Evaluation of children with nutritional rickets.

AIM: To evaluate the clinical findings, risk factors, therapy and outcome in 946 children with nutritional rickets. PATIENTS AND METHODS: This retrospective study included a review of medical records of patients with nutritional rickets between March 2004 and 2009. Patients who displayed both the biochemical inclusion criteria and the clinical signs/symptoms or radiological signs of rickets were included in the study. RESULTS: The present study included 946 patients aged between 4 months and 15 years. Distribution of the cases showed a density between December and May. The age at diagnosis, showed two peaks and most of the patients were in the age range 0-23 months and 12.0-15 years. In infants and young children, most of the patients had been admitted to the hospital due to infectious diseases. In older children, short stature and obesity were the most common complaints. CONCLUSION: Children aged between 0-23 months and 12.0-15 years were under most risk for nutritional rickets, especially in winter and spring and vitamin D should be given to them as supplementation dose.

Evaluation of oxidant and antioxidant status in infants with hyperbilirubinemia and kernicterus.

OBJECTIVE: The objective of the present study was to determine oxidant and antioxidant status in infants with hyperbilirubinemia and/or kernicterus and to find whether there is a relationship between bilirubin level and oxidant/antioxidant status. PATIENTS: The study includes 69 full-term newborns (neonates with hyperbilirubinemia needing phototherapy [Group 1, n = 36] and neonates with kernicterus [Group 2, n = 33]) and 25 age-matched healthy newborn. RESULTS: Plasma total antioxidant capacity (TAC) and serum total oxidant status (TOS) were significantly higher in Groups 1 and 2 than the control group. There was a significant difference between Group 1 and control cases for malondialdehyde (MDA; p < 0.001). Total free sulfhydryl group (TTHI) values were significantly elevated in Group 1 compared to Group 2 and control cases. Correlation analysis showed that the correlation between total bilirubin (TB) and TAC, TOS, MDA and oxidative stress index may be expressed by a quadratic curve. After phototherapy, a statistically significant increase in nitrite level was observed. CONCLUSION: We demonstrated that the relationship between serum TB and antioxidants and oxidative stress could be expressed by a quadratic correlation curve.

Severe hypernatremia in newborns due to salting.

The aim of this study was to evaluate the etiology, clinical, and laboratory findings and prognostic features of life-threatening hypernatremic newborns secondary to salting. Ten severely hypernatremic newborns (four females) with a mean age of 6.5 +/- 2.6 days were followed up. Nine of them were full term, and one was preterm. It was noticeable that 60% of them were small for gestational age. In the laboratory investigation, five uremias were detected. It was interesting to find in the etiologic history that 40% of the patients had been salted just after birth. Twenty percent of them had also hyperbilirubinemia and kernicterus, 20% had neonatal convulsion, and 50% had dehydration. Two of the hypernatremic newborns died during the study; the others were followed up. One case had spasticity and developmental disability at the 3rd month, and another one had developmental disability at the 6th month of ages. As a conclusion, although salting of newborns is not so frequent, it could be seen in rural places of our country, and this may be one of the reasons for serious hypernatremia in newborns whose skin integrity have not been formed completely. These cases should be treated carefully.
