There are few reports of Streptococcus pneumoniae as a cause of septic arthritis. The aim of this study was to describe our experience with five documented cases of pneumococcal arthritis over 14 years. ⋯ In our experience, S. pneumoniae should be taken into account as a cause of septic arthritis that mainly affects children younger than 15 months. The hip was the most frequently involved joint. Joint fluid culture was the method providing the best diagnostic yield. A high proportion of strains are not susceptible to penicillin. Early diagnosis and management lead to a good prognosis.

Wilms' tumor occurs in 5-10 % of all cases of nephroblastoma. The metachronous form represents 2-3 % of cases. Most (96.2 %) metachronous tumors appear within the first 5 years of the primary tumor. ⋯ The appearance of a metachronous Wilms' tumor 5 years after that of the primary tumor is rare. When a contralateral tumour develops, chemotherapy must be given until the size of the tumor is reduced in order to preserve renal function and avoid dialysis. In patients with chronic renal failure caused by bilateral nephrectomy, ongoing treatment with dialysis support can be achieved through the choice of effective drugs and knowledge of their pharmacokinetics and pharmacodynamics.

To study the epidemiological changes observed in pediatric poisonings treated in our Emergency Department between 1988 and 1999. ⋯ In the last ten years, visits for possible episodes of pediatric poisoning have decreased, mainly those due to mild poisoning caused by household products. Paracetamol has replaced acetyl-salicylic acid as the most frequently implicated drug.

Congenital myasthenic syndromes are the more frequent group of disorders involving neuromuscular transmission in childhood. They are characterized by hypotonia, weakness and periodic apneic spells, which can be life threatening. Further elucidation of the causes of these syndromes requires sophisticated technology, which is not available in all hospitals. ⋯ Clinical phenotypes and repetitive stimulation can be used to classify the most common myasthenic syndromes and to avoid more aggressive techniques, predict potentially life threatening respiratory exacerbations and avoid iatrogenic effects. They can also be used in genetic counseling.
