Given a passage, 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.

Input: Consider Input: Prevention of intraabdominal abscess formation constitutes an important goal in treatment of secondary peritonitis. Fibrinolytic therapy may be effective in this respect. The efficacy of recombinant tissue plasminogen activator (rtPA) and urokinase is compared in a preclinical model for surgical treatment of peritonitis.', 'Peritonitis was induced by intraperitoneal bacterial challenge in male Wistar rats. After 1 hour, surgery was performed. Four groups (n = 20) were treated with one of the following: rtPA, urokinase, streptokinase (a negative protein control), or saline. Blood cultures were taken at 6 and 24 hours; cell counts and cytokine measurements were performed in peritoneal fluid at 1, 3 and 5 days. After 5 days, animals were killed and intraperitoneal abscess formation was analyzed.', 'Both rtPA and urokinase strongly (> 75%) and significantly (P < .05) reduced abscess formation without negative side effects. No bleeding complications were observed. Fibrinolytic therapy altered the intraperitoneal cellular distribution (less neutrophils and more macrophages) but did not essentially alter the courses of interleukin-6 and interleukin-10 (decreasing in time) or tumor necrosis factor-* (increasing in time) levels.

Output: Do both tissue-type plasminogen activator and urokinase prevent intraabdominal abscess formation after surgical treatment of peritonitis in the rat?


Input: Consider Input: To conduct clinical and genetic studies in a European family with autosomal dominant Stargardt-like macular dystrophy (adSTGD-like MD) and to investigate the functional consequences of a novel ELOVL4 mutation.', 'Ophthalmic examination and mutation screening by direct sequencing of the ELOVL4 gene was performed in two affected individuals. Wild-type and mutant ELOVL4 genes were expressed as enhanced green fluorescent protein (EGFP) fusion proteins in transient transfection in NIH-3T3 and HEK293 cells. To determine the subcellular localization of ELOVL4, an endoplasmic-reticulum (ER)-specific marker for pDsRed2-ER was cotransfected with ELOVL4 constructs. Transfected cells were viewed by confocal microscopy. Western blot analysis was performed to assess protein expression using an anti-GFP antibody.', 'Affected patients exhibited macular atrophy with surrounding flecks characteristic of adSTGD-like MD. A novel ELOVL4 p.Tyr270X mutation was detected in affected individuals. In cell-transfection studies, wild-type ELOVL4 localized preferentially to the ER. In contrast, the mutant protein appeared to be mislocalized within transfected cells.

Output: Does a novel mutation in the ELOVL4 gene cause autosomal dominant Stargardt-like macular dystrophy?


Input: Consider Input: In burn care, a well-acknowledged problem is the suboptimal scar outcome from skin grafted burn wounds. With the aim of improving this, we focused on a new technique: excision of the burn wound followed by primary closure, thereby using a skin-stretching device to stretch the adjacent healthy skin. The short- and long-term effect of Skin Stretch was compared to split skin grafting (SSG) in a randomized controlled trial.', 'Patients with burn wounds were randomized for SSG or primary wound closure using Skin Stretch. Follow-up was performed at 3 and 12 months postoperatively. The scar surface area was calculated and the scar quality was assessed, using subjective and objective measurement methods.', 'No significant differences between the SSG and the Skin Stretch group were found for scar surface area. In the Skin Stretch group, a significant reduction of the surface area from 65.4cm(2) (13.6-129.1) to 13.4cm(2) (3.0-36.6) was found at 3 months (p=0.028) and at 12 months postoperatively (65.4cm(2) (13.6-129.1) to 33.0cm(2) (8.9-63.7), p=0.046, Wilcoxon signed ranks test).


Output: Do skin stretching for primary closure of acute burn wounds?
