A 24-year-old man was admitted to our hospital because of severe heart failure. Although he was treated with diuretics and positive inotropic agents, his heart failure progressed. ⋯ After starting administration of an iron-chelating agent in addition to conventional treatment for heart failure, his condition improved. We should consider hemochromatosis in heart failure patients with severe right ventricular dysfunction in addition to left ventricular dysfunction.

The patient was 57 years old when he was diagnosed with amyotrophic lateral sclerosis (ALS) at 1 year after developing bulbar symptoms. At 58 years old, he stated that he was considering donating his kidney to his son suffering from diabetic nephropathy. ⋯ Nephrectomy was performed 30 min after his cardiac death. Organ donation spontaneously proposed by an ALS patient should be considered in order to meet the requests of patients who want their families and other patients to live longer, thereby imparting a beneficial legacy through their deaths.

Objective Dupilumab, a monoclonal antibody specific for the human interleukin (IL)-4 receptor α, is used to treat severe asthma, especially in patients with elevated blood eosinophil counts and fractional exhaled nitric oxide (FeNO). The therapeutic response to dupilumab is highly variable. In this study, we explored new serum biomarkers to accurately predict the effect of dupilumab and examine the effect of dupilumab based on changes in the clinical parameters and cytokine levels. ⋯ Serum type 2 cytokines were equivalent between responders and non-responders; the baseline serum IL-18 level was significantly lower in responders than in non-responders (responders, 194.9±51.0 pg/mL; non-responders, 323.4±122.7 pg/mL, p=0.013). The cut-off value of IL-18 at 230.5 pg/mL could be used to distinguish non-responders from responders (sensitivity 71.4, specificity 80.0, p=0.032). Conclusion A low baseline serum IL-18 level may be a useful predictor of an unfavorable response to dupilumab in terms of the ACQ-6.

A 56-year-old man presented with a history of hypertension; clinically, the patient had primary aldosteronism (PA) and a 4-cm left adrenal tumor. The left adrenal glands, resected by adrenalectomy, also contained ectopic thyroid tissue (ETT). ⋯ This is the first case of adrenal ETT coexisting with APA, confirmed by steroid-converting enzyme expression. Further analyses using cumulative case data are required to clarify the correlation between adrenal ETT and APA.

Review Case Reports
Hidden Bow Hunter's Syndrome Diagnosed Using Dynamic Cerebral Angiography and Successfully Treated with Spinal Surgery: A Case Report and Review of the Literature.
Hidden bow hunter's syndrome (HBHS) is a rare disease in which the vertebral artery (VA) occludes in a neutral position but recanalizes in a particular neck position. We herein report an HBHS case and assess its characteristics through a literature review. A 69-year-old man had repeated posterior-circulation infarcts with right VA occlusion. ⋯ Decompression of the VA successfully prevented stroke recurrence. HBHS should be considered in patients with posterior circulation infarction with an occluded VA at its lower vertebral level. Diagnosing this syndrome correctly is important for preventing stroke recurrence.
