Journal of the Korean Cancer Association 1999;31(6):1101-1111
PURPOSE: The purpose of this study was to determine whether Fas-L expression is associated with increased apoptotic induction of tumor-infiltrating lymphocytes (TIL) in human gastric carcinomas. MATERIALS AND METHODS: The author analysed 38 cases of early gastric carcinoma (EGC) and 61 cases of advanced gastric carcinoma (AGC) who received gastric resection, in whom the number of diffuse type was 38 cases and the number of intestinal type was 61 cases. The author used immunohistochemical staining for Fas, Fas-L and CD45, and TUNEL in situ apoptosis detection kit. TIL were detected by CD45 and apoptosis of TIL were detected by CD45 expression and TUNEL positivity on serial histologic sections. RESULTS: Fas-L was localized to neoplastic cells in 61% (23/38) of EGC group and 66% (40/61) of AGC group. The extent of Fas-L expression was variable, with both Fas-L positive and negative neoplastic region occuring within tumors. TIL adjacent to Fas-L expressing tumor region were decreased in number and TIL adjacent to FasL-negative tumor region were increased in number; apoptotic induction of TIL showed just the opposite pattern (p<0.05). Fas expression was found essentially homogeneously throughout the tumor mass independent of tumor stage. Fas expression showed 64% (39/61) of intestinal type and 68% (26/38) of diffuse type. Labeling indices for tumoral apoptosis in EGC and AGC were 6.72% and 7.13%, respectively and this difference was statistically insignificant. Co-expression of Fas-L and Fas, which occurred over large areas of the tumors, did not result in an enhanced rate of tumor cell apoptosis. In addition, factors such as tumor stage and other prognostic factors were not concerned in Fas and Fas-L expression, number of TIL and apoptotic induction. CONCLUSION: These findings suggest Fas-mediated apoptotic depletion of TIL in response to Fas-L expression by stomach cancers, and provide the evidence to support the Fas counterattack as a mechanism of immune escape in gastric cancer. In addition, gastric carcinoma cells of the intestinal and diffuse type did not differ in their expression of the apoptotic receptor Fas.

BACKGROUND: This study was conducted to compare the clinical and radiological outcomes of the locking hook plate fixation (HP) technique and the single tight rope (TR) technique applied for acute high-grade acromioclavicular (AC) joint separations. METHODS: Between 2009 and 2014, 135 consecutive patients with acute AC joint separation Rockwood types III, IV, and V were subjected to surgical reconstruction. One hundred fourteen patients (84.4%) were available for retrospective evaluation. Of them, 62 and 52 were treated using the single TR group and clavicular HP group techniques, respectively. The visual analogue scale, Constant, American Shoulder and Elbow Surgeons (ASES), and Taft scores were used for clinical assessment. Postoperative shoulder range of motion was also assessed. An anteroposterior radiograph of the coracoclavicular distance (CCD) was obtained to evaluate the radiographic signs of recurrence. RESULTS: The TR group patients had better Constant, ASES, and Taft scores than the HP group patients. The loss of reduction in terms of the CCD did not differ between groups. Subacromial osteolysis was observed in 34.6% of the cases in the HP group. However, there were no significant differences in the clinical outcomes between the patients with and without osteolysis in the HP group. Subcoracoid osteolysis, drill tunnel widening, and metal displacement were observed in 3.2%, 22.6%, and 4.8% of the cases in the TR group, respectively. CONCLUSIONS: The single TR technique was relatively more effective at treating acute high-grade AC joint injuries than the HP fixation technique (level of evidence: therapeutic; retrospective comparative study, Level III).

PURPOSE: We evaluated the correlation between the carcinogenesis of gallbladder and the expression of lysozyme, p53, c-erbB2 and CEA in gallbladder lesions. MATERIALS AND METHODS: Thirty cases of gallbladder lesions (containing 17 cases of GB carcinoma) were examined. We analyzed the clinicopathologic findings of the early (stage I & II) and advanced carcinoma (stage III, IV & V) and those of carcinoma with or without metaplasia in the tumor. We performed p53, c-erbB2 and CEA immunohistochemical staining and compared their findings with those of normal mucosa and preneoplastic lesions. We also performed lysozyme immunohistochemical staining and compared its finding with metaplastic and non-metaplastic lesions. RESULTS: There are two distinct genetic pathways in gallbladder cacinogenesis and metaplastic carcinoma was more frequent than non-metaplastic carcinoma. Metaplasia of gallbladder did not reveal any difference of the clinicopathologic findings and depth of invasion (Nevin stage). Lysozyme expression was found in all metaplastic lesions but non-expression did not indicate non-metaplastic lesions. p53 mutations and c-erbB2 alterations may have a role in the carcinogenesis of gallbladder carcinomas, especially, in a late event, and in an early and late events, respectively. The correlation of p53 and c-erbB2 expressions was found but which did not indicate that the co-expression was needed in the carcinogenesis. CEA immunohistochemical staining may be helpful in the differential diagnosis of benign lesions and precancerous and cancerous lesions of the gallbladder. CONCLUSION: These results suggest that p53 mutations and c-erbB2 alterations may have a role in the carcinogenesis of gallbladder carcinomas, especially, in a late event, and in an early and late events, respectively.

