RESUMO
BACKGROUND & AIMS: Nasal obstruction caused by nasal septal deviation is very bothersome and, therefore, can affect the patient's emotional state. However, little is known about the effect of nasal septal deviation (NSD) on the neuropsychiatric aspects of patients. Therefore, this study aims to verify the higher incidence of anxiety, depression, and migraine in patients diagnosed with NSD compared to general populations using big data. METHODS: This retrospective cohort study collected subjects from the Korean National Health Insurance Service (NHIS) database. Adjustments were made to minimize the confounding of variables for age, sex, residence type, income levels, hypertension, diabetes, dyslipidemia, rhinitis, and chronic rhinosinusitis between the two groups. The primary endpoint of this study was newly diagnosed anxiety, depression, and migraine between January 2009 and December 2018. Kaplan-Meier survival curves, logarithmic rank test, and Cox proportional regression test were used for statistical analysis. RESULTS: Among a total of 135,769 subjects in the NHIS database, 48,495 patients with NSD (NSD group) and 54,475 control subjects (control group) were selected. Patients with NSD had an increased risk of anxiety, depression, and migraine compared to the control group. In the NSD group, the adjusted hazard ratios (HR) were 1.236 (95% CI, 1.198-1.276) for anxiety, 1.289 (95% CI, 1.238-1.343) for depression, and 1.251 (95% CI, 1.214-1.290) for migraine. CONCLUSION: NSD is associated with a higher incidence of anxiety, depression, and migraine. Therefore, it is suggested that physicians carefully consider psychoneurological distress and employ therapeutic strategies to minimize these conditions.

Warfarin is a synthetic oral anticoagulant that crosses the placenta and can lead to a number of congenital abnormalities known as fetal warfarin syndrome. Our aim is to report on the follow-up from birth to age 8 years of a patient with fetal warfarin syndrome. He presented significant respiratory dysfunction, as well as dental and speech and language complications. The patient was the second child of a mother who took warfarin during pregnancy due to a metallic heart valve. The patient had respiratory dysfunction at birth. On physical examination, he had a hypoplastic nose, pectus excavatum, and clubbing of the fingers. Nasal fibrobronchoscopy showed upper airway obstruction due to narrowing of the nasal cavities. He underwent surgical correction with Max Pereira graft, zetaplasty, and osteotomies for the piriform aperture. At dental evaluation, he had caries and delayed eruption of the upper incisors. Speech and language assessment revealed high palate, mouth breathing, little nasal patency, and shortened upper lip. Auditory long latency and cognitive-related potential to auditory stimuli demonstrated functional changes in the cortical auditory pathways. We believe that the frequency of certain findings observed in our patient may be higher in fetal warfarin syndrome than is appreciated, since a significant number result in abortions, stillbirths, or children evaluated in the first year of life without a follow-up. Thus, a multidisciplinary approach and long-term monitoring of these patients may be necessary.

Activity-dependent survival of olfactory sensory neurons (OSNs) may allow animals to tune their olfactory systems to match their odor environment. Activity-dependent genes should play important roles in this process, motivating experiments to identify them. Both unilateral naris occlusion of mice for 6 days and genetic silencing of OSNs decreased S100A5, Lrrc3b, Kirrel2, Slc17a6, Rasgrp4, Pcp4l1, Plcxd3, and Kcnn2 while increasing Kirrel3. Naris occlusion also decreased Eml5, Ptprn, and Nphs1. OSN number was unchanged and stress-response mRNAs were unaffected after 6 days of naris occlusion. This leaves odor stimulation as the most likely cause of differential abundance of these mRNAs, but through a mechanism that is slow or indirect for most because 30-40 min of odor stimulation increased only 3 of 11 mRNAs decreased by naris occlusion: S100A5, Lrrc3b, and Kirrel2. Odorant receptor (OR) mRNAs were significantly more variable than the average mRNA, consistent with difficulty in reliably detecting changes in these mRNAs after 6 days of naris occlusion. One OR mRNA, Olfr855, was consistently decreased, however. These results suggest that the latency from the cessation of odor stimulation to effects on activity-dependent OSN survival must be a week or more in juvenile mice.

Unilateral naris occlusion has been the method of choice for effecting stimulus deprivation in studies of olfactory plasticity. Early experiments emphasized the deleterious effects of this technique on the developing olfactory system while more recent studies have pointed to several apparently "compensatory" responses. However, the evidence for deprivation-induced compensatory processes in olfaction remains fragmentary. High-throughput methods such as microarray analysis can help fill the deficits in our understanding of naris occlusion as a mode of stimulus deprivation. Here we report for young adult mice the effects of early postnatal naris occlusion on the olfactory mucosal transcriptome using microarray analysis with RT-PCR confirmation. The transcripts of key genes involved in olfactory reception, transduction, and transmission were up-regulated in deprived-side olfactory mucosa, with opposite effects in non-deprived-side mucosa, compared to controls. Results support the hypothesis that odor environment triggers a previously unknown homeostatic control mechanism in olfactory receptor neurons designed to maximize information transfer.

