Chilblain-like lesions onset during SARS-CoV-2 infection in a COVID-19-vaccinated adolescent: case report and review of literature.

Ital J Pediatr 2022 Jun 13;48(1):93. Epub 2022 Jun 13.

Department of Maternal and Child Health and Urology, Sapienza University of Rome, Rome, Italy.

Background: COVID toes or chilblain-like skin lesions have been widely reported during COVID-19 pandemic. Most cases were described in patients with negative microbiological tests for SARS-CoV-2, therefore the possible relationship with SARS-CoV-2 infection, as well as with the nowadays broadly available mRNA-based vaccination, has not been fully elucidated.  CASE PRESENTATION: We here describe the case of a 14-year-old male who developed chilblain-like skin eruptions during SARS-CoV-2 infection despite two mRNA-based vaccine doses and review the clinical and epidemiological characteristics of chilblain-like lesions as a cutaneous presentation of COVID-19 in children.

Local injection of bone-marrow derived mesenchymal stromal cells alters a molecular expression profile of a contact frostbite injury wound and improves healing in a rat model.

Burns 2022 Apr 27. Epub 2022 Apr 27.

Moscow Institute of Physics and Technology (National Research University), Institutsky per. 9, Dolgoprudny, Moscow Region 141701, Russia. Electronic address:

Introduction: Frostbite is a traumatic injury of the tissues upon low temperature environment exposure, which is characterized by direct cell injury due to freezing-thawing followed by development of an acute inflammatory process. Severe frostbite can lead to necrosis of soft tissues and loss of a limb. Mesenchymal stromal cells (MSCs) have a unique ability to modulate pathogenic immune response by secretion of paracrine factors, which suppress inflammation and mediate more efficient tissue regeneration.

The role of hyperbaric oxygen for acute traumatic ischemias.

Undersea Hyperb Med 2022 Second Quarter;49(2):233-248

Memorial Care Long Beach Memorial Medical Center, Long Beach, California U.S.

Acute traumatic ischemias are an array of disorders that range from crush injuries to compartment syndromes, from burns to frostbite and from threatened flaps to compromised reimplantations. Two unifying components common to these conditions are a history of trauma be it physical, thermal, or surgical coupled with ischemia to the traumatized tissues. Their pathophysiology resolves around the self-perpetuating cycle of edema and ischemia, and their severity represents a spectrum from mild, almost non-existent, to tissue death. Read More

Drug Deliv Transl Res 2022 Apr 21. Epub 2022 Apr 21.

Defence Institute of Physiology and Allied Sciences, Defence Research and Development Organization, Lucknow Road, Timarpur, Delhi, India.

The spectrum of cold injuries ranges from frostnip, chilblains to severe frostbite. Cold injuries occur upon prolonged exposure to freezing temperature and are pathologically a combination of ice crystal formation in the tissue resulting in inflammation, thrombosis and ischemia in the extremities, often necessitating limb amputation in extreme cases due to tissue necrosis. Severe forms of frostbite are a cause of major concern to patients as well as the treating physician. Read More

Rutgers-New Jersey Medical School, Newark, NJ, USA -

Sarcoidosis is a multiorgan disease commonly evident with skin involvement. Cutaneous manifestations occur in about 25% of sarcoid patients and are of two types: histologically specific sarcoidal infiltrations and a cutaneous reaction pattern not containing sarcoidal changes, usually erythema nodosum. Cutaneous plaques, nodules, and tumors, sometimes with disfiguring facial features are associated with pain and paresthesia. Read More
