Lipoma Arborescens is rarely encountered in hip joint. This term was first used by Mueller in 1838, to describe a fatty trmor of the knee which presented branched villous-like projection. The etiology is unknown, Suggests its probable reationship to tuberculosis, rheumatoid arthitis, trauma, chronic inflammation, diabetes mellitus and degenerative arthritis. It frequently involves knee joint, hand, wrist, foot, ankle, tendon sheath and hip joint. It usually presents bilaterally. Their nonspecific symptoms and signs are mild pain, joint swelling with minimum effusion, festriction of joint motion, redness, local heating and crepitus. We experienced a case of lipoma arborescens of hip joint, which was treated by synovectomy with excision of lesion.

Clinical education is difficult for actual practice of medical students. In particular, the practice in the field of obstetrics is more difficult to many students. Moreover, the education of sub-fields of obstetrics such as birth or abortion needs many materials of women's reproductive organs. However, the ordinary paper-based textbooks have some limitations for clinical education of obstetrics. The electronic textbook system based on multimedia data enables that many student, doctor, and public user overcome these difficulties, as a computer assisted learning. We developed multimedia database system which is connected with web using ODBC(Open DataBase Connectivity)and ASP(Active Server Page)/IDC(Internet DataBase Connection). Many text and multimedia data are gathered in the database. This system serves various multimedia data using internet and intranet in the student's class or home. In conclusion, providing multimedia data of obstetrics using ODBC, ASP/IDC method reduce the limitation of clinical education. This model of the electronic textbook would be a reference to develop multimedia database on the network.

BACKGROUND: Ambulatory blood pressure monitoring is widely available in clinical practice. To evaluate the pattern of normal 24 hour variation of blood pressure and the problems in analysis of data which was obtained with use of automatic blood pressure recorder, 24 hour ambulatory blood pressure was measured. METHODS: Ambulatory blood pressure was recorded for 24 hours with automatic blood pressure monitor in 22 normotensive young adolescents. RESULTS: 1) Average 24-hour BP was 109mmHg in systolic(115+/-30 for male, 102+/-30 for female), 66mmHg in diastolic(69+/-18 for male, 63+/-19 for female) and pulse rate was 72 beats per minute(70+/-23 for male, 75+/-26 for female). 2) Data obtained from ambulatory blood pressure monitor should be analyzed after deletion of unacceptable data with use of conventional criteria. Blood pressure increase which is not accompanied by increase in pulse rate increase can be used as another criteria to rule out unacceptable blood pressure data. 3) Blood pressure was low from mid-night to 6 A.M. and began to rise slowly till mid-day and then maintained steadily through the remainder of the day. And 24 hour variation of blood pressure was more adequately assessed after application of Fourier analysis. CONCLUSIONS: These results suggest that certain deletion criteria was inevitable during analysis of the data which were obtained from ambulatory blood pressure recorder and Fourier analysis can be used as valuable smoothing technique to assess the 24-hour blood pressure profiles.

Scrub typhus, an acute febrile infectious disease caused by R. tsutsugamushi, has been reported from various parts of the far east and pacific rim of Asia including Korea. It is well known that all human pathogenic rickettsia share an affinity to endothelial cells of the small blood vessels and evoke vascular inflammation variably associated with a rash, microthrombi, and hemorrhage. We infected the ICR mice by inoculating sublethal doses of R. tsutsugamushi R19 strain intraperitoneally and observed the pathologic changes by time sequence. The histopathologic features of experimentally induced scrub typhus in the mice were generally nonspecific interstitial inflammations characterized by interstitial pneumonitis, periportal inflammation, multifocal hepatic necrosis, interstitial nephritis, sinusoidal engorgement, and lymphohistiocytic cell infiltration in lymph nodes and spleen. Contrary to the general features of other rickettsial diseases, the pathologic process of scrub typhus experimentally induced by R. tsutsugamushi R19 strain mainly involved the interstitial connective tissue but not the blood vessels.

We tried to assess the effect of sequential intermittent pneumatic compression therapy in patients with lumphedema and analyze the potential prognostic factors in response to the therapy. Ninety lymphedema patients were i ncluded in the analysis. Among them, thirty-six subjects who were in clinical stage 2 or 3, infection-free and free of documented metastasis in the involved extremity were treated with the Lympha-Press. All patients were admitted for 3 days clinical trial. Comparison of circumferential limb measurements before and after a 3-day treatment period was performed. As a result of sequential intermittent pneumatic compression therapy, the volume reductions of arm and leg were 37.95(12.27% and 35.21%(24.42%, respectively. The calf, wrist and lower forearm levels showed the greatest reduction. In contrast with this, the proximal levels of arm and leg showed comparatively boor reduction than distal levels. Almost 90% of arm patients and 76% of leg patients experienced significant reduction (>25%) after therapy. The previous history of secondary infection was significantly associated with the extent of initial leg edema. But the duration and the previous history of radiotherapy or secondary infection were not a negative prognostic factor for response of pneumatic compression therapy. This study clearly indicates that sequential intermittent pneumatic compression therapy is an effective treatment for lymphedema regardless of the duration of edema and previous history of radiotherapy or secondary infection.

