Case Reports
Atypical Cogan's Syndrome with Large-vessel Vasculitis Successfully Treated with Tocilizumab.
A 61-year-old man presented with weight loss, bilateral ocular redness, blurred vision, and sensorineural hearing loss. Fluorodeoxyglucose-position emission tomography/computed tomography demonstrated an uptake in the ascending and descending aorta, abdominal aorta and femoral arteries. ⋯ He was treated with high-dose prednisolone and subcutaneous tocilizumab (162 mg/week), resulting in successful improvements in his ocular and vascular involvements. Although there is currently no established treatment strategy for LVV associated with Cogan's syndrome, our case and literature review suggest that tocilizumab is a viable treatment option for this rare but life-threatening complication.

Objective Pleural effusion (PE) is a common adverse event that occurs during dasatinib therapy for chronic myeloid leukemia (CML). However, the pathomechanism of PE and appropriate management of Asian patients with CML have not been elucidated. This study investigated the incidence rate, risk, and appropriate management of PE in Asian patients with CML treated with dasatinib. ⋯ A multivariate analysis revealed that age ≥65 years old was the only independent risk factor for PE. Dasatinib dose reduction and switching to a tyrosine kinase inhibitor showed a statistically significant difference in effectively reducing PE volume compared to single diuretic use. Conclusion Although further studies are warranted, our observations showed that advanced age is a significant risk factor for PE, and tyrosine kinase inhibitor dose reduction or replacement of dasatinib may be an effective management strategy for PE in Asian CML patients who received first-line treatment with dasatinib in real-world clinical practice.

Thyroid storm is a life-threatening clinical condition that is usually triggered by untreated or interrupted treatment of Graves' disease, leading to the sudden onset of severe thyrotoxicosis, which requires an immediate diagnosis and treatment based on diagnostic criteria. Cases of thyroid storm caused by painless/painless subacute thyroiditis are very rare. We herein report an 85-year-old man with features of severe thyrotoxicosis caused by painless/painless subacute thyroiditis who had no uptake of 99mTcO4 and was negative for thyroid-stimulating hormone receptor antibodies. In thyroid storm patients in whom the findings are inconsistent with Graves' disease, careful follow-up and management are necessary, assuming the possibility of painless or painless subacute thyroiditis.

Atezolizumab and bevacizumab are currently available as first-line treatments for unresectable hepatocellular carcinoma, but immune-related adverse events are a major concern. We herein report two cases of isolated adrenocorticotropic hormone (ACTH) deficiency. ⋯ Endocrinological investigations revealed unsatisfactory ACTH and cortisol responses despite the preservation of other anterior pituitary hormones, suggesting isolated ACTH deficiency. As it is rapidly improved by steroid replacement therapy, an early diagnosis and treatment make it possible to resume immunotherapy.

We herein report two cases of atrial pacing with coronary sinus (CS) pacing performed to improve hemodynamic instability in cardiogenic shock due to percutaneous coronary intervention (PCI)-induced sick sinus syndrome (SSS). Ventricular pacing alone made it difficult to stabilize hemodynamics due to SSS, which had been caused by the lack of reflow and slow flow of the sinus node artery (SNA) jailed with a stent. Adding atrial pacing with CS pacing may be useful, as in our two cases, where ventricular pacing alone was unable to stabilize hemodynamics.
