Coniosporium epidermidis sp. nov., a new species from human skin

Coniosporium epidermidis sp. nov. is described from a superficial skin lesion with blackish discolouration in an 80-yr-old Chinese patient. The species produces dark, thick-walled, inflated, reluctantly liberating arthroconidia without longitudinal septa. Sequences of the ribosomal operon, as well as of the translation elongation factor 1-α support its novelty. The species is found in a lineage basal to the order Chaetothyriales, amidst relatives from rock, but also species repeatedly isolated from human skin and nails and eventually causing mild cutaneous infections. Coniosporium epidermidis is consistently found on humans, either asymptomatic or symptomatic. The species indicates a change of life style towards human pathogenicity, which is a recurrent type of ecology in derived Chaetothyriales. Superficial and cutaneous infection by melanized fungi is a new category in dermatology

Low and high body mass index in hidradenitis suppurativa patients—different subtypes?

Introduction: Overweight is a well-established risk factor for hidradenitis suppurativa (HS). In this cross-sectional study, we compare HS patients with a high body mass index (BMI) with HS patients with a low BMI to investigate differences in disease characteristics. Materials and method: Patients were recruited from 17 dermatological centres from four continents. A total of 246 patients with a BMI below 25 were compared to 205 patients with a BMI of above 35. Results: Patients with a high BMI suffered more severe disease (Hurley, physician global assessment, number of areas affected and patient-reported severity (PRS), P < 0.001 for all). There was no difference in smoking (P = 0.783) nor in family history (P = 0.088). In both low and high BMI patients, early onset of HS was a predictor of positive family history (P < 0.001, for each). For low BMI patients, an increase in BMI significantly increased PRS (P < 0.001). For patients with a high BMI, number of pack-years significantly increased PRS (P = 0.001). Cluster analysis of eruption patterns was location specific for low BMI patients but severity specific for high BMI patients. Discussion: Patients with a low and high BMI could represent two clinically different subtypes. We suggest a non-linear relationship between BMI and impact of HS. As patients go from a low BMI patient to a high BMI patient (or from high to low), eruption patterns and risk factors may change.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
