ABSTRACT

Congenital anomalies of the coronary artery are associated with various symptoms including syncope, myocardial ischemia, and sudden cardiac death. The abnormality depends on the adjacent structure and pathway of the coronary artery. Most patients with an anomalous left coronary artery that arises from a right coronary sinus of the valsalva have no symptoms and are usually diagnosed at autopsy. Therefore, their first symptom might present as sudden death, particularly when the left coronary arterial course is between the aorta and the pulmonary trunk. Symptomatic patients could be diagnosed early with an anomalous coronary artery, and the risk of fatal events could be decreased by surgical correction. Here, we report the case of 62-year-old male who experienced a first episode of syncope with an anomalous left coronary artery arising from the right sinus of the valsalva with a separate orifice from the right coronary artery. He is alive and in good health receiving medical treatment, and has had no medical events for over 2 years.

ABSTRACT

Atrial fibrillation (AF) is a relatively common cardiac arrhythmia that can have adverse consequences due to a reduction in cardiac output and thrombus formation. For patients hemodynamically unstable due to AF, we recommend urgent direct current (DC) cardioversion. The importance of an automated external defibrillator (AED) in the emergency medical field for this purpose is very high. In addition, the distribution rate of an AED in public health care is on the rise. We herein describe a patient whose chronic AF was converted to a sinus rhythm by defibrillation during an episode of sudden cardiac arrest (SCA) which consequently improved left ventricular systolic function. We have experienced the importance of active use of AED.

ABSTRACT

Amiodarone is an antiarrhythmic drug known to have adverse effects on multiple organs. Most studies have reported the side effects of the drug, which may result from rapid administrations or from long-term, high dosage administrations. However, toxicity issues have also been reported from patients administered with low doses of the drug for a long period of time. Here we report a case of an 82-year-old female who had shown symptoms and signs of pulmonary, hepatic, and neurotoxicity after taking amiodarone for 14 months in order to treat her atrial fibrillation without regular outpatient follow-up. We highlight the importance of the recommended evaluations, including lung, liver, and thyroid functions, as well as the neurological examinations in patients treated with amiodarone for a long period of time during regular follow-up.

ABSTRACT

BACKGROUND AND OBJECTIVES: Platelet-derived growth factor (PDGF) seems to be one of the most powerful factors associated with the proliferative process that occurs after percutaneous transluminal coronary angioplasty (PTCA), and leads to restenosis. Trapidil (Triazolopyrimidine), a potent inhibitor of PDGF, was shown to decrease restenosis after experimental balloon angioplasty. The aim of this study was to assess the effects of trapidil, on intimal hyperplasia, following coronary artery stenting, using volumetric intravascular ultrasound (IVUS) analysis. SUBJECTS AND METHODS: The patients were divided in 2 groups; Group I (n=14, age=53+/-8, male=11) received trapidil (600 mg) for 6 months, aspirin (200 mg) indefinitely and ticlopidine (250 mg) for 4 weeks, Group 2 (n=15, age=55+/-2, male=9) received aspirin (200mg) indefinitely and ticlopidine (500 mg) for 4 weeks, starting at least 3 days before the angioplasty. A serial IVUS study was performed post-stenting, with a 6 month follow up period. Both the stent (SA) and lumen areas (LA) were measured, and the stent (SV), lumen (LV) and intimal hyperplasia volumes (IHV) were calculated using Simpson's rule. RESULTS: The reference (RD), pre minimal luminal (MLD) and post minimal luminal diameters, as measured by quantitative coronary angiographic analysis (QCA), were not different between the two groups. Using serial IVUS measurements, SV and LV were not different between the two groups. Also, the IHV was not different between the two groups (51.9+/-26.1 and 61.3+/-25.3 mm3, respectively, p=NS). CONCLUSION: Trapidil failed to reduce intimal hyperplasia following coronary stenting compared with the controls.

