Alcohol consumption in elderly people across European countries: Results from the food in later life project

The aim of this paper is to identify social and cultural aspects of alcohol consumption in a sample of older people living in their own homes, in eight different European countries. We explore several aspects of alcohol consumption, establishing comparisons between genders, age groups and living circumstances. The phenomenon of alcohol consumption within these countries and cultures is compared in order to gain a better understanding of similarities and differences.

Incidence of juvenile idiopathic arthritis in the Nordic countries. A population based study with special reference to the validity of the ILAR and EULAR criteria

OBJECTIVE: To find the incidence of juvenile arthritis according to the ILAR and EULAR criteria within defined areas in the Nordic countries, and to study the validity of the ILAR and EULAR criteria from this perspective. METHOD: A longitudinal, prospective, population based study with patients enrolled according to the ILAR and EULAR criteria. Twenty doctors in Iceland, Norway, Sweden, Denmark, and Finland collected data from the incidence cases within their catchment areas over a period of 1.5 years, beginning July 1, 1997. Clinical and serological data from the first year of the disease were collected. RESULTS: In the whole group of 315 patients, the incidence rate was 15 per 100,000 children/year (95% CI 13-17) according to the ILAR criteria, varying from 7 (1-13) in Iceland, 19 (7-31) and 23 (10-36) from 2 different regions in Norway, and 9 (5-12) and 16 (9-23) from 2 different areas in Denmark, to 15 (12-18) in Sweden and 21/100,000/year (15-26) in the Helsinki region in Finland. An early peak in distribution for age of onset was found in girls but not in boys. The number of antinuclear antibody (ANA) positive children in the whole group, made up of children who had undergone at least one analyzed ANA test, was 123/315 (39%). Girls were ANA positive in 83/197 (42%) and boys in 40/118 (34%). Uveitis developed in 27/315 (8.6%) children during the first 6 months of the disease. CONCLUSION: Incidence rates of juvenile arthritis for areas within the Nordic countries were in accord with previous data. The ILAR criteria present slightly higher incidence rates, with a shorter disease duration for inclusion, compared to the EULAR criteria. Patients in one subgroup in either of the criteria sets do not necessarily belong to the expected subgroup in the other set of criteria; e.g., for juvenile ankylosing spondylitis (EULAR) and enthesitis related arthritis (ILAR). Our epidemiological findings are a reminder to be aware of possible new subgroups in children with juvenile arthritis.     

Measuring visual field progression in the Early Manifest Glaucoma Trial

AIMS: The Early Manifest Glaucoma Trial (EMGT) (316 eligible eyes) has used a new set of criteria to define visual field progression in glaucoma. This paper provides estimates of the amount of visual field worsening required to reach the EMGT definition of definite perimetric progression. METHODS: In the 148 eyes that reached definite progression, we first determined changes between baseline and the time of definite EMGT progression, both for mean deviation (MD) and for number of highly (p < 0.5%) significantly depressed test points in pattern deviation probability maps. Second, we studied whether such changes depended on baseline MD, intraocular pressure (IOP), age and time to progression, all of which are factors that affect the rate of field progression. RESULTS: In eyes reaching progression, the mean change in MD from baseline was -1.93 dB (SE +/- 0.20) and the mean change in number of significant points was +4.85 (SE +/- 0.35). These changes did not show linear dependency on baseline MD, IOP or time to progression. CONCLUSIONS: The average amount of field deterioration needed to reach EMGT visual field progression has been measured and expressed in more conventional units (i.e. a loss of about - 2dB in MD and an increase in about five highly significant points). These estimates will facilitate the clinical interpretation of the results of EMGT.     

Uveal melanoma survival in Sweden from 1960 to 1998

PURPOSE: To investigate the crude and relative survival rates in patients with uveal melanoma in Sweden during the period from 1960 to 1998. METHODS: A population-based national survey revealed 2997 cases of uveal melanoma in the Swedish Cancer Registry. The survival rates were calculated by the Hakulinen life-table method, using relative survival as an estimate for deaths due to uveal melanoma. The excess mortality rates were calculated with confidence intervals for the first 15 years after diagnosis. Multivariate regression analysis was undertaken to evaluate the influence of gender, age, and calendar period on relative survival the first 5 years after diagnosis. The underlying causes of deaths in the patients with uveal melanoma, as found in the Cause of Death Registry were also investigated. RESULTS: Up to December 31, 1998, 2003 patients had died. The 5-year crude survival rate was 60.3% and the relative survival 70.1%. After 10 years, the rates were 42.5% and 59.4%, respectively. Significant excess mortality existed up to 5.5 years after diagnosis. In the multivariate model, younger age (P < 0.001) and later calendar period (P = 0.002), but not gender (P = 0.117), were associated with better relative survival. Deaths due to uveal melanoma were misclassified in the Cause of Death Registry in more than half of the cases. CONCLUSIONS: This study, covering more than 95% of the uveal melanoma cases in the Swedish population revealed an improvement in relative survival rates for patients with uveal melanoma over time and a significant excess mortality up to 5.5 years after diagnosis.     

