Clinically, the Rh blood group system is important since Rh antibodies are readily induced by transfusion or pregnancy in individuals negative for the antigert and may cause hemolytic reactions or hemolytic disease of the newborn. Since the D antigert is strongly immunogenic, donors and patients are routinely typed for D status and patients are generally given D compatible blood. But under several circumstances such as spontaneous agglutination of red blood cells coated with immunoglobulin, antisera with additives may cause false positive results in test using high-protein reagents. And facton in the patient' s own serum may also affect the test, since unwashed red blood cells suspended in their own serum or plasma are frequently tested. Therefore, manufacturers and American Association of Blood Banks(AABB) recommend that the Rh(D) control test with Rh(D) control reagent which contains the same additive present in high-protein anti-D except for the anti-D. This study was undertaken to evaluate the usefss of the Rh(D) control test in Korea where Rh(D) negative population is small. Red blood cells from 1115 in-patients and 468 out-patients at Korea University Medical Center were employed in Rh(D) typing and Rh(D) control test in parellel. 1580 cases are Rh(D) positive and 3 cases were Rh(D) negative. No agglutination was observed with Rh(D) control test. Though AABB and manufacturers recommended that the Rh(D) control test should be done in parellel with Rh(D) typing test, the authers concluded that there were no need to run the Rh(D) control test in Korea.

Korean Journal of Urology 2001;42(6):589-593
PURPOSE: The aim of the study was to evaluate the clinical outcome and complications of tension free vaginal tape (TVT) procedure for the surgical treatment of female stress urinary incontinence. MATERIALS AND METHODS: Between April 1999 and May 2000, 41 women with stress urinary incontinence underwent TVT procedure. Preoperative evaluation included questionnaires study, physical examination, one hour pad test and urodynamic study. Postoperative clinical outcome, patient's satisfaction and complications were checked after 3-months. RESULTS: The mean age of patients was 51.6 years (range 40-76) and mean hospital stay 2.1 days (range 1-10). The mean follow-up period was 9.9 months (range 3-15). Thirty six patients (87.8%) were cured, 2 patients (4.9%) were improved. Two of 3 patients with failed operation who developed postoperative urge incontinence had grade III cystocele. Five bladder perforations and 1 obturator nerve injury occurred. The abdominal leak point pressure (LPP) increased from 50.6cmH20 to 110.8cmH2O, detrusor pressure of maximal flow rate (Pdet.Qmax) increased from 15.8cmH2O to 28.6cmH2O and maximal flow rate (Qmax) decreased from 32.8ml/s to 22.5ml/s after operation. CONCLUSIONS: The TVT procedure is an effective and feasible surgical treatment for female stress urinary incontinence. However, in patients with grade III cystocele, postoperative urge incontinence may develop after the procedure. Since TVT procedure involves securing the mid-urethra, urinary obstruction may also occur, necessitating the need for continued follow-up as well as a careful comparison with other sling procedure.

The present study was aimed at investigating the effect of cyclosporine A (CsA) on the renal renin-angiotensin systems. In rats chronically treated with CsA, the intrarenal expression of various genes of the renin-angiotensin system was assessed by Northern blot analysis. Along with the increases in plasma and renal renin activities, chronic CsA-treatment differentially affected the renal expression of renin-angiotensin system. The treatment with CsA for one week did not significantly alter the expression of either type 1 angiotensin II receptor (AT1A) or angiotensinogen gene, but increased the renin mRNA level. The three-week-treatment caused increases in the expression not only of renin but also of AT1A and angiotensinogen genes. Supplementation with L-arginine kept the expression of renin mRNA normal in the one-week-treated, but failed to prevent the alterations of the gene expression in the three-week-treated. Feedback control among components of the renin-angiotensin system also influences angiotesinogen. In the liver, the expression of angiotensinogen mRNA was decreased by the CsA-treatment for either one- or three-weeks. In conclusion, chronic CsA-treatment is associated with a differential expression of various genes for the renin-angiotensin system. L-Arginine may be effective in maintaining the normality of renin-angiotensin system only during early period after beginning the use of CsA.

