Abstract
Seizures are the most common neurological condition in dogs. Magnetic resonance imaging (MRI) is one of the most reliable diagnostic tool for neurological symptoms such as seizures. Objectives: To identify the proportion of neurological disorders and clinical responses to antiepileptic medical treatment in small-breed dogs in Jeju that underwent brain MRI. The medical records and MRI images (MAGNETOM Sempra 1.5T, Siemens, Germany) of 70 small-breed dogs referred to Jeju National University between September 2021 and April 2023 were retrospectively evaluated. Records describing the prescribed antiepileptic drugs including phenobarbital, levetiracetam, gabapentin, zonisamide, and diazepam were also evaluated. The proportions of neurological disorders diagnosed using brain MRI were as follows: idiopathic epilepsy (IE) in 22 dogs (31.4%), meningoencephalitis of unknown origin (MUO) in 14 dogs (20.0%), tumors in 8 dogs (11.4%), hydrocephalus in 5 dogs (7.2%), and others in 21 dogs (30.0%). For dogs that lasted treatment over 30 days (26 dogs), we evaluated the initial clinical response to antiepileptic drugs (AEDs). Additionally, 17/26 dogs (65.4%) treated with AED showed a complete response, 6/26 dogs (23.1%) showed a partial response, and 3/26 dogs (11.5%) showed no response. For dogs that were diagnosed with MUO or IE (36 dogs), we evaluated 365-day survival rate. Notably, 8/36 dogs (22.2%) with MUO or IE died within 365 days of presentation, 24/36 dogs (66.7%) survived beyond 365 days or were alive during the research period, and 4/36 dogs (11.1%) were lost to follow-up. Before 2021, patients with neurological symptoms in Jeju were unable to receive MRI. However, since September 2021, patients in Jeju underwent MRI imaging. This is the first retrospective study for dogs performed brain MRI in Jeju. |간질은 개의 가장 흔한 신경학적 문제 중 하나이다. 한편, 자기 공명 영상은 간질 을 포함한 신경 증상을 보이는 환자를 진단하는 데 가장 신뢰되는 도구 중 하나 이다. 본 연구의 목적은 제주도의 간질증상 소형견 중에서 뇌 자기공명영상을 촬 영 후 각 질병 비율을 확인하고 항경련제 치료에 대한 임상 반응을 평가하는 것 이다. 2021년 9월부터 2023년 4월까지 제주대학교 동물병원을 방문한 70마리의 소형견의 의료 기록 및 자기공명영상 이미지를 후향적으로 수집하였다. 간질 관 리를 위해 페노바비탈, 레베티라세탐, 가바펜틴, 조니사마이드 또는 디아제팜과 같은 항경련제가 처방되었다. 뇌 자기공명영상으로 진단된 질병은 특발성 간질 22마리 (31.4%), 원인불명의 뇌수막염 14마리 (20.0%), 종양 8마리 (11.4%), 수 두증 5마리 (7.2%), 기타 21마리 (30.0%) 였다. 간질 증상으로 30일 이상 치료를 시작한 개 26마리 중 17마리 (65.4%)가 완전한 치료반응을 보였다. 26마리 중 6 마리 (23.1%)는 부분적 치료반응을 나타내었고, 26마리 중 3마리 (11.5%)는 치료 반응이 나타나지 않았다. 또한 원인불명의 뇌수막염 또는 특발성 간질로 진단된 개 36마리 중에서 365일 생존률을 평가하였다. 36마리 중 8마리 (22.2%)가 365일 이내에 사망했고, 36마리 중 24마리 (66.7%)가 365일을 초과하여 생존했거나 연구기간 동안 생존했으며, 36마리 중 4마리 (11.1%)는 추적이 소실되었다. 2021 년 이전에는 제주에서 신경 증상이 있는 환자들이 자기공명영상을 촬영하지 못한 상황이었으나 2021년 9월부터는 제주의 환자들이 자기공명영상 촬영을 시작하게 되었다. 이는 제주지역에서 뇌 자기공명영상 촬영한 개를 대상으로 한 최초의 후향적 연구이다.
