A Virtual Assessment Model for At-Home Evaluation of Suspected Viral Hemorrhagic Fever Cases.

The Sudan virus disease outbreak in 2022 prompted the Denver Health High-Risk Infection Team (HITeam) to evaluate and implement novel strategies to respond to viral hemorrhagic fever (VHF) events. To improve the VHF response, HITeam members developed a virtual assessment model (VAM) for at-home evaluation of individuals who are suspected of having a VHF. The VAM incorporates aspects of care that would normally be rendered in a high-level isolation unit-including assessment and monitoring, specimen collection, provider consultation, patient and family teaching, and pharmaceutical intervention-into a mobile framework in which team members respond to a suspected case at the individual's home.

[Rose necrosis: Necrotizing granulomatous reaction with infected node at red pigment of a tattoo].

Introduction: Nowadays, necrotizing cutaneous reaction after a tattoo is rare especially with the sterile tattoo equipment and antisepsis rules. We report the rare case of a necrotizing reaction secondary to a granulomatous reaction after a red tattoo, with a satellite node.

Case Report: A 40-year-old patient suffering from a granulomatous reaction to red dye of a large pectoral tattoo, with cutaneous and sub-cutaneous necrosis, and an infected axillary node.

Continuous gas/liquid-liquid/liquid flow synthesis of 4-fluoropyrazole derivatives by selective direct fluorination.

4-Fluoropyrazole systems may be prepared by a single, sequential telescoped two-step continuous gas/liquid-liquid/liquid flow process from diketone, fluorine gas and hydrazine starting materials.

[Gorlin syndrome: photodynamic therapy, as a useful adjunct to surgery].

Gorlin syndrome, also called nevoid basal cell carcinoma syndrome, is well known by dermatologists. Since its onset, 10 years ago, photodynamic therapy has found new applications and is now currently used to cure single or multiple basal cell carcinomas, with good results and without residual scars. We recall some of the basic principles of this technique, as well as its indications in Gorlin syndrome, which we illustrate with one case.
