We report a 16-year-old girl with neonatal progeroid features and congenital lipodystrophy who was considered at birth as a possible variant of Wiedemann-Rautenstrauch syndrome. The emergence of additional clinical signs (marfanoid habitus, severe myopia and dilatation of the aortic bulb) lead to consider the diagnosis of the progeroid variant of Marfan syndrome. A de novo donor splice-site mutation (c.8226+1G>A) was identified in FBN1. We show that this mutation leads to exon 64 skipping and to the production of a stable mRNA that should allow synthesis of a truncated profibrillin-1, in which the C-terminal furin cleavage site is altered. FBN1 mutations associated with a similar phenotype have only been reported in four other patients. We confirm the correlation between marfanoid phenotype with congenital lipodystrophy and neonatal progeroid features (marfanoid-progeroid-lipodystrophy syndrome) and frameshift mutations at the 3' end of FBN1. This syndrome should be considered in differential diagnosis of neonatal progeroid syndromes. [less ▲]

BACKGROUND: Climacteric skin aging affects certain biophysical characteristics of facial skin. The purpose of the present study was to assess the symmetric involvement of the cheeks in this stage of the aging process. METHODS: Skin viscoelasticity was compared on both cheeks in premenopausal and post-menopausal women with indoor occupational activities somewhat limiting the influence of chronic sun exposure. Eighty-four healthy women comprising 36 premenopausal women and 48 early post-menopausal women off hormone replacement therapy were enrolled in two groups. The tensile characteristics of both cheeks were tested and compared in each group. A computerized suction device equipped with a 2 mm diameter hollow probe was used to derive viscoelasticity parameters during a five-cycle procedure of 2 seconds each. Skin unfolding, intrinsic distensibility, biological elasticity, and creep extension were measured. RESULTS: Both biological elasticity and creep extension were asymmetric on the cheeks of the post-menopausal women. In contrast, these differences were more discrete in the premenopausal women. CONCLUSION: Facial skin viscoelasticity appeared to be asymmetric following menopause. The possibility of asymmetry should be taken into account in future studies of the effects of hormone replacement therapy and any antiaging procedure on the face in menopausal women. [less ▲]

Le vieillissement de la peau se marque à terme par une atrophodermie, parfois sévère. La corticothérapie, qu’elle soit systémique ou topique, exerce un effet atrophiant qui copie l’effet du grand âge. Cet état d’atrophodermie a été décrit comme la «peau transparente» il y a une quarantaine d’années, et il a reçu plus récemment la nouvelle dénomination de dermatoporose. Il est connu de longue date que cet état entraîne des conséquences cliniques parfois majeures qui conduisent à des lésions diverses sous forme de purpura de Bateman, de cicatrices stellaires, et de plaies faisant suite à des traumatismes mineurs.

Background: The Ehlers-Danlos syndrome (EDS) represents a heterogenous group of heritable connective tissue disorders chiefly characterized by joint laxity, increased skin distensibility and connective tissue fragility. Each EDS type corresponds to a multisystemic disorder with widespread implications. Physicians evoke the EDS diagnosis in presence of some typical cutaneous signs, such as atrophic scars and frequent hematomas. Methods: To revisit the transmission electron microscopy support from skin biopsies when screening EDS in gynecology-obstetrics. Results: EDS women commonly suffer from a series of gynecologic and obstetric disorders. Dermal ultrastructural changes are keynote features suggesting some EDS types. Conclusion: Gene mutations are mostly identified in the classic and vascular EDS types, but only in sporadic cases of the hypermobile EDS type which apparently represents the most frequent type. Dermal ultrastructural changes represent relevant diagnostic clues for the practitioner. Preconception counseling about possible complications is welcome. Management requires precise diagnosis of the EDS type. [less ▲]

For more than 70 years, the watchful-waiting management of infantile strawberry hemangiomas still prevails in a number of clinical settings. This concept appears now outdated since the introduction of well-suited beta-blockers, as well as noncoherent light and laser therapies. The aim of this work was to revisit the effect of intense pulsed light (IPL) therapy on infantile hemangioma. Information was collected from the peer-reviewed literature and illustrated by personal cases. When applied early in the evolution of infantile hemangiomas, IPL treatment stops the growth phase and induces regression with minimal cosmetic adverse effects and psychological damage. Initiating an adequate treatment is important because damage due to hemangiomas can be diminished by a timely and adequate approach. Beta-blockers have revolutionized the therapeutic strategy of infantile hemangiomas. The flash light therapy (IPL) represents an alternative therapy for some patients. [less ▲]

BACKGROUND: The gravitational syndrome resulting from venous pressure elevation occasionally develops on the legs during pregnancy. The limb tends to enlarge and become stiffer. The body contours are altered. AIMS: To assess incipient gravitational edema due to chronic venous insufficiency using measurements of the skin tensile strength. METHOD: A total of 21 women aged 28-37 years were enrolled in the study. Evaluations were made twice in each subject following an alternate use and avoidance of daytime elastic contention. Skin viscoelasticity was measured on the mid portion of the calves using a computerized suction device. RESULTS: The discretely increased consistency of skin showing abnormal rheological characteristics at the site of incipient gravitational edema was significantly improved by contention therapy. Under progressive suction measurements, both skin distensibility, biologic elasticity and hysteresis were increased after wearing tight stockings. The biologic elasticity appears to be the most sensitive parameter pointing to the diagnosis of gravitational syndrome. CONCLUSION: Noninvasive measurements of the skin viscoelasticity, particularly the biologic elasticity, represent an objective assessment of both early gravitational edema and its control by contention therapy.

The frontier between the human body and the environment is largely represented by the stratum corneum. It is obvious that the skin aspect on some body sites appears dry and rough in some predisposed individuals during winter season. The reductions in the outdoor temperature, ambient moisture and dew point are the main physical factors involved in this process. We present the aspects seen under ultraviolet light and scanning electron microscopy. Keywords : Stratum corneum - Dew point [less ▲]

Some recently introduced targeted treatments in cancerology are responsible for adverse effects on the skin. These events alter the patient well-being. Adequate dermocosmetic management allows to curb the unwanted skin conditions without interfering with the targeted therapeutic effects. However, evidence-based support for using dermocosmetic products as adjunctive cancer treatment remains scarce. It remains nonetheless that the clinical perception is unanimously favourable for such procedure. [less ▲]

Basal cell carcinomas (BCCs) are the most frequent human cancer. Over 90% of all BCCs have a mutation in patched homologue 1 (PTCH 1) or smoothened (SMO), two conducting proteins of the Hedgehog (Hh) pathway. They rarely progress deeply and metastasize; however, if they do, these advanced BCC become amenable to treatment by inhibiting the Hedgehog and the P13K–mTOR pathways. Such innovative drugs include vismodegib, cyclopamine, itraconazole, everolimus and a few other agents that are in early clinical development. [less ▲]
