The aim of the present study was to evaluate the clinical performance of the CA 15-3 assay on Elecsys systems in an international multicenter study (11 centers). A total of 1326 single samples (272 apparently healthy individuals, 34 pregnant women, 308 benign diseases, 273 cancers other than breast, 439 breast cancer) and 538 serial samples of 98 breast cancer patients during follow-up were analyzed. 95% of values in healthy individuals were below 25 kU/L, and 88% in benign breast diseases, respectively. In malignant breast disease at primary diagnosis the value distribution of Elecsys CA 15-3, sensitivity at 95% specificity, as well as the areas under the curve in ROC analysis were clearly correlated to tumor stages: UICC I to IV 88 to 25% of values < 25 kU/L, sensitivity 7 to 78%, areas under the curve 0.53 to 0.94. During follow-up, sensitivity/specificity for detection of recurrences were 90%/71%. In metastatic disease clinical progression/response to therapy were indicated in 91%/78% of patients at a specificity of 92%/78%. The findings indicate that the Elecsys CA 15-3 assay is very suitable in routine work for detection of recurrences as well as for therapy control in metastatic breast cancer. 相似文献

The prosperity of brain parenchyma during aging depends on the preservation of cerebral blood flow (CBF) parameters. We have analysed ultrasonographic measurements of peak systolic (PSV) and end diastolic velocities (EDV) along with pulsatility (PI) and resistance indexes (RI) in common (CCA), internal (ICA) and external carotid artery (ECA) (N=199) and in vertebral arteries (VA) (N=200) in patients without any signs of stenosis. In two other cohorts patients with internal carotid artery stenosis (N=231) and patients prior to and after therapeutic recanalization (N=81) were evaluated in the same parameters. Results: in the range of 21-92 years PSV in CCA decreases by 7 mm/s/year, while in ICA only by 2.31 mm/s/year. The decrease of EDV in carotid arteries occurs between 1.72 and 2.28 mm/s/year. PSV in VA drops down by 0.91 mm/s/year, EDV by 0.86 mm/s/year. PI and RI increase with age in all vessels, but not significantly. Stenotic ICAs are associated with increased PSV in the range of 0.7-2.9 m/s, but also with an increasing PSV variability along the growing stenosis in individual patients. In all degrees of stenoses some patients preserve normal velocities. In average the increment for each 10% of the stenosis below 50% makes 8 cm/s, while above 50% it makes already 50 cm/s. In persons with bilateral stenoses the increment with growing stenosis is steeper. The restoration of normal ICA lumen by means of carotid endarterectomy or by angioplasty with stenting results in an average drop by 1.23 m/s in PSV and by 0.4 m/s in EDV. We have investigated the ophthalmic artery and other substitution supplies and deduce, that the remarkable differences in blood flow velocity reactions to a compromised carotid lumen depend on the formation of collaterals in mutual interplay with peripheral resistance. 相似文献

This review summarizes the modern early diagnosis and acute phase treatment of acute stroke. The guidelines for treatment of acute ischemic stroke underwent major changes in 2015 and endovascular therapy (catheter-based mechanical thrombectomy with a stent retriever) became the class IA indication for patients presenting within less than 6 h from symptom onset who have proven occlusion of large intracerebral artery in anterior circulation. Acute stroke care organization should enable to perform effective revascularization therapy as soon as possible after the initial brain imaging whenever this examination provides indication for the procedure. 相似文献

OBJECTIVES: To investigate whether ultrasound-guided vacuum biopsy (VB) with curative intent is suitable for the complete extirpation of selected sonographically detectable benign lesions of the breast, and to establish the limitations of the method with regard to lesion size and complications, the extent of scar formation and the prognostic value. METHODS: One hundred and nine patients underwent hand-held, ultrasound-guided VB (8G or 11G needle) between June 2000 and September 2003. Of these, 45 (41%) women underwent ultrasound-guided extirpation of 46 lesions, and 42 women with 43 lesions were followed up clinically and sonographically for an average of 5.9 months. The complete extirpation rate, residual lesions, and patient satisfaction with the intervention were evaluated. RESULTS: Removal of all sonographic evidence of lesions (median diameter, 13 mm) was achieved in 86% of cases (8G needle, 80%; 11G needle, 89%). 19% of the patients had suspected scar formation at the biopsy site. A palpable lesion in the breast could be removed by VB in 90% of cases. None of the patients developed infections and there were no hemorrhages requiring intervention, or damage to the skin or chest wall. A total of 95% of the patients stated that they would prefer this approach to open excision for possible future intervention. CONCLUSIONS: VB is an ambulatory procedure associated with a low degree of pain. It has a high degree of patient acceptance and, as a minimally invasive biopsy technique for benign lesions, is a good alternative to open excision. The rate of complications is low and is similar to that observed with conventional microbiopsy. 相似文献

Zusammenfassung Nach einleitender Schilderung der pathologischen Anatomie und der Ätiologie der Pachymeningitis cervicalis hypertrophica wurde ein eigener Fall dieses Krankheit bei einer 55jährigen Frau besprochen. Der Prozeß war hier über dar gesamte Rückenmark lokalisiert. Als Besonderheit fand sich eine hochgradige Auflösung der gewohnten Rückenmarksstrukturen durch den entzündlichen Prozeß. Ursächlich war der Fall mit einer in den jüngeren Lebensjahren durchgemachten, ätiologisch leider nicht ganz klaren Meningitis verknüpft.Bei der Besprechung des Falles wurde auf die vonO. Fischer gewählte Bezeichnung Trimeningitis chronica hyperplastica hingewiesen, die das Wesen der Krankheit und seine Lokalisation unseres Erachtens zutreffender charakterisiert.Die vergleichende pathologische Anatomie des Leidens wurde kurz erwähnt.

