BackgroundFrontotemporal lobar degeneration with ubiquitin and TDP-43 positive neuronal inclusions represents a novel entity (FTLD-TDP) that may be associated with motor neuron disease (FTLD-MND); involvement of extrapyramidal and other systems has also been reported.Case presentationWe present three cases with similar clinical symptoms, including Parkinsonism, supranuclear gaze palsy, visuospatial impairment and a behavioral variant of frontotemporal dementia, associated with either clinically possible or definite MND. Neuropathological examination revealed hallmarks of FTLD-TDP with major involvement of subcortical and, in particular, mesencephalic structures. These cases differed in onset and progression of clinical manifestations as well as distribution of histopathological changes in the brain and spinal cord. Two cases were sporadic, whereas the third case had a pathological variation in the progranulin gene 102 delC.ConclusionsAssociation of a "progressive supranuclear palsy-like" syndrome with marked visuospatial impairment, motor neuron disease and early behavioral disturbances may represent a clinically distinct phenotype of FTLD-TDP. Our observations further support the concept that TDP-43 proteinopathies represent a spectrum of disorders, where preferential localization of pathogenetic inclusions and neuronal cell loss defines clinical phenotypes ranging from frontotemporal dementia with or without motor neuron disease, to corticobasal syndrome and to a progressive supranuclear palsy-like syndrome.
The increased AIP and hs-CRP concentration after 9 months of hormonal contraception demonstrate that contraceptive-induced dyslipidemia has a proatherogenic nature, even when the TC/HDL-C and the apoB/apoA1 ratios are unchanged.
Aim: We designed this study to assess the effect of breastfeeding and its duration on acute otitis media (AOM) in children of our geographical region. Our main aim was to determine the period of breastfeeding, necessary to achieve optimal preventive results against AOM. Methods: The children that, according to the questionnaire, had suffered AOM infections in the past were used as the study group with the rest of the children used as control. The duration of breastfeeding was divided into months and the odds ratios for the occurrence of AOM were calculated for the children breastfed for more than or equal to a certain period, compared to the children breastfed for less than that period. This was repeated for each month separately and the results plotted on a graph of the confidence interval (CI) for the odds ratio values, against months of breastfeeding. Results: The results of our study show that breastfeeding for a period of up to 11 months can play a significant preventive role against AOM (odds ratio and lower 90% CI >1). Breastfeeding for longer periods of time is also beneficial, with breastfeeding up to 18 months being associated with some preventive effect against the disease (odds ratio >1), but the reduction in the incidence of AOM is not statistically significant after the 11th month. Furthermore, there are marked differences in the importance of breastfeeding during the first 11 months, with a vital protective effect during the first 4 months of life which, however, drops by the 5th month and then rises again from the beginning of the 6th to the end of the 8th month. The protective effect then drops once more, although it remains positive and statistically significant until the 11th month of life and positive, but not statistically significant, until the 18th. Conclusion: Our study has revealed that for an optimal preventive effect to be achieved, the child should be breastfed for at least the first 11 months of its life. Continuing after this for up to the 18th month shows some preventive effect, which however is not statistically significant. Our results support the hypothesis that the importance of breastfeeding varies with the development of the child, its changing environment and to the new immunological challenges this brings.
Interindividual differences between the parameter values have been identified. This could be helpful in methodological conception of preventive training programmes for patients suffering from cardiovascular disease. The mutual connection between the parameter values and age groups does not relate only to a safer training intensity determination, but also to a more precisely targeted application of different training modalities in order to achieve an optimal final training effect.
The results show a relatively high consumption of alcohol in the examined group. The recommended weekly limits were exceeded by only a small portion, but that consumption had a binge character. Conversion into a form allowing comparison with conventional national statistics shows a significantly lower consumption than these reported statements. Overall, men consume significantly more alcohol than women.
A series of macroporous crosslinked copolymers of 2-hydroxyethyl methacrylate (HEMA) with methacrylic acid (MA) was prepared in the presence of fractionated particles of sodium chloride. The hydrogels were characterized by the number of pores in unit volume, the pore size, the water content in pores and diffusion parameters. The structure of the hydrogels was followed by confocal and scanning electron microscopy.Macroporous hydrogels find application as biocompatible implants in tissues, such as in the central nervous system 1,2 or as substrates in cellular and tissue engineering 3-7 . Porosity is usually achieved by one of four basic methods:1. Crosslinking polymerization in the presence of substances that are solvents for the monomers, but precipitants for the formed polymer 1-8 .2. Crosslinking polymerization in the presence of soluble substances (sugars, salts) which are washed out from the hydrogel after polymerisation 3-6 .3. By crosslinking polymerization in the presence of substances liberating gases which remain in the resulting hydrogel 9 .4. By frost sublimation of the hydrogel swollen in water 10,11 .
Gerstmann-Sträussler-Scheinker syndrome is a rare autosomal dominant disease caused by a mutation in the prion gene, usually manifesting as progressive ataxia with late cognitive decline. A 44-year-old woman with a positive family history developed early personality and behavior changes, followed by paresthesias and ataxia, later associated with memory problems, pyramidal signs, anosognosia and very late myoclonus, spasticity, and severe dysexecutive impairment. Magnetic resonance showed caudate, mesio-frontal, and insular hyper-intensities, electroencephalography revealed generalized triphasic periodic complexes. A pathogenic P102L mutation in the prion gene was detected. Our case differed from classical Gerstmann-Sträussler-Scheinker syndrome by rapid progression, severe dementia, abnormal electroencephalography and magnetic resonance findings, which were highly suggestive of familial Creutzfeldt-Jakob disease.
