The history of ideas of Nordic midwives’ excursions from the early 19th century to the millennium

The midwifery art has emphasised the uniqueness of human beings throughout its Nordic history. The educated Nordic midwife has in the last decade celebrated several hundred years of memories. This article studies how the key ideas of the midwifery art and patterns of ideas become evident in the zeitgeist from the beginning of the 19th century to the millennium in the Nordic countries. The legacy and pattern of ideas of the art of midwifery are interpreted in relation to the texts of the selected historical sources and based on Ricoeur's phenomenological-hermeneutic approach to the text and further to the dedication of understanding and interpretation. The historical sources refer to unprinted primary sources from historical archives and printed secondary and tertiary sources. The patterns of ideas include a tripartite whole: the true cultivation of the head, the philosophy and aesthetics of the hand, the strength of the heart and the drive of calling. These ideas open for unique visions and attest to the evident in modern midwives. Today's midwives have academic training with examinations, and the education is based on scientific evidence. The midwife profession is authorised by the state and supervised by the authorities.     

Adverse events due to unnecessary radiation exposure in medical imaging reported in Finland

IntroductionAdverse events in radiology are quite rare, but they do occur. Radiation safety regulations and the law obligate organizations to report certain adverse events, harm and near misses, especially events related to patients' health and safety. The aim of this study was to describe and analyse incidents related to radiation safety issues reported in Finland.MethodsThe data were collected from incident reports documented by radiology personnel concerning notifications of abnormal events in medical imaging made to the Radiation and Nuclear Safety Authority between 2010 and 2017. During these eight years, 312 reports were submitted. Only events reported from radiology departments were included; nuclear medicine, radiotherapy and animal radiology cases were excluded. The final number of reports was 293 (94%).ResultsThe majority of the 293 approved reports were related to computed tomography (CT, 68.3%) and to X-ray examinations (27.6%). Altogether 82.9% of those irradiated were adults, most of whom were exposed to unnecessary radiation through CT (86.5%), 5.5% were children, and 4.4% pregnant women. The most common effective dose of unnecessary radiation was 1 mSv or less (89.7% of all examinations). The highest effective doses were reported in CT (from under 1 mSv–20 mSv and above). The reasons for the adverse events were incorrect identification (32%), incorrect procedure, site or side (30%); and human errors or errors of knowledge (20%).ConclusionAdverse events occurred especially in CT examinations. It is important to collect and analyse incident data, assess the harmful events, learn from them and aim to reduce adverse events.Implications for practiceThis study emphasizes the need for radiological personnel to obtain evidence-based information on adverse events and focus on training to improve patient safety.     

Plasminogen activator is involved in the hCG-induced neutrophil extravasation and vasopermeability increase in the rat testis

The role of proteolytic enzymes in the hCG-induced increase in testicular vasopermeability and neutrophil extravasation was studied using protease inhibitors. An intra-testicular injection of hCG together with incubation medium conditioned by polymorphonuclear leucocytes (PMNs) caused a significant increase in vasopermeability and a coincident extravasation of PMN's from the postcapillary venules in the rat testis. When p-aminobenzamidine, a serine protease inhibitor which inhibits urokinase-type plasminogen activator, was administered together with hCG in the incubation medium, both the permeability increase and PMN extravasation were prevented. Aprotinin, another serine protease inhibitor, and Eglin C, a specific neutrophil elastase and cathepsin G inhibitor were, however, without effect. None of these inhibitors caused any non-specific vascular effects in the testis at the concentrations used. These results support the concept that the hCG-induced increase in vasopermeability in the rat testis is related to extravasation of PMNs and suggest that urokinase-type plasminogen activator is involved in migration of these cells through the postcapillary venular walls.     

Teaching sociology of medicine: the group process

As a part of any curriculum reorganization, new instructional methods are also tested. When the University of Turku sociology of medicine course was found to need renovation, its goals and objectives, content and instructional methods were closely examined and modified, in order to strengthen institutional and multiprofessional relations and reinforce sociocultural issues in doctors' competence with the patient. This paper discusses this change, emphasizing teaching and learning methodology.     

