Turkey. Method: We evaluated 34 (11 females and 23 males) consecutive cases of severe PEM, with no underlying diseases aged 3-20 months. The clinical nutritional conditions of the patients were determined using the Wellcome-Trust PEM classification. Ten of the patients were in the Marasmic-Kwashiorkor (M-K) group, 10 were in the Kwashiorkor (KW) group, and 14 were in the Marasmic (M) group. Full blood count, protein, albumin, serum iron (SI), iron-binding capacity (TIBC), ferritin, vitamin B12, folic acid, complement-3 (C3), complement-4 (C4), and bone marrow were investigated in all groups. Results: Anemia was detected in 97% of patients. We determined serum iron levels were low in 67.6% of the patients, TS levels were low in 76.4% of the patients and ferritin levels were low in 20.5%. The level of vitamin B12 was normal in all patients. Bone marrow analysis showed erythroid series hypoplasia in 28.5% of patients in the M group, 50% in the KW group, and 30% in the M-K group. Marrow iron was absent in 58.8% of patients. Conclusion: The most common hematologic change in the children with PEM was anemia and major cause of anemia was iron deficiency in this study. Patients with severe PEM have normal Vit B12 and serum folate levels. Most of the patients with severe PEM had normal cellularity with megaloblastic and dysplastic changes in bone marrow due to the inadequate and imbalanced intake of protein and energy.Item Paraganglioma Presenting With Marked Proteinuria: A Case Report(2014) Emir, Suna; Demir, Haci A.; Guven, Burcu; Kacar, Ayper; Otkun, Ibrahim; 23154520Paragangliomas are rare neuroendocrine tumors that arise from sympathetic and parasympathetic paraganglia. In children, most of them are functional tumors. Presenting symptoms such as sustained or paroxysmal elevations in blood pressure, headache, sweating, and palpitations are related to catecholamine hypersecretion. A previously healthy 8-year-old boy presented with marked proteinuria, hypertension, and heart murmur. Imaging revealed an 81 x 43 x 45mm sized solid mass extending from right retroaortic area to left suprarenal region. Measurements of catecholamines suggested the diagnosis of paraganglioma. Pathologic examination confirmed the diagnosis. Complete tumor resection was performed. Proteinuria, hypertension, and cardiac signs resolved after surgery. Proteinuria has been described as a rare manifestation of paragangliomas in adult patients. This is the first case of a paraganglioma presenting with massive proteinuria in a child.Item Value of Sonographic Anterior-Posterior Renal Pelvis Measurements Before and After Voiding for Predicting Vesicoureteral Reflux in Children(2015) Demir, Senay; Tokmak, Naime; Cengiz, Nurcan; Noyan, Aytul; 0000-0002-4209-9075; 25545034; GPX-7059-2022; AAD-5713-2021; AAK-9310-2021PurposeVoiding cystourethrography (VCUG) is the gold standard for diagnosing vesicoureteral reflux (VUR), but it is important to minimize the use of VCUG because of the urinary catheterization and radiation exposure required. Ultrasound (US) observations suggest that pelvicalyceal dilatation varies according to the degree of bladder fullness in children with urinary tract infection. The aim of this study was to assess whether anterior-posterior (AP) measurements of the renal pelvis on US before and after voiding can be used as a screening tool while predicting the presence of VUR in children. MethodsThe subjects were toilet-trained children older than 4 years who required VCUG. Two groups were established based on the VCUG results: a VUR group of 40 kidney units (each unit defined as calyces and ureter) that exhibited different severities of reflux, and a control group of 68 kidney units unaffected by VUR. Prior to VCUG, US AP measurements of the renal pelvis of each kidney unit were recorded when the urinary bladder was full and again after bladder emptying. The change in AP measurement from before to after voiding was compared between the two groups. ResultsThe mean change in AP measurements from before to after voiding in the VUR group was significantly greater than that in the control group (p=0.003). ConclusionsComparing US AP measurements of the renal pelvis before and after voiding is useful for identifying children who are suspected to have VUR and thus require immediate VCUG. (c) 2014 Wiley Periodicals, Inc. J Clin Ultrasound 43:490-494 2015Item Neuromyelitis Optica in Children: A Review of The Literature(2014) Derle, Eda; Gunes, H. Nalan; Konuskan, Bahadir; Tuncer-Kurne, Asli; https://orcid.org/0000-0003-2122-1016; 26388586; AAI-8830-2021Neuromyelitis optica (NMO) is a rare and severe inflammatory disease of the central nervous system (CNS), which constitutes up to 5% of pediatric aquired demyelinating diseases. The optic nerves and the spinal cord are the most affected sites. The discovery of an autoantibody called NMO-IgG, which targets aquaporin-4, the main water channel in the CNS, gave a new direction to understanding the underlying immunologic mechanisms. This specific biomarker also helps to distinguish the disease from other demyelinating disorders. Here, we review the clinical and paraclinical features, immunological properties and treatment options of the disease as reported in the literature.Item Superoxide Dismutase and Catalase Genotypes in Pediatric Migraine Patients(2015) Saygi, Semra; Erol, Ilknur; Alehan, Fusun; Yalcin, Yaprak Yilmaz; Kubat, Gozde; Atac, Atac, Fatma Belgin; 0000-0002-3530-0463; 0000-0001-6868-2165; 0000-0002-9337-9106; 0000-0002-8522-5078; 25818327; AAK-4825-2021; ABG-9966-2020; ABB-4078-2020; AAB-1203-2021This study compared