Physician Approaches to the Pharmacologic Treatment of Dystonia in Cerebral Palsy.

Objective: To determine how physicians approach pharmacologic dystonia treatment in people with CP and assess physician readiness to participate in a randomized trial comparing existing pharmacologic dystonia treatments.

Methods: We administered a REDCap survey to physician members of the American Academy of Cerebral Palsy and Developmental Medicine and of the Child Neurology Society to assess which pharmacologic agents they use to treat dystonia in CP and their preferred indications and dosing.

Results: Of 479 physicians surveyed, 240 (50%) responded.

Outpatient Randomized Controlled Trials in the Covid-19 Era and Beyond.

Outpatient Trials in the Covid-19 Era and BeyondA group of investigators had a meeting at the National Heart, Lung, and Blood Institute in May 2020 to discuss ways to decrease thrombotic complications among symptomatic outpatients with Covid-19. The investigators discuss their approach to three specific challenges: conducting a trial remotely, working through regulatory hurdles, and recruiting a diverse population of participants.

Effect of Antithrombotic Therapy on Clinical Outcomes in Outpatients With Clinically Stable Symptomatic COVID-19: The ACTIV-4B Randomized Clinical Trial.

Importance: Acutely ill inpatients with COVID-19 typically receive antithrombotic therapy, although the risks and benefits of this intervention among outpatients with COVID-19 have not been established.

Objective: To assess whether anticoagulant or antiplatelet therapy can safely reduce major adverse cardiopulmonary outcomes among symptomatic but clinically stable outpatients with COVID-19.

Design, Setting, And Participants: The ACTIV-4B Outpatient Thrombosis Prevention Trial was designed as a minimal-contact, adaptive, randomized, double-blind, placebo-controlled trial to compare anticoagulant and antiplatelet therapy among 7000 symptomatic but clinically stable outpatients with COVID-19.

Musculoskeletal Ultrasound as a Motivator for Selecting a Physical Medicine and Rehabilitation Residency Program in the United States: A Multicenter Survey Study.

This study aimed to determine the influence of musculoskeletal ultrasound (MSKUS) curriculum on applicants during the residency-selection process. A survey of 666 applicants for the Johns Hopkins University, Mayo Clinic, and Harvard/Spaulding Rehabilitation Physical Medicine and Rehabilitation programs was conducted in June 2020. A total of 180 respondents scored the influence of a MSKUS curriculum on their decision making for residency selection.

Sonographic evaluation of the extensor carpi ulnaris in asymptomatic tennis players.

Objective: To determine the prevalence of structural abnormalities and instability affecting the extensor carpi ulnaris (ECU) tendons of asymptomatic recreational tennis players by the use of high-resolution ultrasonography.

Design: Cross-sectional observational study.

Setting: Academic sports medicine center.

Distribution pattern of sonographically guided iliopsoas injections: cadaveric investigation using coned beam computed tomography.

Objectives: To investigate the distribution pattern of sonographically guided iliopsoas (IP) injections in an unembalmed cadaveric model.

Methods: A single experienced operator completed 10 sonographically guided IP injections in 5 unembalmed cadaveric pelvic specimens (4 male and 1 female; ages 55-95 years; body mass indices, 15.5-27.

Posttraumatic fat necrosis presenting as prepatellar loose bodies in an adolescent football player.

A 16-year-old high school football player presented with 4 months of anterior knee pain and small, mobile, prepatellar "lumps" after falling onto an opponent's cleat. He reported knee pain primarily during knee flexion and direct pressure during squatting and kneeling. Knee radiographs were unremarkable.

Ultrasound-guided ischial bursa injection: technique and positioning considerations.

Objectives: To 1) describe and validate an ultrasound-guided ischial bursa injection technique in an unembalmed cadaveric model and 2) to compare the distance between the ischial tuberosity and the sciatic nerve in a hip neutral versus 90° flexed hip position in asymptomatic volunteers.

Design: The first part was a single-blind prospective study. The second part was a prospective cohort study.

Sonographically guided obturator internus injections: techniques and validation.

Objectives: The primary purpose of this investigation was to describe and validate sonographically guided techniques for injecting the obturator internus (OI) muscle or bursa using a cadaveric model.

Methods: A single experienced operator completed 10 sonographically guided OI injections in 5 unembalmed cadaveric pelvis specimens (4 female and 1 male, ages 71-89 years with body mass indices of 15.5-24.

Ultrasound-guided intra-articular knee injection in an obese patient.

A 35-yr-old woman was referred to our outpatient clinic for a right intra-articular knee aspiration and injection. She had a medical history notable for lymphedema and morbid obesity (Fig. 1).

Ultrasound-guided versus nonguided tibiotalar joint and sinus tarsi injections: a cadaveric study.

Objective: To compare the relative accuracy rates of ultrasound (US)-guided versus nonguided ankle (tibiotalar) joint and sinus tarsi injections in a cadaveric model.

Design: Prospective human cadaveric study with injection technique randomized and accuracy assessed by skilled observers blinded to injection technique.

Setting: Procedural skills laboratory in a tertiary care academic medical center.

Sonographically guided carpal tunnel injections: the ulnar approach.

Objective: The purpose of this report is to describe a new sonographically guided technique for carpal tunnel injections using an ulnar approach.

Methods: Previously published sonographically guided techniques for carpal tunnel injections were reviewed. Described approaches were noted to be technically challenging because of the need to perform long-axis imaging of the carpal tunnel, short-axis (out-of-plane) imaging of the needle, or both.

Femoroacetabular impingement: an overlooked cause of hip pain.

Femoroacetabular impingement is a cause of hip pain arising from abnormal contact between the proximal femur and the acetabulum during terminal hip motion. This is caused by a structural abnormality at the femoral head/neck junction or the acetabulum. The problem usually presents in young adults and can often go undiagnosed for years.

Intramuscular hemangioma of the foot: a diagnostic dilemma.

Intramuscular hemangioma is a rare but important cause of pain and potentially decreased performance in athletes. These benign tumors occur more often in the lower extremity and usually present during the first three decades of life. Symptomatic intramuscular hemangiomas usually present with pain and swelling, which often worsen with activity.

Cognitive and behavioral correlates of low vitamin B12 levels in elderly patients with progressive dementia.

Vitamin B12 deficiency is common in elderly persons, yet its role in dementia and psychiatric illness is unclear. The authors examined the relationship between vitamin B12 serum levels and cognitive and neuropsychiatric symptoms in dementia. Community-dwelling elderly subjects (N=643) meeting NINCDS-ADRDA criteria for probable or possible Alzheimer disease (AD) underwent comprehensive neuropsychiatric evaluation and measurement of vitamin B12 serum levels.
