PURPOSE : The 3rd molar extraction of mandible is common in out-patient office of oral and maxillofacial surgery. And it is dynamic minor operation with changes of vital signs. most of patients are already sensitive about their dental treatment. The changes of emotion are reached to the highest level when patients is laid down to be treated on unit chair. It can be induced to undesirable accidents as to this fear. The undesirable complications are nausea, vomiting, hyperventilation, dyspnea, syncope, shock and so on. The severe changes of vital signs may influence their behavior and make serious medical malpractice or suit such as fracture of dental instruments and injury of proximal area. METHOD AND PATIENTS : A total of 99 selected normal patients were reviewed. Among this, 70 patients(43 men, 27 women with statistical significance) were included in this study. Each steps(pre-anesthesis, 5 minutes after anesthesis, just after mucogingival incision, just after tooth section, just after suture and gauze biting) were investigated for a change of a vital signs. It is analyzed to 2 categories,"Means" and "Tendency". The "Means" is the amount of vital signs changed in comparison with pre-step during operation. That means is the amount of vital changes by each step operation. Next, " Tendency" is changes of vital signs in comparison with step1 during operation. RESULT : This is the changing tendency of vital signs with time. That is active effect of fear and pain. Thus this "Means" and "Tendency" will present a sudden changes of vital signs and it can lead to more safe treatment. CONCLUSION : Thus, the purpose of this study is, through careful operation in each step, to less on patients' complication and increase trust between patient and OMFS. This study is a first article shown with the amount of "Means" and "Tendency" in vital signs, when a third molar of mandible is extracted. This study will be base study of patients with general diseases, because it selected only patients without general diseases.

Air reduction is a safe, effective, and fast initial treatment for pediatric intussusception. There is low dose radiation exposure. Factors affecting outcomes of air reduction were analyzed by reviewing the clinical features and results of treatment. A total of 399 out of 485 patients with pediatric intussusceptions were treated at the Seoul National University Children's Hospital from 1996 to 2009. All of the patients received air reduction as the first line of treatment. Clinical features such as gender, age, seasonal variation, symptoms, signs, types, pathologic leading point, and treatment results including success rate, complication, recurrence, NPO time, and duration of hospitalization were reviewed. The Pearson chi-square, student T-, and logistic regression tests were used for statistical analysis. P-value less than 0.05 was considered to be statistically significant. The prevalent clinical features were: male (65.4 %), under one-year of age (40.3 %), ileocolic type (71.9 %), abdominal pain (85.4 %), and accompanying mesentery lymph node enlargement (2.2 %). The overall success rate for air reduction was 78.4 % (313 of 399 patients), and the perforation rate during reduction was 1.5 %. There were 23 recurrent cases over 21.6 months. All were successfully treated with re-do air reduction. Reduction failures had longer overall NPO times (27.067hrs vs. 43.0588hrs; p=0.000) and hospitalization durations (1.738d vs. 6.975d; p=0.000) compared to the successful cases. The factors affecting success rates were fever (p=0.002), abdominal distension (p=0.000), lethargy (p=0.000) and symptom duration (p=0.000) on univariate analysis. Failure rates were higher in patients with symptom durations greater than 24 hours (p=0.023), and lethargy (p=0.003) on multivariate analysis. Air reduction showed high success rates and excellent treatment outcomes as the initial treatment for pediatric intussusception in this study. Symptom duration and lethargy were significantly associated with reduced success rates.

