[INTRODUCTION -The aim of this study was to examine the effect of intranasal salmon calcitonin therapy on bone mineral density in idiopathic male osteoporosis without vertebral fractures. MATERIALS - The randomised, prospective, controlled trial involved 71 male patients (mean age 59±6 years) suffering from idiopathic osteoporosis (lumbal spine and femoral neck T-score <-2.5) without vertebral deformity. Study design: Treatment protocol: Patients in the control group (n=31) received 400 IU Vitamin D + 1000 mg elemental calcium daily while the treatment group (n=40) received 400 IU Vitamin D, 1000 mg elemental calcium and 200 IU calcitonin nasal spray daily, by an intermittent monthly dose. METHODS - 1. Osteodensitometry: lumbar spine (L2-4) and femoral neck were measured by dual photon absorptiometry (LUNAR DPX-L, USA), whereas non-dominant radius was measured by single photon absorptiometry (NK 364, Gamma, Hungary). 2. Roentgenomorphorphometry was done onthoracic IV to lumbar IV spines and deformity indeces were calculated. The treatment period was 18 months. Examinations were performed at baseline and at the end of treatment.The primary end-point was the change of bone density measured by osteodensitometry. Secondary end-points included the side effects of medication. RESULTS - Nasal calcitonin was associated with significant increase in bone mineral density at the lumbar spine (+3.5±4.3% vs. +0.83±6.4%, p=0.04) and the femoral neck (+3.2±3.9% vs. -0.68±5.7%, p=0.004). No significant difference was observed at the radius between the treatment groups (+1.4±8.8% vs. +1.4±10.9%, p=0.98). No osteoporotic fractures occurred in the treated group, but there were 3 fractures in the control group. Treatment was well tolerated with no premature discontinuations nor significant side effects compared to the control group. CONCLUSION - 200 IU salmon calcitonin nasal spray used daily, intermittently proved to be an effective and safe therapy in male idiopathic osteoporosis.]

[Results obtained by pulsed electromagnetic field therapy in delayed healing or pseudoarthrosis of various fractures]

KRICSFALUSY Mihály, UDVARDY Csaba, LITVAI Gabriella

[INTRODUCTION - Delayed healing or the development of pseudoarthrosis after a conservatively or surgically treated fracture significantly prolongs the time of patient recovery and rehabilitation.The aim of the study was to investigate the influence of pulsed electromagnetic field (PEMF) therapy on delayed fracture healing or pseudoarthrosis in fractures of various long bones. PATIENTS AND METHODS - Twenty-one patients with abnormal fracture healing were treated ambulatorily a mean of 8.7 months after the injury with PEMF by a Biostim device (IGEA, Italy) for a mean of seven weeks. RESULTS - Overall, fracture healing was established in 15 patients, which corresponds to a recovery rate of 71.4%. By excluding the two patients, however, in whom bone restoration was inhibited by mechanical factors, healing rate increases to 78.9%. Pain intensity decreased substantially; function and endurance of the limb improved in every patient. CONCLUSIONS - These results as well as international data justify the need for wide-spread application of biophysical bone healing enhancement methods in Hungary, the first step of which is to popularize it among clinicians.]

[Percutaneous vertebroplasty in the treatment of osteoporotic vertebral compression fractures]

KULCSÁR Zsolt, SZIKORA István, BERENTEI Zsolt, MARTOS János, NYÁRY István

[Percutaneous vertebroplasty is a minimally invasive procedure that is increasingly applied for the treatment of osteoporotic compression fractures. The authors discuss its indications, patient selection criteria, the issue of diagnostic imaging, the technique of the procedure, its potential complications, review the literature on post-procedure pain relief, and briefly present their own experience in the treatment of osteoporotic fractures. Vertebroplasty is indicated for patients with severe, persistent, often incapacitating focal back pain not responding to standard medical therapy, which is related to the collapse of one or more vertebral bodies. Patients selected carefully by the clinical symptoms and the imaging studies usually respond promptly to the treatment, experience significant pain relief, improvement of the quality of life, and an increase in mobility.Vertebroplasty is a safe procedure with relatively low complication rates.The potential neurological complications, however, necessitate an instantly available neurosurgical background.]

