An avulsion fracture of the anterolateral tibial epiphysis or Tillaux fracture is commonly seen in adolescents, reported first by Paul Jules Tillaux in 1892. Adolescent Tillaux fracture occurs during the period when the lateral physis is still open and the anterior-inferior tibiofibular ligament is stronger than the physis, so rarely occurs in adults. An avulsion fracture of the posterior inferior tibiofibular ligament, Volkmann fracture, occurs counterpart of Tillaux fracture. In this study, a tennis player injured during sliding and diagnosed as the rare simultaneous Tillaux-Chaput fracture and Volkmann fracture, is reported with the mechanism of injury, clinical importance of syndesmosis, sprain, and fracture of the ankle joint.

Purpose: To report a case of keratitis caused by Brevundimonas diminuta/vesicularis.Case summary: A 20-year-old man presented with decreased visual acuity and glare in his right eye from 2 days earlier. At the first visit, slit lamp examination revealed a 1.5 × 1.5 mm2-sized stromal infiltration, an edematous cornea and endothelial deposits in the center of the right eye. Microbiological examinations were performed from corneal scrapings. Treatment was started with topical eye drops (fortified cefazolin, fortified tobramycin) as empirical antibiotics. After several days, the cultures revealed Brevundimonas diminuta/vesicularis. After treatment with empirical antibiotic eye drops, the symptoms and visual acuity improved. Conclusions We report a case of infectious keratitis caused by Brevundimonas diminuta/vesicularis, which has never previously been reported in the Republic of Korea.

OBJECTIVE: The aim of this study was to evaluate the positive rate of squamous cell carcinoma antigen (SCC), carcinoembryonic antigen (CEA), and CA-125 according to clinical stage and histology. We also determine the rate of normalization of SCC after surgical and radiation therapy. RESULTS: In 222 patients with cervical cancer, the pre-treatment positive rate of SCC, CEA, and CA- 125 were 38.7%, 24.3%, and 19.8%, respectively. The positive rate of SCC by clinical stage were 12.9% for stage I, 60.5% for stage II, 88.2% for stage III, and 87.5% for stage IV. The positive rate of CEA by stage were 7.8% for stage I, 36.4% for stage II, 83.3% for stage III, and 75% for stage IV. The positive rate of CA-125 by stage were 5.9% for stage I, 23.3% for stage II, 83.3% for stage III, and 75% for stage IV. The positive rates of SCC, CEA, and CA-125 were significantly increased by clinical stage. According to histology, the positive rate of SCC (39.8%) was more significantly higher than the positive rates of other tumor makers in squamous cell carcinoma of the uterine cervix. The positive rate of CA-125 was higher than the positive rate of other tumor markers in adenocarcinoma and adenosquamous carcinoma of the uterine cervix, but it was not statistically significant difference. CONCLUSION: SCC have been shown to be higher positive rate than any other tumor markers in patients with cervical cancer. The positive rates of SCC, CEA, and CA-125 were significantly increased by clinical stage. Concomitant measurement of SCC, CEA, and CA-125 may be more useful than measurement of SCC alone, and further study was needed.

Acardiac fetus in triplet pregnancy is a very rare, fatal congenital anomaly that had not been reported in Korea. It only occurs in multiple gestations associated with placental vascular anastomoses between the affected fetus and its co-twin. The major complications associated with acardiac fetus in triplet pregnancy are congestive heart failure in normal pumping fetus, maternal polyhydramnios, preterm labor, intrauterine fetal death, etc, and perinatal diagnosis can be made with the perinatal ultrasonographic examination. We report a case of acardiac fetus in a spontaneous triplet pregnancy at 23 weeks of gestational age with a brief review of the literature.

PURPOSE: To compare the antibiotic release kinetics of the implant coated with antibiotic-impregnated polymers MATERIALS AND METHODS: Authors used polylactic acid (PLA) and polylactic-co-glycolic acid (PLGA) as the biodegradable carriers, gentamicin sulfate as the antibiotic and Steinmann pin as the implant. Ten Steinmann pins were coated with gentamicin of each 10, 20 and 30% mixture of PLA or PLGA for the elution kinetics study. In the elution study, total 60 coated implants were incubated in 10 mL of phosphate buffered saline (PBS) at 37 delta C and sampled at 6 hrs, 1, 3, 6, 9, 12, 15, 20, and 25 days. Assays were performed with fluorescence polarization immunoassay. Statistical analysis was done with SAS release 2.01. RESULTS: Released concentration of GM decreased with time. Minimum inhibitory concentration was maintained until 6th day on PLA 10% subgroup, 9th day in the 20 and 30% subgroups, until 6th day on PLGA 20% subgroup, and 3rd day in the 10 and 30% subgroups. Released concentrations were significantly higher in all PLA subgroups than in PLGA as a parameter of sampled time (all p<0.05). There was no statistical difference between PLA 20 and 30% subgroup after 12th sampled day (p=0.2636). CONCLUSION: PLA-GM group showed higher effective concentration for longer time than PLGA-GM group. 20 and 30% subgroups of PLA-GM showed prolonged maintenance of minimum inhibitory concentration compared with 10% subgroup, but there was no difference between the two groups.

