Two- and three-dimensional saline contrast sonohysterography: interobserver agreement, agreement with hysteroscopy and diagnosis of endometrial malignancy.

OBJECTIVES: The aims of our study were to compare the interobserver reproducibility of two-dimensional (2D) and three-dimensional (3D) saline contrast sonohysterography (SCSH) and agreement of these techniques with hysteroscopy, and to determine which SCSH findings best discriminate between benign and malignant endometrium. METHODS: Consecutive women with postmenopausal bleeding and endometrial th

Management of patients with Arrhythmogenic Right Ventricular Cardiomyopathy in the Nordic countries.

Abstract> Objectives. Diagnostics of patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) are complex, and based on the 2010 Task Force document including different diagnostic modalities. However, recommendations for clinical management and follow-up of patients with ARVC and their relatives are sparse. This paper aims to give a practical overview of management strategies, risk str

Intrajejunal Levodopa Versus Conventional Therapy in Parkinson Disease: Motor and Nonmotor Effects.

ABSTRACT: Seventeen patients with advanced Parkinson disease (PD) were treated with intrajejunal L-dopa infusion (IJL) and compared with a matched group of 9 patients (termed comparator [C]) not given IJL because of funding restriction by primary care trusts (PCTs) in the UK, although considered to be clinically eligible for IJL. Assessments were baseline and follow-up (6 months) with Hoehn and Ya

Visibility of microcalcification clusters and masses in breast tomosynthesis image volumes and digital mammography: A 4AFC human observer study.

Purpose: To investigate the visibility of simulated lesions in digital breast tomosynthesis (BT) image volumes compared with 2D digital mammography (DM). Methods: Simulated lesions (masses and microcalcifications) were added to images of the same women acquired on a DM system (Mammomat Novation, Siemens) and a BT prototype. The same beam quality was used for the DM and BT acquisitions. The tota

Tightly Coupled Positioning and Multipath Radio Channel Tracking

Radio based localization is an active research topic with a wide range of applications. In this paper, we focus on localization of a radio receiver equipped with an inertial measurement unit. The localization is performed while simultaneously constructing a map of the small scale fading pattern in the local radio environment. The map in our case is a ray-trace-based multipath channel model. This s

Wallenbergs fysikpris: Pröva själv en av teoriuppgifterna

I oktober 2012 lanserades ”Projekt Helix” på Liseberg – en ny stor berg- och dalbana inför vårpremiären 2014. Den klassiska Lisebergbanan får nu sällskap på berget av en något längre bana, med många nya element och exempel på ny teknik. Bland annat innehåller den två accelerationszo- ner, där tåget tillförs energi med linjära synkronmotorer (LSM). Efter den andra accelerationszonen, där tåget får

A self-consistent optical potential theory for atoms in solids

We develop an approximation for the optical potential in a solid, valid at intermediate energies, i.e. energies greater than 50 eV. The present approximation for the optical potential builds on the GW-expression. We separate the RPA polarization propagator into a core electron and a valence electron, and can then achieve a corresponding separation of the optical potential. We apply this method to

Long term survival in women with borderline ovarian tumors: a population-based survey of borderline ovarian tumors in Sweden 1960-2007.

Evaluation of incidence and survival of patients with borderline ovarian tumors in Sweden MATERIAL AND METHODS: All women diagnosed with borderline ovarian tumor in the Swedish Cancer Register 1960-2007 (n=6,252) combined with follow-up in the Swedish Death Registry to 1 July 2009 were included. Estimation of age-standardized relative survival rate according to time periods for diagnosis RESULTS:
