LAM Extra for General Practicioners - 2014;6(03)

[The medical impact of hepatitis C (HCV) is significant worldwide. The main consequences are chronic hepatic injury, cirrhosis, and hepatocellular carcinoma formation. The estimated global prevalence is 3% with 180 million infected people worldwide. The prevalence <1% in Hungary. The prevalence increased between 1990 and 2005 in East Asia, Western Europe, and West sub-Saharan Africa. There is characteristic geographical distribution of the main HCV genotypes. The mode of transmission can not be identified of 40% of cases. The most frequent transmission is the intravénás drug injection in the developed countries, and unsafe health procedures in developing countries. The sensitive, nucleic acid amplification testing, identification of high-risk groups, development of vaccination would help the HCV prevalence in the future. ]

[The impact of vitamin D in infertility and the role in pregnancy and in nursing period]


[Various medical associations issue different recommendations for the prevention and treatment of vitamin D deficiency. These significant differences are partly explained by the different definition of normal vitamin D level and the use of completely different mathematical models to predict the increase in vitamin D level as a response to therapy. According to the Institute of Medicine, the target vitamin D level is 20 ng/ml, whereas the Endocrine Society recommends 30 ng/m as the minimum target value. These differences show that the two Society have different views on the risk of adverse effects. Screening, however, is not recommended by either society. In this review I summarize the role of the vitamin D supplementation in the prevention of infertility. Also, I suggest the protective effect of the vitamin D during the pregnancy. In my opinion screening program against D hypovitaminosis should be performed in case of infertility and in pregnancy, because data show a protective role of vitamin D against many disease of newborn. ]

[The possibilities of pharmacological treatment of obesity]

PADOS Gyula, SIMONYI Gábor, BEDROS J. Róbert

[There have been attempts to treat obesity with medicines for nearly 100 years, since the discovery of ephedrine. For decades amphetamine derivates and agents stimulating or inhibiting the release of noradrenaline and dopamine have been applied. However, most of theses drugs had to be gradually withdrawn, due to their adverse effects on the cardiovascular and central nervous system or their sympaticotonic effect. Dexfenfluramine (Isolipan), which was introduced in the 90s, did not have such side effects, but it turned out to potentially cause valvular heart disease. Finally, sibutramin (Reductil) was introduced, which again had to be withdrawn in 2010 due to its hypertensive and cardiovascular side effects. After all, we were left without any appetite-suppressant drugs. Orlistat therapy, (Xenical 120 mg, alli 60 mg - OTC), which inhibits the absorption of fat, can eliminate only 30% of the consumed food's fat content, at the price of gastrointestinal side effects. The latest result of research carried out wordwide is that in 2012 the FDA approved commercial distribution of the selective 5HT2/c serotonin agonist lorcaserin (Belviq), which enhances satiety, in the USA. Unfortunately, in 2013 the EMEA temporarily postponed the lauch of this drug, until certain adverse effects are excluded. For diabetic patients, the GLP-1 agonist exenatid and the GLP-analog liraglutid, which can also reduce body weight, are available in the form of injections. ]

[Recognition of the characteristics of rare types of arthritis]

ROJKOVICH Bernadette, MÉSZÁROS Györgyi

[Recognition of the characteristics of arthritis is crucial for making a correct diagnosis. Several aspects of the history and physical examination could help the diagnosis, such as the mode of onset (acute, insidious), duration of symptoms (self-limiting, chronic), number of affected joints (mono-, oligo-, polyarthritis), distribution of joint involvement (symmetrical, asymmetrical), localisation of affected joints (axial, peripherial) and sequence of involvement (additive, migratory, intermittent). Other important aspects for the correct diagnosis are the characteristics of the patient (gender, age, family history) and the presence or absence of extra-articular features of disease. The articular pattern may change with time in the course of a disease, and the single clinical pattern of joint disease may correspond to more than one diagnosis. Evidence of some distinct articular patterns may limit the spectrum of diagnostic options and reduces unnecessary diagnostic testing. The diagnostic process may require the addition of laboratory examination, imaging techniques, and other tests to refine the analysis. In this article, we report a case where joint punction and histological elucidation was necessary to make the correct diagnosis, because a syndrome of acute, destructive sterile arthritis mimicking articular infection might be present in a variety of joint disorders. In this paper, we highlight those characteristics that are distinctive for particular rheumatological disorders, in order to help starting treatment early.. In a substantial number of patients the cause of the diseases remains undetermined. However, a detailed anamnesis and physical examination remain the cornerstone of a diagnostic evaluation. ]

[Hungarian dialysis statistics: changing trends in the renal epidemiology]


[In the last 30-35 years, dialysis care in Hungary has been a major development: both the incidence and prevalence of patients have increased year by year. Over the last decade, growth has slowed and is becoming more and more stabilized (similar trends can be seen in dialysis statistics in developed countries). Behind the dialysis indication the acute kidney injury (AKI) is more common than the end-stage renal disease (ESRD). The latter incidence has been stable for last 6 years (200-230 patient/million population). The annual average growth rate of prevalent dialysis patients was only 0.9%/year in the last 6 years. Among prevalent dialysis patients, the proportion of diabetic patients has remained unchanged for 10 years (26-27%), but those have increased who had hypertension nephropahty. The average age of incident and prevalent dialyzed patients has decreased gradually over the past 8 years (between 2009 and 2017 incident rate was from 67.1 to 63.0 years, prevalent rate was from 65.6 to 61.8 years). Unfortunately, just over half of the patients who dialyzed due to chronic kidney disease (CKD) have reached dialysis day 91. This is due to the high proportion of patient who was in urgent need of dialysis. In chronic hemodialysis (HD) program, the proportion of patients treated with arterovenous fistulas (AVF) decreases, while the rate of central venous catheter (CVC) users increases. The Hungarian peritoneal dialysis program in Europe is very good. The number of prevalent patients receiving renal replaement therapy (RRT) in Hungary in 2017 was 1005 for 1 million inhabitants.]

[Epidemiological surveillance systems used by international organisations in military crisis management operations]

KOPCSÓ István, KISS Antal Zsolt

[Facing new challenges and growing requirements, the renewal and adjustment of doctrines, methods and technology is an indispensable progressive need for modern militaries. In order to achieve the maximal protection of troops and conservation of fighting strength, innovation is continuous and has greatly accelerated in the whole spectrum of Force Health Protection. Owing to the development of technology, portable capabilities that had been available only in the hinterland have become available in the military medical support area. Utilising mobile information technology solutions, the continuous, real-time information flow between the tactical level medical units and the higher level medical analysts and decision makers has become technically feasible, which results in a significant widening of epidemiological surveillance capabilities as well. We discuss the current challenges of expeditionary- type military operations and their general epidemiological aspects and the morbidity reporting and monitoring systems used in international military missions. Furthermore, we overview the milestones of the development of the NATO near-real-time epidemiological surveillance system, the NATO Deployment Health Surveillance Capability, which functions as a branch of the Budapestbased multinational NATO Centre of Excellence for Military Medicine.]

[Therapy of isolated systolic hypertension III.]


[In the elderly and very elderly (˃80 yrs), a wealth of data from large clinical trials are available, showing the necessity of treatment mostly with drug combinations - fix-combinations are preferred for increasing the adherence/persistence to therapy. Using diuretics, ACE-inhibitors/ARBs with calcium antagonists, and in special cases diuretics and beta blockers are also suggested by recent European guidelines (ESH, HSH). The target is <140 mmHg, but in octogenarians <150 mmHg. Some studies are pressing for even lower SBP (to around 120 mm Hg), but it seems to be wise to balance advantages/disadvantages, so the optimal SBP may be around 130 mmHg.]

[Hypertension and diabetes mellitus]

SZEGEDI János, KISS István

[Hypertension and diabetes mellitus are endemics which affect large crowds; they play an important role in the morbidity and mortality of the population. Both diseases are cardiovascular risk factors, their co-occurrence increases the coronary risk. According to forecasts, there will be 60% increase in the number of hypertensive patients by 2025; it will affect 29% of the world’s adult population, 1.56 billion people. The number of patients with diabetes increases in all countries; 552 million diabetic patients should be expected by 2030. The simultaneous occurrence of both diseases may be a coincidence, but there is also causal relationship between the two diseases (diabetic nephropathy, metabolic syndrome). The two diseases often occur in endocrine diseases, and in connection with medicinal therapy (steroids, etc.). The simultaneous occurrence of these two diseases determines the therapeutic strategy. During the prevention and treatment of both diseases, the change in lifestyle has an important role (obesity, salt intake, physical activity).]

RIHMER Zoltán, GONDA Xénia, DÖME Péter

[The prevalence of major and minor depression in Parkinson’s disease is around 30-40% but, unfortunately, depression remains frequently underrecognized and often undertreated. However, recognition and appropriate treatment of depression in patients with Parkinson’s disease is essential for improving the cross-sectional picture and longitudinal course. This review focuses on the epidemiology, pathophysiology and different treatment modalities of depression in Parkinson’s disease.]
