[more ▼] Palmoplantar keratodermas affect a vast group of the population. Their origin is genetic or acquired. They represent manifestations of several distinct diseases. The precise semiologic examination is important for elucidating the differential diagnosis.

[more ▼] A pruritic vesicular, pustular or squamous eruption confined to the lateral aspect of fingers or toes corresponds to the overall pattern of dysidrosis. Such a clinical pattern is defined by its peculiar topography. It is encountered in diseases resulting from various etiologies. Thus, conceptually, dysidrosis is a common clinical aspect shared by diverse disorders related to different etiologies and pathomechanisms. The dermatopathological assessment and the patch test procedure shed some light on this nosological diversity. Allergic contact dermatitis, irritation dermatitis, mycids, alterations of acrosyringia, and drug or food reactions are eventually involved in this process. However, most cases of dysidrotic dermatoses do not disclose their origins and they remain idiopathic. [less ▲] Detailed reference viewed: 41 (3 ULg)L'image du mois.

[more ▼] Some skin disorders typically share in common a hypochromic or achromic aspect. The diagnostic approach relies on a directed evaluation of the medical history and a careful clinical examination. In addition, the cyanoacrylate skin surface biopsy helps establish the diagnosis.

[more ▼] SYNOPSIS: Skin colours are notoriously different between individuals. They are governed by ethnicities and phototypes, and further influenced by a variety of factors including photoexposures and sustained mechanical stress. Indeed, mechanobiology is a feature affecting the epidermal melanization. High-resolution epiluminescence colorimetry helps in deciphering the effects of forces generated by Langer's lines or relaxed skin tension lines on the melanocyte activity. The same procedure shows a prominent laddering pattern of melanization in striae distensae contrasting with the regular honeycomb pattern in the surrounding skin.

[more ▼] Xerosis represents a physiological response of the stratum corneum (SC) to environmental threats. The influence of the environmental dew point (DP) is not fully understood. This parameter is the air temperature at which the relative humidity is maximum. This study aimed to assess the relationship between the environmental DP and the water-holding capacity of the skin and lower lip vermilion. For comparison, SC property was evaluated after occlusive application of cooled and uncooled hydrogel pads. Electrometric measurements using a dermal phase meter (DPM) device were performed on the back of the hands, the cheeks and the lower lip of 40 healthy menopausal women. Assessments were performed in the outdoor conditions during winter and spring. The same measurements were recorded after hydrogel pads, at room temperature or cooled to 4 degrees C, were placed for 15 min on the test sites. The environmental DP was recorded at each evaluation time. The SC water-holding capacity was discretely influenced by the DP. In the open-air environmental conditions, a positive linear relationship was found on the cheeks between the DP and DPM values. The relationship was weaker on the lips. Conversely, a consistent increase in DPM values was recorded immediately after removal of the cooled and uncooled hydrogel pads. The observations made in the open-air testing conditions are consistent with the predicted events following the Arrhenius law. By contrast, the combination of cooling and occlusion by the hydrogel pads is responsible for the reverse effect on the SC. [less ▲] Detailed reference viewed: 11 (1 ULg) |
