[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.]

[About vitamin D - let’s combine!]


[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.]


[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.]


[Our predecessors were right - Closing remarks on the solubility of urate crystals in microscopic specimens]

BÉLY Miklós, KRUTSAY Miklós

[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.]


[Femoral neck fractures treated with DHLS screws - early results]

KOCSIS András, KÁDAS István, KÁDAS Dániel, HANGODY László

[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.]


[Quality of life of patients with osteoporosis in Hungary]

VOKÓ Zoltán, INOTAI András, HORVÁTH CSABA, BORS Katalin, SPEER Gábor, KALÓ Zoltán

[AIM - The aim of our study was to estimate the loss of quality of life due to osteoporotic fractures. We performed a cross-sectional study including 840 patients in 21 centers that specialise in the care of patients with osteoporosis and in acute care of fractures. METHODS - Patients were selected randomly and stratified for the location of and time elapsed since the fracture. Quality of life (QoL) was assessed by the Qualeffo-41 and the EuroQol-5D questionnaires. RESULTS - Patients with morphometric fractures of more than one vertebra had the lowest median EQ-5D index value (0.59). Symptomatic vertebral, hip and arm fractures also considerably decreased QoL. Patients with morphometric fractures of more than one vertebra had the lowest total Qualeffo-41 score. When controlled for age and gender, patients with hip fracture or morphometric vertebral fracture had at least 0.2 less mean utility values than had osteoporotic patients without history of fracture. Patients with more than a oneyear history of hip fracture had QoL scores as low as had patients with an acute fracture. In case of wrist and arm fractures, the acute loss of QoL somewhat decreased with time. CONCLUSION - In conclusion, osteoporotic fractures, especially hip and vertebral fractures result in a significant loss of patients’ quality of life. Our results show that physicians need to pay a close attention to morphometric vertebral fractures, which contribute to a great loss of human capital.]

[Obesity and cancer]


[The role of obesity in the development of cancer is well-known from ages. However, these days we witness the explosion-like increase of obesity, globally, but mainly in the economically advanced population, and, which is even more alarming, among youngsters. The prognosis of the obesity-related cancer is rather poor, therefore, the prevention, including the screening, have outstanding importance. Unfortunately, the participation of the obes persons, especially obes women, in these programs is very low. The diagnostics and therapies should consider the special features of obesity, which are related to the magnitude, distribution, composition of fatty tissue connected to the changes in pharmacokinetics. Moreover, the problems might be complicated with obesity-associated non-tumorous severe diseases (e.g. cardiovascular, diabetes type 2).This review covers different aspects of obesity-cancer relationships, with an emphasis on everyday oncology.]

[Pregnancy and cancer]

NAGY Zsuzsanna, SZILLER István, VALTINYI Dorottya, HORVÁTH Orsolya

[The joint appearance of pregnancy and cancer is rare. It is highly recommended that the tumorous pregnant should be managed by a multidisciplinary team. The early diagnosis is very important, but it is not easy, because the symptoms of pregnancy and cancer are rather similar. Imaging diagnosis has to avoid ionizing radiation (e.g. PET/CT). The same is true for chemotherapy in the fi rst trimester, due to the increased risk of developmental abnormalities. Consequently, radiation therapy is not allowded throughout the pregnancy, and the chemotherapy in the fi rst trimester is a strong indication for the interruption of pregnancy. Surgery, with good practice, usually can be performed without complications. Chemotherapy, given in the second and third trimester generally follows the standard protocols with a low frequency of developmental errors. Early delivery should not be encouraged, except the delay has a hazardous effect on the mother and/or on the child. The pregnant should be informed about all steps to be an active part of the fi nal decision.]

