Résumé

OBJECTIVE: To compare the effectiveness and side effects of nebulized l-epinephrine (NLE) at a dose of 0.05 mL/kg versus 0.5 mL/kg in the treatment of postintubation croup in children. MATERIAL AND METHOD: Thirty-nine children, who developed signs and symptoms of upper airway obstruction (UAO) after extubation, were randomized to receive either 0.05 mL/kg or 0.5 mL/kg of NLE. UAO scores, vital signs (VS) and possible side effects were recorded before and at 20 and 40 minutes after the treatment. RESULTS: Twenty-one and 18 patients were allocated to the 0.05 and 0.5 mL/kg groups, respectively. Both groups showed improvements in UAO scores over time. There were no significant differences in UAO scores and VS between the groups at all time points. Side effects of epinephrine were not observed. CONCLUSION: In children with postintubation croup, the administration of NLE at the dose of 0.05 mL/kg results in similar improvements in the UAO scores, compared with the dose of 0.5 mL/kg. No complications were seen in either dose.

Résumé

Systemic vasculitis is a rare complication of therapy with antithyroid medication. Antineutrophilic cytoplasmic antibody (ANCA)-associated vasculitis has been described in patients treated with propylthiouracil (PTU) and methimazole (MMI). The majority of cases have underlying Graves' disease. The authors report 2 children who developed ANCA-associated systemic vasculitis during PTU therapy of Graves' disease. One patient, after PTU treatment for 3 years, developed severe systemic vasculitis. After 3 weeks of arthritis, she abruptly presented with hematuria, proteinuria and edema concomitant with anemia. Her serum creatinine was elevated, to 6 mg/dl. Renal biopsy revealed crescentic glomerulonephritis. After admission, she developed intracerebral hemorrhage and pulmonary hemorrhage. She had positive perinuclear-ANCA (p-ANCA) with a titer of 1:160. Despite intensive therapy with immunosuppressive agents and plasmapheresis, as well as discontinuation of PTU, she died of the complications of severe systemic vasculitis. The other patient developed fever, arthralgia and leukocytoclastic vasculitis of the skin during treatment with PTU for about 2 years. Her symptoms and skin lesions disappeared after discontinuation of PTU. However, she has had a persistently high titer of p-ANCA 1:320 through 17 months follow-up time. Thus, patients who are treated with PTU can develop ANCA-positive vasculitis in a mild or severe form. Therefore, they should be carefully followed and monitored, not only for their thyroid status but also the serious complications of PTU.
