An 83-years-old woman diagnosed with advanced Epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma was administered afatinib as a first-line treatment. On Day 17, the patient presented with grade 3 diarrhea and a blood test analysis showed an increased inflammatory response. Afatinib treatment was discontinued on the same day. ⋯ Drug-induced hypersensitivity syndrome (DIHS) was suspected, and the systemic administration of 30 mg/day prednisolone was administered. The symptoms subsided thereafter. A blood test analysis 3 weeks after onset revealed a reactivation of Human herpesvirus 6 (HHV-6) and a diagnosis of DIHS due to afatinib therapy was confirmed.

Hereditary spastic paraplegia (HSP) is a neurodegenerative disorder clinically characterized by slowly progressing spastic paraparesis. We herein report a 50-year-old Japanese woman who presented with slowly progressing spastic paraplegia and a history of Paget's disease of bone (PDB). ⋯ Arg155Cys; c.436C>T). This mutation has not been reported to cause HSP with PDB.

Ophthalmic carteolol is often used to treat glaucoma. Elderly patients with atrial fibrillation (AF) and chronic kidney disease (CKD) are common among the super-elderly in Japan. ⋯ We herein report an elderly patient with CKD who suffered bradycardia shock after the combined use of carteolol eye drops and verapamil for glaucoma and paroxysmal AF. This case highlights the fact that eye drops have a similar systemic effect to oral drugs, and especially in elderly patients with polypharmacy, drug interactions can unwittingly lead to serious events.

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 Linked-color imaging (LCI), a new technology for image-enhanced endoscopy, emphasizes the color of the mucosa, and its practicality in the detection of early gastric and colon cancers has been reported. However, whether or not LCI is useful for the diagnosis of Barrett's adenocarcinoma (BA) has been unclear. In this study, we explored whether or not LCI enhances the color difference between a BA lesion and the surrounding mucosa. ⋯ In LCI, the median color difference was 17.6, which was higher than that of WLI and BLI. Regardless of the morphology, color, and circumferential location of BA lesions, the color difference was larger in LCI than in WLI. Conclusion LCI increases the color difference between the BA and the surrounding Barrett's mucosa.
