In Japan, community–based education remains uncommon in undergraduate programs for students in schools of health sciences. The purpose of this study was to examine how students are affected by their participation in off–campus classes, which are considered as a main course of community–based education at the School of Health Sciences, Gunma University.
1)Reports submitted by students after participating in off–campus classes were broken down into sentences (with care being taken that each sentence made sense). The extracted sentences were carefully consolidated by means of the Kawakita Jiro method (affinity diagram).
2)A total of 972 sentences were extracted and were categorized into 3 categories: "enjoy going out to the community," "increased activity through experiences," "awareness of what one wants to be and one's insufficient abilities." Five middle–sized categories and 10 small categories were obtained.
3)Experiences in off–campus classes are expected to increase the activity of students and to have synergic effects with on–campus classes.
4)Community–based education might be effectively included in undergraduate programs for students in schools of health sciences.

Methods:
A total of 400 patients (175 men, 225 women) who underwent PLIF were observed for >1 year. Factors investigated included the frequency of cage retropulsion and surgical revision. In addition, physical (age, sex, disease), surgical (fusion and PLIF levels, cage number, grade 2 osteotomy), and comorbid (DISH, existing vertebral fracture) factors were compared between patients with and without cage retropulsion. Factors related to surgical revision during the observation period were also considered.
Results:
Cage retropulsion occurred in 15 patients and surgical revision was performed in 11. Revisions included the replacement of pedicle screws (PSs) with larger screws in all patients and supplementary implants in 10. Among the patients with cage retropulsion, the average PLIF level was 2.7, with DISH present in nine patients and existing vertebral fractures in six. Factors affecting cage retropulsion were diagnoses of osteoporotic vertebral fracture, multilevel fusion, single-cage insertion, grade 2 osteotomy, presence of DISH, and existing vertebral fracture. Multivariable analysis indicated that retropulsion of a fusion cage occurred significantly more frequently in patients with DISH and multilevel PLIF.
Conclusions
DISH and multilevel PLIF were significant risk factors affecting cage retropulsion. Revision surgery for cage retropulsion revealed PS loosening, suggesting that implant replacement was necessary to prevent repeat cage retropulsion after revision.

Methods:
We observed 141 patients (61 men, 80 women; average age, 65.8 years) who had undergone PLIF and checked for the presence of L5/S interbody fusion. We investigated factors such as age, gender, the presence of diffuse idiopathic skeletal hyperostosis (DISH), fusion level, and grade 2 osteotomy, as well as pre-, post-, and post−preoperative L5/S disk height and angle, lumbar lordosis, Visual Analog Scale (VAS) score, Japanese Orthopaedic Association (JOA) score, and pelvic incidence (PI), comparing those with and without L5/S interbody fusion. In addition, we analyzed the patients classified into short-level (n=111) and multi-level fusion groups (n=30).
Results:
Overall, the L5/S interbody fusion rate was 70% (short-level, 78%; multi-level, 40%). Age and pre- and post−preoperative L5/S disk angle were significantly different in each fusion level group. DISH presence, grade 2 osteotomy, and postoperative VAS and JOA scores were significantly different in the short-level fusion group, whereas PI was significantly different in the multi-level fusion group.
Conclusions
Incomplete union after L5/S PLIF correlates with advanced age, many fusion levels, and a large value of preoperative and a small value of post−preoperative L5/S disk angles.

OBJECTIVETo characterize the symptoms of neurogenic intrapelvic syndrome and the pathogenic mechanisms.
METHODSA total of 537 patients with neurogenic intrapelvic syndrome were treated in the Takano Hospital between 2001 and 2005. Clinical data were analyzed retrospectively.
RESULTSThe mean age was 58.5 years old. There were 205 males and 332 females. There were 80 patients(14.9%) who presented with only one symptom with anorectal pain being the most common one (43.8%, 35/80). One hundred and fifty-six(29.1%) patients had two symptoms with anorectal pain and difficult evacuation being the most common combination (26.3%, 41/156). There were 144 patients (26.8%) complained of 3 symptoms and the most common combination was anorectal pain, difficult evacuation, and abdominal discomfort (30.0%, 43/144). A combination of 4 symptoms was reported in 105 patients(19.6%) with the combination of anorectal pain, incontinence, abdominal discomfort, and lumbar discomfort being the most often(65.7%, 69/105). In addition, there were 52 patients(9.7%) who had above 5 symptoms simultaneously. The frequencies of the 5 symptoms were 73.6% for anorectal pain, 27.9% for incontinence, 69.6% for difficult evacuation, 55.3% for abdominal discomfort, and 53.6% for lumbar discomfort.
CONCLUSIONSSymptomatology of neurogenic intrapelvic syndrome is complicated. The pathogenic mechanism may be related to concurrent dysfunction of sacral nerve and pelvic splanchnic nerve.
