In computer technology, computer devices are susceptible to EMI because electromagnetic fields are a byproduct of passing electricity through a wire. Data lines that have not been properly shielded are susceptible to data corruption by EMI.
Quinine has been used for the treatment of malaria and associated febrile states, leg cramps caused by vascular spasm, internal hemorrhoids, varicose veins, and pleural cavities after thoracoplasty.
Quinidine has not been widely studied in children; however, it is used in children to treat abnormal heart rhythms and to treat malaria. Children may be able to take higher doses than adults and may have fewer side effects (such as vomiting, loss of appetite, and diarrhea) than adults.
