OBJECTIVE
To retrospectively evaluate the epidemic characteristics of children with hypocalcemic convulsion related to nutritional rickets in the province of Kars, Turkey.
METHODS
In this study, clinical and laboratory findings of 93 infants, aged between 1-24 months, who were diagnosed as hypocalcemic convulsive resulting from nutritional rickets between January 2000 and June 2005 in Kars Maternity and Child Hospital, were investigated. The data of the cases with hypocalcemic convulsive rickets were collected from the hospital archive file.
RESULTS
The mean and median ages of the cases were 8.93 and 6 (1-24) months, and 66 (71%) were male. Most of the patients were admitted to hospital in February and March, whereas 46% were admitted in winter, 44% in spring, 8% in autumn, and 2% in summertime. Serum calcium levels of all cases were low (mean: 5.4 +/- 0.84 mg/dl) and serum alkaline phosphate levels were high (mean: 1286 +/- 528 IU/L), while serum phosphorus levels were low in 19 (20.4%), high in 8 (8.6%), and normal in 66 (71%) patients.
CONCLUSIONS
While evaluating the causes of convulsion, hypocalcemic convulsion related to nutritional rickets should be considered among the causes as well as age, gender, and season of the year, and diagnosis, and treatment should be initiated without delay. In addition, serum phosphorus level should also be questioned in the diagnosis of nutritional rickets.
