ABSTRACT
OBJECTIVE: Leukocyte contamination during blood transfusion can cause many adverse effects. Filtration can be performed either at bedside during the transfusion or as pre-storage filtration. Pre-storage filtration is superior to bedside filtration because leukocytes are removed prior to storage, thus preventing further adverse effects associated with the storage of these cells. METHODS AND MATERIALS: One hundred and six infants were randomised into two groups: pre-storage filtration (group 1, n = 53) and bedside filtration (group 2, n = 53). C-reactive protein (CRP) and interleukin-6 (IL-6) levels were analysed within 24 h prior to the transfusion and 24 h after completion of the transfusion. RESULTS: In group 1, pre-transfusion median CRP and IL-6 levels were 2·95 (0·73-10·25) mg L(-1) and 8·59 (3·45-20·55) pg L(-1) , respectively, and post-transfusion median CRP and IL-6 levels were 2·28 (0·44-12·87) mg L(-1) and 6·62 (2·18-27·87) pg L(-1) , respectively. In group 2, pre-transfusion median CRP and IL-6 levels were 1·30 (0·40-7·84) mg L(-1) and 4·40 (2-17·12) pg L(-1) , respectively, and post-transfusion median CRP and IL-6 levels were 3·50 (0·50-7·85) mg L(-1) and 8·30 (3·48-23·75) pg L(-1) , respectively. There were no differences between pre-storage and post-storage leukoreduction average IL-6 and CRP levels in either group (P > 0·05 for both). Packed red blood cell (PRBC)-related necrotizing enterocolitis was detected in one infant in group 2. CONCLUSIONS: Because leukocytes in PRBC transfusions can be associated with many undesirable effects, leukoreduction is the best choice to prevent those effects. However, this method is still controversial. We demonstrated that using pre-storage and post-storage leukoreduction methods in erythrocyte transfusions did not change CRP or IL-6 levels, which are indicators of acute-phase response.

Jarcho-Levin syndrome (JLS) is a genetic disorder characterized by defects of spine formation, abnormal fusion of the ribs at the costovertebral and costochondral junction due to abnormal vertebral and costal segmentation. There are two subtypes associated with different distribution and severity of defects in JLS. While vertebral segmentation abnormalities are frequent in spondylo-thoracic subtype costal segmentation and fusion abnormalities are frequent in spondylo-costal subtype. Neural tube defects with severe hydrocephalus are rare findings in this syndrome. Herein we report three infants with severe hydrocephalus associated with Jarcho-Levin syndrome.

Although complete blood count is routinely ordered in most upper urinary tract infections (UTI), and information regarding the patient's platelet indices is made available without added cost, the relationship between platelet count and mean platelet volume (MPV) and specific platelet responses to different infectious agents has not been extensively characterized in UTI. The objectives of this study were to examine platelet counts and platelet indices in children with culture-proven upper UTI to determine if there are organism-specific platelet responses. A retrospective analysis of data from all pediatric urine samples processed at Fatih University Medical School microbiology laboratory was undertaken for a period of two years (January 1, 2005, to December 31, 2006). Of the 200 patients with positive urine cultures, 146 (73%) were infected with gram-negative bacteria and 54 (27%) grew gram-positive bacteria. The platelet count during the episode of upper UTI and the incidence of thrombocytosis was significantly higher with the gram-positive infections than with the gram-negative infections or controls (p < 0.05). A statistically significant higher MPV was detected in the subjects with upper UTI (p < 0.05). Also, our data showed a statistically significant increase in MPV with gram-positive infections compared with the other groups (p < 0.05). In conclusion, based on the importance of the hemostatic component in the pathophysiology of infections, our findings of platelet count and MPV and predictivity of the type of the organism would suggest the usefulness of the routine measurements in children with upper UTI.

BACKGROUND: Ceftriaxone, a third generation cephalosporin, is widely used for treating infection during childhood. The kidneys eliminate approximately 33-67% of this agent, and the remainder is eliminated via the biliary system. Ceftriaxone may bind with calcium ions and form insoluble precipitate leading to biliary pseudolithiasis. The aim of this study was to assess whether ceftriaxone associated nephrolithiasis develops by the same mechanism, and whether this condition is dose related. METHODS: The study involved 51 children with various infections. Of these, 24 were hospitalized with severe infection and received 100 mg/kg/day ceftriaxone divided into two equal intravenous doses. The other 27 patients received a single daily intramuscular injection of 50 mg/kg/day. Serum and urine parameters were evaluated before and after treatment, and abdominal ultrasonographic examinations were also carried out before and after treatment. RESULTS: Serum urea, creatinine, and calcium levels were normal in all patients before and after treatment. Post-treatment ultrasound identified nephrolithiasis in four (7.8%) of the 51 subjects. The stones were all of small size (2 mm). Comparison of the groups with and without nephrolithiasis revealed no significant differences with respect to age, sex distribution, duration of treatment, or dose/route of administration of ceftriaxone. The renal stones disappeared spontaneously in three of the four cases, but were still present in one patient 7 months after ceftriaxone treatment. CONCLUSIONS: Conclusions: The study showed that children taking a 7 day course of normal or high dose ceftriaxone may develop small sized asymptomatic renal stones. The overall incidence of nephrolithiasis in this study was 7.8%.
