OBJECTIVE: To investigate whether the serum levels of IL-10 in patients with rheumatoid arthritis are different from those of normal controls and SLE patients and to find out any correlation with disease activity parameters of rheumatoid arthritis. METHODS: Sera from 20 healthy normal persons, 16 rheumatoid arthritis patients and 16 patients with systemic lupus erythematosus were collected and measured for IL-10 and IL-6. Various disease activity parameters were measured in RA patients. RESULTS: The serum level of IL-10 in RA patients was significantly elevated compared to normal controls but lower than those of SLE patients. In RA patients there was no definite correlation between the disease activity parameters and serum IL-10 levels. Despite significant improvements in terms of various disease activity parameters, there was no significant change of serum IL-10 levels after treatment in RA patients. In seropositive RA patients, positive correlation was found between serun IL-10 and rheumatoid factor levels. CONCLUSION: Our findings show that the serum IL-10 levels in patietns with RA are elevated compared to normal controls but lower than those of SLE patients. There was no correlation between serum IL-10 levels and disease acivity parameters of RA.

So-called, the double channel pylorus has been, relatively rarely, reported through out the world. All reported cases were almostly those of gastroduodenal fistula as a complication of peptic ulcer disease. The congenital forms of double pylorus were reported even more rarely. We found three cases of double channel pylorus in 25,000 cases endoscopy done at our unit. All those three cases were thought to be acqired form endoscopically, radiographically and histologically. One of those was undergone to operative resection because of uncontrollable bleeding and the others were on medical theraphy with satisfaction.

Distal myopathy with rimmed vacuoles is a rare muscle disease and, so far as we know, it has not been reported in Korea as yet. This disorder is known to be inherited as autosomal recessive trait and to have no specific treatment. Hereby, we report 3 patients of distal myopathy with rimmed vacuoles in a family. The clinical characteristics of these patients were slowly progressive symmetrical muscle weakness and wasting of all 4 extremities, worse in distal legs. The pretibial muscles were involved more markedly than the calf muscles. Serum muscle enzymes were increased. The prominent EMG findings were myopathic changes, but reduced recruitment was occasionally found in some distal muscles The muscle biopsies of right biceps brachii muscle were performed in two patients, which showed the characteristic rimmed vacuoles by light microscope. Membranous whorls and randomly oriented intracytoplasmic filaments were found by electron microscope. The severity of pathological abnormalities were related to the clinical status of the patient. One had been treated with steroid(prednisolone) for several years but with no improvement.

OBJECTIVES: Visualization of the left atrial appendage(LAA) by the transesophageal echocardiography(TEE) is excellent, but it is difficult to visualize the LAA by the modified parasternal short-axis view(MPSA) in transthoracic echocardiography(TTE). We studied to determine the usefulness of the apical horizontal view(AHV) abtained by the apical rotation method of the transducer for the detection of the LAA. METHODS: We studied the MPSA and AHV in 602 patients, The LAA was observed during diastole of the LAA. We obtained an apical horizontal view by 45 degree clockwise rotation of the transducer from the apical 2 chamber view and compared with the visualization of the LAA in AHV and MPSA. RESULTS: Among 602 patients, LAA could not be visualized in 88(14.6%) because of a poor echo-window. LAA was more clearly visualized in 222 patients by the AHV than the MPSA and 56 patients by the MPSA than the AHV. LAA was same degree visualization in patients by the AHV and MPSA. In male and female, more than 55 ages and less than 55 ages, visualization of inner margin of the LAA by the AHV was more clear than by the MPSA. CONCLUSION: The AHV was a useful, noninvasive and reproducible method for the visualization of the LAA.

Sensory neuropathy is characterized by pure sensory dysfunction, ultimately evolving into areflexia and severe sensory ataxia in spite of the preservation of the other functions in the nervous system such as motor function. This disorder is known to be commonly found in cancer patients as a paraneoplastic syndrome, but nowadays many reports are made that sensory neuropathy is not merely related to malignancy but also with autoimmune disorders such as Sjogren's syndrome or polyclonal gammopathy, etc. Hence we report two patients who have been diagnosed as chronic idiopathic ataxic sensory neuropathy through electrophysiological and histopathological studies without any evidence of cancer or any other known cause.

In 17 myotonic cases (16 of myotonic muscular dystrophy and 1 of congenital myotonia), 13 cases showed significant decremental responses on RNS study. The decremental responses had the tendency of more prominence on faster stimulating rate, and in the proximal limb muscles. This result suggests that the RNS test is useful but not specific for the disorder of neuromuscular junction.

