The purpose of this study is to evaluate the relationship between arterial and end-tidal CO2 tension during general anesthesia. Sixty one patients age 21~40 years old without history of cardiopulmonary disease in American Society of Anesthesiologists physical status 1, were studied. Thoracic or upper abdominal operations were excluded in this study. Anesthesia was maintained by halothane, nitrous oxide and oxygen. Respirations were controlled in all patients with a Dameca ventilator and minute volumes were adjusted to provide FECO2 levels considered appropriate by anesthetist. The concentration of end-tidal carbon dioxide was continuously monitored with ENGS TROM ELIZA DUO CO2 and O2 analyzer. The radial artery was punctured 30 minutes after the surgical incision and 7oth arterial and endtidal carbon dioxide tension were measured simultaneously. The results were as follows : 1) The mean arterial to end-tidal CO2. tension difference was 2.5+/-3.9 torr. 2) There was a constant correlation between arterial and end-tidal CO2 tension regardless of the degree or minute volume. 3) There was no significant correlation 7etween smokers and non-smokers in male patients.

OBJECTIVE: To evaluate the result of the human papillomavirus (HPV) DNA polymerase chain reaction (PCR) in comparison with cervical cytology for the detection of cervical intraepithelial neoplasia (CIN) and invasive cancer, and to establish the more economic and effective screening method for CIN and invasive cancer. METHODS: HPV DNA PCR test and cervical cytology were applied to 476 women, who were referred for abnormal cytology from April 2004 to March 2005 at National Health Insurance Corporation Ilsan Hospital. The results of both procedures were compared with the results of the histological diagnosis and we calculated and compared the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of cytology, HPV DNA PCR, and their combination, respectively. RESULTS: The sensitivity, specificity, PPV and NPV for the detection of CIN or higher lesion were 98.3%, 64.4%, 82.4%, and 95.7% for HPV DNA PCR; 82.9%, 72.9%, 83.8% and 71.7% for cytology; 100%, 48.6%, 76.7%, and 100% for the combination test. The sensitivity and NPV value of cytology showed statistically significant differences (p<0.05) compared with those of HPV PCR and combination test. The PPV value of combination test showed statistically significant difference compared with those of cytology and HPV PCR. The specificity of three tests were alike (p>0.05). The sensitivity of three tests for the detection of CIN 2, 3 or higher lesion showed no statistically significant differences. CONCLUSION: The routine application of HPV DNA PCR or combination test as a screening tools for the detection of CIN and invasive cancer seems to be inappropriate in view of effectiveness. But the HPV DNA PCR can be used as a valuable adjunct to cervical cytology for the triage of women with minimal abnormality in her cytology to determine the treatment and follow-up plan.

Bednar tumor was described by Bednar in 1957. The histologic pattern of this tumor shows similar to dermatofibrosarcoma protuberans (DFSP) but melanin pigments are scattered within the tumor, It's rare neoplasm accounting for approximately 1-5% of all case of DFSP. Clinically, this tumor is considered to be intermediated malignancy, because of slow growth and frequent local recurrence and lack of distant metastasis. The majority are located on the trunk and the upper and lower extremities, but extremely rate in the head and neck area. Microscopically, this tumor is characterized by tight storiform spindle cells and long slender cells that admixed with a small population of melanin containing dendritic cells. This dendritic cells are the primary features distinguising this lesion from conventional DFSP. Complete surgical excision and close follow-up case are necessany for this neoplasm because of probable intermediate malignancy. A patient was admitted to Our Department of Oral and Maxillofacial Surgery due to swelling on right parotid area and numbness of the right lower lip on September, 1994, By clinical examinations and C-T finding, we dignosed tentatively as myxoma or pleomorphic adenoma. Surgical excision of this tumor was performed with parotidectomy and mandibular osteotomy under the frozen biopsy. By final microscopic and electromicroscopic examination and immunohistochemical study, this tumor was diagnosed as Bednar tumor. So, we report a case of pigmented DFSP with review of literatures.

