The 2015 European Thyroid Association Guidelines on diagnosis and treatment of endogenous subclinical hyperthyroidism

2014

Endogenous subclinical hyperthyroidism (SHyper) is caused by Graves' disease, autonomously functioning thyroid nodules and multinodular goitre. Its diagnosis is based on a persistently subnormal serum thyroid-stimulating hormone (TSH) level with free thyroid hormone levels within their respective reference intervals. In 2014 the European Thyroid Association Executive Committee, given the controversies regarding the treatment of Endo SHyper, formed a task force to develop clinical practice guidelines based on the principles of evidence-based medicine. The task force recognized that recent meta-analyses, including those based on large prospective cohort studies, indicate that SHyper is associ…

Immunologische Grundlagen der allergischen Spätreaktion

1965

An transferaktiven Zellen von tb-sensibilisierten Tieren sind mindestens zwei distinkte zellstandige Antikorper nachweisbar. Eine Art dieser Antikorper ist gegen Tuberkulopolysaccharid und die andere gegen Tuberkuloprotein gerichtet. Sie haben beide nach Kontakt mit dem Antigen die Fahigkeit, Komplement zu binden. Eine Cytolyse kommt sowohl durch eine zellstandig ablaufende Immunreaktion zwischen Polysaccharid-Antikorper und Tuberkuloprotein-Antikorper mit dem Antigen zustande, jedoch ist dazu nur im letzteren Falle Komplement erforderlich. Nach Kontakt mit dem Antigen ist also beim Polysacharid-Antikorper eine Komplementbindung moglich, fur eine Cytolyse aber nicht notig. Die beiden zellst…

Skimager for the objective erythema estimation in atopic dogs

2020

In this study, the severity of canine skin erythema was assessed objectively for the first time. Atopic dermatitis (AD) is a common canine inflammatory and pruritic skin disease associated with an allergic reaction to exogenous allergens. The monitoring of skin erythema over time with lesion severity scales like the CADESI-4 is an essential diagnostic and research tool, especially for clinical trials. Currently, the erythema assessment is subjective due to visual estimation. In our study, we calculated the erythema index (EI) in 14 atopic dogs based on the analysis of multispectral skin images taken with the Skimager device. The relationship between the EI and a visual erythema estimation w…

Cutaneous and Allergic reactions due to COVID‐19 vaccinations: A review

2021

ABSTRACT Introduction The pandemic caused by the novel coronavirus disease 2019 (COVID‐19) has had an unprecedented impact on the overall health and the global economy. Vaccination is currently the most dependable strategy to end the pandemic, despite the slower‐than‐hoped‐for rollout, particularly for low‐to‐middle‐income countries, and the uncertain duration of protection afforded by vaccination. The spike protein of the virus (immunodominant antigen of the virus) is the main target of the approved and candidate SARS‐CoV‐2 vaccines. This protein binds to the ACE2 receptor of the host cell, initiating the entry of the virus into the cell and the chain of subsequent events ending to Acute R…

Antigens of <i>Euparipha pisana</i> (Snail)

1988

The data obtained in this study suggest that eating <i>Euparipha pisana</i> (snail), a common food in Mediterranean countries, could give serious allergic reaction such as asthma. We describe here the identification and partial characterization of allergenic molecules form this new source. An aqueous extract of snail was obtained by homogenization in distilled water, centrifugation, dialysis and defatting with ethyl ether. Skin prick test (SPT) performed with the snail extract on 70 subjects allergic to the more common allergens of the Mediterranean area gave a SPT positivity in 61% of the subjects tested, with a mean value of histamine-equivalent prick (HEP) equal to 0.81 ± 0.2…

Fibrin Sealants in Dura Sealing: A Systematic Literature Review.

2016

BACKGROUND:Fibrin sealants are widely used in neurosurgery to seal the suture line, provide watertight closure, and prevent cerebrospinal fluid leaks. The aim of this systematic review is to summarize the current efficacy and safety literature of fibrin sealants in dura sealing and the prevention/treatment of cerebrospinal fluid leaks. METHODS:A comprehensive electronic literature search was run in the following databases: Cochrane Database of Systematic Reviews, Cochrane Central Resister of Controlled Trials, clinicaltrials.gov, MEDLINE/PubMed, and EMBASE. Titles and abstracts of potential articles of interest were reviewed independently by 3 of the authors. RESULTS:A total of 1006 databas…

IL-17 and TNF-α Are Key Mediators of Moraxella catarrhalis Triggered Exacerbation of Allergic Airway Inflammation

2017

Alterations of the airway microbiome is often associated with pulmonary diseases. For example, detection of the bacterial pathogen Moraxella catarrhalis in the upper airways is linked with an increased risk to develop or exacerbate asthma. However, the mechanisms by which M. cattarhalis augments allergic airway inflammation (AAI) remains unclear. We here characterized the cellular and soluble mediators of M. catarrhalis triggered excacerbation of AAI in wt and IL-17 deficient as well as in animals treated with TNF-alpha and IL-6 neutralizing antibodies. We compared the type of inflammatory response in M. catarrhalis infected, HDM-allergic and animals infected with M. catarrhalis at differen…

Recurrent angioedema and the threat of asphyxiation.

2009

Angioedema (also known as Quincke disease) is the name given to edema lasting 1–7 days that recurs at irregular intervals. Target organs are the skin, tongue, glottis and larynx, gastrointestinal tract, and sometimes other soft organs. The clinical symptom referred to as angioedema forms part of a variety of disease entities (Box 1, Figure 1). In Germany, according to the present author’s estimate, several thousand patients suffer from one of the forms of recurrent angioedema. Cases of sudden asphyxiation are rare, but do occur every now and again (1). This review aims to draw attention to the various clinical features of recurrent angioedema and the practical steps for dealing with it, and…
