Objective Ceftriaxone (CTRX) is a widely used antibiotic because of its long plasma half-life and good tissue transmission. Many of the reported studies on CTRX-associated pseudolithiasis were performed in children. Although some studies have been published in adults, there are no studies limited to elderly people. ⋯ A propensity analysis determined that the frequency of pseudolithiasis was increased in patients treated with >19 g total CTRX compared with those who received ≤19 g in total (OR 4.06, 95% CI 1.45-11.32, p=0.008). Conclusion The incidence rate of CTRX-induced pseudolithiasis is high in elderly people, and the CTRX dose and CTRX treatment duration are significant risk factors for pseudolithiasis. A total dose of >19 g increases the likelihood of pseudolithiasis formation in elderly people treated with CTRX.

Hypoglycemia should be avoided when treating patients with diabetes. Repaglinide is an insulin secretagogue with a low hypoglycemic risk because of its rapid- and short-acting effects. ⋯ We herein report an elderly patient with type 2 diabetes mellitus and severe renal insufficiency who received repaglinide and hypoglycemia three days after starting clopidogrel. The concomitant use of repaglinide and clopidogrel can lead to hypoglycemia, especially in patients with severe renal insufficiency.

Objective This study evaluated cases of pruritus, which is known to be associated with sleep disorder, in chronic liver disease (CLD) patients. Methods Questionnaires were given to 339 enrolled CLD outpatients in winter (November 2019 to March 2020) and again in summer (April to October 2020) (median interval: 104 days). Relative changes in symptoms shown by a visual analogue scale (VAS) and Kawashima's pruritus score between winter and summer were evaluated in Study 1 (n=199), while Study 2 examined the clinical features of patients with sleep disorder based on the results of the second questionnaire (n=235, median age 70 years old; 141 men, liver cirrhosis 37%). ⋯ The cut-off for the daytime and nighttime VAS values for existing sleep disorder were 1.6 [area under the curve (AUC) 0.901] and 3.4 (AUC 0.931). The respective sensitivity, specificity, and positive and negative predictive values for sleep disorder based on Kawashima's score (≥2) were 0.85, 0.28, 0.10, and 0.95 for the daytime and 1.00, 0.29, 0.12, and 1.00 for the nighttime. Conclusion Intervention against pruritus is recommended in CLD patients with a high Kawashima's score (≥2) in any season, especially with an elevated FIB-4 index.

Objective It has been reported that anti-mitochondrial antibodies (AMAs) recognize mitochondrial antigens and are associated with some diseases involving multiple organs, such as primary biliary cholangitis, Sjögren syndrome, Hashimoto's thyroiditis, systemic sclerosis, interstitial pneumoniae, dilated cardiomyopathy, and tubulointerstitial nephritis. In the current study, we examined the prevalence of AMAs in patients with dilated cardiomyopathy (DCM) and their clinical characteristics. Methods We enrolled 270 patients with DCM. ⋯ During the follow-up period, two of the three patients died due to respiratory failure. The other patient survived but experienced type II respiratory failure. Conclusion The prevalence of AMAs in 270 DCM patients was only 1.1%, and these patients suffered from respiratory failure.

Objective Maoto is a traditional Japanese Kampo formula used to treat influenza. However, clinical evidence for maoto has been limited to small-scale studies of its effect in alleviating symptoms. The present study evaluated whether or not the addition of maoto to a neuraminidase inhibitor was associated with a reduction in hospitalization following influenza. ⋯ The difference between these treatment groups was nonsignificant (common odds ratio, 0.95; 95% confidence interval, 0.74 to 1.22; p=0.695). Conclusion The addition of maoto to a neuraminidase inhibitor was not associated with a decrease in hospitalization among nonelderly patients with influenza. Further research is necessary to clarify the indication and efficacy of maoto.
