OBJECTIVE: The purpose of this study was to describe the three-dimensional deformities of midshaft clavicle fractures, which had been treated nonoperatively, using computed tomography (CT) surface matching. METHODS: Twenty-one patients with unilateral midshaft clavicle fracture, who had been treated nonoperatively, were enrolled and evaluated retrospectively. The three-dimensional deformity of the fractured clavicle was evaluated by CT surface matching. CT scans of 21 age- and sex-matched patients with initial traumatic shoulder dislocation or proximal humeral fracture were enrolled as a control group, and the differences in three-dimensional deformities and lengths of the clavicles between the fracture group and the control group were evaluated...

OBJECTIVE: Prediction of walking tasks in powered leg prostheses is an important problem in the development of biomimetic prosthesis controllers. This article proposes a novel method to predict upcoming walking tasks by estimating the translational motion of leg joints using an inertial measurement unit. METHODS: We asked six subjects with unilateral transtibial amputations to traverse flat ground, ramps, and stairs using a powered prosthesis while inertial signals were remotely collected...

BACKGROUND: We compared the long-term clinical and ultrasonographic effects of radial extracorporeal shockwave therapy (rESWT) versus ultrasound-guided corticosteroid injection treatment in patients with plantar fasciitis unresponsive to conservative therapy. METHODS: Seventy-two patients with unilateral plantar fasciitis were randomized to receive either rESWT (three times once per week) (n = 36) or corticosteroid treatment (a single 1-mL dose of betamethasone sodium plus 0...

In plants, cell-cell recognition is a crucial step in the selection of optimal pairs of gametes to achieve successful propagation of progeny. Flowering plants have evolved various genetic mechanisms, mediated by cell-cell recognition, to enable their pistils to reject self-pollen, thus preventing inbreeding and the consequent reduced fitness of progeny (self-incompatibility, SI), and to reject foreign pollen from other species, thus maintaining species identity (interspecific incompatibility)(1). In the genus Brassica, the SI system is regulated by an S-haplotype-specific interaction between a stigma-expressed female receptor (S receptor kinase, SRK) and a tapetum cell-expressed male ligand (S locus protein 11, SP11), encoded by their respective polymorphic genes at the S locus(2-6)...

Hypertrophic olivary degeneration (HOD) is a rare trans-synaptic neuronal degeneration of the inferior olivary nucleus caused by an injury to the dentato-rubro-olivary connection, also known as Guillain-Mollaret triangle. It leads to hypertrophy of the affected nucleus rather than atrophy and is characterized by hyperintensity on T2-weighted images. Unilateral and bilateral cases are described. We present a case of a 70-year-old patient affected by a tumor inside the fourth ventricle who suffered from diplopia and right seventh cranial nerve palsy...

BACKGROUND: Current outcome measures used in upper limb myoelectric prosthesis studies include clinical tests of function and self-report questionnaires on real-world prosthesis use. Research in other cohorts has questioned both the validity of self-report as an activity assessment tool and the relationship between clinical functionality and real-world upper limb activity. Previously,(1) we reported the first results of monitoring upper limb prosthesis use. However, the data visualisation technique used was limited in scope...

Contralateral prophylactic mastectomy use has increased over the past decades among women with early-stage breast cancer. Racial differences in contralateral prophylactic mastectomy use are well described, but with unclear causes. This study examined contralateral prophylactic mastectomy use among black and white women and the contribution of differences in perceived risk to differences in use. We surveyed women diagnosed with early-stage unilateral breast cancer between ages 41-64 in Pennsylvania and Florida between 2007-2009 to collect data on breast cancer treatment, family history, education, income, insurance, and perceived risk...

Multiple endocrine neoplasia type 2A (MEN2A) is a rare syndrome which main component is medullary thyroid carcinoma (MTC). The natural history of MTC is mainly determined by RET mutations. The second main component of MEN2A is pheochromocytoma. The latest American Thyroid Association guidelines suggested ages to begin biological screening for pheochromocytoma depending on RET mutations. However, other factors could modify the natural history of pheochromocytoma. We collected data from a large international cohort, based on 812 patients, and grouped them according to 4 geographical areas: South America, Southern Europe, Central Europe and Western Europe...

BACKGROUND: Standard mastectomy has long been the recommended breast surgical treatment for non-metastatic inflammatory breast cancer (IBC). The objective of this population-based study was to evaluate the significance of various breast surgical treatments for this highly aggressive subtype. METHODS: The Surveillance, Epidemiology, and End Results program registry was searched to identify women with non-metastatic IBC receiving standard treatment including breast surgery, radiation therapy and chemotherapy diagnosed between 1998 and 2013...

We hypothesized that cochlear frequency discrimination occurs through medial olivocochlear efferent (MOCE)-induced alterations in outer hair cell (OHC) electromotility, which is independent from basilar membrane traveling waves. After obtaining informed consent, volunteers with normal hearing (n = 10; mean age: 20.6 ± 1.2 years) and patients with unilateral deafness (n = 10; mean age: 30.2 ± 17.9 years) or bilateral deafness (n = 8; mean age: 30.7 ± 13.8 years) underwent a complete physical and audiological examination, and audiological tests including transient evoked otoacoustic emission and spontaneous otoacoustic emission (TEOAE and SOAE, respectively)...

INTRODUCTION: Traumatic spinal subdural hematoma involving the retroclival region and upper cervical spine is a rare pathology. To our knowledge, there have only been two prior cases in an adult trauma patient. We describe a patient with pre-existing Chiari 1 malformation, who recently sustained a unilateral Type 1 OCF (occipital condyle fracture) with associated disruption of the tectorial membrane and transverse ligament, that returned with a retroclival subdural hematoma extending down to C7, causing spinal cord compression and symptomatic obstructive hydrocephalus...

Hollow organs (e.g. heart) experience pressure-induced mechanical wall stress sensed by molecular mechano-biosensors, including mechanosensitive ion channels, to translate into intracellular signaling. For direct mechanistic studies, stretch devices to apply defined extensions to cells adhered to elastomeric membranes have stimulated mechanotransduction research. However, most engineered systems only exploit unilateral cellular stretch. In addition, it is often taken for granted that stretch applied by hardware translates 1:1 to the cell membrane...

Hypoxic-ischemic (HI) brain injury in newborns is associated with high morbidity and mortality, with many babies suffering neurological deficits. Recently, we showed that hypoxic postconditioning (PostC) immediately post injury can protect against HI up to one week in neonatal rats. Here, we aimed to examine whether long term functional deficits were also improved by PostC. Sprague-Dawley rats were assigned to control (C) or HI group on postnatal day 7 (P7). The HI group underwent unilateral carotid artery occlusion followed by hypoxia (7% oxygen, 3h)...

BACKGROUND CONTEXT: Transforaminal lumbar interbody fusion (TLIF) and posterior lumbar interbody fusion (PLIF) are both frequently used as surgical treatment for lumbar spondylolisthesis. Due to the unilateral transforaminal route to the intervertebral space used in TLIF, opposed to the bilateral route used in PLIF, TLIF could be associated with fewer complications, shorter duration of surgery, and less blood loss, while effectiveness of both techniques on back and/or leg pain is equal...
