PURPOSE: Invasive determination of cardiac output (CO) is possible via a pulmonary artery catheter but catheter implantation has risks. Clinicians can assess CO safely using a non-invasive cardiac output device such as a commercially available doppler system (ultrasonic cardiac output monitor, USCOM, USCOM Ltd, Australia) or using impedance cardiography (ICG). The purpose of this study was to investigate the consistency of hemodynamic measurements between ICG and USCOM in shock patients. METHODS: From June 2007 to October 2007, we prospectively evaluated 21 patients with shock, who visited our emergency center. We measured CO and systemic vascular resistance (SVR) using ICG and USCOM on arrival, and at 30, 60, 90, and 120 minutes. RESULTS: The mean difference in CO between ICG and USCOM was 1.08+/-2.13 L/min. The percent limits of agreement (LOA) were -60.0 to 84.7% between ICG and USCOM. The correlation coefficient for CO between ICG and USCOM was 0.76 (p<0.01). CO values measured by ICG and USCOM were 4.3+/-1.7 vs 5.9+/-3.9 initially, 4.8+/-2.2 vs 6.0+/-3.9 at 30 min, 4.3+/-1.6 vs 5.1+/-2.9 at 60 min, 4.2+/-1.6 vs 4.9+/-2.7 at 90 min, and 4.1+/-1.6 vs 5.0+/-2.9 at 120 min, respectively. Statistical significance was observed within each modalities (p=0.03) but we did not find statistical significances between the two modalities. SVR (dynes*sec/cm5) values were measured by ICG and USCOM on arrival, and at 30, 60, 90, and 120 minutes. No statistical significance was seen within and between study groups. CONCLUSION: ICG and USCOM do not show clinically acceptable agreement.

Leiomyoma is rare. Most of patients present with urinary tract infection, hematuria, dyspareunia, or complaint of mass. A case of leiomyoma on urethrovaginal septum in a 36 years old female was presented. The presenting symptom was a protruding mass at the anterior vaginal wall The mass was removed surgically and confirmed as a leiomyoma pathologically.

PURPOSE: The aim of this study is to identify postoperative renal function and preoperative factors that can predict renal impairment after living donor nephrectomy. MATERIALS AND METHODS: We studied 172 patients undergoing living donor nephrectomy for kidney transplantation (115 males, 57 females). We analyzed the renal function measured by serum creatinine and the 99mTc- diethylenetriamine penta-acetic acid (DTPA) renal scan. Using a univariate and multivariate analysis, we also analyzed multiple independent variables for the remaining renal function following living donor nephrectomy, such as serum creatinine, glomerular filtration rate (GFR), age, sex, duration of follow-up, blood pressure, body mass index (BMI), serum calcium, serum phosphate, serum uric acid. RESULTS: The mean age of the donors was 34 years, and the mean duration of the follow-ups was 11 months. The mean serum creatinine at 11 months after kidney donation was increased compared to preoperative creatinine (1.26mg/dl vs. 0.93mg/dl), and significantly greater in the males than in the females (1.36mg/dl vs. 1.09mg/dl). Mean GFR measured by the 99mTc- DTPA renal scan at 11 months after kidney donation was 69.2 ml/min/ 1.73m2 and similar for men and women (72.3ml/min/1.73m2 vs. 68.3ml/ min/1.73m2). The univariate analysis showed that preoperative creatinine was significantly associated with postoperative creatinine only (p<0.001), and age and sex were associated with the change in creatinine (p=0.046, p<0.001). The univariate analysis also showed that preoperative GFR and age were significantly associated with postoperative GFR (p<0.001, p<0.001), and age was associated with compensatory change in GFR (p= 0.008). The multivariate analysis showed that preoperative GFR was the primary predictive factor of postoperative GFR (r=0.73, p<0.001), and age was an independent secondary predictive factor (r= 0.67, p<0.001). CONCLUSIONS: These results suggest that postoperative renal function has been preserved in kidney donors, and preoperative creatinine, preoperative GFR, and age at donation were the important predictive factors of renal function after living donor nephrectomy.

5.No-incision pubovaginal suspension for stress urinary incontinence: 15 cases.
Korean Journal of Urology 1991;32(2):289-293
Fifteen stress urinary incontinence patients were treated using the modified endoscopic suspension of the bladder neck that eliminates all incisions during the period from January 1990 to December 1990. The average operation time was 26 minutes and the mean days of urethral Foley catheter removal were 3.9 days operation. Two point three days were required to restore the normal voiding pattern. Of 15 patients treated. 1 failure occurred, for an overall success rate of 93%. There had been no significant complications. Therefore, no-incision pubovaginal suspension was simple and effective means treating stress urinary incontinence.

