Spine abnormalities and damage in patients cured from Cushing's disease.

The skeletal system is a common target of glucocorticoids. Structural and functional impairment of skeletal system is a relevant cause of morbidity and disability in patients with Cushing's syndrome. Thirty-six patients long-term (3.9 +/- 0.5 yrs) cured from Cushing's disease (CD), 26 with adulthood-onset CD (AOCD) and 10 with childhood-onset CD (COCD) and 2 groups of controls, 24 age- and sex-matched patients with nonfunctioning pituitary adenomas (NFA) and 36 age- and sex-matched healthy subjects (HS), entered this open transversal controlled study to evaluate the prevalence of spine abnormalities and damage by standard radiography in subjects with a history of Cushing's syndrome. Symptoms and signs of backache were present in 86.1% CD patients (100% COCD and 80.8% AOCD), in 30.5% HS (chi2 = 20.6, p < 0.0001) and 37.5% NFA patients (chi2 = 13.2, p < 0.0001). The prevalence of trabecular bone rarefaction (chi2 = 6.5, p < 0.01 and chi2 = 4.5, p < 0.05), vertebral collapse (chi2 = 10.7, p < 0.01 and chi2 = 7.0, p < 0.01) and scoliosis (chi2 = 10.9, p < 0.01 and chi2 = 11.1, p < 0.01) resulted significantly increased in CD patients as compared both to HS and NFA patients. In CD patients, the number of collapsed vertebral bodies was significantly correlated to age of disease onset (r = -0.63, p < 0.0001), disease duration (r = 0.33, p < 0.05) and urinary free cortisol levels at disease diagnosis (r = 0.72, p < 0.0001). The prevalence of cortical bone sclerosis was significantly increased in AOCD than in HS (chi2 = 6.5, p < 0.01) and COCD (chi2 = 7.7, p < 0.01) whereas that of trabecular bone rarefaction was significantly higher in COCD patients than in HS (chi2 = 18.3, p < 0.0001), NFA (chi2 = 14.2, p < 0.0001) and AOCD patients (chi2 = 9.1, p < 0.01). Patients cured from CD have increased prevalence of spine damage, mostly when the disease developed before the completion of skeletal growth. Therefore, a periodical radiological follow-up of the skeleton and a specific treatment for the bone damage should be included in the management of patients with Cushing's syndrome.

[Urinary stress incontinence. Comparison of the Raz technique and the Bologna technique. Analysis of a series of 188 patients].

OBJECTIVE: Our purpose was to evaluate and compare the perioperative morbidity and the long-term results of the Raz colposuspension and the Bologna operation for the treatment of stress urinary incontinence in women. STUDY DESIGN: Data of 188 women who underwent either a Bologna operation (group 1) or a Raz colposuspension (group 2) for the treatment of stress urinary incontinence between January 1, 1987 and December 1, 1995 were analysed retrospectively regarding history, preoperative evaluation, associated surgical procedures, complications and cure and failure rate. POPULATION AND METHODS: 80 patients were treated with the Bologna operation and 108 with the Raz colposuspension. Patients with prior anti-incontinence surgery, and patients with a preoperative diagnosis of urge incontinence were excluded from the study. Success was defined both subjectively (complete absence of complaint of stress urinary incontinence) and objectively (no evidence of loss of urine on cough provocation during physical examination). Survival curves were generated in each group for time to event data: "time to recurrent stress incontinence" and compared by the logrank test. A multivariate analysis using a Cox proportional hazards regression model was performed to indentify possible outcome predictors. RESULTS: The success rate of group 1 was significantly higher than that of group 2 (p = 0.00001). The median of success was 51 months in group 1 and 21 months in group 2 (p = 0.00001). The incidence of intraoperative complications in each group (inadvertent cystostomy, hemorrhage) did not differ. The multivariate analyses using the Cox regression model showed that the most highly correlated variable with the surgical cure rate was the type of surgical anti-incontinence procedure adopted: Bologna or Raz (p = 0.00001) CONCLUSION: In our hands, the Bologna operation has a higher cure rate than the Raz colposuspension. For us, when treating patients with stress urinary incontinence by the vaginal route, the Bologna operation is indicated when sufficient anterior vaginal tissue is available to create vaginal bands.
