The Clinical Significance of Nasal Nitric Oxide Concentrations in Preschool Children with Nasal Inflammatory Disease.

Allergic rhinitis is an allergic inflammation of the nasal airways, and chronic rhinosinusitis is an inflammation of the paranasal sinuses. It can be induced by infection, allergy, or autoimmune problems. Diagnosis of these two diseases is made primarily based on clinical symptoms, allergen test, and imaging. The allergen test is invasive and expensive. The imaging test is harmful to children. Measurement of nasal nitric oxide (NNO) was noninvasive, without radiation, and inexpensive. This study was to eval...

An intraorbital arteriovenous fistula presenting with impaired extraocular movement following a provocation test at the third segment of the ophthalmic artery.

Distal catheterization in the ophthalmic artery beyond the origin of the central retinal artery has been attempted to avoid visual complications in cases of transarterial embolization (TAE). Although avoiding visual complications is important, extraocular complications have been rarely reported and discussed. Here, we report a case of an intraorbital arteriovenous fistula (AVF) presenting with impaired extraocular movement following a provocation test and discuss the potential risks associated with TAE at t...

CSF volume provocation maneuvers during lumbar puncture as a possible predictive tool for diagnosing spontaneous intracranial hypotension.

Spontaneous intracranial hypotension (SIH) is a pathologic state of low CSF volume caused by a CSF to venous fistula or CSF leak. It is diagnosed based on symptoms, imaging, and CSF pressure but is often a diagnostic challenge because no single test is highly sensitive. Physician-induced changes in CSF volume may result in changes in patient symptoms, as has been shown with idiopathic intracranial hypertension (IIH). The purpose of this study is to determine the sensitivity of CSF volume provocation maneuve...

Bronchodilation test with inhaled salbutamol versus bronchial methacholine challenge to make an asthma diagnosis: do they provide the same information?

Methacholine bronchial challenge and bronchodilation to salbutamol are key tests in clinical practice to make asthma diagnosis.

Coronary artery dissection due to severe coronary vasospasm during ergonovine provocation test.

Drug provocation testing: risk stratification is key.

This review aims to describe current best practice and recent advances in the use of risk stratification as a tool for drug provocation testing (DPT). In particular, we focus on the testing of unsubstantiated penicillin allergy labels.

Neural correlates of symptom provocation in pediatric obsessive-compulsive disorder.

OBSESSIVE-COMPULSIVE DISORDER: (OCD)-affected adults and children exhibit three to four symptom dimensions with distinct but overlapping neural correlates. No symptom provocation behavioural or imaging study has examined all symptom dimensions in a pediatric OCD sample. METHOD: Clinically diagnosed pediatric OCD-affected participants (n = 25) as well as age, gender and Tanner pubertal stage-matched healthy controls (HCs; n = 24) (total sample: mean age = 14.77 ± 2.93 years; age range = ...

Data-driven step doses for drug provocation tests to non-steroidal anti-inflammatory drugs.

Hypersensitivity to non-steroidal anti-inflammatory drugs (NSAIDs) are of great concern because they are frequently encountered in daily clinical practice. Drug provocation tests (DPT) are particularly needed for NSAIDs.

Predictive factors for a shortened methacholine challenge protocol in children.

Although the methacholine challenge test is useful in the diagnosis of asthma, it is time-consuming in children. While protocols that quadruple methacholine concentrations are widely used in adults to shorten testing time, this has not been evaluated in children. Studies have not identified predictors associated with the safe use of a quadrupled concentration protocol.

Children mono-sensitized to Can f 5 show different reactions to male- and female dog allergen extract provocation: a randomized controlled trial.

Dog dander consists of several allergenic molecules including Can f 5, which is a protein expressed in the prostate of male dogs.


The aim of our study was a comparative description of the state of bronchial sensitivity to nonspecific stimuli in respiratory asymptomatic children and children with bronchial asthma. We investigated a total of 242 children aged between 7 and 14 years. The group of respiratory asymptomatic children included 100 examined and 142 had an established diagnosis of atopic bronchial asthma at the I, II, and III stages in the phase of remission. The study was conducted in accordance with the principles of bioethic...

Cold air exercise screening for exercise induced bronchoconstriction in cold weather athletes.

Exercise Induced Bronchoconstriction (EIB) prevalence in cold weather athletes is high. Currently, no standardized cold air exercise provocation test exists. Thus we aimed to determine EIB prevalence using a Cold Air Test (CAT; 5 km outdoor running; -15 °C) compared to the most common EIB screen the Eucapnic Voluntary Hyperpnea (EVH) test in cold weather athletes. Sixteen (9 male; 20-35 years old) cold weather athletes completed EVH 72 hours before CAT. Spirometry, Fractional Expired Nitric Oxide (FE...

Exhaled nitric oxide can't replace the methacholine challenge in suspected pediatric asthma.

In adults, measurement of FNO has been recently suggested as a substitute for the methacholine challenge test (MCT) for diagnosis of asthma. This study aimed to evaluate whether FeNO is a substitute for MCH also in children with suspicious asthma.

ymmetrical drug-related intertriginous and flexural exanthema due to clindamycin.

Systemic drug exposure can produce a skin reaction consisting of symmetrical erythema involving the gluteal and intertriginous areas in the absence of systemic involvement. ymmetrical drug-related intertriginous and flexural exanthema (SDRIFE) occurs after systemic exposure to a drug in which the patient was not previously sensitised, either in the first dose or after several doses. The mechanism of SDRIFE is unknown but is hypothesised to be the result of a delayed hypersensitivity response resulting in a ...

Myocardial bridging is an independent predictor of positive spasm provocation testing by intracoronary ergonovine injections: a retrospective observational study.

The relationship between myocardial bridging (MB) and coronary spasms during spasm provocation testing (SPT) remains unclear. We aimed to investigate whether MB was correlated with the SPT by ergonovine (ER) injections in a retrospective observational study. Of the 3340 patients who underwent a first coronary angiography, 166 underwent SPT using ER injections and were divided into 2 groups: MB(+) (n = 23), and MB(-) (n = 143). MB was defined as an angiographic reduction in the diameter of the corona...

Low-pressure Lumbar Provocation Discography According to Spine Intervention Society/International Association for the Study of Pain Standards Does Not Cause Acceleration of Disc Degeneration in Patients with Symptomatic Low Back Pain: A 7 Year Matched Cohort Study.

MINI: This study investigated if low-pressure provocation discography results in accelerated disc degeneration, disc disruption, and disc herniation at long-term follow-up in patients with low back pain in clinical practice. The results demonstrated disc degeneration, disc disruption, and disc herniation at a similar rate to corresponding discs in matched-control patients.

A Multicenter retrospective study on hypersensitivity reactions to Non-Steroidal Anti-inflammatory Drugs (NSAIDs) in children: a report from the European Network on Drug Allergy (ENDA) group.

Diagnosis of hypersensitivity (HS) reactions to non-steroidal anti-inflammatory drugs (NSAIDs) in children is complex. The real prevalence of NSAIDs HS remains unknown because a drug provocation test (DPT) is not always performed with the culprit NSAID.
