Enteric fever among children: 50 cases in a French tertiary care centre.

Background: Enteric fever in France is primarily travel-associated. Characteristics of paediatric cases are scarce and information from field studies in endemic countries might not be generalizable to non-endemic countries. Methods: In this retrospective study, we reviewed all cases of typhoid and paratyphoid fever treated in a French paediatric tertiary care centre from 1993 through 2015. Results: Fifty cases of enteric fever due to Salmonella enterica serovar Typhi (n = 44) and Paratyphi (n = 6) were identified. Sixty-one percent of the children had travelled to Africa and 34 % to the Indian subcontinent. Among travel-associated cases, eighty-five percent were visiting friends and relatives (VFR). Ninety-six percent had high fever associated with gastrointestinal symptoms. Anaemia (66%), elevated CRP (80%), transaminitis (87%) and mild hyponatremia (50%) were the main biological findings. Blood cultures were positive in 90% of cases. Twelve strains (24%) were resistant at least to one antibiotic, and all of them had been isolated since 2003, increasing the resistance rate during this last period to 43% (12/28). Ceftriaxone was administered to 71 patients for a median duration of 6 days (IQR: 4‒8). The median time to apyrexia after onset of treatment was 4 days (IQR: 2‒5 days). Complications occurred in 9 children with 5 (10%) presenting neurologic disorders. All 50 patients recovered. Conclusion: In France, paediatric enteric fever is mainly a travel-associated disease and occurs in patients returning from a prolonged stay in an endemic area. Children VFR are at high risk and should be a priority target group for pre-travel preventive measures. The increase in antibiotic resistance reflects the situation in endemic countries and is a major concern

Cross-border outbreak of listeriosis caused by cold-smoked salmon, revealed by integrated surveillance and whole genome sequencing (WGS), Denmark and France, 2015 to 2017

International audienceIn August 2017, an outbreak of six listeriosis cases in Denmark was traced to cold-smoked salmon, using epidemiological investigations and whole-genome sequencing (WGS) analyses. Exchange of genome sequences allowed identification in France of a food isolate from a salmon-derived product and a human isolate from 2016 within the same cgMLST cluster as the Danish isolates (L2-SL8-ST8-CT771). The salmon product came from a third European Union country. WGS can rapidly link human cases and food isolates across Europe

Unusual increase in reported cases of Paratyphoid A fever among travellers returning from Cambodia, January to September 2013

From January to September 2013, a marked increase in notifications of Salmonella Paratyphi A infections among travellers returning from Cambodia occurred in France. An investigation revealed 35 cases without a common source: 21 in France, five in Germany, three in the Netherlands, one in Norway, one in the United Kingdom, four in New-Zealand. Data suggest an ongoing event that should trigger further investigation. Travellers to Cambodia should observe preventive measures including good personal hygiene and food handling practices

Treatment and outcomes among patients with Cryptococcus gattii infections in the United States Pacific Northwest.

BACKGROUND: Cryptococcus gattii is a fungal pathogen causing an emerging outbreak in the United States Pacific Northwest (PNW). Treatment guidelines for cryptococcosis are primarily based on data from C. neoformans infections; applicability to PNW C. gattii infection is unknown. We evaluated the relationship between initial antifungal treatment and outcomes for PNW C. gattii patients. METHODS: Cases were defined as culture-confirmed invasive C. gattii infections among residents of Oregon and Washington States during 2004-2011. Clinical data were abstracted from medical records through one year of follow-up. Recommended initial treatment for central nervous system (CNS), bloodstream, and severe pulmonary infections is amphotericin B and 5-flucytosine; for non-severe pulmonary infections, recommended initial treatment is fluconazole. Alternative initial treatment was defined as any other initial antifungal treatment. RESULTS: Seventy patients survived to diagnosis; 50 (71%) received the recommended initial treatment and 20 (29%) received an alternative. Fewer patients with pulmonary infections [21 (64%)] than CNS infections [25 (83%)] received the recommended initial treatment (p = 0.07). Among patients with pulmonary infections, those with severe infections received the recommended initial treatment less often than those with non-severe infections (11% vs. 83%, p<0.0001). Eight patients with severe pulmonary infections received alternative initial treatments; three died. Four patients with non-severe pulmonary infections received alternative initial treatments; two died. There was a trend towards increased three-month mortality among patients receiving alternative vs. recommended initial treatment (30% vs. 14%, p = 0.12), driven primarily by increased mortality among patients with pulmonary disease receiving alternative vs. recommended initial treatment (42% vs. 10%, p = 0.07). CONCLUSIONS: C. gattii patients with pulmonary infections--especially severe infections--may be less likely to receive recommended treatment than those with CNS infections; alternative treatment may be associated with increased mortality. Reasons for receipt of alternative treatment among C. gattii patients in this area should be investigated, and clinician awareness of recommended treatment reinforced

Plant poisoning outbreak in the western area of Cambodia, 2005

An outbreak investigation was conducted during February-March 2005 to determine the cause of several sudden deaths occurring in Pailin Province, Cambodia. Sixty-seven patients presented with non-febrile poisoning-like symptoms and 15 died of coma, including 53% children under 10 years old. Symptoms included sore throat (92%), sore lips (73%), swollen tongue (54%) and gastrointestinal signs (41%). A plant locally called prik was the source of poisoning (97.0 vs. 28.7%, odds ratio 74.3, P<0.001). Patients may have confused the edible Melientha suavis Pierre with Urobotrya siamensis Hiepko, both from the Opiliaceae family. This was the first report of Urobotrya poisoning and its clinical manifestations
