Case Reports
An Autopsy Case of Late-onset Fulminant Myocarditis Induced by Nivolumab in Gastric Cancer.
Nivolumab is an immune-checkpoint inhibitor (ICI) that can induce unique treatment-related toxicities, such as immune-related adverse events (irAEs). Myocarditis is a serious irAE with an incidence between 0.06% and 1.14%. ⋯ Pathological complete remission of the primary lesion was confirmed by the autopsy. We should consider possible complications of cardiac irAEs, especially fulminant myocarditis, even beyond three months after starting ICI therapy.

Objective Whether or not combined lifestyle factors are associated with similar decreases in risks of incident hypertension and diabetes among individuals with and without chronic kidney disease (CKD) remains unclear. Methods This population-based prospective cohort study included participants 40-74 years old who were free from heart disease, stroke, renal failure, hypertension, diabetes, and hypercholesterolemia at baseline (n =60,234). Healthy lifestyle scores (HLSs) were calculated by adding the total number of 5 healthy lifestyle factors (non-smoking, body mass index <25 kg/m2, regular exercise, healthy eating habits, and moderate or less alcohol consumption). ⋯ Compared with adhering to 0, 1, or 2 components, adherence to all 5 HLS components was associated with a nearly one-half reduction in the risk of hypertension [hazard ratio (HR) =0.52; 95% confidence interval (CI), 0.45-0.60] and diabetes (HR=0.51; 95% CI, 0.32-0.81) in fully adjusted models. CKD did not have a modifying effect on associations between the HLS and incident hypertension (Pinteraction=0.6) or diabetes (Pinteraction=0.3). Conclusion Adherence to HLS components was associated with reduced risks of incident hypertension and diabetes, regardless of CKD status.

Case Reports
A Case of Cardiac Dysfunction Due to Thiamine Deficiency after Hemodialysis for Biguanide-related Lactic Acidosis.
Biguanide is an ideal drug for the treatment of type 2 diabetes mellitus. When used appropriately, the incidence of lactic acidosis is reported to be very low. ⋯ We herein report a case of cardiac dysfunction due to thiamine deficiency after hemodialysis in a patient with suspected biguanide-related lactic acidosis. Patients who develop severe lactic acidosis while taking biguanides should be given a large dose of thiamine without delay, given the possibility of thiamine deficiency as a complication.

Both 1,3-beta-D-glucan (BDG) and galactomannan (GM) are polysaccharide components of the fungal cell wall. Although elevated levels of serum BDG and Aspergillus GM suggest invasive fungal infection or Pneumocystis pneumonia and aspergillosis, respectively, it is also necessary to consider the possibility of false-positives. ⋯ The false-positive serum BDG and GM findings may have been due to his aspiration of food containing them. It is important to take a detailed history of aspiration in addition to making a conventional differential diagnosis in patients with pneumonia with elevated serum BDG and GM levels.

A 38-year-old man with renal cell carcinoma was referred to our hospital because of a productive cough. He had received radiotherapy for lung metastasis and been treated with axitinib. ⋯ Although radiotherapy in combination with axitinib carries a risk of causing airway toxicity, MRSA necrotizing bronchitis has not been reported. Physicians should consider the possibility of infectious necrotizing bronchitis if irradiated patients show prolonged respiratory symptoms.
