BACKGROUND: The identification of a highly potent immunosuppressive/antiproliferative agent with an acceptable toxicity profile has long been a goal for the management of severe plaque psoriasis. OBJECTIVES: To investigate the efficacy and safety of sirolimus (Rapamune) for severe psoriasis when given alone or in association with cyclosporin. METHODS: In a randomized, double-blind, eight parallel group, pilot study in 24 out-patient centres in seven European countries, 150 patients, 18 years and older, with severe chronic plaque psoriasis were given sirolimus 0.5, 1.5 and 3.0 mg m(-2) daily for 8 weeks, either alone or in association with a subtherapeutic dose of cyclosporin (1.25 mg kg(-1) daily). Cyclosporin 5 mg kg(-1) daily was the positive control and cyclosporin 1.25 mg kg(-1) daily the negative control. The primary efficacy variable was the mean percentage reduction in Psoriasis Area and Severity Index (PASI). Safety assessments included monitoring of adverse events, clinical laboratory parameters and sirolimus/cyclosporin blood concentrations. RESULTS: The greatest mean percentage decreases in PASI were seen with cyclosporin 5.0 mg kg(-1) daily (70.5%) and with sirolimus 3.0 mg m(-2) daily + cyclosporin 1.25 mg kg(-1) daily (63.7%). Both groups demonstrated significantly better results than cyclosporin 1.25 mg kg(-1) daily (mean decrease 33.4%). Serum creatinine levels were significantly lower for groups with sirolimus alone and sirolimus plus reduced-dose cyclosporin when compared with cyclosporin 5.0 mg kg(-1) daily. Adverse events associated with sirolimus included thrombocytopenia (5%), hyperlipidaemia (9%), aphthous stomatitis (9%) and acne (13%), whereas adverse events associated with cyclosporin included hot flushes (12%), hyperlipidaemia (9%) and increased serum creatinine (9%). CONCLUSIONS: The concomitant administration of sirolimus with a subtherapeutic dose of cyclosporin in severe psoriasis may permit a reduction in their respective toxicities, notably cyclosporin-induced nephrotoxicity.
BACKGROUND: The diagnosis of photodermatosis is generally facilitated by the typical localization of the eruption. The causal agent can usually be identified by history taking, allowing eviction and cure. It may be difficult to find the causal agent in cases with a sequential course. The occupational and/or recreational environment may provide helpful information. We present two cases of photodermatosis related to the occupational environment. CASE REPORTS: A 50-year-old woman and a 29-year-old man were farm workers. both consulted for photoinduced eczema. The eczema was triggered by episodic manipulation of an antibiotic used widely for preparing animal feed. The standard allergy tests were negative. The photobiology exploration led to the diagnosis of photoallergy to olaquindox, a growth promotor added to animal feed. The course was favorable after eviction or protection against the product, providing a complementary proof of its triggering effect. DISCUSSION: We emphasize the contribution of photobiological explorations in difficult cases with an occupational background. Generally, these patients are unaware of the composition of the products manipulated, such as feed additives.

OBJECTIVE: To assess risk factors for erysipelas of the leg (cellulitis). DESIGN: Case-control study. SETTING: 7 hospital centres in France. SUBJECTS: 167 patients admitted to hospital for erysipelas of the leg and 294 controls. RESULTS: In multivariate analysis, a disruption of the cutaneous barrier (leg ulcer, wound, fissurated toe-web intertrigo, pressure ulcer, or leg dermatosis) (odds ratio 23.8, 95% confidence interval 10.7 to 52.5), lymphoedema (71.2, 5.6 to 908), venous insufficiency (2.9, 1.0 to 8.7), leg oedema (2.5, 1.2 to 5.1) and being overweight (2.0, 1.1 to 3.7) were independently associated with erysipelas of the leg. No association was observed with diabetes, alcohol, or smoking. Population attributable risk for toe-web intertrigo was 61%. CONCLUSION: This first case-control study highlights the major role of local risk factors (mainly lymphoedema and site of entry) in erysipelas of the leg. From a public health perspective, detecting and treating toe-web intertrigo should be evaluated in the secondary prevention of erysipelas of the leg.
BACKGROUND: CINCA syndrome (chronic infantile neurological cutaneous and articular syndrome) observed in young children associates chronic urticaria and rheumatological disorders which may cause deformation of the larger peripheral joints. Neurological signs develop later leading to severe prognosis: chronic meningitis, deafness, mental retardation. We present a bisymptomatic case which was distinctive by the absence of central nervous system involvement after 11 years of course. CASE REPORT: Since the age of six months a female child experienced chronic urticaria with nearly daily episodes. At two years limping was also observed. At nine years, the child had highly deformed knee joints giving a tumoral radiological aspect. The diagnosis of CINCA was made. At the age of 11 years, the child had normal psychomotor development and neurological and biological tests were normal. The knee deformations stablized and the child suffered little from the urticaria. DISCUSSION: This case of infantile chronic urticaria inaugurated a CINCA syndrome, a condition described in France and termed NOMID (neonatal onset multisystem inflammatory disease) in the English literature. Our case was similar to those reported in the literature showing characteristic skin, biological and rheumatological disorders. The absence of neurological involvement is exceptional and has been confirmed by regular surveillance to 11 years of age. Bone pathology showed a pseudotumoral aspect which has not been described previously.

