Is There An Association Between Histopathological Changes In The Lower Ureter And Renal Functions? Evaluation Of Patients Who Underwent Ureteroneocystostomy For Ureterovesical Obstruction Or Vesicoureteral Reflux, Müjdem Nur Azili, Doğuş Güney, Ayper Kaçar, Hüseyi̇n Tuğrul Ti̇ryaki̇
Turkish Journal of Medical Sciences
We aimed to assess the relationship between the histological changes of the ureterovesical junction (UVJ) and renal functions. Therefore, we evaluated histological changes of the lower ureter and renal scintigraphy findings of patients for whom ureteroneocystostomy was performed because of vesicoureteral reflux (VUR) or ureterovesical junction obstruction (UVO). Materials and methods: UVJ specimens were obtained from 18 children. We investigated the changes in neuronal innervation, muscular morphology, extracellular matrix, and apoptosis rate with renal scintigraphy findings. Results: Seven UVO and 11 VUR patients were treated. Alpha-actin expression in smooth muscle cells was found to be lower (P < 0.001) while neuronal defect was more prominent in the UVO group (P = 0.002). The renal functions decreased as the smooth muscle structural defect increased in the VUR group (P < 0.05). Conclusion: Neuronal tissue and muscle tissue were more defective in the UVO group. The decrease in neuronal fibers and muscle cells explains the pathogenesis of the obstructive group, but no difference was observed regarding the accumulation of collagen type 3 and cellular apoptosis between the VUR and UVO groups. In the VUR group, renal functions decreased while the smooth muscle defect at the distal end of the ureter increased.

Reduced arterial elasticity is an independent predictor of cardiovascular mortality in patients with end-stage renal disease (ESRD). Hemodialysis (HD) treatment per se can bring additional risk factors for vascular disease. Our study was designed to determine whether a single hemodialysis session leads to an acute alteration in parameters of arterial elasticity in ESRD. Materials and methods: In this study, 58 patients undergoing chronic hemodialysis and 29 healthy controls were enrolled. Large artery elasticity index (LAEI) and the small artery elasticity index (SAEI) were measured by applanation tonometry. The acute effect of a hemodialysis session on arterial elasticity indices was assessed …

Background/aim: There are different modalities for management of infantile hemangiomas (IHs). In this report, our aim is to evaluate whether intralesional corticosteroid treatment is associated with systemic side effects and whether this is an effective treatment modality for IH. Materials and methods: Six children treated with intralesional corticosteroids for problematic hemangiomas were included in the study. Clinical characteristics, response to treatment, weight, height, blood pressure, morning serum cortisol, and adrenocorticotropic hormone levels were recorded. Results: Each child received intralesional triamcinolone at a dose of 2 mg/kg for 2?5 injections at monthly intervals. Subjects were followed for 1 year. All patients …

Background/aim: Genetic polymorphism of CYP2D6 shows diverse pharmacokinetic and pharmacodynamic variation. Therefore, the present work was designed to study the variation in therapeutic responses to metoprolol (MP) in stage 1 hypertensive patients and also aims to verify the association of CYP2D6*4 polymorphism and response variation in an Indian population for the first time. Materials and methods: Clinically, a total of 119 hypertensive patients and 116 healthy individuals as controls were included. Patients were treated with MP extended release 25 mg tablets once daily for 2 weeks. Reduction in systolic blood pressure, diastolic blood pressure, and pulse rate were recorded before …

Background/aim: Iron, folate, and vitamin B12 serum levels are closely related with dietary habits and have an essential role in the healthy development of a fetus. We aimed to investigate hemoglobin, ferritin, folate, and vitamin B12 levels in preconceptional women in an area where a plant-based diet referred to as Mediterranean cuisine is commonly used. Materials and methods: The study population included 466 women between the ages of 18 and 45 years admitted for thalassemia screening. Sociodemographic variables and history of menometrorrhagia, pica, and dietary habits were collected. Serum vitamin B12, folate, ferritin, and hemoglobin levels were measured. Ferritin of

Background/aim: The aberrant upregulation of Forkhead box protein M1 (FOXM1) plays a fundamental role in cancer initiation by perturbing stem cell differentiation. This study aims to investigate the role of FOXM1 in epigenetic modification and gene expression of target genes in primary human oral keratinocytes, squamous cell carcinoma cell lines, and head and neck squamous cell carcinoma (HNSCC) tissue biopsies. Materials and methods: A genome-wide promoter methylation microarray was used to compare HNSCC cell line (n = 8), primary human oral keratinocytes (NOK; n = 8) transduced with FOXM1 and EGFP, and HNSCC tissue biopsies (n = 3). Seventeen Foxm1B-induced …
