In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

부비동의 악성임파종은 매우 빈도가 적으나 방사선치료로 완치가 가능한 종양이다. 내원당시 병변은 부비동과 그 주위에 국한되어 있으며, 전신적인 임파종으로의 변환은 흔치 않다. 대부분 부비동 임파종은 병리조직학적으로 조직구성 임파종이다. 원발병소와 경구임파절의 방사선 치료가 가장 적절한 치료이며 50~70%의 생존율을 기대할 수 있다. Malignant lymphoma of the sinus is very rare but potentially radiocurable neoplasm. The disease is tend to be localized to the sinus and spread to adjacent local structures on initial presentation, and change to generalized lymphoma is uncommon. Most of sinus lymphoma is diffuse histiocytic type. Radiotherapy to the primary and neck nodes is the treatment of choice, and a survival rate of 50-70% can be expected.

1981년 3월부터 1986년 3월까지 고려대학교 의료원 혜화병원 치료방사선과에서 60명의 두경부 환자를 대상으로 방사선치료후의 임상적인 병기에 따른 생존율 및 국소종양 억제율을 후향적으로 재조사하였다. 근치적 방사선 치료전에, 이학적 검사와 방사선학적 검사로 흉부X-선, 후두촬영 및 콤퓨터 단층촬영 등을 시행하였고 AJC의 임상병기에 따라 분류하였다. 치료는 방사선 치료 단독 시, 7,200cGy를 8주에, 그리고 수술후 방사선 치료시는 6,000cGy를 7주에 각각 분할 조사하였다. 이에 저지들은 다음과 같은 결과를 얻었다. 1) 남녀의 성비는 3.6:1이었고 50대의 연령군에서 가장 높은 빈도를 보였다. 2) 방사선 치료를 받은 환자에서, 병리조직하적으로 편평상피암이 비 편평상피암에 비해 3.5배의 높은 빈도를 보였다. 3) 원발병소의 해부학적 위치는 후두가 22예, 부비동이 12예, 비인후강이 7예, 구강인두가 6예, 하인두가 3예였다. 4) AJC의 병기에 따라 분류하면 I기가 4예, II기가 7예, III기가 19예, 그리고 IV기가 27예였다. 5) 경부임파절로의 국소전이는 전체적으로 43%였고 subdigastric과 submaxillary임파절이 가장 않은 것으로 나타났다. 6) 방사선 치료 후 국소종양의 억제는 치료 환자의 48%에서 관찰되었다. 7) 원격전치는 7예에서 관찰되었는데 그중 4예에선 폐로의 원격전이를 보였다. 8) Life-table방식에 의한 5년 생존율은 43%로 나타났다. Study patients with head and neck carcinoma were studied retrospectively to assess the impact of treatment on survival and local control rate by stage in the Dept of Radiation Therapy, Korea University Hae Wha Hospital between March 1981 and March 1986. Prior to definite radiotherapy, patients were evaluated by physical examination and radiologic studies including chest, laryngogram and CT scan and then these patients were grouped according to the American Joint Committee (AJC) staging system. They were treated with RT alone or postoperative irradiation to the dose of 7,200 cGy/8 weeks and 6,000 cGy/7 weeks respectively. The results were obtained and as follows; 1. Overall male to female sex ratio was 3.6:1. The peak age of patients with head and neck cancer was 6th decade. 2. In all patients treated by RT, the ratio of squamous cell 1 carcinoma to non-squamous cell carcinoma was 3.5:1 (60/77 patients). 3. The incidence according to the anatomic site of primary tumor was 22 cases in the larynx, 12 cases in PNS, 7 cases in nasopharynx, 6 cases in oropharynx, and 3 cases in hypopharynx. 4. According to AJC staging system,4 cases were Stage 1,7 in Stage II, 19 in Stage III and 27 in Stage IV. 5. The overall incidence of cervical lymph node metastases was 43% and subdigatric and submaxillary triangle lymph nodes were the most frequent site of metastases. 6. Local control was achieved in 48% of patients treated by radio-therapy. 7. The lung was the most common site for distant metastases, comprising 4 cases among 7 cases in which distant metastases occured. 8. The overall estimated 5-year survival rate was 43% in the head and neck cancer treated with radiotherapy by life-table analysis.

