Influence of natural vs. anthropogenic stresses on water resource sustainability: a case study.

Climate change has been identified as a major influence on basin water balances. However, land use and water use practices have also been identified as players. This case study was completed to better understand a changing water balance affecting a major basin in Alberta. The Beaver River basin is located in east central Alberta. Much of the basin has been developed for agricultural use; however, a number of heavy oil operations also exist. Both sectors use surface and groundwater. Evidence exists that the basin hydrology has changed since the mid-1970s. Coincidently, it was at this time that much of the land was cleared for agricultural development and commercial-scale oil development began. Oil industry use of water was suspected as the main cause for the changes observed. To investigate this further, data from regional hydrometric and meteorological stations were assessed along with water well hydrographs and historical satellite images. A significant correlation was found between basin responses and a climate phenomenon known as the Pacific decadal oscillation. Although the correlation between the Pacific decadal oscillation and basin hydrology appeared strong, deforestation for agricultural development also seemed to have an effect. Use of the local water resources was found to be of minor significance.

Application of recombinant activated factor VII for treatment of impaired haemostasis during liver transplantation in recipients with Wilson's disease--a report of two cases.

Recombinant activated factor VII (rFVIIa, NovoSeven, Novo Nordisk A/S, Denmark) is a treatment used to prevent and arrest intra- and postoperative bleeding in patients with haemophilia A or B complicated by circulating anticoagulants (inhibitors of FVIII and FIX) and in patients without haemophilia who spontaneously develop inhibitors of FVIII, i.e. in acquired haemophilia. Patients who qualify for liver transplantation due to liver dysfunction may have varying degrees of coagulation impairment and thus carry an elevated risk of massive bleeding and have worse prognosis. The authors administered recombinant activated factor VII to two patients with coagulation abnormalities in the course of Wilson's disease during liver transplantation.

Assessment of methods of anaesthesia used for total alloplasty of hip joint with application of bone cement.

The authors analyse 151 cases of anaesthesia for total hip joint alloplasty. Fifty-three patients had general anaesthesia and in 98 cases epidural analgesia was performed. Although the statistical analysis of correlations between the fall of the arterial blood pressure and the age of patients failed to demonstrate significant differences between both types of anaesthesia the authors regard local analgesia as superior.

Hyperbaric oxygen in treatment of acute carbon monoxide poisoning.

During a period of 5 months 44 patients with acute carbon monoxide poisoning were treated with hyperbaric oxygen. In 80% of cases very good results were obtained. Analizing the causes of death the following factors were considered: the duration of exposure to carbon monoxide, the age of patients and the degree of unconsciousness at the time of hospital admission. The patients stayed in a hyperbaric chamber for 90 min. on the average. The mean pressure of 100% oxygen was 2.5 ATA. When lower pressures were applied the time necessary for elimination of the same amount of carbon monoxide from the organism was slightly prolonged, nevertheless, the use of lower pressures is recommended, since it reduced the risk of toxic effects on oxygen.

[Indications for and results of treatment of carotid artery stenosis].

The authors discuss own experience with the treatment of carotid artery stenosis. Diagnostic principles and indications to surgical treatment, technique of block anesthesia, an operation and obtained results are also discussed. Internal carotid artery stenosis was treated surgically in 90 patients within 1985-1988. Block anesthesia enabling intraoperational control of patients' consciousness was used in 72 cases. Satisfactory early results were noted in 92.9% of patients. Two patients died after surgery whereas 5 patients suffered from neurological complications. Favourable late results (follow-up period ranged from 6 to 48 months) were noted in 64 out of 70 patients which reported to clinical examination (91.4%).
