PURPOSE: The purposes of this article are to identify CT findings distinguishing nasal polyps, that are the most common cause of the nasal polypiod lesions, from other nasal cavity masses and to identify differential points between benign and malignant masses of nasal cavity. MATERIALS AND METHODS: We classified 567 cases of pathologically proved nasal cavity masses into 4 different groups on CT according to the sites of origin and surrounding bone changes. RESULT: The nasal polyps were the most common cause of nasal cavity masses(515/567). Group I had a high diagnostic specificity for the nasal polyps (513/515, 99.6%) although inverted papilloma (8/522) and malignant melanoma(1/522) showed similar CT appearances. The representitive nasal mass of Group Ila was the inverted papilloma (15/24, 66.5% of the inverted papilloma). Group III pattern was seen in 3 cases of benign minor salivary gland tumor and 2 cases of pyogenic granuloma. Group IV suggested malignancy and thus was mostly observed in malignant tumors except I case of inverted papilloma and 1 case of granulomatous necrosis. CONCLUSION: The differential diagnosis between nasal polyps and the other nasal cavity masses is possible by characteristic bone changes and their sites of origin revealed on CT. In addition, it is possible to differentiate malignant masses from benign in most cases.

Many unsolved probIems still remain in these in management of trochanteric fracture of hip, especially unstable type of trochanteric fracture. Among many cases of the trochanteric fracture treated during period from Jan. 1963 to July, 1973 at Busan National University Hospital, six patient has severe sequelae such as coxa vara deformity, shortening of the affected limb and ankylosis of the hip joint, which were analyzed clinically and results obtained were as follow. 1. It is the most important factor that the medial and the posterior cortex is good alignment in reduction with internal fixation and maintainance of unstable trochanteric fracture. 2. It is dangerous for the unstable type of trochanteric fracture to be reducted and maintained with only screws or plates. Jewett nail is more effective than the S-P nail and Thornton plate in internal fixation of unstable type of trochanteric franture. 3. The posterior fragments can hardly be found in A-P view but easily in lateral view 4. In cases that had not good alignments between posterior fragments the distaI fragment displaced medially and migration of the naiI, distraction of the pIate, malunion have developed in spite of prolonged immobilization in cast. 5. In one case that the severe coxa vara deformity have been developed. we performed the transverse osteotomy & fixed with Blount-V-blade plate like device. The result was good but the shortening of the limb could not prevent.

Actinomycosis infection can involve most part of the human body including mouth, cervicoface, chest, abdomen and pelvis. Cardiac involvement occurs in less than 2 percent of the infection of actinomyces israelii and pericardial involvement is rare. 34 year male was admitted because of chest pain and general weakness for several months. Echocardiography revealed akinesia of apex suggesting myocardial infarction and large pericardial effusion. Under the impression of pericardial effusion from tuberculosis infection, the patient was started on anti-tuberculosis medicine. Pericardial window operation with pericardial biopsy was performed 7 days later when the patient failed to show a significant improvement. Pericardial biopsy confirmed actinomycosis infection. During admission, the patient had a cerebral infarction with left hemiparesis. The patient was treated with high dose penicillin and improved symptomatically. Echocardiography showed resolution of pericardial effusion.

OBJECTIVES: To report a case of sacral stress fracture that developed after lumbosacral fusion.SUMMARY OF LITERATURE REVIEW: Sacral stress fractures rarely develop after lumbosacral fusion, and osteoporosis, female sex, being over 60 years old, and long segment fusion are known risk factors. MATERIALS AND METHODS: A 66-year-old woman with spondylolisthesis at L5 on S1 underwent posterior lumbar interbody fusion and posterior instrumentation. A sacral stress fracture was found 4 weeks after the first operation, and we performed posterior reduction and posterior instrumentation with S2 alar screws. RESULTS: The patient was free from symptoms and no further displacement was found at 3 months after the last operation. CONCLUSIONS Sacral stress fracture after lumbosacral fusion can be treated with posterior reduction and posterior instrumentation with S2 alar screws.

Purpose: Breastfeeding is the optimal method for feeding a newborn. But insufficient breast milk is the major reason why mothers give up breastfeeding. Herbal galactagogues have been used increasingly to treat postpartum hypogalactia. This study examined the effect of an herbal tea containing Chrysanthemum indicum, as the main ingredient, on milk production in lactating rats. Methods: The herbal tea contained C. indicum (27%), Foeniculum vulgare Mill (21%), Pimpinella anisum (18.2%), Carum carvi (16.1%), Urtica dioica (14.7%), and Gardenia jasminoides (3%). Sixteen lactating Sprague-Dawley (SD) rats were divided randomly into 2 groups, the normal control group (NC; n = 8), and the galactagogue herbal tea group (GHT; n = 8) for 7 days. Lactating rats were administered the decoction of an herbal galactagogue mixture by oral gavage or the same amount of distilled water and milk production was assessed by measuring the pups' weights during the suckling period. The blood concentrations of prolactin, cortisol, oxytocin levels and mammary gland tissues were examined to assess the effects of the galactagogue. Results: Milk production was 9.2% higher in the GHT group given the herbal tea than in the NC group and the difference was statistically significant. The cortisol level in the GHT group was 17.2% higher than the NC group. The herbal tea containing C. indicum increased the size of the alveoli epithelium cells and the mammary lobe. Conclusion The present study revealed the potential of herbal tea containing C. indicum to enhance milk production in postpartum SD rats.

OBJECTIVES: This study was performed to investigate the relationship between job stress and the type of turnover of registered nurses in a university hospital. METHODS: A total of 553 registered nurses who left the hospital between 1994 and 2005 were surveyed, and aninterview record and self-administered questionnaire completed at the time of the turnover were used to assess the relationship. Job stress was categorized into four sub-scales (factor I: insufficient work authority and lack of autonomy, factor II: work overload and time urgency, factor III: interpersonal conflict and communication problems, and factor IV: role strain and ambiguity) using factor analysis. The type of turnover was classified into two categories: voluntary and involuntary. SPSS (version 11.0) was used for the statistical analyses. RESULTS: The direct cause of the turnover was getting a new job, and the nurses in the voluntary turnover group were younger and less experienced than those in the involuntary turnover group. The discriminant analysis findings indicated that the determinant factors affecting the type of turnover were marital status, factor I (insufficient work authority and lack of autonomy), factor II (work overload and time urgency), educational background, and the intention to get a new job. Meanwhile, the voluntary turnover was associated with marital status (single), insufficient work authority and lack of autonomy, high educational background, the intention to get a new job, and low work overload and time urgency. CONCLUSIONS: Job stress played a crucial role in the turnover of the registered nurses, and some job stressors such as insufficient work authority and lack of autonomy, work overload and time urgency were more related to the type of turnover. These results confirm the necessity for a management program or job redesign to eliminate or reduce job stressors which lead to turnover such as insufficient work authority, lack of autonomy, work overload and time urgency. Furthermore, greater opportunities need to be provided for developing their careers. Finally, further research is required to elucidate the specific job stressors affecting the turnover of registered nurses.