PURPOSE: As the number of children who attend child care centers has increased, concerns has increased about the effect of child day care on childhood illness. This study was conducted to examine the relationship between experience in child care and common infectious diseases in children under 5 years of age. METHODS: Data were collected by surveying 1,000 respondents with children under age 5 through online interviews using a structured questionnaire. The contents of the survey were composed of demographic characteristics, child care facilities usage, experience in infectious diseases, and immunization status. RESULTS: Among the 1,000 children <5 years of age, 78.5% attended a child care facility. Rates of common communicable illnesses were higher in children in child care than for children reared exclusively at home. The predominant communicable diseases which the respondents' children experienced, in order of decreasing frequency, were gastroenteritis (47.1%), otitis media (41.8%) and pneumonia (19.1%). The immunization rate of vaccines that are not included the national immunization program (NIP) (Haemophilus influenzae type b vaccine - 76.6%, hepatitis A vaccine - 63.3%, pneumococcal vaccine - 59.4%, rotavirus vaccine - 43.1%) was lower than that of the NIP vaccines (90.4%). CONCLUSION: Children in child care experience more bouts of common infectious disease, so nationwide policies to prevent or to control the spread of infectious agents in a child-care should be available and appropriate immunization should be emphasized as the most effective method for the control of infectious disease for children.

Once splinter hemorrhage can be considered as a pathognomonic sign of subacute bacterial endocarditis. But it can also be associated with a variety of systemic disorders that increase capillary fragility or primary nail bed involvement in dermatologic disorders. The cause of splinter hemorrhage can usually be established by careful history and physical examination. We report a case of 33-year-old man with splinter hemorrhages, who had polycythemia vera.

PURPOSE: This study was designed to identify the possible mechanism of insensitivity of DU145 prostate cancer cells to the transforming growth factor (TGF)-beta1-mediated growth inhibition. MATERIALS AND METHODS: DU145 cells were treated with 4, 40, 100 pM TGF-beta1 for 3, 6, 9 days. Initially we performed the growth assay. After that, we analysed the change of cell cycle using fluorescence flow cytometry. At each time point, Western blot analysis with cell pellets was performed to investigate the change of expressions of epidermal growth factor(EGF), TGF-alpha, EGF receptor(EGFR) and TGF receptorII(TbetaR-II) proteins. RESULTS: The growth rate of TGF-beta1-treated cells was initially suppressed, but over time returned to control level. Flow cytometric analysis revealed that TGF-beta1-treated cells showed an increase in apoptotic/G1 phases, and concurrent decrease in S, G2/M phases until 6days. On day 9, however, TGF-beta1-treated cells showed a persistent increase of apoptotic unclei in spite of recovery of apoptotic/G1, S and G2/M phases. Western blot analysis showed that the intensity of EGF or TGF-alpha band decreased in dose-sependent manner on day 6. However, the intensity of each band increased up to the control level on day 9. the expression of EGFR or TbetaR-II protein did not change after treatment of TGF-beta1. CONCLUSIONS: these results suggest that EGF and TGF-alpha sould mediate in part the escape fron the inhibitory effect of TGF-beta1 in DU145 cells.

Diffuse aspiration bronchiolitis is defined as a clinical entity characterized by a chronic inflammation of bronchioles caused by recurrent aspiration of foreign particles. Clinical symptoms are bronchorrhea, bronchospasm, and dyspnea, and chest radiographs show the presence of regional or disseminated srnall nodular shadows and hyperlucency. Chest CT should help in detecting diffuse nodular shadows of bronchiolitis. Pathologic findings of diffuse aspiration bronchiolitis are characterized by localization of chronic mural inflammation with foreign body reaction in bronchioles. Recurrence of small amounts of aspiration might play an important role in the pathogenesis of diffuse aspiration bronchiolitis. We report a case of diffuse aspiration bronchiolitis in a 4-month- old female infant who had recurrent aspiration due to dysphagia and presented with recurrent fever, dyspnea and wheezing. She showed typical radiologic and histologic findings compatible to diffuse aspiration bronchiolitis. She was improved with treatment of nasogastric tube feeding. We emphasize the importance of recognizing this disease entity and differentiating it from pulmonary diseases associated with bronchospasm. (J Korean Pediatr Soc 2000;43:842-845)

