[Angiographically visualized extravasation in a case of arteriovenous malformation: the first case in Japan (author's transl)].

A case of arteriovenous malformation (AVM) with angiographically visualized extravasation of contrast medium on carotid angiography has been reported. The patient, a 9-year-old girl, came to our clinic with chief complaints of unconsciousness and left hemiplegia. On right carotid angiogram, done 4 hours after stroke, an AVM with a large intracerebral hematoma at the region of the right basal ganglia was recognized. The AVM was feeded from several lenticulostriate arteries and a small branch from precentral artery, and drained into thalamostriate vein. The extravasation of contrast medium was seen in a sash like fashion through arterial and venous phase. Extravasation of contrast medium from AVM has been extremely rarely reported, and this is considered as the third reported case. From the study of these 3 cases, we have discussed about the rarity of the extravasation from AVM and the causative factors.

[Aneurysmal bone cyst of the skull -a case report- (author's transl)].

Aneurysmal bone cyst of the skull is rarely seen. There are 29 reported cases in the literatures as far as we could collect. We reported an additional case of aneurysmal bone cyst of the skull which originated from the right parietal bone of 4-year-old boy. We have summarized these 29 cases. The age incidence in this series is from 14 month-old to 31 year-old. There are 11 cases under the age of 10. In most cases clinical symptoms are palpable mass or headache and exophthalmos. Eyeball displacement and proptosis are also the symptoms when this disease occurs at the orbital roof. According to the characteristic radiographic appearance, it is "blown-out pattern with a shell of periosteal new bone over the mass or soap-bubble appearance". However in our case the radiological finding was osteolytic. It is possible to remove totally when this lesion occurs in the cranial vault, but only curettage may be performed when the skull base is involved. Total removal is the best treatment. Radiation therapy is usually done in the recurrent cases. It is necessary to follow up for at least 4 years because of the rarity of recurrence beyond 4 years after the initial treatment. We also described the other differential diseases and pathogenesis of this disease.

Effect of plasma-cholinesterase preparation on the phase II block of succinylcholine chloride in man.

The effect of enriched human plasma-cholinesterase preparation on the phase II block of succinylcholine chloride was studied in man during anesthesia and surgery. Intravenous administration of 8 esterase units/kg of plasma-cholinesterase did not show any discernible effect on the phase II block of succinylcholine chloride, while edorphonium 10 mg clearly antagonized the block. The finding of the present study suggests that the preparation may be ineffective for patients with a prolonged apnea following the administration of succinylcholine chloride.

[Neuromuscular blocking properties of tobramycin, dibekacin and ribostamycin in man (author's transl)].

Neuromuscular blocking properties of tobramycin (Tobracin 60mg), dibekacin (Panmycin 100 mg) and ribostamycin (Vistamycin 1g) were studied in man during anesthesia and surgery by observing the effects of these antibiotics on muscle twitch tension. These antibiotics alone did not show any neuromuscular blocking action in the therapeutic doses. The neuromuscular blocking action of d-tubocurarine chloride was potentiated by the intravenous administration of 1g of ribostamycin. Tobramycin 60mg did not show remarkable effect, but dibekacin 100mg produced a slight potentiating effect on the action of d-tubocurarine. The enhancement of the action of d-tubocurarine was anatagonized by edrophonium and calcium. The action of succinylcholine chloride was not affected by tobramycin or ribostamycin, but it was potentiated transitorily by dibekacin. It is advisable to pay attention to possible respiratory depression when ribostamycin and dibekacin and used in combination with non-depolarizing muscle relaxants and/or anesthetics.
