Abstract

Background: The aim of this study was to describe the one-decade experience in Percutaneous Nephrolithotomy surgery in children with kidney stones in Tehran, Iran.

Methods: All patients (less than 18 years old) undergoing Percutaneous Nephrolithotomy at our referral medical center, were reviewed in this cross-sectional study. All the demographics, surgical data and post-operative information were obtained to identify the stone free rates and complications.

Results: In a total, 119(56.4%) cases of 211 patients who underwent Percutaneous Nephrolithotomy in our study were male and 92(43.6%) cases were female. The mean age of participants was 137.15±60.11 months (range: 9-204). The most common presenting symptom was pain (62.6%). The mean stone burden was 23.5 ± 9.68mm and the mean operative time was 109.95±37.1 min. Overall, stone clearance rate was 73.9% after single PNL. Among those patients who had renal malformation, the stone free rate was (13/19) 68.4% for PCNL. The postoperative complication rate was 5/47 (10.6%) during all procedures and there were no major operative or postoperative complications.

Conclusions: According to the findings, pediatric PCNL with the acceptable stone free rates could be considered as a safe and effective procedure among children with complex stones and renal malformation.

Abstract
Background: Diabetes mellitus, type 1 (T1DM) and celiac disease (CD) are both immune-mediated. The mean rate of clinical overlap is 8%. The aim of this study was to discover the frequency of CD in children with type 1 diabetes in Mazandaran province.
Methods: This retrospective descriptive study was performed in the pediatric endocrinology referral center, in Sari from 2012 to 2014. We screened all individuals aged between six months and 18 years with diabetes diagnosis after ketoacidosis, positive anti-GAD 65 antibodies, and insulin therapy. Patients with a positive tissue Transglutaminase Immunoglobulin A (tTG-IgA) antibodies test underwent endoscopic biopsy. Categorical data were tested using chi-square and quantitative data with independent sample T-test in SPSS. Date reported with 95% confidence interval. P<0.05 was considered statically significant.
Results: Of the 119 children enrolled, six cases (5%) were positive for tTG-IgA antibodies and all of them were boys (P=0.013). Histopathologically, CD was confirmed in 5 persons (4.2%). The mean age of seropositive patients was 10.3±3.3 years. History of DKA was mostly negative (83.3%) in them. The mean breastfeeding duration was 21±3.2 months, and only one had started formula after 12 months of birth.
Conclusions: The results of the current study showed that the frequency of CD in T1DM children in north of Iran was similar to that other countries but lower than that in previous reports of Iran. The periodic screening test for CD in this high-risk group is necessary to diagnose the asymptomatic disease and prevent its complications.
