This report presents a rare case of isolated non-cleft velopharyngeal dysfunction (VPD). An eight-year-old child presented 1. a phenotypically unique band-gap pattern of the velar musculature with anteroposterior insertion; 2. a mosaic partial trisomy on chromosome 19 as well as microduplications on chromosomes 8 and 22. Following cytogenetic analysis, microduplication on chromosome 8 was found in another member of her family. A family history of VPI with hypernasality and nasal regurgitation was reported over three different generations on the patient's maternal side...

Detailed characterization of damage and rupture mechanics of arteries is one the current challenges in vascular biomechanics, which requires developing suitable experimental approaches. This paper introduces an approach using in situ tensile tests in an X-ray micro-tomography setup to observe mechanisms of damage initiation and progression in medial layers of porcine aortic samples. The technique requires the use of sodium polytungstate as a contrast agent, of which the conditions for use are detailed in this paper...

Dance involves a high volume of aesthetic, stretch-shortening cycle (SSC) actions, which may cause unique adaptations to performance. The strength dancers possess to withstand such frequency of SSCs remains elusive. The extensive training that dancers experience from a young age, however, yields anatomical and strength development that may contrast with that of untrained individuals. Therefore, the purpose of this study was to investigate differences in musculo-articular stiffness and maximal isometric plantar flexion and knee extension force between dancers and untrained individuals...

BACKGROUND: Physical frailty and loss of mobility in elderly individuals lead to reduced independence, quality of life, and increased mortality. Vitamin B12 deficiency has been linked to several age-related chronic diseases, including in the musculo-skeletal system, where vitamin B12 deficiency is generally believed to be linked to poor nutritional intake. In the present study, we asked whether aging and frailty associate with altered vitamin B12 homeostasis in humans and investigated the underlying molecular mechanisms using preclinical models...

BACKGROUND: Low back pain (LBP) is a complex health care issue that often involves multiple providers across various care settings. Health information technology (HIT) holds promise to improve care delivery by providing infrastructure for communication, clinical documentation, and management of patient data. Standardized terminology is essential for interoperability and enables evaluation of clinical data generated by documentation in an electronic health record (EHR). OBJECTIVE: The purpose of this study was to demonstrate the feasibility of mapping evidence-based practice for conservative management of low back pain to the Omaha System and foster inter-professional communication and collaboration among diverse practitioners and patients...

Skeletal muscle (SM) is the most abundant tissue and the largest reservoir of protein in the body. It transports glucose in an insulin dependent manner by the glucose transporter type 4 (GLUT4) and contributes in the maintenance of serum amino acids concentration. By its mass and energetic requirements, it is fundamental for the systemic metabolic balance. In the present work, we present the effect of gestational undernourishment (GU) on the mechanical and metabolic properties of SM at birth and in old age in an animal model...

In this work, we extend our previous esophageal transport model using an immersed boundary (IB) method with discrete fiber-based structural model, to one using a continuum mechanics-based model that is approximated based on finite elements (IB-FE). To deal with the leakage of flow when the Lagrangian mesh becomes coarser than the fluid mesh, we employ adaptive interaction quadrature points to deal with Lagrangian-Eulerian interaction equations based on a previous work (Griffith and Luo [1]). In particular, we introduce a new anisotropic adaptive interaction quadrature rule...

Human motor function emerges from the interaction between the neuromuscular and the musculoskeletal systems. Despite the knowledge of the mechanisms underlying neural and mechanical functions, there is no relevant understanding of the neuro-mechanical interplay in the neuro-musculo-skeletal system. This currently represents the major challenge to the understanding of human movement. We address this challenge by proposing a paradigm for investigating spinal motor neuron contribution to skeletal joint mechanical function in the intact human in vivo...

Embryonic muscular activity (EMA) is involved in the development of several distinctive traits of birds. Modern avian diversity and the fossil record of the dinosaur-bird transition allow special insight into their evolution. Traits shaped by EMA result from mechanical forces acting at post-morphogenetic stages, such that genes often play a very indirect role. Their origin seldom suggests direct selection for the trait, but a side-effect of other changes such as musculo-skeletal rearrangements, heterochrony in skeletal maturation, or increased incubation temperature (which increases EMA)...

