Ultrasound imaging was used to investigate vastus medialis architecture in 10 males and 10 females at different knee angles. Increase in muscle thickness occurs predominantly when the knee angle is changed from 0° (full extension) and 45° (p<0.05); increases in VM pennation angle can be predominantly observed between 45° and 90° (p<0.05). Sex differences in the VM architecture can be observed in the distal (p<0.01), but not in the proximal region of the muscle (p>0.11).

Ultrasound has emerged as one of the most utilized tools to diagnose musculoskeletal disorders and to assist in interventions. Traditionally, sonographic examination of the hip joint has been challenging because most of the major structures are deeply situated, thus requiring the use of curvilinear transducer for better penetrance. The posterior lateral hip is a frequent area for musculoskeletal pain and nerve entrapments. Common disorders include greater trochanteric pain syndrome, gluteus medius tendinopathy, piriformis syndrome, pudendal neuralgia and proximal hamstring tendinopathy...

We present a 15-year-old male patient with persistent localized pain on the dorsal side of the left wrist between the base of the 2nd and 3rd metacarpal bones and over the third carpometacarpal joint. It was diagnosed as an accessory metacarpal bone -Os styloideum. This entity may be detected on plain radiographs and in ultrasound examination and is often asymptomatic. Symptomatic os styloideum occurs more frequently in the dominant hand and may be treated conservatively with corticosteroid infiltration. A palpable prominence on the dorsal side of the wrist and focal pain evoked anxiety of the adolescent patient who searched medical consultation...

This is the first study to investigate the usefulness of a standardized ultrasound (US) examination protocol in diagnosing hand osteoarthritis (OA). We conducted a cross-sectional study including 62 patients, ultimately diagnosed with hand OA based on imaging evidence of osteoarthritic changes with the particular distribution required for fulfilment of American College of Radiology diagnosis criteria. We compared a 32-joint US score (wrists, metacarpophalangeal [MCP], proximal interphalangeal [PIP] or distal interphalangeal [DIP] and carpometacarpal [CMC]-1 joints), with smaller, predefined joint scores, assessing 22 joints (wrists, MCPs and PIPs or PIPs, DIPs and CMC-1), 10 joints (MCP 2-3, PIP 2-3 and CMC-1 or PIP 2-3, DIP 2-3 and CMC-1) and 6 joints (DIP 2-3, CMC-1), respectively...

Stretching is often used to increase/maintain joint range of motion (ROM) in children with cerebral palsy (CP) but the effectiveness of these interventions is limited. Therefore, this study aimed to determine the acute changes in muscle-tendon lengthening properties that contribute to increased ROM after a bout of stretching in children with CP. Eleven children with spastic CP (age:12.1(3)y, 5/6 hemiplegia/diplegia, 7/4 GMFCS level I/II) participated in this study. Each child received 3 sets of 5 × 20 s passive, manual static dorsiflexion stretches separated by 30 s rest, and 60 s rest between sets...

Calprotectin (S100A8/A9), a protein expressed in neutrophils and monocytes/macrophages in circulation and inflamed tissue, is associated with measures of disease activity in rheumatoid arthritis (RA) patients both when measured in ethylenediaminetetraacetic acid (EDTA)-plasma and in serum. We wanted to explore if EDTA-plasma or serum should be preferred for calprotectin as a marker of disease activity. Calprotectin was analysed in EDTA-plasma and serum by enzyme-linked immunosorbent assay (ELISA) at baseline in 141 RA patients, starting biologic disease-modifying anti-rheumatic drugs (bDMARDs), and after three months...

We investigated the effects of the initial length of the muscle-tendon unit (MTU) and muscle pre-activation on muscle-tendon interactions during plantarflexion performed at maximal velocity. Ultrasound images of gastrocnemius medialis were obtained on 11 participants in three conditions: 1) active plantarflexion performed at maximal velocity from three increasingly stretched positions (10°, 20° and 30° dorsiflexion), 2) passive plantarflexion induced by a quick release of the ankle joint from the same three positions, and 3) pre-activation, which consisted of a maximal isometric con-traction of the plantarflexors at 10° of dorsiflexion followed by a quick release of ankle joint...

In clinical practice and literature studies, the most common condition associated to streptococcal tonsillitis used to be acute rheumatic fever (ARF). Several publications in the late years report a more frequent and distinctive entity from ARF following β-hemolytic group A streptococcus infection in patients with post-infectious arthritis, that do not fulfill the modified Jones criteria, the so-called post-streptococcal reactive arthritis (PSRA). A distinctive pattern of clinical framing and biological profile in patients with PSRA following streptococcal tonsillitis is described, with a non-migratory, additive, recent onset (7-10 days) arthritis that affects small and large joints as well, with a bimodal peak of incidence at 8-14 and 21-37 years of age, with variate response to non-steroidal anti-inflammatory drugs and has a tendency for recurrence and persistence...
