    It is important to assess the general bone condition when performing dental implant treatment. The classification of the mandibular cortical bone index (MCI) using multi-slice computed tomography (MSCT) could be applicable to evaluate the general bone condition. In an investigation involving women, MCI-CBCT was classified using cone-beam CT (CBCT), and MCI-CBCT was compared with MCI-MSCT. A total of 32 women who had undergone diagnostic imaging for mandibular dental implant treatment using multi-slice and cone-beam CT were enrolled in this investigation. Cross-sectional images from the mental foramen to the anterior margin of the mandibular ramus were continuously reconstructed from mandibular data of multi-slice and cone-beam CT. Subsequently, MCI-MSCT and MCI-CBCT were visually classified into two types: homogeneous and osteoporotic, and MCI-CBCT was compared with MCI-MSCT. The homogeneous type included 18 subjects and osteoporotic type included 14 subjects using cone-beam CT. The types were in agreement between MCI-MSCT and MCI-CBCT in 30 of the 32 subjects. Two of the 20 subjects classified into the homogeneous type using MCI-MSCT were classified into the osteoporotic type using MCI-CBCT. MCI-CBCT could be visually classified into two types, and may be applicable to evaluate the general bone condition.

    For dental implant treatment, it is important to assess the general bone condition. Using multi-slice CT scans, we assessed the relationships between the bone mineral densities (BMDs) of the cervical and lumbar vertebrae in postmenopausal women to see if such data might be useful for imaging-based diagnosis prior to dental implant treatment. Thirty postmenopausal women were enrolled in this investigation, and their third cervical vertebrae were scanned for BMD using multi-slice computed tomography (CT) while the lumbar vertebrae were measured using dual energy X-ray absorptiometry, after which the percentage of the young adult mean (YAM) was calculated. The correlations between the BMD of the cervical vertebra and percentage of YAM were analyzed. The mean BMD of the cervical vertebra was 255 mg/cm3 HA (s.d.: 28.8) in the normal group, 233 mg/cm3 HA (s.d.: 44.3) in the osteopenic group, and 178 mg/cm3 HA (s.d.: 35.9) in the osteoporosis group. A significant difference was observed between the normal and osteoporosis groups, and between the osteopenic and osteoporosis groups. A correlation (r = 0.705) was observed between the BMD of the cervical vertebrae and percentage of YAM of the lumbar vertebrae. The BMD of the third cervical vertebrae obtained from multi-slice CT images might be applicable in dental implant treatment to evaluate the influence of the general bone condition.

    Since high levels of prions, the causative agent of bovine spongiform encephalopathy (BSE), accumulate in the brain and spinal cord, contamination of beef carcasses with central nervous system tissue (CNST) may occur at post-slaughter process. In this study, we investigated CNST contamination on the surface of beef carcasses using glial fibrillary acidic protein as a marker after splitting and evaluated the effects of washing procedures on contamination removal. High levels of CNST contamination was detected immediately after splitting, especially in the area close to the spinal column. This suggests that spinal cord fragments are attached to carcasses at the time of splitting even though the spinal cords have been removed by vacuum before splitting. Steam cleaning or manually washing with normal pressure water around the spinal column, performed prior to washing with high-pressure water, was found to be effective for reducing the level of CNST contamination. Furthermore, manually washing with high-pressure water could reduce CNST contamination to almost negligible levels. These results are useful for preparation of appropriate sanitation standard operating procedures to reduce the risk of CNST contamination of carcasses for prevention of exposure to BSE prion via the food chain.

    A 35-year-old man developed a cerebral infarction and experienced transient ischemic attacks originating from the vertebrobasilar artery, as well as locked-in syndrome. He recovered with minimal neurological deficit. On cerebral angiography, the orientation of the right vertebral artery was markedly abnormal as it entered the foramina of the transverse process at the level of the third cervical vertebra. We concluded that the abnormal orientation of the vertebral artery caused the thrombosis and that the transient ischemic attacks, locked-in syndrome and cerebral infarction were brought about by thromboemboli originating in this artery.

