To investigate the effect of electro-acupuncture stimulation (EAS) on insulin sensitivity in rats, we performed several stimulations on Otsuka Long Evans Tokushima Fatty (OLETF) rats, during euglycemic clamp. We divided OLETF rats into five groups according to the kind of the stimulation: EAS at vagal innervated region of the auricle (AVA), EAS at non-vagal innervated region of the auricle (ANVA), EAS on the back of the body (AB), pinching on the back of the body (PB), and no stimulation on the body (NS). These procedures were also applied on Long Evans Tokushima Otsuka (LETO) rats as a control study.
Furthermore, we performed long-term stimulation (from six to 24 weeks of age) on OLETF rats to assess the preventive effect of those stimulations on the formation of the insulin resistance. EAS of pulse duration 300ms, 1.5V, 1Hz was applied for 10 or 15minutes. As a result, the glucose infusion rate (GIR) showed significantly higher levels during stimulation of PB group in LETO rats. On the other hand, the GIR of AVA group in LETO rats and PB group in OLETF rats were decreased by stimulation. The GIR in AVA group and AB group after long-term stimulation were significantly higher than those of NS group in OLETF rats. These results suggested that EAS at the auricle and the back is useful for the prevention of the formation of insulin resistance when it's applied before onset of the symptoms in OLETF rats.

Destructive spondyloarthropathy (DSA) has been reported in patients undergoing long-term hemodialysis. Cervical spinal lesions, including those of the upper cervical spine, are reported to be some of the most common. To our knowledge, we report for the first time, a case of atlanto-occipital subluxation requiring surgical treatment due to severe myelopathy and nuchal pain in a patient undergoing long-term hemodialysis. The patient was a 66-year-old woman who had undergone hemodialysis for 40 years. She visited our hospital due to an acute progression of gait disturbance and severe nuchal pain. Computed tomography showed posterior subluxation of the atlanto-occipital joints. DSA was also observed in the lower cervical spine. Magnetic resonance imaging showed spinal canal stenosis at both the upper and lower cervical levels. We performed Oc-C7 fixation, C1 laminectomy, and C3-C7 laminoplasty. We first recognized that the atlanto-occipital subluxation was caused by the extremely long-term, in this case, 40 years, hemodialysis.

The purpose of this study was to investigate the causes of failure to return to the pre-fracture place of residence at hospital discharge following an operation for a hip fracture and to continue medical treatment for osteoporosis. Herein, we discuss methods for improving discharge protocols for these patients. We examined patients who sustained osteoporotic fractures and were operated on for a hip fracture between 2001 and 2003 (83 males and 386 females; 81.2 ± 9.0 years old) and between 2011 and 2013 (121 males and 462 females; 83.1 ± 9.3 years old). In a follow-up study, we examined patients who moved into our related rehabilitation institution over a 3-year period, from 2011 to 2013. The incidence of hip fractures had increased from 2001-2003 to 2011-2013 in both genders, and it tended to increase in patients greater than 80 years of age in male and 90 years of age in female. The most common destination residence after discharge from the rehabilitation institution was the pre-fracture place of residence. The Barthel Index at discharge from the rehabilitation institution was significantly lager in patients who returned to the pre-fracture place of residence compared to those who returned to nursing home and our hospital. These results suggest improved mobility and ADL level of patients enable them to return to the pre-fracture place of residence. We propose the construction of a feedback system that aids in a medical pass to increase the ambulant consultation rate for orthopedics and prevent fragile fractures.

STUDY DESIGN: A retrospective study. PURPOSE: To investigate the surgical outcome for hemodialysis-related upper cervical lesions. OVERVIEW OF LITERATURE: Surgical outcome of lower cervical lesions in patients undergoing hemodialysis has been reported. However, surgical outcome for upper cervical lesions in hemodialysis patients is unclear. METHODS: Upper cervical lesions in nine patients undergoing hemodialysis were surgically treated. Mean age at surgery was 61.6 years (range, 52-68 years), and the mean follow-up period was 45.4 months (range, 2-98 months). Patients had undergone hemodialysis for an average of 25.3 years (range, 16-40 years) at surgery. Seven patients with destructive spondyloarthropathy (DSA) of the upper cervical spine were treated with atlantoaxial or occipitocervical fixation. Two patients with retro-odontoid pseudotumors were treated with C1 posterior arch resection alone. Japanese Orthopedic Association (JOA) scores for cervical myelopathy, postoperative complications, postoperative radiography, and preoperative and postoperative occipital pain were evaluated. RESULTS: Mean preoperative and postoperative JOA score was 3.7 and 8.1, respectively. The seven patients with DSA had severe preoperative occipital pain that disappeared postoperatively. Postoperative radiography showed solid bone union in DSA cases and no instability in pseudotumor cases. CONCLUSIONS: Satisfactory surgical outcome was observed for hemodialysis-related upper cervical lesions.

