BACKGROUND: Peripheral T cell lymphoma (PTCL), a prevalent form of non Hodgkin lymphomas in East Asia, can manifest fever, hepatomegaly, lymphadenopathy, pancytopenia and hemophagocytic histiocytosis (HPH). Similar clinicopathologic findings are also frequently encountered in reactive hemophagocytic syndrome (HPS) and malignant histiocytosis (MH) , thus diagnoses could be confused among them. With recent advancement of immunohistochemlal techniques, diagnostic accuracies have been improved and most cases of MH could have been reclassified as PTCL. In this study, we intended to delineate the lineage of atypical malignant cells in bone marrow of subjects which were previously diagnosed as MH or HPS with immunohlstochemical analysis and characterize clinlcophathologic findings of PTCL associated with HPH in the bone marrow. METHODS: Five cases dignosed as HPS, 3 as MH, 3 as presumed MH, and 7 as PTCL on bone marrow examination were enrolled in this study. We performed immunohistochemical stain for CD45, CD3, CD43, CD2O and CD68, then revised the diagnoses and summarized the clinical and morphologic features of PTCL associated with HPH. RESULTS: Eleven out of 18 cases were confirmed as PTCL which were previously diagnosed as MH(1), presumed MH(3) and PTCL(7). Eight cases of 11 PTCL showed HPH mimicking MH with infiltration of the atypical malignant cells, even if the proportion of atypical malignant cells was small on bone marrow aspirates. They manifested fever and hepatomegaly but didn't have lymphadenopathy at the early stage of disease. Subtypes of PTCL with HPH were PTCL, unspecifed (3), angioimmunoblastic T cell lymphoma (1) and undetermined (4). They showed poorer outcome in 3-month survival rate (25%) than in those with PTCL without HPH(100%). CONCLUSION: These results suggest that PTCL associated with HPH should be excluded from MH by immunohistochemical analysis. Considering that prognosis of PTCL with HPH is very poor, accurate and rapid diagnosis is needed for prompt treatment.

The incidence of adenocarcinoma of the uterine cervix had shown an increasing tendency, and which is related to the increased use of oral contraceptives or prevalent in human papillomavirus infection. Endocervical glandular dysplasia or adenocarcinoma in situ are occasionally associated with squamous neoplasms of the uterine cervix. This study was aimed to evaluate the histologic features and the incidence of endocervical glandular lesions associated with squamous neoplasms, the presence of human papillomavirus infection-suggesting histologic findings in adjacent squamous neoplasms and the immmunohistochemical findings of endocervical glandular lesions for carcinoembryonic antigen. The materials used were 105 cases of microinvasive and invasive squamous cell carcinoma, and 83 cases of squamous intraepithelial lesions which are consisted of 142 radical or total hystrectomy products and 46 conization or loop excision products. The results are as follows; 1. Among 188 cases, six cases(3.2%) had shown foci of high grade glandular dyaplasia, and 19 cases(10.1%) revealed the areas of low grade glandular dysplasia. There was no adenocarcinoma in situ case. 2. In four of six high grade glandular dysplasia cases, microinvasive or invasive squamous cell carcinomas were associated. In low grade glandular dysplasias, sqaumous intraepithelial lesions were occcupying 68.4%. 3. HPV infection-suggesting histologic findings had accompanied all high grade glandular dysplasia cases and in 17 cases(89.5%) of 19 low grade glandular dysplasias. 4. In 2 of 5 high grade glandular dysplasias and in 1 of 19 low grade glandular dysplasias, the immunohistochemical reaction for carcinoembryonic antigen was similar to that of adenocarcinoma. In conclusion, the clinicopathologic importance of endocervical glandular lesions associated with squamous neoplasms of the uterine cervix should be kept in mind, and further study for the relationship between endocervical glandular lesions and human papillomavirus infection or hormonal influence will be continued.

Primary sclerosing cholangitis is a chronic disease of unknown cause, characterized by inflammation and fibrosis of the biliary tree with diffuse multifocal stricture formation. With increasing knowledge of primary sclerosing cholangitis, it is now recognized that in the setting of inflammatory bowel disease, cholangiocarcinoma is a complication of primary sclerosing cholangitis. We recently experienced a case of 41 year old female patient who had Crohns disease associated with primary sclerosing cholangitis and cholangioearcinoma. We report a case of primary sclerosing cholangitis with cholangiocarcinoma with literature review.

