The relationship between viral infections and acute pancreatitis (AP) is not well-defined and universally accepted. Although an association is debated due to lack of solid evidence, a vast number of case reports suggest a possible interrelation. Influenza A virus is one of the most common infectious pathogens in humans but the incidence of subclinical or overt AP during the course of flu is unknown. We report a case of AP, which occurs shortly after a H1N1 infection during the pandemic in 2009. 相似文献

OBJECTIVE: To compare the mechanism of action of raloxifene and gosereline induced shrinkage of leiomyomas via estrogen receptor, progesterone receptor, bcl-2 and p53 expression immunohistochemically. STUDY DESIGN: Thirty-two premenopausal women affected by uterine leiomyomas were randomized into two equal groups. Group A was treated with gosereline (3.6 mg subcutaneous injection monthly) and group B was treated with raloxifene (60 mg daily per os) for 3 months before undergoing surgery. At entry and at the end of the treatment the leiomyoma volume was measured ultrasonografically and the volume change was calculated. Immunohistochemical detection of estrogen receptor (ER), progesterone receptor (PR), bcl-2 and p53 were performed on leiomyoma tissue samples from group A, group B and the matched-control group. H-scores for ER, PR, bcl-2 and p53 were calculated. The mean volume changes of leiomyomas and immunohistochemical H-score differences of ER, PR, bcl-2 and p53 were compared between groups. RESULTS: The leiomyoma volume decreased significantly after treatment in gosereline group from baseline of 65 cm(3) to 35 cm(3), and in raloxifene group from 68 cm(3) to 50 cm(3), p<0.05. The difference between the before and after treatment leiomyoma volumes between the two treatments was not statistically significant. H-score of ER expression was significantly lower in gosereline group compared to control group (54.4 versus 113.2, p = 0.001), whereas H-score of PR expression was significantly lower with both gosereline and raloxifene groups compared to control group (64.8 for gosereline versus 94.6 for control, 73.6 for raloxifene versus 94.6 for control, p = 0.001). The bcl-2 expression was higher in both gosereline and raloxifene groups compared to control group (173.7 for gosereline versus 94.7 for control, 179.7 for raloxifene versus 94.7 for control, p = 0.001). The p53 expression was only lower with gosereline than the control group (169.4 versus 205.6, p = 0.001), whereas there was no significant change between the raloxifene group and the control group (201.9 versus 205.6) (p>0.05). CONCLUSION: Raloxifene was as effective as gosereline in reducing leiomyoma volumes. Decreased PR expression may be a mechanism for tumor growth reduction in raloxifene treatment. In both treatment modalities, the mechanism of shrinkage of leiomyomas could not be increased apoptosis mediated by bcl-2 and p53 expression and should be investigated by further studies. 相似文献

B cells have classically been recognized for their unique and indispensable role in the production of antibodies. Their potential as immunoregulatory cells with anti-inflammatory functions has received increasing attention during the last two decades. Herein, we highlight pioneering studies in the field of regulatory B cell (Breg) research. We will review the literature on Bregs with a particular focus on their role in the regulation of allergic inflammation. 相似文献

In this review, we discuss recent publications on asthma and review the studies that have reported on the different aspects of the prevalence, risk factors and prevention, mechanisms, diagnosis, and treatment of asthma. Many risk and protective factors and molecular mechanisms are involved in the development of asthma. Emerging concepts and challenges in implementing the exposome paradigm and its application in allergic diseases and asthma are reviewed, including genetic and epigenetic factors, microbial dysbiosis, and environmental exposure, particularly to indoor and outdoor substances. The most relevant experimental studies further advancing the understanding of molecular and immune mechanisms with potential new targets for the development of therapeutics are discussed. A reliable diagnosis of asthma, disease endotyping, and monitoring its severity are of great importance in the management of asthma. Correct evaluation and management of asthma comorbidity/multimorbidity, including interaction with asthma phenotypes and its value for the precision medicine approach and validation of predictive biomarkers, are further detailed. Novel approaches and strategies in asthma treatment linked to mechanisms and endotypes of asthma, particularly biologicals, are critically appraised. Finally, due to the recent pandemics and its impact on patient management, we discuss the challenges, relationships, and molecular mechanisms between asthma, allergies, SARS-CoV-2, and COVID-19. 相似文献

IntroductionWe aimed to investigate the efficacy and side effects of bendamustine in relapsed/refractory lymphoma patients in Turkey.Material and methodsIn this retrospective study, we included relapsed/refractory Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) patients who underwent multiple lines of chemotherapy. The primary endpoint was to determine the objective response and toxicity.ResultsNinety-nine patients with a median age of 59.8 years were included in the study. Eighty-one patients had NHL (follicular lymphoma: 10, diffuse large B-cell lymphoma: 27, mantle-cell lymphoma: 18, marginal zone lymphoma: 9, small lymphocytic lymphoma/chronic lymphocytic leukemia: 17) and 18 patients had HL. The patients had previously received a median of three lines of chemotherapy (range: 2–8) except autologous stem cell transplantation (ASCT); 19 patients (HL: 11, NHL: 8) had undergone ASCT. The objective response rate (ORR) was 74.3%, the complete response rate was 57% (= 53), and the partial response rate was 16.6% ( = 19). The overall survival (OS) rate at 1 year was 74.6%. The progression-free survival (PFS) rate at 1 year was 62.5%. The most common side effects were lymphopenia, anemia and neutropenia. Side effects which were observed as grade 3 and higher levels were lymphopenia (14.1%), neutropenia (10.1%) and fatigue (7.1%).ConclusionsObjective response rate of bendamustine was found to be 74.3% in relapsed/refractory HL and NHL patients. It appears to be an effective option as a salvage treatment for patients who have previously received multiple lines of therapy. 相似文献

Introduction Dilatation of the fetal intra-abdominal umbilical vein is a rare entity. It is unclear whether prenatally diagnosed umbilical vein dilatation is associated with an increased risk of fetal anomalies or poor perinatal outcome. Umbilical artery waveform notching may be a predictor of cord abnormalities. It seems reasonable following the baby closely after the diagnosis of both conditions.Case report and discussion We present here a new case diagnosed by ultrasonography at 30 weeks of gestation with normal fetal outcome and discuss the clinical features and the management of these rare abnormalities. 相似文献

BACKGROUND: The effects of sociocultural status on periodontal conditions in pregnant women have been reported by a number of researchers and there have been speculations about the effects of hormonal changes, patients' systemic health, and socio-cultural characteristics on periodontal health during pregnancy. METHODS: This study evaluates the periodontal condition of 61 pregnant women at their first, second, and third trimesters, and the relation between the demographic (age, professional level, education) and clinical variables (previous periodontal care, frequency of tooth brushing). The clinical indices, including plaque index, gingival index, and probing depth measurements were repeated at the first, second, and third trimesters. The statistical tests used were stepwise analysis and paired sample test. RESULTS: The results of the study showed that the plaque index, gingival index, and probing depth scores increased gradually in the first, second, and third trimesters, although oral hygiene instructions were given to the entire study population. The level of statistical significance was established at P <0.05. When the clinical parameters and demographic variables were compared, only educational level and periodontal care seemed to be statistically significant (P<0.05). CONCLUSIONS: Our clinical index scores were related to the educational level of the study population. When the educational level of the study group decreased, the plaque, gingival index, and probing depth scores contrarily increased. Also non-attendance for previous periodontal care increased the scores of plaque index and probing depth. In view of the results of our study, it might be suggested that simple preventive oral hygiene programs may help maintain healthy gingiva during pregnancy. 相似文献
