Lege Artis Medicinae - 2005;15(07)

[Malignant melanoma, the disease originating from pigment cells of the skin, mucous membrane, eye and rarely from other tissues, shows increasing incidence in the Caucasian population. The Hungarian statistical data correspond with the data of other countries. In the early stages of malignant melanoma surgical removal of the tumor is often curative, but patients with disseminated tumors have a poor survival rate. Regrettably, in Hungary the majority of melanoma patients are diagnosed with advanced tumors, with nodal or systemic metastasis. Physicians working in other fields of medicine have a great responsibility in patient education and in early detection of susceptible pigmented lesions. Diagnosis and treatment of malignant melanoma requires an experienced dermatologist. The clinical diagnosis of melanoma is aided by several new techniques, like digital dermatoscopy. In recent years, surgical therapy of malignant melanoma has changed: today we routinely perform sentinel node biopsy. This type of surgical technique requires experience. In advanced disease the use of chemotherapy and immunotherapy requires onco-dermatological experience. Educating the public and physicians provides the basis for prevention. Survival rate is mainly dependent on the quality of primary care which determines survival rate, therefore it is essential that patients with melanomas are followed up in onco-dermatological centers.]

[SUBCLINICAL THYROID DISEASES]

FÖLDES János, WINKLER Gábor

[More and more data are indicating that subclinical thyroid diseases can not be regarded as innocuous states. It seems very likely that slight changes in the serum thyroid hormone levels, still within the normal reference range, are sensed beside the pituitary also by other tissues and organs and their function may become abnormal. Considering these problems, it would be advisable to elucidate the proper time to start treatment, whether it is beneficial or not and to determine what the risks are for the applied therapy. Though the recommended guidelines for the management of subclinical thyroid diseases are becoming more and more evident, many questions remain still unanswered. It is not advisable to start an overzelous therapy, however, a too long waiting time for the installation of treatment could also be harmful. Large prospective and randomized trials are needed to clear these questions. This seems to be an urgent task, since due to their high prevalence, subclinical thyroid dysfunction might be regarded as a public health problem.]

[THE USE OF GENERIC DRUGS IN THE MEDICAL THERAPY OF EPILEPSY]

RAJNA Péter

[The author demonstrates the relationship between the innovative and generic antiepileptic drugs regarding the clinical aspects. Among the requirements for the registration of generics one can find small differences in the prescribed and the practical levels of bioequivalence. An important but not widely known fact is that these differences can lead to clinically important alterations if the effects of different generics or the effects on high risk patients are compared. While the increasing market of generics is due to economical factors (and rarely due to medical decisions), the safety of the drugs becomes extremely important. From this aspect, special patient populations eg. children, elderly people or patients with multiple illnesses under multidrug treatment are necessarily of greater medical importance. The characteristics of the antiepileptic drugs on the elderly patients, their increased sensitivity to particular adverse events and the possible somatic side effects are discussed in details. The type of epilepsy also has its special characteristics and is important in the choice of the most successful medicine. The development of the antiepileptic drugs shows a positive direction for their efficacy. In the discussion the author points out three main ways for using generic drugs: prescription of generic drug in monotherapy or as an additive in newly diagnosed patients, the exchange of the innovative agent to a generic and the exchange of one generic to another. The author also mentions the legal points and criticizies the regulations available in some countries allowing a free exchange of the bioequivalent drugs without the agreement of the physician or the patient. The final part of the paper reviews the results of the comparative studies on the effects of the generic antiepileptic drugs and the experiences of the physicians of their application based on surveys performed with questionnaires. The data of the literature is compared to the Hungarian methods of application and to his own experience. Recommendations for the application of generic antiepileptic drugs are summarized in „twelve points“.]

[FEMALE SEXUAL DYSFUNCTION]

ROMICS Imre

[Based on the literature data reflecting test results of a high number of patients, the author highlights the frequency of female sexual dysfunction. The aetiology of the disease is partially known. Although diagnostical tests and therapeutical options are limited, it is essential to consider the existence and the high prevalence of female sexual dysfunction and to integrate this into our medical thinking.]

[Is a paradigm shift possible in the clinical practice of preventing recurrent fractures?]

TAKÁCS István

[Recurrent osteoporotic bone fractures are less and less considered “natural”, due to the immense variety of products available for treatment. In order to prevent recurrent fractures, treatment should be started in time, and a careful approach is needed to choose the appropriate treatment, and, if needed, to switch therapy. When choosing the therapeutic approach, we have to decide whether it corresponds to the severity of the osteoporosis and the risk of fracture. In order to do this, we have to consider bone quality, previous fractures, the condition of cortical bones and the mode of action of the selected treatment, in addition to the easily evaluated density value. The aim of this article is to provide practical help for the above mentioned decisionmaking process.]

[New antiepileptic drugs, and therapeutic considerations]

SZUPERA Zoltán

[Epilepsy is not a singular disease, but a variety of disorders. It is affects up to 0.5% of the population. Over the past decade, the researchers have been made great advances in the field of epilepsy. These have been accompanied by the licensing of a great number of antiepileptic drugs. However, despite these efforts, up to 15-20% of patients have refractory epilepsy. The novel antiepileptic drugs must suit several requirements: higher efficacy, especially in resistant cases, better tolerability, and improved pharmacokinetic properties. Recently, three new drugs have been introduced for the medication. The retigabine is a carbamic derivate, and the anticonvulsive properties are largely due to its ability to prolong the opening of neuronal voltage-gated potassium Kv7.2 and Kv7.3 channels. The lacosamide is a functionalized amino acid, and selectively enhances voltage-gated sodium channel slow inactivation. The eslicarbazepine acetate is a new member of the dibenzazepine family, and blocks the fast inactivated voltage-gated sodium channel. All three of them differ from the foregoing agents in several important ways, including new mechanism of action (retigabine, lacosamide), or pharmacokinetics (eslicarbazepine acetate). These novel anticonvulsants appears to be a safe and effective addition to the armamentarium for the treatment of patients with refractory epilepsy. However, it must take some new approaches into consideration, in the therapeutic algorithm.]

[Liver diseases and diabetes mellitus]

WINKLER Gábor

[The liver plays a pivotal role in metabolism. Thus, it is hardly surprising that its acute and chronic diseases may be accompanied by multiple disturbances of the carbohydrate metabolism, and the development of diabetes mellitus - primarily of type 2 diabetes mellitus - may result in structural changes in the liver. This article overviews the main pathogenetic mechanisms of this bidirectional relationship, discusses special considerations of choosing the therapy and highlights special difficulties of the assessment of a diabetic metabolism.]

[Erythropoiesis-stimulating agents and oxidative stress in hemodialysis patients]

MONOSTORI Péter, S. VARGA Ilona, KISS József Zoltán, KISS István, HASZON Ibolya, PAPP Ferenc, SÜMEGI Viktória, BERECZKI Csaba, NÉMETH Ilona, TÚRI Sándor

[Oxidative stress plays an important role in the elevation of the cardiovascular risk of patients with chronic kidney insufficiency. The oxidative stress becomes more severe together with the deterioration of the renal function, and the hemodialysis sessions may also induce repetitive oxidative insults. Erythropoesis-stimulating agents (ESAs) may alter the level of oxidative stress via their effects on hematopoiesis, resulting in indirect effects on changes of iron metabolism and the levels of antioxidants. We review the current knowledge about the administration of ESAs as concerns effects on oxidative parameters in hemodialysis patients. We discuss the relationship between the characteristics of the ESA therapy (type, administration frequency and dosage of ESA, length of the therapy, administration withdrawal) and the oxidative stress in view of earlier and recent research.]
