PURPOSE: Acute pyelonephritis of growing kidneys may result in renal scarring. TGF-beta, inflammatory cytokine, has been suggested to play an important role in promoting renal scarring through apoptosis, suppression of cellular proliferation and fibrosis. We observed the effects of a potent anti-inflammatory agent, methylprednisolone on apoptosis and renal scarring in experimentally induced acute pyelonephritic weaning rats. MATERIALS AND METHODS: To induce ascending pyelonephritis a saline solution containing Escherichia coli type ATCC No. 25922, pili-form (107 bacteria/mL) was infused into the bladder through the 16-guage silicone cannula for 48 hours to 102 three-week-old Sprague-Dawley rats (50-60g). Experimental groups were divided into three groups according to the treatment protocols, group I (ceftriaxone only, n=31), group II (methylprednisolone+ceftriaxone n=28), control group (n=43) was not treated. Histopathologic scores of inflammatory changes, fibrosis and tubular atrophy, the apoptosis index and TGF-beta1 expression score were observed at post-infection 1 and 3 week. Datas were analysed using ANOVA test and P value below 0.05 was interpreted as significant. RESULTS: The mortality rate (21.4%) of group II was not different to the control group (41.9%) and group I (32.3%). The inflammatory score of group II (0.8+/-0.87) at week 1 was significantly lower than those of the control group (2.3+/-0.87) and Group I (1.7+/-0.79) (P<0.05). Apoptosis index of group II (2.9+/-2.15) at week 1 was significantly lower than (10.0+/-0.95) and group 1 (8.3+/-2.53) (P<0.05). TGF-beta1 expression score of group II (0.8+/-0.72) at week 1 was significantly lower than those of the control group (1.9+/-0.68) and group I (1.8+/-0.60) (P<0.05). The fibrosis score of group II (1.1+/-0.10) at week 3 was significantly lower than that of the group I (1.8+/-0.83) (P<0.05). CONCLUSION: Combined treatment with methylprednisolone and ceftriaxone reduced inflammation, fibrosis, apoptosis and TGF-beta expression in acute pyelonephritic weaning rats, compared to ceftriaxone alone. Anti-inflammatory agent supplemented to antibiotics could prevent renal scarring more effectively.

In 97 cases of uncomplicated Cesarean section proceeding under 0.5% fluothane anesthesia with N2O and O2, 2.5% Pentothal sedium(clinical induction doses) was enough until umbilical cord clamp without any supplemental doses but muscle relaxation from succinylcholine might not be potentiated with 0.5% fluothane. On the other hand, Apgar score and postpartum uterine contractility was depending upon duration of anesthesia but it was not so serious problem. Also, anesthesia induction and recovery was rapid, and post operative pulmonary and other complication, even vomiting, did not occur. Conclusively, it is interesting that low concentration of fluothane with nitrous oxide are probably ideal anesthesia method for Cesarean section.

OBJECTIVES: Our study was to determine the usefulness of CA 125 screening for asymptomatic female subjects. Though CA 125 has been used as a useful marker for the detection of ovarian cancer, its efficacy to detect early ovarian cancer in asymptomatic women has not been established. STUDY DESIGN: From April 1995 to December 1997, a total of 13,038 subjects who visited our Center for Health Promotion were screened. Serum CA 125 level was measured by a radioimmunoassay kit (Centocor, USA). In most cases transvaginal ultrasound was done at the same time. The specificity, sensitivity and positive predictive value were obtained on the basis of normal CA 125 range between 2.4~36.3 U/ml. RESULT: 1) Two cases of ovarian cancer were detected out of 13,038 subjects screened. One ovarian cancer patient showed 1,625 U/ml of CA 125 level, on the other hand, the other level patient showed 27 U/ml. 2) Therefore, the sensitivity, specificity, and positive predictive value were 50%, 97.3%, and 0.3%, respectively. Since 346 cases out of 13,038 screened subjects showed false positive results on the basis of the upper limit of normal CA 125 level set at 36.3 U/ml,the false positivity was 2.6%. 3) The CA 125 levels in false positive cases ranged from 36.3 U/ml to 352.8 U/ml with the mean value of 66.19+/-51.47 (S.D.). 4) The clinical features of the false positive cases included uterine myoma including adenomoysis (150), benign ovarian cyst (19), cervicitis (6), tuberculosis (3), pregnancy (2), and each one case of breast cancer, mammary cyst, endometritis, lung cancer, liver cirrhosis, pancreatic cancer, cervical cancer, renal cyst, uterine anomaly, and post TAH state. In the remainder of false positive 156 cases, no abnormal findings were observed. Among 258 pateints who underwent combined tests of CA 125 and transvaginal ultrasound, the sensitivity of ovarian cancer was 100%. 5) The false positive rate was lower in the older age group (>50) than in the younger group (<50). CONCLUSION: The prevalance of ovarian cancer in our study was 0.0153% (15.3 per 100,000 population) which is comparable to the rate of 15.8 per 100,000 population reported by the Korean Medical Insurance Corporation. Although the CA 125 test by itself shows a low positive predictive value, its clinical usefulness as a screening test can be enhanced dramatically by the combined use of transvaginal ultrasound examination, especially in postmenopausal women.

