Many cases of primary aldosteronism (PA) in patients who developed hypokalemia-induced rhabdomyolysis and underwent adrenalectomy for aldosterone-producing adenoma (APA) have been reported; however, the immunohistopathological and molecular features remain unknown. We herein report the case of a 28-year-old woman with PA who presented with hypokalemia-induced rhabdomyolysis and underwent adrenalectomy for unilateral APA. ⋯ A genetic analysis revealed a somatic mutation in the KCNJ5. These findings suggest a strong aldosterone production capacity in our patient's adenoma, which was presumably related to her severe hyperaldosteronism and the resultant hypokalemia-induced rhabdomyolysis.

Hangeshashinto is a traditional Japanese herbal medicine that is widely recognized for its efficacy in relieving mucositis induced by chemotherapy and radiotherapy. We herein present the cases of two patients with head and neck cancer who were clinically diagnosed with severe drug-induced interstitial lung disease (DILD) following Hangeshashinto administration for radiation-induced mucositis. Although Hangeshashinto has beneficial properties, it is also associated with a relatively low incidence of DILD, including some reports of death. To ensure patient safety, greater attention should be paid when prescribing Hangeshashinto, especially for elderly patients with factors predisposing them to develop severe DILD.

Objective The ratio of hemoglobin to red blood cell distribution width (Hb/RDW) is a simple and readily available tool associated with adverse outcomes in chronic heart failure (HF). However, the association between the Hb/RDW ratio and mortality in patients with acute decompensated HF (ADHF) is unclear. The goal of this study was to investigate the relationship between the Hb/RDW ratio and mortality in patients after ADHF. ⋯ A Kaplan-Meier analysis revealed that patients in the lower Hb/RDW ratio group (<0.24, n=131) had worse outcomes compared to those in the higher group (≥0.24, n=119) (cumulative incidence 44.1% vs. 19.5%, respectively; log-rank, P <0.001). After adjusting for demographics, HF severity, and laboratory biomarkers, a lower Hb/RDW ratio was significantly associated with a higher risk of mortality (hazard ratio, 1.89; 95% confidence interval, 1.04-3.45; P = 0.038). Conclusion A lower Hb/RDW ratio is associated with an increased risk of mortality in patients after ADHF, thus indicating its potential utility in identifying patients at an elevated risk for future cardiovascular events.

Progressive supranuclear palsy (PSP) is characterized by progressive postural instability, falls, and supranuclear vertical gaze abnormalities. In this report, we present the case of a 71-year-old woman with dopa-responsive rest tremor followed by tachyphemia and postural instability. ⋯ Based on the diagnostic criteria for PSP, the patient was diagnosed with probable PSP-RS. The clinical manifestations observed in our patient are unique and are considered important for illustrating a broad spectrum of PSP syndrome.
