Genotyping and antifungal susceptibility of human subgingival Candida albicans isolates.
2002
Subgingival colonization by Candida albicans has been described in human immunodeficiency virus (HIV)-infected individuals, but subgingival isolates have scarcely been characterized, particularly with respect to genotype and antifungal susceptibility. A series of 29 subgingival strains of C. albicans isolated from nine HIV-infected individuals was typed by electrophoretic karyotyping and tested for susceptibility to fluconazole, itraconazole, the new investigational triazole posaconazole and amphotericin B. DNA typing showed genetic heterogeneity within subgingival isolates, as almost every individual harbored his/her own specific isolate. Genetic identity was usually demonstrated within or…
Posaconazole or Fluconazole for Prophylaxis in Severe Graft-versus-Host Disease
2007
Invasive fungal infections are an important cause of morbidity and mortality after allogeneic hematopoietic stem-cell transplantation.In an international, randomized, double-blind trial, we compared oral posaconazole with oral fluconazole for prophylaxis against invasive fungal infections in patients with graft-versus-host disease (GVHD) who were receiving immunosuppressive therapy. The primary end point was the incidence of proven or probable invasive fungal infections from randomization to day 112 of the fixed treatment period of the study.Of a total of 600 patients, 301 were assigned to posaconazole and 299 to fluconazole. At the end of the fixed 112-day treatment period, posaconazole wa…
Association of microsatellite polymorphisms of the human 14q13.2 region with type 2 diabetes mellitus in Latvian and Finnish populations.
2007
A polymorphic microsatellite in intron 6 of the human proteasome core particle PSMA6 gene (HSMS006), and four other microsatellites localized upstream on human chromosome 14q13.2 (HSMS801, HSMS702, HSMS701, HSMS602), were genotyped in 104 type 2 diabetic patients and 129 age-matched control subjects from Latvia and replicated in 91 type 2 diabetic patients and 88 age-matched healthy control subjects from the Botnia Study in Finland. In type 2 diabetic patients from both populations the HSMS006 (TG)22 allele was two times more frequent compared to the control group. In the Latvian population the (CAA)8 allele of the HSMS602 marker was less frequent in the diabetic group, as was the (AC)24 al…
Asthmatic Bronchial Epithelium Is More Susceptible to Oxidant-Induced Apoptosis
2002
Abnormal apoptotic mechanisms are associated with disease pathogenesis. Because the asthmatic bronchial epithelium is characteristically damaged with loss of columnar epithelial cells, we postulated that this is due to unscheduled apoptosis. Using an antibody directed toward the caspase cleavage product of poly(ADP-ribose) polymerase, immunohistochemistry applied to endobronchial biopsies showed higher levels of staining in the bronchial epithelium of subjects with asthma as compared with normal control subjects (% epithelial staining [median (range) = 10.5 (1.4-24.5) versus 0.4 (0.0-9.7)]; P < 0.001). Because we were unable to determine whether this difference was due to ongoing inflammati…
Oxygen Radical Production by Alveolar Inflammatory Cells in Idiopathic Pulmonary Fibrosis
1990
Idiopathic pulmonary fibrosis (IPF) is a chronic inflammatory interstitial lung disease characterized by the accumulation of alveolar macrophages (AMs) and neutrophils in the lower respiratory tract, parenchymal cell injury, and fibrosis of the alveolar structure. Reactive oxygen intermediates (ROI) are claimed to be a major cause of tissue damage in IPF; however, the source of ROI has not been unequivocally identified. AMs, as well as neutrophils, are capable of releasing these agents. The contributions of these possible sources are not known. To address this question, we evaluated the spontaneous and stimulated (PMA or zymosan) ROI release of total bronchoalveolar cells and isolated AMs i…
Risk factors for cystic fibrosis arthropathy: Data from the German cystic fibrosis registry
2021
Epidemiology and potential risk factors for cystic fibrosis arthropathy (CFA) were studied in a relevant cystic fibrosis (CF) patient cohort.Cohort study of patients included in the German CF registry in 2016-2017. Descriptive analysis, exploratory tests and multivariable logistic regression were used to assess prevalence of CFA and associated potential risk factors for adult patients with/without chronic Pseudomonas aeruginosa infection.6069 CF patients aged from 0 to 78 years were analysed. CFA was observed in 4.9% of the patients. Prevalence was significantly higher in adult patients (8.4%) compared to patients18 years (0.7%; p0.0001). Logistic regression analyses in adult patients (n=33…
Retrospective dosimetry for Latvian workers at Chernobyl.
2001
Between 1986 and 1991 approximately 6500 Latvian inhabitants were recruited for clean-up work at the Chernobyl nuclear power plant. Their absorbed doses are usually unknown, because less than half of them had their external exposure officially documented. Clinical investigations show a high morbidity rate for these clean-up workers when compared with that of the general population. In order to understand the causes of their diseases and the impact of ionising radiation, electron spin resonance (ESR) has been used to measure the absorbed doses in human tooth enamel. The doses estimated by ESR were between two and three times higher than previously documented and are in accord with the result…
Adult exposures from MDCT including multiphase studies: first Italian nationwide survey.
2014
To evaluate the radiation dose in routine multidetector computed tomography (MDCT) examinations in Italian population.This was a retrospective multicentre study included 5,668 patients from 65 radiology departments who had undergone common CT protocols: head, chest, abdomen, chest–abdomen–pelvis (CAP), spine and cardiac. Data included patient characteristics, CT parameters, volumetric CT dose index (CTDIvol) and dose length product (DLP) for each CT acquisition phase. Descriptive statistics were calculated, and a multi-regression analysis was used to outline the main factors affecting exposure.The 75th percentiles of CTDIvol (mGy) and DLP (mGy cm) for whole head were 69 mGy and 1,312 mGy cm…
Haematopoietic stem cell transplantation for vasculitis including Behçet's disease and polychondritis: a retrospective analysis of patients recorded …
2006
Objective: To evaluate the feasibility of haematopoietic stem cell transplantation (HSCT) in vasculitis. Methods: This is a retrospective analysis of patients who had received HSCT for vasculitic diseases and have been reported to the European League Against Rheumatism autoimmune disease or European Bone Marrow Transplantation ProMISe databases. Information about the disease and outcome was obtained by a questionnaire sent to the referring centres. Response of the disease to HSCT was defined as partial or complete responses according to the ability to reduce immunosuppression after HSCT. In addition, the Medline database was searched for reports on HSCT in patients with vasculitis. Results:…
[Myringoplasties. A retrospective analysis of our surgical outcomes].
2010
Objective: The aim of this study was to present myringoplasty case results in our department. Different factors were studied to confirm their prognostic value. Materials and methods: A total of 126 myringoplasties from 2006 until 2010 were reviewed, collecting patient-related details, descriptions of the anatomical defect and the most interesting surgical aspects. Results: Subtotal perforations (35.7%) were the most frequently observed. In 89.7% of the operations, the transcanal approach was preferred. The medial technique (underlay) to the tympanic membrane was the most performed (97.6%). Cartilage was the principal graft used (82.5%). Complete closure of the perforation was obtained in 71…
