We report on the technique and results of percutaneous transhepatic biliary drainage (PTBD) in children with obstructive jaundice. Three patients aged 8 - 15 years were treated, two of them for a benign and one for a malignant stricture. Endoscopic treatment was not possible and all the PTBD procedures were done under general anaesthesia. One of the children was treated with external-internal drai
Objective: The course and the long-term outcome of 'refractory' secretory otitis media (SOM), defined as continuous SOM for more than 6 years, were studied in 52 young patients. They had during childhood been treated for bilateral SOM on average for 12 years (range 6 to 26 years). The mean interval between resolution of SOM and examination was 7 years. Methods: At follow up the patients' medical r
Complex surface reconstructions and surface oxides, in particular, often exhibit complicated atomic arrangements, which are difficult to resolve with traditional experimental methods, such as low energy electron diffraction (LEED), surface X-ray diffraction (SXRD) or scanning tunnelling microscopy (STM) alone. Therefore, ab initio density functional calculations are used as a supplement to the exp
Popular Abstract in Swedish De personer som ingår i undersökningen har gemensamt att de har erfarenheter av flera års avancerat narkotikamissbruk, varit drogfria i minst två år samt att de idag är socialt integrerade. Det faktum att de lyckats sluta missbruka narkotika och idag lever "vanliga liv" innebär att de tillhör en grupp som hitintills fått mycket liten uppmärksamhet av missbruksforskninge
Background: In patients requiring permanent pacing, preservation of intrinsic ventricular activation is preferred whenever possible. The Search AV+ (SAV+) algorithm in Medtronic EnPulse(TM) dual-chamber pacemakers can increase atrioventricular (AV) intervals to 320 ms in patients with intact or intermittent AV conduction. This prospective, multicenter study compared the percentage of ventricular p
Background: Assessing RNA quality is essential for gene expression analysis, as the inclusion of degraded samples may influence the interpretation of expression levels in relation to biological and/ or clinical parameters. RNA quality can be analyzed by agarose gel electrophoresis, UV spectrophotometer, or microcapillary electrophoresis traces, and can furthermore be evaluated using different meth
Ultrafast accelerator-based sources combined with synchronized femtosecond lasers are currently being developed. The method described here is intended as a jitter monitor at such facilities. We report on the possibility of extracting a time-offset signal between two different synchronized ultrashort light pulses. The method is based on sum-frequency generation in a nonlinear crystal. Aiming at ext
To broaden the AMS programme in Lund by including Al studies, a new injector has been installed and tested at the 3 MV Pelletron accelerator. Detailed optical calculations have been performed to obtain maximum mass and energy resolution. The design of the injector, the improvement in the resolution compared to the old injector, as well as preliminary tests with a Al-26-beam, are presented. By usin
Several risk factors for severe non-proliferative and proliferative retinopathy in type 1 diabetes mellitus have been proposed without explaining the rapid progression of retinopathy in some patients. Since GAD65 autoantibodies (GAD65Abs) are detected against glutamic acid decarboxylase (GAD), which is mainly expressed in islets and nervous tissue in type 1 diabetic patients, the aim of the presen
Popular AbstractAvhandlingen presenterar, från ett fenomenologiskt perspektiv, interaktionen mellan naturvetenskapens kunskap och annan kunskap, här kallad "vardagskunskap". Utgångspunkten i presentationen är människans existens. Två aspekter av denna lyfts fram som centrala - att människan är kroppsligt utsatt för, berörd av, något hon inte har full kontroll över, samt att hon alltid agerar utifrThe dissertation presents a phenomenological view on the interaction between science knowledge and prescientific knowledge. Drawing on Husserl, Merleau-Ponty and Lévinas the human bodily grounded existence is described, the central feature of this existence being its responsivity to the Other. This responsivity is presented as the starting point for the production of science knowledge, thus making
The Research Training Network “Women in European Universities” focuses on career opportunities of women in higher education in seven European countries (Austria, France, Germany, Poland, Spain, Sweden and the United Kingdom). Within the frame of this network different aspects of career perspectives of women – and also men – are investigated. In a first working step a context analysis was conducted
Popular Abstract in Swedish Ben, brosk och mjukvävnad (utgörs av den tvärstrimmiga muskulaturen, fettväv och fibrös bindväv, men också av det perifera nervsystemet) är vävnader av mesenkymalt eller neuroektodermalt ursprung. De flesta tumörer som uppstår i dessa vävnader är godartade och blir därför ofta inte föremål för behandling, vilket gör det svårt att uppskatta incidensen i befolkningen. EnlBone and soft tissue tumors (BSTT) constitute a heterogeneous group of neoplasms of mesenchymal and neuroectodermal origin. Although many BSTT are rare, it has become clear that BSTT are characterized by recurrent acquired chromosomal aberrations, and the general aim of this thesis have been to apply molecular genetic and molecular cytogenetic techniques to further characterize recurrent breakpoin
Objective Blood pressure variability (BPV) has been associated with risk of cardiovascular events in observational studies, independently of mean BP levels. In states with higher autonomic imbalance, such as in diabetes, the importance of BP variability may theoretically be even greater. We aimed to investigate the incremental value of BPV for prediction of cardiovascular and all-cause mortality i
Progressive retroversion of a cemented stem is predictive of early loosening and failure. We assessed the relationship between direct post-operative stem anteversion, measured with CT, and the resulting rotational stability, measured with repeated radiostereometric analysis over ten years. The study comprised 60 cemented total hip replacements using one of two types of matt collared stem with a ro
Timber structures and wooden element are in general affected by moisture and moisture variation in different ways. Their hygroscopic properties result in adsorption of water when wetted and in desorption when dried. Because the volume of wood is not constant but varies with the moisture content, uneven distribution of moisture will result in induced eigen-stresses because of internal restraint hyg
Dagens svenska våldtäktslagstiftning kräver att gärningsmannen använt sig av tvång eller utnyttjande för att straffansvar ska föreligga. Det har ifrågasatts om denna utformning av våldtäktslagstiftningen istället borde ersättas med en bestämmelse där samtycke ges en avgörande betydelse. Med en samtyckesbaserad våldtäktsreglering skulle den utslagsgivande faktorn för om ett brott har begåtts eller The Swedish rape legislation of today uses force as the delineator between non-criminal sex and criminal rape. It has been heavily disputed whether or not the force-based legislation ought to be replaced with the use of consent. In that case, consent or the lack of it would determine what is lawful or unlawful, regardless of any use of force. Despite the fact that the Swedish regulations on sexua
The objective of this paper was to show the potential additional insight that result from adding greenhouse gas (GHG) emissions to plant performance evaluation criteria, such as effluent quality (EQI) and operational cost (OCI) indices, when evaluating (plant-wide) control/operational strategies in wastewater treatment plants (WWTPs). The proposed GHG evaluation is based on a set of comprehensive
