While there is a common vision of fear of the Internet being the uniting medium of millions of isolated users, many studies reveal that Internet has a growing role in interpersonal communication, spending spare-time, performing work and utilizing various services. All this raises, with good reason, the question of how the Internet affects social contacts and social capital. We have analyzed the data originating from the Hungarian panel-research (TARKI-ITTK) of the second year of the World Internet Project, and have found that using the Internet does not reduce the level of individuals' social skills. On the contrary, we have concluded that among the users and non-users hailing from the same social background (age, gender and status) the users time and time again have higher sociability indices, that, in addition, rise in line with their time spent on the net. Results are encouraging in respect of users with low social capital, as the Internet seems to enable them to increase their social networks and social capital. However, to explain these findings, we still do have to research for the right answers.

In our analysis we examine how the Internet use affects relations, and whether the network characteristics of people exert provable influences on the spread of Internet usage. The empirical basis of our longitudinal research is the three surveys done in the framework of the World Internet Project between 2001 and 2003.

This is the first report of Pasteurella multocida type B in Hungarian pigs. This disease was observed in backyard-raised pigs in three households within a small area. Neither the source of the infection nor the epidemiological connection between any of the premises could be determined. The most consistent lesion was dark red discolouration of the skin of the ventral neck and brisket, with accompanying oedema and haemorrhages. The morbidity was low and lethality relatively high, with three dead (50%) and two euthanised (33%) out of six affected animals. A total of three isolates of P. multocida (P55, P56 and P57) were cultured from these cases and examined in detail. These were identified as P. multocida ssp. multocida biovar 3. All were toxA negative and belonged to serotype B:2. Multilocus sequence typing was used to assign these to a new sequence type (ST61) that is closely related to other haemorrhagic septicaemia causing strains of P. multocida regardless of the host. M13 polymerase chain reaction and virulence-associated gene typing also show that type B strains form a highly homogeneous, distinct phylogenic group within P. multocida.

Cases of equine abortion and perinatal foal losses were investigated in Hungary during a three-year period (1998–2000). Samples from aborted equine fetuses and newborn foals (total n = 96) were examined using bacteriological, virological, pathological, immunohistochemical (IHC), molecular biological and serological methods. The cause of abortion and perinatal foal loss was identified in 67/96 cases (70%); viral infection was found in 22 (23%), viral and bacterial coinfection in 1 (1%), bacterial infection in 23 (24%), protozoan infection in 1 (1%) and fungal infection in 2 cases (2%). Morphological lesions suggestive of infection were recorded in 2 (2%) and non-infectious causes in 16 cases (17%).

Bevezetés: A primer malignus csontdaganatok kb. 30%-a chondrosarcoma, leginkább az elülső mellkasfalon jelentkeznek. Azoknak a betegeknek, akik megfelelő sebészi kezelést kapnak, 97%-os a 10 éves túlélési rátájuk. Ezenfelül fontos a terhelhetőség és a légzési funkció megőrzése, nem utolsósorban pedig az esztétikai eredmény. Beteg: A szerzők egy 44 éves férfi beteg esetét ismertetik, aki sportmasszőrként dolgozott, és a manubrium sterni Grade II chondrosarcomája miatt került műtétre. A beavatkozás során a sternum érintett része szélesen az épben kimetszésre került, a helyreállítás során a Dual Mesht bal oldali pectoralis major lebennyel fedték, valamint egyedi megoldásként a semitendinosus és -gracilis izmok inát felhasználva fixáltak két claviculát egymáshoz, ezáltal nagyfokú stabilitást adva a mellkasfalnak, és -visszaadva a felső végtag, illetve a vállöv terhelhetőségét. Eredmény: Eseménytelen posztoperatív szak után a beteg hamar felépült, és gyorsan visszatérhetett korábbi, a vállövet jelentősen igénybe vevő munkájához. Következtetés: A szerzők nem találtak hasonló műtéti eljárást az irodalomban, és ajánlják alkalmazását hasonló esetekben.
