The frequency of infected non-union of long bones is increased due to an increment of open fractures, and so its treatment give orthopedic surgeons a rather difficult obstacles. In treatment of twenty two cases of trouble infected non-union that we undergone from march, 1980 to decmber, 1984, we use some principles of treatment, that is, rigid osteosynthesis, autogenous cancellous bone graft and irrigation system, so we obtain the good results. The conclusion are as follows: 1. All cases were men, and they occured more commonly in young adults, 10 cases (45.5%) were in third decade. 2. The fractures of the tibia showed a high frequency of infected non-union, 17 cases (77.3%) were the fractures of the tibia. 3. All cases showed a grave comminution initially, of them 18 cases (81.8%) were open fractures. 4. The most common causative organism of an infection was staphylococcus aureus, 14 cases(63.6%), showed that organism in pus culture. 5. Using the above mentioned principles of treatment, bony union was achieved in 18 cases for average 5 months except 2 cases losting the follow-up and 2 cases undergoing the below knee amputation.

Three rare tumors of the oral cavity are presented. Lingual chondromas, approximately twenty to thirty cases appear to have been reported since the lesion was first described by Berry in 1892, which are usually seen on the lateral borders in the anterior two thirds of the tongue, while the ventral surface and the posterior third are rarely involved. Chondromas of the tonsil are of very rare occurrence, which are thought to arise as a result of metaplasia, rather than from embryonic rests, with chronic fibrosing inflammation being the inciting factor. Because of its rarity, the following cases of chondroma of the tongue and tonsil are being added to small list of such case reported in the literature.

Twenty species representing five genera of arbuscular mycorrhizal fungi were isolated from twenty-four soil samples of the rhizosphere of the family Gramineae in Paekryung and Daecheong islands. A few species such as Glomus invermaius, G. marcrocapus var. marcrocarpus and Scutellospora coralloidea were recorded for the first time in Korea. The number of spores per 10g of soil was in the range of 8~337 in Paekryung and 16~349 in Daecheong island, respectively. The number of species per 10g of soil was 2~8 species in Paekryung and 2~7 species in Daecheong, respectively. Among them, G. macrocarpus var. macrocarpus was the most abundant species in both islands. The species diversity and evenness were almost similar in Paekryung and Daecheong Islands. Based on the host plants in two islands, the species diversity showed the highest value of 1.63 in Ischaemum crassipes, whereas the eveuness of species showed the lowest value of 0.35 in Eragrostis ferraginea.

Fibrous dysplasia is a benign bone lesion characterized by the replacement of the normal substance of the interior of the bone by the fibro-osseous connective tissue exhibiting varying degree of osseous metaplasia histologically. In the head and neck, the most frequently involved area is the maxilla. We present 29 year-old male with diffuse swelling in the right frontal area, headache and nasal obstruction persisting for 2 years. Computed tomography scan of the paranasal sinus revealed irregular hyperdense mass arising from the right frontal sinus. The interfrontal septum was deviated to the left side by the mass. There was no evidence of invasion through and into the orbit and the cranial vault. Bilateral osteoplastic surgery of the frontal sinus was done. The mass was originated from the posterior wall of the right frontal sinus and expanded to the anterior wall. It's margin was poorly defined with adjacent normal osseous tissues, and it was removed by drilling and curettage. Left nasofrontal duct was well preserved, whereas right nasofrontal duct was obstructed by the mass. The pathologic finding consisted of an abundance of fibroblasts in interlacing bundles or whorls, connective tissue stroma of high vascularity, and islets of irregular trabeculae of new bone.

BACKGROUND AND PURPOSE: This purpose of this research is to study the prevalence of habitual snoring and the association between snoring and cephalo-anthropometric analysis in Korean population. MATERIAL AND METHOD: Four thousand and two hundred twenty four subjects (male: 2277, female: 1947), aged between 18~85 (mean age male: 45.3, female: 44.0), were recruited through home visits and interviewed by well-trained investigators. RESULTS: Three hundred fifty two male subjects (15.5%) and one hundred sixty two female subjects (8.32%) exhibited habitual snoring. Age, weight, and body mass index (BMI) were significantly higher in the snoring group compared to those who dont snore habitually. Using a stepwise variable selection method of multiple logistic regression analysis, we found independent factors as being significant for males and females of the snoring groups. For males, the factors were BMI (p<0.001, OR=1.18 CI: 1.12~1.25), mandibular angle (p<0.001, OR=0.97 CI: 0.96~0.98), and abdominal girth (p<0.001, OR=1.04, CI: 1.02~1.06. For females, they were abdominal girth (p=0.031, OR=1.03, CI: 1.00~1.05), neck girth (p=0.003, OR=1.12, CI: 1.04~1.21), age (p=0.0002, OR=1.02 CI: 1.01~10.3), and BMI (p=0.0007, OR=1.11 CI: 1.05~1.18). CONCLUSION: We found that BMI, gonion angle and abdomen girth in male and abdominal girth, neck girth, age, BMI in female were the significant factors affecting the severity of snoring in Korean population.

