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.
In patients with end-stage renal disease (ESRD), varicella appears to be associated with high mortality and morbidity, a recent Singapore study has shown. Researchers thus recommend vaccination in ESRD patients seronegative for varicella.
Individuals using opioid analgesics may be at an elevated risk of invasive pneumococcal disease, particularly those using long-acting, high-potency, immunosuppressive, or high-dose opioids, results of a nested case-control study show.
Apart from being tolerable and feasible, pre- and post-transplantation hepatitis C virus (HCV) treatments prevent HCV infection in non–HCV-infected recipients (ie, HCV D+/R− transplantation) of kidneys, a recent open-label nonrandomized trial in a single centre has shown.
Use of antiviral treatment for colonic cytomegalovirus (CMV) infection significantly improves short- and long-term surgery-free survival in patients with ulcerative colitis (UC), according to the results of a small-scale study.
