Assessment of symptoms should be one of the main outcome measures in dyspepsia clinical trials. This requires a reliable, valid and responsive questionnaire that measures the frequency and severity of dyspeptic symptoms. The Short-Form Leeds Dyspepsia Questionnaire (SF-LDQ) has been proven to fulfil these criteria in its original version in the English language. The aim of the study was to assess the internal consistency, reliability, validity and responsiveness of the Italian version of the SF-LDQ in primary and secondary care. Unselected primary and secondary care patients completed the Italian version of the SF-LDQ. Test–retest reliability was assessed after 2 days. Validity was measured by comparison with diagnosis made by physicians. Responsiveness was determined before and after treatment for endoscopically proven disease. The SF-LDQ was administered to 311 patients in primary care and 179 in secondary care patients. Internal consistency, as judged by the Cronbach’s α, was 0.90. Pearson’s correlation coefficient for test–retest reliability was 0.92. The SF-LDQ had a sensitivity of 80% and a specificity of 82%. A highly significant response to change was also observed (p = 0.001). The Italian SF-LDQ is a reliable, valid and responsive self-completed outcome measure for quantifying the frequency and severity of dyspeptic symptoms.  相似文献

Gastroesophageal reflux disease is the most common gastrointestinal diagnosis recorded during visits to outpatient clinics. The spectrum of injury includes esophagitis, stricture, the development of columnar metaplasia in place of the normal squamous epithelium (Barrett’s esophagus), and adenocarcinoma. Barrett’s esophagus is a premalignant lesion detected in the majority of patients with esophageal and gastroesophageal adenocarcinoma. The incidence of these cancers has been increasing in the United States and they are associated with a low rate of survival (5-year survival rate, 15–20%). When symptoms of gastroesophageal reflux disease are typical and the patient responds to therapy, no diagnostic tests are necessary to verify the diagnosis. Endoscopy is the primary test in patients whose condition is resistant to empirical therapy but its yield in this setting is low because of the poor correlation between symptoms attributed to the condition and endoscopic features of the disease. Clinical experience suggests that lifestyle modifications may be beneficial for gastroesophageal reflux disease although trials of the clinical efficacy of dietary or behavioral changes are lacking. Abundant data from randomized trials show benefits of inhibiting gastric acid secretion and suggest that proton-pump inhibitors are superior to H2-blockers and that both are superior to placebo. In patients with Barrett’s esophagus, antireflux interventions are intended to control symptoms of reflux and promote healing of the esophageal mucosa. If a patient has symptoms refractory to proton-pump inhibitors or cannot tolerate such therapy, antireflux surgery, most commonly Nissen fundoplication, may be an alternative management approach. In patients with high-grade dysplasia, endoscopic therapies or surgical resection must be considered.  相似文献

It is known that BRCA genes play central roles in hereditary breast and ovarian cancers. BRCA1 mutation carriers face a cumulative lifetime risk of ovarian and breast cancer development. We report on a case of a strong family prevalence of BRCA1 linked malignancies as an immense psychological encumbrance and reason of demand for radical prophylactic risk decreasing surgeries in a 29 year-old healthy woman with proved 3889delAG BRCA1 gene mutation on exon 11, codon 1265 in effort to prevent possible malignant changes in the ovaries and the breast. Problems regarding the management of asymptomatic BRCA mutation carriers, time and impact of early prophylactic surgery in young women are discussed with a review of recent literature.  相似文献

The aim of the study was to show the relationship between phacoemulsification and extracapsular cataract extraction at University Department of Ophthalmology, Split University Hospital Center (assessing the length of postoperative hospital stay and postoperative visual acuity), during the 1997-2009 period. We also wanted to explore the tendency of using different types of intraocular lenses. The study was designed as a retrospective analysis of operative records. Data were collected on all patients operated for cataract at our Department during the study period. We compared the mean duration of postoperative hospital stay and mean postoperative visual acuity between 1997/1998 (more than 90% were treated with ECCE technique) and 2007/2008 (more than 90% were treated with PHACO technique). Information was also collected on the type of lenses implanted. The rate of cataract extraction by phacoemulsification was less than 10% in 1997/1998, then progressively rising to reach 99.2% in 2009. The mean hospital stay was 5.73 (range 2-19) days in 1997/1998 as compared with 1.99 (range 0.02-1) days in 2007/2008. The mean uncorrected postoperative visual acuity was 0.71 (range 0.01-1.0) in 2007/2008. In conclusion, the number of cataract patients operated on by the phacoemulsification technique progressively and significantly increased during the 1997-2009 period, confirming the method as the most acceptable and less traumatic technique that is applicable in most of cataract patients.  相似文献

