[Isolated mucosal ulcers disclosing idiopathic hypereosinophilic syndrome]. / Ulcérations muqueuses isolées révélatrices d'un syndrome hyperéosinophilique idiopathique.

INTRODUCTION: Idiopathic hypereosinophilic syndrome is an uncommon disease often associated with diverse non-specific skin manifestations. Mucosal ulcerations suggest a myeloproliferative from with poor prognosis due to possible progression to malignant hemopathy or visceral complications. CASE REPORT: A 28-year-old man presented idiopathic hypereosinophilia with isolated mucosal ulcerations involving the buccal and genital areas. Laboratory results (hematology, CD25) suggested a myeloproliferative form. Treatment with alpha interferon (18 months) led to regression of the mucosal lesions and a decrease in the markers of eosinophil toxicity. There was no visceral involvement. DISCUSSION: Immunosuppression with/without high-dose alpha interferon is usually used for the treatment of hypereosinophilic syndrome. In our case favorable outcome was obtained with lower doses of alpha interferon than those reported in the literature. There was objective decrease in eosinophil toxicity (regular counts of hypodense eosinophils, CD25 or interleukin 2 soluble receptor) and no progression (malignant hemopathy, mortal visceral involvement).

[Cutaneous manifestations of Kawasaki disease. Apropos of 30 cases]. / Manifestations cutanées de la maladie de Kawasaki. A propos de 30 observations.

A series of 30 cases of Kawasaki disease has been studied retrospectively over a period of 11 years. The aim was to reassess the diagnostic value of the dermatological manifestations. A modification of the extremities was observed in 28 patients (23 had early inflammatory lesions, 25 had late desquamation). Exanthema was constant, polymorphous and most often urticaria-like. Vesicles, pustules or purpura were noted during the course of the eruption in 7 patients. A perineal eruption was observed in 17 cases and was found of good diagnostic value even though not pathognomonic. Cheilitis was the most frequent of buccopharyngeal modifications (93 p. 100). Conjunctival hyperemia was noted in 26 patients. Eight children had cardiovascular complications. Among these cases, the modification of the extremities seemed to be more pronounced and stomatitis and arthritis were apparently more frequent. Most of all, the inflammatory syndrome was significantly more severe as concerns CRP and polymorphonuclear leukocytes counts. Dermatological examination often rules out other diagnoses, such as measles, scarlet fever and staphylococcal toxic shock syndrome. However, a complete etiological workup remains mandatory.

[Cardiac involvements in scleroderma: study with echocardiography and cardiac Doppler in 38 patients]. / Atteintes cardiaques au cours des sclérodermies: étude en écho-cardiographie et Doppler cardiaque chez 38 patients.

A study of heart lesions has been conducted in 38 patients with systemic sclerosis using echocardiography, doppler and colour doppler. Abnormalities were found in 66% patients. Valvulopathies (mainly mitral regurgitation) were the most frequent lesions (45%). The presence of anti-SCL70 antibody was correlated to right cavities dilatation. Pulmonary hypertension was found in 6 patients.
