A 59-year-old woman has presented symptoms of fatigue since January 1996. Atypical coarctation due to aortitis syndrome had been diagnosed 8 years earlier. Her upper-limb blood pressure was 200mmHg and antihypertensive drugs were administered. An aortogram showed severe stenoses of the aorta at the level of the diaphragm and renal artery. A computed tomogram showed extensive calcification of the aorta below the origin of the left subclavian artery. She underwent a bypass operation with a 16-mm-diameter prosthetic graft from the ascending aorta to the infrarenal abdominal aorta. She has progressed well after the bypass and her upper-limb blood pressure is almost normal.

We studied the effect of Saiko-ka-ryukotsu-borei-to (crude extract powder for research purposes) on central monoamine-related substances in mice. The formulation was given in a dose of 50mg/kg or 400mg/kg and was administered once or repeatedly (twice a day for seven days). The brain was removed and segmented in the conventional method. The monoamine-related substances were measured by a method using HPLC-ECD. The main results were as follows. The single or repeated administration of 50mg/kg increased DOPAC and HVA contents in the cerebral cortex. In the hypothalamus, the single 50mg/kg treatment decreased NE, and the repeated 50mg/kg treatment decreased NE but increased DOPA. In the corpus striatum, the single 50mg/kg administration increased DA, DOPAC, HVA, and 5-HIAA while the repeated administration increased NE and MHPG as well. In this region, the single 400mg/kg treatment increased NE and 5-HIAA, and the repeated treatment increased NE. In the hyppocampus, the repeated 50mg/kg treatment increased MHPG, and the repeated 400mg/kg treatment decreased HVA. These results indicate that the effect of this formulation on murine brain monoamines is greater at 50mg/kg than at 400mg/kg and that the effect varies among the regions of the brain.

Intestinal spirochetosis is a rare gastrointestinal infection caused by Brachyspira. Clinical manifestations vary, ranging from asymptomatic infection to gastrointestinal bleeding, diarrhea, or abdominal pain. Antimicrobial medications such as metronidazole are routinely given, but their clinical efficacy has not determined with any precision. We report a case of intestinal spirochetosis treated with daikenchuto extract with literature reviews. Treatment of intestinal spirochetosis can be difficult, and use of daikenchuto extract may be an option especially for patients with symptoms such as chronic diarrhea, abdominal distention, or change in flatus.

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.

Asian Spine Journal 2022;16(1):47-55
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.
