Depression, anxiety, ADHD and smoking addiction are associated with PIU in adolescent students. Preventive public health policies targeting the psychological wellbeing of young people are needed.

Objective: To evaluate the accuracy of urine sample collection methods among children suspected of having urinary tract infections. Subjects and Methods: Four methods for urine sample collection were evaluated in 1,067 children aged 0–16 years with suspected urinary tract infections over 2 months at Dr. Sami Ulus Children’s Hospital. Within 30 min of collection, all specimens were sent to the laboratory, refrigerated and processed according to standard hospital microbiological procedures. Urine samples were analyzed using routine culture techniques. Results: At initial sending of the urine culture, 617 (57.8%) had negative culture results, 145 (13.6%) had positive culture results, and 305 (28.6%) had evidence of bacterial contamination. Clean catch specimens showed a contamination rate of 14.3% and urethral catheterization specimens showed a similar contamination rate (14.3%). However, urethral catheterization was preferred in only a small number of cases (n = 7). Suprapubic aspiration was also used in a small number of cases (n: 11) and the contamination rate for suprapubic aspiration was 9.1% (n: 1/11). The contamination rate for sterile urine bag was 43.9%, significantly higher than the other methods (p < 0.001). Conclusion: Suprapubic aspiration showed the lowest contamination rate and sterile urine bag showed the highest contamination rate among 4 methods of urine sample collection. Contaminated specimens, needed to be repeated and this procedure increased the cost of urine culture. In conclusion, measures should be taken to reduce the contamination rate in our center. This is an area where further investigation is required.

Socioeconomic risk factors were observed to be as important as biological risk factors in the development of children aged 3 months-5 years.

Parental education about 'fever in childhood' in our population may positively effect parental knowledge and approach to fever. However, parental education may not be effective in removing parental fear of fever in our population.

Genetic analyses of the siblings revealed homozygosity for mutation c.736C>T on the GYS2 gene confirming the diagnosis. The third patient was found to be homozygous for c.1145G>A. GSD0 is more common than previously assumed. Recognition of the variable phenotypic spectrum of GSD0 and routine analysis of GYS2 are essential for the correct diagnosis.
