PURPOSE: The treatment of children mandibular condyle fracture that is severely displaced is controversial. The conservative treatment of it may lead to complications- mandibular deficiency, asymmetry, malocclusion and temporomandibular joint dysfunction. Moreover, open reduction carries risks for growth retardation, facial nerve injury, scarring and joint stiffness. The aim of this article is to present an alternative technique of the treatment by using a threaded Kirschner wire and external rubber traction. METHODS: From November 2005 to May 2008, three patients underwent the management by using a threaded Kirschner wire and external rubber traction. A threaded Kirschner wire was inserted in the condylar segment by using a C-arm. We applied the external rubber traction, and we reducted the segment progressively until complete reduction. The mandibular-maxillary fixations were removed after 3 weeks, and patients were sent to training for mouth opening. RESULTS: The technique didn't result in complications- joint dysfunction, facial nerve injury, sore, infection and nonunion during follow-up period. Radiologic follow-up examinations revealed correct reduction in all patients. In all cases, we found restoration of preinjury occlusion and temporomandibular joint function. CONCLUSION: Closed reduction of children mandibular condyle fracture by using a threaded Kirschner wire and external rubber traction did achieve anatomic reduction and restore mandibular height. This alternative technique is simple, effective, inexpensive, easy to apply and minimally invasive.

BACKGROUND: Intravenous fentanyl has been used for acute postoperative pain management, but has not always provided reliable adequate analgesia, including patient-controlled analgesia (PCA). The purpose of this study was to investigate the efficacy of time-scheduled decremental infusion of fentanyl for postoperative analgesia. METHODS: Ninety-nine patients, aged 20-65 years, undergoing laparoscopic-assisted hysterectomy using total intravenous anesthesia (TIVA) were randomly assigned into one of the three groups. Their background infusions of fentanyl diluent (2 ml/hr of diluent was equivalent with 0.5 microg/kg/hr of fentanyl) with PCA were maintained at the fixed-rate of 2 ml/hr until the postoperative 24 hr (FX2-2-2), or at the decremental rates of 6.0, 4.0, 2.0 ml/hr (D6-4-2) and 8.0, 4.0, 2.0 ml/hr (D8-4-2). The visual analogue score (VAS), incidence of inadequate analgesia, frequency of PCA intervention, and side effects were evaluated. RESULTS: VAS was significantly higher in FX2-2-2 than in D6-4-2 and D8-4-2 until postoperative 3 hr (P < 0.05). After postoperative 4 hr, VAS was significantly higher in FX2-2-2 than D8-4-2 (P < 0.05). The incidence of inadequate analgesia of FX2-2-2 was significantly greater than D6-4-2 (P = 0.038) and D8-4-2 (P < 0.001) until postoperative 1 hr. None of the patients had ventilatory depression, and postoperative nausea and vomiting were not significant among the groups. CONCLUSIONS: The time-scheduled decremental background infusion regimens of fentanyl, based on the pharmacokinetic model, could provide more effective postoperative pain management after TIVA, and the side effects and the risk for morbidity were not different from the fixed-rate infusion regimen.

PURPOSE: The standard treatment for aortic aneurysms is surgical replacement with a prosthetic graft. Currently there is great interest in endoluminal intervention for treatment of aortic aneurysm. The purpose of this study was to evaluate the safety and effectiveness of endoluminally placed Stent-graft for the treatment of aortic aneurysms. MATERIALS AND METHODS: Transluminal endovascular Stent-graft placements were attempted in 9 patients with infra-renal aortic aneurysms(n=6), thoracic aortic aneurysm(n=l), and aortic dissection(n=2). The endovascular Stent-grafts were custom-designed for each patient and were constructed of self-expandable modified Gianturco Stents covered with polytetrafluroethylene. The Stent-grafts were introduced through a 16-18 french sheath and expanded to 17-30mm in diameter. The endovascular therapy was performed using a common femoral artery cutdown with local anesthesia. RESULTS: The endovascular Stent-graft deployment was achieved in 7 of 9 patients. Two cases failed deployment of the Stent-graft due to lilac artery stenosis and tortousity. There were complete thrombosis of the thoracic and infra-renal aortic aneurysm surround the Stent-graft in 3 patients, and persistent leak with partial thrombosis in 2. Two patients with aortic dissection were successfully treated by obliteration of entry tears. There were no major complication associated with Stent-graft placement. CONCLUSION: These preliminary results show that transluminal endovascular Stent-grafts offer great promise and good results. Further investigation is needed to establish its long-term safety and efficacy.

Retrorectal tumors are particularly rare among the adult population, occurring in 1 of 40,000 hospital admissions. Clinical diagnosis is difficult and is often delayed because of vague symptoms. This study aimed to investigate the clinicopathological features of retrorectal tumors. Between January 1999 and March 2005, 10 patients were diagnosed with retrorectal tumors at the Department of Surgery, Yonsei University Medical Center, and their medical records were reviewed. We analyzed chief complaints, imaging studies, surgical approaches and pathologic examinations. Out of 10 patients, 8 were female and 2 were male. The mean age was 42.8 years. Four patients had no symptoms. Perianal and abdominal pain were the most common presentations. CT and MRI were the most frequently performed imaging studies. Surgery was performed in 9 patients. Postoperative pathologic diagnosis was possible in 9 patients. An epidermal cyst was the most common tumor (4 patients); others included a mature teratoma, an adenocarcinoma from a tail gut cyst, a duplication cyst, a neurogenic tumor, and a smooth muscle cell tumor. Imaging techniques like CT scans, MRI and TRUS are helpful to determine the size and the extent of a tumor and its relationship to the surrounding anatomical structures for the operative approach. A surgical resection is the standard of treatment and demonstrates good results and a good prognosis.