ABSTRACT

BACKGROUND AND OBJECTIVES: A cutting balloon (CB) is a balloon catheter with 3 or 4 metal blades on its surface used for making controlled endovascular surgical incisions and promising minimal intimal injury. Some reports suggest advantages of the use of CB in the treatment of in-stent restenosis (ISR). The purpose of this study was to report the clinical experience of the use of CB for ISR. SUBJECTS AND METHODS: 28 patients were enrolled in this study. Angiographic success (defined by 40% residual stenosis), in-hospital, 30 days and 6 months clinical outcomes were evaluated. RESULTS: Angiographic success was 92.9% (26/28). The number of inflations and maximal inflation pressure were 2.8+/-0.9 and 10.1+/-1.3 ATM, respectively. The balloon/artery (B/A) ratio was 1.1+/-0.2. There was a case of stent insertion for treating type D dissection and a case of rotational atherectomy for suboptimal result after CB angioplasty. 25 cases underwent analysis through 6 months of clinical follow-up. During the 6-month clinical follow-up, 4 cases of re-PTCA were documented, while MACE during in-hospital time and the subsequent 30 days was 0%. CONCLUSION: Our experience demonstrated that CB can be performed safely and effectively in coronary ISR. Further clinical and angiographic effectiveness are warranted in a large-scale clinical trial.

ABSTRACT

BACKGROUND: Elevation in plasma homocysteine has been widely studied as an independent risk factor for atherosclerosis. And epidemiologic studies have demonstrated that the persons who take the folate and vitamin B6 have lower incidence of atherosclerotic vascular disease and lower plasma homocysteine level. But, not yet the effects of vitamin B6 and folate on the level of plasma homocysteine and brachial artery dilation on healthy subjects was not evaluated. METHODS: We evaluated the effects of 50 mg of vitamin B6 and 1 mg of folate on endothelial function, plasma homocysteine levels to one healthy postmenoausal woman and nineteen men in a randomized, double-blind, placebo-controlled, crossover design. RESULTS: In our study, supplement of vitamin B6 and folate significantly lowered plasma homocysteine level (placebo : folate =6.56 +1.55 micromol/L vs. 5.37 +1.04 micromol/L, p=.001). But, there were no statistically significant increament of flow-mediated dilation (FMD) compared to placebo (placebo : folate =5.12 +3.26% vs. 6.69 +2.60%, p=.070) and there were no significant correlation between the improvement of homocysteine level and increament of flow mediated dilation on healthy subjects. CONCLUSION: Compared to persons with absolute or relative hyper-homocysteinemia, our study did not show such favorable effects in healthy persons. So further studies must to be held to discover the effect of folate and vitamine B6 in healthy persons.

ABSTRACT

BACKGROUND AND OBJECTIVES: Primary coronary stenting has been shown to be an effective reperfusion therapy for acute myocardial infarction(AMI). However, few data exist regarding long-term follow-up. We examine the long-term clinical and angiographic outcomes after primary coronary stenting in the early setting of AMI. METHODS: Between September 1995 to October 1999, coronary stenting was attempted in 181 consecutive patients admitted with the diagnosis of AMI within 6 hours from the onset of the chest pain. Clinical events, including death, MI, coronary bypass surgery and repeat angioplasty, were recorded for 1 year. Angiogram were obtained at baseline, after stent, at 2 weeks and 6 months. RESULTS: 168 patients(92.8%) of all patients had complete 1 year clinical follow-up. In-hospital deaths occured in 5 patients(3%). One hundred five patients(62.5%) had follow-up angiography at 6.4+/-2.1 months after stent implantation and restenosis occured in 21.9%. Clinical events after 1 year included death in 6.5%, myocardial infarction in 1.2%, bypass surgery in 1.8% and repeat angioplasty in 7.7%. Freedom from any adverse cardiac event at 1 year was 82.2%. CONCLUSION: Primary stenting is safe and feasible in patients of AMI, even in large thrombus containing lesion and results in excellent long-term outcomes.

ABSTRACT

The provocation test of variant angina are known as ergonovine test, hyperventilation, acetylcholine, exercise and cold pressor test, but beta-blocker provocation test has not been reported as a case. So, this paper reports on the diagnosis of variant angina by beta-blocker provocation test and the case of subendocardial infarcion induced by this test. This study reports with literature and investigation about the following case : A 45-year-old man with a history of recurrent episode of typical angina on the early morning for the past 20 days. He was administrated beta-blocker given by oral route, and on the next morning there was chest pain as same degree as before, Holter EKG displayed ST segment elevation and ventricular tachycardia. It was confirmed focal spasm on coronary angiography, ST segment elevation on EKG, and newly developed hypokinesia on left ventriculogram and followed-up echocardiagraphy. When the chest pain is absent, EGK was normal. And we confirmed that elevation of cardiac enzyme was absent as a result of serial follow up study.

