To assess left atrial appendage (LAA) function in hypertensive patients without treatment, transesophageal echocardiography (TEE) was performed in 46 hypertensive patients in sinus rhythm, aged 40 to 55 years, and in 16 control subjects (group I) without cardiovascular disease, aged 41 to 54 years. The hypertensive patients were divided into 2 groups according to left ventricular (LV) systolic function: group II, the group with normal LV systolic function (ejection fraction 0.63 +/- 0.08), and group III, the group with LV systolic dysfunction (ejection fraction 0.39 +/- 0.05). The LAA late emptying velocities (EVs) were significantly reduced in the hypertensive subgroups compared with the control group (P <.001), but no significant difference in the LAAEV was found between groups II and III. The LAAEV in the hypertensive patients had a significant negative correlation with diastolic blood pressure, systolic blood pressure, and left atrial (LA) diameter. The maximal LAA areas were significantly larger in the hypertensive subgroups than in the control group (P <.05). No significant difference in LAA maximal area existed between groups II and III. The maximal LAA area in the hypertensive patients had a significant positive correlation with diastolic blood pressure, systolic blood pressure, and LA diameter, but a significant negative correlation with LV ejection fraction. With TEE, LA spontaneous echocardiographic contrast (SEC) was present in 6 (43%) of 14 patients in group III (P <.01) and in 7 (22%) of 32 patients in group II (P <.05). No significant difference in the occurrence of LASEC was found between groups II and III. Left atrial appendage thrombi by TEE were observed in 4 (29%) of 14 patients in group III (P <.05) and in 4 (13%) of 32 patients in group II (P = not significant). No significant difference in the occurrence of LAA thrombus existed between groups II and III. In conclusion, in patients with untreated hypertension, marked elevation of afterload imposed on the left atrium may involve both the left atrium and the LAA, resulting in impairment of LAA function. This condition may worsen with subsequent occurrence of SEC and later, thrombus formation. Therefore assessment of LAA function may be important even in the hypertensive patient in sinus rhythm. 相似文献

To compare dose-intensified epirubicin monotherapy with a standard sequential regimen, patients with primary breast cancer and ?10 involved axillary nodes were randomised to either four 21-day cycles of epirubicin 120 mg/m2 (E120; n = 202) or four 21-day cycles of epirubicin 90 mg/m2 plus cyclophosphamide 600 mg/m2 (EC) followed by three 28-day cycles of cyclophosphamide, methotrexate and 5-fluorouracil (CMF; n = 209). Simultaneous hormonal treatment was applied in both arms. At 5 years’ median follow-up, the 5-year event-free survival (EFS) rates were 47.7% (95% confidence interval [CI], 40.2–55.2%) for E120 and 45.9% (38.5–53.3%) for EC-CMF. E120 was as effective as EC-CMF with regard to EFS (hazard ratio [HR] for E120 versus EC-CMF 1.04; 95% CI, 0.79–1.36; p = 0.79) and overall survival (HR 1.06; 95% CI 0.77–1.46; p = 0.72). The data demonstrate that 4 cycles of dose-intensified epirubicin monotherapy can be as effective as 7 cycles of standard sequential polychemotherapy in high-risk breast cancer patients with ?10 positive lymph nodes, despite treatment with a single agent and a shorter treatment duration. 相似文献

Objective: It has been widely known that cardiovascular disease (CVD) risk is increased in menopause. The aim of the study was to evaluate whether this risk was elevated in young women with diminished ovarian reserve (DOR).Methods: A hundred women with DOR and 100 women with normal ovarian reserve (NOR) attending the infertility unit at Suleymaniye Maternity, Research &;Training Hospital, were enrolled in the study. CVD risk markers such as insulin resistance (defined by the homeostasis model assessment ratio [HOMA-IR]), C-reactive protein (CRP), low-density lipoprotein (LDL), high-density lipoprotein (HDL), total cholesterol (TC), and triglyceride (TG) were assessed.Results: HOMA-IR, CRP, TG, LDL levels were higher and HDL was lower among patients with DOR compared to the controls (p?0.05 for all). There were positive associations between DOR and HOMA-IR, CRP, TG, LDL levels and a negative correlation with HDL (p?0.05 for all). However, multivariate logistic regression analysis showed that HOMA-IR, CRP, TG, and HDL were independent variables that were associated with DOR.Conclusions: CVD risk markers were increased in women with DOR. Further studies with larger groups are needed to investigate the nature of the link in these patients. 相似文献

