Fibrous dysplasia is an uncommon, benign disorder also known as fibrous mesothelioma. The cause of fibrous dysplasia is unknown. They represent 5% of all pleura neoplasms and in 80% of all cases arise from the visceral pleura. The epidemiology of the disease is reported equal between males and females around the age of 50. Fibrous dysplasia is usually asymptomatic, although several disease symptoms have been reported as hypoglycemia, pain and swelling may accompany the lesion, in advanced disease. Chemotherapy has not presented disease control; nevertheless, radiotherapy is efficient and indicated in residual disease. The disease progress is usually benign; however several disease manifestations have been reported. There are several molecular pathways, which are possible activated during the disease progress and therefore the disease expression changes throughout its course.KEY WORDS : Fibrinous tumor, molecular pathways, fibrous mesothelioma 相似文献

The efficacy of the docetaxel–carboplatin combination chemotherapy was studied in various phase II studies. Based on these
data we aimed to test the regimen in previously untreated patients with advanced advanced non-smoking lung cancer (NSCLC)
with docetaxel 80 mg/m2 a standard dose of carboplatin at AUC = 5, in an attempt to define the efficacy and tolerability of the combination in
an open-label phase II study. Patients with histologically confirmed advanced NSCLC stage IIIB and IV were candidates for
the present study. Docetaxel was administered at 80 mg/m2 over 1 h by intravenous (IV) infusion followed by carboplatin AUC = 5 in 30 min IV infusion, both on day 1, and recycled
every 21 days. Sixty patients received 263 courses of therapy in total; 231/263 (88%) were administered according to the planned
doses, and 48/60 (80%) patients received chemotherapy without decrement of the dose; 32/263 (12%) of the courses were administered
with a 10%–30% dose reduction. Complete responses (CR) were seen in 5 patients (8.3%) and partial responses (PR) in 16 patients
(26.7%) for an overall response rate of 35%. Median duration of response was 7.5 months [95% confidence interval (CI)-7.1–7.9],
time to progression (TIP) 11.5 months (95% CI-8.2–14.8), median overall survival (OS) 15.0 months (95% CI-10.8–19.2). One-year
survival was 61.7%. Toxicity was acceptable; it was calculated according to the administered cycles and was mainly neutropenia:
grade 3, 9% and grade 4, 2%; anemia: grade 3, 8%; nausea and vomiting: grade 3, 8%. The outpatient regimen of docetaxel–carboplatin
is effective with acceptable toxicity in patients with advanced NSCLC. 相似文献

Chronic corrosive strictures of the upper cervical esophagus and hypopharynx resulting from ingestion of caustic substances are a challenging surgical entity when repeated endoscopic dilatations fail to yield satisfactory results. Restoring the continuity of the upper digestive tract by esophageal substitution at healthy tissue margins not only compromises the integrity of the swallowing mechanism, but also often requires the performance of a tracheostomy in order to ensure avoidance of recurrent aspirations. We describe three cases of corrosive upper cervical esophageal strictures treated with intraoperative dilatation of the proximal hypopharyngeal stump and concurrent ‘stenting’ of the pharyngeal anastomosis with the conduit replacing the esophagus. All patients tolerated the procedure well. Avoidance of both impairment of deglutition and respiratory complications, as well as restoration of normal esophageal function, was successfully accomplished. 相似文献

Total hip arthroplasty in children with juvenile chronic arthritis: long-term results 总被引:1,自引:0,他引:1

From 1984 to 2002, 20 total hip arthroplasties in children with juvenile chronic arthritis were performed in the authors' department. All patients had polyarticular disease. Average age of patients was 15.8 (range 13-24) years. Early onset of the disease occurred at an average age of 7.3 (4-10) years. In six patients the physes were open at the time of surgery. All patients had complete loss of joint space and various combinations of subchondral sclerosis, flattening of the femoral head, and anterior inclination of the neck. All patients used crutches for walking and joint function was very restricted. All patients were operated on under general anesthesia. One of them was supported additionally with laryngeal mask because of cervical spine involvement. No intra- or postoperative complications occurred. Mobilization of the patients started immediately after surgery, followed by a special rehabilitation program. Follow-up examination was based on the Merle d'Aubigne et Postel scale as modified by Charnley. Patients were followed at 6 weeks and 3 months after surgery and thereafter every 6 months with clinical and radiologic examination. Average follow-up was 9.2 (2-20) years. All patients had no pain and full functional ability. Although total hip arthroplasty is technically difficult in this age, it should be performed in specialized centers because pain relief, decreased deformity, and improved quality of life can be achieved in most patients. The only disadvantage is wear of the prosthesis. 相似文献