The present study investigated the effect of moxibustion for 4 weeks on insulin resistance in Otsuka-Long-Evans Tokushima Fatty (OLETF) rats, a model of spontaneous noninsulin-dependent diabetes mellitus (NIDDM). Glucose infusion rate (GIR) in the moxibustion group was higher than that in the control group. This finding suggests that moxibustion may be effective for insulin resistance.

The purpose of this study is to investigate the prevalence of and to classify the types of silicosis patients who were working at that time as migrant workers in the eastern part of Toyama Prefecture. Migrant workers are known in Japanese as “dekasegi” This term refers to workers who migrate seasonally from their home towns to areas where work is more available.
Questionnaires were sent to all male inhabitants aged 30 or over in the selected five areas. Eighty-seven percent of the questionnaires were answered and returned. Based on the results, 482 inhabitants were selected as migrant workers with experience in jobs where they were exposed to large amount of dust. Chest roentgenography and subjective symptoms were examined in these subjects.
The results obtained were follows;
(1) Eight hundred and eighty-five of the respondents (41%) had worked as migrant workers.Of these, 580 men (66%) had worked in jobs with exposure to dust.
(2) Of the 482 migrant workers whose jobs exposed them to dust, 424 silicosis cases (88%) were found by chest roentgenographic examination. Silicosis is classified into four types according to the national Pneumoconiosis Law on the basis of chest roentgenographic findings. These patients included 195 cases of type 1, 123 cases of type 2, 59 cases of type 3 and 47 cases of type 4 silicosis.
(3) The prevalence of disease symptoms in the silicosis patients included ; cough 39%, phlegm 40%, shortness of breath 41%, palpitations 17% and wheezing in 20% of the cases. The silicosis patients showed a higher frequency of respiratory disease symptoms than those dust-exposed workers who did not evidence signs of silicosis.
(4) The silicosis patients were found in 98% of the migrant workers whose exposure to dust lasted a period of more than 20 years, 89% in men whose work was between 10 and 19 years and 76 % in men who had worked less than 10 years.
(5) The silicosis in 297 cases (70% of the total number of disease patients) was first detected during the examinations in the course of this research.

[Background]Functional abdominal pain syndrome (FAPS) represents a chronic pain disorder localized in the abdomen and the symptoms largely are unrelated to food intake and defecation, which differ from other painful functional gastrointestinal disorders.
We report a case of FAPS whose symptom was successfully improved by acupuncture.
[Case Report]A 75-year-old female had been hospitalized at Meiji University of Integrative Medicine Hospital because of left lower abdominal pain from which she had repeatedly suffered for more than 2 years. Despite strict medication, her symptom had not been improved. After admission to the hospital, according to recommendation by her physician, acupuncture treatment was started. The patient received TCM-based acupuncture treatments five times a week over 13weeks. Primary acupuncture points used for the patient were LV3(Taichong), SP6 (Sanyinjiao), ST36 (Zusanli) and PC6 (Neiguan). Evaluation of the left lower abdominal pain was carried out with a Visual Analogue Scale (VAS). The Gastrointestinal Symptom Rating Scale (GSRS) was used to evaluate QOL related to the digestive symptoms. VAS for the left lower abdominal pain showed a remarkable decrease immediately after the initial acupuncture session. The symptom disappeared within 4 weeks after commencement of the treatment and never appeared during her hospitalization. GSRS was also improved and it was maintained during hospitalization.
[Conclusion]We suggested that acupuncture treatment might be one of the useful, non-pharmacological alternatives for symptoms of FAPS.

