[Pseudo-late onset cutaneous parphyria in haemodialysis patients. Clinical and histological features. 9 cases (author's transl)].

In the context of a study of cutaneous problems seen in chronic renal failure patients on intermittent haemodialysis, the authors noted bullous eruptions very similar to late onset cutaneous porphyria. The bullae occur during the summer and are situated on exposed areas, in particular the head and neck. There is skin fragility and the bullae are transient, giving place to erosions and later to atrophic scarring. Even pseudo-miliary cysts have been observed. Histology reveals a sub-epidermal bulla, the basis of which consists of spiky papillary dermis. Immunofluorescence show immunoglobulin deposits in the vessels and basal membrane. All porphyrin measurements are negative. This disorder may be due to the presence of a non-porphyrinogenic photo-sensitising substance, found in certain types of plastic tubing.

[Detection of pseudo-porphyria cutanea tarda in 100 hemodialyzed patients (author's transl)].

In this study, 100 hemodialyzed patients were examined for pseudo-porphyria cutanea tarda, which was first described in 1975. Pseudo-porphyria cutanea tarda was found in 16%. Our main concern was the analysis of the etiological factors; none of the hypotheses so far put forward--a medicinal agent, an hepatic disorder, or some factor relating to the material used in the dialysis--has been confirmed. On the other hand, this condition occurred in patients with the longest interval since dialysis, and who were more often than not completely anuretic. These facts would seem to indicate that this is part of a premature ageing process which is common in these patients.

[Scleroderma en coup de sabre with homolateral chronic glaucoma (author's transl)].

A 37 years old woman presented with scleroderma en coup de sabre of the head with chronic homolateral ocular hypertony. Skin disorders appeared in the childhood and extended slowly until the age of 20. Glaucoma, found 5 years earlier, was unimproved by medical treatment; the opposite eye was normal. Two goniotomia in 1974 were uneffective. A trabeculectomy in 1975 was followed by scleral fistula with important ocular hypotonia. A scleral flap was followed by the disappearance of hypotonia with no return to previous hypertony. The connections between scleroderma and glaucoma are discussed; vascular and neurologic mechanisms are suggested. Up to now, glaucoma has been reported in patients with systemic soleroderma and Romberg disease.

[Clinical and statistical study of 100 patients with vitiligo. II. Associated lesions].

A study of 100 cases of vitiligo showed the frequency of associated skin and visceral lesions. A skin disease was associated in 24 cases: psoriasis 4 cases, alopecia 4 cases, eczema 3 cases, malignant melanoma 2 cases, dermatitis herpetiformis 1 case, lichen planus 9 cases. However, only one case of Sutton's naevus was noted. Among other associations noted in 28 cases, there were 7 cases of thyroid disease, 5 cases of diabetes, 1 case of chronic rheumatoid arthritis and 3 gastric disorders. The frequency of these various associations was discussed in the light of other authors' reports. If one compares the 21 cases associated with auto-immune disease and the other cases of vitiligo, there was no significant difference for the various parameters studied. Thus the significance of the various biological signs of autoimmunisation remains doubtful and even the precise definition of vitiligo remains uncertain.

[Clinical and statistical study of 100 vitiligo patients. I. Etiologic factors and clinical study].

A study of the etiological factors in 100 cases of vitiligo showed female predominance (59%) variable age of onset, absence of radial factor, moderate influence of psychological, physical or endocrine factors, the large number of subjects belonging to group B, a family history in 18% of cases. The morphology site and course of the lesions were also studied. There was no significant correlation between the course of the disease and the various etiological and clinical parameters studied.

[The Waardenburg-Klein syndrome].

A case of Waardenburg-Klein syndrome associated with a Hodgkin's disease is reported in a 29 year old female. Such an association seems to be fortuitous. The authors discuss the dermatological aspects of this rare disease, particularly the disturbances of cutaneous pigmentation. Ultrastructural study of depigmented skin indicates the melanocytes are absent and precise the place of this depigmentation in the group of genetic abnormalities of skin pigmentation.

[Paraneoplastic ichthyosis. Ultrastructural study].

A case of ichthyosis in association with bronchial carcinoma is studied by electron microscopy. Keratohyaline granules are always present in only one layer; variable in size but often reduced upon short tonofilament bundles, they are structurally normal. This suggested a reduced synthesis of a normal keratohyalin, different from the synthesis of an abnormal few spongy keratohyaline in autosomal dominant ichthyosis vulgaris.

[Therapeutic action of coagulation factor XIII in scleroderma. 20 cases].

Clotting factor XIII was used in 13 patients suffering from scleroderma, 17 with generalised scleroderma and 3 with localised scleroderma. The duration of treatment varied between 15 days and 6 months. The effect was marked in 7 cases and more moderate in 5 others. It took the form of increased suppleness of the skin, improved joint mobility and, to a lesser degree, an improvement in vasomotor disturbances of the extremities. Oesophageal abnormalities on X-ray were never altered. The return to normal of alveolar-capillary diffusion seen in two cases requires futher confirmation. The action of factor XIII in scleroderma may be explicable by the formation of transamidation bonds between the alpha chains of the collagen molecule, similar to those obtained on fibrin.
