Asthma

Asthma is the most common chronic illness and is one of the most common medical emergencies in children. Progressive refractory near-fatal asthma requiring intubation and mechanical ventilation can lead to death. Extracorporeal membrane oxygenation (ECMO) can provide adequate gas exchange during acute respiratory failure although data on outcomes in children requiring ECMO support for status asthmaticus is sparse with one study reporting survival rates of nearly 85% with asthma being one of the best outcome subsets for patients with refractory respiratory failure requiring ECMO support...

BACKGROUND: Asthma with Aspergillus sensitization (ASA) and allergic bronchopulmonary aspergillosis (ABPA) are distinct clinical conditions, with different management strategies. OBJECTIVE: To determine the utility of the basophil activation test (BAT) in differentiating between asthmatic subjects with and without ABPA. METHODS: We performed the BAT using flow cytometry for the basophil activation markers CD63, CD193, and CD203c in consecutive subjects with unsensitized asthma (UA), ASA, and ABPA...

BACKGROUND: Despite being largely preventable, many occupational diseases continue to be highly prevalent and extremely costly. Effective strategies are required to reduce their human, economic, and social impacts. METHODS: To better understand which approaches are most likely to lead to progress in preventing noise-related hearing loss, occupational contact dermatitis, occupational cancers, and occupational asthma, we undertook a scoping review and consulted with a number of key informants...

The world health organization reports that 80% of the population living within the developing countries depends basically on traditional medicine for his or her primary health care. Quite half the entire world's population still depends entirely on plants for medicines, and plants provides the active ingredients to the most traditional medical products. Hamelia patens that belong to the family Rubiaceae, is mainly found in tropical and sub-tropical areas. It is used in folk medicine against a wide range of diseases such as athlete's foot, skin problems, insect sting, psychiatric disorder, rheumatism, headache, asthma, dysentery, menses, ovarian and uterine disorders...

BACKGROUND: This study was aimed to evaluate the beneficial role of inhalation budesonide(BUD) in improving the pulmonary functions, and reducing the hospital admission rate, worsening of asthma and commonly encountered adverse events in pediatric asthma. METHODS: The electronic search was performed using PubMed, Scopus, CENTRAL (Cochrane Central Register of Controlled Trials) and Google scholar databases to identify the randomized control trials(RCTs). RESULTS: 21 RCTs involving 12,787 subjects were included...

Background: Higher socioeconomic status (SES) indicators such as educational attainment and income reduce the risk of chronic lung diseases (CLDs) such as Chronic Obstructive Pulmonary Disease (COPD), emphysema, chronic bronchitis, and asthma. Marginalization-related Diminished Returns (MDRs) refer to smaller health benefits of high SES for marginalized populations such as racial and ethnic minorities compared to the socially privileged groups such as non-Hispanic Whites. It is still unknown, however, if MDRs also apply to the effects of education and income on CLDs...

We describe the case of a 13-year-old girl with atopic dermatitis (AD) and severe asthma that presented to the Dermatology clinic with a pruritic skin rash, which appeared concomitantly to common cold symptoms. On examination, there are erythematous, umbilicated papules and vesicles, some with erosions and crusting, surrounding the mouth and areolas; a few lesions are visible on the forearms. The mucous membranes were unaffected, the patient was afebrile, and no lymphadenopathies were present. A diagnosis of eczema herpeticum (HE) was suspected, and a direct fluorescent antibody test was positive for herpes simplex virus...

Enteritis associated with systemic lupus erythematosus (SLE) is a rare and unusual manifestation of the gastrointestinal (GI) consequences of SLE itself. Complications of the enteritis component include mesenteric vasculitis, intestinal pseudo-obstruction, and protein-losing enteropathy. Lupus enteritis is very responsive to treatment with pulse steroids in almost 70% of the patients, but it is critical to diagnose it early to prevent devastating organ damage. The case describes a 21-year-old Caucasian female with a past medical history of uncomplicated laparoscopic appendectomy (one month prior to the time of presentation), major depressive disorder, asthma, iron deficiency anemia, pelvic inflammatory disease secondary to sexually transmitted Chlamydia trachomatis infection, and SLE (diagnosed two weeks prior to presentation)...

