BACKGROUND: In recent years gonorrhea has been pandemic and remains one of the most common sexually transmitted diseases(STD) in the world, especially in developing countries. OBJECTIVE & METHOD: For the detection of a more effective therapeutic regimen and to assess the prevalence of penicillinase-producing Neisseria gonorrhoeae (PPNG), we have been studying patients who have visited the VD Clinic of Choong-ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. RESULTS: In 1995, 97 strains of N. gonorrhoeae were isolated, among which 41(42.3%) were PPNG. CONCLUSION: Since the prevalence of PPNG was reported as 21.9% in 1981, the rate fluctuated. However, in 1993, there was an increase up to 74.3%. Thereafter, the prevalence rate decreased to 64.3% in 1994 and 42.3% in 1995. These changes will therefore need continuous observation.

Mixed Mullerian tumors are rate uterine malignancy and occur primarily in postmenopausal women. We have experienced three case of pathologically proven mixed Mullerian tumor. Two cases had prior history of pelvic irradiation for uterine cervical carcinoma. We suggest that mixed Mullerian tumor should be suspected when an enlarged uterus with polypoid masses in the uterine cavity are initially observed in postmenopausal women who had history of pelvic irradiation.

Toward the beginning of the twenty-first century, the world experiences the dramatic changes in politics, economics and culture, and it is evident that the Korean medical field will not be able to survive provided it doesn't prepare ourselves to adapt to those changes. The Korean Medical Society held a forum for the active operation of the medical society, inviting several leading affiliated societies, to meet the needs of the times. This review describes the summary of the presentation that the authors made on behalf of the Korean Radiological Society in the forum, including the organization, current status of academic activity, current status of international communication, and problems encountered in the internationalization of the Korean Radiological Society.

BACKGROUND: Acyclovir is a highly effective antiviral agent specifically inhibiting the replication of members of the herpes virus group, in particular the has been used extensively herpes simplex virus types 1 and 2 and the varicella zoster virus. Although acyclovir it has not caused for the treatment or prevention of herpes simplex and varicella zoster virus infections, significant changes in virus sensitivity. OBJECTIVE: The purpose of this study was to evaluate the sensitivity of HSV to acyclovir. METHODS: A total of 80 strains were used 43 strains of non-genital herpes and 37 strains of genital gerpes. These were isolated from 80 patients and were studied to evaluate their sensitivities to acyclovir by the plaque reduction assay. The methods employed to monitor the sensitivity of virus isolates rely on simple dose-response experiments, looking at the effects of increasing concentrations of acyclovir on infected cell culture specimen. The assay is based on quantified plaque counting. The sensitivity of virus strains are then expressed as ID50(concentrations of drug reducing viral cytopathic effect by 50%) and MIC(minimum inhibitory concentration). RESULTS: The results were summarized as follows. 1. The ID50 values of acyclovir for HSV ranged between 0.0625 - 4.0 microgram / ml. For non-genital herpes isolates the mean and median values were 0.459 microgram / ml (SD = 0.624) and 0.250 microgram / ml ; for genital herpes isolates these values were 0.649 microgram / ml (SD = 0.746) and 0.50 microgram / ml . 2. The MIC values of acyclovir for HSV ranged between 0.250 - 32 microgram / ml . For non-genital herpes isolates the mean and median values were 2.605 microgram / ml (SD = 5.270) and 1.00 microgram / ml ; for genital herpes isolates these values were 2.716 microgram / ml (SD = 3.015) and 2.00 microgram / ml . 5. 93.75%(75 strains) of HSV isolates were within the ranges of sensitive HSV strains for acyclovir. CONCLUSION: We are concerned about the resistance of viruses to antiviral drugs, but so far, this has not been documented to be a big problem. With the increasing interest and ability to measure sensitivity of viruses to antiviral drugs we will find out more about viral resistance and its clinical significance.

BACKGROUND: Insulin resistance syndrome shows extreme insulin resistance and is associated with acanthosis nigricans. We can differentiate it into type A insulin resistance that has insulin receptor defect, and type B insulin resistance due to insulin receptor autoantibody. Type B insulin resistance was firstly described by Kahn in 1976. It was often found in adult female and showed autoimmune characteristics. As clinical characteristics, there are hyperglycemia, hypoglycemia, hyperinsulinemia, extreme insulin resistance and acanthosis nigricans. METHODS: We investigated 17 insulin receptor autoantibody positive cases and 8 cases of normal control who had visited Wonju Christian Hospital from October 1994 to December 1995. Among insulin receptor autoantibody positive subject, male was 4 cases and female 13 cases. Their mean age was 42.2. We compared patients who had insulin receptor antibody positive acanthosis nigricans(IRA) with normal controls. IRA patients were 6 cases(35.3%) of nomal glucose tolerance, 11 cases(64.7%) of abnormal glucose tolerance including overt diabetes mellitus. RESULTS: The 11 cases(64.7%) among IRA patrents were obese and 13 cases(76.5%) had hyperininsulinemia. In IRA patients, mean serum insulin concentration during oral glucose tolerance test was 202.1mU/mL and it was greater than 46.3 of normal controls. Insulin sensitivity in 1.79mg/L * mM * xmU * min normal controls was higher than 0.74mg/L * mM * min of IRA patients. CONCLUSION: IRA patients showed abnormal glucose tolerance including overt diabetes millitus, severe insulin resistance, hyperinsulinemia and obesity.

CT findings of 19 kidneys in 12 patients with renal and perirenal non-Hodgkin's lymphoma were retrospectively reviewed to determine distinguishing characteristic and specific findings. CT manifestation of the renal and perirenal lymphoma included multiple nodules in five kidneys(26.3%), trans-capsular infiltration in three kidneys(15.8%). trans-sinus infiltration in nine kidneys(47.4%) and diffuse infiltration in two kidneys(10.5%0. Perirenal changes were thickening of the renal fascia in ten kidneys(52.6%) and crescentic lesion of low attenuation in the subcapsular area in five kidney(26.3%). Retroperitoneal lymphadenopathy was evident in eleven patient(57.9%). Renal calyceal dilatation without renal pelvic dilatation(selective calcelal dilatation) was noted in three kidneys. Familiarity with these CT findings of renal and perirenal lymphoma may be helpful in the diagnosis and management of patient with non-Hodgkin's lymphoma.

Primary hypothyroidism can result in reactive enlargement of the pituitary gland which is indistinguishable from primary pituitary lesions in clinical presentation and on magnetic resonance imaging. A 17-year-old girl came to the hospital due to short stature, general weakness and galac-torrhea. The magnetic resonance imaging (MRI) study showed pitutary enlargement. The hormone study showed hyperprolactinemia, decreased basal growth hormone level and primary hypothyroi-dism. By thyroid replacement therapy only, mass was successfully regressed on follow up MRI after 4 months, and growth acceleration could be achieved.