원발성 안구 흑색종은 20세 이상의 성인에서 가장 많이 발생되는 안주의 악성종양이지만 한국에서의 발생빈도는 그리 흔하지 않은 것으로 되어 있다. 안구 흑색종의 치료전에는 문진, 이학적검사, 기본적인 혈액상검사와, 특히 간, 폐, 골에 세심한 주의를 하여야 하며, 그래서 흉부 X-선과 LDH, SGPT, Transpeptidase를 포함한 간기능 검사 등을 시행하여야 하고 만약 임상적으로 증상이 있거나 위의 검사상 비정상적인 소견을 보일 매에는 전신뼈 스캔, 간-지라 스캔을 시행하여야 한다. 일반적으로 악성 흑색종은 방사선 치료에 대해 치료효과가 나쁜 것으로 알려져 있지만 때로는 총 종양조사선량 7,000~8,000 cG/8~9주로 매우 빠른 종괴의 감소를 보여 주기도 한다. 그리하여 저자등은 외부방사선조사로 빠른 치료반응을 보인 원발성 안주 흑색종의 치료와 문헌고찰을 보고하는 바이다. Intraocular melanoma is the most common primary occular malignancy in adult above the age of 20. Before treatment of intraocular melanoma, it is essential to do complete work-ups including LFT (LDH, SGPT), chest X-ray, whole body bone scan. Also, liver-spleen and brain scan will be done if clinically indicated. Though, malignant melanoma is radioresistant, however, show rapid tumor shrinkage after irradiation with total tumor dose of 7,000 to 8,000 rads in 7-8 weeks.

Background/Aims: The true incidence of aristolochic acid nephropathy (AAN) is thought to be underestimated because numerous ingredients known or suspected to contain aristolochic acid (AA) are used in traditional medicine in Korea. Methods: We collected data on cases of AAN since 1996 via a database in Korea. We evaluated the year of AAN development, route to obtaining AA-containing herbal medicine, gender, reason for taking AA-containing herbal medicine, clinical manifestations, histological findings, phytochemical analysis, and prognosis of patients with AAN. Results: Data on 16 cases of AAN were collected. Thirteen cases developed AAN before and three cases after the prohibition of AA-containing herbal medicine by the Korea Food and Drug Administration. Patients were prescribed AA-containing herbal medicine from oriental clinics or had purchased it from traditional markets. AAN was distributed in all age groups. Young females were most commonly exposed to AA-containing herbal medicine for slimming purposes and postpartum health promotion, while older adults took AA-containing compounds for the treatment of chronic diseases. The most common symptoms presented at hospitalization were nausea and vomiting, and acute kidney injury was accompanied by Fanconi syndrome in almost half of the patients. Phytochemical analysis of AA in herbal medicine was available in six cases. Progression to end stage renal disease (ESRD) was observed in seven patients (43.8%), and five patients (31.3%) had progressed to ESRD within 6 months of diagnosis. Conclusions: Our report shows that patients were still exposed to AA-containing herbal medicine and that there is a possibility of underdiagnosis of AAN in Korea. A stronger national supervision system of herbal ingredients and remedies in oriental medicine is needed to prevent AAN.

Ventricular fibrillation is one of the most common causes of sudden cardiac arrest in adults. A lot of research has been done on ventricular fibrillation. However, that research draws conclusions from animal studies and they could not induce artificial ventricular fibrillation in human subjects. This paper looks at whether there is a difference between ventricular fibrillations in animal models and in human models, with comparisons of ventricular fibrillation obtained from the two groups. This study compares and analyzes electrocardiography (ECG) wave forms as electrical bio-signals of the two groups, in which the histogram of gradient (HOG) and auto-associative multilayer perceptrons (AAMLP) are applied for feature extraction and pattern analysis, repsectively, of the bio-signals. The characteristics of electrical signals in animal ventricular fibrillation and those in human ventricular fibrillation are conclusively similar and it is reasonable to adapt the results obtained from animal research to clinical practices.
