    Notes: We have studied the extent to which learning fibreoptic nasotracheal endoscopy first helped anaesthetists to learn fibreoptic orotracheal endoscopy later, and vice versa. After preliminary training on a bronchial tree model, 30 anaesthetic trainees were randomly allocated to the nasal first/oral second group, who performed 10 nasal intubations followed by 10 oral intubations, or the oral first/nasal second group, who performed 10 oral intubations followed by 10 nasal intubations, in anaesthetised, ASA group I or II patients undergoing elective oral or general surgery. Each type of endoscopy was taught in a standard manner, with the aid of an endoscopic video-camera system, under the supervision of experienced instructors. Performing nasal endoscopy second (average 70.8 s) took significantly less time than performing it first (average 84.4 s) and performing oral endoscopy second (average 35.2 s) took significantly less time than performing it first (average 48.5 s). The mean (SD) total endoscopy time for all the endoscopies (both nasal and oral) in the nasal first/oral second group [1196 (162) s] was not significantly different from that for all the endoscopies in the oral first/nasal second group [1193 (188) s]. Because there is no advantage or disadvantage to be gained in starting to learn either type of endoscopy first, graduated training programmes can be planned according to the availability of suitable patients for fibreoptic intubation, without instructors needing to consider whether trainees make better progress if they learn one technique before the other.

    The laryngeal mask airway as an aid to training in fibreoptic nasotracheal endoscopy (1998)

    Notes: We have investigated the extent to which the laryngeal mask airway, when used as an aid to fibreoptic nasotracheal video-endoscopy training, could reduce endoscopy apnoeic time in anaesthetised, paralysed oral surgery patients. Twenty anaesthetic trainees were randomly allocated to the laryngeal mask airway or control group. Laryngeal mask airway group endoscopies were performed in three stages following insertion of the laryngeal mask airway: stage 1: nasendoscopy, with the lungs ventilated automatically through the laryngeal mask airway; stage 2: removal of the laryngeal mask airway; stage 3: pharyngoscopy, larygoscopy and tracheoscopy. Control group endoscopies were performed conventionally, in one stage. Each trainee performed five nasotracheal intubations. Though total endoscopy time in the laryngeal mask airway group (stage 1 + stage 2 + stage 3 times) was significantly longer (average 136 s vs. 108 s), apnoeic time (stage 2 + stage 3 times) was significantly shorter (average 59 s vs. 108 s) than endoscopy time in the control group. This application of the laryngeal mask airway may have a useful role to play in ensuring patient safety during early fibreoptic training.

    Analysis of differential gene expression supports a role for amyloid precursor protein and a protein kinase C substrate (MARCKS) in long-term memory (2003)

    Notes: Previous work has identified the intermediate and medial part of the hyperstriatum ventrale (IMHV) as a region of the chick brain storing information acquired through the learning process of imprinting. We have examined in this brain region changes in expression of candidate genes involved in memory. Chicks were exposed to a rotating red box and the strength of their preference for it, a measure of learning, determined. Brain samples were removed ≈24 h after training. Candidate genes whose expressions were different in IMHV samples derived from strongly imprinted chicks relative to those from chicks showing little or no learning were identified using subtractive hybridization. The translation products of two candidate genes were investigated further in samples from the left and right IMHV and from two other brain regions not previously implicated in imprinting, the left and right posterior neostriatum. One of the proteins was the amyloid precursor protein (APP), the other was myristoylated alanine rich C kinase substrate (MARCKS). In the left IMHV the levels of the two proteins increased with the strength of learning. The effects in the right IMHV were not significantly different from those in the left. There were no effects of learning in the posterior neostriatum. This is the first study to relate changes in the amounts of MARCKS and APP proteins to the strength of learning in a brain region known to be a memory store and demonstrates that the systematic identification of protein molecules involved in memory formation is possible.

    Learning curves for fibreoptic nasotracheal intubation when using the endoscopic video camera (1997)

    Notes: We have followed the progress of 12 anaesthetic trainees as they learnt how to perform fibreoptic nasotracheal intubation with the aid of an endoscopic video camera system. Each trainee had a structured teaching session on a bronchial tree model, viewed an instructional videotape and then performed 20 nasotracheal intubations on anaesthetised oral surgery patients. Trainees were required to perform the endoscopies under full visual control and to demonstrate airway anatomy as they advanced the fibrescope. They were allowed up to two 2½ min periods to complete nasotracheal endoscopy. All 240 endoscopies were completed within the time limit: 228 were completed within 2½ min and 12 (5%) were completed during the second 2½ min period. We constructed a group learning curve from the pooled data. The half-life of the curve was nine endoscopies. The best fit value for the first endoscopy time was 132 s, and after the 18th (two half-lives) it was 49 s. We analysed the theoretical basis for deriving a learning curve from raw data. This information could form a rational basis for the design of fibreoptic training programmes using video imaging systems.

    Comparison of nacre with other ceramic composites (1990)

    Notes: Abstract Mother-of-pearl, the highly filled ceramic composite of mollusc shell, is compared with other, less highly filled, artificial ceramics. Stiffness is fairly simply related to volume fraction of ceramic, but no model seems to be adequate to describe this relationship. Strength, stress-intensity factor and the work of fracture are also dependent on the ceramic content but in a much more complex manner. Nacre has the highest value for all these parameters.
