Prenatal chromosome analysis of amniotic cells at 18 weeks of gestation showed a male fetus to carry a large 15p+ derivative chromosome inherited from his mother. Extra genetic material on the short arm of chromosome IS was silver-negative with Ag-NOR (nucleolus organizer regions) stain, but stained darkly with C-banding method like the distal heterochromatic segment of the Y long arm. Fluorescence in situ hybridization (FISH) using two DNA probes (DYZ1 and D15Zl) showed a red fluorescent signal on 15p+ In addition to a green chromosome 15 centromere signal, confirming 15p to be from the distal Yq heterochromatin.

Adenomatoid tumors are well-recognized neoplasms generally to be of mesothelial derivation. We experienced a case of an adenomatoid tumor of the tail of the epididymis in a 56-year-old male. Grossly the tumor was firm and whitish gray, and microscopically it consisted of glandular, cord-like, microcystic structures which were lined by flattened endothelial like to plump cuboidal cells. Immunohistochemical stains whowed positivity for keratin and negativity for facter VIII related antigen and carcinoembryonic antigen. Ultrastructually, there was many long microvilli projecting into the glandular lumina and intracytoplasmic luminal spaces, desmosomes, and prominent cytoplasmic tonofilaments. Those findings strongly support the mesothelial origin of the adenomatoid tumor especially in the glandular type. It also lead us to suggest that the term adenomatoid tumor should be remain in use for light microscopic diagnosis, and that the term adenomatoid mesothelioma should be applied when the mesothelial nature of an adenomatoid tumor is proven by electron microscopy and immunohistochemical stains.

This study was performed to determine dietary and lifestyle factors associated with hypertension in Korean adolescents. Study subjects were 12~19 years (n = 521) adolescents who participated in the 2005 Korean National Health and Nutrition Examination Survey (KNHANES III). Subjects were divided into the hypertensive group (HG, n = 102) and normotensive group (NG, n = 419) by '2007 Korean children and adolescents growth standard' and the relationships between blood pressure and physical measurement, nutrients intakes, eating behaviors and health related factors were analyzed. HG showed significantly higher levels in weight, waist circumference and BMI than NG. The amount of nutrient intakes was not different between NG and HG. Index of nutritional quality (INQ) for phosphate was higher in HG compared with NG. In both male and female HG, INQ for iron was higher but INQ for vitamin B1 was lower than NG. HG revealed higher consumption frequencies of snack, yoghurt, and ice cream compared with NG. In eating and behavioral factors, 'dinner with family', 'eat proper amount', 'keep Korean traditional diet', alcohol drinking, and mean alcohol intake were significantly different between the two groups. By logistic regression method, risk factors for hypertension revealed in this study were gender (male), age (15~19 years), BMI (> or = 85 percentile), and not keeping Korean traditional diet. These results suggest that education program for hypertension prevention in adolescents should include eating habits improvement and lifestyle modification as well as weight control.

It was common to administer glucose to the patients undergoing caesarean section either as a vehicle for oxytocin or to prevent dehydration, ketosis, and hypotension after regional block. The authors investigated thirty cases of mother undergoing caesarean section and their newborn babies to understand the relationship of glucose and electrolytes levels between mother and newborn baby. Five percent dextrose in isctated Ringer's solution was administered as a maintenance fluid. Each patient had a different rate of fluid administration. Blood samples were taken from vein on one of upper extremities of mother and unbillical vein of newborn baby at birth, and femoral vein of newborn baby two hours after birth. In nineteen cases samples from umbilical arteries were taken also. The results were as follows: 1) The levels of potassium in newborn babies were higher than those of mothers, and in newborn the levels at two hours after birth were higher than those at birth. 2) The higher the level of glucose in mother, the higher in newborn baby at birth. 3) The higher the level of glucose in newborn baby at birth, the greater the level of decrease during two hours after birth, and on the contrary the baby who had lower level of glucose showed the tendency to increase two hours after birth. 4) The difference of the level of glucose between umbilical vein and artery in newborn baby was 9.8mg/dl.

Lipoblastoma is a variant of lipoma and lipomatosis occuring almost exclusively during the years of infancy and early childhood. These lesions differ from lipoma and lipomatosis by their cellular immaturity and their close resemblance to the myxoid form of liposarcoma. We experienced one case of lipoblastoma in 21 months old boy who suffered from respiratory tract symptoms such as cough, sputum production, and mild fever. At first he was misdiagnosed pneumonia and treated with antibiotics and conservative management for pneumonia. Later he was rediagnosed as tumor in the left upper lung. For removal of tumor he had operative excision and the biopsies were showed compatible to lipoblastoma. A brief review of related literatures is also presented.

