Objective This study examined whether or not the disease control in Japanese patients with systemic lupus erythematosus (SLE) had improved in recent years and its possible association with altered balance between the use of glucocorticoids and immunosuppressants. Methods We enrolled Japanese patients with SLE who visited our medical center during 2013-2017 (Group A, 75 patients) and compared them with patients encountered during 1999-2003 (Group B, 69 patients; not overlapping with Group A). Patient background characteristics, doses of glucocorticoids, and the use of immunosuppressants at the times of SLE onset and disease flares were reviewed from the medical records. ⋯ The median number of SLE flares per person-year was significantly lower in Group A than in Group B (0 vs. 0.3, respectively, p<0.001), and a propensity score-matched analysis indicated the association of SLE flare with the non-use of immunosuppressants in the initial treatment (p=0.012). The rates of infectious diseases and other complications were similar between the groups. Conclusion The recent aggressive use of immunosuppressants in Japan resulted in a reduction in the rate of SLE flare.

We performed endocytoscopy (ECS) for the ex vivo evaluation of mesothelioma in specimens biopsied during medical thoracoscopy in three patients. We evaluated 19 biopsy specimens based on the density of nuclei and irregularity in the nuclei shape using ECS and compared them with the histopathological findings. ⋯ The nine specimens evaluated as non-malignant based on ECS consisted of six specimens diagnosed as malignant based on histopathology and three diagnosed as non-malignant based on histopathology. ECS was feasible and had some utility for ex vivo ultra-magnifying imaging of thoracoscopic biopsy specimens from patients with mesothelioma.

Objective Left ventricular (LV) thrombus is a rare condition in acute cerebral infarction. The prevalence and features of cerebral infarction with LV thrombus are unclear. We explored the features of cerebral infarction due to LV thrombus. ⋯ Six (46%) patients were found to have good outcomes (modified Rankin Scale 0-2) at 90 days after the onset. Conclusion LV thrombus was seen in 0.9% of patients with CES. Many of the patients with LV thrombus had major vessel occlusion.

Objective Helicobacter pylori antibody kits using the latex immunoassay (LIA) are widely used in Japan. However, the optimal cut-off of the LIA remains unclear. This study clarified the optimal cut-off of the LIA for assessing the current infection status of patients (currently infected, never infected, spontaneously eradicated) in clinical practice. ⋯ When applying the cut-off of 4 U/mL to the judgment of current infection in all subjects, the sensitivity and specificity were 92.1% and 92.6%, respectively. Conclusion Our findings suggest that 4 U/mL was the optimal cut-off for differentiating current infection from no prior infection, and the value may be stable because of the exclusion of subjects with spontaneous eradication. The cut-off may be useful in initial screening for current H. pylori infection.

Objective This study aimed to reveal the screening performance of a color-changeable chewing gum test for a decreased masticatory function in the assessment of oral hypofunction in patients with metabolic diseases. Methods We analyzed 1,000 patients with metabolic diseases, including diabetes, dyslipidemia, hypertension, and hyperuricemia. A decreased masticatory function was diagnosed by a gummy jelly test. ⋯ The optimal cut-off point of the color scale was 5.5 (5.0-6.5) points, whereas that of delta E was 37.7 (35.5-38.8) units. The optimal cut-off points were not significantly different between the subgroups divided by clinical characteristics. Conclusions A color-changeable chewing gum test using the color scale as well as delta E would be a useful tool for screening patients with metabolic diseases for a decreased masticatory function in the assessment of oral hypofunction.