BACKGROUND: Different types of injury to the sciatic nerve branches produces different levels of each kind of nociception. In this study, we undertook to identify the nature of the partial sciatic nerve injury that affects nociceptive reaction to subcutaneous formalin injection, and to determine the branch of the sciatic nerve involved. METHODS: Sprague-Dawley rats were randomly divided into 4 groups, control group (n = 9) in which a sham operation was performed, a sural nerve transection group (n = 5), a tibial nerve transection group (n = 5), and a common peroneal nerve transection group (n = 5). Under enflurane anesthesia, sural, tibial, or common peroneal nerves were injured and responses to formalin test were compared for the four groups 24 hours after surgery. RESULTS: Pain behavior in the tibial and common peroneal nerve transected groups reduced in phase 2, but not in phase 1, while sural nerve transected group showed no change in response in either phase. CONCLUSIONS: Tibial and common peroneal nerves mainly affect phase 2 reaction in the formalin test in this partial sciatic nerve injury model.

BACKGROUND AND OBJECTIVES: Pulmonary arterial stenosis is a relatively common complication after corrective operation of congenital heart disease. Unilateral stenosis of pulmonary arteries could result in decrease perfusion of affected lung, pulmonary regurgitation, or elevation of right ventricular pressure. Eventually there are increasing risks of right ventricular failure, arrhythmia, or sudden death. However we have limited data of pulmonary arterial stent in paediatric population as the treatment of branch pulmonary stenosis. This study aimed at validating the effectiveness and investigating complications of pulmonary arterial stent implantation in a single institution during mid-term follow up period. SUBJECTS AND METHODS: A total of 42 patients (50 stents) were implanted for treating branch pulmonary arterial stenosis. We used cardiac catheterization for comparing diameter after stent implantation directly and lung perfusion scan indirectly. We also investigated any adverse effect relating the procedure. RESULTS: Percent stenosis of stenotic lesions were decreased from 54.1+/-10.7% to 22.8+/-12.5% (p<0.001) and degree of decrement in affected lung perfusion was declined from 22.7+/-8.0% to 10.3+/-9.0% (p<0.001) immediately and lasts during mid-term follow up period. Complication rate relating the procedure was 12% (6 out of 12) and there was no mortality case. CONCLUSION: This series showed immediate and short term effectiveness of pulmonary arterial stent in congenital heart defects. We concluded that percutaneous transcatheter implantation of pulmonary arterial stent was safe and effective during short and mid-term follow up period.

PURPOSE: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumor of the gastrointestinal tract. Recent studies have revealed much of the biological and genetics underpinning GISTs. METHODS: KIT, PDGFRA, NF2 and GPHN mutations were examined by PCR-SSCP and DNA sequencing. Immunohistochemical analyses of CD117, CD34, SMA, S-100 and desmin were performed in 11 GISTs cases, and each tumor classified as being either very low, low, intermediate or high risk. RESULTS: Mutation in exon 11 of KIT was identified in 6 of the 11 GISTs, but mutations in exon 9, 13 and 17 of KIT were not detected. Three cases lacking KIT mutations showed PDGFRA mutations. No NF2 mutations were detected. GPHN gene mutation in exon 1 was identified in one case, which showed a simple point mutation in exon 11 of KIT. In a correlation between the mutation types and risk of aggressive behavior, four tumors involved multiple ( >2 codons) KIT mutations and one showed a point mutation of KIT plus a GPHN mutation were high risk, but one tumor with a point mutation of KIT showed a low risk. Three tumors having a PDGFRA mutation were of intermediate or very low risk. CONCLUSION: Mutations at exon 9, 13 or 17 of KIT and a NF2 mutation are considered rare in sporadic GIST. KIT and PDGFRA mutations appeared to be alternatives. A GPHN mutation occurring with a KIT mutation may be a secondary change in the pathogenesis of GIST, as the KIT mutation is a major event in GIST. KIT mutant GIST may have a poorer prognosis than PDGFRA mutant GIST.
