WARTS - CUTANEOUS
Cutaneous warts, also called verrucae, are benign proliferations of skin caused by human papillomavirus (HPV).
Most common warts on the hands and feet are due to HPV types 1, 2, 4, 27 & 57.
HPV is usually transmitted by contact with skin of an infected individual or by transmission of virus living in warm moist environment.
Autoinoculation may occur from traumatizing lesions by biting or scratching.
Incubation period is unknown but may range from months to years.

Patients with a first episode of Clostridium difficile infection (CDI) are likely to respond to treatment with fidaxomicin with no recurrences, a recent study has shown. On the other hand, those with prior CDI episodes are less likely to respond, especially with >1 prior episode, and more likely to recur, which suggests a greater clinical benefit of fidaxomicin earlier in the course of CDI.
