Intracranial fibro-osseous lesion, also reported as calcifying pseudoneoplasm of the neural axis, is an uncommon lesion of the central nervous system. Since the discovery of this entity by Rhodes and Davis in 1978, there have been a total of 21 cases reported in the literature. We encountered one such case in a 28 year old male, who presented with left hemiparesis for 1 year. By the MR images, a 1.5 cm sized round mass was found at right parietal lobe near motor cortex. The mass lesion enhanced well, homogenously and revealed clear, slightly irregular margin. Excisional biopsy of the mass was performed. Microscopically the lesion was composed of calcified fibrous tissue with an amorphous gray-blue, coarsely fibrillar to chondromyxoid nodular areas. Sparse spindle cells, immunohistochemically negative for GFAP, vimentin and S-100, were scattered within the amorphous material. Palisading spindle or polygonal cells were present at the more cellular periphery of the lesion, which were vimentin positive but S-100 negative. There was no evidence of the pilocytic astrocytes, Rosenthal fibers, or GFAP positive hypertrophic astrocytes. Intracranial fibro-osseous lesions are apparently slow-growing with generally excellent prognosis after wide excision. The etiology remains unclear, but most investigators favor a reactive rather than neoplastic process.

This study was performed to describe the longitudinal management of recurrent temporomandibular joint (TMJ) ankylosis from infancy to adulthood in perspective of surgical and orthodontic treatment. A 2-year-old girl was referred with chief complaints of restricted mouth opening and micrognathia due to bilateral TMJ ankylosis. For stage I treatment during early childhood (6 years old), high condylectomy and interpositional arthroplasty were performed. However, TMJ ankylosis recurred and symptoms of obstructive sleep apnea (OSA) developed. For stage II treatment during early adolescence (12 years old), gap arthroplasty, coronoidectomy, bilateral mandibular distraction osteogenesis, and orthodontic treatment with extraction of the four first premolars were performed. However, TMJ ankylosis recurred. Because the OSA symptoms reappeared, she began to use a continuous positive airway pressure device. For stage III treatment after completion of growth (20 years old), low condylectomy, coronoidectomy, reconstruction of the bilateral TMJs with artificial prostheses along with counterclockwise rotational advancement of the mandible, genioglossus advancement, and orthodontic treatment were performed. After stage III treatment, the amount of mouth opening exhibited a significant increase. Mandibular advancement and ramus lengthening resulted in significant improvement in the facial profile, Class I relationships, and normal overbite/overjet. The OSA symptoms were also relieved. These outcomes were stable at the one-year follow-up visit. Since the treatment modalities for TMJ ankylosis differ according to the duration of ankylosis, patient age, and degree of deformity, the treatment flowchart suggested in this report could be used as an effective guideline for determining the appropriate timing and methods for the treatment of TMJ ankylosis.

Behcet's disease is a recurrent and multisystemic disorder which usually persists over many years and is classified under vasculitic syndrome. A classic triad in this disorder is composed of a recurrent oral ulcer, genital ulceration and uveitis. While intestinal Behcet's disease most commonly affects the ileoecal region, dysphagia associated with esophageal ulceration is very uncommon. A 34-year-old-female patient visited our hospital because of dysphagia, epigastric pain and fever. The patient had ulcers on the oral mucosa, soft palate and extemal genitalia. Multiple irregularly marginated ulcers surrounded with hyperemic edematous mucosa were found on the middle and distal esophagus and lesser curvature of the stomach by an esophagogastroduodenoscopic examination. The pathologic findings were non-specific ulcers with necrotizing vasculitis in the vulva and with suspicious vasculitis in the esophagus. So she was diagnosed to have a Behcets disease and was treated with steroid and sulfasalazine. In this study we report a case of esophageal involvement of Behcet's disease with a review of the literature.

BACKGROUND: Propofol is a good induction agent. but it has a disadvantage of pain on intravenous injection. Pretreatment of metoclopramide or lidocaine have been reported to reduce pain on injection. thus, we have evaluated the quantity and quality of anagesic effect of metoclopramide and lidocaine. We observed differences in quality of pain according to venous cannula sizes and intravenous injection sites as well as nausea and vomiting in the postoperative state. METHODS: Eighty patients scheduled for an elective operation by general anesthesia were chosen according to ASA (I or II) and divided into four groups randomly. Each group was injected through venous cannulas with normal saline (control group), metoclopramide 5 mg (group 1), metoclopramide 10 mg (group 2), or 2% lidocaine 40 mg (group 3) respectively. Then, propofol was injected of a 2 mg/kg dose with 0.5 ml/sec to all groups and we asked questions about injection pain after 10 seconds. RESULTS: Pain relief was shown in all groups compared with the control. but metoclopramide 10 mg and lidocaine 40 mg pretreatment groups showed significant pain reief. Pain was relieved significantly when the drug was injected in the antecubital area. Postoperative nausea and vomiting were not observed. CONCLUSIONS: Metoclopramide 10 mg or lidocaine 40 mg pretreatment to induction by propofol revealed a good analgesic effect for propofol injection pain.

