Histiocytes belong to distinct groups of cells. Similarly, histiocytoses represent some pathologic expressions of the various histiocyte lineages recognized by their distinct phenotypes. The recognition of four major histiocytosis types relies on the distinction between monocytes-macrophages, dermal dendrocytes, Langerhans cells and the so-called indeterminate cells. Each of these groups exhibits a distinctive clinical and histological presentation. The risk of internal involvement, the prognosis and therapy are different as well. The diagnostic mainly relies on the clinico-pathologic assessment, and more particularly on the combination of histological, immunohistochemical and ultrastructural examinations. [less ▲]

A series of gastro-intestinal diseases exhibits some connection with various cutaneous lesions. Some skin manifestations are clinically or histologically evocative, while others lack specificity. These manifestations can occur in overt digestive disease or be the clue for a silent one. A careful skin examination can thus reveal some inflammatory or neoplastic diseases of the gastro-intestinal tract, a malabsorption syndrome or food intolerance. [less ▲]

BACKGROUND: Radiotracer and blue-dye lymphatic mapping is a recommended combined method to guide sentinel lymphadenectomy and full regional lymph node dissection in selected patients with cutaneous melanoma. OBJECTIVE: To evaluate the diagnostic accuracy and the prognostic value of gamma-probe-directed lymphatic mapping in cutaneous melanomas. METHODS: Sixty-five stage I and II melanoma patients underwent gamma-probe-directed lymphatic mapping. Sentinel lymph nodes were studied by both conventional and immunohistochemical stainings. The median follow-up was 11 months. RESULTS: Sensitivities of preoperative and intraoperative sentinel lymph node detection were 100 and 98%, respectively. Only 1 failure of detection and 1 missed same-basin metastasis were experienced in the axillary and cervical areas, respectively. Eleven patients (16.9%) had sentinel node metastases leading to adjuvant therapy. CONCLUSION: Gamma-probe-directed lymphatic mapping is useful for staging melanoma. However, in the expectation of a more specific identification of the sentinel lymph node, the standard protocol remains recommended for exploring the axillary and cervical areas. The histological examination supported in some cases by immunohistochemistry remains mandatory in all cases. [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 ▲]

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.

BACKGROUND: The corneofungimetry bioassay was designed as a unique model predicting the efficacy of topical and oral antifungals in dermatomycoses. OBJECTIVE: In this 2-step study performed in two groups of 15 volunteers, corneofungimetry was used to compare the effect of 5-day b.i.d. treatments with 2% ketoconazole and 1% terbinafine creams. METHODS: The bioassay was performed using 10 isolates of each of the 3 fungi Trichophyton rubrum, T. mentagrophytes var. interdigitale and Candida albicans put to grow on human stratum corneum. Controls were stratum corneum either untreated or enriched in propylene glycol contained in an unmedicated vehicle. Quantitative assessments were made using both Euclidean and fractal geometry parameters. RESULTS: In comparison with untreated stratum corneum, the fungitoxic activity of the 2% ketoconazole and 1% terbinafine formulations was obvious and similar against dermatophytes. By contrast, 2% ketoconazole was significantly more active against C. albicans than 1% terbinafine. The propylene-glycol-containing vehicle did not exhibit a significant effect upon the dermatophyte growth. Positive linear correlations were yielded between the extent area and the fractal dimension D of dermatophyte mycelia. By contrast, D appeared unrelated to the relative area of dermatophyte growth compared to controls. CONCLUSION: The combination of Euclidean and fractal analyses improves the information provided by the corneofungimetry bioassay. Creams containing 2% ketoconazole and 1% terbinafine appear equally effective against dermatophytes while the former is more potent against Candida albicans. [less ▲]

BACKGROUND: Some antibiotics represent a mainstay in acne treatment. However, studies comparing their efficacies are rare. AIM: To evaluate the clinical and in vivo antibacterial effect of lymecycline and minocycline at different dosages. METHOD: Eighty-six patients with moderate to severe acne were enrolled in a randomized, double-blind, intent-to-treat study comparing in three parallel groups the effect of (1) lymecycline 300 mg daily for 12 weeks, (2) minocycline 50 mg daily for 12 weeks and (3) minocycline 100 mg daily for 4 weeks followed by 50 mg daily for 8 weeks. Evaluations were made at the screening visit and at five on-treatment visits. They consisted of clinical counts of acne lesions and evaluations of bacterial viability using dual flow cytometry performed on microorganisms collected from sebaceous infundibula by cyanoacrylate strippings. RESULTS: Patients receiving minocycline 100/50 mg had the best clinical outcome, particularly in the reduction of the number of papules. By the end of the trial, the microbial response to minocycline 100/ 50 mg was also superior to either of the other two treatments. There were less live and more dead bacteria. CONCLUSION: In this trial, minocycline 100/50 mg was superior for the treatment of inflammatory acne when compared to lymecycline 300 mg and minocycline 50 mg. [less ▲]

Onychomycosis represents a stubborn problem for the clinician facing up to the realities of antifungal treatments. There are obvious discrepancies between data given by in vitro antifungal testings, pharmacodynamics and pharmacokinetics, and those gathered from clinical experience. This critical review is an attempt at bridging the gap between in vitro and in vivo information about oral antifungals that aim to treat onychomycoses. Common sense shows that the in vitro concept of fungicidy cannot be simply extrapolated into clinical practice. Indeed, chlamidoconidia and arthroconidia present in vivo are much more resistant to antifungals than hyphae. Corneofungimetry may be a realistic bioassay in predicting antifungal activity in human infections. Boosting hyphae growth from conidia while taking antifungals is a new and appealing treatment modality that deserves controlled study. [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 ▲]
