[Pain relief in metastatic bone disease]

BOÉR Katalin

[Metastatic bone disease is a hallmark of distant relapse of a number of solid tumours. The treatment of bone metastases is palliative, the main goal is to relieve pain, whereas it’s also important to reduce the risk of bone fractures, prolong survival and maintain the physical activity of patients. Pain is one of the most common symptoms of bone metastases, and state-of-the-art pain relief has an important role in maintaining the patients’ quality of life. Therapies to control pain include drug therapy, radiotherapy, surgery, systemic oncotherapy, such as chemotherapy and/or hormone therapy, multibone radioisotope therapy and administration of bisphosphonates. Regarding the relief of pain caused by malignant tumours, the guidelines developed by the World Health Organization should be followed. The algorithm of pain relief starts with assessment of the pain’s intensity and includes both pharmacological and nonpharmacological interventions. Analgesics used for pain relief include nonopioids, opioids and adjuvant agents. The pain can be efficiently relieved with the combined use of modern analgesics in the great majority of patients.]

[Pain management in rheumatology]

NAGY Katalin

[Pain is the most common symptom in rheumatology, which can be of mechanical or inflammatory origin, acute and chronic, nociceptive, neuropathic and psychogenic. Pain can be relieved by analgesics, nonsteroidal anti-inflammatory drugs, opioids, adjuvants and special drugs depending on the etiology, for example a gout attack can be stopped by colchicine. For pain relief, we use therapeutic guidelines of the World Health Organization (WHO), which recommends the use of analgesics, NSAIDs and adjuvants as the first step, weaker opioids as the second, and strong opioids as the third step. In rheumatology, the first step's drugs are generally used. If possible, NSAIDs should be administered briefly, potentially combined with analgesics and muscle relaxants. If pain management is insufficient, tramadol should be given. Pain relief in rheumatology also include the use of local and intraarticular injections, physiotherapy, TENS and balneotherapy. Complex therapies that combine the above mentioned methods is often more effective than the use of medications only.]

[Osteoporotic patient’s use of prescription drugs - pilot study]

BATKA Gábor, SZENTANDRÁSSY Andrea Éva, SZEKERES László

[BACKGROUND - In Hungary, the number of the highest mortality hip fractures is between 12 000-15 000 per year. The cost of treating hip fractures is several times higher than that of preventive medical therapy. Thus, the compliance of patients with osteoporosis is of great importance. METHODS - Using the informatical database of St. András Rheumatology Hospital at Héviz, we collected one year’s prescription drugs for osteoporosis and compared them with the number of drugs obtained by the patients, determined from National Health Insurance data. RESULTS - In general, the patients obtained 75% of prescription drugs. From the 4354 boxes of prescribed antiporotics, 3637 contained bisphosphonate (not considering vitamin D and calcium). Within this group, 88% of combination preparations were obtained, which is a greater ratio than that of non-combination bisphosphonates (84%). CONCLUSIONS - On the basis of our results, we posit that prescription of a combination preparation somewhat improves the patients’ compliance. The low concordance of vitamin D and calcium preparations is worrying.]

[Inhibition of receptor activator of nuclear kappa-B ligand: pathophysiology and preclinical data]

LAKATOS Péter, NÁDASI Edit

[Bone remodeling is a lifelong process, in which the balanced functions of osteoclasts and osteoblasts have a key role. In certain conditions, for example during the dramatical hormonal changes in the postmenopausal period, the upset of this balance leads to a pathologically increased bone loss. Such conditions lead to an increased bone loss, which results in an increased risk of fractures. Bone resorption is primarily regulated by a member of the tumor necrosis factor family, receptor activator of nuclear factor κB ligand, which plays a central role in the development, function and survival of osteoclasts. Catabolic effects of this ligand is inhibited by another member of the tumor necrosis factor family, osteoprotegerin, which binds to the ligand and prevents its interaction with its receptor, the receptor activator of nuclear factor κB. Osteoclast activity is at least partly dependent on the relative balance of the ligand and osteoprotegerin. It has been shown in a number of animal models that inhibition of the ligand markedly decreases bone resorption and increases cortical and cancellous bone volume, density and strength, without having any significant effect on other organs. On the basis of these findings, inhibition of receptor activator of nuclear κB ligand is a promising therapy of conditions characterised by increased bone loss. In phase 3 clinical trials, denosumab therapy significantly increased bone mineral density at various regions of the skeleton and significantly decreased the levels of bone turnover markers compared with placebo and alendronate therapy, and significantly decreased the incidence of new vertebral, total hip and nonvertebral fractures compared with placebo. On the basis of these findings, denosumab therapy offers a novel, revolutionary solution for the treatment of postmenopausal osteoporosis.]

[Treatment of childhood tumors of mesenchymal origin]

CSÓKA Monika

[Mesenchymal cells can be differentiated into skeletal muscle, smooth muscle, adipose tissue, fi brous tissue, bone and cartilage. Tumors can be originated from these tissues as benign tumors - fibroma, lipoma, osteoma, chondroma, haemangioma, myoma, etc. or as malignant tumors - in childhood, most commonly rhabdomyosarcomas, osteosarcoma, Ewing sarcoma, less often fi brosarcoma, liposarcoma or other rare types. Clinically, the outcome of these tumors have improved signifi cantly in the last decade due to the use of multi-modality treatment (chemotherapy, surgery, irradiation, in some cases targeted therapy). The better treatment results are based on early diagnosis and adequate management according to international treatment protocols in pediatric oncology centers.]

[Combined anterior and posterior approach to the tumours of the cervicothoracic junction: our experience]

BANCZEROWSKI Péter, LIPÓTH László, VERES Róbert

[Introduction - In the past, surgery of the pathologies of cervicothoracic junction carried high risk. Better knowledge of the anatomical situation and the increasing experience with anterior approach, corpectomy and spinal stabilization instruments have all made possible to remove the tumours of the cervicothoracic junction in a combined way. Case reports - The authors present six cases of spinal tumours where removal was done via anterior approach with partial clavicle and sternal resection. In two cases the anterior approach were combined with posterior tumour removal and fixation. Two of the cases were metastatic tumours, one lymphoma, one osteochondroma, one giant cell osteoid tumour and one malignant neurogenic tumour. The ventral approach gave a relatively wide window to explore the tumours and with the help of the operative microscope the tumour removal went fairly well. After total removal of the tumours the cervical spine were stabilized with own clavicle or iliac bone graft, titanium plate and screws. In patients with three-column involvement posterior fixation was made. The immediate recovery of the patients was well and there were no postoperative complications. Postoperative CT and MRI scans have great value in the early control after surgery as well as for the follow up of the patients. Conclusion - The anterior approach with partial clavicle and sternal resection combined with posterior approach and fixation seems to be feasible and safe method to explore and remove cervicothoracic junction pathologies.]

[Osteoid osteoma: diagnosis and treatment]

SHOAIB Shaikh, LOMBAY Béla

[Osteoid osteoma is a rare, generally small benign tumor that requires treatment due to the intense pain it causes. The aim of this review is to discuss the basics (pathophysiology, classification and imaging modalities of osteoid osteoma). Further, we have made an attempt to discuss in detail the technique and effects of surgery and radiofrequency ablation in the treatment of osteoid osteoma.]
