Objective: To compare the 6-month use rate of the etonogestrel implant placed immediately after dilation and evacuation (D&E) with placement 2-4 weeks postprocedure.
Methods: This is a randomized controlled trial of women seeking abortion between 14 0/7 and 23 5/7 weeks of gestation and desiring the etonogestrel contraceptive implant at an urban family planning clinic. Participants were randomized to device insertion immediately after the D&E compared with delayed insertion in 2-4 weeks.
In the past, victims of electrical and lightning injuries have been assessed in a manner lacking a systematic formulation, and against criteria, particularly in the area of neuropsychological disability. In this manner patients have, for example, only been partially treated, been poorly or incorrectly diagnosed, and have been denied the full benefit of compensation for their injuries. This paper contains a proposal for diagnostic criteria particularly for the neuropsychological aspects of the post injury syndrome.

On Lake Victoria, previous SWEW service trials ceased with the end of the funding grants.

Four of the girls and 4 of the dogs were killed. The 2 adults were unharmed, but all but 3 of the children suffered significant injuries.

Objective: To examine reliability and validity evidence of the Gastrointestinal Endoscopy Competency Assessment Tool (GiECAT) for colonoscopy for use within the clinical setting.
Design: Prospective, observational, multicenter validation study.
Objective: Gastrointestinal endoscopy is a complex task that involves an interaction of cognitive and manual skills. There is no consensus on the optimal way to teach endoscopy. We sought to evaluate our formal endoscopy curriculum for general surgery trainees to improve the effectiveness and quality of the endoscopy teaching in this program.

Flexible sigmoidoscopy has been shown to reduce the incidence and mortality of colorectal cancer in patients who are at average risk for this disease and, therefore, is an appropriate screening intervention. Moreover, it may be performed by nonphysicians.

Objective: By using Delphi methodology, we aimed to develop and establish the content validity of the Gastrointestinal Endoscopy Competency Assessment Tool for colonoscopy.
Design: An international panel of endoscopy experts rated potential checklist and global rating items for their importance as indicators of the competence of trainees learning to perform colonoscopy.
Objective: To present recommendations for the education, prevention, and management of lightning injuries for those involved in athletics or recreation.
Background: Lightning is the most common severe-storm activity encountered annually in the United States. The majority of lightning injuries can be prevented through an aggressive educational campaign, vacating outdoor activities before the lightning threat, and an understanding of the attributes of a safe place from the hazard.
Background: Previously developed screening colonoscopy algorithms based on diagnostic and endoscopy procedural variables have not been sufficiently accurate for use in epidemiological and health services research.
Objective: To increase understanding of the administrative health database variables that could help to discern screening and nonscreening colonoscopy.
Methods: A qualitative study using physician focus groups was conducted in Montreal (Quebec), Calgary (Alberta) and Toronto (Ontario).
Background: Helicobacter pylori is a WHO class I carcinogen also associated with nonmalignant gastrointestinal diseases. Effective treatment exists, and all persons infected with H pylori should receive treatment. However, data regarding the rates of treatment prescription in clinical practice are lacking.

However, there is no simple method to determine the colonoscopy indication using patient medical files or health administrative databases.
Objective: to determine patient-endoscopist agreement on the colonoscopy indication.
Objective: This study examines the prevalence of psychiatric morbidity in a large sample of electrical injury (EI) patients in three phases of recovery and its effects on cognitive functioning.
Methods: Eight-six self-referred EI patients received psychiatric and neuropsychological evaluations. Descriptive statistics were conducted to examine the prevalence of psychiatric morbidity.
Neuropsychological studies in electrical injury patients have reported deficits in attention, learning, and working memory, but the neural substrates of these deficits remain poorly characterized. In this study we sought to examine whether electrical injury subjects demonstrate abnormal patterns of brain activation during working memory and procedural learning tasks. Fourteen electrical injury subjects and fifteen demographically matched healthy control subjects performed a spatial working memory paradigm and a procedural learning paradigm during functional MRI studies.

Several screening options exist that can detect colorectal cancer at an early stage, leading to a more favourable prognosis. However, despite years of knowledge on best practice, screening rates are still very low in Canada, particularly in Ontario.

Data also support the clinical benefit of combination antiviral therapy in patients coinfected with HCV and HIV, and in patients who have received a liver transplant. Antiviral therapy with pegylated interferon-alpha and RBV is, however, associated with a high incidence and significant magnitude of anemia.

This is a unique case of a woman with worsening abdominal pain over 2 days with no clear etiology despite extensive, repeat evaluations with eventual spontaneous resolution. The diagnosis of chemical peritonitis was established when the patient revealed an extremely rare mechanism of injury the night before presentation that has never been described previously.

Sea-level control data were available between 3 and 8 weeks prior to the altitude sojourn for comparative purposes. Follow-up measurements were obtained for the same individual 3 weeks following the incident after simulated exposure to the combined stresses of inspiratory hypoxia and physical exercise.

The original question to be addressed was whether dalteparin was responsible for an acute rise in liver transaminases. The approach involved establishing a best possible diagnosis of the adverse event, obtaining a comprehensive history of drug exposure and evaluating the possible contributory role of alternate etiologies supported by a literature search.

Methods: A chart review was performed of patients admitted with LGI bleeding to Sunnybrook and Women's College Health Sciences Centre, Toronto, Ontario, between July 1, 1997 and January 31, 2000.
Results: Of 124 patients with LGI bleeding, 24 cases were due to ischemic colitis, 62 to diverticulosis, 11 to inflammatory bowel disease (IBD) and 27 to all other causes ('others').
