Selected AbstractsFuture eating and country keeping: what role has environmental history in the management of biodiversity?JOURNAL OF BIOGEOGRAPHY, Issue 5 2001D.M.J.S. Bowman In order to understand and moderate the effects of the accelerating rate of global environmental change land managers and ecologists must not only think beyond their local environment but also put their problems into a historical context. It is intuitively obvious that historians should be natural allies of ecologists and land managers as they struggle to maintain biodiversity and landscape health. Indeed, ,environmental history' is an emerging field where the previously disparate intellectual traditions of ecology and history intersect to create a new and fundamentally interdisciplinary field of inquiry. Environmental history is rapidly becoming an important field displacing many older environmentally focused academic disciplines as well as capturing the public imagination. By drawing on Australian experience I explore the role of ,environmental history' in managing biodiversity. First I consider some of the similarities and differences of the ecological and historical approaches to the history of the environment. Then I review two central questions in Australian environment history: landscape-scale changes in woody vegetation cover since European settlement and the extinction of the marsupials in both historical and pre-historical time. These case studies demonstrate that environmental historians can reach conflicting interpretations despite using essentially the same data. The popular success of some environmental histories hinges on the fact that they narrate a compelling story concerning human relationships and human value judgements about landscape change. Ecologists must learn to harness the power of environmental history narratives to bolster land management practices designed to conserve biological heritage. They can do this by using various currently popular environmental histories as a point of departure for future research, for instance by testing the veracity of competing interpretations of landscape-scale change in woody vegetation cover. They also need to learn how to write parables that communicate their research findings to land managers and the general public. However, no matter how sociologically or psychologically satisfying a particular environmental historical narrative might be, it must be willing to be superseded with new stories that incorporate the latest research discoveries and that reflects changing social values of nature. It is contrary to a rational and publicly acceptable approach to land management to read a particular story as revealing the absolute truth.

Results: The operation was uneventful and the patient was discharged from the hospital on the 4th postoperative day. Conclusion: Transpulmonary route for the closure of the PDA by using CPB is a safe and acceptable approach in adult patients. [source] Role of Surgical Salvage for Regional Recurrence in Laryngeal CancerTHE LARYNGOSCOPE, Issue 1 2007Woo-Jin Jeong MD Abstract Objectives: The aims of this study were to analyze the pattern of regional recurrence in laryngeal cancer, evaluate the role of surgical salvage, and identify factors affecting salvage outcome. Methods: Retrospective analysis was conducted on medical records from a 16-year period. Of 463 patients diagnosed with laryngeal cancer, 25 patients with regional recurrence managed with salvage neck dissection were identified and subject to study. Isolated local recurrences and all distant metastases were excluded. Results: All patients were male with a median age of 61 years. The overall rate of regional recurrence was 5.4%. Median time to regional recurrence was 13 months. Isolated regional recurrence occurred in 76% of cases, whereas locoregional recurrence occurred in 24%. A 5-year survival rate for patients undergoing neck dissection as salvage management was 61.2%. Patients with recurrence in the contralateral neck were definitely associated with poor prognosis. Although standard statistical significance was not met, trends for poorer salvage result were identified in patients with a history of local recurrence before regional recurrence, recurrence in a previously dissected neck, and recurred node size of 3 cm or above. Conclusions: Our study shows that salvage neck dissection for regional recurrence in laryngeal cancer is an acceptable approach. Surgical eradication of disease should be warranted whenever possible. Prudent planning of management is mandatory in the presence of history of local recurrence before regional recurrence, previously dissected neck, large size of recurrent node, and contralateral neck recurrence. [source] Changing patterns in the management of gastric volvulus over 14 yearsBRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 3 2000W. J. Teague Background: Gastric volvulus is an uncommon condition, which can be difficult to diagnose and treat. This study represents a large series of patients with the condition. Methods: All patients presenting with gastric volvulus over a 14-year period were reviewed. Results: Some 36 patients (median age 75 years) were identified. Volvulus, usually secondary to a hiatus hernia, presented acutely in 29 patients. The major symptoms were abdominal pain, vomiting and upper gastrointestinal haemorrhage. The most useful investigations were barium contrast studies and upper gastrointestinal endoscopy, which were helpful in 21 of 25 and 11 of 18 patients respectively. Treatment was conservative in five patients, by open surgery in 13 and laparoscopic repair in 18 (three converted to open operation). There were no major complications and no deaths. Median hospital stay was shorter in patients treated by laparoscopic rather than open surgery (6 (range 4,36) versus 14 (7,50) days; P < 0·05). Conclusion: Acute and chronic gastric volvulus can be treated successfully by either open or laparoscopic surgery. However, laparoscopic surgery now represents a safe and acceptable approach, with minimal morbidity and a significantly shorter hospital stay. This is likely to be of considerable benefit for the treatment of a predominantly elderly population, often with significant co-morbidity. © 2000 British Journal of Surgery Society Ltd [source] | ||||||||||
