BACKGROUND AND AIMS: Gamma-hydroxybutyrate (GHB) detoxification procedures have been insufficiently studied for effectiveness and safety. Based on case reports, benzodiazepines are generally regarded as first-choice agents in GHB detoxification. Detoxification by titration and tapering (DeTiTap) with pharmaceutical GHB in an open-label consecutive case series of 23 GHB-dependent patients showed to be feasible, effective and safe. This study further explored the feasibility, effectiveness and safety of this detoxification procedure in a large group of patients...

Extraintestinal manifestations are common in inflammatory bowel disease; however, muscular involvement in Crohn disease is rarely reported. We present a case of a 26-year-old male with ileocolonic Crohn disease who developed sudden tenderness in both calves. Doppler ultrasound was negative for deep vein thrombosis. Magnetic resonance imaging of the gastrocnemius muscle showed high intensity signal in the muscle fibers, and muscle biopsy demonstrated nonspecific lymphocytic myositis. Other relevant laboratory results included normal antineutrophil cytoplasmic antibodies and creatine kinase as well as elevated C-reactive protein, erythrocyte sedimentation rate, and anti-Saccharomyces cerevisiae IgG titer...

Dating abuse is a prevalent and consequential public health problem. However, relatively few studies have compared methods of collecting self-report data on dating abuse perpetration. This study compares two data collection methods-(a) the Timeline Followback (TLFB) retrospective reporting method, which makes use of a written calendar to prompt respondents' recall, and (b) an interactive voice response (IVR) system, which is a prospective telephone-based database system that necessitates respondents calling in and entering data using their telephone keypads...

BACKGROUND: Due to the adverse effects of cemented hip arthroplasty, uncemented stems with hydroxyapatite (HA) coating reduces these risks and enhanced integration. The concept of an extensive HA coating for the fixation of a tapered femoral stem (Corail(®)) was introduced, which can achieve durable biological fixation and preserve normal periprosthetic bone activity. Here we describe the clinical and radiological outcome in patients with the Corail(®) stem. METHODS: 92 total hip replacements in 81 patients using the Corail(®) stem were followed-up...

Since the discovery of Clostridium difficile infection (CDI) in the 1970s, there has been an increase in the incidence, severity, and recurrence rate of the disease. We reviewed the recent CDI literature in PubMed published before February 28, 2016 that focused on advances in therapy. Despite a large number of studies describing methods for diagnosing the disease, there is currently no definitive test that identifies this infection with certainty, which complicates therapy. Recommended therapy for CDI includes oral metronidazole for mild cases and oral vancomycin or fidaxomicin for moderate to severe cases, each given for 10 to 14 days...

We build on the concept of hot intrusion embossing to develop a one-step fabrication method for thermoplastic microfluidic channels containing integrated three-dimensional features. This was accomplished with simple, rapid-to-fabricate imprint templates containing microcavities that locally control the intrusion of heated thermoplastic based on their cross-sectional geometries. The use of circular, rectangular and triangular cavity geometries was demonstrated for the purposes of forming posts, multi-focal length microlense arrays, walls, steps, tapered features and three-dimensional serpentine microchannels...

OBJECTIVE: We modified the fenestration approach for arytenoid adduction to make it easier to perform the surgery. The aim of this study was to evaluate the usefulness of our modifications, which included (1) use of an Alexis wound retractor (Applied Medical) to secure the surgical field through a small incision, and (2) use of a 12-mm, 1/2 R, insert-molded taper needle with 3-0 nylon suture to prevent damage to the arytenoid cartilage. STUDY DESIGN: This is a retrospective non-randomized observational cross-sectional study...

Structures with power law tapers exhibit the acoustic black hole (ABH) effect and can be used for vibration reduction. However, the design of ABHs for vibration reduction requires consideration of the underlying theory and its regions of validity. To address the competing nature of the best ABH design for vibration reduction and the underlying theoretical assumptions, a multi-objective approach is used to find the lowest frequency where both criteria are sufficiently met. The Pareto optimality curve is estimated for a range of ABH design parameters...

