Ground-glass opacity is a frequent but nonspecific finding seen on high-resolution CT scans of lung parenchyma. Histologically, this appearance is observed when thickening of the alveolar wall and septal interstitium is minimal or the alveolar lumen is partially filled with fluid, macrophage, neutrophils, or amorphous material. It has been shown that ground-glass opacity may be caused not only by an active inflammatory process but also by fibrotic processes. When a focal area of ground-glass opacity persists or increases in size, the possibility of neoplasm-bronchioloalveolar carcinoma or adenoma, or lymphoma, for example- should be considered. Diffuse nonsegmental ground-glass opacity in both lung fields was incidentally found on follow up abdominal CT in a stomach cancer patient and signet-ring cell-type metastatic lung cancer was confirmed by transbronchial lung biopsy. We report a case of diffuse ground-glass opacity seen in metastatic lung cancer from adenocarcinoma of the stomach.

PURPOSE: Intussusception is one of the most common causes of an acute abdomen in infancy. The majority of pediatric cases of intussusception are of the ileocolic type and usually idiopathic. Small bowel intussusception is rarely diagnosed in children, and few cases have been reported. The purpose of this study was to determine the clinical features and causes of small bowel intussusception in children. METHODS: We retrospectively reviewed the clinical and radiologic findings of 21 children with small bowel intussusception who were admitted to Seoul National University Children's Hospital between March 2005 and January 2010. RESULTS: The clinical presentation of small bowel intussusception included abdominal pain or irritability (85%), vomiting (23%), fever (14%), bloody stools (14%), and abdominal masses (4%). Six patients required surgical management. Ultrasonography showed that the mean diameter of the lesions and mean thickness of the outer rims were 1.6+/-0.7 and 1.7+/-1.8 mm, respectively. Eleven lesions were located in the left abdominal or paraumbilical regions. Children who underwent surgical management were older than children with transient small bowel intussusception (mean age, 51 vs. 109 months). The mean diameter of the lesions and mean thickness of the outer rims were greater in the surgically-managed group. The location of intussusception was not significantly different between the two groups. CONCLUSION: Small bowel intussusception was spontaneously reduced in a large number of pediatric patients. However, sonographic demonstration of larger size, older age, and pathologic lead point warrant surgical intervention.

PURPOSE: In this study a cognitive enhancement group training program of 10 sessions was provided for community-dwelling elders and the effects on cognitive function, depression and quality of life were tested. METHODS: A quasi-experimental study using a nonequivalent control group, pre-post design was used. The participants were 87 elders whose cognitive function was within the normal range. Of these elders, 45 were assigned to the experimental group and 42 to the control group. The intervention was conducted once a week for 10 weeks. Chi-square test, t-test, paired t-test, Wilcoxon rank sum test and Wilcoxon signed rank test were used to analyze the data. RESULTS: After the program, the cognitive function (t=-2.85, p=.006), depression (z=2.82, p=.005) and quality of life (t=2.79, p=.007) of the experimental group was significantly better than those of the control group. Especially, immediate recall (z=2.45, p=.014) and concentration (z=2.58, p=.010) in the subcategory of cognitive function were significantly better than that of the control group. CONCLUSION: The findings indicate that the cognitive enhancement group training program was effective in enhancing the cognitive function, depression and quality of life for elders and could therefore be considered as a positive program for emotional and cognitive support for community-dwelling elders.

BACKGROUND/AIMS: Hepatic fibrosis in rat induced by thioacet amide shares similar morphological and biochemical characteristics with human liver cirrhosis. Thioacetamide (T AA) initially induces accumulation of collagen in Disse space and eventually leads to macro- and micronodular cirrhos is. Ito cell was believed to play a main role in hepatic fibrosis. And it s activity was known to be regulated by the expression of various genes. But little has been discovered about the upstream signal trans duction pathway of these genes in hepatic fibrosis. The expression of genesrelated to Ito cell activity was regulated by many transcription factors , the activity of which was regulated by protein kinase C( PKC) is oforms. So it is s upposed that PKC could be as s ociated with fibrosis in liver. METHODS: We investigated the correlation of PKC is oforms and It ocell activity in the course of hepatic fibrosis using TAA induced rat liver cirrhosis model. We used six week- old male rats , and administered 0.03% TAA in drinking water. The animals were sacrificed at 9, 20, and 30 weeks after TAA administration. The degree of hepatic fibrosis was evaluated by measuring the total amount of collagen.-SMA immunohist ochemical st aining of liver tissue was done to determine the Ito cell activity. The expression pattern of PKC isoforms was investigated by West ern blotting. RESULTS: In TAA- treated group, collagen cont ent and Ito cell activity did not increase until 30 weeks and 20 weeks of treatment , respectively, while in control group collagen cont ent and Ito cell activity were not detected. Collagen content showed linear correlation with Ito cell activity. This implied that the proliferation of activated Ito cells was prior to the increase of collagen content. In view of expression pattern of PKC is oforms, PKC alpha showed no difference in TAA- treated group and control group. In TAA-treated group, PKCbeta1 exhibited increased level of expression in both particulate and cytosolic forms at 9 weeks, while PKCdelta and PKC epsilon showed striking shift to particulated form. After 20 weeks, all of the PKC beta1, delta, and epsilon degenerated and showed remarkably decreased level of expression. This suggested PKC alpha had no relation to hepatic fibrosis,while PKC beta1, delta, and epsilon, showing activity at 9 weeks, were related to fibrosis og liver. In response to fibrogenic factors, molecules engaged in intracellular signal transduction pathway like PKC beta1, delta, and epsilon, began to change prior to the increase of Ito cell activity, morphologic changes and alterations of collagen content. CONCLUSION: Our results strongly suggest that the activity of PKC isoforms play an important role in early step of hepatic fibrosis, while accompanying Ito cell activity do in later step.