Internal hernia is an unusual cause of the intestinal obstruction. The advances of CT make the diagnosis more easier than in the past. We report one case of internal hernia with herniation of the ileum into the lesser omenturn. The diagnosis could be made when abdominal radiographs showed fixed clustering of the small bowel loops in upper abdomen medial to the stomach. CT and ultrasound showed characteristic interposition of the ileum between the left hepatic lobe and the stomach.

Juvenile dermatomyositis is an uncommon autoimmune disease with classic heliotrope discoloration of eyelids, erythematous skin rash of joints and proximal muscle weakness. Quite different from adults, malignancy is rarely accompanied in juvenile dermatomyositis. However vasculitis, muscle atrophy, calcification and gastrointestinal involvement are often observed in juvenile dermatomyositis. A six year old boy was admitted with chief complaints of general weakness and skin rash. Muscle biopsy was performed which was consistent with dermatomyositis. The patient was treated with intravenous immunoglobulin, steroid, methotrexate and physiotherapy. We report a case of juvenile dermatomyositis.

BACKGROUND: Cardiovascular disease is the major cause of morbidity and mortality. It is well known that androgen and sex hormone-binding globulin(SHBG) in women were associated with risk factors for cardiovascular disease such as obesity, central fat accumulation and atherogenic lipid profile. High resolution B-mode ultrasonography can visualize directly both luminal and vessel wall characteristics, and ultrasonic measurement of carotid intima-medial thickness(IMT) can be used to investigate the atherosclerosis of coronary, cerebral and peripheral arteries. The aim of this study was to evaluate the relationship between the serum dehydroepiandrosterone sulfate(DHEA-S) and SHBG, and body fat distribution pattern, cardiovascular risk factor and carotid atherosclerosis in women. METHODS: Blood pressure, fasting serum glucose, insulin, lipid profile, SHBG and DHEA-S were measured. Body fat distribution pattern was assessed by waist to hip ratio, waist to thigh ratio and subscapular to triceps skin fold thickness ratio, faf mass measured by bioelectric impedance analyzer, subcutaneous fat area, visceral fat area, and visceral to subcutaneous fat area ratio(VSR) at the level of umbilicus using the computed tomography. The IMT of the carotid artery was measured by high resolution B mode ultrasound as a marker of atherosclerosis. RESULTS: 1) There was no significant difference of age-adjusted values of carotid IMT among subjects with NGT(0.426+/-0.09mm), IGT(0.46+/-10.09mm) and NIDDM(0.453+/-0.11mm). 2) In postrnenopausal women, carotid IMT was greater(0.484+/-0.11mm, p=0.05) than premenopausal women(0.426+/-0.08mm), but it was not significant after age adjustment. Serum SHBG and DHEA-S levels in postmenopausal women were significantly lower(p<0.05) than premenopausal women, but they were not significant after age adjustment. 3) Carotid IMT was significantly correlated with age(r=0.37, p<0.01), fasting serum glucose (r=0.32, p<0.01), total cholesterol(r= 0.25, p<0.05), LDL-cholesterol(r=0.26, p<0.05), visceral fat area(r=0.35, p<0.01) and VSR(r=0.31, p<0.05). 4) By the stepwise multiple regression analysis, carotid IMT was positively and significantly associated with age(p<0.01) and serum DHEA-S concentration(p<0.05) in dent of age, body mass index, waist to hip ratio, fasting serum glucose. CONCLUSION: Carotid IMT was associated with age and serum DHEA-S concentration in women without cardiovascular disease. Therefore, serum DHEA-S may be one of risk factors for cardiovascular disease in women. However, we could not conclude its cause-result relationship because of cross sectional nature of our study, and prospective study will be needed.

