[Vitamin D plays an important role in several pathways in humans. Its relation with several diseases has been previously de­scribed. Vitamin D deficiency affects al­most the full population on temperate zone at the end of the winter. Recommendations on vitamin D supplementation are inconsistent and there are only a few data about the efficacy of cholecalcipherol given not in daily manner. In the present paper, we examine the different administration mo­dalities, and their efficacy in increasing serum vitamin D levels. High doses administered rarely appear to be equally efficient and safe compared to low doses provided frequently.]

[Objectives: Was to evaluate 10-year probability of hip fracture and a major osteoporotic fracture using the FRAX algorithm, vitamin D status, bone mineral density (BMD) and biochemical markers of bone turnover in men over 50 years of age with type 2 diabetes (T2DM). We compared FRAX-predicted 10-year fracture probability, levels of 25-hydroxyvitamin D (25-OH-D), markers of bone turnover and bone mineral density at L1-L4 (LS) and femur neck (FN) in 68 men with T2DM with an age- and gender-matched group (n=68). The mean (range) age of the T2DM group was 61.4 (51-78) years. The prevalence of hypovitaminosis D (25-OH-D <75 nmol/L) was 59%. The mean (range) FRAX hip fracture and FRAX major osteoporotic fracture was 0.7 (0-2.8)% and 3.2 (0-8.5)%, respectively. BMD at the FN (0.974 gm/cm2 vs. 0.915 gm/cm2; p = 0.008) and LS (1.221 gm/cm2 vs. 1.068 gm/cm2; p < 0.001) was significantly higher in the T2DM cohort as compared to the healthy age matched males. 25-OH-vitamin D (67.7 nmol/L vs.79.8 nmol/L; p < 0.001), crosslaps (0.19 μg/L vs. 0.24 μg/L; p = 0.004) and osteocalcin (13.3 μg/L vs. 15.7 μg/L; p = 0.004) were significantly lower in the T2DM group. There was no difference in FRAX-related fracture probability between the two groups. The increased BMD in T2DM and the lack of inclusion of T2DM as a risk factor in the FRAX algorithm are probable explanations for the discordance between literature-observed and FRAX-related fracture probabilities.]

[Experiences from the dissection room. Quantitative and qualitative study among Hungarian medical students]

IMOLA Sándor, CSALA Irén, BIRKÁS Emma, GYŐRFFY Zsuzsa

[BACKGROUND - The anatomy and pathology are the most outstanding field of the medical curriculum. These subjects mean the first practical experiences of dissection. The international literatures results shows that experience of dissection are important stages of becoming physician, but not always problemless. METHODS - Quantative (n=733) and qualitative (n=45) exploratory research among Hungarian medical students. We tried to present the effects and experiences of dissection pratcise using both analytical methods. Validity of the research was greatly improved by using the two methods. RESULTS - 50% of medical students reported that they were affected by dissection practice. The female students and those in clinical training (III-VI.years) reported about negative effects significantly more frequently. The results of the qualitative survey verified that dissection practices have decisive effect during the training and coping with experiences was often difficult especially for females students. CONCLUSIONS - Our research confirmed the hypothesis of dissection experiences play outstanding role in becoming physician. The successful coping isn’t the repression or ignorance of emotion, but understanding and finding effective solutions strategies for the negative emotions of experiences. Managing these experiences are a crucial factor of latter wellbeing of physicians and decisive factor of doctors-patient relationship.]

Correlation of vitamin D levels with electrophysiological findings and pain in the patients with Carpal Tunnel Syndrome

DEMIRYÜREK Enes Bekir, SENTÜRK Asli

Objective - This study aimed to assess the correlation between vitamin D deficiency and electrophysiological findings and pain level in patients with symptoms of carpal tunnel syndrome (CTS). Patients and method - A total of 131 patients with symptoms of CTS, 70 with vitamin D deficiency and 61 without vitamin D deficiency, were included in the study. Using demographic data and findings from electrophysiological examinations, the patients were divided into two groups based on their vitamin D level (Group 1: <20 ng/ml; Group 2: ≥20 ng/ml). The Boston Carpal Tunnel Syndrome Questionnaire was used to assess their CTS- related pain level. Results - Although the rate of CTS in the patients with a low vitamin D level was found to be high, no statistically significant correlation was observed between low vitamin D level and the frequency and severity of CTS. Additionally, the pain and functional loss ratio induced by CTS was found to be higher in the group with a lower vitamin D level than in the group with normal levels. Conclusion - Low vitamin D levels may increase the severity of CTS symptoms. Treatment of vitamin D deficiency in patients with CTS can play a role in reducing pain and disability.

