PURPOSE: Computed tomographic(CT), ultrasonographic(US) findings of solid and papillary epithelial neoplasm of the pancreas were correlated with pathologic findings for the better understanding of this disease entity. METHODS AND MATERIALS: A retrospective review of CT and US of 14 cases of solid and papillary epithelial neoplasm of the pancreas was carried out in terms of the margin, internal architecture, caicification and septation, and this was correlated with gross pathologic findings. RESULTS: CT and US findings were well defined round masses consisting of both solid and cystic components. Five cases were cystic, four cases were solid and five cases were mixed. Cystic portion of the tumor represented variable degree of hemorrhagic necrosis. Six cases contained foci of calcification, which were linear, marginal and amorphous. Marginal calcification interfered US examination of the mass in three cases. Internal septurn was demonstrated in four cases on CT, one case on US and three cases on gross specimen. CONCLUSIONS: Our results indicate that calcification and internal septurn were considered as a part of radiologic findings in solid and papillary epithelial neoplasm of the pancreas.

PURPOSE: The cross-protection of 7-valent pneumococcal conjugate vaccine (PCV7) against vaccine-related serotypes has been controversial. We investigated the serological properties of cross-protective antibodies against vaccine-related serotypes 6A, 6C, and 19A induced in young children aged 12-23 months after booster immunization of PCV7. METHODS: IgG and IgM antibody concentrations and opsonic index (OI) against vaccine serotypes 6B and 19F and vaccine-related serotypes 6A, 6C, and 19A were measured by ELISA and opsonophagocytic killing assay (OPA) in 4 selected immunesera. The serological properties and antigenic specificity of protective antibodies were determined by IgM depletion of immunesera, OPA, and competitive OPA against serogroup 6 and 19 pneumococci. RESULTS: Compared to pre-IgM depleted immunesera, OI of IgM-depleted immunesera against 6B and 19F decreased and OI against 6A, 6C, and 19A decreased, too. In competition OPA, free 6B and 19F polysaccharide completely inhibited the immune protection against vaccine-related serotypes 6A, 6C, and 19A as well as vaccine types 6B and 19F. CONCLUSIONS: The booster immunization of PCV7 certainly induced cross-protective antibodies against vaccine-related serotypes 6A, 6C, and 19A with both IgG and IgM isotypes. Furthermore, IgM antibodies are more highly contributed to opsonophagocytic activity against vaccine-related serotypes as well as most of vaccine types than do IgG antibodies. Further studies are needed for the more immunized sera in the children as well as adults.

A clinical and histopathological study was performed on ninety-four patients with nephrotic syndrome (91 idiopathic and 3 secondary) who were admitted to Department of Internal Medicine, Yeungnam University Hospital during the period of nine years, from January 1985 to May 1994. The results were as following. 1. the ratio of male to female was 1.76:1. In young age group, minimal change was the most predominant type. In old age group, membranous glomerulonephritis and focal glomerulosclerosis were predominant types. 2.- The primary nephrotic syndromes were 96.8% and secondary nephrotic syndromes were 3.2%. Histopathologic findings of 94 renal biopsy tissue were classified into minimal change (43.6%) mesangial proliferative glomerulonephritis (29.8%), membranous glomerulonephritis (12.8%), Typel membranous proliferative glomerulonephritis (4.3%), focal glomerulosclerosis (3.2%) .and others (6.4%). 3. The response of eighty-six patients treated with steroid showed complete remission in 51.2%, partial remission in 20.9%, steroid dependent in 2.3%, and no effect in 25.6% of cases respectively. The response to steroid therapy was most effective in the patients with minimal change lesion. 4. In the patient with membranous proliferative glomerulonephlitis, long-term angiotensin converting enzyme inhibitor treatment showed less deterioration of renal function.

PURPOSE: The purpose of this study is to illustrate MR patterns of bone marrow of calvarium and vertebral body in normal subjects according the age distribution and to understand the course of the fatty replacement from red marrow. METHODS AND MATERIAL: We retrospectively evaluated MR examinations of the calvaria(n=71), cervical spine(n=71), thoracic spine(n=65), Imbar spine(n =68) in subjects without bone marrow abnormality whose age ranged 3 weeks to 74 years. Three distinctive patterns were categorized on Tl-weighted images of the skull. In pattern 1, uniformly low signal intensity with or without very small areas of high intensity in frontal and occipital bones is noted. In pattern 2, frontal and occipital bones have uniformly high signal intensity, and patchy area of high intensity appears in parietal bone. In pattern 3, the entire skull has uniformly high signal intensity. In the spine, four patterns were categorized on Tl-weighted MR images. In pattern 1, the vertebral body has uniformly low signal intensity except for linear areas of high intensity superior and inferior to basivertebral vein. In pattern 2, bandlike and triangular areas of high signal intensity are found in the periphery. Pattern 3 and 4 have diffusely distributed areas of high signal intensity; pattern 3 consist of numerous indistinct dots measuring a few millimeter or less, and pattern 4 consist of fairly well marginated areas ranging in size from 5 to 1.5cm. RESULT:In the calvaria, 73% of pattern 1 were younger than 20 years, pattern 2 were evenly distributed, and 86% of pattern 3 were older than 40 years. In the spine, 87% of pattern 1 were younger than 40 years, 72% of pattern 3 were in 40 to 50 years, and 87% of pattern 4 were older than 50 years. Pattern 2 were evenly distributed in the cervical and thoracic spine, but in the thoracic spine 62% were younger than 30 years. CONCLUSION:It is concluded that younger age group shows mainly pattern 1, whereas elderly group has pattern 3 or 4 in the calvarial and vertebral body marrow. This suggests that conversion to fatty marrow begin locally and progress diffusely with age.

We report the case of a 20-year-old female with lymphoma of the breast. Mammography showed an asymmetric pattern of confluent densities without any discrete mass. Sonography revealed diffuse heterogenous echoic mass intermingled with low-and medium level echoes. We present the clinical, radiographic and histologic features of primary breast lymphoma with a brief review of the literatures.

BACKGROUND: Overnight transfusions have been associated with higher transfusion risk than transfusions during the day. The aim of the study was to evaluate the transfusion status at our hospital and to help provide plans for overnight transfusions. METHODS: All blood products, including red blood cell products (RBC), fresh frozen plasmas (FFP), and all platelet products (PLT) issued between January 2013 and December 2014 were included. Night1 (5 pm∼8 am) and Night2 (8 pm∼8 am) were defined as overnight, and all issued bloods (IB) were analyzed in accordance with the issued time, ordered medical departments, and the reason of transfusion. RESULTS: The total unit number of IB at Night1 (Night2) was 53,483 (38,224), and it consisted of 44.4% (31.7%) total IB; 53.2% (39.6%) FFP; 46.8% (33.4%) RBC; and 39.3% (27.6%) PLT. The IB ordered from the departments of trauma & acute care surgery and emergency medicine consisted of 40% IB. The 80.9% RBC, 53.1% FFP and 70.2% PLT could be considered as appropriate for overnight transfusion. CONCLUSION: Due to the characteristics of our hospital with many trauma patients, the percentage of IB during an overnight period in our hospital was higher than those in other countries, and the rate of appropriate reason for RBC transfusion was also higher. However, as inappropriate overnight transfusions may have been still performed, education for medical staffs and appropriate policies for overnight transfusion could be helpful in reducing inappropriate transfusion.
