PURPOSE: Kimura's disease is an uncommon benign lymphoproliferative inflammatory disorder with an unknown etiology. The recurrence rate after surgical excision is relatively high and renal involvement is its only systemic manifestation. The condition mainly involves the head and neck, and peripheral involvement is extremely rare. MATERIALS AND METHODS: We encountered the case of a 28-year-old man who had a non-tender mass with mild brownish skin color changes and pruritus around the medial side of the distal arm and elbow. RESULTS: The peripheral blood investigation revealed peripheral eosinophilia and elevated serum IgE levels. Magnetic resonance imaging showed an isointensity signal relative to the muscle on the T1-weighted images and hyperintensity signal relative to the muscle on the T2-weighted images. CONCLUSION: A marginal resection of the lesion was performed and there was no recurrence at 2 years postoperatively.

BACKGROUND: An essential prerequisite for successful procurement of sufficient peripheral blood stem cells (PBSC) for engraftment is the optimal timing of collection. The Sysmex SE-9000 automated hematology analyzer provides the immature information (IMI) channel for the identification and counting PBSC. In this study, The optimal timing of PBSC collection was studied using IMI channel. METHODS: 193 peripheral blood stem cell collections were performed from 52 patients with hematologic disorders or solid tumors and 15 donors. Pre-harvest peripheral blood WBC, mononuclear cells (MNC) and IMI were tested and compared with CD34+ cell count and CFU-GM count of harvested products. RESULTS: Peripheral blood WBC and MNC count showed a weak correlation with CD34+ cell yield (r=0.38, P<0.0001 and r=0.38, P<0.0001) and peripheral blood IMI had a stronger correlation (r=0.58, P<0.0001) with collected CD34+cells than did WBC and MNC count. A receiver operating characteristic (ROC) curve was drawn for cutoff value of IMI and predictive values of the chosen cutoff value of IMI for different target CD34+ cell collections were calculated. The ROC curve showed that the best cutoff value of IMI was 465/microliter for the target CD34+ cells >1x10(6)/kg with sensitivity of 88.7%. Positive and negative predictive values of IMI >465/microliter for CD34+ cell >1x10(6)/kg were 65.5% and 87.5%, respectively. CONCLUSIONS: The automated IMI might be used as a simple and efficient indicator of PBSC mobilization and applying variable cutoff values of IMI would be a useful tool to predict the optimal timing of PBSC collection.

Cronkhite-Cadana syndrome is a rare non-familial disease. This syndrome is characterized by multiple hamartomatous polyps on the entire gastrointestinal tract except esophagus, nail dystrophy, alopecia and hyperpigmentation. Taste disturbance, abdominal pain, diarrhea and weight loss are common symptoms of it. The pathogenesis and causes of Cronkhite-Canada syndrome remain unknown until now. Although various treatment strategies including steroid therapy have been tried, their prognosis is poor. We report a 68 years old man who were diagnosed Cronkhite-Canada syndrome with esophageal candidiasis. After using combination of steroids and anti-fungal drugs, both Cronkhite-Canada syndrome and esophageal candidiasis were cured.

BACKGROUND/AIMS: Nonalcoholic steatohepatitis can develop from nonalcoholic fatty liver and progress to severe liver disease such as cirrhosis. The mechanism determining the progression from fatty liver to steatohepatitis is unknown. Iron is suspected to enhance hepatic damage associated with nonalcoholic fatty liver disease (NAFLD). The aims of this study were to evaluate the relationship of serum iron indices and hepatic iron deposition with hepatic fibrosis or inflammation, and to assess whether the increased hepatic iron deposition is an independent predictor of progression to liver injury. METHODS: The biochemical and histopathological data of thirty-nine patients with NAFLD were analyzed. Liver biopsy findings were graded according to the method described by Brunt, et al. Hepatic iron concentration was available in 29 of 39 patients. RESULTS: The mean hepatic iron concentration and hepatic iron indices were 1,349+/-1,188 microgram/g dry weight and 0.9+/-0.7 microgram/g/age. Serum ferritin and body mass indices were associated with hepatic inflammation (p=0.001, p=0.006) and fibrosis (p=0.005, p=0.013). Hepatic iron concentration and hepatic iron index were not associated with hepatic inflammation and fibrosis. Multivariate analysis did not identify serum ferritin or body mass index as an independent predictor of liver injury. CONCLUSIONS: Hepatic iron deposition shows no association with the degree of hepatic inflammation or fibrosis. Hepatic iron is not an independent predictor of hepatic injury in patients with NAFLD.

BACKGROUND: Tuberculosis is more prevalent in dialysis patients than in the general population, and more difficult to make a diagnosis, and often leads to death, Moreover, extra-caution is needed in prescribing anti-tuberculosis medications as dose modification is frequently needed in patients with renal insufficiency. Several pharmacokinetic studies have been performed for antimycobacterial regimens in patients with renal insufficiency, including under hemodialysis. However, the anti-mycobacterial regimens of patients on peritoneal dialysis have been made based on empirical methods because of few pharmacokinetic studies. METHODS: To elucidate the pharmacokinetic profiles of anti-mycobacterial regimens for peritoneal dialysis, we measured both plasma and peritosol concentrations of anti- tuberculous drugs including isoniazide, rifampin and pyrazinamide in 9 patients maintained on chronic ambulatory peritoneal dialysis(CAPD). RESULTS: After a conventional oral dose of anti-tuberculosis medication, their plasma concentrations were in the therapeutic range, but the peritosol concentration of rifampin was below the therapeutic range. CONCLUSION: No dose adjustments are required for isoniazid, rifampin and pyrazinamide for the treatment of systemic or peritoneal tuberculosis in CAPD patients. On the contrary, oral rifampin is not expected to be effective in the treatment of tuberculous peritonitis, because of its low peritosol concentration.

BACKGROUND: Clinical trials that utilize imaging findings as surrogate endpoints are considered to be cost-effective. However, unlike numeric data, magnetic resonance imaging (MRI) findings are not quantifiable. Thus, we have begun to develop a software package that is able to convert qualitative MRI findings into quantifiable data. METHODS: Computer software (DUIH_Image) was created with which every patient's MRI data can be registered on a standard brain template. Interuser and intrauser reliabilities for the registration were measured, and then a proof-of-principle experiment was conducted to determine whether the system could identify factors that were associated with a greater National Institutes of Health Stroke Scale (NIHSS) score at admission. We studied 40 consecutive patients [65.1+/-14.2 years old (mean+/-SD); 22 males and 18 females] with first-ever acute lacunar infarction of the corona radiata, who were divided into two groups according to their NIHSS score (i.e., low: 0-2; high: > or =3). The following parameters were compared between these two groups: (1) data retrieved from clinical profiles, including demographic and risk factor variables; and (2) accumulated diffusion MRI lesions mapped on a standard template. RESULTS: Modest levels of interuser and intrauser reliability were observed (p<0.05, R(2)=0.63-0.84, Pearson correlations). Regarding the clinical profiles, no significant difference was found for the numeric data sets or infarct size between the two groups. However, on the accumulated lesion map image, the lesion area that overlapped the most was located more posterolaterally in the high NIHSS score group than in the low NIHSS score group. CONCLUSIONS: In this pilot study we have demonstrated the potential usefulness of the DUIH_Image software. We plan to update this software to enable its utilization in actual clinical trials.
