Severe Scabies: A French Multi-centre Study Involving 95 Patients with Crusted and Profuse Disease and Review of the Literature.

The aim of this multi-centre French retrospective study was to identify severe, i.e. crusted and profuse, scabies patients. Records were retrieved from 22 Dermatology or Infectious Diseases departments in the Ile-de-France from January 2009 to January 2015 to characterize epidemiology, demography, diagnosis, contributing factors, treatment features, and outcomes in severe scabies. A total of 95 inpatients (57 crusted and 38 profuse) were included. A higher number of cases was observed among elderly patients (>75 years), mostly living in institutions. Thirteen patients (13.6%) reported a history of previously treated scabies. Sixty-three patients (66.3%) had been seen by a previous practitioner for the current episode (up to 8 previous visits). Initial misdiagnosis (e.g. eczema, prurigo, drug-related eruptions, psoriasis) was documented in 41 patients (43.1%). Fifty-eight patients (61%) had already received 1 or more previous treatments for their current episode. Forty percent received corticosteroids or acitretin for an initial diagnosis of eczema or psoriasis. Median time from the onset of symptoms to the diagnosis of severe scabies was 3 months (range 0.3-22). Itch was present in all patients at diagnosis. Most patients (n=84, 88.4%) had comorbidities. Diagnostic and therapeutic approaches varied. Complications occurred in 11.5% of cases. To date, there is no consensus for diagnosis and treatment, and future standardization of is required for optimal management.

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. Sensitivity and specificity of the 'sandglass' aspect were 85·9% and 83·5% respectively. The positive predictive value was 94·3%. Our findings provide a non-invasive and simple tool to quickly categorize symptomatic patients as either COVID-19-probable or -improbable especially when RT-PCR and/or chest CT are not rapidly available.

[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)]. / Vieillissement et infection par le VIH: suivi de 149 patients âgés de plus de 60ans infectés par le VIH (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. RESULTS: One hundred and forty-nine participants, 115 men (77%) and 34 women (23%), were included in the cohort analysis in 2004, and baseline characteristics were: median age 65.4 years (60.3-86.3), CDC stage C: 36%, HBV and HCV co-infections: four (2.7%) and eight (5.4%) patients, median time from first HIV infection diagnosis: 8.5 years (0.25-19.5), ongoing HAART regimen: 88%, median duration of ARV treatment: 7.5 years (0.2-15.5), baseline CD4 cells count: 372/mm(3) (18-1860), HIV viral load less than 200 c/ml: 104 (70%). After a 4-year follow-up, 111 patients were alive, all but one treated with HAART, 17/149 (11.5%) were lost for follow-up, and 21/149 were deceased (14%). Causes of death were acute cardiovascular disease (4/21), neoplasia (11/21), neurological disease 1/21, end stage liver disease 3/21, unknown 2/21. The prevalence of co-morbidities after 4 years of follow-up were: arterial hypertension 40/111 (36%), hypercholesterolemia 48/111 (43%), diabetes 23/111 (21%), kidney disease with renal insufficiency (creatinine clairance<60 ml/min): 36/111 (32%). At the end of follow-up, median CD4 cells count was 494/mm(3), and viral load was undetectable less than 200 c/ml in 107/111 patients (96%). No new opportunistic infection occurred during the 4-year follow-up, but 24 patients had a new diagnosis of neoplasia (incidence 40/1000 person-year). Cancer was the cause of death in 11/24. CONCLUSION: Clinical and immunological improvement was continuous under HAART in these aged HIV infected patients, but co-morbidities are frequently observed in this population, with high incidence of cardiovascular disease and neoplasia, and related mortality. A multidisciplinary approach, with preventive consultations, oncology and cardiovascular screening, as done in geriatrics, is warranted in the aging HIV population.

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. Former case reports and differential diagnosis with reactive haemophagocytic syndrome would be discussed.

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. This case illustrates the difficulty to distinguish between both of these two diseases and thus to choose an adequate treatment when diagnosis is not proven. Moreover, our patient (human leucocyte antigen B27 positive) presented symptoms of spondylarthritis which also may have a nosological link with tuberculosis or sarcoidosis.

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.
