Over the past few years, better understanding of the explicit pathomechanism of alopecia areata provides new treatment opportunities for effective therapy of the disease, which may revolutionize therapeutic strategies. This exceedingly heterogeneous disease with unpredictable outcome, severely affects the quality of life. Currently, there are no standardized treatment protocols approved by the European Medicines Agency (EMA), resulting a challenge for the therapists in the choice of treatment.In this paper, the authors summarize recent and emerging therapies for severe cases of alopecia areata.

Herpes simplex virus (HSV) infection is extremely common in both children and adults. HSV has two serotypes, HSV-1 primarily causes orolabial while HSV-2 anogenital symptoms. In recent decades there has been a change in the predilection to affected anatomical regions in both serotypes, participation of HSV-1 serotype in genital infections is increasing. The primary acquisition of HSV-1 has increasingly shifted from early childhood to young adulthood over the past years. Asymptomatic infection and virulence factors are crucial in the spread of the virus. Cutaneous symptoms, erosions and crusted lesions after vesicular stage present various differential diagnostic problems in the involved regions. Early diagnosis and timely adequate therapy in serious cases are essential as well as suppressive treatment of recurrent symptoms. Several clinical trials are underway to develop more effective antivirals. Vaccination against HSV would be a key to prevent latent infections, transmission and reactivation. The authors present characteristics of HSV, age-specific clinical manifestations, differential diagnostic problems and adequate treatment strategies.
