Case ReportsDestructive Spondyloarthropathy due to Congenital Insensitivity to Pain with Anhidrosis: A Case Report of Long-Term Follow-up.
Congenital insensitivity to pain with anhidrosis (CIPA) is a rare autosomal-recessive hereditary neuropathy causing congenital loss of pain sensation, thermoception, and perspiration. CIPA sometimes causes destructive spondyloarthropathy, the so-called Charcot spine, because of insensitivity to pain stimuli. Herein, we report a case of CIPA with severe spinal destruction treated by multiple spinal reconstructive surgeries and over 15 years of follow-up. ⋯ Subsequently, a two-staged posterior and anterior fusion surgery from the lower thoracic spine to the pelvis was performed, and spinal fusion and neurological recovery were achieved 3 years after surgery. A kyphotic deformity in patients with CIPA-associated Charcot spine could be favorably treated by a long spinal fusion in combination with a reconstruction of an anterior spinal column. This case report provides a significant lesson for a treatment of CIPA-associated Charcot spine.

Identification of Novel Genes and Associated Drugs in Advanced Clear Cell Renal Cell Carcinoma by Bioinformatic Methods.
The current work screened differentially expressed genes (DEGs) related to advanced clear cell renal cell carcinoma (ccRCC) and found potential biomarkers and drugs for advanced ccRCC. After analyzing GSE53757 and GSE66271, we identified DEGs and performed the functional annotation, pathway enrichment, validation, survival analysis, and candidate drug analysis. We obtained 861 common DEGs from datasets between advanced ccRCC tissues and normal kidney tissues. ⋯ The gene-drug analysis showed that gallium nitrate, cladribine, and amonafide were strongly associated with RRM2 and TOP2A. We found that RRM2 and TOP2A might be predictive biomarkers and novel targeted therapy for advanced ccRCC. These drugs (gallium nitrate, cladribine, and amonafide) might be used for treating advanced ccRCC.

Effectiveness of Influenza Vaccination among Children in Satellite Cities of a Metropolitan Area in Tokyo, Japan during the 2014/2015-2018/2019 Season.
Influenza vaccination is recommended for children. In particular, those aged 6 months to 12 years were recommended two vaccinations in Japan, whereas the recommended year range for the twice vaccination is 6 months to 8 years by the World Health Organization (WHO). This study assessed the effectiveness of influenza vaccination and whether the twice vaccinations enhanced preventive effects against influenza infection among children living in two satellite cities of a metropolitan area in Tokyo, Japan. ⋯ The AOR of influenza for pre, grade 1 elementary, and grade 2 schoolchildren who received two vaccinations was 0.63 (95% CI, 0.59-0.69), 0.75 (0.67-0.83), and 0.81 (0.71-0.92), respectively, when compared to those without vaccination. However, no trend in vaccinations and their effectiveness was observed in the third and higher-grade school children. Our findings support the recommendation by the WHO, and could help guide influenza vaccination policies for children in Japan.

Case ReportsCOVID-19 in a Hairy Cell Leukemia Patient: A Rare Case Report.
The detailed clinical course of coronavirus disease 2019 (COVID-19) in patients with hairy cell leukemia (HCL) is rarely reported. We report the first case of HCL diagnosed with prolonged pancytopenia after COVID-19 infection in Japan. We describe the case of a 56-year-old man who was diagnosed with COVID-19. ⋯ Further, the condition of all previously reported patients with COVID-19 associated with HCL was severe enough to require mechanical ventilation. This is the first case in which the disease was not severe. The interleukin-6 (IL-6) level was lower in this case than in previous cases, suggesting that racial differences in IL-6 production may have contributed to COVID-19 severity.

Long-term voice abuse or sudden vocal fold microvascular disruption may lead to injury and subsequent repair/remodeling in the vocal fold mucosa. Periostin is known to be involved in airway remodeling and also in various otolaryngological diseases. The aim of this article was to investigate the expression and the role of periostin in the formation of vocal fold polyps. ⋯ The infiltrative pattern of periostin expression was significantly dominant in vascular-hyaline types. Expression of transforming growth factor-β (TGF-β) was also detected in the vocal fold polyps. Our results confirmed that periostin might be involved in certain pathological changes in vocal fold polyps, such as extracellular matrix accumulation, local fibrosis, and formation and development of vocal fold polyps.
