Mucin 1 downregulation associates with corticosteroid resistance in chronic rhinosinusitis with nasal polyps

2013

Background A number of patients with chronic rhinosinusitis with nasal polyps (CRSwNP) are resistant to oral corticosteroids. Mucin 1 (MUC1) shows anti-inflammatory properties, and its cytoplasmic tail (CT) interacts with transcription factors, facilitating their nuclear translocation. Because glucocorticoid receptor (GR) nuclear translocation is key to the anti-inflammatory effect of corticosteroids, we hypothesized that MUC1 is involved in the effectiveness of corticosteroids. Objective To analyze the role of MUC1 in corticosteroid effectiveness in different cohorts of patients with CRSwNP and elucidate the possible mechanisms involved. Methods Seventy-three patients with CRSwNP took oral…

Das morphologische Bild der Z. glomerulosa der NNR unter chemischer Adrenostase und ACTH-Blockade

1962

An Ratten wurde tierexperimentell die Frage zu klaren versucht, welche morphologischen Veranderungen nach Applikation von Metopiron als adrenostatischer Substanz allein sowie in Kombination mit Dexamethason zur Ausschaltung der ACTH-Stimulierung an der NNR auftreten.

World Health Organization guidelines for cancer pain: a reappraisal

2005

Pain is a prevalent symptom experienced by at least 30% ofpatients undergoing an oncological treatment for metastaticdisease and by more than 70% of advanced cancer patients[1]. In 1986 the World Health Organization [2] published a setof guidelines for cancer pain management based on the three-step analgesic ladder [2]. The main aim of WHO guidelienswas to legitimize the prescribing of strong opioids, arisingfrom evidence of poor management of cancer pain, due toreluctance of health care professionals, institutions, and gov-ernment to use opioids because of fears of addition, toleranceand illegal abuse.Its application is reported to achieve satisfactory pain reliefin up to 90% of patients w…

Endocrinology: Substrate dependency of C19 conjugates in hirsute hyperandrogenic women and the influence of adrenal androgen

1995

Serum C19 conjugates, specifically 3 alpha-androstanediol glucuronide (3 alpha G), reflect peripheral androgen action through the action of 5 alpha-reductase activity. The origin of 5 alpha-reduced C19 conjugates has been controversial and it has been suggested that they are derived primarily from adrenal androgens. We examined concentrations of 3 alpha G, 3 alpha-androstanediol sulphate (3 alpha S), androsterone glucuronide (AoG) and androsterone sulphate (AoS) in 40 hirsute hyperandrogenic women. These patients were divided into four groups based upon individual, combined or normal concentrations of the adrenal androgens dehydroepiandrosterone (DHEAS) and 11 beta-hydroxy-androstenedione. …

Aldosterone biosynthesis induced by ACTH and angiotensin II in newborn rat adrenocortical cells transfected by c-EJ-Ha-ras oncogene

1991

Abstract Adrenocortical cells were obtained by fractionated trypsination of newborn rat adrenal glands and transfected with a plasmid containing the EJ T24 -Ha-ras oncogene. Isolation of adhesive cells led to a proliferative cell line with an overexpression of 21 kDa ras protein. These cells incubated with corticosterone or deoxycorticosterone as the precursor produced a high level of 18-hydroxycorticosterone and aldosterone as identified by gas chromatography- mass spectrometry. ACTH and angiotensin II increased the basal production of aldosterone nineteen-fold and six-fold respectively. Under ACTH stimulation the ratio between aldosterone and 18-hydroxycorticosterone production was 1:3. T…

Acquired haemophilia in cancer: A systematic and critical literature review

2017

Aim There is a paucity of data on the clinical presentation and management of cancer patients with acquired haemophilia (AH), we here report a systematic literature review on acquired haemophilia in the context of cancer. Methods Treatment outcomes of AH were defined as complete response (CR), partial response (PR) or no response (NR), based on inhibitor eradication, coagulation factor VIII levels and bleeding control. Reported deaths were either related to cancer or bleeding. Results Overall, 105 cases were collected and analyzed according to classification of cancer and efficacy of treatments for inhibitor and malignancy. The mean age was 68 years for both males (range 37-86 years) and fe…

Therapeutic use of hyaluronic acid fillers in the treatment of corticosteroid-induced skin and subcutaneous atrophy

2016

Corticosteroid injection–related tissue atrophy might cause permanent skin and soft tissue deformities1 due to several factors, most importantly fibroblast inhibition and decreased Type I collagen synthesis. Correction of these deformities is challenging and is mostly based on volume replacement with lipofilling or other methods. Clinical observations and research have shown that injection of stabilized hyaluronic acid (HA) induces collagen synthesis, partially restoring dermal matrix components, and eventually producing a permanent effect.2–5 Based on these data, we hypothesize that HA injections might successfully treat atrophic tissue changes caused by corticosteroid injection. We descri…

Diagnosis and novel clinical treatment strategies for pyoderma gangrenosum

2019

Introduction: Pyoderma gangrenosum (PG) is a noninfectious, reactive inflammatory neutrophilic dermatosis that is commonly associated with autoimmune and neoplastic disorders. There are emerging diagnostic tools and treatment options for PG.Area covered: The diagnosis of PG should be seriously considered when managing ulcers to avoid unnecessary medical and surgical complications with prompt and suitable treatment. There are no standardized treatment guidelines for PG, and current therapy largely depends on the severity and progression of the disease. Systemic corticosteroids, immunosuppressant therapy, and biologic agents remain mainstay therapies. In this article, we present a literature …

Pharmacological Management of Elderly Patients with Asthma–Chronic Obstructive Pulmonary Disease Overlap Syndrome: Room for Speculation?

2016

Asthma and chronic obstructive pulmonary disease (COPD) are two distinct diseases that share a condition of chronic inflammation of the airways and bronchial obstruction. In clinical settings, it is not rare to come across patients who present with clinical and functional features of both diseases, posing a diagnostic dilemma. The overlap condition has been termed asthma–COPD overlap syndrome (ACOS), and mainly occurs in individuals with long-standing asthma, especially if they are also current or former smokers. Patients with ACOS have poorer health-related quality of life and a higher exacerbation rate than subjects with asthma or COPD alone. Whether ACOS is a distinct nosological entity …
