Observational Study
Can a relatively large spinal cord for the dural sac influence severity of paralysis in elderly patients with cervical spinal cord injury caused by minor trauma?
Retrospective reviewThe degree of spinal cord compression and bony spinal canal stenosis are risk factors for the occurrence of spinal cord injury (SCI) without major fracture or dislocation, but they do not affect the severity of neurological symptoms. However, whether a relatively large spinal cord for the dural sac influences the severity of symptoms in SCI cases is unknown. The purpose of this study was to verify the influence of spinal cord size relative to dural sac on the severity of paralysis in elderly patients with cervical SCI caused by minor trauma. ⋯ No clear relationship was observed between JOA score and bony canal APD or spinal cord compression ratio. In elderly patients with SCI caused by minor trauma, a relatively large spinal cord for the dural sac was shown to be a factor that influences the severity of paralysis. This result can be useful for the treatment and prevention of SCI in the elderly.

Pulmonary amyloidosis is a rare respiratory disease characterized by amyloid deposition in the lungs. The clinical manifestations of pulmonary amyloidosis are variable and without specific symptoms. ⋯ This case clearly shows that it is difficult to distinguish tracheobronchial amyloidosis from other diseases with manifestations of cough, dyspnea and chest tightness because of their similar symptoms and imaging findings. Thus, the role of transbronchoscopic lung biopsy and histological examination in the diagnosis of tracheobronchial amyloidosis is very important.

Review Case Reports
Primary pulmonary extranodal natural killer/T-cell lymphoma (ENKTL), nasal type: Two case reports and literature review.
Extranodal natural killer/T-cell lymphoma (ENKTL) - nasal type is an aggressive form of malignant non-Hodgkin lymphoma with a very poor prognosis. Especially primary pulmonary ENKTL is a relatively rare form of non-Hodgkin lymphoma. Until now, the prevalence of primary pulmonary ENKTL is unknown. Since 2001, only 18 cases of primary pulmonary ENKTL have been published, in addition to the 2 cases reported here. ⋯ The diagnosis of ENKTL should be considered when patients present with fever and expansile consolidation of the lung not responding to antibiotics. The diagnosis depends on histopathology and immunophenotyping. Percutaneous transthoracic needle biopsy is a safe and effective biopsy method. Chemotherapy may improve the prognosis, but this should be confirmed by prospective multicenter studies.

Meta Analysis
Cumulative evidence of relationships between multiple variants in 8q24 region and cancer incidence.
Genome-wide association studies (GWAS) have identified multiple independent cancer susceptibility loci at chromosome 8q24. We aimed to evaluate the associations between variants in the 8q24 region and cancer susceptibility. A comprehensive research synopsis and meta-analysis was performed to evaluate associations between 28 variants in 8q24 and risk of 7 cancers using data from 103 eligible articles totaling 146,932 cancer cases and 219,724 controls. ⋯ Data from ENCODE suggested that these variants with strong evidence and other correlated variants might fall within putative functional regions. Our study provides summary evidence that common variants in the 8q24 are associated with risk of multiple cancers in this large-scale research synopsis and meta-analysis. Further studies are needed to explore the mechanisms underlying variants in the 8q24 involved in various human cancers.

Review Case Reports
Spontaneous subepithelial hemorrhage of renal pelvis and ureter (Antopol-Goldman lesion) in hemophilia A patient with inhibitor: Case report and review of the literature.
The Antopol-Goldman lesion (AGL), which expresses subepithelial hemorrhage in the renal pelvis, was first defined by Antopol and Goldman in 1948. The objective of this study is to report the first case of AGL in patients with congenital hemophilia and review the relevant literature. ⋯ Although very rare, AGL should be kept in mind in the differential diagnosis of renal pelvic hemorrhage. In the patient who has an underlying history of coagulopathy nephrectomy can be avoided when there is awareness of AGL.