Pancreatic tumors in children are relatively rare, and their prognosis differs from that in adults. The purpose of this study is to examine the clinical characteristics, treatment, and prognosis for children with pancreatic tumors. We retrospectively reviewed the medical records of children under 15 years of age with pancreatic tumors who were treated surgically at Asan Medical Center between January 1992 and November 2009. There were 16 patients, fourteen of whom were pathologically diagnosed with solid pseudopapillary tumor. The other two patients were diagnosed with pancreatoblastoma and acinar cell carcinoma, respectively. Six patients of the 16 patients (38 %) were male, and there was a male-to-female ratio of 1:1.6. The initial presentations were upper abdominal pain in eight patients (50 %), palpable abdominal mass in three, and vomiting in one. Four patients were diagnosed incidentally. Six patients' tumors were located in the pancreatic head, six in the pancreatic body, and four in the pancreatic tail, respectively. The surgical procedures performed included distal pancreatectomy (n=7, 44 %), median segmentectomy (n=3), enucleation (n=3), pancreaticoduodenectomy (n=2), and pylorus-preserving pancreaticoduodenectomy (n=1). Three patients underwent laparoscopic surgery. The median tumor size was 6.5 cm (1.8~20 cm). Early surgical complications included pancreatic fistula (n=4), bile leakage (n=1), and delayed gastric emptying (n=1). A late complication in one patient was diabetes. The median follow-up period was five years and four months, and all patients survived without recurrence. While pancreatic tumors in adults have a poor prognosis, pancreatic tumors of childhood are usually curative with complete resection and thus have a favorable prognosis.

Untreated massive hemoptysis, especially in patients with tuberculous-destroyed lung, is a serious complication resulting in considerable morbidity and mortality. We report a case of a patient who had active tuberculosis and a destroyed left lung with massive bleeding. He was transferred to our clinic with intubation of a right-sided Robertshaw double lumen tube and right upper lobe collapse likely due to tube malposition that was presented on chest X-ray. Because hemoptysis had persisted after bronchial arterial embolizaton, we replaced the double lumen tube with a conventional endotracheal tube and inserted an endobronchial blocker into the left main bronchus through an endotracheal tube guided by bronchoscopy to prevent aspiration of blood into the right lung. Left pneumonectomy was performed and hemotpysis was ceased. We suggest that the use of an endobronchial blocker followed by surgery may be a safe and effective modality of treatment in patients with persistent bleeding after bronchial arterial embolization.

Paclitaxel has been widely used for treating many solid tumors. Although colonic toxicity is an unusual complication of paclitaxel-based chemotherapy, the reported toxicities include pseudomembranous colitis, neutropenic enterocolitis and on rare occasions ischemic colitis. $Genexol-PM^{(R)}$, which is a recently developed cremophor-free, polymeric micelle-formulated paclitaxel, has shown a more potent antitumor effect because it can increase the usual dose of paclitaxel due to that $Genexol-PM^{(R)}$ does not include the toxic cremophor compound. We report here on a case of a 57-year-old man with advanced non-small cell lung cancer and who developed ischemic colitis after chemotherapy with $Genexol-PM^{(R)}$ and cisplatin. He complained of hematochezia with abdominal pain on the left lower quadrant. Colonoscopy revealed diffuse mucosal hemorrhage and edema from the sigmoid colon to the splenic flexure. After bowel rest, he recovered from his symptoms and the follow-up colonoscopic findings showed that the mucosa was healing. Since then, he was treated with pemetrexed monotherapy instead of a paclitaxel compound and platinum.

Purpose: This study was performed retrospectively to evaluate clinical outcomes of distal metatarsal osteotomy using bio-compression screw as the joint preservation method for advanced hallux rigidus. Materials and Methods: Eleven cases were followed up for more than 1 year after distal metatarsal dorsal wedge osteotomy for advanced hallux rigidus. The clinical evaluation was performed according to the American Orthopaedic Foot and Ankle Society (AOFAS) score and patient's satisfaction score. The range of motion, and the period to return to running exercise, tip-toeing gait, squatting, walking down the stairs were evaluated. As the radiographic evaluation, the interval of $1^{st}$ MTP (metatarsophalangeal) joint space and the period to union were measured. Results: The AOFAS hallux score had improved significantly from preoperative average 50.7 points to 87.6 points at the last follow-up (p=0.005). The subjective satisfaction score was average 90.6 points. There were no case of subsequent fusion or additional operation, and no complication associated with bio-compression screw. The period to return to running exercise, tip-toeing gait, squatting, walking down the stairs were average of 24.8 weeks, 20.4 weeks, 16.8 weeks, 18.5 weeks respectively. Dorsiflexion of $1^{st}$ MTP joint had improved significantly from preoperative average $17.5^{\circ}$ to $44^{\circ}$ (p<0.001). All cases achieved union of osteotomy site, and the period to union was average 10.4 weeks. The interval of $1^{st}$ MTP joint space had improved significantly from preoperative average 1.2 mm to 3.5 mm (p=0.014). Conclusion: Distal metatarsal osteotomy using bio-compression screw seems to be one of effective treatment methods for advanced hallux rigidus, because of restoration of the first MTP joint motion, and reliable pain relief, and needlessness of hardware removal.

