The incidence of giant condyloma acuminata of the penis is extremely rare. Although they are considered clinically malignant, the real possibility of malignant changes from them are controversial even among the investigators but cannot be entirely overlooked. Therefore, attention must be focused on this fact, in our conclusion. Two cases of malignancy of the penis which have apparently been transformed from giant condyloma acuminata of the penis are herein presented with review of related literatures. Case I: Sixty nine year old male patient complained of a fungating mass on the sulcus coronaris of the penis with ulceration and bleeding from the mass. Biopsy confirmed giant condyloma acuminata and subsequently circumcision and electrocoagulation were performed. Pathological specimen taken after 4 months because of the recurrence of the mass on the same region showed squamous cell carcinoma of the penis and amputation of penis was performed. Case II: Sixty eight old male patient complained of a growing mass and pain on glans penis. This patient also underwent circumcision and electrocoagulation according to the biopsy finding of giant condyloma acuminata. But 1 year later with recurrence of the mass on the same region, the pathological finding revealed squamous cell carcinoma of penis.

A clinical study was made on 117 cases of benign prostatic hyperplasia admitted to the Department of Urology, Chungnam University Hospital during the period from January 1974 to August 1982. The results were summarized as follows: 1. Common symptoms were dysuria (82.1%) and urinary retention (41.0%). 2. Gross or microscopic hematuria was noticed in 48 cases (41.0%). 3. The degree of prostatic enlargement by rectal palpation was not related to the severity of symptoms. 4. Pulmonary disease (19.5%) and cardiac disease (12.8%) were frequently associated with B.P.H. 5. Treatment consisted of suprapubic of retropubic prostatectomy in 94 cases, TUR in 7 cases and cystostomy in 10 cases. 6. Postoperative complications were urinary incontinence (34%), wound problem (9.7%), delayed bleeding (8.7%), and urinary tract infection (4.8%). 7. Mean weight of removed prostatic tissue was 31.3gm.

The study in the fild of medical instrument has been out of the interest by any the life scinetist in Korea. Especially the recent developments in the medical electromics are remarkable one. Authors planned this study to ascertain the possibility of setting up the thermistor thermometer with available accessories of demetic products including some specific foreign assembly parts. By proper use of the thermistor as one of the wheatstone bridge, we could detect the resistance variations due to the environmental temperature variance. The intensive care for the bridge circuit and compensation scheme was required. The calibration procedure adopted here makes it possible to read the current as the temperature. The temperature range was determined by the examination and construction of the graph of the resistance-temperature, the reduction of excessive current and self-heating of the thermistor were made. Renovation in response-velocity was under taken too. This electronic thermometer was designed and assembled by the circuitry developed in accordance with the maximum availability of domestic products with some foreign-made parts. The result of our experiment showed very stable function and proved to be the most promising item in the actual application as long as the thermistor is concerned.

This study aims to find factors that affect variations in cesarean section frequency rates among OBGY clinics in Metropolitan areas. The factors include patient, medical supplier characteristics and economic factors. This study is a cross-sectional analysis using health insurance delivery claims from July to December 2000 and files of the NHIC(national health insurance corporation). Multiple regression was used to analyze the dependent variable of cesarean section frequency rate at each clinic. The results are as follows : Cesarean section frequency rate is increasing in proportion to the number of the following patients : repeated caesarean section, disproportion, obstructed labour, fetal distress, emergency caesarean section and self-employed patients. There are geographic variations as well. Cesarean section frequency rates are higher in Inchon and Gyonggi province than in Seoul. The higher number of total delivery the clinic has, the lower rate of cesarean section it has. Clinics with high frequency rates in 1999 showed higher rates the next year. Further research is required to develop evidence based delivery modes and change strategies for increasing normal delivery and activating midwife clinics.

Fetal bilateral renal agenesis is a lethal congenital anomaly. An early and reliable prenatal diagnosis is extremely important as it may offer options for pregnancy termination as early as possible. The criteria for the ultrasonographic diagnosis of bilateral renal agenesis are severe oligohydramnios, nonvisualization of the bladder, and the empty renal fossa. However, severe oligohydramnios makes it difficult to diagnose the disease because of poor sonographic resolution. We present two cases of bilateral renal agenesis, one is diagnosed by ultrasonography after amnioinfusion at 24 weeks gestation, the other is diagnosed postnatally after term delivery.
