The effect of acupuncture treatment on ending peripheral facial nerve paralysis was examined using standard set by the Japan Society of Facial Nerve Treatment. A comparison was made of how recovery was affected by acupuncture treatment alone, drug treatment alone, and a combination of drugs (steroids) and acupuncture.
As a result we found that 1) in groups having an ENoG of 41% or more, the acupuncture-only group showed less recovery than did the group that received oral steroids. 2) Among the groups having an ENoG of 21% or more, there was no significant difference between the group given oral steroids and the group given both steroids and acupuncture treatment. 3) For groups having an ENoG of 1%-20%, there was no difference in recovery between the group given large doses of injected steroids and the group given large doses of injected steroids concommitant with acupuncture. But the group that was given both oral steroids and acupuncture did not recover as well as the other groups. 4) A comparison of the groups receiving only medication and receiving medication with acupuncture showed there was no special hastening of recovery seen with the administration of acupuncture; in fact, the acupuncture may have even delayed recovery.
The above results indicate that the administration of steroids is more important than the use acupuncture in the treatment of peripheral facial nerve paralysis, and that a suitable treatment should commence within 7 days after the occurrence of symptoms.

Objective : To examine the association between the combination therapy of calcium antagonists with angiotensin converting enzyme (ACE) inhibitors and underlying diseases for hypertensive patients.
Design : Cross-sectional survey of the drug utilization.
Methods : This survey included 603 hypertensive patients who had visited Toyama Medical and Pharmaceutical University Hospital, Toyama, Japan more than twice from January to June in 1996 and received the prescriptions of calcium antagonists and/or ACE inhibitors. Main outcome measure was the combined medication of calcium antagonists with ACE inhibitors. Underlying diseases under consideration were diabetes mellitus (DM), hyperlipidemia (LIPID), ischemic heart disease (IHD), chronic heart failure (CHF), and ischemic stroke (STROKE).
Results : Out of 603 hypertensive patients, 57.5% received only calcium antagonists, 23.7% received only ACE inhibitors, and 18.7% received both of them. Patients with either IHD or CHF tended to receive the combination therapy as compared to DM or LIPID. Although men tended to receive the combination therapy, a gender effect might be a confounder for the association. Logistic regression showed a 33% increase (P=0.265) in frequency of the combination therapy in patients with IHD after adjusting for age and gender.
Conclusion : Some underlying diseases were associated with more frequent prescriptions of the combination therapy for hypertensive patients, especially with ischemic heart diseases. This result should be regarded as an exploratory stage although the pattern of antihypertensive drug use could be reasonably explained from the pharmacological sense.

[Objective]Using cotton to cover needle shafts when removing acupuncture needles is recommended in order to prevent blood contamination. However, the effect of risk reduction has not been confirmed by experimental studies. We, therefore, observed spreads of fluorescent agent, assumed as blood, with or without alcohol cotton to avoid direct contact between fingers and needle shaft.
[Methods]Subjects were two blind acupuncturists and two acupuncture students. We asked them to insert acupuncture needles to people who played a role of a patient. Of the five acupoints needled, we put the fluorescent agent to one point, and asked the subjects to remove the needles. After all the needles were removed, we took photographs of all points needled and the subjects'hands in order to assess the spread of the fluorescent agent. 'We performed two sessions. In Session A, the subjects used alcohol cotton to cover a needle shaft so that their fingers did not contact the needles directly. In Session B, they did not use alcohol cotton. The subjects were not told that we used the fluorescent agent.
[Results](1) In the forearm of those who were needled, adhesion of the fluorescent agent was not seen in three out of four subjects, in Session A. (2) In two of the four subjects who inserted the needles, the adhesion area of the fluorescent agent in the needle-supporting hands was smaller in Session A compared with Session B. (3) In three of the four subjects who inserted the needles, the adhesion area of the fluorescent agent in the needle-stimulating hands was smaller in Session A compared with Session B.
[Conclusion]It is suggested that covering needle shaft with alcohol cotton during needle withdrawal suppresses the spread of blood contamination.

An 81-year-old man who had a saccular abdominal aortic aneurysm (AAA) with a narrow terminal aorta underwent endovascular aortic aneurysm repair (EVAR) with the Medtronic Endurant^® stent graft system. After 4 days, computed tomography (CT) showed stenosis of the stent graft left limb, which was pressed flat against the right limb at the narrow terminal aorta. We performed re-intervention to dilate the narrow terminal aorta and bilateral limbs with kissing stenting using Express Vascular LD^® (Boston Scientific). After operation his ankle brachial pressure index rose from 0.88 to 0.99 and there was no evidence of stenotic limbs at CT image. We need to be careful about the stenotic limb after EVAR with Medtronic Endurant stentgraft system for AAA with a narrow terminal aorta.

