Results of a Phase II Study of Pixantrone in Combination with Cyclophosphamide, Vincristine, and Prednisone in Patients with Relapsed Aggressive Non-…
2006
Abstract Background: Pixantrone is a novel aza-anthracenedione with less cardiotoxicity and superior activity compared to doxorubicin and mitoxantrone in murine leukemia and lymphoma tumor models. Pixantrone as single agent therapy led to major responses in patients (pts) with multiply relapsed aggressive non-Hodgkin’s lymphoma (NHL), including diffuse large B-cell lymphoma (DLCL). In a phase I dose-ranging study of pixantrone (80 to 180 mg/m2) replacing doxorubicin (CPOP) in a CHOP-like regimen, the optimal dose (RD) from that study was found to be 150 mg/m2. Methods: In this international, multi-center, phase II study the primary objective was to assess the efficacy and safety of the CPOP…
Comparación de las frecuencias de los alelos factor V Leiden (G1691A) y protrombina-G20210A entre pacientes con trombosis venosa profunda y población…
2006
Background: Factor V leiden and the -G20210A variant of prothrombin gene are associated to a higher risk of deep venous thrombosis. Aim: To assess the frequency of factor V Leiden (G1691A) and prothrombin -G20210A alleles in patients with deep venous thrombosis (DVT) and in the general population from Spain. Material and methods: Factor V Leiden (g1691a) and prothrombin-g20210a alleles were genotyped in 493 individuals from the Spanish general populations and in 131 patients with DVT. The presence of DVT was confirmed by phlebography. Allelic frequencies and the DVT risk associated with these variants were estimated. Results: Allelic frequencies for the factor V Leiden (G1691A) allele were …
Apoptotic role of Fas/Fas ligand system in the regulation of erythropoiesis
1999
Abstract The possible involvement of Fas and Fas ligand (FasL) in the regulation of erythropoiesis was evaluated. Immunohistochemistry of normal bone marrow specimens revealed that several immature erythroblasts undergo apoptosis in vivo. Analysis of bone marrow erythroblasts and purified progenitors undergoing unilineage erythroid differentiation showed that Fas is rapidly upregulated in early erythroblasts and expressed at high levels through terminal maturation. However, Fas crosslinking was effective only in less mature erythroblasts, particularly at basophilic level, where it induced apoptosis antagonized by high levels of erythropoietin (Epo). In contrast, FasL was selectively induced…
Isolated erythema (cellulitis) of the breast.
2002
Abstract This paper reports nine cases of breast cellulitis in women patients (four cases in pregnancy, four postmenopausal cases following hormone replacement therapy and one case of unilateral breast oedema following a mediastinal lymphoma). Biopsies were obtained from the erythematous area in one pregnant patient, one postmenopausal patient and the patient with breast oedema associated with the mediastinal lymphoma. Histology revealed unspecific dermatitis with extensive perivascular lymphoplasmocellular infiltrates. Histopathological examination of biopsies obtained from the underlying mammary tissue along with the corresponding mammographic data gave no evidence of mastitis or mammary …
Confronting the psychological burden of haemophilia
2010
Providing comprehensive care, counselling and support to haemophilic patients, and their parents have always been quite complex for haemophilia treatment centres. Nowadays, starting with recent developments in genetic counselling, prenatal diagnosis and carrier testing, the psychological burden on patients and parents might possibly have increased, compared with even the recent past. The emotional strains and worries associated with a possibly affected newborn and his care through childhood and adolescence may also have a grievous impact on couple dynamics and marital relationship. The impact may be even higher in families in which haemophilia is newly diagnosed. The main psychological prob…
Synergistic effects of fluticasone propionate and salmeterol on in vitro T-cell activation and apoptosis in asthma
2004
Background In asthma T cells are characterized by an increased activation state and by reduced apoptosis. Objective Because the clinical efficacy of inhaled corticosteroids combined with long-acting β 2 -agonists has been widely demonstrated in asthma, we studied, in vitro , the effect of fluticasone propionate (FP) and salmeterol alone and in combination on the activation and apoptosis of peripheral blood T cells (PBTs), on the expression of phosphorylated nuclear factor κB inhibitor (IκBα), and on the nuclear translocation of glucocorticoid receptor (GR) in PBTs from asthmatic subjects. Methods Apoptosis was evaluated on the basis of annexin V binding, whereas the expression of caspases 8…
"Doctor, tengo un bulto en la axila". Adenomegalia siliconomatosa postmamoplastia de aumento: a propósito de ocho casos
2010
La aparición de adenopatías axilares asociadas a mamoplastia de aumento mediante prótesis de silicona es un hecho infrecuente, no excepcional, y muy preocupante para paciente y cirujano. Hemos hecho una revisión de 1697 historias clínicas de pacientes sometidas a mamoplastia de aumento mediante prótesis de silicona al objeto de estudiar la relación entre roturas protésicas y adenopatías axilares Las 1697 pacientes se dividieron en grupos que cumplían 1, 2, 3, 5 y 7 años de haber sido intervenidas. Revisamos sus historias clínicas y estudiamos las que con posterioridad a la cirugía habían consultado por sospecha de rotura protésica y adenopatías axilares. No encontramos roturas protésicas an…
Best practices and recommendations for drug regimens and plasma exchange for immune thrombotic thrombocytopenic purpura.
2021
Introduction Thrombotic thrombocytopenic purpura (TTP) is a life-threatening thrombotic microangiopathy characterized by microangiopathic hemolytic anemia, thrombocytopenia, and organ injury. TTP pathophysiology is based on a severe ADAMTS13 deficiency, and is a medical emergency with fatal outcome if appropriate treatment is not initiated promptly. Areas covered Authors will review the best options currently available to minimize mortality, prevent relapses, and obtain the best clinical response in patients with immune TTP (iTTP). Available bibliography about iTTP treatment has been searched in Library's MEDLINE/PubMed database from January 1990 until April 2021. Expert opinion The general…
Effects of the number of removed lymph nodes on survival outcome in patients with sentinel node-negative breast cancer.
2021
Abstract Background Sentinel lymph node biopsy is the gold standard surgical technique for axillary staging in patients with clinically node-negative. However, it is still uncertain what is the optimal number of sentinel lymph nodes (SLNs) to be removed to reduce the false-negative rate. The aim of this study was to investigate whether patients with a single negative SLN have a worse prognosis than those with two or more negative SLNs. Methods A retrospective review was conducted on a large series of SLN-negative breast cancer patients. Survival outcomes and regional recurrence rate were evaluated according to the number of removed SLNs. Secondly, the contribution of different adjuvant ther…
High-Dose Therapy and Autologous Hematopoietic Stem Cell Transplantation (ASCT) Has a Significant but Transient Impact on Quality of Life: Lessons Fr…
2011
Abstract Abstract 1989 Objective: High-dose therapy (HDT) and ASCT is the standard of care in a variety of hematologic malignancies. Whereas for some indications a survival advantage for HDT and ASCT has been demonstrated, a benefit only in terms of better progression-free survival has been shown for CLL. Because of this the quality of life (QoL) deserves particular attention. QoL assessment was a major focus of a randomized controlled EBMT-Intergroup trial on the value of HDT compared to observation in first or second remission of CLL (Michallet, Blood, 2011). Methods: 222 patients were enrolled into the study and allocated to either ASCT or observation. In the transplant arm, 72% received…
