Rieger's syndrome is a rare autosomal dominant developmental anomaly characterized by ocular and systemic abnomalities. These disorders are typically bilateral and usually diagnosed at birth or in the childhood. The most common ocular defects are hypoplasia of the iris, a prominent Schwalbe's line with iris strands and corectopia. A large number of patients have glaucoma due to devel-opmental defects of the anterior chamber angle structure. The authors experienced a case of Rieger's syndrome which was found in 31-year-old female, who had characteristic ocular and other systemic abnormalities. Associated glaucoma was well controlled by filtering surgery.

The Morel-Lavallée lesion (MLL) is a closed soft-tissue degloving injury, resulting in characteristic hemo-lymphatic fluid collection between the fascia and subcutaneous layers. The MLL was managed routinely with drainage and compression bandages, but sclerotherapy can be used in patients with chronic lesions refractory to first-line therapy. This paper presents a case of extensive recurrent chronic MLL treated with sclerotherapy using Abnobaviscum, which has been used to treat adhesion in malignant pleural effusion.

Fractures of the tibia are frequently encountered in mordern civilized society. Especially, those in distal 1/3 of the tibia have so many problems, such as angular deformity, osteomyelitis and nonunion because of anatomically scanty soft tissue. Many modalities of the treatment of fracture of distal 1/3 of the tibia were introduced. Among them, interlocking IM nailings were considered as one of the best modality. But, in interlocking IM nail, reaming of the medullary canal which destroys the endosteal circulation and causes thermal necrosis of the inner aspect of the cortical bone results in delayed union. And also, procedure for distal screw fixation is difficult and time-consuming. As for using flexible IM nails for fractures of distal 1/3 of the tibia, it was considered as not so satisfactory method due to lack of stability of fixation. However, the stability of fixation can be strengthened with fanning of the nails in distal fragment, using more than 3 nails and delay the protected weight bearing. Authors studied 25 cases of fractures of distal 1/3 of the tibia treated with closed flexible IM nailing at Sung Ae General Hospital, from July., 1987 to July., 1989, and obtained following results: 1. Among 25 cases, 4th decades were most common and males were more commonly involved. 2. Traffic accidents were the most common causes of injury and majority of 16 open fractures and 19 comminuted fractures, were caused by high energy mechanism. Among open fractures, type II were most common. 3. Two angular deformities less than 10 degrees, one proximal migration and one checkrein deformity were observed as complications, but, no clinically significant complications were noted. 4. The time for radiological union were 14.5 weeks in group without fibular fracture and 15.1 weeks in group with fibular fracture, and 14.0 weeks in closed fracture group and 17.2 weeks in open fracture group, and average in 15.6 weeks.

PURPOSE: To determine whether the compression technique is a valuable additional method for differentiating between benign and malignant breast masses. MATERIALS AND METHODS: The ultrasonographic findings of 95 benign and 53 malignant masses, all pathologically proven, were prospectively analyzed with regard to five diagnostic criteria: shape (regular/irregular), retrotumoral acoustic phenomena (posterior enhancement/posterior attenuation), internal echo pattern (homogeneous/inhomogeneous), compression effect on shape (distortion/no change), and compression effect on internal echo pattern (more homogeneous/no change). RESULTS: The number of cases of benign and malignant masses, respectively, was as follows: regular / irregular shape: 84/11, 9/44; posterior acoustic enhancement/posterior attenuation: 82/13, 16/37; homogeneous/inhomogeneous internal echo pattern: 78/17, 14/39; distortion/no change in shpae: 76/19, 5/48; and more homogeneous/ no change in internal echo pattern: 71/24, 3/50. For all diagnostic criteria for the differentiation of benign and malignant masses, the differences were statistically significant (p<.05). CONCLUSION: Ultrasonography is helpful for differentiating between benign and malignant breast masses. The compression technique is a valuable additional diagnostic method.

The effect of hemodialysis on intraocular pressure(IOP) was studied in 20 non-glaucomatous patients(40 eyes) with chronic renal failure. The IOP, body weight and systolic blood pressure were measured at pre- and post-hemodialysis and at every hour during 4 hours' hemodialysis period. IOP(Right: 13.4 +/- 2.2mmHg, Left: 13.9 +/- 2.3mmHg) was measured before hemodialysis. Following hemodialysis, blood pressure and body weight decreased significantly(P<0.05) and IOP increased significantly(Right: 14.2 +/- 2.5mmHg, Left: 14.8 +/- 2.6mmHg, P<0.05). However, there Was not statistical significance between increased IOP and the decreased body weight(Right r=0.05, Left r=-0.03) and systolic blood pressure(Right r=-0.05, Left r=0.23). This study shows that chronic renal failure patients may have a possibility for increased IOP after long period hemodialysis.

The ultimate goal of periodontal therapy is directed to arresting the progression of the disease, and regenerating the fibrous attachment. In order to achieve such treatment aim, the plaque and calculus must be eliminated and the physiological conditions of the root surface must be changed to facilitate the attachment and migration of the new fibroblasts, The method of changing the proper root surface conditions to promote the healing of periodontal tissue involves mechanical procedures, such as scaling and root planing, and chemical procedures such as tetracycline-HCl. However, the formation of a long junctional epithelium was most frequently observed type of healing. Thus, the aim of this study was to examine in vitro the influence of surface conditioning of dentin by TC-HCl on human gingival epithelial cell attachment. Human gingival epithelial cells were obtained from healthy retromolar pad area(under the age 23 years). Seventy two teeth extracted from severe periodontitis were used as study material. To evaluate the epithelial cell attachment to dentin, the prepared specimen was divided to four groups. For the control group, only scaling and root planing were carried out, and for the test group, 1 to 3, the concentration of the TC-HCl was 50, 125 and 250mg/ml, respectively. After cell cultivation time of 1-, 3-. 24 hour, for the indirect quantitative assessment of gingival epithelial cell attached to dentin sample, the absorbance of epithelial cell unattached to dentin was measured. The results were as follows; 1. There was no statistically significant difference between scaling and root planing group and TC-HCl 50mg/ ml, 125mg/ml and 250mg/ml group about absorbance of unattached epithelial cell to dentin sample(p>0.5). 2. As time passes, the absorbance of unattached gingival epithelial cell to dentin sample was decreased statistically significant(p<0.05). 3. There was no statistically significant difference among the TC-HCl group(p>0.05) We concluded that there was similar effect on gingival epithelial cell attachment between TC-HCl conditioning on root surface and only scaling and root planing treatment

Presented in this paper are the experimental results that measure rapid prototyping (RP) errors in 3D medical models. We identified various factors that can cause dimensional errors when producing RP models, specifically in maxillofacial areas. For the experiment, we used a human dry skull. A number of linear measurements based on landmarks were first obtained on the skull. This was followed by CT scanning, 3D model reconstruction, and RP model fabrication. The landmarks were measured again on both the reconstructed models and the physical RP models, and these were compared with those on dry skull. We focused on major sources of errors, such as CT scanning, conversion from CT data to STL models, and RP model fabrication. The results show that the overall error from skull to RP is 0.64+/-0.36mm(0.71+/-0.66%) in absolute value. This indicates that the RP technology can be acceptable in the real clinical applications. A clinical case that has applied RP models successfully for treatment planning and surgical rehearsal is presented. Although the use of RP models is rare in the medical area yet, we believe RP is promising in that it has a great potential in developing new tools which can aid diagnosis, treatment planning, surgical rehearsal, education, and so on.