Human fetal cervical vertebrae are characterized by the large zygapophysial joint (ZJ) extending posteriorly. During our recent studies on regional differences in the shape, extent, and surrounding tissue of the fetal ZJ, we incidentally found a cervical-specific structure of synovial tissues. This study aimed to provide a detailed evaluation of the synovial structure using sagittal and horizontal sections of 20 near-term fetuses. The cervical ZJ consistently had a large cavity with multiple recesses at the margins and, especially at the anterior end, the recess interdigitated with or were located close to tree-like tributaries of the veins of the external vertebral plexus. In contrast to the flat and thin synovial cell lining of the recess, the venous tributary had cuboidal endothelial cells. No or few elastic fibers were identified around the ZJ. The venous-synovial complex seems to be a transient morphology at and around birth, and it may play a role in the stabilization of the growing cervical ZJ against frequent spontaneous dislocation reported radiologically in infants. The venous-synovial complex in the cervical region should be lost and replaced by elastic fibers in childhood or adolescence. However, the delayed development of the ligament flavum is also likely to occur in the lumbar ZJ in spite of no evidence of a transient venous-synovial structure. The cuboidal venous endothelium may simply represent the high proliferation rate for the growing complex.

We have previously reported that the thoracolumbar posterior nerve root shows a tortuous epidural course, based on studies of human fetuses near term. For comparison with the cervical nerve, examinations were conducted using frontal, sagittal and horizontal sections of cervical vertebrae from 22 fetuses at 30–38 weeks of gestation. The cervical nerve root showed a short, straight and lateral course near the zygapophysial joint. Multiple rather than single bundles of the cervical posterior root seemed to account for the majority of sensory nerve fibers innervating the upper extremity. Fasciculation of rootlets was evident near the thoracolumbar spinal cord, whereas it was seen in the dural pocket at the nerve exit from the dural sac although both sites were subdural. As in the thoracolumbar region, the nerve sheath was continuous with the dura mater and independently surrounded each of the anterior and posterior roots. Radicular arteries were few in the cervical region. In 2 of the 22 fetuses (31 weeks and 33 weeks), there was a segmental, unilateral abnormality of nerve rootlet fasciculation where the dorsal root ganglion was located lateral or peripheral to the intervertebral region. Long nerve roots running inferiorly are a necessary adaptation to the delayed and marked growth of the thoracolumbar vertebral column.In children, the cervical nerve roots are likely to be affected by movement or dislocation of the vertebrae. The segmental abnormality of the cervical nerve root may be linked to rare variations in the brachial plexus.

A 42 year-old woman with Marfan syndrome, who had replacement of the ascending aorta for acute aortic dissection several years ago, was found to have distal aortic arch aneurysm. The aneurysm had small entries at cervical arterial branches and large re-entry at the left external iliac artery. It was necessary to perform two-staged operation Bentall procedure with total arch replacement and abdominal aortic replacement with re-entry closure. It was usually performed with a primary entry closure for chronic aortic dissection, but massive invasion was expected. We performed catheter angiography for entry and re-entry, and decided to perform preceding re-entry closure. First, we underwent replacement of the abdominal aorta, and then successfully performed the Bentall procedure with total aortic arch replacement. The catheter angiography was useful for decision-making for medical treatment.

An 84-year-old man, who had been given a diagnosis of advanced aortoventricular block 2 years previously, underwent implantation of a pacemaker (PM) through the left subclavian vein. However, 7 months later a skin ulcer developed at the implantation site, but without any evidence of bacterial infection. Therefore, a PTFE-covered PM battery was reimplanted at the same site. Three months later, the skin ulcer recurred and he received a third implantation in the right side. However, another skin ulcer with infection developed in the right side. He was then transferred to our hospital for another PM reimplantation. We covered the battery and the entire lead with PTFE, then placed the PM lead directly into the cardiac muscle, and implanted the PM battery below the rectal muscle under general anesthesia. A patch test 4 months later revealed a positive reaction to nickel and silicon. Finally, we diagnosed pacemaker dermatitis. The patient has remained free of skin ulcers for over 1 year.

We investigated the relationship between body weight reduction and intensity of daily physical activities assessed with 3-dimensional accelerometer during a 3-month exercise program. Twenty-six middle-aged women (58.1±7.4 yrs.) participated in this study. Participants underwent a 90-min endurance exercise intervention once a week, and a 3-dimensionsal accelerometer was attached through the program. Body weight (BW), body mass index, fat mass and percent body fat were reduced significantly (p<0.001), while diastolic blood pressure (p<0.01) and shuttle stamina walking test (p<0.05) improved significantly after the exercise intervention. Moreover, a significant negative correlation was observed between the changes in BW and total activity time (TAT) per day of more than 3METs (TAT≥3METs)(r=−0.580, p<0.01) and TAT≥4METs (r=−0.627, p<0.001). To the contrary, the daily steps and the TAT≥2METs were not related to the changes in BW. After adjusting daily steps, TAT≥3METs (β=−0.630, p<0.01) and TAT≥4METs (β=−0.659, p<0.01) were still significantly related to the changes in BW. These results indicate that weight reduction has a much closer relationship with exercise intensity than daily steps. It is important to keep both quantity and intensity of exercise in the unsupervised exercise program aimed at weight reduction.
