It is often difficult to achieve bony union and eradicate infection in treating infected non-unions of the fractured long bones. Authors carried out a clinical analysis of the 35 infected non-union cases, all aged 21 years or older, treated and followed for 6 months to 6 years from July 1979 to July 1988 in order to determine the possible factors which might influence the time required for attaining union. The results were as follows: l. In 22 of the 35 infected non-unions, the primary fracture site was open (62.9%). The remaining 13 cases (37.1% ) were the closed fractures associated with postoperative infection. 2. The sites of infected non-union were tibia in 19 (54.3%), femur in 13 (37.1%), and upper extremity in 3 (8.6%) cases. Tibia was more often involved in open fractures (63.6%). Femur, on the other hand, was more involved in closed fractures (61.5%). 3. After an average of 3.3 times of bony procedures, primary fixation was left in place in 15 (42.9%), external fixation was required in 11 (31.4%), and internal fixation was performed in 9 (25.7%). Bone graft was performed in 26 cases (74.3%). 4. Time required for achieving union was 7.1 month with stable primary fixation and 21.7 months with unstable primary fixation. Femur and tibia united at 10.5 (mean; ranged from 4 to 29) and 7.0 (mean; ranged from 3 to 19) months, respectively. 5. Bony union was delayed as the number of prior surgical procedures before successful treatment increased; the time for union was significantly shorter when either stable primary fixation or external fixation was combined with bone grafting. 6. Firmer bony union was achieved after performing Osteoperiosteal decortication with autogenous cancellous bone graft even in the presence of remaining infection at the non-union site.

The tricuspid valve is not a simple but a complex structure, tricuspid valve complex. This complex is composed of tricuspid orifice, annulus, valve leaflet, chordae tendineae and papillary muscles. There are flew articles about these structures. The authors studied tricuspid valve complex in 53 cases of normal korean adults, such as circumference of tricuspid annulus, the maximum diameter of the tricuspid orifice, height and breadth of the cusps, including commissures, the ratio of rough to clear zone, the number of scallops of posterior cusp, the number, length and pattern of arrangement of the several types of chordae, the number and morphological characteristics of papillary muscles.

OBJECTIVE: Hysterectomy is one of the most common gynecological operations. The objective of this study is to compare the efficacy of suturing methods of vaginal cuff between laparoscopic and vaginal approach. METHODS: One hundred and sixty one cases of laparoscopic hysterectomy were devided into two groups. In group A(n=67), vaginal cuff was sutured by laparoscopic suture technique and in group B(n=94), vaginal cuff was repaired by vaginal approach. RESULTS: There were no significant differences in uterine weight, hospital stay, pre-and postoperative hemoglobin level and complications including febrile morbidity in two groups. Operation time was significantly shorter in group B(p=0.05). CONCLUSION: Transvaginal repair of vaginal cuff showed shorter duration of operation time than laparoscopic suture technique in total laparoscopichy sterectomy.

Relining and rebasing are essential for long-term success and oral health in removable prosthodontics. Major features of failures between metal base and relining resins are adhesive failure due to lack of chemical bonding. The purpose of this study was to find a better metal primer and metal surface treatment method that enhance the bonding strength with relining resin materials. The surfaces of ticonium alloys were treated with 25micrometer sandblasting (Group A), stone wheel (Group B), stone wheel and EZ oxisor (Group C), 75micrometer sandblasting (Group D) and EZ oxisor application after 75micrometer sandblasting (Group E). They were subdivided into no primer application (Group I), MR bond application (Group II) and Metafast bonding liner (Group III). Then specimens were completed though being bonded with relining resins. The specimens were stored in 38degrees C water for 48 hours and tensile strength was measured using the universal testing machine. The results were as follows, 1. Primer application groups showed higher bond strength than no primer application group(p<0.05). 2. In comparison with primer application groups, MR bond group showed higher bond strength than Meta fast bonding liner application group(p<0.05). 3. In comparison with surface treatment methods. Bond strengths of group A and B were significantly different with group C, D, and E, and group C were significantly different with group D, and E in no primer application group(p<0.05). In primer application groups, group A, B, C were significantly different with group D and E(p<0.05). According to results of this study, Metal primer application and metal surface roughening were considered to be advantageous for relining of metal base dentures.

Hereditary nonpolyposis colorectal cancer(HNPCC) is an autosomal dominantly inherited disease associated with a marked increase in cancer susceptibility, especially cancer of the colorectum. The frequency of HNPCC in the general population is yet to be determined, but HNPCC may account for as much as 2% to 5% of colorectal cancer, Colorectal cancer in HNPCC differs from sporadic colorectal cancer by an early age of cancer onset, proximal predominance of colorectal cancer, an excess of synchronous and metachronous colorectal cancer, and excess extra-colonic cancers. We have found 5 HNPCC families since 1992 when we reported first HNPCC family (KHU-Hl) In order to register the patients of HNPCC and to review the clinicopathologic feature and appropriate management, we have analysed 5 HNPCC families. Five HNPCC families included 16 colorectal cancer patients(14 males and 2 females). The average age of first diagnosis was 39. Among 16 patients, 8 patient were operated at the KyungHee University hospital and their operative and pathologic records were available. Two synchronous and seven metachronous cancers were founded, so that eight patients had 15 colorectal cancer lesions. Ten cancers were located proximal to splenic flexure and five were distal. Partial resection of colon was performed in seven cases except one when the first diagnosis was made and recurrence was founded in 5 patients. Recurrence was treated by total colectomy in 3 cases and subtotal colectomy in two. In conclusion, we re-confirmed that HNPCC patient should be treated by no less than a subtotal colectomy because of high multiplicity and high recurrence rate of partial resection.
