Introduction
Epistaxis is the most frequent manifestation in hereditary hemorrhagic telangiectasia, in which no optimal treatment exists. It can lead to severe anemia and reduced quality of life. Positive effects of tranexamic acid, an antifibrinolytic drug, have been reported on epistaxis related to this disorder. We sought to evaluate the efficacy of treating nosebleeds in hereditary hemorrhagic telangiectasia with tranexamic acid.Materials and Methods
In a randomized, double-blind, placebo controlled, cross-over phase IIIB study, 1 gram of tranexamic acid or placebo was given orally 3 times daily for 3 months for a total of 6 months.Results
22 patients were included in the intention-to-treat analysis. Hemoglobin levels, the primary outcome measure, did not change significantly (p = 0.33). The secondary outcome measure was epistaxis score and patients reported a statistically significant reduction in nosebleeds, equaling a clinically relevant 54% diminution (p = 0.0031), as compared to the placebo period. No severe side effects were observed.Conclusion
Tranexamic acid reduces epistaxis in patients with hereditary hemorrhagic telangiectasia.(Clinical trial registration numbers: BfArM 141 CHC 9008–001 and ClinicalTrials.gov NCT01031992) 相似文献102.

The authors describe the use of bone cement containing calcium phosphate for vertebroplasty of the cavity in the base of odontoid process. A 23-year-old female patient was operated on by incision in lateral cervical area (anterior open access). After a blunt dissection, the working cannula (Kyphon) was introduced under fluoroscopic guidance through the C2 vertebral body to the cavity in the base of the odontoid process. Intraoperatively biopsy of the lesion was taken and histopathological examination excluded the presence of neoplasm. The cavity, presumably haemangioma, was successfully filled with calcium phosphate bone cement KyphOs? FS (Kyphon). The proper filling without paravertebral cement leak was confirmed by postoperative computed tomography (CT). The CT and magnetic resonance imaging performed 9 months after the procedure showed that cement was still present in the cavity. This is the first use of calcium phosphate cement to conduct the vertebroplasty of C2 vertebra. 相似文献

Hemiparkinsonism-hemiatrophy (HPHA) is a rare neurological syndrome. The main clinical features of HPHA consist of atrophy of one side of the body (face, trunk, limbs), ipsilateral hemiparkinsonism (bradykinesia, rigidity, tremor) and in many cases dystonia. There are no data on prevalence of HPHA as the condition is rare. The mean age of parkinsonism onset is earlier than in idiopathic Parkinson disease (43.7 years, range: 15–63). Changes in magnetic resonance imaging (MRI) (cortical, basal ganglia atrophy contralaterally to the side of clinical presentation) are described in 30% of patients. The pathogenesis of HPHA is unknown, but in many cases a history of prenatal injuries was reported.We present two male patients with HPHA – 45 and 55 years old, with left-sided parkinsonism, dystonia and hemiatrophy (to our knowledge, the first Polish cases). Both patients had no atrophic changes in MRI and levodopa treatment was ineffective. In the discussion the authors review current literature on HPHA. 相似文献

目的:对传统中药饮片调剂方式与中药配方颗粒调剂方式进行应用分析比较,优化调剂方法。方法统计并分析本院传统中药饮片与中药配方颗粒的使用数据(调剂出错率、处方数等),并随机抽取180例于该院就诊的患者及12名在该院从事配药的工作人员进行问卷调查,在患者选择和工作人员选择等方面对传统中药饮片调剂方式与中药配方颗粒调剂方式进行对比分析。结果与传统中药饮片调剂方式相比,中药配方颗粒调剂方式在出错率、取药方便程度、药品剂量准确度、卫生、食用方便程度、携带存储及提高工作效率、降低工作强度、减少药物浪费等方面具有显著优势(P<0.01)。结论中药配方颗粒调剂方式具有明显优势,但还存在许多不足,需要中医药工作者的不断完善与改进,发挥中医药优势。 相似文献

Studies of interferon- (IFN-)therapy for chronic hepatitis C have focused on viralclearance; however, few have evaluated patient'shealth-related quality of life during therapy. Thisstudy evaluates health-related quality of life and theprevalence of anxiety and depression in patients withchronic hepatitis C before, during, and followingIFN- therapy. Patients undergoing IFN-therapy for chronic hepatitis C were asked to completehealth status measures as well as anxiety and depressioninventories before, during, and following IFN-therapy. These measures were compared to the results of healthy adults in the general US population.Thirty-eight of forty-eight eligible patients (79%) withchronic hepatitis C completed the questionnaires.Respondents demonstrated a significant increase in depression during the sixth month ofinterferon therapy in comparison to pretreatmentresults. Anxiety scores improved significantly after onemonth of IFN- in comparison to pretreatmentresults. Scores on the health status measures did notvary with IFN- therapy. Patient responses wereanalyzed with respect to biochemical response(normalized transaminases) to IFN-. IFN-responders, who were aware of their transaminase results,exhibited lower scores on anxiety subscales during andafter therapy (P = 0.02-0.04). Scores on the healthstatus subscale, role emotional, improved in IFN- responders compared to nonresponders during thesixth month of therapy (P = 0.02). Response toIFN- therapy was not associated with any otherdifferences on subscale analysis. Patients with chronichepatitis C exhibited health perceptions similar to thegeneral US population, and these were unchanged duringIFN- therapy. However, the incidence ofdepression significantly increased during the sixthmonth of IFN- therapy. IFN- respondersexhibited fewer emotional problems as well as a lowerincidence of anxiety during and followingtherapy. 相似文献

Summary In chronic heart failure cardiac -adrenoceptors are decreased. In this study we investigated whether a) in severely failing human ventricles -adrenoceptors are uniformly decreased or regional variations exist, and b) the -adrenoceptor decrease is caused by increased internalization or is a real loss in -adrenoceptors. For this purpose we assessed -adrenoceptor number and subtype distribution in a particulate fraction (mainly sarcolemmal plasma membranes) and a light vesicle fraction of right and left ventricular segments (obtained by cutting transversal, rings of 2 cm from the midventricular regions) of explanted hearts from 2 patients with end-stage congestive dilated cardiomyopathy (DCM) and one patient with end-stage ischemic cardiomyopathy (ICM). In all three hearts ventricular -adrenoceptor number was very low (7.5–10 and 21–26 fmol/mg protein in DCM, 15–22 fmol/mg protein in ICM compared to 68–74 fmol/mg protein in non-failing ventricles). -Adrenoceptors were uniformly decreased over the whole ventricular region and no considerable regional variations existed. The same held true for 1- and 2-adrenoceptors. In ICM decrease in -adrenoceptors was due to a concomitant reduction in 1- and 2-adrenoceptors, in DCM it was mainly caused by 1-adrenoceptor down-regulation. In all ventricular segments investigated light vesicle -adrenoceptors amounted to about 5–7% of total ventricular -adrenoceptors and this was not significantly different from non-failing left ventricles. We conclude that a) in severely failing human ventricles -adrenoceptors are evenly down-regulated and no regional variations exist and b) the decrease in -adrenoceptors is not due to enhanced internalization but is a real loss of -adrenoceptors.Abbreviations DCM
