[Ayahuasca, which originates from the Amazon Basin, is a psychoactive brew of two components. Its active agents are betacarboline and tryptamine derivatives. Near the spring of the Amazon River this brew is still a central component of many healing and tribal rituals. During the past few decades, the substance has become known among both laymen and scientistss and nowadays its use is spreading all over in Europe. In the present paper we give an overview of the scientific research and describe ayahuasca's main features, the main questions raised over its use, the risk factors and potential benefits. A growing number of scientific results seem to support the psychotherapeutic potential of ayahuasca, which has a strong serotonergic effect, whereas studies on its effect on the immune system also raise the possibility that certain ethno-medical observations can be scientifically proved.]

[Hypertension in the elderly - critical review of diagnostic-therapeutic guidelines and their background]

SZÉKÁCS Béla

[In the majority of old and very old hypertensive patients, the reduction of abnormally high blood pressure has been proved to provide a strategic defense of target organs. In patients younger than 80 years, both initial and target blood pressure (BP) values are similar to those of younger age groups. In those older than 80 years, a a systolic blood pressure level >160 mmHg is the threshold of indication for antihypertensive treatment and the therapeutic target value is<150 mmHg. Both values are evidence- based (HYVET). The latest ACCF/AHA guidelines (USA 2011) advise to achieve a BP below 140 mmHg if the use of one or two antihypertensive agents result in sufficient BP reduction. However, this strategy is not yet supported by unequivocal evidence regarding complications in target organs. It is not recommended to aim for target levels lower than the above values (especially the value defined by the ESH guidelines) even in elderly hypertensive patients at high cardiovascular risk, as the results of several studies suggest a J-curve effect. In multimorbid elderly patients it is highly important to adapt antihypertensive treatment to individual needs, rather than to use schematic approaches. The number and progression of comorbid diseases can greatly influence, in certain cases attenuate the aimed BP reduction. A similar medical decision should be made if the target BP level could only be achieved by the combination of multiple antihypertensive medications, which can remarkably impair quality of life in elderly patients. Among non-comorbid elderly patients with hypertension, there seems to be no convincing difference in the efficiency of target organ protection between antihypertensive treatments that have different target sites but can achieve similar target levels. However, the majority of elderly hypertensive patients have comorbidities with variable rates of progression. In those at even low cardiometabolic risk the use of beta-receptor blockers (BRB) and especially a combination of BRB+diuretic (DIU) is not recommended. The adequate therapeutic tactic includes the use of only moderate drug-doses and their early combination. This approach has been convincingly proved mainly with early combinations of RAS inhibitors+CCB-s and RAS inhibitors+small doses of DIU-s. It is very important to monitor the treated patients, as the BP and circulatory response to the same antihypertensive treatment can markedly change in elderly patients when either the enviromental conditions change or a new pathologic process develops and/or is treated. Strict control is also necessary because it occurs quite often that the earlier optimal compliance of elderly patients in taking antihypertensive medicines rapidly deteriorates. The efficiency of statins and acetylsalicylic acid decreases over 80 years of age, but this does not indicate that the previously efficient approach should be suspended.]

[Rosuvastatin for the treatment of diabetic dyslipidaemia]

SIMONYI Gábor

[Cardiovascular disease is a leading cause of death. The incidence of type 2 diabetes is increasing worldwide as well as in Hungary. Diabetes mellitus is a high-risk state, and if associated with coronary disease, it is considered a very high-risk condition. According to the 5th Cardiovascular Consensus Conference and ESC/EAS, the target level of LDL-cholesterol should be <2.5 mmol/l in high-risk condition and <1.8 mmol/l in very high-risk condition. In diabetes, one of the main goals is to achieve target LDL-cholesterol levels, which require lifestyle changes as a first step, followed by statin treatment, in combination with with ezetimibe if necessary. Statins are also known to have diabetogenic effects, which are dose-dependent. The advantage of the preventive cardiovascular effects observed in nondiabetic patients substantially outweighs the risk of potentially developing diabetes mellitus, therefore, this risk should not hinder the use of statins. Statin treatment can substantially reduce cardiovascular events in patients with diabetes mellitus. The greatest reduction in LDL-cholesterol level can be achieved by the most efficient statin, rosuvastatin.]

[The relationship of traumatic experiences and eating disorders – therapeutical options]

KOVÁCS-TÓTH Beáta, TÚRY Ferenc

[In the etiology of eating disorders (espe­cially bulimia nervosa and binge eating) traumatic experiences (sexual, physical, emo­tional abuse, neglect) play an important role. Traumatization can have a serious impact, which is influenced by the parameters of the traumatization, risk and protective factors, and the resiliency of the traumatized patient. The consequences may lead to the development of specific psychiatric and somatic disorders, and may cause lifetime revictimization. The exploration of data related to the traumatization is essential in eating disorders as well. If traumatic expericences can be detected in the back­ground of eating disorders, the targeted therapy of eating disorders while applying its specific elements should also follow the guide­lines of the general trauma-therapy. Providing safety in therapeutical relation­ship is fundamental. The therapeutic options are extensive. Along with psychodynamically oriented therapies, the newer methods based on cognitive-behavioral therapy (e.g., dialectic behavior therapy, integrative cognitive analytic therapy) are also proposed. Hyp­no­therapy can also be useful. ]

