PURPOSE: The accuracy of CT in the detection of injuries of the solid visceral organ is well established, but the value of CT in diagnosing small bowel rupture after abdominal trauma is controversal. This study was conducted to ascertain CT finding of small bowel rupture result from abdominal trauma. MATERIALS AND METHODS: A retrospective analysis of preoperative abdominal CT findings in 40 patients was performed. Small bowel rupture was confirmed by surgery. Precontrast and postcontrast enhanced CT images were obtained in all patients. RESULTS: Diagnostic findings of small bowel rupture including pneumoperitoneum or retroperitoneal air, discontinuity of the bowel wall and extravasation of oral contrast materials were observed in 33 cases(83%). Intraperitoneal or retroperitoneal free air was seen in 31 cases(78%) and intraperitoneal or retroperitoneal free fluid collection was seen in 38 patients(95%). Small bowel wall was thickened in 31 cases(78%), bowel wall was enhanced in 12 cases(30%) and bowel wall discontinuity and extravasation of oral contrast material was seen in 5 cases, respectively. CONCLUSION: The CT scan is sensitive and effective modality for evaluation of small bowel rupture after abdominal trauma, because of high detectability of diagnostic and suggestive CT findings.

Sensorineural hearing loss (SNHL) that is seldom cited as a Kawasaki disease (KD) complication is known as an additional, potentially severe, and frequently irreversible sequel. Furthermore the vestibular functions of KD have been underestimated and it could be an important complication combined with SNHL in KD. We described a case that a 4 year-old boy who developed vestibular loss with SNHL has recovered successfully with a combined treatment.

Cervical metastasis of squamous cell carcinoma from an unknown primary site occurs in approximately 2–4% of head and neck tumor cases. Without identification of the primary site, proper management cannot be achieved, resulting in significant morbidity and a lower cure rate. For the primary site assessment, positron emission tomography/computed tomography (PET/CT) using the radiotracer 18F-fluorodeoxyglucose (FDG) is the imaging modality of choice and has been shown to be superior to CT alone. Here, we report a case of cervical metastasis of squamous cell carcinoma in an 82-year-old man. 18F-FDG PET/CT revealed a tongue-base lesion, although neck CT detected no lesions because of artifacts from dental prosthesis, which was suspected as the primary site. The final diagnosis was confirmed as tongue-base cancer with neck lymph node metastases through biopsy. These results suggest that 18F-FDG PET/CT is a valuable diagnostic tool in patients with cervical metastatic lymph nodes because it can demonstrate primary tumors in patients with dental prosthesis.

PURPOSE: Chromosome microdissection has become a very powerful approach to generate chromosome band-specific library and painting probes for physical mapping or cytogenetic analysis. We have constructed here band-specific painting probes for human chromosomes by microdissection and polymerase chain reaction(PCR). METHODS: We pretreated the microdissected fragments with Topoisomerase I(Topo I) which catalyzes the relaxation of supercoiled DNA, and performed two initial rounds of DNA synthesis with T7 DNA polymerase followed by conventional PCR to enable the reliable preparation of fluorescent in situ hybridization(FISH) probe. RESULTS: It was possible to construct region-specific painting probes for 5q14-q15, 6q23, 16p11.2 and 22q12. The painting probes were successful in determining the corresponding chromosome bands in SNU-484 cell line, IMR-32 cell line. CONCLUSION: These painting probes can be used to detect the related marker chromosomes in congenital malformations and other solid tumors, and the band specific probe pools may be used effectively to analyse the genes.

Diphenylhydantoin (DPH) is one of the most widely used anticonvulsants for treatment and prevention of seizures. However it is frequently associated with drug-induced leukopenia. Hypersensitivity reactions to phenytoin are well recognized and can be severe. Phenytoin is associated with serious hematologic side effects such as agranulocytosis, thrombocytopenia, red cell aplasia and hemolytic anemia, either through humoral or cell-mediated immunemechanism. We describe a 57-year-old male patient who developed a severe granulocytopenia while taking phenytoin for 66 days in the total amount of 21.6 gram. Bone marrow examination showed isolated depletion of myeloid elements. After 10 days of phenytoin withdrawal and G-CSF treatment, the patient recovered from granulocytic suppression. Using in vitro culture, marrow suppression associated with phenytoin therapy was felt to be non-immune mediated marrow suppression.

PURPOSE: Most malignant peritoneal or pleural effusions caused by advanced malignancy are unresponsive to systemic chemotherapy except for chemotherapy sensitive tumors, and they are equally ineffective to regional therapy or radiotherapy. Thus, for the purpose of palliating the symptoms related to malignant effusion and to reduce fluid reaccumulations, we evaluated the therapeutic feasibility and efficacy of intracavitary ' Ho-CHICO (chito- san complex) instillation for intractable malignant effusions. MATERIALS AND METHODS: Thirty one patients with cytologically or pathologically proven malignant effusions underwent intracavitary 166Ho-CHICO therapy from May 1996 to March 1998 at Ajou University Hospital. The subjective and objective responses were evaluated 4 weeks after the treatment, including the changes of symptoms, weight, abdominal girth, doses of diuretics, frequencies and amounts of repeat aspirations for fluid reaccumulations, and imaging studies of chest radiograph and ultrasounds. RESULTS: The response rates treated with Ho-CHICO were 50% in patients with peritoneal effusion and 46% in patients with pleural effusion (overall 49%). The response rates between 166Ho-CHICO doses of 50-80 mCi and 90-100 mCi were similar (50% vs 47%). Response rate of 70% was noted in patients with even distribution of radioisotope on the post-therapy scan, but, the response rate was lower in cases with focal (44%) and uneven (29%) distribution pattern. There was no difference in response by the effusion sites. All patients tolerated intracavitary 166Ho-CHICO instillation well, although the majority of patients experienced Grade I/II side effects such as pain, fever, weakness and dyspnea. But, no serious complications of Grade lII or IV degree were observed with 166Ho-CHICO therapy. CONCLUSION: Intracavitary 166Ho-CHICO instillation was clinically efficacious in controlling malignant effusions without a significant toxicity seen with conventional sclerotic therapy. The therapeutic modality appeared to offer similar benefits obtained with the conventional intracavitary therapy.

BACKGROUND: Macrophages are a component of a tumor's microenvironment and have various roles in tumor progression and metastasis. This study evaluated the relationships between tumor-associated macrophage (TAM) density and clinical outcomes in 14 different types of human cancers. METHODS: We investigated TAM density in human tissue microarray sections from 14 different types of human cancers (n = 266) and normal thyroid, lung, and breast tissues (n = 22). The five-year survival rates of each cancer were obtained from the 2011 Korea Central Cancer Registry. RESULTS: Among 13 human cancers, excluding thyroid cancer, pancreas, lung, and gallbladder cancers had the highest density of CD163-positive macrophages (7.0+/-3.5%, 6.9+/-7.4%, and 6.9 +/- 5.5%, respectively). The five-year relative survival rates of these cancers (pancreas, 8.7%; lung, 20.7%; gallbladder, 27.5%) were lower than those of other cancers. The histological subtypes in thyroid cancer exhibited significantly different CD163-positive macrophages densities (papillary, 1.8 +/- 1.6% vs anaplastic, 22.9 +/- 17.1%; p < .001), but no significant difference between histological subtypes was detected in lung and breast cancers. Moreover, there was no significant difference in CD163-positive macrophages densities among the TNM stages in lung, breast, and thyroid cancers. CONCLUSIONS: Cancers with higher TAM densities (pancreas, lung, anaplastic thyroid, and gallbladder) were associated with poor survival rate.
