Molecular picture of community- and healthcare-associated methicillin-resistant Staphylococcus aureus circulating in a teaching hospital in Milan
No full textThe epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) has dramatically changed over the past 10 y with the emergence of community-associated MRSA (CA-MRSA). Recent studies have reported a frequent association of these strains with hospital outbreaks, and an incidence varying over time and by region. In order to evaluate the MRSA lineages circulating in our area of Italy, we performed a molecular characterization of CA-MRSA isolates prospectively collected from April 2006 to July 2007 at the San Paolo Hospital of Milan. We investigated the protein A-encoding gene (spa-typing), the staphylococcal chromosomal cassette SCCmec, the presence of Panton–Valentine leukocidin (PVL), and 3 adhesin genes. Twenty-five CA-MRSA isolates cultured from 25 patients were collected; an equal number of healthcare-associated (HA)-MRSA strains, from 25 patients hospitalized in various wards, were collected for comparison purposes. SCCmec type IV emerged as the most frequent genotype in both CA- and HA-MRSA. Seventeen different spa types were identified: t515 was the most common (36%), followed by t008 (20%). We detected 3 PVL-positive strains, only among the CA-MRSA. On the whole, our local MRSA epidemiology appears to be heterogeneous, with a predominant t515 spa type, only recently considered to belong to clonal EMRSA-15
Prurigo nodularis in a young child with a parasitic infestation with Ascaris lumbricoides
No full textPrurigo nodularis is a chronic dermatosis of uncertain etiology, clinically characterized by itchy nodules occurring on the extensor aspect of the limbs. Here is reported a young Senegalese child with atopic diathesis and asthma, showing superimposed cutaneous lesions compatible with the diagnosis of prurigo nodularis. An intestinal parasitic infestation with Ascaris lumbricoides was also disclosed. Its specific treatment led to a clear improvement of asthma and of the skin lesions
