PURPOSE: We reported the CT and MR findings of 2 cases with Sturge-Weber syndrome which were not accompanied by facial nevi. MATERIALS AND METHODS: They were examined with both CT and MR in one case and with MR only in the other case. RESULTS: CT was better than MR in the demonstration of the characteristic cortical calcification. MR was superior to CT in the depiction of the abnormalities of the surrounding parenchyma and the intense enhancement of pial angiomatosis with Gd-DTPA enhancement. CONCLUSION: Gd-DTPA enhanced MR imaging could be useful in the demonstration of the presence and extent of pial angiomatosis in patients with suspected Sturge-Weber syndrome.

The objective of this study was to evaluate the prevalence of asthma, allergic rhinitis, and atopic dermatitis, as well as the risk factors of wheezing among young adults in the Korean military. Young military conscripts in five areas completed a modified International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. For subjects with current wheeze in one sample area, baseline spirometry and bronchodilator response were measured. For subjects without a significant response to bronchodilator (improvement in FEV1 of more than 200 mL and 12%), methacholine challenge tests (MCT) were also performed. Of 3,359 subjects that completed the questionnaire, 354 (10.5%) had current wheeze, 471 (14.0%) had current allergic rhinitis, and 326 (9.7%) had current eczema. Current wheeze was associated with family history of allergic disease, overweight, current smoking, allergic rhinitis, and atopic dermatitis. Of 36 subjects with current wheeze who underwent PFT with or without MCT in the Anyang area, 24 (66.7%) were confirmed to have current asthma. In conclusion, the prevalence of allergic disease in young adults of Korean military is not low, and the risk factors of wheezing include family history of allergic disease, overweight, current smoking, allergic rhinitis, and atopic dermatitis.

OBJECTIVES: Since the 1990s, drug-resistant bacteria have become common pathogens of hospital-acquired infections. In recent years, healthcare-associated infections have come to the fore, and it is reported that distribution rates of these bacteria are comparable to those of hospital-acquired infections. However, there have been few studies on differences in resistant bacteria depending on the size of hospitals. Thus, the authors studied differences in drug-resistant bacteria between a tertiary hospital and smaller medical institutions. METHODS: We retrospectively analyzed the clinical findings and sputum culture results of patients transferred from tertiary hospitals (group A, n=74) and those transferred from smaller medical institutions (group B, n=65). RESULTS: The number of patients with malignancy was higher in group A than in group B. The length of intensive care unit stay was longer in group A than in group B. Antibiotic therapy and mechanical ventilation were more frequently used in group A than in group B. There were no significant differences between the 2 groups in bacterial species (Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa) and their resistance rates to carbapenem, while there were significant differences between the 2 groups in the bacterial species (Acinetobacter baumannii) and its resistance rate to carbapenem. CONCLUSION: In this study, there were significant differences between the 2 groups in the bacterial species and resistance rates to carbapenem for A. baumannii infection unlike other bacterial infections. Further studies on risk factors and patient classification are needed to confirm our results.

PURPOSE: The purpose of this study is to assess the periopertive morbidity and mortality rates in relation to the principal variables in aged patients who undergo laparoscopic colorectal resection. METHODS: From March 2001 to March 2006, the prospective laparoscopic colorectal resection database was used to identify 233 patients. Among them, 132 were 70 years of age or older and they were classified as the aged group. 101 were younger than 70 years of age and they were classified as the younger group. RESULTS: Comorbidity was more common in the aged group than in the younger group (67.4% and 53.5%, respectively) (P=0.030). There were higher ASA scores in the aged group (I: 2.3% II: 68.2% III: 29.5%) than in the younger group (I: 27.7% II: 56.4% III: 15.8%) (P<0.0001). There was a higher postoperative complication rate for the aged group than for the younger group (25.0% and 8.9%, respectively) (P=0.002). Only one case of mortality (0.8%) was found in the aged group. The period of the postoperative hospital stay was longer for the aged group than that for the younger group (21.9+/-3/416.3 days and 16.3+/-3/48.1days, respectively) (P= 0.002). For the aged group, univariate analysis revealed that the operative procedure, disease, the T stage and the operation time were significant variables for the postoperative complications, and multivariate analysis identified the operation time as an independent variable faor the postoperative complications. CONCLUSION: More prudent care is needed to prevent postoperative complications for the aged patients who undergo laparoscopic colorectal resection, and particularly for those who can be expected to have a longer operation time.

PURPOSE: We experimentally induced hepatic infarction in rabbits to evaluate MR findings of liver parenchyma and capsule and its changes with time and to confirm the capsular structure correlating with its histologic findings. MATERIALS AND METHODS: After ligation of hepatic artery, vein and duct of right inferior posterior lobe of liver, T1, T2 weighted and enahnced T1 weighted image were obtained at several time intervals. Histologic samples were taken of two rabbits or more at each time intervals. RESULTS: During the first several days, the signal intensity of the ischemic necrosis showed strong high signal intensity relative to normal liver on both T1 and T2 weighted images. After 2 weeks however, the necrotic areas gradually changed to isointensity or low signal intensity. Capsular structure was observed as slightly high signal intensity compare to ischemic areas on both enhanced T1 and T2 weighted images in six cases, and five cases of 12, respectively. From the first day, homogeneous coagulation necrosis without hemorrhage or liquefaction was observed. Fibrous thickening with rich vascularity was observed along the surface of the necrotic area after two weeks. CONCLUSION: During the first several days, the signal intensity of the ischemic necrosis showed strong high signal intensity on both T1 and T2 weighted images and gradually changed to isointensity or low signal intensity. Liver capsule was shown and slightly high signal intensity along the surface of the necrotic area and could be explained by fibrous thickening of the liver capsule end the rich vascularity within in it.

