The abundant glands situated in the lamina propria of the human anterior middle nasal turbinate were complex tubules that consist of serous, seromucous, and mucous cells, either singly or in combination. Serous granules were homogeneously dense, but could have a small lighter core. Seromucous granules had a dense rim and a large compartment of appreciably lighter density. Gradation between serous and seromucous granules made precise identification of these secretory cell types difficult. Mucous cells were of conventional morphology. The secretory tubules, which possessed a complement of myoepithelial cells, gradually transformed into ducts or the changeover was relatively sudden. The ductular portions of the tubules consisted either of tall prismatic cells or of shorter columnar cells, both of which lacked secretory granules, but had many mitochondria in their supranuclear cytoplasm. In many cases the ducts, for most of their length, consisted of secretory cells. These glands clearly participate in the elaboration of the glycoconjugate coat that serves to protect the nasal mucosa and keeps it from drying out

On the basis of the good predictions for phonemes correct, we conclude that closed-set feature identification may successfully predict phoneme identification in an open-set word recognition task. For word recognition, however, the PCM model underpredicted observed performance, and the addition of a mental lexicon (ie, the SPAMR model) was needed for a good match to data averaged across 7 adults with CIs. The predictions for words correct improved with the addition of a lexicon, providing support for the hypothesis that lexical information is used in open-set spoken word recognition by CI users. The perception of words more complex than CNCs is also likely to require lexical knowledge (Frisch et al, this supplement, pp 60-62) In the future, we will use the performance off individual CI users on psychophysical tasks to generate predicted vowel and consonant confusion matrices to be used to predict open-set spoken word recognition. $$:

OBJECTIVE: To measure the impact of tonsillectomy and adenoidectomy (T&A) on children's behavioral and emotional problems using a standardized assessment. DESIGN: Prospective study. SETTING: Tertiary care children's hospital. PATIENTS: Thirty-six children, aged 2 through 18 years, with symptoms of nighttime snoring, observed apneas, and daytime mouth breathing and physical examination results demonstrating 3+ or 4+ tonsils scheduled for T&A. INTERVENTION: Parents completed a standard survey of their children's symptoms of sleep apnea and a standardized measure of children's competencies and problems, the Child Behavior Checklist for ages 2 through 3 years or 4 through 18 years, before T&A and 3 months postoperatively. MAIN OUTCOME MEASURE: The Child Behavior Checklist total problem score. RESULTS: The preoperative Child Behavior Checklist total problem score was consistent with abnormal behavior for 10 children (28%). After T&A (n = 15), only 2 scores were abnormal, but the change was not statistically significant. In contrast, the mean total problem score was 7.5 points lower after surgery (95% confidence interval, 5.1-9.7), indicating a significant decrease (P<.001, matched t test). CONCLUSIONS: This pilot study demonstrates a high prevalence (28%) of abnormal behavior in children undergoing T&A for chronic upper airway obstruction. Scores on a standardized measure of behavior improve following T&A, but larger studies with increased statistical power are needed to clarify the degree of improvement and its clinical importance

Although laryngotracheoesophageal clefts are often found in association with other well-described anomalies, we know of no previous reported association with eosinophilic gastroenteritis, a disorder of unknown etiology characterized by eosinophilic infiltration of the gastrointestinal tract. We treated 2 children who had laryngeal clefts and eosinophilic gastroenteritis. Since the esophageal inflammatory changes found in eosinophilic gastroenteritis may persist despite aggressive therapy, management of the laryngotracheoesophageal clefts is more complicated. The diagnosis of eosinophilic gastroenteritis should not be overlooked in patients with laryngotracheoesophageal clefts and warrants prompt referral to a pediatric gastroenterologist
