Approach Data were gathered during direct observation of consultations at eight practices. Clinical examinations were categorised as full, focused or ‘none’. Abnormalities detected by the veterinarian on clinical examination were also recorded, as was whether the patient was weighed. Data were also gathered on patient signalment, type of consultation and the number of problems discussed per pat...

Observers often fail to detect the appearance of an unexpected visual object ("inattentional blindness"). Experiment 1 studied the effects of fixation position and spatial attention on inattentional blindness. Eye movements were measured. We found strong inattentional blindness to the unexpected stimulus even when it was fixated and appeared in one of the expected positions. The results suggest...

We evaluated the feasibility and costs of utilising hand-held cardiac ultrasound (HHCU) as part of a community-based pre-participation cardiovascular screening programme. Ninety-seven school children were screened using a personal history, a physical examination, a resting 12-lead electrocardiogram (ECG) and a HHCU. A consultant cardiologist independently reviewed and reported the data. Previou...

An experiment examined visual performance in a simulated luggage-screening task. Observers participated in five sessions of a task requiring them to search for knives hidden in x-ray images of cluttered bags. Sensitivity and response times improved reliably as a result of practice. Eye movement data revealed that sensitivity increases were produced entirely by changes in observers' ability to r...

The experiments reported here provide an insight into how the use of working memory is influenced when eye movements become ‘costlier’ in a visual task. In our comparative search paradigm, each half of the screen contains a column of simple geometrical objects of three sizes and forms. Participants have to detect whether the two halves of the screen are exactly identical or contain a difference...

There is an emerging literature on visual search in natural tasks suggesting that task-relevant goals account for a remarkably high proportion of saccades, including anticipatory eye movements. Moreover, factors such as "visual saliency" that otherwise affect fixations become less important when they are bound to objects that are not relevant to the task at hand. We briefly review this literatu...

Recent reports from the American Heart Association (AHA) and by lead authors of the 2014 AHA guidelines for cardiovascular screening in athletes present many inconsistencies that need to be critically examined. In three different AHA statements (1996, 2007, 2014), the AHA has endorsed cardiovascular screening: “Both AHA and ESC consensus panels have agreed previously that screening to detect ca...

Trisomy 8 mosaicism syndrome (T8MS ) is a rare chromosome disorder caused by the presence of extra in some cells body. T8MS clinically variable condition associated with number developmental abnormalities. We report dysmorphic features and congenital anomalies. A 3.5-month-old boy was referred to genetic department because his atypical facial appearance. Physical examination revealed microcepha...

tooth fusion is a developmental anomaly characterized by the :union: between the dentin and/or enamel of at least two separately developing teeth. the fusion of posterior teeth is an uncommon occurrence. in this article, we report a rare case of unilateral fusion of a mandibular second molar with a paramolar. carious exposure mandated endodontic treatment. the unusual morphology and complex roo...

trauma to primary teeth can lead to devastating sequels in development of permanent successors. the disturbance may range from enamel hypoplasia and/or hypo-calcification to arrest of dental bud development. crown dilaceration of permanent teeth is one of the consequences of trauma to deciduous teeth mainly due to intrusion or avulsion. this report presents a mandibular central incisor with dil...
