Venous insufficiency of the legs is a frequent and insidious disorder which, through its consequences' cascade, lead to some cutaneous microangiopathy with relative ischemia. Chronic leg ulcer is the late issue of the process accompanied by varied medical and socio-economic aspects. The pathogeny of the cutaneous lesions is directly related to alterations in hemorrheology and leukocyte adhesion inside capillaries. Elastic contention and some venotropic drugs exert preventive effects on the development of leg ulcers. They also bring some therapeutic improvement of the symptoms of leg heaviness. [less ▲]

The pathogenesis of venous ulcers is complex. A critical bacterial colonization may play a harmfull role. The use of topical antibiotics is unwise, and that of antiseptics is still a matter of debate. Some authors contend that antiseptics mitigate wound healing through a toxic effect upon keratinocytes and fibroblasts. However, sound arguments support the paradoxical concept of beneficial cytotoxicity of antiseptics in the treatment of chronic venous ulcers. [less ▲]

Hair shedding and hair thinning have been reported to be affected by dandruff and seborrhoeic dermatitis. The present study was conducted in 150 men presenting with telogen effluvium related to androgenic alopecia associated with dandruff. They were randomly allocated to three groups receiving each one of the three shampoos in the market containing either 1% ketoconazole (KTZ), 1% piroctone olamine (PTO) or 1% zinc pyrithione (ZPT). Shampoos had to be used 2-3 times a week for 6 months. Hair shedding during shampoo was evaluated semiquantitatively. Hair density on the vertex was evaluated on photographs using a Dermaphot. Trichograms were used for determining the anagen hair percentage and the mean proximal hair shaft diameter using computerized image analysis. The sebum excretion rate (SER, mug cm(-2) h(-1)) was also measured using a Sebumeter((R)). The three treatments cleared pruritus and dandruff rapidly. At end point, hair density was unchanged, although hair shedding was decreased (KTZ: -17.3%, PTO: -16.5%, ZPT: -10.1%) and the anagen hair percentage was increased (KTZ: 4.9%, PTO: 7.9%, ZPT: 6.8%). The effect on the mean hair shaft diameter was contrasted between the three groups of volunteers (KTZ: 5.4%, PTO: 7.7%, ZPT: -2.2%). In conclusion, telogen effluvium was controlled by KTZ, PTO and ZPT shampoos at 1% concentration. In addition, KTZ and PTO increased the mean hair shaft thickness while discretely decreasing the sebum output at the skin surface. [less ▲]

Some cutaneous functions of importance are governed by periodical variations according to the nycthemeral timing. Similarly to other organs, the skin is under the influence of a coherent organisation of circadian and nythemeral rhythms modulating various biological cycles which usually display a wide amplitude. The cutaneous biorhythms in humans suggest that during daylight the skin boosts diverse protective functions with regard to environmental threats. In the evening and at night, the skin increases its renewal and diverse metabolic processes. Biorhythms in the skin which are in line with the organism's needs, merit to be recognized. Chronophysiology, chronopathology and clinical chronopharmacology may help reach optimal therapeutic decisions. [less ▲]

Slowing down ageing is a goal for a large part of the population. Some mercantile claims hold out bright prospects to DHEA. The effects of this hormone manifest themselves after intracrine conversion. In the skin, sebaceous glands enlarge and seborrhoea increases in post-menopausal women. No other effect is clinically discernable on the skin. At this level, DHEA does not show efficacy comparable to that of other anti-ageing compounds. [less ▲]

A presumed melanoma metastasis is sometimes found without any evidence for the primary neoplasm. Such an orphan metastasis merits a complementary exploration. Searching for the primary melanoma must then be performed using non invasive and clinically oriented methods. Beside a thorough skin examination, otorhinolaryngological, ophtalmic and gynecologic searches are recommended. In addition, paraclinical investigations are conducted according to the metastatic location, the gender and the functional complaints of the patient. The prognosis of these orphan metastases is not more dramatic than when the primary lesion is identified. Therapies are similar to those proposed in the classical presentation of the disease.

