Intramuscular cryptococcosis is extremely rare. In this case, a 76-year-old man with history of acute myeloid leukemia presented a painful mass in the right upper arm. FDG PET/CT demonstrated a low-density irregular-shaped mass in the triceps muscle of the right upper arm with adjacent bone erosion. The lesion presented with significantly increased activity with an SUVmax of 23.4, which could be misdiagnosed as a malignant tumor. The lesion was confirmed as cryptococcosis by periodic acid-Schiff stain and culture of biopsied specimen...

We used eight fresh cadaveric elbows to evaluate the biomechanical characteristics of the native radial head, an anatomic radial head prosthesis, and a non-anatomic radial head prosthesis using a dynamic model. The biceps, brachialis, and triceps were attached to pneumatic actuators loaded to mimic muscle force. The radiocapitellar contact pressure and area were measured in real time, and the associated curves were depicted simultaneously. No significant differences in the contact area or associated curves were found between native radial head and the anatomic radial head prosthesis...

Introduction: With the increasing number of children and adolescents participating in sports, pathologies once reserved for high-level athletes are now emerging in this younger population. Distal triceps tendon tears represent an injury infrequently seen even among older, skeletally mature athletes. We report a case of distal triceps tendon tear with concomitant ulnar collateral ligament (UCL) injury in a skeletally-immature football player. Case Report: This is a rare case of traumatic triceps tendon tear with UCL injury in a 13-year-old male football player during a fall and hyperextension of his elbow...

A variety of musculoskeletal models are applied in different modelling environments for estimating muscle forces during gait. Influence of different modelling assumptions and approaches on model outputs are still not fully understood, while direct comparisons of standard approaches have been rarely undertaken. This study seeks to compare joint kinematics, joint kinetics and estimated muscle forces of two standard approaches offered in two different modelling environments (AnyBody, OpenSim). It is hypothesised that distinctive differences exist for individual muscles, while summing up synergists show general agreement...

OBJECTIVE: To characterize the association of longitudinal changes in maternal anthropometric measures with neonatal anthropometry and to assess to what extent late-gestational changes in maternal anthropometry are associated with neonatal body composition. DESIGN: In a prospective cohort of pregnant women, maternal anthropometry was measured at six study visits across pregnancy and after birth, neonates were measured and fat and lean mass calculated. We estimated maternal anthropometric trajectories and separately assessed rate of change in the second (15-28 weeks) and third trimester (28-39 weeks) in relation to neonatal anthropometry...

The human triceps surae (two gastrocnemii and soleus) has aponeuroses in the proximal and distal aspects, the latter of which insert into the calcaneus by sharing the common Achilles tendon. These tendinous tissues are known to have elasticity and upon muscle contraction the aponeurosis is stretched both longitudinally (along the muscle's line of action) and transversely. Higher aponeurosis transverse deformability has been documented, but there is a paucity of information on the morphology and mechanical properties of human aponeurosis...

INTRODUCTION: In response to fatigue during an exhaustive treadmill run, forefoot runner's muscles must adapt to maintain their pace. From a neuromuscular control perspective, certain muscles may not be able to sustain the force to meet the run's demands; thus, there may be alternative muscle coordination in the lower extremity that allows for continued running for an extended period of time. The aim of this study was to quantify the change in muscle coordination during a prolonged run in forefoot runners...

Cerebral palsy (CP) patients with spastic diplegia struggle to perform activities of daily life (ADL) using their upper arms. The single-joint-type Hybrid Assistive limb (HAL) for upper limbs is a new portable robot that can provide elbow motion support in accordance with bioelectric activation of patient's biceps and triceps brachii muscles. The purpose of this study is to assess the feasibility and efficacy of the use of HAL for CP patients. Two patients were enrolled in this study. (Case 1: a 19-years-old male, at the Gross Motor Function Classification System (GMFCS) level IV, Case 2: a 17-years-old male at GMFCS level III)...

The annular ligament has a crucial role in the radial head stability and  it is critical to the proper functioning of the proximal  radio-capitellar joint. Its chronic injury may lead to radial head instability, elbow pain with decrease in motion and valgus deformity. Method: We present the case of a 53-year-old heavy laborer who reported a complex trauma of the right upper limb with a Floating Elbow Injury, associated to an open Monteggia fracture-dislocation. One month later, despite the definitive fixation with plates of  both the forearm and the supracondylar fractures, X-rays showed the persistence of the radial head dislocation...

OBJECTIVE: Better nutritional reserves are proposed as a mechanism for the protective role of obesity in hemodialysis. Little is known about the quality of diet as a major contributor to nutritional status, specifically body mass index and obesity. The aim of this study was to assess dietary inflammatory index (DII®) score and other parameters of diet in normal-weight and obese patients undergoing hemodialysis to understand whether there is a benefit for obese patients. METHODS: This cross-sectional study included 85 hemodialysis patients (44 obese and 41 normal-weight)...

The triceps surae muscle-tendon units are important in governing walking performance, acting to regulate mechanical behavior of the ankle through interaction between active muscle and passive elastic structures. Ankle joint quasi-stiffness (the slope of the relation between ankle moment and ankle rotation, kA), is a useful aggregate measure of this mechanical behavior. However, the role of muscle activation and length-tension behavior in augmenting kA remains unclear. Here, 10 subjects completed eccentric isokinetic contractions at rest and at two soleus activation levels (25% and 75% isometric voluntary contraction - IVC) prescribed using electromyographic biofeedback...
