BACKGROUND: Chronic recurrent multifocal osteomyelitis (CRMO), also known as chronic nonbacterial osteomyelitis, is a rare, noninfectious inflammatory disorder that causes multifocal bone lesions with swelling and pain. Lytic and sclerotic bone lesions could be found on X-ray. Short tau inversion recovery magnetic resonance imaging (STIR MRI) shows bone marrow oedema, bone expansion, lytic areas and periosteal reaction. CRMO is characterized by periodic exacerbations and remissions of unclear/unknown pathogenesis...

The triangular lattice Na x RhO 2 contains a 4d Rh element with large spin-orbit coupling, and the electron-electron correlation effect is expected to have some novel physical properties. Here we report NaRhO 2 crystal growth by Na 2 CO 3 vapor growth and a series of Na x RhO 2 (0.25 ≤ x ≤ 1) crystals prepared using the chemical desodiation method. Na x RhO 2 reveals a layer structure with the space group R3̅m, and the lattice parameter a evolves from 3.09 to 3.03 Å and c from 15.54 to 15.62 Å when x decreases from 1...

PURPOSE: X-ray coherent scattering tomography is a powerful tool in discriminating biological tissues and bio-compatible materials. Conventional X-ray scattering tomography framework can only resolve isotropic scattering profile under the assumption that the material is amorphous or in powder form, which is not true especially for biological samples with orientation-dependent structure. Previous tomography schemes based on X-ray coherent scattering failed to preserve the scattering pattern from samples with preferred orientations, or required elaborated data acquisition scheme, which could limit its application in practical settings...

Femur shaft fractures in infants are rare and associated with abuse or fall from heights. The fracture is often easy to recognize on X-ray, however, the determination of the indication can be difficult. It is important to pay attention to pain signals from the extremity and the objective findings, such as a swollen and tight thigh. Early recognition of the fracture is of importance to the prognosis and to detection of possible violence resulting in battered child syndrome. Exploration for injuries of the extremities is of utmost necessity in these cases, despite the absence of trauma in the anamnesis...

AIM: To determine whether the placement of a post-pyloric feeding tube (PPFT) can be taught safely and effectively to a critical care dietitian. METHODS: This is a prospective observational study conducted in an adult intensive care unit (ICU). The intervention consisted of 19 attempts at post-pyloric intubation by the dietitian. The 10 'learning' attempts were performed by the dietitian under the direction of an experienced (having completed in excess of 50 successful tube placements) user...

The decline in amphibian populations is a critical threat to global biodiversity, and pesticide pollution is considered as one of the major factors. Although effects of single pesticides on amphibians have been documented, toxicological interactions prevailing in mixtures of pesticides have not been well elucidated. Strobilurin and succinate dehydrogenase inhibitor (SDHI) fungicides are new types of commonly used pesticides. In this study, effects of three strobilurins (pyraclostrobin, trifloxystrobin and azoxystrobin), two SDHIs (isopyrazam and bixafen), and their mixtures on X...

An accurate, sensitive and selective method is developed for determination of ergocalciferol (vitamin D2) in human plasma using LC-MS/MS. After liquid-liquid extraction with n-hexane, ergocalciferol was derivatized by reacting with 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD), a strong dienophile based on Diels-Alder reaction. Ergocalciferol and its deuterated internal standard, ergocalciferol-d6, were analyzed on X Select CSH C18 (100 mm×4.6 mm, 2.5 µm) column using acetonitrile and 0.1% (v/v) formic acid in water containing 0...

Context: Cervical spondylotic myelopathy (CSM) is a progressive disease that can result in significant disability. Single-level stenosis can be effectively decompressed through either anterior or posterior techniques. However, multilevel pathology can be challenging, especially in the presence of significant spinal stenosis. Three-level anterior decompression and fusion are associated with higher nonunion rates and prolonged dysphagia. Posterior multilevel laminectomies with foraminotomies jeopardize the bone stock required for stable fixation with lateral mass screws (LMSs)...

