Loxosceles spp are arthropods found worldwide. Its bite may produce cutaneous loxoscelism (necrotic or edematous) or cutaneous-visceral loxoscelism. Depending on their severity and location, cutaneous forms are managed with local cold application and systemic administration of antihistamines, corticosteroids, antibiotics, polymorphonuclear inhibitors, and analgesics. ⋯ PROSPERO ID CRD42023422424 (https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023422424).

Cutaneous vasculitis encompasses cutaneous components of systemic vasculitides, skin-limited variants of systemic vasculitides, such as IgA vasculitis or cutaneous polyarteritis nodosa, and single-organ cutaneous vasculitis, as individualized in 2012 in the Chapel Hill Consensus Conference Nomenclature. In this article, we focus on the management of skin-limited and single-organ vasculitides, often referred to, in clinical practice, as isolated "cutaneous leukocyctoclastic vasculitis", terms which may correspond to histological findings or descriptions, but are imprecise and not specific. Since most cases of isolated cutaneous vasculitis are self-limited and resolve spontaneously over 3 to 4 weeks, most patients require no systemic treatment. ⋯ Oral glucocorticoids may be required for a short period of time for painful, ulcerative, or otherwise severe disease in order to speed resolution. Among drugs which are reasonable longer-term options are colchicine, dapsone, azathioprine or hydroxychloroquine. Additional studies, including an ongoing multicenter randomized trial, are needed to determine the most effective therapies for skin-limited vasculitis.

To present a comprehensive review of dapsone-induced methemoglobinemia and its management. ⋯ Clinicians should recognize methemoglobinemia as an adverse effect associated with dapsone use and the potential factors that precipitate it. They should also know how to promptly and effectively manage this event.

Review Meta AnalysisChlorproguanil-dapsone for treating uncomplicated malaria.
In Africa, malaria is often resistant to chloroquine and sulfadoxine-pyrimethamine. Chlorproguanil-dapsone is a potential alternative. ⋯ There are insufficient data about the effects of the current standard chlorproguanil-dapsone regimen (three-dose, 2 mg chlorproguanil). Randomized controlled trials that follow up to day 28, record adverse events, and use an intention-to-treat analysis are required to inform any policy decisions.

Review[Guidelines for Prevention of Pneumocystis carinii Pneumonitis in Children and Adolescents with Cancer].
Pneumocystis carinii pneumonitis (PCP) is one of the most important opportunistic infections in children and adolescents with cancer. Its high frequency and a considerable mortality have led to primary chemoprophylaxis in patients with hematological malignancies and following allogeneic hematopoietic stem cell transplantation. Although less well characterized, patients with autologous stem cell transplantation and patients with dose-intensive chemotherapy for pediatric solid tumors may have a similarly high risk for PCP based on their profound T-cell depletion. ⋯ Secondary alternatives to TMP/SMX include oral dapsone, oral atovaquone, and aerosolized pentamidine-isethionate. These modalities are less effective than TMP/SMX, and have been evaluated predominantly in HIV-infected patients. This article reviews epidemiology and current approaches to chemoprophylaxis for PCP in children and adolescents with cancer and/or hematopoietic stem cell transplantation, and provides evidence-based guidelines for indications and modalities of PCP prophylaxis in this population.