PURPOSE: The aim of this study was to determine the prevalence of asymptomatic nasopharyngeal carriages in children using a multiplex reverse transcriptase-polymerase chain reaction (mRT-PCR) assay kit. METHODS: We obtained nasopharyngeal swabs from 33 children without any underlying disease from July 25 to July 28, 2008. The children were free from the signs of respiratory tract infections at the time of sampling. DNA was extracted from the swabs and subjected to multiplex RT-PCR using a primer set for the detection of pneumococci (Seeplex(R) PneumoBacter ACE Detection Seegene, Seoul, Korea). The amplified PCR products were separated on 2% agarose gels and stained with either ethidium bromide or screen tape system (Lab901 Scotland, UK). RESULTS: A total of 33 children (male, 15 female, 18) aged between 3.2 and 16.3 (median, 8.2) years were included in this study. The mRT-PCR detected colonized bacteria (Streptococcus pneumoniae, Hemophilus influenzae, Chlamydia pneumoniae, and Bordetella pertussis) in 30 children (90.9%). Of these, 13 children (39.4%) showed more than 2 bacteria: 12 children were positive for 2 bacteria (S. pneumoniae and H. influenzae) and 1 child was positive for 3 bacteria (S. pneumoniae, H. influenzae, and C. pneumoniae). CONCLUSION: mRT-PCR was found to be a sensitive tool for the detection of asymptomatic nasopharyngeal carriages. Clinical significances of the bacteria detected by mRT-PCR will have to be evaluated in the future.

BACKGROUND: Etanercept is a recombinant human soluble tumor necrosis factor-alpha (TNF-alpha) receptor fusion protein that inhibits TNF-alpha, a major mediator in the pathogenesis of graft-versus-host disease (GVHD). The purpose of our study was to evaluate the safety and efficacy of etanercept therapy in children with steroid-refractory acute GVHD (aGVHD) (n=5) and chronic GVHD (cGVHD) (n=3). METHODS: Five males and 3 females were enrolled and their median age was 14.4 years (range, 2.1~18.8). Etanercept 0.4 mg/kg per dose (maximum dose, 25 mg) was given subcutaneously twice weekly for 4 weeks followed by 0.4 mg/kg per dose (maximum dose, 25 mg) weekly for 4 weeks. At the time of initiation of etanercept, 5 patients had aGVHD grade III to IV (III=4, IV=1) and 3 patients had moderate to severe cGVHD (moderate=1, severe=2). RESULTS: Overall, 6 of 8 patients (75%) responded to the treatment with etanercept, including 5 patients with aGVHD [n=3 complete response (CR), n=2 partial response (PR)] and 1 patient with cGVHD [n=1 PR, n=2 no response (NR)]. Clinical responses were most commonly seen in patients with refractory gut aGVHD. CMV reactivation occurred in 2 patients, bacterial infection in 1 patient, and fungal infection in 1 patient. CONCLUSION: Our preliminary data indicate that etanercept is well tolerated and can induce a high response rate in patients with steroid refractory aGVHD, particularly in the setting of intestinal involvement.

BACKGROUND/AIMS: Because treatment duration directly influences both patient compliance and side effects in the eradication of Helicobacter pylori (H. pylori), shortening the duration remains the main goal of therapeutic strategies. The aim of the present study was to evaluate the efficacy and safety of short-term regimen (weekend therapy) for curing the H. pylori infection. METHODS: Twenty-eight patients with H. pylori-positive peptic ulcer received omeprazole 40 mg once daily for 7 days (from Monday to Sunday), bismuth 240 mg q.i.d., amoxicillin 1 g q.i.d., and metronidazole 500 mg q.i.d. for only 2 days (Saturday and Sunday). We compared the eradication rate with that of seventy-eight patients with H. pylori-positive peptic ulcer who had received either OAC (omeprazole, amoxicillin, and clarithromycin) or BMA (bismuth, metronidazole, and amoxicillin) regimens during the same period. H. pylori infection was assessed before treatment by rapid urease test or histologic examination. Four weeks after the end of treatment, the infection was also assessed by rapid urease test, histologic examination or urea breath test in weekend group and by urea breath test in control group. RESULTS: H. pylori eradication rates were 61.1% by per-protocol analysis and 39.3% by intention-to-treatment analysis. There were no treatment associated serious side effects, and only one patient (5.6%) showed mild epigastric discomfort. All patients completed the course of treatment. CONCLUSIONS: Weekend therapy have relatively low eradication rate, however, this therapeutic approach is safe and shows good compliance for the treatment of H. pylori infection.
