Ceftriaxone-associated Biliary Pseudolithiasis with Elderly Type 1 Diabetes Mellitus: Two Case Reports.
Biliary pseudolithiasis is a ceftriaxone (CTRX)-induced complication, but the risk in cases of elderly type 1 diabetes mellitus (T1DM) is unclear. Case 1: A 78-year-old woman with T1DM complicated by diabetic autonomic neuropathy was admitted with pneumonia and treated with CTRX. On day 8, biliary pseudolithiasis and cholecystitis were observed. ⋯ After a week, she developed asymptomatic biliary pseudolithiasis with gastroparesis. CTRX-associated biliary pseudolithiasis was thus noted in these cases of elderly T1DM. CTRX should be cautiously administered, especially in elderly T1DM patients with diabetic autonomic neuropathy.

We herein report a case of congenital bilateral hypoplasia of the internal carotid artery (ICA) that was diagnosed by bone window computed tomography (CT) and cerebral angiography. A 23-year-old woman presented with left dominant quadriplegia. Brain magnetic resonance imaging showed not only massive infarcts in the anterior circulation but also poor depiction of the bilateral ICAs. ⋯ Cerebral angiography revealed narrowing of each ICA above its bifurcation, and the blood supply to the intercranial carotid systems developed from the vertebrobasilar system through the posterior communicating arteries and posterior cerebral arteries. We diagnosed the patient with congenital bilateral hypoplasia of the ICA based on bone CT and cerebral angiography findings. Performing both bone window CT and cerebral angiography can facilitate the diagnosis of congenital hypoplasia of the ICA.

Lessons Learnt from Case Series of Out-of-hospital Cardiac Arrest and Unexpected Death after COVID-19 Vaccination.
Vaccination against COVID-19 has raised concerns about myocarditis in young men, as out-of-hospital cardiac arrest (OHCA) or sudden death after vaccination has been reported sporadically. Common features of these cases are occurrence in young men, within a few weeks after vaccination, in patients with no structural heart diseases. ⋯ Both myocarditis and J waves are prevalent in young men, and these cases imply that myocarditis augments J waves, which trigger VFs, and primary electrical disorders are a leading cause of death. To prevent such issues, artificial intelligence (AI)-assisted interpretation of historical electrocardiogram findings may help predict future J wave formation leading to VF, as digital electrocardiogram (ECG) findings are well suited for AI interpretation.

Objective The interleukin-6 (IL-6) inhibitor satralizumab is an established treatment for neuromyelitis optica spectrum disorder (NMOSD). Although IL-6 inhibitors are generally well-tolerated, serious infections, including sepsis, can occur. In this study, we compared the sepsis characteristics in NMOSD patients administered satralizumab (NMOSD-satralizumab) to those in rheumatoid arthritis patients administered tocilizumab (RA-tocilizumab), another IL-6 inhibitor. ⋯ Urosepsis was relatively infrequent in RA-tocilizumab (term 1: 24.2%, term 2: 20.1%). Conclusion Safe satralizumab use requires risk factor assessment to minimize the incidence of severe infections. Management of UTIs is also recommended.
