[Distractios osteogenesis in maxillofacial surgery].

For more than one decade the extremity surgery already used distraction osteogenesis. This new therapy in the region of the maxillofacial surgery (in the case of malformation of the maxilla and mandible) was adapted from the extremity surgeons. The authors summarized and classified the methods and history of the osteodistraction surgery based on literature.

Vegetative reproduction and chemical control with post-emergent herbicides of field bindweed (Convolvulus arvensis L.).

It is clearly seen from data that roots of Convolvulus arvensis L. have more and less intensive regenerative period during growing season. The more intensive period is in autumn, because in that time roots culminate nutrients, carbohydrate as starch and sugar.

Weed control in sunflower (helianthus annuus L.) with post-emergent herbicides.

Sunflower is the most important oil crop in Hungary, is the base of the production of cooking oil and moreover takes an important part in production of margarine too. Extracted sunflower groats as a secondary product origining from the mentioned procedure can be used in forage successfully. The amount of harvested sunflower reaches the 20-25% of the EU's yield.

Efficacy and tolerability of diclofenac potassium sachets in acute postoperative dental pain: a placebo-controlled, randomised, comparative study vs. diclofenac potassium tablets.

This double-blind, randomised, parallel-group trial compared the analgesic efficacy of single 50 mg doses of diclofenac potassium sachets and tablets with placebo in 184 patients with moderate/severe pain after third molar extraction. The primary efficacy variable was the average pain reduction from baseline during the first 2-h postdose, using a visual analogue scale (VAS). During the first 2-h postdose, sachets and tablets significantly reduced pain (p < 0.

[Gardner-syndrome: case report].

The major symptoms of Gardner-syndrome are described by the authors (multiple osteomas, desmoid tumors, colon polyps with malignant tendency) with a case appearing in their department. The importance of early diagnosis is also emphasized.

[Intra-arterial administration of Dalacin C phosphate (clindamycin) in the therapy of osteomyelitis of the jaws].

In 8 cases of maxillary and mandibular osteomyelitis which had failed to respond to traditional surgical and medicinal methods of treatment, a significant improvement could be achieved (in 7 of the 8 cases) by applying an intra-arterial clindamycin therapy. Treatment was carried out similar to the intra-arterial cytostatic perfusion treatment of tumors in the head and neck areas. Clindamycin was administered in daily dosages of 900 mg over a period of 8-23 days.

[Selection of the method of surgical approach in plate osteosynthesis of mandibular fractures].

Background: Plateosteosynthesis by intraoral approach of mandibular fractures gives the best cosmetical result but presents a rather difficult procedure.

Aims: Comparison of intra- versus extraoral approach in plateosteosynthesis of mandibular fractures.

Methods: Plate type, experience of the surgeon, age and sex of the patient, as well as hospital stay and rate of the septic complications were analysed retrospectively in 248 patients of the OMF Department (University Freiburg) with mandibular fractures with respect in view of the operative approach used.

[The role of dalacin C in the management of odontogenic inflammations].

The penicillin-metronidazole combination is well tried antibiotic therapy for the treatment of inflammations of dental origin. However, because of the rising number of penicillin-resistant bacterium strains and penicillin allergies, other antibiotics too are being applied ever more frequently. The literature data and the authors' own experience indicate that clindamycin (Dalacin C) may be used effectively against mixed infections of the oral cavity.

[Experience with Otten's maxillomandibular fixation method].

The authors are reporting on a method of mandibulomaxillary fixation worked out in their institute through a modification of those defined in literature. A wire hook is fixed by a screw to the mandibula and maxilla and, by the help of it an intermaxillary fixation is formed. The procedure is simple, quickly accomplishable and cheap.

[Malignant tumor developing in transplanted tissue in the oral cavity (case report)].

Primary and metastatic malignant tumors appears frequently in the head and neck region. The occurrence of malignancies in tissues--transplanted to this area--are extraordinary rare. Authors report about a case, where the tumor developed in a cylindroid jump flap, used to the closure of the cleft palate.

[Long-term studies after intra-arterial cytostatic therapy of head and neck tumors].

This study on selected tumour patients demonstrates relationship between the effectiveness of preoperative, postoperative and palliative intra-arterial cytostatic treatment of tumours of the head and neck and the long-term survival. During the period ranging between 3.5 and 9 years after preoperative treatment of 11 cases, palliative treatment of 6 cases, resulting in 100% tumour regression, and postoperative-adjuvant treatment of 23 cases (selected from 254 cases receiving intra-arterial treatment), local recurrence was observed in 10 cases.
