We studied the feasibility of intrathecal nicardipine administration using a portable infusion pump system in five cases (two males and three females) of subarachnoid hemorrhage (SAH). All of the five cases manifested severe SAH of Hunt & Kosnic grade 3 or 4, and Fisher CT group 3. Aneurysmal sites of five cases were as follows: three internal carotid-posterior communicating artery (IC-PC) aneurysms and two anterior communicating artery (Acom) aneurysms. The container of the infusion pump system was filled with 105 ml of nicardipine-saline solution (2:1), and this system was connected to the cisternal tube. The solution was continuously injected at a daily dose of 12 ml (8 mg of nicardipine). This therapy was continued for 14 days, and new nicardipine solution was supplied only once at 8 days after the operation during this therapy. No postural restraint of patients was necessary, even during physical movement for rehabilitation. Postoperative angiography was performed in three of five cases at one week after the operation. No angiographic vasospasm was observed in any of the three cases. Symptomatic vasospasm was observed in one case of right IC-PC aneurysm as a transient total aphasia and right hemiplegia, which recovered within several hours due to induced hypervolemia and hypertension therapy. Mild meningitis at 14 days after the operation complicated this treatment in one case, but it improved in a few days after the cisternal tube was removed. It was speculated that meningitis was caused by cerebrospinal fluid leakage from the scalp exit site of the cisternal tube. All of the five cases had obtained good recovery at three months after the operation. These results show that, although this method involves a risk of infection, it has the advantage of easiness and convenience over conventional methods. Though further improvement of this method is required, this preliminary stage is potentially useful for delivering not only nicardipine, but also for other drugs which may be used in intrathecal administration therapy.

The cases of three children, 16, 12, and 12 years of age, who suffered sudden confusional state and cortical blindness lasting 12 to 30 minutes while under treatment with high-dose methotrexate, cyclophosphamide, and dactinomycin for a lower limb osteosarcoma are reported. Transient neuropsychologic deficits arose after the acute phase of treatment: left hemispatial neglect and constructive apraxia (Patient 1); constructive apraxia (Patient 2); and constructive apraxia and alexia without aphasia (Patient 3). The three patients recovered completely from all their deficits within the time frame of 3 hours to 2 weeks. Arterial hypertension and hypomagnesemia were found during the acute phase in all patients. In Patients 2 and 3, magnetic resonance imaging revealed increased parieto-occipital T(2) signal involving gray and white matter. In Patients 1 and 2, HmPAO-SPECT revealed parieto-occipital hypoperfusion that resolved a few days later. The alterations detected by neuroimaging were concurrent with the appearance and disappearance of the clinical symptoms. Such transient acute episodes have been named occipital-parietal encephalopathy. On the basis of our clinical, laboratory, and neuroimaging findings, an explanation for the origin of this syndrome, a migrainelike mechanism, triggered by chemotherapy-induced hypomagnesemia, is proposed.

A rare case of aldosterone-producing adrenocortical adenoma with preclinical Cushing's syndrome and hypersecretion of parathyroid hormone (PTH) is described. A 64-year-old male patient had a history of hypertension for two decades and hypokalemia for 4 years. He suffered from left hemiparesis and aphasia due to cerebral hemorrhage, but his appearance was not Cushingoid. His plasma renin activity was below the normal range, while plasma aldosterone concentration was high. They did not respond to furosemide-upright test. His plasma cortisol level in the morning was at the upper limit of the normal range, but it did not show a diurnal rhythm nor was it suppressed by 1 mg and 8 mg of dexamethasone. Computed tomography showed a low density tumor in the right adrenal gland. An adrenal scintigram under dexamethasone treatment revealed an uptake of the tracer on the right side, and plasma aldosterone and cortisol concentrations in the adrenal vein were higher on the right side than on the opposite. The diagnosis of right aldosterone-producing adrenal adenoma with an autonomous production of cortisol was confirmed by right adrenalectomy. Histological findings showed an adenoma consisting mostly of clear cells, but that the nests of compact cells were scattered. Analysis of an extract from the adenoma revealed that the adenoma contained an excess amount of aldosterone and that the cortisol/corticosterone ratio was higher than that of aldosterone-producing adenoma. Both serum calcium and PTH levels remained high one year after adrenalectomy. Ultrasonography revealed the swelling of a parathyroid gland on the left side, indicating the coexistence of an autonomous hyperparathyroidism.

