Rat bite fever caused by Streptobacillus moniliformis in a child: human infection and rat carriage diagnosed by PCR.

A child owning pet rats developed an eruptive fever with blisters, polyarthritis, and spectacular desquamation of the hands. Streptobacillus moniliformis was identified after culture of the child's blister fluid and was detected in rat samples by molecular methods. Such detection in the pet of a human victim of rat bite fever has not been reported previously.

[Treatment of exacerbation of asthma: what are today's issues?]. / Traitement de la crise d'asthme: où sont aujourd'hui les enjeux?

During past decades, major progress has been accomplished in the management of acute asthma. Most recent recommendations include evidence-based rationale. The improved quality of clinical guidelines makes them efficient models for medical education. The pediatric pharmacopoeia provides a great variety of choices of drugs as well as for asthma medical devices. These innovations dramatically facilitated the medical management of asthmatic children, but they did not solve all problems. Physicians now use higher doses of salbutamol, but the early prescription of systemic glucocorticoids for moderate exacerbation of asthma is still underused, given the most recent clinical guidelines and meta-analysis. Furthermore, repeated emergency department visits to the wards and lack of primary care physician should systematically be appraised when evaluating severity, as they are both major risk factors for severe exacerbations, even though they are not considered in acute asthma severity scores. Finally, initiating (or reinforcing) patient education at the time of exacerbation also presents important challenges, as emergency visits are a favorable moment to commence the therapeutic education of the child and his family. Indeed, framing the controller medications and educating families about how to manage the disease and to improve their domestic environment are the genuine tools available for the prevention of asthma exacerbations, and particularly those most severe.

[Tetraparesis in an infant after prolonged administration of pancuronium]. / Tétraparésie chez un nourrisson après administration prolongée de pancuronium.

Long-term administration of pancuronium for ventilatory support of adults with ARDS may result in severe tetraparesis, with areflexia and atrophy of distal muscles. This adverse effect occurs rarely in paediatric intensive care units. We describe a case of tetraparesis after prolonged pancuronium infusion in a 9-month-old girl who experienced a severe bronchopneumonia caused by para-influenza virus, requiring endotracheal intubation and mechanical ventilation. To decrease chest wall rigidity, pancuronium was administered over 11 days, with a total dose of approximately 120 mg of pancuronium bromide. The day after discontinuation of the muscle relaxant she had a severe tetraplegia with areflexia, but normal head movements. Electromyography showed a normal neuromuscular transmission. She recovered from tetraplegia three months later. Other causes of peripheral neuropathy were eliminated. Electroencephalograms and head CT-scans were normal. The recovery pattern observed in our patient corresponded to the process of regeneration seen after axonal degeneration. It is suggested that these neuromuscular complications were caused by prolonged high-dosage pancuronium treatment, associated with corticosteroid and aminoglycoside administration.

[Membranous glomerulonephritis in children: 20 cases]. / Glomérulonéphrites extramembraneuses chez l'enfant: 20 observations.

Twenty cases of membranous glomerulonephritis have been diagnosed between 1978 and 1988 in children (13 girls, 7 boys) aged 4 to 15 years, observed for a 5.1 +/- 2.9 year period. The conditions of the diagnosis were: routine urinalysis in 10 cases, edema in eight, and the surveyance of a D-penicillamine treatment in two. All the patients had proteinuria (0.3 to 15 g/24 h) ranging to nephrotic syndrome in nine children. Microscopic hematuria was found in 16 children (80%). Elevated blood pressure was recorded in two cases at the time of diagnosis, and developed in two other cases during the follow-up. One child experienced renal failure at the onset of the disease. Most histological lesions consisted in stage II membranous glomerulonephritis. Immunofluorescence study (18 biopsies/20) always showed granulosus and intensive IgC deposits, associated with IgM and IgA deposits which were less marked; intensive extra-membranous C3 deposits were noted in 11 cases. As to the etiology, D-penicillamine was responsible for two cases (10%) and HBs antigen in one (5%); the nephropathy was considered as idiopathic in the 17 remaining cases (85%). Regarding the evolution: in eight cases (38%) proteinuria disappeared by 54 +/- 28 months; in 10 cases (55%), proteinuria persisted after 41 +/- 31 months; hematuria, which was present at onset, disappeared in most cases (13/17); in one case (5%), end-stage renal failure occurred within 3 years. The patient with initial renal failure has been last sight off.(ABSTRACT TRUNCATED AT 250 WORDS)