Summary After review of the pathological anatomy and the aetiology of pachymeningitis cervicalis hypertrophica a case of a 55-year-old woman is reported.The process was extended over almost the total spinal cord. A severe dissolution of normal structures of the spinal cord caused by the inflammatory process was found. Causal connection with a juvenile meningitis of unclear aetiology was supposed.In the discussion the term of Trimeningitis chronica hyperplastica byO. Fischer is proposed, which characterizes the nature and localisation rather appropriately.The comparative pathological anatomy of the disease in question is dealt with briefly.

ObjectivesThis study analyzed the learning curve effect when a new stroke thrombectomy program was initiated in a cardiac cath lab in close cooperation with neurologists and radiologists.BackgroundMechanical thrombectomy has proven to be the best treatment option for ischemic stroke patients, but this method is not widely available.MethodsAn endovascular treatment program for acute ischemic strokes was established in the cardiac cath lab of a tertiary university hospital in 2012. The decision to perform catheter-based thrombectomy was made by a neurologist and was based on acute stroke clinical symptoms and computed tomography angiographic findings. Patients with a large vessel occlusion of either anterior or posterior circulation were enrolled. The primary endpoint was the functional neurological outcome (Modified Rankin Scale [mRS] score) of the patient at 3 months. A total of 333 patients were enrolled between October 2012 and December 2019.ResultsThe clinical (mRS) outcomes did not vary significantly across years 2012 to 2019 (mRS 0 to 2 was achieved in 47.9% of patients). Symptomatic intracerebral hemorrhage occurred in 19 patients (5.7%). Embolization in a new vascular territory occurred in 6 patients (1.8%).ConclusionsWhen a catheter-based thrombectomy program was initiated in an experienced cardiac cath lab in close cooperation between cardiologists, neurologists, and radiologists, outcomes were comparable to those of neuroradiology centers. The desired clinical results were achieved from the onset of the program, without any signs of a learning curve effect. These findings support the potential role of interventional cardiac cath labs in the treatment of acute stroke in regions where this therapy is not readily available due to the lack of neurointerventionalists. 相似文献

Purpose: The vacuum biopsy of the breast under sonographic guidance (VB) was introduced in Germany in the year 2000 and the first consensus recommendations were published by Krainick-Strobel et al. in 2005. Since then, many clinical studies on this technique have been published. The purpose of this publication is to update the consensus recommendations from 2005 regarding the latest literature. Materials and Methods: The consensus statements were the result of two preliminary meetings after the review of the latest literature by members of the Minimally Invasive Breast Intervention Study Group from the German Society of Senology. The final consensus text was review by all members of the working group. The statements listed under results obtained complete acceptance (consensus 100 %). Results: The consensus recommendations describe the indications, investigator qualifications, technical requirements, documentation, quality assurance and follow-up intervals regarding the latest literature. Conclusion: The VB is a safe method for extracting breast tissue for histological workup. The technique allows the resection of breast tissue up to?8 cm3. Besides the diagnostic indications, the method qualifies for a therapeutic resection of symptomatic benign lesions (e. g. fibroadenomas). The technique should be used in specialized breast centers working in a multidisciplinary setup. This paper is an expert's recommendation for the use of VB under sonographic guidance. It is not formulated as a nationwide guideline. 相似文献

Objectives: Patients with inherited bleeding disorders are at high risk of bleeding following oral surgery and present challenges to the oral surgeons. Aim of this study was to report our experience in dental extraction in patients exhibiting Haemophilia A and B between 2007 and 2012.
Patient and Methods: 58 dental extractions in 15 patients during 19 interventions were performed. Replacement therapy with recombinant and plasma-derived factor VIII and IX was applied systematically in combination with antifibrinolytic treatment and local haemostatic measures. The following data were recorded: type of surgery, applied local haemostatic measures, general substitution, systemic antifibrinolytic agents and occurrence of postoperative bleeding complications.
Results: Two patients presented postoperative bleeding. One had secondary bleeding requiring additional injection of factor concentrates. The other one presented epistaxis which was managed conservatively with a nasal tamponade.
Conclusions: Excellent haemostasis is achievable after dental extractions in patients with Haemophilia A and B by following a protocol using defined pre- and postoperative doses of factor concentrates in combination with haemostatic measures.
Key words:Antifibrinolytic treatment, dental extraction, Haemophilia, inherited bleeding disorders, local haemostatic measures. 相似文献
