Cardiopulmonary bypass (CPB) contributes to the secretion of anti-inflammatory cytokines that mediate the inflammatory response observed during open heart surgery. In addition to many factors, type of anesthesia management affects immune response and central nervous system in cardiac surgery. The aim of this study was to assess the effect of propofol versus desflurane anesthesia on systemic immune modulation and central nervous system on patients undergoing coronary artery bypass grafting. Forty patients undergoing elective coronary artery bypass graft surgery with CPB were included in this prospective randomized study. Patients were allocated to receive propofol (n?=?20) or desflurane (n?=?20) for maintenance of anesthesia. The blood samples for IL-6, IL-8, TNF-α, and S100β were drawn just prior to the operation before the induction of anesthesia, second before cardiopulmonary bypass, third after CPB, fourth 4 h postoperatively at the ICU. Major finding in our study is that S100β levels were lower in propofol group when compared to desflurane anesthesia. And also immune reaction was less in patients exposed to desflurane anesthesia when compared to propofol anesthesia as indicated by lower plasma concentrations of IL-8 and IL-6. Propofol is more preferable in terms of S100β for anesthetic management for CABG.  相似文献

Fc receptors (FcR) play an important role in immune regulation. This might be linked to the variability in immune response, therefore relating to the pathogenesis of atopic diseases. The aim of the present study was to evaluate the Fc γ RIIIa gene polymorphism in Turkish children with asthma and allergic rhinitis. The study included 364 atopic children (184 bronchial asthma, 180 allergic rhinitis) and 234 healthy subjects as the control group, aged between 5 to 16 years. Patients were recruited from outpatient clinics of allergy and general pediatric care. Plasma IgE concentrations were measured by immunoassays and skin prick test was done in children with atopic diseases. The Fc γ RIIIa gene polymorphism was determined using the polymerase chain reaction method. Distribution of V158V genotype was significantly different among patient groups compared to controls (for asthmatic children OR: 5.33, 95% CI: 2.80–10.23, p < 0.001; for allergic rhinitis OR: 3.25, 95% CI: 1.75–6.07, p = 0.001). Distribution of 158 V allele was significantly different among asthmatic children (OR: 2.20, 95% CI: 1.65–2.92, p < 0.001) and allergic rhinitis patients (OR: 1.77, 95% CI: 1.32–2.35, p < 0.001) compared to healthy controls. Our study shows that the V158V genotype in Fc γ RIIIa gene polymorphism may be a genetic risk factor for the development of atopic diseases.  相似文献

Recently, it is claimed that the usage of the intranasal glucocorticosteroids alone, instead of H1-antihistamines + intranasal glucocorticosteroids, reduces the complaints in moderate-to-severe seasonal allergic rhinitis (SAR). This study aims to evaluate the efficacy of the intranasal glucocorticosteroids alone during the pollen season by using objective and subjective parameters. Twenty-four patients (mean age, 12.17 +/- 2.26 years) with SAR sensitive to pollen are included in this study. The patients were divided into two groups randomly. Twelve patients in group I were given H1-antihistamine (loratadine) + intranasal glucocorticosteroid (mometasone furoate), and 12 patients in group II were given only intranasal glucocorticosteroid (mometasone furoate) for 12 weeks. To evaluate the results, subjective parameters (daytime nasal symptoms score, daytime eye symptoms score, and nighttime symptoms score) and objective parameters (nasal smear, nasal peak inspiratory flow [NPIF], and nasal biopsy) are used. With regard to the baseline data, it was observed that both groups had a significant decrease in total symptom score (p < 0.01), a significant increase in NPIF values (p < 0.01), and a significant decrease in the number of eosinophils in both nasal smear and biopsy (p < 0.01) after treatment. Comparing groups I and II in terms of treatment success, the improvement in daytime nasal symptoms score (p < 0.01 versus p < 0.01), daytime eye symptoms score (p < 0.01 versus p < 0.01), and total symptom score (p < 0.versus p < 0.01) was not different. However, there was a significant improvement in nighttime symptoms score between groups I and II (p < 0.01 versus p > 0.05). Furthermore, NPIF and nasal biopsy findings did not differ between groups (p > 0.05). The usage of H1-antihistamine + intranasal glucocorticosteroid has no superiority over the administration of intranasal glucocorticosteroid alone for treatment of SAR in pollen season. However, this finding needs to be confirmed in larger series studies.  相似文献

Eponym     
Scimitar syndrome is a rare congenital anomaly, characterized by partial or complete anomalous pulmonary venous drainage of the right or left lung into the inferior vena cava. The syndrome is commonly associated with hypoplasia of the right lung, pulmonary sequestration, persisting left superior vena cava, and dextroposition of the heart. The pathogenesis of the syndrome is unclear, but it seems to originate from a basic developmental disorder of the entire lung bud early in embryogenesis. Two main forms of scimitar syndrome have been described. Signs and symptoms can start during infancy (infantile form) or beyond (childhood/adult form). The infantile form generally presents within the first 2 months of life with tachypnea, recurrent pneumonia, failure to thrive, and signs of heart failure. The diagnosis of scimitar syndrome is usually made based on the characteristic chest X-ray films and can be confirmed by angiography; however, it is now done mostly by transthoracic or transesophageal echocardiography, noninvasive computed tomography, or magnetic resonance angiography. Fetal echocardiography using three-dimensional power Doppler imaging permits prenatal diagnosis. Most frequently, patients are asymptomatic in the absence of associated abnormalities and can be followed conservatively. For patients with congestive heart failure, repeated pneumonia, or pulmonary-to-systemic blood flow ratios greater than 1.5 and pulmonary hypertension, it is important to reroute the anomalous right pulmonary veins and repair the associated cardiac defects in order to avoid progression to right ventricular failure. The triad of respiratory distress, right lung hypoplasia, and dextroposition of the heart should alert the clinician to think of scimitar syndrome.  相似文献

Invasive pulmonary aspergillosis is a serious infectious complication in immunocompromised especially neutropenic patients. Despite improvements in early diagnosis and effective treatment, invasive pulmonary aspergillosis is still a devastating opportunistic infection. These infections also interfere with the anticancer treatment. We report our experience in the diagnosis and therapeutic management of sinopulmonary aspergillosis in 4 children with hematologic malignancy. All patients except the first were neutropenic when sinopulmonary aspergillosis was diagnosed. Clinical signs included fever, cough, respiratory distress, swallowing difficulty, headache, facial pain-edema and hard palate necrosis. Radiodiagnostic methods showed bilateral multiple nodular infiltrations, soft tissue densities filling all the paranasal sinuses, and bronchiectasis. Diagnosis of aspergillosis was established by bronchoalveolar lavage in one case, tissue biopsy, positive sputum and positive cytology, respectively, in the other 3 cases. One patient was treated with liposomal amphotericin B and other 3 cases were treated with liposomal amphotericin B + itraconozole. Outcome was favorable in all cases except the one who died due to respiratory failure. Early diagnosis, appropriate treatment and primary disease status are important factors on prognosis of Aspergillus infections in children with hematological malignancy.  相似文献