8.Transitional Cell Carcinoma of the Bladder in Patients 40 Years Old or Less.
Korean Journal of Urology 1988;29(6):903-908
Transitional cell carcinoma(T. C. C) of the bladder is the most common neoplasm of the urinary tract, but it occurs infrequently in younger patients. T. C. C. of urinary tract under the age of 40 is often thought to be a milder form than in older age group. However the literature provides little information on this and is contradictory. So, a total of 28 patients 40 years or less presented with T. C. C. of bladder between Jan., 1968 and Dec., 1987 was followed up and analyzed. It would appear that bladder carcinoma in patients 30 years old or less has a favorable prognosis, but disease occurring when the patient is 31 to 40 years old has a much worse prognosis and is not different from that affecting the older age group.

We experienced a case of primary aldosteronism due to adrenal adenoma. The patient was 45-year old female, whose main complaints were weakness, headache, and fatigue. By use of abdominal CT scan, ultrasonogram, adrenal angiogram and by result of clinical laboratory findings, we conculuded the diagnosis of adrenal adenoma, and confirmed it by surgical and pathologucal findigs. The clinical sympyoms disappeared after left adrenalectomy, and laboratory findings of renin, aldosterone, electrolutes were normalized but hypertension persisted, so she has been managed by antihypertensives.

This is a report of clinical study on the 63 patients of symptomatic urinary tract infection who were hospitalized at the Department of Pediatrics in Kangnam General Hospital during the period between the May of 1989 and the September of 1992. The observation results were as follows: 1) The frequency of urinary tract infection (UTI) was the highest in children under the age of one year (66.7%). 35 patients were male, while the other 28 were female. The ratio of male and female patients was 1.25:1. 2) Fever was observed in most of the cases. Systemic nonspecific manifestation was predominant in the infancy and early childhood, whereas local symptom of UTI was predominant in the late childhood. Among the 35 male patients, 32 cases were phimoses. As for the other 3 cases, Phimoses were not identified. 3) E. coli had the most frequency (65.3%), followed by Klebsiella, Enterobacter, Pseudomonas in descending order. 4) In the vitro antimicrobial susceptibility test, Gram negative organisms such as E. coli Klebsiella, Enterobacter were sensitive to cefotaxime, amikacin, and ampicillin/sulbactam. Meanwhile, Gram positive organisms such as Staphylococcus, Enterococcus were sensitive to vancomycin and cephradine. 5) The renal ultrasonography test was performed for 59 patients, 13 cases of whom showed abnormal findings. 6 cases out of the 13 abnormal patients had hydronephrosis. 6) DMSA renal scan was performed for 40 patients within 2 months of an acute pyelonephritic attack. Signs of pyelonephritic change were found in 18 patients. DMSA scan was repeated 4~12 months later in 4 of these patients. This showed renal cortical scarring in all patients. 7) Voiding cystourethrographic findings in 38 patients showed vesicoureteral reflux in 13 patients. 8) We performed urine culture again after 48 hours from the beginning of therapy and 85.5% of the cases became sterile. 9) The recurrent percentage of UTI was 23.8% with the ratio of 1:1.5 between male and female. Most of the patients were clildren under the age of one year. 10) Operations were made on two cases showing the increase of reflux during the follow-up of unilateral Grade ll and Grade 3 reflux, respectively. Operations were also performed on other two cases with bilateral Grade IV reflux. All the cases were good after the operations. In the meantime, as for another two cases having the right reflux of Grade lland the bilateral reflux of Grade lll, the refluxes were able to be reduced by prophylaxis only, in the course of following up.
