The risk factors of recurrent ischemic stroke / 영남의대학술지

To eveluate the risk factors which are related to recurrence of ischemic stroke, we selected subjects who were admitted to YNUH due to recurrent stroke and compared their risk factors with non-recurred group- who suffered from single ischemic stroke. In the subjects, 55 of them are men and 22 were women and in the non-recurred groups, 84 of them were men and 40 were women, Subject's age ranged from 29 to 86 years(Mean 62. 5years), and non-recurred group's age ranged from 27 to 90 years(Mean 60.7years), Peak incidence of ischemic stroke is in the 7th decade in both groups. Age and sex are not statistically significant for recurrence of ischemic stroke. The patient's history of diabetes mellitus, myocardial infarction, atrial fibrillation, transient attack and type or site of ischemic stroke had no significant effect statistically on the recurrent ischemic stroke. However, when the patient had previous history of hypertension or systolic blood pressure more than 160mmHg and diastolic more than 95mmHg, there was substantial difference (P<0.05) between the two group in the recurrence of ischemic stroke. According to the above results, hypertension is most likely significang risk factor of the recurrence of ischemic stroke within 2yeats after initial one. Therefore, adequate treatment of the hypertension is impertant for the prevention of ischemic stroke. Further study is required for searching other risk factors.

A Case Report of Cerebral Embolism from a Left Atrial Myxoma

Transient ischemic attacks or embolic strokes caused by the cardiac myxoma are very rare in its freguency. To detect cardiac myxoma, as a source of cerebral embolism originating from the heart, has a great significance because of the occurrence and recurrence of the possible stroke can be prevented by surgical procedure. We present a patient who showed typical clinical symptoms and signs of the left atrial myxoma which was subsequently diagnosed by 2-dimensional real time echocardiography and confirmed by sugery. Following the successful removal of the left atrial myxoma, now, the patient is in stable neurological condition.

A Case Report of Facial Diplegia Associated with Acute Viral Hepatitis type B

The Neuropsychiatric complications in acute viral hepatitis are uncommon. Despite the wide spread occurrence of this disease. Various complications of central and peripheral nervous involvement may arise during the course of viral hepatitis. Encephalitis, meningitis, neuritis, myelitis and mental disturbances such as depression, euphoria and insomnia complicating viral hepatitis has been reported several literatures. Also, bilateral facial nerve palsy is seen very infrequently in clinical practice and has an annual incidence of approximately 0.01% per total facial nerve palsy. The isolated cranial nerve palsy, especially facial nerve. Complicated by viral hepatitis has been suggested very rarely. This combination of bilateral facial nerve palsy and viral hepatitis B seems to be two phases of same disease. However, there were no such reports in Korea until now. Therefore, We present a case of bilateral peipheral facial nerve palsy associated with acute viral hepatitis type B.
