Although heterotopia of pancreatic tissue is a developmental anomaly found in approximately 2% of all autopsies, pancreatic tissue within the thorax and mediastinum is uncommon. In most of these instances, the pancreatic tissue is a component of gastroenteric duplication cysts, intralobar pulmonary sequestrations or teratomas. We describe an anterior mediastinal cyst consisting entirely of pancreatic tissue. A previously healthy 27-year-old woman was admitted due to chest pain during deep inspiration. The computed tomographic scan of the thorax showed a large cyst occupying the right anterior mediastinum. The excised multilocular cystic lesion measured 12 cm in maximum diameter and contained a brown, turbid fluid. The wall was fibrotic and showed a haphazard mixture of ducts and exocrine acini without islets. The histogenesis of this lesion is unclear.

PURPOSE: In this study, emotional reaction of psychiatric nurses and resident physicians toward suicidal behavior of psychiatric inpatients was examined. METHODS: Subjects were 396 working in general hospitals or mental hospitals. Demographic factors, exposure to suicidal behaviors, mood states, and impact of event scores were collected between April and July 2008. Mood state was measured with Korean Edition of Profile of Mood States (K-POMS). Impact of event was measured with Impact of Event Scale-revised (IES-R). RESULTS: Of the respondents, 90.9% experienced at least one inpatient suicidal behavior. Emotional responses of respondents after their patients' suicidal behavior were shock, anxiety, self-doubt and disbelief. Mood states were negative for those who had worked over 10 years, had experienced colleagues quitting and were significantly different according to patient's diagnosis, period of maintaining emotions, and level of stress. Impact of event was high among those who were nurses, had worked in mental hospitals, had worked over 10 years, had experienced colleagues quitting and were significantly differenced according to job status, patient's diagnosis, period of maintaining emotion, and level of stress. CONCLUSION: This study confirms that suicidal behaviors of inpatients are commonly encountered and significantly stressful events for psychiatric nurses and physicians.

To obtain a useful method for the identification of mycobacteria in tissue section, we evaluated 118 cases of tuberculosis: 48 pulm onary, 14 lymph nodal and 56 synovial tuberculosis. Seventy nine of these cases underwent the culture study. Sections stained with anti-Mycobacterium bovis were compared with the results of the Zieh1-Neelsen stain and culture. The immunohistochemical stain for Mycobacterium bovis in al examined cases was not any more sensitive than the Zieh1-Neelsen stain(p>0.05). Neverthless, the immunohistochemical stain was a useful method for the localization of mycobacteria because of the striking contrast between its background and the wider dimension of a positive area. Immunoreactive areas demonstrated a few intact mycobacteria showing a positive reaction in the Zieh1-Neelsen stain. In conclusion, double staining method using the immunohischemical stain for Mycobacterium bovis and the Zieh1-Neelsen stain is an efficient technique in oder to confirm the diagnosis of tuberculosis.

All ceramic restorations have had a more limited life expectancy than metal ceramic crowns because of their lower strength. The relatively lower strength has limited the use of all-ceramic crowns to the areas where occlusal loads are lower. Therefore many researches have been done to increase the strength of all-ceramic crowns. IPS Empress 2 is a new type of lithium disilicate glass-ceramic with enhanced physical characteristics which has been in use clinically since 1998. Previous researches reported that the flexural strength of all-ceramic material was greater than 300MPa, and all-ceramic crowns can be used in staining or layering technique. The objective of this study was to investigate the influence of the thickness of IPS Empress 2 ceramic on fracture strength. Both staining technique and layering technique was investigated. Vita VMK was used as control. For all three groups, five specimens each of 0.8mm, 1.0mm, 1.4mm, 1.8mm, and 2.2mm thickness (a total of 75 specimens) were prepared. Control group: Vita VMK Porcelain specimens were prepared with dentine ceramic and liquid glazing was done. Group I: IPS Empress 2 were prepared with staining technique and stained twice and glazed once. Group II : IPS Empress 2 were prepared with layering technique and glazed after wash firing. The thickness and diameter of the specimen were measured and controlled after specimen preparation. Biaxial Flexure Test (ASTM Standard F394-78) was adopted as this test method produces results least affected by the edge condition of the specimens. Fracture strength was measured with Instron Universal Testing Machine. Conclusions are as follow : 1. The fracture strength was increase in order of control group, test group I, test group II. 2. Fracture strength of the group I(Empress 2 Staining) was 65.54 N in 0.8mm, 155.2 N in 1.0mm, 233.5 N in 1.44mm, 434.5 N in 1.8mm, and 600.1 N in 2.2mm. 3. Fracture strength of the group II (Empress 2 Layering) was 190.0 N in 0.8mm, 283.5 N in 1.0mm, 437.2 N in 1.4mm, 732.0 N in 1.8mm, and 1115.0 N in 2.2mm. 4. No statistical difference was found in flexural strengths according to thickness in a specified group(p>0.05).