Abstract: Here we report a patient with stage-4 bilateral cystic adrenal neuroblastomas with disseminated liver metastases and consumption coagulopathy who underwent liver transplant. Our patient was initially diagnosed with infantile hepatic hemangioendothelioma and bleeding into the adrenal glands secondary to consumption coagulopathy (Kasabach-Merritt syndrome). Liver transplant was performed as a life-saving procedure under this diagnosis. We discuss this unique patient because of the diagnostic pitfalls of this rare disease and the successful clinical outcome after LT and subsequent chemotherapy for neuroblastoma. 相似文献

Radiological findings of Dyke–Davidoff–Masson syndrome (DDMS) in patients with different etiologies are presented in our study. The study included 12 patients (seven females, five males) for whom radiological examinations were requested due to reasons such as epilepsy, mental retardation, and/or hemiplegia. CT was performed in 12, MRI in 6, MRA in 1, and DSA in 1 patient. Following imaging findings were evaluated: cerebral and cerebellar involvement (laterality, encephalomalacia), affected territories, ventricular enlargement, sulcal enlargement, calvarial thickening, and paranasal sinus enlargement hyperaeration. Age range of the patients was 5–62 (mean 34.1 ± 21.7). Left hemicrania was affected in eight patients, right hemicrania in four. Ipsilateral calvarial thickening and lateral ventricular dilatation were observed in all patients. 11 patients had ipsilateral frontal sinus hyperaeration, sulcal enlargement and encephalomalacia. Wallerian degeneration of the mesencephalon and middle fossa hypoplasia was seen in ten patients, mastoid hyperaeration, third ventricular enlargement and thalamic involvement in nine, and corpus callosum, basal ganglion injury, and sphenoid sinus hyperaeration in eight. MCA, ACA, and PCA territories were involved in six patients. Only MCA territory involvement was seen in four patients. Cerebellar atrophy was contralateral in two patients. Symmetric bilateral atrophy was observed in one patient. DDMS can be encountered with different radiological findings based on cerebral damage formation process and the extent of damage. Patients may have different levels of cerebral hemiatrophy, ipsilateral carvarial thickening, and lateral ventricular dilatation. 相似文献

Background and objective
Some authors have claimed a significant impact of β-blocking agents on outcome in epithelial ovarian cancer (EOC). This study investigated the impact of concurrent medication with selective beta blockers (SBB) in patients undergoing primary treatment for EOC.Methods
The study included all consecutive patients with primary EOC treated in two tertiary gynecological-oncologic units between 1999 and 2014. Medication was retrospectively analyzed by chart review.Results
The study cohort comprised 801 patients, of whom 141 (17.6%) had received SBB. Median age of patients without SBB medication was 56 years (range: 19–90 years) and 64 years (range: 41–84 years) in patients taking SBB (p < 0.001). The main prognostic factor FIGO stage did not differ between both cohorts. 63.8% of patients taking SBB underwent complete tumor resection compared to 74.2% of patients without SBB (p = 0.012). Patients without SBB experienced less severe post-operative complications according to the Clavien-Dindo classification (18.8% vs 29.0%; p = 0.003). Between the both groups without and with SBB intake, PFS and OS did not differ significantly (PFS: 27 months and 24 months, p = 0.40; OS: 56 months and 44, p = 0.15). Multivariate analyses did not yield any association between SBB intake and prognosis but confirmed well-known prognostic factors.Conclusions
Intake of selective β-blockers did not influence the prognosis of patients with EOC. 相似文献68.

