PURPOSE: We estimated the prevalence of erectile dysfunction in patients with type 2 diabetes and identified subgroups of patients in which the interaction among clinical, psychological and sociodemographic characteristics determined an increased likelihood of erectile dysfunction. MATERIALS AND METHODS: The presence of erectile dysfunction was based on patient self-reporting. Clinical information was collected by participating physicians. The severity of depressive symptoms was investigated using the Center for Epidemiological Studies Depression scale. To evaluate interactions among the variables investigated and identify distinct, homogeneous subgroups of patients with different odds ratios for erectile dysfunction a tree growing technique was used. RESULTS: In the 1,460 patients studied the prevalence of severe and mild-moderate erectile dysfunction was 34% and 24%, respectively. While severe erectile dysfunction was mainly related to the severity of diabetes, mild-moderate dysfunction was independent of clinical variables and only associated with the severity of depressive symptoms. The tree growing technique led to the identification of 6 classes characterized by a marked difference in the prevalence of severe erectile dysfunction of between 19% and 65%. Patients on diet alone showed the lowest prevalence of erectile dysfunction and were considered the reference category, while patients treated with insulin who had neuropathy represented the subgroup with the highest likelihood of erectile dysfunction (OR = 7.2, 95% CI 3.9 to 13.2). In patients treated with oral agents the odds ratio for erectile dysfunction was 2.7 (95% CI 1.8 to 3.9) for those with severe depressive symptoms and 1.9 (95% CI 1.3 to 2.7) for current/former smokers with low depressive symptoms. Patient age, retinopathy and cardiac-cerebrovascular disease were globally predictive variables associated with an increased likelihood of erectile dysfunction. CONCLUSIONS: Our data illustrate the interplay of clinical and psychological factors in determining the risk of erectile dysfunction in type 2 diabetes and can help identify those for whom much greater attention is needed to detect erectile problems. 相似文献

Percutaneous osteoplasty as a treatment for painful malignant bone lesions of the pelvis and femur 总被引:6,自引:0,他引:6
Hierholzer J Anselmetti G Fuchs H Depriester C Koch K Pappert D 《Journal of vascular and interventional radiology : JVIR》2003,14(6):773-777
The purposes of this report are to describe percutaneous osteoplasty as a highly effective minimally invasive procedure to treat painful malignant bone lesions of the pelvis, ilium, and femur and to discuss the relevant literature. Five patients with histologically proven metastases to the pelvis, ilium, or femur were treated by percutaneous injection of liquid bone cement as an attempt to control severe bone pain. After percutaneous osteoplasty, all five patients experienced immediate and substantial pain relief and did not require pain medication for the duration of follow-up. No clinically significant complications occurred. Whereas percutaneous osteoplasty of the spine (vertebroplasty) is well-described and widely accepted to treat pain caused by benign or malignant vertebral body diseases, osteoplasty of bones outside the spine is less known. The immediate good clinical results observed in our small patient group should encourage more widespread application of this palliative treatment. 相似文献

Late complication of open inguinal hernia repair: Small bowel obstruction caused by intraperitoneal mesh migration 总被引:3,自引:3,他引:0
We describe a case of small bowel obstruction due to prosthetic mesh migration. A 67-year-old male, who had undergone prosthetic
repair of inguinal hernia 3 years before, was admitted for a mechanical small bowel obstruction. Laparotomy revealed the penultimate
ileal loop choked by an adhesion drawing it towards a polypropylene mesh, firmly attached to the parietal peritoneum of the
inguinal region. The intestinal loop was released; the mesh was embedded deep with continuous whip suture after folding the
parietal peritoneum. The patient was dismissed on the 11th postoperative day surgically healed. The "tension-free" technique
is undoubtedly the gold standard for hernia repair. However, it is not free of complications, mostly due to technical errors,
of which the surgeon must be aware, both when he is responsible for correcting defects in the wall, as well as when he has
to face an occlusion in a patient who has undergone plastic surgery for inguinal hernia. 相似文献

