[MYCOSES IN PATIENTS WITH HAEMATOLOGICAL MALIGNANCIES AND STEM CELL TRANSPLANTATION]

PRINZ Gyula, SINKÓ János, NIKOLOVA Radka

[Patients with haematological malignancies and stem cell transplantation are frequently prone to develop invasive mycoses. Candida and Aspergillus are the major fungal pathogens that cause infections. The recently introduced new antifungal agents, voriconazole and caspofungin and new diagnostic methods changed the treatment strategies of invasive mycoses. The authors give an overview of the diagnostics, prophylaxis and treatment of the clinically important fungal infections.]

Neuroscience highlights: Main cell types underlying memory and spatial navigation

KRABOTH Zoltán, KÁLMÁN Bernadette

Interest in the hippocampal formation and its role in navigation and memory arose in the second part of the 20th century, at least in part due to the curious case of Henry G. Molaison, who underwent brain surgery for intractable epilepsy. The temporal association observed between the removal of his entorhinal cortex along with a significant part of hippocampus and the developing severe memory deficit inspired scientists to focus on these regions. The subsequent discovery of the so-called place cells in the hippocampus launched the description of many other functional cell types and neuronal networks throughout the Papez-circuit that has a key role in memory processes and spatial information coding (speed, head direction, border, grid, object-vector etc). Each of these cell types has its own unique characteristics, and together they form the so-called “Brain GPS”. The aim of this short survey is to highlight for practicing neurologists the types of cells and neuronal networks that represent the anatomical substrates and physiological correlates of pathological entities affecting the limbic system, especially in the temporal lobe. For that purpose, we survey early discoveries along with the most relevant neuroscience observations from the recent literature. By this brief survey, we highlight main cell types in the hippocampal formation, and describe their roles in spatial navigation and memory processes. In recent decades, an array of new and functionally unique neuron types has been recognized in the hippocampal formation, but likely more remain to be discovered. For a better understanding of the heterogeneous presentations of neurological disorders affecting this anatomical region, insights into the constantly evolving neuroscience behind may be helpful. The public health consequences of diseases that affect memory and spatial navigation are high, and grow as the population ages, prompting scientist to focus on further exploring this brain region.

Purpose - Methylation is a key epigenetic modification of DNA and regarding its impact on epilepsy, it is argued that “DNA methylation may play an important role in seizure susceptibility and maintenance of the disorder”. DNA methylation status of KCC2 (SCL12A5) and NKCC1 (SCL12A2) associated with refractory temporal lobe epilepsy was investigated in our study. Materials and methods - Thirty-eight patients with temporal lobe epilepsy (TLE) who were diagnosed by video EEG monitoring and 32 healthy control subjects were included in the study. Twenty-three patients in TLE group were men and the remaining 15 were women. Among them, 27 had unilateral temporal focus (9 with right; 18 with left) and 11 patients had bilateral TLE. We analyzed promoter region methylation status of the KCC2 (SCL12A5) and NKCC1 (SCL12A2) genes in the case and control groups. Gene regions of interest were amplified through PCR and sequencing was accomplished with pyro-sequencing. Results - We found a significant relationship between TLE and methylation on the NKCC1. However, there was no association between TLE and methylation on the KCC2 gene. Also, we found no association between right or left and unilateral or bilateral foci of TLE. There was no relationship between TLE and methylation on the NKCC1and KCC2 genes in terms of mesial temporal sclerosis in cranial MRI, head trauma or febrile convulsions. Conclusion - The methylation of NKCC1 can be a mecha­nism of refractory temporal lobe epilepsy. There are limited findings about DNA methylation in TLE. Therefore, further studies with large sample sizes are necessary.

[Family planning in multiple sclerosis: conception, pregnancy, breastfeeding]

RÓZSA Csilla

[Family planning is an exceptionally important question in multiple sclerosis, as women of childbearing age are the ones most often affected. Although it is proven that pregnancy does not worsen the long-term prognosis of relapsing-remitting multiple sclerosis, many patients are still doubtful about having children. This question is further complicated by the fact that patients – and often even doctors – are not sufficiently informed about how the ever-increasing number of available disease-modifying treatments affect pregnancies. Breastfeeding is an even less clear topic. Patients usually look to their neurologists first for answers concerning these matters. It falls to the neurologist to rationally evaluate the risks and benefits of contraception, pregnancy, assisted reproduction, childbirth, breastfeeding and disease modifying treatments, to inform patients about these, and then together come to a decision about the best possible therapeutic approach, taking the patients’ individual family plans into consideration. Here we present a review of relevant literature adhering to international guidelines on the topics of conception, pregnancy and breastfeeding, with a special focus on the applicability of approved disease modifying treatments during pregnancy and breastfeeding. The goal of this article is to provide clinicians involved in the care of MS patients with up-to-date information that they can utilize in their day-to-day clinical practice. ]

[The liaison between internal medicine and psychiatry can be life-saving in the treatment of severe anorexia nervosa]

SZÉNYEI Gábor, BENE László, TÚRY Ferenc

[INTRODUCTION - In the severe forms of anorexia nervosa hospitalization may be required, and the somatic treatment is provided in a department of internal medicine. In such cases, collaboration between internist and psychiatrist is essential. Psycho­logical support is necessary even in the period of nutritional rehabilitation. This can be applied in the framework of consultation-liaison psychiatry. After the initial weight gain providing psychotherapy in an outpatient setting is fundamental. In the case of anorexic patients who maintain a close relationship with the family, family therapy is the most effective treatment. CASE REPORT - A 26-year old female patient with anorexia was hospitalized in a department of internal medicine after an extreme emaciation, her body mass index was 11.6. During this period there was a psychiatric consultation involving the fa-ther of the patient as well. Her body weight increased, and outpatient family therapy was initiated. Fifteen family sessions were conducted in nine months, with special focus on the separation-individuation process. At the end of the therapy a full remission could be observed, with a normal body weight, and her periods returned. After a four-month follow-up her state was stable, and she got married. CONCLUSION - Interdisciplinary collaboration can be cardinal when somatic and psychological disorders are interwoven. The role of family therapy is crucial in those cases where emotional separation from the family of origin is difficult, even if the patient does not live with the parents any longer. ]
