    Notes: Over 50 unselected women with maternal venous thromboembolism were screened for the prothrombin 20210 G→A and MTHFR C677T mutations, in addition to screening for other thrombophilias. The prevalence of thrombophilia in these women was compared with its prevalence in the general population in our area. The prothrombin (OR 4.4; 95% CI 1.2-16) and factor V Leiden (OR 4.5; 95% CI 2.1-14.5) mutations were more common in our patients, compared with the general population, whereas women homozygous for the C677T mutation in the methylene tetrahydrofolate reductase gene (OR 0.45; 95% CI 0.13-1.58) were not. It is recommended that women with a personal or strong family history of venous thromboembolism should be screened for the prothrombin mutation either before or early in pregnancy, in addition to screening for other thrombophilias. Screening for the MTHFR mutation does not appear to identify women at increased risk of maternal venous thrombosis.

    Notes: Acquired inhibitors to factor VIII (FVIII) are rare, but life-threatening in up to 22% of cases. The optimal therapy for suppression of these inhibitors remains unclear. Prednisolone is the mainstay of therapy, producing responses in approximately 30% of cases. Intravenous immunoglobulin (IVIg) has a similar response rate, but a more rapid effect. We report the results of prednisolone 1 mg kg−1 combined with IVIg 2 g kg−1 in divided doses as first-line therapy in seven consecutive patients with acquired FVIII inhibitors. All patients were bleeding at the time of diagnosis with prolonged activated partial thromboplastin time. There were four complete responses, one partial response, one nonresponse and one with an inadequate follow-up for assessment of response, giving an overall response rate of 71%. In all complete responders the inhibitor declined rapidly and was undetectable by day 21 from start of treatment. Therapy was well tolerated and responses have been maintained off treatment for 2–8 months. This is a safe, well-tolerated rapidly acting regimen with good response rates.

    Notes: ATP2A2, the gene that is abnormal in Darier's disease, encodes SERCA2, a calcium pump that is expressed in many tissues. The wide expression of SERCA2 might suggest that ATP2A2 mutations would cause a multisystem disease. There is however, no evidence of consistent extracutaneous manifestations of Darier's disease. We have conducted preliminary studies in patients with Darier's disease, in two extracutaneous systems in which SERCA2 is known to be important, in order to investigate whether subtle defects have been overlooked. We found no evidence for altered cardiac function in 10 patients using two-dimensional, colour and Doppler echocardiography. There were no consistent defects in platelet function in 12 patients, using bleeding time and aggregation studies. We conclude that the skin is sensitive to defects in SERCA2 function to which other systems appear robust.

    Notes: The virC and virD operons of the virulence region of the Ti plasmid are highly regulated, requiring a transcriptional regulator that is encoded by virG and is activated by the product of virA and plant phenolics such as acetosyringone. Full expression of virC and virD of octopine and nopaline Ti plasmids is also obtained by a mutation in the ros gene of the Agrobacterium tumefaciens chromosome. S1-nuclease analysis, in vitro transcription, and DNase I protection experiments with A. tumefaciens RNA polymerase revealed virD promoters tandemly arranged, both of which are functional in the Ros mutant, while only one is functional in the presence of acetosyringone. A third (overlapping) promoter appears to be responsible for transcription of virC. Expression of virC and virD appears to be modulated by factors within the bacterium by means of a mechanism that is independent of factors produced during infection of the host plant.
