Angioleiomyoma(ALM) of the cavernous type is a rare subtype of leiomyomas arising from the smooth muscle of veins. ALM of this type invariably shows clinically and histopathologically distinctive features, compared with the classical solid or venous type. However, no case of ALM of this type has been yet reported in Korea although there have been several reported cases of other types. We herein present the case of a 39-year-old man with a 7-year history of a painless ALM of the cavernous type on his buttock with the histological features of markedly ectatic vascular channels and thin intervascular bundles of smooth muscles.

This study was aimed to elucidate the relationship between combinations of treadmill speed-grade and oxygen consumption(Vo2). Twenty athetic and 20 non-athletic male college students aged 19-24yr were employed to exercise on a treadmill using 4 speeds(4.02, 5.47, 6.76 and 8.05km/h) and 5 grades(0, 8, 12, 16 and 20%). A fixed speed was selected for each session with the grade increased every 3 min. The Vo2, heart rate, stride frequency and stride length were measured during the last min of each 3-min stage. Vo2increased linearly with increasing speed and grade showing significant multiple correlations in nonathletes(Vo2=3.64x+0.831y+0.031xy-7.03, R=0.98, P<0.01) and athletes(Vo2=3.48x+0.324y+0.112xy-5.74, R=0.99, P<0.01). Stride frequency and length tended to increase with increasing speed except for the transition from walking to runnig at 8.05Km/h at which the stride frequency ran up much higher with the stride length getting lower than at 6.76Km/h. Heart rate increased linearly with increasing Vo2. The rate of increase was higher during walking than during running. These results indicate that athletes have higher rate of increase in Vo2than nonathletes at near-maximal exercise and may be used as a guideline in predicting maximum oxygen comsumption and in prescribing exercise intensity.

This study aimed to develop a measure of professional identity for Korean dental hygienists and to analyze the factors and characteristics of professional identity of these dental hygienists. In this study, 890 dental hygienists completed a self-administered survey. The final analysis was conducted with a total of 880 responses, excluding 10 questionnaires with unreliable responses and partial responses. A systematic literature review was conducted to establish the definition of professional identity, while content validity, exploratory factor, confirmatory factor, and reliability analysis were conducted to establish the constructive factors. Descriptive statistics, independent sample t-test, and one-way ANOVA were used to identify the level of each factor. Authors conceptualized the professional identity for Korean dental hygienists and item generation, item reduction, and questionnaire formatting. The developed measure of professional identity for dental hygienists consisted of five factors, with 15 items. “Sense of calling,”“need for academic capacity building,”“performance of delegated authority,”“compliance of code of ethics,” and “usage of professional organizations” were the constituent factors. Based on these factors, the level of professional identity was the highest in the “performance of delegated authority” and lowest in the “usage of professional organizations.” These finding indicated that dental hygienists with higher education levels have higher professional identity levels. The dental hygienists working at the general/university hospital had the highest level of professional identity. Thus, further research is needed to establish a model that consists of factors affecting and influencing the professional identity of dental hygienists.

BACKGROUND: A pathogenesis of skin-homing lymphoid cells in primary cutaneous T-eell lymphoma(CTCL) has not been elucidated, CLA(cutaneous lymphocyte-associated antigen) defined by HECA-452 monoclonal anfibody has been proposed as the novel skin-homing receptors of infiltrative lymphocytes in atopic dermatitis and graft-versus-host disease. Accordingly, CLA may be a determinant explaining about the skin-homing properties of lymphoid tumor cells in CTCL. OBJECTIVE: This study was conducted to investigate the immunohistochemical expression of CLA in the lesional tissue specimens of cutaneous lymphomas. METHODS: Immunohistochemicslly, we examined the expression of CLA, E-selectin, ICAM-1 and LFA-1 antigens in the tissue specimens taken from the skin lesions and lymph nodes of the 22 patients with cutaneous lymphomas and the 20 control subjects with non-cutaneous lymphomas. Results : 1. The expression rate of CLA was 40.9% in the skin specimens of cutaneous lymphomas. We could not fad any expression of CLA in non-cutaneous lymphomas. 2. CTCL showed a more frequent expression of CLA(80%) than cutaneous B-cell lymphomas (CBCL)(8.3%). We found more frequently CLA+ high endothelial venules in non-cutaneous lymphomas(40%) than in cutaneous lymphomas(9.1%). 3. CLA and E-selectin were more frequently expressed in primary CTCL(100%, 83.3%) than in secondary CTCL(50%, 0%). 4. The positivity to ICAM-1 and LFA-1 antigens was higher in primary cutaneous lymphomas (72.7%, 81.8%) than in secondary forms(9.1%, 9.1%). Conclusion : CLA and E-selectin may represent the pivotal skin-homing receptor of infiltrative tumor cells and vascular counter-receptor in primary CTCL, respectively. Also, ICAM-1 and LFA-1 may have a role in the primary cutaneous infiltration of lymphoma cells as the additional cofactors.

