BACKGROUND: Pubic symphysis rupture significant enough to cause serious complications or require surgical intervention is exceedingly rare. Here we review the literature and examine the details of a unique presentation. CASE: A 27-year-old woman presented in labour at 34+6 weeks gestation after an uncomplicated monochorionic-diamniotic twin pregnancy. After vaginal delivery, she developed a substantial labial hematoma. Hours later, she became hemodynamically unstable...

BACKGROUND: Umbilical arterial catheter (UAC) insertion is a common procedure in the neonatal intensive care unit (NICU). Correct placement of the tip of the UAC at first attempt minimises handling of the infant and reduces the risk of infection and complications. We aimed to determine the accuracy of 11 published formulae to guide UAC placement. METHODS: This was a one-year prospective observational study in a tertiary NICU. Clinicians used their preferred formula for UAC insertion, with X-rays performed immediately post-procedure to check the tip position...

From the earliest studies of doctor-patient interaction (Byrne & Long, 1976), it has been recognized that treatment recommendations may be expressed in more or less authoritative ways, based on their design and delivery. There are clear differences between I'm going to start you on X and We can give you X to try and Would you like me to give you X? Yet little is known about this variation, its contexts, or its consequences. In this paper, we develop a basic taxonomy of treatment recommendations in primary care as a first step toward a more comprehensive investigation...

A major challenge to achieve effective X-ray radiation therapy is to use a relatively low and safe radiation dose. Various radiosensitizers, which can significantly enhance the radiotherapeutic performance, have been developed. Gold-based nanomaterials, as a new type of nanoparticle-based radiosensitizers, have been extensively used in researches involving cancer radiotherapy. However, the cancer therapeutic effect using the gold nanoparticle-based radiotherapy is usually not significant because of the low cellular uptake efficiency and the autophagy-inducing ability of these gold nanomaterials...

In glassy substances and biological media, dynamical transitions are observed in neutron scattering that manifests itself as deviations of the translational mean-squared displacement, 〈x(2)〉, of hydrogen atoms from harmonic dynamics. In biological media, the deviation occurs at two temperature intervals, at ∼100-150 K and at ∼170-230 K, and it is attributed to the motion of methyl groups in the former case and to the transition from harmonic to anharmonic or diffusive motions in the latter case. In this work, electron spin echo (ESE) spectroscopy-a pulsed version of electron paramagnetic resonance-is applied to study the spin relaxation of nitroxide spin probes and labels introduced in molecular glass former o-terphenyl and in protein lysozyme...

Conventional documentation of surgical procedures using only pre- and postoperative X-ray images and possibly a few intra-operative pictures does not allow secondary analysis of the technical performance in detail. In particular, the quality of the handling of tissues and surgical tools cannot be judged «post hoc», i.e. after the end of the surgical procedure. The invasiveness of the surgical act cannot yet be quantified. Surrogate invasiveness indices have therefore been developed. Furthermore, conventional documentation does not allow evaluation of the proper use of the C-arm both technically and with regard to fluoroscopy time...

PURPOSE OF THE STUDY In developing new or modifying the existing surgical treatment methods of spine conditions an integral part of ex vivo experiments is the assessment of mechanical, kinematic and dynamic properties of created constructions. The aim of the study is to create an appropriately validated numerical model of canine cervical spine in order to obtain a tool for basic research to be applied in cervical spine surgeries. For this purpose, canine is a suitable model due to the occurrence of similar cervical spine conditions in some breeds of dogs and in humans...

BACKGROUND: Patients with severe cervical multilevel stenosis and an adequate lordotic curvature often undergo multilevel laminectomies with posterior instrumented fusions. Although the "gold standard" for the fusion mass remains iliac crest autograft, many require additional volume provided by bone graft expanders. Here, we studied the fusion rates for 32 patients undergoing multilevel cervical laminectomy and vertex/rod/eyelet/titanium cable fusions utilizing lamina/iliac autograft and the bone graft expander Nanoss (RTI Surgical, Alachua, FL, USA) with autogenous bone marrow aspirate (BMA)...

INTRODUCTION: Since the National Lung Screening Trial demonstrated the utility of low-dose computed tomography screening for lung cancer, the detection rate of ground-glass nodules (GGNs) has increased. Endobronchial ultrasound with a guide sheath (EBUS-GS) is widely performed to diagnose peripheral pulmonary lesions, but there are not enough reports on the predictive ability of EBUS-GS in diagnosing GGNs. The aim of this study is to investigate the predictive factors for a successful diagnostic bronchoscopy for GGNs...

Through the substitution of Li with Na in Li6C60, we synthesized a series of mixed alkali cluster intercalated fullerides, NaxLi6-xC60. These compounds share lattices of Na6C60 and Li6C60 with a cubic parameter linearly dependent on x. H2 absorption and desorption were studied by means of charge/discharge kinetic measurements and coupled calorimetric-manometric evaluation. By varying the stoichiometry, we found the best compromise among the absorption rate, temperature and amount of hydrogen for x = 0.5 and 1...

PURPOSE: To evaluate if herpes zoster virus (HZV) reactivation may be considered in the aetiology of cervical radiculopathy. METHODS: The study group was composed of 110 patients (52 M-58F;mean age ± SD:46.5 ± 6.12; range:40-73) with a clinical diagnosis of cervical radiculopathy. Patients with signs of chronic damage on neurophysiological studies were submitted to an X-ray and to an MRI of the cervical spine in order to clarify the cause of the cervical radiculopathy and were investigated for a possible reactivation of HZV; HZV reactivation was considered as "recent" or "antique" if it occurs within or after 24 months from the onset of symptoms, respectively...

