INTRODUCTION: Severe cases of genu varum represent a major challenge in obtaining normal configuration of the proximal tibia and overall limb alignment. PRESENTATION OF CASE: We performed inverted V-shaped high tibial osteotomy (HTO) by using a locking plate for recurrent severe bilateral tibia vara in a 15-year-old female patient with Turner syndrome. Preoperative medial proximal tibial angle (MPTA) and standing femorotibial angle (FTA) of the right/left legs were 67°/69° and 197°/203°, respectively...

In a double-blind, crossover, randomized and placebo-controlled trial; 28 men and women ingested a placebo (PLA), 3 g of creatine nitrate (CNL), and 6 g of creatine nitrate (CNH) for 6 days. Participants repeated the experiment with the alternate supplements after a 7-day washout. Hemodynamic responses to a postural challenge, fasting blood samples, and bench press, leg press, and cycling time trial performance and recovery were assessed. Data were analyzed by univariate, multivariate, and repeated measures general linear models (GLM)...

CASE: The classic metaphyseal lesion, or corner fracture, is considered a strong indicator of nonaccidental trauma. In the present case, the parents brought their 8-month-old boy to a community hospital after he stopped crawling on the right leg. A knee radiograph demonstrated an isolated metaphyseal lesion, which prompted concern for child abuse. The patient was transferred to the nearest academic medical center; the pediatric radiology expert in child abuse determined that the lesion was a normal variant and not the result of abuse...

CASE: A 64-year-old woman had undergone bilateral total knee arthroplasty in 1998. In 2010, she presented with a large, painless, diaphyseal soft-tissue mass of the lower leg. She indicated that she had no history of knee pain, trauma, or infection. Ultimately, the mass was found to be a synovial fluid-filled cyst that communicated with the knee joint, which was a result of severe osteolysis. CONCLUSION: Large diaphyseal tibial masses in the presence of total knee arthroplasty should raise a high index of suspicion not only for tumors and infections, but also for severe osteolysis...

The first exposure of a rapid displacement of a light touch reference induces an inappropriate balance corrective response during standing in a proportion of participants that is extinguished with repeated exposures. We hypothesized that if the spatial touch reference was critical to performing of a task the evoked response would be more consistently expressed across participants and observed with repeated exposures to the disturbance. To test this, 20 participants received either forward (N = 10) or backward right-touch displacements at right-heel strike during motorized treadmill walking without visual feedback...

STUDY DESIGN: Case report. PURPOSE: To present a rare case of cervical disc herniation concomitant with intradural meningioma which was successfully treated using a single one-stage posterior surgery of tumor resection and transdural discectomy. Coexistence of symptomatic disc herniation and intra-spinal tumor in the same cervical segment is extremely rare. Usually, two-stage anterior and posterior surgeries are needed to treat two conditions, respectively. One-stage posterior surgery to treat two pathologies simultaneously has not been reported in the literature...

Understanding spatial physical habitat selection driven by competition and/or predator-prey interactions of mobile marine species is a fundamental goal of spatial ecology. However, spatial counts or density data for highly mobile animals often (1) include excess zeros, (2) have spatial correlation, and (3) have highly nonlinear relationships with physical habitat variables, which results in the need for complex joint spatial models. In this paper, we test the use of Bayesian hierarchical hurdle and zero-inflated joint models with integrated nested Laplace approximation (INLA), to fit complex joint models to spatial patterns of eight mobile marine species (grey seal, harbor seal, harbor porpoise, common guillemot, black-legged kittiwake, northern gannet, herring, and sandeels)...

Background: Precise regional quantitative assessment of renal function is limited with conventional 99mTc-labeled renal radiotracers. A recent study reported that the positron emission tomography (PET) radiotracer 2-deoxy-2-18F-fluorosorbitol (18F-FDS) has ideal pharmacokinetics for functional renal imaging. Furthermore, 18F-FDS is available via simple reduction from routinely used 2-deoxy-2-18F-fluoro-D-glucose (18F-FDG). We aimed to further investigate the potential of 18F-FDS PET as a functional renal imaging agent using rat models of kidney diseases...

A 63-year-old man presented with an asymptomatic infrarenal abdominal aortic aneurysm. He had scoliosis and atrophic right leg change as sequelae of poliomyelitis. The patient was not a candidate for endovascular aneurysm repair because of anatomic unsuitability. An open surgical repair was performed by the retroperitoneal approach because of severe scoliosis and left lateral aneurysm deviation. To minimize contralateral exposure, the Viabahn stent graft (W. L. Gore & Associates, Flagstaff, Ariz) was inserted in the right external iliac artery and anastomosed with the right expanded polytetrafluoroethylene graft limb...

Physical expressions of affection play a foundational role in early brain development, but the neural correlates of affective touch processing in infancy remain unclear. We examined brain responses to gentle skin stroking, a type of tactile stimulus associated with affectionate touch, in young infants. Thirteen term-born infants aged 11-36days, recruited through the FinnBrain Birth Cohort Study, were included in the study. Soft brush strokes, which activate brain regions linked to somatosensory as well as socio-affective processing in children and adults, were applied to the skin of the right leg during functional magnetic resonance imaging...

OBJECTIVES: Cooling of the lower limb in people with Hereditary and Spontaneous Spastic Paraparesis (pwHSSP) has been shown to affect walking speed and neuromuscular impairments. The investigation of practical strategies which may help to alleviate these problems is important. The potential of superficial heat to improve walking speed has not been explored in pwHSSP. Primary objective was to explore whether the application of superficial heat (hot packs) to lower limbs in pwHSSP improves walking speed...

Sports medical examinations of juvenile athletes provide an opportunity for preventive measures against sports-related diseases. Determining the leg axis deviation as a risk factor for future constraints may offer approaches for such measures. Data were obtained from 789 youth athletes: 166 with coronal plane knee misalignment and 623 without. After a seven-year period, 64 participants (m: 33, f: 31) from both groups were reassessed for the incidence of nonspecific chronic low back pain (CLBP). To distinguish participants with increased risk for CLBP, contingency tables for comparison of expected and joint frequency distribution testing and receivers operating characteristic (ROC) analyses for the weekly training time were conducted...

To maintain muscle mass in older age, several aspects regarding the amount and distribution of protein intake have been suggested. Our objective was to investigate single and combined associations of daily protein intake, evenness of protein distribution across the three main meals, number of meals providing ≥0.4 g protein/kg body weight (BW), and number of meals providing ≥2.5 g leucine, with muscle mass, strength, and power in successful agers. In this cross-sectional study in 97 healthy community-dwelling adults without functional limitations aged 75-85 years, protein intake was assessed using 7-day food records...

Qiuhong Cui, Guillermo C Bazan
Two essential structural elements define a class of materials called conjugated polyelectrolytes (CPEs). The first is a polymer framework with an electronically delocalized, π-conjugated structure. This component allows one to adjust desirable optical and electronic properties, for example the range of wavelengths absorbed, emission quantum yields, electron affinity, and ionization potential. The second defining feature is the presence of ionic functionalities, which are usually linked via tethers that can modulate the distance of the charged groups relative to the backbone...
