The authors describe the course of herpetic encephalitis in 52 patients aged 16 to 64 years. Five types of the initial manifestations of herpetic infection of the CNS were revealed. In 44.3% of cases the disease started from the general cerebral symptomatology and consciousness disturbance; in 13.6% it started in a brain stroke-like manner followed by the development of the comatose status; in 13.6% of cases from memory disorder and unmotivated actions; in the same percentage of cases, the disease onset was marked by the dominance of dizziness, diplopia, ataxia and central hemiplegia ; in 15.9% the disease started from pains in the stomach, loin and lower limbs. Hemispheric and pseudotumorous stem encephalitides (48.1 and 13.6% respectively) were predominant; in 25% meningoencephalitides and in the remainder, encephalomyelitis running their course in the form of disseminated encephalomyelitis (5.7%), focal myelitis (5.7%) or opticomyelitis (1.9%). The data presented attest to the pleomorphism of the clinical picture of herpetic lesions of the CNS.

We reported an autopsy case of a 14-year-old girl with cardiac myxoma, presenting sudden onset of consciousness disturbance and right hemiplegia while running in an 800 meter race. Though CT scan showed no abnormal findings, cerebral angiogram revealed an embolic stenosis of the left middle cerebral artery, and abdominal aortogram showed complete obstruction of the bilateral common iliac artery. Histological study of emboli taken from obstructed femoral arteries showed systemic embolization of the cardiac myxoma. She died three days after admission. Autopsy was performed. Myxoma tissue was not found, but its stalk was left in the left atrial septum. The brain was very edematous, and a myxoma emboli was found in the left middle cerebral artery. Systemic embolization of myxoma to spleen, kidneys, liver, pancreas, etc. was found histologically. Left atrial myxoma is a rare but potentially treatable cause of stroke, and should be included in the differential diagnosis of cerebral vascular disease, especially in young patients.

A 17-year-old boy was hospitalized with transient consciousness disturbance on extension of the neck. At seven years of age, the patient developed delayed-onset posterior circulation stroke after the door struck him a mild blow on his forehead. A computed tomography scan revealed right cerebellar infarction with unknown etiology. He had been followed up without stroke recurrence and CT change until this hospitalization. Cerebral angiography disclosed bilateral vertebral artery occlusion at the C-2 level with the well-developed muscular collateral artery bypassing the occluded left vertebral artery. A cervical X-ray showed a posterior atlanto-axial subluxation with os odontoideum. Compression of the vertebral arteries due to mild trauma aggravating an atlanto-axial subluxation may have caused the bilateral vertebral artery thrombosis resulting in occlusion, and disturbance of the muscular collateral circulation on extension of the neck may have led to the recurrence of vertebrobasilar insufficiency. This is the first report of the angiographically confirmed bilateral vertebral artery occlusion with an established etiology in childhood.

Thirty-one consecutive cases of intracerebral hemorrhage (ICH) in the elderly (over 70 years at the onset) were reported with special reference to neurological evaluations, prognosis and mortality in the acute phase. There were 11 men and 20 women with ICH, who were admitted to the Yokufukai Geriatric Hospital within 24 hours after the onset of ICH. Their ages at the onset ranged from 71 to 93 years with a mean of 81.1 years. The lesion location showed 5 cases with thalamic hemorrhage, 4 cases with putaminal hemorrhage, 6 cases with subcortical hemorrhage, 7 cases with cerebellar hemorrhage, 8 cases with mixed hemorrhage and 1 case with unclassified hemorrhage. 61.3% of all cases showed the onset during daytime but the remaining awoke in the morning with their symptoms or had the onset from the stage of the bedridden state. The classical prodromal symptoms headache and nausea or vomiting were found in 30% and 54.8%, respectively. Two cases with cerebellar hemorrhage were accompanied by vertigo. Twenty-four patients had consciousness disturbance at admission. There were 18 cases with right or left hemiparetic symptoms, 5 cases with tetraparesis, and 5 cases without motor dysfunction. The remaining already had hemiparesis due to old stroke. Patients with mixed hemorrhage usually exhibited conjugate deviation. In 9 of 31 cases there were mental symptoms such as wandering or night delirium. The 30-day mortality rate was 64.5% and sixty-five percent of them died within 6 days after the onset of ICH. Consciousness at admission was the overwhelming predictive factor.(ABSTRACT TRUNCATED AT 250 WORDS)

The stereotactic aqua-stream and aspirator (SAS & A) was a modification of the aqua-stream and aspirator (AS & A) in order to remove hypertensive intracerebral hematoma. The newly designed needles were held with an adaptor to any kind of Leksell's, Patil's, UT's, Sugita's, or Komai's stereotactic equipment. The needles were stereotactically inserted into the center of the hematoma cavity through a burr-hole. The needles were composed of an outer tube and two inner tubes. The inner tubes were arranged parallel with each other. One was an irrigation tube of 0.1 mm in inner diameter, the other was a suction tube of 2 mm in outer diameter. The blood clot was sucked through a window of the outer tube by the aspirator and incarcerated there soon after. The incarcerated blood clot was crushed by a small streak of saline solution from the nozzle of the irrigation tube. Crushed clot and fluid were sucked through the suction tube. The extent of evacuation of the hematoma was evaluated by CT scans during stereotactic surgery. In all 10 cases of hypertensive intracerebral hematoma, 73-98% of hematoma content was removed. Disturbances of consciousness recovered soon after the surgery. Aphasia and hemiparesis improved later. Hard clot could be removed completely and safely by this new instrument, SAS & A, at an early stage after a stroke, because of the crushing and washing action.

