Effects of perinatal tributyltin exposure in Wistar rats on body parameters, insulin, leptin, milk composition and ultrastructure of the pancreatic islets in dams and offspring

Aparecida Miranda Rosiane , Vieira de Andrade Cherley Borba , Gaspar de Moura Egberto , Lisboa Patricia Cristina

Tributyltin (TBT) is a biocide organotin compound widely used as an antifouling in boat paints. This substance is a factor of contamination to water and food, especially marine fish. As an endocrine disruptor, TBT can interact with hormonal pathways and can induce gonadal dysfunction and glycemic dyshomeostasis; however, the effects caused by maternal exposure to TBT are scarce. Here, we investigate maternal exposure to low dose of TBT, considered safe, during pregnancy and la...

Chaves Catarina , Cunha Filipe , Rangel Ricardo , Coelho Daniela , Vieira Margarida , Garrido Susana , Martinho Mariana , Almeida Margarida

Introduction: Klinefelter syndrome (KS) represents the most common cause of hypergonadotrophic hypogonadism, with an estimated prevalence of 1:500 to 1:1000 men. This syndrome is characterized by the presence of an additional X chromosome. Eighty percent present with a 47,XXY karyotype and the remaining 20% present with a 47,XXY/46,XY mosaic or with multiple X chromosome aneuploidies, often with additional Y chromosomes. The presence of a 47,XXY/46,XX mosaic with male phenotyp...

Levothyroxine absorption test in the management of a patient with persistent hypothyroidism

Monteiro Joana , Ferreira Marta , Pires Miguel , Vieira Alexandra , Guelho Daniela , Pereira Teresa , Pinhal Fernanda , Fernandes Celio

Nonadherence to levothyroxine therapy is one cause of persistent hypothyroidism. To distinguish nonadherence from malabsorption, a levothyroxine absorption test (LAT) is sometimes required. The authors report a case of a 60-year-old female patient suffering from hypothyroidism resistant to oral levothyroxine (LT4) substitution after radioiodine therapy for Graves’ disease. Despite the continuous increases of LT4, over 10 years, to a maximum of 1 mg/d...

Simoes-Pereira Joana , Prazeres Susana , Macedo Daniel , Silva-Vieira Margarida , Marques Pedro , Pereira Maria Conceicao

Introduction: In our practice we’ve been following some oncologic survivors patients with low-low/normal levels of testosterone who are asymptomatic. Aims: to determine the levels of total (TT) and free testosterones (FT) and dihydrotestosterone (DHT) in healthy men, in order to find the reference intervals (RI) adjusted to our population and compare them with those provided by the kit-producers (KP).Methods: We collected blood samples from 125 heal...
