What to Know About Severe Asthma in Kids
Asthma isn’t always a quick and easy diagnosis in children. According to a 2014 task force assembled by the American Thoracic Society and the European Respiratory Society, pediatric severe asthma can be diagnosed if a child’s symptoms require treatment with high-dose inhaled corticosteroids plus a second “controller” medication for a full year, and/or systemic corticosteroids for half a year or longer. In other words, its diagnostic criteria are based on the intractability of its symptoms. “It’s definitely a limitation when you’re defining a disease state based on how much medicine...

Shelling the myth: allergies to Iodine containing substances and risk of reaction to Iodinated contrast media
ConclusionsThere is a lack of understanding amongst local junior medical staff regarding administration of iodinated contrast media to patients with a history of allergy to iodinated substances. These misconceptions may potentiate the unnecessary usage of pre-medication and ordering of non-contrast scans in the setting of a gold-standard enhanced scan. Findings from this study suggest that there is a need for future education efforts targeted during the basic specialty training stage.

Safety of anti-inflammatory drugs in children with asthma
Purpose of review Inhaled corticosteroids (ICS) are widely used as the first-line treatment of asthma. When the disease is not controlled by standard doses of ICS, other anti-inflammatory drugs should be considered. The aim of this report is to review the main adverse events induced by anti-inflammatory drugs in children with asthma and discuss possible actions to prevent or mitigate these effects. Recent findings Proper interpretation of ICS safety studies requires knowledge of the pharmaceutical properties and delivery device systems of the different ICS available. Genetic variants affecting susceptibility to ...

Respiratory Distress Syndrome Associated with Erythrodermic Psoriasis
We report the case of a 69-year-old man with a long history of psoriasis who developed acute respiratory distress during a disease flare-up. There was no relevant past history (except for mild emphysema), known allergy, or recent treatment. Chest X-ray revealed new bilateral infiltrates, confirmed at chest computed tomography scan. Repeated cultures on aspirate of the bronchoalveolar lavage remained negative for viruses, bacteria, and parasites. Cardiac ultrasound was normal and high-dose corticosteroid therapy was initiated. Within a few days his clinical and radiological status improved significantly.Case Rep Dermatol 2021;13:83 –88

Pneumocystis jiroveci.
Abstract Pneumocystis jiroveci remains an important fungal pathogen in a broad range of immunocompromised hosts. The natural reservoir of infection remains unknown. Pneumocystis jiroveci Pneumonia (PJP) develops via airborne transmission or reactivation of inadequately treated infection. Nosocomial clusters of infection have been described among immunocompromised hosts. Subclinical infection or colonization may occur. Pneumocystis pneumonia occurs most often within 6 months of organ transplantation and with intensified or prolonged immunosuppression, notably with corticosteroids. Infection is also common during ne...

Elevated serum IgE, oral corticosteroid dependence and IL-17/22 expression in highly neutrophilic asthma
Information on the clinical traits associated with bronchial neutrophilia in asthma is scant, preventing its recognition and adequate treatment. We aimed to assess the clinical, functional and biological features of neutrophilic asthma and identify possible predictors of bronchial neutrophilia. The inflammatory phenotype of 70 mild-to-severe asthma patients was studied cross-sectionally based on the eosinophilic/neutrophilic counts in their bronchial lamina propria. Patients were classified as neutrophilic or non-neutrophilic. Neutrophilic asthma patients (neutrophil count cut-off: 47.17 neutrophils·mm–2;...

Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...

Systemic Lupus Erythematosus With Isolated Psychiatric Symptoms and Antinuclear Antibody Detection in the Cerebrospinal Fluid
Conclusion: Some patients with psychiatric syndromes and increased ANA titers may suffer from psychiatric variants of SLE, even if the American College of Rheumatology criteria for SLE are not met. Whether the psychiatric symptoms in our patient represent a prodromal stage with the later manifestation of full-blown SLE or a subtype of SLE with isolated CNS involvement remains unclear. Regardless, early diagnosis and initiation of immunosuppressive treatment are essential steps in preventing further disease progression and organ damage. Intrathecal ANAs with extractable nuclear antigen differentiation may be a more sensitiv...

Oligonucleotides —A Novel Promising Therapeutic Option for IBD
Conclusions In this review, we focused on recent and past approaches to test the therapeutic efficacy of oligonucleotide based therapies in IBD. The combining mechanistic mode of oligonucleotide based therapeutics is a targeted action on specific pro-inflammatory molecules, which are over activated in IBD patients and contribute significantly to disease pathogenesis. The proposed high selectivity of the agents is derived from its mode of action, that aims to specifically block certain inflammatory molecular patterns, without a general systemic effect on other molecular targets. It would be important for each oligonucleot...

Incidence and Outcome of Invasive Fungal Diseases in Children With Hematological Malignancies and/or Allogeneic Hematopoietic Stem Cell Transplantation: Results of a Prospective Multicenter Study
Conclusion: This prospective multicenter study provides information on the current incidence and outcome of IFD in the real life setting. Practice variation between the centers may help to ultimately improve antifungal management in children at highest risk for IFDs. Introduction Available data on the incidence and outcome of invasive fungal diseases (IFD) in children treated for a hematological malignancy or undergoing allogeneic hematopoietic stem cell transplantation (HSCT) are mostly based on single site, retrospective studies or on studies performed prior to the availability of newer compounds such as broad-sp...

The Study of Dried Ginger and Linggan Wuwei Jiangxin Decoction Treatment of Cold Asthma Rats Using GC –MS Based Metabolomics
Conclusion In this study, serum and urine metabolites identified by GC–MS and general pharmacodynamic evaluation (morphological observation, histopathology, inflammatory factors, and visceral indices) were used to compare the effects of GJ and LGWWJX decoctions on cold asthma. Significant metabolic abnormalities were observed for 37 metabolites (15 in serum, 22 in urine) in rats with cold asthma. These altered metabolites might be potential biomarkers or therapeutic targets during development of cold asthma. Furthermore, pathway analysis demonstrated that pathways associated with energy metabolism and oxidative str...

Qingpeng Ointment Ameliorates Inflammatory Responses and Dysregulation of Itch-Related Molecules for Its Antipruritic Effects in Experimental Allergic Contact Dermatitis
Conclusion Via a HPLC system and a BATMAN-TCM platform, for the first time we performed detailed HPLC fingerprint analysis and network pharmacology studies of QP ointment. By in-depth animal and molecular analysis, we identified a number of chronic dermatitis-associated Th1/2 cytokines, itch mediators, and cellular signaling pathways in the skin, DRG and serum for QP to treat the inflammation and chronic itch associated with ACD. Our data clearly suggested, upon stimulation, cytokines and itch-related mediators are released from the skin and neuronal tissues, and QP could effectively work on both the skin and sensory neur...
