BACKGROUND: Ireland has been relatively free of sickle-cell disease (SCD) and a care policy for the disease has not been established. AIM: To determine the prevalence of childhood SCD in Ireland and to predict requirements for a comprehensive care and assessment programme. METHODS: We retrospectively analysed the data of children with SCD presenting with sickle-cell crisis to one institution from January 1999 to April 2001. We also determined the nature and severity of the presenting haemoglobinopathy phenotype. RESULTS: Ninety-two patients with haemoglobinopathy have been registered with the Paediatric Haematology Service. The majority are from Nigeria with a smaller number from Angola and the Congo. Sixty have sickle-cell trait, 23 SCD, four haemoglobin SC disease and two haemoglobin E (HbE). There have been 32 sickle-cell crises. The majority were haemolytic or splenic sequestration events with a smaller number of aplastic and vaso-occlusive events and one osteomyelitis. CONCLUSION: The increasing number of children presenting with SCD as a result of the increasing refugee numbers requires a comprehensive care approach similar to that required for paediatric haemophilia to ensure optimum care.

Conversion of 17 alpha-hydroxyprogesterone to 5 alpha, 3 alpha, and 20 alpha-reduced metabolites by female rat anterior pituitary and hypothalamus.

The metabolism of 17 alpha-[3H]hydroxyprogesterone was examined in female rat anterior pituitary and hypothalamic tissues. After reverse isotopic dilution analysis and purification to constant specific activity, the following 5 alpha-, 3 alpha- and 20 alpha-reduced products were detected in both tissues: 17 alpha-hydroxy-5 alpha-pregnane-3,20-dione; 3 alpha,17 alpha-dihydroxy-5 alpha-pregnan-20-one; 17 alpha,20 alpha-dihydroxy-4-pregnen-3-one and 5 alpha-pregnane-3 alpha,17 alpha,20 alpha-triol. While the metabolites formed were qualitatively the same, there were quantitative differences between the two tissues. The 3 alpha,5 alpha-reduced metabolite, 3 alpha,17 alpha-dihydroxy-5 alpha-pregnan-20-one, was the principal product in the anterior pituitary while the 5 alpha-reduced metabolite, 17 alpha-hydroxy-5 alpha-pregnane-3,20-dione, was produced in largest amount by the hypothalamus. With both tissues, the aforementioned four products plus starting substrate accounted for nearly all of the starting radioactivity. There was no evidence for the formation of C19 steroids (androgens) despite the presence of the 17 alpha-hydroxy group.

Towards a strategy for teaching information skills to student nurses.

It is being increasingly recognised that nursing needs to be constructively and critically informed by a body of scientific knowledge, and that practitioners need to develop active and independent learning styles which enable them to access, use and evaluate such knowledge. This approach has led to many teachers reexamining their approaches to teaching and learning, with an increasing emphasis upon cultivating lifelong learning and in providing students with the skills to facilitate this process. It is against this backdrop that the authors developed a comprehensive information skills package for student nurses undertaking an ENB Diploma in Nursing Science/Registered General Nurse Course (ENB Pilot Scheme Course). The package was designed specifically for use within the Newcastle Polytechnic Library though with modifications, it could be used in other venues. This paper explores the rationale and structure of the package and its subsequent implementation and evaluation.
