INTRODUCTION: Basilar invagination can result from a variety of systemic diseases that can weaken the structural integrity of the craniocervical junction. Definitive treatment often requires ventral decompression along with posterior decompression and fusion. Endonasal odontoidectomy is a relatively new minimal access procedure, however, quality of life after this procedure has not been reported. METHODS: We reviewed a consecutive database of endonasal odontoidectomy patients and identified those having posterior decompression and fusion...

The present study was designed to develop and optimize Temozolomide nano lipid chitosan gel delivery (TMZNLCHG) to target the brain through nasal route. The formulation was developed using chitosan as a gelling agent and Vit E: gelucire 44/14 blend as lipid. The formulations were evaluated for particle size, drug loading, morphology, drug release, nasal diffusion, cell line study, and histopathology study. The average particle size, PDI, %EE, loading, drug release, and % permeation were found to be 134 nm, 0...

PURPOSE: Detection of microaneurysms and/or microhaemorrhages near the fovea when screening for diabetic retinopathy poses a problem because referral to retinal specialists may alarm patients and unnecessarily burden ophthalmologists. METHODS: Six-month prospective study of patients found to have minimal red lesions within one disc diameter of the fovea when screened for diabetic retinopathy. Two 45° digital photographs, one centred on the macula and the other nasal including the optic disc, were taken for each eye...

Chronic rhinosinusitis (CRS) is a common disease of otorhinolaryngology head and neck surgery, manifested as nasal-sinus mucosal chronic inflammation. However, the pathogenesis of CRS is not clear. There are studies found that microRNA (miRNA) involved in CRS gene regulation. In this review, we summarize the expression of miRNAs in CRS, with the in-depth study of the role of miRNAs in CRS, and will further elucidate the pathogenesis of CRS.

Objective: The aim of this study is to discuss the effects and mechanism of salvianolic acid B (SAB) on the proliferation and apoptosis of human nasal polyps fibroblasts (NPFs). Method: The NPFs were treated with SAB at different concentrations (5, 10, 20, 40 μmol/L). CCK-8 assay was used to determine the inhibition of SAB on the proliferation of NPFs and determined the optimum concentration for the following experiments. The NPFs were divided into four groups: a) control group: the cells were cultured in DMEM without TGF-β1 or salvianolic acid B; b) the TGF-β1 group: the cells were cultured in DMEM containing 5 ng/ml TGF-β1; c) the SAB group: the cells were cultured in DMEM containing SAB at the optimum concentration by CCK-8 assay; d) the TGF-β1+SAB treatment groups: the cells were cultured in DMEM containing 5 ng/ml TGF-β1 and SAB at the optimum concentration by CCK-8 assay...

A novel protoparvovirus species, related genetically to human bufaviruses, was identified in dogs with respiratory signs. The canine bufavirus was distantly related to the well-known canine protoparvovirus, canine parvovirus type 2, sharing low amino acid identities in the nonstructural protein 1 (40.6%) and in the capsid protein 1 (33.4%). By screening collections of fecal, nasal, and oropharyngeal samples obtained from juvenile dogs (<1 year of age), canine bufavirus DNA appeared as a common component of canine virome...

Background Saline nasal lavage is one of the treatments of sinonasal diseases. Evidence from basic research favors hypertonic saline (HS) over isotonic saline (IS) for mucociliary clearance, but evidence from clinical studies is controversial. Conversely, HS may carry greater side effects. Objective To compare the effects of HS and IS nasal irrigation in treating sinonasal diseases. Methods Systematic search with Ovid MEDLINE, Scopus, PubMed, Google Scholar, and Manual additional sources was conducted. Randomized controlled trials comparing HS with IS nasal irrigation in treating any sinonasal diseases, including rhinitis and rhinosinusitis, were included...

BACKGROUND: Mohs micrographic surgery (MMS) is used to treat cutaneous malignancies in locations to maximize tissue sparing. The authors' aim is to demonstrate the utility of conservative thickness layers (CTL) in MMS and review patient and tumor characteristics and the potential anatomic locations where this technique may be most useful. METHODS: We performed a retrospective chart review of patients with tumors treated with CTL in MMS of 339 tumors, recording patient demographics, tumor characteristics, MMS stages for clearance, repairs, complications, and follow-up...

PURPOSE: To correlate the pathologic features and heat shock protein 47 (HSP47) expression in the nasal mucosa and lacrimal sac with the surgical outcomes of endoscopic endonasal dacryocystorhinostomy (EDCR). METHODS: Specimens of the nasal mucosa and lacrimal sac over the rhinostomy site were collected during the operation. Haematoxylin-eosin and immunohistochemical staining were performed to determine the pathologic features (inflammation, fibrosis, squamous metaplasia) and the expression of HSP47 in the epithelium and sub-epithelial glands of the nasal mucosa and lacrimal sac...

Mucormycosis is a rare clinical entity, often affect immunocompromised patients. It is an emergency situation and has poor prognosis. Prompt diagnosis with tissue biopsy, local control of the disease by aggressive surgical debridement and appropriate systemic antifungal treatment improve the prognosis and survival of the patients. Treatment of mucormycosis needs antifungal agents such as Amphotericin B and wide surgical debridement. Early diagnosis and treatment is often needed for survival of the patients...

BACKGROUND: High-flow nasal cannula oxygen therapy (HFNC) is widely used mainly in the acute care setting, but limited data are available on real-world practice in adults. The objective of this study was to describe HFNC practices in Japanese adults. METHODS: A retrospective cross-sectional multicenter survey of adult patients receiving HFNC from January through March 2015 was conducted in 33 participating hospitals in Japan. RESULTS: We obtained information on 321 patients (median age, 76; 218 men, 103 women; median estimated PaO2 /FI O2, 178 mm Hg) from 22 hospitals...
