The importance of tick-borne diseases is increasing because of climate change, with a lack of long-term studies on tick-borne pathogens in South Korea. To understand the epidemiological characteristics of tick-borne diseases, the monthly distribution of field ticks throughout the year was studied in South Korea between May 2014 and April 2018 in a cross sectional study.

We report the results of field operation of TELEACE system between Kyung-Pook National University Hospital and Ul-Jin Goon Health Care Medical Center from December, 1990 to September, 1991, which had been operated as a kind of Integrated Services Digital Nework projects by KOREA TELECOMMUNICATION Inc. Ul-Jin Goon Health Care Medical Center transmitted 414 plain radiographs to our hospital in speed of 9600BPS. Each image was composed of 1024X1024 pixelsX8 bits/pixel. In our hospital, the image files were displayed on high resolution monitor (1280×1024 pixets). Text files of image interpretations were transmitted to the health care medical center. The two radiologists who had interpreted the transmitted images, went to the health care medical center and read radiographic film with blind test method. We obtained the following results: false negative rate of 6.3%, false postitve rate of 2.4%, mean sensitivity of 81.4%, mean specificity of 96.3%, and mean accuracy of 91.3%. In predictive value of 0.05, there was no significant difference between results of these two types of radiographs. In conclusion, TELEACE system was valuable to the clinicians isolated from services of radiologists.

Radiologic chain cystourethrography for stress urinary incontinence (SUI) has several disadvantages including the risk of excessive radiation, the time required for the test, and the discomfort of the patients. Nowadays it is widely accepted that transrectal ultrasonography for evaluating bladder and urethra provides similar information about SUI comparing with the conventional radiographic examination. We evaluated the effectiveness of transrectal ultrasonography in the diagnosis of SUI in 30 women with SUI and in normal 20 women as a control. The results of evaluation were as follows: 1. Mean age was 52.9 in SUI group and 48.5 in control group, and mean parity was 2.8 in SUI group and 3 In control group. 2. According to the symptom grading by Stamey, 8 patients (27%) were Grade I and 22 (73%) were Grade II. 3. The mean value of posterior urethrovesical angle (PUVA) at resting state was 139 +/- 14.7 degrees in control group and 145 +/- 15.2 degrees in SUI group (p>0.05). 4. The mean value of PUVA at strain state was 146 +/- 7.9 degrees in control group and 169 +/- 12.1 degrees in SUI group (p<0.05). 5, Bladder neck descent was 7.3 +/- 2.7 mm (mean+/-SD.) in control group and 13.7+/-6.2 mm in SUI group (p<0.05). 6. Diagnostic criteria of SUI in transrectal ultrasonography are more than 149.5 degrees in PUVA at strain state, and more than 9.1 millimeter in bladder neck descent. 7. Sensitivity and specificity of transrectal ultrasonography in the diagnosis of SUI were 86% and 80% in PUVA at strain state, 80% and 80% in bladder neck descent, respectively. 8. There was significant change of transrectal ultrasonographic finding in pre and post-bladder neck suspension (p<0.05). In conclusion, transrectal ultrasonography is simple, non-invasive, not shameful, and free of radiation, so might be a useful diagnostic method in female SUI.

A clinical observation was made on 261 cases of transurethral resection of benign prostatic hyperplasia (TURP) by the same operator, admitted during the period of 10 years from January 1984 to December 1993. The objective cases were divided by every 50 cases into 5 groups, and the operation results were compared in each group respectively. The results showed the tendency of increasing weight of resected prostatic tissue and decreasing operating time, consumed time for the resection of l gm of prostatic tissue, blood loss during operation, duration of postoperative gross hematuria and incidence of postoperatively complicated cases, as experiencing more TURP cases. The operation results were markedly improved and stabilized after experience of 150 cases of TURP. Our study suggests that TUR technique of the operator is improving step by step by accumulating experiences of TURP and the expert and stabilized skillful technique will be achieved after experience of more than 150 cases of TURP but the improvement of TUR technique may be accelerated by aid of better TUR instrument and teaching system.

PURPOSE: To investigate the efficacy of age, International Prostate Symptom Score(I-PSS), quality of life(QOL) score, various parameters obtained by transrectal ultrasonography(TRUS) as predictors of the onset of acute urinary retention in patients with benign prostatic hyperplasia(BPH). MATERIALS AND METHODS: From January 1996 to December 1997, 101 men(mean age 70years, range 52-92) with symptoms of BPH were enrolled in this study. Among them, 36 patients had suffered from acute urinary retention. TRUS was used to calculate the total prostate(TP) volume, the transitional zone(TZ) volume, the transitional zone index(TZ index=TZ volume/TP volume). To compare the usefulness of various indices, the area under the receiver-operator characteristic(ROC) curve was calculated for each index. RESULTS: There were significant differences in age, TP volume, TZ volume, TZ index between patients with and without acute urinary retention, but no significant differences in I-PSS and QOL score. In patients with acute urinary retention, the area under the ROC curve was 0.911 for the TZ index, 0.892 for the TZ volume, 0.769 for the TP volume and 0.660 for the age. CONCLUSIONS: The TZ index is a useful predictor of acute urinary retention in patients with BPH and may be a useful parameter for decision of surgical intervention.