In the last few years, renal artery stenting has gradually evolved into one of the most important therapeutic modalities in
the management of atherosclerotic renovascular disease. Stenting is nowadays preferred by a steadily increasing number of
physicians, not only because of its significant contribution to blood pressure control, but also because of its documented
ability to maintain, and even improve, renal function. At the same time, procedure-related morbidity and mortality rates are
extremely low, while recurrent stenosis rates have been repeatedly reported to be␣minimal. Percutaneous transluminal renal
angioplasty (PTRA) and stenting are nowadays considered by many physicians to be the treatment of choice for atherosclerotic
renovascular disease. 相似文献

The combination of radiotherapy and indomethacin for the prevention of heterotopic ossification (HO) in high-risk patients undergoing total hip arthroplasty (THA) has not been reported. The aim of the present study was to present the experience of our department with this combined therapeutic protocol. Fifty-four patients who underwent THA received a single dose of 7 Gy of postoperative radiotherapy and 75 mg of indomethacin for 15 days. Patients were analyzed for clinical and radiographical evidence of HO development at 1 year postoperatively. The overall radiographical incidence of HO was 20.4% (95% CI 10.6–33.5%), while only 1 patient with clinically significant HO was seen. Patients with secondary arthritis due to congenital hip disease had a statistically significantly higher incidence of HO compared with those with osteoarthrosis. The clinical assessment with the Merle d’Aubigné score showed that patients with radiographic documentation of HO had a lower mean score compared with those with no evidence of HO. No treatment-related side effects were seen. Combined radiotherapy and indomethacin was effective in preventing heterotopic ossification after total hip arthroplasty. The evaluation of this efficacy compared with radiotherapy or NSAIDs alone should be the future target of larger randomized designs.
Résumé L’association de radiothérapie et d’indométhacine pour la prévention des ossifications hétérotypiques (HO), chez les patients à haut risque, devant bénéficier d’une prothèse totale de hanche (THA) n’a jamais été rapportée. Le but de cette étude est de présenter cette expérience. Cinquante-quatre patients devant bénéficier d’une prothèse totale de hanche ont reçu une dose unique de 7 Gy en post-opératoire de radiothérapie et 75 mg d’indométhacine pendant 15 jours. Sept séries de patients ont été analysés cliniquement, radiographiquement à la recherche d’ossifications hétérotypiques au décours de la première année post-opératoire. L’incidence totale des ossifications hétérotypiques a été de 20,4% (95% CI 10.6–33.5%), un seul patient présentant une ossification gênante sur le plan clinique. Les patients présentant une coxarthrose secondaire à une luxation congénitale de hanche ont, significativement plus d’ossifications hétérotypiques que les patients présentant une coxarthrose banale. Le score de Merle d’Aubigné est significativement plus bas chez les patients présentant des ossifications hétérotypiques avec symptomatologie clinique en comparaison de ceux ne présentant que des signes radiographiques. Il n’y a aucune complication due au traitement. La combinaison radiothérapie indométhacine semble effective dans la prévention des ossifications hétérotypiques après prothèse totale de hanche. L’évaluation de son efficacité en comparaison à une radiothérapie ou à un traitement anti-inflammatoire isolé doit faire l’objet d’une plus longue étude randomisée.相似文献

