BACKGROUND: The origin of jawed vertebrates was marked by profound reconfigurations of the skeleton and muscles of the head and by the acquisition of two sets of paired appendages. Extant cartilaginous fish retained numerous plesiomorphic characters of jawed vertebrates, which include several aspects of their musculature. Therefore, myogenic studies on sharks are essential in yielding clues on the developmental processes involved in the origin of the muscular anatomy. RESULTS: Here we provide a detailed description of the development of specific muscular units integrating the cephalic and appendicular musculature of the shark model, Scyliorhinus canicula...

Gymnotocinclus canoeiro n. sp. of the Hypoptopomatinae is described from small tributaries of the upper rio Tocantins basin. It is distinguished from G. anosteos by having five characters: (1) the presence of body dermal plates, (2) the pectoral girdle not exposed in ventral view, (3) the pelvic spine longer than pectoral spine in males, (4) the pectoral fin with seven to eight branched rays, and (5) the presence of an adipose fin. Furthermore, maximum likelihood (ML) analysis was used to estimate a molecular phylogeny from previously published data of one nuclear (F-Reticulon 4) and three mitochondrial (16S RNA, COI and CytB) genes...

FDG is a tracer for visualizing glucose metabolism. PET/CT using FDG is widely used for the diagnosis of cancer, because glycolysis is elevated in cancer cells. Similarly, active inflammatory tissue also exhibits elevated glucose metabolism because of glycolysis in activated macrophages and proliferating fibroblasts. Elevated FDG uptake by active inflammatory tissues, such as those affected by arthritis, vasculitis, lymphadenitis, and chondritis, has enabled the diagnosis of inflammatory diseases using FDG-PET/CT...

BACKGROUND: The Active Straight Leg Raise is a functional test used in the assessment of pelvic girdle pain, and has shown to have good validity, reliability and responsiveness. The Active Straight Leg Raise is considered to examine the patients' ability to transfer load through the pelvis. It has been hypothesized that patients with pelvic girdle pain lack the ability to stabilize the pelvic girdle, probably due to instability or increased movement of the sacroiliac joint. This study examines the movement of the sacroiliac joints during the Active Straight Leg Raise in patients with pelvic girdle pain...

Valosin Containing Protein (VCP) disease is an autosomal dominant multisystem proteinopathy caused by mutations in the VCP gene, and is primarily associated with progressive muscle weakness, including atrophy of the pelvic and shoulder girdle muscles. Currently, no treatments are available and cardiac and respiratory failures can lead to mortality at an early age. VCP is an AAA ATPase multifunction complex protein and mutations in the VCP gene resulting in disrupted autophagic clearance. Due to the rarity of the disease, the myopathic nature of the disorder, ethical and practical considerations, VCP disease muscle biopsies are difficult to obtain...

Manuel Maia, Diana Costa Santos
BACKGROUND: After massive weight loss, patients typically presented with skin redundancy, which causes enormous esthetic, physical, medical and psychological problems. The growing number of patients with these sequelae triggered an increase in the search for body contouring procedures, which in turn produced an important development in the post-bariatric reconstructive surgery. METHODS: The author describes the principles of a personal approach in post-bariatric reconstructive surgery...

INTRODUCTION: Previous studies show a limited alteration of gait at normal walking speed after spinal fusion surgery for adolescent idiopathic scoliosis (AIS), despite the presumed essential role of spinal mobility during gait. This study analyses how spinal fusion affects gait at more challenging walking speeds. More specifically, we investigated whether thoracic-pelvic rotations are reduced to a larger extent at higher gait speeds and whether compensatory mechanisms above and below the stiffened spine are present...

Most suction-feeding, aquatic vertebrates create suction by rapidly enlarging the oral cavity and pharynx. Forceful enlargement of the pharynx is powered by longitudinal muscles that retract skeletal elements of the hyoid, more caudal branchial arches, and, in many fish, the pectoral girdle. This arrangement was thought to characterize all suction-feeding vertebrates. However, it does not exist in the permanently aquatic, tongueless Pipa pipa, an Amazonian frog that can catch fish. Correlating high-speed (250 and 500 fps) video records with anatomical analysis and functional tests shows that fundamental features of tetrapod body design are altered to allow P...

