Purpose: Sclerosing lipogranuloma is an unusal benign condition of the genitalia following injections into the genitalia with exogenous paraffin or mineral oil. A few cases have been reported in which sclerosing lipogranuloma of the lid was caused by paraffin-containing ointment plugs after the endonasal sinus surgery. A 52-year-old man presented with a painless hard mass of the right lower lid after the MRI scan at the Ophthalmology department. Nine months before, he had undergone right maxilla sinus surgery through the oral incision. And he was also gotten nasal packing with Vaseline gauze after the surgery. Methods: The round shaped two masses in the Right lower lid were approximately $1.0{\times}1.0cm$ in size. There were no size or color change, bleeding and ulceration. The MRI scan showed a suspicious part of an abscess of benign tumor. Also, He was planned cyst remove through the endonasal surgery due to the mucoid cyst in the right maxillary sinus in the ENT dept. Under the general anesthesia, the patient underwent surgical excision through a subcilliary incision with endonasal sinus surgery. The masses were in deep subcutaneous orbital fat with no connection with right maxillary sinus. Results: The masses were excised $2.1{\times}0.7cm$ in size including surrounding necrotic fatty tissue. Histopathological diagnosis was 'sclerosing lipogranuloma' due to paraffin or similar substance with fat necrosis and cystic change. This tissue was positive in PAS, S-100, CD68 reaction. Conclusion: It is extremely rare to find a granulomatous orbital lesion arising to a endonasal surgery. In conclusion, if sclerosing lipogranuloma is suspected excisional biopsy should be undertaken. Surgery should be reserved for recurrent or refractory cases when steroids have failed as first-line treatment at the 6-month follow-up examination, There was no complication or recurrence.

Background: Oral mucositis is a common complication of anticancer chemotherapy. The sequelae of this consist of an increased risk of infection, moderate to severe pain, compromised oral function, and bleeding. This study was performed to evaluated the effects of the He-Ne laser and the Ga-Al-As laser on oral mucositis caused by anticancer chemotherapy in pediatric patients. Methods: There were 3 cases of osteosarcoma and 6 cases of leukemia. All patients received He-Ne laser (632.8 nm wavelength, power 60 mW) application on 400-600 Hz scanning for 5-20 minutes and Ga-Al-As laser (904 nm wavelength, power 40 mW) application by fiberoptic hand piece placed in immediate proximity to the tissue without direct contact with it for 30 seconds per point for 5 days per week. During the application patients wore wavelength-specific dark glasses and were instructed to keep their eyes closed. Results: The mean number of treatments with oral intake was $4.89{\pm}0.64$. The mean number of total treatments was $9.44{\pm}2.59$. There were no significant side effects during and after the laser treatments. Conclusions: He-Ne laser and Ga-Al-As (IR) laser treatment were well tolerated and reduced the severity and duration of chemotherapy-induced oral mucositis in pediatric oncologic patients.

Objective : The case fatality rate of nonlesional intracerebral hemorrhage (n-ICH) was high and not changed. Knowing the causes is important to their prevention; however, the reasons have not been studied. The aims of this study were to determine the cause of death, to improve the clinical outcomes. Methods : We retrospectively analyzed consecutive cases of nonlesional intracerebral hemorrhage in a prospective stroke registry from January 2010 to December 2010. Results : Among 174 patients ($61.83{\pm}13.36$, 28-90 years), 29 patients (16.7%) died during hospitalization. Most common cause of death was initial neurological damage (41.4%, 12/29). Seventeen patients who survived the initial damage may then develop various potentially fatal complications. Except for death due to the initial neurological sequelae, death associated with immobilization (such as pneumonia or thromboembolic complication) was the most common in eight cases (8/17, 47.1%). However, death due to early rebleeding was not common and occurred in only 2 cases (2/17, 11.8%). Age, initial Glasgow Coma Scale, and diabetes mellitus were statistically significant factors influencing mortality (p<0.05). Conclusion : Mortality of n-ICH is still high. Initial neurological damage is the most important factor; however, non-neurological medical complications are a large part of case fatality. Most cases of death of patients who survived from the first bleeding were due to complications of immobilization. These findings have implications for clinical practice and planning of clinical trials. In addition, future conduct of a randomized study will be necessary in order to evaluate the benefits of early mobilization for prevention of immobilization related complications.

Background: Pyogenic granuloma (PG) is a benign vascular lesion of the mucosa and skin. Recent studies of the epidemiology of PG are rare. We aimed to retrospectively analyze characteristics of PG cases in South Korea. Methods: We reviewed the medical records of 155 patients treated for PG between March 2005 and May 2014. The male-to-female ratio was 1:1.2 (70 males, 85 females). The mean age of patients was 35.3 years. Results: A high occurrence was observed in the first and third decades in males, and the fourth to fifth decades in females. There was a statistically significant difference between genders according to age group (p<0.05). The average lesion diameter was $0.84{\pm}0.46cm$ (long axis). The most frequently involved site was the face (n=47). Bleeding was the primary complication (n=41). PG was mostly treated with excisional biopsy (n=74). The recurrence rate was 7.7% (n=12). Conclusion: We concluded that most common site of PG was the face, the age of female with PG is higher than previous studies, and finger is associated with trauma more than other sites. The most recent epidemiological information on PG of this study will support the treatment and diagnosis of PG and future research objectives.

