BACKGROUND AND OBJECTIVES: Being probably of embryonal in origin, the nasolabial cyst is relatively rare and is thought to arise either from the epithelial remnants entrapped along the lines of fusion during the development of face or from the remnants of the developing nasolacrimal duct. The purpose of this study was to examine the clinical and radiological features of nasolabial cyst in order to provide basis for its correct diagnosis and treatment. MATERIAL AND METHODS: The nine cases of nasolabial cyst which were treated in Masan Samsung Hospital from January in 1991 to April in 1997 were the used as subjects. These cases were examined according to age and sex distribution and their clinical features, radiologic and histologic findings, treatment and prognosis, were studied. RESULTS: In our study of nine cases of nasolabial cyst, more females than males were observed, and with respect to age, individuals in their Fortise were more frequently noted. Also, swelling of nasolabial fold were the most frequently observed among symptom and signs. Computerized tomography shows well-circumscribed cystic mass lateral to pyriform aperture. Seven cases underwent operation. Six cases were excised by intraoral sublabial approach, one case which forms fistula to skin was removed by transcutaneous approach. CONCLUSION: Nasolabial cyst is benign harmatomatous cyst of face. This lesion is often unrecognized or confused with other intranasal mass, other fissural and odontogenic cysts, midface infection, or swelling in the nasolabial area. Therefore careful clinical and radiologic evaluation should be considered in the differential diagnosis.

To observe the role of oxygen free radical and enzymatic scavengers in cerebral ischemia, an infarction model was made using transorbital occlusion of the middle cerebral artery in cats. The changes of the superoxide radical production and the activities of superoxide dismutase and catalase were measured. The results were as follows ; 1) The infarction of the left middle cerebral artery(MCA) territory was identified with intracardiac perfusion of a TTC solution after transorbital occlusion. 2) The superoxide radical activities after occlusion of the left MCA were not changed in all groups except for the decrease in 6 hours group of the right side compared to the control group(p<0.05). 3) The Mn-superoxide dismutase activities of the left side in the 12 hours group were significantly higher than those of the right side(p<0.01) and those in the control group(p<0.05). 4) The Cu, Zn-superoxide dismutase activities of the left side in the 3 hours group after occlusion of the left MCA were significantly higher than those in the control group(p<0.05). 5) The catalase activities of the left side in the 3 hours, 6 hours and 12 hours groups after occlusion of the left MCA were significantly higher than those of the right side(p<0.05). 6) The catalase activities of the left side in the 12 hours group after occlusion of the left MCA were significantly higher than those in the control group(p<0.05). The authors suggest that the enzymatic scavangers such as Mn-SOD, Cu, Zn-SOD and catalase increased in the infarcted brain, which means an involvement of free radicals in cerebral infarction.

PURPOSE: Administration of antiretroviral drugs to mothers and infants significantly decreases mother-to-child human immunodeficiency virus (HIV) transmission; cesarean sections and discouraging breastfeeding further decreases this risk. The present study confirmed the HIV status of babies born to mothers infected with HIV and describes the characteristics of babies and mothers who received preventive treatment. METHODS: This study retrospectively analyzed medical records of nine infants and their mothers positive for HIV who gave birth at Korea University Ansan Hospital, between June 1, 2003, and May 31, 2013. Maternal parameters, including HIV diagnosis date, CD4+ count, and HIV ribonucleic acid (RNA) copy number, were analyzed. Infant growth and development, HIV RNA copy number, and HIV antigen/antibody test results were analyzed. RESULTS: Eight HIV-positive mothers delivered nine babies; all the infants received antiretroviral therapy. Three (37.5%) and five mothers (62.5%) were administered single- and multidrug therapy, respectively. Intravenous zidovudine was administered to four infants (50%) at birth. Breastfeeding was discouraged for all the infants. All the infants were negative for HIV, although two were lost to follow-up. Third trimester maternal viral copy numbers were less than 1,000 copies/mL with a median CD4+ count of 325/microL (92-729/microL). Among the nine infants, two were preterm (22.2%) and three had low birth weights (33.3%). CONCLUSION: This study concludes that prophylactic antiretroviral therapy, scheduled cesarean section, and prohibition of breastfeeding considerably decrease mother-to-child HIV transmission. Because the number of infants infected via mother-to-child transmission may be increasing, studies in additional regions using more variables are necessary.

