The lack of sufficient oral mucosa available for intra-oral reconstruction has been dealt with by the use of skin or oral mucosa grafts harvested from donor sites but grafts requires more than one surgical procedures and could cause donor site morbidity. Many investigators have attempted to increase available soft tissue by tissue engineered skin or oral mucosa replacements for clinical applications. But, reconstructed mucosa by several methods have low physical properties such as rolling and contraction. The aims of this study were to develope an in vitro experimental model that maintains an epithelial-mesenchymal interaction by organotypic raft culture, and to characterize biologic properties of three-dimensionally cultured oral mucosa embedded with Polydioxanone mesh by histological and immunohistochemical analysis. The results were as follows; 1. Oral mucosa reconstructed by three-dimensional organotypic culture revealed similar morphologic characteristics to equvalent normal oral mucosa in the point that they show stratification and differentiation. 2. The expression of cytokeratin 10/13 and involucrin in the cultured tissue showed the same pattern with normal oral mucosa suggesting that organotypic co-culture condition is able to induce cellular differentiation. 3. After insertion of polydioxanone mesh, increased tensile strength were observed. These results suggest that three-dimensional organotypic co-culture of the oral mucosa cell lines with the dermal equvalent consisting type I collagen and fibroblasts reproduce the morphologic and immunohistochemical characteristics similar to those in vivo condition. And increased physical properties by use of polydioxanone mesh will helpful for clinical applications.

Sebaceous carcinoma is an uncommon neoplasm usually associated with ocular adnexa. This malignancy may occur at any anatomic site that contains sebaceous glands. Despite the widespread anatomic distribution of sebaceous glands, extraocular sebaceous carcinoma occurs with far less frequency. We report a case of an 87-year-old Korean woman with extraocular sebaceous carcinoma treated with total excision.

BACKGROUND: The purpose of this study was to ascertain the prevalence of vitamin D deficiency and risk factors associated with mortality in patients > or =50-year-of-age with hip fractures. METHODS: A total of 489 patients > or =50-year-of-age who sustained a hip fracture from January 2010 to October 2014 were followed-up for a minimum of 1 year. Clinical and radiological outcomes were evaluated including prevalence of vitamin D deficiency. Crude mortality rates were calculated, and the effects of different risk factors on mortality were assessed. RESULTS: Vitamin D deficiency was present in 76.5% of cases (n=237). The prevalence of vitamin D insufficiency was 12.3%, and only 11.2% of patients had normal vitamin D levels. Accumulated mortality was 11% (54 patients) at 1 year. A univariate analysis showed that vitamin D deficiency (P=0.012), age (P<0.001), BMI (P<0.001), type of management (P<0.001), American Society of Anesthesiologists (ASA) score (P=0.009), pre-fracture ambulatory status (P<0.001), and osteoporosis (P<0.001) were associated with mortality. A multivariate analysis performed using a Cox proportional hazards model demonstrated that ASA score (P=0.001) and pre-fracture ambulatory status (P=0.011) were independently associated with mortality after hip fracture. CONCLUSIONS: We did not find a relationship between serum 25-hydroxy-vitamin D levels and mortality after hip fracture, although we observed a high prevalence of vitamin D deficiency and a significant association with mortality in the univariate analysis.

PURPOSE: Convulsive status epilepticus(SE) is a serious, life-threatening neurological condition that requires immediate treatment to avoid significant morbidity and mortality. Despite improvements in the diagnosis and treatment of SE in the last two decades, SE in young infancy is still associated with high morbidity and mortality. Thus, understanding the varied etiology and clinical presentation and prognosis of SE is very important for improving the methods of evaluation and treatment of this major neurological condition. METHODS: Eighty-eight cases with 53 who have been admitted to the Department of Pediatrics, Fatima Hospital during the period of July, 1992 to June, 1997 were included. We described age distribution, etiologic classification according to age, seizure type, neurologic outcome, recurrence of SE and epileptic seizure. RESULTS: SE was frequent in young infant less than 3 years of age. Major etiology of SE was acute symptomatic(34.1%) and febrile(31.8%). In the seizure type, the majority(92.1%) was generalized convulsive, many cases(69.3%) of SE were first seizures. The neurologic sequelae were found in 15.9% and mortality rate in 5.7%. The neurologic sequelae and mortality were higher in acute symptomatic. In sixty-three follow-up cases, eleven cases were epileptic seizure, eight cases were recurred SE and two cases were recurred febrile SE. CONCLUSION: SE is a life-threatening neurological condition and occurrs mostly in young infants less than 3 years of age. It requires immediate detection of etiology in SE and aggressive treatment for reducing mortality and morbidity rates.

