Nasal Nitric Oxide May Not Differentiate Primary Ciliary Dyskinesia from Certain Primary Immunodeficiencies.

Pediatr Pulmonol 2022 May 20. Epub 2022 May 20.

Division of Pediatric Pulmonary, Allergy and Sleep Medicine. Riley Hospital for Children, Indiana University School of Medicine, Indianapolis, Indiana.

The diagnosis of primary ciliary dyskinesia (PCD) is made through a combination of clinical features supported by a panel of diagnostic tests. Our cases highlight the similarities in the clinical presentation of patients with the specific immunodeficiency activated phosphatidylinositol 3-kinase delta syndrome 1 (APDS1 or PIK3CD-Related Disorder) and PCD. We highlight the importance of repeating nasal nitric oxide testing (nNO) when PCD has not been confirmed by genetic or ciliary electron micrograph (EM) analysis in the setting of an expanded suppurative lung disease differential that includes considerations for immunodeficiency as well as PCD.

Cell Immunol 2022 May 14;376:104536. Epub 2022 May 14.

Department of Immunology, School of Basic Medical Sciences, Capital Medical University, Beijing, China. Electronic address:

Respiratory tract infection early in life plays a significant role in the pathogenesis of asthma. In the present study we examine, using a murine surrogate, the effects of early life respiratory infection with Streptococcus pneumoniae (SP) on adult asthma induced by sensitisation and exposure to house dust mite (HDM) allergen. Mice (one week old) were infected with SP, then 3 weeks later sensitised to HDM emulsified with Al (OH)3 intraperitoneally and challenged intranasally with same allergen for up to a further 5 weeks to establish the asthma surrogate.

MERS-CoV endoribonuclease and accessory proteins jointly evade host innate immunity during infection of lung and nasal epithelial cells.

Proc Natl Acad Sci U S A 2022 May 20;119(21):e2123208119. Epub 2022 May 20.

Department of Microbiology, University of Pennsylvania, Philadelphia, PA 19104.

SignificanceMiddle East respiratory syndrome coronavirus (MERS-CoV) causes highly lethal respiratory disease. MERS-CoV encodes innate immune antagonists, including accessory proteins NS4a and NS4b, unique to the merbeco lineage of betacoronaviruses, and the nsp15 protein endoribonuclease (EndoU), conserved among all coronaviruses. While mutation of each antagonist protein alone has little effect on innate immunity, infections with recombinant MERS-CoVs with mutations of EndoU in combination with either NS4a or NS4b activate innate signaling pathways and are attenuated for replication.

Using of panoramic and posteroanterior cephalometric radiographs to identify the optimal nasal passage for nasotracheal intubation.

Niger J Clin Pract 2022 May;25(5):647-652

Department of Oral and Maxillofacial Surgery, Gazi University Faculty of Dentistry, Çankaya, Ankara, Turkey.

Background And Aim: Selecting the optimum nasal passage for nasotracheal intubation is quite important in the maxillofacial surgeries for the success of intubation and the reduction of potential complications such as nasal mucosal laceration, epistaxis, avulsion of the inferior and middle turbinates, and septal laceration.

Materials And Methods: The present study evaluates standard panoramic radiographs (PR) and posteroanterior cephalometric radiographs (PACR) to determine the optimal nasal passage for nasotracheal intubation and compares the results with those of routine anesthesiological occlusion and spatula tests (ST). The results of occlusion tests (OT), ST, and radiological assessments of 60 patients prior to nasotracheal intubation were compared with the nasal endoscopic assessment results, and complications were evaluated.

The detection and phylogenetic analysis of equine herpesviruses 1, 4 and 5 identified in nasal swab samples of asymptomatic horses from Serbia and Bosnia and Herzegovina.

Vet Ital 2021 Dec 31;57(4):265-274. Epub 2021 Dec 31.

Faculty of Veterinary Medicine, University of Belgrade.

Nasal swabs originating from 112 apparently clinically healthy and unvaccinated horses of different age, breed and from diverse rearing conditions from Serbia and Bosnia and Herzegovina were examined for the presence of equine herpesviruses 1, 4 and 5 using multiplex nested PCR (Mn‑PCR) and virus isolation. The detected viruses were subsequently characterised by gB gene nucleotide sequencing and their phylogenetic analysis was performed. The infections with EHV‑1, EHV‑4, and EHV‑5 in the examined horse populations are apparently chronic, subclinical and persistent, whilst the shedding of EHV‑1 and EHV‑5 was confirmed by their successful isolation.

A unique form of collective epithelial migration is crucial for tissue fusion in the secondary palate and can overcome loss of epithelial apoptosis.

Development 2022 May 20. Epub 2022 May 20.

Department of Cell and Tissue Biology; University of California San Francisco; San Francisco, CA, 94143, USA.

Tissue fusion frequently requires the removal of an epithelium intervening distinct primordia to form one continuous structure. In the mammalian secondary palate, a midline epithelial seam (MES) forms between two palatal shelves and must be removed to allow mesenchymal confluence. Abundant apoptosis and cell extrusion support their importance in MES removal. Read More
