Background: The widespread use of abdominal ultrasonography in children documented increased detection rate of gallstones. The aim of this study was to assess the possible risk factors of gallstones and to detect the complication rate and outcome of the disease in Egyptian infants and children from a hepatologist perspective. This prospective study included 35 cases, with ultrasound-detected gallstones, who presented to the Pediatric Hepatology Unit from July 2015 to October 2017. All patients were initially evaluated by full history, general and abdominal examination, laboratory assessment, and ultrasound findings to detect possible risk factors of gallstones. Management approach was individualized for each patient according to his/her condition, and the patients were followed up at 3 months interval. Results: The patients' ages ranged from 3.5 months up to 17 years. The median age of gallstone detection was 2 years. Gallstones were symptomatic in 62.9% with abdominal pain in 51.4%. Complications in the form of choledocholithiasis were detected in 7 patients (20%). Laparoscopic cholecystectomy was done for 7 patients while conservative management was applied for 24 patients. Complete resolution occurred in 8.3% and partial resolution in 33.3%. Chronic hemolytic anemia was the most commonly identified risk factor for gallstones. Patients needed surgical intervention had significant higher serum cholesterol and LDL levels (P = 0.006 and P = 0.002 respectively). Conclusion: Risk factors for gallstones could be identified in most of pediatric cases. Symptomatic presentation is common among the pediatric population. Conservative management is recommended for asymptomatic cases of gallstones in children. Laparoscopic cholecystectomy is a safe and recommended procedure for complicated and symptomatic cases of gallstones.

Bronchopulmonary dysplasia (BPD) is a common complication of prematurity with a multifactorial etiology, influenced by both genetic susceptibility and environmental factors on the immature lung. Fibroblast growth factor receptor-3 and -4 (FGFR-3 and FGFR-4) are abundantly expressed in both the epithelium and mesenchyme in the developing mammalian lung. FGFR-4 may play a role in developing BPD as it is associated with airway inflammation and remodeling; studies showed a link between BPD and a polymorphism in the FGFR-4 gene. The aim of this study was to study the significance of FGFR-4 in developing BPD and to investigate the correlation between its serum level and its genetic polymorphism in relation to development of BPD in preterms. This case–control study was performed on 80 preterm neonates (<32 weeks) divided into two groups: group I included 50 preterms with respiratory distress syndrome (RDS) who developed BPD and group II included 30 preterms with RDS only. The mean serum level of FGFR-4 was significantly lower in group I than in group II (p-value < 0.05). There was no significant correlation between the serum levels of FGFR-4 and the degree of severity of BPD. Allele variation in the FGFR-4 gene was similar in both groups. The serum level of FGFR-4 was significantly lower in preterms with BPD, although the gene polymorphism was not significantly different in the studied groups.
