Acyclovir for treating varicella in otherwise healthy children and adolescents

Varicella gangrenosa: A rare chickenpox complication

Varicella gangrenosa is a rare but life-threatening dermatological complication of infection with varicella-zoster virus. A healthy 37-year-old male who had been diagnosed with varicella 20 days back was admitted to our hospital with complaints of fever and painful necrotic skin lesions. Physical examination revealed multiple round to oval ulcers covered with eschar predominantly over arms, lower limbs, back of trunk and flanks. Streptococcus pyogenes and Staphylococcus aureus grew in wound culture. Biopsy revealed ulceration and necrosis of epidermis, and edema, hemorrhage and granulation tissue formation involving the dermis and subcutaneous tissue. The patient was treated with acyclovir - parenteral followed by oral, antibiotics and supportive measures. The lesions healed and he was discharged after 20 days. We report this case to draw attention to the fact that varicella gangrenosum, even though a rare complication, may occur in the lesions of chicken pox and that the survival of patient depends on early diagnosis and aggressive treatment.

Emerging and Re-emerging Infections in Children: COVID/ MIS-C, Zika, Ebola, Measles, Varicella, Pertussis ... Immunizations

The role of the emergency provider lies at the forefront of recognition and treatment of novel and re-emerging infectious diseases in children. Familiarity with disease presentations that might be considered rare, such as vaccine-preventable and non-endemic illnesses, is essential in identifying and controlling outbreaks. As we have seen thus far in the novel coronavirus pandemic, susceptibility, severity, transmission, and disease presentation can all have unique patterns in children. Emergency providers also have the potential to play a public health role by using lessons learned from the phenomena of vaccine hesitancy and refusal.

Evidenzbasierte Therapie von Herpes-Virus-Erkrankungen der Haut

Six questions regarding varicella-zoster virus-related skin diseases are addressed. The Cochran Library, MEDLINE, Clinical Evidence and several guideline providers were searched for evidence. The level of evidence in papers was appraised according to the Oxford Centre for Evidence-based Medicine Levels of Evidence. The current evidence for antiviral therapy of chickenpox in immunocompetent children, adults and pregnancy, recommendation of varicella vaccination, effect of time of initiation of antiviral therapy in acute zoster as well as route of treatment with regard to onset of post-zoster neuralgia are covered.
