Differential surgical procedures have been described on the treatment of patients with obstructing carcinoma of the left colon and rectum, and these vary from classical three stage approach to primary resection and anastomosis using intraoperative colonic irrigation or subtotal colectomy. Staged colonic prcedures are associated with significant morbidity and mortality eventhough its initial easy performance, and many patients, unfit for further surgery, are left with a permanent colostomy. We have already reported the initial results of intraoperative antegrade colonic irrigation for one-stage operation in obstructing left colorectal cancers. In this investigation, we evaluated the results of prospective trials of primary resection and anastomosis using intraoperative colon irrigation and subtotal colectomy in obstructing left colon and rectal carcinomas. During recent five years, 19 cases of obstructing left colon and rectal carcinomas which could not received regular colon preparation due to marked abdominal distension were enrolled to this study. There were 12 men and 7 women, and mean age was 61. 14 of the 19 patients which tumors located below mid-descending colon were subjected to primary resection and anastomosis using intraoperative antegrade colonic irrigation, 4 patients which tumors located above the mid-descending colon were treated with subtotal colectomy, and remaining one patient which tumor located upper rectum was performed subtotal coloectomy because of underlying colonic ischemia. There was no mortality and significant postoperative complications such as anastomotic lealrage, pelvic abscess or intraabdominal sepsis which seemed to be related with anastomotic dehiscence. Therefore, primary resection and anastomosis using intraoperative colonic irrigation or subtotal colectomy depending on tumor locations in cases of obstructing left colon and rectal carcinomas might be useful methods to obtain safe one-stage restorative colorectal resections.

PURPOSE: To evaluate the effects of cheap tinted contact lenses on corneal swelling and ocular surface inflammation, compared to hydrogel and silicone hydrogel contact lenses. METHODS: Forty eyes of 20 New Zealand white rabbits were randomly assigned to 4 groups. Two types of tinted contact lenses, hydrogel lenses, and silicone hydrogel lenses were each applied to 10 rabbit eyes. Corneal thickness and tear lactate dehydrogenase (LDH) activity were measured at 1 and 4 days after contact lens wear, and the inflammation of ocular surface was scored at 4 days after contact lens wear. The internal surface of the cheap tinted lens was examined with a scanning electron microscope to compare the surface quality between the tinted and non-tinted area. RESULTS: Although the corneal swelling of the silicone hydrogel lens group was significantly lower than the other 3 lens groups after contact lens wear (p<0.01), the common hydrogel lens group was not different from the 2 tinted contact lens groups (p>0.1). Tear LDH activity at 1 and 4 days after contact lens wear showed no significant difference among the 4 groups (p>0.29). The scores of ocular surface inflammation in the 2 tinted contact lens groups were greater than the hydrogel and silicone hydrogel lens groups (p=0.03). The scanning electron microscope revealed the internal surface of the tinted area in the tinted contact lens was coarse and irregular though the surface of the non-tinted area was relatively smooth. CONCLUSIONS: Regarding corneal swelling and tear LDH activity, the cheap tinted contact lenses used in Korea were not significantly different from the common hydrogel contact lenses. However, tinted contact lenses showed a greater tendency to provoke ocular surface inflammation than other lenses. The coarse and irregular surface of the tinted area in the tinted contact lens appears to play a role in provoking severe ocular surface inflammation.

OBJECTIVE: This study was conducted to elucidate the associations of HLA with systemic sclerosis (SSc) in Koreans. METHODS: HLA associations with SSc according to SSc-specific autoantibody status and clinical subsets (diffuse and limited) were investigated. HLA-A, B, and C antigens were typed by the serological method using microlymphocytotoxicity test, and HLA-DR by DNA typing method using PCR-reverse hybridization and PCR-SSCP in 56 Korean patients with SSc and 226 healthy controls. For SSc patients, anti-Scl-70 and anicentromere antibodies were tested by double immunodiffusion and indirect immunofluorescence, respectively. RESULTS: The results of HLA class I antigen typing showed that the frequencies of HLA-A24, B52 and B62 were increased, whereas those of A33, B44 and B58 were decreased in SSc patients compared to healthy controls. The frequency of HLA-DR2 was significantly increased, whereas that of HLA-DR13 was decreased in patients with SSc compared to controls. Among HLA-DR2 alleles, both HLA-DRB1*1501 and *1502 were increased in SSc patients compared to controls. According to clinical status, HLA-DRB1*1501 was increased in limited SSc patients and that of DRB1*1502 was increased both in diffuse and limited SSc patients compared to controls. According to autoantibody status, HLA- DRB1 1502 was significantly increased in anti-Scl-70-positive SSc patients and that of DRB1 1501 was increased in anti-Scl-70-negative SSc patients compared to controls. The association of HLA-DR2 alleles with SSc according to clinical subsets and anti-Scl-70 antibody status revealed that the frequency of HLA- DRB1 *1501 was significantly increased in anti-Scl-70-negative limited SSc patients compared to controls. CONCLUSIONS: These results suggest that different HLA-DR2 alleles are associated with different types of SSc in Koreans. HLA-DRB1 1502 shows strong association with anti-Scl-70-positive SSc, and DRB1 1501 with anti-Scl-70-negative limited SSc. It is concluded that the pathogenesis of SSc in Koreans is in part, based on the same genetic background.

