The aim of present study was to evaluate the influence of periodontal status of adjacent tooth and loading time to the prevalence of red complex of implant sulcus. In 97 patients, partially edentulous subjects with endosseous root-form implants were selected. All subjects were medically healthy and had not taken systemic antibiotics and professional plaque control 3 months before sampling. The number was as follows: clinically healthy implants:161, clinically unhealthy implants:22, clinically healthy adjacent teeth:73, clinically unhealthy adjacent teeth:38. All teeth and implants of each patient were examined probing depth(PD), modified sulcus bleeding index(mSBI), and modified plaque index(mPI), and samples of subgingival plaque were obtained at each site with sterile curet or fine paper points, then the plaque transferred to PBS. Obtained samples were examined for the presence of P. gingivalis, T. forsythensis, and T. denticola by the polymerase chain reaction (PCR). The relationship among clinical parameters and the colonizations by the 3 bacterial species from adjacent teeth and implants region were analyzed by student t-test (p<0.05). The results of this study were as follows: 1. mPI and mSBI of implant increased with increasing of same indices of adjacent tooth(p=0.03,0.001), but not in the PD . 2. The mPI, mBI, PD of implants was higher when red complex exist. 3. The prevalence of red complex was higher when the periodontal condition is unhealthy. 4. The prevalence of red complex of implants has no significant relation to the probing depth of adjacent tooth. 5. Prevalence of P. gingivalis, T. forsythensis of implants increased with loading time. (p=0.02,0.018) These results shows the importance of oral hygiene and supportive periodontal therapy.

BACKGROUND/AIMS: To review the cases of surgically-treated intrahepatic cholangiocarcinoma, and to evaluate the clinical and pathologic features of intrahepatic cholangiocarcinoma that may affect longterm survival among Korean patients. MATERIALS AND METHODS: From 1990 to 1997, 28 patients with intrahepatic cholangiocarcinoma underwent laparotomy. Among them, resection was performed in 25 patients and wedge resection in only 3 patients. The liver resections included: 5 right lobectomies, 1 right trisegmentectomy, 7 left lobectomies, 3 extended left lobectomies, 2 hepatopancreatoduodenectomies and 7 segmentectomies. Curative resection was performed on 15 patients. The histological sections of all resected specimens were immunohistochemically stained with p53 and Ki-67 monoclonal antibodies to assess biological behavior of the tumor cells. The cumulative survival rate and clinicopathological factors, including biological markers (p53, Ki-67), that may influence prognosis were analyzed stastistically. RESULTS: The patients undergoing curative resection survived significantly longer than the patients undergoing noncurative resection. The median survival time for patients with curative resection was 24 months (mean, 34+/-8 months) with 1-, 2-, and 3-year survival rates of 66.6%, 44.4%, and 35.6%, respectively. The median survival time for patients with noncurative resection was 3 months (mean, 8+/-3 months) with 1- and 2-year survival rates of 26.7% and 13.4%, respectively. Univariate analysis showed that positive regional lymph node significantly correlated with poor prognosis (p=0.004); and that curative resection significantly correlated with better prognosis (p=0.001). Age, sex, tumor size, the degree of cell differentiation, gross type of tumor, and p53 and Ki-67 labeling index had no significant correlation with prognosis. CONCLUSION: Our results support the idea that an aggressive liver resection along with regional lymph node dissection is recommended for long-term survival. The validity of the molecular biologic tumor markers (p53, Ki -67) as a prognostic factor is not yet clearly defined.

Odontogenic keratocysts are benign intraosseous tumors of odontogenic origin that occur most commonly in the jaw. In particular, they have a predilection for the angle and ascending ramus of the mandible. In contrast, odontogenic keratocysts arising in the maxillary sinus are relatively rare. Two such cases are reported herein. In addition, the English literature that concerns odontogenic keratocysts of the maxillary sinus is reviewed.

BACKGROUND: Bipolar hemiarthroplasty for unstable intertrochanteric fractures in elderly patients is a viable option that can prevent the complications of an open reduction, such as nonunion and metal failure. This study evaluated the clinicoradiological results of cementless bipolar hemiarthroplasty for unstable intertrochanteric fractures in elderly patients. METHODS: Forty hips were followed for more than 2 years after cementless bipolar hemiarthroplasty using a Porocoat(R) AML Hip System. The mean age was 78.8 years and the mean follow-up period was 40.5 months. The Harris hip score and postoperative hip pain were analyzed clinically. The radiological results were assessed using a range of indices. RESULTS: At the last follow-up, the mean Harris hip score was 80.6 points. There were one case of hip pain and one case of thigh pain. Twenty-four cases (60%) showed no decrease in ambulation capacity postoperatively. Radiologically, there were 23 cases (57.5%) of fixation by bone ingrowth and 17 cases (42.5%) of stable fibrous fixation. There were no cases of osteolysis. Eleven cases (27.5%) of new bone formation were found around the stem. All stems were stable without significant changes in alignment or progressive subsidence. CONCLUSIONS: The short-term results of cementless bipolar hemiarthroplasty in elderly patients with unstable intertrochanteric fractures were satisfactory.

