A one-and-a-half-year-old child is experiencing persistent anal itching, which has been ongoing for over a month. Is it appropriate to use mebendazole tablets for treatment? Does over a month indicate a severe parasitic infection situation?

Children grinding their teeth at night may be related to parasitic infections or emotional restlessness and fatigue.

The main causes of bedwetting in children may include enuresis, delayed bladder development, urinary tract infections, pinworm disease, or spinal defects. It is recommended that parents take their children to a regular hospital for examination to confirm and treat the relevant diseases.
