Abstract
ObjectivesHot water epilepsy (HWE) is a type of epilepsy that primarily affects children. This study was aimed to evaluate the clinical, electroencephalogram (EEG), neuroimaging findings, and treatment options in children with HWE. MethodsThe medical records of 24 patients who had HWE were evaluated retrospectively. ResultsThere were 2767 patients diagnosed with epilepsy during the seven-year period, and 0.86% of the patients had HWE. The median age of the patients was three (range 1.2-7 years), with a male predominance (male/female ratio: 7.1). Six patients (25%) had HWE with spontaneous seizures (HWESS) and 18 patients (75%) had HWE alone (HWEA). 11 patients had focal onset seizures, 13 patients had generalized onset seizures. EEG abnormalities were found in 7 patients (29.2%). Three patients (12.5%) had nonspecific MRI findings. Developmental abnormalities (autism spectrum disorder, learning disability and speech disturbance.) were detected in 8 patients (33.3%). Only one patient's (4.2%) seizure could be controlled by changing bathroom habits. Twenty-three patients (95.8%) were given antiepileptic drugs. 18 of 24 patients had come for follow-up visits for two years, nine of them used monotherapy and seizures did not recur. The treatment response was 55.5%. Oxcarbazepine (8 patients, 33.3%) and valproic acid (7 patients, 29.2%) were the most chosen two drugs for HWE. The genetic tests performed were not accepted relevant to the patients' clinical conditions and epilepsy. ConclusionThe frequency of the HWE was not as high in the literature. Male predominance, EEG abnormalities may be seen. Changing bath room habits did not improve the treatment as a first line management, all the patients except one used antiepileptic drug treatment. Until now, there has been no study in Turkey showing the frequency of HWE exclusively in children.
