These results indicate that the TQ produces a protective mechanism against VCM-induced nephrotoxicity and suggest a role of oxidative stress in pathogenesis.

Current detailed information about the causes, management, and clinical course of acute childhood poisonings in Turkey is scarce. Therefore, we have conducted a descriptive study of children presenting with acute poisoning to the pediatric emergency department of Dicle University Hospital throughout an 8-month period. Two hundred unselected children with poisoning were evaluated in terms of clinical, epidemiological and socioeconomic aspects. The mean age of patients was 5.7 ± 4.0 years. The majority of the patients ( n = 108, 54%) were aged from 13 months to 4 years ( P < 0.05). In majority of patients (66.5%, n = 133), poisonings were accidental. Intentional poisonings accounted for 3.5% ( n = 7) and food poisoning accounted for 30% ( n = 60) of all cases. The families had more than three children in 129 (97%) of accidentally poisoned and in seven (100%) of intentionally poisoned patients, six were girls and one was a boy. The parents of most patients were uneducated. Furthermore, more than two third of families had low level of income. In all, 171 patients (85.5%) were discharged after an observation period of 24 h. Four patients died. In conclusion, factors such as low educational level of parents, presence of more than three children in the family, and low income increase the incidence of childhood poisonings. The low educational level of girls increases the incidence of intentional poisoning.

Probiotics have been successfully used for the treatment of acute diarrhea in children and this effect depends on the strains and dose. The aim of this study was to assess the effect of a synbiotic mixture on the duration of diarrhea and the length of hospital stay in children with acute watery diarrhea. This is a prospective randomized, multicenter single blinded clinical trial in hospitalized children with acute watery diarrhea. All children were treated with conventional hydration therapy with or without a daily dose of a synbiotic (2.5 × 10(9) CFU live bacteria including Lactobacillus acidophilus, Lactobacillus rhamnosus, Bifidobacterium bifidum, Bifidobacterium longum, Enterococcus faecium, and 625 mg fructooligosaccharide) for 5 days. The primary endpoint was duration of diarrhea and duration of hospitalization was the secondary endpoint. Among 209 eligible children, 113 received the synbiotic mixture and 96 served as a control. The duration of diarrhea was significantly shorter (∼36 h) in children receiving the synbiotic group than the controls (77.9 ± 30.5 vs. 114.6 ± 37.4 h, p < 0.0001). The duration of hospitalization was shorter in children receiving the synbiotic group (4.94 ± 1.7 vs. 5.77 ± 1.97 days, p = 0.002). The effect of synbiotic mixture on diarrhea started after 24th hours and stool frequency significantly decreased after 24th and 48th hours. The percentage of diarrhea-free children is significantly higher in synbiotic group at 48th and 72nd hours of synbiotic group. In conclusion, this study showed a reduction in diarrhea duration by approximately 36 h and a reduction in the duration of hospitalization with approximately 1 day in children with acute diarrhea with this synbiotic mixture.

Reactive oxygen species (ROS) are reported to play a role in inducing the proteinuria of nephrotic syndrome (NS). This study investigated paraoxonase (PON), total antioxidant response (TAR), and oxidant total peroxide together with serum proteins and lipoproteins in children with steroid-sensitive NS. The study included 40 children with steroid-sensitive NS (21 with acute-period NS in group I, 19 nonproteinuric while receiving steroids in group II) and 22 sex- and age-matched formerly nephrotic children in remission weaned from steroids (group III). The following parameters were determined: total peroxide, oxidative stress index (OSI), PON and TAR. Serum proteins and lipoproteins were also determined. Patients in the active phase of NS had significantly lower PON and TAR levels and higher OSI and total peroxide values than those in full remission; no differences were found in PON, TAR, or OSI values of groups I and II. Significant correlations were found between PON, TAR, and total peroxide. Serum total protein had a significantly positive correlation with PON and negative correlation with total peroxide in acute-period NS patients. Our results demonstrate greater oxidative stress and decreased antioxidants in the active phase of steroid-sensitive NS and while patients receive steroids than during full remission. Low-dose alternate-day steroids do not seem to decrease oxidative stress even while proteinuria ceases. Despite some conflicting data increased oxidation and/or decreased antioxidant response may be related to the pathogenesis of steroid-sensitive NS.