BACKGROUND AND PURPOSE: Cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most-common single gene disorder of cerebral small vessel disease. There is no definite evidence of genotype-phenotype correlation in CADASIL. However, recent studies have shown the unique phenotypic feature of NOTCH3 R544C mutation. METHODS: We investigated the phenotypic spectrum of NOTCH3 R544C mutation in 73 CADASIL patients in Jeju between April 2012 and January 2014. RESULTS: Of the 73 subjects from 60 unrelated families included in this study, 40 (55%) were men. The mean age of the subjects was 62.2±12.2 (range 34-86 years). Cerebral infarction was the most frequent manifestation (37%), followed by cognitive impairment (32%), headache (17%), psychiatric symptom (16%), intracerebral hemorrhage (12%), transient ischemic attack (7%), and seizure (1%). The mean age of the subjects with ischemic or hemorrhagic episodes was 64.9±10.9 (range 41-86 years). A diagnosis of dementia was made in 12 subjects (16%). The mean age of the subjects with dementia was 75.6±6.5 (range 62-86 years). About 3% of subjects were unable to walk without assistance at assessment. Only one subject had developed chronic headache before the 40s. CONCLUSIONS: Our data support the hypothesis that CADASIL patients with R544C mutation in Jeju have relatively late onset disease.

A low iodine diet (LID) is the recommended preparation for radioactive iodine treatment. However, the recommended duration and stringency of LID are different among each recommendation. More stringent LID is expected in Korea because Korea is a iodine-rich region. We investigated the decrement of urine iodine excretion by two-week stringent LID for remnant thyroid ablation with radioactive iodine in Korean patients with thyroid cancer, prospectively. MATERIAL AND METHOD: From November 2006, patients who referred to our hospital for remnant ablation after total thyroidectomy were included in this study. To decrease total body iodine, our protocol included three strategies. First, we checked medication which could inhibit the radioactive iodine uptake. Second, the date of I-131 treatment was scheduled at least 3 months later if contrast agent had been used. The last strategy was two-week stringent LID education by specialized nutritionist. Before and after two-week stringent LID, 24hr-urine iodine was analyzed respectively. 24hr-urine creatinine was also analyzed for determining more valid 24hr urine sampling subgroup. RESULTS: Total 51 patients were finally enrolled. Average of 24hr-urine iodine excretion was significantly lowered (787+/-2242 -> 85+/-85 microgram/d, p=0.03) after LID and 74.4% of patients reached below the recommended urine iodine excretion level (<100 microgram/d). In subgroup (n=14), similar results was showed (505+/-666 -> 99+/-116 microgram/d, p=0.05) and 78.6% of patients met the criteria. CONCLUSION: Most patients could reach below the recommended urine iodine level after two-week stringent LID. Therefore, in our opinion, at least two-week stringent LID should be recommended in Korea.

PURPOSE: To determine the clinical efficacy of percutaneous vertebroplasty in cases of painful and medically intractable osteoporotic vertebral compression fracture. MATERIALS AND METHODS: Ninety-eight patients (20 men and 78 women; mean age, 69 years) underwent 122 per-cutaneous vertebroplasty procedures for the treatment of osteoporotic vertical compression fracture. For the evaluation of bone mass, bone densitometry was performed in 45 patients, and to assess the recent evolution of the fracture, all 98 underwent MRI. Percutaneous vertebroplasty involves percutaneous transpedicular puncture of the involved vertebrae followed by the injection of a Polymethylmethacrylate(PMMA)-Barium mixture into the vertebral body. To assess leakage of the mixture into the epidural tissue, neural foramina, venous plexus and paravertebral tissue, we then immediately obtained a computerized tomographic (CT) scan, assessing the clinical efficacy of the procedure on the basis of time required for pain relief (defined as more than 60% reduction of initial pain), and time required for ambulation without significant pain. RESULTS: Percutaneous vertebroplasty was successful in all patients. Pain relief was accomplished within 1-5(mean, 1.8) days and early ambulation without significant pain was possible within 2 -15 (mean, 3.3) days. Post-procedural CT scanning revealed leakage of the PMMA-barium mixture into Paravertebral tissue(n=41), the paravertebral venous plexus (n=34) and epidural tissue (n=4). No neural foraminal leakage was identified, and no procedure-related complication requiring surgical treatment occurred. CONCLUSION: Percutaneous vertebroplasty is an effective new interventional procedure for the treatment of osteoporotic vertebral compression fracture. It relieves pain, provides early mobilization, and strengthens involved vertebral bodies.

PURPOSE: To assess the comparative growth of the four long bones of the lower extremities after the tibial shaft fractures in children. MATERIALS AND METHODS: Thirty-eight children (age, 8.2+/-2.6) with tibial shaft fractures treated with a closed reduction and a long leg cast were enrolled in this study. The mean follow-up was 54.4 months (range, 24-96). The medical records and Bell-Thompson images were retrospectively reviewed. RESULTS: The clinical results were excellent in all cases. The fractured tibia showed overgrowth (4.4+/-3.3 mm) compared with the contralateral side. The ipsilateral femur showed mild over-growth (0.9 mm+/-3.7), and the final leg length discrepancy was 5.3 mm+/-5.4. Four ipsilateral femurs showed overgrowth >10 mm. Gender, the level of the fractures and associated fibular fractures did not affect the overgrowth of the fractured tibia (p>0.05). However, age might affect the amount of overgrowth (p=0.005). CONCLUSION: Tibial shaft fractures in children treated with a long leg cast showed variable overgrowth. The final leg length discrepancy was influenced by the overgrowth of the ipsilateral femur as well as by overgrowth of the tibia.
