[Objectives: Was to evaluate 10-year probability of hip fracture and a major osteoporotic fracture using the FRAX algorithm, vitamin D status, bone mineral density (BMD) and biochemical markers of bone turnover in men over 50 years of age with type 2 diabetes (T2DM). We compared FRAX-predicted 10-year fracture probability, levels of 25-hydroxyvitamin D (25-OH-D), markers of bone turnover and bone mineral density at L1-L4 (LS) and femur neck (FN) in 68 men with T2DM with an age- and gender-matched group (n=68). The mean (range) age of the T2DM group was 61.4 (51-78) years. The prevalence of hypovitaminosis D (25-OH-D <75 nmol/L) was 59%. The mean (range) FRAX hip fracture and FRAX major osteoporotic fracture was 0.7 (0-2.8)% and 3.2 (0-8.5)%, respectively. BMD at the FN (0.974 gm/cm2 vs. 0.915 gm/cm2; p = 0.008) and LS (1.221 gm/cm2 vs. 1.068 gm/cm2; p < 0.001) was significantly higher in the T2DM cohort as compared to the healthy age matched males. 25-OH-vitamin D (67.7 nmol/L vs.79.8 nmol/L; p < 0.001), crosslaps (0.19 μg/L vs. 0.24 μg/L; p = 0.004) and osteocalcin (13.3 μg/L vs. 15.7 μg/L; p = 0.004) were significantly lower in the T2DM group. There was no difference in FRAX-related fracture probability between the two groups. The increased BMD in T2DM and the lack of inclusion of T2DM as a risk factor in the FRAX algorithm are probable explanations for the discordance between literature-observed and FRAX-related fracture probabilities.]

[Treatment of osteoporotic vertebral compression fracture with PMMA augmented pedicle screw fixation]

PADÁNYI Csaba, MISIK Ferenc, PAPP Zoltán, VITANOVICS Dusan, BALOGH Attila, VERES Róbert, LIPÓTH László, BANCZEROWSKI Péter

[Background - Over the last few decades many innovative operation technique were developed due to the increase of porotic vertebral fractures. These new techniques aim to reach the required stability of the vertebral column. In case of significant instability, spinal canal stenosis or neural compression, decompressive intervention may be necessary, which results in further weakening of the column of the spine, the minimal invasive percutan vertebroplasty is not an adequate method to reach the required stability, that is why insertion of complementary pedicular screws is needed. Considering the limited screw-fixing ability of the porotic bone structure, with this new technique we are able to reach the appropriate stability of cement-augmented pedicle screws by dosing cement carefully through the screws into the vertebral body. We used this technique in our Institute in case of 12 patients and followed up the required stability and the severity of complications. Methods - Fifteen vertebral compression fractures of 12 patients were treated in our Institute. Using the classification proposed by Genant et al. we found that the severity of the vertebral compression was grade 3 in case of 13, while grade 2 in case of two fractures. The average follow up time of the patients was 22 months (12-39), during this period X-ray, CT and clinical control examinations were taken. During the surgery the involved segments were localised by using X-ray and after the exploration the canulated screws were put through the pedicles of the spine and the vertebral body was filled through the transpedicular screws with bone cement. Depending on the grade of the spinal canal stenosis, we made the decompression, vertebroplasty or corpectomy of the fractured vertebral body, and the replacement of the body. Finally the concerned segments were fixed by titanium rods. Results - In all cases the stenosis of spinal canal was resolved and the bone cement injected into the corpus resulted in adequated stability of the spine. In case of six patients we observed cement extravasation without any clinical signs, and by one patient - as a serious complication - pulmonary embolism. Neurological progression or screw loosening were not detected during the follow up period. Part of the patients had residual disability after the surgery due to their older ages and the problem of their rehabilitation process. Conclusion - After the right consideration of indications, age, general health condition and the chance of successful rehabilitation, the technique appears to be safe for the patients. With the use of this surgical method, the stability of the spine can be improved compared to the preoperative condition, the spinal canal stenosis can be solved and the neural structures can be decompressed. The severity of complications can be reduced by a precise surgical technique and the careful use of the injected cement. The indication of the surgical method needs to be considered in the light of the expected outcome and the rehabilitation.]

[Recent studies have shown that adequate vitamin D level is essential in the maintenance of normal immunological status and presumably, it has a remarkable role even in the healing of some diseases. Vitamin D deficiency is a common phenomenon worldwide. Presently, the accepted marker of vitamin-D status is the total-25-hydroxy- D-vitamin [t-25(OH)D], its level depends on the specific (DBP) and aspecific (albumin) binding proteins. As known, the level of binding proteins may change in the hospitalised patients therefore, the presently used marker could not be reliable for the vitamin status in these cases. Our aim was to measure the D-vitamin supply among hospitalized patients, taking into account the level of binding proteins. METHODS - 401 cases (average age 70±14 years) were sorted from Internal Medicine (IM; 68), Intensiv Care Unit (ICU; 58), Traumatology (203 patients suffered hip fracture) and Dialysis Center (72 patients with end stage renal disease). 127 age and sex matched persons with active lifestyle served as control group. We determined t-25(OH)D, DBP, parathormon (PTHi), albumin and the albumin corrected Ca level. The bioavailable and free vitamin fractions and the free index were calculated. RESULTS - Based on the measured t- 25(OH)D, patients have more frequently suboptimal D-vitamin levels, compared to the control group (66% vs. 97%). Severe Dvitamin deficiency occured nearly 8 times more likely (6% vs. 47%) in the hospitalized patients. Chronic renal failure and malignant diseases seem to be significantly negative influencing factors in the metabolism of the vitamin D. The level of DBP, albumin, t-25(OH)D, Bio-25(OH)D was significantly lower in the patients who died. CONCLUSION - In most cases, t-25(OH)D levels show similar results about the vitamin- D supply than other calculated 25(OH)D fraction ,except for the patients of ICU and IM . The t-25(OH)D, the Bio- 25(OH)D, the DBP and the albumin levels seem to be a good prognostic marker of the outcome.]

