For the public, indoor radon is the main source of exposure from ionizing radiation. Radon gas originates from the radioactive decay chain of uranium deposited in rocks or in building materials. In the reviews mostly a rather steady radon exhalation has been assumed. In a village of North-East Hungary, however, high radon concentrations have been measured, differing strongly in neighbouring houses and varying in time, due to the interplay of several geochemical phenomena.

Our aims were to evaluate the primary and clinical evisceration indications and to analyse orbital implant related complications.
We included in our retrospective review all eviscerations between 2006 and 2016 at the Department of Ophthalmology of Semmelweis University, Budapest, Hungary. Primary evisceration indications were classified into six groups: trauma, surgical diseases, infections or inflammations, systemic diseases, tumours and unclassifiable diseases. Clinical immediate evisceration indications were also classified into six groups: painful blind eye due to glaucoma, atrophia/phthisis bulbi, endophthalmitis, cosmetic reasons, acute trauma and expulsive bleeding.
Evisceration was performed in 46 eyes of 46 patients (54.3% males, age 43.0 ± 18.6 years). The most common primary evisceration indications were trauma (37%), surgical diseases (34.8%), infection or inflammation (10.9%), systemic diseases (6.5%), tumours (8.7%) and unclassifiable diseases (2.2%). Painful blind eye due to glaucoma (34.8%) was the most common clinical indication for evisceration, followed by atrophia/phthisis bulbi (26.1%), endophthalmitis (17.4%), cosmetic reasons (13.0%), acute trauma (6.5%) and expulsive bleeding (2.2%). After evisceration, 91.3% of the patients received orbital implant and during 26.8±28.9 months follow-up implant related complications were found in 14.3% of the cases, including implant extrusion (4.8%), partial wound dehiscence (4.8%), implant exposure (2.4%) and orbital inflammation (2.4%).
Painful blind eye and atrophia/phthisis bulbi due to ocular trauma and surgical diseases represent the most common indications for ocular evisceration. If malignant intraocular tumours can be excluded, evisceration surgery combined with a silicon-based orbital implant is a safe and effective procedure.

Hepatocellular carcinoma, which has developed in liver cirrhosis is a disease where liver transplantation can provide a cure both for the tumour and the underlying liver damage. However, patients can only be transplanted when the tumour number and size do not exceed the Milan criteria. Tumour ablation methods — such as radiofrequency ablation — can provide a chance to make the patient eligible for transplantation. Among the 416 Hungarian liver transplanted patients there are 6 who had received different types of ablative therapy as bridging therapy in different institutions. On the basis of analysis of the patients' data we created a guideline for the treatment of cirrhotic patients with hepatocellular carcinoma with the aim of developing a uniform Hungarian approach.

The addition of synthetic (E)-anethol to the known attractant phenylacetaldehyde synergized attraction of the cotton bollworm Helicoverpa armigera, the blend invariably catching 4 to 6 times more than phenylacetaldehyde on its own. Highest catches were recorded by the 1:1-3:1 blends. The addition of salicyl aldehyde, ±linalool, (R)-(+)-limonene, 2-methoxybenzyl alcohol and 4-methoxybenzyl alcohol (compounds described earlier in the literature as co-attractants for H. armigera), increased catches when added to phenylacetaldehyde. However, the addition of these compounds did not increase catches of the (E)-anethol+pheny- lacetaldehyde blend. When directly compared with performance of the synthetic pheromone, the (E)-anethol +phenylacetaldehyde blend caught an average of 27% of the catch in pheromone baited traps. On an average 79% of moths caught in traps with the (E)-anethol+phenylacetaldehyde blend were females, while traps with pheromone caught only males. The (E)-anethol+phenylacetaldehyde blend described in this study may form the basis for the development of an efficient bisexual lure for H. armigera AFTER further optimization.

The first version of the map of the Hungarian vegetation-based landscape regions were prepared at the scale of 1: 200,000 (1 km or higher resolution). The primary goal of the map was to provide an exact background for the presentation and evaluation of the data of the MÉTA database. Secondly, we intended to give an up-to-date and detailed vegetation-based division of Hungary with a comprehensive nomenclature of the regions. Regions were primarily defined on the basis of their present zonal vegetation, or their dominant extrazonal or edaphic vegetation. Where this was not possible, abiotic factors that influence the potential vegetation, the flora were taken into consideration, thus, political and economical factors were ignored. All region borders were defined by local expert botanists, mainly based on their field knowledge. The map differs in many features from the currently used, country-wide, flora-or geography-based divisions in many features. We consider our map to be temporary (i.e. a work map), and we plan to refine and improve it after 5 years of testing.
