Biofeedback is the treatment of choice for functional defecation disorders such as idiopathic chronic constipation and neurogenic fecal incontinence. The pre-existing biofeedback systems have many disadvantages. The aims of current project are, first, to develop the biofeedback system into the application software in the Windows environment, and, second, to assess the possibility of clinical usage for patients with functional defecation disorders. The hardware and software of the BASCO (Biofeedback Anal Sphincter Control) system were based on the signal measurement and signal processing of anal sphincter EMG (Electromyography). BASCO system was applied to 5 normal healthy controls and 20 patients with functional defecation disorders. Patients group was categorized as constipation group (N1=15) and incontinence group (N2=5). With use of current system, EMG-based biofeedback therapy was performed, and the outcome was analysed. Anal EMG signal data was processed by the software, and displayed in the monitor of personal computer. The software of EMG-display and database management were adequately operated. In N1 group, a paradoxical elevation or equalized activity of anal EMG pattern was shown in the simulated defecation. In N2 group, low electrical activity was shown. These findings were used for the EMG-based biofeedback therapy as a pilot study. The clinical symptoms were improved in 12 of N1 group and 3 of N2 group in the period of 3.7 (range, 1~12) months follow-up. In Conclusion, newly-developed BASCO system was adequately operated in the volunteer and patients groups. The multi-tasking and multi-processing functions were adequately shown in the real time. Current results could be used for clinical appraisal. Specifically, this system could be used for the practical application of biofeedback therapy in the patients with chronic constipation or fecal incontinence.

Myotonic dystrophy is a multisystemic disorder inherited as an autosomal dominant trait. The characteristic clinical features include the presence of myotonia, atrophy of the muscles of the face and the sternocleidomastoids and numerous nonmusclar manifestations such as cataracts, frontal baldness, gonadal dysfunctions and cardiac abnormalities. We experienced one case of myotonic dystrophy with prolonged atrial flutter in 30-year-old male who was admitted because of palpitation. We present this case with reviewing literatures.

BACKGROUND: Systemic lupus erythematosus(SLE) frequently has cardiovascular complications. Pericardial inflammation and effusion. ventricular dysfunction, valvular disease and coronary atherosclerosis may result in morbidity. While the pathologic findings in SLE have been well described, the antemortem documentation of the cardiac complications has been less frequent than the postmortem findings would support, we therefore sought to study how echocariography may improve the clinical assessment of cardiac involvement in 40 consecutive patients with SLE. SUBJECTS AND METHODS: This study began in 1990 with a prospective design. An appointment was scheduled with all patients whose SLE was diagnosed at the outpatient clinic and during the admission of the internal medicine service at the Kang Nam St Mary's hospital These were 40 female patients, with a mean age of 32+/-11 years(+/-SD). The average duration of disease was 37+/-32months, the average dosage of prednisolone per day was 20+/-17mg. M-mode and 2-D echocardiogram were carried out to the 40 SLE patients. RESULT: Seventeen(43%) of the SLE patients had pericardial effusion. Reduced left ventricular contractility was evident in 8 patients(20%). Abnormality of diastolic dysfunction to be checked by A/E ratio was in 3 patients(8%). No patients had echocardiographic evidence of pulmonary arterial hypertension. Clinical findings of myocardial dysfunction in these patients included dyspnea(30%), jugular venous distension(20%), rales(10%) and S3 gallop(8%). Valvular abnormality of SLE patients included mitral regurgitation in five patients(13%) and aortic regurgitation in two patients(5%). Electrocardiogram showed myocardial ischemia, atrial fibrillation and sick sinus syndrome in 3, 1 and 1 patients respectively. CONCLUSION: In this study, pericardial effusion were the most common echocardiopraphic abnormalities in Patients with SLE. The incidence of valvular and myocardial disease were relatively common.

To eliminate the inconvenient shortcomings of our formerly designed system for the biofeedback treatment, the development of second stage software was indispensable. PURPOSE: The aims of current study were to supplement the prototype software, and to improve the application software for the database management system. Moreover, we assessed the practical value and outcome of biofeedback therapy for the patients with functional evacuation disorders by using the upgraded system. METHODS: A new system was worked out a design to be composed of Windows based GUI (graphical user interface), DB (database) management software, and networking system. Main software performs a signal processing and a protocol making mode to train pelvic sphincter. DB program administers patient profiles and the recorded signal data. Networking system was designed to execute RS-232C serial communication of signal data with use of fast ethernet LAN networking. To affirm the reproducibility of signal display for the clinical practice, system was applied to 5 healthy volunteers. To evaluate the practical appraisal, system was applied to 27 patients with functional evacuation disorders who were undertaken anorectal physiologic tests. Patient groups were categorized as nonrelaxing puborectalis group (group I, n=17), incontinencegroup (group II, n=10). Overall patients were underwent a mean 3.7 (range, 2~10) sessions of biofeedback treatment, and the outcome was analysed in the period of 5.8 (range, 3~12) months follow-up. RESULTS: Signal data not having drift or noise were adequately processed and displayed in a real time. Specifically, data upload with use of multi-processing overay display function was appropriately embodied. Overall data and profiles of patients groups were safely saved, sorted, and reproduced by using the upgrading database management software. Regarding to the therapeutic outcomes, 63 percent of 27 overall patients (12 of 17 patients in group I, 5 of 10 patients in group II) were improved. The subjective symptoms of 2 patients in group I were recurred in a period of 3 months follow-up. CONCLUSIONS: Hardware and software functions of upgraded system were applicable to the Windows environment of personal computer. A developed system with second stage software made it possible to perform biofeedback treatment. Specifically, current results could be useful for the improvement of the motivation and patient's willingness in the self-learning process of biofeedback treatment.

