The early response of the postmenopausal endometrium to tamoxifen: expression of estrogen receptors, progesterone receptors, and Ki-67 antigen

2003

OBJECTIVE To enlighten the early response of endometrium to tamoxifen by assessing the expression of estrogen receptors, progesterone receptors, Ki-67, and the histological response in endometria from normal postmenopausal women treated for 21 days with tamoxifen. DESIGN A total of 40 women, scheduled to undergo vaginal hysterectomy because of uterine prolapse, were randomly assigned to the tamoxifen group (20 mg/day; 20 women) or the control group (20 women). Samples were obtained from the upper and the lower thirds of the uterine cavity. Standard immunohistochemical staining of estrogen and progesterone receptors and of Ki-67 was performed on frozen sections. Staining was assessed using s…

Direct oral anticoagulants for the treatment of pulmonary embolism in patients with renal impairment.

2021

Pulmonary embolism (PE) is associated with adverse outcomes and substantial morbidity and mortality. Patients with PE often have renal impairment because of shared risk factors and close links between the renal and cardiovascular systems. Furthermore, patients with PE and renal impairment are at increased risk of recurrent thrombosis. Therefore, anticoagulation is crucial to treat the acute event, prevent recurrent venous thromboembolism (VTE), and optimize patient outcomes. However, when treated with an anticoagulant, patients with renal impairment also have an elevated risk of bleeding. Direct oral anticoagulants (DOACs) are the first-choice treatment for acute VTE in eligible patients. H…

Oxidative Stress and Ubiquitin Ligases: their involvement in skeletal muscle atrophy

2015

Introduction Muscle atrophy plays a relevant role in the many very prevalent diseases. Generation of reactive oxygen species (mainly by the xanthine oxidase) and inflammation are two of the main triggers of muscle atrophy. Aim The major aim of our study was to determine the mechanism by which reactive oxygen species activate E3 ubiquitin ligases (MuRF-1 and MAFbx) cause muscle atrophy. Possible prevention by allopurinol, a well-known xanthine oxidase inhibitor widely used in clinical practice; and by indomethacin, a non-steroidal antiinflamatory drug was also studied. Materials and methods Male C57BL/6J mice (3 months old) conditioned by 14 days of hindlimb unloading with or without each tr…

Assessment of Quality of Life in Postmenopausal Women with Early Breast Cancer Participating in the PACT Trial: The Impact of Additional Patient Info…

2019

<b><i>Background:</i></b> Breast cancer patients’ self-understanding of their disease can impact their quality of life (QoL); the relationship between compliance and QoL is poorly understood. <b><i>Patients and Methods:</i></b> The Patient’s Anastrozole Compliance to Therapy (PACT) program, a prospective, randomized study, investigated the effect of additional patient information material (IM) packages on compliance with adjuvant aromatase inhibitor (AI) therapy in postmenopausal women with hormone receptor-positive early breast cancer. The QoL subanalysis presented here examined the impact of IM packages on QoL and the association between QoL…

Current methods of sedation in dental patients : a systematic review of the literature

2015

Objetive The main objective of this systematic literature review is to identify the safest and most effective sedative drugs so as to ensure successful sedation with as few complications as possible. Study Design A systematic literature review of the PubMed MEDLINE database was carried out using the key words “conscious sedation,” “drugs,” and “dentistry.” A total of 1,827 scientific articles were found, and these were narrowed down to 473 articles after applying inclusion and exclusion criteria. These 473 studies were then individually assessed for their suitability for inclusion in this literature review. Results A total of 21 studies were selected due to their rigorous study design and c…

A conservative treatment for chronic obstructive sialoadenitis by intraductal instillation of mucolytic, steroids and antibiotic solution

2021

Abstract Purposes Reporting our experience in treating chronic obstructive sialadenitis with a protocol consisting of sialoendoscopy and intraductal instillation of antibiotics, steroids and n-acetyl-cysteine (NAC) solution. Methods Prospective study of patients with chronic obstructive sialadenitis with no apparent lithiasic obstructions, with recurrent non-lithiasic sialoadenitis and patients with lithiasic sialoadenitis not solved with sialoendoscopy. In all cases, a sialoendoscopy was performed. All the patients affected by lithiasic sialoadenitis where the chronic inflammation was resolved with sialoendoscopy were excluded from the study. The mid-term follow-up was performed at 12 mont…

Cis-diaminedichloro platinum ototoxicity. An experimental study.

1985

Four groups of guinea pigs received different doses of cis-platinum. SEM and TEM showed a direct relation between the dose and the damage. The first row of OHC is the first one to be damaged. The IHC are more resistant than the OHC. The pattern of destruction is similar to the one produced by the aminoglucoside antibiotics.

Treatment of cervicofacial actinomycosis: a report of 19 cases and review of literature

2013

Objectives: Actinomycosis is a chronic suppurative granulomatous infection caused by the Actinomyces genus. Orocervicofacial actinomycosis is the most common form of the disease, seen in up to 55% of cases. All forms of actinomycosis are treated with high doses of intravenous penicillin G over two to six weeks, followed by oral penicillin V. Large studies on cervicofacial actinomycosis are lacking. Therefore proper guidelines for treatment and treatment duration are difficult to establish. The aim of this study is to establish effective treatment and treatment duration for orocervicofacial actinomycosis. Study design: A Pubmed and Embase search was performed with the focus on treatment and …

Influence of blood sampling from venipunctures and catheter systems on serial determinations of prothrombin activation fragment 1 + 2 and thrombin-an…

1993

To evaluate the influence of different blood sampling techniques on test results of thrombin-antithrombin III complex (TAT) and prothrombin fragment 1 + 2 (F1 + 2) serial determinations were performed. In six groups of nonrandomized patients (ten patients each) the concentrations of the coagulation markers of blood samples from central catheters (internal jugular, caval, Shaldon, pulmonary artery) and peripheral cannulas (17G and 18G) were compared with those of blood samples obtained simultaneously from direct venipunctures of the contralateral arm. Medians and 25th-75th percentiles of TAT and F1 + 2 concentrations of plasmas obtained from central catheters were not different from those ta…
