Pillows are known to contain significant levels of indoor allergens and endotoxin, that are of importance to house dust mite sensitized asthmatics. Buckwheat pillows are commonly used in Korea. We studied the levels of the house dust mite allergen, Der f 1, and endotoxin on new synthetic and buckwheat pillows and their accumulation over three months. Endotoxin levels were significantly higher on new buckwheat pillows compared to synthetic pillows; geometric mean levels (95% CI) were 60,950 EU/g (30,270-122,700) and 4,887 EU/g (2,570-9,311) respectively (p<0.001). No Der f 1 was detected on the new pillows. After three months Der f 1 levels were similar on buckwheat and synthetic pillows, geometric mean levels (95% CI) were 1.16 microgram/g (0.02-8.13) and 1.08 microgram/g (0.19-1.68) respectively. These results indicate that buckwheat pillows are a source of very high endotoxin levels that may be of relevance to asthma severity of atopic asthmatics.

PURPOSE: The purpose of this study was to determine whether obesity increases the risk of performing a laparoscopic resection for colorectal cancer. METHODS: Prospectively collected data were obtained for 103 patients who had undergone laparoscopic resection for colorectal cancer from September 2001 to August 2002. Patients who had had a previous abdominal operation, a total colectomy or an additional surgical procedure at the time of colon resection were excluded from the analysis. The patients were divided into two groups based on body mass index (BMI kg/m2): the normal group (BMI <25) and the obesity group (BMI 25). Intraoperative blood loss, operative time, conversion, length of hospital stay and complications were analyzed. RESULTS: Nineteen patients (25%) were obese. Operation time (183.2 min vs 202.1 min) and the blood loss (98.2 ml vs 168.2 ml) were significantly increased in the obese patients, but hospital discharge after surgery (11.7 days vs 11.9 days) and the morbidity rate (8.5% vs 5.3%) were not different between the groups. Conversion to the an open precedure occurred with one obese patient, but that was not related to obesity. In the analysis of the low anterior resection, blood loss (94.6 ml vs 186.6 ml) was significantly higher in obese patients, but no statistically significant differences existed for other surgical outcomes between the two groups. CONCLUSIONS: A laparoscopic resection for colorectal cancer can be safely performed in obese patients.

PURPOSE: This study aimed to assess the oncologic outcomes after a laparoscopic resection in rectal cancer patients with minimum 2-year follow-up. METHODS: Among the 312 patients undergoing a laparoscopic rectal cancer resection between Jan. 2000 and Dec. 2004 at Hansol Hospital, 110 patients who had been followed-up for longer than 24 months (mean 33, range 24~56) after the curative resection were included in this study. Two patients (1.8%) received preoperative chemoradiation. Five patients (4.5%) received radiotherapy postoperatively. RESULTS: TNM stage was 0 in 5 patients, I in 25 (22.7%), II in 35 (31.8%), and III in 45 (40.9%). The T stage was as follows; Tis:T1:T2:T3:T4=4.5%:3.6%:25.5%:40.9%:25.5%. A protective ileostomy was performed in nine patients. The mean operative time was 208 minutes, and the mean blood loss was 179 ml. The mean number of removed lymph nodes was 18, and the mean distal margin was 3.0 cm. The radial margin was positive in one case. Conversion was required in three cases (2.7%). The overall morbidity rate was 17.2%. Anastomotic leak age occurred in five patients (5.5%). There was no operative mortality. During 33 months of mean follow-up, distant metastases and local recurrence were seen in 17 (15.5%) and 5 patients (4.5%), respectively. None had port-site recurrence. For the 94 patients with rectal cancer within 12 cm from the anal verge, the rate of local recurrence was 5.3%. The overall survival rate was 88.9% at 3 years (stage 0, I: 100.0%, stage II: 100.0%, stage III: 72.6%). The disease free survival rate was 78.8% at 3 years (stage 0, I: 100.0%, stage II: 88.6%, stage III: 56.9%). CONCLUSIONS: A laparoscopic resection of rectal cancer provides an acceptable safety profile. If the highly selective indications for radiotherapy (6.3%) and the rather high volume of advanced cancers (stage III 40.9%, T3/4 66.4%) of this study are considered, a 4.5% local recurrence rate is promising. Optimal surgery for rectal cancer by using a laparoscopic technique may reduce the need for radiotherapy.

