PURPOSE: This study was to evaluate and compare the clinical characteristics of a mucinous adenocarcinoma with those of a non-mucinous adenocarcinoma in colorectal cancer patients. METHODS: Data were retrospectively reviewed on 3,232 colorectal cancer patients, including 221 mucinous adenocarcinoma patients (6.1%), who received surgery between 1990 and 2003. RESULTS: The mean tumor size (6.5 cm) of the mucinous adenocarcinomas was bigger than that (5.2 cm) of the non-mucinous adenocarcinomas. The locations of the mucinous adenocarcinomas were 95 (48.2%) in the proximal colon, 35 (17.8%) in the distal colon, and 67 (34.0%) in the rectum whereas those of the non-mucinous adenocarcinomas were 559 (18.9%) in the proximal colon, 861 (29.2%) in the distal colon, and 1,533 (51.9%) in the rectum. Stage distribution was as follows: In mucinous adenocarcinomas, 7 stage A (3.3%), 84 stage B (39.3%), 76 stage C (35.5%), and 47 stage D (21.9%). In non-mucinous adenocarcinomas, 447 stage A (15.2%), 1,036 stage B (35.1%), 997 stage C (33.8%), and 469 stage D (15.9%). In the univariate analysis, the overall 5-year survival rate of patients with a mucinous adenocarcinoma was lower than that of patients with a non-mucinous adenocarcinoma (60% vs. 65%, P=0.016), but survival rates for each stage were not significantly different. The difference in recurrence rates was not statistically significant (33.3% vs. 24.2%, P=0.258). A multivariate analysis showed that the mucinous histologic type was not useful as an independent prognostic factor. CONCLUSIONS: Mucinous colorectal adenocarcinomas tend to be large, exist in a proximal location, have an advanced stage at diagnosis. The difference in survival rates for each stage was not statistically significant. A mucinous histologic type was not an independent prognostic factor.

The majority of flexible bronchoscopies are performed under topical anesthesia with lidocaine being the most commonly used agent. Anaphylaxis rarely occurs after local administration of lidocaine, but can be a fatal complication. We experienced a case of unexpected anaphylaxis. A 66-year-old woman was scheduled for flexible bronchoscopy to evaluate a tracheal mass and stenosis. The oral and nasal mucosa were pretreated with lidocaine. About 2~3 minutes later, the patient developed hypotension and we treated for anaphylaxis in the emergency room. Then, we decided to perform rigid bronchoscopy in this patient, under conditions of general anesthesia. A rigid bronchoscopy was performed in this patient, safely and successfully. The tracheal mass was determined to be squamous cell carcinoma.

Pulmonary hypertension is a frequent complication of chronic obstructive pulmonary disease (COPD) and associated with a worse survival and increased risk of hospitalization for exacerbation of COPD. However, little information exists regarding the potential role of systemic inflammation in pulmonary hypertension of COPD. The purpose of the present study was to investigate the degree of C-reactive protein (CRP) and endothelin-1 (ET-1) levels in COPD patient with and without pulmonary hypertension. The levels of CRP and ET-1 were investigated in 58 COPD patient with pulmonary hypertension and 50 patients without pulmonary hypertension. Pulmonary hypertension was defined as a systolic pulmonary artery pressure (Ppa) > or =35 mmHg assessed by Doppler echocardiography. Plasma CRP and ET-1 levels were significantly higher in patients with pulmonary hypertension than in patients without hypertension. There were significant positive correlations between the plasma ET-1 level and CRP level in the whole study groups. For COPD patients, systolic Ppa correlated significantly with plasma CRP levels and plasma ET-1 levels. These findings support a possibility that CRP and ET-1 correlate to pulmonary hypertension in COPD patients.

Radiation therapy is one of the most important treatment modalities following surgery of the primary malignant or metastatic brain tumors. But radiation can be harmful to normal healthy brain tissues around the tumor. There have been numerous reports of radiation induced damage such as delayed necrosis to human brain after therapeutic exposure. Apoptosis is a form of cell death with morphological and biochemical features that differ from those of necrosis. The aim of this study is to evaluate the apoptosis in normal rat brain after irradiation. Twenty one Sprague-Dawley rats were given a single dose of 10 Gy using high dose rate Ir-192 over 5 minutes at the right frontal region. Apoptosis was evaluated by the TUNEL method(In-situ end labelling technique) and mutant p53 protein, bc1-2 and bax genes were evaluated by immunohistochemical stain. Apoptosis was assessed at 1 week(group A, n=5), 2 week(group B, n=), 4 week(group C, n=), 6 week(group D, n=), 8 week(group E, n=) after irradiation. Apoptosis was noted with 20% of cases(1/5) in group A, 40% of cases(2/5) in group B, 60% of cases(3/5) in group C, 67% of cases(2/3) in group D and 100% of cases(3/3) in group E. Overall apoptosis positive rate was 52.4%(11/21). Apoptosis was most prominently found in external granular and external pyramidal layer(82%, 9/11) and found one case in internal pyramidal layer and the other one case in corticowhite matter junction. There were no positive stainning for mutant p53 protein, bc1-2 and bax gene in all cases pertaining to the phenomenon of apoptosis. In conclusion, apoptosis was evident in the rat brain after irradiation and the incidence of apoptosis was increased with time after irradiation. But the genes related to apoptosis after irradiation were not apparent in this study. Further evaluation including biochemical and clonogenic study needs to clarify the mechanism of apoptosis in normal brain after irradiation.