Psychological disorders of infertile patients are traditionally thought to be chronic, to advance gradually, and to be long-term problems. We describe a patient in whom an acute psychiatric episode developed immediately after transvaginal ultrasound-guided oocyte retrieval. A 34 year old women without history of psychiatric disturbance or adverse reaction to drugs suffered an acute psychiatric episode immediately after oocyte retrieval. She exhibited tachycardia, tachypnoea, transient hypertension and limb rigidity, as well as alterations to stupor and posture. Her vital signs stabilized and she opened her eyes 6 h later, but she persistently raised her head to the left and stared blankly without response to external stimuli. Nine hours later, she was able to look around but remained unresponsive to stimuli. Aphasia was noted in the next morning and a wishful thinking of having delivered a baby was noted in the afternoon. Memory loss was noted on the third day. The patient was diagnosed as having dissociative amnesia and was discharged after three courses of supportive psychotherapy. Assisted reproductive technology-related acute psychiatric episodes, which may initially mimic brainstem stroke, are rare; however, attention should be paid to high-risk patients, and they should be offered elective psychological counselling.

We report a 72-year-old right-handed man who was diagnosed as having crossed aphasia. He had polycythemia, hypertension and an old cerebral infarction in the right occipital lobe. He was admitted to our hospital because of muscle weakness in the left extremities at the age of 71. In the laboratory data, red blood cells(689 x 10(4)/microliter) and platelets(87.6 x 10(4)/microliter) were increased in number. Brain CT detected a right putaminal hematoma and an old infarct in the occipital lobe on the right. After admission, he developed non-fluent speech, and impairments of auditory comprehension, writing and naming due to the infarction in his right cerebral hemisphere including the middle cerebral artery distribution. The standard language test of aphasia(SLTA) revealed marked impairments in the language function, except for reading kana and kanji words. This writing was severely impaired compared with other language dysfunctions. Auditory comprehension, repetition and reading were impaired at the sentence level rather than at the kana word level. Furthermore, he suffered from left hemiparesis and left unilateral spatial neglect. We diagnosed his impairments of language function as crossed aphasia based on his right-handedness, CT findings and the results of SLTA. His language center was considered to be located in both cerebral hemispheres. Compared with typical findings in reported cases of crossed aphasia, the presence of both non-fluent speech and mutism were consistent with previous observations. However, the marked impairments of auditory comprehension, repetition and naming were different. Polycythemia and hypertension were considered to be the risk factors of cerebral infarction in our patient.

Stroke is the main manifestation of cerebrovascular disease (CVD). Few studies report the insidious and progressive development of CVD. The aim of this study was the characterization of a CVD form without stroke in association with vascular subtypes and risk factors (VRF). From 105 CVD patients, 65 had stroke (62%), 13 of them had more than one stroke (20%), and 40 patients had a chronic progressive form (CPF) (38%). Mean evolution times up to maximum neurological deficiency were 1.57+/-0.94 and 344.25+/-210.96 days, respectively. Group results significantly associated with VRFs: hypertension (p=0.0046), hyperlipemia (p=0.0046) and atrial fibrillation (p=0.0173); with clinical manifestations: aphasia (p=0.0018), pyramidal syndrome (p=0.0000001) and small vessel disease (SVD) (p=0.0000001); and with MRI: bilateral infarctions (p=0.00009) and incomplete white matter lesions (IWMLs) (p=0.0061). Within the CPF group, dysarthria and complete infarctions were associated (p=0.00036). Most neurological disorders associated with CVD are related to CPF. The significant correlations of SVD, bilateral infarcts, IWMLs, dysarthria, several VRFs and the strong difference in evolution time up to maximum neurological deficiency values characterize CPF as a separate entity within CVD.