Recently, cell cycle regulators have been suggested as new prognostic factors of the lung cancer. In this study, we evaluated the expression of cyclin D1, p21, and p53 using the X2-test, with regard to the stage of the patients, histologic type, and histologic differentiation in the 135 cases of non-small cell lung carcinomas (NSCLC). To evaluate the confounding effects among cyclin D1, p21, and p53 on X2-test analysis, we used the Mantel-Haenzel test. The NSCLC in this study included 82 cases of squamous cell carcinoma and 53 cases of adenocarcinoma. Each nuclear staining of cyclin D1, p21, and p53 was observed in 65 cases (48.1%), in 54 cases (40.0%), and in 81 cases (60.0%) of NSCLCs, respectively. Only p53 expression was significantly associated with the stage (stage I, II, IIIa) (p<0.05) and squamous cell carcinoma (p<0.05). On the other hand, cyclin D1 expression was significantly associated with the histologic differentiation. The confounding effects among cyclin D1, p21, and p53 revealed that only p21 expression changed the relationship between p53 and stage. In this regard, further study is needed.

We reviewed 7 cases of congenital mesoblastic nephroma (4 cases of classical mesoblastic nephroma (CMN) and 3 cases of atypical mesoblastic nephroma (AMN)) using immuno-histochemical and flow cytometric study. Results are as follows. 1) The mean tumor size was 5 (3 to 7cm)cm in CMN and 9 (7 to 10cm)cm in AMN. The AMN revealed hemorrhage and necrosis in two Of three cases. A case of AMN showed cystic change without hemorrhage and necrosis. Mitotic count ranged in 0~4/10HPF in CMN and 20-35/10HPF in AMN. 2) Immunohistochemistry for vimentin was all positive. Actin, desmin were weakly positive in CMN, but negative in AMN. The findings were consistent with myofibroblastic differentiation in CMN and AMN was considered to be the less differentiated form of CMN. 3) Flow cytometiic analysis showed diploidy in two of two CMNs and two of three AMNs. Only one AMN showed aneuploidy with DNA index of 1.41. %SG2M were 8.1 and 15.9 (mean 12.0) in CMN and 16.9, 32.9 and 19.3 (mean 22.9) in AMN, respectively. We concluded that AMN should be distinguished from CMN, clinicopathologically.

Paroxysmal nocturnal hemoglobinuria(PNH) is a rare, acquired disease involving multiple hematopoietic lines. Characteristics of PNH are intrinsic hemolytic anemia, iron deficiency anemia and venous thrombosis. report a case of PNH with characterostoc MR and CT findings. The signal intensity of renal cortex was lower than that of medulla on both T1- and T2- weighted MR imaging. On T2 weighted MR images, the liver showed very low signal intensity but the signal intensity of the spleen was normal. On precontrast CT the attenuation of renal cortex was higher than that of renal medulla and the attenuation of liver was higher than that of the spleen. These findings of MR imaging and CT were the result from the deposition of hemosiderin in the cells of proximal convoluted tubules and transfusional hemosiderosis of liver.

With rapid advancement in techniques of correcting multiple facial anomalies, surgical planning has become more sophisticated, and knowledge of the exact relationship between various areas of the head and face is now indispensible. The importance of capturing the face in proportions has been emphasized by many surgeons. The neoclassical canons are known to modern plastic surgeons, but their usage in surgical planning has been limited to the role of working guides. They are useful, however, in serving as standards. The authors measured 800 normal young Korean females, ranged from 19 to 26 in age, and 21 beauty contestants in Korea, ranged from 20 to 27 in age. Seven vertical and seven horizontal linear measurements were taken from each subject by one examiner. These measurements of normal face and attractive face are compared with each other, and followed by comparison with neoclassical canons. Attractive face of Korean female comprises shorter lower face, especially from stomion to menton, narrower bigonial distance, and longer midface than normal face. It also has wide palpebral fissure and narrow intercanthal distance. Korean female face comprises shorter and narrower lower face than neoclassical canons. We think that it is valuable to take into consideration of this modern concept of beauty when making a preoperative plan for facial plastic surgery.
