Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Ex Input:
Context: Parenteral control of gastric acid hypersecretion in conditions such as Zollinger-Ellison syndrome (ZES) or idiopathic gastric acid hypersecretion is necessary perioperatively or when oral medications cannot be taken for other reasons (e.g., during chemotherapy, acute upper gastrointestinal bleeding, or in intensive care unit settings).', 'We evaluated the efficacy and safety of 15-minute infusions of the proton pump inhibitor pantoprazole (80-120 mg every 8-12 hours) in controlling acid output for up to 7 days. Effective control was defined as acid output >10 milliequivalents per hour (mEq/h) (<5 mEq/h in patients with prior acid-reducing surgery) for 24 hours.', 'The 21 patients enrolled had a mean age of 51.9 years (range, 29-75) and a mean disease duration of 8.1 years (range, <0.5-21); 13 were male, 7 had multiple endocrine neoplasia syndrome type I, 4 had undergone acid-reducing surgery, 2 had received chemotherapy, and 13 had undergone gastrinoma resections without cure. Basal acid output (mean +/- SD) was 40.2 +/- 27.9 mEq/h (range, 11.2-117.9). In all patients, acid output was controlled within the first hour (mean onset of effective control, 41 minutes) after an initial 80-mg intravenous pantoprazole dose. Pantoprazole, 80 mg every 12 hours, was effective in 17 of 21 patients (81%) for up to 7 days. Four patients required upward dose titration, 2 required 120 mg pantoprazole every 12 hours, and 2 required 80 mg every 8 hours. At study end, acid output remained controlled for 6 hours beyond the next expected dose in 71% of patients (n = 15); mean acid output increased to 4.0 mEq/h (range, 0-9.7). No serious or unexpected adverse events were observed.
Answer: Intravenous pantoprazole, 160-240 mg/day administered in divided doses by 15-minute infusion, rapidly and effectively controlled acid output within 1 hour and maintained control for up to 7 days in all ZES patients.

Ex Output:
Does intravenous pantoprazole rapidly control gastric acid hypersecretion in patients with Zollinger-Ellison syndrome?


Ex Input:
Context: To investigate localization and distribution of integrin subunit β1, β2 and β3 and morphological changes of ligand-recepter binding in thrombi of acute pulmonary embolism (PE) patients and explore activation of circulated immune cells, inflammatory immune adherence and coagulation response in acute venous thrombosis.', 'Thrombi were collected from patients with acute PE. Immunohistochemistry was done to detect the expression and distribution of integrin β1, β2 and β3 in cells within thrombi, and ligands of integrin subunit β1, β2 and β3 were also determined by immunohistochemistry within the thrombi.', '1) Acute venous thrombi were red thrombi composed of skeletons and filamentous mesh containing large amounts of red blood cells and white blood cells; 2) Integrin subunit β1, β2 and β3 were expressed on lymphocytes, neutrophils and platelets; 3) No expression of integrin β1 ligands: Laminin, Fibronectin, Collagen I or Collagen-II on lymphocytes; integrin β2 ligands including ICAM, factor X and iC3b are distributed on neutrophils, and ligand fibrinogen bound to neutrophils; integrin β3 was expressed on platelets which form the skeleton of thrombi and bound to fibrinogen to construct mesh structure; 4) Factor Xa was expressed on the filamentous mesh; 5) Filamentous mesh was fully filled with red blood cell dominant blood cells.
Answer: Acute venous thrombosis is an activation process of circulated lymphocytes, neutrophils and platelets mainly, and a whole process including integrin subunit β2 and β3 binding with their ligands. Activation of immune cells, inflammatory immune adherence and coagulation response are involved in the acute venous thrombosis.

Ex Output:
Are activation of circulated immune cells and inflammatory immune adherence involved in the whole process of acute venous thrombosis?


Ex Input:
Context: the study was aimed at assessment of the efficacy of percutaneous high frequency selective rhizotomy (PHFSR) after failure of conservative treatment of trigeminal neuralgia (TN) in multiple sclerosis (MS).', "A retrospective analysis of 28 patients with TN associated with MS who underwent percutaneous rhizotomy in the period from 2000 to 2014 was performed. All patients were definitely diagnosed with MS according to the McDonald criteria (version of 2001, 2005, and 2010). The patients were divided by age, gender, and the trigeminal nerve branches involved in the process. The patients' condition was evaluated at different times after surgery.", 'Good outcomes in the form of pain syndrome regression were achieved in 100% of the patients. A disease recurrence was observed in 6 (21%) patients during a follow-up period of 3 months to 14 years. Dysesthesia complications occurred in 4 (14%) patients. There were no deaths and severe complications. The percentage of minor complications was low.
Answer: These data confirm that PHFSR is a safe, repeatable, and effective method of symptomatic neurosurgical treatment of TN associated with MS and may be recommended in the case of failure/intolerance of medication.