AIMS: To analyse pain and functional capacity in women with pelvic girdle pain and to evaluate the effect of pelvic belt on these parameters. Two types of belts were to compare. BACKGROUND: Pelvic girdle pain is very common during pregnancy. To prevent and relieve pelvic pain, women can use a set of techniques and tools such as a pelvic belt. While scientific evidence is lacking, commercial industries suggest the effectiveness of pelvic belts. DESIGN: Randomized control trial...

Clear skeletal evidence of prehistoric tuberculosis (TB) is rare, especially in children. We describe and differentially diagnose the pathological changes displayed by a five-year-old child, Pollera 21 (PO21) dated to the Middle Neolithic of Liguria (Italy), or 5740±30 BP (Beta-409341; 6635-6453cal BP, 2σ, OxCal 4.2). PO21 shows a number of osteoarticular lesions, mainly of a lytic nature with very little bone proliferation: the vertebral column, the shoulder and pelvic girdles, and the ribcage are involved...

BACKGROUND: Eolambia caroljonesa is the most abundant dinosaur in the lower Cenomanian Mussentuchit Member of the Cedar Mountain Formation of Utah, and one of the most completely known non-hadrosaurid iguanodontians from North America. In addition to the large holotype and paratype partial skulls, copious remains of skeletally immature individuals, including three bonebeds, have been referred to E. caroljonesa. Nevertheless, aspects of the postcranial anatomy of this taxon, particularly the pelvic girdle, have remained ambiguous due to the lack of associated postcranial material of larger, more mature individuals...

We report the clinical, radiological, biochemical, muscle histology, and electron microscopic features of two members of a family with combined Ehlers-Danlos syndrome (EDS) [classic and vascular type] and progressive myopathy as the primary manifestation. A 35-year old lady presented with severe gluteal and thigh muscle pain and easy fatigability for 5 years. She developed weakness and wasting of pelvic and pectoral girdles and thighs for 3 years and severe neck flexor and truncal weakness for 6 months. She had a history of recurrent jaw dislocation, easy bruising with hyperpigmentation, hyperextensibility of joints, translucent skin, and papyraceous scars...

Musculoskeletal injuries are a common occurrence in military service members. It is believed that the load carried by the service member impedes stability and alters back and pelvis kinematics, increasing their susceptibility to musculoskeletal injuries, specifically in the lower extremities. The purpose of this study was to examine the effects of two different loads on postural sway, forward trunk lean, and pelvic girdle motion in United States Army Cadets. Twenty male Army Reserve Officers' Training Corps Cadets participated in this study...

Variations in musculoskeletal lever systems have formed an important foundation for predictions about the diversity of muscle function and organismal performance. Changes in the structure of lever systems may be coupled with changes in muscle use and give rise to novel muscle functions. The two extant turtle lineages, cryptodires and pleurodires, exhibit differences in hindlimb structure. Cryptodires possess the ancestral musculoskeletal morphology, with most hip muscles originating on the pelvic girdle, which is not fused to the shell...

Antisynthetase syndrome is a heterogeneous idiopathic inflammatory myopathy. Anti-Jo1 is the most common antibody found in this condition. Dermatomyositis is known to be associated with malignancy, but the association between antisynthetase syndrome and malignancy is not clearly established. We report a case of an association of squamous cell carcinoma of the lung and anti-Jo1 antisynthetase syndrome. A 67-year-old man presented with polyarthritis, muscle weakness of the pelvic girdle, "mechanic's hands," and weight loss...

Muscular dystrophies are a heterogeneous group of inherited diseases. The natural history of these disorders along with their management have changed mainly due to a better understanding of their pathophysiology, the evolution of standards of care, and new treatment options. Dystrophinopathies include both Duchenne's and Becker's muscular dystrophies, but in reality they are a spectrum of muscle diseases caused by mutations in the gene that encodes the protein dystrophin. Duchenne's muscular dystrophy is the most common form of inherited muscle disease of childhood...

Polymyalgia rheumatica (PMR) is a rare chronic inflammatory disease. It predominantly affects the elderly. The disease has a slow onset, pain and stiffness in the muscles of the shoulder and pelvic girdle, fever, weight loss, and a high acute-phase inflammatory response. The disease is concurrent with giant cell arteritis in a quarter of cases, which allows some authors to consider them as two different manifestations of the same pathological process. The kidneys are rarely involved. This disease is rarely complicated by AA amyloidosis...
