[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.]

[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.]

[The authors studied the solubility of urate crystals in alcohol, in an 8% aqueous solution of formaldehyde and in acetone, respectively. The urate crystals were least soluble in alcohol. In comparison, the amount of urate crystals decreased in the aqueous solution of formaldehyde, which confirmed the suggestion of our predecessors that tissues suspected to contain urate crystals should be fixed in alcohol. Urate crystals dissolved in greatest amounts in acetone. Acetone is widely used by histological laboratories for dehydration of tissue blocks before embedding them in paraffin, which, in case of fixation in aqueous formaldehyde, contributes to the dissolution of urate crystals. In our earlier studies, we found that dissolution of urate crystals from haematoxylineosin stained sections is caused by the staining of nuclei in haematoxylin, therefore urate crystals are preferably demonstrated in unstained tissue sections.]

[In Hungary, the treatment approach for medial femoral neck fractures depends on the type of fracture and the overall condition of the patient. An obvious goal is to minimise the most common complications of the applied method, namely avascular necrosis of the head and redisplacement, while maintaining a low-risk and minimally invasive technique. Following the surgical method most commonly used in our country, we combined the double cannullated screws technique with the compressing HeadLess Screw System. This way we succeeded to achieve intraoperative compression, which provides intensified stability while retaining the principles of minimally invasive techniques.]

[MicroRNA molecules regulate the translation of mRNAs to proteins. In a study published by Maria A. Cortez and her colleagues in Nature in 2011, the authors suggest that miRNAs, known as biomarkers and translation regulators, could be considered as nucleic acid hormones. In this paper we introduce the characteristics of microRNAs that support their function as hormones.]
