A case of gliosarcoma with a large cyst is reported. A 22-year-old female was admitted to our hospital with complaints of blurred vision and headache. Plain skull x-ray films showed a radiolucent area in the right frontal area. Computed tomography (CT) revealed an iso-dense mass in the right frontal lobe with a large cyst. After administration of contrast medium, the solid part and cyst wall were well enhanced and the content of the cyst was slightly enhanced. CT number of the cyst fluid was increased from 64.2 to 83.5 Hounsfield units, after administration of the contrast medium. Axial T1-weighted magnetic resonance image (MRI) revealed an iso-intense mass with marked enhancement by Gd-DTPA in the same area. A large cyst was shown to be located in the dorsal part of the mass. A small round protrusion, 10 mm in diameter, was found on the anterior portion of the mass on this MRI. Right carotid angiogram showed a tumor stain fed by the frontopolar artery. Right frontal lobectomy including the tumor was carried out with a preoperative diagnosis of glioblastoma. The patient received radiation therapy of 60Gy (whole brain 40Gy; focal 20Gy) and chemotherapy postoperatively. Histologically, necrosis, hemorrhage and endothelial hyperplasia were revealed at the tumor lesion. The tumor was composed of proliferation of glial and mesenchymal elements. The glial element appeared as fibrillary astrocytoma and polar spongioblastoma. The mesenchymal element showed sarcoma. As mentioned above, this tumor was diagnosed as gliosarcoma. It was difficult to make a diagnosis of gliosarcoma preoperatively because of the complex findings similar to malignant gliomas in conventional neuroradiological imaging.(ABSTRACT TRUNCATED AT 250 WORDS)

Residents adjoining a die-casting plant had excessive headaches, numbness of hands and feet, dizziness, blurred vision, staggering, sweating, abnormal heart rhythm, and depression, which led to measurements of neurobehavioral performance, affective status, and the frequency of symptoms. They had all been exposed via well water and proximity to the plant to volatile organic chemicals (VOC) and to polychlorinated biphenyls (PCBs). The 117 exposed women and men and 46 unexposed referents were studied together for simple and choice visual reaction time, body sway speed, blink reflex latency, color discrimination, Culture Fair (a nonverbal nonarithmetic intelligence test), recall of stories, figures, and numbers, cognitive and psychomotor control (slotted pegboard and trail making A and B), long-term memory, profile of mood states (POMS), and scores and frequencies of 34 symptoms. Choice reaction time, sway speed, and blink latency were impaired in both sexes of the exposed group and trail making B was impaired in exposed women. The POMS scores and frequencies of 30 of 34 symptoms were elevated in both sexes, compared to referents. Recall, long-term memory, psychomotor speed, and other cognitive function tests were reduced in exposed subjects and in the referents as compared to national referents. Neurophysiological impairment, and cognitive and psychomotor dysfunction and affective disorders, especially depression and excessive frequency of symptoms, were associated with the use of wells contaminated with VOCs, TCE and PCBs.

A 5-year-old boy with left side optic neuritis, which manifested itself 21 days after the onset of rubella eruption, is reported. Seven days after the onset of rash which persisted for 3 days, he was found to be excessively somnolent and disoriented, and a diagnosis of rubella encephalitis was made at our clinic. Clinical symptoms spontaneously subsided 3 days later. Twenty-one days after the appearance of rash (16 days after the onset of encephalitis) he complained of left frontal headache and blurred vision of left eye. The funduscopic examination revealed the left papillitis. Pattern reversal VEP (PVEPs) evoked by stimuli of left eye showed absence of N75 wave, and a prolonged conduction time and low amplitude of P100 wave. Corticosteroid therapy improved his complaints, funduscopic and PVEPs findings. When the treatment was stopped, the funduscopic findings were exacerbated but were improved soon again by the additional corticosteroid therapy. A delayed onset of optic neuritis after the initial infection and a prompt response to corticosteroid therapy may suggest an involvement of some autoimmune process in the pathogenesis of postinfectious optic neuritis in our case.

