Myoglobin is a well-known cause of acute kidney injury (AKI) due to rhabdomyolysis. However, whether or not removing serum myoglobin by on-line hemodiafiltration (OHDF) improves the kidney function remains unclear. ⋯ A urinalysis and blood collection results obtained before and after OHDF demonstrated that OHDF improved the kidney function by removing a large amount of serum myoglobin rather than via urinary excretion. In conclusion, OHDF may prevent AKI progression effectively when the urine volume is insufficient.

A 76-year-old man undergoing hemodialysis complained of pain and discoloration of his right finger. The hemodialysis arteriovenous fistula was in the right upper extremity. Ultrasonography showed right subclavian artery occlusion. ⋯ Thus, we performed the procedure after exposing the proximal brachial artery. We were able to recanalize the subclavian artery and restore blood flow to the right upper extremity. When the lesion is on the side of the arteriovenous fistula and approaching from the lower extremity is difficult, exposure of the proximal brachial artery can be considered.

Review Case Reports
Adult-onset Still's disease with Acute Kidney Injury Requiring Hemodialysis: A Case Report and Literature Review.
Adult-onset Still's disease (AOSD) is characterized by high spiking fever, evanescent rash, and arthritis. However, AOSD rarely presents with severe acute kidney injury (AKI). We herein present the case of a 56-year-old woman with new-onset AOSD who rapidly developed AKI. ⋯ The patient was diagnosed with AOSD complicated by AKI and macrophage activation syndrome. Treatment with high-dose steroids, hemodialysis, and plasma exchange successfully resolved her AKI. In this report, we review previously published reports on AOSD accompanied by AKI and discuss this rare complication in AOSD.

Review Case Reports
The Onset of Food-dependent Exercise-induced Anaphylaxis in an Elderly Patient: A Case Report.
The development of allergic diseases is common in the young but rare in the elderly. We encountered an elderly patient with food-dependent exercise-induced anaphylaxis (FDEIA). ⋯ Based on our review of the existing literature, this was the oldest patient to ever be diagnosed with FDEIA in Japan. This case suggests that physicians should keep in mind that older adults can develop FDEIA.

Review Case Reports
Indications for Percutaneous Drainage in Patients with Huang Class 3B Emphysematous Pyelonephritis: A Case Report and Literature Review.
Emphysematous pyelonephritis (EPN) is a severe urinary tract infection common in patients with diabetes. Nephrectomy is recommended when the Huang classification is ≥3B. We herein report a case in which nephrectomy was avoided using antimicrobial agents and percutaneous drainage (PCD). ⋯ The causative bacteria were Escherichia coli. Despite high-risk factors, EPN was cured with kidney preservation and PCD because the emphysema and abscess were not extensive. Thus, PCD should be considered in patients with Huang Class 3B EPN and high-risk factors if emphysema and abscess are not extensive.