PURPOSE: To evaluate the frequency, location, and signal intensities of parenchymal (cortical andsubcortical) tubers and white matter lesion, as seen on MR images of patients with tuberous sclerosis. MATERIAL AND METHODS: Twenty patients diagnosed on the basis of clinical and MR findings as suffering from tuberoussclerosis, were retrospectively reviewed. Their ages ranged from 6 days to 21 years (mean, 5.2 years), and theywere divided into two groups according to age : under 18 months (n=9) and over 18 months(n=11). We analyzed thefrequency, location, and enhancement patterns of tubers and white matter lesions, and the difference of signalintensities between cortical and subcortical tubers according to age. RESULTS: Cortical tubers were detected in11 patients (55%), subcortical tubers in 18 (90%), and white matter lesions in 16 (80%). Subcortical tubers weremore frequently noted than cortical tubers and the two types did not always accompany each other. Cortical tuberswere most commonly located in the frontal lobe(10/11), followed by the parietal lobe(2/11), and temporallobe(2/11). Subcortical tubers were also most commonly located in the frontal lobe(17/18), followed by thetemporal lobe(10/18). White matter lesions were also frequently observed in the frontal lobe(13/16) and wererelated to the location of parenchymal tubers in 12 of 16 white-mater lesions. There were no lesions in thecerebellum. The signal intensities of cortical and subcortical tubers were different in all patients. Those ofsubcortical tubers showed no significant difference between the two age groups, but in patients under 18 months,signal intensity on T1WI tended to be high(5/6), and on T2WI, tended to be low(5/6). In 15 patients, Gd-DTPAenhanced MR images showed no demonstrable enhancement, except in one case involving white-matter lesion. CONCLUSION: Both cortical and subcortical tubers were commonly located in the frontal lobe, but the latter weremore frequently observed than the former. Subcortical tubers did not always accompany cortical tubers, and on MRimaging, the signal intensities of the two types were different in all cases. Differentiation of cortical andsubcortical tubers by MR imaging may therefore help analyze the parenchymal tubers seen in tuberous sclerosis.

PURPOSE: The purpose of this study was to describe the MR imaging and CT findings of intracranial inflammatory pseudotumors. MATERIALS AND METHODS: We reviewed the MR imaging (n=8) and CT (n=4) studies of eight patients (M:F = 4:4, mean age: 41 years) with pathologically proven intracranial inflammatory pseudotumor. The findings were then evaluated with regard to location, shape, MR signal intensity, CT density and degree of contrast enhancement of the lesion, surrounding parenchymal edema, adjacent bone change and the location of accompanying extracranial lesion. RESULTS: In two patients, the parietal convexity was involved unilaterally, with no extracranial mass, and in the other six, the middle cranial fossa was involved unilaterally and extracranial mass was present. The lesion also involved the tentorium in four cases, the cavernous sinus in four, the anterior cranial fossa in one, and the posterior cranial fossa in one. The location of extracranial mass was the mastoid and middle ear cavity in two cases, the infratemporal fossa in two, both the infratemporal fossa and paranasal sinuses in one, and the orbit in one. MR images showed diffuse dural thickening in all eight cases, leptomeningeal thickening in four, and focal meningeal-based mass in two. As seen on T1-weighted images, the lesions were isointense to gray matter in eight cases, and on T2-weighted images were hypointense in seven cases and isointense in one. Marked homogeneous contrast enhancement was seen in all eight cases. The lesions seen on brain CT, performed in two cases, were isodense. Adjacent brain parenchymal edema and the destruction of adjacent bones were each seen in five cases. CONCLUSION: The characteristic MR findings of intracranial inflammatory pseudotumors are(1) diffuse dural thickening;(2) a focal meningeal-based mass which on T2-weighted images is seen as hypointense; and marked (3) contrast enhancement : these findings are, however, nonspecific. In order to differentiate these tumors, an awareness of these findings is, however, useful.

Paclitaxel has been widely used for treating many solid tumors. Although colonic toxicity is an unusual complication of paclitaxel-based chemotherapy, the reported toxicities include pseudomembranous colitis, neutropenic enterocolitis and on rare occasions ischemic colitis. Genexol-PM(R), which is a recently developed cremophor-free, polymeric micelle-formulated paclitaxel, has shown a more potent antitumor effect because it can increase the usual dose of paclitaxel due to that Genexol-PM(R) does not include the toxic cremophor compound. We report here on a case of a 57-year-old man with advanced non-small cell lung cancer and who developed ischemic colitis after chemotherapy with Genexol-PM(R) and cisplatin. He complained of hematochezia with abdominal pain on the left lower quadrant. Colonoscopy revealed diffuse mucosal hemorrhage and edema from the sigmoid colon to the splenic flexure. After bowel rest, he recovered from his symptoms and the follow-up colonoscopic findings showed that the mucosa was healing. Since then, he was treated with pemetrexed monotherapy instead of a paclitaxel compound and platinum.
