STUDY AIM: To identify prognostic factors in advanced pancreatic cancer and to define a predictive score. PATIENTS AND METHOD: One hundred and sixty six patients were included in this multicentre study. Seventeen covariables were prospectively collected for each patient. Covariables associated with survival (p < 0.10) were analysed by a stepwise Cox model. RESULTS: Four prognostic factors were selected on multivariate analysis: pain (RR 1.5; CI: 1.1-2.0), ascites (RR 1.7; CI: 1.0-2.9), weight loss > 10 kg (RR 1.4; CI: 1.0-2.0), and metastases (RR 2.3: CI: 1.6-3.2). A score was defined by attributing a value of one for pain, ascites and weight loss, and two for metastases. Patients with a score > 2 had a median survival of 2 months (SE: 0.5), and patients with a score < or = 2 had a median survival of 6 months (SE: 0.6) (Logrank p < 0.0001). CONCLUSION: The proposed score may be helpful in therapeutic decisions concerning surgery, palliative chemotherapy and/or radiotherapy. However, this score must be validated on an independent series of patients.  相似文献

The exploration of ferroelectric hybrid materials is highly appealing due to their great technological significance. They have the potential to conserve power and amazing applications in information technology. In line with this, we herein report the development of a [(C4H9)4N]3Bi2Cl9 tetra-alkyl hybrid compound that exhibits ferroelectric properties. The phase purity was confirmed by Rietveld refinement of the X-ray powder diffraction pattern. It crystallizes, at room temperature, in the monoclinic system with the P21/n space group. The outcome of temperature dependence of the dielectric constant proved that this compound is ferroelectric below approximately 238 K. The dielectric constants have been fitted using the modified Curie–Weiss law and the estimated γ values are close to 1. This confirms classical ferroelectric behavior. Raman spectroscopy is efficiently utilized to manifest the origin of the ferroelectricity, which is ascribed to the dynamic motion of cations as well as distortion of the anions. Moreover, the analysis of the wavenumbers and the half-width for δs(Cl–Bi–Cl) and ω(CH2) modes, based on the order–disorder model, allowed us to obtain the thermal coefficient and activation energy near the para-ferroelectric phase transition.

Pyogenic arthritis of the atlantoaxial joint is scarce. It can lead to several complications, such as spinal cord compression and cerebral vein thrombosis. A 51‐year‐old man presented with a twenty‐day history of inflammatory neck pain. Physical examination revealed paravertebral muscle contracture, restricted neck movement, and fever. Spine magnetic resonance imaging (MRI) showed synovitis of atlanto‐odontoid joint, anterior epidural collection, and cerebral vein thrombosis. Transthoracic echocardiography was unremarkable. The patient was successfully treated with anti‐staphylococcal antibiotic treatment for 12 weeks associated with immobilization of the cervical spine. MRI performed one month after the initiation of the treatment showed disappearance of the epidural collection. The diagnosis of septic arthritis of the atlantoaxial joint should be considered in a patient with inflammatory neck pain. MRI findings are relevant in making the diagnosis of a septic atlanto‐odontoid joint. Conservative treatment, including antibiotic and neck immobilization, can be sufficient for the treatment of pyogenic arthritis of the atlantoaxial joint. Cerebral vein thrombosis is a rare complication due to septic arthritis of the atlantoaxial joint.  相似文献

The simultaneous occurrence of bronchopleural fistula (BPF) and esophagopleural fistula (EPF) after pneumonectomy is very rare. We describe a 60-year-old man who developed empyema associated with bronchopleural fistula as a complication of a right pneumonectomy. Initial chest tube drainage and antibiotic therapy were ineffective. Five months later ingested food particles appeared in the drainage fluid. Esophagoscopy revealed an esophageal fistula of 10 mm in diameter. After nutritional support by feeding jejunostomy both BPF and EPF were repaired by subscapular muscle myoplasty and extensive thoracoplasty through a right thoracotomy. Endoscopic examination performed 1 month after surgery showed complete closure of both fistulas and 9 months after surgery the patient was eating and gaining weight. The patient's death was due to aspiration pneumonia of another origin.  相似文献

The sexually transmitted infections pose a real public health problem, mainly in developing countries. In Tunisia, the epidemiological state is not precise. The objective of our study was to determine the sociological, epidemiological and bacteriological characteristics of gonococcal urethritis in the area of Sfax. The study was performed on all patients attending at the CNSS of Sfax for urethritis for 5 years, from 1996 to 2000. A urethral swab was carried out for each patient with a classic bacteriological exam. 256 cases were collected. The mean age was 29.7 years. 74.3% were workers. The direct exam was positive in 51.2% of cases and the culture enabled us to isolate 72 strains, of which 15.5% were productive of beta-lactamase and 23.9% were resistant to tetracyclin. There was no resistance to pristinamycin, ofloxacin nor spectinomycin.  相似文献

Orbital hydatidosis is uncommon, accounting for 1 to 2% of all localizations. It is caused by Echinococcus granulosis, a dog parasite tapeworm. We report an intra-orbital hydatid cyst observed in a five-year-old boy, presenting the main features of this unusual localization. Hydatid cyst should be evoked in case of tumorous exophthalmia in young patients, especially in children having lived in endemic zones. The preoperative diagnosis is based on clinical findings and ultrasonographic, computed tomographic and magnetic resonance imaging findings. The fronto-orbital approach is most commonly used for treatment. Infectious and functional prognosis depends on early surgery.  相似文献
