[Acne-like eruption induced by pseudo-xanthoma elasticum (author's transl)].

Pseudoxanthoma elasticum can induce acne-like eruption. The lesions are located on the latero-cervical parts and consist of comedones, cysts and inflammatory nodules. Histologically, there are no transepithelial eliminations or follicultitis, but a very important granulomatosus tissue with epithelioid cells and a giganto-cellular reaction with elastotic fibres phagocytosis.

[Bowen disease of the nail apparatus. Report of 5 cases and review of the 20 cases of the literature (author's transl)].

Five cases of Bowen disease of the nail apparatus were studied and the 20 cases published to date reviewed. The lesion was characterized by either periungual redness with scaling and erosions, whitish cuticle, hyperkeratotic or papilomatous process, fissure or crusted ulcer in the lateral nail fold or the nail bed with eventual partial or total destruction of the nail plate and sometimes soreness on the pressure. The key of the diagnosis is the histological picture, identical with that of Bowen diseases of other skin areas.

[Isotopic angiography. Method of early post-operative control in peripheral vascular surgery. Report of 200 cases (author's transl)].

The authors report their experience of isotopic angiography as means of post-operative control in peripheral vascular surgery in 200 cases. This investigation is very simple and non-traumatic. It gives very satisfactory morphological information and a good idea of the hemodynamics of the acts carried out.

Chequered localized pseudoxanthoma elasticum: a variety of Christensen's exogenous pseudoxanthoma elasticum?

We report a very curious case of a condition which has never been described before. Its features are comparable but not quite identical with those of Christensen's saltpetre-induced PXE which the author considers to be an exogenous variety of pseudoxanthoma elasticum. Since our case appeared spontaneously without any accidental episode we prefer to designate it under the name 'localized PXE'.

[Peritoneal irrigation and lavage using iodinated polyvinyl-pyrrolidone in acute generalized peritonitis (70 cases treated in an intensive care unit)].

The authors report 70 cases of severe acute generalise peritonitis treated during the immediate postoperative periode by peritoneal irrigation-lavage using iodinated polyvinyl-pyrrolidone for 16 days. All of the patients were hospitalised in an intensive care unit because of septicaemia, respiratory distress, acute renal failure, etc. After an aetiological study of these cases of peritonitis, the technique of installation and surveillance and the complications of peritoneal irrigation-lavage are analysed.

Osmotic properties of Ehrlich ascites tumor cells during the cell cycle.

Ehrlich ascites tumor cells were grown and maintained in continuous spinner culture. The population of dividing cells was synchronized by a double thymidine block technique. Cell cycle phases were determined graphically by plotting mitotic index, cell number, and DNA synthesis against time.

[Pilar dysplasies studied in polarized light. An attempt to actualize nomenclature (author's transl)].

The study of congenital hair defects can be made with many methods among which the examination of the hair shaft under polarized light is the most interesting. This scientific, precise and complete method bring the third dimension, allows one to see the slightest structural abnormalities of hair, to make a revision of the classical nomenclature, and should become the routine method for hair examination. We present the principles, the technique and the results.

[End-to-side ileo-colonic anastomosis perpendicular to the band (30 cases) (author's transl)].

Over the last 3 years, the authors restore intestinal continuity after ileo-colonic removal by end-to-side anastomosis according to Bloch's technic the colonic incision is made perpendicular to the peritoneal band. This type of anastomosis, in view of the mode of distribution of the colonic arterioles does not cause any loss of blood supply as is sometimes the case on the antemesocolic border of the incision when it is made on the band. The first results appear very encouraging as in the first thirty cases there was only one case of breakdown of sutures in the anastomosis.

Cockade-like vitiligo and linear vitiligo a variant of fitzpatrick's trichrome vitiligo.

The authors report 2 cases of atypical vitiligo in which they observed 1) "cockade-like" lesions resembling those of "trichrome" vitiligo (from the centre to the periphery, achromic area, hypochromic ring, normal or hyperchromic border), 2) numerous linear achromic lesions corresponding to former excoriations (Koebner's phenomenon, isomorphic phenomenon). Related affections are discussed with reference to these cases; the trichrome vitiligo described by Lerner and Fitzpatrick, and the primary leukomelanodermas described in black patients by Basset and by Sarrat and Nouhouayi.

[Uncombable hair syndrome. Pili trianguli et canaliculi (author's transl)].

We present a general review of a new syndrome that we described in 1973, under the title "cheveux incoiffables" (uncombable half syndrome). The scanning electron microscopy shows two specific alterations of the hair: a triangular section and a longitudinal groove.

[Lamprene (Clofazimine) treatment of chronic lupus erythematoides (author's transl)].

Lamprene (Clofazimine) was administered over a period of three months, at a dose of 100 mg to 200 mg per day, to six patients with chronic lupus erythematosus. Remission was observed in these six cases, without any side-effect.

[Vertical striated sand-papered twenty-nail dystrophy (author's transl)].

Vertical striated sand-papered twenty-nail dystrophy, an entity observed in both children and adults, is suggestive of an expression of alopecia areata. When the vertical striated sand-papered effect is not uniformly distributed over the full surface of the nail plates the disorder may be caused by lichen planus.

[Comel's linear circumflex ichthyosis and Netherton's syndrome. General conceptions based on study of 4 cases (author's transl)].

We have recently observed 4 new particularly demonstrative cases and we think it is adequate to give a general conception in order to bring together in one and a single syndrom the ichthyosis linearis circumflexa Comel and the Netherton's syndrom. We also emphasize some features:--the possible association of ichthyosis linearis circumflexa with family epileptogenous encephalopathy;--a particular type of trichorrhexis which we named "frayed pili torti";--the usual lethality in males, with possible serious viral and pyococcic superinfection;--the characteristics of ichtyosiform erythroderma in the Netherton's syndrom. At the end of this study we confirm that a unicist theory which would consider Netherton's syndrom and ichthyosis linearis circumflexa as one and a single disease should be adopted.