BACKGROUND: Extracorporeal membrane oxygenation is an established life-saving procedure for severe acute respiratory failure due to various causes. In general, the duration of extracorporeal membrane oxygenation ranges from 1 to 2 weeks, with withdrawal recommended if no improvement is noted. We report a successful case of long-term extracorporeal membrane oxygenation management for respiratory failure due to invasive pulmonary Aspergillus infection. CASE PRESENTATION: A 64-year-old Asian man with no previous underlying medical conditions was transferred to our hospital for fever and dyspnea...

In this paper, we describe a shear horizontal surface acoustic wave (SH-SAW) immunosensor that utilizes induce agitation by a Rayleigh surface acoustic wave (R-SAW) on an X-cut 148-Y LiTaO3 substrate. On this substrate, SH-SAWs and R-SAWs with different frequencies can be effectively generated at an interdigital transducer (IDT). First, to consider the power flow angles of SH-SAWs and R-SAWs on this substrate, 360 MHz delay lines with six different tilt angles were designed and fabricated. From the experiments, an optimal power flow angle of 9° for the SH-SAW on this substrate is obtained...

We report a new 'pure-shift' method, termed 'SHARPER' (Sensitive, Homogeneous And Resolved PEaks in Real time) de-signed for the analysis of reactions and equilibria by NMR. By focusing on a single selected signal, SHARPER removes all heteronuclear couplings of a selected nucleus without the need to pulse on X channels, thus overcoming hardware limitations of conventional spectrometers. A more versatile decoupling scheme, termed 'sel-SHARPER', removes all heteronuclear and homonuclear couplings of the selected signal...

BACKGROUND: Cervical total disc replacement (TDR) is an established alternative to anterior cervical discectomy and fusion (ACDF) with excellent long-term outcomes and low failure rates. Cases of implant failure and migration are scarce and primarily limited to several years postoperatively. The authors report a case of anterior extrusion of a C4-C5 ProDisc-C (DePuy Synthes, West Chester, PA, USA) cervical artificial disc (CAD) 14 months after placement due to minor trauma. CASE DESCRIPTION: A 33-year-old female who had undergone C4-C5 CAD implantation presented with neck pain and spasm after experiencing a paragliding accident...

The study aimed to evaluate biomarkers facilitating early diagnosis of axial spondyloarthritis (axSpA) and correlations between them and disease activity parameters and imaging indexes. Patients with low back pain (LBP) (≥3 months, ≤2 years, onset ≤45 years) participating in the Italian arm of the SpondyloArthritis-Caught-Early SPACE study underwent a physical examination, questionnaires, laboratory tests, X-rays and MRI of the spine and sacroiliac joints (SIJ). An expert rheumatologist formulated axSpA diagnosis in accordance with Assessment of SpondyloArthritis International Society (ASAS) criteria...

Actually, pilon fractures are classified according to AO and Ruedi Allgower classification systems based on X-rays. These classifications are less reproducible and do not provide necessary information for proper surgical planning. Aim of the study is to (1) propose a new classification system based on CT scan; (2) to check the prognostic value of this classification and (3) to evaluate its reliability and (4) reproducibility. We retrospectively reviewed 71 cases of pilon fracture. All fractures were classified according to AO, Ruedi Allgower and new proposed classification system by 5 surgeons...

David Van der Heggen, Jonas J Joos, Diana C Rodríguez Burbano, John A Capobianco, Philippe F Smet
The performance of a persistent phosphor is often determined by comparing luminance decay curves, expressed in cd/m 2 . However, these photometric units do not enable a straightforward, objective comparison between different phosphors in terms of the total number of emitted photons, as these units are dependent on the emission spectrum of the phosphor. This may lead to incorrect conclusions regarding the storage capacity of the phosphor. An alternative and convenient technique of characterizing the performance of a phosphor was developed on the basis of the absolute storage capacity of phosphors...

PURPOSE: Dedicated tumor feeding vessel detection software (TFVDS) using cone beam CT has shown a higher sensitivity to detect tumor feeding vessels during hepatic arterial embolization (HAE) of hepatocellular carcinoma (HCC) compared to 2D imaging. Our primary hypothesis was that HCC tumors treated with HAE guided by a TFVDS would show more complete response (CR) than when treated with 2D imaging alone. Secondary analysis of the impact on X-ray exposure was performed. MATERIALS AND METHODS: Nineteen males and 8 females (median age: 69 year, 46-85) with 44 tumors (median size: 38 mm, 6-100) treated with selective HAE between January 2013 and December 2014 were included...

We aimed to determine whether bone marrow edema (BME) in acute traumatic scaphoid fracture could be demonstrated with dual-energy CT (DECT) using MRI as the gold standard. In recent years, virtual non-calcium (VNCa) images have been used to demonstrate BME in trauma cases, for example, in vertebral compression fractures, hip trauma to detect occult fractures and knee fractures. We present three cases of acute scaphoid trauma. Two patients had subtle or invisible fractures on x-ray and conventional CT images, while DECT VNCa images clearly visualized the BME, which was confirmed by MRI...
