Pseudo malabsorption of levothyroxine

Alves M. , Rodrigues D. , Baptista C. , Ribeiro C. , Oliveira P. , Vieira A. , Gouveia S. , Saraiva J. , Moreno C. , Bastos M. , Carvalheiro M.

Background: Therapy with levothyroxine (L-T4) is essential in hypothyroidism treatment. The marked elevation of thyrotropin (TSH) in patients treated with appropriate doses of L-T4 is rare and can result from malabsorption, drug interaction or poor adherence. The non-adherence, omitted by the patient, is called pseudo malabsorption.Clinical report: ACCS, female, 30 years old, hospitalized for persistent...

How differentiated can a poorly differentiated thyroid cancer be? A rare case presenting with hyperthyroidism and secondary adrenal insufficiency

Melo M , Carrilho F , Ribeiro C , Carvalheiro M

Introduction: Poorly differentiated thyroid cancers are usually aggressive tumors that lack many of the characteristics of differentiated thyroid tissue, including the ability to uptake and process iodine.Case report: A 75-year-old male presented with weight loss, tiredness, asthenia, tremor, increased perspiration, tachycardia and bone pain in several locations. A hard and fixed thyroid nodule was palpable in the left lobe (FNA-«follicular tumor&#1...

Evaluation of clinical presentation, treatment approach and outcome of a cohort of patients with acromegaly: a single centre experience

Gouveia S. , Paiva I. , Ribeiro C. , Vieira A. , Alves M. , Saraiva J. , Moreno C. , Carvalheiro M.

Introduction: Acromegaly is a rare disease with a high morbidity and mortality rate.Our aim was to characterise the population with acromegaly that is currently under supervision at our Department.Materials and methods: We included 104 patients with acromegaly (mean age at the diagnosis 44.0±13.0; with 71.2% females).The referred population was analysed on what concerns disease’s duration, clinical ...

X-linked adrenoleukodystrophy: an intersection between Endocrinology and Neurology

Gouveia S , Gomes L , Ribeiro C , Vieira A , Alves M , Saraiva J , Carvalheiro M

Introduction: X-linked adrenoleukodystrophy (X-ALD) is an important cause of primary adrenocortical insufficiency (PAI) in men. It’s characterized by impairment in peroxisomal degradation of very-long-chain-fatty-acids (VLCFA), leading to its accumulation on central nervous system, adrenal cortex and testes.Adrenomyeloneuropathy, the most common phenotype of X-ALD, coexists with PAI in up to 70% cases.Case report: A 28-year-ol...

Recombinant tsh-stimulated thyroglobulin measurements in patients with differentiated thyroid carcinoma with basal thyroglobulin <1 ng/ml

Vieira A , Carrilho F , Ribeiro C , Melo M , Alves M , Gouveia S , Saraiva J , Carvalheiro M

Introduction: A value of thyroglobulin (Tg) undetectable under treatment with levothyroxine (LT) does not exclude residual/metastatic disease; this can be found in 18–35% of patients after recombinant TSH-stimulated Tg (sTg) measurements.Objective: Evaluating the role of recombinant TSH-stimulated thyroglobulin (sTg) measurements in patients with differentiated thyroid carcinoma, treated with suppressive LT doses, with basal Tg (bTG)<1 ng/ml.</p...

Invasive prolactinoma with multiple recurrences: pituitary atypical adenoma or pituitary carcinoma? Report of a case

Gomes L , Paiva I , Ribeiro C , Gomes F , Rito M , Rebelo O , Carvalheiro M

Background: Invasive pituitary tumors may behaviour like some pituitary carcinomas. Although invasiveness is not indicative of malignancy, it probably puts the patient at higher risk of developing a pituitary carcinoma. These are very rare and the diagnosis requires evidence of metastatic disease, either cerebrospinal or extracranial. Although de novo development cannot be excluded they usually present as typical pituitary adenomas, which reveal their malignant characte...

Considering familial benign hypocalciuric hypercalcemia on differential diagnosis of primary hyperparathyroidism

Gouveia S. , Paiva S. , Gomes L. , Ribeiro C. , Vieira A. , Alves M. , Saraiva J. , Moreno C. , Carvalheiro M.

Introduction: Primary hyperparathyroidism is the most common cause for hypercalcemia. Familial benign hypocalciuric hypercalcemia (FBHH) is an unusual autosomal dominant disease. The mutation in the calcium sensing receptor (CaSR) determines a shift to the right in the calcemia set-point that inhibits PTH secretion. Generally asymptomatic, these patients present with mild hypercalcemia and hypophosphatemia, normal or slightly increased PTH levels and hypocalciuria. Daily calci...

Seventh UICC/TNM staging criteria for medullary thyroid carcinoma: is there any prognostic advantage?

Martinho M , Azevedo T , Carrilho F , Martins T , Ribeiro C , Melo M , Cunha N , Rascao M J , Neves A , Gilde P , Pires J L , Cruz C , Oliveira C , Neto J , Oliveira S , Valido F , Gomes I , Carvalheiro M , Rodrigues F

Background and aims: The value of the revised (2009) UICC/TNM criteria for medullary thyroid cancer (MTC) is not established. We aimed to evaluate its predictive value, analyzing the consequences of the inclusion of T3N0M0 patients previously included in stage III of the 6th edition, in stage II of the 7th.Patients and methods: We retrospectively analysed the clinical records of 85 patients operated for MTC and followed in two tertiary hospitals in the c...
