The involvement of health-care professionals in tobacco-control activities is essential to prevent smoking-related morbidity and mortality. The purposes of this predictive correlational study were to examine tobacco-control activities and to identify the predictors of such activities of community health practitioners (CHPs). Of the 1,813 members of the Korean Association of CHP, 1,247 participated in this study. A mailed survey was conducted to collect data. The majority of CHPs supported tobacco-control policies and recognized tobacco-control activities as an important role for them. Only 44.3% of CHPs were confident in their knowledge and skills regarding tobacco-control activities, and only 30.8% had received professional tobacco-control education. While the majority of the CHPs "asked, advised, and assessed"their clients, only a small number "assisted or arranged". The tobacco-control activities of CHPs were predicted by their attitude toward it, age, experience of tobacco-control education, educational level, and general perception of the risk of smoking; these variables accounted 13.5% of variance in the tobacco-control activities of CHPs. These findings provide the basis for developing a continuing education program for CHPs. CHPs should be encouraged to integrate tobacco-control activities into their routine practice, and CHP education programs should be adjusted to increase the time spent on the tobacco-control intervention techniques.

The cystic mesothelioma is a very rare tumor which has a clinically and histologically benign nature. Here in reported is the case of a cystic mesothelioma presented as a palpable mass of the inguinal area in a 28-year-old male. Ultrasound showed a cystic tumor at the inguinal canal, and the other physical and laboratory examinations were within normal limits. Grossly, the tumor consisted of cysts containing clear serous fluid and focally solid areas. Microscopically, the tumor was encapsulated with fibrocollagenous wall, and the tumor cells were cuboidal or polygonal epithelial cells with single or multiple layers and had clear cytoplasm. Some areas showed thyroid follicle-like structures. The content of follicle-like structures showed eosinophilia in the H&E section, but positive in mucin stain. Neither cytologic atypia nor mitoses were present. Immunohistochemical staining revealed positive reaction for keratins of low molecular weight, while negative for the thyroglobulin and CEA. These findings suggested mesothelial in origin. We concluded that this tumor was primary rather than metastatic, because he had no evidence of a tumor in gastrointestinal, genitourinary tracts and scrotum.

In treating young women for gestational trophoblastic tumor ( G.T.T. ), all efforts are made to preserve fertility and hysterectomy is avoided unless absolutely essential. However, in some cases the operation may be lifesaving. During the last 20 years among the 310 cases of G.T.T. treated at Il Sin Christian Hospital, there were 3 cases in which hysterectomy was avoided by the excision of a localized uterine lesion thus preserving fertility.

BACKGROUND: Midkine (MK) is a member of the heparin-binding growth factor family. Overexpression of MK is observed not only in cancerous tissue but also in precancerous lesions of the colon and the prostate. Using immunohistochemical methods, we investigated MK expression in preinvasive and invasive neoplasia of the uterine cervix. METHODS: We performed immunohistochemical analysis of archived cone biopsy and hysterectomy specimens from 161 squamous cell lesions of the uterine cervix (29 cervical intraepithelial neoplasia 1 (CIN1), 35 CIN2, 49 CIN3, 30 microinvasive squamous cell carcinomas (MIC), and 18 invasive squamous cell carcinoma). In addition, we examined if there is a correlation between MK expression and status of human papilloma virus infection determined by a commercially available DNA chip. RESULTS: None of the normal cervical mucosa showed MK immunostaining. The level of MK expression gradually increased according to the histologic grade. Moderate and strong expressions were most frequently observed in cervical tissue with CIN3 and MIC. MK immunostaining was more accentuated in the invasive border of MIC. CONCLUSION: MK may play a functional role in the disease progression of cervical squamous cell neoplasia.

PURPOSE: The aim of this study was to synthesize the best available evidence for active warming interventions during cesarean section. METHODS: A database search was done for randomized controlled trials utilizing active warming interventions. Maternal temperature, shivering and neonatal temperature were evaluated as outcome variables. Data were analyzed using Cochrane Review Manager software Version 5.3. RESULTS: Thirteen studies including 1306 patients were reviewed. The degree of lowering of maternal temperature decreased in the warmed fluids (MD 0.51; p=.004) and warming mattress interventions (MD 0.22; p<.001) compared with control groups. Incidence of shivering was also lower in the active warming group (OR 0.55; p=.003). There was no statistically significant difference in maternal temperature with a forced air warming intervention (MD 0.64; p=.15) or in neonatal temperature (MD 0.12; p=.26). CONCLUSION: Findings show that with warmed fluids and warming mattresses applied during cesarean sections maternal temperature decline was reduced and also the incidence of shivering declined, but no significant effect was observed for forced air warming interventions. These findings provide a basis for developing a warming guideline for women having a cesarean section and will help to improve the quality of care for cesarean section patients.