[Serum 25(OH)-Vitamin D levels and bone metabolism in patients on maintenance hemodialysis]

ALMÁSI Csilla és munkatársai

[INTRODUCTION - Increasing evidence suggests that 25- hydroxy vitamin D3 (25(OH)D3) may contribute to the bone health of patients with chronic kidney disease.However, there is very little information available on the vitamin D3 status of patients with chronic renal failure. In a cross-sectional study we assessed the association between vitamin D3 status and parathyroid function, bone turnover, bone mass and structure in patients on maintenance haemodialysis. PATIENTS AND METHODS - Sixty-nine patients on maintenance haemodialysis were assessed by bone densitometry (DEXA) and quantitative bone ultrasound. Serum 25-hydroxy vitamin D3 levels and serum markers of bone turnover were simultaneously measured. RESULTS - A high prevalence of potentially significant vitamin D3 deficiency was found in this patient group; 59% of the patients had their 25(OH)D3 vitamin level below 20 nmol/l.There was a significant negative correlation between serum 25(OH)D3 and serum intact parathormone (iPTH) levels (r=-0.231, p<0.05) and this association remained significant after controlling for potential co-variables. Furthermore, a positive correlation was observed between serum 25(OH)D3 concentration and bone mineral density measured at the radius (r=0.424, p<0.01). Finally,we show for the first time that 25(OH)D3 levels are significantly and independently associated with broad band ultrasound attenuation (β =0.237, p<0.05) measured with calcaneal quantitative bone ultrasound in patients with chronic renal failure. CONCLUSION - Vitamin D3 deficiency may contribute to the impaired bone health of patients on maintenance dialysis, therefore, it seems to be warranted regularly monitoring and carefully controlling the D3-vitamin level of these patients.The results also suggest that quantitative bone ultrasound is useful in assessing bone health of patients with chronic renal failure.]

[The importance of vitamin D deficiency in practice]

TAKÁCS István

[The effects of vitamin D in bone health have been known since the 1920s. Recently, it has been proven that its role in the body is much more complex. Activated vitamin D is a steroid hormone that regulates transcription of more than 200 human genes through its receptor that is detectable in almost all types of cells. In contrast to the former conceptions, it can be activated not only in the kidneys; moreover, local 1-α-hydroxylation plays a greater role in its extraskeletal effects. Vitamin D deficiency, currently defined as serum levels of <30 ng/ml, is caused by the lack of ‘effective’ sunlight exposition. Thus, vitamin D deficiency is one of the most frequent deficiencies in the developed world that plays a role not only in the development of skeletal conditions but many other diseases, as well. A low vitamin D level causes a reduced calcium absorption, a higher bone remodelling rate and increased bone loss. It also reduces muscle strength and increases the risk of falling. Normal vitamin D status is required for the effectiveness of drugs for osteoporosis treatment; however vitamin D treatment in itself is not effective in osteoporosis. An increasing number of studies show the benefits of vitamin D supplementation and treatment in extraskeletal conditions. Vitamin D plays an important role in the prevention of several auto-immune diseases, infections, cardiovascular diseases, and cancers. Therefore, all UV-B radiation-deprived adults require an intake of vitamin D to maintain a level of >30 ng/ml. Vitamin D3 treatment is safe. The necessary dose can be reliably approximated by the calculation that an incremental consumption of 100 IU/day raises serum vitamin levels by 1,0 ng/ml. Clinical trials suggest that for the vast majority of individuals, a prolonged intake of 10,000 IU/day does not pose any risk.]

[Vitamin D deficiency is a worldwide health problem. On the basis of the recommendations of the latest vitamin D consensus conference, we would like to draw attention to the significance of prevention as well as the recognition and treatment of vitamin D deficiency. We mention that some antiporotics designated “prefix” or “combi” are available that may ensure adequate calcium and vitamin D intake, thus improving patient’s adherence.]

[EFFECTS OF VITAMIN D AND THE EFFICACY OF VARIOUS VITAMIN D PRODUCTS]

BORS Katalin

[An increasing number of studies suggests that the effects of vitamin D is not limited to the regulation of calcium homeostasis, but it is also involved in several other physiologic processes. Vitamin D receptors are present on the surface and in the nucleus of most cells. Vitamin D as a steroid hormone has genomic and non-genomic effects. Vitamin D deficiency is an important problem worldwide, and so is in Hungary. Vitamin D promotes bone formation and mineralization and decreases the rate of bone absorption. Its extraskeletal effects include antitumour, muscle strength increasing, antiinflammatory, blood pressure lowering and insulin secretion increasing activites.]
