BACKGROUND: Our previous study showed that muscle-derived cells could regenerate strong engineered tendon with better tissue structure. However, little was known about the mechanism of neo-tendon built by muscle-derived cells, and the development and maturation of the cells. We hypothesized that mechanical loading modulated this process. The aim of this study is to investigate whether mechanical loading could regulate muscle-derived cells engineered tendon formation and maturation. METHODS: Muscle-derived cells were isolated, expanded and seeded on polyglycolic acid (PGA) fibers that formed a cell-scaffold complex...

The abdominal muscles are important for the stability of the lumbar region through the thoracolumbar fascia (TLF). However, there is not full agreement regarding the posterior continuity of the external abdominal oblique muscle (EO) with the TLF. To clarify this point, computed tomography (CT) images from 10 cadavers and 27 subjects were used to evaluate the continuity of the TLF with the abdominal muscles. The width of the fascial continuity of the EO with the posterior layer of TLF along the posterior border of the EO was also measured (40...

Trichinellosis is a worldwide zoonosis with genotypes affecting different domestic and wild animals and is widely distributed throughout the world. Species and genotypes of this genus affecting different animals have been identified. Despite its occurrence in Sub-Saharan countries, the presence of trichinellosis in Botswana is yet to be confirmed. The objective of this study was to determine the prevalence of Trichinella infection in domestic pigs slaughtered at an abattoir in Gaborone, Botswana. Of the 111 pig carcasses selected, 5 g of crus of the diaphragm was collected from each carcass, trimmed of all fat and fascia and then cut into 1- to 2-g samples...

BACKGROUND: The existence of continuity between fascia and muscles that may be anatomically distant from each other is emphasized in the tensegrity principle. Despite evidence from in vitro studies, there is a dearth of literature concerning the in vivo behavior of these connections. AIM: To compare the effect of Static Stretching (SS) of hamstrings with remote Myofascial Release (MFR) (bilateral plantar fascia and suboccipital region) and a combination of SS and remote MFR on hamstring flexibility...

PURPOSE OF REVIEW: Blepharoptosis is a common problem encountered in the pediatric ophthalmology clinic. The presentation is obvious to both parents and referring physicians and often prompts urgent consultation. The current classification and management of childhood ptosis will be reviewed. RECENT FINDINGS: Recent refinements in techniques utilizing new materials hold promise for better, more predictable outcomes and improved long-term results. Autogenous tensor tendon fascia lata harvested from the patient's thigh remains the gold standard for many ptosis surgeons in frontalis suspension; however, other materials are commonly utilized, including silicone rod, Gore-Tex (ePTFE; W...

OBJECTIVES: Subcutaneous involvement, including calcinosis and panniculitis, is a more common complication in juvenile dermatomyositis (JDM) than in adult dermatomyositis. Magnetic resonance imaging (MRI) is useful for evaluating disease distribution. We investigated the clinical significance of subcutaneous involvement in JDM. METHODS: Thighs and hips in 18 newly diagnosed JDM patients were evaluated with fat-suppression MRI. Bilateral muscle, fascial and subcutaneous fat involvement were scored from 0-8 points according to the severity of distribution on MRI...

BACKGROUND: Intradural disc herniation is a rare entity with less than 0.3-1% of all disc herniations and at an L2-L3 level even rarer. The dural defects repairs on ventral aspect are technically challenging and may not be possible after durotomy hence many authors have placed fascia, muscle, or plugging by the hemostatic material. The surgical treatment of intradural disc herniation is usually posterior open surgery with formal durotomy to remove the disc fragments with good to fair results while the poorer outcome in late-presenting cases...

Breast augmentation with implants is one of the most commonly performed plastic surgery procedures. The goal of the operation is to increase the size, shape or fullness of the breast. It is accomplished by placing silicone, saline or alternative composite breast implants under the chest muscles, fascia or the mammary gland. This type of operation is no exception concerning the occurrence of complications. The most common early complications include an infectious process, a seroma, and a hematoma, and the late ones are capsular contracture, reoperation, implant removal, breast asymmetry, and rupture or deflation of the implant...

The individual appearance and facial expression are based on the musculoskeletal system of the face. The bones of the face contribute to the anterior portion of the skull. This region is also referred to as the facial skeleton or viscerocranium. The muscles of the face include all mimetic muscles innervated by the cranial nerve VII (facial nerve). Two masticatory muscles (masseter, temporalis) that are supplied by the motoric portion of the cranial nerve V3 (mandibular nerve) also contribute to the contour of the face...

Eosinophilic fasciitis (EF) is an uncommon connective tissue disease characterized by abrupt onset of edema, followed by progressive induration of primarily the distal extremities. Patients may exhibit inflammatory arthritis, joint contractures, decreased mobility, and nerve entrapment. Almost half of patients with EF may have coexisting morphea plaques. Classic laboratory studies display peripheral eosinophilia, hypergammaglobulinemia, and elevated inflammatory markers. EF is included in the spectrum of scleroderma like disorders and may be difficult to distinguish from other sclerosing skin disorders...

Lateral abdominal wall defects, while rare, present a more challenging problem than commonly encountered ventral defects due to the complexity of the anatomy, physiologic forces, and impact of muscle denervation. The lateral abdominal wall encompasses a large surface area ranging from the costal margin superiorly to the iliac crest inferiorly and from the linea semilunaris anteriorly to the paraspinous musculature posteriorly. The ratio of muscle to fascia/aponeurosis is much higher, which makes repair through muscle tissue versus fascia less secure...
