A large number of drugs may be responsible for the development of nail changes. Sirolimus is an immunosuppressive drug recently developed in organ transplantation. Herein, we evaluate sirolimus-induced nail abnormalities in renal transplant recipients. ⋯ This study reports a new drug-induced onychopathy. Responsibility of sirolimus is highly suggested. The main pathogenesis hypothesis to explain these nail alterations is inhibition of EGF (epidermal growth factor) pathway by sirolimus.

Parkes-Weber syndrome is usually described as a sporadic form of osteohypertrophic angiodysplasia. However, family forms of Klippel-Trenaunay syndrome have been described. We report the first familial case of Parkes-Weber syndrome. ⋯ This is the first observation of a familial case of Parkes-Weber syndrome in first cousins. Vascular malformations are transmitted in autosomal dominant fashion in the majority of infected families but with incomplete penetrance and variable expressivity. Symptoms appeared to worsen from generation to generation. In each generation of this family, we noted the presence of hemangiomas or capillary malformations with aggravation in the third generation and onset of Parkes-Weber syndrome. Genetic investigation with linkage analysis for the various members in order to identify a predisposing locus yielded little of interest.

Dacarbazine (DTIC) is the first-line chemotherapy for metastatic malignant melanoma without cerebral metastasis. Its clinical and hematological safety is usually good. Hypersensitivity in hepatic failure patients is the most serious side effect described. ⋯ Laboratory monitoring (NFS, liver enzymes) is thus justified, particularly after the first and second courses of DTIC. In case of fever and hypereosinophilia without liver dysfunction, DTIC may be continued together with symptomatic treatment. In the event of hepatic dysfunction, and of course severe hematological disorders, potentially fatal complications can occur and treatment must be stopped.

Capnocytophaga canimorsus is a Gram negative bacillus present in oral flora and in saliva of dogs and cats. It can be responsible for septicaemia and meningitides in some patients after dog or cat bite two patient with a septic shock due to C. canimorsus, who presented with an extensive pupura are reported. ⋯ These severe infections due to C. canimorsus should be avoided by the routine use of early antibiotherapy with amoxicilline and clavulanic acid in patients with dog or cat bite, particularly if patient with associated debilitating disorders.

Dermatologists frequently provide training for general practitioners, but such training is not systematic and evaluation is rare. ⋯ This initial study shows the immediate impact of medical training sessions on general practitioners/occupational physicians to be important in terms of sensitization and moderate but significant in terms of improved diagnosis of pigmented lesions. The longer term impact, as well as the impact of the campaign on physicians not taking part in the medical training sessions, remains unknown. This study militates in favor of the involvement of general practitioners and occupational physicians in mass screening for melanoma in collaboration with dermatologists. The 2004 campaign in the Haut-Rhin Department also included information for the general public. The primary evaluation criterion of the campaign will be change in incidence of thick melanomas recorded by the departmental cancer registry.