Our understanding of the general principles of the polymodal regulation of transient receptor potential (TRP) ion channels has grown impressively in recent years as a result of intense efforts in protein structure determination by cryo-electron microscopy. In particular, the high-resolution structures of various TRP channels captured in different conformations, a number of them determined in a membrane mimetic environment, have yielded valuable insights into their architecture, gating properties and the sites of their interactions with annular and regulatory lipids...

PDE4 inhibitors can suppress a variety of inflammatory cell functions that contribute to their anti-inflammatory actions in respiratory diseases like chronic obstructive pulmonary disease (COPD) and asthma. The systemically delivered PDE4 inhibitor roflumilast has been approved for use in a subset of patients with severe COPD with chronic bronchitis and a history of exacerbations. Use of systemically delivered PDE4 inhibitors has been limited by systemic side effects. Inhaled PDE4 inhibitors have been considered as a viable alternative to increase tolerability and determine the maximum therapeutic potential of PDE4 inhibition in respiratory diseases...

Aspergillus fumigatus is a serious cause of disease in immune-deficient patients and in those with pulmonary malfunction (e.g., cystic fibrosis (CF), asthma). Atorvastatin is a member of the statin drug family, which are the main therapeutic agents used to decrease high serum cholesterol levels by inhibiting (HMG-CoA) reductase enzyme. The aim of the work presented here was to analyse the antifungal activity of atorvastatin and assess its effect on the virulence of A. fumigatus . Atorvastatin demonstrated strong antifungal activity and reduced the growth and viability of A...

BACKGROUND: The overcrowding of hospital outpatient and emergency departments (OEDs) due to chronic respiratory diseases in certain weather or under certain environmental pollution conditions results in the degradation in quality of medical care, and even limits its availability. OBJECTIVE: To help OED managers to schedule medical resource allocation during times of excessive health care demands after short-term fluctuations in air pollution and weather, we employed machine learning (ML) methods to predict the peak OED arrivals of patients with chronic respiratory diseases...

OBJECTIVES: Literature assessing the effects of policies aimed at reducing traffic-related air pollution is scarce. The aims of this study were to evaluate the expected impacts, in terms of air quality and health effects, of various hypothetical low-emission zone (LEZ) scenarios in Greater Paris for a planned intervention in 2018/2019 which combine two different perimeters and two levels of vehicles ban, and to assess those impacts according to the socioeconomic status (SES) of the population...

In the event of a global infectious pandemic, drastic measures may be needed that limit or require adjustment of ambulatory allergy services. However, no rationale for how to prioritize service shut down and patient care exists. A consensus-based ad-hoc expert panel of allergy/immunology specialists from the United States and Canada developed a service and patient prioritization schematic to temporarily triage allergy/immunology services. Recommendations and feedback were developed iteratively, using an adapted modified Delphi methodology to achieve consensus...

Asthma is the most prevalent respiratory disease worldwide and it can affect people of all ages and is potentially fatal. Today, maintenance treatments are available that are effective in most patients, yet a significant proportion have poorly controlled disease, despite the resources on offer. This document, endorsed by members of the Spanish medical societies involved in the treatment of asthma, is intended to draw the attention of society and professionals to this problem in Spain. It focuses on the clinical, diagnostic and therapeutic aspects of asthma, and proposes some actions for improvement as regards patients and healthcare professionals which, in view of the current results arising from inadequate asthma control, might be beneficial to improve outcomes for both patients and public health...

PURPOSE: Chronic and persistent exposure to negative stress can lead to adverse consequences on health. Particularly, psychosocial factors were found to increase the risk and outcome of respiratory diseases like asthma. Glucocorticoids (GCs) are the most efficient anti-inflammatory therapy for asthma. However, a significant proportion of patients don't respond adequately to GC administration. GC sensitivity is modulated by genetic and acquired disease-related factors. Additionally, it was proposed that endogenous corticosteroids may limit certain actions of synthetic GCs, contributing to insensitivity...

The innate lymphoid cell (ILC) family consists of natural killer (NK) cells, helper-like lymphoid cells (ILC1s, ILC2s, and ILC3s), and lymphoid tissue inducer (LTi) cells. Helper-like ILCs are considered the innate counterpart of T-helper cells because of similarities in their cytokine output and expression of key transcription factors. ILCs provide and regulate innate immune functions before the development of adaptive immunity. They are involved in host defense against pathogens, inflammation, tissue repair, and metabolic homeostasis...
