Application of intelligent automatic segmentation and 3D reconstruction of inferior turbinate and maxillary sinus from computed tomography and analyze the relationship between volume and nasal lesion

This study aimed to propose an automatic recognition and volume calculation for the inferior turbinate and maxillary sinus by using image processing techniques. The back propagation neural network (BPNN) was used for automatic recognition of the inferior turbinate and maxillary sinus. Parametric template matching (PTM) and the sub-region similarity were used as feature inputs. The level set method (LSM) was applied to circle the contour of the inferior turbinate and maxillary sinus. The marching cubes algorithm was employed for 3D reconstruction and visualization. The volume information was obtained from the nonlinear regression curve. The accuracy and sensitivity of the automatic recognition results for inferior turbinate and maxillary sinus was 96.3 % and 95.1 %, respectively. The relationship between volume and nasal lesion has been analyzed as well.

Abstract Short-term systemic corticosteroids, also known as steroids, are frequently prescribed for adults in the outpatient setting by primary care physicians. There is a lack of supporting evidence for most diagnoses for which steroids are prescribed, and there is evidence against steroid use for patients with acute bronchitis, acute sinusitis, carpal tunnel, and allergic rhinitis. There is insufficient evidence supporting routine use of steroids for patients with acute pharyngitis, lumbar radiculopathy, carpal tunnel, and herpes zoster. There is evidence supporting use of short-term steroids for Bell palsy and ...

We present here the studies on the nasal microbiota in healthy infants, allergic rhinitis, and CRS. The results demonstrate that there are stable and unstable profiles of microbiota during infancy. Decreased diversity or an imbalance of the microbial composition could be an important factor in the development of both allergic rhinitis and CRS. We also discuss here several recent animal and human studies that demonstrate the effect of probiotics in allergic rhinitis and chronic rhinosinusitis. Results from human studies (clinical trials) have demonstrated that probiotics may be effective for allergic rhinitis, but there are...

AbstractPurpose of ReviewOccupational rhinitis (OR), an inflammatory disease of the nose, refers to any nasal symptoms reported to be work-related. The purpose of this review is to provide a current overview of the classification, diagnosis, and treatment of OR.Recent FindingsOccupational rhinitis (OR) can further be  classified into allergic or non-allergic depending on the causative agent(s) and pathogenesis. Presenting symptoms are similar to non-OR including nasal congestion, anterior and posterior rhinorrhea, sneezing, and nasal itching. Despite its high prevalence in a spectrum of workplaces, OR is under reporte...

Conclusions: Allergic rhinitis is common comorbidity of asthma that interrelated to asthma control. Identifiable allergens could be detected AR in asthma by SPT. Therefore, reduction of allergens exposure could become preventive approach for asthma patients with AR.

Introduction: Inadequate control of asthma continues to present as serious problem despite advances in our understanding of the inflammatory basis of asthma.Objective and methods: The aim of this retrospective study was to assess the asthma control using asthma control test (ACT) and to explore the factors that affects the poorly control of this disease among outpatient clinic in out center. Chi-square and Spearman tests were applied, with a 5% significance level.Results: We enrolled 195 adult patients (pts), 77% were women (n=150), with a mean age of 55y (18-86y) and mean duration of asthma of 12±7y. All pts were p...

Patients with asthma often experience nasal symptoms, from comorbid allergic rhinitis and sinusitis to nasal polyposis. We evaluated reductions in nasal symptoms as a function of baseline blood eosinophil counts (BEC) for patients in a Phase IIb study of benralizumab.

ConclusionsSM are a  common sensitization in the study population and should be included in standard skin prick test arrays. Cross sensitization to house dust mites is limited and nasal symptoms are most frequent. Nasal provocation testing is necessary to secure clinical diagnosis of allergy and further research is ne eded to evaluate the clinical relevance of the high sensitization rates found for intradermal testing.

The Journal of Allergy was launched in November 1929. The inaugural issue had 6 original articles covering asthma, ragweed pollen, bacterial allergy, a case report, sinusitis, and classification of specific sensitivities. The first editorial emphasized that the  Journal “has been launched as a medium for the presentation of papers concerning the clinical aspects of specific hypersensitivities in human beings.”1 Twenty years later, an editorial celebrating that anniversary stated, “A new era in allergy is coming into being, due to the ‘rediscover y’ that human hypersensitiveness ...

Abstract Background: Allergic rhinitis combined with chronic rhinosinusitis with nasal polyps (ARwCRSwNP) is very common clinically. Conventionally, the treatment for these patients is surgical method for CRSwNP followed by treatment with a nasal steroid spray or other antiallergic drugs to control AR. In recent years, some rhinologists introduced vidian neurectomy (VN) or posterior nasal neurectomy (PNN) into endoscopy to treat refractory AR and reported an encouraging outcome. Furthermore, we explore the control of recurrence of nasal polyps and improvement in symptoms after endoscopic PNN for the treatment of A...