A 55-years-old man with a history of alcoholism, hypertension and obesity was diagnosed of epidermoid carcinoma of the middle third portion of the esophagus. He was treated with two cycles of cytostatics with cisplatin and 5-fluorouracil. Due to his poor general health an inability to swallow solids and liquids, he received parenteral nutrition for 20 days using a commercial formula lacking in vitamins and minerals. During distal esophagectomy we observed a tendency to hypotension and severe metabolic acidosis that was unexplained by the hemodynamic profile and that persisted throughout the first 24 hours after surgery. Once these complications were corrected, he was weaned from mechanical ventilation and the following neurological signs were observed: temporal and spacial disorientation, aphasia, ophthalmoplegia with divergent strabismus and later conduction aphasia, amnesia and confabulation. Circulation was hyperdynamic, requiring inotropics and vasoconstrictors. Korsakoff syndrome secondary to Wernicke's encephalopathy was diagnosed, and the response to thiamine treatment was favorable. Beriberi can be found in hospitalized patients and the anesthesiologist may be involved in their perioperative care. Symptoms resolve easily with vitamin B1 treatment, which is ideally provided along with other hydrosoluble vitamins. Treatment should be prompt because delay leads to greater morbiomortality.

A 47-year-old man lost his consciousness and brought to our hospital by ambulance. On admission, he had aphasia and upper right limb paresis. Diffusion weighted MR image of the brain on admission showed multiple high intensity areas in the left middle cerebral artery (MCA) territory. Brain angiography performed on the 2nd hospital day revealed the left MCA severe stenosis. We started intravenous antithrombotic therapy on the 1st day. The left carotid angiography on 12th day demonstrated that the left MCA stenosis was improved. He had medical history of hypertension, diabetes mellitus and gout. But he had only slight atherosclerosis, and had no arrhythmia and patent foramen ovale. Blood chemistry test showed marked hypoproteinemia and hyperlipidemia, and urine examination showed proteinuria. He was diagnosed as nephrotic syndrome for the first time. Nephrotic syndrome brought hypercoagulability, so we suspected that nephrotic syndrome concerned with brain infarction.

The central neurotoxicity of cyclosporin A (CsA) has been abundantly documented in pediatric and adult recipients of bone marrow or organ transplants, with variations in the rate of occurrence from 0.5% to 35%. We report two cases of central neurotoxicity ascribable to CsA in children with nephrotic syndrome due to lipoid nephrosis. The manifestations of CsA-related central neurotoxicity include confusion, aphasia, dystonias, akinetic mutism, parkinsonism, palsies, seizures, catatonia, coma, brain hemorrhage, and cortical blindness. Decreased density of the cerebral white matter is visible by computed tomography (CT) in 50% of cases, with the most commonly involved sites being the occipital cortex, the cerebellum, the periventricular substance, and the brainstem. Magnetic resonance imaging is more sensitive and more specific than CT for investigating the white matter. High-signal lesions are seen on T2-weighted sequences in the areas that are abnormal by CT. Many risk factors have been reported, including hypomagnesemia, hypocholesterolemia, high-dose glucocorticoid therapy, arterial hypertension, and infections. We present two patients with central neurotoxicity both of whom have elevated cholesterol levels.

Aneurysms arising from a lenticulostriate artery (LSA) are uncommon. Their causes include hypertension, moyamoya disease, infection, systemic lupus erythematosis, and flow-related saccular aneurysms. Options for treating these aneurysms are limited. The authors present a case in which an LSA aneurysm was identified in a 69-year-old woman with no significant medical history, who experienced a sudden onset of right hemiparesis and aphasia due to a basal ganglia hemorrhage. The different causes and treatment options available for these rare and difficult-to-treat aneurysms are discussed.