[Tailored cranioplasty using CAD-CAM technology]

VITANOVICS Dusan, MAJOR Ottó, LOVAS László, BANCZEROWSKI Péter

[Objective - The majority of cranial defects are results of surgical intervention. The defect must be covered within resonable period of time usually after 4-6 week given the fact that the replacement of bone improve the brain circulation. Number of surgical techniques and materials are available to perform cranioplasty. Due to favorable properties we chosed ultra high molecular weight polyethylene as material. In this paper the authors show a procedure which allows tailored artificial bone replacement using state of art medical and engineering techniques. Methods - between 2004 and 2012, 19 patients were operated on cranial bone defect and a total of 22 3D custom- designed implants were implanted. The average age of patients was 35.4 years. In 12 patients we performed primary cranioplasty, while seven patients had the replacement at least once. Later the implants had to be removed due to infection or other causes (bone necrosis, fracture). All patients had native and bone- windowed 1 mm resolution CT. The 3D design was made using the original CT images and with design program. Computer controlled lathe was used to prepare a precise-fitting model. During surgery, the defect was exposed and the implant was fixed to normal bone using mini titanium plates and screws. All of our patients had control CT at 3, 6 and12 months after surgery and at the same time neurological examination. Results - Twenty-one polyethylene and one titanium implants were inserted. The average follow-up of the patients was 21.5 months, ranged from two to 96 months. We follow 12 patients (63.15%) more than one year. No intraoperative implant modifications had to be made. Each of the 22 implant exactly matched the bone defect proved by CT scan. No one of our patients reported aesthetic problems and we did not notice any kind of aesthetic complication. We had short term complication in three cases due to cranioplasty, subdural, epidural haemorrhage and skin defect. Conclusion - Polyethylene is in all respects suitable for primary and secondary cranioplasty. Combined with 3D CADCAM method excellent aesthetic and functional result was achieved. In our study no case of infection occured. Proper preoperative preparation is important.]

[ROLE OF PATIENT CLUBS IN SUCCESSFUL TREATMENT OF OSTEOPOROTIC PATIENTS]

SOMOGYI Péter, GAÁL János, SPEER Gábor

[The significance of osteoporosis is well known, however, the number of patients receiving treatment is only a small fraction of ideal. Besides, the fact that the population is uninformed, the difficulties of making an appointment with a specialist and the unsatisfactory communication of the doctor all play a part in the fact that a high proportion of patients receiving mediation give up treatment prematurely. The Inter - na tional Osteoporosis Foundation supports the establishment of public patient clubs with regular training courses and grants and by doing so it also acknowledges their importance in the prevention and treatment of osteoporosis. The publication, based on the questionnaire filled in by the members of the first Hungarian patient club, the Hungarian Society of Osteopo - rosis Patients in district 3rd, introduces the Hungarian results and points out how important patient clubs are in increasing the success of treatment and it also draws attention to the necessity of establishing further patient clubs in the future.]

[Prosthodontic treatment of an edentulous epileptic patient with an implant-retained overdenture. A case report]

KÁROLYHÁZY Katalin, SCHMIDT Péter, BOGDÁN Sándor, HERMANN Péter, ARÁNYI Zsuzsanna

[This report describes the treatment of a completely edentulous, mentally retarded patient with epilepsy with an implantretained overdenture, anchored by a locator system. The intractable epileptic condition of the patient with frequent grand mal seizures and complex partial seizures required a stable, well retained prosthesis, however the maxilla and the mandible were severely atrophied. The bone volume of the maxilla allowed the placement of only two implants at the region of the canines, compared with the generally required four. On long time recall, after one year, patient’s chewing ability was satisfactory.]

[Forgotten agent: raloxifene]

BENKŐ Ágota

[The largest group of the patients with osteoporosis is postmenopausal women characterized by a state of menopausal hormone deficiency which is results in accelerated bone loss. This increased bone resorption significantly elevates the risk of bone fractures including the most common type, i.e. vertebral fractures. In addition to the increased risk of fractures, estrogen deficiency affects other organs, thus, increasing the incidence of cardiovascular diseases, cancers, mood disorders and the symptoms of menopausal syndrome in women after menopause. In postmenopausal osteoporosis, the primary objective is to maintain the existing bone mass, a priority for the prevention and treatment of bone fractures. Hormone deficiency may be prevented by the administration of estrogen but the treatment may have adverse effects such as increased risk of endometrial cancer. An etiological therapy is desirable where the compound used for treatment exerts effects similar to that of estrogen to prevent postmenopausal bone loss as well as reduces the risk of cardiovascular disease without the stimulation of reproductive tissues.]
