Stenotrophomonas maltophilia is a multidrug-resistant, Gramnegative, and biofilm-forming pathogen. Information is limited concerning S. maltophilia bacteremia in children. Clinical data and microbiological test results collected in a tertiary children's hospital over a ten-year period were reviewed. Children 0-18 years old who had positive clinical specimen, blood and/or catheter cultures were included. We identified 20 S. maltophilia isolates from 12 pediatric patients with confirmed infections. The median age was 28 months (range 3.1-187.3). The rate of previous use of antimicrobial therapy was 83 %. The median antibiotic number was 3 (range 0-7) within 30 days prior to onset of S. maltophilia bacteremia. Catheter related infection was the main infectious source (66.6 %). The mortality rate was 33.3 %. The death of two non-survivors was associated with pneumonia. S. maltophilia should be considered a breakthrough agent for bacteremia in children with underlying disease exposed to broad-spectrum antibiotics during long-term hospitalization.Toxocariosis is a parasitic disease caused by the larvae from genus Toxocara sp. There are two classic syndromes described for this entity visceral larva migrans and ocular larva migrans, depending on larvae localization. Human being behaves as an accidental host in which Toxocara sp. does not become an adult worm. This infection is generally asymptomatic but clinical manifestations can be diverse, and they vary according to number and localization of entrenched larvae and host's immune system. In the last years it has been studied a relation between Toxocara sp. and some cutaneous manifestations. We describe the case of a 19-month infant with visceral larva migrans and cutaneous manifestations from vasculitis, explaining its form of presentation, evolution, diagnose and treatment.Beta hemolytic particularly of group A Streptococcus meningitis, is a rare site of the group of invasive infections caused by this microorganism. It occurs frequently in healthy children, without predisposing factors. It represents 0.2-1 % of all meningitis. It is usually installed by dissemination from a nearby focus. The addition of clindamycin improves the treatment efficacy by inhibition of bacterial protein synthesis, including toxin production. The pathogenesis of the disease is not clear, the association with exotoxins was proposed. Co-infection with the influenza virus would favor invasive infections. We present this case of a previously healthy 6-year-old boy with a diagnosis of beta hemolytic Streptococcus meningitis group A, a rare location in children.Streptococcus pneumoniae associated hemolytic uremic syndrome (Sp-HUS) is defined as microangiopathic hemolytic anemia, thrombocytopenia and acute renal injury, in a patient with Streptococcus pneumoniae (Sp) invasive infection. A 2-year-old boy was admitted with pneumonia and empyema. Sp was isolated from blood and pleural fluid cultures. check details After 72 h, the patient showed paleness, asthenia, respiratory whining and oliguria. Laboratory showed anemia, low platelets, increased blood urea, creatirnina, lactate dehdrogenase, direct Coombs +, schistocytes, fibrinogen, normal coagulogram and increased D-dimer. Proteinuria and hematuria were detected in urine. Mechanical ventilatory assistance and transfusions of washed red blood cells were required. The patient recovered progressively. Sp serotype 38 was isolated in the National Reference Laboratory "Malbran". This is the first report associated to this serotype.Osteoporosis should be considered in children with severe chronic diseases or in association with some genetic diseases that bear an increased risk of bone fragility. Primary osteoporosis is an entity in which emerging aetiologies are being recognized. Its association with congenital retinal folds should guide the diagnosis to the Osteoporosis-Pseudoglioma syndrome (OMIM 259770), a rare disease (prevalence of 1/2 000 000), caused by the loss of function of the protein LRP5 (low-density lipoprotein receptor-related protein 5) resulting in the alteration of the Wnt/β-catenin signalling pathway. We report the case of a child with congenital retinal folds, progressive loss of vision and multiple fractures whose clinical, biochemical and genetic studies confirmed the diagnosis of primary osteoporosis due to a novel homozygous inactivating variant in LRP5.The ingestion of more than one magnet can cause multiple complications. Current protocols recommend endoscopic extraction if possible. We report a patient who swallowed two magnets and the endoscopic extraction technique. An 11-yearold boy presented at the Emergency Room after ingesting two small magnets, being asymptomatic. In the abdominal x-ray two radiopaque bodies were identified at the gastric chamber, apparently together. A gastroscopy was done in the operating room under general anaesthesia. To enable the extraction, a neodymium magnet was placed externally at the abdominal wall. In the endoscopic image, the two magnets were fixed to the anterior gastric wall. Once located, the neodymium magnet was removed and the two magnets were retrieved with an endoscopic basket.The entity called tick-borne lymphadenopathy, also known as dermacentor-borne necrosis eritema lymphadenopathy, is included in the differential diagnosis of diseases transmitted by ticks, which have increased considerably in recent years due to greater clinical-epidemiological observation and diagnostic improvement. It is a zoonosis caused by Rickettsia slovaca and transmitted by the bite of the Dermacentor marginatus tick. Affected patients have a necrotic eschar surrounded by an erythematous halo in the scalp, as well as painful regional lymphadenopathy. We present a seven-year-old male who shows, after the extraction of a tick, a necrotic eschar on the scalp, accompanied by lymphadenopathy and low-grade fever. The study of polymerase chain reaction and culture of the lesion confirm the presence of Rickettsia slovaca. The patient received oral azithromycin with a good response. In Primary Care, it is important to monitor the tick bites, to detect possible diseases transmitted by them.
