Methods: This study included 99 men (mean age, 74.9 years; range, 28–93 years) who visited Qiball Clinic for BMD and body composition examinations. The osteoporosis group consisted of 24 patients (mean age, 72.5 years; range, 44–92 years), and the control group consisted of 75 individuals (mean age, 74.9 years; range, 28–93 years). Whole-body skeletal muscle mass was measured using a bioelectrical impedance analyzer. BMD was measured by dual X-ray absorptiometry. Skin autofluorescence (SAF), a marker of dermal AGE accumulation, was measured using a spectroscope. Osteoporosis was defined as a bone density T score of –2.5 or less. Physical findings, skeletal muscle mass, BMD, grip strength, and SAF were compared between the osteoporosis and control groups. Results: The osteoporosis group had significantly lower trunk muscle mass (23.1 kg vs. 24.9 kg), lower leg muscle mass (14.4 kg vs. 13.0 kg), and skeletal mass index (7.1 kg/m2 vs. 6.7 kg/m2) than the control group (all p<0.05). Lower limb muscle mass was identified as a risk factor for osteoporosis in men (odds ratio, 0.64; p=0.03). Conclusions Conservative treatment of osteoporosis in men will require an effective approach that facilitates the maintenance or strengthening of skeletal muscle mass, including exercise therapy with a focus on lower extremities and nutritional supplementation.

Methods: A total of 14 patients with unilateral radicular symptoms and five healthy subjects were subjected to simultaneous apparent T2 mapping and neurography with nerve-sheath signal increased with inked rest-tissue rapid acquisition of relaxation enhancement signaling (SHINKEI-Quant) using a 3-Tesla magnetic resonance imaging. The Visual Analog Scale (VAS) score for neck pain and upper arm pain was used to evaluate clinical symptoms. T2 relaxation times of the cervical dorsal root ganglia of the brachial plexus were measured bilaterally from C4 to C8 in patients with radicular symptoms and from C5 to C8 in healthy controls. The T2 ratio was calculated as the affected side to unaffected side. Results: When comparing nerve roots bilaterally at each spinal level, no significant differences in T2 relaxation times were found between patients and healthy subjects. However, T2 relaxation times of nerve roots in the patients with unilateral radicular symptoms were significantly prolonged on the involved side compared with the uninvolved side (p<0.05). The VAS score for upper arm pain was not significantly correlated with the T2 relaxation times, but was positively correlated with the T2 ratio. Conclusions In patients with cervical radiculopathy, the SHINKEI-Quant technique can be used to quantitatively evaluate the compressed cervical nerve roots. The VAS score for upper arm pain was positively correlated with the T2 ratio. This suggests that the SHINKEI-Quant is a potential tool for the diagnosis of cervical nerve entrapment.

Purpose: In this multicenter retrospective observational study, we examined the early effects of romosozumab in patients with severe osteoporosis in terms of time-course changes in bone metabolism marker, improvement in bone density, and adverse effects. Materials and Methods: Patients with severe osteoporosis were included. We investigated the progress of TRACP 5b and P1NP before and 1–2 months after the administration of romosozumab. We also investigated the bone density of lumbar spine, femoral neck, and the entire femur, measured by the DXA method, before and 5–7 months after the administration of romosozumab. Results: A total of 70 patients (7 males and 63 females, age 75.0±3.6 years) participated in this study. Significant improvements in TRACP 5b and P1NP levels were observed before and 1–2 months after romosozumab administration. The average bone density of lumbar spine, femoral neck, and the entire femur were measured before and 5–7 months after romosozumab administration;and a significant increase only observed in the lumbar spine. Conclusion Consistent with the findings of previous clinical studies, romosozumab has both bone formation-enhancing and bone resorption effects (dual effect). In addition, romosozumab also demonstrated improvement in bone density from the early phase after the administration, though the result was only seen in the lumbar spine.

The diagnosis of pituitary carcinoma cannot be made easily histologically, and most cases of pituitary carcinoma are diagnosed only after the clinical detection of metastasis. Distant metastasis of pituitary tumor occurs in 0.1% to 0.2% of cases and has been reported in the liver, bone and central nervous system, with only one case of metastasis to the cauda equine reported. This study describes a rare case of the drop metastasis of adrenocorticotropic hormone-producing pituitary adenocarcinoma to the cauda equina, causing cauda equina syndrome.

　　Case I was a 85-year-old woman. She was referred to us as her serum CEA level was found as high as 9.2ng/ml at a clinic in her neighborhood. CT and ultrasound scans revealed a cystic tumor in the appendix area. A barium enema examination showed a tubercular lesion in the subcecal area. The surface of the lesion was flat and smooth. The vermiform appendix was not scanned with the contrast medium.　　She was diagnosed with mucinous cystadenoma of the appendix. Partial cecotomy was performed. The postoperative serum CEA fell to a normal level of 4.7ng/ml.　　Case II was also a woman . The 74- year-old inpatient was being treated for high blood pressure and hyperlipemia when her serum CEA level was found elevated to 12.3ng/ml. CT and ultrasonograph examinations revealed a cystic tumor in the appendix area. A barium enema examination showed a mucocele-like tubercle in the appendix. The patient was diagnosed with mucinous cystadenoma of the appendix and partial cecotomy was performed. The CEA level was normalized postoperatively with 1.5ng/ml.　　The pathologic tests confirmed either of these two cases was mucinous cystadenoma of the appendix. Immunohistochemical staining showed a CEA positive.