superoxide dismutase (SOD) and catalase (CAT) alleles in 97 consecutive children and adolescents with migraine to 96 healthy children and adolescents. Isolated genomic DNA was used as a template for SOD1 (35 A/C), SOD2 16 C/T, and CAT2 [(-262 C/T) and (-21 A/T)] allele genotyping. The SOD2 16 C/T genotype and C allele frequency differed significantly between controls and migraine (P = .047; P = .038). CAT -21 AA genotype and A allele frequency were significantly higher in both migraine with aura patients (P = .013; P = .004) and migraine without aura patients (P = .003; P = .001) compared to controls. To our knowledge, this is the first demonstration of differences in SOD and CAT genotypes between pediatric migraine patients and age-matched controls. Further studies on the functional implications of these genetic variants on neural antioxidant capacity and the use of antioxidant modulators for migraine treatment are warranted.Item Aspiration of An Interesting Foreign Body: Myiasis(2015) Ince, Emine; Oguzkurt, Pelin; Gezer, Hasan Ozkan; Aliskan, Hikmet Eda; Hicsonmez, Akgun; 0000-0001-9060-3195; 27735804; AAE-2282-2021; J-3197-2013Myiasis is a rare condition caused by the invasion of tissues by the larvae of flies. Many cases of myiasis involving various human organs have been reported. Tracheopulmonary or intratracheal myiasis is a very unusual and aberrant form of the disease in humans. We present a case of respiratory myiasis after aspiration of larvae by a healthy 8-month-old girl, which cannot be found in the English literature.Item Sinus Tachycardia Related To Tacrolimus After Kidney Transplantation in Children and Young Adults(2015) Erdogan, Ilkay; Bilginer, Yelda; Duzova, Ali; Besbas, Nesrin; 0000-0001-6887-3033; 0000-0002-4365-2995; 27735797; ABB-2220-2021; AAB-7679-2021; AAB-7692-2021; AAJ-2305-2021Tacrolimus is a potent immunosuppressive agent widely used after organ transplantation. In this present study we present eight patients who complained of palpitation after kidney transplantation. Eight out of 31 patients who received tacrolimus after kidney transplantation suffered from tachycardia. Resting electrocardiography, 24 hours Holter monitorization, echocardiography were performed, and serum levels of cardiac troponin T, creatine kinase, CKMB, brain natriuretic peptide and tacrolimus were measured. The median time to palpitation after kidney transplantation was 30 days in seven patients, and one patient complained of palpitation five years after transplantation. Cardiovascular assessment revealed sinus tachycardia in all patients. Beta-blocker was instituted in five patients. After two months all patients were asymptomatic and their pulse rates were within normal limits. Transient sinus tachycardia is a frequent adverse event during tacrolimus therapy in children and young adults, at therapeutic levels. Patients may benefit from beta-blockers.Item Evaluation of Rotavirus Gastroenteritis in Children: Five Years' Surveillance in Alanya, Antalya(2014) Coban, Bayram; Topal, Burhan; 25341600Rotavirus infection is the major cause of fatal diarrhea among children younger than five years. We aimed to determine the frequency of rotavirus infection according to age, gender and month of the year. From April 2008 through March 2013, 3,106 fresh stool specimens of children under the age of 16 years were tested for rotavirus antigen, and rotavirus antigen was detected as positive in 422 (13.6%) patients. Half of the patients (208/422, 49.3%) were younger than two years. 40.9% (173/422) of all rotavirus gastroenteritis cases were detected in winter months. The ratio of rotavirus positivity in all laboratory studies was highest (19.3%) in February.Item Is It Necessary To Re-Evaluate Diagnostic Criteria For Wilson Disease in Children?(2014) Sezer, Oya Balci; Perk, Peren; Hosnut, Ferda Ozbay; Kose, Serdar Kenan; Ozcay, Figen; https://orcid.org/0000-0002-8402-8208; https://orcid.org/0000-0002-5214-516X; 25599783; AAI-9346-2021; GSJ-0760-2022; ABG-5684-2020Background/Aims: The differential diagnosis of Wilson Disease (WD) is challenging, especially in children, because liver copper levels may also increase in other chronic liver diseases with bile stasis. The aim of this study is to determine urine and liver copper cut-off values to differentiate WD from other chronic liver diseases (non-WD, NWD) in children. Materials and Methods: Seventy-six patients participated in the study, 35 with WD and 41 with NWD. The two groups were divided into two subgroups according to the presence of cholestasis. At the time of diagnosis, age, sex, biochemical test results, serum ceruloplasmin, baseline 24-h urinary copper levels, liver biopsy histological findings, liver copper levels, and Child-Pugh scores were obtained from medical records. Copper content in liver tissue and copper levels in urine were measured by atomic absorption spectrometry. Cut-off values for differentiation of WD from NWD were determined by receiver operating characteristic (ROC) analysis. Results: A liver copper cut-off value of 98 mu g/g indicated WD with 91% sensitivity and 65.4% specificity (area under the curve =0.838, 95% CI: 0.749-0.927). A 24-h urinary copper cut-off value of 67.5 mu g/24h indicated WD with 85% sensitivity and 71% specificity (area under the curve =0.843, 95% CI: 0.752-0.934). Conclusion: In this study of pediatric chronic liver disease patients, copper cut-off values for distinguishing WD differed substantially from those used for diagnosis. A larger scale study is warranted to re-evaluate liver copper and 24-h urinary copper cut-offs for children with suspected WD.
