[Cutaneous manifestation of pheochromocytoma. Report of a case (author's transl)].

A 33 years old woman was investigated for paroxystic hypertension worsened by bêta-adrenergic blocking drugs therapy. Clinical investigation revealed cutaneous abnormalities with erythemato-macular eruption on dorsalis faces of both hands. These lesions were histologically non specific with capillaritis and oedema.

[9 new Salmonella serotypes isolated in Africa and the Antilles].

Description of nine new serotypes of Salmonella, three isolated in Senegal: S. tambacounda (I,3,I9:b:e,n,x) from Chiroptera, S. bargny (8,20:i:I,5) and S.

[Hereditary porphyria cutanea in children. Enzymatic studies (author's transl)].

A girl of 7 years presenting porphyria cutanea tarda was found to have a very low level of erythrocytary uroporphyrinogen decarboxylase. Tests on her brother, parents and maternal grand-parents, who were all free of the disease revealed the same level of enzyme in the mother and grandmother, through whom the hereditary factor was obviously transmitted. This supports evidence provided by juvenile cases and familial forms in the literature that heredity plays an important part in a disease which is often considered to be acquired or symptomatic.

Unscheduled DNA synthesis in psoriatic skin after ultraviolet irradiation and the effects of a combined treatment with 8-methoxypsoralen and longwave ultraviolet radiation: a clinical study.

Biopsies were taken from psoriatic patients undergoing photochemotherapy and then studied by autoradiography to investigate possible unscheduled DNA synthesis (UDS) following 8-MOP photodamage in epidermal cels. No sparse labelling was found in seventy samples taken from twenty-four different patients during PUVA therapy, indicating a lack of UDS. In contrast, UDS was observed in three patients irradiated with an all-spectrum UV lamp, as a test for DNA damage and excision repair activity.

[Acute generalized exanthematic pustuloses (four cases) (author's transl)].

Acute generalized exanthematic pustuloses supervening without a genetic psoriatic predisposition are not exceptional if the literature over the last few years is taken into account. Such observations are published under a wide range of names. Beside exanthematic pustular psoriasis as defined by Baker and Ryan, there exists in fact a whole scale of amicrobial pustulosis: acute generalized pustular bacterid; acute generalized pustulosis manifestation of leukocytoclastic vasculitis; pustular necroziting angeitis; pustular eruption with eosinophilic abscesses; generalized pustular drug rash; subcorneal pustules in erythema multiforme and in Sweet's syndrome.

[Degos' malignant atrophic papulosis. Ultrastructural study of a new case].

The authors report a case of Degos' malignant atrophic papulosis (MAP) with typical skin lesions from a clinical and histological standpoint. They stress in particular the ultrastructural study of skin biopsies which revealed numerous "paramyxovirus-like" tubulo-reticular structures in the endothelial cells, lymphocytes of the perivascular infiltrate, fibroblasts and keratinocytes. Although the significance of these inclusions remains open to discussion and is probably non-specific, their frequency in MAP is worthy of emphasis.

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.

[Alopecia areata and trisomy 21. About 2 cases (author's transl)].

Two cases of alopecia areata coexisting with trisomy 21 are reported. In the first case, the two diseases were associated with Hashimoto's thyroiditis and in the second, with vitiligo. Pathogenic implications are discussed.
