[The physiological role of vitamin K in blood clotting and bone metabolism is well known. A number of articles have been published recently about the effects of vitamin K2 on bone. Non-professional media promotes vitamin K2 as a potent tool for the prevention and treatment of osteoporosis. Nevertheless vitamin K2 is not included in either Hungarian, or European, or Ameri - can guidelines as an anti-osteoporotic me - dication. Our aim was to review the literature and provide a systematic review on the role of vitamin K2 in the prevention and treatment of osteoporosis. We have searched articles on http://pubmed. org available on 14. February 2014. Our search terms were: („ vitamin K2” OR „ menaquinon” OR „ MK-7” OR „ menantrenon”) AND „ osteoporosis”. We have only reviewed original articles that discussed the relationship of vitamin K2 and osteoporosis, and had at least the abstract available in English. Of the 155 articles found, 135 had a relevant topic, 126 had at least the abstract in English. Of these, 73 were original articles, including 44 human studies (8 doubleblind, controlled, 26 open-label, controlled, 5 observational and 5 cross-sectional studies) and 29 animal or in vitro models. In the non-Asian population there is no evidence for fracture-preventing or BMD-increasing effect of vitamin K2 treatment. The currently recommended anti-osteoporotic medications are significantly more efficient compared with the BMD increase observed in some Asian studies.]

[MEET THE NEW MEMBER OF THE ALPRAZOLAM FAMILY]

FERENCZ Csaba

[The struggle against anxiety disorders and symptoms of anxiety is as old as the history of human healing. The development of anxiolytics has constituted an important field of pharmacology from the very beginning. The appearance of benzodiazepines and high-potential benzodiazepines, developed as a later evolution of the former compounds, is considered a milestone in this battle. Today alprazolam is their most widely-used representative that can be considered a golden standard. Besides its agent, the formulation of the drug is also significant, as it helps in the administration, absorption and bioavailability of the agent and even for the establishment of good compliance. Nowadays we can witness the development of medicine families containing the same active ingredient and consisting of various products. In the case of alprazolam, we can welcome a new member of the family following the immediate-release tablets and the extended-release tablets. The aim of this paper is the introduction of the new member of the alprazolam family: the sublingual tablet.]

[ORAL CARCINOMA AND ITS PREBLASTOMATOSES: THE ROLE OF PAPILLOMAVIRUS INFECTION AND THE PROSPECTS OF EARLY DIAGNOSIS]

DECSI Gábor, TARNAI Zsófia, ZSEDÉNYI Ádám, BUZÁS Krisztina, NAGY Katalin, SONKODI István, MINÁROVITS János

[The high incidence of oral carcinoma in Hungary is attributed primarily to tobacco and alcohol use. Recently, however, a series of publications suggested a role for humán papillomavirus in the development of oral carcinoma. For this reason we reviewed the literature regarding the associations of human papillomavirus with oral carcinoma and its preblastomatoses. We also overviewed research aiming to develop reliable methods for early diagnosis that are also suitable for screening. Early diagnosis and treatment may significantly improve the prospects of the patient. In addition, the addition of already available human papilloma virus vaccines into national vaccination programs and the extension of vaccination for both sexes may decrease the prevalence of oral carcinoma associated with human papillomavirus infection that primarily affects younger populations.]

[ANALYSIS OF THE KNOWLEDGE ON CERVICAL CANCER AND ATTENDANCE INDICATORS OF CERVICAL SCREENING]

VAJDA Réka, KARAMÁNNÉ Pakai Annamária, ÉLIÁS Zsuzsanna, SÉLLEYNÉ Gyuró Mónika, TAMÁS Péter, VÁRNAGY Ákos, KÍVÉS Zsuzsanna

