[COV IMPACT: Stress exposure analysis among hospital staff in 2 hospitals in France during the COVID-19 pandemic].

The COVID-19 pandemic has swept through our hospitals which have had to adapt as a matter of urgency. We are aware that a health crisis of this magnitude is likely to generate mental disorders particularly affecting exposed healthcare workers. Being so brutal and global, this one-of the kind pandemic has been impacting the staff in their professional sphere but also within their private circle.

Reemergence of gentamicin-susceptible strains of methicillin-resistant Staphylococcus aureus in France: a phylogenetic approach.

The reemergence of gentamicin-susceptible (Gen(s)) methicillin-resistant Staphylococcus aureus (MRSA) isolates in France between 1992 and 1996 was investigated using a phylogenetic approach (multiprimer randomly amplified polymorphic DNA typing). Eighty-six percent (65 of 85) of the French strains were grouped into one phylogenetic cluster within which all but one Gen(s) strain were grouped into a subcluster. Thus, the reemergence of Gen(s) MRSA strains in France was likely due to the spread of one specific clone which belonged to a cluster comprising most French gentamicin-resistant (Gen(r)) strains.

[Carcinoma of unknown primary site. Apropos of 100 patients treated at the Montpellier regional center of cancer prevention].

Purpose: Carcinomas of unknown primary site are frequent neoplasms which raise diagnostic and therapeutic problems in clinical practice.

Methods: Clinical records of 100 patients with carcinoma of unknown primary site whose clinical management took place at the Centre Regional de Lutte Contre le Cancer de Montpellier were retrospectively reviewed. Initial clinical and biological characteristics, pre-treatment evaluation, therapies and outcome were recorded.

Molecular epidemiology of ampicillin-resistant non-beta-lactamase-producing Haemophilus influenzae.

Resistance to ampicillin without beta-lactamase production is not a frequent occurrence among Haemophilus influenzae strains. This kind of resistance is encountered in unencapsulated strains isolated from bronchial secretions and ear, nose, and throat specimens and is exceptional in H. influenzae type b.
