We report a case of laparoscopic surgery for a rectal carcinoid after aluminum potassium and tannic acid (ALTA) therapy for an internal hemorrhoid. A 66-year-old man was admitted to our hospital because of bleeding during defecation. He was diagnosed via anoscopy with Goligher grade II internal
BACKGROUND
Previous data from our laboratory has indicated that there is a functional link between the beta-adrenergic receptor signaling pathway and the G-protein inwardly rectifying potassium channel (GIRK1) in human breast cancer cell lines. We wanted to determine if GIRK channels were expressed
BACKGROUND
Pergolide produces clinical benefit in Parkinson disease by stimulating dopamine D1 and D2 receptors. An increased incidence of carcinoid-like heart valve disease (CLHVD) has been noted in pergolide users, reminiscent of that induced by certain anorexigens used for weight reduction.
We report the case of a woman with a history of chronic alcohol abuse who was hospitalized with diarrhea, severe hypokalemia refractory to potassium infusion, nausea, vomiting, abdominal pain, alternations of high blood pressure with phases of hypotension, irritability and increased urinary
Intestinal handling of water and electrolytes was monitored in 5 conscious dogs with chronic 25-cm Thiry-Vella loops of proximal jejunum using a neutral isosmotic perfusate containing [14C]polyethylene glycol as a recovery marker. Under basal conditions the animals absorbed water, Na+, and Cl-, and
OBJECTIVE
The aim of this study was to assess the effects of the long-acting release (LAR) depot octreotide preparation Sandostatin LAR Depot on stool water and electrolyte losses, fecal fat excretion, and GI transit in patients with short bowel syndrome.
METHODS
We performed a 15-wk, prospective,
Over the past ten years there have been major advances in the physician's ability to treat patients with peptic ulcer disease. Cimetidine continues to be the standard against which newer therapies are generally compared, although ranitidine is equally effective for short-term therapy, more effective
Both severe hypokalemia and persistent hypertension are clinical symptoms of hyperaldosteronism. Hyperaldosteronism may occur as a primary or secondary syndrome. Excess ACTH produced ectopically by tumors may induce hyperaldosteronism through the mineralocorticoid activity of glucocorticoids that
Rabeprazole, a new benzimidazole proton pump inhibitor (PPI), is among a class of agents known to be very potent inhibitors of gastric acid secretion. PPIs inhibit hydrogen-potassium adenosine triphosphatase activity on the luminal surface of the parietal cell, effectively blocking the final common
BACKGROUND
The potassium channel I(Ks), which is encoded by the KCNQ1 gene, is expressed in organ systems including the inner ear, kidneys, lungs, intestine, and stomach in addition to the heart. Increasing evidence indicates that I(Ks) in the stomach plays an essential role in enabling gastric acid
The pulmonary neuroendocrine cell (PNEC) system consists of solitary cells and distinctive cell clusters termed neuroepithelial bodies (NEB) localized in the airway epithelium. PNEC/NEB express a variety of bioactive substances, including amine (serotonin, 5HT) and neuropeptides. We have previously
Hypotension is defined by a low blood pressure either permanently or only in upright posture (orthostatic hypotension). In contrast to hypertension, there is no threshold defining hypotension. The occurrence of symptoms for systolic and diastolic measurements respectively below 90 and 60 mm Hg
The development and introduction into clinical practice of proton pump inhibitors (PPIs) have influenced the management of acid-peptic disorders dramatically. PPIs inhibit the gastric hydrogen/potassium adenosine triphosphatase selectively and irreversibly which is the final step in acid secretion.
BACKGROUND
Endogenous Cushing's syndrome is a clinical state resulting from prolonged, inappropriate exposure to excessive endogenous secretion of cortisol and hence excess circulating free cortisol, characterized by loss of the normal feedback mechanisms of the hypothalamo-pituitary-adrenal axis
This study was initiated to determine if raised (carcinoid) plasma concentrations of substance P induced jejunal secretion of water and electrolytes. Five dogs had isolated and cannulated 25 cm jejunal segments perfused at 2 ml/min with a neutral, isotonic perfusate. Saline, 1.0 ml, was infused
