Bexarotene associated dyslipidaemia and central hypothyroidism in a patient with Sézary syndrome

Alves M , Neves C , Azevedo F , Correia O , Carvalho-Braga D , Carvalho D

Background: Sézary syndrome (SS) is a more aggressive leukemic variant of cutaneous T-cell lymphoma (CTCL). Bexarotene (Targretin) is a synthetic rexinoid analogue designed for the treatment of advanced stages of cutaneous manifestations of CTLC. Bexarotene selectively suppresses thyrotropin secretion and up to 40% of patients develop reversible idiopatic central hypothyroidism. Severe mixed dyslipidemia may be present in up to 70%.Case report: Seve...

Hypoglycaemia following gastric banding

Oliveira A , Freitas P , Matos M , Vinha E , Braga D , Maia J , Bartosch C , Exposito M , Medina J

Introduction: Recently, noninsulinoma pancreatogenous hypoglycaemia syndrome (NIPHS) has been described following Roux-en-Y Gastric Bypass Surgery in morbidly obese patients. It has been proposed that hypoglycaemia might be a consequence of a failure to adaptively decrease insulin secretion after surgery. The authors present a case of a morbidly obese patient with severe hypoglycaemias beginning 3 months after gastric banding surgery.Case report: A 60-ye...

Prevalence of primary hypothyroidism in an obese population

Souto Selma , Mesquita Joana , Oliveira Ana , Freitas Paula , Correia Flora , Varela Ana , Carvalho Davide , Medina Jose Luis , Braga D

A positive association between thyrotropin (TSH) secretion and body-mass index (BMI) was previously reported. There are many studies concerning thyroid function in obesity, and some of them describe higher TSH levels in obese subjects.Evaluation of the hypothyroidism prevalence in a sample of obese women in their first obesity appointment at Hospital São João.Anthropometric variables and serum levels of TSH, free triiodot...

Cushing’s syndrome due to medullary thyroid carcinoma – a case report

Sousa A , Rodrigues E , Varela A , Vinha E , Braga D , Couto P , Lopes J , Cardoso-Oliveira M , Medina JL

Ectopic ACTH secretion due to malignant tumours is a rare cause of hypercortisolism. Induced metabolic disturbances are often serious and the management of such patients may be difficult. We report the case of a 50-yr-old man who had a sporadic medullary thyroid carcinoma (MTC) removed 2 years ago (Dec/2003). Calcitonin and CEA levels remained high postoperatively and a CT scan revealed liver metastases. In August 2005 he was referred to Endocrinology with symptoms of muscular...

Gilbert syndrome and diabetes: a perfect union?

Matos M J , Souto S B , Oliveira A I , Silva S , Vinha E , Freitas P , Queiros J , Braga D C , Carvalho D

Introduction: Gilbert syndrome is one of the most common inherited diseases, with a prevalence of 5–7%. It is caused by a mutation in UGT1A1 gene, which is in turn responsible for a deficiency in bilirubin glucuronidation. It courses with unconjugated hyperbilirubinemia, and jaundice may occur in adolescence, after fasting, exercise, or in menses, and also with certain drugs. Individuals with Gilbert syndrome seem to have a reduction in the prevalence of micro- and macrov...
