Cancer of the esophagus and gastric cardia: recent advances,

DISEASES OF THE ESOPHAGUS, Issue 1 2004
G. N. J. Tytgat
SUMMARY., Esophageal cancer and cancer of the gastric cardia, in particular adenocarcinomas, have shown a rapid and largely unexplained increase in incidence in many developed countries around the world. These diseases have a poor prognosis and current therapies have a modest impact on survival. This review presents recent advances in the epidemiology, etiology, diagnosis, staging, prevention and treatment of resectable and advanced disease. Although significant progress has been made in these areas of research and patient management over the past years, prognosis for most patients diagnosed with esophageal cancer or cancer of the gastric cardia remains poor. New diagnostic procedures, improved surgical procedures, combined treatment modalities and new treatment modalities are being evaluated and may be expected to contribute to improved patient outcomes and better palliation of symptoms in the future.

Psychometric characteristics of Cloninger's criteria for personality disorder in a population of French prisoners

INTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 1 2008
Antoine Pelissolo
Abstract Cloninger has proposed a new procedure to assess personality disorders on the basis of his model of temperament and character. We explored the psychometric characteristics of this instrument in 560 male prisoners, using factor analyses. Results showed that the 20 items relating to the general personality criteria have acceptable internal consistency and that the three-factor structure of the temperament items used to subtype personality disorder are correctly identified by a maximum likelihood factor analysis model with varimax rotation. Overall, 32% of prisoners had a personality disorder according to this model, and it was possible to subtype 68% of these. This new diagnostic procedure for personality disorder seemed to have satisfactory basic psychometric characteristics but further study is required to explore the concurrent validity and the reliability of this instrument.

Validation of a new diagnostic procedure for DSM IV axis I disorders

INTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 3 2002
Jean-Yves Loze
Abstract Despite the fact that, in today's psychiatric research and especially in epidemiological studies, diagnostic assessments are made with reliable standardized clinical interviews, recent articles have shown discrepancies in prevalence rates of DSM IV axis I disorders assessed with different, yet reliable, clinical standardized interviews, raising the problem of the clinical relevance of some of these instruments. Within an epidemiological study, we developed a simple method for evaluating DSM IV axis I disorders with the aim of improving the clinical relevance of assessed diagnoses. This method is based on an evaluation performed by two clinicians. The first one used a short structured clinical interview (MINI v 5.0) and the second one completed the procedure with an open clinical interview, intended to be more clinically relevant. Finally, a consensus diagnosis is given by the two investigators. We conducted a survey in order to validate this method by measuring the agreement of diagnoses reported by two pairs of clinicians on a population of 20 inpatients. Results show that this double evaluation led to a high agreement (kappa ranging between 0.76 and 1.00) suggesting that the proposed evaluation procedure, which is intended to be more clinically relevant, is also highly reliable.

Testing Equality between Two Diagnostic Procedures in Paired-Sample Ordinal Data

BIOMETRICAL JOURNAL, Issue 6 2004
Kung-Jong Lui
Abstract When a new diagnostic procedure is developed, it is important to assess whether the diagnostic accuracy of the new procedure is different from that of the standard procedure. For paired-sample ordinal data, this paper develops two test statistics for testing equality of the diagnostic accuracy between two procedures without assuming any parametric models. One is derived on the basis of the probability of correctly identifying the case for a randomly selected pair of a case and a non-case over all possible cutoff points, and the other is derived on the basis of the sensitivity and specificity directly. To illustrate the practical use of the proposed test procedures, this paper includes an example regarding the use of digitized and plain films for screening breast cancer. This paper also applies Monte Carlo simulation to evaluate the finite sample performance of the two statistics developed here and notes that they can perform well in a variety of situations.

International medical graduates: Learning for practice in Alberta, Canada

THE JOURNAL OF CONTINUING EDUCATION IN THE HEALTH PROFESSIONS, Issue 3 2007
Jocelyn Lockyer PhD
Abstract Introduction: There is little known about the learning that is undertaken by physicians who graduate from a World Health Organization,listed medical school outside Canada and who migrate to Canada to practice. What do physicians learn and what resources do they access in adapting to practice in Alberta, a province of Canada? Methods: Telephone interviews with a theoretical sample of 19 IMG physicians were analyzed using a grounded theory constant comparative approach to develop categories, central themes, and a descriptive model. Results: The physicians described two types of learning: learning associated with studying for Canadian examinations required to remain and practice in the province and learning that was required to succeed at clinical work in a new setting. This second type of learning included regulations and systems, patient expectations, new disease profiles, new medications, new diagnostic procedures, and managing the referral process. The physicians "settled" into their new setting with the help of colleagues; the Internet, personal digital assistants (PDAs), and computers; reading; and continuing medical education programs. Patients both stimulated learning and were a resource for learning. Discussion: Settling into Alberta, Canada, physicians accommodated and adjusted to their settings with learning activities related to the clinical problems and situations that presented themselves. Collegial support in host communities appeared to be a critical dimension in how well physicians adjusted. The results suggest that mentoring programs may be a way of facilitating settlement. [source]
