The article presents information on the scheme known as "The Pimlico Connection" and highlights factors which seem important in making this work. Under the scheme undergraduate students from the Imperial College of Science and Technology in London, England, give tuition to pupils in three Inner London comprehensive schools. Such a procedure is fertile in possibilities for students to enrich their own education by teaching people younger than themselves. Tutoring has been revived in recent years to meet situations of acute need and as a method of enriching the education of people who take part either as tutors or tutored. Tutoring is based on two theoretical propositions. The first is the Role Theory, according to which children will learn more effectively from people near their own age than from teachers who are older and different in general outlook and culture. The other is the Learning Theory, which suggests that young people will learn more effectively with the individual attention that tutoring can provide than in classes with one teacher to up to thirty pupils.

Summary: The relationship between changes in hospital service interventions at St Mary's Hospital, London, reduced case fatality for patients with their first episode of Pneumocystis carinii pneumonia (PCP) and improved survival from diagnosis of AIDS was investigated for the period 1982-1991. Multivariate logistic regression models identified factors independently associated with episode survival; for those patients who survived their first episode of PCP, survival from time of diagnosis of AIDS was analysed using multivariate Cox's proportional hazards models. The case-fatality rate after 1987 was significantly lower for the 159 subjects. Median survival from diagnosis of AIDS increased significantly from 142 days to 554 days ( P =0.01). Improved survival of first episode of PCP was associated with it being the index diagnosis and having a haemoglobin at diagnosis of PCP greater than 12 g/dl. The presence of a concurrent AIDS-defining condition in patients who presented with an A-a gradient equal to or greater than 40 mmHg was associated with reduced episode survival, especially before 1987. For the 126 individuals who survived their first episode of PCP, death rates were lowest in patients treated with primary or secondary PCP prophylaxis and those who received zidovudine since their first episode of PCP. Survival in patients with HIV disease is better in patients who receive appropriate antiretroviral treatment of HIV infection and timely treatment of opportunistic illnesses. Early diagnosis of HIV-1 infection with early diagnosis and treatment of first episode of PCP was associated with improved episode survival. Subsequent medical follow up combined with PCP prophylaxis and zidovudine were significantly associated with long-term survival. [ABSTRACT FROM AUTHOR]
