Brooks HaysBETHESDA, Md., Dec. 4 (UPI) -- Researchers now believe gene duplication in a specific chromosome region, key in growth regulation, is responsible for the rare disorder known as gigantism.

Authors: Fuentes-Fayos AC, García-Martínez A, Herrera-Martínez AD, Jiménez-Vacas JM, Vazquez-Borrego MC, Castaño JP, Picó A, Gahete MD, Luque RM Abstract Acromegaly is a chronic systemic disease mainly caused by a growth hormone (GH)- secreting pituitary neuroendocrine tumor (PitNETs), which is associated with many health complications and increased mortality when not adequately treated. Transsphenoidal surgery is considered the treatment of choice in GH-secreting PitNETs, but patients in whom surgery cannot be considered or with persistent disease after surgery require med...

Authors: Goltzman D Abstract Primary hyperparathyroidism is among the most common causes of hypercalcemia. However, ingestion of medication, including hydrochlorathiazide, lithium, and foscarnet, excessive vitamin A ingestion, endocrinopathies such as hyperthyroidism, adrenal insufficiency, and acromegaly, abnormal nutrient intake such as parenteral nutrition in preterm infants and milk-alkali syndrome, and prolonged immobilization have all been associated with hypercalcemia. The most common cause of nonparathyroid hypercalcemia is neoplasia. Hypercalcemia is generally due to the secretion of parathyroid hormone (P...

Koonin, Natalya YutinAbstractThe Nucleocytoplasmic Large DNA Viruses (NCLDV) of eukaryotes (proposed order “Megavirales”) comprise an expansive group of eukaryotic viruses that consists of the families Poxviridae, Asfarviridae, Iridoviridae, Ascoviridae, Phycodnaviridae, Marseilleviridae, Pithoviridae, and Mimiviridae, as well as Pandoraviruses, Molliviruses, and Faustoviruses that so far remain unaccounted by the official virus taxonomy. All these viruses have double-stranded DNA genomes that range in size from about 100 k...

We report an unusual plurihormonal tumor co-expressing Pit-1 and SF-1 along with hormones made by cells of both lineages. Its simultaneous occurrence adjacent to a corticotroph tumor raises questions regarding the pathogenesis of these tumors. We pr opose the possibility of a stem cell tumor with multiple lineage differentiation. We hypothesize that pregnancy might have played a permissive role in tumorigenesis.

A growth hormone-secreting adenoma of the anterior pituitary gland is the most common cause of acromegaly. Metabolic and somatic features of acromegaly caused by high serum concentrations of insulin-like growth factor-I (IGF-I) and excess growth hormone (GH) production. we present a case of ‘pseudoacromegaly’ with a...
