2.AVS(Audiovisual Stimulation)-Penogram.
Korean Journal of Urology 1988;29(3):459-469
In an effort to find more comprehensive and general diagnosis of erectile failure, we already have analysed 90 cases and reported the results. After that we added 199 more cases and performed a computer based analysis of total 289 cases in the dynamic changes of penile blood flow during natural physiologic erection after exposure to the audiovisual stimulation. The following results were obtained. 1. In normal volunteers, we were able to achieve uniform penogram findings in all cases with T.T.(Transit Time) ranging 1 to 3 minutes(mean 2.17 minutes), the EPT(Erection Persistent Time) over 30 minutes and no fluctuation phenomena after AVS. 2. Erectile failure group.(2.83 cases) (1) Group I.(108 cases; 38.2%). They demonstrated similar penogram features with the normal volunteers but EPT more than 5 minuets(mean 18.26 minutes) at least. most common causes were psychogenic origin(57 cases). (2) Group II.(175 cases ; 61.8%). Patients were showing abnormal penogram findings, and were divided into following 3 types. a) A type-Impossible type(10 cases ; 3.5%). They failed to show more than 2 fold increase in the maximal radioactivity after AVS when compared to the pre-stimuli level(mean 1.83 times). The underlying causes were identified to be arteriogenic and neurogenic. b) B type-Unstable type(124 cases ; 43.8%). They were unable to sustain erection due to fluctuation(mean 1.83 times). The underlying causes were psychogenic, vasculogenic and neurogenic origins. c) C type-Delayed type(41 cases ; 14.5%). They were showing T.T. more than 15 minutes(mean ; 23.71 minutes), and the underlying causes were arteriogenic, psychogenic and neurogenic origins. Based on these results, we have concluded that AVS-Penogram seems to the most appropriate diagnostic method for screening test and follow-up evaluation after vascular surgery. Through more clinical experience and investigation, and more comparison and analysis with other diagnostic methods, it will be a standard diagnostic approach in the future.

Hemophilia, a genetically determined disorder, can be divided into hemophilia A and hemophilia B. Hemophilia A, defined as a sex-linked recessive trait hemorrhagic disease of males characterized by a deficiency of factor VIII occurs about seven times more frequently than hemophilia B which is characterized by a deficiency of factor IX. The complications resulting from hemophilia occurs in virtually every system. This paper is concerned with a rare complication of hemophilia, iliacus hematoma with femoral neuropathy. On case of spontaneous hemorrhage of iliacus muscle with femoral neuropathy in hemophilia was decompressed through a small incision with sump drainage under cover of AHF(Anti-hemophilic factor) concentrated plasma cryoperecipitate followed AHF replacement therapy.

PURPOSE: To evaluate the early clinical results of lumbar microdiscectomy using minimally invasive tubular retractor (METRx-MD system, Medtronic Sofamor Danek, Memphis, TN), and to validate the merits of minimally invasive spinal surgery. MATERIALS AND METHODS: From April, 2003 to April 2004 we retrospectively studied a consecutive series of 45 patients who underwent lumbar microdiscectomy using minimally invasive tubular retractor. In all cases, minimally invasive approach using the tubular retractor were performed with a 2 cm sized paramedian incision. The following data were collected: clinical outcomes, operative time, intraoperative blood loss, need for blood replacement, time needed before ambulation, length of hospital stay, and complications. The clinical outcomes were assessed by the modified MacNab criteria. RESULTS: Minimally invasive tubular microdiscectomy was performed in 45 patients over a 12-month period with an average follow-up of approximately 8 months. The clinical outcomes assessed by MacNab criteria were excellent in 33 patients (73%), good in 10 patients (22%). The average operative time was 63 minutes (range, 35 to 95 minutes). The average blood loss was 62 mL (range, 50 to 110 mL). None of the patients needed blood replacement. With the exception of 2 patients, all patients could walk at the day of surgery. The average hospital stay was 2.3 days. None of the patients had dural tear, wound problem, or other complications. CONCLUSION: Lumbar microdiscectomy using tubular retractor can offer a useful modality for the treatment of lumbar herniated disc with the merits of minimally invasive spinal surgery. Further long-term, randomized, prospective investigations are needed to fully evaluate the impact of this technique.

In order to investigate the occurrence characteristics of cancer in terms of industry in Kwangju-Chonnam area, medical utilization records of industrial medical insurance corporations during the period of 1987 to 1988 were reviewed for the identification of neoplastic disease. The cases obtained from the medical records were followed up for the verification and to get additional information. Standardized incidence data were compared by occupational characteristics. Multiple logistic regression analysis was applied to analyze the difference of incidence or distribution of cancer as a whole or of some selected cancer. Total cases of cancer identified were 242 during the study period. Annual incidence rate was calculated as 123.1 per 100,000 person. The frequent types of cancer were cancers of stomach, liver, lung, colon and rectum, bladder and lymphoma in descending order. Employees of mine and other sand handling industries showed significantly higher risks for cancer of stomach and cancer as a whole. Employees of the transportation industry showed the higher risk for cancer of liver. Workers in small-sized industry (< or = 100) had a higher risk for cancer than who in large-sized industry (>100). These findings suggested the effect of occupational environmental exposure to cancer development.

