Surgical outcomes of periprosthetic distal femur fractures after total knee arthroplasty classified by Su et al. system.

Background: Periprosthetic fractures of the distal femur remain a challenge to treat due to variations in both patient- and fracture-specific factors. This study was designed to analyze the outcomes of different subtypes of periprosthetic distal femur fractures based on the Su et al. classification system.

Proteus-Like Syndrome: A Rare Phenotype of Phosphatase and Tensin Homolog Hamartoma Tumor Syndrome.

The phosphatase and tensin homolog (PTEN) hamartoma tumor syndrome (PHTS) is a collection of diseases stemming from mutations in the PTEN tumor suppressor gene and is characterized by variable expressivity and abnormal overgrowth in multiple body systems. Its clinical manifestations include, but are not limited to, lipomas, limb overgrowth, dermatologic lesions, and malignancy. The infrequency of occurrence and broadness of clinical presentation has made the diagnosis and differentiation of different subtypes of PHTS challenging.

A Rare Anatomic Variant of Double Replaced Hepatic Arteries: A Case Report and Brief Review of the Anomalous Hepatic Vasculature Literature.

BACKGROUND The liver is a frequent site of surgical resection for both benign and malignant lesions. Advanced knowledge of the hepatic arterial system and its variants is crucial to avoid incidental injuries during a resection procedure. Many variants have been previously described in the literature, yet extremely rare cases continue to be encountered in clinical practice.

Diagnosing cystic duct patency during myocardial perfusion imaging (MPI), using Tc99m Sestamibi (MIBI), as an adjunct benefit in the acute setting.

Objective: Tc99m methoxy isobutyl isonitrile (MIBI) has been used for myocardial perfusion imaging (MPI) for the detection of ischemia. This study aimed to investigate the feasibility of effectively evaluating cystic duct patency, during routine visual analysis of the raw MPI and/or with the three-dimensional reconstructed data.

Methods: A retrospective investigation of 91 patients undergoing cardiac MIBI scan for acute chest pain and hepatobiliary scintigraphy (HBS) was performed, within no more than 3 months for suspected gallbladder obstructive disease.

Construction and validation of UV-C decontamination cabinets for filtering facepiece respirators.

We present evidence-based design principles for three different UV-C based decontamination systems for N95 filtering facepiece respirators (FFRs) within the context of the SARS-CoV-2 outbreak of 2019-2020. The approaches used here were created with consideration for the needs of low- and middle-income countries (LMICs) and other under-resourced facilities. As such, a particular emphasis is placed on providing cost-effective solutions that can be implemented in short order using generally available components and subsystems.

Overreporting of the disc herniation in lumbar spine MRI scans performed for patients with spondylolisthesis.

Background: Spondylolisthesis is often misdiagnosed on magnetic resonance imaging (MRI) as the slip may reduce to a normal alignment when the patient lies supine. Often, disc herniation is reported at the level of spondylolisthesis.

Purpose: To determine the incidence rates of disc herniation at the level of spondylolisthesis.
