Introduction Prophylactic octreotide is controversial in pancreatic surgery in prevention of complications and severity of post-operative pancreatic fistula. We aimed to investigate the influence of prophylactic Octreotide in patients undergoing Pancreaticoduodenectomy and evaluate the cost effectiveness. Methods Prospectively collected data from patients undergoing pancreaticoduodenectomy rese...

CONTEXT Oral administration of a novel octreotide formulation enabled its absorption to the systemic circulation, exhibiting blood concentrations comparable to those observed with injected octreotide and maintaining its biological activity. OBJECTIVES The aim of the study was to determine oral octreotide absorption and effects on pituitary GH secretion compared to sc octreotide injection. D...

AIMS The aim was to assess the pharmacokinetics, pharmacodynamics, safety and tolerability of octreotide subcutaneous (s.c.) depot, a novel octreotide formulation. METHODS This was a phase I, randomized, open label study. After a single dose of octreotide immediate release (IR) 200 µg, subjects were randomized to one of eight groups to receive three monthly injections of octreotide s.c. depot...

BACKGROUND Low uptake ratios, high noise, poor resolution, and low contrast all combine to make the detection of neuroendocrine liver tumours by (111)In-octreotide single photon emission tomography (SPECT) imaging a challenge. The aim of this study was to develop a segmentation analysis method that could improve the accuracy of hepatic neuroendocrine tumour detection. METHODS Our novel segmen...

Chylothorax is the most common cause of pleural effusion in neonates. It is usually idiopathic. Neonatal chylothorax successfully respond to octreotide treatment and can reduce the duration of hospitalization. A number of therapeutic interventions have been used to reduce chyle production and promote resolution of a chylothorax. Initial management typically includes restriction or temporary ces...

OBJECTIVE The aim of this study was to compare the renal function measured with either 99mTc-DTPA or 99mTc-EC dynamic scintigraphies with that measured using 99mTc-DMSA static scintigraphy. METHODS the values of relative renal function measured in 111 renal dynamic scintigraphies performed either with 99mTc-DTPA (55 studies) or with 99mTc-EC (56 studies) were compared with the relative functi...

This study aimed to prepare a novel radiopharmaceutical for the detection of brain disorders at early stages in susceptible patients.Promazine hydrochloride was labeled with 125I by direct electrophilic substitution reaction high labeling yields 92.6 ± 3.24 %. The yield and vitro stability 125I-promazine were determined paper electrophoresis, chromatography (PC) High performance liquid (HPLC). ...

OBJECTIVE Octreotide is used to treat patients with neuroendocrine tumors. Previous reports show that octreotide long-acting repeatable (LAR) dose and patient body weight affect nadir plasma octreotide levels (approximately 1250, 2500, 5000, and 11,000 pg/mL for LAR doses of 10, 20, 30 and 60 mg/mo). However, plasma octreotide levels have decreased over time in patients receiving these doses of...

Abstract Context Paragangliomas located within the pericardium represent a rare yet challenging clinical situation. Objective The current analysis aimed to describe characteristics of cardiac paragangliomas, with emphasis on diagnostic approach, genetic background, and multi-disciplinary management. Methods Twenty-four patients diagnosed paraganglioma in Peking Union Medical College Hospital, B...