PURPOSE: To evaluate the CT grading of complications developing after endoscopic sphincterotomy (EST), and their clinical course. MATERIALS AND METHODS: We retrospectively evaluated CT in 19 patients in whom pancreatitis or duodenal perforation developed after EST in 594 patients. The CT grading of pancreatitis was classified as mild, moderate or severe, according to the extent of peripancreatic infiltration; duodenal perforation was classified as mild, moderate or severe grade, according to the extent of fluid collection. We attempted to correlate CT grade with the average duration of hospitalization after EST, treatment method and mortality. RESULTS: Post-EST complications detected on CT were pancreatitis (ten patients, 1.7%) and duodenal perforation (nine patients, 1.5%). In those with pancreatitis, hospitalization after EST lasted an average of nine days in mild cases (n=2), 21 days in moderate (n=1) and 41 days in severe (n=7). Nine of ten patients with pancreatitis were treated conservatively, while the other, whose grade was severe, underwent percutaneous drainage. Eight of these ten recovered; the two who died were severe grade patients, one having been treated conservatively and the other by percutaneous drainage. In patients with duodenal perforation, hospitalization after EST lasted an average of 13 days in mild cases (n=2), 16 days in moderate (n=2) and 37 days in severe (n=5). Four of nine patients with duodenal perforation were treated conservatively, while the other five (severe, four; moderate, one) underwent percutaneous drainage. One patient, graded as severe, expired, but the remaining eight rocovered. Percutaneous drainage was performed mostly in severe grade cases, and among patients thus graded, only three (3/594; 0.5%) died. CONCLUSION: CT is considered useful for predicting the clinical course and prognosis of complications occurring after EST.

We report a case of histopathologically confirmed hepatic angiosarcoma. A 29-year old patient was admitted with fever and palpable tender mass in the right upper abdomen. On ultrasonography, a large, well circumscribed mixed echoic mass was seen in the right lobe of the liver. On CT scan, irregular enhancement was seen mainly in the peripheral portion of the mass ; the central portion was not enhanced. The mass showed low signal intensity on T1W1, and high signal intensity on T2WI. Peripheral nodular enhancement was noted on Gd-enhanced MR images; In the peripheral portion of the mass,

PURPOSE: It is difficult to predict volume responsiveness in hemodynamically unstable patients with spontaneous breathing activity. Our objective was to test whether the respiratory variations in pulse oximetry plethysmography (POP) waveform amplitude could predict fluid responsiveness to fluid resuscitation (FR) in spontaneously breathing adult shock patients. METHODS: We investigated 21 patients presenting with shock in the Emergency Room. We assessed hemodynamic status and calculated the respiratory variations in POP waveform amplitude before and after FR. Heart rate, blood pressures (MAP, SBP), maximal POP (POPmax), minimal POP (POPmin) and deltaPOP, defined as deltaPOP = (POPmax - POPmin) / ([POPmax + POPmin] / 2) were recorded. We measured hemodynamic parameters by doppler ultrasound, USCOM(R). RESULTS: Comparisons of hemodynamic parameters between before and after FR showed no significant difference in heart rate, but POP showed significant differences in changes in SBP, MAP, cardiac index, stroke volume index and respiratory variations. In response group(> or =15% in delta CI), the change in cardiac index, stroke volume index, and the respiratory variation in the POP were not significantly different. CONCLUSION: In spontaneously breathing patients with shock, we suggest that delta POP is not a reliable parameter in the prediction of fluid responsiveness.
