Prevalence of leukocyturia in a cohort of French asymptomatic aircrews.

OBJECTIVES: Sexually transmitted infections (STIs) can cause leukocyturia. We aimed to estimate the prevalence of leukocyturia in asymptomatic aircrews and the proportion of STIs in those presenting leukocyturia. METHODS: The LEUCO survey was a prospective cohort study conducted among aircrews between 14th October 2019 and 13th March 2020 at the Toulon aeromedical centre in France. All participants performed a dipstick urinalysis. Those positive for leukocyturia were offered STI screening by nucleic acid amplification test (NAAT) for Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium and Trichomonas vaginalis. RESULTS: Among the 2236 included asymptomatic participants (1912 men and 324 women), 127 (36 men and 91 women) were positive for leukocyturia. The prevalence of leukocyturia was 1.9% (1.3-2.6) in men and 28.1% (23.3-33.3) in women (p < 0.001). In men positive for leukocyturia, the NAAT positivity rate for C. trachomatis, N. gonorrhoeae, M. genitalium and T. vaginalis was 28.6% (3.7-71.0) in the age group 18-24, 20.0% (0.5-71.6) in the age group 25-34, and zero in the older age group (p 0.65). In women positive for leukocyturia it was 16.7% (4.7-37.4) in the age group 18-24, 18.2% (2.3-51.8) in the age group 25-34, and zero in the older age group (p 0.16). CONCLUSIONS: In asymptomatic individuals, leukocyturia is rare in men and more common in women. In asymptomatic adults under 35 years of age with leukocyturia, multiplex NAAT shows a high proportion of STIs and might be useful in improving STI detection.

[Dermatitis and arthropods (Anobium punctatum and Cimex lectularius) in summer: three case reports]. / Dermatites et arthropodes (Anobium punctatum et Cimex lectularius) en période estivale : à propos de trois cas.

We report three cases of pruritic dermatitis with erythematous maculopapules, having a similar clinical presentation, in summer, and caused by two different arthropods. In wandering diagnosis since sometimes several months, patients have made entomologic investigations in their home. Two of three samples, have shown an infestation by Anobium punctatum, the common furniture beetle, a xylophagous beetle (usually harmless for human). It may be parasited by Pyemotes ventricosus, a mite known since the 19th century to cause this type of hurt. The third sample contained Cimex lectularius or bedbug, haematophagous insect, classically looked for in endemic zone.

Acinetobacter parvus bacteraemia community-acquired.

Clinicians are generally familiar with Acinetobacter baumannii as an aetiological agent of serious nosocomial infections in intensive care units. Other Acinetobacter species can also be responsible for life-threatening sepsis. Here, we report about a bacteraemia caused by Acinetobacter parvus, community-acquired, identified with a 16S rRNA gene sequence analysis and the MALDI-TOF mass spectrometry system.