[The role of spirituality in the twelve-step treatment model of addicts]

TREMKÓ Mariann, TÓTH András, MOLNÁR Rudolf, PETKE Zsolt

[First of all we shortly present the Minnesota model based on twelve-step programmes that could be implemented effectively in the recovery of addicts. The uniqueness of the model are the involvement of recovering helpers in the therapeutic work and the focus on spirituality. Our essay-like study aims to present the approach of Alcoholics Anonymous which forms the basis of the model, effectivity studies and the potential effect mechanisms through research data. We aim to define the phenomenon of spirituality from different aspects having regard to the preliminary psychological and psychotherapeutical contributions and provide some of our therapeutic tools. In the current study we picture the roles of the professional therapists and the voluntary recovering helpers in our programme. ]

[Why is it important and ethical to treat anxiety patients?]

RADICS Judit

[The identification of anxious patiens is not always an easy task. The diagnose is clear in that case, when the symptoms (psychic or somatic) are evident or/and patients complain about anxiety. Anxiety itself is not a pathological symptom if it is adequate in strength and duration. Anxiety reactions have large individual variety -, they are pathological if inadequate and irrelevante and don’t match with the actual situation. According to epidemilogical data one third of patients of family doctors suffer from anxiety but somatic symptoms come to the front, so the patients participate in a great number of medical examinations. It is important to emphasise that medical examinations are necessary to preclude the possibility of any somatic disease. The di­ag­nostic criteria of DSM-5. are an excellent assistance for a good diagnosis. Anxiety is a risk factor for cardiological diseases and diabetes mellitus. The prevalence of anxiety disorders are 12.6-17.2%. Anxiety di­sorders are well-manageable, they need complex therapy: benzodiazepines, antidepressants, hypnotics and psychotherapy. They frequently co-exist with depression and insomnia so they have to be treated together. ]

[History of Daytime Hospital of the Department of Psychiatry in the University of Debrecen ]

ÉGERHÁZI Anikó, CSERÉP Edina, MAGYAR Erzsébet

[In Hungary, there was a ward related psychotherapy already since the 1960s, yet without any national network to the 1980s. In Debrecen the spreading of the psychotherapeutic approach started in the psychiatric facilities since the 1990s. Daytime Hospital was founded first in the County Hospital and later on in the Department of Psychiatry of the University. The latter option was provided by separating the psychiatry from neurology. This study presents the development of the day care at the Psychiatric Department along the opportunities and shows the structure of the actually functioning system finally reports on our future plans respectively. Initially started the occupational therapy, gymnastics, community cooking and walking, which did not require any separate rooms. The 22-bed psychotherapeutic unit was established 2014 with its joined capacity for 11 persons in the Daytime Hospital. The County Hospital is engaged primarily in socio-therapy of psychotic psychiatry pa­tients, however the Psychiatric Department is rehabilitating mainly patients with affective spectrum disorders. Patients are treated in socio-therapy and psychotherapy small groups for a half or one year. Afterward they enter the outpatient program, may join the Patient Club or decide for therapeutic occupation aiming the best way of recovery. According to the feedback, there is a long-term change in the mental state of the patients leading to improvement in their quality of life, which we plan to prove by an efficacy research program. ]

[Neoadjuvant therapy in breast cancer – an update]

KAHÁN Zsuzsanna, RUSZ Orsolya, UHERCSÁK Gabriella, NIKOLÉNYI Alíz

[Traditionally, neoadjuvant systemic therapy (NST) serves as treatment of advanced breast cancer to achieve technical operability by resulting in tumor regression. Nowadays, NST is advantageous in all cases if adjuvant systemic therapy is needed, since the in vivo study of its effect provides possibility for the estimation of prognosis, the treatment may be modifi ed according to the therapeutic response, the systemic therapy starts earlier as compared to adjuvant therapy, and fi nally, it may result in the reduction of surgical and radiotherapeutical radicality. The type of NST should be selected on the basis of tumor features refl ecting treatment sensitivity. In case of chemosensitive cancers, chemotherapy is taxane- and anthracycline-based, and the planned dose should be delivered prior to surgery. In HER2-positive cancers, the addition of an anti-HER2 agent doubles the rate of pathological complete regressions. In hormone-sensitive tumors, the standard neoadjuvant endocrine therapy consists of an aromatase inhibitor (postmenopause), or tamoxifen or an aromatase inhibitor combined with an LHRH analog (premenopause) for 4-8 months that is continued following the surgery in the adjuvant setting. For the early evaluation of the effect of NST, serial tumor biopsy or imaging studies (MRI, PET) seem promising. Sentinel lymph node biopsy around the NST should be practiced with prudence; it may warrant the avoidance of axillary blockdissection in some cases. For the design of radiotherapy, the initial stage and the degree of regression are considered.]