Congenital megacalyces is a congenital renal disease characterized by hypoplasia of the medulla and a non-obstructive dilatation of the calyces. More than 100 cases have been reported in the literature after first described by Puigvert in 1963, but it has been reported only three cases (two cases of adults and one case of child) in the literatures in Korea. The etiology of the congenital megacalyces is unknown. Renal pelvis and ureter are mostly normal in size and there is no urinary obstruction or reflux. Renal medulla of congenital megacalyces is thinner than that of normal kidney but renal cortex retains its normal thickness and function. This is features that help to distinguish megacalyces from obstructive atropy. The calyces are polygonal in shape and the majority of kidney with megacalyces have increased number of calyces. Since congenital megacalyces is a non-progressive lesion, it is important to recognize the clinical entity and avoid unnecessary surgery. We report one case of congenital megacalyces without urinary obstruction or reflux with a brief review of related literatures.

Rudimentary meningoceles represent a developmental anomaly in which meningothelial elements are found in the skin. The majority of rudimentary meningoceles occur on the scalp over the occiput or along cranial suture lines. They are present as a pink papule, nodule or an area of alopecia. Histologically, the lesion consists of scattered foci of meningothelial cells, an anastomosing network of empty spaces with psammoma bodies and collagen bodies, and small vessels, which may be located from the dermis to the subcutis. Immunohistochemically, the meningothelial cells are commonly positive for vimentin and often positive for EMA. We report the cases of two infants who were noted at birth to have scalp hair anomalies. One had a translucent, bald, slightly atrophic patch on the midline of the vertex and the other had a subcutaneous nodule surrounded by long hairs, so called "hair collar sign" on the midline of the occipital area. The latter had an underlying skull defect without a communication with intracranial spaces. Due to the occasional presence of connection to the central nervous system, any midline lesion in an infant, including rudimentary meningocele, deserves careful preoperative evaluation including imaging studies.

Somatostatinoma is rare endocrine tumor that was first described in 1977 by Ganda et al. and Larsson et al. simultaneously. It seems nonfunctioning at clinical level. But it may present with diabetes, diarrhea, cholelithiasis, steatorrhea, indigestion, hypochlorhydria, and anemia. In contrast with pancreatic somatostatinoma, duodenal somatostatinoma, in general, is clinically silent. Duodenal endocrine tumors show similar histologic pattern. Therefore, the definite diagnosis is performed by immunohistochemistry and electron microscopic examination. We have experienced a case of somatostatinoma of duodenum in a 62-year-old male. He has complained generalized pruritus for one year and jaundice for 2 weeks. Grossly, the mass was a intraluminary protruding, polypoid lesion with focal mucosal erosion at immediately distal to Ampulla of Vater. Histologically, it showed tall, cylindrical cells with distinct cell membranes, having granular cytoplasm and small innocent looking nuclei. No mitosis was seen. The tumor cells were arraged in small solid groups and trabeculae, separated by fibrovascular stroma. Immunohistochemically, the tumor cells were strongly positive with somatostatin and negative with several other hormonal and neuroendocrine markers. Ultrastructurally, the cytoplasm contains numerous, homogeneous low electron dense secretory granules, which are essentially similar to those seen in normal delta cells.

This study investigated the health and nutritional characteristics according to household income level and obesity in Koreans aged over 50 years based on the 2005 National Health and Nutrition Examination Survey. Subjects were classified into 3 groups by average household income with reference to the minimum monthly living expenses (MLE): low (n = 319, < 100% MLE), middle (n = 222, < 200% MLE), high (n = 411, > or = 200% MLE) and each group was compared by BMI index. With increasing income level, the prevalence of systolic hypertension and hyperlipidemia was increased. In the low income group, serum total cholesterol, triglycerides, and fasting glucose were higher in the obese compared with the normal. In the middle and high income groups, the prevalence of hyperlipidemia and diastolic hypertension were higher in the obese. Subjects had nutritional imbalance, such as inadequate intake of calcium and potassium. With increasing income level, the percentages of protein and fat to total calorie were increased in addition to the intakes and density of nutrients. The obese in the low income group had higher intakes of energy, protein, phosphorus and higher consumption frequency of cereals and potatoes compared with the normal. It was shown that the obese of the middle and high income groups tended to have lower consumption frequency of Korean cabbage and higher frequency of fruits. The obese of high income group also had binge drinking habit. Therefore, this study suggests that specific approaches based on economic status should be considered in developing nutrition education program for the elderly.
