Adenosis tumor is a ra re tumor of the breast and primarily consists of adenosis. Authors report a case of surgically proved adenosis tumor in a 31-year-old woman. Mammogram showed a Iobulated, well-circumscribed mass with several surrounding radiolucent halos. In the center of the mass several linear radiolucent densities were seen with the appearance of a conglomerated well-circumscribed mass such as fibroadenoma. These linear radiolucent densities were consistent with the fat between the fibrous sclerosis in pathologic specimen. Ultrasonogram showed a well-circumscribed mass with homogeneous low echogenicity, partial posterior enhancement, and bilateral acoustic shadowings.

We report a case of an erythrodermic form of mycosis fungoides in a 68-year-old male, who showed generalized erythroderma with scales for 3 months. Lymphadenopathies in the inguinal and neck areas were present. Histopathological findings showed epidermotropism, perivascular atypical lymphocyte infilteration in the upper dermis, and dermatopathic lymphadenopathy in the inguinal lymph node. T cell markers were positively stained in the immunohistochemical study. These clinicopathological features were consistent with an erythrodermic form of mycosis fungoides(TNM IIl). The patient was treated with PUVA therapy and low dose chemotherapy.

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.

BACKGROUND: This study aimed to investigate bradycardia as an adverse effect after administration of dexmedetomidine during 33degrees C target temperature management. METHODS: A retrospective study was conducted on patients who underwent 33degrees C target temperature management in the emergency department during a 49-month study period. We collected data including age, sex, weight, diagnosis, bradycardia occurrence, target temperature management duration, sedative drug, and several clinical and laboratory results. We conducted logistic regression for an analysis of factors associated with bradycardia. RESULTS: A total of 68 patients were selected. Among them, 39 (57.4%) showed bradycardia, and 56 (82.4%) were treated with dexmedetomidine. The odds ratio for bradycardia in the carbon monoxide poisoning group compared to the cardiac arrest group and in patients with higher body weight were 7.448 (95% confidence interval [CI] 1.834-30.244, p = 0.005) and 1.058 (95% CI 1.002-1.123, p = 0.044), respectively. In the bradycardia with dexmedetomidine group, the infusion rate of dexmedetomidine was 0.41 +/- 0.15 microg/kg/h. Decisions of charged doctor's were 1) slowing infusion rate and 2) stopping infusion or administering atropine for bradycardia. No cases required cardiac pacing or worsened to asystole. CONCLUSIONS: Despite the frequent occurrence of bradycardia after administration of dexmedetomidine during 33degrees C target temperature management, bradycardia was completely recovered after reducing infusion rate or stopping infusion. However, reducing the infusion rate of dexmedetomidine lower than the standard maintenance dose could be necessary to prevent bradycardia from developing in patients with higher body weight or carbon monoxide poisoning during 33degrees C targeted temperature management.

PURPOSE: The purpose of this study was to evaluate the effects of theophylline in preterm infants with apnea on glucose homeostasis and insulin values. METHOD: In this prospective study, level of glucose and insulin were measured from peripheral blood of 8 neonates(1,450+/-114gm, 31+/-2.1week), who were admitted from April 1, 1997 to July 30, 1997 in Neonatal Intensive Care Unit of Wonkwang University Hospital, for apnea of prematurity(> 20 sec with bradycardia and/or cyanosis) were given aminophylline intravenously. Blood samples were collected at pretreatment, posttreatment 2hours, 1-2days, 3-4days, 5-7days and posttreatment 48hours, and compare to those of the 8 control neonates(1,711+/-232gm, 32+/-1.7week). RESULTS: The results were as follows: 1) Plasma glucose values were significantly higher in the treatment group than those of the control group at 1-2days(104.67+/-20.39mg/dL vs 83.43+/-15.86mg/dL) and 3-4days(111.0+/-32.39mg/dL vs 79.25+/-14.03mg/dL)(p<0.05). 2) Plasma glucose values which were increased at 1-2days(104.67+/-20.39mg/dL)and 3-4days(111.0+-32.39mg/dL), were significantly higher than pretreatment values(66.33+/-31.19mg/ dL)(p<0.02), but were not increased to the level of hyperglycemia(> 125mg/dL). 3) The mean posttreatment glucose levels drawn at 48hours after discontinuation of theophylline was significantly decreased to the values of pretreatment values compared to those of the 1-2days and 3-4days(p<0.01). 4) Insulin concentrations were also increased insignificantly when blood glucose were increased in the treatment group compared with control group. CONCLUSION: In conclusion, intravenous administration of theophylline produces hyperglycemia significantly, including an increase in a serum insulin. But, clinically significant hyperglycemia(> 125mg/dL) was not noted. So, plasma glucose may not need to be monitored in preterm apneic infants receiving theophylline. But, further studies are need to elucidate the effect of theophylline considering the serum toxic level of theophylline.

BACKGROUND: An accurate and rapid method for specise identification of coagulase negative staphylococci(CNS) has been increasingly necessary for the clinical significance and planning the management of patients with staphylococcal infections. Recently, it has been reported that there is a highly conserved area on their 60KDa heat shock protein(HSP60) gene sequences between the interspecies of CNS and it can be amplified by a set of universal degenerate primer. This led us our attention to focus on whether the PCR-based RFLP method using Mse / restriction enzyme could be a useful tool for the species identification of CNS. METHODS: In the present study, we performed PCR-based RFLP analysis using a set of degenerate primers covering HSP60 and Mse / restriction enzyme on the reference strains and 25 clinical isolates(10 of S. epidermidis, 10 of S. haemolyticus, 4 of S. lugdunensis and 1 of S. warneri) which were previously identified by the API-STAPH, Vitek GPI card and/or with conventional biochemical test. RESULT: All the seven reference strains revealed that each strain has a distinct electrophoresed band patterns with combination of different number (up to 8) and size of fragments. And these distinct band patterns showed remarkable concordance with the seven reference strains and 25 clinical isolates. CONCLUSION: These result strongly suggest that the PCR-RFLP method using degenerate primers covering the HSP60 gene and Mse / digestion enzyme offer a convenient and accurate tool for species-specific identification of CNS.
