Turtle-associated salmonellosis due to Salmonella Litchfield in a 57-day-old infant: a case report.

A 57-day-old boy presented with fever, watery diarrhea, and anorexia and was admitted with suspected acute gastroenteritis. His laboratory data suggested low-level inflammation and cholestasis. His stool culture was positive for Salmonella Litchfield. With suspicion of bacterial infection, the patient received intravenous ampicillin for 5 days. On the fifth day after admission, his inflammatory and cholestasis markers normalized, and he was discharged from the hospital in good condition. His family kept five Japanese pond turtles as pets for one year. As Salmonella Litchfield was isolated from a swab sample of the turtle's body. The patient was diagnosed with turtle-associated salmonellosis. In conclusion, families, particularly those with infants, should avoid keeping turtles in their homes. Pet shop owners and public health authorities must provide appropriate information regarding Salmonella in turtles.

Incidence and Relapse Triggers of Childhood Idiopathic Nephrotic Syndrome between 2006 and 2016: A Population-Based Study in Fukushima, Japan.

Childhood idiopathic nephrotic syndrome (NS) is defined by proteinuria and hypoproteinemia. The incidence of childhood idiopathic NS varies with age, race, residential areas, and social conditions. In Japan, its incidence was estimated to be 6.49 cases/100,000 children. Our study aimed to investigate the incidence, characteristics, and rate of relapse of idiopathic NS in Fukushima between 2006 and 2016. Overall, 158 children aged from 6 months to 15 years old (65.8% male) developed idiopathic NS (median age at onset, 5.3 years). The peak age at onset was three years. The average annual incidence of childhood idiopathic NS was 5.16 (range, 3.47-9.26) cases/100,000 children. The highest incidence was in 2011, which was the year of the Great East Japan Earthquake and nuclear power plant accident, and reportedly caused psychological distress in the children at the time. Conversely, the five-year birth cohort showed minor difference from 2008 to 2012. The rate of incidence in males aged < 5 years was thrice greater than in females of the same age and almost the same for males and females aged 11-15 years. Of 507 total relapses in 115 NS children, common triggers of relapses were steroid discontinuation or reduction and infection. The average annual incidence of childhood NS based on the Fukushima population was lower than previously reported in Japan, and the annual incidence has changed over an 11-year period. These changes may be affected by social or environmental factors, including mental stress associated with lifestyle changes after the disaster.

Haloperidol-Induced Dystonia due to Sedation for Upper Gastrointestinal Endoscopy: A Pediatric Case Report.

Dystonia is a movement disorder characterized by sustained muscle tone. Antipsychotic agents sometimes cause acute dystonia that can rapidly worsen within a few hours or days. Because healthy children rarely receive antipsychotic agents, it is unusual to see antipsychotic agent-induced dystonia in pediatric emergency departments. We report a rare case of a 12-year-old healthy boy who presented with acute dystonia after administration of haloperidol for sedation. He was suspected of laryngeal dystonia because stridor and desaturation were present. The symptoms disappeared with the administration of hydroxyzine. Rapid diagnosis was important in this case because laryngeal dystonia is a potential life-threatening complication due to upper airway obstruction. Considering the risk of side effects, doctors who are not accustomed to administering pediatric anesthesia should consult a pediatrician and/or an anesthesiologist prior to administration of anesthetics to pediatric patients.

Epstein-Barr virus-associated hemophagocytic syndrome in a patient with lupus nephritis.

Hemophagocytic syndrome (HPS) is an unusual but severe illness associated with a variety of infections, as well as genetic, malignant tumors, and autoimmune diseases. We report an 11-year-old girl with systemic lupus erythematosus and nephritis who developed HPS associated with Epstein-Barr virus reactivation. In our patient, the onset of reactive HPS might be related to immunosuppressive treatment during the course of lupus nephritis.

[Antimicrobial resistance in Streptococcus pneumoniae and Haemophilus influenzae isolated from nasopharynx in children].

The aims of this study are to investigate the antimicrobial susceptibility of bacteria isolated from children and clarify the risk factors for the carriage of the resistant strains. We examined the minimum inhibitory concentrations (MICs) of antimicrobial agents against 949 strains of Streptococcus pneumoniae (S. pneumoniae) and 791 strains of Haemophilus influenzae (H. influenzae) isolated at our department between September, 2001 and May, 2003. Of those, 226 S. pneumoniae strains and 115 H. influenzae strains were analysed for the resistance genes. Also we retrospectively reviewed the profiles of 1,359 patients with either S. pneumoniae, H. influenzae, or both in nasopharynx. From the view point of MICs, PSSP strains were 185 (19%), PISP strains were 443 (47%), and PRSP strains were 321 (34%) in 949 S. pneumoniae strains, and BLNAS strains were 545 (69%), low-BLNAR strains were 104 (13%), BLNAR strains were 81 (11%), and BLPAR strains were 61 (8%) in 791 H. influenzae strains. The results of gene analysis showed that all resistant strains by MICs such as PISP, PRSP, BLNAR, and BLPAR had resistant genes and that 55% of and 21% of susceptible strains of S. pneumoniae (PSSP) and H. influenzae (BLNAS), respectively, had resistant genes. From the investigation for profiles of 1,359 patients, age less than 3 years old, day nursery, and use of antimicrobial agents in last 3 month, seemed to be the risk factors for carriage of resistant strains. To prevent the resistant bacteria from disseminating we should re-consider how to use the antimicobial agents and nurse the young children.
