The dental X-ray file of crew members in the Scandinavian Airlines System (SAS).

In 1977, the Scandinavian Airlines System (SAS) established a dental X-ray file of all crew members. Its aim was to have immediately available an adequate set of physical antemortem data useful for identification in case of a fatal crash. Recently, an investigation into the quality and suitability of this material was carried out. The radiographs of 100 Danish, 100 Norwegian, and 100 Swedish pilots were picked at random and evaluated for formal deficiences, technical deficiencies, treatment pattern as useful for identification purposes, and the presence of pathology. The major results of the investigation were that a number of formal and technical deficiencies were disclosed, that the treatment pattern would seem adequate for identification purposes, and that a number of pathological findings were made, several of which had to be considered possible safety risks in the form of barodontalgia.

Up-to-date denominators: evaluation of taxation family file for public health planning.

Public Health agencies need up-to-date population data, and Statistics Canada's Taxation Family File (T1FF) database, developed annually from T1 personal income tax forms, may meet this need. We compared 1989 T1FF data for Ottawa-Carleton with census data. The overall population estimate for the region was 98% of the census figure. Equivalent figures were 94% for central cities, 98% for suburbs and 122% for rural areas. The T1FF underestimated the population of children (89%) and seniors (93%). Population estimates for smaller neighbourhoods were poorer, some being wrong by a factor of more than two. The errors are probably due to postal code conversion. The T1FF provides fairly accurate estimates of the population of larger areas, and can be much more current than census data. It is less accurate for smaller areas, offers a limited range of variables, does not specify gender for children, and is fairly expensive. Health units with a major commitment to needs-based planning should consider using the T1FF for denominator data, despite its limitations.

Completeness of provincial workers' compensation files to identify fatal occupational injuries.

The objective of the study was to ascertain the completeness of Workers' Compensation files to identify fatal occupational injuries. The number of fatalities was counted using two independent sources: the Quebec Workers' Compensation Board (QWCB), and the Coroner's Death Certificates (CDCs), for the years 1987 and 1988. The observed number of cases was 352. The QWCB identified 83.8% of those and CDCs 69.3%. The true number of deaths was estimated, using the capture-recapture methods, to be between 369 and 401. The compensation coverage of work-related fatalities was 66.1% in workers 55 years of age and older and 8.3% in farming occupations. Therefore, Workers' Compensation statistics are inadequate as the single source in these two categories and their exclusive use thus far has led to a failure in recognizing these issues as public health priorities.

Social insurance cost of standard discectomy and percutaneous nucleotomy. A retrospective study of 87 social insurance claim files of male blue collar workers.

A retrospective review of social insurance claim files of male blue collar workers was conducted to compare the social insurance costs of percutaneous lumbar nucleotomy with standard lumbar discectomy ; 29 percutaneous nucleotomy procedures were matched with 58 standard discectomies all carried out between January 1992 and December 1994. It was concluded that a standard discectomy procedure results in significantly higher costs during hospitalisation with respect to surgery, anaesthesia and hospital stay. A percutaneous nucleotomy leads to a significantly higher outpatient expenditure especially in radiology and medical devices. The relative proportion of outpatient practitioner's visits and hospital stay costs was significantly higher for the standard discectomy whereas medical devices had a relatively higher share in outpatient expenditure for the percutaneous nucleotomy. In this population of 87 compensation claimants, the average social insurance costs did not significantly differ between the percutaneous nucleotomy and the standard discectomy.

[Registration files on the dispensary coverage of the population].

To-day the quality of treatment on the dispensary levels is the most important factor in the work of medico-prophylactic establishments. The existing registration files on the dispensary coverage of thee population needs revision with a view of satisfying requirements of practicians. The organizational-methodological division of th Lvov regional clinical hospital has devised an optimal variant of registration forms that enable it to ensure keeping more exact records of patients undergoing the dispendary treatment, to cut down the time spend in checking, to more quickly obtain the needed current data and to strike balance of the medical commissions work in carrying out periodical medical examinations of the population.

[Etiological work-up of complex voiding disorders (CVD) in boys; evaluation of the imaging strategy based on a retrospective study of 58 files].

The strategy of radiological investigations in males with severe voiding disorders has not been clearly established. To define the most effective strategy, a retrospective study of 58 files of boys investigated for severe voiding disorders (excluding neurogenic bladder) was performed. The following investigations were performed in this series: intravenous urography (IVU) completed by voiding cystourethrogram (VCUG) (41%), VCUG alone or associated with urinary ultrasound (30%), IVU alone (20.5%) ultrasound alone (1.5%) and ultrasound completed by VCUG or IVU (7%). When prescribed first, VCUG was always sufficient for accurate diagnosis; in contrast, a second investigation was usually necessary when IVU (66%) or ultrasound (80%) were performed first. The interpretability of the voiding urethrogram was also higher with VCUG (90%) than with IVU (66%); the sensitivity was 94% for VCUG and only 69% for IVU and 8% for ultrasound. This study confirms that VCUG combined with urinary ultrasound is the most reliable way to radiologically investigate male severe voiding disorders.
