[Neonatal lupus].

Neonatal lupus erythematosus is characterized by congenital atrioventricular heart block and/or transient lupus skin lesions frequently similar to those seen in patients with subacute cutaneous lupus erythematosus. The mothers have anti-SSA (Ro) and/or anti-SSB (La) antibodies. The syndrome is important to recognize because newborns may develop complete heart block with congestive heart failure. However, in the majority of cases, neonatal lupus erythematosus is a relatively benign disorder and cutaneous lesions generally disappear completely by 6 months of age.

Poikiloderma of Theresa Kindler: report of a case with ultrastructural study, and review of the literature.

Kindler's syndrome occurred in a 13-year-old boy with parental consanguinity. The patient had acral congenital blistering and photosensitivity, both regressive, at 12 years of age, together with diffuse progressive poikiloderma, marked cutaneous atrophy, mild hyperkeratosis of the palms, gingival hypertrophy and fragility, and anal stenosis. The ultrastructural study of bullae induced by rubbing showed clefts in three levels of the dermoepidermal junction zone. A review of 14 cases in the literature consistent with Kindler's syndrome showed this to be a definite clinical entity among the other bullous hereditary poikilodermas. In two cases, ultrastructural studies showed intraepidermal, junctional, and dermal cleavage. This syndrome must be differentiated from congenital epidermolysis bullosa, Weary's syndrome, and the other bullous hereditary poikilodermas.

Randomised double-blind placebo-controlled trial of local cyclosporin in atopic dermatitis.

The efficacy of local applications of 10% cyclosporin gel was studied in a randomised double-blind placebo-controlled trial in atopic dermatitis. Twenty atopic patients, presenting with stable symmetrical lesions, participated in the study. They applied cyclosporin gel to one side and placebo gel to the other side twice a day. The lesions were assessed on day 0 and day 14 according to lesional criteria scored from 0 to 3. The mean score for each criterion on day 14 was significantly lower on the sides treated with cyclosporin than on the sides treated with placebo. The total mean score on day 14 was 6.1 +/- 3.9 on the sides treated with CSA and 9.6 +/- 3.9 for placebo (p less than 0.005). These findings suggest the efficacy of local CSA applications on lesions of atopic dermatitis.

[Autoimmune polyendocrinopathy and chronic mucocutaneous candidiasis].

The authors report the case of a child who, at the age of 18 months showed signs of hypoparathyroidism together with gastrointestinal, then buccal, then ungual candidiasis. Acute adrenal failure occurred when he was 5 1/2 years' old. At the age of 10, the patient developed alopecia areata and interstitial keratitis. Immunological investigations yielded normal results, except that serum was weakly positive for anti-adrenal antibodies at 1/10th. The mucosal and ungual candidiasis infection was cured by ketoconazole, and the various endocrine abnormalities were corrected with the appropriate replacement therapies. This case prompted the authors to review the candidiasis/"polyglandular autoimmune disease" association. Whitaker's triad consists of candidiasis, hypoparathyroidism and chronic renal failure, 2 or these 3 elements being sufficient to make the diagnosis. Numerous other associations have been described; they are presented here in table form in descending order of frequency, with candidiasis/hypoparathyroidism coming on top of the list (70 p. 100). The fairly constant chronological order in which these different pathologies appear is one of the peculiarities of the syndrome: candidiasis often precedes hypoparathyroidism and adrenal insufficiency. Alopecia areata does not seem to be frequent, but its true incidence is difficult to quantify since lesions of the scalp and/or skin appendages are poorly documented in the literature. Alopecia and keratopathy seem to be of autoimmune origin. Mucocutaneous candidiasis too is specific, the mucosae and nails being constantly involved. This type of candidiasis does not exist in other forms of hypoparathyroidism. Chronic mucocutaneous candidiasis is found in many different diseases and is due to immunodeficiency against Candida spp.(ABSTRACT TRUNCATED AT 250 WORDS)
