Bone remodeling and cortical thinning distal to the femoral stem: a retrospective review.

Introduction: There is a paucity of information on the bone remodeling that occurs distal to the femoral stem following total hip arthroplasty as most previous studies have focused on proximal changes. In this study, we report the cortical thinning that occur distal to the femoral stem after primary total hip arthroplasty.

Methods: A retrospective review was performed at one institution over a 5-year period.

Frequency of orthopedic manifestations in COVID-19 patients.

Objectives: The effects of the novel coronavirus on the musculoskeletal system have been reported with wide variability. The purpose of this study was to determine the prevalence of musculoskeletal symptoms and if these correlated with other patient characteristics.

Methods: This was a retrospective review of 685 admitted patients who were found to be positive for COVID-19 during their admission.

Factors contributing to anxious driving behavior: the role of stress history and accident severity.

Although fear and travel avoidance among anxious drivers are well documented, relatively little is known about the behavior of anxious individuals who continue to drive. Previous research has identified three broad domains of anxious driving behavior: exaggerated safety/caution behaviors, anxiety-based performance deficits, and hostile/aggressive driving behaviors. In an effort to explicate factors associated with the development of anxious driving behavior, associations with objective accident severity, accident-related distress, and life stress history were explored among individuals reporting accident involvement (N=317).

Familial transitional cell carcinoma of renal pelvis and upper ureter.

A family in which transitional cell carcinoma (TCC) of the renal pelvis and upper ureter developed in three siblings is presented. A description of these patients and their relatives together with a survey of the literature is presented.