Idiopathic sudden sensorineural hearing loss(ISHL) is defined as an abrupt onset of sensorineural hearing loss without definite cause. The causes of sudden sensorineural hearing loss have not determined with precision until recently, but viral infections and vascular insufficiencies, such as vascular spasm, occlusion of sludging of erythrocytes were considered as major factors. The treatment has not been determined with precision until recently. But recently, as a effective regimen, diatrizoate meglumine(Hypaque) was introduced that fills the broken membrane pores and activated the sodium pump to restore the normal DC potential. The purpose of this study was to evaluate the effectiveness of a regimen for the treatment of the sudden sensorineural hearing loss with Hypaque, steroid and bed rest by retrospective review.

BACKGROUND/AIMS: Endoscopic biliary drainage (EBD) has been used effectively as the palliative treatment for malignant biliary obstruction. In high grade strictures, endoscopic stenting can be achieved by dilating devices such as dilating or balloon catheters. Subgroup of malignant biliary obstructions are too stenotic to allow passage of plastic or metal stents. In cases of failure of conventional stenting, we evaluated the efficacy and safety of the 7-Fr Soehendra stent retriever (SSR) used as a dilator. METHODS: From January 1999 to September 2001, 14 patients with malignant pancreaticobiliary stirictures (2 pancreatic, 12 biliary) that could not be traversed with plastic or metal stents, underwent stricture dilation with SSR. An endoscopic sphincterotomy was performed and a guide wire was inserted beyond the stricture. Then the SSR was introduced over the guide wire via duodenoscope. Then the stricture was traversed by torquing the SSR clockwise while pushing it. The SSR was removed and then the plastic or metal stents were inserted above the stricture. RESULTS: Of the 14 patients, 13 patients (93%) underwent successful stenting using SSR. Symptom relief was observed in all patients after endoscopic biliary stenting. One patient (7%) went on to percutaneous biliary drainage because we failed to insert the metal stent into the stenotic left hepatic duct after traversing the stricture with SSR. There were no significant complications such as bile duct or duodenal perforation and bleeding. CONCLUSIONS: The Soehendra stent retriever is useful and safe for dilation with subsequent stent placement of malignant pancreaticobiliary stirictures resistant to conventional stenting. However, this device may be difficult to pass a tortuous or small-diameter hilar stricture.

BACKGROUND: The prevalence of anxiety disorders has been increasing in South Korea, with recent studies reporting anxiety disorders as the most common mental disorder among all South Korean females. Anxiety disorders, which are independent risk factors of suicidal ideation and suicide attempts, are significantly correlated with productivity loss, high medical costs, impaired work performance, and frequent worker absence, and thus are potentially serious problems affecting the health of South Korean female workers. In previous studies, anxiety disorders were shown to have a significant correlation with occupational stress. This study seeks to examine the prevalence of anxiety symptoms as well as the relationship between occupational stress and anxiety symptoms among South Korean female manufacturing workers. METHODS: A structured self-reported questionnaire was administered to 1,141 female workers at an electrical appliance manufacturing plant. The questionnaire collected data on general characteristics, health behaviors, sleep quality, job characteristics (shift work, shift work schedule, and job tenure), occupational stress, and anxiety symptoms. Sleep quality was measured using the Pittsburgh Sleep Quality Index, occupational stress with the Korean Occupational Stress Scale-Short Form (KOSS-SF), and anxiety symptoms with the Korean version of the Beck Anxiety Inventory. A chi square test was conducted to determine the distribution differences in anxiety symptoms based on general characteristics, health behaviors, job characteristics, and sleep quality. A linear-by-linear association test was used to determine the distribution differences between anxietysymptoms and the levels of occupational stress. Last, logistic regression analysis was used in order to determine the association between occupational stress and anxiety symptoms. RESULTS: The prevalence of anxiety symptoms was 15.2 %. In the multivariate logistic regression analysis that adjusted for sleep quality and general characteristics, a significantassociation was found for those with anxiety disorders; the odds ratios (OR) were significantly higher the greater the total KOSS-SF score (moderate-risk group OR=2.85, 95 % CI=1.79-4.56; high-risk group OR=5.34, 95 % CI=3.59-7.96). In addition, excluding insufficient job control, all other KOSS-SF subscales were significantly associated with anxiety symptoms, and a relatively high OR was seen in the high-risk group for job demand (OR=3.19, 95 % CI=2.27-4.49), job insecurity (OR=4.52, 95 % CI=2.86-7.13), and occupational culture (OR=4.52, 95 % CI=2.90-7.04). CONCLUSION: There was a significant association between anxiety symptoms and occupational stress stemming from the psychosocial work environment among these South Korean female manufacturing workers. Future longitudinal studies are needed to examine the association between the occupational stress caused by the psychosocial work environment and the incidence of anxiety disorders and anxiety symptoms. Furthermore, intervention programs that aim to address the prevalence of anxiety symptoms and improve the psychosocial work environment, especially for younger female manufacturing workers, are needed.
