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.

PURPOSE: In children on anticancer chemotherapy, bloodstream infections (BSIs) are a major cause of morbidity and mortality. We investigated febrile episodes and bloodstream infections in pediatric cancer patients to guide proper selection of empiric antibiotics for febrile pediatric hemato-oncologic patients. METHODS: All febrile episodes treated in the division of hematology-oncology, the department of pediatrics, Hanyang University Hospital, between July 2005 and June 2008 were reviewed. Episodes with and without bloodstream infections were compared. RESULTS: Forty cases (18.9%, 25 patients) of BSI occurred in 212 febrile episodes (63 patients). Thirty-seven cases (23.6%, 22 patients) of BSI occurred in 157 febrile episodes with neutropenia (54 patients). Microorganisms identified in BSI corresponded to 23 gram-positive bacteria (51.2%), 20 gram-negative bacteria (44.5%), and 2 fungi (4.4%). Rates of BSI between those who had received umbilical cord blood transplantation and those who had received transplantation from other source were significantly different (55.0% vs. 7.7%, P=0.001). No differences in mortality rate were observed among organisms in BSI patients. For febrile episodes the rate of BSI was higher among those with Chemoport than those with Hickman catheter (P=0.029) and gram-positive pathogens were more likely to be associated with Chemoport (P=0.001). CONCLUSION: The study showed the rate of BSI, distribution of pathogens with regard to neutropenia, transplantation, central venous catheters, and antimicrobial susceptibility of pathogens in order to help guide in the choice of optimal empiric antibiotics in pediatric febrile neutropenic hemato-oncologic patients.

Lovastatin(Mevacor) belongs to a new generation of potent drugs for the treatment of hypercho- lesterolemia. It acts by competitive inhibition of 3-hydroxyl-3-methylglutaryl coenzyme A(HMG-CoA) reductase, diminishing in that way the cholesterol synthesis in the liver. HMG-CoA reductase inhibitors also affect cutaneous lipid content. This can induce cutaneous side effects such as eczernatous rashes or xerotic, ichthyosiform lesions due to abnormality in the barrier function in some patients. We report a 54-year-old male patient who developed ichthyosiform skin lesions under treatment with lovastatin(Mevacor) for hypercholesterolemia.

Clinical observations were made on 338 low birth weight infants, who were delivered at Pusan Wallace Memorial Baptist Hospital, during the 3 year periods from 1989 to 1991. The results were as follows; The incidence of LBWI was 5.6% and sex ratio was 1:1.09. Among them AGA was 62.7%. 2) Of all infants, 47.3% were in the birth weight range of 2251-2500 gm and 25.1% were in the gestational age group of 37-38 week. 3) LBWI were most prevalent among mothers under 20 years old and over 41 years old. 4) The Incidence of LBWI was higher in multiparity than primiparity and in multiple pregnancy than single pregnancy. 5) Vaginal delivery was 63.9% and c-section delivery was 36.1%. 6) The order or frequency of the etiology of LBWI was multiple pregnancy, premature rupture of membrane and toxemia. 7) The mortality rate of LBWI was 12.7% and mortality rate by weight-gestational age was lower in AGA group than SGA and LGA group. 8) A Higher mortality rate was noted in the group of lower birth weight infant, and in the group of more shortened gestational age. 9) 48.8% of death occured within ist day of birth. The common causes of death were respiratory distress syndrome, asphyxia, and apnea.

The VATER syndrome is a group of congenital anomalies with a nonrandom tendency for concurrence. Defects include vertebral, anorectal malformation, tracheoesophageal fisutla with esophageal atresia, radial-limb, vascular, and renal abnormalities. The critical period of organogenesis is at or before the sixth or seventh week of gestation. We experienced one case of VATER syndrome in a 1 day old male neonate having vertebral anomalies, esophageal atresia with tracheoesophageal fistula to the distal esophageal segment, imperforated anus, left renal dysplasia with hydronephrosis of the right kidney and both hydroureter, patent ductus arteriosus. We report a case of VATER syndrome with brief review of related literature.

Consumption of liquid digestive medicine has continually grown in recent years. This present study was designed to evaluate the capability of liquid digestive medicine to erode dental enamel, relating the pH and titratable acidity of liquid digestive medicine. Three commercially available liquid digestive medicines were chosen these were Gashwalmyeungsu, Saengrokchun and Wicheongsu. The liquid digestive medicines were evaluated in respect to pH, titratable acidity and concentrations of calcium and phosphate, respectively. This measure was carried out three times for each digestive medicine and was recorded the data as mean (standard deviation). Bovine enamel specimens measured microhardness at base line and then were randomly assigned to 4 groups of 10 each. The specimens were immersed into each liquid digestive medicine for 1, 3, 5, 10, 15, and 30 minutes and then evaluated each time by VHN. All digestive medicines had a pH of less than 3.7. Wicheongsu had the lowest pH 2.93 and Gashwalmyeungsu had highest pH 3.63. In pH 5.5, titratable acidity of Wicheongsu was 1.27 ml. Gashwalmyeungsu was 0.63 ml. Saengrokchun was 0.60 ml. All liquid digestive medicines showed low concentration of calcium and phosphate. The microhardness of specimens after immersion into liquid digestive medicines was continuously reduced in all digestive medicines. After 30-minute treatment in liquid digestive medicines, Wicheongsu containing low pH and high tiratable acidity was shown to be lowest microhardness value (207.80µ15.52). The three liquid digestive medicines caused surface softening of enamel erosion. We conclude that drinks, commonly consumed by functional dyspepsia patient can cause erosion of enamel.
