A patient had total occlusion of the left main coronary artery that was proved by coronary arteriography. Patients with total occlusion of the left main coronary artery have a varying clinical presentation and may have prolonged survival. In patients with good collaterals, left ventricular function may be preserved. This report reveiws the clinical and angiographic findings of a patient with occlusion of the left main coronary artery with symptoms of unstable angina pectoris but without congestive heart failure or EKG evidence of myocardial infarction.

PURPOSE: In order to evaluate microstructural changes after shock wave exposure, gross, light microscopic and transmission electron microscopic findings were analyzed with rabbit gallgladders. MATERIALS AND METHODS: A preliminary study(2 rabbits) was performed to determine the dosage intensity of shock waves needed to inflict damage, using a EDAP LT 01 piezoelectric extracorporeal shock wave Iothotriptor. The gallbladders of three different groups of rabbits were given shock waves of various intensity. A storage value of 100, 50, 25 at rate of 20/sec under 80% power were given to group I (4 rabbits), group II( 4 rabbits), and group III(3 tabits), respectively. The rabbits were sacrified 6--12 hours later. RESULTS: The observed pathologic changes in the transmission electron microscopy were vaculization of cytoplasm and swelling of epithelial cells with dilatation and structural alteration of intracellular organelles, especially endoplasmic reticulum. Cell membrane rupture and necrosis were observed at the markedly affected area. The structural changes of intracellular organelles were minimally found at a storage value of 25. However, above pathologeic changes with dilatation and structural alterations of endoplasmic reticulums were more profund at value of 100. CONCLUSION: Early histologic changes induced by shock waves are dose dependent and the findings of cellular damage caused by ESWL might be explained as above.

The schwannoma is a benign neoplasm originating from Schwann cell. Solitary nerve sheath tumors such as benign schwannomas arising in the pelvic retroperitoneum are infrequently reported. Those tumors can indeed be misdiagnosed for other more common conditions both clinically and instrumentally. We report a very rare case of a benign retroperitoneal pelvic schwannoma of the obturator fossa, which was incidentally found and misdiagnosed as adnexal mass preoperatively in fifty one-years-old postmenopausal women.

BACKGROUND: The angiotensin-converting enzyme inhibitors have been found to be safe and efficacious in the treatment of essential hypertension. Fosinopril is the first angiotensin-converting enzyme inhibitor from a new class of agents containing phosphorus. This drug is known to be metabolized to almost and equal extent by the hepatic and renal pathways. METHODS: This study was performed to investigate the efficacy and safety of oral fosinopril, a new class of phosporus-containing angiotensin converting enzyme inhibitor, on essential hypertension. A single daily dose of 10mg to 20mg fosinopril was administered in 21 hypertensive patients with diastolic blood pressure in the range of 95mmHg-115mmHg while off all other anti-hypertensive agents for 10 weeks. Blood pressure and heart rate were measured every 4 weeks. The complete blood count, blood chemistry by SMA-12, serum electrolytes and urinalysis were performed at 12th week of therapy. RESULTS: 1) Baseline systolic and diastolic blood pressures after 2 weeks of placebo at sitting position were 158.8+/-15.7 and 99.4+/-6.3mmHg respectively. There was a statistcally significant reduction of blood pressure after 4 week treatment of fosinopril which was maintained up to 12 weeks of follow-up(158.8+/-15.7-99.4+/-6.3mmHg vs 139.3+/-18.2/86.6+/-10.3mmHg, p<0.05). 2) The proportion of responders defined by diastolic blood pressures less than 90mmHg or decline more than 10mmHg at 4, 8 and 12 weeks after treatment with fosinopril were 90.5, 95.2, and 95.2% respectively. 3) THere were no significant changes in blood chemistry, serum electrolytes, hematologic findings and heart rate over the treatment period. 4) Three patients experienced severe non-productive cough that required to discontinue the medication. CONCLUSION: In patients with mild to moderate hypertension, once-daily fosinopril(10mg and 20mg) provided significant anti-hypertensive effects without serious side effects. The 10mg dose was effective in majority of patients and may be considered as a starting dose.

