Port-a-Cath Infection of : First Italian Case Report.

is a Non-Tuberculous Mycobacterium (NTM) belonging to the group, often associated with veterinary diseases, such as bovine farcy. However, it can also cause human infections and appears to be involved in Catheter-Associated Infections in immunocompromised patients. Here, we report the first Italian isolation of a strain of from a 16-year-old oncological female patient being treated at Fondazione IRCCS Policlinico San Matteo Pavia (Italy).

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.

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.

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.
