[Minimally invasive method for the restoration of localized anterior tooth wear. A case report].

Wear localized on front teeth is quite common; the restoration of the lost tissue is generally difficult due to the lack of vertical space between the upper and lower teeth. The traditional prosthetic method would include further tooth preparation for complete crowns and for increasing the occlusal vertical dimension. By applying the Dahl concept the necessary vertical space can be created with the preservation of the tooth tissue in a relatively short period of time.

[Skeletal anchorage: use of miniscrews for impacted maxillary canine management].

Impaction of maxillary canines is a frequently encountered clinical problem. Patients' refusal to a long orthodontic treatment or ankylosis of the impacted tooth results in various treatment difficulties. The aim of this study was to evaluate the possible role of miniscrews in the management of impacted upper canines.

[Centenary of the publication of the monograph by Jenô Hillebrand entitled "New data on the morphology of human teeth"].

The dental morphological monograph by the anthropologist Jenô Hillebrand was published one hundred years ago. The book gave statistical data on 89 pages in eight chapters from the tooth collection of 4000 skulls and 2000 mandibles, as well as of 60 skulls of children. The chapters are about: onto- and phylogenesis of teeth, the size of teeth, crown-morphology, the roots of teeth, supernumerary teeth, absence of teeth, gaps (diasthema, trema), enamel hypoplasy and caries.

Surgery of benign liver tumors: indications for treatment: twenty years' experience.

Background/aims: The aim of this study is to give an audit of the experiences in the Institute of Experimental Surgery, at the University of Szeged, over the past 2 decades in the form of a retrospective study.

Methodology: Between January 1982 and December 2001, 132 patients with benign liver tumor (adenoma: 22; focal nodular hyperplasia: 27; hemangioma: 83) were treated. A total of 112 patients underwent surgery, while 20 asymptomatic cases were merely observed.

[Surgery of benign liver tumors: indications for treatment. Personal experience and review of the literature].

Background And Aims: Our aim is to give an audit of our experience over the past two decades in the form of a retrospective study.

Patients/methods: Between 1 January, 1982 and 15 December, 2001, 133 patients with benign liver tumor (adenoma: 22, focal nodular hyperplasia: 27, hemangioma: 83, lipoma: 1) were treated. A total of 113 patients underwent surgery, while 20 asymptomatic cases were merely observed.

Liver abscess caused by Stenotrophomonas maltophilia: report of a case.

We report the case of a melioidosis-like abscess of the liver caused by Stenotrophomonas (Xanthomonas) maltophilia infection in a Chinese man living in Hungary. Although this appears to be the first documentation of a liver abscess of this origin in a nonimmunocompromised patient, our case report demonstrates that this common facultative pathogen can also cause liver abscess and sepsis. After repeated negative blood cultures, histological examinations of liver biopsies suggested the possibility of chronic melioidosis, but the microbiological examination performed directly on the same specimen identified a Stenotrophomonas maltophilia infection.

Experience with different methods of treatment of nonparasitic liver cysts.

Background And Aims: In a search for the optimal management of nonparasitic liver cysts, a study was made of the effectiveness of different methods.

Patients And Methods: Between 1 January 1982 and 15 December 2001 we treated 132 patients with nonparasitic liver cysts. In 72 patients 31 cysts were treated with enucleation, 60 with deroofing, and 24 with stitching by laparotomy; two liver resections were also performed.
