BACKGROUND/AIMS: Colorectal cancer, one of the most common cancers in developed countries, is curable when diagnosed at an early stage. However, for better screening, both a test that patients will tolerate and diagnostic accuracy are required. We compared patient experiences and preferences between computed tomographic (CT) colonography and conventional colonoscopy (CC) under conscious sedation. METHODS: Patients referred to the gastrointestinal clinic for CC were enrolled to also undergo CT colonography prior to CC. After each procedure, patients completed a questionnaire in which variables, such as abdominal pain, abdominal discomfort, and loss of dignity, were assessed using a 7-point Likert scale, with the highest score representing the worst experience. To verify response stability, a telephone questionnaire followed within 24 h after each procedure. Patients were then asked about their preference for CT colonography or CC. RESULTS: Data were collected from 51 patients who fulfilled all requirements, including CT colonography, CC, the two questionnaires after each procedure, and a follow-up questionnaire. Severity of abdominal pain, abdominal discomfort, and a loss of dignity were reported to be higher in CT colonography than in CC (p<0.01). In addition, the preference for CC was significantly higher than that for CT colonography (p<0.01). CONCLUSIONS: Although CT colonography is a safe and noninvasive screening test for colorectal cancer, further study is required to increase patient acceptance.

OBJECTIVE: The purposes of this study were the development and assessment of an animal model of persistent muscle pain induced by repeated intramuscular injections of low pH buffered saline. METHOD: Buffered saline at pH 4, 6 or 7.2 were injected twice, 3 days apart, into the gastrocnemius muscles of thirty Sprague-Dawley rats. To quantify hyperalgesia, paw withdrawal response to von Frey filament (mechanical hyperalgesia) and acetone (cold hyperalgesia) were measured for the 4 weeks after injection. Also the locomotor performance with inclined plane board and treadmill, and electrophysiologic study were evaluated. RESULTS: Mechanical hyperalgesia that was produced by the single injection of saline lasted less than 24 hours. The repeated injection of acidic saline produced mechanical hyperalgesia for more than 4 weeks at injected side and 3 weeks at contralateral side. Cold hyperalgesia lasted for 1 week after injection bilaterally. The locomotor performance and nerve conduction studies were not changed after injection. CONCLUSION: We have developed and characterized a model of muscular pain that was long lasting and widespread. This might prove useful for studying pain of muscular origin that may be similar to the chronic pain syndromes observed clinically.

Hemobilia is a cause of obscure gastrointestinal hemorrhage. Most cases have an iatrogenic or traumatic origin but cases of hemobilia with non-traumatic causes are rare. The non-traumatic causes of hemobilia are inflammation, gallstones, neoplasm and vascular lesions. Currently, various therapeutic options are available for hemobilia, and transarterial embolization is now the first line of intervention used to stop the bleeding of hemobilia, which shows a high success rate of approximately 80% to 100% with a lower morbidity and mortality rate than with surgery. We report a rare case of non-traumatic hemobilia caused by a pseudoaneurysm of the hepatic artery that was successfully treated with transarterial embolization.

PURPOSE: S. pneumoniae is one of major pathogens of community-acquired respiratory infections. The rate of antibiotic resistance to this organism has increased, and resistance to multiple antimicrobial agents in a single strain of S. pneumoniae may compromise the efficacy of empiric antimicrobial treatment commonly used for respiratory infections. We did this study to find out the penicillin resistant distributions and oral antibiotics susceptibility patterns against S. pneumoniae, isolated from pediatric patients with community-acquired respiratory infections in Korea. METHODS: One hundred fifty six pneumococcal isolates obtained from pediatric patients with community-acquired respiratory infections such as acute otitis media(AOM), sinusitis and pneumonia between May 2000 to June 2003. And MICs of penicillin and oral antibiotics(amoxicillin, amoxicillin- clavulanate, cefaclor) were performed by broth microdilution methods according to the NCCLS(2003a). RESULTS: Seventy eight percent of the isolates were resistant to penicillin. The isolates, collected from AOM patients showed the highest penicillin resistance(92.7%). The resistant rates of amoxicillin (16.7%) and amoxicillin-clavulanate(9.6%), based on susceptibility breakpoints established by the NCCLS, were markedly lower than these of penicillin. But, the resistant rate of cefaclor was very high, above 95%. CONCLUSION: We concluded that pneumococci isolated from study cases may be one of the world's highest penicillin resistant rates. But, amoxicillin and amoxicillin-clavulanate can be used as a first- line antibiotics. Finally, we hope that a continuous surveillance study to monitor resistant patterns of pneumococcal respiratory infections will be needed for the standard guidelines of empiric antibiotic treatment.

PURPOSE: To determine the therapeutic effect of transcatheter embolization in the treatment of splanchnicpseudoaneurysm. MATERIALS AND METHODS: This study involved eleven patients who underwent embolization for thetreatment of splanchnic pseudoaneurysm. Nine were men and two were women ; their ages ranged from 8 to 74 (mean,51) years. The etiology of these cases included postoperative pseudoaneurysm(n=4), pancreatitis(n=3), stabinjury(n=1), and suspected infection(n=1), while two cases were uncertain. The locations of the pseudoaneurysmwere the splenic artery(n=4), the gastroduodenal artery(n=3), the hepatic artery(n=2), the celiac artery(n=1), andboth the right renal and lumbar artery(n=1). All patients underwent angiography prior to embolization. Thematerials used during embolization were a microcoil, a 5-cm metallic guide wire, and a detachable balloon. RESULTS: Embolization was successful in all eleven cases. Among nine cases in which follow-up was possible, angiographywas performed in four, and five cases of thrombus were confirmed by abdominal CT. Three of these nine patientsunderwent re-embolization. One patient underwent elective surgery for a pseudocyst due to pancreatitis. CONCLUSION: Transcatheter embolization is a safe and convenient modality for the treatment of splanchnic pseudoaneurysm.

The prognosis of patients with malignant brain tumors has improved only slightly despite the combined use of surgery, radiation therapy, and chemotherapy. Immunotherapy offers some possibilities and hopes as a fourth modality for the treatment of cancers although it is still in the early stages of development. It is possible to classify immunotherapy within four generally accepted modalities : 1) restorative or nonspecific immunotherapy 2) adoptive immunotherapy 3) passive immunotherapy 4) active immunotherapy. The techniques of recombinant DNA, genetic engineering, cell fusion and hybridoma production, and molecular biology will make these therapeutic approaches more successful and as the clinical applications expand the skillful cancertherapist will become increasingly familiar with these treatments and the problems associated with their use.
