Aim To prevent possible chronic kidney diseases in healthy school- age children by screening for hematuria and proteinuria using a urine strip. Methods The incidence of hematuria and proteinuria was determined in 1848 healthy school-age children aged 7 to 14 years by urine screening in the eastern region of Turkey in 2008. Cases with persistent hematuria and/or proteinuria were referred to a pediatric nephrologist, and further examinations were carried out. Results Isolated hematuria, isolated proteinuria, and combined hematuria-proteinuria were found in 92 (4.9%), 16 (0.8%) and 10 (0.5%) patients, respectively. In addition, 11.9% (11/92) of cases of isolated hematuria and 40% (4/10) of cases of combined hematuria- proteinuria were observed to have persisted. Persistent hematuria and persistent hematuria-proteinuria were found in 11 (0.5%) and 4 (0.2%) patients, respectively. In these cases, underlying causes were found: renal stone disease, hypercalciuria, urinary tract infection, vesicoureteral relux, atrophic kidney, and IgA nephropathy. Conclusion According to this study, cases with persistent hematuria should be examined especially in terms of renal stones, hypercalciuria, and urinary tract infection.
Evaluation of 900 and 1800 Mhz Radiofrequency Radiation Emitted From Mobile Phones on Pregnant Women
(University of Dicle, 2021) Bektas, H.; Dasdag, S.; Bektas, M.S.
The purpose of the present study was to investigate effects of radiofrequency radiation (RFR) emitted from mobile phones (MOBPHs) on pregnant women and fetuses (PW&F). Correlationsbetween effects occurring and MOBPH usage duration (MOBPH-UD) and frequency of the RFRemitted were evaluated. The study comprised pregnant women divided into 4 groups: (control) non-MOBPH users; 1) MOBPH-UD: 2–15 min/day; 2) MOBPH-UD: 15–60 min/day; and 3) MOBPH-UD:>60 min/day.We investigated were the effects of RFR exposure on protein carbonyl (PCO), malondialdehyde(MDA), total oxidant and antioxidant status (TOS, TAS), 8-hydroxy-2-deoxyguanosine (8-OHDG),and DNA single-strand breaks (SSBs) in the cord blood and placenta of pregnant women who usedMOBPHs for different durations. A positive correlation existed between the MOBPH-UD andharmful effects examined. Additionally, the alkaline comet assay for determination of DNA SBsshowed that using MOBPHs caused DNA SSBs.The results indicated that 900 and 1800 MHz RFR had great potential to affect PW&F.However, a correlation existed between the MOBPH-UD and harmful effects. In conclusion, theresults suggested that exposure to 900 and 1800 MHz RFR from MOBPHs usage could potentiallyaffect PW&F © 2021, Journal of International Dental and Medical Research.

Infantile Digital Fibromatosis (Inclusion Body Fibromatosis) Observed in a Baby Without Finger Involvement
(2013) Kaya, A.; Yuca, S.A.; Karaman, K.; Erten, R.; Dogan, M.; Bektas, M.S.; Ustyol, L.
A 9-day-old male baby was hospitalized after his birth due to some swells under the skin. The hard consistency nodules observed under the skin all over the body of the patient were of different size, and presented lesions, among which the biggest was 1 × 1 cm. No lesions were observed on the fingers. By superficial ultrasonography, multiple isoechoic hypoechoic lesions were observed among the muscle plan. In thoracolumbar magnetic resonance imaging, multiple massif lesions retaining peripheral contrast (the biggest was 1.7 × 1.4 cm large) had been observed under the skin muscle plans, between the muscles of the extremities. The biopsy was positive for smooth muscle actin, but negative for desmin, S100, and CD34. These findings were diagnosed as infantile digital fibromatosis (IDF) (inclusion body fibromatosis). The case was presented with an objective to illustrate and remind that IDF can be observed in babies without finger involvement.
