Introduction and hypothesis
Lichen sclerosus (LS) is thought to be primarily a disease of postmenopausal women. Little is reported about lower urinary tract symptoms (LUTS) in association with LS. The aims of this study were to evaluate the odds of having LS-associated LUTS and to identify the predominant type of LS-associated bladder dysfunction.Methods
This was a cross-sectional study with two cohorts investigating the association between LS and LUTS and the predominant type of LS-associated bladder dysfunction.Results
The odds of LUTS in women with LS were more than four times higher than in women without LS (OR 4.5, 95% CI 2.6–8.0; p < 0.0001). There was no significant difference in the occurrence of LUTS between women who experienced the first LS symptoms before and after the age of 50 years (36% and 53%, respectively, p = 0.14), or in the occurrence of the different types of LUTS between women with and without LS (p = 0.3). The most common type of LUTS was overactive bladder (OAB) in both women with LS (67.3%) and without LS (60%). The most prevalent type of LS-associated LUTS was OAB.Conclusions
The odds of developing LUTS (self-reported) are four times higher in women with LS than in those without. The predominant type of LUTS in women with and without LS is OAB.Background
Long-term effect of enteral tube feeding (ETF) in cystic fibrosis (CF) remains equivocal.Methods
A Belgian CF registry based, retrospective, longitudinal study, evaluated the pre- and post- ETF (n?=?113) clinical evolution and compared each patient with 2 age, gender, pancreatic status and genotype class-matched controls.Results
At baseline ETF had a worse BMI z-score (p?<?0.0001) and FEV1% (p?<?0.0001) compared to controls. Patients eventually receiving ETF, had already a significant worse nutritional status and pulmonary function at first entry in the registry. Both parameters displayed a significant decline before ETF-introduction. ETF had more hospitalization and intravenous antibiotic (IVAB) treatment days (p?<?0.0001). After ETF introduction hospitalizations and IVAB decreased significantly. After ETF-introduction BMI z-score recuperated towards the original curve before the decline, but remained below the controls. Starting ETF had no effect on rate of height gain in children. The pre-index FEV1 decline (?1.52%/year (p?=?0.002)) stabilized to +0.39%/year afterwards. Controls displayed decline of ?0.48%/year (p?<?0.0001).Conclusion
ETF introduction improved BMI z-score and stabilized FEV1, associated with less hospitalizations and IVAB treatments. Higher mortality and transplantation in the ETF cases, leading to drop-outs, made determination of the effect size difficult. 相似文献Background
Hereditary hemochromatosis is the most frequent, identified, genetic disorder in Caucasians affecting about 1 in 1000 people of Northern European ancestry, where the associated genetic defect (homozygosity for the p.Cys282Tyr polymorphism in the HFE gene) has a prevalence of approximately 1:200. The disorder is characterized by excess iron stores in the body. Due to the incomplete disease penetrance of disease-associated genotype, genetic testing and accurate quantification of hepatic iron content by histological grading of stainable iron, quantitative chemical determination of iron, or imaging procedures are important in the evaluation and staging of hereditary hemochromatosis.Methods
We here established novel laser ablation inductively coupled plasma mass spectrometry protocols for hepatic metal bio-imaging for diagnosis of iron overload.Results
We demonstrate that these protocols are a significant asset in the diagnosis of iron overload allowing iron measurements and simultaneous determination of various other metals and metalloids with high sensitivity, spatial resolution, and quantification ability.Conclusions
The simultaneous measurement of various metals and metalloids offers unique opportunities for deeper understanding of metal imbalances. Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is a highly powerful and sensitive technique for the analysis of a variety of solid samples with high spatial resolution. We conclude that this method is an important add-on to routine diagnosis of iron overload and associated hepatic metal dysbalances resulting thereof.The aims of this study were to evaluate the diagnostic accuracy of the dual imaging method combining cardiac iodine-123-metaiodobenzylguanidine single-photon emission computed tomography combined with low-dose chest computed tomography compared to routine cardiac scintigraphy, and assess regional differences in tracer distribution and the relationships between imaging and autonomic function in Parkinson’s disease and multiple system atrophy.
MethodsA prospective study including 19 Parkinson’s disease and 12 multiple system atrophy patients was performed. Patients underwent clinical evaluation, iodine-123-metaiodobenzylguanidine single-photon emission computed tomography combined with chest computed tomography, planar scintigraphy, and cardiovascular autonomic function tests.
ResultsCo-registration of single-photon emission computed tomography and chest computed tomography resulted in three groups with distinct patterns of tracer uptake: homogeneous, non-homogeneously reduced and absent. There was a significant difference in group allocation among patients with multiple system atrophy and Parkinson’s disease (p?=?0.001). Most multiple system atrophy patients showed homogeneous uptake, and the majority of Parkinson’s disease patients showed absent cardiac tracer uptake. We identified a pattern of heterogeneous cardiac tracer uptake in both diseases with reductions in the apex and the lateral myocardial wall. Sympathetic dysfunction reflected by a missing blood pressure overshoot during Valsalva manoeuvre correlated with cardiac tracer distribution in Parkinson’s disease patients (p?<?0.001).
ConclusionsThe diagnostic accuracy of the dual imaging method and routine cardiac scintigraphy were similar. Anatomical tracer allocation provided by the dual imaging method of cardiac iodine-123-metaiodobenzylguanidine single-photon emission computed tomography and chest computed tomography identified a heterogeneous subgroup of Parkinson’s disease and multiple system atrophy patients with reduced cardiac tracer uptake in the apex and the lateral wall. Sympathetic dysfunction correlated with cardiac imaging in Parkinson’s disease patients.