This report takes up a 65-year-old woman. Suspecting a tumorous superior fovea in the left clavicle, she consulted with our hospital’s Department of Otolaryngology. As a result of the lymph node biopsy performed at the department, she was diagnosed as having moderately differentiated tubular carcinoma. CT scanning revealed a number of swollen lymph nodes and parietal tylosis in the sigmoid colon. Endoscopy produced no abnormalities in the upper digestive tract, but an endoscopic check of the lower digestive tract revealed an all-around Type II tumor. The ailment was pathohistologically identified as tubular carcinoma. That said, the patient was diagnosed as suffering from sigmoid colon accompanying Virchow lymph node metastasis. Then, sigmoidostomy and the dissection of the D3 lymph node were performed. Pathohistological diagnosis revealed moderately differentiated tubular carcinoma, SE, N3, HO, PO, M1 (Virchow lymph node metastasis), Stage IV. Chemotherapy was postoperatively initiated with mFOLFOX6.

  A 86-year-old woman visited us, complaining about sharp abdominal pain she had very morning when she got up. Ultrasound and computer tomography scans of the abdomen revealed notable parietal hypertrophy and swelling of the gallbladder. The old woman was diagnosed with acute cholecystitis and immediately admitted to the hospital. Her condition did not improve on conservative management. Percutaneous transhepatic gallbladder drainage (PTGBD) was performed. The bile thus aspirated was bloody, which led us to suspect necrotizing cholecystitis. Emergency cholecystectomy was done. The abdominal operation found the gallbladder wandering with a torsion of 360 degrees around the gallbladder neck as the axis and the leakage of bile in the abdominal cavity from what could be presumed to be the area where the PTGBD was placed. After the torsion was corrected, the gallbladder was surgically removed. Neither gallstones nor tumors were found in it. There were signs of hemorrhagic necrosis in the mucus membrane. The patient made good progress after the operation and was discharged on the 15th hospital day. Torsion of the gallbladder is a comparatively rare entity and its symptoms are not always specific. Therefore, it defies preoperative diagnosis. In this paper, we report our experience with a case of this disease which presented characteristic radiographic images and discuss the treatment strategies including PTGBD.

We simulated mountain climbing using walking on a treadmill in order to systematically evaluate the physical load during mountain climbing. The conditions of three types of load-(1) inclination of the walking path (walking uphill and downhill), (2) walking speed, and (3) backpack weight-were varied within the range assumed for normal mountain climbing (40 sets of conditions in total). When the three types of load were expressed as vertical work rate, energy expenditure (VO₂) during walking uphill and downhill was distributed along roughly the same curve. The following characteristics of walking uphill and downhill were observed.A. Walking uphillFor all three types of load, increase in load gave a linear increase in VO₂ and heart rate (HR). A lactate threshold (LT) appeared at an intensity of 62%VO_2max, when HR was 78% HR_max. Rating of perceived exertion (RPE) was evaluated for the “Breathlessness” and “Leg Fatigue”, and both of these increased roughly in proportion to %VO_2max.B. Walking downhillWhen walking downhill, VO₂ was 35-50% the intensity of VO₂ when walking uphill on the same slope and at the same speed. Energy expenditure did not exceed 60%VO_2max in any of the load conditions, and no LT was seen. RPE values were higher for walking downhill than walking uphill, even when %VO_2max values were the same. RPE values for the “Leg Fatigue” tended to be higher than for the “Breathlessness” at the same speed in downhill walking.Using these data, we created a table giving the intensity of exercise of mountain climbing expressed as VO₂ per unit body mass and metabolic equivalents (Mets) with vertical migration velocity and total weight (Body weight + Backpack weight) as variables. This table gives mountain climbers a systematic understanding of the physical load under various mountain climbing conditions. It is likely to be of use as a reference for mountain climbers of different levels of physical fitness when practicing mountain climbing appropriate to their individual level. The present results suggest that in downhill walking, it is insufficient to express the physical load in energy expenditure (VO₂ and Mets) alone, and the load on the leg muscles must also be judged using the RPE in the “Leg Fatigue”.

BACKGROUND: Epidural anesthesia is widely used to provide pain relief, whether for surgical anesthesia, postoperative analgesia, treatment of chronic pain, or to facilitate painless childbirth. In many cases, however, the epidural catheter is inserted blindly and the indwelling catheter position is almost always uncertain. METHODS: In this study, the loss-of-resistance technique was used and an imaging agent was injected through the indwelling epidural anesthesia catheter to confirm the position of its tip and examine the migration rate. Study subjects were patients scheduled to undergo surgery using general anesthesia combined with epidural anesthesia. Placement of the epidural catheter was confirmed postoperatively by injection of an imaging agent and X-ray imaging. RESULTS: The indwelling epidural catheter was placed between upper thoracic vertebrae (n = 83; incorrect placement, n = 5), lower thoracic vertebrae (n = 123; incorrect placement, n = 5), and lower thoracic vertebra-lumbar vertebra (n = 46; incorrect placement, n = 7). In this study, a relatively high frequency of incorrectly placed epidural catheters using the loss-of-resistance technique was observed, and it was found that incorrect catheter placement resulted in inadequate analgesia during surgery. CONCLUSIONS: Although the loss-of-resistance technique is easy and convenient as a method for epidural catheter placement, it frequently results in inadequate placement of epidural catheters. Care should be taken when performing this procedure.
