High sensitivity, specificity and predictive value of the Connective Tissue Disease Screening Questionnaire among urban African-American women

The Connective Tissue Disease Screening Questionnaire (CSQ), developed to screen populations for SLE and other CTDs, has been validated in a predominantly Caucasian population with hospital-based controls. We aimed to test the performance characteristics of the CSQ in an urban, predominantly African-American population. The CSQ was administered by interview to women recruited for a study of environmental risk factors and SLE, including 99 cases with SLE validated by medical record review and 202 healthy controls recruited from the community. Overall, 88% of subjects had African heritage, 6% were Hispanic and 4% were non-Hispanic Caucasian. Controls were more likely to report African heritage than cases (91% versus 82%, P = 0.001). Sensitivity for detecting SLE was 88% and specificity was 91%. In this study, where the prevalence of SLE was 33%, predictive value of a positive CSQ was 82% and predictive value of a negative CSQ was 94%. The CSQ has slightly lower sensitivity but greater specificity for SLE in an urban, predominantly African-American population with community-based controls compared with a Caucasian population with hospital-based controls. These results suggest that the CSQ has adequate sensitivity and specificity and could be used in population studies to screen African-American women for SLE.

Second-look laparoscopy for visceral ischemia facilitated by preinstalled ports

Much of the information of a second-look laparotomy can be obtained by a second-look laparoscopy. We describe the strategy and technique of installing laparoscopy ports at the end of the primary laparotomy for visceral ischemia to facilitate a second-look laparoscopy in the ensuing 72 hours. The advantages and limitations are illustrated by three cases. The primary advantage appears to be that when second-look laparoscopy can be accomplished at a minimal cost, much of the inhibition to use it is removed. However, more experience is necessary before the procedure can be used to replace laparotomy.
