TASK DEFINITION: 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.
PROBLEM: One variant of multiple endocrine neoplasia type 1 (MEN1) is defined by sporadic tumors of both the parathyroids and pituitary. The prevalence of identified MEN1 mutations in this variant is lower than in familial MEN1 (7% vs. 90%), suggesting different causes. Recently, one case of this variant had a germline mutation of p27(Kip1)/CDKN1B.', 'The objective was to test p27 in germline DNA from cases with tumors of both the parathyroids and pituitary.', 'Medical record review and sequence analysis in DNA were performed.', 'This study involved an inpatient and outpatient referral program for cases of endocrine tumors.', 'Sixteen index cases had sporadic tumors of two organs, both the parathyroids and the pituitary. There were 18 additional index cases with related features of familial tumors. Five subjects were normal controls. No case had an identified MEN1 mutation.', 'Clinical status of endocrine tumors was tabulated. Sequencing of germline DNA from index cases and control cases for the p27 gene was performed by PCR.', 'Endocrine tumor types and their expressions were measured, as were sequence changes in the p27 gene.', 'Tumor features were documented in index cases and families. One p27 germline single nucleotide change was identified. This predicted a silent substitution of Thr142Thr. Furthermore, there was a normal prevalence of heterozygosity for a common p27 polymorphism, making a large p27 deletion unlikely in all or most of these cases.

SOLUTION: Does the parathyroid/pituitary variant of multiple endocrine neoplasia type 1 usually have causes other than p27Kip1 mutations?

PROBLEM: Longer-term tuberculosis (TB) drug resistance surveillance among children is rare. We determined the prevalence of drug resistance among children with culture-confirmed TB from 2011 to 2013, compared these results with four previous consecutive 2-year periods and documented other mycobacterial isolates identified.', "Surveillance study of mycobacterial culture in all children aged <13 years conducted from March 2011 to February 2013 at the Tygerberg Children's Hospital, Cape Town, South Africa. Drug susceptibility testing against isoniazid (INH) and rifampicin (RMP) was performed using line-probe assay (GenoType(®) MTBDRplus). Clinical data were obtained through folder review.", 'Of 381 children, 323 (84.8%; 324 episodes) had Mycobacterium tuberculosis, 46 (12.1%) had M. bovis bacille Calmette-Guérin and 12 (3.1%) had non-tuberculous mycobacteria isolated. Forty-one (12.7%) children had M. tuberculosis resistant to INH and/or RMP; 15 (4.7%) had multidrug-resistant TB (MDR-TB). The prevalence of INH mono- or polyresistance remained stable; however, RMP monoresistance increased (0/313 in 2003-2005 vs. 6/324, 1.9%, in 2011-2013; P = 0.041); MDR-TB prevalence has declined significantly, from 26/292 (8.9%) in 2007-2009 to 15/324 (4.7%) in 2011-2013 (OR 0.50, 95%CI 0.24-0.99). The prevalence of human immunodeficiency virus co-infection has decreased significantly, from a peak of 29% to 15.3%.

SOLUTION: Does surveillance provide insight into epidemiology and spectrum of culture-confirmed mycobacterial disease in children?

PROBLEM: We investigated whether high prolactin levels were associated with delirium in septic patients because neuropsychiatric disorders are frequently associated with hyperprolactinemia.', 'Prolactin levels were measured daily for 4 days in 101 patients with sepsis. Delirium was assessed using the Richmond Agitation Sedation Scale and the Confusion Assessment Method in the ICU.', 'Delirium developed in 79 patients (78%) and was more common in patients older than 65 years. Prolactin levels were higher in patients with delirium than in those without over the 4 days of observation (P = .032). In patients with delirium, higher prolactin levels were associated with a lower incidence of nosocomial infection (P = .006). Multivariable logistic regression showed that the Sequential Organ Failure Assessment score at intensive care unit admission (odds ratio, 1.24; 95% confidence interval, 1.04-1.48; P = .002) and the combined effect of prolactin levels with age (odds ratio, 1.018; 95% confidence interval, 1.01-1.031; P = .006) were associated with the development of delirium.

SOLUTION:
Are high prolactin levels associated with more delirium in septic patients?