Thirteen patients were operated for cubital tunnel syndrome and followed for an average of 26 months postoperatively. Ten patients had a history of relevant trauma and three patients had degenerative osteoarthritis of the elbow. The average duration of symptoms was 18 months (range, 2 to 96 months). Diagnosis was made by physical examination, electromyography and nerve conduction study. Among these, nerve conduction study was found to be the most valuable diagnostic method for the patients with atypical clinical findings. Most of the operations were performed by anterior transposition of the ulnar nerve. At the most recent follow-up, the result was excellent in two patients, good in eight, and fair in three; thus ten patients(77%) showed satisfactory results. The rating system for ulnar neuropathy based on sensory, motor dysfunction and pain was useful for evaluating the operative results. The postoperative gain of score for pain and sensory function were larger than that of motor function. Factors known to influence the result of the operation (age, duration of symptom, history of trauma, method of operation) did not effect the outcome in this study. For successful operation, the ulnar nerve must be thoroughly examined, all possible levels of compression must be released and new foci of compression must be created.

BACKGROUND: Human metapneumovirus (hMPV) is a relatively recently identified respiratory virus that induces respiratory symptoms similar to those of respiratory syncytial virus infection in children. The characteristics of hMPV-infected adults are unclear because few cases have been reported. METHODS: We conducted a retrospective review of hospitalized adult patients with a positive multiplex real-time polymerase chain reaction assay result from 2012 to 2016 at a single tertiary referral hospital in South Korea. We analyzed clinical characteristics of the enrolled patients and divided patients into an acute respiratory distress syndrome (ARDS) group and a non-ARDS group. RESULTS: In total, 110 adults were reviewed in this study. Their mean age was 61.4 years, and the majority (n = 105, 95.5%) had comorbidities or were immunocompromised. Most of the patients had pneumonia on chest X-ray (n = 88, 93.6%), 22 (20.0%) had ARDS, and 12 (10.9%) expired during hospitalization. The mortality rate for patients with ARDS was higher than that of the other patients (36.4% vs. 5.7%, P = 0.001). The risk factor for hMPV-associated ARDS was heart failure (odds ratio, 5.24; P = 0.044) and laboratory values were increased blood urea nitrogen and increased C-reactive protein. The acquisition site of infection was divided into community vs. nosocomial; 43 patients (39.1%) had a nosocomial infection. The risk factors for nosocomial infection were an immunocompromised state, malignancy and immunosuppressive treatment. CONCLUSIONS: These data suggest that hMPV is one of the important respiratory pathogens important respiratory pathogen that causes pneumonia/ARDS in elderly, immunocompromised individuals and that it may be transmitted via the nosocomial route.

PURPOSE: Patency of the arteriovenous fistula remains the most important support for patients with end stage renal disease. Prosthetic materials have been used only when autogenous arteriovenous fistula procedure is not feasible, because of the relatively low patency in prosthetic arteriovenous fistula. We designed this study to determine the appropriateness of primary prosthetic arteriovenous fistula. METHOD: Twenty-one consecutive patients who underwent prosthetic arteriovenous fistula formation on the arm in Chosun university hospital from Mar. 1998 to Feb. 2001 were retrospectively analysed. RESULT: The median patency in radio-antecubital fistula, brachio-antecubital fistula, and brachio-axillary fistula was 9.6, 11.4, and 16.6 months, respectively. The primary assisted patency rates in radio-antecubital fistula and brachio-antecubital fistula were 44.9% and 70.0% at the first year, respectively (P=0.03). The secondary patency rates in radio-antecubital fistula and brachio-antecubital fistula were 71.4% and 80.0% at the first year and 28.6% and 48.0% at the second year, respectively (0.02). CONCLUSION: The patency rates according to the site of prosthetic arteriovenous fistula were statistically significant in the radio-antecubital fistula and brachio-antecubital fistula groups. Nevertheless, the patency rates of the brachio-axillary fistula group were statistically insignificant. Primary brachio-antecubital fistula with PTFE creation showed favorable patency rates and many other benefits. Therefore, we suggest primary brachio-antecubital fistula with PTFE as the appropriate arteriovenous access in patients with poor vessel condition.

