Fatigue fractures in military conscripts : A study on risk factors, diagnostics and long-term consequences Ruohola, Juha-Petri University of Helsinki, Faculty of Medicine, Institute of Clinical Medicine, Orthopaedics and Traumatology, Helsinki University Central Hospital Centre of Military Medicine, Helsinki 2007-03-09 Doctoral dissertation (article-based) It seems likely that low vitamin D levels are related to fatigue fractures, and that an increasing trend exists between TRACP-5b bone resorption marker elevation and fatigue fracture incidence. Though seldom detected by plain radiography, fatigue fractures often underlie unclear lower leg stress-related pain occurring in the distal parts of the tibia. Femoral neck fatigue fractures, when displaced, lead to long-term morbidity in a high percentage of patients, whereas, when non-displaced, they do not predispose patients to subsequent adverse complications. Importantly, an educational intervention can diminish the incidence of fracture displacement by enhancing awareness and providing instructions for earlier diagnosis of fatigue fractures

Defining Adequate Vitamin D Intake : Cross-sectional and Intervention Studies Viljakainen, Heli Tuulikki University of Helsinki 2008-05-23 Doctoral dissertation (article-based) Vitamin D is required for normal bone growth and maintenance of the skeleton throughout life. In Finland, like in many other Western countries, the population suffers from inadequate or deficient vitamin D status, especially during winter, which is thought to increase the risk of osteoporosis. New strategies to prevent osteoporosis are actively being sought. The main objective of this thesis was to determine whether vitamin D is feasible in the primary prevention of osteoporosis; does it affect bone mineral accrual during the growth period? A second goal was to ascertain whether seasonal variation in calcitropic hormones affects bone remodelling, and to elucidate the vitamin D intake needed to overcome this variation in different age groups. In summary, vitamin D intake remains inadequate among the target groups of this thesis, as reflected by seasonal variation in calcitropic hormones and bone metabolism. Dietary intake of vitamin D should be increased to achieve at least an adequate vitamin D status (S-25-OHD>50 nmol/l) and possibly an optimal vitamin D status (S-25-OHD>80 nmol/l) throughout the year. This could be accomplished by introducing new vitamin D-fortified foods to the market."

Bio-immunotherapy in the treatment of equine sarcoid, the commonest tumour of the horse Research Article Raija E. Hallamaa Veterinary Clinic, Pisteenkaari 4, 03100 Nummela Institute of Bio-Immunotherapy, Gylden Str. 2B, 00200 Helsinki, Finland

"NEW YORK (Reuters Health) - Low vitamin D levels in the body may be deadly, according to a new study hinting that adults with lower, versus higher, blood levels of vitamin D may be more likely to die from heart disease or stroke. Vitamin D is an essential vitamin mostly obtained from direct sunlight exposure, but also found in foods and multivitamins. Dr. Annamari Kilkkinen, at the National Institute for Health and Welfare in Helsinki, Finland, and colleagues compared blood levels of vitamin D and deaths from heart disease or stroke over time in 2,817 men and 3,402 women in Finland."
