Serum androsterone conjugates differentiate between acne and hirsutism in hyperandrogenic women
1991
Objective To determine if among hyperandrogenic women acne may be differentiated from hirsutism by markers of peripheral androgen metabolism. Design Prospective outpatient study of 36 hyperandrogenic women and controls divided into groups based on the presence or absence of significant hirsutism and the presence or absence of moderate to severe acne. Serum levels of adrenal and ovarian derived androgens were elevated but similar in all patient groups. Interventions Measurement of serum androgens including metabolites of 5 α -reductase activity: 3 α -androstanediol glucuronide and sulfate and androsterone (A) glucuronide and sulfate. Results 3 α -androstanediol glucuronide and sulfate were e…
Aspects of excessive antibiotic consumption and environmental influences correlated with the occurrence of resistance to antimicrobial agents
2021
International audience; This article explores the correlation between specific aspects of antibiotic usage, their resistance development, and environmental factors. The indiscriminate use of antibiotics led to environment contamination, selection and spreading of antibiotic-resistant organisms, and alteration of the microbial ecosystems balance. Sociobehavioural environmental factors and changes in the natural environment are major contributors to resistance development. Resistant bacteria strains' isolation in food, water, soil etc. demonstrates the environmental influence on the strains through antibiotics accumulation in the environment. It is difficult to assess the impact of antibiotic…
Combined use of antifibrinolytics and activated prothrombin complex concentrate (aPCC) is not related to thromboembolic events in patients with acqui…
2019
Antifibrinolytics combined with aPCC are not routinely administered to patients with acquired hemophilia A due to increased thrombotic risk. This association normalizes clot stability, and improves the efficacy of therapy, but can increase the risk of severe side effects. Due to these premises it has always raised doubts and perplexities in the clinics. We now report the data of the "FEIBA® on acquired haemophilia A Italian Registry (FAIR Registry)", a retrospective-prospective study that included 56 patients. This is the first study that assessed the clinical response of the combination of aPCC and antifibrinolytic agents in patients with acquired haemophilia A. A total of 101 acute bleeds…
Fungal Necrotizing Scleritis After Intravitreal Injection Therapy
2020
PURPOSE To report a case of infectious necrotizing scleritis secondary to Aspergillus terreus after intravitreal injection therapy. METHODS This is a case report with literature review. RESULTS A 98-year-old woman receiving intravitreal aflibercept injections for neovascular age-related macular degeneration in the left eye presented with severe pain, redness, and purulent discharge at the injection site. She was initially treated with topical fortified antibiotics, and clinical improvement was achieved, although microbial cultures showed negative results. Two months later, she presented with severe ocular pain and was diagnosed with anterior necrotizing scleritis. Scleral scrapings were col…
Steroid Receptor Expression in Endometria from Women Treated with Tamoxifen
1998
Abstract Breast cancer patients receiving tamoxifen (Tam) are at an increased risk for developing endometrial carcinomas, possibly due to the partial estrogenic effect of Tam on endometrial cells. Progestational therapy has not routinely been included in Tam regimens. It was our aim to determine the presence of estrogen receptors (ERs) and progesterone receptors (PRs) in normal and abnormal endometria from postmenopausal women with breast cancer who were treated with Tam. Standard immunohistochemical staining of ERs and PRs was performed on paraffin sections from formalin-fixed uterine curettings or hysterectomy specimens from 40 patients who had received 20–40 mg of Tam daily for a minimum…
The Patient's Anastrozole Compliance to Therapy (PACT) Program: a randomized, in-practice study on the impact of a standardized information program o…
2013
BACKGROUND Compliance and persistence are often overlooked in adjuvant breast cancer treatment. PATIENTS AND METHODS PACT was a prospective, multicenter, randomized, open, parallel-group study assessing whether educational materials (EMs) enhanced compliance with aromatase inhibitor (AI) therapy in postmenopausal women with early, hormone-receptor-positive (HR+) breast cancer. The primary end points were compliance (proportion taking ≥ 80% anastrozole) at 12 months and persistence (proportion reporting anastrozole intake during the study period). RESULTS Four thousand eight hundred and forty-four patients were randomly assigned 1:1 to receive standard therapy or standard therapy with EMs. T…
Future perspectives of the pharmacological management of diabetic dyslipidemia
2019
Introduction: Diabetic dyslipidemia is frequent among patients with type 2 diabetes mellitus (T2DM) and is characterized by an increase in triglycerides (TGs), low-density lipoprotein cholesterol (LDL-C), and small-dense (atherogenic) particles, and by a decrease in low high-density lipoprotein cholesterol (HDL-C) and apolipoprotein (Apo) A1 that are strongly related to insulin resistance. The increased flux of free fatty acids from adipose tissue to the liver aggravates hepatic insulin resistance and promotes all of aspects of the dyslipidemic state. Areas covered: Statins are the first-line agents for treatment while other lipid-lowering drugs (ezetimibe, fibrate and proprotein convertase…
Is Helicobacter pylori status relevant in the management of GORD?
2000
Summary There is growing interest in the relationship between H. pylori infection and gastro-oesophageal reflux disease (GORD). However, this relationship is complex, as yet not fully elucidated, and probably based on a multiplicity of factors. The prevalence of H. pylori infection in patients with GORD is similar, more often lower than in matched controls. There is a negative correlation between H. pylori infection and the severity of GORD. There are many hypothetical mechanisms by which H. pylori infection may protect from the development of GORD. Conversely, there are many possible mechanisms by which H. pylori infection could theoretically foster the GORD. Patients after H. pylori eradi…
Cerebellar granule-cell-specific GABAAreceptors attenuate benzodiazepine-induced ataxia: evidence from α6-subunit-deficient mice
1999
Benzodiazepine- and alcohol-induced ataxias in rodents have been proposed to be affected by the gamma-aminobutyric acid type A (GABAA) receptor alpha 6 subunit, which contributes to receptors specifically expressed in cerebellar granule cells. We have studied an alpha 6 -/- mouse line for motor performance and drug sensitivity. These mice, as a result of a specific genetic lesion, carry a precise impairment at their Golgi-granule cell synapses. On motor performance tests (rotarod, horizontal wire, pole descending, staircase and swimming tests) there were no robust baseline differences in motor function or motor learning between alpha 6 -/- and alpha 6 +/+ mice. On the rotarod test, however,…
Dietary cholic acid lowers plasma levels of mouse and human apolipoprotein A-I primarily via a transcriptional mechanism
2000
To induce dietary atherosclerosis in mice, high-fat/high-cholesterol (HF) diets are frequently supplemented with cholic acid (CA). This diet produces low plasma levels of high-density lipoprotein (HDL) and high levels of low-density lipoprotein (LDL). However, HF diets without any added CA, which more closely resemble human diets, increase levels of both HDL and LDL, suggesting that CA may be responsible for the lowering of HDL. Our aim was to examine the potential mechanism responsible for the lowering of HDL. Nontransgenic (NTg) C57BL mice and apoA-I-transgenic (apoAI-Tg) mice, with greatly increased basal apoA-I and HDL levels, were used. Mice were fed the following four diets: control (…
