Study design: A face-to-face interview survey. Objective: To compare bowel care patterns in spinal cord injury (SCI) patients based on type of neurogenic bowel. Setting: Department of Physical Medicine and Rehabilitation of a tertiary university hospital in Suwon, Korea. Methods: Among chronic SCI patients, 22 patients with upper motor neuron bowel (UMNB) and 20 patients with lower motor neuron bowel (LMNB) participated in an interview survey for the evaluation of bowel care patterns.
Results:The patients with LMNB demonstrated increased frequency of defecation, increased frequency of fecal incontinence, increased use of oral medications for bowel care, increased required time for defecation and more diet modi®cation than those with UMNB (P50.05). However, there was no signi®cant di erence in the subjective di culty of bowel care. Among several available bowel care methods, suppositories were used most frequently by the UMNB group, whereas the Valsalva maneuver was the most frequently used method by the LMNB group. Conclusions: Patients with LMNB tend to su er more di culties in management of their neurogenic bowel than those with UMNB. Therefore, more intensive and aggressive bowel care programs should be provided for SCI patients with LMNB.
Purpose Avascular necrosis (AVN) of the femoral head is a major complication after internal fixation of a femoral neck fracture and determines the functional prognosis. We investigated postoperative bone single-photon emission computed tomography/computed tomography (SPECT/CT) for assessing the risk of femoral head AVN. Methods We retrospectively reviewed 53 consecutive patients who underwent bone SPECT/CT within 2 weeks of internal fixation of a femoral neck fracture and follow-up serial hip radiographs over at least 12 months. Results Nine patients developed femoral head AVN. In 15 patients who showed normal uptake on immediate postoperative SPECT/CT, no AVN occurred, whereas 9 of 38 patients who showed cold defects of the femoral head later developed AVN. The negative predictive value of immediate postoperative SPECT/CT for AVN was 100 %, whereas the positive predictive value was 24 %. Among 38 patients with cold defects, 1 developed AVN 3 months postoperatively. A follow-up bone SPECT/CT was performed in the other 37 patients at 2-10 months postoperatively. The follow-up bone SPECT/CT revealed completely normalized femoral head uptake in 27, partially normalized uptake in 8, and persistent cold defects in 2 patients. AVN developed in 3.7 % (1/27), 62.5 % (5/8), and 100 % (2/2) of each group, respectively. Conclusions According to the time point of imaging, radiotracer uptake patterns of the femoral head on postoperative bone SPECT/CT indicate the risk of AVN after internal fixation of femoral neck fractures differently. Postoperative bone SPECT/CT may help orthopedic surgeons determine the appropriate follow-up of these patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
