BACKGROUND Problems in the management of thoracic trauma have stimulated the search for an alternative to underwater seals for drainage of the pleural cavity. A chest drainage bag incorporating a one way flutter valve has been compared with underwater seal drains in a randomised clinical trial. METHODS During June-December 1989 119 patients undergoing elective thoracotomy were randomised to r...

OBJECTIVE Drains and catheters are used for both prophylactic and therapeutic reasons in clinical practice. This study aimed to investigate the factors that affect safety of drains, catheters, nasogastric tube and central venous line in patients who underwent surgery. MATERIAL AND METHODS Two hundred and four consecutive patients who were operated at the general surgery clinics under general ...

BACKGROUND Cervical drains have historically been used to avoid postoperative wound and respiratory complications such as excessive edema, hematoma, infection, re-intubation, delayed extubation, or respiratory distress. Recently, some surgeons have ceased using drains because they may prolong hospital stay, operative time, or patient discomfort. The objective of this retrospective case-control ...

Tile drained land with phosphorus (P)-rich topsoil is prone to P loss, which can impair surface water quality via eutrophication. We used by-products from steel and energy industries to mitigate P loss from tile drains. For each by-product, P sorption maximum (P(max)) and strength (k) were determined, while a fluvarium trial assessed P uptake with flow rate. Although two ash materials (fly ash ...

OBJECTIVE To describe the management and impact of pancreatic fistulas in a high-volume center. DESIGN Retrospective case series. SETTING Tertiary academic center. PATIENTS Five hundred eighty-one consecutive patients who underwent pancreaticoduodenectomy from January 2001 through June 2006. MAIN OUTCOME MEASURES Development of a pancreatic fistula (defined as > 30 mL of amylase-rich fl...

An important tool in environmental management projects and studies due to the complexity of environmental systems, environmental modeling makes it possible to integrate many variables and processes, thereby providing a dynamic view of systems. In this study the bacteriological quality of the coastal waters of Fortaleza (a state capital in Northeastern Brazil) was modeled considering multiple co...

OBJECTIVE To determine whether two low dose aprotinin regimens produce clinically significant reductions in postoperative blood loss compared with a control group. DESIGN A randomised double blind placebo controlled study. SETTING A regional cardiothoracic unit in London. PATIENTS 79 patients were consecutively allocated to one of three groups. All patients had primary elective surgery wi...

In dengue-endemic areas, transmission shows both a seasonal and interannual variability. To investigate how rainfall impacts dengue seasonality in Singapore, we carried out a longitudinal survey in the Geylang neighborhood from August 2014 to August 2015. The survey comprised of twice-weekly random inspections to outdoor breeding habitats and continuous monitoring for positive ones. In addition...