    かつてMORIMOTO(1987)が報告した南北朝期における打ち首2例の追加として,1991年に鎌倉市比由ケ浜中世集団墓地から出土した同時代の壮年期男性頭蓋1例を提示する.この頭蓋は第1~4頸椎•舌骨とともに墓地に埋められていた.他の骨格部分はない.頭蓋には6個の刀創が見られる.うち3個は死の直前に受けたもので,前頭鱗右側を左前方から右後方に斜めに走って板間層に達する長さ45mmの刀創(a),右眼窩外側縁の骨をそぎ落とした刀創(b),右頭頂骨を前後方向に走って頭蓋冠表面と接線方向に浅く頭蓋腔に達した刀創(c)であるが,これらは浅く,直接死因ではなさそうである.残りの3個は,後頭骨右下項線をそぎ落とした刀創(d),右下顎枝後縁にほぼ水平に切り込んだ2個の刀創(e, f)である.後頭骨の刀創(d)は打ち首の時か死後のものかは分からないが,右下顎枝の刀創(e, f)は,後述する軸椎の刀創(i, h)とそれぞれ一致する.
    いっぽう頸椎には右後方から鋭く切り込んだほぼ水平に走る5回分6個の刀創が認められる.上方から順に,環椎の椎弓下縁をかすめて(9),軸椎歯突起の後部に達して止まる刀創(h),軸椎の椎弓上部と右上関節突起後部を切り軸椎体に達して止まる刀創(i),軸椎の棘突起を右後下方から切って椎弓内で止まる刀創(j),第3頸椎の棘突起•右下関節突起•椎弓•椎体を右後下方から切って左椎弓根で止まる刀創(k).第4頸椎の棘突起•右下関節突起•椎体下部を切り離して椎体の左1/4部で止まる刀創(1),である.
    上述のように環椎の刀創(g)および軸椎の刀創(h)は右下顎枝後縁の刀創(f)と,また軸椎の刀創(j)は右下顎枝後縁の刀創(e)と,それぞれ一致する.舌骨に刀創は見られなかった.
    打ち首された時の創傷は環椎•軸椎•右下顎枝に残る刀創(g+h+f)か,または軸椎の刀創(i)のいずれかと推測され,これは頸髄•右椎骨動脈を完全に横切し,致命的である.また軸椎•右下顎枝の刀創(j+e)および第3•4頸椎の刀創(k)•(i)は死後頭部を切り離した際に加えられたものと思われる.本例はたぶん手負いの武士が名を重んじ首を打たれたものであろう.
    江戸時代には「打ち首は頸の前皮一枚残して切るのが常法」と言われたが,古い日本の半切りによる打ち首の伝統の起源が南北朝期までさかのぼり得ることを示す好例として,先の2例とともに本例は注目される.

    Hyoid bone syndrome is a disease caused by an abnormality in the apparatus hyoideus, indicated by a variety of symptoms such as a feeling of discomfort in the pharyngolarynx, neck pain, a clicking sound when twisting the neck, etc. We report on two cases of hyoid bone syndrome accompanying an excessively long greater cornu of the hyoid bone.

    Case 1 consulted the hospital with the excessively long of discomfort when swallowing along with a clicking sound when swallowing from several years prior. The greater cornu of the hyoid bone on both sides was found to be long upon neck CT, in addition to approaching the transverse process of the fourth cervical vertebra. Case 2 became aware of neck pain from 1 year prior and consulted the hospital due to exacerbation of the symptoms. The excessively long greater cornu of the hyoid bone was observed on both sides of neck on CT imaging, with the greater cornu of the hyoid bone approaching the transverse process of the third cervical vertebra. From the above, the patient was diagnosed with hyoid bone syndrome accompanying an excessively long greater cornu of the hyoid bone on both sides, with prominent improvement in symptoms observed when partial resection of the bilateral greater cornu of the hyoid bone was carried out, yielding good results.

    Although such cases may be diagnosed as pharyngolaryngeal paresthesia, when symptoms are observed over a long period of time and the complaint is strong and clear, an in-depth examination including imaging testing is required. Moreover, it was believed that resection of the greater cornu of the hyoid bone is a useful treatment for hyoid bone syndrome.

    Malignant lymphoma with osteosis is a rare disease. We report a case of malignant lymphoma seen in the third cervical vertebra body. A 63-year-old man experienced mild neck pain. Deep tendon reflexes were normal and symmetric. Sensory was intact. MMT was all 5. In the radiography, we found a lytic change in the third cervical vertebral body. We suspected metastatic tumor, but we could not find the primary tumor. We operated with instruments for spinal support. Diagnosis of the malignant lymphoma (B cell type) was by the post operative pathological examination. We performed chemotherapy. 4 months after surgery, there was no recurrence.

