Watchful waiting was recommended as an option for uncomplicated episodes of acute otitis media in Sweden in the year 2000. Concern was raised that these recommendations would lead to a higher incidence of acute mastoiditis. The aim of this study was to map the occurrence, treatment policy and the clinical course of mastoiditis before and after the new treatment recommendations were introduced. Inc

As we previously demonstrated, there is an adaptive increase in insulin secretion in insulin resistance in the model of high-fat fed female mice. Since it is assumed that islets also adapt to insulin resistance with β-cell expansion, we have now examined beta volume in this experimental model. Female C57BL/6JBomTac mice were therefore fed a high-fat diet (60% fat from lard) for three, six or twelv

We report a ten-year rate of survival of 96% for the cemented Freeman-Samuelson knee arthroplasty in patients from the Swedish Knee Registry and the Royal London Hospital with revision for aseptic loosening as the criterion for failure.

The central complement inhibitor factor I (FI) degrades activated complement factors C4b and C3b in the presence of cofactors such as C4b-binding protein, factor H, complement receptor 1 and membrane cofactor protein. FI is a serine protease composed of two chains; the light chain comprises the serine protease domain, while the heavy chain contains several domains: the FI and membrane attack compl

Histone deacetylase inhibitors (HDIs) and HAMLET (human alpha-lactalbumin made lethal to tumor cells) interact with histones, modify the structure of chromatin, and trigger tumor cell death. This study investigated how the combination of HDIs and HAMLET influences cell viability, histone acetylation, and DNA integrity. The pretreatment of tumor cells with HDIs was shown to enhance the lethal effec

In many control problems, e.g. in biology, time delays of the order of seconds or more play an important role. The present device is intended for simulations of such problems. Its accuracy (0·1 per cent) is of the same magnitude as that for most analogue computer components. It has been used in preliminary experiments (Fig. 5) to study biological rhythms. However, many differential equations with

BACKGROUND: The incidence of type 1 diabetes in Europe is increasing at a rate of about 3% per year and there is also an increasing incidence throughout the world. Type 1 diabetes is a complex disease caused by multiple genetic and environmental factors. Persistent organochlorine pollutants (POPs) have been suggested as a triggering factor for developing childhood type 1 diabetes. The aim of this

A signal–code construction is proposed that ensures a better relationship between decoding reliability and complexity than the classical scheme. The coder is partitioned into several “elementary” binary convolutional coders and the decoder is partitioned into several Viterbi decoders. The transmission of PSK-modulated signals is considered in more detail.

Behavioural and neuropsychological vulnerability have been associated with an increased risk of psychosis. We investigated whether certain clusters of premorbid behavioural and personality-related signs and symptoms were predictors of nonaffective and/or affective psychosis and schizophrenia, respectively, in a 50-year follow-up of an unselected general community population. Total population cohor

Male cancer survivors (MCS) are at risk of suffering from impaired fertility. Male fertility is dependant on sperm DNA quality. The Sperm Chromatin Structure Assay (SCSA) reflects the proportion of sperm with poor DNA, the DNA fragmentation index, DFI. A high DFI indicates reduced in vivo fertility and the need of ICSI (Intracytoplasmic sperm injection) to achieve pregnancy. A concern with ICSI, i

The aim was to investigate the construct validity and internal consistency of the Swedish version of the Consumer Emergency Care Satisfaction Scale. The sample comprised 157 persons from an emergency department and an observation ward. The results showed satisfactory reliability, and an explorative factor analysis revealed 3 factors: Caring, Teaching, and Clinical Competence. The Swedish version o

We have measured the absolute average photon flux, the spectral characteristics, and the time structure of x rays emitted from Ar clusters which were irradiated by a 100 fs laser with an intensity of 10(17) W/cm(2). The measured photon flux was 10(7) photons per shot in the K-alpha (at 3 keV) line in a 4 pi sr solid angle. The temporal structure was measured using a streak camera with a 10 ps time

The Transplantation Society, in collaboration with the Canadian Society of Transplantation, organized a forum on education on ODT for schools. The forum included participants from around the world, school boards, and representatives from different religions. Participants presented on their countries' experience in the area of education on ODT. Working groups discussed about technologies for educat

PURPOSE: Postoperative hypocalcaemia has been reported to be more common after total thyroidectomy (TT) for Graves' disease than after TT for benign atoxic multinodular goitre (MNG). The reasons for this potential association are not clear. In the present study, the frequency and risk factors of hypocalcaemia after TT for Graves' vs MNG were compared. METHODS: Between January 1999 and October 2009