BACKGROUND: Cicletanine bydrochloride is a newly developed anti-hypertensive agent. The presence of a furopyridine group characterizes its uncommon chemical structure as an antihypertensive molecule. This clinical trial was performed to confirm the efficacy and safety of cicletanine for the treatment of hypertension as a monotherapy. METHODS: In order to investigate the efficacy and safety of oral cicletanine, a now class of antihypertensive durgs, the furopyridines, on essential hypertension, a single daily dose of 50mg to 100mg cicletanine was administered in 46 hypertensive patients with diastolic blood pressure in the range of 95mmHg-115mmHg. The patients were asked to cut off other anti hypertensive agents for 10 weeks prior to this clinical trial. Blood pressure and heart rate were measured every 4 weeks. The complete blood count, blood chemistry done by SMA-12, serum electrolytes and urinalysis were performed at the 12th week of therapy. RESULTS: 1) Baseline blood pressures after 2 weeks of placebo at sitting and standing positions were 158.7+/-16.1/102.9+/-6.2 and 148.7+/-14.5/102.7+/-6.7mmHg, respectively. The overall slope which represents the tendency of blood pressure decline over the treatment period with cicletanine for all the patients in each position are as follows ; -0.726(SE : 0.150) for sitting systolic blood pressure(BP), -0.390(SE : 0.080) for sitting diastolic BP, -0.214(SE : 0.183) for standing systolic BP and -0.341(SE : 0.139) for standing diastolic BP. 2) The slope of sitting systolic BP line in cicletanine 100mg treated group was significantly stiffer than that of cicletanine 50mg treated group(-0.445 vs -1.021, p=0.0336). 3) There were no significant interval changes in heart rate over the treatment period. 4) There were no significant interval changes in blood chemistry, electrolytes, hematologic findings and urinalysis over the treatment period. 5) Several side effects were observed in six patients(epigastric discomfort in 4, easy fatigue and insomnia in one patient, respectively). CONCLUSION: Treatment with cicletanine was well-tolerated and the incidence of side effects was relatively low. Because of its unique anti-hypertensive mechanism and moderated antihypertensive effects, cicletanine may be well suited in the treatment of hypertension combined with other classes of antihypertensive agents.

We retrospectively evaluated the 20 patients who underwent the Raz operation for stress urinary incontinence. In the degree of severity, 4 cases were in Stamey grade I, 14 cases in Stamey grade II and 2 cases in Stamey grade III. Posterior urethrovesical angle(PUVA) and Urethral inclination angle(ULA) on lateral cystourethrogram were measured preoperatively and postoperatively. Preoperative PUTA and ULA were increased as the grade was higher, but postoperative PUVA and ULA were returned to normal range. The overall success rate were 90% and complications were minima1. We think that Raz technique for stress urinary incontinence is safe, reliable and low morbidity procedure.

Coarctation of aorta is a rare cause of secondary hypertension, and premature death will occur if no appropriate treatment is given. The only effective treatment was surgery before 1980, but restenosis was frequent. Several works on percutaneous transluminal angioplasty of the disease were reported. In patients with previously operated recoarctation, there is no doubt that balloon angioplasty is now the first choice of the therapy because of the surgical risks of reoperation. Nevertheless, there has still been some controversy regarding the application of this therapy to native coarctation, because of the potential risk of aortic disruption and the high incidence of restenosis. There have been some clinical reports of successful stent implantation for coarctation without major complications since 1991. We report on our experience with balloon-expandable stent implantation for native coarctation of the aorta in a 23-year-old man with congenital mitral stenosis. Aortogram showed a coarcted aortic segment of 3 mm in diameter and 25 mm long just distal to the left subclavian artery. The peak systolic pressure gradient across the coarctation before stent implantation was 100 mmHg. Stent implantation was performed with 14 X 40 mm balloon with Palmaz P308 stent. The peak systolic pressure gradient decreased to zero and the diameter of the coarctation of aorta increased to 14 mm after stent implantation immediately. The patient tolerated well and no significant complications were encountered during the procedure.
