In vivo evaluation of facial papule dermatoses with reflectance confocal microscopy in children.

Skin Res Technol 2022 Jun 21. Epub 2022 Jun 21.

Department of Dermatology, Tianjin Children's Hospital, Tianjin, China.

Background: Molluscum contagiosum (MC), milia, keratosis pilaris (KP), verruca plana (VP), seborrheic keratosis (SK), and juvenile xanthogranuloma (JXG) are common papule dermatoses on the face of children that have a similar appearance. In vivo evaluation of facial papule dermatoses with reflectance confocal microscopy (RCM) is helpful in the diagnosis of these ambiguous lesions in children. The purpose of this study was to clarify the RCM characteristics of MC, milia, KP, VP, SK, and JXG and explore the clinical application value of RCM for these common facial papule dermatoses.

Keratosis pilaris and filaggrin loss-of-function mutations in patients with atopic dermatitis - Results of a Finnish cross-sectional study.

J Dermatol 2022 May 26. Epub 2022 May 26.

Helsinki University Hospital, Skin and Allergy Hospital, Helsinki, Finland.

Keratosis pilaris (KP) associates with epidermal barrier defects in atopic dermatitis (AD) but its role in disease severity and concomitant atopic diseases seems to vary between populations. We performed a cross-sectional observational study with 502 randomly selected AD patients of a Finnish tertiary health care center. At a single clinical examination, disease severity (Rajka Langeland severity score and EASI), clinical signs and patient history were evaluated and total IgE levels and frequent filaggrin (FLG) loss-of-function mutations were investigated.

Keratosis pilaris rubra successfully treated with topical sirolimus: Report of a case and review of the literature.

Pediatr Dermatol 2022 Mar 1. Epub 2022 Mar 1.

Department of Dermatology, University of Minnesota, Minneapolis, Minnesota, USA.

Keratosis pilaris rubra (KPR) is a subtype of keratosis pilaris (KP) presenting with numerous "grainlike" follicular papules in a background of confluent erythema most often affecting the face and upper extremities with persistence beyond puberty. Treatment has remained challenging with inconsistent benefit from topical therapies such as emollients, keratolytics, corticosteroids, and retinoids, though case reports documenting success with pulsed dye laser therapy have been found. We present a case of KPR in a 15-year-old boy who was successfully treated with topical sirolimus 1% cream. Read More

de Duve Institute, UCLouvain, 1200 Brussels, Belgium. Electronic address:

We describe a genetic syndrome due to PGM2L1 deficiency. PGM2 and PGM2L1 make hexose-bisphosphates, like glucose-1,6-bisphosphate, which are indispensable cofactors for sugar phosphomutases. These enzymes form the hexose-1-phosphates crucial for NDP-sugars synthesis and ensuing glycosylation reactions. Read More

Cutaneous Manifestations of Nutritional Excess: Pathophysiologic Effects of Hyperglycemia and Hyperinsulinemia on the Skin.

Cutis 2021 Feb;107(2):74-78

Mr. Svoboda is from the Virginia Tech Carilion School of Medicine, Roanoke. Dr. Shields is from the Department of Dermatology, University of Wisconsin School of Medicine and Public Health, Madison.

Hyperglycemia is defined by excess blood glucose and, when persistent, may lead to prediabetic and diabetic states. Insulin is a hormone produced by the beta cells of the pancreas in response to elevated blood glucose. Dysregulated insulin secretion or clearance results in hyperinsulinemia, which also is closely associated with type 2 diabetes mellitus (T2DM) and metabolic disturbances. Read More
