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: 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.

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.

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.

The pulmonary interstitial emphysema (PIE) is a life-threatening illness in premature infants with mechanical ventilation. While most are managed conservatively, decompression would be necessary. Here, we report the first case of PIE treated by percutaneous catheter insertion in an extremely low birth weight (ELBW) infant in Korea. The patient, born with 660 g in 23+2 weeks of gestation, showed PIE in left lower lung on postnatal day 12. Percutaneous catheter insertion was performed on postnatal day 25. The size of PIE decreased, but didn't disappear completely. On postnatal day 42, we exchanged catheter and inserted additional catheter in pleural space. However, sudden desaturation and pneumothorax occurred on postnatal day 44. We changed catheter in pleural space, and pneumothorax and PIE improved. Finally, we successfully removed catheters, and weaned patient out. As in our case, percutaneous catheter insertion would be a useful option for ELBW infants with PIE.

BACKGROUND: In elderly asthmatics, underdiagnosis is one of the most important feature. The main reason of underdiagnosis is thought to be decreases in complaining of symptoms by reduction of intellectual faculties or physical activity. Among various symptoms, wheezing is the principal clue in diagnosing bronchial asthma, and decreases in wheezing complaints are also noted in elderly asthmatics. The objective of this study is to determine whether decreases in wheezing complaints in elderly asthmatic is due to decrease in the development of wheezing or decrease in the perception of wheezing. METHODS: Sixty one young(20-39 years old), 68 middle aged(40-59 years old), and 65 elderly(older than 60 years) stable asthmatic subjects were studied. During methacholine challenge test, lung auscultation and questionnaire survey about presence and perception of wheezing were conducted. RESULTS: One hundred sixty nine patients (87%) developed wheezing during the methacholine challenge test. Development of wheezing during methacholine challenge test was not different between groups. The methacholine concentration, % fall in FEV1, and FEV1% at first detection of wheezing were not different between groups. Among the patients who developed wheezing, 47 patients (90%), 42 patients (74%), and 26 patients (46%) felt wheezing in young, middle, and old age groups, respectively. CONCLUSION: In conclusion, the perception of wheezing are more decreased in elderly asthmatics compared to those in younger patients.

PURPOSE: The long-term results of a laparoscopic resection for colorectal cancer have been reported in several studies, but reports on the results of laparoscopic surgery for rectal cancer are limited. We investigated the long-term outcomes, including the five-year overall survival, disease-free survival and recurrence rate, after a laparoscopic resection for colorectal cancer. METHODS: Using prospectively collected data on 303 patients with colorectal cancer who underwent a laparoscopic resection between January 2001, and December 2003, we analyzed sex, age, stage, complications, hospital stay, mean operation time and blood loss. The overall survival rate, disease-free survival rate and recurrence rate were investigated for 271 patients who could be followed for more than three years. RESULTS: Tumor-node-metastasis (TNM) stage I cancer was present in 55 patients (18.1%), stage II in 116 patients (38.3%), stage III in 110 patients (36.3%), and stage IV in 22 patients (7.3%). The mean operative time was 200 minutes (range, 100 to 535 minutes), and the mean blood loss was 97 mL (range, 20 to 1,200 mL). The mean hospital stay was 11 days and the mean follow-up period was 54 months. The mean numbers of resected lymph nodes were 26 and 21 in the colon and the rectum, respectively, and the mean distal margins were 10 and 3 cm. The overall morbidity rate was 26.1%. The local recurrence rates were 2.2% and 4.4% in the colon and the rectum, respectively, and the distant recurrence rates were 7.8% and 22.5%. The five-year overall survival rates were 86.1% in the colon (stage I, 100%; stage II, 97.6%; stage III, 77.5%; stage IV, 16.7%) and 68.8% in the rectum (stage I, 90.2%; stage II, 84.0%; stage III, 57.6; stage IV, 13.3%). The five-year disease-free survival rates were 89.8% in the colon (stage I, 100%; stage II, 97.7%; stage III, 74.2%) and 74.5% in the rectum (stage I, 90.0%; stage II, 83.9%; stage III, 59.2%). CONCLUSION: Laparoscopic surgery for colorectal cancer is a good alternative method to open surgery with tolerable oncologic long-term results.

Amyloidosis is a group of disorders characterized by the extracellular accumulation of insoluble, fibrillar proteins in various organs and tissues. It is classified, on the basis of the identity of the precursor protein, as primary, secondary, or familial amyloidosis. Gastrointestinal amyloidosis usually presents as bleeding, ulceration, malabsorption, protein loss, and diarrhea. However, gastric amyloidosis with gastric outlet obstruction mimicking linitis plastica is rare. We report a case of gastrointestinal amyloidosis with gastric outlet obstruction in a patient with ankylosing spondylitis. The patient was indicated for subtotal gastrectomy because of the aggravation of obstructive symptoms, but refused the operation and was transferred to another hospital. Three months later, the patient died of aspiration pneumonia during medical treatment.