BACKGROUND: Distal humerus intercondylar fractures are intra-articular and comminuted fractures involving soft tissue injury. As distal humerus is triangle-shaped, parallel plating coupled with articular fixation would be suitable for bicolumn restoration in treatment of distal humerus intercondylar fracture. METHODS: This study included 38 patients (15 males and 23 females) who underwent olecranon osteotomy, open reduction and internal fixation with the triangle-shaped cannulated screw and parallel locking plates (triangular fixation technique). Functional results were assessed with the visual analog scale (VAS) scores, Mayo elbow performance (MEP) scores and Disabilities of the Arm, Shoulder and Hand (DASH) questionnaires. Anteroposterior and lateral elbow radiographs were assessed for reduction, alignment, fracture union, posttraumatic arthrosis, and heterotopic ossification, and computed tomography (CT) scans were used to obtain more accurate measurements of articular discrepancy. RESULTS: All fractures healed primarily with no loss of reduction. The mean VAS, MEP, and DASH scores of the affected elbow were not significantly different from those of the unaffected elbow (p = 0.140, p = 0.090, and p = 0.262, respectively). The mean degree of flexion was significantly lower in the affected elbow than in the unaffected elbow, but was still considered as functional (p = 0.001, > 100degrees in 33 of 38 patients). Two cases of articular step-offs (> 2 mm) were seen on follow-up CT scans, but not significantly higher in the affected elbow than in the unaffected elbow (p = 0.657). Binary logistic regression analysis revealed that only Association for Osteosynthesis (AO) type C3 fractures correlated with good/excellent functional outcome (p = 0.012). Complications occurred in 12 of the 38 patients, and the overall reoperation rate for complications was 10.5% (4 of 38 patients). CONCLUSIONS: Triangular fixation technique for bicolumn restoration was an effective and reliable method in treatment of distal humerus intercondylar fracture. This technique maintained articular congruency and restored both medial and lateral columns, resulting in good elbow function.

BACKGROUND AND OBJECTIVES: Ventricular fibrillation (VF) can inadvertently occur during electrophysiologic study (EPS) or catheter ablation. We investigated the incidence, cause, and progress of inadvertently developed VF during EPS and catheter ablation. SUBJECTS AND METHODS: We reviewed patients who had developed inadvertent VF during EPS or catheter ablation. Patients who developed VF during programmed ventricular stimulation to induce ventricular tachycardia or VF were excluded. RESULTS: Inadvertent VF developed in 11 patients (46.7+/-9.3 years old) among 2624 patients (0.42%); during catheter ablation for atrial fibrillation (AF) in nine patients, frequent ventricular premature beats (VPBs) in one, and Wolff-Parkinson-White (WPW) syndrome were observed in one. VF was induced after internal cardioversion in six AF patients due to incorrect R-wave synchronization of a direct current shock. Two AF patients showed spontaneous VF induction during isoproterenol infusion while looking for AF triggering foci. The remaining AF patient developed VF after rapid atrial pacing to induce AF, but the catheter was accidentally moved to the right ventricular (RV) apex. A patient with VPB ablation spontaneously developed VF during isoproterenol infusion. The focus of VPB was in the RV outflow tract and successfully ablated. A patient with WPW syndrome developed VF after rapid RV pacing with a cycle length of 240 ms. Single high energy (biphasic 150-200 J) external defibrillation was successful in all patients, except in two, who spontaneously terminated VF. The procedure was uneventfully completed in all patients. At a mean follow-up period of 17.4+/-15.5 months, no patient presented with ventricular arrhythmia. CONCLUSION: Although rare, inadvertent VF can develop during EPS or catheter ablation. Special caution is required to avoid incidental VF during internal cardioversion, especially under isoproterenol infusion.

Objective:
To evaluate the construction reproducibility of a composite tooth model (CTM) composed of an intraoral-scanned crown and a cone-beam computed tomography (CBCT)-scanned root.
Methods:
The study assessed 240 teeth (30 central incisors, 30 canines, 30 second premolars, and 30 first molars in the maxillary and mandibular arches) from 15 young adult patients whose pre-treatment intraoral scan and CBCT were available. Examiner-Reference (3 years’ experience in CTM construction) and Examiners-A and Examiner-B (no experience) constructed the individual CTMs independently by performing the following steps: image acquisition and processing into a three-dimensional model, integration of intraoral-scanned crowns and CBCT-scanned teeth, and replacement of the CBCT-scanned crown with the intraoral-scanned crown. The tooth axis angle in terms of mesiodistal angulation and buccolingual inclination of the CTMs constructed by the three examiners were measured. To assess the construction reproducibility of CTMs, intraclass correlation coefficient (ICC) assessments were performed.
Results:
The ICC values of mesiodistal angulation and buccolingual inclination among the 3 examiners showed excellent agreement (0.950–0.992 and 0.965–0.993; 0.976–0.994 and 0.973–0.995 in the maxillary and mandibular arches, respectively).
Conclusions
The CTM showed excellent construction reproducibility in mesiodistal angulation and buccolingual inclination regardless of the construction skill and experience levels of the examiners.