PURPOSE: Poisoning represents one of the most common accidents encountered by young children. Recently, mortality due to poisoning has gradually decreased, but the incidence has not decreased. We performed this study to compare the following factors during 1980's and 1990's : sex distribution, urban and rural distribution, causative substances. METHODS: A clinical study was performed on 90 cases of acute poisoning who were admitted in the pediatric department of Cho Sun University Hospital from Jan. 1980 to Aug. 1995. RESULTS: 1) The poisoning occured more frequently in males than in females, and the highest incidence was observed in the 1 to 5 year age group(50.0%). 2) Seasonal incidence was more prevalent in summer(from June to August). 3) The frequency of poisoning in the country was higher than in urban, but no significant difference between urban and the country in 1990s. 4) The causative substances were agricultural chemicals(36.7%), drugs(23.3%), household inseticide(21.1%). 5) In 1990s, poisoning due to houshold insecticide was decreased, whereas poisoning due to drug increased. 6) The cause of poisoning was mainly accidental(82.2%). 7) Accident was the leading cause of poisoning in children up to 10 years old, whereas suicidal attempts happened at the 10 to 15 year age group. 8) Death in the hospital was one case(1.1%). CONCLUSIONS: Urban incidence gradually increased and accidental poisoning due to medicine also increased. So, we conclude that prevention such as education and use of grip-tight cap or similar safety devices is important.

We here report the first outbreak caused by rotavirus G11,P[25] in Korea in 2018, representing a case of re-assortment with pig-derived rotavirus. The genotype constellation was identical to the virus identified in Korea in 2012 as G11-P[25] -I12-R1-C1-M1-A1-N1-T1-E1-H1. The infection source was not known exactly but it must be considered infection from swine.

Craniocerebral gunshot injuries (CGIs) are extremely seldom happened in Korea because possession of individual firearm is illegal. So, CGIs are rarely encountered by Korean neurosurgeons or Korean trauma surgeons, though in other developing countries or Unites states of America their cases are indefatigably increasing. Management goal should focus on early aggressive, vigorous resuscitation. The treatments consist of immediate life salvage through correction of coagulopathy, intracranial decompression, prevention of infection and preservation of nervous tissue. There have been few studies involving penetrating CGIs in Korea. Here we present a case of penetrating gunshot wound in Korea. We present a 58-year-old man who was unintentionally shot by his colleague with a shotgun. The patients underwent computed tomography (CT) for assessment of intracranial injury. The bullet passed through the left parietal bone and right lateral ventricle and exited through the posterior auricular right temporal bone. After CT scan, he arrested and the cardiopulmonary resuscitation was conducted immediately. But we were unable to resuscitate him. This case report underscores the importance of the initial clinical exam and CT studies along with adequate resuscitation to make the appropriate management decision. Physicians should be familiar with the various injury patterns and imaging findings which are poor prognostic indicators.

On October 4, 2018, an outbreak of gastroenteritis associated with sapovirus occurred among elementary school students in Gyeonggi-do, Korea. Epidemiologic studies were conducted in a retrospective cohort approach. Using self-administered questionnaires, we collected information on symptoms and food items consumed. Of the 999 subjects, 17 developed patients that met the case definition. The main symptom was vomiting (100%), and the symptomatic age was 6-12 years. Positive samples were identified by conventional reverse transcription polymerase chain reaction for sequencing. They were classified into genotype GI.3 by phylogenetic analysis. This is the first report of an outbreak associated with sapovirus GI.3 in Korea.

Non-Hodgkin's lymphoma presented as a malignancy of the uterine cervix is exceedingly rare disease and accounts for approximately only 0.12-0.6% of extranodal lymphomas. Most reported cases were B-cell lymphomas and there is no consensus on the management and prognosis of the disease because of its extreme rarity. Primary T/natural killer (NK)-cell lymphoma arising from the uterine cervix is scarcely encountered that, in the review of literature, only 1 case has been reported by Mhawech et al. We encountered a woman with T/NK-cell lymphoma involving the uterine cervix that initially presented with severe vaginal bleeding. Therefore, we report the case with a brief review of literature.