STUDY DESIGN: A retrospective study. PURPOSE: To clarify the features useful for the differential diagnosis of spinal canal tumoral lesions in patients undergoing hemodialysis. OVERVIEW OF LITERATURE: Tumoral lesions in the spinal canal are rarely found in hemodialysis patients. Therefore, the differential diagnosis of tumoral lesions in the spinal canal in hemodialysis patients has been very difficult. METHODS: Spinal canal tumors in 17 patients undergoing hemodialysis or continuous ambulatory peritoneal dialysis were investigated. Histopathological analysis was conducted for all specimens obtained during surgery. The tumoral lesions were categorized into 3 groups on the basis of histopathology: spinal cord tumor, amyloidoma, and other. Patient medical history and diagnostic images of each group were reviewed. RESULTS: Eight of 17 cases were histopathologically diagnosed as spinal cord tumors and were neurinomas, 6 were amyloidomas, and 3 were classified as other. The rate of spinal cord tumors was 47.1% (8 of 17 cases), which revealed the most frequent lesion type. The rate of amyloidomas and other types was 35.3% (6 of 17 cases) and 17.6% (3 of 17cases), respectively. In the amyloidoma group, the mean duration of hemodialysis (24.3 years) was longer than that of spinal cord tumors and other types (9.2 years and 8.6 years, respectively). All spinal cord tumors were intradural extramedullary, whereas all amyloidomas and other types were extradural. CONCLUSIONS: The rate of each tumoral lesion, the duration of hemodialysis, and the tumoral localization are important features for the differential diagnosis of tumoral lesions in the spinal canal in hemodialysis patients.

OBJECTIVES: This is an open labeled and retrospective cohort study which compared the effectiveness and safety of ibandronate (IBN) and minodronate (MIN) combined with eldecalcitol (ELD) in primary osteoporosis of women. METHODS: One hundred and forty-eight primary osteoporotic women were classified into 3 groups; 1) intravenous IBN combined with oral ELD (IBN + ELD group, N = 50; 81.8 ± 6.2 years), 2) oral MIN combined with oral ELD (MIN + ELD group, N = 50; 77.2 ± 6.9 years) and 3) oral ELD alone (ELD group, N = 48; 75.0 ± 8.3 years). For statistical analysis, L-BMD, H-BMD, serum corrected Ca, serum iP, intact-PTH, TRACP-5b, BAP, serum Hcy, eGFR and urine Ca/Cr ratio were measured until 12 months after the start of therapy. RESULTS: L-BMD values increased significantly in both IBN + ELD and MIN + ELD group, however, H-BMD increased significantly in the IBN + ELD group only. TRACP-5b values decreased rapidly during the first 6 months in both IBN + ELD and MIN + ELD group. However, BAP value in the IBN + ELD group decreased more gradually compared with that in the MIN + ELD group. Both serum Ca value and urine Ca/Cr ratio tended to increase, and the eGFR value decreased significantly in each group. CONCLUSIONS: IBN combined with ELD administration can act more effectively to increase BMD compared with MIN combined with ELD administration. Differences of decreasing rate in TRACP-5b and BAP value may lead to differences of increased rate of BMD in the IBN + ELD and MIN + ELD group. Because many cases of osteoporosis are elderly persons associated with chronic kidney disease, monitoring of kidney function and concentration of Ca in blood and urine is essential.

Pycnodysostosis is an autosomal recessive disorder characterized by osteosclerosis, small stature, acro-osteolysis of the distal phalanges, loss of the mandibular angle, separated cranial sutures with open fontanels, and frequent fractures. One identified cause of the disease is reduced activity of the cysteine protease cathepsin K. A 48-year-old woman with a history of frequent fractures presented with a severe gait disturbance. Radiography, computed tomography, magnetic resonance imaging, and gene analysis were performed. Physical examination revealed open fontanels, and radiographs showed increased bone density. DNA sequence analysis revealed a deletion mutation of the cathepsin K gene. We diagnosed pycnodysostosis based on these findings. The magnetic resonance and computed tomography images demonstrated multilevel spinal canal stenosis due to ossification of the yellow ligament. We performed a laminectomy, and the patient's neurological signs and symptoms improved. To our knowledge, this is the first case of pycnodysostosis with ossification of the yellow ligament.
