The treatment-mix, treatment time, and dental status of 268 male industrial workers entitled to employer-provided dental care were studied. The data were collected from treatment records of the covered workers over the 5-year period 1989-93. Treatment time was based on clinical treatment time recorded per patient visit, and the treatment procedure codes were reclassified into a treatment-mix according to American Dental Association categories, with a modification combining endodontics and restorative treatment. The mean number of check-ups followed by prescribed treatment (treatment courses) during the 5 years was 3.7 among those who had entered the in-house dental care program prior to the monitored period (old attenders). Their treatment time was stable, 57-63 min per year, while the first-year mean treatment time (170 min) of those who had entered the program during the study period (new attenders) was significantly higher (P
The Finnish National Programme for Chronic Bronchitis and Chronic Obstructive Pulmonary Disease (COPD) 1998-2007 was set up to reduce the prevalence of COPD, improve COPD diagnosis and care, reduce the number of moderate to severe cases of the disease, and reduce hospitalisations and treatment costs due to COPD. Over 900 events for 25,000 participating healthcare workers were arranged. The major strengths of this programme included multidisciplinary strategies and web-based guidelines in nearly all primary health care centres around the country.
Data from national registries, epidemiological studies and questionnaires were used to measure whether the goals had been reached.
The prevalence of COPD remained unchanged. Smoking decreased in males from 30% to 26% (p

The objective of the study was to examine the coverage of the sealing program on first permanent molars (FPMs) and second permanent molars (SPMs) and first and second premolars (FSPMs), as well as to monitor the fate of the sealed teeth over time. All patients born in 1977 who had had regular check-ups in the Varkaus Health Center, Finland (n = 166) were included in the 1996 study. Data on the annual state of each tooth had been collected retrospectively since 1983. The coverage for the sealant program was 95%, 92%, and 6% of the FPMs, SPMs, and FSPMs, respectively. Out of the FPMs sealed at age 6 years, 28% were subjected to resealing, 13% developed occlusal, and 15% proximal caries during a 13-year follow-up period. From the SPMs sealed at age 11 years, 24% were subjected to resealing, 4% developed occlusal caries, and less than 2% proximal caries during the 9-year follow-up. None of the sealed FSPMs and only 1% of the non-sealed ones developed occlusal caries during the 9-year period. The mean DMF in the study population (n = 160) at age 12 years was 0.8 (n = 124), compared to a nation-wide mean value of 1.2. A large percentage of the FPMs and SPMs were sealed and then resealed during the study period. Although the study design lacked a control group for comparison, the lower caries rates of this study compared to the results of other studies with only a single application of sealants suggest a major role for resealing.
In Finland, the severity of road traffic injuries is determined using the International Classification of Diseases, 10th Revision, Finnish Modification (ICD-10-FM) injury codes from Finnish Hospital Discharge data and the automatic conversion tool (ICD-AIS map) developed by the Association for the Advancement of Automotive Medicine (AAAM). The aim of this study was to evaluate the ability of the ICD-AIS map to identify seriously injured patients due to traffic accidents in Finnish injury data by comparing the severity rating generated by an expert and by the ICD-AIS map.
Our data came from the North Kymi Hospital (level 2 trauma center at the time of the study). The data included 574 patients who were injured in traffic accidents during 2 years. The severity rating (Maximum Abbreviated Injury Scale [MAIS] 3+) of each patient was recorded retrospectively by an expert based on information from patient records. In addition, the rating was generated from ICD-10 injury codes by the ICD-AIS map conversion tool. These 2 ratings were compared by road user categories and the strength of agreement was described using Cohen's kappa.
The proportion of seriously injured patients was 10.1% as defined by the expert and 6.6% as generated by the ICD-AIS map; exact agreement was 65.5%. The highest concordance was for pedestrians (exact agreement 100%) and the weakest for moped drivers and motorcyclists (46.7%). Furthermore, the overall strength of agreement of the severity ratings (slightly or seriously injured) between the expert and the ICD-AIS map was good (??=?0.70). Most (65%) of the conversion problems were misclassifications caused by the simplicity of the Finnish ICD-10 injury codes compared to the injury codes used in the ICD-AIS map. In Finland, the injuries are recorded mainly with 4-digit codes and, infrequently, with 5-digit codes, whereas the ICD-AIS map defines up to 6-digit codes.