Purpose: The rate of fistulas occuring followed by resection of oral cavity, oropharyngeal, hypopharyngeal, and laryngeal cancer are reported to be 9 ~ 23% according to various documents. Neglected treatment of the fistula can result in a setback in proper treatment with restrictions in oral intake leading to delayed return to daily life. Furthurmore, in severe cases, it may injure important vessels and adjacent structures of the neck area. The author reviewed previously reported cases of treatment methods for fistulas recurring after diverse head and neck operations and with sharing the treatment experiments of our patients, we tried to present a treatment algorism for different fistula types. Methods: Our study was based on retrograde analysis of 64 patients who were clinically diagnosed with fistula after operation for cancer of the head and neck from 1997 to 2008 at Severance Hospital. Their primary sites of cancer were 8 oral cavity, 22 oropharynx, 25 hypopharynx, and 9 larynx. The patients were aged 45 to 75 years and the male to female ratio was 11 to 1. The patient's operation records and progress notes were evaluated for determination of degree of fistula and treatment methods. Results: Most fistulas were clinically suspected after postoperative 5 days and symptoms noted for detection of the fistula were erythema, purulent discharge, edema, tenderness, and fluctuation. The fistula was definitely diagnosed at postoperative 2 weeks with barium test and treatment method ranging from conservative management to operative procedure were applied to each patients. Total 21 patients were managed with conservative protocol. In 15 cases, direct repair of the fistula was done and more stable repair of the fistula was possible with using of TachoComb$^{(R)}$. Pharyngostoma was performed in 14 patients. Among them, 4 patients healed spontaneously, 5 patients were taken direct closure, 4 patients were taken pectoralis major musculocutaneous flap, and one patient was taken esophageal transfer. The other 14 patients were taken 11 pectoralis major musculocutaneous flaps and 3 free flaps without pharyngostoma formation. Conclusion: Fistula is a troublesome complication resulting after resection of head and neck cancer. Early detection and adequate treatment according to the period and condition of the fistula may prevent further complications and reduce the pain of the patient.

Background: Open heart surgery using cardiopulmonary bypass (CPB) is considered one of the most frequent surgical procedures in which acute kidney injury (AKI) is a frequent and serious complication. The aim of the present study was to evaluate the efficiency of neutrophil gelatinase-associated lipocalin (NGAL) as an early AKI biomarker after CPB in cardiac surgery (CS). Methods: Thirty-seven adult patients undergoing CS with CPB were included in this retrospective study. They had normal preoperative renal function, as assessed by the creatinine (Cr) level, NGAL level, and estimated glomerular filtration rate. Serial evaluation of serum NGAL and Cr levels was performed before, immediately after, and 24 hours after the operation. Patients were divided into two groups: those who showed normal immediate postoperative serum NGAL levels (group A, n=30) and those who showed elevated immediate postoperative serum NGAL levels (group B, n=7). Statistical analysis was performed using Statistical Package for the Social Sciences version 18. Results: Of the 37 patients, 6 (6/37, 16.2%) were diagnosed with AKI. One patient belonged to group A (1/30, 3.3%), and 5 patients belonged to group B (5/7, 71.4%). Two patients in group B (2/7, 28.5%) required further renal replacement therapy. Death occurred in only 1 patient (1/37, 2.7%), who belonged to group B. Conclusion: The results of this study suggest that postoperative plasma NGAL levels can be used as an early biomarker for the detection of AKI following CS using CPB. Further studies with a larger sample size are needed to confirm our results.
