Efficacy and safety of leflunomide as an adjuvant drug in refractory dermatomyositis with primarily cutaneous activity.

Objectives: To evaluate leflunomide as an adjuvant drug in refractory dermatomyositis (DM) with primarily cutaneous activity.

Methods: A retrospective, single-centre, cohort study including 18 adult patients with DM (classical or clinically amyopathic DM) and cutaneous activity from 2001 to 2016 was conducted. Patients were dependent on glucocorticoid and refractory to at least two full-dose immunosuppressants/immunomodulators or presented previous adverse events with immunobiological drugs.

Undergraduate research in medical education: a descriptive study of students' views.

Background: Medical students engage in curricular and extracurricular activities, including undergraduate research (UR). The advantages, difficulties and motivations for medical students pursuing research activities during their studies have rarely been addressed. In Brazil, some medical schools have included undergraduate research into their curriculum.

Antiplasmodial, beta-haematin inhibition, antitrypanosomal and cytotoxic activity in vitro of novel 4-aminoquinoline 2-imidazolines.

A novel series of 4-aminoquinoline-containing 2-imidazolines were synthesized via a one-pot 3-component condensation reaction of amine, aldehyde and isocyanoacetate. The products were obtained in high yield as well as purity and were evaluated directly against two strains of Plasmodium falciparum and Trypanosoma brucei. Compound was the most active across all parasites with ED(50) = 3.