The contour of mandibular angle is important for facial esthetics in the oriental population, because the wide and square face is thought to have had an unhappy life. A prominent mandibular angle produces a characteristics quardrangle, coase, and muscular appearance. So, uni- or bi-lateral mandibular angle reduction is usually performed. However, there is little guideline for bi-lateral angle reduction. So, this study was to investigate the pattern of Korean mandibular angle for bi-lateral mandibular angle reduction as guideline. This study was included 66 adult men and women over 19 years old who are having the normal mandibular angle. We measured the posterior border, angle, and inferior border of mandible using cephalometric view. The results of study was as followed : 1. The ratio of posterior mandible was 96.6, 97.3% in male, and 103.0, 106.0% in female. 2. The ratio of mandibular angle(R1-Go/R1-R2) was 120.2% in male, and 117.3% in female. 3. The ratio of inferior mandible(D5, 6, 7, E, F, G/D4) was 97. 3, 90.9, 79.5, 65.2, 57.8, 46.9% in male, and 98.5, 91.2, 80.5, 67.6, 59.1, 50.2 % in female. The results of this study should be useful to decide accurate amount of reduction.

Mucocele of the appendix is uncomrnon and rarely diagnosed preoperatively. The malignant rountpart-i.e. mucinous cystadenocarcinoma--has the same grross appearance and many micro scopic features in cornmon wilhe the benign form. It rnay be associated with ovarian mucinous cystadenoma of strikingly similar microscopic appearence. A serious complication is a rupture of the mucoeele resulting in pseudomyxoma peritonei. Each case of benign and malignant mucocelr of the appendix falsely diagnosecl as an oovarian tumor before laparotxumy are presented wilh a brief rieview of the literatures.

A coronary artery aneurysm was first reported by Bougon in 1812, and was able to be diagnosed during life with advance of selective coronary arteriography. We have recently seen a 62-year-old woman who had intermittent anterior chest pain and dyspnea on exertion(NYHA functional class II) and diagnosed a coronary artery aneurysm by coronary arteriography. A saccular formed coronary artery aneurysm was located at left main coronary artery at the juction of the bifurcation of LAD and left circumflex artery and it's was 2cmx2cm and it's thickness of wall was 0.5cm. After the patency and consistency of coronary arteries were confirmed,resection of aneurysm with aneurysmorrhaphy was performed.

Percutaneous biopsy is the most frequent interventional radiographic procedure. Its increased use is relatedto new imaging techniques facilitating needle placement, greater safety of fine needle and advances in cytology.CT because of its characteristic high spatial and density resolution, permits the accurate localization of anylesion in the body. Because of the ability of CT scans to precisely localize lesions and biopsy needle, along withthe delineation of adjacent structure, it is widely used in percutaneous biopsy. Sixty-six cases of CT-guidedpercutaneous fine-needle biopsy were performed in order to diagnose suspected malignant or infectious disease(49malignant and 17 infectious) over a 7-month period(June 1984 through Dec. 1984). Most of these procedures wereperformed on, but not limited to, the lung(21), liver(20), and pancreas(7). The spine and nasopharynx could alsosafely be biopsied. 4 cases of hepatic abscesses were successfully drained following insertion of drainingcatheter under the CT-guidance. The overall accuracy of both suspected malignant and infectious disease was 82%.Complication rate was low as 6%(4 cases only in thorax). Neither complication require any further intervention.Three were self-limited pneumothoraces and one was minimal hemorrhage around the needle tract.
