Submucosal hematoma: a new distinctive sign during emergency upper digestive endoscopy for ammonia ingestion.

Background: Submucosal hematoma has never been associated with caustic injuries. Long-term follow-up of patients who ingested ammonia is not well known and ammonia ingestion is rare.

Methods: In a Single-center observational study, prospective data were collected from 2009 to 2013, in patients over the age of 14 years old referred for ammonia ingestion.

Major salivary gland aplasia and hypoplasia in Down syndrome: review of the literature and report of a case.

Salivary gland aplasia and hypoplasia are rarely described in the medical literature. This article presents a case of aplasia and hypoplasia of the major salivary glands in a patient with Down syndrome. A literature review, as well as an overview of the diagnosis and management of this condition, is presented.

[Wernicke's encephalopathy following sleeve gastrectomy for morbid obesity].

Introduction: Bariatric restrictive interventions, as sleeve gastrectomy or gastric banding can cause metabolic complications, especially when vomiting is present, such as thiamine deficiency that can lead to Wernicke's encephalopathy.

Case Report: A 31-year-old man with a 47kg/m(2) body mass index presented with Wernicke's encephalopathy, with ophtalmoplegia, nystagmus, ataxia and confusion, followed by a Korsakoff syndrome, occurring two months after a sleeve gastrectomy. MRI showed hyperintense signals on T2 and FLAIR image in both thalamus, periaqueducal area and mamillary bodies.

Seroepidemiology of chronic hepatitis B and C in the French Caribbean Island of Guadeloupe.

Background: The prevalence of chronic hepatitis B and C was evaluated some twenty years ago among specific populations in Guadeloupe. The present study was designed to update these data and determine epidemiological features of chronic hepatitis B and C infections in the French Caribbean island of Guadeloupe.

Findings: The present study was carried out at the Sainte Genevieve Health and Prevention Center (Guadeloupe), between May 2006 and July 2007.

Percutaneous transluminal angioplasty of the lower abdominal aorta.

Percutaneous transluminal angioplasty (PTA) of the lower abdominal aorta was performed in 14 patients aged 29-66 years (mean, 50). The disease was largely isolated to the distal aorta in this group. There were 13 women and 1 man; all were heavy smokers.

Safety of outpatient angiography: a prospective study.

A prospective study of 100 consecutive outpatient angiograms with catheters on rapid changers was undertaken to ascertain the safety of this protocol. Ninety-four patients could be discharged after a 4 hr surveillance and were still well 1 week later; six patients had to be observed up to 24 hr for minor problems and one was hospitalized the night after his angiogram, for a renal complication. This approach to angiography, emphasizing the outpatient status, seems to be safe and should deserve widespread acceptance.

[Compulsory internship in diagnostic radiology in the 5th year of medicine at the University of Montreal].

Problems of methodology, organization, and evaluation confronting the radiology departments of the university hospitals affiliated with the University of Montreal, the medical students, and the University itself in connection with an elective internship in radiology offered in the fifth year of medicine, resulted in the formation of a committee to reorganize the course of study. In this concise article the authors describe this and other measures taken by the University to solve these problems. The committees' main purpose was to restructure the internship which was made compulsory so that future physicians would be prepared to draw on the resources of diagnostic radiology and nuclear medicine.

Undergraduate radiology clerkship: the Universite de Montreal program.

At the Université de Montréal, a four-week rotation in radiology is part of the core curriculum for students in their fifth and final year of medicine. The objective of this undergraduate radiology clerkship is to prepare the future physician to use efficiently the resources of radiology and nuclear medicine in patient care. Specific goals and methods used to achieve them are described and analysed.