[Effect of cigarette smoking on bone density]

MÉSZÁROS SZILVIA, FERENCZ VIKTÓRIA, DELI Mónika, BORS Katalin, HORVÁTH CSABA

[INTRODUCTION - Smoking is associated with a decreased bone mass and increased risk of osteoporotic fractures.The aim of this study was to investigate the impact of current tobacco smoking to bone mineral density (BMD) in Hungarian females. PATIENTS AND METHODS - We measured BMD in 43 (25-72 yrs) smoker and 43 age- and BMI-matched non-smoker women by dual X-ray absorptiometry (Prodigy, GE Lunar) at the lumbar spine and proximal femur and by single photon absorptiometry at the radius midshaft of the non-dominant side (NK 364, Gamma). RESULTS - Osteoporosis (T-score at any measured site below - 2.5) was found to be more common among smokers compared to non smokers (63.6% vs 36.4%, χ2-test p=0.009). Among premenopausal women no difference was found in BMD between the two groups, whereas postmenopausal smoker women tended to have a lower BMD value compared to those who didn’t smoke. In postmenopausal women a decrease of borderline significance was found in lumbar BMD (0.977 vs 1.04; p=0.06). CONCLUSION - Our observation suggests that there is only a slight decrease in bone mass due to smoking, however, added to menopausal bone loss this effect can be a significant contributor to the increased fracture risk of involutional age.]

[The effect of biological therapy on generalised osteoporosis in patients with rheumatoid arthritis]

JUHÁSZ Péter

[In rheumatoid arthritis, the inflammation and damage of multiple joints can lead to generalised osteoporosis. This process is mostly mediaated by cells and cytokines that are also important for maintaining inflammation, by inhibiting bone formation as well as stimulating bone resorption. Data from the literature show that biological therapies that effectively decrease inflammation can also stimulate bone formation and inhibit bone resorption. This results in an increased bone density and bone protection, which is highly important to prevent subseqent fractures.]

[Significance of quantitative ultrasound bone densitometry and its introduction into pediatric bone medicine]

HOSSZÚ ÉVA, HAZAY Máté, LIPTOVSZKY Janka

[INTRODUCTION - Quantitative Ultrasound (QUS) examination of the bones provides information about not only bone mineral mass but also its quality. Adaptation of the method to the continuous growing of body size allowed its pediatric use. However, for introduction into routine use, a normal reference range in healthy children has to be established. The primary aim of this study was to establish the Hungarian reference range for QUS of the bone - in both genders and across a wide range of ages. As a secondary aim, QUS and the bone density were compared to internationally accepted data to comparatively determine correlations of specific QUS measurements to photon absorption based values. SUBJECTS AND METHODS - Measurement was performed on the calcaneus by Achilles Insight (Lunar, WI) device. Bone Mineral Density (BMD) of the lumbar spine was measured using the Double X-ray Absorptiometry (DXA) device DPX-L (Lunar, WI). Latter was also used to measure total body calcium content. Measurements were performed in 154 healthy boys and girls aged 5 to 18 years. We analyzed data as a function of age, and correlated results of he two types of measurement. RESULTS - Gender-specific reference ranges for normally developing children of the above ages were built up for Broadband Ultrasound Attenuation (BUA) and Speed of Sound (SOS). BUA showed the best correlation to BMD. SOS and Stiffness Index (SI) derived from BUA and SOS, correlated weaker to BMD, consonantly with the fact that SOS reflects bone elasticity (quality) rather than bone mineral mass. CONCLUSION - These newly constructed normal ranges can provide a basis of performing pediatric bone examinations using QUS, which is less expensive and more mobile.]

[Evaluation of bone mineral density in renal form of primary hyperparathyroidism]

CSUPOR EMŐKE, SZŰCS János, MÉSZÁROS SZILVIA, LAKATOS Péter, TÓTH EDIT, HORVÁTH CSABA

[INTRODUCTION - The most frequent manifestations of primary hyperparathyroidism are renal stones or calcipenic osteopathy. The aim of authors was to examine how bones are affected (change of bone mineral density and frequency of fractures) in the renal form of primary hyperparathyroidism. METHODS - Mean age of the patients was 57 years (26 -81 years), (4 men, 33 women). Bone mineral density was measured in the lower third of the radius, femoral neck and lumbar 2-4 vertebrae by densitometers. Moreover, occurrence of fractures and biochemical parameters characteristic for hyperparathyroidism (serum parathyroid hormone levels, calcium, phosphorus, alkaline phosphatase, urinary calcium/ creatinine) were examined. RESULTS - Bone mineral density was normal in 6 cases, osteopenic in 10 patients and 21 patients had osteoporosis. Altogether five patients had fractures. Bone mineral density and biochemical parameters were not different in patients with or without fractures. CONCLUSIONS - Bone mineral density decreases in renal form of primary hyperparathyroidism even if there is no bone disease in the clinical picture. Therefore, bone mineral density measurement is advisable for every patient with hyperparathyroidism.]
