Every year, there are about 192 000 square kilometres of forest less on Earth. As the distribution of tree density is not evenly distributed, it is important to express the loss in terms of tree trunks: an estimated 15.3 billion trees per year. Global soil erosion, climate change, human population growth and increasing per capita consumption all point to a further decline in the number of trees on Earth. The trend is not new: since the last ice age, human civilisation has eradicated roughly half of all forests. Mankind has needed trees or forested land in ever-increasing quantities, for varying purposes, as it has developed technologically. Timber was and is needed for firewood, for building slate castles, mills, ships or railways, and later for paper or other goods. And land was essential for agriculture and cities. Reforestation has been and is still hampered to a greater extent by the cultivation of fields and to a lesser extent by industrial production...

[Mastitis and breastfeeding]

UNGVÁRY Renáta, MIKÓ-BARÁTH Eszter, KISS Eleonóra

[Various degrees of mastitis affect a significant percentage of breastfeeding mothers. Prevention and effective treatment are important public health issues due to the severe pain, malaise, high fever, and possible complications. Among other causes for early termination of breastfeeding, the most prominent reasons are the pain, prolonged healing, abscess due to mastitis and the frequent recurrence of the disease. Proper management of mastitis and alleviating the symptoms influence the length of breastfeeding and hence leads to a positive outcome for both the mother’s and her child’s long term health. Nevertheless, there are inconsistencies worldwide regarding the diagnosis, cure and prevention of mastitis. The treatments are done mostly on empirical basis. Even though numerous articles have been published on the subject, the unequivocal results are yet to come. This overview summarizes the current knowledge and the dilemmas about mastitis as well as the prevention opportunities and therapies. It also discusses the new results on breastmilk microbiome research, which might change the approach towards mastitis treatment.]

[Modalities of the therapy of patients with high cardiovascular risk]

FARSANG Csaba

[International and Hungarian guidelines emphasize the need of the combinations in the therapy of hypertension. Single pill combinations (SPC) are preferred. The importance of the treatment reducing cardiovascular risk is underlined by the fact that in most hypertensive patients other cardiovascular risk factors, among them most frequently dyslipidemia is present. In addition to antihypertensive drugs these patients should be treated also with those decreasing plasma lipids. Adherence / persistence to therapy of patients is greatly improved by the use of single pill combinations. Today we also have SPCs decreasing both, blood pressure and plasma lipids. Among them there is the combination containing amlodipine and atorvastatin. Several international and Hungarian clinical studies have been conducted. Results of these investigations have been described in several publications. In this paper I summarise the most important results of some of these studies. ]

[Type 2 diabetes: what is the role of a General Practitioner in the treatment of diabetes?]

TORZSA Péter, OLÁH Ilona, HARGITTAY Csenge, KALABAY László

[The 2017 National Guidelines of the Hun­garian Diabetes Association emphasize the individual treatment of diabetic patients and the strong, goal-oriented regulation of carbohydrate metabolism from recogni­tion on. Beside monotherapy, primary dual or triple combination therapy may be applied in the treatment of patients. In primary care it’s the treatment of patients with type 2 diabetes where there is a lot to be done. We hope that the everyday use of the Professional Guidelines will contribute to a more successful diabetic care by General Practitioners (GPs). The holistic care of the GP’s team plays an important role in the primary, secondary and tertiary prevention of Type 2 diabetes, which accounts for more than 90% of all diabetic cases. ]

Neurocognitive aging and the associated brain diseases impose a major social and economic burden. Therefore, substantial efforts have been put into revealing the lifestyle, the neurobiological and the genetic underpinnings of healthy neurocognitive aging. However, these studies take place almost exclusively in a limited number of highly­developed countries. Thus, it is an important open

The effect of anesthetic blockade of greater occipital nerve during the withdrawal period of the medication overuse headache treatment

MIRAC Aysen UNSAL, TUGRUL AYDIN

Discontinuation of medication still remains a key element in the treatment of medication overuse headache (MOH), but there is no consensus on the withdrawal procedure. We aimed to share the promising results of anesthetic blockade of greater occipital nerve (GON), which can be an alternative to existing treatments during the early withdrawal period of MOH treatment.

