Cecal volvulus is an uncommon cause of colonic obstruction. First-line treatment for cecal volvulus is surgery, as nonoperative management is rarely achievable. We herein report an extremely rare case of a patient with spontaneously resolved cecal volvulus; no recurrence occurred without elective surgery. A 47-year-old woman presented with acute lower abdominal pain. She was misdiagnosed with small bowel obstruction and treated conservatively. A few hours later, she was correctly diagnosed with cecal volvulus. Subsequently, her symptoms and computed tomography findings of cecal volvulus completely disappeared. She refused elective surgery, but no recurrence occurred during five months of follow-up. 相似文献

Pulp fibroblasts were isolated from human deciduous and supernumerary teeth and cultured in vitro. With continued culture in normal tissue-culture medium, six pulp fibroblast strains formed cell nodules after 10–15 days. By electron microscopy the nodules had matrix vesicles, and needle-shaped crystals associated with a dense network of collagen fibrils. The crystalline material exhibited a pattern consistent with hydroxyapatite when nodules were examined by X-ray diffractometry. Furthermore, the cells showed high levels of alkaline phosphatase activity, which could be increased more than seven-fold by the addition of 1,25(OH)2D3 (5 × 10−9−5 × 10−8M). In addition to the production of type I collagen, these cells also synthesized fibronectin and osteonectin. The formation of mineralized tissue nodules by pulp cells in vitro provides a useful system for study of the pathological calcification of pulp tissues. 相似文献

This is the first report of a case of seminal vesiculitis prior to acute chlamydial epididymitis. At the first visit to the
clinic, the patient wished to check whether he had Chlamydia trachomatis in his genital tract, because his wife had been diagnosed as having chlamydial cervicitis. He had no specific symptoms at
that time; however, transrectal ultrasonograpy (TRUS) revealed swelling of seminal vesicles, which suggested the presence
of seminal vesiculitis. Two days after the first visit, he had high-grade fever and was diagnosed as having acute epididymitis
caused by C. trachomatis. We had previously reported that seminal vesiculitis was always complicated with acute epididymitis, so this case could provide
important evidence that seminal vesiculitis might precede acute epididymitis. It suggested that acute epididymitis could be
affected by seminal vesiculitis via the retrograde transmission route. 相似文献

Purpose
To evaluate the clinical impact on progression and recurrence according to presence and absence of a muscle layer, we conducted a retrospective, multicenter study.Methods
We retrospectively reviewed 247 patients who received transurethral resection (TUR) of bladder tumors and were pathologically diagnosed as having T1G3 bladder cancer from 1990 to 2009. We ruled out 8 patients who received immediate cystectomy and analyzed the remaining 239 T1G3 patients. Patients who had invasion to the prostatic urethra and patients who underwent a second TUR were not included.Results
TUR specimens from 194 patients were confirmed to have a definite muscle layer and those from 45 did not. The median follow-up period was 53 months, ranging from 3 to 181 months. The progression-free survival rates at 5 years after TUR were 91.1 % for patients who had a muscle layer in their specimen and 77.3 % for those who did not (p = 0.005, log-rank test). Multivariate analysis indicated that the absence of a muscle layer was a risk factor for progression (p = 0.006, Cox proportional hazards analysis).Conclusions
Patients without a muscle layer in the specimen had high risk for progression. The initial TUR must have a muscle layer in the specimen. Variations of progression rates in previous studies might be due to different proportions of patients who had a muscle layer in TUR specimens. 相似文献9.
