Objective: Almost half of all patients with cancer experience dyspnea, which can have various causes. Although systemic corticosteroids are administered to relieve symptoms, their efficacy has not been established. This systematic review aims to determine the efficacy of systemic corticosteroids for dyspnea in patients with cancer. Methods: CENTRAL, MEDLINE, EMBASE, and Ichushi-Web databases were searched for articles published from their inception to September 23, 2019, on studies of systemic corticosteroid administration for dyspnea in patients with cancer. The primary outcome measure was dyspnea intensity, as assessed by patient-reported outcomes. Secondary outcome measures were quality of life, delirium, and severe adverse events. Results: Two RCTs were included in the meta-analysis. With regard to alleviating dyspnea, the systematic corticosteroid group was associated with significantly greater dyspnea relief than the placebo group (mean difference: −0.71 [95% CI: −1.4 to −0.03]). However, a meta-analysis of quality of life and delirium could not be performed due to insufficient data. Analysis of severe adverse events showed no significant difference in their incidence between the corticosteroid and control groups (relative rate: 0.96 [95% CI: 0.19-4.93]). Conclusions: Systemic corticosteroids may be effective in treating dyspnea in patients with cancer, particularly those with lung involvement. Limiting the conditions for which corticosteroids are approved is expected to promote their appropriate use and minimize their adverse effects. However, further investigation is needed to determine the appropriate dosage, and the conditions in which corticosteroids are effective.

Methods:
This prospective, single-arm study included 11 patients (eight men; mean age, 62.7 years) with ≥3-months’ chronic pain history due to lumbar disease. Subcutaneous TCZ injections were administered twice, at a 2-week interval. We evaluated low back pain, leg pain, and leg numbness using numeric rating scales and the Oswestry Disability Index (ODI; baseline and 6 months postinjection); serum IL-6 and tumor necrosis factor-α levels (baseline and 1 month postinjection); and clinical adverse events.
Results:
Intractable symptoms reduced after TCZ administration. Low back pain improved for 6 months. Improvements in leg pain and numbness peaked at 4 and 1 month, respectively. Improvements in ODI were significant at 1 month and peaked at 4 months. Serum IL-6 was increased at 1 month. IL-6 responders (i.e., patients with IL-6 increases >10 pg/mL) showed particularly significant improvements in leg pain at 2 weeks, 1 month, and 2 months compared with nonresponders. We observed no apparent adverse events.
Conclusions
Systemic TCZ administration improved symptoms effectively for 6 months, with peak improvements at 1–4 months and no adverse events. Changing serum IL-6 levels correlated with leg pain improvements; further studies are warranted to elucidate the mechanistic connections between lumbar disorders and inflammatory cytokines.

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.

Methods:
Study participants comprised five healthy volunteers (mean age, 27.2 years) and 27 patients with LSS (mean age, 58.4 years) who were individually assessed using 3.0 Tesla magnetic resonance imaging. Intraspinal ADC and FA values of 10 intervertebral discs from healthy volunteers and 52 intervertebral discs from LSS patients were measured. Also, intraspinal canal area, Schizas classification (A: normal, B: mild stenosis, C: severe stenosis) and correlations with symptoms were investigated. Clinical symptoms were checked for the presence of low back pain (LBP), intermittent claudication (IMC), and bladder and bowel dysfunction (BBD).
Results:
Compared to healthy individuals, LSS patients had significantly lower ADC (

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.

Background/Aims:
There are few published registry studies from Asia on pediatric inflammatory bowel disease (IBD). Registry network data enable comparisons among ethnic groups. This study examined the characteristics of IBD in Japanese children and compared them with those in European children.
Methods:
This was a cross-sectional multicenter registry study of newly diagnosed Japanese pediatric IBD patients. The Paris classification was used to categorize IBD features, and results were compared with published EUROKIDS data.
Results:
A total of 265 pediatric IBD patients were initially registered, with 22 later excluded for having incomplete demographic data. For the analysis, 91 Crohn’s disease (CD), 146 ulcerative colitis (UC), and 6 IBD-unclassified cases were eligible. For age at diagnosis, 20.9% of CD, 21.9% of UC, and 83.3% of IBD-unclassified cases were diagnosed before age 10 years. For CD location, 18.7%, 13.2%, 64.8%, 47.3%, and 20.9% were classified as involving L1 (ileocecum), L2 (colon), L3 (ileocolon), L4a (esophagus/stomach/duodenum), and L4b (jejunum/proximal ileum), respectively. For UC extent, 76% were classified as E4 (pancolitis). For CD behavior, B1 (non-stricturingon-penetrating), B2 (stricturing), B3 (penetrating), and B2B3 were seen in 83.5%, 11.0%, 3.3%, and 2.2%, respectively. A comparison between Japanese and European children showed less L2 involvement (13.2% vs. 27.3%, P< 0.01) but more L4a (47.3% vs. 29.6%, P< 0.01) and L3 (64.8% vs. 52.7%, P< 0.05) involvement in Japanese CD children. Pediatric perianal CD was more prevalent in Japanese children (34.1% vs. 9.7%, P< 0.01).
Conclusions
Upper gastrointestinal and perianal CD lesions are more common in Japanese children than in European children.

STUDY DESIGN: A retrospective observational study was performed. PURPOSE: We investigated the prevalence of sarcopenia in dropped head syndrome (DHS), and the relationship between biochemical markers, including major advanced glycation end products (AGEs), pentosidine, and DHS in older women. OVERVIEW OF LITERATURE: AGEs have been implicated in the pathogenesis of sarcopenia. METHODS: We studied 13 elderly women with idiopathic DHS (mean age, 77.2 years) and 20 healthy volunteers (mean age, 74.8 years). We used a bioelectrical impedance analyzer to analyze body composition, including appendicular skeletal muscle mass index (SMI; appendicular lean mass [kg]/[height (m)]2). Cervical sagittal plane alignment, including C2–C7 sagittal vertical axis (C2–C7SVA), C2–C7 angle, and C2 slope (C2S), was measured. Biochemical markers, such as serum and urinary pentosidine, serum homocysteine, 1, 25-dihydroxyvitamin D, and 25-hydroxyvitamin D, were measured. The level of each variable was compared between DHS and controls. The relationship between biochemical markers and DHS was examined. RESULTS: Sarcopenia (SMI < 5.75) was observed at a high prevalence in participants with DHS (77% compared to 22% of healthy controls). Height, weight, femoral bone mineral density, appendicular lean mass, total lean mass, and SMI all had significantly lower values in the DHS group. Serum and urinary pentosidine, and serum homocysteine were significantly higher in the DHS group compared to controls. Analysis of cervical alignment revealed a significant positive correlation of serum pentosidine with C2–C7SVA and C2S. CONCLUSIONS: Sarcopenia was involved in DHS, and high serum pentosidine levels are associated with severity of DHS in older women.