In the presence of acute pericoronitis of mandilbular third molar, antibiotic therapy and early incision and drainage are the method of choice, followed by definitive surgical extraction of the tooth as soon as it becomes subacute. If excision of the overlying tissues is decided on, it should be done adequately. All overlying tissues must be throughly excised, and the crown portion of the unerupted tooth should be completely exposed. After excision has been completed, the wound should be managed with a surgical dressing. This should be allowed to remain approximately 7 days. And then, surgical extraction of the impacted mandibular third molar can be done usually. In this operation, there are many complications, such as, postoperative bleeding, infection, trismus, dysphasia and paresthesia. The surgeon are discredited and medicolegal problem may be occurred in the presence of many distressed complications. Therefore, the relatively nonsurgical treatment is the method of choice. So, authors selected the conservative treatment methods of incision and drainage, primary endodontic drainage, operculectomy without surgical extraction of the mandibular third molars. The results were more favorable without the postoperative complication in Wonju old offender prison.

Purpose: The proper reconstructive technique after a partial gastrectomy for an adenocarcinoma of the stomach is often debated, but few data exist to clarify the issue. The aim of this study was to compare retrospectively the early postoperative results and complications after different anastomoses used during a partial gastrectomy for a gastric adenocarcinoma. Materials and Methods: We reviewed the hospital records of 218 patients who had undergone a subtotal gastrectomy for gastric cancer at Chosun University Hospital between January 1997 and July 2000. Of the 218 subtotal gastrectomies performed with curative intent, 127 reconstructions were Billroth I gastrectomies and 91 were Billroth II gastrectomies. The following data were analyzed: age, sex, tumor size, gastric resection margin, timing of removal of the nasogastric tube, first bowel movement, resumption of oral feeding, and postoperative complications. Results: The timing of removal of the nasogastric tube was significantly earlier in the Billroth Igroup than in the Billroth II group ($27.9\pm13.9$ hours and $69.7\pm68$ hours, respectively)(P<0.05). Resumption of oral feeding was possible on day $4.6\pm1.5$ in the Billroth I group and on dsy $5.2\pm1.5$ in the Billroth II group (P<0.05). There were no anastomotic leakage, postoperative bleeding, and postoperative mortality among the patients in either group. Conclusions: the Billroth lgastrectomy should be considered for patients undergoing a partial gastric resection for gastric cancer due to its physiological benefits and acceptable rate of complication.

Surgical intervention for pumlmonary tuberculosis has been controverted for last several decades. Although it is widely held that the chemotherapy is the best modality for treatment of pulmonary tuberculosis, surgical intervention has still some roles in well elected circumstance. At the National Kongju Tuberculosis Hospital in Korea, we performed a retrospective case Cohort study through the regular follow-up of 463 cases, who underwent the surgical intervention for pulmonary tuberculosis between January 1986 and April 1990. The results were as follows: 1) The male to female ratio was 1.8:1 and 84.4% of the patients were between 20 and 49 years of age. 2) According to the NAT classification, 6 cases (1.3%) were minimal, 216 (46.7%) moderately advanced and 241 (52%) far advanced. 3) One hundred and thirty four cases (28.9%) had the treatment history of 5 to 10 years and 129 cases (27.9%) of 3 to 4 years. 4) As for the pathologic entities, 172 cases (37.1%) had the totally destroyed lung and 137 (29.6%) destroyed lobe or segment. 5) A total of 238 cases (51.4%) underwent pneumonectomy and 153 (33.0%) lobectomy. 6) As the post-operative complications, 21 cases (4.5%) had empyema and 11 (2.4%) bleeding. The rate of complication after pneumonectomy and lobectomy was 5.8% and 3.2%, respectively. 7) Six cases (1.3%) died post-operatively. 8) Out of 238 cases with pre-operative positivity for AFB, 212 achieved the negative conversion, its rate being 89.1%. It follows from these results that although it has a limit, surgical intervention may play an important role in treating some patients with pulmonary tuberculosis.

Endoscopic submucosal dissection (ESD) was originally developed for en bloc resection of large, flat gastrointestinal lesions. Compared with endoscopic mucosal resection (EMR), ESD is considered to be more time consuming and have more complications for treatment of early esophageal carcinoma, such as bleeding, stenosis and perforation. The objective of this study was to compare the efficacy and safety of ESD and EMR for such lesions. We searched databases, such as PubMed, EMBASE, Cochrane Library and Science Citation Index updated to 2013 for related trials. In the meta-analysis, the main outcome measurements were the en bloc resection rate, the histologically resection rate and the local recurrence rate. We also compared the operation time and the incidences of procedure-related complications. Five trials were identified, and a total of 710 patients and 795 lesions were included. The en bloc and histologically complete resection rates were higher in the ESD group compared with the EMR group (odds ratio (OR) 27.3; 95% CI, 11.5-64.8; OR 18.4; 95% CI, 8.82-38.59). The local recurrence rate was lower in the ESD group (OR 0.13, 95 % CI 0.04-0.43). The meta-analysis also showed ESD was more time consuming, but did not increase the complication rate (P=0.76). The results implied that compared with EMR, ESD showed better en bloc and histologically resection rates, and lower local recurrence, without increasing the incidence of procedure-related complications in the treatment of early esophageal carcinoma.