The effects of treatment with oral capecitabine vs. bolus 5-FU, administered concurrently with preoperative radiotherapy, were compared in the treatment of locally advanced rectal cancer (LARC). One hundred and twenty-seven patients with LARC received concurrent preoperative chemoradiation using two cycles bolus 5-FU (500 mg/m2/day) plus leucovorin (LV, 20 mg/m2/day) (Group I). Another LARC group received concurrent chemoradiation using two cycles 1,650 mg/m2/day of oral capecitabine and 20 mg/m2/day of LV (Group II, 97 patients). Radiation was delivered to the primary tumor at 50.4 Gy in both groups. Definitive surgery was performed 6 weeks after the completion of chemoradiation. A pathologic complete remission was achieved in 11.4% of patients in Group I and in 22.2% of patients in Group II (p= 0.042). The down-staging rates of the primary tumor and lymph nodes were 39.0/ 68.7% in Group I and 61.1/87.5% in Group II (p=0.002/0.005). Sphincter-preserving surgery was possible in 42.1% of patients in Group I and 66.7% of those in Group II (p=0.021). Grade 3 or 4 leucopenia, diarrhea, and radiation dermatitis were statistically more prevalent in Group I than in Group II, while the opposite was true for grade 3 hand-foot syndrome. Preoperative chemoradiation using oral capecitabine was better tolerated than bolus 5-FU and was more effective in the promotion of both down-staging and sphincter preservation in patients with LARC.

PURPOSE: This report outlines the incidence and the clinical features of patients with a neuroendocrine (NE) neoplasm of the colon and rectum and describes, in detail, their histologic and immunohistochemical findings. Also, we attempted to determine the impact of several clinical variables, including tumor stage, tumor location, NE pattern, and cellular subtype on survival. METHOD: Of 690 colorectal cancers operated on from April 1990 to November 1998 at Chungnam National University Hospital, 41 cases were originally diagnosed as poorly differentiated adenocarcinoms on the basis of conventional light microscopy. Paraffin blocks from the aforementioned cases were retrieved, and sections were im munostained with antibodies to human chromogranin A, neuron specific enolase, and synaptophysin. RESULTS: Of the 690 cases of colorectal caner, 35 cases (5.1%) of NE neoplasm were identified retrospectively: 28 males and 7 females. About 90% of the tumors were located at the cecum and the rectosigmoid. Pathologic stages were as follows: modified Dukes stage B2, 6; stage C1, 8; stage D1, 12; and stage D2, 9. The most common metastatic site at the time of diagnosis was the liver (8/9). Four NE patterns were identified: pure NE (n=4), and predominantly NE (n=8), equal NE and exocrine (n=4), and predominantly exocrine (n=19). Two cellular subtypes were identified: well-differentiated (n=3) and intermediate (n=32) cells. Survival statistically correlated with stage (p=0.03), but not with age, sex, tumor location, NE pattern, or cellular subtype. CONCLUSION: This study suggests that NE neoplasms of the colon and rectum are more frequent than previously believed. Since a NE neoplasm is believed to be an extremely biologically aggressive tumor, recognition of a NE neoplasm is very important because of its evident clinical and therapeutic implications.

Primary idiopathic polymyositis is a condition of presumed autoimmune etiology in which the skeletal muscle is damaged by a nonsuppurative inflammatory process dominated by lymphocytic infiltration. We recently experienced a patient with primary idiopathic Polymyositis associated with hypoalbuminemia and thrombocytopenia. About 4 months prior to admission, he was diagnosed as primary idiopathic polymyositis, and improved by treatment with prednisolone 60 mg/day. During steroid tapering, muscle weakness was recurred and accompanied by hypoalbuminemia and thrombocytopenia. Despite retreatment with prednisolone 60 mg/day, muscle weakness, hypoalbuminemia and thrombocytopenia persisted. He was then started to administer methotrexate(MTX) 15 mg/week which resulted in prompt improvement of muscle weakness, hypoalbuminemia and thrombocytopenia. These findnigs suggest that primary idiopathic polymyositis is one of the cause of hypoalbuminemia and thrombocytopenia, and that the hypoalbuminemia and thrombocytopenia can be improved promptly by methotrexate treatment.

