Uncommon finding in a pulmonary graft versus host disease: A first report of Tsukamurella pneumonia in a pulmonary graft-versus-host disease.

A 64-year-old woman presented to Our Department with 2 weeks history of fever and cough. Through a series of radiological and invasive diagnostic studies we finally reach an unexpected diagnosis of ; Diagnosing an ILD is a dynamic process, and that is the reason why complex cases discussed in a multidisciplinary team may need to be reconsidered in light of evolution of the disease and the results of the performed exams with a flexible approach. is an obligate aerobic, Gram-positive, weakly acid-fast, non-motile bacillus that belongs to the order Pneumonia caused by is exceedingly rare, and only few cases are reported in the literature.

Phenotypic and Genotypic Assays to Evaluate Coagulase-Negative Staphylococci Biofilm Production in Bloodstream Infections.

Coagulase-negative staphylococci (CoNS) are commensal on human body surfaces and, for years, they were not considered a cause of bloodstream infection and were often regarded as contamination. However, the involvement of CoNS in nosocomial infection is increasingly being recognized. The insertion of cannulas and intravascular catheters represents the primary source of CoNS entry into the bloodstream, causing bacteremia and sepsis.

Disseminated Infection in a Child with Complete Interferon-γ Receptor 1 Deficiency due to Compound Heterozygosis of for a Subpolymorphic Copy Number Variation and a Novel Splice-Site Variant.

Complete interferon-γ receptor 1 deficiency is a monogenic primary immunodeficiency caused by germline defects, with autosomal dominant or recessive inheritance, which results in invasive mycobacterial diseases with varying degrees of severity. Most of the autosomal recessive mutations are homozygous loss-of-function single-nucleotide variants, whereas large genomic deletions and compound heterozygosity have been very rarely reported. Herein we describe the clinical presentation, diagnosis, and successful treatment with hematopoietic stem cell transplantation of a child with disseminated infection due to compound heterozygosity for a subpolymorphic copy number variation and a novel splice-site variant.

Migrations do not modify Mycobacterium tuberculosis resistance rates: a 20-year retrospective study.

Tuberculosis (TB) caused by resistant strains is becoming a public health concern also in high-income countries. In Pavia province, Northern Italy, the prevalence of foreign-born has increased in recent years. Nevertheless, it is unclear if this has modified epidemiology and resistance patterns of Mycobacterium tuberculosis.

High Prevalence and Incidence of Diabetic Peripheral Neuropathy in Children and Adolescents With Type 1 Diabetes Mellitus: Results From a Five-Year Prospective Cohort Study.

Background: In this prospective cohort study, we investigated the prevalence of diabetic peripheral neuropathy at baseline and after five years of follow-up in children and adolescents with type 1 diabetes mellitus using both measurements of nerve conduction velocity and clinical neurological examination.

Methods: A total of 38 patients who underwent insulin pump or intensive insulin therapy were included. The subjects averaged 12.

Asaia lannensis bacteremia in a 'needle freak' patient.

The genus Asaia has gained much interest lately owing to constant new species discoveries and its role as a potential opportunistic pathogen to humans. Here we describe a transient bacteremia due to Asaia lannensis in a patient with a psychiatric disorder (compulsive self-injection of different substances). Common phenotypic methods of identification failed to identify this organism, and only restriction fragment lenght polymorphism of PCR-amplified 16S rRNA gene allowed for proper identification.

Evaluation of carbapenem-resistant Enterobacteriaceae in an Italian setting: report from the trench.

The spread of carbapenem resistant Enterobacteriaceae (CRE) has recently become a matter of concern in public health, mainly due to the wide distribution of carbapenemase genes. Italy is a country considered endemic for the spread of blaKPC Klebsiella pneumoniae (KP). The aim of this study was to depict the epidemiological trend of CRE in one Italian hospital over a long period (3 years surveillance, from May 2011 to April 2014).

Late-onset neonatal group B streptococcal disease associated with breast milk transmission: molecular typing using RAPD-PCR.

Group B Streptococcus (GBS) is considered to be the major cause of neonatal sepsis and meningitis of bacterial origin. Late-onset GBS infection is infrequent and occurs between 1 week and 3 months of age. The transmission of GBS through the ingestion of breast milk is reported in the literature, but only a few of these cases have been confirmed by molecular techniques.

Validity of the neurological examination in diagnosing diabetic peripheral neuropathy.

The aim of this study was to evaluate the prevalence of diabetic peripheral neuropathy in children and adolescents with type 1 diabetes mellitus and examine whether the neurological examination validly diagnoses diabetic peripheral neuropathy as compared with the gold standard of nerve conduction velocity in these patients. Nerve conduction velocity was measured in an unselected consecutive series of patients aged 8-18 years who had been suffering from type 1 diabetes mellitus for at least 1 year. For the neurological examination, neuropathy disability scores and neuropathy sign scores were used.

