Torsions of the spermatic cord occurring from the intrauterine period to the end of the first year of life are termed perinatal. These are divided into prenatal and postnatal torsions, depending on their occurrence in the intrauterine or postuterine period. From January 1984 to January 1996, 6 cases were identified at our institution, involving 4 prenatal and 2 postnatal extravaginal torsions of the spermatic cord. These cases are reviewed with regard to optimal therapeutic approaches for the treatment of both the affected gonad as well as the contralateral one, and whether the event occurred prenatally or postnatally. The authors also propose several clinical indications useful for obstetricians, pediatricians, urologists and nurses. 相似文献

Purpose:
Despite advances in surgical treatment options, large rotator cuff (r-c) tears still represent a challenge for orthopedic surgeons. The purpose of this study was to evaluate the temporary and spatial histological incorporation of fascia lata allografts, used for bridging artificially created defects of the r-c.Materials and Methods:
Seventy-two rabbits were divided into two groups and a supraspinatus tendinous defect was created. Half of the rabbit population underwent repair only, while in the other half, the defect was bridged utilizing fascia lata allograft. The animals were euthanized at 2, 4, and 6 weeks postoperative. Half of the specimens were evaluated histologically and the other half underwent mechanical testing.Results:
There was an increased remodeling activity, fibroblastic in growth and strong presence of collagen fibers observed at 6 weeks on both groups. A gradually increasing mechanical strength was noticed by week 6 and increased toughness was also found at the same time period. There was no significant difference observed between the two groups regarding their histological and mechanical properties.Conclusions:
In the difficult scenario of a large irreparable tear where the simple suture of the remaining r-c is impossible, allograft bridging, could be used with satisfactory results.Clinical Relevance:

Throughout the past six decades, our understanding of cancer of the prostate and the treatment of the disease using endocrine therapy has been centred on the classical investigations of Charles Huggins, which established that tumor tissue of the prostate as well as the normal tissue of the gland retained some degree of androgen dependence. Attention must now be focussed on the 20-40% of patients who are resistant to endocrine therapy. These patients are non-responders to conventional endocrine treatment after 3 to 6 months, quickly progress and die of the disease. In terms of molecular endocrinology related to the progressive stage of the disease, it would be expected that the cancer is being driven by the uncontrolled action of growth factors. Experiments combining oligonucleotide treatment with cytotoxic chemotherapeutic agents demonstrated a marked increase in the sensitivity of the prostate cancer cells. Results indicate that despite the presence of Bcl-x pre-mRNA in a number of cell types, the effects of modification of its splicing by antisense oligonucleotides vary depending on the expression profile of the treated cells. The transition from androgen-dependent to androgen non-dependent prostate cancer is accompanied by a number of molecular genetic changes, including overexpression of the Bcl-2 gene. Overexpression of Bcl-2 protein decreases the pro-apoptotic response to such cellular insults as irradiation, chemotherapy, and androgen withdrawal. The future looks promising and this kind of treatment offers a novel approach to alternative therapeutic options for advanced prostate cancer. Although numerous chemotherapeutic regimens have been evaluated for patients with hormone-refractory prostate cancer, none has improved survival. 相似文献

Capsule endoscopy is an easy and painless procedure permitting visualization of the entire small-bowel during its normal peristalsis. However, important problems exist concerning capsule retention in patients at risk of small bowel obstruction. The present report describes a young patient who had recurrent episodes of overt gastrointestinal bleeding of obscure origin, 18 years after small bowel resection in infancy for ileal atresia. Capsule endoscopy was performed, resulting in capsule retention in the distal small bowel. However, this event contributed to patient management by clearly identifying the site of obstruction and can be used to guide surgical intervention, where an anastomotic ulcer is identified. 相似文献

Magnetic resonance imaging in ankylosing spondylitis 总被引:1,自引:0,他引:1
PURPOSE OF REVIEW: The past 18 months has seen considerable advances in the use of MRI for assessment of ankylosing spondylitis, to quantify active inflammation in the spine and sacroiliac joints which may not otherwise be detectable and to therefore measure change due to therapeutic interventions. RECENT FINDINGS: Characterization of the extension and morphology of inflammation in ankylosing spondylitis is now possible with MRI techniques. A number of randomized controlled trials of anti-tumour necrosis factor agents in ankylosing spondylitis have now been published showing regression of inflammatory lesions in the spine by MRI. Furthermore, the role of MRI for the early diagnosis of spondyloarthritis has become clearer. This review discusses the techniques used, the capabilities and the shortcomings of MRI in assessing ankylosing spondylitis patients. SUMMARY: MRI techniques have implications for early identification and intervention in patients with ankylosing spondylitis. 相似文献