BACKGROUND: It has long been suggested that neutrophils and their products are implicated as the central mediators of the acute lung injuries. Contrary to the dominant role of neutrophils in ARDS, many cases of ARDS has occurred in the setting of severe neutropenia without pufrnonary neutrophil infiltration. Therefore it is certain that effector cell(s) other than neutrophil play an important role in the pathogenesis of ARDS. This experiment was performed to define the mechanism of ARDS in the setting of neutiopenia, 1) by comparing the severity of endotoxin-induced lung injury, 2) by measurement of hydrogen peroxide production and cytokine concentration in the bronchoalveolar lavage cells and fluids obtained from different rats with and without cyclophosphamide-pretreatment. METHOD: The male Sprague-Dawleys were divided into the normal control (NC)-, endotoxin (ETX)-, and cyclophosphamide (CPA)-group in which neutropenia was induced by injecting cyclophosphamide intraperitoneally. Acute lung injury was evoked by injecting lipopolysaccharide (LPS) into a tail vein. The bronchoalveolar lavage (BAL) was performed at 3 and 6 hour after administration of LPS to measure the change of cell counts and concentrations of protein and cytokines, tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6). Hydrogen peroxide (HPO) production from BAL cel]s was measured at 6 hour after LPS administration by phenol red microassay with and without zymosan stimulation. RESULTS: The results were as follows. A change of leukocyte counts in the peripheral blood after treatment with CPA More than 95% of total leukocytes and neutrophils were reduced after CPA administration, resulting in severe neutropenia. A change of BAL cells In the ETX-group, the number of total cells (p<0.01) and of macrophage and neutrophll (p<0.05) were increased at 3 and 6 hour after LPS administration compared to those of NC- group. In the CPA-group, the number of total leukocyte and macrophage were not changed after LPS administration, but neutrophil counts were significantly reduced and jt took part in less than 0.1% of total BAL cells (p<0.01 vs NC-group). BAL cells in this group were almost all macrophages (99.7%). A change of protein concentration in the BALF In the ETX-group, protein concentration was increased at 3 hour and was more increased at 6 hour after LPS administration (p<0.05 and <0.01 vs NC-group, respectively). In the CPA-group, it was also significantly elevated at 3 hour after LPS administration (p<0.05 vs NC-group) , but the value was statistically not different from that of ETh-group. The value measured at 6 hour after LPS administration in the CPA-group became lower than that of ETX-group (p<0.05), but showed still a higher value compared to that of NC-group (p<0.05). A change of cytokine concentration in the BALF TNF-alpha and IL-6 were elevated in the ETX- and CPA-group compared to those of NC-group at both time intervals. There was no statistical difference in the values of both cytokines between the ETX- and CPA-groups. Measurement of hydrogen peroxide production from BAL cells There was no intergroup difference of HPO production from resting cells. HPO production after incubation with opsonized zymosan was significantly elevated in all groups. The percent increment of HPO production was highest in the ETX-group (89.0%, p<0.0008 vs NC-group ), and was 42.85 in the CPA-group (p = 0.003 vs NC-group ). Conclusion Acute lung injury in the setting of neutropenia might be caused by functional activation of resident alveola r macrophages.

Although bizarre parosteal osteochondromatous proliferation does not frequently occur, this calcified, osteal, chondromatous tumor has relatively high recurrence rates and presents clinical, radiological, histological features that can be classified with other lesions. And it is a benign disease that until now, there were no death or metastasis reports because of this tumor. This proliferation is hard to distinguish between other benign tumors and non-neoplastic lesions if it is occurred in small bone of hand or foot. We experienced bizarre parosteal osteochondromatous proliferation of middle phalanx of the little finger, and report this case and the review of relevant literature.

Tuberculous colitis, an important extra-pulmonary tuberculosis, is still prevalent in the developing countries and has been resurging in the Western world. The duration and dose of anti-tuberculous therapy have not yet been clarified in the tuberculous colitis. We experienced a case of tuberculous colitis, which relapsed after 9 months of therapy. A 28-year-old man presented with hematochezia and was diagnosed as tuberculous colitis on the basis of colonoscopic findings. He was treated with anti-tuberculous agents for 9 months successfully. Three months later, however, he complained of hematochezia again, suggesting the relapse of tuberculous colitis. He had taken anti-tuberculous therapy for another 15 months and showed no evidence of relapse. Although anti-tuberculous therapy is efficient for tuberculous colitis, rare cases of reactivation should be reminded.

To assess the effect of postoperative radiotherapy on tumor recurrence and patient survival, 133 patients who received adjuvant postoperative radiotherapy for adenocarcinoma of the rectum were retrospectively analyzed. Sixty-one percent of the patients were in stage C2 by Astler-Coller staging system. A significant statistical difference was noticed in failure rates for lymph node negative vs lymph node positive patients;26%(9/35) vs 50%(49/98). The incidence of local failure was found to be strongly dependent on the pathologic stages; with 9%(3/35) of recurrence in stage B and 21% (21-98) in stage C. Distant metastasis has occurred in 29% (38/133) of the patients; 2% (7/35) in stage B and 32%(31-98) in stage C. The actuarial Survival at 3 years for patients in stage B2, stage C1, and stage C2, were 78%, 47%, and 38%, respectively. In conclusion, the postoperative adjuvant radiotherapy for rectal carcinoma appears to reduce local recurrence significantly.