OBJECTIVE: Microarray technique is a useful tool to identify functional gene candidates. In this study, we evaluated the gene expression profiles in the olfactory bulbs of normal rats and naris-occluded rats using the gene microarray technique. STUDY DESIGN AND METHODS: To induce atrophic change in the olfactory bulb, we performed a unilateral nasal obstruction by electronic cauterization on postnatal day 1 rats. Differential gene expression profiles of the nasal obstruction group and the normal control group at postnatal day 35 were analyzed with a DNA microarray. RESULTS: Microarray revealed 41 genes that were upregulated at least 2-fold in the nasal obstruction group compared with the control group. Among these upregulated genes, increased expression levels of 20 functional genes were confirmed by semiquantitative reverse transcription-polymerase chain reaction. CONCLUSION: This study examines candidate genes associated with the development, apoptosis, and signal transduction of the olfactory bulb. These results may explain the fact that blockage of airflow by inflammation and nasal polyps causes deprivation of olfactory functions in vivo.

In airway tissues, it has been suggested that tachykinins act as the transmitter for afferent sensory nerves which respond to various irritants and may be involved in airway allergic reactions. Three classes of tachykinin receptor have been recognized, denoted NK1, NK2 and NK3, which exhibit preferential affinity for substance P, neurokinin A and neurokinin B, respectively. We used molecular probes to study the gene expression and distribution of NK2 receptor in human nasal mucosa. Total RNA was isolated from human nasal mucosa and NK2 receptor mRNA was detected in these tissues using reverse transcriptase polymerase chain reaction (RT-PCR). For an in situ hybridization study of human nasal mucosa, we utilized the PCR directly to incorporate a T7 RNA polymerase promoter sequence onto the NK2 receptor cDNA, and these PCR products were used as the DNA template for producing digoxigenin-labeled antisense and sense RNA probes. These studies revealed that NK2 receptor mRNA was expressed in blood vessels. The results suggest a primary role for neurokinin A in the form of vascular responses in the upper respiratory tract.

In a meaningful proportion of cases, CBAVD has been recognised as a probable consequence of cftr gene mutations. This lead to a further enlargement of the spectrum of clinical pictures due to "cftr deficiency". More recently, the identification of a polymorphism in intron 8 regulating the level of correct cftr transcription, shed new light on the genotype-fenotype correlation of cftr mutations. Unfortunately, little information is still available on the clinical manifestations of CBAVD other than infertility. History, clinical picture, sweat test and genotype were carefully evaluated in a series of 21 patients affected by CBAVD, selected on the basis of otherwise unexplained obstructive azoospermia. History collection was especially addressed to respiratory symptoms. Family history was always negative for CF. Nevertheless, personal history showed respiratory symptoms in 18 cases (86%) 9/21 (43%) patients suffered from chronic sinusitis and one of these had had a pneumothorax. Other 9 (43%) patients had chronic nasal obstruction, due to recurrent nasal poliposis in two cases. Sweat test was clearly abnormal in 15/21 (71%) and borderline in the remaining 6 patients (29%). Genetic analysis allowed detection of one mutation in 15/21 patients (71%). Our data show that respiratory symptoms may be present in CBAVD patients, so that CBAVD cannot be merely considered a "genital form" of CF.

We describe a child who has central diabetes insipidus associated with congenital nasal pyriform aperture stenosis without any apparent anterior pituitary dysfunction. This association further strengthens the concept that congenital nasal pyriform aperture stenosis may be a microform of holoprosencephaly.

We describe two female infants with congenital nasal pyriform aperture stenosis and severe pituitary insufficiency. The anterior pituitary gland was undetectable with magnetic resonance imaging. Consanguinity of parents in both cases suggests autosomal recessive inheritance of this disorder. An early fetal developmental defect may explain this syndrome, which affects midline craniofacial structures. In patients with congenital pyriform aperture stenosis, magnetic resonance imaging of the brain and endocrine investigations should be performed for rapid diagnosis and treatment of the latter to avoid major neurologic complications.

Eosinophils and their products are known to cause hyperreactivity and swelling of the nasal mucosa in subjects with nasal allergy. Interleukin-5 (IL-5) not only induces differentiation and proliferation of immature eosinophils but also causes mature cells to accumulate and activate. This study shows that IL-5 is actually produced in the human nasal mucosa by antigen challenge, and it further investigates the changes in the amount of IL-5 in nasal lavage fluids after antigen challenge. Expression of mRNA for IL-5 in nasal mucosa was investigated using the reverse transcription-polymerase chain reaction (RT-PCR) and Southern blot analysis. Among the 4 subjects with nasal allergy examined in this study, expression of mRNA for IL-5 was observed in 2 prior to antigen challenge; within 6 h after antigen challenge it was seen in 3 subjects. We also found that the amount of IL-5 in the nasal lavage fluids obtained consecutively after antigen challenge increased predominantly in the late phase, and that the number of eosinophils in the IL-5 positive group was significantly higher than that in the IL-5 negative group. These results strongly suggest that IL-5 contributes to the recruitment of eosinophils in the nasal mucosa of the subjects with nasal allergy.
