[INTRODUCTION - Congenital clubfoot is a severe developmental disorder. Without treatment, only the lateral border of the foot can be loaded and the sole faces the contralateral side. Good results can usually be achieved with early redression by serial casting (generally from the first week after birth) followed by extensive surgery at age six months (Achilles tendon lengthening, capsulotomy of the talo-crural and subtalar joints). The above procedure has been revolutionised by the method described by Ignacio Ponseti based on his own experiences, which has modified the casting technique and has also radically changed the surgical intervention. In this paper we report our experiences with Ponseti’s method and draw attention to this less invasive procedure. PATIENTS AND METHODS -The essence of Ponseti’s techniqe is reposition of the talonavicular joint, for which the foot is corrected in a different way compared with previous practice. Following redression for 8-10 weeks, percutaneous complete Achilles tenotomy is performed and the foot is fixed for further three weeks. A special orthesis is worn in the following 6 months for 24 hours a day and the same ortézis is suggested for overnights afterwards. In our institution, 171 clubfeet (45 unilateral, 126 bilateral; 84 right, 87 left; 25 girls, 83 boys) were treated between 2007 and 2012. Our results were evaluated with the help of the Pirani score, which is a widely used method for assessment of clubfoot treatment. RESULTS - Results were evaluated at the beginning of the treatment, at the end of redression and after percutaneous Achilles tenotomy. Pirani scores were 4.54±1.30; 1.48±1.02 and 0.59±0.45 respectively. The average dorsal flexion of the ankle joints was 23±12 degrees. CONCLUSION - Our own observations support the good results published in the literature, therefore the less invasive Ponseti method is suggested for the primary treatment of congenital clubfoot.]

[Role of β-blockers, especially carvedilol in the treatment of hypertension]

PÁLL Dénes, MARODA László, ZRÍNYI Miklós

[Changes in hypertension guidelines in the past years have affected the clinical thinking about β-blockers. Authors reviewed the development of β-blockers emphasizing the differences across various active pharmaceutical agents. Different hemodynamic and metabolic effects are being discussed in details for the third ge - neration vasodilatator carvedilol. Carvedilol has no effect on cardiac output but decreases peripheral vascular resistance which results in lower blood pressure values. However, carvedilol, opposite to unfavorable effects of traditional β-blockers, has a neutral impact on both carbohydrate and lipid metabolisms. Its more advanced cardiac effects include decreased left ventricular hypertrophy and increased coronary flow reserve. Vasodilatator type β-blockers (carvedilol, nebivolol) are indicated in the combi - nation treatment of hypertension, especially when the patient has heart failure, coronary disease or suffered from a previous heart attack.]

[Novelties in the management of Hodgkin lymphoma]

ILLÉS Árpád, MOLNÁR Zsuzsa, MILTÉNYI Zsófia

[Hodgkin lymphoma is a lymphoproliferativ disease, it is about 12-18% of all lymphomas. It has typical morphologic, clinical and therapeutic features, which can distinguish from other lymphoma types. Due to risk- and PET/CT adapted treatment Hodgkin lymphoma is a curable lymphoma with an 80-90% long-term survival, however, refracter- and relapsed patients’ therapy is a great challange. Cure rate can increase due to the development of the diagnostic and treatment modalities, but the use of standard recommendation is necessary. The aim of this review is to show new WHO 2016 lymphoma classifi cation, role of the new diagnostic options, especially 18FDG-PET/CT, Lugano classifi cation and fi rst-line and salvage therapeutic possibilities and to introduce the immunotherapy, like brentuximab vedotin and PD1 inhibitors. Certain points of hemopoietic stem cell transplantation will be also covered.]

[VITAMIN D TREATMENT: HORMONE THERAPY FOR PATIENTS WHO NEED IT OR SIMPLY A SUPPLEMENTATION FOR EVERYONE?]

SPEER Gábor

[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 (IOM), the target vitamin D level is 20 ng/ml, whereas the Endocrine Society (ES) recommends 30 ng/m as the miminum target value. According to the ES, a 1 ng/ml increase of vitamin D level can be reached by a daily intake of 100 NE, while the IOM recommends 3.6 ng/ml. Moreover, the IOM states that the effect of therapy on serum level is nonlinear. These differences show that the ES and IOM have different views on the risk of adverse effects. The IOM recommends 400 IU vitamin D daily for children younger than 1 year, 800 IU for those above 70 years and 600 IU/per day for everyone else. The ES recommend 400-1000 IU daily for all infants and 1500- 2000 IU for adults. Screening, however, is not recommended by either society. To decrease uncertainty concerning the side effects of higher-dose vitamin D treatment, it is important to understand, use and support the function of the pharmacovigilance system of the pharmaceutical industry that manufactures and markets various (prescription, over-the-counter) preparations. This is what the author aims to highlight in the second part of this article. Using this system, both the doctor and the patient can help support and accept the justification of higher-dose vitamin D therapy.]

[Bacterial contamination and irritable bowel syndrome]

NOVÁK János

[Irritable bowel syndrome (IBS) is one of the most common gastrointestinal condition, which affects 10-15% of adults in developed countries. Recent observations have raised the possibility that disturbances in the gut microbiota and/or the accompanying low-grade inflammatory state might contribute to the etiology and symptomatology of irritable bowel syndrome. Some studies indicate that small intestinal bacterial overgrowth (SIBO), as confirmed by hydrogen breath tests (HBT), is more prevalent in patients with irritable bowel syndrome than in matched controls without IBS. Although the data are conflicting, this observation has led to the hypothesis that bacterial contamination was the primary cause of IBS. As a consequence of this hypothesis, a lot of therapeutic options have found their way into the armamentarium of those who treat patients with IBS. These agents include probiotics, prebiotics, antibiotics and anti-inflammatory agents. This paper describes the various mechanisms by which changes in the gut flora might contribute to IBS and also discusses the efficacy and safety of antibiotic therapies, especially rifaximin, for treating IBS/SIBO symptoms.]

[The importance of recognition and proper treatment of hypertension and the maintenance of adherence in hypertension care]

NEMCSIK János, PÁLL Dénes, JÁRAI Zoltán

[Hypertension is the leading cause of death and disability-adjusted life years. In the United States hypertension accounts for more cardiovascular (CV) deaths than any other modifiable CV disease risk factor and was second only to cigarette smoking as a preventable cause of death for any reason. In our country the situation is similar. In Hungary the number of subjects with hypertension is approximately 3.5 million and this high prevalence contributes markedly to the poor Hungarian CV morbidity and mortality figures. The recognition of hypertension, the initiation of drug therapy and the long-term follow- up of the patients is mainly the task of primary care. Besides that it inheres high responsibility, this is also a grateful commitment, as hypertension in most of the cases can be treated properly with lifestyle-changes and medications leading to a marked decrease of CV complications, especially stroke. In our review article we would like to focus on the high prevalence of hypertension worldwide as well as in our country, the exact implementation of screening, the risk reduction potential of the proper treatment and the importance of the long-term maintenance of treatment adherence.]