    [Purpose] The objective of this study was to compare the active cervical range of motion (CROM) of asymptomatic subjects without orthosis with wearing cervical soft collars or with cervical 5cross-taping. [Subjects] Twenty-three asymptomatic subjects (13 males, 10 females) without neck or shoulder pain agreed to participate in this study. [Methods] The active neck movement (flexion, extension, and left and right rotation and lateral flexion) of the subjects was measured using a CROM instrument without orthosis, while wearing a cervical soft collar, and with cervical-5 cross-taping. [Results] All active neck movements with cervical-5 cross-taping were significantly reduced compared to without orthosis. All active neck movements while wearing soft cervical collars were significantly reduced compared to without orthosis and cervical-5 cross-taping. [Conclusion] These preliminary results suggest that cervical-5 cross-taping using Kinesio tape may allow more active neck movement than soft cervical collars and be more supported than without orthosis.

    Operative treatment was applied for an old unreduced dislocation of atlas with nonunion of odontoid process and incomplete C-1 quadriplegia. Reduction wasn't performed with conservative treatment such as skull traction and halo-pelvic traction. Furthermore, reduction wasn't succeeded through transoral approach, but decompression was performed with resection of anterior arch of atlas and odontoid process. After all, posterior cervical fusion from occiput to third cervical vertebra was performed, so pain and paresthesia were improved.

    Forty-three cases of cervicovestibular syndrome were treated by perivascular sympathectomy at the proximal part of the vertebral artery. These cases were divided into P (peripheral) and C (central) groups by the positioning nystagmus test (Dix and Hallpike 1952) and self-recording cupulometry (Hozawa and Sasaki 1968). Group P could be cured of vertiginous attacks by operating on the affected side. However, in group C a sympathectomy of both sides was required to prevent recurrence of the attacks. From the results and findings of this operation, it was thought that the vasomotor reflex had a close connection with the vertiginous attacks and that the effectiveness of this operation was due to the blocking of the efferent impulses which caused the vasospasms.

    A 3.5-year-old female Chihuahua was presented with complaint of neck pain, intermittent cough and dysphagia. Physical examination and diagnostic imaging of neck region revealed a solid and highly vascularized mass involving the retropharyngeal region. Histologically, the mass showed an atypical zellballen pattern which comprised of high density of type I chief cells with high nuclear cytoplasmic ratio and separated by delicate fibrovascular stroma. Immunoreactivity for neuroendocrine markers was diffusely positive in cytoplasm of tumor cells. Disseminated tumor emboli in external jugular vein were detected 6 months after initial surgery. An electron microscopic study revealed numerous electron-dense intracytoplasmic neurosecretory granules. Based on these findings, carotid body carcinoma was diagnosed.

    Introduction : The aim of the study was to investigate the association between the difference (defined as the remainder, Rm) in laboratory values determined in the upright and supine positions and the severity of obstructive sleep apnea syndrome (OSAS). Materials and Methods : Thirty-three Japanese male subjects with OSAS [apnea/hypopnea index (AHI: the number of apneas and hypopneas per hour) ≥ 5] underwent cephalometric analysis and measurements of nasal resistance in the upright and supine positions. Several parameters in a dental model and physical features were also analyzed. Results : Significant associations of the logarithmic AHI, with neck depth, Rm for the facial axis, and the minimum airway behind the tongue in the supine position were found in multiple linear regression analysis. Conclusion : Our results suggest that neck depth, Rm for the facial axis and the minimum airway behind the tongue in the supine position may be determinants of the severity of OSAS.

    Optokinetic stimuli were given to adult non-albino rabbits on alternate days and changes in optic eye and head nystagmus induced thereby were examined. The results were as follows:
    1) The eye nystagmus responses gradually increased after repeated optic training by optokinetic stimulation, so that the velocity of cylinder rotation for inducing nystagmus at the maximum frequency could be raised and the upper limit of cylinder rotation which effectively induced nystagmus was raised. Head nystagmus appeared at a higher velocity of cylinder rotation after training and continued on more rapid cylinder rotation.
    2) After the proprioceptors in either the deep or the superficial nuchal muscles had been inactivated by procainization, the animals were exposed to the same optic training. The phenomena described in 1) were seen less in these animals. This tendency seemed to be more evident in those rabbits in which the deep nuchal museles were procainized.