OBJECTIVE: To assess whether outpatient hysteroscopy using the 'no-touch' technique confers any advantages in terms of patient discomfort over the traditional technique. DESIGN: Prospective randomised controlled study. SETTING: Outpatient hysteroscopy clinic in a large university undergraduate teaching hospital. POPULATION: All women referred for outpatient hysteroscopy in a 12-month period. INTERVENTIONS: Women were randomised to undergo either traditional saline hysteroscopy requiring the use of a speculum and tenaculum, or a 'no-touch' vaginoscopic hysteroscopy which does not require a speculum or tenaculum. Each group was further subdivided to have hysteroscopy with either a 2.9-mm or 4-mm hysteroscope. Patients were asked to complete pre- and postprocedure questionnaires ranking pain scores. MAIN OUTCOME MEASURES: The relative success of each of these techniques, requirement for local anaesthetic and pain scores at different times during the hysteroscopy were recorded at the end of the procedure. The time taken to carry out each procedure was also measured. RESULTS: One hundred and twenty women were recruited in this study: 60 were randomised to traditional hysteroscopy and 60 to 'no-touch' hysteroscopy. The overall success rate for hysteroscopy was 99%. There was no significant difference in the requirement for local anaesthetic between the two groups, but those who underwent 'no-touch' hysteroscopy with a 2.9-mm hysteroscope had the lowest requirement of local anaesthetic (10% compared with 27% in the no-touch hysteroscopy with a 4-mm hysteroscope group). The time taken to perform hysteroscopy and biopsy was significantly shorter with 'no-touch' hysteroscopy (5.9 vs 7.8 min; difference 1.9, 95% CI 0.7-3.1). There were no differences in pain scores between the groups at different times during hysteroscopy. CONCLUSIONS: 'No-touch' or vaginoscopic hysteroscopy is significantly faster to perform than the traditional technique. Although there was no difference in pain scores between the two techniques, local anaesthetic requirements were least in those who underwent 'no-touch' hysteroscopy with a narrow bore hysteroscope. 相似文献

Purpose: This is a phase II study where a novel chemotherapy combination was tested in pre-treated breast cancer patients: docetaxel and irinotecan have already been established as agents for breast and colorectal cancer, respectively. Methods: Forty-eight (median age 54 years, range 26–77 year) patients, all evaluable, were enrolled. All patients had been pre-treated with anthracycline-combined chemotherapy, 30 of whom were also treated with paclitaxel and 2 with docetaxel. World Health Organization (WHO) performance status was 0–2. The dominant metastasis was in the liver (54.17%), in the lungs (27.08%), in soft tissues (12.50%) and in the skeleton (6.25%). Treatment involved irinotecan infusion 200 mg/m2 for 90 min and docetaxel infusion 80 mg/m2 for 90 min, repeated once every 3 weeks. Results: Twenty-five (52.08%, 95% confidence interval [CI] 37.95–66.21) patients showed responses: 3 complete (6.25%, 95% CI 0–13.05) and 22 (45.83%, 95% CI 31.74–59.92) partial; the most responsive metastases were observed at the liver site (53.85%). Grade 3 and 4 neutropenia was observed in 18 patients (37.50%); 14 (29.17%) patients developed anaemia and three (6.25%), thrombocytopenia. Concerning non-haematologic toxicity, alopecia and fatigue were common; grade 3 diarrhea was observed in only one (2.08%) patient. Conclusion: The irinotecan-docetaxel combination produces quite a high response rate in pre-treated advanced breast cancer patients. 相似文献

OBJECTIVE: To evaluate whether the C677T polymorphism of the methylenetetrahydofolate reductase (MTHFR) gene is consistently associated with hypertension in pregnancy. DESIGN: Meta-analysis of studies comparing women with and without hypertension in pregnancy for the C677T MTHFR polymorphism. METHODS: Studies were identified with MEDLINE and EMBASE searches complemented with perusal of bibliographies of retrieved articles and communication with investigators. Between-study heterogeneity was estimated and data were combined with random effects models. Sensitivity analyses examined the effect of population and disease characteristics. Bias diagnostics evaluated the evolution of the postulated genetic effect over time and the potential for publication bias. RESULTS: Across 23 comparisons (3169 hypertensive women, 3044 controls), having the T allele (TT or CT) increased the odds of hypertensive disease of pregnancy by 1.21-fold (95% confidence interval, 1.01-1.44), but there was large between-study heterogeneity (P = 0.003). The results were similar and heterogeneity persisted when sensitivity analyses were limited to studies of Caucasian populations, or those of patients with significant proteinuria. While patients with diastolic hypertension > or = 110 mmHg showed an odds ratio of 1.41 (95% confidence interval, 1.03-1.73), no association was seen in patients with less severe diastolic hypertension (odds ratio, 1.00; 95% confidence interval, 0.61-1.65). Early published studies tended to show stronger associations than the subsequent studies. CONCLUSIONS: While bias cannot be excluded, the meta-analysis suggests that the T allele may increase the risk of severe diastolic hypertension during pregnancy. 相似文献
