Abstract

We prove a conjecture formulated by Pablo M. Chacon and Guillermo A. Lobos in [Pseudo-parallel Lagrangian submanifolds in complex space forms, Differential Geom. Appl.] stating that every Lagrangian pseudo-parallel submanifold of a complex space form of dimension at least 3 is semi-parallel.

Abstract

Background Chronic subdural haematoma (CSDH) is a pathology that is frequently encountered by neurosurgeons. Nevertheless, there is a lack of guidelines based on solid evidence. There has been a recent and considerable increase in the interest on management and outcomes for CSDH. Therefore, we systematically reviewed all currently running randomised controlled trials (RCTs) in chronic subdural haematoma to understand the areas under investigation and plan future collaborative trials. Methods Clinical trials databases (Cochrane Controlled Register of Trials, WHO ICTRP and clinical ) were searched for trials relevant to chronic subdural haematoma. It was then established which trials were currently running and fulfilled robust research methodology for a RCT. Results There are 26 currently running RCTs in CSDH, with the most common topics covering application of steroids (7), surgical techniques (5) and tranexamic acid (5). Further to this, there are trials running on other pharmacological agents (4), middle meningeal artery (MMA) embolisation (2) and peri-operative management (3). Conclusions Pharmacological agents are a particular focus of CSDH management currently, and a wealth of studies on steroids will hopefully lead to more harmonised, evidence-based practice regarding this in the near future. Surgical techniques and new procedures such as MMA embolisation are also important focuses for improving patient outcomes. There is an on-going need for future RCTs and evidence-based guidelines in CSDH, particularly including low- and middle-income countries, and it is hoped that the establishment of the iCORIC (International COllaborative Research Initiative on Chronic Subdural Haematoma) will help address this.

Abstract

Unlabelled: The aim of this study was to evaluate the bronchodilating capacity of nebulized oxitropium bromide (OB) in preschool asthmatic children and to determine an appropriate dose for usage in this age group. The trial enrolled 20 patients with moderate to severe stable asthma aged between 3.2 and 6.2 years (mean 4.7). Applying a placebo controlled, double-blind design, the effect of placebo was compared with three different doses of OB (375, 750 and 1500 micrograms) and with 400 micrograms fenoterol. The three different doses of OB resulted in a highly significant bronchodilation within 15 min after administration. The observed bronchodilation was comparable between the three doses during the first 2 h. However, after 4 h the lowest dose was significantly less powerful than the highest dose. Compared to the additional bronchodilation induced by fenoterol, no difference was found with the degree of bronchodilation of OB which occurred during the first 2 h. Furthermore, after 4 h only the lowest dose of OB was significantly less powerful than fenoterol assessed 10 min following a single 400 micrograms dose.Conclusion: Oxitropium bromide is a potent and long-acting bronchodilator in preschool children at a dose of 750 micrograms and 1500 micrograms. No side-effects were observed. The exact duration of action remains uncertain, but even 4 h after inhaling 750 or 1500 micrograms of OB no additive bronchodilation induced by fenoterol could be observed. [ABSTRACT FROM AUTHOR]

37. Declining trends in some sexually transmitted diseases in Belgium between 1983 and 1989.

Author

Walckiers, D, Piot, P, Stroobant, A, Van der Veken, J, and Declercq, E

Abstract

OBJECTIVE--To examine trends in some sexually transmitted diseases in Belgium and to discuss them in the light of the European background. DESIGN--Analysis of the time trends of C trachomatis and N gonorrhoeae infections diagnosed by a network of microbiological laboratories, and of male urethritis diagnosed by a network of general practitioners. SETTING--Belgium. SUBJECTS--Reports of C trachomatis and N gonorrhoeae infections by a network of microbiological laboratories, and of male urethritis by a network of general practitioners, to the Institute of Hygiene and Epidemiology. RESULTS--Whereas an increase in the number of C trachomatis infections, more pronounced among women, was observed up to 1986, a small decrease has been observed afterwards in males. The mean number of chlamydial infections per laboratory and per year was 4.2 in 1983, 15.7 in 1986 and 13.9 in 1989. A decrease in the number of N gonorrhoeae infections, more pronounced among men, has been observed. The mean number of cases of gonorrhoea per laboratory and per year was 10.9 in 1983 and only 2.2 in 1989. The same declining trend has been observed in another surveillance programme of male urethritis, based on a network of general practitioners. The number of cases of male urethritis per 100 patient encounters went down from 0.06 in 1982-3 to 0.04 in 1988-9. CONCLUSION--The declining trend in Western Europe in incidence of gonococcal infections and of urethritis in men is also occurring in Belgium, but genital chlamydial infections remain an important public health problem.