Chronicity and recurrence in musculoskeletal shoulder pain are highly prevalent and can possibly be attributed to the concept of central sensitization. Available studies suggest a role for central sensitization in explaining chronic shoulder pain, but so far a comprehensive quantitative sensory testing (QST) protocol has not been used. The aim of this study was to gain knowledge on sensory processing and central pain modulatory mechanisms in patients suffering from chronic shoulder pain using such a QST protocol...

INTRODUCTION: Public expectations regarding access to the emergency department (ED) challenges providers and policy makers with finite resources being stretched beyond capacity. To enable education of a greater numbers of doctors the format of the medical internship in Australia has changed and assumes that sufficient supervision is provided to interns to enable image interpretation skills development. Furthermore this assumes that appropriate foundational skills are established during undergraduate education...

REVIEW
E Carlos Rodriguez-Merchan
Musculo-skeletal pain treatment is inadequate in many haemophilic patients. Analgesics are used only by 36% of adult patients. FVIII/FIX intravenous infusion is mainly used to lessen pain, followed in frequency by usage of NSAIDS (primarily COX-2 inhibitors). In about 30% of patients, pain continues after infusion of F VIII/IX. In acute haemarthroses pain treatment must continue until total disappearance (checked by ultrasonography) and include haematologic treatment, short-term rest of the involved joint, cryotherapy, joint aspiration and analgesic medication (paracetamol in mild pain, metamizole for more intense pain, and in a few precise patients, soft opioids such as codeine or tramadol)...

BACKGROUND: Desmoid tumors are borderline tumors of the connective tissue, arising in the musculo-aponeurotic stromal elements. A desmoid tumor (DT) has an infiltrative and locally aggressive growth pattern and usually does not metastasize; however, it has a high recurrence and complication rate. DT located in the breast (BDT) represents a rare extra-abdominal form. Recently, the presence of breast silicone implants was suggested by several researchers as a risk factor for developing BDT...

The musculo-skeletal response of athletes to various activities during training exercises has become a critical issue in order to optimize their performance and minimize injuries. However, dynamic and kinematic measures of an athlete's activity are generally limited by constraints in data collection and technology. Thus, the choice of reliable and accurate sensors is crucial for gathering data in indoor and outdoor conditions. The aim of this study is to validate the use of the accelerometer of a high sampling rate ( 1344 Hz ) Inertial Measurement Unit (IMU) in the frame of running activities...

INTRODUCTION: Cosmetic injections of dermal fillers or fat could cause ophthalmic artery embolism and even blindness, the high-risk regions of which are considered glabellar, nasal dorsum, and nasolabial fold. Understanding anatomy of the related arteries is important for a physician to safely perform filler injections. To investigate the mechanisms of ophthalmic artery embolism following the injections, cadaver anatomy was studied. METHODS: Ophthalmic artery, facial artery, their branches, and anastomoses among them were anatomized in 12 fresh cadavers...

BACKGROUND: Some intractable cases of postcraniotomy infection, which can involve compromised skin, an open frontal air sinus, and residual epidural dead space, have been reported. In such cases, reconstructing the scalp and skull is challenging. METHODS: Between 2009 and 2016, the author treated 12 patients with recalcitrant postcraniotomy surgical site infections with latissimus dorsi (LD) free flaps. The patients' ages ranged from 37 to 79 years (mean, 63.5 years), and their underlying diseases included subarachnoid hemorrhaging (n = 5), brain tumors (n = 4), and cerebral arteriovenous malformations (n = 3)...

The lymphatic system in teleost fish has genetic and developmental origins similar to those of the mammalian lymphatic system, which is involved in immune response and fluid homeostasis. Here, we show that the lymphatic system of tunas functions in swimming hydrodynamics. Specifically, a musculo-vascular complex, consisting of fin muscles, bones, and lymphatic vessels, is involved in the hydraulic control of median fins. This specialization of the lymphatic system is associated with fish in the family Scombridae and may have evolved in response to the demand for swimming and maneuvering control in these high-performance species...