Full matrix arrays are excellent tools for 3-D ultrasound imaging, but the required number of active elements is too high to be individually controlled by an equal number of scanner channels. The number of active elements is significantly reduced by the sparse array techniques, but the position of the remaining elements must be carefully optimized. This issue is faced here by introducing novel energy functions in the simulated annealing (SA) algorithm. At each iteration step of the optimization process, one element is freely translated and the associated radiated pattern is simulated...

S Y Jauch-Matt, A W Miles, H S Gill
Modular hip implants are at risk of fretting-induced postoperative complications most likely initiated by micromotion between adjacent implant components. A stable fixation between ball head and stem-neck taper is critical to avoid excessive interface motions. Therefore, the aim of this study was to identify the effect of trunnion roughness and length on the modular taper strength under typical intraoperative assembly forces. Custom-made Titanium trunnions (standard/mini taper, smooth/grooved surface finish) were assembled with modular Cobalt-chromium heads by impaction with peak forces ranging from 2kN to 6kN...

BACKGROUND: In order to prevent postoperative dislocation due to prosthetic impingement as a result of total hip arthroplasty (THA), the combined anteversion (CA) theory, which combines the anteversion of the femoral stem and the acetabular socket, has been revised in recent years. Particularly, it is necessary to keep CA within the target zone. METHODS: The aim of this study was to investigate whether postoperative CA can be kept within the target zone while using the operative technique which prepares the socket first in cementless THA, by estimating the anteversion of the metaphyseal fit stem or the shorter, tapered wedge stem using preoperative 3-dimensional computerized planning, and by adjusting the anteversion of the socket using a navigation system that considers CA...

BACKGROUND: Endotracheal tube placement is necessary for the control of the airway in patients who are mechanically ventilated. However, prolonged duration of endotracheal tube placement contributes to the development of ventilator-associated pneumonias (VAPs). The aim of this study was to evaluate whether subglottic suctioning using TaperGuard EVAC tubes was effective in decreasing the frequency of VAP. METHODS: A total of 276 mechanically ventilated patients for more than 72 hours were randomly assigned to group E (EVAC tube) and group C (conventional tube)...

AIMS: Femoral impaction bone grafting was first developed in 1987 using morselised cancellous bone graft impacted into the femoral canal in combination with a cemented, tapered, polished stem. We describe the evolution of this technique and instrumentation since that time. PATIENTS AND METHODS: Between 1987 and 2005, 705 revision total hip arthroplasties (56 bilateral) were performed with femoral impaction grafting using a cemented femoral stem. All surviving patients were prospectively followed for a mean of 14...

Patients receiving long-term opioid therapy for chronic pain and interested in tapering their opioid dose were randomly assigned to a 22-week taper support intervention (psychiatric consultation, opioid dose tapering, and 18 weekly meetings with a physician assistant to explore motivation for tapering and learn pain self-management skills) or usual care (N=35). Assessments were conducted at baseline and 22 and 34 weeks after randomization. Using an intention-to-treat approach, we constructed linear regression models to compare groups at each follow-up...

The phaseless inverse scattering of optical or electromagnetic waves from unbounded fractally corrugated surfaces are taken into account. The main characteristics of this inverse scattering problem are that only the phaseless scattered field is measured and the incident field is a tapered wave. In the previous recent works of the authors about the inverse scattering of rough surfaces, the cases of the Dirichlet boundary condition were considered [Inverse Prob.32, 085002 (2016)INPEEY0266-561110.1088/0266-5611/32/8/085002; Inverse Probl...

The temperature distribution within extrusion nozzles of three low-cost desktop 3D printers is characterized using fiber Bragg gratings (FBGs) to assess their compatibility as micro-furnaces for optical fiber and taper production. These profiles show remarkably consistent distributions suitable for direct drawing of optical fiber. As proof of principle, coreless optical fibers (φ=30  μm) made from fluorinated acrylonitrile butadiene styrene (ABS) and polyethylene terephthalate glycol (PETG) are drawn...