We herein present two cases of generalized pustular psoriasis(GPP) followed by acquired bullous diseases during antipsoriatic management. Although there were several reports de-scribing the coexistence of psoriasis vulgaris and autoimmune bullous diseases such as bullous pemphigoid or pemphigus vulgaris(PV), a coexistence of GPP and bullous disease was sparcely reported. In one patient, we could define atypical autoantigen which was distinct from the other known antigens in documented cases of bullous diseases. The other case was compatible with PV. The psoriatic lesions and bullous eruptions of the two patients cleared in several weeks after administration of cyclosporine.

To investigate the association between hepatocellular carcinoma(HCC) and infection of hepatitis B virus(HBV) and hepatitis C virus(HCV) in an HBV endemic area , a case-control study of 254 patients with HCC and of 1,270 age and sex matched health control subjects was done. Among the 254 HCC patients 166(65.4%) were positive for hepatitis B surface antigen(HBsAg), 49(19.3%) were positive for HCV antibody(anti-HCV Ab). The crude odd ratio of patients with HBsAg was 36.1(95% CI :22.4-58.2) and with anti-HCV Ab was 9.0(95% CI :5.5-14.6). In an analysis, which HBsAg(-), HBcAb(-), anti-HCV Ab(-) group was chosen as referent group, odd ratio of HBsAg(+) group was 14.4(95% CI: 7.2-28.9) and of anti- HCV Ab(+) was 10.7(95% CI: 2.9-40.0). Odd ratio of anti-HCV Ab(+), HBsAg(+) group and anti-HCV Ab(+), HBsAg(-), HBcAb(+) group for HCC were elevated to 27.3(95% CI : 9.0-82.9) , 15.9(95% CI:7.1-35.8) respectly. The odd ratio of anti-HCV Ab(-), HBsAg(-), HBcAb(+) group was 2.4(95% CI : 1.1-5.0). These result suggested that HBV and HCV were associated with HCC. In HBV endemic area patients with HBcAb alone should be considered risk group for HCC.

BACKGROUND: Inflammatory bowel disease(IBD) such as ulcerative colitis or Croln's disease is often related with varied diseases including pyoderma gangrenosum, erythema nodosum, ankylosing arthritis and psoriasis. To date, however, a cIinical observation of IBD accompanied by psoriasis has been sparcely accomplished although an immunogenetic mechanism explaining a coexistence of IBD and psoriasis has been proposed. OBJECTIVE: We estimated the prevalence of IBD in patients with psoriasis in Korea and investigated the clinical characteristics of IBD accompanied by psoriasis. METHODS: 92 psoriatic patients and 389 non-psoriatic control subjects were enrolled in this study. Colonoscopic biopsy and barium series were performed in 47 psoriatic patients and 110 control subjects showing irritative intestinal symptoms. RESULTS: 1. The prevalence of IBD in psoriatic patients(14.1%) was significantly greater than in the control group(1.0%). 2. In the temporal relationship, psoriasis developed several years prior to the onset of IBD in 84.6% of psoriatic patients. 3. The frequency of arthropathies in the psoriatic patients possessing IBD(84.6%) was significantly higher than that of non-psariatic counterparts with IBD(25.0%) or that of psoriatics without lBD(2.5%), 4. The psoriatir. patients with IBD demonstrated much more frequently diffuse colonal extension than in non-psoriatic subjects with IBD. CONCLUSION: Our findings of an increased prevalence of IBD in the psoriatic population present further evidence of an association between IBD and psoriasis. In the psoriatic patients showing acute or chronic gastrointestinal symptoms, colonoseopic evaluation might be mandatory for the evaluation of IBD.
