Helicobacter pylori(H. pylori) has been associated with the cause of peptic ulcer and gastric cancer. H. pylori infection occur mostly during childhood and increase by aging. In route of transmission, Oral cavity does important role. So we employed this study to elucidate route of transmission by detection of H. pylori in infant saliva. We investigated 20 infants aged below 10 years and 20 teens aged below 20 years as study group and 71 adults aged 20 and over years as control group. H. pylori DNA was isolated from 5(25%) infants aged below 10 years, 6(30%) teens and 17(23.9%) adults by nested polymerase chain reaction(n-PCR). There was no statistically significant difference(P>0.05). The obtained results suggest that H. pylori infection is relatively common in saliva of Korean infant and oral cavity may be reservoir of H. pylori.

For injuries that result from high-energy forces, particularly those in which soft tissue and large segments of bone have been lost and there is some degree of vascular compromise, the reconstruction problem is major and more complex. In such cases local muscle coverage is probably not successful, because adjacent muscles are destroyed much more than one can initially envisage. Coverage of the soft tissue loss in the sole is particularly difficult because of the forces of weight bearing on the reconstruction. Reconstruction of the lower extremity has traditionally been planned by dividing the lower leg into three parts. The flaps available in each of the three parts are gastrocnemius flap for proximal third, soleus flap for middle third, and free tissue transfer for the lower third. Over the past 4 years, from Feb. 1991 to Mar. 1995, we have used 53 free flap transfers in 48 patients to reconstruct the soft tissue defects of the lower extremity. The free flaps were executed successfully in 50 cases(94.3%). From analysis of the cases, the results are as follows 1. For the reconstruction of the lower extremity, free tissue transfer yields a more esthetic and functional result. 2. When there is bone exposure or vascular compromise, free muscle flap is usable, but its excessive bulkiness is the weak point. 3. If free muscle flap is required for the reconstruction of the lower extremity : rectus abdominis muscle for small defect and latissimus dorsi muscle for large defect are good donors. 4. If skin free flap is required in the foot, scapular flap is one of the best donors. 5. In cases where free muscle flap was used, about half of patients(43.7%) needed reoperation owing to flap bulkiness. 6. If defects were large on the sole, scapular free flap was used.

We studied about 106 cases of mandible fracture patients from May. 1990 to April. 1994, who had treated at chungnam national university plastic surgery department. They are divided into two groups by treatment methods which are compared by, with intermaxillary fixation(IMF) vs. without IMF. There was no statistically significant difference in the complications between the two groups. Rigid internal fixation(RIF) without intermaxillary fixation(IMF) generally results in greater patient satisfaction because of decreased postoperative discomfort, earlier return to normal jaw function, easier maintenance of oral hygiene, and better nutrition. So, we concluded that RIF without IMF was considerable method for indicated patients. Indication( by authors' experiences) : 1. simple fractures without severe displacement 2. favorable fractures 3. no problem about occlusion 4. well cooperative patients

As traffic vehicles are developed, it is a trend to increase in number and severity of traffic accidents. Therefore, we need the more accurate diagnosis, grouping and treatment in facial bone injuries including mandible fracture. This retrospective study evaluated the data pertaining 126 patients managed at department of plastic and reconstructive surgery, Chungnam national university hospital from May. 1 1987, to April. 30 1994, who sustained mandibular fractures. Factors considered were sex, age, date of injury, causes of injury, type of fractures, anatomic site of fractures, associated anomaly, duration from injury to operation, methods of treatment, and complications. The results were obtained as follows 1. The ratio of male/female was 6.4 : 1 2. The highest incidence was in the 21 to 30 years age group (40.5%). 3. The monthly distribution revealed that June is the month with the greatest percentage of mandibular fractures(14.3%), followed by September(11.9%), February (11.1%). 4. The each number of mandibular fractures was increased from year to year with the excep tion of 88.5-89.4 arid 91.5-92. 4. The peak incidence occured in 93.5-94.4(35.7%), especially. 5. Most common cause was the traffic accident(45.2%), followed by fall down (23.8%), assault (20.6%). 6. Type of fractures showed one mandibular fracture only 51.6%, two fractures 42.9%, three fractures 5.6%. 7. The most common site of fracture was mandibular symphysis(46.9%), followed by angle(22. 7%), condyle(22.2%), body(3.6%), ramus(2.6%), alveolus(2.1%). 8. Most common associated injury was facial laceration (41.3%), followed by other facial bone fracture(17.5%), and skull fracture(11.9%). 9. The main treatment type of mandibular fractures was intermaxillary fixation and internal fixation with miniplate(40.5%). And, cases applied rigid internal fixation without intermaxilly fixation was 32.5%. 10. Most common complication was postoperative wound infection (3.2%).
