One-third of community-dwelling people older than 65 years of age fall each year, and half of them fall at least twice a year. Older care home residents are approximately three times more likely to fall when compared to community-dwelling older people. Risk indicators for falls are related to the older people's body, environment, behavior, and activities. An important health risk indicator is (orthostatic or postprandial) hypotension, which may induce cerebral hypoperfusion. Although the majority of falls remain without major consequences, 10% to 25% of falls in care homes result in bodily trauma...

Fracture of the first rib with ensuing callus formation is a rare cause of thoracic outlet syndrome. We report a case of a 17-year-old female volleyball player who presented with months of chronic arm pain. Radiographic imaging demonstrated nonunion fracture of the first rib. Physical therapy had been unsuccessful in relieving the pain, and surgical management was performed with resection of the first rib through a transaxillary approach with complete resolution of symptoms. Inflammation surrounding such fractures may destroy tissue planes, making dissection more technically difficult...

Increasing evidence supports the idea that bone morphogenetic proteins (BMPs) regulate cartilage maintenance in the adult skeleton. The aim of this study is to obtain insight into the regulation of BMP activities in the adult skeletal system. We analyzed expression of Noggin and Gremlin1, BMP antagonists that are known to regulate embryonic skeletal development, in the adult skeletal system by Noggin-LacZ and Gremlin1-LacZ knockin reporter mouse lines. Both reporters are expressed in the adult skeleton in a largely overlapping manner with some distinct patterns...

PURPOSE: Ideal approaches and materials for reconstruction of large chest wall defects remain a topic of debate. We sought to explore the suitability of a reinforced nanostructured cellulose (NC) patch for chest wall reconstruction in an animal model. MATERIALS AND METHODS: In four domestic pigs, a standardized 10 × 10 cm chest wall defect was created by resecting three rib segments. Subsequently the defect was reconstructed via a biosynthetic NC patch (16 × 12 cm) reinforced by polytetrafluoroethylene mesh...

Millions of years of evolution have fine-tuned the ability of venom peptides to rapidly incapacitate both prey and potential predators. Toxicofera reptiles are characterized by serous-secreting mandibular or maxillary glands with heightened levels of protein expression. These glands are the core anatomical components of the toxicoferan venom system, which exists in myriad points along an evolutionary continuum. Neofunctionalisation of toxins is facilitated by positive selection at functional hotspots on the ancestral protein and venom proteins have undergone dynamic diversification in helodermatid and varanid lizards as well as advanced snakes...

The human ribcage expands and contracts during respiration as a result of the interaction between the morphology of the ribs, the costo-vertebral articulations and respiratory muscles. Variations in these factors are said to produce differences in the kinematics of the upper thorax and the lower thorax, but the extent and nature of any such differences and their functional implications have not yet been quantified. Applying geometric morphometrics we measured 402 three-dimensional (3D) landmarks and semilandmarks of 3D models built from computed tomographic scans of thoraces of 20 healthy adult subjects in maximal forced inspiration (FI) and expiration (FE)...

Adequate surgical resection was required for patients with rib chondrosarcoma. A 61-year-old woman was presented with a palpable chest wall mass. Computed tomography (CT) of the chest revealed an isolated pulmonary nodule about 0.9 cm, and a giant rib tumor about 12 cm × 9 cm which penetrated through the 7(th) rib into thorax. CT reconstruction and simulated surgery was utilized for disease-free surgical margin (R0 resection), then a simultaneous en bloc resection of pulmonary nodule and rib tumor was performed along with chest wall reconstruction under local anesthesia and intravenous sedation without endotracheal intubation...

BACKGROUND: External support has been viewed as an important biomechanical constraint for children with deficits in postural control. Nonlinear analysis of head stability is necessary to confirm benefits of interaction between external trunk support and level of trunk control. OBJECTIVE: To compare the effect of biomechanical constraints (trunk support) on neural control of head stability during development of trunk control. DESIGN: Quasi-experimental repeated measure study...

The serratus anterior is portrayed as a homogeneous muscle in textbooks and during functional activities and rehabilitation exercises. It is unclear whether the serratus anterior is composed of subdivisions with distinctive morphology and functions. The purpose of this study was to determine whether the serratus anterior could be subdivided into different structural parts on the basis of its segmental architectural parameters. Eight formalin-embalmed serratus anterior muscles were dissected and the attachments of each fascicle documented...

BACKGROUND: We implemented expanded screening criteria for blunt cerebrovascular injuries (BCVIs) in an attempt to capture the remaining 20% of patients not historically identified with earlier protocols. We hypothesized that these expanded criteria would capture the additional 20% of BCVI patients not previously identified. METHODS: Screening criteria for BCVI were expanded in 2011 after identifying new injury patterns. The study population included 4 years prior (2007 to 2010; classic) and following (2011 to 2014; expanded) implementation of expanded criteria...

OBJECTIVES: We aimed to estimate the prevalence of abuse in young children presenting with rib fractures and to identify demographic, injury, and presentation-related characteristics that affect the probability that rib fractures are secondary to abuse. METHODS: We searched PubMed/MEDLINE and CINAHL databases for articles published in English between January 1, 1990, and June 30, 2014 on rib fracture etiology in children 5 years or younger. Two reviewers independently extracted predefined data elements and assigned quality ratings to included studies...

A continuous peripheral nerve block (CPNB) consists of a percutaneously inserted catheter with its tip adjacent to a target nerve/plexus through which local anesthetic may be administered, providing a prolonged block that may be titrated to the desired effect. In the decades after its first report in 1946, a plethora of data relating to CPNB was published, much of which was examined in a 2011 Anesthesia & Analgesia article. The current update is an evidence-based review of the CPNB literature published in the interim...
