The vast majority of thyroid cancers are solid. Predominantly cystic tumors occur in <3% cases. Guidelines report as US characteristics consistently associated with a higher risk of malignancy eccentric position of the solid component, acute angle interface and microcalcifications and as less robustly associated lobulated margins and increased vascularity of the solid portion. We reviewed the US characteristics of predominantly cystic papillary carcinomas confirmed on hist...

Very high urinary free cortisol levels in patients treated with tuberculostatics

Roque Catarina , Osorio Ana Sofia , Fonseca Ricardo

Introduction: Pharmacologically induced false positive results in urinary free cortisol levels (UFCL) have been ascribed to 11βHSD-2 inhibition or direct interference on HPLC. Few drugs have been implicated by mechanisms not yet confirmed.Case Reports: We report 3 patients with active pulmonary tuberculosis (TB) and very high UFCL, 2-6× above the upper limit of reference [mean levels 3411 μg/24 h (RR 167-827)]. The 2 males and the woman ag...

One of this rare forms is MODY 5, the result of a mutation on the hepatocyte nuclear factor 1 beta (HNF-1B) gene that associates with genitourinary and pancreatic malformations/dysfunction.Case report: A 24-year-old female was referred to the Endocrinology clinic due to hyperglycaemia identified on pr...

Treatment of toxic multinodular goiter with 131 radioactive iodine – effects in volume reduction, thyroid function and autoimmunity

Roque Catarina , Sousa Santos Francisco , Pilli Tania , Pacini Furio

Abstract: Radioiodine is a definite treatment option for toxic goiter. We have evaluated volume reduction, function and autoimmunity outcomes with a 15 mCi fixed regimen. Patients with at least one US evaluation before and after Iodine-131 therapy and with at least one year of follow-up were included. TSH, free-T4, antibodies and goiter volume before and yearly after Iodine-131 treatment were analysed for the length of the entire follow-up. The total 151 patients, 72.6% female...

Erectile Dysfunction – The hidden sickness we don’t seek

Roque Catarina , Capitao Ricardo , Ferrinho Catia , Duarte Sequeira , Vasconcelos Carlos

Introduction: Erectile dysfunction (ED) is highly prevalent and negatively impacts the patient’s and the partner’s quality of life. It is a well-established red flag for ongoing neuro-vascular disease and a predictor of coronary, cerebral and peripheral arterial disease (PAD). Our aim was to document how often do clinicians investigate ED and use it as a predictor of neuro-vascular pathology to trigger a thorough revision of cardiovascular risk factors (CVRF). This a...
