In Korea, the pattern of age-specific seroprevalence of anti-HAV has changed with economic growth. The prevalence of anti-HAV in age 1~20 years declined from 60% in 1980 to 9% in 1995. As a result, this age group has a high risk for HAV infection, and actually the incidence of clinically overt hepatitis A is increasing in adolescents and young adults recently. In contrast, the prevalence of HBV carriers has been markedly decreased up to less than 1% in children because of the preventive strategies for HBV infection. The prevalence of HBsAg among Korean adults also declined from 8.0% in male and 6.1% in female in the 1980s to 7.4% in male and 3.6% in female in 1997. This article reviews recent epidemiologic changes of acute and chronic hepatitis in Korea.

We present a series of 10 Patients(Seven men and three women with an average age of 53 years) who underwent decompressive craniectomy for treatment to massive brain swelling following acute cerebral infarction. Clinical signs of cerebral herniation(anisocoria or fixed and dilated pupil, and/or hemiplegia with decerebrate righidity) were present in all patients. Computed tomography and magnetic resonance imaging showed the mass effect by cerebral edema through midline shift. All patients were treated with an extensive craniectomy and duroplasty. Among them, one recovered without neurological deficit, three were moderately disabled but functionally dependent, three remained in a persistent vegetative state and three died within 9 days after surgery(good recovery=1, moderate disability=3, persistent vegetative state=3, death=3). The results suggest that decompressive craniectomy can be an useful lifesaving procedure for massive cerebral edema following widespread hemispheric infarction.

Spinal stenosis denoting a critical reduction of the A-P diameter of spinal canal, foramina and lateral recesses can be existed in both cervical and lumbar regions. But it is relatively rare that cervical and lumbar spinal stenosis are coexisted simulataneously. The authors report a case of coexisting cervical and lumbar spinal stenosis with historical background and discussion. The patient was 49 years old male who complained intermittent neurogenic claudication, paraparesis and voiding disturbance. A successful result was obtained through one stage decompressive laminectomies in cervical and lumbar reaions.

Authors report a rare case of arteriovenous malformation associated with porencephaly in left frontal lobe of a 35 years old man. Local brain atrophy is generally ascribed to local pressure effect by the vascular malformation or to localized circulatory disturbances, so as in this case.

Seven cases of traumatic subdural hygroma are presented, with discussion of their predilection in the frontal region, clinical features and postoperative course. It is shown that hygroma can be the principal or secondary cause of the frontal lobe syndrome following head trauma. None of the cases could be well differentiated from chronic subdural hematoma by angiography and CT scan. Therefore a neurosurgical intervention, such as an osteoplastic craniotomy or a simple trephination has been employed for the diagnosis and the treatment. In the operation of the chronic subdural hygroma, the arachnoid flap of it or the membrane, if it is formed, should be widely excised. After the operation continuous drainage through a cranial hole for several days would be ideal.
