The laryngeal mask airway (LMA) has become a popular alternative to endotracheal intubation. We report a case in which appropriate LMA placement resulted in an unrecognized neck mass and subsequent erroneous diagnosis of cervical lymphadenopathy. Otolaryngologists should be aware that the LMA may result in alterations of neck anatomy.
The American Academy of Pediatrics proposes the following guidelines for the pediatric perioperative anesthesia environment. Essential components are identified that make the perioperative environment satisfactory for the anesthesia care of infants and children. Such an environment promotes the safety and wellbeing of infants and children by reducing the risk for adverse events.
The purpose of this study was to determine the effect of lengthening the anesthesia residency by the American Board of Anesthesiology on the education of anesthesia subspecialists. A survey of anesthesia residency programs was conducted from 1987 to 1991. The most frequent subspecialty practice in the clinical anesthesia (CA) 3 year is cardiovascular anesthesia. However, the percentage of CA3 residents spending extended time (greater than or equal to 6 months) in subspecialty education has significantly decreased. For example, the percentage of CA3 residents spending 12 months in subspecialty education has decreased 83%. There appears to be a slight increase in the number of CA4 or PGY5 residents (fellows) electing subspecialty practice. It is concluded that the 3-year curriculum has produced a negative impact on the education of anesthesia subspecialists.

Membranous laryngotracheobronchitis (membranous croup), not previously described as a distinct entity, is characterized by diffuse inflammation of the larynx, trachea, and bronchi with adherent or semiadherent mucopurulent membranes in the subglottic trachea (conus elasticus) and in the upper trachea distal to the conus elasticus. We reviewed 28 cases of membranous croup diagnosed by endoscopy and/or radiographic examination. The importance of the recognition of membranous croup as a distinct entity is discussed. The characteristic radiologic findings consist of subglottic tracheal narrowing, irregularity of contour of the proximal tracheal mucosa, and sometimes detached or partially detached proximal tracheal membranes, which can be mistaken for tracheal foreign bodies.
