Double balloon enteroscopy in children:Diagnosis,treatment,and safety

AIM:To assess the feasibility and utility of double balloon enteroscopy(DBE)in the management of small bowel diseases in children. METHODS:Fourteen patients(10 males)with a median age of 12.9 years(range 8.1-16.7)underwent DBE; 5 for Peutz-Jeghers syndrome(PJ syndrome),2 for chronic abdominal pain,4 for obscure gastrointestinal (GI)bleeding,2 with angiomatous malformations(1 blue rubber bleb nevus syndrome)having persistent GI bleeding,and 1 with Cowden‘s syndrome with multiple polyps and previous intussusc...

The character and value of vernacular security: the case of South West Cameroon

ABSTRACT

This article reports the findings of field research into the vernacular understanding of security in South West Cameroon. It was found that security significantly contested; it is both objective and subjective; it is communal, whilst at the same time requiring individual l responsibility of personal security; it favours certainty and stability; it draws on a multiplicity of providers, and it goes beyond traditional conceptualisations. The findings make it clear that there are wide divergences between the typical state and donor driven security reform programmes, and people’s perceived security needs. The definition of security is challenged by popular understandings. In addition, though not rejecting the need for state security, it is evident that many more actors are engaged in security provision and personal safety than state actors, and that these actors need to be accounted for in reform programmes. Conclusion draw out advantages of the vernacular approach in security reform programmes.     

Spatial Distributions of Oxygen Stable Isotope Ratios in Tap Water From Mexico for Region of Origin Predictions of Unidentified Border Crossers

One of the many difficulties associated with identifying undocumented border crossers stems from an inability to narrow down the search area for the region of origin and family members to obtain family reference samples for DNA comparison. While the geography of regions of origins is wide, the biological profiles of the undocumented border crossers often show strong similarities, young and male. The isotopic composition of human bones, teeth, and hair has been demonstrated to be useful biomarkers for tracing locations and movements of individuals and for aiding in the identification of human remains. Data obtained from human remains can be compared to and aligned with various reference sources, such as soils and bedrock, archaeological remains, or cultural data. Here, the spatial deficiency in isotopic reference data for Mexico, specifically for oxygen (δ¹⁸O) isotopes in tap water, is being addressed through the collection and analysis of over 150 water samples and explored with tooth enamel isotopic values from recently identified Mexican nationals. The isoscape was developed using a Spine with Barriers interpolation method and shows sufficient detail to narrow down the regions where specific isotopic values are represented. The individuals were plotted on the developed isoscape using conditional correlations. The methodology was successful in assigning the correct regions of origin for the two individuals, which shows the tremendous potential of the developed isoscape. Nonetheless, there is more research needed to further improve upon this geolocation method, including analysis of multiple isotopes in different tissues, and the development of new isotopic methods.
