We aimed to determine long-term prognostic role of echocardiographic and hematologic parameters in heart failure patients complicated with incidental pleural effusion (PE) diagnosed during echocardiographic evaluation. The study was performed by evaluating patient records in which PE was incidentally detected during echocardiographic examination in a tertiary teaching hospital between Jan 2002 and Dec 2012. Total 151 patients with heart failure complicated with PE were analyzed. All patients’ mortality data were collected from registry center of Social Insurance Institution which is officially responsible for recording all mortality data in Turkey. Detailed echocardiographic and hematologic parameters including creatinine, uric acid, albumin, sodium, potassium, hemoglobin at the time of hospital admission were analyzed. Data from 151 eligible patients were analyzed. We compared patients who died (n = 51) during follow-up with the survivors (n = 100) in terms of patients’ echocardiographic and hematological features. Mean duration of follow-up was 71.5 ± 45.6 months. Fifty-one patients (33.8 %) died during this follow-up period. From all echocardiographic parameters only dilated left atrium (LA) diameter was found to be associated with a poor prognosis (p = 0.034). Low albumin, sodium and hemoglobin levels were associated with poor prognosis (p < 0.001, p = 0.002 and p = 0.007, respectively). We showed that dilated LA, as well as low albumin, low sodium and low hemoglobin levels had a worse prognostic significance than patients with normal LA size, within normal limits of albumin, sodium and hemoglobin levels in patients with heart failure complicated with PE determined incidentally by echocardiography. 相似文献

Core needle biopsy is widely used to diagnose spinal lesions. Final histopathological report of the specimen usually can be given after several days. These several days delay may prevent early treatment in some patients. Our aim was to investigate if treatment of spinal lesions could be started according to the immediate cytologic evaluation of the core needle biopsy. The cytological materials of the 213 core needle spinal biopsy were prepared immediately after biopsy procedure. Of these biopsies, only 101 core needle biopsy had a final diagnosis which formed the backbone of the current study. Cytological materials of these cases were compared with both histopathologic results of the core biopsy and with final diagnosis obtained by open surgery or clinical follow up. According to final diagnoses 40 patients had infections, 59 patients had neoplasms and 2 patients had no pathology. When the diagnosis that determines the treatment is considered, the overall success rates (positive predictive value:PPV) of cytology and histology were 0.65 and 0.76 respectively. Moreover when the specific diagnosis were analyzed separetely in the subgroups of tuberculous infection, lymphoma and plasmacytoma; PPV of both cytological and histological assessments was 1.00. In spinal metastasis, PPV was 0.97 for cytology and 1.00 for histology. Rapid cytologic interpretation of core needle biopsy material is a useful and reliable tool to determine the spinal lesions which require urgent treatment. When the cytological specimen reveals the diagnosis of spinal metastasis, lymphoma, plasmacytoma or tuberculosis, the treatment may be started without waiting the result of the histological examination. 相似文献

In order to establish good health politics for stroke survivors, regional differences in factors affecting the outcome of patients have to be known. For this purpose we investigated factors affecting 1 year mortality and functional outcome in patients with first-ever-in a lifetime stroke in the region of Antalya, Turkey. One-hundred and forty-seven patients with a first ever stroke were included and followed up for at least one year. The modified Rankin Scale was used for evaluation of handicap. Several factors known to affect prognosis such as demographic features, socioeconomic status, stroke subtype, neurological findings and stroke risk factors were compared between patients who died during follow-up and survivors. Of the 147 patients 35 (23.8%) died during the course of the study. Multivariate logistic regression analysis showed that only illiteracy, being single or widowed and presence of urinary incontinence were significant predictors of being dead at the end of 1 year. In the survivors factors independently affecting dependence at the end of one year were age, presence of coma on admission and urinary incontinence. Our results suggest that not only stroke severity but also socioeconomic variables are important in determining the prognosis of stroke patients. 相似文献

