Combination therapy with ipilimumab and nivolumab is indicated for many types of cancers; however, several patients experience immune-related adverse events (irAEs). We herein report a case of cytokine release syndrome (CRS) in a 63-year-old woman with stage IV left clear cell renal cell carcinoma. ⋯ Increased vascular permeability and relative adrenal insufficiency are considered to be the main pathogeneses. The early administration of high-dose steroids is crucial as a replacement for corticosteroids.

An 83-year-old man diagnosed with multiple myeloma presented with renal failure and hyperkalemia. The patient was treated with calcium polystyrene sulfonate (CPS: kalimate) for hyperkalemia. ⋯ There was a protrusion within the trachea surrounding the CPS crystals, inflammatory cells, and granulation tissue. This case suggests that CPS is associated with not only gastrointestinal complications, but also with airway complications.

Objective Although the body mass index (BMI) is considered a meaningful parameter for evaluating obesity, the association between the BMI and acute non-cardioembolic stroke remains unclear. We investigated how the BMI was related to patients' background, type of infarction, and infarction location in patients with non-cardioembolic stroke using an acute dual study (ADS) cohort. Methods The ADS trial was conducted between May 2011 and June 2017 in Japan. ⋯ In contrast, cortical infarct were frequent in the order of underweight, normal weight, overweight, and obese at 20%, 19%, 14%, and 3%, respectively (p=0.007). Conclusion Acute stroke patients with a high BMI have more atherosclerosis-related factors in their backgrounds than those with lower BMIs. In addition, the BMI may be a determinant of infarct location in patients with acute stroke.

Introduction Primary aldosteronism is characterized by the autonomous excretion of aldosterone, which may induce bone mineral disorders. Methods A total of 96 patients with primary aldosteronism were analyzed to identify differences in the regulation of serum calcium/phosphate balance between patients with unilateral and bilateral aldosterone hypersecretion and to determine whether or not adrenalectomy or mineralocorticoid receptor blockers affected such differences. Results Serum phosphate concentrations were significantly lower in patients with unilateral aldosterone hypersecretion than in patients with bilateral aldosterone hypersecretion (2.96±0.45 vs. 3.36±0.55 mg/dL, p<0.05), and recovered after adrenalectomy (2.96±0.45 vs. 3.49±0.32 mg/dL, p<0.01). ⋯ In responders, these levels tended to recover after treatment. A weak negative correlation between the plasma aldosterone concentration (PAC) and serum phosphate was observed, but there were no associations between the PAC and serum calcium concentration or between the aldosterone renin ratio and serum calcium and phosphate concentrations. Conclusion The effects on calcium/phosphate homeostasis may differ according to the primary aldosteronism subtype.

Objective This study clarified a variety of neurological phenotypes associated with varicella-zoster virus (VZV) reactivation. Methods This retrospective single-center study included consecutive patients with herpes zoster accompanied by neurological disturbances from April 2016 to September 2022. A comparative analysis was performed to examine whether or not the neurological phenotype and severity were associated with the distribution of herpes zoster, clinical and laboratory findings, and treatments. ⋯ Good recovery after admission was associated with a lower mRS value before the onset of neurological disability, clinical meningitis, and elevated cell counts and protein levels in the cerebrospinal fluid. Good recoveries were observed in patients with herpes zoster in the trigeminal or thoracic dermatomes more frequently than in other dermatomes. Conclusion This study revealed that VZV-related neurological complications are heterogeneous, commonly leading to severe disability and poor outcomes, and that neurological phenotypes and outcomes are related to the distribution of herpes zoster.