ABSTRACT

According to Moertel's classification, synchronous multiple gastric cancer is eonsidered to be a sort of multiple primary cancer, The clinical signifieance of multiplicity in gastric cancer was its location relative to the resection line. Compared with patients with single gastric cancer, multiple gastric cancer were more frequently found among the older men, and they were more commonly found in early gastric cancer. The frequency of multifocality in gastric cancer is 2.2-9% in the world literature reports and is increasing recently, with advance in the diagnostic method of gastric cancer. However, synchronous multiple gastric cancer which has more than four foci is rare. In Korea, there has been only one case reported about quadruple gaatric cancer. Recently, we experienced a case of a 58-year-old male patient with synchronously developed-quadruple gastric cancer on the body of stomach, for whom radical total gastrectomy and esophagojejunostomy was done. All of them were moderately differentiated adenocarcinoma. The mapping about four lesions showed that Borrmanin type III AGC extending to the serosa was placed on the posterior wall of higher body; EGC IIc invading the submucosa, the anterior wall of mid body, EGC III confined to the mucosa, the lesser curvature side of mid to lower body; EGC III localizing to the mucosa, the posterior wall of lower body. So we reported this case with a review of literatures.

ABSTRACT

Salmonellosis is one of communicable disease and still occur in sporadic in Korea frequently. They are four main clinical manifestations in salmonellosis. They are gastroenteritis, typhoidal or septisemia syndrome, focal manifestation and carrier state. Among them, focal manifestation is rarely seen. Saphra, et al. reported that localized salmonella infection is about 5%. Localized salmonella infection frequently occur during salmonella bacteremia, but may also occur with enteric fever or gastroenteritis. Gray, et al reported 3390 cases of minor gunshot wound infection that bacterial isolates from infected wounds consisted of Staphylococcus aureus(90%), Streptococcus sp.(6%), and mixed organisms(4%). Incresed host susceptibility to infection secondary to lowered resistance due to debilitating disease is an important determinant of Salmonella infection. Since salmonella is seldom suspected as a cause of soft tissue infections,there is usually a dangerous delay in the institution of appropriate antimicrobial therapy and isolation procedure. We experienced one case of subcutaneous salmonella abscess developed on gunshot wound area in lung cancer patient, which was confirmed by pus culture.

ABSTRACT

Double primary cancer of the stomach and esophagus has been revealed a very low incidence in the world except Japan and reported only 6 cases in Korea. Furthermore, it is difficult to manage this type of double cancer because esophageal cancer has a biologic tendency to early metastasis. This paper is concerned with a case of double primary cancer, which we have synchroniously confi~rmed esophageal squamous cell carcinoma and gastric adenocarcinoma with gastrofiberscopic biopsy, and then treated them by radical resec tion and systemic chemotherapy.

ABSTRACT

Hemorrhage into a pancreatic pseudocyst is a rare, but increasingly recognized as a cause of massive gastrointestial bleeding. Bleeding pseudocysts may rupture into the stomach, duodenum, common bile duct, and splenic vein, or can be decompressed via the duct of Wirsung. Also it will result in upper gastrointestinal bleeding. This represents a life-threatening and frequently unrecognized complication of pancreatic disease. Proper diagnostic workup and prompt surgical management afford the patient the best chance for survival. We report a patient with pseudocyst bleeding into the gastrointestinal tract via the duct of Wirsung and discuss the current diagnostic and therapeutic approach.

ABSTRACT

Primary small cell neuroendocrine carcinoma in stomach is known to be very rare and only the twelve cases have been reported in the English literature. This tumor appears to be analogous to small cell carcinoma and carcinoid tumors of the lung, and is characterized by a very aggressive clinical course. Recently, we have experienced a 68-year-old man with primary small cell neuroendocrine carcinoma in the stomach, which had liver metastasis and peritoneal seeding. A positive Grimelius stain was present and immunohistochemical studies revealed positivity for neuron-specific enolase in the tumor. For its rarity, we report this case with review of literatures.
