Objectives:

To see the status of Zinc in CSF of children with febrile convulsion and to compare this with that of control.

Methods:

Place of study : Department of Paediatrics, Dhaka Medical College Hospital

: Atomic Energy Commission, Dhaka, Bangladesh

Period of study: From July 1999 to December 1999

Type of study : Prospective case control study

Sample size     : 72  ( Case: 42 , Control: 30)

Age & Sex      : 06 months to 6 years and of both sex

Working Definition:

Febrile convulsion: Fever with single generalized convulsion persisting less than 15 minutes without features of intracranial infection.

 

Inclusion criteria of study cases: Children with febrile convulsion

Inclusion criteria of control cases: Febrile children without convulsion

Exclusion criteria: Cases beyond the specified age range, who had clinical and CSF features of CNS infection and who were taking zinc for therapeutic purposes.

After clinical evaluation, CSF was collected in a specially prepared zinc free plastic container. Zinc level was estimated by Atomic Absorption Spectrophotometry method. Statistical analyses of the results were done by SPSS+ (version 7.5) and Mann Whiteney U-test.

Results:

The mean zinc level in CSF in the study samples was 40.19 microgram /L and that in control samples was 74.98 microgram/L. The difference was statistically significant

( p<0.001). No relationship was found between CSF zinc status with age, sex, degree & duration of fever.

Conclusion:

The study shows a close relation between low levels of zinc in CSF and febrile convulsion. Further interventional studies are required to confirm the result of low zinc in CSF in febrile convulsion.
