We report a rare case of cerebellar degeneration as a paraneoplastic syndrome in an 8-year-old boy with Hodgkin lymphoma that presented during first-line treatment. Antibodies against Purkinje cells (anti-Tr antibodies) were detected in the serum of the patient. After successful treatment of the lymphoma, the cerebellar symptoms resolved partially. Childhood presentation of paraneoplastic cerebellar degeneration is extremely rare, with only a few reports in the literature. For this reason, the description of all such cases contributes to the enrichment of the medical knowledge and will improve the diagnosis and the treatment of this complication.
In the presented work, a total of 60 bronze artefacts from the prehistoric settlement of Baley, Bulgaria were analyzed by means of laser-induced breakdown spectroscopy (LIBS) and X-ray fluorescence spectroscopy (XRF). The archaeological finds were excavated from three levels, with a time span from the 15th century BC to the first half of the 11th century BC. The obtained analytical information was used for quantitative estimation of the amount of tin, lead and arsenic, which determine the mechanical properties of the alloy and the manufacturing technology. Based on the estimated quantities of these elements, a chemometric statistical analysis (principal component analysis—PCA) was performed to classify and divide the samples into separate groups according to the production dating. The data obtained in this study can be used for comparison with the elemental content in deposits from other settlements of this period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
