Clinical outcome of endoscopic treatment of symptomatic Hepaticojejunal anastomotic strictures after pancreatoduodenectomy.

Background: Hepaticojejunostomy anastomotic stricture (HJAS) is an adverse event after pancreatoduodenectomy (PD) which can result in jaundice and/or cholangitis. With endoscopy, HJAS can be managed. However, few studies report the specific success and adverse event rates of endoscopic therapy after PD.

Exposure of uninfected poultry farms to HPAI (H7N7) virus by professionals during outbreak control activities.

With an extensive data set on visits made to control the H7N7 avian influenza epidemic in The Netherlands in 2003 we investigate the potential role of the persons involved in the control activities as vectors for disease transmission. We hypothesized that people can spread the virus on the same day mechanically, or till 10 days if they have become infected themselves. Taken into account was the estimated time of introduction of the virus into a poultry flock back-calculated from mortality data.

High probability of avian influenza virus (H7N7) transmission from poultry to humans active in disease control on infected farms.

An epizootic of avian influenza (H7N7) caused a large number of human infections in The Netherlands in 2003. We used data from this epizootic to estimate infection probabilities for persons involved in disease control on infected farms. Analyses were based on databases containing information on the infected farms, person-visits to these farms, and exposure variables (number of birds present, housing type, poultry type, depopulation method, period during epizootic).

Case-control study on the association between a cluster of childhood haematopoietic malignancies and local environmental factors in Aalsmeer, The Netherlands.

Study Objective And Design: In Aalsmeer, a horticultural community near the main international airport in The Netherlands, a more than fourfold increase in the incidence of haematopoietic malignancies in young people was observed between 1980 and 1985. In a population based case-control study, the association with local environmental factors was investigated.

Participants: For each patient younger than 40 years of age (n = 14) diagnosed between 1975 and 1989, four age and sex matched controls were selected via local general practitioners.

[Case control study of the relationship between local environmental factors and hematopoietic malignancies in young subjects in Aalsmeer].

In Aalsmeer, a horticultural community near the main international airport in the Netherlands, an incidence of haematopoietic malignancies in young people over four times the national mean was observed in the period 1980-1985. A population based case-control study investigated the association with local environmental factors. For each case younger than 40 years of age (n = 14), diagnosed between 1975 and 1989, four controls, matched for age and gender, were selected via local general practitioners.
