Prediction of Late-Onset Sepsis in Preterm Infants Using Monitoring Signals and Machine Learning.

Objectives: Prediction of late-onset sepsis (onset beyond day 3 of life) in preterm infants, based on multiple patient monitoring signals 24 hours before onset.

Design: Continuous high-resolution electrocardiogram and respiration (chest impedance) data from the monitoring signals were extracted and used to create time-interval features representing heart rate variability, respiration, and body motion. For each infant with a blood culture-proven late-onset sepsis, a Cultures, Resuscitation, and Antibiotics Started Here moment was defined.

Septic arthritis and osteomyelitis in a 10-year-old boy, caused by Fusobacterium nucleatum, diagnosed with PCR/16S ribosomal bacterial DNA amplification.

A 10-year-old boy presented with an atypical non-febrile septic arthritis/osteomyelitis. He was unresponsive to routine antibiotic treatment with flucloxacillin/gentamicin as the pain and fluid collection increased. Synovial fluid cultures are negative and gram stain remained negative.

Method for phenotypic detection of extended-spectrum beta-lactamases in enterobacter species in the routine clinical setting.

In 271 Enterobacter blood culture isolates from 12 hospitals, extended-spectrum beta-lactamase (ESBL) prevalence varied between 0% and 30% per hospital. High prevalence was associated with dissemination, indicating the potential relevance of infection control measures. Screening with cefepime or Vitek 2, followed by a cefepime/cefepime-clavulanate Etest, was an accurate strategy for ESBL detection in Enterobacter isolates (positive predictive value, 100%; negative predictive value, 99%).

Screening for urinary tract infection with the Sysmex UF-1000i urine flow cytometer.

The diagnosis of urinary tract infection (UTI) by urine culture is time-consuming and can produce up to 60 to 80% negative results. Fast screening methods that can reduce the necessity for urine cultures will have a large impact on overall turnaround time and laboratory economics. We have evaluated the detection of bacteria and leukocytes by a new urine analyzer, the UF-1000i, to identify negative urine samples that can be excluded from urine culture.

Group-A-streptococcal meningitis in a 7-year-old child--a rare pathogen in a non-immune compromised patient.

A case is presented of meningitis in a 7-year-old female child caused by Group A streptococcus (GAS), a rare bacterial cause of meningitis, with a high rate of morbidity (46%) and mortality (10%). GAS is susceptible for empiric antibiotic therapy aimed at the most prevalent pathogens of meningitis. As GAS meningitis is typically associated with ear-nose-throat (ENT) infections, specific search for a reservoir is advised.

Recurring staphylococcal scalded skin syndrome in a very low birth weight infant: a case report.

Introduction: Staphylococcal scalded skin syndrome is an extensive desquamative erythematous condition caused by exfoliative toxins of Staphylococcus aureus. This disease usually affects neonates and generally responds rapidly to antibiotic therapy.

Case Presentation: We describe the case of a premature baby boy, weighing 1030 g, born after 26 6/7 weeks gestation, who developed two episodes of Staphylococcal scalded skin syndrome on days 19 and 48 of life.

16S rRNA mutation-mediated tetracycline resistance in Helicobacter pylori.

Most Helicobacter pylori strains are susceptible to tetracycline, an antibiotic commonly used for the eradication of H. pylori. However, an increase in incidence of tetracycline resistance in H.
