Urinary Stones in Neonates: Dilemma Between Urolithiasis and Nephrocalcinosis
Urinary stones are extremely rare in the neonatal population. Most of
the urinary stones in the neonate contain calcium. Nephrolithiasis in the
neonate may be as urolithiasis and/or nephrocalcinosis. The incidence
of nephrocalcinosis is not yet clear and can be differ in many researches
due to the etiology. On the other hand, the incidence of urolithiasis in
childhood is almost 10% of that in adults. Especially in the first decade, it
is more common in boys. It may occur with inherited metabolic changes
such as hypercalciuria, primary hyperoxaluria or cystinuria. Stone formation
can be effected by iatrogenic causes such as hyperalimentation (parenteral
nutrition), diuretic therapy (furosemide, acetazolamide) that is especially in
the bronchopulmonary dysplasia. The stone formation may occur due to
anatomic or functional obstructions and infections of urinary system. Most of
the urinary stones in the neonatal period are diagnosed as a nephrocalcinosis.
However there aren’t any exact differences between nephrolithiasis and
nephrocalcinosis. Some authors suggested nephrocalcinosis is the initial
step of urinary stone formation. On the other hand, the others purposed
that both of them are different pathologies. In this review, we tried to
summarized differences and similarities, in the context of urinary stones and
the nephrocalcinosis in the neonates
Distribution of monocyte chemoattractant protein-1 (MCP-1 A-2518G) and chemokine receptor (CCR2-V64.) gene variants in hyperbilirubinemic newborns
Hyperbilirubinemia is one of the most crucial syndromes, which is characterized by high levels of bilirubin, especially when it occurs in newborns. Bilirubin has cytoprotective properties with an antioxidant function and plays several major roles in the inflammation process with its members such as chemokines. The monocyte chemoattractant protein-1 (MCP-1) is a member of the C-C chemokine family and it has been associated with the inflammatory process. There are no data on the chemokine and its receptor genotypes in hyperbilirubinemic newborns to show their distribution. The aim of this study is to investigate the genotypic relationship of MCP-1 and its receptor CCR2-V64. with hyperbilirubinemia in Turkish newborns. A total of 85 newborns were included in the study: 20 infants with hyperbilirubinemia (hyperbilirubinemic group) and 65 infants without hyperbilirubinemia (non-hyperbilirubinemic group). Genotyping of MCP-1 A-2518G and CCR2-V64. gene polymorphisms were detected by PCR-RFLP, respectively. MCP-1 GG genotype in patients was higher than the controls and this genotype had 2.69 times higher risk for hyperbilirubinemic neonates (P: 0.20). The frequency of MCP-1 A-2518G G+ genotype in patients was higher than the controls (55.0% and 38.5%, respectively). The results of our preliminary study suggest that MCP-1 G+ genotype has the ability to increase the hyperbilirubinemia risk of newborns. These results should be focused on to research on a larger scale to confirm the findings
Neonatal hyperbilirubinemia and G71R mutation of the UGT1A1 gene in Turkish patients.
Objective. Nonphysiologic hyperbilirubinemia of unexplained cause is prevalent among Turkish newborns, suggesting that there might be genetic risk factors in this population. Mutation of the UGT1A1 gene, glycine to arginine at codon 71 (G71R), is related to the development of neonatal jaundice in East Asian populations but the frequency of this mutation is rare among Caucasian populations. There are insufficient data on the G71R mutation in Turkish newborns with hyperbilirubinemia. The aim of this study was to investigate the genotypic distribution of the G71R mutation and its relationship with nonphysiologic hyperbilirubinemia of unexplained cause in Turkish newborns
An alternative supplemental feeding method for preterm infants: the supplemental feeding tube device
Background/aim: The purpose of this study was to determine the effects of the supplemental feeding tube device (SFTD) and bottle methods on weight gain, transition to full breastfeeding, breastfeeding success, and duration of discharge in preterm infants. Materials and methods: This randomized controlled trial was conducted with a total of 46 preterm infants including 23 infants in study (SFTD) and control (bottle) groups. An information form, an infant follow-up form for feeding, and LATCH breastfeeding assessment instrument were used to collect the data. Results: The gestation week of the infants in the study group was 31.22 +/- 2.76, and in the control group it was 30.52 +/- 2.47. The birth weight of the infants in the study group was 1586.3 +/- 525.35 g and 1506.09 +/- 454.77 g in the control group. The daily weight gain of the infants was 24.09 +/- 15.21 g in the study group and 27.17 +/- 17.63 g in the control group. The infants in the study group (4.70 +/- 2.44 days) transitioned to full breastfeeding earlier than those in the control group (6.00 +/- 4.10 days). LATCH 2nd measurement scores were significantly higher in both groups than LATCH 1st measurement scores (p 0.05), the infants in the study group (10.22 +/- 5.20 days) were discharged earlier than those in the control group (13.48 +/- 8.78 days). Conclusion: The SFTD and bottle methods were determined to be similar in terms of daily weight gain, transition to full breastfeeding, breastfeeding success, and duration of hospitalization

Factors affecting the course of body and kidney growth in infants with urolithiasis: A critical long-term evaluation
Objective: To investigate the possible effects of dietary, patient and stone related factors on the clinical course of the stone disease as well as the body and renal growth status of the infants. Patients and Methods: A total of 50 children with an history of stone disease during infancy period were studied. Patient (anatomical abnormalities, urinary tract infection - UTI, associated morbidities), stone (obstruction, UTI and required interventions) and lastly dietary (duration of sole breast feeding, formula feeding) related factors which may affect the clinical course of the disease were all evaluated for their effects on the body and renal growth during long-term follow-up. Results: Mean age of the children was 2.40 ± 2.65 years. Our findings demonstrated that infants receiving longer period of breast feeding without formula addition seemed to have a higher rate of normal growth percentile values when compared with the other children. Again, higher frequency of UTI and stone attacks affected the growth status of the infants in a remarkable manner than the other cases. Our findings also demonstrated that thorough a close follow-up and appropriately taken measures; the possible growth retardation as well as renal growth problems could be avoided in children beginning to suffer from stone disease during infancy period. Conclusions: Duration of breast feeding, frequency of UTI, number of stone attacks and stone removal procedures are crucial factors for the clinical course of stone disease in infants that may affect the body as well as kidney growth during long-term follow-up
