PURPOSE: To obtain the normal standard of the electrocardiogram(ECG) in newborn infants, METHODS: Standard 12-lead ECG recordings of 146 healthy neonates of gestational age above 30 weeks recorded in 24 hours after birth were analyzed for the following parameters: heart rate, QRS axis, PR interval, QTc interval, R and S wave amplitude. RESULTS: The mean gestational age of preterm(between 30 and 37 weeks) and term infants was 33.2 +/-2.4 and 38.4+/-3.2 weeks, and the mean birth weight was 2,168+/-371 g and 3,254+/-436 g, respectively. There was no meaningful difference between two groups in heart rate, PR interval, QTc interval, and QRS axis. Amplitudes of R waves in V1>-V6 leads and S waves in V2, V3 and V5 leads in term baby group were significantly larger than those in preterm baby group. The sum of amplitudes of R and S waves was largest in V2. The amplitude of combined R+S waves in V2 and V3 leads was significantly larger than that in V5 and V6 leads in both groups. This difference was more prominent in tbaby group. CONCLUSION: The results suggest that the increase in cardiac muscular mass and progressive right ventricular predominance are in accordance with the increase in gestational age.

Leiomyomas of vagina and vulva are rare solid tumors, but most common mesenchymal tumors in adult woman. Most of the reported cases have been benign. The tumors were firm, well-defined submucosal masses in a majority of patients. We experienced two cases of vulvar and vaginal leiomyoma, thus it is presented with a brief review of the cases and its literatures.

A umbilical omphalomesenteric duct polyp is the result of incomplete closure of the omphalomesenteric duct, which connects the midgut with the yolk sac of the embryo. It may be associated with underlying embryologic anomalies such as Meckels diverticulum and umbilical enteric fistula, the complications of which may at times be fatal. This rare malformation should be clinically discerned from persistent granulation tissue or pyogenic granuloma. Histologically, it shows a polypoid lesion consisting of ectopic gastrointestinal epithelium with the appearance of gastric, intestinal, or colonic mucosa. We report a case of an umbilical omphalomesenteric duct polyp in an 8-year-old male patient, who had had a bright-red polyp on the umbilicus from the age of 1 month and had not had any other types of underlying abnormalities.

BACKGROUND: A hand hygiene policy has been introduced by the Joint Commission International Accreditation Standards for Hospitals (JCI); the purpose of this policy is to ensure that systematic standards are continuously practiced at hospitals in order to improve the quality of medical care and the safety of patients and health care workers. This policy requires that phlebotomists wear new gloves and disinfect their hands before attending a patient to prevent nosocomial infections and to protect the phlebotomists. This study aimed to assess the responses of patients and guardians regarding the hand hygiene procedures. METHODS: Between January and February 2010, a questionnaire survey was performed at our hospital for 310 outpatients, 93 inpatients, and 189 guardians. RESULTS: In all, 70.8% of respondents answered that phlebotomists did not require considerable time to remove and wear gloves, and 69.9% responded that phlebotomists could readily detect veins even with their gloves on. Besides, 81.9% respondents thought that it was sanitarily important for phlebotomists to remove their gloves and disinfect their hands after a venipuncture, whereas only 2.8% thought that this practice caused discomfort. CONCLUSION: The patients and guardians recognized that the hand hygiene procedures were important for their own safety and encouraged their application rather than considering them uncomfortable or inappropriate. Introduction and maintenance of the hand hygiene policy of JCI would not be difficult because patients or guardians recognized its importance.

A 51-year-old Korean woman presented with a non-tender, well-demarcated, reddish, edematous patch on the right anterior chest where a previous mastectomy and radiation therapy had been performed. She had been diagnosed as having infiltrating ductal carcinoma of the right breast about 1 year ago. Histopathological findings of the skin lesions were consistent with inflammatory metastatic carcinoma of the breast. Inflammatory carcinoma or carcinoma erysipeloides is a well-established entity most frequently associated with carcinoma of the breast. It is characterized by dermal lymphatic invasion by malignancy and clinically should be distinguished from erysipelas or cellulitis. We describe a case of inflammatory metastatic carcinoma derived from an infiltrating ductal carcinoma of the breast which can be clinically confused with radiation dermatitis.

