BACKGROUND: Extended-spectrum beta-lactamase-producing (ESBL) Klebsiella pneumoniae is an important cause of nosocomial infections in neonatal intensive care units (NICUs). This study aimed to reduce ESBL-producing K. pneumoniae in the NICU by using infection control measures. METHODS: We performed prospective surveillance cultures, monitoring, and education for infection control in the NICU between May and August 2011. Specimens were collected from all infants and the environment including stethoscopes, thermometers, ventilators, incubators, etc. The anterior nares and hands of healthcare workers were also screened. We inspected infection control practices and provided feedback. The level of infection control awareness was measured using a questionnaire. RESULTS: The level of awareness and performance of hand washing increased significantly after intervention (both P<0.001). The environmental management of healthcare providers also improved significantly (P=0.001). The yield of ESBL-producing K. pneumoniae from clinical specimens decreased gradually throughout the study period (30.4% in May to 12.6% in August). Central catheter-related K. pneumoniae bacteremia decreased from 1.3/1000 to 0/1000 catheter-days. CONCLUSION: Infection control measures including education, monitoring, and surveillance can lower the incidence of ESBL-producing K. pneumoniae in the NICU.

BACKGROUND: Core hypothermia after induction of anesthesia results from an core-to-peripheral redistribution of body heat and a loss of body heat to environment. The purpose of this study is finding body temperatures during operation by either general of epidural anesthesia and evaluates content of total body heat. METHODS: We measured tympanic membrane temperature, 4 point skin temperature (mid calf, mid thigh, upper extremity, nipple). And we calculate mean skin temperature, mean body temperature, total body heat content changes based on tympanic membrane temperature and 4 point skin temperature. RESULTS: Tympanic membrane temperature of the first group decreased significantly after 10 minutes of induction (p<0.005), the second group decreased after 45 minutes of induction. Although upper extremity temperature has continuously increased as time passed, there was no significant difference in both group. Lower extremity temperature has significantly increased after 30 minutes of induction in the first group, and the second group has significantly increased after 10 minutes of induction (p<0.05). Mean skin temperature hasdecreasd temperaturily in both group after 10 minutes of induction and increased as time passed. Mean body temperature of the first group has significantly decreased after 10 minutes of induction (p<0.05) and second group has no significant changes. Total body heat content has continuously decreased after induction with no significance. CONCLUSIONS: General anesthesia reveals more significant decrease than epidural anesthesia. Both groups show significant decrease of body temperature after induction. We think that we need to close attention to temperature changes after induction for preventing possible side effects due to core hypothermia.

The purpose of this study is to demonstrate a new postoperative analgesic which minimize the physiological changes of patients. Recently, it has become popular to administer opioids to epidural space rather than intravenously or by intramuscular administration. However, the side effects of opioids have limited the usefulness of this procedure. We tried to find out a way of providing postoperative analgesia while minimizing the side effects of opioids. This study has tested the effects of administering a mixture of small doses of morphine, fentanyl and bupivacaine and epidural morphine alone. The data of this study has taken from 20 paturients who have scheduled for cesarean section. We have classified into two groups which consist of 10 paturients each. We have administered epidural morphine alone to the first group and a small doses of morphine-fentanyl-bupivacaine mixture to second group. We have evaluated analgesic effects by comparing both groups' pain scores of the operative day and of the first postoperative day and evaluated such side effects as the degree of itching, nausea, vomiting, dizziness and respiratory depression by asking to paturients. This study has found the followings: 1) Pain scores of the first group in the operative day and the first postoperative day are 1.2+/-0.4 and 0.4+/-0.5. The second group's pain scores are 0.2+/-0.4 and 0, and the second group's pain scores have significantly reduced (p<0.05). 2) Frequencies of such side effects as itching, nausea and vomiting are higher in the first group (8) than in the second group(4). In conclusion, small doses of morphine-fentanyl-bupivacaine mixture has demonstrated a more effective postoperative analgesia with minimum side effects in pain controlling after cesarean section than epidural morphine alone.

BACKGROUND: Pelviscopic techniques have rapidly increased in therapeutic procedures as well as diagnostic procedures because of the many benefits associated with much smaller incisions than traditional open techniques. But the deliberate pneumoperitoneum with carbon dioxide during pelviscopic surgery may cause some problems-hypercarbia, pneumomentum, subcutaneous or mediastinal emphysema, pneumothorax, hypoxemia, hypotension, cardiovascular collapse and cardiac dysrhythmia. METHOD: We observed the changes of blood pressure (systolic, mean, diastolic), pulse rate, PaCO2, PaO2, peak inspiratory airway pressure and expired tidal volume at 10 minute after induction of general anesthesia (control value), 30 minutes and 60 minutes after insufflation of CO2 and Trendelenburg position. RESULTS: The blood pressure, PaCO2 and peak inspiratory airway pressure were increased significantly than control values (p<0.05). The changes of pulse rate and expired tidal volume were not statistically significant in comparison to control values. The PaO2 was decreased significantly (p<0.05). CONCLUSION: To minimize the risk of CO2 retension and unstability of cardiovascular system during pelviscopy under the Trendelenburg position, we must monitor the vital signs and the arterial blood gas status continuously and carefully.

