Devices are now available that are practical for point of care testing (PCT) in hospital settings. Previous studies in clinical settings, however, have failed to demonstrate a reduction in patients' length of stay (LOS) associated with the use of PCT. This randomized controlled study compared PCT with central laboratory testing in a hospital Emergency Department to assess the difference in patients' LOS. Patients randomized to PCT (n = 93) had a median stay of 3 h, 28 min (interquartile range [IR] 2:28 to 5:30), while those allocated to the central laboratory (n = 87) had a median stay of 4 h, 22 min (IR 3:04 to 5:47). The median stay associated with PCT was significantly shorter. Among patients who were destined to be discharged home, there was also a significantly shorter stay, but not among those who were destined to be admitted. It was concluded that the use of PCT can achieve significant time savings in an Emergency Department.

Department of Pediatric Surgery, Tongji Medical College, Union Hospital, Huazhong University of Science and Technology, Wuhan 430015, China.
Background And Study Aims: Hirschsprung disease (HD) is a complex developmental disease that resulted from impaired proliferation and migration of neural crest cells. Despite the genetic causation of enteric nervous system have been found to be responsible for part of HD cases, the genetic aetiology of most HD patients still needs to be explored.
Patients And Methods: Whole-genome sequencing and subsequent Sanger sequencing validation analysis were performed in 13 HD children and their unaffected parents.
