Disease relevance of Glottis

 

High impact information on Glottis

  • We calculated Qaw using the time-dependent decrease in DME concentration in relation to the helium concentration in an expired volume fraction between 80 and 130 ml (representing an anatomic dead-space segment distal to the glottis) and the mean DME concentration [3].
  • A fiberoptic bronchoscope positioned in the airway photographed the glottis before induction of anesthesia A second photograph was obtained after induction with 3 microg/kg sufentanil administered during a period of 2 min [4].
  • The endocrine cells, which were immunoreactive for protein gene product 9.5 (PGP 9.5) and calcitonin gene-related peptide (CGRP), were observed within the epithelial layer of the laryngeal cavity and in the laryngeal gland, while solitary endocrine cells with apical and/or basal cytoplasmic processes appeared near the glottis [5].
  • The structure of the nervous network and the distribution of tyrosine hydroxylase (TH)- and various neuropeptide-containing nerves were immunohistochemically studied in the glottis of the dog [6].
  • In the subepithelial layer of the posterior glottis, a moderate number of galanin (GAL)-immunoreactive nerve fibers were observed, while only a few fibers were present in the anterior glottis [6].
 

Biological context of Glottis

 

Anatomical context of Glottis

  • It is concluded that the site of the cause of inability to maintain bag-and-mask ventilation after fentanyl lies above the trachea, specifically at the glottis [8].
  • We advanced a 3.1-mm pediatric fibreoptic bronchoscope (FOB) through an orally inserted nasopharyngeal airway to identify the glottis and sprayed 0.5% lidocaine onto the airway mucosa [9].
 

Associations of Glottis with chemical compounds

  • Adding CO2 to the inspired gas led to partial widening of the glottis in two of three subjects [10].
  • Benzocaine-based anesthetic sprays are commonly used in sheep to anesthetize the nasal passages and glottis before intubation [11].
  • Thus, as in the diaphragm and thyroarytenoideus muscles, onset time and duration of succinylcholine or vecuronium blockade were shorter in the abductor muscle of the glottis, cricoarytenoideus dorsalis, than in the limb muscle [12].
  • Any movement of the injected O2 to the alveoli through an open glottis probably resulted from simple diffusion as well as from agitation and mixing of gases by simulated respiratory activity [13].
  • Both inspiratory and expiratory glottis width decreased after histamine had been inhaled (dose range 2.4-9.6 mg) or injected intravenously (dose of 4 micrograms/kg), being associated with a reduction in forced expired volume in 1.0 s [14].
 

Gene context of Glottis

  • Twenty-five patients with severe squamous intraepithelial neoplasia, grade 3 (SIN III) of the glottis were identified and followed up; three patients (12%) eventually developed invasive carcinoma and nine patients (36%) were noted to have coexisting microinvasive carcinoma [15].
  • The integrated peak V activity (I-ENGv) showed a linear relationship to OBP (r = 0.944) in the glottis occluded frog, but a curvilinear relationship to peak buccal pressure (peak BP) in the spontaneously breathing frog during inflation period [16].
  • The regurgitation of a bolus started with a contraction of cranial compartment 1 (C 1) during a B-sequence, followed by a deep inspiration with closed glottis [17].
  • In a patient with the Treacher-Collins syndrome in whom conventional laryngoscopy had proved impossible and tracheal intubation extremely difficult, this manoeuvre exposed the entire glottis and made tracheal intubation under direct vision easy [18].
  • In all T2 cancers of the glottis and subglottis (n = 36), a total resection was possible [19].
