In the context of the current coronavirus disease 2019 (COVID-19) pandemic, cutaneous lesions are being described. Here, we report on a 13-year-old girl with SARS-CoV-2-associated Henoch-Schönlein purpura and Epstein-Barr virus (EBV) infection. She presented without any respiratory symptoms, only a purpuric skin rash, abdominal pain, low-grade fever, and pharyngitis. Virology tests by polymerase chain reaction (PCR) were positive for SARS-CoV-2 and EBV. The potential association of Henoch-Schönlein purpura and SARS-CoV-2 should be kept in mind in order to reduce the spread of the virus, particularly in children with few respiratory symptoms.

We report a rare case of a 45-year-old Asian male patient with concurrent multiple myeloma (MM), immune thrombocytopenic purpura (ITP), and thalassemia trait, presenting with severe thrombocytopenia, back pain, and bleeding manifestations. The diagnosis was established through a combination of laboratory findings, imaging, and bone marrow biopsy, revealing 90% plasma cell involvement and KRAS/BRCA2 mutations. Management focused on controlling ITP with corticosteroids, rituximab, and platelet transfusions while addressing immunosuppression risks.

Immune thrombocytopenic purpura (ITP) is an autoimmune condition characterized by a reduced platelet count due to enhanced peripheral destruction and impaired platelet production. While thrombocytopenia is a well-documented complication of various viral infections, cytomegalovirus (CMV), a member of the Herpesviridae family, is primarily associated with infections in immunocompromised patients and is rarely implicated in causing severe thrombocytopenia in immunocompetent patients. This article aims to highlight the importance of considering CMV as a significant etiological factor in ITP, particularly in cases of asymptomatic thrombocytopenia.

Allosteric regulation of ADAMTS13 (A Disintegrin And Metalloproteinase with ThromboSpondin type-1 motif, member 13) activity involves an interaction between its Spacer (S) and CUB1-2 domains to keep the enzyme in a closed, latent conformation. Monoclonal antibodies (mAb) uncouple the S-CUB interaction to open the ADAMTS13 conformation and thereby disrupt the global enzyme latency. The molecular mechanism behind this mAb-induced allostery remains poorly understood.

Objectives: This study aimed to evaluate the safety profile of the recombinant zoster vaccine (RZV) after its marketing in China.
Methods: We present a descriptive analysis and safety signal assessment of adverse events following immunization (AEFI) associated with RZV between September 2020 and December 2023. The descriptive data collected includes demographic characteristics and the classification of characteristics of AEFI cases, while vaccine safety signal assessment was evaluated using the reporting odds ratio (ROR).

Pup odors and vocalizations integrate in the auditory cortex. A new study reveals that odor information is relayed to the auditory cortex by the basal amygdala and the activity of this projection enhances sound responses in females with pup experience.