7.A Study about Reliability of Radioisotope in Diagnosing Varicocele.
Korean Journal of Urology 1990;31(5):707-714
In order to consider the usefulness of radioisotope in diagnosing varicocele, a study was performed on 124 cases. Among them, 74 cases were diagnosed as varicocele, which included 16 cases of subclinical varicocele. Among 74 varicocele patients, 62 cases ( 83.8%) were diagnosed by varicocele index and 59 cases (79.7% ) were diagnosed by static image. A combination of the above two methods allowed 67 cases (90.5 %) to be diagnosed. 21 patients who had a high ligation of internal spermatic vein showed 11 excellent results, 6 good results and 4 poor results. Out of 10 patients with subclinical varicocele, there were 6 excellent results, 3 good results and 1 poor result and 9 patients showed improvement on postoperative semen analysis. There was no significant statistical difference in frequency of the testicular arterial insufficiency between the small varicocele group and the large varicocele group. Also, through scrotogram, it became known that semen analysis proved little help in aiding the diagnose of subclinical varicocele. In conclusion, 'Scrotogram proved very helpful in diagnosis and judging the results of operations of varicocele including subclinical varicocele.

This study was designed to answer the question; (1) How does the DNA ploidy pattern change in hepatocarcinogenesis? (2) How does the nuclear morphology change in hepatocarcinogenesis? Diethylnitrosamine(DEN) (16.5 mg per kg) was subcutaneously injected to female Sprague-Dawley rats(150~200g) by weekly interval for 30 weeks. DNA ploidy and parameters of nuclear morphology were measured by image analyser(IBAS 200, Kontron, FRG). The DNA ploidy pattern was divided into three basic patterns(diploid, polyploid, and aneuploid modes). In 8 cases of saline-injected control rats, the DNA histograms showed all polyploid pattern. Inhepatocyte nodules(hyperplastic nodules), DNA diploidy was the most frequent pattern, being followed by polyploid and aneuploid DNA patterns, contrast to hepatocelular carcinomas in which polyploid DNA pattern was most frequently noted being followed by diploid and aneuploid DNA pattern. Although the nuclei of hepatocytes in hepatocyte nodules and hepatocellular carcinomas were larger and more pleomorphic than those of normal hepatocytes, they were as same as those of normal hepatocytes in regard to nuclear hyperchromasia. DNA content, which was increased in hepatocarcinogenesis, was significantly related to the nuclear area.

9.Association Between Constipation-Predominant Irritable Bowel Syndrome and Dietary Habits of the Elderly Aged Over 65.
Journal of the Korean Geriatrics Society 2016;20(2):94-101
BACKGROUND: Irritable bowel syndrome (IBS) is one of the most common diseases of the digestive system, with a worldwide prevalence of approximately 20%. However, studies on constipation-predominant IBS in the elderly are scarce. Since Korea has the highest elderly population, with 38.2% of its population expected to be aged over 65 years by the year 2050, a study on the presence of IBS in this population is warranted. METHODS: In the present study, IBS was defined and classified according to the Rome III criteria. This study was performed by using the case and control method at the outpatient Department of Family Medicine and the health promotion center of a hospital in Gwangju. The questionnaire for the demographic characteristics and dietary habits was administered to 128 patients with IBS and 193 controls. RESULTS: Individuals who had a tendency of overeating for >3 days a week, compared to those who had a tendency of overeating for <2 days a week; those who had spicy food for >3 days a week, compared to those who had it for <2 days a week; and the time of meals showed statistically significant results. Meanwhile, the number and regularity of meals and having breakfast were not relevant factors. CONCLUSION: The weekly frequency of overeating and intake of spicy food as well as short time for meals are related to constipation-predominant IBS in the elderly aged above 65 years.

It is important to predict the prognosis of patient with cancer. Well known parameters predicting the prognosis are staged and degree of differentiation. Recently, the prognostic and diagnostic significance of silver-stained nucleolar organizer regions(Ag-NORs) and flow cytometric DNA analysis are introduced. This study aims to detect the diagnostic significance of Ag-NORs in breast lesions, and to correlate the number of Ag-NORs and cellular ploidies in breast carcinoma. In addition, the existence of heterogeneity according to the sample in the same patient is studied Sixty six paraffin blocks(two primary lesions and the two metastatic lymph nodes in 13 patients, and one primary lesion and one metastatic lymph node I 10 patients) of breast carcinoma, 30 paraffin blocks of fibroadenoma and 23 paraffin blocks of normal breast are studied. The numbe of Ag-NORs increase from normal breast(mean 1.45) through fibroadenoma(mean 1.60) to carcinoma(mean 2.43). It was significantly different between each lsions(P<0.0005). The number of Ag-NORs increased in the aneuploidy carcinoma than that in the euploidy one(P<0.05). But, there was difference between the number of Ag-NORs and DNA index according to the sample area in the same patient with carcinoma. In conclusion, the number of Ag-NORs is diagnostically significant in breast lesions and is correlated with cellular ploidies in breast carcinoma. In addition, Ag-NORs and cellular ploidies are heterogenous in the same patient.