Plantar fasciitis is the most common cause of heel pain in adults. It involves painful symptoms occurring along the plantar fascia with or without the presence of a bony heel spur. Heel pain that occurs on standing after a prolonged non-weight-bearing period is a prominent symptom of plantar fasciitis. On physical examination, palpation along the medial plantar calcaneal region reproduces the painful symptoms. Routine imaging studies usually are not necessary but can be used to rule out pathologies or confirm chronic or recalcitrant plantar fasciitis...

We have devised a medial peri-articular osteotomy, the distal tibial oblique osteotomy (DTOO), and have used this technique since 1994 for ankle osteoarthritis of advanced and late stages associated with varus inclination. This report describes the surgical technique and its applicability. DTOO can be used for cases of varus ankle osteoarthritis with a range of the ankle joint movement of at least 10° or more. The osteotomy is obliquely directed cut across the distal tibia from proximal-medial to distal lateral and is of an opening-wedge type with the centre of rotation coincident with the centre of the tibiofibular joint...

A major challenge in cross-linking/mass spectrometry (MS) is targeting carboxyl functions in proteins under physiological conditions that do not disturb the protein's conformation. Cross-linking of glutamic acid and aspartic acid residues in proteins will greatly expand the scope of structural mass spectrometry. We discovered that carboxyl-reactive cross-linkers have already been employed for many years in cross-linking/MS studies - yet in a completely different context. Diazirine-based cross-linkers, such as photo-methionine and succin-imidyldiazirine cross-linkers, are currently considered to react non-specifically upon UV-A photoactivation with all 20 proteinogenic amino acids through a reactive carbene that inserts mainly into C-H bonds...

BACKGROUND: Acetabular fractures are amongst the most challenging fractures to treat because of complex anatomy. Open reduction and internal fixation remains the standard treatment for displaced acetabular fractures to achieve anatomical reduction as in any other intra-articular fracture. Patient-specific pre-contoured reconstruction plate template made by a pre-operative virtual surgical planning can be useful to respect patient's morphology, reduce surgical invasiveness and simplify the surgical procedure...

A 77-year-old man sustained an acetabular fracture after falling from a staircase and landing on his right side. He fractured the anterior column of his acetabulum and the quadrilateral plate. He underwent a single-stage open reduction and internal fixation of the fracture combined with a dual mobility total hip arthroplasty (THA). He sustained a traumatic hip dislocation 1 month postoperatively. Closed reduction was attempted at another hospital, and the femoral stem was pulled out. We believe this was caused by the polyliner being hitched either to the acetabular cup or in the soft tissues around the ilium...

BACKGROUND: Symptomatic os acromiale are fairly uncommon, and treatment has included fragment excision, decompression, and open reduction and internal fixation. Nonunion rates as high as 40% have been reported after fixation of os acromiale. This study assessed whether union of an os acromiale could be reliably achieved without the use of an iliac crest bone graft. METHODS: This was a retrospective study of 32 consecutive shoulders that were treated with screw fixation and a local bone graft or iliac crest bone graft...

OBJECTIVES: The aims of this study were to describe radiation level at our institution during transcatheter patent ductus arteriosus occlusion and to evaluate the components contributing to radiation exposure. BACKGROUND: Transcatheter occlusion relying on X-ray imaging has become the treatment of choice for patients with patent ductus arteriosus. Interventionists now work hard to minimise radiation exposure in order to reduce risk of induced cancers. METHODS: We retrospectively reviewed all consecutive children who underwent transcatheter closure of patent ductus arteriosus from January 2012 to January 2016...

The combination of radiotherapy and pharmacological inhibition of cellular signal transduction pathways offers promising strategies for enhanced cancer cell inactivation. However, the molecular effects of kinase inhibitors especially on DNA damage detection and repair after X-irradiation have to be understood to facilitate the development of efficient and personalized treatment regimens. Therefore, we applied differential proteomics for analyzing inhibitor-induced changes in either chromatin-bound or phosphorylated nuclear proteins...
