Nocardia exalbida, an uncommon Nocardia, was first identified in 2006. We herein report a 70-year-old man with pulmonary nocardiosis caused by N. exalbida after living-donor liver transplantation.

- Hypervirulent Klebsiella pneumoniae (hvKP) typically causes serious infections but rarely results in endocarditis, a type of heart infection.
- This report details a case where a patient developed infective endocarditis due to hvKP, which originated from liver and prostate abscesses, leading to complications like mitral regurgitation and requiring immediate surgery.
- The specific strain involved was identified as having a hypermucoid K1 capsular genotype and the rmpA gene, with its genome sequenced and shared in GenBank.
Preseptal cellulitis, an infection of the eyelid and skin around the eye, can be distinguished from orbital cellulitis. It is common in children and is rarely complicated. Streptococcus pyogenes is one of the major pathogens causing preseptal cellulitis.

Methods: We conducted a multicenter, randomized, single-blind, placebo-controlled, parallel assignment study in hospitalized patients with mild-to-moderate COVID-19 pneumonia. Patients were randomly assigned to receive favipiravir alone (n = 24) or nafamostat with favipiravir (n = 21).
Article Synopsis
- Several cases of COVID-19-associated leukoencephalopathy have been reported, often linked to hypoxia, but the exact mechanisms and outcomes are still not fully understood.
- A case study of a 65-year-old woman illustrates that leukoencephalopathy can occur without severe hypoxia, as she experienced altered consciousness and abnormal behavior after developing COVID-19 pneumonia following treatment for pyelonephritis.
- The study emphasizes the need for clinicians to consider leukoencephalopathy when diagnosing consciousness issues in COVID-19 patients, even in the absence of significant hypoxia, and notes that gradual neurological recovery is possible.
Article Synopsis
- - The study examined the clinical outcomes of critically ill COVID-19 patients in Tokyo, noting that prior literature on this topic is scarce.
- - Fourteen patients on mechanical ventilation were analyzed; most were male with pre-existing health issues like hypertension and diabetes, showing a 28-day mortality rate of 35.7% due to respiratory failure.
- - The findings indicate a high mortality rate in intensive care settings for COVID-19 and suggest the need for further research on optimal treatment strategies and timing for mechanical ventilation.
