PURPOSE: The purpose of this study was to evaluate computed tomographic (CT) findings of deep neck space infection(DNSI) with particular attention to the differences in the spaces involved and in complications between odontogenic and nonodontogenic groups. MATERIALS AND METHODS: Forty-four patients(21 odontogenic and 23 nonodontogenic) were included in this study. Among odontogenic DNSls, 15 had the dental infection in the second or third mandibular molar. We compared the CT features between odontogenic and nonodontogenic DNSIs with special emphasis on the differences in the spaces involved and in the rate and type of complications. RESULTS: In all patients, CT clearly differentiated abscess from cellulitis. The most common spaces involved in 21 patients with odontogenic DNSl were the parapharyngeal(n=18), the submandibular(n=18), the anterior visceral(n=13), the masticator(n=9), and the sublingual(n=7) spaces. In contrast, in 23 patients with nonodontogenic DNSI, the anterior visceral space(n=14) was most frequently involved. The parapharyngeal, the submandibular, and the masticator spaces were statistically more frequently involved in odontogenic than in nonodontogenic DNSI(p<.05). Twenty-two patients had one or more complications shown by CT, of which airway compromise was more frequent and severe in odontogenicthan in nonodontogenic DNSI. CONCLUSION: We conclude that the parapharyngeal, the submandibular, and the masticator spaces are more significantly vulnerable in odontogenic DNSl than in nonodontogenic DNSl. The predilection for certain spaces of the neck in odontogenic DNSl seems to originate from the intimate relationship of the mandibular molars to the adjacent deep neck spaces.

BACKGROUND: Hand-foot-mouth disease (HFMD) is mainly caused by the infection of coxsackievirus A16. But recently several epidemics of HFMD with meningitis or myocarditis due to enterovirus 71 have been reported in Southeast Asia. It was necessary that the possibility of enterovirus 71 epidemic in Korea should be ruled out. This study was designed for the determination of causative agents of HFMD in Cheju province in the spring of 1998. METHODS: Serum specimens were collected from 45 pediatric patients with HFMD at Cheju Hankook Hospital in March and April,1998. Virus isolation was performed with RD cell culture through up to three passages. Reverse transcription-PCR and nucleotide sequencing were performed by the method of Oberste et al.(J Clin Microbiol 1999;37:1288-93). The serotypes of viral isolates were determined by BLAST program of National Center for Biotechnology Information, U.S.A. RESULTS: Virus could be isolates from 4 patients, whose age was ranged from 11 months to 3 years. All of 4 viral isolates showed about 430-bp product of RT-PCR using primers 011 and 012. The serotype showing the highest similarity with the nucleotide sequences of all of these viral isolates was coxsackievirus A16. CONCLUSIONS: The causative enteroviral agent of HFMD in Cheju province in the spring of 1998 was coxsackievirus A16. We could not detect enterovirus 71 from the patients' sera in Cheju Province in the spring of 1998.

The expression of the nuclear phosphoprotein p53, a product of tumor suppressor gene, has been noted in a number of human tumors as a tumor suppressor. nm23 is a gene associated with low tumor metastatic potential and has been proposed to be a metastasis suppressor gene. To assess the role of p53 and nm23 expression in colorectal tumorigenesis and the association with clinicopathological parameters, an immunohistochemical study for mutant p53 and nm23 was done using mouse monoclonal antibodies in 43 colorectal carcinomas, 55 tubular adenomas and corresponding normal mucosa. In the tubular adenomas, p53 expression was significantly correlated with the degree of atypism(p<0.05) but not with other variables as well as with nm23. In the colorectal carcinoma, there were evidence of some correlation between metastasis, laterality and p53; laterality, depth of invasion and nm23 expression, but without statistical significance. Other clinicopathologic features were not significantly correlated. In the aspect of 'adenoma-carcinoma sequence', normal mucosa was totally negative for both p53 and nm23, and they were increasingly expressed through tubular adenoma to carcinoma with statistical significance(p<0.05). Therefore, it is suggested that both p53 and nm23 expressions occur in and around the time of transition to carcinoma from adenoma but are not significantly associated with the infiltrative behavior and metastasis.

graft as a successful procedure that provides functional stabiIity. Complications reported include arthro5brosis, patellofemoral joint pain, patellar tendinitis, patellar tendon rupture, recurrent laxity, posterolateral instabi5ty, medial subluxation of the patella, chronic knee pain and painful neuroma. Among them, anterior knee pain was the rnost frequent eomplication. Authors performed arthroscopy assisted one tunnel technique for reconsction of the ACL using autogenous Bone Patellar tendon-Rone (BPTB) in 87 patients. Patients were divid@d into two groups based on the harvested side (knee) of the BPTB. Group 1 consisted of 45 cases of ipsilateral side and group 2 consisted of 42 cases of contralsteral side in harvesting the BPTB. The patients were foll4wed up for at least 12 months to determine whether using the BPTB harvested from the contralateral knee wguld reduce the anterior knee pain at the ACL reconstructed knee. Althaugh there were no statistically signifiqant differences between group 1 and 2 with regard to anterior knee pain, the prevalence of the anterior knee pain was less frequent in group 2 than group 1. This study showed that using the contralateral side harvested autogenous patellar tendon would be a possible protector for anterior knee pain and assists for early rehabilitation.

There is a controversy in patella retention or resurfacing in total knee arthroplasty (TKA) till today. Authors studied 52 cases of 45 patients recieved total knee arthroplasty with patella retention (Group 1, twenty-five cases) or patella resurfacing (Group 2, twenty-seven cases) in patients with osteoarthritis. All operations were done by senior surgeon and the implants used were LCS type (33 cases), AMK type (12 cases), Genesis type (5 cases) and Tricon M type (2 cases). The indications of patella retention were small patella, nearly normal articular cartilage, minimal pre-operative patellofemoral pain, poor patellar bone quality and young patients. Patella retention were performed only with LCS prosthesis, which patella groove of the femoral component is deep and anatomical. The operative approaches used were medial parapatella approach in neutral or varus knee and lateral parapatella approch for severe valgus knee and tilting or lateral subluxation of the patella. The mean follow-up period was 24 months (range 12 months to 5 years). The method for clinical evaluation was Hospital for Special Surgery (HSS) knee scoring (consisted of pain, function, range of motion). The method for radiographical evaluation was Knee societys radiologic evaluation system for tibial and femoral alignment, and Keblishs method for patello-femoral congruence. The clinical HSS knee score was average 90.9 points in both groups, and 91.9 points in group 1, 90.0 points in group 2, and there was no statistically difference in HSS knee score between the two groups (P<0.05). The radiologic results had no significant difference in alignment and patello-femoral congruence between the two groups (P<0.05). But the complications were one case of patella fracture, one patella tendon rupture, one anterior instability and two cases of infection in group 2. In conclusion, the results of both groups were satisfactory. We think that it have relation to strict selection of the patients for patella retension and the use of prosthesis that the patella groove of femoral component is deep and anatomical.