The results of experimental studies have indicated the pleiotropic effects of statins in organism, e.g. the influence on cell cycle, apoptosis or angiogenesis. In this study, the effects of simvastatin on selected parameters of apoptosis and proliferation in chemocarcinogen-induced mammary tumorigenesis in female rats were determined. Simvastatin was administered dietary at a dose of 18 mg/kg and highly effective dose of 180 mg/kg the entire experiment (18 weeks). At autopsy mammary tumors were removed and prepared for immunohistochemical and histomorphological analysis. In treated animals (simvastatin 180 mg/kg), significant decrease by 12% in Bcl-2 protein expression and non-significant decrease by 27% of Ki67 protein expression in tumor cells compared to tumor cells in control animals were observed after semiquantitative evaluation. Morphometrical analysis has shown significant proapototic shift in Bcl-2/Bax ratio in tumor cells. In high grade control carcinoma cells, the expression of Ki67 increased by 37% (non-significantly) in comparison with control low grade carcinomas. A histomorphological analysis of malignant tumors has revealed a shift from high grade to low grade carcinomas after simvastatin treatment. The noticeable decrease of mammary tumor frequency and incidence in rats after simvastatin treatment was accompanied with antiapoptotic Blc-2 protein decrease and proapoptotic Bax protein increase in this experiment.  相似文献

The antiapoptotic protein survivin is widely expressed in most human cancers, including carcinomas of the breast. It is rarely detected in corresponding normal adult tissues. Therefore, survivin comes into the limelight as a promising diagnostic biomarker and prognostic parameter. Immunohistochemically, we examined the expression of this protein in 126 cases of ductal breast carcinoma to determine the association with clinicomorphological parameters such as age of patients, grade, stage and size of the primary tumor, lymph node metastasis, vascular invasion as well as estrogen and progesterone status. In each section, the subcellular location of survivin antigen, the intensity of staining and the percentage of labeled cells were assessed. Overall, survivin was expressed in 111 cases (88.1%). The statistical analysis revealed a significant correlation between the nuclear location of survivin and tumor grade 3. Furthermore, a significant relation was also found between vascular invasion and nuclear and combined nuclear and cytoplasmic survivin expression, together with a higher intensity of immunoreaction. However, no significant correlations were shown with other clinicomorphological parameters, such as stage and size of the tumor, lymph node metastasis, estrogen and progesterone receptors and age. Our findings revealed that survivin was frequently overexpressed in carcinoma cells, where it was present in different subcellular compartments. The nuclear positivity of survivin or combined nuclear and cytoplasmic expression was shown to be a poor prognostic parameter in ductal breast carcinoma.  相似文献

Carcinosarcoma of the uterus with melanocytic differentiation   总被引:1,自引:0,他引:1  
Carcinosarcomas (CSs) are rare biphasic neoplasms of the female genital tract, with the presence of malignant epithelial and mesenchymal components. The occurrence of non-epithelial or non-mesenchymal differentiations in CSs is extremely rare. A case of a 54-year-old woman with a history of treatment for breast carcinoma is reported. The patient presented with a uterine tumor showing histological, immunohistochemical, and ultrastructural features of an extremely rare CS, with signs of melanocytic differentiation. The lesion was a 7.0 x 5.6 cm polypoid tumor mass arising from the endometrium and metastasizing in the abdominal cavity as a malignant melanoma - the most aggressive component of CS. Despite adjuvant chemotherapy, she died 8 months after the initial diagnosis due to the metastatic spread of CS. In line with current knowledge, we assess the melanocytic differentiation as one of a hypothetic differential line with the ability of multidirectional stem cell differentiation. We discuss a possible pathogenesis of this lesion and the role of tamoxifen in the tumor development as well. To the best of our knowledge, only one case of uterine CS with melanocytic differentiation has been reported in the English literature.  相似文献