Objective:
To investigate the distribution, side involvement, phenotype, and associated anomalies of Korean patients with craniofacial clefts (CFC).
Methods:
The samples consisted of 38 CFC patients, who were treated at Seoul National University Dental Hospital during 1998–2018. The Tessier cleft type, sex, side involvement, phenotype, and associated anomalies were investigated using nonparametric statistical analysis.
Results:
The three most common types were #7 cleft, followed by #0 cleft and #14 cleft. There was no difference between the frequency of male and female. Patients with #0 cleft exhibited nasal deformity, bony defect, and missing teeth in the premaxilla, midline cleft lip, and eye problems. A patient with #3 cleft (unilateral type) exhibited bilateral cleft lip and alveolus. All patients with #4 cleft were the bilateral type, including a combination of #3 and #4 clefts, and had multiple missing teeth. A patient with #5 cleft (unilateral type) had a posterior openbite. In patients with #7 cleft, the unilateral type was more prevalent than the bilateral type (87.0% vs. 13.0%, p < 0.001). Sixteen patients showed hemifacial microsomia (HFM), Goldenhar syndrome, and unilateral cleft lip and palate (UCLP). There was a significant match in the side involvement of #7 cleft and HFM (87.5%, p < 0.01). Patients with #14 cleft had plagiocephaly, UCLP, or hyperterorbitism. A patient with #30 cleft exhibited tongue tie and missing tooth.
Conclusions
Due to the diverse associated craniofacial anomalies in patients with CFC, a multidisciplinary approach involving a well-experienced cooperative team is mandatory for these patients.

BACKGROUND: Coronary angiography have become important and integral components in the investigation of patients with cardiovascular disease. Technical improvement combined with an increased need of coronary angiography, and efforts to decrease the length of inpatient hospital stay have prompted the development of outpatient coronary angiography. In this study, we compared the procedure-related complications and costs of inpatient and outpatient coronary angiography when performed at the same institution. In addition, we attempted the coronary angiography as outpatient setting in patients with unstable angina, old age, and anticoagulation therapy, who have been regarded as contraindication for outpatient procedure. METHODS: Diagnostic coronary angiography was performed in 199 cases as inpatient setting, and 225 cases as outpatient setting at Korea University Guro Hospital From January through July 1996. There was no significant difference in sex, age, risk factor, blood pressure, cholesterol level, and ejection fraction. We did not give the heparin during the procedure and, use the Judkins' method in all patients. After the procedure, pressure dressing was done with compressor device for 15 minutes, then sandbag was applied on the puncture site. In outpatient, they took bed rest for 6 hours in one-day care room. RESULTS: 1) In the inpatient group, there were 6 cases(3.0%) of catheterization-related complication, and there were 7 cases(3.1%) of complication in the outpatient group. There was no major complication in both groups, such as death, myocardial infarction, stroke, and perforation of heart and great vessels. In the inpatient group, 2 cases of arrhythmia, 3 cases of hematoma at puncture site, and 1 case of femoral artery pseudoaneuryrsm occurred. In the outpatient group, 2 cases of arrhythmia, 1 case of hematoma at puncture site, 2 cases of skin rash, 1 case of acute febrile reaction, and 1 case of femoral artery dissecting aneurysm developed. There was no significant difference in the rate of complications between two groups(p=0.947). 2) In the outpatient group, there were 28 cases of unstable angina, 6 cases of old age more than 75 years, and 5 cases of anticoagulant has been taken. No catheterization-related complication occurred in those groups. 3) The costs and duration of hospital stay in the inpatient group were won480,230+/-86,800 and 50.3+/-12.3 hours and those in the outpatient group were won276,870+/-32,050 and 8.3+/-1.2 hours. There was significant difference between two groups in the costs and duration of hospital stay(p<0.01, p<0.01). CONCLUSIONS: Outpatient coronary angiography could be done safely with low complication rate, and could reduce the costs and hospital stay. For high risk group such as unstable angina, old age, and anticoagulation therapy, there was no complication in this study, but more experiences and available data should be accumulated to be accepted as a general guideline.

Upper gastrointestinal bleeding occurs so rapidly that emergency measures are required to avoid exsanguination. Many diseases cause bleeding from the gastrointestinal tract. Patients with upper gastrointestinal bleeding must be quickly assessed and resuscitated. An endoscopy is the diagnostic procedure of choice because of its high rate of accuracy and immediate therapeutic potential. An endoscopy however, must be performed only following adequate resuscitation and clinical assessment of the patient. Recently, reports have described the usefulness of endoscopic O-ring band ligation in the management of upper gastrointestinal bleeding. Endoscopic O-ring band ligation is mucosal ligation using intraluminal negative pressure with an elastic O-ring. We performed an emergency endoscopy in 3 patients who had massive or recurrent episodes of upper gastrointestinal bleeding, identified as having resulted from Dieulafoy lesion and Anisakiasis. We tried to perform an endoscopic ligation using an O-ring band, and were successful in achieving hemostasis. Our conclusion is that endoscopic ligation using an O-ring band can be used effectively to control active upper gastrointestinal bleeding resulting from Anisakiasis and a Dieulafoy lesion.