For this sample of simplified ICD-10-FM codes, the ICD-AIS map underestimated the number of seriously injured patients. The mapping result could be improved if at least open and closed fractures of extremities and visceral contusions and ruptures had separate codes. In addition, there were a few injury codes that should be considered for inclusion in the map.
The association between ABO blood groups and Achilles tendon (AT) ruptures was studied in 215 consecutive AT rupture patients treated at Oulu University Hospital during the 16-year period from 1979 to 1994 as compared with control material consisting of earlier blood group determinations performed on an unselected sample of 5,536 young Finnish male adults. There was no blood group O dominance or other statistical differences in ABO blood groups between the patients with AT rupture and the control population (chi 2 3.79, P = 0.28), the A/O ratio being 1.82 in the rupture group and 1.42 in the controls. We found no blood group O dominance in competitive athletes, recreational athletes or non-athletes, in patients with sports-related AT ruptures or non-sports-related ruptures and in younger ( or = 45--years) patients. In conclusion, our results do not confirm early findings of blood group O dominance in patients with AT rupture.
The human bocavirus (HBoV), a newly discovered parvovirus, is closely related to the bovine parvovirus and the canine minute virus, which are known to cause adverse pregnancy outcomes. Another human parvovirus, B19, can lead to fetal hydrops, miscarriage and intrauterine fetal death (IUFD).
To determine the prevalence of HBoV DNA in aborted fetuses and IUFDs. The HBoV serology of the mothers was also studied.
We retrospectively studied all available fetuses (N=535) autopsied during 7/1992-12/1995, and 1/2003-12/2005 in Helsinki, Finland. All available formalin-fixed paraffin-embedded fetal tissues - placenta, heart and liver - of 120 miscarriages, 169 IUFDs, and 246 induced abortions were studied by quantitative PCR. We also measured the HBoV IgM and IgG antibodies in the corresponding maternal sera (N=462) mostly of the first trimester. The IgM-positive sera underwent HBoV PCR.
None of the fetal tissues harbored HBoV DNA. A total of 97% (448/462) of the mothers were positive for IgG antibodies to HBoV, while only 0.9% (4/462) exhibited HBoV-specific IgM antibodies without viremia or respiratory symptoms. One IgM-positive mother had an unexplained fetal loss.
We did not find HBoV DNA in any of the deceased fetuses. Almost all pregnant women were HBoV-IgG positive.
The number of days of absence because of sickness, recorded for all children in one city in Finland, cared for in municipal day care over a period of 2.5 years, was collected from the monthly figures kept by the city council office for accounting purposes. The average number of days of absence per child was 24 per year at child-care centers and 9 in family care (p
There is scarce information in literature about the decisions made by ethics committees concerning the clinical studies they have reviewed. A retrospective, detailed review of 666 applications, their amendments and the ethics committees' statements was undertaken. All protrocols of clinical studies on medicinal products submitted to and reviewed by the ethics committees of two university hospitals during the years 1992, 1994, 1996 and 1998 were investigated. Most of the studies were international (50%), multicenter (71%), phase III trials (41%) on a new clinical entity, (38%). Validity of the clinical drug study applications was acceptable in more than half of the cases (364; 55%), while 91 (14%) were approved with advisory comments, 153 (23%) had to be amended, 35 (5%) were left pending and 23 (3%) were rejected. Most of the questions pertained to informed consent and the study protcol. In accordance with precious results, our findings support the opinion that the submitted documents need to be improved, especially with regard to informed consent and study protocols, in order to gain better Good Clinical Practice (GCP) compliance. Well-defined, documented operating procedures of the ethics committees would have facilitated the practical issues in the review process.
