The Individual

Subglottic stenosis is a disorder characterized by narrowing of the airway below the glottis or apposing edges of the true vocal cords. In a broad definition, the term may be used to describe airway compromise in the regions of the larynx or the trachea or both. In children, the stenosis is usually due to scar formation secondary to prolonged airway intubation, rather than to external trauma. The location and extent of the stenosis are highly variable; consequently, corrective measures need to be selected to suit the individual problem. In the present series of children, conservative treatment was adequate for lesser degrees of stenosis; those with more severe scarring required external laryngeal surgery. The preoperative evaluation and treatment plans are reviewed.

Laryngeal Tuberculosis

Some diseases of the larynx that now are rare were common in 1950, when the author began the practice of pediatric otolaryngology. These include laryngeal tuberculosis, bulbar poliomyelitis, and acute exanthemata. The management of laryngotracheitis and supraglottitis has altered markedly, with the mortality reduced drastically. The advent of the operating microscope and carbon dioxide laser has broadened the efficacy of laryngeal surgery. Subglottic stenosis continues to be a challenge despite new operations. Laryngeal transplant may be the answer to some intractable diseases.

The primary concern in laryngeal surgery in the infant and child is to relieve airway obstruction, rather than phonation. Because airway obstruction above the larynx may simulate or be confused with laryngeal pathology, these are described as the signs and symptoms of laryngeal disease. Although tracheotomy in the infant is frequently said to be a cause of a long-term problem, the procedure can be carried out in the smallest premature quite safely and without an extubation problem. The author's method of performing the operation is described. Most laryngeal surgery in the child is performed by the endoscopic approach, special scopes being used for special purposes. In addition to conventional instrumentation the cryoprobe and CO2 laser are employed. The author's method of treating glottic and subglottic stenosis is outlined.

Induced Forgetting

Retrieval-induced forgetting (RIF) refers to the finding that the retrieval of an item from memory impairs the retrieval of related items. The extent to which this impairment is found in laboratory tests varies between individuals, and recent studies have reported an association between individual differences in the strength of the RIF effect and other cognitive and clinical factors. The present study investigated the reliability of these individual differences in the RIF effect. A RIF task was administered to the same individuals on two occasions (sessions T1 and T2), one week apart. For Experiments 1 and 2 the final retrieval test at each session made use of a category-cue procedure, whereas Experiment 3 employed category-plus-letter cues, and Experiment 4 used a recognition test. In Experiment 2 the same test items that were studied, practiced, and tested at T1 were also studied, practiced, and tested at T2, but for the remaining three experiments two different item sets were used at T1 and T2. A significant RIF effect was found in all four experiments. A significant correlation was found between RIF scores at T1 and T2 in Experiment 2, but for the other three experiments the correlations between RIF scores at T1 and T2 failed to reach significance. This study therefore failed to find clear evidence for reliable individual differences in RIF performance, except where the same test materials were used for both test sessions. These findings have important implications for studies involving individual differences in RIF performance.

SummaryPrevious studies on the prevalence of biological abnormalities causing venous thrombosis and the clinical characteristics of thrombotic patients are conflicting. We conducted a prospective study on 2,132 consecutive evaluable patients with venous thromboembolism to determine the prevalence of biological causes. Antithrombin, protein C, protein S, plasminogen and heparin cofactor-II deficiencies, dysfibrinoge-nemia, lupus anticoagulant and antiphospholipid antibodies were investigated. The risk of any of these alterations in patients with familial, recurrent, spontaneous or juvenile venous thrombosis was assessed. The overall prevalence of protein deficiencies was 12.85% (274/2,132) and antiphospholipid antibodies were found in 4.08% (87/2,132). Ten patients (0.47%) had antithrombin deficiency, 68 (3.19%) protein C deficiency, 155 (7.27%) protein S deficiency, 16 (0.75%) plasminogen deficiency, 8 (0.38%) heparin cofactor-II deficiency and 1 had dysfib-rinogenemia. Combined deficiencies were found in 16 cases (0.75%). A protein deficiency was found in 69 of 303 (22.8%) patients with a family history of thrombosis and in 205/1,829 (11.2%) without a history (crude odds ratio 2.34, 95% Cl 1.72-3.17); in 119/665 (17.9%) patients with thrombosis before the age of 45 and in 153/1,425 (10.7%) after the age of 45 (crude odds ratio 1.81, 95% Cl 1.40-2.35); in 103/616 (16.7%) with spontaneous thrombosis and in 171/1,516 (11.3%) with secondary thrombosis (crude odds ratio 1.58, 95% Cl 1.21-2.06); in 68/358 (19.0%) with recurrent thrombosis and in 206/1,774 (11.6%) with a single episode (crude odds ratio 1.78,95% Cl 1.32-2.41). Patients with combined clinical factors had a higher risk of carrying some deficiency. Biological causes of venous thrombosis can be identified in 16.93% of unselected patients. Family history of thrombosis, juvenile, spontaneous and recurrent thrombosis are the main clinical factors which enhance the risk of a deficiency. Laboratory evaluation of thrombotic patients is advisable, especially if some of these clinical factors are present.
