We herein report a 40-year-old Japanese man with chronic hepatitis B genotype C (viral load 6.7 LC/mL) who developed hepatocellular carcinoma (HCC) despite achieving undetectable hepatitis B virus (HBV) DNA levels with nucleos (t) ide analog (NA) treatment (entecavir). Notably, his hepatitis B surface antigen (HBsAg) level remained elevated at 388.4 IU/mL. Given the continued risk of carcinogenesis associated with HBsAg positivity, we initiated pegylated interferon (PEG-IFN) therapy one month after HCC surgery. Following three periods of PEG-IFN treatment, HBsAg seroclearance (HBsAg-negative state) was achieved.

Objectives To assess the association between concomitant use of central nervous system drugs and femoral fracture risk in individuals ≥80 years old in Japan. Methods A case-crossover design was used, defining the case period as 3 days before the fracture diagnosis and the control period as 31-33, 34-36, and 37-39 days prior. ⋯ Results In 255,875 patients, the concomitant use of central nervous system drugs increased the odds ratios of femoral fracture (3.41[95% confidence interval: 3.27-3.55], 3.69 [3.46-3.91], 3.76 [3.42-4.13], and 4.34 [3.86-4.86] for an intake of >0-1, >1-2, >2-3, and >3 central nervous system drugs, respectively). Conclusions The concomitant use of central nervous system drugs is associated with an increased risk of femoral fractures in individuals ≥80 years old in Japan.

We herein report an 80-year-old man showing a downsloping TP segment together with an increase in the height of the T wave in the precordial leads on a standard 12-lead electrocardiogram (ECG). Separately, an 87-year-old woman showed only a downsloping TP segment in the precordial leads on a standard 12-lead ECG. ⋯ This downsloping TP segment in the precordial leads on the standard 12-lead ECG is thought to be due to a cardiac impulse-tapping artifact. Differential diagnoses are also discussed.

A 55-year-old woman presented to her primary care physician with facial and lower leg edema. After being referred to our hospital because of hypothyroidism and hypokalemia on blood tests, she also had elevated adrenocorticotropic hormone (ACTH) and cortisol levels, but a dexamethasone suppression test showed no cortisol suppression. Ectopic ACTH syndrome due to pancreatic neuroendocrine carcinoma (PNEC) was suspected. endoscopic ultrasound-guided fine-needle aspiration was performed, and a histopathological examination of the obtained specimen revealed multiple liver metastases of the PNEC. Imaging after etoposide and cisplatin therapy showed cystic changes in the primary lesions and shrinkage of the liver metastases, and the ACTH levels were within the normal range.