BACKGROUND: Obesity is related to asthma symptoms and air way hyperresponsiveness. Both asthma and obesity are becoming worldwide chronic health problems. This study was designed to evaluate the association between asthma and anthropometric indices such as body mass index (TMI), body fat percent, and waist-hip ratio (WHR) in Korean adults. METHODS: Three thousand twenty-four subjects aged. 20-79 years, were enrolled in the survey during April - December, 2001. A standardized questionnaire was used to collect general information and asthma symptoms. Obesity was defined as BMI > or =25kg/m2. Over body fat and central obesity was defined as more than 75th percentile of body fat percent and WHR, respectively. RESULTS: The prevalence of asthma in korean adults was 29.6%(male 29.9% and female 29.33%). Asthma was significantly higher in elderly age (> or = 50 years), cigarette smokers. alcohol drinkers. patients with a family history of parent's asthma, and obesity. After adjusting for possible confounders. BMI [OR=1.33 (1.12-1.59)], over body fat [OR=1.28(10.7-1.54)] and central obesity [OR=1.41(1.17-1.70)] remained significant predictors of asthma. CONCLUSION: Our results showed that general obesity and central obesity are potential risk factors of asthma in relatively non-obese korean adults. Cigarette smokers, alcohol drinkers, patients with a family history of parent's asthma, and obesity may aggravate asthma, whereas regular exercise reduces the attacks of asthma.

BACKGROUND/AIM: Colonoscopy has been known as the best diagnostic and therapeutic modality for colorectal polyps. However, it has been difficult to assess its accuracy. METHODS: We studied the data from patients who had colonoscopic polypectomy within 30 days after the initial examination. RESULTS: From 218 patients, a total of 362 polyps were found, 51 (14.1%) of which were missed. There were 17 patients with missed polyps among 59 patients who had two or more polyps on the initial examination. According to the location, the missing rates were variable: the splenic and hepatic flexure had the highest missing rates, and the sigmoid colon had the lowest missing rate. In our study, there was no difference of missing rate according to the size and shape. CONCLUSIONS: There is a significant colonoscopic missing rate for colorectal polyps in routine clinical practice, especially in patients with multiple colonic polyps and at the site of the colonic flexure.

Foreign bodies in the upper esophagus should be removed as soon as possible to avoid serious complications. These foreign bodies can penetrate the bowel wall and cause severe complications. The peristalsis of the esophagus is not strong enough to prevent it from retaining swallowed objects. Hence, perforation from a foreign body is more likely to occur in the esophagus than in the rest of the gastrointestinal tract. A razor blade is a rare foreign body of the esophagus. Its sharpness and large size make it difficult to remove. A razor blade was very firmly impacted in the esophageal wall in our case, and the razor blade had not moved from the upper esophagus. A standard overtube has limitations to remove a razor blade inside the overtube's lumen. We report here on a case of using a wedge resected overtube made it possible to successfully extract a razor blade and no serious complications occurred after extraction of the razor blade.

Ischemic colitis is generally considered a disease of the elderly. The causes of ischemic colitis include low-flow states due to cardiac dysfunction or hypovolemia and certain medications including estrogen. Here we report a case of ischemic colitis in a 26-year-old woman. She had no specific medical history except taking oral-contraceptives for a long time. The mechanism of estrogen-induced ischemic colitis is not clearly understood. But we recommend that oral-contraceptives should be considered as a cause of ischemic colitis in young women.

Eosinophilic fasciitis is a rare disease characterized by diffuse fasciitis with peripheral eosinophilia and progressive induration and thickening of the skin and soft tissues. We report a 19-year-old female who presented with pitting edema in both lower extremities. She had a history of excessive physical activity before her symptoms developed. Physical examination revealed 2+ pitting edema in both lower legs. She complained of mild pain in both knee joints and feet, with no tenderness or heating sensations. Laboratory results were unremarkable except for severe eosinophilia. Parasite infection, venous thrombosis, and cardiac and renal problems were excluded. A magnetic resonance imaging study of both lower extremities revealed increased signal intensity in the subcutaneous lesions, consistent with superficial inflammation of the fascia. Mixed perivenular lymphoplasmacytic and eosinophilic infiltration in the subcutaneous lesion were observed on biopsy. The patient was treated with corticosteroids, resulting in remarkable improvement in both edema and eosinophilia.

Delftia acidovarans is aerobic, nonfermentative Gram-negative rod commonly found in soil and water. Generally it is nonpathogenic but it unusually can cause bacteremia in immunocompromised patients. We present a case of peritonitis due to D. acidovorans in a patient on continuous ambulatory peritoneal dialysis. A 75-year-old woman was admitted with abdominal pain and cloudy peritoneal effluent. She was empirically treated with intraperitoneal (IP) cefazolin and ceftazidime, and then IP ceftazidime and oral ciprofloxacin, but peritonitis did not improve. Seven days after admission, D. acidovorans was identified from the peritoneal effluent, which was sensitive to amikacin, ceftazidime, ciprofloxacin and imipenem. Catheter removal was considered with regard to poor response to adequate antibiotics; however, 4 days after changing to IP imipenem/cilastatin, abdominal pain, the leukocyte count of peritoneal effluent and C-reactive protein decreased. She was treated with imipenem/cilastatin for two weeks and discharged with the dialysis catheter intact.
