[The practice of judo and the risk of fungal contamination].

Over one hundred judokas, a large training tatami, the ground of shower rooms were examined by various methods. Cultures showed that Trichophyton rubrum, though being as frequent as Trichophyton interdigitale on the feet of sportsmen is much less frequent on the training tatami and was never isolated in great quantity from the shower rooms. The problem of fungus contamination in this kind of sportsmen is obvious. Some prophylactic measures are proposed.

Congenital erythropoietic porphyria (Günther's disease): enzymatic studies on two cases of late onset.

Cosynthetase was measured in hemolysates of two patients with CEP that appeared in adulthood. The level of cosynthetase activity was found to be very low (mean 18% of normal), ruling out the hypothesis of heterozygous cases. Several obligatory heterozygous carrier were also studied in whom cosynthetase activity was found to be intermediate (mean 46.66% of normal) between the levels of normal controls and homozygous patients whereas PBG deaminase was always normal. The nature of the metabolic abnormality is undoubtedly a primary defect of the cosynthetase activity; some cases of late onset emphasize the heterogeneity of the disease.

[The histopathology of basal cell carcinomas (author's transl)].

The authors review the different histological forms of basal cell carcinoma, paying particular attention to early forms, sometimes apparently harmless. They stress the diffusing nature of sclerodermiform carcinoma which is often more widespread than clinical appearances suggest. They indicate the current prevalence of basal cell carcinomas in the young individual aged less than 30 years, apparently the consequence of excessive exposure to sunlight. Finally, they give a number of technical indications which are useful in ensuring better orientation and more complete study of the operative specimen, if a frozen section has not been possible, since for this tumour, purely locally malignant, complete excision from the outset offers the best guarantee of cure.

Particular clinical features of psoriasis in infants and chidren.

The onset of psoriasis is observed before the age of 10 years in 15% of all patients. The clinical pattern often takes on a peculiar form. Psoriasis guttata--or less frequently nummular psoriasis--is the initial phase during childhood. It is very difficult to establish a diagnosis on the basis of incipient features when childhood psoriasis is located on the head, palms, soles, or on the fingers, toes and nails. Intertriginous or flexural psoriasis, psoriasis spinulosa and oral psoriasis is also described. The onset of napkin psoriasis starts at the age of 3 months. Occasionally, Leiner's disease may develop into a typical, chronic psoriasis. We have concentrated our studies on the less common features of childhood psoriasis: the generalized pustular infantile form, congenital psoriatic erythroderma, acquired psoriatic erythroderma, and infantile arthropathic psoriasis.

[Lichen striatus with nail involvement. Report of 4 cases and review of the 4 cases in the literature (author's transl)].

Four cases of lichen striatus (L.S.) with nail involvement were studied and the four cases published previously reviewed. There are several types of nail dystrophy: fraying, longitudinal ridging, splitting and shredding, onycholysis, and total nail loss. All of them are transient and can be explained by the pathologic changes observed, particulary the transitory disruption of the basal layer. Lichen striatus must be differentiated from systematized eruptions such as lichen planus (the simultaneous occurrence of L.S. and lichen planus is extremely rare and the resemblance of one dermatosis to the other can be so pronounced that a differential diagnosis is difficult) linear localized neurodermatitis, linear psoriasis (almost always associated with more typical lesions of psoriasis elsewhere on the body), linear keratosis follicularis (histologically typical of Darier's disease) and linear epidermal nevus which occasionaly does not appear at birth but later in life and may present nail involvement. In some cases, however, clinical similarity of the inflammatory linear verrucose epidermal nevus to lichen striatus is striking.
