Monkeypox 2024 outbreak: Fifty essential questions and answers.

As the world still vividly recalls the previous monkeypox (mpox) outbreak that impacted over 120 countries worldwide with more than 99,000 cases in 2022, we are now facing a second wave of infections from the monkeypox virus (MPXV), characterized by an exponential increase in cases. The current 2024 outbreak has already recorded more than 20,000 cases in Africa, marking a dramatic escalation compared to previous outbreaks. The predominance of the newly identified clade Ib variant, first detected in the Democratic Republic of the Congo (DRC) and now identified across multiple African nations and beyond, underscores its enhanced transmissibility and potential for international spread, evidenced by cases in Sweden and Thailand.

Cold Atmospheric Plasma Induces Growth Arrest and Apoptosis in Neurofibromatosis Type 1-Associated Peripheral Nerve Sheath Tumor Cells.

Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder resulting from mutations in the gene. Patients harboring these mutations are predisposed to a spectrum of peripheral nerve sheath tumors (PNSTs) originating from Schwann cells, of which malignant peripheral nerve sheath tumors (MPNSTs) are the deadliest, with limited treatment options. Therefore, an unmet need still exists for more effective therapies directed at these aggressive malignancies.

Tryptase in drug-induced anaphylaxis: the need for acute and baseline values.

Purpose Of Review: The purpose of this narrative review was to summarize data and official recommendations purporting to paired tryptase determination in patients experiencing drug-induced anaphylaxis, published between January 1, 2023 and June 1, 2024.

Recent Findings: Three main lines of evidence obtained through paired acute and baseline tryptase determination were identified: diagnostic criterion for hypersensitivity reactions involving systemic mast cell activation; differential diagnostic criterion for hypersensitivity reactions involving other mechanisms of immediate reactions; and added value of acute and baseline tryptase levels for personalized management following drug-induced anaphylaxis: cause, risk of recurrence, underlying mast cell conditions including hereditary α-tryptasemia, familial clusters.

Summary: The implementation of existing guidelines which consensually recommend paired tryptase measurement is a persistent unmet need hampering optimal diagnosis of drug-induced anaphylaxis and patient management.
