During a -4 year period, 1978-1981, 310 eyes of 301 patients living in the district of the Helsinki University Central Hospital were examined for rhegmatogenous detachment of the retina. This corresponds to an annual incidence of 6.9 per 100 000 mean population. The mean age of the patients was 54.2 years, and the sex distribution corresponded with that in(More)
To provide for early detection of abnormal changes in growth, we propose the monitoring of all children for changes in relative height and relative weight as indirect indicators of growth velocity. To this end we analyzed the growth of 2,156 children, as recorded by the child health surveillance services at ages 2 to 19 years. From their data we constructed(More)
Estrogen and progesterone receptors (ER/PR) were measured in primary tumors and metastases of 397 breast cancer patients. Survival following mastectomy was significantly longer in patients with ER and PR positive tumors, as was survival after first recurrence. The prognostic value of ER and PR was compared with such clinical factors as disease-free interval(More)
Anatomic and visual results of retinal detachment surgery were analyzed in 352 consecutive eyes operated on for rhegmatogenous type of retinal detachment in 1978-1981 at the University Eye Hospital in Helsinki. From 1978-79 to 1980-81, both the re-attachment rate and the visual results improved significantly (P less than 0.05). In the latter period, the(More)
A novel format for a growth chart is proposed to facilitate early detection of aberrant growth. Normal growth is shown as a horizontal line and any deviation from this indicates abnormal change in growth. The vertical scales show relative height (height SDS) and relative weight (% deviation of weight from the mean weight for height) directly. Weight is(More)
Data on the growth of 1063 children and their parents were analysed. Of the variation in height at prepuberty about 20%, and of the final height 30-46%, were explained by the variation in parental heights; the children's own height at the age of 1.0 year increased the proportion explained to half. Two equations were developed for increasing the accuracy of(More)
PURPOSE To get an informative and detailed picture of the resource utilization in a radiology department in order to support its pricing and management. MATERIAL AND METHODS A system based mainly on the theoretical foundations of activity-based costing (ABC) was designed, tested and compared with conventional costing. The study was performed at the(More)
Patients who use phenytoin and some other anticonvulsive drugs have been shown to have raised concentrations of plasma high density lipoprotein. As this lipoprotein is known to be inversely associated with the incidence of ischaemic heart disease the causes of death of all patients with epilepsy known to be taking anticonvulsive drugs who died during(More)
As part of our work aiming at facilitation of growth screening, we analyzed the growth of 741 healthy infants from birth to 2 years of age. We 1) show that weight depends on length rather than age, 2) present new growth standards in a format which allows direct reading of relative length and relative weight, and 3) define the normal variation of changes(More)
UNLABELLED In order to investigate whether there is an association between the HLA system and type 2 diabetes, we have determined HLA-A, B- and C-antigens in 227 patients with onset of diabetes between the ages of 35 and 70 years and compared them with the HLA-antigen frequencies in Finnish blood donors. One hundred and sixty-eight patients (74%) were(More)
