BACKGROUND Postpartum psychosis is a life-threatening psychiatric emergency, which often occurs without significant premorbid symptoms. Although many studies have postulated an involvement of the immune and endocrine systems in the onset of postpartum psychosis, the specific aetiological factors have remained unknown. AIMS To examine the hypothesis that autoimmune thyroid dysfunction may ...
CONTEXT The long-lived thyroid cell generates, for the synthesis of thyroid hormones, important amounts of H2O2 that are toxic in other cell types. This review analyzes the protection mechanisms of the cell and the pathological consequences of disorders of this system. EVIDENCE ACQUISITION The literature on H2O2 generation and disposal, thyroid hormone synthesis, and their control in the huma...
Transformation of rat thyroid cells with polyoma virus middle T antigen results in loss of the thyroid-differentiated phenotype, measured as the expression of the thyroglobulin (Tg), thyroperoxidase (TPO), and sodium/iodide symporter (NIS) genes. Among the transcription factors involved in the regulation of these genes, TTF-1 and TTF-2 were still detected at nearly wild-type levels, while a spe...
INTRODUCTION Recurrent abortion (RA) may be a consequence of aberrant expression of immunological factors during pregnancy. Although the relative importance of immunological factors in human reproduction remains controversial, substantial evidence suggests that autoantibodies contribute to reproductive failure. Production of such antibodies is under the control of cytokines; and leptin, besides...
We here analyzed the prevalence of extra-thyroidal malignancies (EM) in 6,386 female patients affected by different thyroid disease (TD). At first, an age-matched analysis of EM in all patients was performed. We then evaluated EM prevalence in four TD diagnostic categories: non-nodular TD (n = 2,159); solitary nodule (n = 905); multinodular TD (n = 2,871); differentiated thyroid cancers (n = 45...
We report the case of a 53-year-old woman with a personal history of chronic venous insufficiency and recurrent biliary colic who was seen after goiter was detected at during routine medical visit. A physical examination revealed diffuse grade 3 goiter associated with two to four bilateral hard nodules attached to deep planes. There were no adenopathies. No thyroid tenderness or other findings ...
OBJECTIVE The aim of this study was to determine thyroid hormone (TH) profile in postmenopausal patients with breast cancer (BC). SUBJECTS AND METHODS 12 CaM patients stages I or II, without interventions that could interfere with tumor progression were selected, as well as and a control group with 18 postmenopausal women without CaM. We measured serum anti-thyroperoxidase antibody (TPOAB), t...
