[Erythema nodosum: etiological changes in the last two decades].

OBJECTIVE: To study the etiological factors associated with erythema nodosum in children hospitalized between January 1985 and December 2003. MATERIAL AND METHODS: We performed a retrospective, descriptive study through review of the medical records of children with a diagnosis of erythema nodosum (MBDS-ICD 9-CM, code 6952). Forty-five patients (27 boys and 18 girls) aged between 10 months and 14 years were studied. The following variables were analyzed: age, sex, associated symptoms, complementary investigations (blood count, erythrocyte sedimentation rate, throat swab, chest x-ray, Mantoux test, ASLO titer, stool culture, serology) and final diagnosis. RESULTS: The most frequent etiology was tuberculosis (10 patients), followed by Salmonella enteritidis (7 patients), group A beta -hemolytic Streptococcus (3 patients), Salmonella typhimurium (2 patients), Campylobacter jejuni (2 patients), Yersinia enterocolitica (1 patient), infectious mononucleosis caused by Epstein Barr virus (1 patient), cat scratch disease (1 patient), BCG vaccination (1 patient), associated chronic hepatitis B infection (1 patient), and associated amoxicillin treatment (1 patient). Etiology was unknown in 15 patients. The last case of erythema nodosum associated with tuberculous infection dated back to 1991, after which the most frequent etiologic factors associated with erythema nodosum were gastrointestinal pathogens. CONCLUSIONS: According to our results, the main etiological factor currently associated with erythema nodosum is gastrointestinal infection. Consequently, stool cultures, especially when there are associated gastrointestinal symptoms, are essential.

[Idiopathic purpura fulminans with transient protein S deficiency].

Idiopathic purpura fulminans produces rapidly progressive hemorrhagic necrosis of the skin with disseminated intravascular coagulation in individuals without known abnormalities of the protein C pathway or acute infections. The disease mainly affects children and in 90 % of cases is preceded by a benign infection. Its pathogenesis involves a temporary autoimmune protein S deficiency that provokes a state of hypercoagulability. We present the case of a previously healthy 2-year-old boy with hemorrhagic skin lesions characteristic of purpura fulminans and disseminated intravascular coagulation without sepsis. Severe, temporary protein S deficiency was confirmed. The patient received daily replacement therapy with fresh frozen plasma for 12 days and anticoagulation with heparin for 3 months. Evolution was favorable. Although the other parameters returned to normal, protein S remained low for 50 days despite treatment. The patient has made a complete recovery.

[Prospective study of newborn infants born to mothers infected with human immunodeficiency virus].

Perinatal transmission of Human immunodeficiency virus (HIV) from mother to child is at the present time the most important cause of AIDS in children. Since August 1985 we have observed 24 babies with anti-HIV antibodies born to HIV-infected mothers. Their present status is: 6 have symptomatic infection, 6 undetermined infection, 10 had became seronegative and 2 were lost for follow-up. Our results suggest that the risk of infection for the baby is high and the onset of symptoms relatively early. Follow-up studies in babies born to HIV-infected mothers are needed in order to classify the true risk of infection in them and the natural history of the disease.