PURPOSE: The aim of this study was to assess the feasibility and safety of laparoscopic multivisceral resection of colorectal cancer adherent to adjacent organs. METHODS: We reviewed retrospectively 32 patients undergoing elective laparoscopic multivisceral resection for colorectal cancer adherent to adjacent organs between June 2003 and May 2009. Survival curves were generated by Kaplan-Meier method. RESULTS: The median age of 32 patients was 73 years. In 10 of 17 rectal cancer patients (59%), neoadjuvant chemoradiation was performed. All the surgeries were completed laparoscopically. The postoperative complications occurred in 21.9% and there was no operative mortality. The median length of hospital stay was 15.5 days. In 23 of 32 patients (72%), the resection was considered curative. Median follow-up period of all patients and curatively resected patients was 22 (range, 2~65) months, 34 (range, 4~65) months respectively. Local recurrence rate, the 3-year overall survival rate and the 3-year disease free survival rate of 23 curatively resected patients was 4.3%, 92.9% and 84.4%, respectively. CONCLUSION: Laparoscopic multivisceral resection is feasible and safe in highly selected patients with colorectal cancer adherent to adjacent organs. Further validation is needed.

PURPOSE: The purpose of this study is to evaluate the risk factors for clinical anastomotic leakage after laparoscopic resection for rectal cancer. METHODS: From March 2001 and February 2006 in Seoul Veterans' Hospital, the prospective laparoscopic colorectal resection database identified 101 patients who a had laparoscopic rectal resection with colorectal or coloanal anastomosis. The associations between clinical anastomotic leakage and patient-, tumor-, surgery- and laparoscopic-related variables were studied. RESULTS: The rate of clinical anastomotic leakage was 4 percent (4 of 101). The patient-related variable significantly associated with clinical anastomotic leakage was preoperative radiotherapy. The surgery-related factor that turned out to be significant was anastomosis situated less than 5 cm from the anal verge. No tumor- or laparoscopic-related variables were significantly associated with clinical anastomotic leakage. CONSLUSIONS: A protective ileostomy should be considered after a laparoscopic rectal resection for an rectal cancer for anastomosis situated less than 5 cm from the anal verge, particularly when preoperative radiotherapy is being used.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be detected via a nasopharyngeal swab and in sputum, blood, urine, and feces. However, there is only limited data on the real-time reverse transcriptase polymerase chain reaction (RT-PCR) results of coronavirus disease 2019 (COVID-19) patients with pleural fluid. We report a case of COVID-19 with SARS-CoV-2 detected in both sputum and pleural fluid. A 68-year-old male patient came to the hospital with a chief complaint of dyspnea. He was diagnosed with lung cancer. A biopsy was performed, and a pneumothorax was found. As a result, a chest tube was placed into the right pleural space. During his hospital stay, the patient was confirmed as COVID-19 positive. We identified the presence of SARS-CoV-2 through real-time RTPCR assay from the pleural fluid. Although pleural effusion is an uncommon finding in the COVID-19, care should be taken to avoid exposure when handling the pleural fluid sample.

PURPOSE: The aims of this study were to examine the feasibility of sentinel lymph node (SLN) biopsy using the day-before-surgery or the same-day subareolar injection of (99m)Tc-Tin colloid, and to evaluate the accuracy of performing intraoperative multiple frozen section diagnosis of the SLN for breast cancer. METHODS: From Jul. 2003 to Feb. 2004, a total of 81 women with clinically node negative breast cancer underwent SLN biopsy and this was followed by axillary lymph node dissection at the Korea Cancer Center Hospital. 2-2.5mCi of (99m)Tc-Tin colloid was injected intradermally in the outer upper edge of the areola on the day before or the same day of surgery, and lymphoscintigraphy was then obtained. The time interval between the injection of tracer and SLN biopsy varied from 1 hour to 20 hours. Intraoperatively, the status of the SLNs was examined by multiple frozen section diagnosis and all the SLNs were subjected to serial sectioning for Hematoxylin-eosin staining and immunohistochemical staining for cytokeratin. After removal of the SLNs, standard level I and II axillary dissection was performed in all patients. RESULTS: In 26 patients (32.1%), the SLNs were positive for tumor cells among these 26 patients. 16 patients (61.5%) results showed that the SLNs were the only metastatic nodes. Two cases of false negative findings were identified. The sensitivity and specificity were 92.9% and 100% respectively. In the second half of this study, no false-negative cases were found in 41 consecutive patients. CONCLUSION: The results of SLN biopsy using the day-before-surgery or same-day subareolar injection of (99m)Tc-Tin colloid were excellent for identification of the SLNs. This technique does not interfere with effective treatment in the operating room because the time interval between the injection and surgery did not affect the results of SLN biopsy. Intraoperative multiple frozen section diagnosis of SLNs was readily available, and this was highly accurate for assessing the status of SLNs
