Purpose: This prospective study assessed the value of ultrasonography (US) in the evaluation of hepatosplenic fungal infections (HSFI).
Methods: Thirty-two pediatric participants with confirmed onco-hematological diseases and HSFI were included. Lesions in the liver and/or spleen were detected by US, magnetic resonance imaging (MRI), or computed tomography (CT).
Results: Of the participants, 11 (34%) had confirmed HSFI, while 21 (66%) had highly suspected HSFI. The US, CT, MRI, and fungal blood cultures demonstrated positive results in 31, 19, 25, and 7 patients, respectively. US had a significantly higher detection rate than CT, MRI, and fungal blood cultures (p < 0.05). The "bull's eye" phenomenon was a distinctive US feature of HSFI. Follow-up examinations indicated that after a mean of 7.7 (1-15) months, liver and/or spleen lesions disappeared in five patients. The lesion was significantly smaller in 10 patients. Residual calcifications were detected in 15 patients. Two patients died.
Conclusion: Conclusively, the US may substitute for tissue biopsy, other imaging modalities, or fungal blood culture for the confirmation of HSFI, and may guide better antifungal treatment, thus achieving better outcomes.

Concurrent Zoster Sine Herpete and Hepatosplenic Fungal Infection in a Cancer Patient: A Case Report.

In patients undergoing treatment for hematological cancers, like hairy cell leukemia (HCL), appropriate management of infections is of utmost importance. This paper describes the successful treatment of an HCL patient who had both visceral zoster sine herpete (ZSH) and hepatosplenic fungal infection, possibly caused by . To our knowledge, this is the first such case to appear in the literature, as these are rare conditions associated with states of immunosuppression, similar to those observed in hematological malignancy.

At present, there is still a lack of studies on HSC in patients with hematologic disorders. Based on The Chinese Guidelines for the Diagnosis and Treatment of Invasive Fungal Disease in Patients with Hematological Disorders and Cancers (the 6th revision), We retrospectively analyzed the clinical characteristics and prognosis of patients with HSC treated in Peking University Institute of Hematology from 2008 to 2022.

Article Synopsis
- Gram-negative coccobacilli are important pathogens that can lead to zoonotic infections in humans, especially causing infective endocarditis, which can be hard to diagnose.
- A 23-year-old male initially misdiagnosed with lymphoma was actually suffering from blood culture-negative endocarditis linked to these bacteria, showing symptoms like fevers, pancytopenia, and heart issues despite negative blood tests.
- The case emphasizes the need for careful consideration of these pathogens in patients with suspected endocarditis and highlights the importance of serological testing and a comprehensive treatment strategy for better patient outcomes.

Cat scratch disease (CSD) is an infection caused by Bartonella henselae, presents with non-specific symptoms like lymphadenopathy, fever, and fatigue. It can progress to disseminated disease, leading to complications such as liver and splenic micro abscesses, osteomyelitis, encephalitis, and uveitis. Diagnosis is challenging due to varied presentations and limited tests.

Background: The formation of gallstones is often accompanied by chronic inflammation, and the mechanisms underlying inflammation and stone formation are not fully understood. Our aim is to utilize single-cell transcriptomics, bulk transcriptomics, and microbiome data to explore key pathogenic bacteria that may contribute to chronic inflammation and gallstone formation, as well as their associated mechanisms.
Methods: scRNA-seq data from a gallstone mouse model were extracted from the Gene Expression Omnibus (GEO) database and analyzed using the FindCluster() package for cell clustering analysis.
