[Blood pressure monitoring in infants with hemangiomas treated with corticosteroids]. / Surveillance tensionnelle des nourrissons traités par corticothérapie générale pour un hémangiome.

INTRODUCTION: Alarming hemangiomas can be successfully treated with corticosteroids. The risk of hypertension is poorly documented in this setting. We conducted a prospective study in infants with hemangiomas treated with orally administered prednisone. PATIENTS AND METHODS: Thirty-seven patients with rapidly growing complicated hemangiomas were enrolled between January 1998 and November 1999. Steroid dosages varied from 1 mg/kg/d to 5 mg/kg/d. Blood pressure measurements were performed first twice a month, then monthly at rest with a Critikon Dynamap device. Hypertension was defined as blood pressure superior to 110/60 mmHg, and borderline if superior to 110/60 mmHg on only one or two measurements. RESULTS: Increased blood pressure was found in seven infants (19 p. 100). One infant had hypertension requiring specific treatment and blood pressure was borderline on six patients at one or two occasions. Cardiac ultrasound examination was performed in five patients revealing two cases of myocardic hypertrophy, which regressed after stopping steroids and without relationship to hypertension. CONCLUSION: Even though the definition of hypertension in still arbitrary in infants, the measurement of blood pressure is necessary when steroid therapy is given for the treatment of hemangiomas. Blood pressure measurement can be difficult in very young children and overestimation is frequent if an inadequate device is used. The exact place of cardiac ultrasound remains to be defined in the management of alarming hemangiomas.

[Ecthyma gangrenosum caused by Pseudomonas aeruginosa without septicemia in a neutropenic patient]. / Ecthyma gangréneux à Pseudomonas aeruginosa sans septicémie chez une patiente neutropénique.

INTRODUCTION: Ecthyma gangrenosum is a rare skin infection caused by gram negative bacteria. It involves immunocompromised patients, especially neutropenic patients, and can be easily diagnosed. EXEGESIS: We report a case of ecthyma gangrenosum without septicemia due to Pseudomonas aeruginosa in a myelodysplastic patient with severe neutropenia. Granulocyte growth factors adjunction was necessary in combination to antibiotics to obtain complete healing. CONCLUSION: In neutropenic patient, ecthyma gangrenosum due to Pseudomonas aeruginosa should be rapidly diagnosed to avoid septicemic complications. In the case of antibiotic treatment failure, granulocyte growth factors may be added. Frequent Pseudomonas aeruginosa infections justify bacteriologic survey to look for hospital contamination.
