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.

Question: Context: It is recommended that dentists screen for dental anxiety (DA) so that fearful patients may be better managed. The main aim of this study was to determine what dentists are being taught in relation to DA as well as whether and how anxious patients are identified in the clinic.', 'Two hundred and forty-six practising dentists (adjusted response rate = 40.1%), from a random sample of registered Australian dentists, completed a mailed questionnaire.', "Dentists estimated that high DA affected 23.3% of children and 19.4% of adults seen. Only 3.7% of dentists reported using a published scale for screening DA, with the most common reason being lack of awareness (56.5%). Approximately one-half of responding dentists directly asked their patients about DA and this was more common among younger dentists (χ(2) = 7.75, p = 0.021). There were few differences in DA screening by other practitioner or practice characteristics (p > 0.05). Only one-third of dentists had received undergraduate training related to DA and only 41.7% considered this to be 'good' or better. Almost 37% of respondents expressed an interest in future training opportunities.
Answer: The use of formal, validated scales for screening DA is minimal. Training in anxiety management appears to be low and is an area that could be expanded upon.

Answer: Does dental anxiety screening practices and self-reported training need among Australian dentists?


Question: Context: Completeness of cytoreduction is a significant predictor of long-term outcome after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Imaging has limited sensitivity to identify peritoneal metastases and therefore predict whether complete cytoreduction is possible. We reviewed our experience using laparoscopy to determine candidates for complete cytoreduction and HIPEC.', 'This single-center, retrospective study examined patients from 2007 to 2014 who underwent laparoscopy to determine complete cytoreduction (CC-0/1)/HIPEC candidacy. Preoperative, intraoperative, and postoperative data were collected.', 'A total of 145 laparoscopies were performed on 141 patients, 72 (51.1\xa0%) of whom were female, with a median age of 53\xa0years (range 20-79). The primary site was appendiceal in 67 (47.5\xa0%) patients, colorectal in 43 (30.5\xa0%), mesothelioma in 17 (12.1\xa0%), unknown in 9 (6.4\xa0%), small bowel in 3 (2.1\xa0%), gastric in 1, and ovarian in 1 (0.7\xa0% each). Overall, 115 (81.6\xa0%) patients had prior abdominal surgery, 111 (76.6\xa0%) had evidence of disease on imaging, and 117 (80.7\xa0%) underwent prior chemotherapy, with a median of 5.9\xa0weeks between the last treatment and laparoscopy (0.9-498.9\xa0weeks). Four (2.8\xa0%) intraoperative complications were observed (one liver laceration, two enterotomies, and one air embolus), and nine (6.2\xa0%) postoperative complications [four (2.8\xa0%) Clavien grade (CG) I, three (2.8\xa0%) CG II, one (0.7\xa0%) CG III (return to operating room) and one (0.7\xa0%) CG IV (transient ischemic attack)]. Forty-eight patients deemed candidates by laparoscopy underwent CRS/HIPEC (positive predictive value 82.8\xa0%).
Answer: Diagnostic laparoscopy is a safe, feasible, and accurate staging tool in patients with suspected peritoneal metastases being considered for CRS.

Answer: Is laparoscopy Safe and Accurate to Evaluate Peritoneal Surface Metastasis Prior to Cytoreductive Surgery?


Question: Context: To investigate the effect of recurrent laryngeal nerve (RLN) identification on the complications after total thyroidectomy and lobectomy.', 'Total 134 consecutive patients undergoing total thyroidectomy or thyroid lobectomy from January 2003 to November 2004 were investigated retrospectively. Patients were divided into two groups: RLN identified (Group A) or not (Group B). The two groups were compared for RLN injury and hypocalcaemia.', 'The numbers of patients and nerves at risk were 71 and 129 in Group A, and 63 and 121 in Group B, respectively. RLN injury in Group A (0) was significantly lower than that in Group B (5 [7.9%]) patients, 7 [5.8%] nerves) for the numbers of patients (P=0.016) and nerves at risk (P=0.006). Temporary hypocalcaemia was significantly higher in Group A than in Group B (14 [24.1%] vs 6 [10.3%], P=0.049). Permanent complications in Group B were significantly higher than those in Group A (13 [20.6%] vs 4 [5.6%], P=0.009).
Answer: RLN injury was prevented and permanent complications were decreased by identifying the whole course and branches of the recurrent laryngeal nerve during total thyroidectomy.

Answer:
Is total thyroidectomy safer with identification of recurrent laryngeal nerve?