[OBJECTIVE - The study aims to explore knowledge on cervical cancer and cervical screening among women with 9-14 yearold daughters, and learning the attitudes towards screening, the motivation of attendance at or absence from screening. DATA AND METHODS - A quantitative, cross-sectional study was conducted using our own questionnaire in the town Nagyatád in 2012. Study participants included women who had 9-14 year-old daughters and a registered home address in Nagyatád. We received valid responses from 186 people (response rate: 75.3%). RESULTS - The interviewed women’s knowledge on cervical cancer differed significantly depending on their age, education, marital status, and economic activity. Only 45 women with higher education (p=0.043) were considered to be well informed on the subject. However, their willingness to participate in cancer screening was more favorable than their knowledge, 96.2% of the women claimed to attend an annual cancer screening. The average age of respondents was 20.92 years at first visit. CONCLUSIONS - Although the participation rate was much higher compared with that in previously published studies, it is of great importance to increase the mothers’ knowledge on cervical cancer and the factors that promote its development, so that they can pass their knowledge to their children and strengthen their protection against one of the most common sexually transmitted viral infection and the development of cervical cancer.]

[Evaluation of quality of life following treatment with calcitonin nasal spray in patients with osteoporosis: preliminary results of the MERLIN study]

BORS Katalin, KÓSA József, BORBÉLY Judit, TABÁK Ádám, HORVÁTH CSABA

[INTRODUCTION - MERLIN (Management of Osteoporosis in Elderly with Calcitonin) is an open-label, multicenter, prospective, follow-up study conducted in Hungary, part of which is to assess the impact of treatment with Miacalcic, - an intranasal salmon calcitonin, on the quality of life (QoL) among patients with osteoporosis. In this paper we report the preliminary results of the MERLIN study. PATIENTS - The study initially involved 1949 senior patients (aged >65 years) to whom calcitonin was prescribed for osteoporosis according to the application instructions. Patients presented at outpatient clinics and consisted of two groups; they were either newly diagnosed or they had been receiving a therapy for osteoporosis other than calcitonin. METHODS - This latter group discontinued their previous treatment and all patients received 200 IU intranasal salmon calcitonin (SCT) once daily for three months. Patient and physician questionnaires were used to collect information on the patients' QoL (EQ-5D VAS) and their general well-being at baseline and at follow-up visits at week 4 and week 12. RESULTS - Calcitonin use was associated with improvements in all EQ-5D domains and component scores as well as in VAS. Patients with previously known osteoporosis who, switched to calcitonin therapy achieved better results (0,046 QALY), than the newly diagnosed patients (0,0405 QALY). CONCLUSIONS - We conclude that intranasal SCT 200 IU daily is safe and effective in improving QoL of both, male and female patients with low bone mineral density.The conclusions that can be drawn from this study are limited due to the lack of a control group and to the unblinded design. Further placebo-controlled studies are needed to confirm these results. Nevertheless, our study was the first in Hungary to evaluate the quality of life impact of an osteoporosis treatment, and hopefully it will be followed by more such studies directed to other osteoporosis treatments.]

[Bone metabolism and body mass index in postmenopausal women]

TÁRCZY Csaba, TOLDY Erzsébet, SZERB János, VARGA László

[INTRODUCTION - In addition to several other causes constitutional factors play an important role in the development of osteoporosis.Various aspects of bone metabolism were examined to explain the differences in bone density between women with low and high body mass index (BMI). PATIENTS AND METHOD - One hundred and ninetytwo postmenopausal women were included in the study. Bone density was measured by forearm densitometry.To assess bone formation, serum osteocalcin levels were measured, while the rate of bone absorption was estimated from C-terminal telopeptide levels of collagen type I measured in urine and blood. RESULTS - The prevalence of osteoporosis was higher in women with low BMI than in those with normal or higher BMI. Bone metabolism - both formation and absorption - was increased in both groups, however, in women with low BMI this increase was more pronounced and bone metabolism tended to be shifted to absorption compared to patients with normal or higher BMI. CONCLUSION - Postmenopausal lean women have accelerated bone metabolism compared to obese women. This fact and the shift to absorption may be the main reasons for the higher frequency of osteoporosis found by densitometry in women with low BMI than in those with higher BMI.]