BACKGROUND/AIMS: Liver cirrhosis is an end-stage liver disease. Ito cell is known to have central role in fibrogenes is of liver cirrhosis. But collagen content and Ito cell activity in liver cirr hosis have received little attention. So Ito cell activity and hepatocyte proliferation activity according to collagen content was investigated. WAF-1 and c- met were studied to evaluate the effect of cell cycle. METHODS: We analyzed 56 cases of liver cirrhosis ( viral:41, biliary:11, alcoholic:2, Wilson' s disease:2). Collagen content was measured by spectrophot ometry. Ito cell activity and prolifer ation index was measured by-SMA and Ki- 67 immunohistochemistry. RESULTS: In viral cirrhosis, high collagen group showed increased Ito cell activity compared to low collagen group. There was no difference in hepatocyte prolifer ation activity bet ween high and low collagen group in viral cirrhosis. In biliary cirrhos is, high collagen group showed increased Ito cell activity in septal zones compared to low collagen group. WAF- 1and c- met were negative in most of cases. CONCLUSION: Collagen content of liver cirrhosis is closely related to increment of activated Ito cells . Ito cell activity was prominent in septal zones than in parenchymal areas of viral cirrhosis and that was only significant in septal zones of biliary cirrhosis. There is no correlation bet ween collagen content and hepatocyte proliferation activity.

OBJECTIVE: Ovarian failure is often common complication by the conditioning protocol used for bone marrow transplantation (BMT). To determine the frequency of recovery of ovarian function after allo-BMT and the major factor that predict recovery, we monitored ovarian function in 24 premenopausal women METHOD: Twenty-four women met the inclusion criteria, which were (1) moderate to severe aplastic anemia before BMT, (2) disease-free at least 18 month after transplantation, (3) age younger than 40 years and more than 3 years after menarche at transplantation and (4) regular menstrual periods before transplantation. Recovery of ovarian function was determined by regular menses without menopausal symptom and sign. we divided conditioning regimen to two groups, Group I : cytoxan alone(n=17), Group II : cytoxan plus total body irradiation (TBI)(n=7). RESULTS: All women became amenorrhea after BMT and the clinical characteristics were not significant between two groups. 17 patients who received only cytoxan all recovered ovarian function between 1 to 14 months(median : 7.28) after BMT. The median age at BMT of women with regained ovarian function was 26 years (range, 21 to 33) versus 30 (range, 21 to 37) for those who did not. The age at transplantation was not significant between two groups in our study and the most predictive independent factor in ovarian recovery is the presence of total body irradiation. None of women who received TBI regained ovarian function during 19-49 month follow up. CONCLUSION: Gonadal insufficiency due to pre-BMT conditioning is more severe in radiation based regimen than cytoxan alone. therefore, we recommend early hormone replacement therapy in radiation treated women to prevent the complication of premature menopause.

Benign or malignant tumors that arise in a benign cystic teratoma are rare. Malignant transformation in mature cystic teratoma of ovary is reported to occur in 1~3%. Several types of malignancy can occur from any of three germ-cell layers, but the most common malignancy is a squamous cell carcinoma derived from ectoderm. We experienced a papillary carcinoma arising in a struma ovarii of the complex teratoma. 74-year-old female presented with an abdominal discomfort. A pelvic ultrasonograph and computed tomography detected a 7 x 6 cm-sized and well-circumscribed cystic mass at the anterior to the uterus. The inner part of the mass was filled with cystic fluid showing low-density, however, solid portion including fat and soft tissue accompanied by calcification was identified in more than half of the entire tumor volume. The patient underwent a bilateral salpingo-oophorectomy. On histopathologic examination, the lesion was consistent with papillary carcinoma with squamoid features arising in a struma ovarii of the mature cystic teratoma. We herein report a case of the very rare papillary carcinoma arising in a struma ovarii of the complex teratoma and review the available literature.