Actinobacillus actinomycetemcomitans, a gram-negative, capnophiTic bacterium, is associated with several human diseases including periodontal disease. Products of A. actinomycetemcomitans exert immunomodulatory effects on various lymphoid populations, some of which may be implicated in the pathogenesis of periodontitis. It has been recently suggested that some of periodontopathic bacterial products might possess superantigenic (SAg) activities. In order to examine SAg activity of A. actinomycetemcomitans, we tried to purify immunomodulating factor (IMF) which can induce proliferation of mouse splenocytes and human PBMC. IMF fraction was obtained from the culture supernatant of A. actinomycetemcomitans by alcohol precipitation, ultrafiltration, size exclusion chromatography, and dye ligand affinity chromatography which has been widely used for the puri5cation of known SAgs. SDS-PAGE analysis showed that the factor migrated to a molecular mass of 40 kDa. The concentration of IMF which elicited maximal proliferative response of mouse splenocytes was ranged 1-10 ug/ml of protein on day 3 in culture. Human PBMC gave a similar response profile to IMF, but their maximal response was obtained by lower concentraion of IMF on day 2 in culture. This activity of IMF was heat and proteinase K sensitive and was not blocked by co-incubation with polymyxin B, a ligand for the lipid A region of lipopolysaccharide. T cell-enriched fraction of mouse splenocytes obtained by nylon wool column lost the response to IMF. Even though mitomycin C-treated antigen presenting cells were added to T cell-enriched fraction, the response to IMF was feeble as compared to unfractionated cells. Splenocytes depleted of T cells by anti-Thy 1.2 and complement also did not respond to IMF. These findings demonstrated that T cells are responsible for a minor proportion of the observed proliferation induced by IMF and the help of these cells are essential to the most of the proliferating cells which may be B cells. This observation was confirmed by flow cytometric analysis of responding lymphocyte subpopulations. These results indicate that IMF of A. actinomycetemcomitans does not act in a manner consistent with known SAgs but is more relevant to the explanation of pathologic findings of periodontal lesions.

We describe a rapid and efficient diagnostic method for sex determination and the dystrophin gene by the polymerase chain reaction (PCR) using archived cytogenetic slides. Archived cytogenetic slides stored for about 4 years at room temperature were used. To confirm whether DNA analysis is possible using the archived cytogenetic slides, we extracted the DNA from the slides and amplified the Y centromeric region (DYZ3), the X centromeric region (DXZ1) and the exon 46 of the dystrophin gene. Of the 50 cases, 24 were peripheral bloods, 13 were amniotic fluid cells, 5 were chorionic villus samplings and 8 were cord bloods. The PCR related sex determination in 22 females and 28 males, showed 100% concordance with the results of chromosome analysis, and all cases showed positive band for the exon 46 of the dystrophin gene. Of the 50 cases of the archived cytogenetic slides, we were fortunate enough to obtain the fresh blood sample from one fetus whose karyotype showed 45,X[34]/46,X,+mar[145] to compare the results of the gDNA with that from archived cytogenetic slide. To confirm whether the marker chromosome was derived from Y chromosome, we studied the six loci (PABY, SRY, RPS4Y (SY16, 17), ZFY, DYS14) on the short arm, one locus (DYZ3) on the centromere and one locus (DYZ1) on the long arm. Of the 8 loci studies, all PCR related Y chromosome showed positive band from both gDNA obtained from cord blood and archived cytogenetic slides. We could conclude from the above results that the marker chromosome was derived from the Y chromosome. We believe our experiment is rapid and efficient for studies of over 10 independent loci from a single slide which has been kept in storage for up to 4 years and that archival Giemsa-stained cytogenetic slide repositories represent valuable DNA resources for clinical and forensic studies.

BACKGROUND AND OBJECTIVES: Benign paroxysmal positional vertigo (BPPV) generally involves a single semicircular canal (single canal BPPV) but it has been reported that more than one semicircular canal on either the same or the opposite side can be involved in 6.8-20% of the cases (multiple canal BPPV). In this study, the clinical characteristics of multiple canal BPPV were analyzed and compared to those of single canal BPPV. MATERIALS AND METHODS: Retrospective analysis was performed on 1054 consecutive patients diagnosed with BPPV. Multiple canal BPPV was diagnosed when the combination of typical nystagmus was provoked by the Dix-Hallpike and supine head roll tests. Canalith repositioning maneuver was performed sequentially starting with the semicircular canal causing more severe nystagmus or symptoms. Clinical characteristics and the treatment course were statistically compared between single canal BPPV and multiple canal BPPV. RESULTS: Among the 1054 patients, single canal BPPV was diagnosed in 1005 patients (95.4%) while multiple canal BPPV was diagnosed in 49 patients (4.6%). BPPV involving semicircular canals on the same side was more common (79.6%) than BPPV with bilateral involvement. The most common combination of the involved canals was ipsilateral posterior and horizontal semicircular canals (63.3%). Multiple canal BPPV was significantly more associated with underlying otologic diseases, especially labyrinthitis. Multiple canal BPPV required more treatment sessions and longer duration of treatment to achieve resolution of nystagmus and symptoms. CONCLUSIONS: As all cases of multiple canal BPPV were treated successfully although a longer duration of treatment and more treatment sessions were required compared to single canal BPPV, the results of our study could aid in making an accurate diagnosis and providing appropriate treatment of multiple canal BPPV.