Charts from 1,074 consecutive emergency department patients who underwent cranial computed tomography (CT) were reviewed for predictors of a CT abnormality. Twenty-six clinical variables and the results of neurologic examination were compared with cranial CT findings. Patients with focal neurologic deficit, unresponsiveness, and hypertension had an increased risk of a CT abnormality. Blurred vision, trauma, loss of consciousness, headache, and dizziness were each associated with a lower risk of a CT abnormality. Multivariate analysis showed that only focal neurologic deficit and unresponsiveness effectively helped predict a CT abnormality. In patients with negative neurologic findings, only intoxication and amnesia were associated with greater than 10% positive scans and an increased risk for a CT abnormality. The data indicate that positive neurologic findings coupled with intoxication and amnesia would have helped detect 90.7% of the positive scans and provide an effective initial approximation strategy for selecting patients to undergo CT. Although 15 patients with positive scans (1.4%) would have been missed, this strategy would have yielded a negative predictive value of 97.3% and eliminated 53.9% of the CT scans obtained.

We report a case of Creutzfeldt-Jakob disease in a 38-year-old man, transmitted by a cadaveric dural graft. In August 1985, he underwent cranial nerve decompression for hemifacial spasm and received a cadaveric dural graft for dural closure. He had been well until he began to complain of blurred vision and headache in May, 1990. He developed dementia, myoclonus and urinary incontinence over the subsequent 3 months. He was admitted to our hospital in August, 1990. On admission, he was somnolent and showed gait disturbance, myoclonus in extremities and elevated deep tendon reflexes symmetrically. The results of analysis of blood, urinary and cerebrospinal fluid were normal. The initial computed tomography (CT) and magnetic resonance imaging detected no abnormality. Electroencephalography showed typical periodic synchronous discharge (PSD). There was progressive worsening of his neurological symptoms, and this developed into mutism in September, 1990. CT, 11 months after clinical onset, showed marked enlargement of the ventricles and the sulci. In view of his rapid worsening clinical course, PSD findings on electroencephalography, and delayed progressive changes of CT findings, the diagnosis of CJD disease was made. The cadaveric dural graft was suspected as the cause of the patient's condition. Since Thadani et al reported the first case of CJD transmitted by cadaveric dural graft in 1988, 3 other cases have been reported. This is most likely the 5th reported case of Creutzfeldt-Jakob disease transmitted by cadaveric dural graft.

The efficacy of valproic acid in the treatment of intractable chronic daily headache, unresponsive to traditional prophylactic medications, was examined prospectively in 16 patients. Dosage of the medication was adjusted to maintain serum valproic acid levels between 50 and 100 micrograms/mL, provided there were no significant side effects at that level. Valproic acid prophylaxis was of some benefit in only 2 of 16 patients. One of these two patients discontinued therapy due to side effects. Eight of the 16 patients reported side effects which included nausea, diarrhea, anorexia, lethargy, sleepiness, confusion, blurred vision, and decreased libido. In conclusion, valproic acid was not effective in controlling chronic daily headache in the majority of patients in whom conventional therapy had failed, and 50% of patients reported side effects. There is a significant disparity in the reported efficacy of this drug in treating chronic daily headache. This disparity is most likely due to the poorly-defined nature of this variety of headache. It is, therefore, recommended that more stringent definition of this disorder be developed before therapeutic regimens are evaluated.

We report the case of a 53-year-old man presenting with a headache of sudden onset and blurred vision secondary to hemorrhage from a nonfunctioning pituitary adenoma, which had been treated 25 years previously by transcranial surgery and postoperative irradiation. The intratumoral and intracerebral hematoma expanded to three times its initial size because of a recurrent hemorrhage that occurred during a 2-day period while the patient awaited surgery. The mechanisms of hematoma expansion and the management strategy in such a case are discussed, and a review of the pertinent literature is presented.