Comparison of the Staphylococcus QuickFISH BC test with the tube coagulase test performed on positive blood cultures for evaluation and application in a clinical routine setting.

Many studies demonstrate that delayed proper therapy in bloodstream infections caused by Staphylococcus aureus increases the mortality rate, emphasizing the need to shorten the turnaround time for positive blood cultures. Different techniques are currently available, from phenotypic methods to more complex tests such as matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF), real-time PCR (RT-PCR), and fluorescence in situ hybridization using peptide nucleic acid probes (PNA FISH). This study evaluated the performance of the Staphylococcus QuickFISH BC test (QFT), a novel FISH methodology, compared with the direct tube coagulase test (DTCT) on blood cultures exhibiting Gram-positive cocci in clusters.

Widespread carbapenem resistant Acinetobacter baumannii clones in Italian hospitals revealed by a multicenter study.

Population diversity, susceptibility to antibiotics including carbapenems of 277 Acinetobacter baumannii strains collected in 17 Italian hospitals over a 6-months' period was assessed. Semi-automated rep-PCR was used for screening strains for genotypic relatedness. AFLP analysis and MLST were used as definitive methods for strain, species and/or clone identification.

Neonatal diabetes mellitus due to pancreas agenesis: a new case report and review of the literature.

Neonatal diabetes mellitus (NDM) is a rare condition (1:400,000 neonates) defined as hyperglycemia occurring in the first months of life, lasting more than 2 wk and requiring insulin for management. We here report on a 33-month-old girl with pancreatic agenesis, an extremely rare cause of permanent neonatal diabetes mellitus (PNDM). Timely diagnosis and adequate treatment of both endocrine and exocrine insufficiency may permit survival and normal development.

Clonal multidrug-resistant Corynebacterium striatum strains, Italy.

We assessed the clinical relevance and performed molecular characterization of 36 multidrug-resistant strains of Corynebacterium striatum. Pulsed-field gel electrophoresis confirmed a single clone, possessing erm(X), tetA/B, cmxA/B, and aphA1 genes, but few related subclones. This strain is emerging as a pathogen in Italy.

Use of the DiversiLab semiautomated repetitive-sequence-based polymerase chain reaction for epidemiologic analysis on Acinetobacter baumannii isolates in different Italian hospitals.

Acinetobacter baumannii is typically a nosocomial pathogen. Epidemiologic tools that can rapidly trace the spread of hospital-associated infections due to this microorganism are essential. Currently, amplified fragment length polymorphism and pulsed-field gel electrophoresis using ApaI, a macrorestriction enzyme, are the molecular techniques most widely used to type this microorganism.

Outbreak of vancomycin-resistant Enterococcus spp. in an Italian general intensive care unit.

Following the identification of two clinical isolates of vancomycin-resistant enterococci (VRE) from intensive care unit (ICU) patients, a surveillance programme detected that six of eight ICU patients were colonised by VRE. Standard epidemic control measures were instituted in the ICU. During a 16-month period, 13 (2.

Identification of coagulase-negative staphylococci other than Staphylococcus epidermidis by automated ribotyping.

As routine identification of coagulase-negative staphylococci is problematic, the performance of automated ribotyping was evaluated for identification of coagulase-negative staphylococci other than Staphylococcus epidermidis. In total, 177 isolates were tested, comprising 149 isolates from blood samples, 15 isolates that were not identified by internal transcribed spacer (ITS)-PCR in a previous study, and 13 reference strains. The identification results were compared with those obtained by the API 20 Staph system, with standard phenotypic and molecular methods as reference.

Extended-spectrum beta-lactamase-producing Enterobacteriaceae in an Italian intensive care unit: clinical and therapeutical remarks.

In this study we evaluated the prevalence of Enterobacteriaceae and the epidemiology of ESBL+ microorganisms in an ICU of our Institution over a 5-year period and analyzed the clinical features and outcomes of the infections caused by these microorganisms. The most frequent ESBL+ isolate was Proteus mirabilis (69 isolates, 58%); a high rate of positive results in the double-disk synergy test (DDS) was also recognized for Klebsiella pneumoniae (52 isolates, 51%), whereas this phenomenon was observed less frequently in other species. In 312 cases the isolated microorganism was considered to be the cause of infection; we documented 103 wound infections, 89 UTIs, 62 LRTIs, 30 primary bacteremias, 27 infections of indwelling catheters and 1 CNS infection.

[Methicillin-resistant Staphylococcus aureus (MRSA) in an intensive care unit: a one-year survey].

Methicillin-resistant Staphylococcus aureus (MRSA) is frequently isolated in nosocomial outbreaks. In our study, we analysed the occurrence of colonisation and infection in an Intensive Care Unit of our hospital during a 12-month period. We also evaluated the possibility of using automated ribotyping as a molecular method in order to type the isolates.
