Development of the French-Canadian Version of the Self-Administered Comorbidities Questionnaire (SCQ) in a hospital population undergoing hip or knee arthroplasty.

Unlabelled: The Self-Administered Comorbidity Questionnaire (SCQ) is a tool used by hospitalized patients to self-report their comorbidities. It can help to explain the effectiveness of hip or knee arthroplasty, its complications, the length of hospital stay and perioperative resource utilization.

Hypothesis: The French-Canadian version of the SCQ will be suitable for use in a Canadian hospital population.

The primary purpose is to translate and assess the transcultural validity of the RAPT - a pre-operation questionnaire that helps predict the clients' post-operation process - for the French-Canadian population requiring an arthroplasty of the hip or of the knee. The second purpose is to determine the standard error of measurements of the French-Canadian version of RAPT. The transcultural translation and adaptation process of RAPT follows four steps: (1) initial translation, (2) retro-translation, (3) assessment of the questionnaire's clarity by patients, 4) assessment of the translation's transcultural validity.

SPIRALE: a multispecies in situ balloonborne instrument with six tunable diode laser spectrometers.

The balloonborne SPIRALE (a French acronym for infrared absorption spectroscopy by tunable diode lasers) instrument has been developed for in situ measurements of several tracer and chemically active species in the stratosphere. Laser absorption takes place in an open Herriott multipass cell located under the balloon gondola, with six lead salt diode lasers as light sources. One mirror is located at the extremity of a deployable mast 3.

Giant cell tumor of long bone: a Canadian Sarcoma Group study.

A multicentric retrospective study of giant cell tumor of bone was conducted among Canadian surgeons. The hypothesis was that no differences would be found in health status, function, or recurrence rate irrespective to the nature of filling material or adjuvant used in patients treated with curettage. One hundred eighty-six cases were collected.
