Cutaneous protothecosis: a new case and review of Brazilian patients.

Protothecosis is a rare but emerging infectious disease, caused by algae from the genus Prototheca. It presents predominantly as cutaneous lesions and poses a diagnostic challenge owing to its diverse clinical presentation. Typically, it occurs in exposed areas of the skin, associated with trauma.

Coexistence of onychomycosis and nail psoriasis and its correlation with systemic treatment.

Background: Epidemiological studies indicate that onychomycosis may affect up to 79% of psoriatic patients. Onychomycosis in psoriatic patients is more commonly caused by yeasts comparing with non-psoriatic.

Objectives: Evaluate the prevalence of fungi in nail psoriasis.

Simulation-Based Structured Education Supports Focused Neonatal Cranial Ultrasound Training.

Objectives: Brain injury in preterm neonates may cause clinical deterioration and requires timeous bedside diagnosis. Teaching cranial ultrasound (US) skills using fragile preterm neonates is challenging. The purpose of this study was to test the effectiveness and feasibility of using task-trainer computer-based simulators and US-suitable cranial phantoms in combination with teaching sessions in teaching novices to perform focused cranial US evaluations for identifying substantial intraventricular hemorrhage.