[Bone mineral density and diabetes mellitus - First results]

TÕKE Judit, TAMÁS GYULA, STELLA Péter, NAGY Erzsébet, NÁDASDI Ágnes, VARGA Piroska, KERÉNYI ZSUZSA

[INTRODUCTION - Data on bone mineral density (BMD) in diabetes mellitus are contradictory in the literature. Early studies described a decreased bone mineral density in type 1 diabetes mellitus (T1DM), but recent studies report no osteopenia in T1DM.The BMD may depend on the quality of treatment for diabetes mellitus and on the presence of chronic complications. In type 2 diabetes mellitus (T2DM) the BMD is not decreased, occasionally it can even be increased. PATIENTS AND METHODS - Bone mineral density was measured in 122 regularly controlled diabetic patients (T1DM: n=73, mean age: 43.6±11.1 years,T2DM: n=49, mean age: 61.8±9.8 years) by dual energy X-ray absorptiometry at the lumbar spine and at the femur. Results were compared to those of 40 metabolically healthy control persons with a mean age of 47.5±11.9 years.The patients’ carbohydrate metabolism was assessed by the average HbA1c level of the last three years.These values were 7.9±1.4 % in T1DM, and 7.5±1.7 % in T2DM. BMDs were classified based on the T-score and Z-score using the WHO criteria. RESULTS - There was no significant difference in T1DM or in T2DM compared to the reference group in the prevalence of either osteoporosis or of osteoporosis and osteopenia combined. CONCLUSION - BMD was not found to be decreased in patients with well-controlled metabolism compared to healthy controls.]

[We conducted a multicentre, prospective, single cross-sectional, 12-month, open-label study for the assessment of treatment satisfaction using TSQM (Treatment Satisfaction Questionnaire for Medication) for zoledronic acid therapy used in patients with osteoporosis, who suffered minor traumatic fractures. PATIENTS AND METHODS - In total 1736 patients from 94 centers completed the study and filled in the TSQM questionnaire at both visit 1 and visit 2. TSQM is suitable for measuring the patient’s satisfaction with a treatment, by evaluating side-effects, efficacy and convenience of the treatment and the patient’s overall satisfaction rated on a scale of 0 to 100. RESULTS - Patients included in the study previously received a mean of 1.58 other therapies for osteoporosis and their case history included a mean of 1.24 fractures. This real-life study demonstrated that even one year of zoledronate treatment significantly (p<0.0001) improved the satisfaction of patients regarding efficacy (a mean change from a score of 56.15 to 70.89) as well as the occurrence of side-effects on a TSQM score. Regarding the convenience of treatment, the mean score increased from 62.96 to 79.34 (p<0.0001), whereas the overall treatment satisfaction changed from 59.3 to 75.48 by visit 2 (p<0.0001). CONCLUSIONS - Our study demonstrated beneficial TSQM results associated with zoledronic acid treatment, which is a basic requirement for appropriate adherence as well. ]

[Once again on adherence - Is it just fashionable or indeed a timely issue?]

VALKUSZ Zsuzsanna

[Nonadherence to pharmacological treat-ment in osteoporosis is a well-recognised problem not only in Hungary but all over the world. As in other chronic diseases, adherence to osteoporosis treatment is poor, which results in serious problems affecting patients as well as health care resources. Low adherence rates consistent-ly result in increased rates of fractures. Some approaches aimed to improve com-plience and persistence, such as extension of dosing intervals, might improve patients’ adherence to therapy. International clinical studies have demonstrated that the number of fractures cannot be reduced without suf-ficient adherence. Improving patient edu-cation, enhancing interactions between health care providers and patients, taking into account patients’ preferences and involving them in treatment decisions may all improve adherence.]