We report a case of familial antithrombin III (AT-III) abnormality accompanied with progressing ischemic stroke. The patient was a 31-year-old female who developed consciousness disturbance and left hemiparesis on December 1 in 1987. She had a history of two transient ischemic attacks and three episodes of thrombophlebitis of the extremities. Cerebral CT scan showed a low density area on the right temporal lobe that had extended to the right parietal and on the left frontal lobe as clinical symptoms worsened. Cerebral angiogram revealed branch occlusions of the right middle cerebral artery and showed no cerebral venous and sinus obstruction. When her symptoms had been progressing to show semi-comatose state, left hemiplegia and transient Cheyne-Stokes respiration, we found her decreased biological activity and normal immunological level of AT-III. The diagnosis of familial AT-III abnormality had been made by familial investigation. As the treatment of AT-III concentrates transfusion was started from the third day, her symptoms gradually recovered and the low density area stopped extending. Further examinations revealed that she was a homozygote of AT-III abnormality presenting no affinity for heparin and that her parents were heterozygotes. It was suggested that the homozygous AT-III abnormality was the main cause of her progressing ischemic stroke.

Risk factors of death for a population of 409 patients with well-defined cerebrovascular disease (patients with subarachnoidal hemorrhage excluded) admitted to the Stroke Unit were studied with the aid of the life table technique, log rank test, and multivariate analysis with BMDP's program for regression on the survival curves with Cox's proportional hazard model. The estimated proportion of survivors was 77% after three months, 69% after one year, and 32% after five years. Patients with intracerebral hemorrhage and embolic cerebral infarction had the worst outcome. Impaired consciousness on admission was the most important risk factor of death followed by high age, previous cardiac failure, diabetes mellitus and male sex.

A small initial dose of prazosin ranging from 0.5 to 1 mg has been recommended to avoid the first-dose phenomenon characterized by a sudden and severe drop in blood pressure after the administration of the first dose of prazosin. However, even with an initial dose of 0.5 mg, hypotension with consciousness disturbance developed in three hypertensive patients with recent cerebral hemorrhage. We present this report to alert physicians and pharmacists about the potential risk of the first-dose phenomenon even at the recommended initial doses of prazosin in hypertensive patients who have suffered a recent stroke.

We describe a 74 year old man who showed the jaw opening phenomenon by painful stimuli from two months after the onset of basilar artery thrombosis. He was admitted to our hospital because of consciousness disturbance and paralysis of all extremities. Soon after admission, he was in a state of impending herniation but with conservative therapy he recovered slightly, and then fell into an akinetic and mute state. Two months after the onset of the stroke, he began to open his mouth in response to painful stimuli, and five months after the stroke palatal myoclonus also appeared. Neurological signs and symptoms five months after admission were as follows; he was akinetic, mute and always kept his eyes closed because of complete blepharoptosis due to oculomotor nerve palsy. Pupils were dilated and adducted. Bilateral light reflexes were absent and the oculocepharic reflex could not adduct the eyes inwardly. Bilateral corneal reflexes were present, facial reflexes were exaggerated and jaw reflexes were also active. All limbs were spastic and paralyzed, and no voluntary movement was observed. Deep tendon reflexes were active in all extremities, and bilateral plantar responses were extensor. Palatal myoclonus was recognized in his soft palate, lips, sternocleidomastoid and diaphragm. Its frequency was about 150 cycles per minute. CT scan revealed severe low density areas in the midbrain and bilateral posterior lobes. In cerebral angiography, the upper part of the basilar artery was completely occluded.(ABSTRACT TRUNCATED AT 250 WORDS)

Stroke was the leading cause of death in Taiwan for 19 years (1963-1981). About 60% of the hospitalized patients dying of stroke suffered from cerebral hemorrhage (CH). This fact denotes an important role of CH in causing fatal stroke. The widely use of computed tomography (CT) in Taiwan in the past decade enables clear differentiation between CH and cerebral infarction (CI). In Taiwan, the ratio of CH: CI is 1:1.5, which is 3.5 times higher than that of the Western countries. CH is most prevalent between aged 55 and 65 years; the male to female ratio after adjusted to that of general population is around 1.1:1. Hypertension is the most important risk factor (86.7%) and spontaneous CH is, therefore, often referred to as "hypertensive CH". CH has a predilection to occur in the putamen (41%), thalamus (23%), putaminothalamus (9.7%), subcortical white mater (9.3%), brainstem (6.5%), and cerebellum (5.9%). Motor dysfunction (80%) is the most frequent clinical manifestation, followed by disturbance of consciousness (50%), and language problems (31.1%). In addition to motor and consciousness disturbance, vomiting (30.8%) and headache (27%) are among important initial presentations, especially for cerebellar and intraventricular hemorrhage. For patients with stable condition after CH, medical treatment is the mainstay of therapy. If condition deteriorates during medical treatment, surgical intervention may be considered for patients with cerebellar, lobar, or putaminal hemorrhage. In Taiwan, 11.6% of patients with CH receive surgical treatment. The mortality rate one month after CH was 53.7% before the CT era; it has decreased to 23.3% in recent years.(ABSTRACT TRUNCATED AT 250 WORDS)