BACKGROUND: Intrahepatic stones are common in East Asia and pose serious complications such as biliary stricture, liver atrophy, liver abscess, sepsis and sometimes cholangiocarcinoma. The management of primary intrahepatic stones is difficult and it is also difficult to remove all stones during operation. METHODS: Eighty seven patients with hepatolithiasis were admitted to the department of surgery, Keimyung University Dongsan Medical Center during 4 year period between 1994 and 1997. We reviewed medical records retrospectively for these patients. RESULTS: The peak incidence of age was 50's and the male to female ratio was 1:1.2. Intrahepatic stones were located in the left lobe in 62.1%, right lobe 17.2% and both lobe 20.7%. Stones were found only within the liver (I type) in 34.5% and both inside and outside the liver (IE type) in 65.5%. Analysis of the composition of intrahepatic stones revealed calcium bilirubinate as the most common compound (over 75%) and E. coli was the most common organism in bile culture. We classified intrahepatic stones as four types. Type I (45.9%) is cases with liver atrophy on abdominal CT, type II (20.6%) is cases without liver atrophy as IE type, type III (16.0%) is cases with dilatation of extrahepatic bile duct as I type, and type IV (17.2%) is cases without liver atrophy nor extrahepatic bile duct dilatation. Of the 72 operated patients, liver resection was done in 43 (59.7%) and 9 patients (20.0%) had residual stones. Cholangiocarcinoma was found in 3 (7.0%) of the total 43 patients who underwent liver resection. CONCLUSION: Hepatic resection should be performed in selected patients with intrahepatic stones because of lowest presence of residual stones and no difference of postoprative complications compared with drainage procedure.

PURPOSE: This study describes how often complementary and alternative medical (CAM) therapies, what patterns of CAM therapies utilization, what types of CAM therapies and why CAM therapies are used in children and adolescent with chronic disease. METHODS: We interviewed and filled out questionnaires with parents of patients suffering from asthma, atopic dermatitis, congenital myopathy, epilepsy and so on from Mar 2004 to Aug 2004. RESULTS: Two hundred fifty two parents answered questionnaires; 160 cases (63.5 percent) had used CAM therapies. Utilization of CAM therapies according to each chronic disease was as follows: congenital myopathy (100 percent), atopic dermatitis (91.1 percent), asthma (72.5 percent), chronic diarrhea (50.0 percent), epilepsy (17.1 percent) etc. Types of CAM therapy were as follows: dietary supplement (31.1 percent), herb medicine (23.4 percent), massage (14.2 percent), acupuncture (4.6 percent) etc. Sixty four (40.0 percent) case underwent more than two types of CAM therapies simultaneously. One hundred thirty three (83.1 percent) case were asked through non-medical prescription. Ninety nine (61.9 percent) case were recognized positive effect of CAM therapies. Parents' and childrens' ages were influential factors in CAM therapies utilization: the older the parents and the younger the children, the higher the utilization. CONCLUSION: Although patients receive treatment with western medicine, many of them not only undergo CAM therapies, especially more than two types, but also recognize the positive effects of CAM therapies. As a result, we suggest that it is easy to use of CAM therapies, and the positive effects of CAM therapies are prominent, domestically. Therefore, medical approach and study about the effectiveness and side effects of CAM therapies is necessary to avoid the imprudent use of such therapies.

PURPOSE: Because data as a basis for the determination of proper age and modality for screening of colorectal neoplasms is lacking, we evaluated detection rates and anatomical distribution of colorectal neoplasms according to age in healthy individuals who underwent total colonoscopy for health checkup. METHODS: A total of 16,100 cases that had received the colonoscopic examination from January to December in 2014 were analyzed. The total number of individuals who received total colonoscopy were divided by the number of individuals harboring colorectal adenoma to calculate the detection rate of colorectal adenoma. Individuals ≤50 years old were classified as young-age group and aged >50 were old-age group. Differences in anatomical locations of colorectal neoplasms were analyzed in the 2 age groups by chi-square test. Risk factors for colorectal adenoma in each age group were analyzed using univariate and multivariate logistic regression analyses. RESULTS: Detection rates of colorectal adenoma were 13.7% in all cases and 12.8% for those in their 40′s. The main anatomical location of colorectal adenoma was proximal colon in both age groups (P < 0.001). Hyperplastic polyp was mainly distributed to the distal colon in both age groups (P < 0.001). Distal colon was the major site for colorectal cancer in the old-age group (P = 0.001). Proximal location of neoplasms was a risk factor for colorectal adenoma in both age groups with multivariate analysis. CONCLUSION: These data could be the bases for earlier initiation of screening for colorectal neoplasms with total colonoscopy to detect clinically significant colorectal polyps.
