ジャーナル フリーThe gravimetric method to determine the tissue water content is widely used for studying brain edema because the tissue water content can be calculated from only the density of the wet tissue using a gradient column. This method has been used in only a few studies of cerebellar water content. We estimated the water content of the cerebellar cortex by the gravimetric method and compared the results with those measured by the conventional drying-weighing method, and found a significant difference. We therefore propose modified coefficients for the equation for the water content of the cerebellar cortex as follows:
% tissue water content = 456.13(1/wet tissue density)-356.13
This equation and the drying-weighing method were used to investigate normal and edematous cerebellar cortices after compression with an epidural balloon. The modified equation provided results consistent with the drying-weighing method. Differences in the total experimental system including the breed and pre-experimental condition of the cats may be factors in variations in measured values. We recommend that investigators establish equation coefficients valid for individual experimental systems.抄録全体を表示PDF形式でダウンロード (389K) -

ジャーナル フリーSpinal cord intramedullary pressure was measured in eight mongrel dogs using a balloon method. The neck of the animals was maintained in the neutral position. Following cervical laminectomy, the cervical spinal cord was drawn dorsally using a small plastic saddle inserted ventral to the spinal cord at the C-5 level. The cord pressure at C-5 increased with traction load. The cord pressure at C-6 not in direct contact with the plastic saddle also increased to about one third the increase at C-5. These findings indicate that spinal cord intramedullary pressure is increased by mechanical compression on the anterior structure of the spinal canal and stretching of the cord to some extent. This phenomenon might be important in cord insult in patients with spinal column lesions located anterior to the spinal cord and presenting with neurological signs extending over several segments.抄録全体を表示PDF形式でダウンロード (190K) -

ジャーナル フリーPostoperative chronic subdural hematoma (CSH) following craniotomy developed in only four of 372 patients undergoing craniotomy for aneurysm surgery (1 patient) and brain tumor surgery (3 patients) between April, 1991 and November, 1993, an incidence of only 1.1%. There were three males and one female, aged from 32 to 66 years (mean 56 yrs). The period between craniotomy and development of CSH ranged from 3 to 5 months (mean 4.3 mos). Postoperative hematomas were located on the operative sides in three patients and the contralateral side in the other. Early postoperative computed tomographic scans found subdural fluid collection in all patients. Magnetic resonance images showed linear meningeal enhancement in all patients. Postoperative CSH may be caused by mixture of blood in subdural cerebrospinal fluid collection which persists due to reduced brain elasticity and wide subarachnoid membrane opening resulting in neomembrane formation and finally development of hematoma.抄録全体を表示PDF形式でダウンロード (404K) -

ジャーナル フリーA 5-year-old girl and a 2-year-old boy presented with recurrent cerebral primitive neuroectodermal tumor (PNET) and were treated with intravenous administration of human fibroblast interferon (HuIFN-β) which was continued as outpatient maintenance therapy. Both patients showed a partial response and were still alive 14 months and 2 years after diagnosis. Our results suggest that HuIFN-β is an effective therapy for PNET, and can be used as long-term maintenance therapy without serious side effects.抄録全体を表示PDF形式でダウンロード (539K) -

ジャーナル フリーA 9-year-old boy presented with a meningioma containing a large cyst. Magnetic resonance (MR) imaging demonstrated tumor cells in the solid part of the tumor, part of the cyst wall, and cyst septum. The presence of the tumor cells in the thin cyst wall or the cyst septum is important to recognize preoperatively, and MR imaging is very useful to differentiate intratumoral cysts from peritumoral cysts in meningiomas.抄録全体を表示PDF形式でダウンロード (705K) -

ジャーナル フリーA 45-year-old female presented with a recurrent peritorcular meningioma. The recurrence was very unusual as the tumor arose from the confluens sinuum and extended to the left jugular bulb completely within the sinuses, obstructing the venous outflow. However, there were no clinical symptoms or neurological abnormalities, due to the development of collateral circulation. The possibility of intrasinus recurrence should always be considered in patients with tumor invasion to sinus walls, even if the patient has no clinical symptoms or neurological abnormalities.抄録全体を表示PDF形式でダウンロード (516K) -

ジャーナル フリーA 25-year-old female presented with amenorrhea and bitemporal hemianopsia without diabetes insipidus due to an intra and suprasellar dumbbell tumor. The preoperative and operative diagnosis was pituitary adenoma, but the histological diagnosis was germinoma. Differential diagnosis between germinoma and pituitary adenoma based on computed tomograms and magnetic resonance (MR) imaging features and signal intensity characteristics was difficult in this patient. An enhanced mass posterior to the normal pituitary gland on the mid-sagittal MR image normally indicates an intrasellar germinoma rather than a pituitary adenoma, but this finding was equivocal in our patient.抄録全体を表示PDF形式でダウンロード (353K) -

ジャーナル フリーA 52-year-old female presented with an unusual large cystic cavernous angioma with dense calcification in the thalamus manifesting only as headache despite the large mass with surrounding brain edema. BothT1 , and T2-weighted magnetic resonance images revealed a large cystic mass with an intramural nodule appearing a reticulated, irregular mixed intensity core. The lesion was totally removed through a transcortical-transventricular approach. The postoperative course was uneventful with no signs of neurological deficit or residual mass 5 years later.抄録全体を表示PDF形式でダウンロード (481K) -

ジャーナル フリーA 72-year-old female presented with non-communicating hydrocephalus due to megadolichobasilar artery manifesting as drowsiness and Parinaud''s sign. Neuroimaging demonstrated enlarged third and lateral ventricles and the tortuous, elongated basilar artery compressing the interpeduncular segment of the midbrain, resulting in occlusion of the aqueduct. Emergency ventricular drainage subsequently replaced by a ventriculoperitoneal shunt achieved complete resolution of the enlarged ventricles. This is the first report of megadolichobasilar artery causing this type of obstruction and manifesting as rapidly progressive hydrocephalic symptoms.抄録全体を表示PDF形式でダウンロード (296K) -

ジャーナル フリーA 30-year-old female experienced a sudden sharp pain radiating down to the left leg from the lower back at epidural intubation for anesthesia at childbirth. She continued to complain of pain in the left leg afterwards. Magnetic resonance images demonstrated a conglomeration of adherent nerve roots due to lumbar adhesive arachnoiditis. Microsurgical dissection of adherent nerve roots was performed. Her symptoms disappeared after surgery, but soon recurred, being less severe and responsive to anti-inflammatory agents. Lumbar adhesive arachnoiditis should be considered for differential diagnosis in patients presenting with back and leg pain syndrome.抄録全体を表示PDF形式でダウンロード (303K)