Pervanadate, a complex of vanadate and H2O2, has an insulin mimetic effect, and acts as an inhibitor of protein tyrosine phosphatase. Pervanadate-induced phospholipase D (PLD) activation is known to be dependent on the tyrosine phosphorylation of cellular proteins and protein kinase C (PKC) activation, and yet underlying molecular mechanisms are not clearly understood. Here, we investigated the signaling pathway of pervanadate-induced PLD activation in Rat2 fibroblasts. Pervanadate increased PLD activity in dose- and time- dependent manner. Protein tyrosine kinase inhibitor, genistein, blocked PLD activation. Interestingly, AG-1478, a specific inhibitor of the tyrosine kinase activity of epidermal growth factor receptor (EGFR) blocked not only the PLD activation completely but also phosphorylation of p38 mitogen- activated protein kinase (MAPK). However, AG-1295, an inhibitor specific for the tyrosine kinase activity of pletlet drived growth factor receptor (PDGFR) did not show any effect on the PLD activation by pervanadate. We further found that pervanadate increased phosphorylation levels of p38, extracellular signal-regulated kinase (ERK) and c-Jun NH2-terminal kinase (JNK). SB203580, a p38 MAPK inhibitor, blocked the PLD activation completely. However, the inhibitions of ERK by the treatment of PD98059 or of JNK by the overexpression of JNK interacting peptide JBD did not show any effect on pervanadate-induced PLD activation. Inhibition or down-regulation of PKC did not alter the pervanadate-induced PLD activation in Rat2 cells. Thus, these results suggest that pervanadate-induced PLD activation is coupled to the transactivation of EGFR by pervanadate resulting in the activation of p38 MAP kinase.

Hemobilia is a rare upper gastrointestinal (GI) bleeding phenomenon usually caused by trauma but may occur due to various liver and pancreatobiliary diseases. Causes related to gallbladder disease include vascular disorders, malignancy, polyps, heterotopic GI mucosa, acalculous inflammation, and most commonly gallstones. Most cases are treated with a cholecystectomy. If hemobilia is detected, efforts must be made to exclude malignancy because hemobilia develops from both benign and malignant disease. Particularly in gallbladder disease with hemobilia, the possibility of gallbladder carcinoma should be considered. We report two cases of hemoblia by endoscopic retrograde cholangiopancreatography and duodenoscopy, with a review of the literature. The first case was xanthoglanulomatous cholesystitis and the second case was gallbladder cancer disclosed by cholecystectomy.

BACKGROUND: Prevalence of class A extended-spectrum beta-lactamases (ESBLs) has been investigated repeatedly in members of family Enterobacteriaceae in Korea, but only rarely in Acinetobacter baumannii and Pseudomonas aeruginosa. The aims of this study were to determine the prevalence of class A ESBL-producing A. baumannii and P. aeruginosa and to characterize the genotypes. METHODS: During the period of June to September 2004, clinical isolates of A. baumannii and P. aeruginosa were collected from patients in Kosin University Gospel Hospital, Busan, Korea. Antimicrobial susceptibility was determined by the disk diffusion and the agar dilution methods, and ESBLproduction by the double-disk synergy test. Transferability of ceftazidime-resistance of ESBL-producers were tested by conjugation. The isoelectric points of ESBLs were determined by isoelectric focusing. Searches for blaTEM, blaSHV, blaCTX-M, blaPER-1, blaVEB, and blaGES/IBC genes were performed by PCR amplification, and the genotypes of ESBLs were determined by a direct nucleotide sequence analysis of the amplified products. RESULTS: A total of 58 clinical isolates of A. baumannii and 77 P. aeruginosa were collected. Three (5.2%) isolates of A. baumannii and four (5.2%) P. aeruginosa isolates showed positive results in the double-disk synergy test using ceftazidime and imipenem disks, and one (1.7%) A. baumannii and two (2.6%) P. aeruginosa isolates showed positive results in that test using ceftazidime and cefoxitin disks. The most prevalent class A ESBL genotype in A. baumannii isolates was blaPER-1 (n=6), and blaSHV-12 gene was also found in one P. aeruginosa isolate. CONCLUSIONS: It is concluded that class A PER-1 ESBL-producing A. baumannii isolates are spreading, and SHV-12-producing P. aeruginosa has emerged in Korea. The spread of class A ESBLs could compromise the future usefulness of expanded-spectrum -lactam antibiotics for the treatment of A. baumannii and P. aeruginosa infections.

OBJECTIVE: To evaluate the degree to which the paralysis of a dominant hand affects quality of life (QOL) in patients with subacute stroke. METHODS: We recruited 75 patients with subacute hemiplegic stroke. Patients were divided into two groups according to the location of the lesion and the side of the dominant hand. Group 1 consisted of patients whose strokes affected the dominant hand (i.e., right hemiplegia and right dominant hand or left hemiplegia and left dominant hand). Group 2 consisted of patients whose strokes affected the non-dominant hand (i.e., left hemiplegia and right dominant hand or right hemiplegia and left dominant hand). The primary outcome measure was the Short-Form 36-Item Health Survey (SF-36), which was used to evaluate health-related QOL. Secondary outcomes were scores on the Modified Barthel Index (MBI) and Beck Depression Inventory (BDI). RESULTS: We did not find any statistically significant differences between the groups in any SF-36 domain including the summaries of physical and mental component. Similarly, the MBI and BDI scores were not significantly different between the groups. CONCLUSION: The effect of paralysis on the dominant hand and QOL in patients with subacute stroke was not significantly different from the effect of paralysis on the non-dominant hand.
