Hashimoto Encephalopathy Presenting as Schizophrenia-Like Disorder
No full textObjective: Hashimoto encephalopathy (HE) is associated with numerous neuropsychiatric symptoms and responds well to steroid therapy. In the past, only a few cases were reported to present with pure psychiatric syndromes. We describe a case of HE with presenting symptoms like that of schizophrenic patients. Methods: We describe a 73-year-old woman with a history of autoimmune Line thyroiditis. She had psychotic symptoms for 3 years that responded poorly to antipsychotic agents, and she was thus admitted in 2007. Results: The diagnosis of HE was made, although the patient presented neurologic symptoms and signs including abnormal electroencephalography, recent memory impairment, and executive function declination. The psychotic symptoms subsided completely in a few days after high-dose intravenous steroid therapy. Conclusions: The neuropsychiatric manifestation of HE can be similar to typical schizophrenia. Considering the effectiveness of steroid therapy for HE, we suggested HE as an important differential diagnosis for psychotic disorders, particularly for those patients of late onset, with abnormal electroencephalography, history of autoimmune thyroiditis, or poor response to conventional psychiatric treatment, so as to provide prompt and effective treatment for these patients
Hashimoto-Enzephalopathie – steroid-sensitive Enzephalopathie
No full textZusammenfassungDie Hashimoto-Enzephalopathie ist eine gut behandelbare, steroid-sensitive Enzephalopathie, die sich durch eine Assoziation mit einer Autoimmun-Thyreoiditis (Hashimoto-Thyreoiditis) auszeichnet. Bis jetzt wurden ca. 110 Fallbeschreibungen der Hashimoto-Enzephalopathie in allen Altersgruppen berichtet. Unklarheit besteht über die zugrunde liegenden pathogenetischen Mechanismen. Es können zwei charakteristische Verläufe mit im Vordergrund stehenden neurologischen und psychiatrischen Symptomen unterschieden werden: eine schleichend progrediente Variante und eine akute vaskulitische Form. Trotz unterschiedlicher klinischer Präsentation findet sich generell ein gutes Ansprechen auf eine immunsuppressive Therapie. Bei konsequenter Behandlung ist von einer guten Prognose auszugehen. Im Rahmen des aktuellen Überblicks gehen wir unter anderem auf die zur Zeit diskutierten Ätiologiemodelle, die diagnostischen Standards und die empfohlenen Therapieschemata ein. Differenzialdiagnostische und differenzialtherapeutische Konsequenzen werden diskutiert.</jats:p

Some considerations on Grim’s effective wave concept for restoring variations and its improvement
No full textNotions of independence related to the free group
No full textThe central limit problem for algebraic probability spaces associated with the Haagerup states on the free group with countably many generators leads to a new form of statistical independence in which the singleton condition is not satisfied. This circumstance allows us to obtain nonsymmetric distributions from the central limit theorems deduced from this notion of independence. In the particular case of the Haagerup states, the role of the Gaussian law is played by the Ullman distribution. The limit process is explicitly realized on the finite temperature Boltzmannian Fock space. The role of entangled ergodic theorems in the proof of the central limit theorems is discussed.

RAGE polymorphisms and oxidative stress levels in Hashimoto's thyroiditis
No full textBackground: Polymorphisms of the receptor for advanced glycation end products (RAGE) gene have been studied in various autoimmune disorders, but not in Hashimoto's thyroiditis. Also, increased oxidative stress has been described in patients with Hashimoto's thyroiditis. The aim of this study was to investigate the possible role of two common RAGE polymorphisms (−429T>C, −374T>A) in Hashimoto's thyroiditis; in parallel, we studied oxidative stress levels. Materials and methods: A total of 300 consecutive euthyroid women were examined and classified into three groups: Hashimoto's thyroiditis with treatment (n = 96), Hashimoto's thyroiditis without treatment (n = 109) and controls (n = 95). For a rough evaluation of oxidative stress, total lipid peroxide levels in serum were measured. The −429T>C AluI and −374T>A MfeI polymorphisms of RAGE were studied in genomic DNA. Results: Significant association of the RAGE system with Hashimoto's thyroiditis was found only with regard to the prevalence of the −429T>C, but not with −374T>A polymorphism. The levels of oxidative stress were significantly elevated in Hashimoto's thyroiditis patients under treatment. Further analysis demonstrated that an oxidative stress cut-off value of 590 μmol/L is associated with an increased risk of progression of Hashimoto's thyroiditis from euthyroidism to hypothyroidism; this risk is further increased in carriers of the RAGE −429T>C polymorphism. Conclusions: Our findings indicate that both examined risk factors may be implicated in the occurrence of Hashimoto's thyroiditis, but this covers only a fraction of the pathophysiology of the disease. © 2017 Stichting European Society for Clinical Investigation Journal Foundatio