Due to the age-associated increase in morbidity, many elderly subjects are in need of multiple drug treatment. Multimedications, however, carry a high risk for adverse drug reactions (ADR) and drug-drug interactions (DDI). This risk is especially increased in very old patients since age and morbidity lead to significant changes in body composition and organ functions. Nonetheless, representative and specific information on cumulative risks for adverse effects of multimedications in the aged is not yet available. We used data of the ongoing, population-based Berlin Aging Study (N = 516; age range 70-103 years) to evaluate the cumulative potential for ADR and DDI in a subgroup of participants taking five or more drugs (N = 221; 44.4% of the parent population [estimated]; mean age 85.2 +/- 8.3 years). Computerized algorithms were used to screen all medications for potential ADR and DDI based on standardized information which was derived from the German Physician's Desk Reference and a frequently used textbook on ADR and DDI. As expected, the analyses revealed a significant potential for adverse effects of multimedications. Cumulative totals of 12,221 different potential ADR (54.9 per subject) and 1016 different potential DDI (4.6 per subject) were identified. With regard to ADR, the most prevalent ADR-risks were for gastrointestinal upset (99%), headache (96%), postural hypotension (95%), and vertigo (94%). With respect to these risks, the minimum mean number of potentially offending drugs was 2.3, the maximum was 4.5 per subject. Additionally, 89% were at risk for drowsiness, 87% for blurred vision and 67% for confusion. Altogether, diuretics, digitalis and calcium antagonists accounted for 46% of ADR-risks. With regard to DDI, 85% had at least one drug-combination potentially leading to enhanced drug action, 52% had at least one combination potentially leading to reduced action. Most frequently involved in potential DDI were calcium antagonists (20%), digoxin (18%), and thiazides (17%). Most prevalent specific risks due to DDI were postural hypotension (48%), glycoside intoxication (26%), toxic CNS-effects (22%) and hypokalemia (19%). In conclusion, risks for ADR and DDI should be considered carefully and regularly monitored in elderly patients on multimedications. Stopping unnecessary medications, especially with regard to diuretics, digitalis and calcium antagonists, will lead to a marked reduction of the cumulative risks associated with multimedications in old age.

In 102 patients with inducible supraventricular tachycardia (SVT), 56 women and 46 men aged 20-86 (mean, 52) years, underwent electrophysiologic study. SVTs observed at electrophysiologic study were atrial flutter or atrial fibrillation (32%), the "slow-fast" form of atrioventricular (AV) nodal reentrant tachycardia (45%), orthodromic AV reentrant tachycardia (25%), and atrial tachycardia (9%). More than 1 SVT occurred in some patients. Spontaneous symptomatic SVT frequency prior to oral flecainide varied from 3/day to 1/3 months (mean, 3/month). At electrophysiologic study and during SVT, intravenous flecainide, 2 mg/kg body weight, was given at an infusion rate of 10 mg/min up to a maximum dose of 150 mg. Patients were commenced on oral flecainide if SVT termination occurred during intravenous flecainide administration and if reinitiation was not possible after the total dose of flecainide had been given. In patients with AV nodal reentrant tachycardia and AV reentrant tachycardia further criteria for commencing oral flecainide were SVT termination by ventricular-atrial conduction block and persistent ventricular-atrial block after intravenous flecainide administration. Initial oral flecainide dosage was determined by assessing ability to reinitiate SVT after 50 mg, 100 mg, and the total dose of intravenous flecainide had been given. Eighty-nine patients (87%) remained free of symptomatic SVT over a mean follow-up period of 3.9 years (range, 3 months to 6.5 years). Two thirds were still taking the original dosage of flecainide and the rest were SVT-free on a higher dosage. Oral dosages ranged from 50 to 300 mg/day (median dosage, 100 mg twice daily) Nine patients experienced minor side effects, including, lethargy, dizziness, headache, and blurred vision. There were no deaths and no reports of major proarrhythmic events or other major adverse effects.

Borreliosis or Lyme disease, a tick-borne infection with the spirochete Borrelia burgdorferi, can cause various ocular and neurological symptoms. A 41-year-old man had been repeatedly bitten by ticks in June 1992; 6 months later, the patient complained of blurred vision in both eyes of 1-week duration, bifrontal headache that was more pronounced on the right side, and neck pain that had appeared months earlier and was becoming more severe. On ophthalmoscopy, clover-shaped retinal pigment epithelium detachments around the optic disc were observed in both eyes. The patient's visual acuity was reduced to 0.5 in his left eye. Liquor cells and total protein were significantly increased; however, a hemagglutination inhibition test revealed only moderately increased immunoglobulin values. After 2 weeks of daily application of 4 g ceftriaxone disodium, ophthalmological and neurological symptoms disappeared. Even though the immunoglobulin values remained unchanged, neuroborreliosis with involvement of the retinal pigment epithelium was the most probable diagnosis, considering the history of tick bites and headache. The authors assume that the tissue around the optic nerve head, which does not have an effective blood-brain barrier, allowed the spirochetes to spread from the central nervous system into the subpigment-epithelium space, thus causing the observed parapapillary pigment epithelium detachments.