Trauma is one of the causes of lymphedema. However, we usually do not consider it as a cause of the lymphedema, thus, we often fail to take care of the patients properly. We report a patient with post traumatic lymphedema and the result of complex decongestive therapy, and reviewed the clinical, lymphoscintigraphic findings and treatment.

PURPOSE: The Pediatric Risk of Mortality(PRISM) III score was developed from the Physiologic Stability Index(PSI) to assess pediatric ICU mortality and Provide an objective data as a severity index. Although the PRISM score has been applied to many comparisions and analyses in previous studies, there are few reports applied to pediatric intensive care patients in Korea. To evaluate the effectiveness of the PRISM III score as a severity index for expecting mortality and find important variables influencing mortality, we applied this scoring scale to pediatric neurologic patients admitted to the ICU and analyzed the data statistically. METHODS: Data collection was done by careful review of medical records and scored each clinical variable. The outcome at discharge was determined as non-survival, survival, and hopeless discharge. Determination of mortality in the hopeless discharge group was done within 48 hours after discharge by telephone interview. The study populations were classified into four groups; CNS infection(26 patients), acute encephalopathy(31 patients), status epilepticus(35 patients) and cerebrovascular disorder(4 patients). The difference of the PRISM III score between the survival group and non-survival group was compared by using the nonparametric Mann~Whitney test in the entire study population and for each diagnostic group. To confirm the degree of fitness between the actual mortality and Predicted mortality, the Hosmer-Lemeshow goodness-of-fit test, a multiple logistic regression model was used. All clinical variables used for scoring were compared for survivals and non-survivals by the Chi-square test. f values <0.05 were considered significant. RESULTS: The PRISM III score was significantly higher in the non-survival groups than in the survival group. Predicted mortality from the PRISM III score has fitted to actual mortality According to the results of analyses in each diagnostic groups, the PRISM III score was higher in non-survivals of the acute encephalopathy and CNS infection groups, but statistically insignificant in the cerebrovascular disorders and status epilepticus groups. The important variables of the PRISM III score associated with mortality were mental state, Pupil reflex, systolic blood pressure, acidosis, blood sodium level blood creatinine level, blood glucose level, and PT/PTT. , CONCLUSION: The PRISM III score is helpful in predicting mortality in pediatric intensive care neurologic patients, especially those in the acute encephalopathy or the CNS infection groups. However, this score was not useful in the status epilepticus group, and insignificant in cerebrovascular group. Due to the smallness of the study group, more massive and comprehensive studies are needed as a follow up to this study.

10.Current Issues on Irritable Bowel Syndrome: Diet and Irritable Bowel Syndrome.
Jeong Hwan KIM ; In Kyung SUNG
The Korean Journal of Gastroenterology 2014;64(3):142-147
Irritable bowel syndrome (IBS) is one of the most prevalent functional gastrointestinal disorders. It is a multifactorial disorder with its pathogenesis attributed to abnormal gastrointestinal motility, low-grade inflammation, visceral hypersensitivity, communication in the gut-brain axis, and so on. Traditionally, IBS has been treated with diet and lifestyle modification, fiber supplementation, psychological therapy, and pharmacological treatment. Carbohydrates are intermingled with a wide range of regularly consumed food including grains such as rye and wheat, vegetables, fruits, and legumes. Short-chain carbohydrates that are poorly absorbed exert osmotic effects in the intestinal lumen increasing its water volume, and are rapidly fermented by bacteria with consequent gas production. These effects may be the basis for the induction of most of the gastrointestinal symptoms. This has led to the use of lactose-free diets in those with lactose intolerance and of fructose-reduced diets for fructose malabsorption. As all poorly absorbed short-chain carbohydrates have similar and additive effects in the intestine, a concept has been developed to regard them collectively as FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides and polyols) and to evaluate a dietary approach that restricts them all. Based on the observational and comparative studies, and randomized-controlled trials, FODMAPs have been shown to trigger gastrointestinal symptoms in patients with IBS. Food choice via the low FODMAPs and potentially other dietary strategies is now a realistic and efficacious therapeutic approach for managing symptoms of IBS.
