Purpose To evaluate whether corneal confocal microscopy (CCM) detects axonal degeneration and whether this is associated with retinal nerve fiber degeneration and clinical disability in patients with multiple sclerosis (MS). Methods Twenty-five patients with MS and 25 healthy control subjects underwent CCM, optical coherence tomography (OCT), and assessment of neurological disability using th...

BACKGROUND Microbes and allergens can stimulate the nasal mucosa, potentially leading to the development of acute bacterial rhinosinusitis (ABRS). This study was designed to determine if allergen exposure alters the sinonasal microbiome. METHODS We performed a parallel observational study of healthy adults with seasonal allergic rhinitis (SAR; grass or tree, n = 20) or nonallergic subjects (n...

INTRODUCTION Malignant melanoma rarely develops in the mucous membranes. Statistical data indicate that rhinosinusal mucosal melanoma was reported in less than 1% of all melanic tumors and in 2-8% of all cancers developed in the nasal fossae and sinuses. Due to reduce and non-specific symptoms and a high degree of invasion away, patients come for a medical expertise in advanced stages of the di...

PURPOSE To report and analyze factors influencing topographical and interocular variations in choroidal thickness (CT) in a healthy adult population. METHODS One hundred eyes of 50 healthy subjects underwent visual acuity and axial length measurements and optical coherence tomography (OCT) with enhanced depth imaging (EDI). CTs at the fovea and at 3 mm nasal, temporal, superior, and inferior ...

BACKGROUND: Though the development and fitting of scleral contact lenses are expanding steadily, there is no simple method to provide scleral metrics for scleral contact lens fitting yet. The aim of this study was to establish formulae for estimation of the axial radius of curvature (ARC) of the anterior sclera using ocular biometric parameters that can be easily obtained with conventional de...

background the efficiency of nasal surgeries can be determined by objective or subjective methods. we have assessed the effect of nasal obstruction after different nasal surgeries using acoustic rhinometry (ar) and nasal obstruction symptom evaluation (nose) scale. methods between may 2011 and may 2012, 40 young adult patients and 10 healthy volunteers as control group who referred to otorhinol...

Nasal continuous positive airway pressure (nCPAP) in premature babies may rarely lead to necrosis of the columella. Subsequent functional and cosmetic impairments require surgical corrections to restore nasal anatomy and architecture. The objective of this report is to document the technique of reconstruction in a baby with columella necrosis due to nCPAP treatment. A 21-month-old baby was refe...

introduction: nose morphology depends on gender, ethnicity, and environmental conditions. it can be used in identification of the race and sex of persons whose identity is unknown. nasal index is a useful tool in anthropometry. methods: in this study, nasal parameters of iranian males and females students were measured (nasal height, nasal width, and nasal index). this study was conducted on 20...

This study investigates nasal murmur in preconsonantal environments across Portuguese varieties from Africa, Asia, Europe and South America. We analyzed cross-syllable tokens of the type nasal vowel (Vn) + stop (Cs) or fricative (Cf) to: compare the presence or absence of nasal murmur (N) across pan Lusophone varieties, and examine the acoustic length of N, alone and as a proportion of the tota...

We experienced a very rare case of maxillary bone metastasis from lung cancer. The patient was a 77-year-old Japanese man with 1-month history of right alar swelling with hard pain as his chief complaint. Computed tomography scan showed a 1 cm length round lesion in the right nasal vestibule close to the pyriform fossa edge of the right maxillary bone. He had severe pulmonary dysfunction due to...
