Artifactual hypoglycemia describes discrepancy between low capillary and normal plasma glucose levels regardless of symptoms and should be considered in patients with Raynaud's phenomenon. Case presentation: A 46-year-old female patient with a history of a sleeve...
Preoperative Location of Parathyroid Adenomas in Primary Hyperparathyroidism: t...
Amaral, S; Rego, T; Palha, A; Carrilho, N; Coutinho, JM; Tavares, P; Silva-Nunes, JIntroduction: Parathyroid adenoma is the most frequent cause of primary hyperparathyroidism. In recent years, the preoperative location of parathyroid adenomas allowed minimally invasive surgical techniques that have become preferred over the traditional bilateral neck exploration. The more recent guidelines on this subject highlight the role of nuclear medicine imaging tests. The aim of this study was to revie...
A Common Variant in the CDK8 Gene Is Associated with Sporadic Pituitary Adenoma...
Gaspar, L; Gonçalves, C; Fonseca, F; Carvalho, D; Cortez, L; Palha, A; Barros, I; Nobre, E; Duarte, J; Amaral, C; Bugalho, MJ; Marques, O; Pereira, BThe majority of pituitary adenomas occur in a sporadic context, and in the absence of known genetic predisposition. Three common variants at the NEBL (rs2359536), PCDH15 (rs10763170) and CDK8 (rs17083838) loci were previously associated with sporadic pituitary adenomas in the Han Chinese population, but these findings have not yet been replicated in any other population. The aim of this case-control study was t...
Leydig Cell Tumour and Mature Ovarian Teratoma: Rare Androgen-Secreting Ovarian...
Palha, A; Cortez, L; Tavares, AP; Agapito, AAndrogen-secreting ovarian tumours are extremely rare accounting for <5% of all ovarian neoplasms. They are more frequent in postmenopausal women and should be suspected in the case of a rapid onset of androgenic symptoms. We report 4 cases of postmenopausal women who presented with signs of virilisation. All patients revealed increased serum levels of testosterone, normal dehydroepiandrosterone-sulfate and neg...