OBJECTIVES: We performed this observational study to validate the three components of a new venous severity scoring (VSS) system, ie, venous clinical severity score (VCSS), venous segmental disease score (VSDS), and venous disability score (VDS), and to evaluate VCSS, VDS, and CEAP clinical class and score in quantifying outcome of varicose vein surgery.Patients and methods The study included 45 patients who underwent superficial venous surgery in 48 legs with primary varicose veins. Venous color duplex scanning, clinical examination, and a questionnaire were used preoperatively and at 6 weeks and 6 months postoperatively to assign VSS and CEAP clinical class and score. RESULTS: CEAP clinical score, VCSS, and VDS demonstrated a linear association with CEAP clinical class (P <.001, P <.001, P =.002, respectively). Good correlation among all severity scores was found, particularly between CEAP clinical score and VCSS (r = 0.94; P <.001). CEAP clinical score was also highly correlated with CEAP clinical class (r = 0.84; P <.001) and VDS (r = 0.70; P <.001). Similarly, VCSS correlated with CEAP clinical class (r = 0.83; P <.001) and also VDS (r = 0.72; P <.001). The anatomic severity marker VSDS demonstrated a weak correlation with clinical severity indicators VCSS (r = 0.29; P =.048) and VDS (r = 0.31; P =.03) but not with age, gender, or CEAP clinical class and score. Six months after surgery the median (interquartile range) percent change in VCSS (73%; range, 50%-100%) and CEAP clinical score (70%; range, 50%-100%) were both significantly greater (P <.001) than the corresponding change in CEAP clinical class (17%; range, 0%-50%). In legs with high VDS at baseline, median (interquartile range) percent change in VDS was 100% (range, 50%-100%), significantly greater (P <.001) than the corresponding change in CEAP clinical class (0%; range, 0%-17%). CONCLUSIONS: Venous severity scores are significantly higher in advanced venous disease, demonstrating correlation with anatomic extent. Both venous clinical severity scores, VCSS and CEAP clinical score, are equally sensitive and significantly better for measuring changes in response to superficial venous surgery than is the already in use CEAP clinical class. VDS demonstrated comparable and even better performance. Although the assignment of CEAP clinical class might be adequate for daily clinical purposes, venous severity scoring systems should be used in clinical studies to quantify venous outcome. 相似文献

PURPOSE: The high mortality rate for lung cancer is likely to be reduced by the development of a panel of sensitive biological markers able to identify early-stage lung cancers or subjects at high risk. The aim of this study was to establish the frequency of K-ras and p53 mutations and p16(INK4A), RASSF1A, and NORE1A hypermethylation in sputum of a large cohort of cancer-free heavy smokers and to assess whether these markers are suitable for a routine use in the clinical practice for the early diagnosis of pulmonary cancer. EXPERIMENTAL DESIGN: Sputum samples were collected from 820 heavy smokers. Inclusion criteria consisted of radiologic and cytologic absence of pulmonary lesions, age at least 60 years, male gender, and a smoking history of at least 20 pack-years. RESULTS: The analysis identified 56 individuals (6.9%) with one molecular alteration. p53 mutation and p16(INK4A), RASSF1A, and NORE1A methylation frequencies were 1.9%, 5.1%, 0.8%, and 1.0%, respectively; no K-ras mutations were found. One patient with p53 mutations was diagnosed with an early-stage lung cancer after 3-years of follow-up. The molecular analysis of bronchoscopy samples confirmed in half of the cases alterations present in sputum without revealing additional molecular changes. CONCLUSIONS: Genetic and epigenetic abnormalities can be detected in cancer-free heavy smokers. Although the predictive value of the cancer risk is still to be established as it requires not less than 5 years of follow-up, p53 and p16(INK4A) are more promising candidates than K-ras, RASSF1A, and NORE1A for the pulmonary molecular screening of heavy smokers healthy individuals. 相似文献

The lipid content of fetal cells was determined in 45 samples of human amniotic fluid. Free and total cholesterol were estimated using a gas chromatographic method, and glycerides were evaluated through the enzymatic assay of their glycerol content. The number of orange cells was estimated after staining with Nile Blue sulphate.
The chemically measured lipid content appeared closely related to the number of orange cells. Total cholesterol and glycerides showed a sharp increase after the 37th week of pregnancy. These tests seem to assess fetal maturity successfully, providing a further useful aid in the management of high-risk pregnancies.
The chemical determination of cell-associated lipids showed good accuracy and reliability and, when compared with the histochemical method, allowed a better evaluation of progressive lipid accumulation within the amniotic fluid cells. 相似文献
