Background: Little is understood of Ebola virus disease (EVD) transmission dynamics and community compliance with control measures over time. Understanding these interactions is essential if interventions are to be effective in future outbreaks. We conducted a mixed-methods study to explore these factors in a rural village that experienced sustained EVD transmission in Kailahun District, Sierra Leone.

In December 2014, MSF opened an EMC in Tonkolili District (district EMC). We examined the effect of opening a district-based EMC on time to admission and number of suspect cases dead on arrival (DOA), and identified factors associated with fatality in EVD patients, residents in Tonkolili District.

Ebola Virus Disease (EVD) was first detected in Sierra Leone in May 2014 in Kailahun district. Despite high case numbers elsewhere in the country, transmission was eliminated in the district by December 2014.

Methods: Weekly adult female Ae. aegypti data were obtained from 79 double sticky ovitraps (SOs) located in Cairns for the period September 2007-May 2012.
This review provides details on the role of Geographical Information Systems (GIS) in current dengue surveillance systems and focuses on the application of open access GIS technology to emphasize its importance in developing countries, where the dengue burden is greatest. It also advocates for increased international collaboration in transboundary disease surveillance to confront the emerging global challenge of dengue.

Background: Laparoscopic adjustable gastric banding (LAGB) fails in 5% of patients due to band-related complications or patient intolerance. A subset of patients subsequently managed with biliopancreatic diversion (BPD) have failed to achieve a percentage of excess weight loss (%EWL) > 50% or a body mass index (BMI) < 35 kg/m(2) even after a further procedure shortening the common channel to 30 cm.
Method: A computerized obesity database was used to identify the study group and collect preoperative and outcome data.

Background: Severely obese adolescents are suffering all the consequences well known in adults. A decision was made to offer laparoscopic adjustable gastric band surgery to severely obese adolescents.
Methods: This retrospective study reviewed the outcomes of 41 adolescents aged 12-19 years (mean 15.
Background: Concerns still exist about the long-term effectiveness and rate of retention of the laparoscopic adjustable gastric band (LAGB). Furthermore, esophageal dilatation has been suggested as a long-term complication for LAGB. We therefore sought to objectively analyze our follow-up results in patients with LAGB performed in 1998 by perigastric technique and 2000 by pars flaccida technique.
