PURPOSE To measure the optic disc rotation around the vertical and horizontal disc axis and to evaluate associations with general and ocular parameters. DESIGN Population-based study. METHODS In the Beijing Eye Study, 3468 participants (mean age:64.6±9.8 years; range:50-93 years) underwent an ophthalmological examination which included spectral-domain optical coherence tomography (OCT) with...

Nasal bone assessment is an important component in aneuploidy screening first and second trimester. Absence of one nasal carries the same risk for trisomies as absence both bones. Our aim to establish more accurate method detect single also that if length width are up 22 weeks. More than 2000 patients over 2-year period were scanned trimester NT, fetal morphology Doppler parameters. measurement...

PURPOSE To evaluate the thickness and volume of the choroid in healthy Korean children using swept-source optical coherence tomography. METHODS We examined 80 eyes of 40 healthy children and teenagers (<18 years) using swept-source optical coherence tomography with a tunable long-wavelength laser source. A volumetric macular scan protocol using the Early Treatment Diabetic Retinopathy Study g...

BACKGROUND AND OBJECTIVE Supportive care remains the mainstay of therapy in bronchiolitis. Earlier studies suggest that helium-oxygen therapy may be beneficial, but evidence is limited. We aimed to compare efficacy of 2 treatment gases, Heliox and Airox (21% oxygen + 79% helium or nitrogen, respectively), on length of hospital treatment for bronchiolitis. METHODS This was a multicenter random...

Background: Nasal continuous positive airway pressure (NCPAP) is an effective method of ventilation in newborns with respiratory distress syndrome (RDS). Using an appropriate nasal skin care protocol is identical to prevention or reduction of nasal skin breakdown in those who receive NCPAP. This study aimed to investigate the effectiveness of an evidence-based clinical care protocol on nasal sk...

Introduction: There is no single test as a gold standard for the diagnosis of allergic rhinitis (AR). The aim of this study was to assess the usefulness and validity of nasal smear as a quick, easy and inexpensive diagnostic method for diagnosis of allergic rhinitis. Materials and Methods: This study was conducted in a university hospital setting. Nasal smears were taken from 39 patients wit...

PURPOSE To analyze age-related morphological changes of the iridocorneal angle in normal subjects and glaucomatous cases, using anterior segment optical coherence tomography (AS-OCT). METHODS This study involved 58 eyes of 58 open-angle glaucoma cases and 72 eyes of 72 age-matched normal-open-angle control subjects. Iridocorneal angle structures in nasal and temporal regions and anterior cham...

Relative size and arrangement of the brain and paired sense organs are examined in three species of Thorius, a genus of minute, terrestrial salamanders that are among the smallest extant tailed tetrapods. Analogous measurements of representative species of three related genera of larger tropical (Pseudoeurycea, Chiropterotriton) and temperate (Plethodon) salamanders are used to identify changes...

AIM To evaluate the feasibility and diagnostic accuracy of fetal nuchal translucency and nasal bone assessment at 11-14 weeks for screening of trisomy 21 at a single center. METHODS Nuchal translucency measurement and nasal bone evaluation in relation to the fetal karyotype for singleton fetuses were retrospectively assessed at the Ospedale Microcitemico, Cagliari, Italy, in a three-year peri...