PURPOSE: To determine whether prostate-specific antigen density(PSAD) and transition zone prostate-specific antigen density(TZ-PSAD) can predict the clinical response of patients with benign prostatic hyperplasia(BPH) to alpha-adrenergic blocker(terazosin). MATERIALS AND METHODS: From January 2000 to June 2002, 202 patients with BPH who were treated with alpha-adrenergic blocker(terazosin) were enrolled in this study. The peak flow rate(Qmax) and the International Prostate Symptom Score(IPSS) were compared prior to and 3 months following medication. We analyzed total prostate volume(TPV), transition zone volume(TZV), transition zone index(transition zone volume/total prostate volume, TZI), PSAD(PSA/total prostate volume), and TZ-PSAD (PSA/transition zone volume) as predictors of the response to alpha-adrenergic blocker (terazosin). RESULTS: At 3 months following medication with terazosin, a statistically significant improvement was shown in the IPSS and Qmax. There was no significant correlation between pretreatment TPV, TZV, TZI and the percent change in the IPSS and Qmax. However, there was a significant negative correlation between pretreatment PSAD (r=-0.632, p<0.001), TZ-PSAD (r=-0.599, p<0.001) and the percentage change in Qmax, while there was a positive correlation between pretreatment PSAD (r=0.620, p<0.001), TZ-PSAD(r=0.604, p<0.001) and the percentage change in the IPSS. Using the receiver operating characteristic curves to compare PSAD and TZ-PSAD for IPSS, the areas under the respective curves were 0.867 and 0.874(cut-off values were 0.04 and 0.1), and for the Qmax, the areas under the respective curves were 0.876 and 0.873(cut-off values were 0.04 and 0.1). CONCLUSIONS: Patients with a lower pretreatment PSAD and TZ-PSAD responded better to alpha-adrenergic blocker than those with a higher pretreatment PSAD and TZ-PSAD. PSAD and TZ-PSAD were predictors of the response to alpha-adrenergic blocker (terazosin) in patients with BPH.

In May 1974, authors encountered a 37 year old Korean male who was suffering from very serious condition of acute abdomen. On exploratory laparotomy, a ruptured granulomatous mass in the proximal portion of the ileum showing extensive inflammatory and gangrenous changes was found and about 4 ft. long of the bowel was resected. From the honey-combed fibrous capsules in the mass, four plerocercoid larvae, spargana, measuring about 3 to 7 cm in lengths were extirpated. The patient had a past history of having eaten the raw flesh of a snake as a tonic about 7 months prior to admission. Four cases of intra-abdominal sparganosis reported previously in Korea and the present case were discussed briefly. Snakes and frogs in Korea are very important second intermediate hosts for the 1arva, Sparganum stage. It is most preferable that the habitual ingestion of the raw fleshes of them should be avoided in this country.

An outbreak of dermatosis occurred in a livestock fodder factory at Kyongju in May 1994. Authors conducted a questionnaire survey on 60 workers in the factory and a dermatologist examined their skin lesion. Authors also collected mites and identified them. The obtained results were summarized as follows; 1. Twentyeight cases of dermatosis were identified with attack rate of 46.7%. Attack rate was not different by department, age, sex, educational level and employment duration. Attack rate was 67.5% in productive worker and 5.0% in clerical workers (p<0.01) but was not significantly different between departments among productive workers (p>0.05). 2. Three cases among 28 dermatosis cases and one subject among 32 non-cases had a history of same dermatosis last year. Only one of dermatosis cases had a history of dermatosis among family members. History of other skin lesion and allergy was very rare in both cases and non-cases. 3. Skin lesions of the cases were rice-sized erythematous papules or vesicles with a central biting point. Onset date of dermatosis was between May 1 and June 10. Duration was from one day to more than 30 days. Skin lesion was most frequent at the back(75.0%). and also observed at the arms(64.3%). abdomen(60.7%), legs(57.1%), chest(32.1%) and neck (25.0%). Skin lesion was aggravated while workers are sweeping the floor(35.7%), working at the workplace(21.4%) and in bed at night(28. 6%). 4. Total l,637 mites were collected and identified into 3 suborder, 7 families and 17 species. Dermafophagoides farinae was most frequent Nnd most of the species identified were blood sucking mites. Authors concluded that the outbreak of dermatosis was brought about by mite-bites and grain beetle parasitizing Acarophenax tribolii was the most suspected species. Further studies to identify the specific species causing dermatosis and route of import are needed.

The present study was carried out to investigate the HHsAg in the normal skin, dis- eased skin and skin specimens of window period of HBsAg positive patients in their serum with normal liver function. This study was done by immunoperoxidase techniques using the monoclonal antibody to hepatitis E3 surface antigen and by electron microscopy. Immunoperoxidase staining was dane on twenty specimeris of normal skin Group .D twenty specimens of diseased skin (15 cases of dermographism, 2 cases of purpura, 1 case of follicuht,is and 1 cases of morbilliform eruption) (Ciroup II ) and three specimens of normal skin af window period (Group III ) of HBsAp positive patients in their serum. Twelve cases of Group I, eleven cases of Group IL (1(J cases of dremographism and 1 rase of purpura) and two cases of Group II were stained positively for HBsAg. Positive sites were keratinocyte of epidermis, sweat gland, blood vessel and hair follicle. Electron microscopy failed to reveal viral particle, The above resuts suggest the possibility of transmission of viral hepatitis B thraugh the skin and skin appendages.