BACKGROUND: Owing to the limited efficacy of therapy on melanoma at the stage of distant metastases, a well-tolerated adjuvant therapy is needed for patients with high-risk primary melanoma. Our hypothesis was that an adjuvant treatment with low doses of interferon alpha could be effective in patients with localised melanoma. METHODS: After resection of a primary cutaneous melanoma thicker than 1.5 mm, patients without clinically detectable node metastases were randomly assigned to receive either 3x10(6) IU interferon alpha-2a, three-times weekly for 18 months, or no treatment. The primary endpoint was the relapse-free interval. FINDINGS: 499 patients were enrolled, of whom 489 were eligible. When used as part of a sequential procedure, interferon alpha-2a was of significant benefit for relapse-free interval (p=0.038). A long-term analysis, after a median follow-up of 5 years, showed a significant extension of relapse-free interval (p=0.035) and a clear trend towards an increase in overall survival (p=0.059) in interferon alpha-2a-treated patients compared with controls. There were 100 relapses and 59 deaths among the 244 interferon alpha-2a-treated patients compared with 119 relapses and 76 deaths among the 245 controls. The estimated 3-year-relapse rates were 32% in the interferon alpha-2a group and 44% in controls; the 3-year death rates were 15% and 21%, respectively. Only 10% of patients experienced WHO grade 3 or 4 adverse events. Treatment was compatible with normal daily life. INTERPRETATION: Adjuvant therapy of high-risk melanoma with low doses of interferon alpha-2a for 18 months is safe and is beneficial when started before clinically detectable node metastases develop.

To assess the relationship between immune system and nevi, we studied two models of immunodeficiency caused by different mechanisms, i.e., virus and drug. Our rationale was that if an excess of nevi was found in these two epidemiologic models, it could be concluded that the excess was due to immunodeficiency itself rather than its cause. One hundred ten renal transplant recipients (RTR) were compared with age-, sex-, and phenotype-matched controls. Eighty four HIV-positive patients (HIV+) were compared with similarly matched controls. Nevi < 5 mm (N < 5) or > or = 5 mm (N > or = 5) were counted in three sites representative of regularly, intermittently, and never sun-exposed sites. The number of N < 5 was higher in RTR (p < 0.001) and in HIV+ (p < 0.001) than in respective controls. N > or = 5 were significantly higher only in RTR. These differences tended to be the same for all sites and persisted after adjustment for possible confounding factors. The incidence of atypical nevus was higher in RTR than in controls. Immunodeficiency seems to promote the occurrence of nevi. This supports the concept of immune surveillance of nevi and raises the question of whether sun-induced immune suppression plays a role in the development of nevi. As nevi are risk markers for melanoma, a higher incidence of melanoma could be expected in immunocompromised patients.
A case of eczema craquelé associated with gastric adenocarcinoma is reported. There are localized and generalized forms of eczema craquelé, the generalized forms differing from the localized types because they can be signs of metabolic or internal disease such as cancer. The patterns of the condition are reviewed based on the literature and personal observations.
INTRODUCTION: We describe 3 cases of hyperimmunoglobulinemia D syndrome (hyper-IgD syndrome). CASES REPORT: As the 2 first cases are conventional with an onset in childhood, the third one appeared later suggesting possibility of acquired syndrome. The 3 cases presented with one or several skin eruptions during febrile attacks. COMMENTS: Up to now, 64 cases of this syndrome have been described. Skin lesions are observed in 80 p. 100 of patients. In this particular clinical context, they must lead to the diagnosis. This 3 cases and the review of literature show that skin manifestations are polymorphic, transient, not very symptomatic and not correlated to IgD rates. Histological examination may reveal urticarial reaction with leucocytoclasic vasculitis, where IgD could directly or not interact.

BACKGROUND: Dermatofibrosarcoma is a tumor relatively ignored in childhood. CASE REPORT: A 11 year-old boy was referred because he suffered from a tumor of the neck, which had progressively developed after a cervical traumatism occurring 4 years earlier. Examination showed a tumor moderately infiltrated, attached to the overlying erythematous skin. Biopsy showed ill-limited dermal and hypodermal proliferation of fusiform cells with a storiform arrangement. Two successive excisions were necessary and the patient is well 2 years later. CONCLUSION: This case confirms responsibility of previous traumatism, progressiveness of course and necessity of large excision.
INTRODUCTION: Primary erythermalgia is a rare acrosyndrome due to paroxystic arteriolar dilatation of extremities that become red and congested with warmth and burning sensation or pain. OBSERVATION: We report herein the observation of a primary erythermalgia affecting 3 degrees in the same family (grandfather, uncle/mother, and children with early onset at 6 years): pizotifene, an antiserotoninergic drug proved to be effective in mother and 14-year-old child who had never drawn benefit from any previous treatment. DISCUSSION: Several etiologies may be responsible for erythermalgia according to the clinical type: primary erythermalgia with pediatric onset, and secondary erythermalgia as a reaction to myeloproliferation, other diseases, drug or heavy metal poisoning. Pathophysiology of primary erythermalgia is not clearly understood and the main concern is therapy: in this respect, pizotifene deserves to be considered as a valuable possibility.
A patient with an acquired pigmentation related to lichen planus pigmentosus is described. Features of acrokeratosis of Bazex were associated, related to a head and neck carcinoma. Both cutaneous conditions disappeared after treatment of the neoplasia. Diagnostic criteria of lichen planus pigmentosus are reviewed. The paraneoplastic nature of this original observation of lichen planus pigmentosus is discussed.