The aim of this study was to assess the middle latency auditory evoked potential (MLAEP) findings in idiopathic Parkinson's disease (IPD) and in patients who are regarded as having atypical parkinsonian disorders (AP) and to determine whether MLAEPs could contribute to the differential diagnosis of IPD and AP.MLAEPs were evaluated in 19 control subjects and in a total of 35 patients with parkinsonism, of which 27 had IPD and 8 had AP. Among IPD patients, P1 was absent in 1 nondemented patient with young-onset Parkinson's disease (YOPD) (5%) and in 2 of 7 demented (28.5%) IPD patients. In the AP group, 3 of the 7 (42.8%) nondemented patients and the one patient with dementia showed the absence of P1. The absence of P1 was found to be significantly higher in AP patients than IPD patients (p=0.0335).In conclusion, MLAEPs were found to be normal in nondemented IPD patients with only a few exceptions. The absence of P1 in nondemented patients with parkinsonian symptoms may bring the diagnosis of IPD into question. The absence of P1 could be detected in AP patients at least as often as in demented IPD patients. Thus, the measurement of MLAEPs may be a clinically useful adjunct to the clinical examination of patients with parkinsonism. 相似文献

The objective of this study was to investigate the effects of Daflon 500 mg on tissue damage in kidney after ischemia/reperfusion hindlimb, by assessing blood biochemical assay and histopathological analysis. Rats were given Daflon 80 mg x kg(-1) x day(-1) for 10 days. On 11th day of treatment, 4h ischemia followed by 4 h reperfusion period was performed on right hind limb of the rats. Control groups were given only arabic gum and were subjected to same ischemia/reperfusion period.At the end of reperfusion period, erythrocyte superoxide dismutase, Na(+)-K(+) ATPase and reduced glutathione levels were increased in the rats erythrocytes in Daflon group (P<0.01, for all). On the other hand, serum myeloperoxidase and malondialdehyde levels were significantly lower in the Daflon-received rats (P<0.01, for all). Histopathological studies demonstrated that, there was a prominent tubulointerstitial injury with loss of brush border and this degeneration was accompanied by segmental glomerular degeneration also for both control and Daflon group. Daflon-received group animals displayed significantly less periglomerular and perivascular leukocytic infiltration (P=0.015).These overall results suggest that Daflon contributes renal protection from hind limb ischemia/reperfusion injury in some degree, by decreasing systemic oxidative stress. 相似文献

We studied by a whole genomic approach and trios genotyping, 12 de novo, nonrecurrent small supernumerary marker chromosomes (sSMC), detected as mosaics during pre‐ or postnatal diagnosis and associated with increased maternal age. Four sSMCs contained pericentromeric portions only, whereas eight had additional non‐contiguous portions of the same chromosome, assembled together in a disordered fashion by repair‐based mechanisms in a chromothriptic event. Maternal hetero/isodisomy was detected with a paternal origin of the sSMC in some cases, whereas in others two maternal alleles in the sSMC region and biparental haplotypes of the homologs were detected. In other cases, the homologs were biparental while the sSMC had the same haplotype of the maternally inherited chromosome. These findings strongly suggest that most sSMCs are the result of a multiple‐step mechanism, initiated by maternal meiotic nondisjunction followed by postzygotic anaphase lagging of the supernumerary chromosome and its subsequent chromothripsis. 相似文献

Echinococcus granulosus remains a clinical problem in undeveloped and developing countries. It commonly affects the liver and lung, but, rarely, other organs such as the heart can be involved. In this report, we describe an unusual case in which pericardial hydatid cyst mimicking acute coronary syndrome secondary to compression by pericardial hydatid cyst attached to the anterolateral wall of the left ventricle. We made diagnosis by transthoracic 2D echocardiography, and confirmed by cardiac magnetic resonance imaging and serologic tests. Because our patient refused to have an operation, albendazole therapy was given. It is important to recognize this unusual disease, because it may lead to serious complications. 相似文献
