From July 1988, open heart surgery was performed on fifty adults utilizing the pulmonary artery vent instead of conventional venting methods. The open heart procedures included were twenty coronary artery bypass grafitings(CABG), ten mitral valve replacements(MVR), ten aortic aneurysms(DA), and three ventricular septal defects(VSD). To determine the effectiveness of the pulmonary artery venting, non-cardiotomy procedures(CABGs') were classified into satisfactory, ordinary and poor group in terms of the degree of chamber dilatation throughtout the entire period of the operation. Again, cardiotomy procedures were categorized as degree 0, I, II, III and IV according to the clearness of the operative fields. Out of the twenty non-cardiotomy procedures, 17 cases(85%) were fallen into the satisfactory group, while the remained three cases into ordinary group. The degree of satisfaction, in cardiotomy procedures, was III or IV in patients having mitral valve replacement, aortic valve replacement, double valve replacement or dissecting aneurysm repair, and it was I or II in patients having ventricular septal defect repair, on the other hand. There was neither bleeding complication nor stenosis on the vent site. There was only one suspicious perfusion defect on routine postoperative perfusion lung scan. The study demonstrated that venting the pulmonary artery was very helpful in most of the procedures, because it was easy to reach, removal of the vent cannula was safe and simple and complications were trivial.

In a world, ocular infection of Pseudomonas has been found in premature infants. This is so serious that corneal perforation and panophthalmitis are developed. And septicemia is developed. In these days, hospital infection due to pseudomonas tends to increasese. We experienced one case of pseudomonas dacryocystitis in a normal full term infant. At first, we diagnosed it as a blenorrhea neonatorum due to pseudomonas infection. And the smear of vagina of his mother was examined by Gram stain and culture. But, pseudomonas was not found. So, we considered that it was because of hospital infection. The patient was treated with carbenicillin 400 mg/day intramuscularly and 0.5% chloramphenicol solution everyone hour topically for 2 weeks. During this time there wa.s no improvement. After then we found obstruction of nasolacrimal ducts and performed probing once. After that this case was cured.

Extracorporeal shock wave lithotripsy(ESWL) is becoming treatment of choice for most upper tract calculi, and especially EDAP made piezoelectric E. S. W. L. can treat kidney, upper ureter and lower ureter stones. We present the results of 245 consecutive treatments performed between May, 1987 and February, 1988 with piezoeletric shock wave lithotriptor. 1. The oldest patient was age of 78 and the youngest patient was age of 15 and there was no contraindication due to other systemic disease. 2. No anesthesia were required and only narcotics were given for pain that induced from shock wave, but one, 18 years old female with renal stone was treated with ketamine. 3. Response rate revealed that complete response was 174 cases (71%), partial response was 63 cases (25.7%) and non-response was 8 cases (3.3%). 4. In complete response cases, average requirement of shock wave storages were noted that renal stone was 323, upper ureter stone was 562 and lower ureter stone was 377 and then the shock wave storage was increase depend upon the location of the stone, such as kidney, lower ureter stone and upper ureter stone in priority. 5. Staghorn calculi, multiple renal stones, caliceal diverticular stones, renal stones with migration into the ureter while treatment, impact ureter stones, ureter stones with larger than 2.5 cm and obesity were poor response factors. 6. We adopted push up (9 cases), double J stent (6 cases), stone basket (6 cases), URS.(2 cases) and nephrostomy (1 cases) as auxiliary procedure. 7. Chemical composition of treated stones were that calcium oxalate and phosphate mixed stone8 were 50.6%, calcium oxalates 33.5%, struvites 10.5%, uric acid 3.9% and calcium phosphate 1.3%. 8. We experienced 11 cases (4.4%) of complications: 5 cases of stone street, 3 cases of post ESWL flank pain, 1 case of high fever, 1 case of sepsis and 1 case of perirencal hematoma. 9. As a result, we suggest that we should consider stone size, location, situation of patient and history of stone surgery for good effectiveness from treatment with E.S.W.L.

A basic problem in evaluating upper urinary tract gross hematuria is the large number of diagnostic possibilities. The causation may be suspected after the initial history and physical examination, and can be confirmed with appropriate studies. We have retrospectively studied of 60 patients who confirmed upper urinary tract hematuria through the cystoscopy in period from Oct. 1971 to Dec. 1987. We have performed relatively precise clinical studies such as urinalysis, urine culture, urine cytology, blood clotting disorders, intravenous pyelography, renal arteriography and others and then we have obtained following results. 1. Disease distributions Calculous disease 12 cases (20.0%) Malignant disease 11 cases (18.3%) Vascular disease 7 cases (11.7%) Glomerulonephropathy 4 cases ( 6.6%) Unexplained hematuria 2l cases (35.0%) etc. 2. Cystoscopy, intravenous pyelography and renal arteriography are valuable essential procedures for diagnosis of upper urinary tract bleeding. 3. Cystoscopy, intravenous pyelography and angiography will bring the percentage of patients with a clear diagnosis up to about 70 per cent, especially excretory urography and cystoscopy must always be done.

This review examines the critical issues of declining total fertility rates (TFRs) and aging populations in East Asia with special focus on South Korea. It provides a comprehensive analysis of TFR trends, aging demographics, and the policy responses of these nations to the low-fertility crisis. This study highlights the intricate tapestry of the factors contributing to these demographic shifts, including economic, social, and cultural influences. It also examines the effectiveness of various prenatal policies implemented across these countries, offering insight into their successes and limitations. Furthermore, it explores the role of immigration as a potential solution to the structural challenges posed by low birth rates. This review underscores the importance of multifaceted strategies for addressing the complex demographic challenges faced by South Korea.