Macroglobulinemia is the result of an uncontrolled proliferation of lymphocytes and plasma cells in which a large IgM M protein is produced. IgM monoclonal gammopathy is recognized in a variety of lymphoproliferative diseases and Waldenstr?m's macroglobulinemia (WM) is the most frequent disease in this group. We report a case of nodal marginal zone B-cell lymphoma (Nodal MZBCL) accompanied by monoclonal macroglobulinemia. A 58-year-old man was admitted to the hospital with chronic fatigue and dyspnea. Physical examination revealed cervical, subaxillary, and inguinal lymphadenopathy. Histopathologically, monocytoid B cells with abundant pale cytoplasm and small nuclei infiltrated the cervical lymph node. The neoplastic cells were positive for CD 20, bcl-2, and IgM. The serum and urine electrophoresis showed monoclonal spike in the globulin region and immunoelectrophoresis demonstrated immunoglobulin of IgM, kappa type. Immunohistochemically, this monoclonal gammaglobulinemia (IgM, Kappa) was produced and secreted from the nodal MZBCL. This is the first report of nodal MZBCL accompanying macroglobulinemia in Korea.

OBJECTIVE: To determine the clinical value of human papillomavirus deoxyribonucleic acid(HPV DNA) testing by polymerase chain reaction(PCR), specifically to examine whether HPV testing could identify the women with Pap smears read as mostly atypical squamous cells of undetermined significance(ASCUS) or more. METHODS: HPV DNA testing by PCR for 3 high-risk cancer associated genotypes(HPV 16, 18, 33), repeat Pap smears and colposcopically directed punch biopsies were performed concurrently on 169 women referred for cervical cancer screening test with a previous Pap smear read as ASCUS or more. RESULTS: HPV DNA testing positivity was significantly associated with abnormal cytology and high-grade squamous intraepithelial lesion(HSIL) and squamous cell carcinoma(SCC) in histology(P=0.034). The sensitivity, specificity, positive predictive value(PPV), negative predictive value(NPV) of Pap smear and HPV testing for identifying 38 cases of histologically confirmed HSIL and carcinoma by different triage protocols(HPV positive or HSIL or SCC) among 169 women were 65.8%(25/38), 85.5%(112/131), 56.8%(25/44) and 89.6%(112/125), respectively. Also sensitivity, specificity, PPV and NPV were varied by ages and more higher in older. CONCLUSION: HPV DNA testing by PCR appears to offer an effective means by which women whose cervical Pap smears have been read as ASCUS or more could be triaged for colposcopically directed biopsy. The sensitivity for HSIL could be maintained in high and specificity markedly improved by HPV genotypes 16, 18, 33.

BACKGROUND: Onychomycosis, especially toenail onychomycosis has become one of the common fungal infection and has historically been regarded as a cosmetic rather than medical problem by many patients, even by physicians. Recently, however, there are several reports that this is a refractory disease which may cause a deleterious effect on patients' quality of life (QOL). OBJECTIVE: The purpose of this study was to investigate the impact of toenail onychomycosis on QOL in Korea and to assess the changes of QOL after treatment. METHODS: Total 1004 patients with toenail onychomycosis which was confirmed by clinical findings and KOH preparation were enrolled at 47 dermatologic centers in Korea, and interviewed with standardized QOL questionnaire before and after systemic antifungal treatment. Responses to the questionnaire were scored by f-point scale (0~4) and averaged, and were analyzed for 5 dimensions of emotional impact, social impact, symptom and functional impact, patients' views concerning treatment, and relationship with doctor. RESULTS: 1. Before and after treatment, the most serious impact was emotional dimension showing 1.90 and 1.30 in average score (AS), and social (AS: 1.14 and 0.83) and symptom and functional impact (AS: 1.05 and 0.92) was also affected. 2. In female rather than male, statistically more significant impact on patients' QOL was observed in all dimensions. 3. After treatment, 3 of 5 dimensions were improved significantly - emotional dimension (AS: from 1.90 to 1.30), social dimension (AS: from 1.14 to 0.83), patients' view concerning treatment(AS: from 1.34 to 1.02) 4. The degree of patients' satisfaction at the therapeutic effect was very high - 62.4% (immediately after. treatment) and 65.8% (9 months after initiation of treatment) of patients answered excellent or good. CONCLUSION: This study confirms that toenail onychomycosis has significant Impact on the overall QOL of patients. Also the effect of antifungal therapy on patients' QOL were satisfactory. Therefore, both doctor and patient should pay more attention to the treatment of onychomycosis.