[Importance of personality disorders in epilepsy]

KISS Rita-Judit, ORBÁN-KIS Károly, SZILÁGYI Tibor

[Epilepsy is one of the most common neurological disorders. Therapeutic success shows high variability between patients, at least 20-30% of the cases are drug-resistant. It can highly affect the social status, interpersonal relationships, mental health and the overall quality of life of those affected.
Although several studies can be found on the psychiatric diseases associated with epilepsy, only a few researches focus on the occurrence of personality disorders accompanying the latter. The aim of this review is to help clinicians to recognize the signs of personality disorders and to investigate their connection and interaction with epilepsy in the light of current experiences.
The researches reviewed in this study confirm that personality disorders and pathological personality traits are common in certain types of epilepsy and they affect many areas of patients’ lives. These studies draw attention to the importance of a multidisciplinary approach to this neurological disorder and to provide suggestions about the available help options. Considering the high frequency of epilepsy-related pathological personality traits that can have a great impact on the therapeutic cooperation and on the patients’ quality of life, it important that the neurologist recognizes early the signs of the patient’s psychological impairment. Thus they can get involved in organizing the support of both the patient and their environment by including psychiatrists, psychologists, social and self-help associations.
As interdisciplinary studies show, epilepsy is a complex disease and besides trying to treat the seizures, it is also important to manage the patient’s psychological and social situation. Cooperation, treatment response and quality of life altogether can be significantly improved if our focus is on guiding the patient through the possibilities of assistance by seeing the complexity and the difficulties of their situation.]

[Female specific differences of ischemic stroke and cerebral venous thrombosis]

VASTAGH Ildikó, BERECZKI Dániel

[There are female-specific characteristics also in epidemiology, emerging risk factors, acute reperfusion therapy and out­come of cerebrovascular disorders. Among classical risk factors, as hypertension, atrial fibrillation, diabetes and obesity the risk of stroke is higher in females than males. Re­cognizing female specific risk factors is indispensable not only in therapeutic but also in preventive measures. Pregnancy and puerperium increase the prothrom­botic state which results in a significantly higher incidence of ischemic stroke and cerebral venous thrombosis respectively. The treatment of acute stroke in pregnancy and puerperium is a great challenge since the concerning guidelines providing hardly any conduct in such cases. After meno­pause, there is change in prevalence and severity of cardiovascular risk factors and as a result, the stroke incidence is higher among females than males over the age of 80. Additionally, there are evidence based sex differences in the stroke outcomes. This re­view aims to improve the stroke care quality by presenting characteristic sex differences in this summary. ]

[Clinical features of familial hypercholesterolemia patients in Hungary’s Northern Great Plain region – significance of the familial hypercholesterolemia registry ]

SZÔKE Csenge, ZSÍROS Noémi, LÔRINCZ Hajnalka, PARAGH György, HARANGI Mariann

[Familial hypercholesterolemia (FH) is an inherited metabolic disorder associated with elevated total cholesterol and LDL-C levels and early cardiovascular complications. Recognizing and identification of additional risk factors, and the early, efficient lipid-lowering treatment is of pre-eminent importance. Thus, we aimed to evaluate specific regional data of the FH registry in Hungary.

We collected anamnestic data, results of physical examinations, laboratory parameters and achieved lipid values after the lipid lowering treatment of 192 FH patients. While diagnosing FH, we applied the Dutch Lipid Clinic Network criteria. 

We enrolled 140 females and 52 males with average mean age 49.4 ± 15.7 ys and mean BMI 25.8 ± 4.5 kg/m2. They had in 38.5% hypertension, 2.1% type-2 diabetes and 12% smoked tobacco. At diagnosing, the initial total cholesterol was 8.92 ± 2.71 mmol/L and the LDL-C was 6.04 ± 1.9 mmol/L. Genetic tests supported the diagnosis of FH in 53 cases (27.6%). 110 patients (57.3%) were treated with statin, 80 (41.7%) with ezetimibe, and 26 (13,5%) with PCSK9 inhibitors. 45 patients (23.4%) had definitive statin intolerance. Achieved total cholesterol after lipid lowering treatment was 5.86 ± 2.15 mmol/L (–34.3%), while LDL-C was 3.42 ± 1.69 (–43.4%) mmol/L

Number of registered FH patients was markedly lower than estimated by the prevalence data. Due to the high frequency of statin intolerance and partly by omitted administration of effec­tive lipid lowering medication for cost curbing reasons the lipid level goals did not succeed.
