Lege Artis Medicinae - 2005;15(08-09)

[Pathologist have recognized arterial calcification for over a century described also by Virchow in the 19th century. Vascular calcification, an active mechanism, involves a complex, regulated process of biomineralization resembling osteogenesis. Evidence indicates that proteins controlling bone mineralization are also involved in the regulation of vascular calcification. The atherosclerotic plaque calcification can be easily detected noninvasively with radiological methods currently available and it correlates with the amount of atherosclerotic plaque. Also, it serves as a surrogate measure for atherosclerosis, allowing preclinical detection of the disease. There are several examples for the relationship between hyperlipidaemia and increased loss of bone mass. It is not surprising that the base drugs for osteoporosis also have the characteristics for lowering vascular calcification and are antiatherogenous and antilipaemic drugs. The clinical importance ot these facts is that vascular calcification is associated with higher risk of cardiovascular events. In the summary, the authors review the four histopathological types of arterial calcification and the molecules and proteins involved in these processes.]

[RARE CAUSES OF GASTROINTESTINAL BLEEDING]

TAHIN Balázs, TÓTH Csaba, KOVÁCS Attila, DOBOS András, DÖBRÖNTE Zoltán, NAGY Lajos, TARABÓ Zoltán, MÁRKUS Béla, GARZULY Ferenc

[INTRODUCTION - The efforts to eliminate the source of gastrointestinal bleeding are not always successful, especially in rare diseases. CASE REPORT - In three patients causes and sites of haemorrhages were detected only at autopsy. The first patient underwent upper gastrointestinal endoscopy as well as surgical exploration. The post-mortem examination showed multiple gastric Dieulafoy’s vascular lesion. The second patient was examined by repeated upper gastrointestinal panendoscopy, but the site of haemorrhage remained unknown. Two polyps were removed during colonoscopy. Unexpected haemorrhage caused sudden death. The aortobifemoral graft, which had been implanted two years earlier had destroyed the duodenal wall, a fistula developed and caused haemorrhage. The third patient had had a right hemicolectomy abroad because of angiodysplasia, but the bleeding episodes repeated. The cause was revealed at autopsy as angiodysplasia of the small bowel. CONCLUSION - Dieulafoy’s disease can sometimes be discovered only by repeated endoscopy but sudden death may precede diagnosis. In the presence of an aortic graft we have to keep in mind that this could be the cause of catastrophic bleeding. Therefore, the examinations should be performed immediately - endoscopy has to involve the distal part of the duodenum - and operation is urgent. Angiodysplasia of the small bowel is a rare site of angiodysplasia which requires special diagnostic procedures like capsule endoscopy. The multiplicity of the disease and the age of the patients made the diagnostic difficult.]

[TRAVEL MEDICINE IN GP PRACTICE]

FELKAI Péter, KOVÁCS Erzsébet

[The authors describe the basic ideas of travel medicine, as a newly introduced interdiscipline of the medical science in Hungary. Recently, this segment is considered to be the part of Insurance Medicine, on the other hand the methods and the practice of the travel medicine is based on the other medical specialities’ knowledge. Due to the growing number of travellers in our country as well as the consequences of the joining Hungary to EU, travel medicine could play an important role in the improvement of the Hungarian travellers’ attitude to their health care status, the prevention against the emerged infectious diseases, and in the medical assistance for the international tourism. Travel medicine also a good guideline for the fit-for-travel considerations, made by the GPs. Hungary with its advantageous geographical position appears to be an excellent stopover for any medical evacuation from East European or other surrounding countries. That is why we would like to establish a first travel medicine facility in central Europe. It is expectable that the Hungarian travellers require more and more information regarding to their health care possibilities and prevention during their trip. The first authentic person is being asked by the patients’ are GPs. The GP’s tasks are: diagnosis and the treatment of travel related diseases, the pre-travel advices. All the mentioned factors are a new challenge for the GPs in Hungary.]

[The role of bone turnover markers in the diagnosis and therapy of osteoporosis]

HONTVÁRI Lívia, KRÁNICZ Ágota

[Osteoporosis is a metabolic bone diseasecharacterised by decreased bone mass andimpaired bone turnover, which leads to anincreased risk of fractures and significantmorbidity and mortality. Its social and pub-lic health impact and the importance of itsearly and accurate diagnosis are indis-putable. The aim of timely and efficienttherapy is to improve bone quality as wellas to prevent the dreaded complications ofbone fractures. In clinical practice, labora-tory diagnosis of biochemical bone mark-ers are particularly important for therapeu-tic monitoring. In this article, reviewing lit-erature data, we discuss bone-specificmarkers from the clinician’s perspective,and highlight their importance in everydayclinical practice. ]

[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 results of the Ca-Intake.hu study - Calcium supplementation as a part of basic therapy of osteoporosis is more than a routine step]

LAKATOS Péter, SPEER Gábor, DOMBAI Péter, ZAJZON Gergely

[Calcium intake is considered the base therapy of osteoporosis treatment. It is known that in case of inadequate calcium intake, specific anti-osteoporotic drugs are inefficient. In the present study, we aimed to investigate the alimentary and supplementary calcium intake among Hungarian osteoporotic patients, using a nationwide representative survey. Patients with osteoporosis were enrolled in the study. We determined the total alimentary calcium intake and the average supplementary dose. In some cases, total calcium intake was lower than recommended, in other cases it was significantly higher than that. In some cases, bone density showed a positive correlation with calcium intake. Vitamin D supplementation complied with current recommendations.]

[Femoral head osteonecrosis in a child with acute lypmhoblastic leukemia]

GÁCS ZSÓFIA, KOVÁCS GÁBOR, HOSSZÚ ÉVA

[INTRODUCTION - The treatment of pediatric leukemia has become increasingly successful, with a survival rate over 80%. Thus interest has been increasingly focused on the long-term side-effects of the treatment. The questions of reduced fertility rate, occurance of second malignancies, cardiomyopathy, impaired renal and pulmonal function have been extensively studied. Changes of bone metabolism in connection with the disease itself and the treatment have been analysed in the past decade. CASE REPORT - We present the case of a 15-year-old boy with acute lymphoblastic leukemia, who had bone pain soon after the diagnosis. During the course of chemotherapy his complaints were fluctuating, and he developed severe osteoporosis. The level of a bone resorption marker, β-CrossLaps, was elevated. In the second year of therapy an acute pain of the left hip occured with fever and restriction of joint movement, which was diagnosed and treated as osteomyelitis. A few months later avascular necrosis of the left femoral head was revealed. Both pharmaceutic (calcium, vitamin D, calcitonin, bisphophonate) and orthopedic treatment were used, as a result bone mineral density and movement restriction improved; his leukemia is now in remission. CONCLUSIONS - The factors influencing bone metabolism in leukemic children are reviewed. Firstly the effects of malignant cells on bone mineral content are analyzed, then the chemotherapeutic drugs’ mechanisms of action are examined extensively. The direct and indirect effects of secondary factors (hospitalization, immobility, lack of sun exposure, malabsorption, immunsuppression, peripheral neuropahty) are also analyzed. The advantages and disadvantages of drugs used in preventing and treating childhood osteopenia are reviewed.]
