IgE-mediated allergy plays a well-established role in both nasal and pulmonary diseases due to the common epithelium and shared mediator responses of the upper and lower airways. This "unified airway" concept has also been described in other sites within the head and neck that contain similar respiratory mucosa: the middle ear and the larynx. This review will highlight the data suggesting a role for IgE-mediated allergic disease in chronic laryngopharyngeal and middle ear disease and the role for allergy testing to aid in diagnosis and treatment of these disorders...

Despite the growing number of rhinoplasty procedures being performed on Indian patients, there is a very limited body of literature regarding nuances of the Indian rhinoplasty. The authors review the spectrum of nasal phenotypes that fall under the category of the Indian nose; goals of rhinoplasty in these patients; operative techniques that can be used to address them; and, importantly, the specific pitfalls to be avoided in these groups.

: The present study was undertaken to determine whether a more aesthetically acceptable nostril shape could be created by manipulating the dilator naris muscles. Patients who had round or horizontally shaped nostrils were treated by resecting the dilator naris muscle to attenuate the dilating and lateral pulling effect of the muscles. The resected muscle segments were inserted into the nasal tip area to project the nasal tip. Manipulating the dilator muscle shaped the nostril more vertically and enhanced nasal tip augmentation...

BACKGROUND: Nasal inflammatory disorders such as chronic rhinosinusitis and nasal polyp are among the most prevalent complications with high socioeconomic costs. Vascular Endothelial Growth Factor (VEGF) plays a key role in angiogenesis and cell proliferation. In the present study the effect of VEGF on the development and prognosis of chronic rhinosinusitis and nasal polyp was investigated. METHODS: This cross sectional study was performed on the nasal histological specimens of two groups of patients suffering from nasal polyp or chronic rhinosinusitis, and the expression of VEGF in the two groups was compared immunohistochemically...

The reconstruction of a full-thickness defect of the distal third of the nose requires the restoration of all three anatomical layers. A practical method for three-layer reconstruction of the lower third of the nose and the long-term results of this technique are presented herein. A combined reconstruction technique was utilized, including a reverse subcutaneous pedicled nasolabial flap to restore the nasal mucosa, an auricular cartilage graft for structural support, and a forehead flap for cutaneous coverage of the defect...

Allergic rhinitis (AR) is a common chronic inflammatory condition of the nasal mucosal tissue. Platycodin D (PLD), a triterpenoid saponin isolated from the root of Platycodon grandiflorum, has anti-inflammatory effects in a mouse model of allergic asthma. However, the anti-inflammatory effects of PLD in the nasal mucosa have not been deeply investigated. The objective was to investigate the effect of PLD on inflammatory cytokines and mucus production from nasal epithelial cells. Our study showed that PLD inhibited the levels of granulocyte-macrophage colony-stimulating factor (GM-CSF) and eotaxin in interleukin (IL)-13-stimulated RPMI2650 cells...

A group studying acute lung injury observed an increased percentage of neutrophils in the bronchoalveolar lavage (BAL) fluid of mice. BAL was performed, and lung samples were collected sterilely from 5 C57BL/6 mice that had been bred inhouse. Pure colonies of bacteria, initially identified as Bordetella hinzii were cultured from 2 of the 5 mice which had the highest percentages of neutrophils (21% and 26%) in the BAL fluid. Subsequent sequencing of a portion of the ompA gene from this isolate demonstrated 100% homology with the published B...

Primary ciliary dyskinesia (PCD) is a rare genetic disorder caused by structural and/or functional impairment of cilia throughout the whole body. Early diagnosis of PCD is important for the prevention of long‑term sequelae, however early diagnosis is a challenge due to the phenotypic heterogeneity of PCD. In the current study, the patient with PCD was diagnosed at nine years old following several efforts to control intractable airway symptoms. The patient experienced a chronic productive cough beginning in early childhood and had multiple episodes of pneumonia and otitis media with effusion and sinusitis...

RATIONALE: Cystatin A and SPINK5 are endogenous protease inhibitors (EPIs) that may play key roles in epithelial barrier function. OBJECTIVE: The purpose of this study was to investigate the roles of EPIs in the pathogenesis of chronic rhinosinusitis (CRS). METHODS: We examined the expression of cystatin A and SPINK5 in the nasal epithelial cells of patients with CRS. Additionally, the in vitro effects of recombinant EPIs on the secretion of the epithelial-derived cytokines, interleukin (IL)-25, IL-33 and thymic stromal lymphopoietin (TSLP), in airway epithelial cells, and the in vivo effects of recombinant EPIs in the nasal epithelium of mice exposed to multiple airborne allergens (MAA) were examined...
