Rapid screening of COVID-19 patients using white blood cell scattergrams, a study on 381 patients.

Complementary tools are warranted to increase the sensitivity of the initial testing for COVID-19. We identified a specific 'sandglass' aspect on the white blood cell scattergram of COVID-19 patients reflecting the presence of circulating plasmacytoid lymphocytes. Patients were dichotomized as COVID-19-positive or -negative based on reverse transcriptase polymerase chain reaction (RT-PCR) and chest computed tomography (CT) scan results.

[Aging and HIV infection: 4 years follow-up of 149 HIV infected patients older than 60 years in West Paris agglomeration (COREVIH Île-de-France Ouest)].

Unlabelled: In France, patients over 50 years represent more than 23.6% of all registered cases in the French Hospital Database for HIV (FHDH), and 18% of newly HIV-diagnosed patients.

Objective: To describe the long-term evolution after 4 years of a cohort of HIV infected patients older than 60 years recruited in COREVIH Île-de-France Ouest.

Adult-onset Still's disease revealed by perimyocarditis and a concomitant reactivation of an EBV infection.

We describe a 17-year-old patient presenting perimyocarditis as the initial manifestation of the adult-onset Still's disease. Corticotherapy was rapidly successful but induced major acute hepatitis in relation with Epstein-Barr virus reactivation. After 1 year, even if the global outcome is favourable, a slightly lowered ejection fraction still persists.

Concomitant axillary mycobacteriosis and neuro-sarcoidosis: diagnostic pitfalls.

There are many similarities between mycobacteriosis, in particular, tuberculosis, and sarcoidosis such as predominant intrathoracic localisation (even if all organs and tissues may be concerned), great variability of phenotypic expression, and granulomatous inflammatory reaction, caseous necrosis not being an absolute criterion of tuberculosis. Moreover, microbial (or mycobacterial?) agents may play a role in the pathogenesis of sarcoidosis which remains a diagnosis of exclusion particularly in atypical cases. The authors report a case of a non-immunocompromised female patient who presented, simultaneously, isolated axillary tubercular adenitis and neuro-sarcoidosis without any other localisation.

Primary peritonitis due to Streptococcus pyogenes with reduced susceptibility to fluoroquinolones.

We report the 1st case of primary peritonitis caused by Streptococcus pyogenes with a reduced susceptibility to fluoroquinolones in a healthy woman, leading to a clinical and microbiological treatment failure. DNA sequencing of parC and gyrA revealed the association of the following 3 substitutions in ParC: Ser80Pro, Asp91Asn, and Ser140Pro.
