OBJECTIVE Administration of positively charged amino acids has been introduced to reduce the nephrotoxicity of targeted radiopeptide therapy (TRT). However, the amino acid solution may have side effects, including hyperkalaemia. The aim of this study was to evaluate the frequency and the magnitude

Aluminum potassium sulfate and tannic acid (ALTA) injection is a new sclerosing therapy for internal hemorrhoids that has been gaining widespread use. However, there have been few reports about rectal cancer after ALTA injection. We performed laparoscopic surgery for three patients who had underwent

BACKGROUND Peptide receptor radionuclide therapy (PRRT) is routinely used for advanced or metastasized neuroendocrine tumours (NET). To prevent nephrotoxicity, positively charged amino acids (AA) are co-infused. The aim of this study was to correlate the risk for therapy-related hyperkalaemia with

A 32-year-old woman was referred to our hospital because of severe psychosis and was found to have an ectopic ACTH-producing thymic neuroendocrine tumor. Laboratory data revealed an elevated serum cortisol and plasma ACTH level, hypokalemia, and metabolic alkalosis. Chest computed tomography (CT)

Introduction: In recent decades, the number of gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NENs) cases, associated with coexisting metabolic disorders, has been continuously increasing. Patients with progressing neoplastic

Vonoprazan fumarate (Takecab) is a first-in-class potassium-competitive acid blocker that has been available in the market in Japan since February 2015. Vonoprazan is administered orally at 20 mg once daily for the treatment of gastroduodenal ulcer, at 20 and 10 mg once daily for the treatment and

BACKGROUND Peptide receptor radionuclide therapy (PRRT) is applied in patients with advanced neuroendocrine tumors. Co-infused amino acids (AA) should prevent nephrotoxicity. The aims of this study were to correlate the incidence of AA-induced hyperkalemia (HK) (≥5.0 mmol/l) and to identify

Histologically confirmed small cell lung cancer associated with Cushing's syndrome and elevated amylase is rarely described in the literature. We present a case of a 63-year-old patient admitted to cardiology department due to shortness of breath, exhaustion, palpitations and nausea. Elevated values

Multiple endocrine neoplasia type 1 (MEN 1) is characterized by the combined occurrence, to variable degree, of hyperparathyroidism (HPT) (85.7% of cases according to the French Registry of GENEM 1), tumors of the endocrine pancreas (49.6%), pituitary adenomas (38.4%) and, less frequently, adrenal

Pathologic hyperplasia of various pancreatic endocrine cells is rare but has been long known. β cell hyperplasia contributes to persistent hyperinsulinemic hypoglycemia of infancy, which is commonly caused by mutations in the islet ATP-sensitive potassium channel, and to non-insulinoma

OBJECTIVE This review summarizes the past year's literature regarding the regulation of gastric exocrine and endocrine secretion, both basic science and clinical. RESULTS Gastric acid secretion facilitates the digestion of protein as well as the absorption of iron, calcium, vitamin B12, and certain

Pancreatic polypeptide (PP) islet cell tumors are usually not associated with a distinct clinical syndrome, although some reports suggest that they can cause a watery diarrhea syndrome similar to vasoactive intestinal polypeptide (VIP) cell tumors. We report the case of a young woman with an unusual

Pancreatic neuroendocrine tumors represent less than 5% of all pancreatic tumors. They are a heterogeneous group of neoplasms with a diverse behavior and prognosis. Pancreatic vasoactive intestinal polypeptide tumor (VIPoma) is an exceptional tumor within this group due to its low incidence. The

Sunitinib (Sutent®) is a receptor tyrosine kinase (RTK) and angiogenesis inhibitor approved for the treatment of renal cell carcinomas, gastrointestinal stromal tumours and pancreatic neuroendocrine tumours. A key structural motif retained throughout medicinal chemistry efforts during sunitinib's