Distribution of glucocorticoid receptor alpha and beta subtypes in the idiopathic inflammatory myopathies

In contrast with dermatomyositis and polymyositis, inclusion body myositis is unresponsive to glucocorticoid treatment. Glucocorticoid action is mediated through an active glucocorticoid receptor-alpha and negatively regulated by another glucocorticoid receptor isoform. In several autoimmune diseases glucocorticoid receptor-beta up-regulation is involved in glucocorticoid resistance. We studied glucocorticoid receptor distribution in normal and inflammatory myopathy muscle and investigated whether differences in glucocorticoid receptor-alpha and glucocorticoid receptor-beta protein expression are involved in the differential glucocorticoid sensitivity in inclusion body myositis versus polymyositis. Multistep immunofluorescence and Western blotting on fractionated cytoplasmic or nuclear muscle samples were used. Glucocorticoid receptor-alpha was the predominant receptor subtype in muscle and occurred abundantly in myonuclei of control and diseased muscle alike. Glucocorticoid receptor-beta was constitutively expressed on a subset of endothelial cells. No differences between dermatomyositis and the other idiopathic inflammatory myopathies were observed. Increased nuclear glucocorticoid receptor that has dissociated from heat shock protein 90 was found in glucocorticoid treated subjects. Glucocorticoid receptor-alpha and -beta isoform levels were unaltered in muscle tissues from control subjects that had received glucocorticoid treatment prior to biopsy. No differences in relative glucocorticoid receptor-alpha and glucocorticoid receptor-beta protein expression were seen in inclusion body myositis versus polymyositis specimens. Our study indicates that the different glucocorticoid sensitivity in the idiopathic inflammatory myopathies is not related to up- or down-regulation of a given glucocorticoid receptor isoform at the protein level.     

Stenting of the biliary tract in children.

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 drainage, and the two others by insertion of a plastic endoprosthesis. There were no immediate complications. The PTBD had a good palliative effect in two cases, and in one case surgical treatment was necessary. We conclude that PTBD is a safe modality and that it can be used in children for the relief of obstructive jaundice.     

A pseudo-outbreak of pharyngeal gonorrhoea related to a false-positive PCR-result

Nucleic acid amplification tests, including the polymerase chain reaction (PCR), are sensitive and specific tests that are often used for diagnosing sexually transmitted diseases (STDs). A pseudo-outbreak of pharyngeal gonorrhoea in a group of prostitutes turned out to have been caused by false-positive test results due to commensal oropharyngeal Neisseria species. Specific molecular tests may yield erroneous results. When the results of an STD study have major consequences at a legal or social level, it is advisable, in consultation with a medical microbiologist, to take a sample for culture or to carry out a second molecular test aimed at a different part of the bacterial genome.     

The effect of short-course gentamicin therapy on kidney function in patients with bacteraemia—a retrospective cohort study

The nephrotoxic potential of aminoglycosides is primarily correlated to the duration of therapy. However, there are discrepancies between previous studies regarding the effect of short course treatment. The aim of this study was to compare renal function, renal recovery and mortality in a large cohort of patients with bacteraemia, who were empirically treated with regimens with and without a short course (≤?3 days) of once daily dosing of gentamicin. This was a retrospective propensity score-matched cohort study based on all patients with bacteraemia in a Danish hospital in the period 2010–2013. We included 702 patients who received gentamicin, and 702 who did not receive gentamicin. To determine the impact of gentamicin on renal function, we used a modified version of the Kidney Disease: Improving Global Outcomes (KDIGO) criteria for acute kidney injury (AKI), and the resulting data were analyzed by logistic regression. We used Cox regression analysis to compare the adjusted mortality rates between the two groups. According to the KDIGO criteria, we found no significant difference in the occurrence of AKI between the two groups (odds ratio (OR) 0.90 (95% CI 0.68–1.20)). We found that recovery of renal function was similar in the two groups, OR 1.00 (95% CI 0.63–1.60). The hazard ratio for 90-day all-cause mortality was 1.02 (95% CI 0.84–1.25). Short-course empirical gentamicin treatment of patients with bacteraemia was not associated with an increased incidence of AKI nor all-cause mortality in this study, and we observed similar reversibility of renal function.     

Performance of time‐domain and spectral‐domain Optical Coherence Tomography for glaucoma screening

Purpose: To investigate the measures of validity for selective or population screening of the time‐domain Stratus and the spectral‐domain Cirrus Optical Coherence Tomography (OCT) imaging techniques in a population‐based sample and in clinical glaucoma patients at different stages of glaucoma. Patients and methods: A random sample of 307 subjects living in two rural areas in southern Sweden, and a random sample of 394 clinical glaucoma patients were selected. A large battery of examinations, including Stratus and Cirrus OCT was performed. OCT retinal nerve fibre layer (RNFL) thickness analyses for average thickness, quadrant and clock‐hour sectors were compared with normative significance limits available in the instruments. Results: The population‐based sample included 129 healthy and nine glaucoma subjects, and the sample of clinical glaucoma patients included 138 patients. Specificity and positive predictive values were generally better with Stratus than for Cirrus, and sensitivity was generally better with Cirrus. With the average RNFL thickness parameter, Stratus reached 100% specificity and a positive predictive value of 100% and 68% sensitivity in the whole group of the clinical glaucoma patients, but sensitivity was only 28% among the earliest stage glaucoma patients. Sensitivity increased considerably when relying on the quadrant sector parameter, while specificity decreased only marginally. Conclusion: Stratus, with high specificity and positive predictive values, seemed to be best of choice for screening purposes, while Cirrus, with high sensitivity, was the better choice for early detection.