PURPOSE: Abdominal CT scans in patients with intraperitoneal fluid were retrospectively studied to identify characteristic features useful for differential diagnosis of various causes. MATERIALS AND METHODS: One hundred and seventy patients with intraperitoneal fluid collection were classified as categories of hepatic disease, carcinomatosis, and infectious disease. We analyzed sites of fluid collection, the presence of peritoneal thickening, omental and mesenteric fat infiltration, and lymph node enlargment. RESULTS: Intraperitoneal fluid was present in subhepatic space, subphrenic space, paracolic gutter, mesentery, and fossa of the gallbladder in decreasing order of frequency. Fluid in the gallbladder fossa was the most frequent in hepatic diseases. The fluid collection in subhepatic and subphrenic space was less frequent in infectious diseases. Peritoneal thickening was noted in infectious diseases, and carcinomatosis. Omental fat infiltration and enlarged lymph nodes were the most frequent in carcinomatosis (58% and 44%, respectively), whereas, mesenteric fat infiltration and enlarged lymph nodes were the most common in infectious diseases (61%, and 26%, respectively). CONCLUSION: The location of peritoneal fluid collection showed some lesion specific characteristics, and CT features of fat infiltration and enlarged lymph nodes of peritoneum, omentum, and mesentery were helpful for differential diagnosis between carcinomatosis and infectious diseases.

The polyglandular autoimmune(PGA) syndrome designate as the dysfimction of endocrine and nonendocrine systems involving two or more organs on the basis of an autoimmune mechanism. There are 3 types of PGA syndrome and their etiology or pathogenesis is still not complete by understood. Type I PGA is present in the patients who have at least two of the triad of Addison's disease, hypopacathyroidism, and chronic mucocutaneous candidiasis. Type II PGA is present in the those who have Addisons disease with autoimmune thyroid disease and/or insulin dependent diabetes mellitus, but who do not have hypoparathyroidism or candidiasis. Type III PGA is present in the one who have autoimmune thyroid disease, without Addisons disease, but with another autoimmune disease report a case of autoimmune polyglandular syndrome type II in a seventy-three years old female patient who had primary adrenal insufficiency, primary hypothyroidism, and empty sella, pulmonary tuberculosis.

Hepatitis C virus (HCV) E2 protein is known to be one of putative envelope proteins. To develop a sensitive detection method for HCV infected tissues and cells, monoclonal antibodys (MAbs) to the E2 protein of HCV were prepared from mice immunized with recombinant baculovirus-expressing E2 protein (Bac-E2). Several hybridoma clones secreting various levels of MAb were isolated and isotypes of these MAb were determined. One clone (L.2.3.3) was used for ascites production and the E2-MAb was purified and characterized. The L.2.3.3 reacted well with both Bac-E2 and E. coli expressed glutathione-5-transferase-E2 (GST-E2) fusion proteins. Using HCV patient sera, E2 envelope protein was found to be localized in the cell membrane boundary both in CHO cells and insect cells which express HCV E2 protein. Similar result was obtained when same cells were treated with the MAb L.2.3.3. These results demonstrated that Bac-E2 protein is capable of eliciting high titer antibody production in mice.

T cell lymphoblastic lymphoma is characterized by immature lymphoid cells that are indistinguishable from the lymphoblasts and prolymphocytes of acute lymphoblastic leukemia. Several characteristic clinical features of lymphoblastic lymphoma, with include a high male-to-female ratio, a relatively high incidence in older children and young adults, the frequent presence of mediastinal involvement at the time of diagnosis. Also, this disease is rapidly progressive, and early dissemination to the bone marrow, blood, and central nervous system leads to the evolution of a picture resembling a acute lymphoblastic leukemia. We have experienced a rare case of congenital T-cell lymphoblastic lymphoma in which 1/365 year old female newborn had generalized multiple irregular protruding mass on her body. On bone marrow biopsy, CSF analysis, ultrasonogram and whole body MRI studies. We found metastasized tumor mass to, orbit, abdominal cavity, bulva, skin, and lower extremities. Histopathologically, specimen from mass on the right thigh showed diffuse infiltration of poorly differentiated and immature lymphoid cells in the skelectal muscle and subcutaneous soft tissue. By immunophenotyping studies using anti T cell and B cell monoclonal antibody, these cells were reactive with UCHL-1, MB2, but unreactive with MB1, L26. Based on these findings, the lesion was diagnosed as lymphoblastic lymphoma of the T-cell type, which occurred congenitally. Most T cell lymphoblastic lymphoma are noted, but congenital case was not reported. So we report it with a brief review of literature.
