BACKGROUND: Alpha defensin is a new biomarker that has been shown to have a very high accuracy to rule out periprosthetic joint infection. Recently, a new rapid lateral flow version of the alpha defensin test was developed and introduced to detect high levels of alpha defensin in synovial fluid quickly and with ease. We conducted a single-center prospective clinical study to compare the results of the Synovasure Alpha Defensin Test with those of the Musculoskeletal Infection Society (MSIS) criteria, which are considered to be the gold standard for diagnosing periprosthetic joint infection...

REVIEW
Vasishta S Tatapudi, Robert A Montgomery
Purpose of Review: Over the past two decades, significant strides made in our understanding of the etiology of antibody-mediated rejection (AMR) in transplantation have put the complement system in the spotlight. Here, we review recent progress made in the field of pharmacologic complement inhibition in clinical transplantation and aim to understand the impact of this therapeutic approach on outcomes in transplant recipients. Recent Findings: Encouraged by the success of agents targeting the complement cascade in disorders of unrestrained complement activation like paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS), investigators are testing the safety and efficacy of pharmacologic complement blockade in mitigating allograft injury in conditions ranging from AMR to recurrent post-transplant aHUS, C3 glomerulopathies and antiphospholipid anti-body syndrome (APS)...

OBJECTIVE: Point-of-care (POC) urine dipstick is a highly used test in the pediatric emergency department (PED) owing to its fast turn-around time and inexpensive cost. Past studies have shown hand-held urine dipsticks and automated urinalysis in children younger than 48 months to be sensitive predictors for urinary tract infection (UTI). It is hypothesized that POC dip testing is as accurate as laboratory urinalysis in the diagnosis of UTI. METHODS: A retrospective chart review was conducted on patients (aged birth through 18 years) presenting to a PED between January 2015 and December 2015...

OBJECTIVES: Screening for urinary tract infection (UTI) includes urinary nitrite testing by dipstick urinalysis. Gram-negative enteric organisms produce urinary nitrite and represent the most common uropathogens. Enterococcus, a less common uropathogen, does not produce nitrite and has a unique antibiotic resistance pattern. Whether to adjust empiric antibiotics in the absence of urinary nitrite has not been established. Our primary objective was to determine prevalence of enterococcal UTI among young children with a nitrite negative urinalysis...

Declan B Keenan, Declan M O'Rourke, Aisling E Courtney
Acute pyelonephritis is suggested by the constellation of fever (temperature ≥ 38.5° C), flank pain (typically unilateral), nausea and vomiting, and costovertebral angle tenderness. Complaints typical of lower UTI are variably present. The severity of symptoms ranges from a mild pyrexial illness to life-threatening sepsis. The diagnosis of acute pyelonephritis should be suspected on the basis of the history and clinical examination. If the urine dipstick is negative for nitrites and leukocyte esterase this does not exclude the diagnosis, but it should prompt a re-evaluation of the clinical features and consideration of other potential diagnoses...

Background: Urinary tract infections (UTIs) are one of the most common bacterial infections in women. During pregnancy physiological changes, like frequency, mimic UTI symptoms, and therefore bacteriological cultures are needed to confirm the diagnosis. However, in developing countries antibiotic therapy is commonly initiated without culture confirmation. Methods: We investigated the prevalence of bacteriuria among pregnant women with and without UTI symptoms in Uganda...

Prosthetic joint infection (PJI) may be underreported because of difficulty in making a diagnosis, especially in infections with low-virulence organisms. Reports of PJI cases misdiagnosed as aseptic loosening suggest that current screening and diagnostic tools are not sensitive enough to detect all infections and that PJI likely is underdiagnosed. We reviewed the literature on recently developed novel synovial biomarkers and polymerase chain reaction (PCR) technologies, of which several have proved promising as highly sensitive and specific tools for detecting PJI...