There exists several clinical types of scleroderma. Most of them show cutaneous manifestations. Skin involvement may be isolated (morphea) or be part of a multi-organ systemic disease. Objective non-invasive functional methods are useful in order to better assess the severity and evolution of the disease and the effects of treatments. Measurements of the thickness and mechanical properties of the skin as well as the visualization of the cutaneous blood flow prove to be informative. [less ▲]

INTRODUCTION: We report a case of severe pustular vasculitis most probably due to losartan (Cozaar) which is an antihypertensive drug inhibiting the receptors for angiotensin II. CASE REPORT: A 64-year-old woman, suffering from hypertension, developed a widespread and rapidly evolving bullous and pustular eruption without any other clinical sign. Leucocytoclastic vasculitis and junctional blisters were present with deposits of both IgA and IgG at these sites. Withdrawal of losartan, which was the only drug taken by the patient, and tapered corticotherapy cleared the lesions. The rash left a prominent mottled hyperpigmentation. It did not recur during the following months despite the presence of antineutrophil cytoplasmic antibodies. DISCUSSION: So far only a few cutaneous side effects have been reported following losartan intake. This drug was the likely culprit in the present case. Vasculitis was extremely severe and polymorphous. [less ▲]

BACKGROUND: Cutaneous sensorial perception is complex and proves to be difficult to quantify. Skin sensitivity to mechanical distension is largely unexplored. We have developed an original method aimed at quantifiying these physiological parameters.VOLUNTEERS AND METHODS: The study was performed on 24 adult volunteers aged 20 to 50 years. A Cutometer SEM 474 equipped with 2 and 4 mm diameter probes was used to exert a progressive or a steep suction on the cheeks. The intensities of both the suction and the skin deformation observed at the earliest moment the traction was perceived by the volunteers were recorded.RESULTS: The liminar sensorial detection under progressive suction force was 1.5 times lower when using the 4 mm probe than the 2 mm probe. Suction necessary for liminar sensation was 7 times lower under steep suction than in response to the progressive mode. The skin deformation corresponding to the liminar sensorial perception was almost constant (C=0.5 p. 100) for each subject. By contrast, a large inter individual heterogeneity unrelated to age was present.COMMENTS: Sensitivity of facial skin to stretching can be explored using a precise suction method. Perception is more related to the rate of traction than to the surface area submitted to suction. Cutaneous deformation, nearly constant for each individual, appears to be the main parameter. Steep and progressive suctions appear to stimulate distinct types of mechanoreceptors. The presently described method can be applied in cosmetology and in functional investigation of various diseases such as diabetes, acromegaly and atopic dermatitis among others. [less ▲]

BACKGROUND: Dye mixtures containing henna, P-phenylenediamine (PPD), and indigo are applied to the skin in various parts of the world for religious purposes, social recognition or fun. AIM: To identify eventual allergens responsible for contact sensitization to skin decoration in three young children. Lesions remained strictly limited to the site painted during the summer holiday. None of the children had a previous history of contact dermatitis, but two of them suffered from severe seasonal allergic rhinoconjunctivitis. FINDINGS: Patch testing revealed severe contact hypersensitivity to PPD in all three patients, and one child presented a positive prick test to 1% henna in water. The eruptions resolved following spontaneous elimination of the dyes and topical applications of corticosteroids, but left residual depigmentation. CONCLUSION: PPD is the main allergen identified in allergic reactions to decorative skin paintings. [less ▲]

BACKGROUND: Positron emission tomography (PET scan) using fluorodeoxyglucose (FDG) is increasingly recognized as a reliable diagnostic method to detect metastases of malignant melanoma (MM). OBJECTIVE: To compare the diagnostic performance of 18-FDG PET scan to that of conventional imaging. METHODS: A total of 28 assessments were conducted in 24 patients at risk of metastatic MM. Results: The diagnostic accuracy was over 80% and similar for PET scan and conventional imaging. CONCLUSION: Both the specificity and sensitivity of PET scan are high although not perfect. Confrontation of data with anatomical location and clinicopathological findings remains mandatory. [less ▲]

The Mosan Study Group of Pigmented Neoplasms was founded about 15 years ago. It has collected more than 20.000 cutaneous malignancies including melanoms and basal and squamous cell carcinomas. The incidence of these cancers in on the rise in Wallonia. In particular, malignant melanoms represent a spectrum of emerging cancers characterized by a proteiform biological outcome. They mostly affect young women. The major risk factor appears to be iterative and unwise ultraviolet exposures. The prevention of malenomas is basically founded on such a dogma and accordingly relies on sunscreens. However, controversies about their beneficial effects are rife and fueled by axiomas and contradictory sophisms. At the exception of surgery, the therapeutic options for the diverse types of melanomas do not yet fulfill the scope of evidence-based medicine. [less ▲]