A fungal isolate collected from infected paprika (Capsicum annuum var. grossum) was characterized as Sclerotinia sclerotiorum based on its ability of sclerotium formation, physiological and molecular properties. When the isolate was grown on potato dextrose agar, oatmeal agar, and malt extract agar, it grew most well on PDA. Optimal temperature and pH for its growth were 25degrees C and pH 7, respectively. The fungal isolate produced sclerotia on PDA within 10 days, and the color and shape of the sclerotia were similar to those of S. sclerotiorum . The ITS rDNA regions including ITS1 and ITS2 and 5.8S sequences were amplified using ITS1F and ITS4 primers from the genomic DNAs of the paprika isolate and other known pathogenic S. sclerotiorum isolated from different crops in Korea, and their nucleotide sequences were determined. Sequence comparison analysis showed the ITS rDNA of the paprika isolate shares 100% sequence identity with those of S. sclerotiorum isolated from red pepper, lettuce and a S. sclerotiorum isolate registered in GenBank DNA database. Neighbor joining analysis based on the ITS rDNA sequence revealed the paprika isolate has very close phylogenetic relationships with known Sclerotinia sclerotiorum isolates. This is the first report that S. sclerotiorum has been found associated with paprika rot in paprika growing countries.

Ruptured dissecting aneurysm of the vertebral artery requires a rapid treatment because of the high rate of fatal early rebleeding. Stent-assisted coil embolization has been introduced as an effective procedure for both aneurysmal occlusion and parent artery preservation. We report a case of successful urgent treatment of ruptured dissecting aneurysm using a self-expandable, intracranial stent (Neuroform(R)) and a coated coil (HydroCoil(R)).

PURPOSE: To investigate the effect of lateral buttress on the fracture healing of Jensen type 4 intertrochanteric fracture of the femur treated by dynamic compression hip screw (DCS) in elderly patients, retrospectively. MATERIALS AND METHODS: From March 1999 to February 2003, 54 patients, older than 65 years, of Jensen type 4 intertrochanteric fractures of the femur treated by DCS were included. The relationship between the structual integrity of lateral buttress measured by proximal-medial fragment angle (PMFA) and postoperative neck-shaft angle, penetrating length of lag screw, the sliding length and incidence of fixation loss were evaluated. RESULTS: Among 38 patients of group II (PMFA above 50 degree), 6 cases (15.8%) including 4 cases of cutting out of lag screw from femoral head, 1 case of nonunion and 1 case of excessive extrusion of lag screw failed radiologically. But there was no fixation loss case in 16 cases of group I (PMFA 50 and below 50). The neck-shaft angle in last follow-up was 138.1 degree in group I and 132.1 in group II. The sliding length of lag screw was 7.0 mm in group I and 12. 5 mm in group II (p<0.05). CONCLUSION: Preoperative evaluation of intactness of lateral buttress measured by proximal-medial fragmentary angle is an useful method in treatment of Jensen type 4 intertrochanteric fractures treated by DCS in elderly patients.

PURPOSE: The purpose of this study was to evaluate the clinical and abdominal ultrasonogra- phic (US) features of spontaneously reduced transient small bowel intussusception in chlidren. METHODS: We retrospectively reviewed the clinical and US findings of 98 children with intussusception who were admitted to the Pediatric Department of Ulsan Dong-Kang General Hospital from Mar. 1999 to Feb. 2000. RESULTS: 1) Among 98 cases, there were 12 cases (12.3%) of transient small bowel intussusception (TSBI) and 86 cases (87.7%) of classic intussusception (CI). 2) The peak incidence of age in TSBI was over 3 years, which was older than that in CI. With regard to sex distribution, male predominated in both type. 3) Clinical symptoms and signs including cyclic irritability, vomiting, bloody stool, and abdominal mass in TSBI group were less common than those in CI group (41.7%, 33.4%, 0.0%, 0.0% vs 91.9%, 59.3%, 41.9%, 26.7%, respectively) but persistent abdominal pain was more common in TSBI group than in CI group (58.5% vs 11.2% ). 4) The size of total target sign and surrounding peripheral hypoechoic rim of TSBI group on US were smaller than those of CI group (11.9±2.61 mm, 2.08±1.15 mm vs 26.91±5.98 mm, 7.86±2.77 mm, respectively). 5) Concomittant illness was found more frequently in TSBI group than in CI group (66.7% vs 26.7%). 6) All case of TSBI group were reduced spontaneouly, which were confirmed by US, but none of CI group. CONCLUSION: Transient small bowel intussusception is probably more common than generally thought and its clinical and US findings is quite different from classical obstructing intussus-ception. Because all of our cases resulted in spontaneous reduction, we recommend careful observation and repeat examination rather than an immediate operation in transient small bowel intussusception.