An outbreak of trichinellosis in farmed wild boar in Finland

Nine farmed wild boar out of 25 slaughtered from a single farm were condemned at meat inspection because of trichinellosis. With RAPD-PCR, Trichinella spiralis was identified in all positive wild boar. Out of the available serum samples (n=7), all wild boar which had failed the meat inspection showed seroconversion in ELISA and Western blotting, as did one additional animal which had passed the inspection. The animals became infected during an invasion of rats from an improperly closed dump near the farm. Unfortunately, by the time trichinellosis was discovered in the wild boar, the invasion had already been brought under control; thus, no samples from rats were available. However, having lived through the rat invasion was shown to be a risk factor for trichinellosis in wild boar (relative risk, RR=6.3). In wildlife samples from surrounding areas, sylvatic trichinellosis was found to be very common (74%; n= 19 red foxes). Intriguingly, the prevalent species in trichinella-positive foxes differed from that in wild boar, Trichinella nativa and T. spiralis being found in 12 foxes and in one fox, respectively.     

Cancer incidence among Finnish seafarers, 1967–92

A cohort of 30,940 male and 11,529 female seafarers registered in the files of Seafarers' Pension Fund in Finland was followed up through the Finnish Cancer Registry for cancer in 1967–92. Among male seafarers, there were 1,199 cases of cancer, which corresponds to the average cancer incidence in Finnish men. There was a statistically significant excess of non-melanoma skin cancer (standardized incidence ratio [SIR]=1.8, 95 percent confidence interval [CI]=1.2–2.5) and mesothelioma (SIR=2.9, CI=1.2–5.6) in the follow-up category of 20 or more years since the first employment. Alcohol-related cancers were increased among seafarers (SIR for cancer of the mouth and pharynx = 1.; esophagus = 1.4; and liver = 1.5; combined CI=1.1–1.9). Deck crews had a significantly high risk of cancer of the pancreas (SIR=2.0) and also prostate after 10 years since first employment (SIR=1.6). Occupational asbestos exposure among seafarers is likely strong enough to cause excess cases of mesothelioma but not of lung cancer. Occupational exposures also may be associated with increased risk of cancers of the kidney, pancreas, prostate and old-age brain cancer in some of the main occupational categories. Cumulative ultraviolet radiation likely doubles the risk of nonmelanoma skin cancer among older men and repeated sunburns that of skin melanoma in ages below 30 (SIR among deck and engine crew = 4.6, CI=3.1–6.5). Female ship personnel had a significantly elevated total cancer risk (observed number of cases = 732) which increased over follow-up time (SIR in the category 20 years since the first employment was 1.3, CI=1.1–1.5). This excess was attributable primarily to lung cancer (SIR=2.6, CI=2.0–3.3). Also cancers of the cervix uteri, vulva, and vagina showed significant excess after 10 to 20 years since first employment aboard.Address correspondence to Dr Pukkala, Finnish Cancer Registry, Litsankatu 21 B, FIN-00170 Helsinki, Finland.

Serum levels of vitamin D metabolites and the subsequent risk of colon and rectal cancer in Finnish men

Experimental and human epidemiologic data suggest a protective rolefor vitamin D in large bowel cancer. To investigate this association, weconducted a nested case-control study within a Finnish clinical trial cohort.Cases (n = 146) were participants diagnosed with primary adenocarcinoma ofthe large bowel. Controls were matched (2:1) to cases on age, date ofbaseline blood draw, and study clinic. Prediagnostic serum levels of thevitamin D metabolites, 25-hydroxyvitamin D (25-OH D), and1,25-dihydroxyvitamin D (1,25-DIOHD) were used as primary exposure measures.The baseline geometric-mean serum level of 25-OH D was 11.6 percent lower incases than in controls (12.2 cf 13.8 ug/l, P = 0.01) while serum levels of1,25-DIOH D did not differ by case-control status. No association was seenbetween serum levels of 1,25-DIOH D and large bowel cancer risk. However, theestimated relative risk (RR) of large bowel cancer decreased with increasinglevel of serum 25-OH D and the associa tion was more pronounced for rectalcancer (55 cases; RR by quartile = 1.00, 0.93, 0.77, 0.37; trend P = 0.06).Neither exclusion of early cases nor multivariate adjustment for potentialconfounders materially altered these estimates. There was no evidence ofeffect modification by level of 1,25-dihydroxyvitamin D or with other knownrisk-factors for large bowel cancer.     

Potential case of gynecomastia in mummified remains of an early modern period northern finnish vicar

We report possibly the oldest evidence of gynecomastia in mummified human remains. Computed tomography was performed on the mummified remains of an early 17th century Northern Finnish vicar. The examination of the scans revealed large bilateral subareolar irregular masses resembling female mammary glands. The nearly septuagenarian vicar appears to have had gynecomastia, as it is a common condition in elderly men, and is sometimes associated with obesity. Gynecomastia is the most likely explanation for these findings. Clin. Anat. 31:641–644, 2018. © 2018 Wiley Periodicals, Inc.
