RESUMEN
Objective To investigate the clinical manifestations of nodo-paranodopathy(NPP)with anti-neurofascin 186(NF186)antibody positive.Methods The clinical data of a NPP patient with cranial nerve damage caused by anti-NF186 antibody positive was retrospectively analyzed.Results The patient was a 70-year-old male with sudden speech disorder and dysphagia one month ago.Glucocorticoid therapy was discontinued after improvement.The patient's speech,swallowing,chewing,bristling,turning and head-up movements were laborious and progressively aggravated 5 days ago.The EMG examination of the limbs was normal,and the serum and CSF anti-NF186 antibody were positive.The curative effect of glucocorticoid treatment was not obvious,and the symptoms were significantly improved after plasma exchange treatment.Conclusions Anti-NF186 antibody-positive NPP has late onset age,severe illness and accompanied with cranial nerves damage.Conventional hormone therapy is not effective,but plasma exchange therapy is effective.
RESUMEN
Objective:To investigate the clinical manifestations, risk factors and outcomes of patients with acute cingulate cortex (CC) infarction.Methods:Patients with acute CC infarction admitted to the Department of Neurology, the First Affiliated Hospital of Nanjing Medical University from December 2019 to April 2022 were enrolled retrospectively. According to the location of infarction, they were divided into anterior cingulate cortex (ACC) infarction group and posterior cingulate cortex (PCC) infarction group. The clinical manifestations, stroke risk factors, imaging examination and National Institutes of Health Stroke Scale (NIHSS) score of the patients were analyzed. At one month after onset, the modified Rankin Scale was used to evaluate the short-term outcome.Results:A total of 21 patients with acute CC infarction were enrolled, including 12 males (57.14%), aged 67.14±12.36 years (range, 45-89 years). There were 16 patients (76.19%) with ACC infarction, including 13 (81.25%) unilateral CC infarction. The clinical manifestations were mainly apathy, decreased concentration, and executive dysfunction. There were 5 patients (23.81%) with PCC infarction, all with unilateral onset, mainly manifested as memory loss and visual space disorder. Among the 21 patients, 18 (85.71%) had ≥2 vascular risk factors, and 13 patients (61.90%) had ≥3 vascular risk factors, of which hypertension was most common (90.48%); 19 (90.48%) were caused by atherosclerosis, and 2 (9.52%) were caused by cardiogenic embolism. After treatment, the symptoms of both groups were improved significantly, and there was statistical difference in the NIHSS score before and after treatment ( Z=4.07, P<0.01). During the follow-up, 16 patients (76.19%) had a good outcome, 5 (23.81%) had a poor outcome and no death occurred. Conclusions:ACC and PCC infarction mainly showed different forms of cognitive impairment. If the diagnosis and treatment are timely, the overall outcome of CC infarction is good.
