We have used immunohistochemical staining to assess the expression of cyclin D I in formalin-fixed sections of 345 breast carcinomas, dating back 20 years. Clinical follow-up data were available on all patients. Approximately 50% of the tumours showed excessive nuclear staining for cyclin DI as compared with normal epithelium. Some tumours showed strong cytoplas-mic staining in the absence of nuclear staining, and around 25% of the tumours were judged to be negative for nuclear cyclin D I. Contrary to expectations, moderate/strong staining for cyclin D I was associated with improved relapse-free and overall survival relative to patients whose tumours stained weakly or negatively. Conversely, tumours that were considered negative for cyclin DI staining had an adverse prognosis, and the poor outcome was further accentuated if the tumours were also oestrogen receptor-negative. A possible explanation for our findings is that tumours in which cyclin D I levels are abnormally low may have sustained mutations in other genes, such as R 6 I and that it is this abnormality that has the more significant impact on survival from breast cancer. 8 1996 Wiley-Liss, Inc.

Very few studies have addressed the question of adherence of haemophiliacs to their treatment. The aim of our study was to compare their levels of adherence to therapy and also to provide recommendations. Professionals of an international research company performed individual interviews with 30 patients in each of six European countries (France, Germany, Italy, Spain, Sweden and UK) resulting in a total of 180 patients. Twenty-eight interviews with haemophilia physicians and specialist nurses were also undertaken. Overall adherence to treatment was high (80-87% in each country). There was a positive correlation between greater adherence and younger age, prophylactic treatment, time spent with a haemophilia treatment centre (HTC) and the quality of the relationship with the haematologist and nurse. The four leading reasons for not using the prescribed amount of clotting factor or skipping the administration interval were reduction, fluctuation or disappearance of symptoms, forgetfulness, lack of time for treatment and convenience. These reasons differed according to the country and the age of the patient. The main suggestions made by patients to improve adherence related to HTC, environment and factor concentrates. Patients considered also that internet and electronic patient diaries were likely to improve adherence. In this selected group of European haemophilia patients, adherence to treatment appears higher than for most patients with other chronic diseases. However, it remains important to be aware of the possibility of non-adherence given the serious implications, particularly when considering a differently selected group of patients.

Summary.  Although most surgical and invasive procedures can be performed safely in patients with haemophilia, the optimal level and duration of replacement therapy required to prevent bleeding complications have not been established conclusively. For providing more insight into optimal therapy during invasive procedures, a literature review of surgical procedures in patients with haemophilia was conducted. Concomitantly, current practice was surveyed in 26 European Haemophilia Comprehensive Care Centres, representing 15 different countries. The review identified 110 original papers published between 1965 and 2007. Of these, only two studies were randomized controlled trials. Target levels and the duration of replacement therapy in the published studies were as follows. For major orthopaedic surgery: preoperative targets were 80–90%; postoperative targets showed a high degree of variation, with trough levels ranging from 20% to 80%, duration 10–14 days; for liver biopsy, 70–100%, 1–7 days; tonsillectomy: 90–100%, 5–11 days; indwelling venous access device insertion: 100%, 3–10 days; circumcision: 50–60%, 2–4 days; dental surgery: 30–50%, single treatment. With the exception of dental surgery, current practice in Europe, as assessed by the survey, was largely in agreement with published data. In conclusion, this study provides both a comprehensive review and a large survey of replacement therapy in patients with haemophilia undergoing invasive procedures; these data have informed the consensus practical treatment recommendations made in this paper. This study highlights the need for better‐designed studies in order to better define minimal haemostatic levels of replacement therapy and optimal treatment duration.

The Framing Camera (FC) is the German contribution to the Dawn mission. The camera will map 4 Vesta and 1 Ceres through a clear filter and 7 band-pass filters covering the wavelengths from the visible to the near-IR. The camera will allow the determination of the physical parameters of the asteroids, the reconstruction of their global shape as well as local topography and surface geomorphology, and provide information on composition via surface reflectance characteristics. The camera will also serve for orbit navigation. The resolution of the Framing Camera will be up to 12 m per pixel in low altitude mapping orbit at Vesta (62 m per pixel at Ceres), at an angular resolution of 93.7 μrad px −1 .The instrument uses a reclosable front door to protect the optical system and a filterwheel mechanism to select the band-pass for observation. The detector data is read out and processed by a data processing unit. A power converter unit supplies all required power rails for operation and thermal maintenance. For redundancy reasons, two identical cameras were provided, both located side by side on the +Z-deck of the spacecraft. Each camera has a mass of 5.5 kg.

Summary. Recent reports have suggested that the incidence of inhibitors in haemophilia is the highest in those first exposed to factor VIII under 6 months of age. In this study, we investigated inhibitor development in children first exposed to FVIII as neonates and also examined the effect of other genetic and environmental variables. Three hundred and forty-eight children with severe haemophilia A were investigated. Inhibitors developed in 68 of 348 (20%), with 34 of 348 (10%) high titre inhibitors. The incidence in relation to initial FVIII exposure was: <1 month nine of 35 (26%), 1-6 months 13 of 51 (25%), 6-12 months 27 of 130 (21%), 12-18 months 13 of 66 (20%) and >18 months six of 66 (9%). While we observed a significant difference in inhibitor development and age at first exposure across all age groups (P ¼ 0.018), no significant difference was observed in children treated at different time points during the first year of life (P ¼ 0.44). Similar results were obtained for high titre inhibitors. There was also no difference in the incidence of inhibitors in relation to initial FVIII exposure in a subgroup of 144 children with the intron 22 mutation. Inhibitors developed more frequently in those initially treated with recombinant when compared with plasma-derived FVIII (P ¼ 0.006) and in those with a major molecular defect (P ¼ 0.009). In this study, exposure to FVIII during the neonatal period was not associated with a higher incidence of inhibitors than those treated later during the first year of life. Initial treatment with recombinant FVIII and the presence of a major molecular defect were the most important variables affecting inhibitor development.
