1. In autonomic failure, supine exercise lowers blood pressure and worsens postural hypotension. The somatostatin analogue, octreotide, reduces post-prandial and postural hypotension, but its effects on exercise-induced hypotension and on postural hypotension post-exercise are unknown. 2. Eighteen subjects with chronic sympathetic denervation were studied; 12 had pure autonomic failure and six ...

In human somatotroph adenomas, growth hormone (GH) hypersecretion can be inhibited by somatostatin analogues such as octreotide. Unfortunately, serum GH levels reach normal values in only 60% of treated patients. The decreased sensitivity to octreotide is strongly related to a lower expression of somatostatin receptor sst2. In this present study, the sst2 gene was transferred by an adenoviral v...

BACKGROUND Octreotide is a somatostatin analog that suppresses insulin secretion. HYPOTHESIS We hypothesized that octreotide would suppress insulin concentrations in horses and that normal (N) horses and those with insulin dysregulation (ID) would differ significantly in their plasma glucose and insulin responses to administration of octreotide. ANIMALS Twelve horses, N = 5, ID = 7. METHO...

OBJECTIVES Somatostatin inhibits lymph production and reduces lymph flow into the lymphatic duct. We hypothesized that octreotide, a long-acting somatostatin analog, would reduce drainage after neck dissection (ND) by reducing the overall lymphatic flow in the neck as well as thoracic duct flow. METHODS From 2012 to 2014, total 123 patients who had undergone left-sided comprehensive ND, were ...

BACKGROUND Angiogenesis is an important determinant of the pathophysiology of portal hypertension contributing to the formation of portosystemic collateral vessels and the hyperdynamic splanchnic circulation associated to this syndrome. Somatostatin and its analogues, like octreotide, have been shown to be powerful inhibitors of experimental angiogenesis. AIM To determine whether octreotide h...

Background. Topical diagnosis of primary hyperparathyroidism (PHPT) remains an urgent problem due to the high incidence persistence and recurrence after surgical treatment. At preoperative stage, a search for parathyroid hormone hyperproduction source is performed using instrumental methods: ultrasound, scintigraphy glands (PTG) multislice computed tomography (MSCT). The cause PHPT parathyroide...

Preoperative control of hyperthyroidism in patients with TSH-secreting pituitary adenomas (TSHoma) may avoid perioperative thyroid storm. Perioperative administration of octreotide may control hyperthyroidism, as well as shrink tumor size. The effects of preoperative octreotide treatment were assessed in a large number of patients with TSHomas. Of 81 patients who underwent surgery for TSHoma at...

Purpose: To demonstrate a rare clinical case of early recurrence verified primary genital lymphoma and the possibility 99mTc-1-Thio-D-glucose (99mTc-TG) SPECT/CT using to brain metastasis diagnosis. Material methods: A patient with diagnosis diffuse large B-cell underwent magnetic resonance imaging (MRI) assess extent disease. Post-treatment follow-up included 18F-FDG PET/CT. diagnose metastasi...

Pancreatic poorly differentiated neuroendocrine tumors (PDNETs) are a subtype of neuroendocrine Tumors (NETs) clinically distinguished by their much more rapid growth and immunohistochemically diagnosed by having a higher Ki-67 cancer cell staining percentage compared to their well or intermediately differentiated NET counterparts. While standard first line treatment for metastatic well or inte...
