Extravascular cardiac resynchronization therapy (CRT) defibrillators (CRT-Ds) are ideal for recurrent blood stream infections. Furthermore, CRT is useful for patients intolerant to right ventricular (RV) pacing. The case was a 65-year-old man with a CRT-D who presented with a blood stream infection. ⋯ After the operation, a subcutaneous implantable cardioverter defibrillator (S-ICD) was placed. However, not all pacing is eligible for S-ICD screening. Combination therapy with an epicardial CRT device and S-ICD might be an alternate option for cardiac surgery cases.

We herein report a case of presumed septic shock due to Actinotignum schaalii bacteremia with urinary tract infection. A 65-year-old Japanese man suffering from a fever was diagnosed with septic shock due to urinary tract infection. A urine sample was additionally incubated under 5% CO2 and anaerobic conditions after A. schaalii was identified in a blood culture, but A. schaalii was not detected in the urine culture. If Gram-positive rods are observed on Gram staining of a urine sample in symptomatic patients with a predisposing urogenital condition, 5% CO2 and an anaerobic culture of a urine sample should be performed immediately.

Amyotrophic lateral sclerosis (ALS) due to a fused in sarcoma (FUS) P525L mutation is characterized by a rapidly progressive course. Multifocal motor neuropathy (MMN) may resemble ALS in early stage and is associated with anti-ganglioside antibodies. A 38-year-old woman was admitted to our hospital because of progressive muscle weakness in the right limbs. ⋯ Initially, we suspected MMN given the asymmetric muscle weakness and detection of anti-ganglioside antibodies. However, physical and electrophysiological tests did not support MMN, instead suggesting ALS. We confirmed a heterozygous P525L mutation and finally diagnosed this case as ALS due to an FUS mutation.

We herein report a case of nonbacterial thrombotic endocarditis (NBTE) in a patient with previously undiagnosed lung cancer. A 62-year-old woman presented to our hospital with multiple cerebral infarctions. There was no evidence of valvular heart disease or vegetations. ⋯ Unfortunately, she experienced further embolization and died. At a postmortem examination, she was diagnosed with NBTE and metastatic adenocarcinoma of the lung. Our experience with this patient suggests that DOACs may be an insufficient treatment for NBTE.
