Objective Peripheral blood-derived inflammation-based scores, such as the neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and the combination of platelet count and NLR, have recently been proposed as prognostic markers in solid tumors. The purpose of this study was to investigate the validity of inflammatory markers as predictive prognostic factors for locally advanced oral squamous cell carcinoma (OSCC). In addition, we evaluated the potential correlation between systemic inflammation and local expression of COX2. Study Design Retrospective chart review and histologic analysis. Setting Tertiary referral academic center. Subjects and Methods We conducted a retrospective analysis of 94 patients with advanced OSCC treated with surgery at our hospital between 2007 and 2015. The relationship among patient survival, systemic inflammatory markers, and local COX2 expression was evaluated. Local COX2 expression in surgical specimens was measured by immunohistochemistry. Results High NLR and high PLR were associated with significantly shorter overall survival and cancer-specific survival. Multivariate analysis revealed that cN stage, NLR, and postoperative radiation/chemoradiation were significantly associated with overall survival and cancer-specific survival. PLR and combination of platelet count and NLR were significantly correlated with tumor expression of COX2. Finally, patients with cN2 stage disease and high local COX2 expression had a significantly worse prognosis than other patient groups. Conclusion Pretreatment inflammatory markers are useful as prognostic factors in advanced OSCC. Our study suggests that local COX2 may be affected by systemic inflammation and that the prognostic impact of COX2 expression depends on host factors and tumor characteristics.

PD-L1 expression was associated with CD8 tumor-infiltrating lymphocytes and better outcome in patients with LAOSCC.

This study included 30 patients (17 males and 13 females; mean age, 73.7 ± 13.1 years) who were diagnosed with dehydration based on vital signs, skin symptoms, and blood test findings by emergency medicine physicians. First, the attending physician of our department measured oral mucosal dryness. Subsequently, the emergency medicine physician blindly divided the severity of dehydration into three stages according to clinical findings and blood test results. In this study, the oral moisture‐checking device (Mucus®; Life Co., Ltd., Saitama, Japan) was used to measure the oral mucosal dryness. We examined the oral moisture level for each dehydration severity level and the correlations of each severity level of dehydration with the measured values. Spearman's correlation coefficient (Medcalc version 11.3 for Windows) was used for statistical analysis. P < 0.05 indicated significant differences. Twenty‐six patients were diagnosed with dry mouth, and a moderate negative correlation was found between the severity of dehydration and oral moisture degree ( r = −0.686). The correlation coefficient for the relationship between oral moisture degree and severity of dehydration was −0.686, indicating a negative correlation ( P < .05). These results suggest that the oral mucosal dryness may be a useful index of dehydration severity.

We report a case of a 44-year-old woman with nephrotic syndrome who underwent renal biopsy three times. On each occasion, light microscopy showed membranous nephropathy with mild to moderate thickening of the glomerular capillary walls. Immunofluorescence microscopy showed predominant deposition of immunoglobulin (Ig) G, IgG1, IgG2, IgG3, and IgG4; C3; and C1q along the glomerular capillary walls and deposition of IgM and IgA in some parts of the walls. Electron microscopy revealed the accumulation of electron-dense deposits in the mesangium and the subepithelial area of the glomerular basement membrane. Virus-like particles were detected in the subendothelial cells in all three biopsy specimens. A definitive diagnosis of systemic lupus erythematosus (SLE) was made at the time of the second admission, when she was 31 years old. A diagnosis of membranous lupus nephritis was then made on the basis of the pathological and clinical findings. A change in anti-single-stranded (ss)DNA antibody titers was of particular interest in this patient. Occasional small increases in anti-double-stranded (ds)DNA antibody were found, but increased anti-ssDNA antibody titers occurred before there was any elevation of urinary protein during renal relapse, and a sustained increase in the titers was shown subsequently. Hypocomplementemia occurred in parallel with the increase of anti-ssDNA antibody. Immunosuppressive therapy with steroid promptly eliminated anti-dsDNA antibody, but anti-ssDNA antibody remained positive. The patient had normocomplementemia and proteinuria was absent. Later, anti-ssDNA antibody decreased. Renal function has remained in the normal range for 20 years.