BACKGROUND: Gingival overgrowth (GO) is a common side effect of cyclosporin A (CsA) therapy, but the exact mechanism for this is unknown. Apoptosis plays an important role in the maintenance of tissue homeostasis and mediators of this process may be involved in the pathogenesis of drug-induced GO. This study compared p53 expression, bcl-2 expression, and apoptosis in gingival samples from CsA-treated renal transplant recipients to findings in controls with gingivitis. METHODS: Twenty-two kidney recipients with CsA-induced GO and 15 systemically healthy subjects with gingivitis were included in the study. The 15 systemically and periodontally healthy volunteer control group were immunohistochemically analyzed for grades of p53 and bcl-2 expression, and were processed using terminal TdT-mediated dUTP-biotin nick-end labeling (TUNEL) technique to identify and grade levels of apoptosis. RESULTS: There were no differences between the CsA group and the control group with respect to grades of p53 and bcl-2 expression (P >0.05 for both). However, the CsA group showed a lower apoptosis grade than the control group (P <0.05). None of the clinical parameters was significantly correlated with any of the immunohistochemical findings for p53 or bcl-2 (P >0.05 for all). Similarly, grade of apoptosis was not correlated with any of the clinical parameters (P >0.05). There was a significant positive correlation between serum CsA level and level of bcl-2 expression, but serum CsA was not significantly correlated with level of apoptosis or level of p53 expression. CONCLUSION: The results indicate that the pathogenesis of CsA-induced GO might involve inhibition of apoptosis, and overexpression of bcl-2 in the setting of high serum CsA. 相似文献

Introduction
The purpose of this study is to determine the etiologies, histopathology and MDCT findings of children with fulminant hepatic failure admitted to our institution.Materials and methods
Between June 2004 and November 2006, 15 children with fulminant hepatic failure who underwent MDCT were included retrospectively in this study. Twelve patients had liver biopsies. The patients were divided into three groups as hyperacute (Group I), acute (Group II) and subacute (Group III) depending on onset of hepatic encephalopathy.Results
Hepatitis A in 4 patients, non-A, non-E hepatitis in 4; mushroom poisoning in 3; fulminant Wilson's disease in 2; autoimmune hepatitis in 1; and both hepatitis B and toxic hepatitis (with leflunomide treatment) in 1 patient were detected. MDCT of all three groups revealed diffuse reduction in hepatic attenuation in 11 patients; ascites in 9; periportal edema in 6; edema of gallbladder wall in 6; splenomegaly in 6; heterogeneous hepatic parenchyma in 6; hepatomegaly in 3; irregular contours of liver in 2; multiple micronodules in 1 and necrotic areas and regeneration in liver parenchyma in 2 patients. Histopathologic evaluation of liver biopsies showed massive hepatic necrosis, inflammatory cell infiltration and ductular proliferation in 8 patients, periportal edema in 6, edema of gallbladder wall in 5, regenerating nodules and fibrous septa consistent with cirrhotic pattern in 2, and regenerating nodules and necrotic areas in 2 patients.Conclusion
The most common MDCT findings in fulminant hepatic failure were diffuse reduction in hepatic attenuation and ascites. Massive hepatic necrosis was the most common histopathologic finding. 相似文献70.
Background/AimsFascioliasis is a zoonotic disease and one of the most neglected infectious diseases in humans. Its prevalence has been increasing significantly during the last decades. This study aimed to investigate the prevalence of fascioliasis using direct microscopy and indirect hemagglutination (IHA) technique in a region in Eastern Anatolia of Turkey.Material and MethodsThis study was conducted on the serum samples obtained from 817 patients (372 male and 445 female) between 2011 and 2018, who were suspected to have fascioliasis. IHA was used to investigate anti-Fasciola hepatica antibodies in the serum samples. Stool specimens were obtained from the seropositive patients and were examined with the native-Lugol method to identify the parasites.ResultsIt was determined that 5.5% (45/817) of all the patients were F. hepatica seropositive and 6.4% (52/817) were borderline positive. Positivity was 5.7% (21/372) among males and 5.4% (24/445) among females, and the difference in the infection rates between these groups was not significant (p=0.913). The highest number of patients who applied to the clinic was in the “45 and over” age group (317 patients); 270 patients were in the 25–44 age group. A maximum positivity of 10.3% was observed in the 7–14 age group.ConclusionPreviously, fascioliasis was considered a rare infection in humans; however, it has emerged as an important public health problem in the world. Considering fascioliasis in patients with clinical symptoms, not only with direct observation but also using serological methods, would be effective in early diagnosis and treatment of the disease. 相似文献