PURPOSE: To determine the detection rate of MRI in the diagnosis of adenomyosis and ascertain the accuracy of MRI in assessing the extent and depth of the myometrial invasion. MATERIALS AND METHODS: By retrospective analysis of MR images of the pelvis in 65 pathologically proven cases of uterine adenomyosis, we investigated the detection rate and differences of in the detection rate when this was based on (a) the extent, and (b) the depth of myometrial invasion. The condition was classified as diffuse or focal according to the extent of invasion, and mild, moderate, or severe according to its depth. RESULTS: Pathologically, there were 35 cases of focal adenomyosis (53.8%), and 30 of diffuse adenomyosis (46.2%). Among patients with the focal variety of this condition, 12 cases were mild, 14 were mild, 14 were moderate, and nine were severe, while among those with the diffuse variety, two were mild, ten were moderate and 18 were severe. A total of 48 cases (73.8%) were detected on MR images; the detection rate of focal adenomyosis was 60.0% (21/35) and that of diffuse adenomyosis was 90.0% (27/30). The detection rates of mild, moderate, and severe adenomyosis were 42.9%(6/14), 79.2%(19/24), and 85.2% (23/27), respectively. Among the 48 cases detected on MR images, the pathologic and MR findings were consistent with regard to both the extent and depth of myometrial invasion in 26(54.2%). For diffuse adenomyosis, the consistency rate was higher than for the focal variety (81.5%, 22/27; compared with 19%, 4/21). The extent of myometrial invasion was correctly evaluated in 32 cases (66.7%); the consistency rate for the diffuse form was higher than for the focal form [96.3% (26/27), compared with 28.6% (6/21)]. In 42 cases (87.5%), the depth of invasion was correctly evaluated, though differences in this depth were not significant. CONCLUSION: MR imaging was a useful imaging modality in the diagnosis of uterine adenomyosis. With regard to the extant of mymetrial invasion, the detection rate was higher among cases of the diffuse form than of the focal form, and with regard to depth, the rate was higher among moderate and severe cases than among mild ones. These findings may be useful for preoperative diagnosis based on clinical symptoms, and provide important yardstick for decisions as to whether hysterectony should be replaced by an alternative therapy.

PURPOSE: Gastric cancer surgery is a common operation in East Asia, such as Korea and Japan, and there has been a significant increase in the need for this procedure due to the aging population. As a result, surgery for the treatment of gastric cancer for elderly patients is expected to increase. This study examined the effect of old age on gastric cancer surgery, and analyzed the operative risk factors for elderly patients. MATERIALS AND METHODS: From November 2008 to August 2010, 590 patients, who underwent a curative resection for gastric cancers, were enrolled. Patients who underwent palliative or emergency surgery were excluded. A retrospective analysis of the correlation between surgical outcomes and age was performed. The elderly were defined as patients who were over the age of 65 years. RESULTS: The mean age of all patients was 58.3 years, and complications occurred in 87 cases (14.7%). The most common complication was wound infection and severe complications requiring surgical, endoscopic, or radiologic intervention developed in 52 cases (8.8%). The rate of complications increased with increasing age of the patients. Univariate analysis revealed age, comorbidity, extent of resection, operation time, and combined resection to be associated with surgical complications. In particular, age over 75 years old, operation time, and comorbidity were predictive factors in multivariate analysis. In the elderly, only comorbidity was associated with surgical complications. CONCLUSIONS: The patients' age is the most important factor for predicting surgical complications. Surgeons should pay an attention to the performance of gastric cancer surgery on elderly patients. In particular, it must be performed carefully for elderly patients with a comorbidity.

PURPOSE: Gap junction intercellular communication(GJIC) is an important mechanism of the bystander effect in herpes simplex thymidine kinase/ganciclovir(HSVtk/GCV) gene therapy Therefore, we attempted to enhance the bystander effect in vitro by exogenous overexpressing connexin 37(Cx37) in cells to increase GJIC. METHODS: NIH3T3 cells were transfected with the Cx37 and HSVtk gene or the HSVtk gene alone by the calcium phosphate method, and we detected their expression from these cells by RT-PCR. GCV-mediated cytotoxicity and the bystander effect of each transfectant was then assessed and compared. RESULTS: Cells transfected with HSVtk became sensitive to low concentration of GCV. We found significantly increased cytotoxicity in HSVtk/GCV gene therapy after introduction of the HSVtk and Cx37 genes together compared with the cytotoxicity seen after introduction of the HSVtk gene in vitro. Co-expression of the HSVtk and Cx37 genes potentiates HSVtk/GCV gene therapy through the bystander effect. CONCLUSION: These results indicated that the increase of GJIC using Cx37 have potentiated the by stander effect of HSVtk/GCV therapy, and may be a new approach to improve response in suicidal cancer gene therapy.