    As the recently developed medical treatments for asymptomatic cervical carotid artery stenosis (ACCAS) have shown excellent stroke prevention, carotid endarterectomy (CEA) should be carried out for more selected patients and with lower complication rates and better long-term outcomes. We have performed CEA for Japanese ACCAS patients with a uniform surgical technique and strict perioperative management. In this study, we retrospectively investigated the perioperative complications and long-term outcomes of our CEA series. A total of 147 CEAs were carried out in 139 Japanese ACCAS patients. All patients were routinely checked for their cardiac function and high risk coronary lesions were preferentially treated before CEA. All CEAs were performed under general anesthesia using a shunt system. The postoperative cerebral blood flow was routinely measured under continued sedation to prevent postoperative hyperperfusion. The 30-day perioperative morbidity rate was 2.04%, including a perioperative stroke rate of 0.68%. There were no perioperative deaths. With regard to the long-term outcomes of the 134 followed-up patients, 9 patients were dead and 5 patients suffered from strokes, including 2 patients with ipsilateral hemispheric ischemia. The annual rates of death, all stroke and ipsilateral ischemic stroke were 1.15%, 0.64%, and 0.25%, respectively. These results showed that the perioperative morbidity and mortality rates of our CEAs were lower than those in the previous large trials. Furthermore, the long-term outcomes of this series were favorable to those reported in the latest medical treatment trials for ACCAS patients. CEA may be useful for preventing ischemic stroke in Japanese ACCAS patients.

    Objective: We examined the usefulness of Doppler ultrasonography for the diagnosis of severe stenosis of the proximal vertebral artery (VA).

    Case Presentations: We performed Doppler ultrasonography of the VA in patients diagnosed with cerebral ischemia of the posterior circulation. Incorporating the diagnostic criteria for severe stenosis at the origin of the internal carotid artery (maximum peak systolic flow velocity: ≥200 cm/sec, or acceleration time: ≥110 msec), patients were screened for proximal VA stenosis and cerebral angiography was conducted if they fulfilled the above criteria. In all six patients in whom proximal VA stenosis was suspected on ultrasonography, angiography confirmed severe stenosis, and endovascular treatment was performed. In five patients who underwent postoperative ultrasonography, an improvement of the stenosis was confirmed.

    Conclusion: Doppler ultrasonography is useful for the screening and postoperative assessment of proximal VA stenosis.

    Purpose: We report a patient who underwent stenting for dissection related to internal-shunt insertion during carotid endarterectomy (CEA).

    Case Presentation: A 77-year-old female with a history of stenosis of the left carotid artery. During admission due to infectious enteritis, right hemiplegia occurred, and arteriogenic embolism was observed. After an improvement in the general condition was achieved, CEA was performed. Intimal thickening involving the periphery to the most stenotic site was noted. When inserting a shunt into the internal carotid artery, there was a resistance, and there was no blood flow regurgitation, suggesting iatrogenic dissection. After plaque removal and vascular suture, the patient was transferred to the angiography room while maintaining general anesthesia, and a stent was inserted to the site of dissection. Anterograde blood flow was achieved, and the postoperative course was favorable.

    Conclusion: Stenting for carotid artery dissection related to shunt insertion during CEA may be effective.

    Spinal subarachnoid hematoma (SSH) is a rare condition, more commonly occurring after lumbar puncture for diagnostic or anesthesiological procedures. It has also been observed after traumatic events, in patients under anticoagulation therapy or in case of arteriovenous malformation rupture. In a very small number of cases no causative agent can be identified and a diagnosis of spontaneous SSH is established. The lumbar and thoracic spine are the most frequently involved segments and only seven cases of cervical spine SSH have been described until now. Differential diagnosis between subdural and subarachnoid hematoma is complex because the common neuroradiological investigations, including a magnetic resonance imaging (MRI), are not enough sensitive to exactly define clot location. Actually, confirmation of the subarachnoid location of bleeding is obtained at surgery, which is necessary to resolve the fast and sometimes dramatic evolution of clinical symptoms. Nonetheless, there are occasional reports on successful conservative treatment of these lesions. We present a peculiar case of subarachnoid hematoma of the craniocervical junction, developing after the rupture of a right temporal lobe contusion within the adjacent arachnoidal spaces and the following clot migration along the right lateral aspect of the foramen magnum and the upper cervical spine, causing severe neurological impairment. After surgical removal of the hematoma, significant symptom improvement was observed.

    24 upper cervical spine injuries consist of 3 bursting atlantal fractures, 4 posterior arch fractures of atlas, 5 fractures of dens, 3 fractures of axis body, 2 hangman fractures, one vertebral arch fracture of dens and 6 atlanto-axial rotatory fixations.
    All bursting atlantal fractures were treated with skull traction and resulted in nonunion, but showed no instability and unremarkable symptomes.
    All atlanto-axial rotatory fixations belonged to type I in Fielding's classification and were successfully manipulated with or without anesthesia.
    Anterior dislocations of atlas associated with non union of dens fracture were possibly reduced with skull traction and were immobilized with posterior fusion from occiput to third cervical vertebra.
