A 61-year-old man with aortic regurgitation was found to have a quadricuspid aortic valve during operation. The aortic valve consisted of four equal sized cusps with an accessory cusp located between the left and right coronary cusps. The right coronary ostium was placed in a lower position. Aortic replacement with a St. Jude Medical prosthesis was performed successfully. Quadricuspid aortic valve is a rare anomaly and 14 cases of quadricuspid aortic valves in the Japanese literature which were corrected surgically are reviewed.

In von Recklinghausen's disease vascular involvement is rare, especially rupture of peripheral arterial aneurysms. A 65-year-old man with previously diagnosed neurofibromatosis was admitted because of left lateral neck and left shoulder pain. Computed tomography and selective left subclavian angiography revealed ruptured aneurysm of left costocervical artery, and therefore an emergency operation was performed. Left costocervical artery was exposed and proximal ligation of the aneurysm was performed. Angiography is a most useful and important procedure in operations for vascular involvement in von Recklinghausen's disease.

[Objective] The purpose of this study was to compare the effectiveness of acupuncture and local injection for neck pain.
[Methods] A randomized controlled clinical trial was conducted in which 33 patients with neck pain were randomly allocated to either an acupuncture group or a local injection group. For the acupuncture group (n=16), a stainless steel needle was inserted to a depth of 10 to 20 mm and manually stimulated (sparrow pecking method) for 20 seconds. A 25 gauge needle was inserted to a depth of 10 to 20 mm and neovitacain (dibucaine hydrochloride 0.1%, sodium salicylate 0.3%, calcium bromide 0.2%) and neurotropin (non protein component extracted from the skin of rabbits treated with vaccinia virus) were injected for the local injection groups (n=17). Both groups received each treatment at the most painful points weekly for four weeks. Primary outcome measurement was intensity of the pain evaluated with a visual analogue scale (VAS). Secondary outcomes were the Neck Disability Index (NDI) and a standardized questionnaire of cervical root disease (developed by Tanaka et al. at Tohoku Univ.). The evaluations were independent from the therapists.
[Results] The acupuncture groups showed better results in all the outcome measurements than those in the local injection group for the effect immediately after the treatment, the effect of sequential treatment and the continuing effect after completion of treatment.
[Discussion] The result of this study suggested that acupuncture can be a useful treatment method compared with local injection. The difference in the effects between the two treatment methods may be due to the difference in the mechanism to suppress pain.

The effects of electrical acupuncture at the patellar tendon and electrical stimulation of the femoral nerve on patellar tendon blood flow were evaluated using laser Doppler flowmetry in anesthetized rats. In most subjects the blood flow in the patellar tendon rapidly decreased for 30 seconds after the start of local electrical acupuncture and then increased above baseline. Changes in blood flow did not necessarily follow changes in arterial blood pressure. Changes in tendon blood flow induced by electrical stimulation of the femoral nerve were similar to those induced by electrical acupuncture at the patellar tendon. Arterial blood pressure and heart rate were not affected by electrical stimulation of the femoral nerve. Phentolamine administration abolished the decreased patellar tendon blood flow seen after initiating electrical acupuncture at the patellar tendon, whereas atropine abolished the increased patellar tendon blood flow seen after terminating electrical acupuncture at the patellar tendon. Furthermore, atropine did not evoke increased blood flow following electrical stimulation of the femoral nerve. These results suggest that the decrease of blood flow seen after initiating electrical acupuncture may be controlled by sympathetic vasoconstrictor nerves and the increase of blood flow following electrical acupuncture may be controlled by cholinergic vasodilator nerves.

We applied electrical acupuncture to the spinal nerve root by inserting needles under x-ray control in two cases with radicular sciatica as a non-pharmacological substitute for the lumbar spinal nerve block. In both cases, symptoms were markedly reduced after electrical acupuncture to the spinal nerve root. The sustained effect was noticeably longer than that of caudal anesthesia previously performed one time on one of the cases. We suggest that descending inhibitory control, inhibitory control at the spinal level, or changes in nerve blood flow may be involved in the mechanism of the effect of electrical acupuncture to the spinal nerve root. These results suggest that electrical acupuncture to the spinal nerve root may be superior to lumbar spinal nerve block or caudal anesthesia when it is applied appropriately in certain cases of radicular sciatica, taking into consideration of patient age, severity of symptoms and duration of the disorder.

We studied the clincal effect of the electrical acupuncture at pudendal nerve in four cases of lumbar spinal canal stenosis. The experimental effect of the direct electrical stimulation to the pudendal nerve on the blood flow of the sciatic nerve evaluated by Laser-Doppler flowmetry in anesthetized rats. Electrical acupuncture at pudendal nerve resulted in the improvement of the gait distance of all four cases. The specific effect of the electrical acupuncture at pudendal nerve was found in one case who did not show any improvement by the acupuncture at the intervertebral joint points. On one hand, the direct electrical stimulation to rats pudendal nerve resulted in the increase of the sciatic nerve blood flow, which were not evoked by administration of atropine. These results suggest that the electrical acupuncture at the pudensal nerve may be effective for the intermittent claudication of the lumbar spinal canal stenosis. The increased blood flow of the sciatic nerve may play one of the important roles in the effect via autonomic nervous system.

[Objective] To examine the effect of moxibustion treatment for reducedpain during activity due to hallux valgus.
[Methods] The subjects were five young females with pain due to hallux valgus. Indirect moxibustion treat-ment was carried out on the region of maximum pain to relieve pain. Moxibustion was performed once per day for 2 weeks, for a total of 14 times. Evaluation used the number of side steps performed and the pain (Numerical Rating Scale) at the time of a side step.
[Results] After moxibustion treatment, pain improvement was observed in all subjects at the time of a side step. At the same time, the number of side steps increased. Repeated measurements before and after moxibustion indicated that there was no significant learning effect.
[Discussion and Conclusion] It became clear that the pain due to hallux valgus is mitigated by moxibustion over a fixed period, while athletic ability with respect to side steps is also improved. These results suggested the pain during activity due to hallux valgus is controllable with moxibustion treatment. By controlling pain, moxibustion treatment also temporarily improves athletic ability.
