Hyperdensity On Head Ct—An Imaging Review, Ramsis Benjamin, Christian Menard, Erik Larson

School of Medicine Publications

The 3D images derived from non-contrast Computed Tomography (NCCT) scans provide a glimpse into the intra- and extracranial structures, based on the ability of electromagnetic X-rays to penetrate through various tissue densities. The gray matter, for example, possesses a higher density than the white matter, absorbs more X-rays, allows less penetration (attenuation), and thus has larger Hounsfield units (HU), the mathematical value of attenuation coefficient. The CT scanner’s wide availability and ease of use allow for quick assessment of acute neurosurgical abnormalities, such as hemorrhages, mass effect, hydrocephalus, and traumatic injuries. An attenuation value of +60 to +90 HU generally …

Mutation of KRAS in endothelial cells (KRAS-EC) leads to intracerebral hemorrhage (ICH) in brain arteriovenous malformations (bAVM), resulting in severe disabilities or even death. However, it is unclear what causes this hemorrhagic conversion of bAVM. Here, using a locally established, clinically-relevant sporadic bAVM mouse model, created by overexpressing mutant KRAS (KRASG12V) in the brain EC, we demonstrate that KRAS-EC act as trigger for microglia (MG) activation and infiltration of macrophages (Mϕ). Using three-dimensional immunostaining approach with cleared human and mouse bAVM tissues, we demonstrate an abundance of MG/Mϕ around the bAVM nidus. The presence of MG/Mϕ are correlated to the …

Department of Radiology Faculty Papers

Postoperative infections remain a major complication after spinal fusion surgery, often caused by biofilm-forming bacteria that resist short-term antibiotic prophylaxis. Vancomycin (VAN) is sometimes delivered locally during surgery; however, levels diminish rapidly, leaving patients vulnerable to late-onset infections. We developed a composite hydrogel integrating perfluorohexane-based emulsions within alginate or fibrin matrices to enable both sustained and ultrasound-triggered VAN release. Water-in-oil-in-water emulsions were prepared using fluorosurfactant-stabilized perfluorohexane as the volatile oil phase, then embedded in hydrogels and exposed to ultrasound (2.5 MHz, 5.5 MPa peak negative pressure) to initiate acoustic droplet vaporization for triggered release. Drug release was quantified spectrophotometrically and …

Faculty, Staff and Students Publications

Objective: Children with neurogenic bladder (NGB) are at increased risk for urinary tract infections (UTIs), but there is a lack of guidelines to assist clinicians in diagnosing and treating these children. Our objective was to describe the presentation and treatment of provider diagnosed UTIs in children with NGB compared to children with vesicoureteral reflux (VUR) and to assess the proportion of children with NGB who met a consortium definition of UTI.

Study design: We included children < 18 years old with either VUR or NGB who were diagnosed in the emergency department with a febrile UTI in our multicenter retrospective cohort study. We extracted and compared UTI symptoms and urinalysis results specific to children with NGB to children with VUR. We measured the proportion of UTI diagnoses concordant with the Urologic Management to Preserve Initial Renal Function (UMPIRE) consensus definition of UTI, defined as ≥ 100,000 CFU/mL of 1 or 2 organisms, pyuria, and ≥ two symptoms of UTI.

Results: The most common symptom among all children in the cohort was vomiting (38.8 %). Of the 215 children with NGB, 41.3 % met …

A Scalable Organoid Model Of Urothelial Aging For Metabolic Interrogation, Infection Modeling, And Reversal Of Age-Associated Changes, Adwaita R Parab, Arnold M Salazar, Steven J Bark, Margarita Divenko, Vasanta Putluri, D'Feau J Lieu, Aadya S Singh, Nagireddy Putluri, Indira U Mysorekar

Faculty, Staff and Students Publications

Aging leads to a progressive decline in overall bladder function resulting in lower urinary tract symptoms and increased susceptibility to infections. However, tissue-specific mechanisms of aging, specifically the contributions of the urothelium, remain elusive. Here, we introduce mouse bladder epithelium-derived organoids (mBEDOs) as a scalable platform to model urothelial aging. mBEDOs from aged mice recapitulate key features of age-associated cellular reprogramming, including oxidative stress, senescence, and DNA damage. We demonstrate the utility of mBEDOs for modeling Uropathogenic Escherichia coli (UPEC) infection, generating assembloids between mBEDOs and macrophages to model epithelial-immune interactions, and genetic perturbation. Using the mBEDO platform, we also …

Partial Versus Full Revision In Cementless Single-Stage Exchange For Hip Periprosthetic Joint Infection: A Multicenter Comparative Study With 10-Year Survivorship Analysis, Wenbo Mu, Atthakorn Jarusriwanna, Boyong Xu, Scot A. Brown, Xiaogang Zhang, Alexander Dawes, Javad Parvizi Md, Li Cao

Rothman Institute Papers

BACKGROUND: Periprosthetic joint infection (PJI) is one of the most challenging complications following total hip arthroplasty (THA). Traditional management typically involves full revision to ensure comprehensive infection eradication. However, for patients with well-fixed implants, partial revision in a single-stage cementless approach may provide a viable alternative, potentially preserving bone stock and reducing operative time. The relative efficacy of this approach compared with full revision remains to be fully explored. This multicenter study aims to determine whether partial revision in cementless single-stage exchange surgery offers comparable infection control outcomes to full revision for select patients with well-fixed implants.

METHODS: We conducted …
