Towards inclusion? Models of behaviour support in secondary schools in one education authority in Scotland
No full textThis article draws on data emerging from an evaluation of behaviour support strategies in secondary schools in an education authority in Scotland. The authors all work at the University of Glasgow. Jean Kane has research and teaching interests in the area of special educational needs; she offers consultancy to local authorities in the development of inclusive policies and practices in schools. Dr George Head has research and teaching interests in the area of social, emotional and behavioural difficulties and social inclusion; he is also an experienced teacher. Both Jean Kane and George Head are lecturers in the Faculty of Education. Nicola Cogan is a researcher at the Strathclyde Centre for Disability Research and has a background as a research psychologist in the health sector.
In Scotland, the growth of behaviour support provision is closely related to broader policy on social inclusion. It is argued in this article that new models of behaviour support can be developed in the light of previous and related experience in the development of inclusive support systems in schools. The authors present a typology of behaviour support, drawing upon their evaluation of provision, and discuss the characteristics of the types of support that emerge. Using data from exclusion statistics, pupil case studies and interviews with teachers, managers, pupils and parents, Jean Kane, George Head and Nicola Cogan explore the implications of their work for future developments in support for pupils who present difficult behaviours
Thioridazine Retinopathy
No full textPresenting Symptom: Blurred vision OU. Pathology: Mottled retinal pigment. Clinical: The patient was a 30-year old female who complained of blurred vision after receiving 2800 mg of thioridazine daily for 15 days. The fundi showed a diffuse mottled pigmentation that was most marked in the central area. (Case reported by Hagopian, V. et al, Amer J Psych 123: 97-100, 1966.)

Cogan Lid Twitch
No full textA 50-year-old woman presented with ptosis of her left eyelid for 6 months. Several exam findings including variable and fatigable ptosis, and Cogan lid twitch, raised suspicion for Myasthenia Gravis. Acetylcholine receptor binding, blocking, and modulating antibodies were negative, and single fiber EMG was normal. MRI brain/orbits without and with contrast was unremarkable. There was no evidence of thymoma on chest CT. Diagnosis of Myasthenia was ultimately confirmed with positive ice pack test, positive edrophonium (Tensilon) test, and suggestive history and exam findings. The patient was started on Pyridostigmine 60mg 5 times daily, to which she responded well, but stopped it a year later on her own with resolution of diplopia and ptosis. The video displays a Cogan lid twitch of the patient\u27s left eyelid. First described by Dr. David G. Cogan in 1965, the Cogan lid twitch (CLT) is a sign of Myasthenia Gravis and can be elicited by having the patient initially maintain downward gaze and then look up to the primary position. The lid will show a brief upward twitch. Cogan theorized that this sign could be explained by the quick fatigability and rapid recovery of the myasthenic levator palpebrae superioris. The downward gaze allows for relaxation of the muscle which allows for recovery once the patient looks straight ahead. As the elevation is only maintained for a brief period, it appears as a twitch [1]. The specificity of the CLT has been reported as 99% and sensitivity as 75% in one study [2]. [1] Cogan DG.