OBJECTIVE: Multipotent bone marrow stromal cells have the ability to differentiate toward a variety of connective tissue lineages including cartilage. The future use of adult mesenchymal stem cells (MSCs) for human therapies depends on the establishment of preclinical studies. Therefore, in this preclinical study we demonstrated the expression of MSC surface markers CD29, CD105, and CD44 on human bone marrow derived stromal cells during chondrogenic differentiation. METHODS: Adult human bone marrow was collected from the iliac crest of 7 donors following informed consent. Mononuclear cells were isolated, incubated in monolayers, and embedded in alginate beads for three-dimensional cultures. Cellualr viability was assessed by MTT assay. Flow cytometry of alginate bead cultures was performed on days 0, 7, 14, 21, and 28 using monoclonal antibody against surface molecules, CD105, CD29, CD44, CD34 and CD45. Total contents of collagen and glycosaminoglycan (GAG) of the alginate beads was measured. SPSS 11.0 was used for data analysis. RESULTS: After 7 days of culture, 89% of the cells expressed the human integrin beta 1 antibody, CD29. The CD29-positive cells remained elevated at 83% on days 28. However, while only 18% expressed the type II TGF-beta receptor endoglin, CD105 on day 7, the CD105-positive cells increased abruptly 65% on day 14 remaining elevated up to day 28. The expression of CD44 was maximal in the first passage cell (63%). High concentration of TGF-beta 3 (10 ng/mL) was more favorable for sustaining cell viability than a low concentration (0.5 ng/mL)(n=4, p= 0.002, day 21). The total contents of collagen and GAG in the MSC-alginate beads increased during the three-dimensional culture (n=4, p=0.02, p=0.006) suggesting its differentiation into a chondrogenic lineage. CONCLUSION: CD29 was expressed earlier than CD105 during chondrogenic differentiation of human bone marrow MSC. CD44 expression was highest in the first passage cells and gradually decreased afterwards.

TBX21 (T-bet) is a member of the T-box family of transcriptional factors that contain a conserved DNA binding domain. TBX21 is a critical regulator of the commitment to the Th1 lineage and IFN-gamma production. Th1 and Th2 cells cross-regulate the differentiation of each other, and in this way TBX21 could be an attractive candidate gene for treating autoimmune disease such as rheumatoid arthritis (RA). In present study, we analyzed the genotypic frequencies of six polymorphisms of the TBX21 gene between the 367 RA patients and the 572 healthy controls. We showed that the g.-1514T>C and c.99C>G polymorphisms are suggestively associated with RA susceptibility. It is interesting that the genotypic frequencies of the TBX21 polymorphisms (g.-1514T>C and c.2103A>C) in the male RA patients were significantly different from the male control group (P = 0.0016 and 0.045, respectively). We also found that the g.-1514T>C and c.2103A>C polymorphisms of the TBX21 gene in the male RA patients have significant association with the levels of anti-CCP (P = 0.05) and rheumatoid factor (P = 0.03), respectively. These results suggest that the polymorphisms of the TBX21 gene might be associated with the susceptibility to male RA patients.

Leiomyomas are common benign uterine tumors. However, the incidence of vaginal myoma is very rare and may be confused with a variety of vaginal tumors. We report a case of 43-year-old nulligravida who presented with a protruding painful vaginal mass for 7 days. The mass had initially appeared 3 years prior, as 2 to 3 cm that had not subsequently increased. However suddenly, there was rapid severe enlargement over the course of 7 days. Physical exam revealed a monstrous shaped, black color with focal necrosis, odorous protruding vaginal mass about 7 cm in size. The vaginal mass was infected and degenerated. And vaginal wall was also destroyed by the enlarged mass. Because of the clinical features and radiologic findings, the preoperative diagnosis was a vaginal malignancy. We reported an extremely rare case of vaginal myoma that had several characteristics of malignancy, with a brief review of the literature.

Acute pancreatitis has two mortality peaks, which occurs within the first 2 weeks due to organ failure and then weeks or months later as result of multi-organ failure and local complications. Although there have been several clinical and multidisciplinary evaluation measures, imaging tests, and serological tests proposed to forecast severe acute pancreatitis, there is still no single test available to reliably predict the disease severity and time of death. Future large-scale studies are required to develop an assessment scale that can accurately predict the prognosis and mortality risk of severe acute pancreatitis.