[Paleo-oncology - messages from the past]

MOLNÁR Erika, MARCSIK Antónia, PÁLFI György, ZÁDORI Péter, BUCZKÓ Krisztina, TAKÁCS Vellainé Krisztina, HAJDU Tamás

[Nowadays, cancer is one of the greatest challenges facing mankind. However, there is still no consensus among researchers regarding the antiquity of cancer. Written sources and paleo-oncological studies may help to answer this question. The aim of this study is to present data on the history of cancer based on historical sources, literature data and own research fi ndings. Early historical sources indicate that cancer was already known in antiquity. Paleopathological studies of animal and human fossils show that malignant bone tumors were present in ancient times, although the frequency of the disease was seemingly very low. The increasing number of unearthed fossils and the use of modern diagnostic tools have led to a rise of the number of diagnosed cancer cases. Our comprehensive paleo-oncological study, focusing on the occurrence and frequency change of malignant tumors in historic populations of Hungary was based on the analysis of skeletal remains belonging to 11,000 individuals dated from the Early Neolithic to the late medieval period. During the analysis macromorphological, modern imaging and histological methods were applied. As a result of the extensive investigations osteological evidences of malignant bone tumors were identifi ed in 39 cases. Neoplastic bone diseases were present in all studied historical periods and there were no differences in their occurrence and frequency between the different archaeological periods.]

[Clinical role of multigenic prognostic tests in breast cancer therapy]


[Current clinical practice for breast cancer originates in “evidence based medicine”. In this, each tumor receives a therapy optimal for a given patient population - which might not be optimal for each individual patient. Multigenic tests determining expression of a set of genes can provide additional support in this decision process. Two such tests (MammaPrint and Prosigna) have already received FDA clearance. A number of additional test are commercially available (IHC4, Oncotype DX, EndoPredict, BCI). A common property of these assays is their utility in estrogen receptor positive early breast cancer. The main clinical problem answered by them is the necessity of adjuvant chemotherapy. To date, no reliable algorithm has been identifi ed capable to pinpoint the most effective chemotherapy combination for a given patient. Furthermore, there is no trustworthy test for triple negative breast cancer. The assays utilize different technologies (immunohistochemistry, gene chips, RT-PCR) and a discrepant list of genes - these result in discordance of the predictions for the individual patient. Despite these shortcomings, multigenic tests quickly gained foothold in breast cancer therapy decision process. Their utility is supported by the cost reduction for the health care providers by lowering the number of patients eligible for chemotherapy.]

Purpose - In cancer patients, an ischemic stroke can be seen as both a direct effect of cancer and a complication of treatment. This condition can negatively affect the follow-up and treatment of these patients. For this research, we aimed to evaluate the clinical features, stroke types and etiological features of ischemic stroke patients with histories of cancer or found to have cancer during the aetiological investigation. Materials and methods - We retrospectively evaluated 100 patients (57 males, 43 females) who were hospitalized with acute stroke and determined to have the presence of cancer or a cancer history during the aetiological investigation between 2011 and 2016. All the demographic features, stroke types and localizations, National Institutes of Health Stroke Scale (NIHSS) scores, Rankin Scale scores, durations of cancer and cancer treatments were recorded. Results - The mean age of the patients was 67.07 ± 10.9 years old, the median NIHSS score was 5, and the median Rankin Scale score was 4. While 79% of patients had ischemic stroke risk factors, 21% did not. Atherosclerotic stroke was the most common stroke type (49%, n=49) and cryptogenic strokes were detected in 21% (n=21). In addition, 63% of the patients had chronic cancer (later than 6 months), 31% of the patients had recent cancer histories (less than 6 months), and 29% of the patients had metastases. Among all the malignancies, lung cancer (n=23), gastrointestinal cancer (n=20) and gynaecological-breast cancer (n=16) were the three most common. Moreover, 37% of the patients underwent chemotherapy, 29% underwent radiotherapy, and 88% of the patients had Carotid/Vertebral Doppler USG abnormalities. Conclusion - Similar to what is stated in the literature, an atherosclerotic stroke was the most common type of stroke in the cancer patients. Stroke risk factors were not detected in 21% of the patients, and in the majority of the patients, atherosclerotic changes in the carotid artery were observed in the Doppler examinations. In the aetiology and prognosis of ischemic stroke, it is important to keep in mind the existence of cancer in addition to the classical stroke risk factors.
