Comparative Efficacy of Ferrous, Ferric and Liposomal Iron Preparations for Prophylaxis in Infants.

OBJECTIVES: This study aimed to assess the efficacy of different oral iron preparations prescribed for prevention of iron deficiency anemia in healthy infants. METHODS: This retrospective study enrolled infants aged between 6 and 12 months who were initiated on iron prophylaxis at four months of age. Enrolled children consistently used specific iron preparations (ferrous, ferric or liposomal iron) and had their complete blood counts and serum ferritin levels assessed within the 6-12 month timeframe. Blood values and iron prophylaxis type (ferrous (Fe+2), ferric (Fe+3), liposomal iron) were recorded. Chi-square test was used to compare the hemoglobin and ferritin levels levels between groups. Univariate and multivariate regression analyses assessed the risk of anemia. RESULTS: The study included 371 children (ferrous sulphate - 60, iron hydroxide-polymaltose complex - 137 and liposomal ferric pyrophosphate - 174) with a mean (SD) age 9.1 (1.3) mo. Iron deficiency in different groups were: liposomal iron (46.0%), ferric iron (44.5%), and ferrous iron (5.0%). Mean (SD) serum ferritin levels (µg/L) were higher in the ferrous group [30.1 (10.8)] compared to infants receiving ferric [17.6 (14.50)] and liposomal iron [15.4 (12.1)] (P < 0.001). Mean (SD) hemoglobin levels (g/dL) were significantly higher in the ferrous group [12.4 (0.8)] compared to ferric [11.9 (1.1)] and liposomal iron group [12.0 (1.1)]; P =0.008. Multiple regression analysis showed that ferrous group was associated with a lower risk of iron deficiency [OR (95% CI) 0.04 (0.01-0.15), P < 0.001]. CONCLUSION: A particular type of airway anomaly may have a characteristic graphic pattern in TBFVL and TBFVL pattern may indicate improvement in airway anomalies in follow-up.

Compatibility levels between blood gas analysis and central laboratory hemoglobin and electrolyte tests in pediatric patients: A single-center experience.

INTRODUCTION: We aimed to evaluate the interchangeability of sodium, potassium, hemoglobin, and hematocrit measurement between the blood gas analyzers and laboratory automatic analyzers results. METHODS: This was a retrospective cross-sectional study. The results of 1927 paired samples analyzed simultaneously with the blood gas analyzer and the laboratory automatic analyzer were compared. The Bland-Altman and Cohen's kappa statistic detected the agreement between the two analyses. RESULTS: The limits of agreement (±1.96 standard deviation of the mean difference) were -11.1 to 20.3 for sodium, -1.9 to 0.5 for potassium, -16.1 to 12.9 for hematocrit, and -5.0 to 4.0 for hemoglobin. Agreement between the two analyses was not acceptable within the defined clinically acceptable limits. In addition, none of the kappa values were higher than 0.60, which highlights the lack of agreement between the two analyzers. CONCLUSION: The blood gas analyzers and laboratory automatic analyzers results cannot be used interchangeably.

The association of vitamin D deficiency with hemogram-derived inflammatory biomarkers in children.

BACKGROUND AND AIMS: One of the extraosseous effects of vitamin D is that it is a potent modulator of inflammatory processes. Many studies have demonstrated the inverse association between vitamin D and inflammation. Therefore, we hypothesize that vitamin D deficiency may affect the inflammatory markers derived from hemogram parameters [neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR), platelet distribution width (PDW), red blood cell distribution width (RDW)] in healthy children. METHODS AND RESULTS: We conducted a retrospective study on healthy children. From 2015 to 2020, 16,321 children with simultaneous vitamin D and hemogram measurements were identified from electronic records. Participants were divided into 2 groups according to whether they had vitamin D deficiency or not. The relationship between vitamin D status and the levels of inflammatory markers was analyzed. All inflammatory markers showed statistically significant differences between vitamin D status (p < 0.001 for all). Vitamin D levels were significantly negatively correlated with NLR (r = -0.285), PLR (r = -0.257), PDW (r = -0.181), and positively correlated with LMR (r = 0.218), and RDW (r = 0.057). In logistic regression analysis, age (OR = 1.15, 95% CI: 1.14-1.16), gender (OR = 1.66, 95% CI: 1.54-1.78), LMR (OR = 0.96, 95% CI: 0.95-0.98), PLR (OR = 1.003, 95% CI: 1.001-1.004), and RDW (OR = 1.10, 95%CI: 1.07-1.13) were found to be independent predictors for vitamin D deficiency. CONCLUSIONS: Statistically significant differences were detected between vitamin D status and inflammatory parameters. However, the difference between the median values of vitamin D groups was very small and the degree of correlation was very weak. Therefore, the clinical significance of the difference should be questioned.

New Entity of Skull Lesions due to Birth Trauma: Kanat (Wing) Fractures.

AIM: To discuss a special type of skull lesion detected after delivery. We reviewed our experience on scalp swelling in term neonates to further investigate the relationship between cranial injuries and labor process. MATERIAL AND METHODS: A total of 55 newborns with scalp swellings were assessed with medical records retrospectively between January 2007-July 2017. A radiologist and a pediatric neurosurgeon re-analyzed all skull X-ray images via picture archiving and communication system of the hospital. RESULTS: A special type of skull fracture, called Kanat (wing) fracture, was detected. The fractures appeared unique, were located in the midline parietal bone, and were difficult to detect by X-ray. Kanat fractures accounted for 12.7% of the 55 cases (n=7). Patients without (group-1) and patients with (group-2) Kanat fractures were compared based on the head circumference of the newborns (p=0.881), fetal birth weight (p=0.20), maternal age (p=0.04), duration of second stage of labor (p=0.217), maternal body mass index (p=0.278), total labor time (p=0.922) and parity (p=0.375). No statistically significant difference between the two groups was determined for the compared parameters. CONCLUSION: The present study is the first research describing and discussing the possible effects of maternal, fetal and delivery characteristics on Kanat fractures. Designing clinical and experimental researches to enhance awareness and acknowledgement of skull injuries and labor process could improve the clinical outcome of the newborns.
