Developing ‘FOCUS’: A project to promote effective practice in child and adolescent mental health services in the UK

Summary UK health policy requires child and adolescent mental health service providers to demonstrate that their services are effective. The FOCUS project has been developed to improve the availability and accessibility of research evidence and innovation, to support purchasers in the effective commissioning of services and to help providers base service provision on evidence of effectiveness and develop methods of evaluation.

Evaluation by dental students of a communication skills course using professional role-players in a UK school of dentistry

This paper reports student (n = 180) feedback on the role-play teaching methodology used in behavioural sciences teaching at The School of Dentistry in Birmingham (UK). The feedback received on this well-established (since 1995) educational programme was collected via questionnaire (100% response rate), requiring Likert scale and free text responses. Generally students reported that they had enjoyed and valued the session. Over two-thirds (69.7%) of students rated the role-players as 'very real' and over three-quarters (78.9%) rated their feedback as 'very fair'. The data collected from this study will inform future curriculum development. Student feedback was very positive and demonstrated that the cohort (86% of all students studying in years 1, 2 and 3) found the use of professional role-players involved in behavioural sciences teaching to be both acceptable and valuable.     

Developing a Peer Review Process for Web-based Curricula

The World Wide Web creates new challenges and opportunities for medical educators. Prominent among these are the lack of consistent standards by which to evaluate web-based educational tools. We present the instrument that was used to review web-based innovations in medical education submissions to the 2003 Society of General Internal Medicine (SGIM) national meeting, and discuss the process used by the SGIM web-based clinical curriculum interest group to develop the instrument. The 5 highest-ranked submissions are summarized with commentary from the reviewers.

Clinical and Physical Evaluation of the Infertile Male: Testicular Measurement or Orchidometry/Klinische und physikalische Bewertung des infertilen Mannes: Hodenmessung oder Orchidometrie

Summary: For the quantitative determination of the testicular size or volume, two groups of apparatus are available: on the one hand, model testes, which are extremely valuable in longitudinal and cross-sectional studies during the period of pubescence, and on the other hand, measuring devices, with which the testicular dimensions can be specified. The latter instruments are helpful chiefly during the adolescent years and the diagnosis of problems surrounding fertility. The testicular volume can be calculated subsequently from the specific testicular measurements. The formula, for computing the volume of an ellipsoid, seems to be the most suitable for this purpose. Appliances also have been developed, which allow the largest (longitudinal) dimension (in mm) and the testicular volume (in cm3) to be read off simultaneously. A tonometer can be useful to quantitatively estimate the testicular consistency, which is a parameter of the testicular integrity at the level of tubular function (spermatozoa production).     

Zero-Order Release Formulation of Oxprenolol Hydrochloride with Swelling and Erosion Control

Zero-order release of oxprenolol hydrochloride was obtained by controlling the swelling and erosion of the matrix. This formulation involves only mixing of drug, hydroxypropylmethylcellulose (HPMC), and sodium carboxymethylcellulose (Na CMC) at the ratio of 1:0.4:1.6, respectively, and compressing the mixture directly into tablets. The in vitro release pattern from this optimized matrix tablet was reproducible. Accelerated stability studies revealed that the optimized formulation remains stable for an approximately 2-year shelf life. This sustained-release (SR) tablet was evaluated in dogs, and for comparison a conventional (CV) formulation was also given at the same dose level. Plasma oxprenolol levels were monitored by a sensitive and specific high-performance liquid chromatographic (HPLC) method. Significant differences in the pharmacokinetic parameters, i.e., lower C _max, higher values of t _max, MRT, AUC, and plasma concentration at 24 hr, and nearly constant plasma levels over 12 hr, indicated that the SR matrix tablet is superior to the CV rapid-releasing formulation. The in vitro release parameters and in vivo pharmacokinetics correlated well.
