BACKGROUND: Community-onset urinary tract infections (CoUTIs) are the most common bacterial infections, and a decline in antibiotic susceptibility causes many clinical challenges. Adequate empiric antibiotic treatment can decrease unnecessary hospital stays and complications, while reducing the antimicrobial resistance progression. METHODS: From October 2014 to April 2015, we retrospectively enrolled patients who were at least 18 years old and required hospitalization for CoUTIs...

PURPOSE: Radiochromic film for spot-scanning QA provides high spatial resolution and efficiency gains from one-shot irradiation for multiple depths. However, calibration can be a tedious procedure which may limit widespread use. Moreover, since there may be an energy dependence, which manifests as a depth dependence, this may require additional measurements for each patient. We present a one-scan protocol to simplify the procedure. METHODS: We performed the calibration using an EBT3 film at depths of 18, 20, 24cm of Plastic Water exposed by a 6-level step-wedge plan on a Proteus Plus proton system (IBA, Belgium)...

PURPOSE: The use of log files to perform patient specific quality assurance for both protons and IMRT has been established. Here, we extend that approach to a proprietary log file format and compare our results to measurements in phantom. Our goal was to generate a system that would permit gross errors to be found within 3 fractions until direct measurements. This approach could eventually replace direct measurements. METHODS: Spot scanning protons pass through multi-wire ionization chambers which provide information about the charge, location, and size of each delivered spot...

Takae Shimizu, Kazuki Harada
Biofilm formation can cause refractory urinary tract infections (UTIs) in dogs; however, minimum biofilm eradication concentrations (MBECs) of veterinary drugs against canine uropathogens remain to be investigated. In this study, we determined the MBECs of orbifloxacin (OBFX), trimethoprim-sulfamethoxazole (TMS), and amoxicillin/clavulanate (ACV) over different time periods for treatment of canine uropathogenic Escherichia coli (n = 10). We also determined the MBECs of OBFX for other bacterial uropathogens, including Staphylococcus pseudintermedius (n = 5), Pseudomonas aeruginosa (n = 5), Klebsiella pneumoniae (n=5), and Proteus mirabilis (n=5)...

Urinary tract infection (UTI) is a major global infectious disease affecting millions of people annually. Human urinary copper (Cu) content is elevated during UTI caused by uropathogenic E. coli (UPEC). UPEC upregulate the expression of Cu efflux genes during clinical UTI in patients as an adaptive response to host-derived Cu. Whether Cu is mobilized to urine as a host response to UTI and its role in protection against UTI remain unresolved. To address these questions, we tested the hypothesis that Cu is a host effector mobilized to urine during UTI to limit bacterial growth...

REVIEW
Allison N Norsworthy, Melanie M Pearson
Proteus mirabilis is a model organism for urease-producing uropathogens. These diverse bacteria cause infection stones in the urinary tract and form crystalline biofilms on indwelling urinary catheters, frequently leading to polymicrobial infection. Recent work has elucidated how P. mirabilis causes all of these disease states. Particularly exciting is the discovery that this bacterium forms large clusters in the bladder lumen that are sites for stone formation. These clusters, and other steps of infection, require two virulence factors in particular: urease and MR/P fimbriae...

A 46-year-old female patient presented with photosensitivity, symmetric arthritis, episodic plantar pain and strikingly redundant plantar skin folds, likely due to lipoatrophy after recurrent episodes of plantar panniculitis. In this context, leukopenia with lymphopenia, thrombocytopenia and positive antinuclear antibodies were revelatory for systemic lupus erythematosus. However, a small cerebriform plantar collagenoma, along with discrete dysmorphic features with downslanting palpebral fissures and mild right ptosis, second and third syndactyly and a larger first right toe since childhood, and early-onset bilateral ovarian cystadenoma, suggested a minimal Proteus syndrome...

Neonatal meningoencephalitis is a severe condition for the developing brain of a newborn. Radiologic findings of necrosis and liquefaction due to hemorrhagic meningoencephalitis may be confused with brain abcess. In this article, we report a neonate having liquefaction necrosis due to hemorrhagic meningoencephalitis mimicing intracranial abscess due to Proteus mirabilis. We would like to describe the clinical course and evolution of brain imaging and emphasize the importance of the serial MR imaging (MRI).
