ABSTRACT
Brugada syndrome is characterized by sudden cardiac death associated with ventricular tachyarrhythmia in patients without structural heart disease. We recently observed a case of concealed Brugada ECG pattern, which appeared after oral propafenone administration for atrial fibrillation. A 34-year-old male patient who experienced syncope was admitted to the emergency department with acute atrial fibrillation (AF). Three hundred milligrams of propafenone that were administered to convert AF to sinus rhythm unmasked the Brugada ECG pattern that had remained concealed. The patient showed a type 1 Brugada ECG pattern after taking propafenone.

BACKGROUND AND OBJECTIVES: It has been demonstrated that the anomalous origin of coronary arteries (AOCA) are generally asymptomatic and rare diseases. However, some cases can cause severe life threatening events. To detect these anomalies, coronary angiographies and autopsies were used to detect coronary artery anomalies, but these procedures have limitations because of their invasiveness. The new device, Multidetector Computed Tomography (MDCT), now replaces the method of choice for detecting coronary anomalies. The prevalence of these anomalies in Korea has not been studied yet. This present analysis attempted to determine the prevalence of AOCA in Korean men by MDCT. SUBJECTS AND METHODS: 1582 Korean male police officers underwent coronary MDCT for their health screening voluntarily. After reconstruction of CT images, we could confirm coronary artery anomalies. RESULTS: The prevalence of AOCA in Korean men was 1.14% (18 out of 1582 cases). The most common abnormality (11 cases, 0.70%) was the origin of the coronary artery. Anomalies of the coronary artery end point were observed in 5 cases (0.32%). The anomalous location of coronary ostium on the aortic root was observed in 1 case (0.06%). An anomalous collateral vessel was observed in 1 case (0.06%). CONCLUSION: The prevalence of coronary artery anomalies in Korean men was 1.14%. Coronary CT is a safe and noninvasive modality for detecting coronary anomalies.

A 36-year-old male patient with no remarkable medical history was admitted to our hospital for a health check up. On chest radiography, bilateral aortic notches at the level of aortic arch were shown suggesting aortic arch anomaly without any clinical symptoms. Two aortic arches were almost same-in-size on suprasternal view of transthoracic echocardiography. In addition, multidetector computed tomography showed balanced type double aortic arch forming a complete vascular ring which encircled the trachea and esophagus. The trachea was slightly compressed by the vascular ring whereas the esophagus was intact. Nevertheless, the pulmonary function test was normal. The patient was discharged from hospital with instructions for periodic follow-up.

Approximately 5% of patients infected with Herpes zoster experience motor complications, such as muscle atrophy or paresis, caused by motor neuron involvement. The majority of paretic cases are associated with involvement of cranial nerves or of spinal nerves that innervate the muscles of extremities. We report the case of an 82-year-old female patient with cutaneous Herpes zoster involving the T10-11 sensory dermatomes, complicated by ipsilateral abdominal protrusion. Electromyography on the left external oblique muscle revealed marked denervation potentials, implying motor neuron involvement. One month after the onset of abdominal protrusion, the patient's motor symptoms markedly improved. Clinicians should consider the possibility of motor neuron involvement with Herpes zoster, even in cases of zoster involving thoracic branches of spinal nerves.

BACKGROUND: Observation on the hemodialysis treatment; whether there are any different effects on mortality rate, side effects, or effectiveness of the treatment depending on patients' age. METHODS: Chronic renal failure patients who started hemodialysis treatment between 2002 and 2003 were separated in two groups, 33 patients of 60 and older and 76 patients under 60. We investigated mortality rate difference, A-V shunt re-operation, and total protein and albumin level. Also, comparing and analyzing the urea reduction ratio, we examined whether effectiveness is different depending on the patients' age. RESULTS: The 3 year survivor rate of patients who initially started hemodialysis treatment over 60 was 66.7%, and that of the patients under 60 resulted as 73.1%. The average total protein lefel for over 60 was 6.48g/dL and for under 60 was 6.80g/dL, and albumin for over 60 was 3.15g/dL and under 60 was 3.46g/dL. We identified that the patients who repeated shunt operation in over 60 group was 4(12%) and in under 60 group was 4(5.2%). Effectiveness of the treatment, Urea Reduction Ratio(URR), for both groups was 71%. CONCLUSION: The 3 year survivor rate of patients who initially started hemodialysis treatment over 60 was lower than the control group, but considering the remaining life expectancy, it seems to be no significant difference between the groups; and the treatment effectiveness was same in both groups.

BACKGROUND: Recently, many Korean people travel abroad where malaria is prevalent. However, in Korea, relatively little is known about compliance of chemoprophylaxis against malaria. This study was performed to determine the factors influencing compliance of chemoprophylaxis against malaria in Korean travelers. MATERIALS AND METHODS: Face to face interview, telephone interview and e-mail correspondence were performed to 241 people who were prescribed with atovaquone-proguanil at the international travelers' clinic of National Medical Center between February 2007 and October 2007. RESULTS: Total of 55 people out of 235 reported one or more events of adverse reactions after chemoprophylaxis (total 76 events). However, in 38 adverse events the link between chemoprophylaxis and adverse events were very weak. Compliance of malaria chemoprophylaxis with atovaquone-proguanil was 53.9% in the study group. The predictive factors for non-compliance were package tour, travel of business affair and young age group. Conclusions: Compliance of malaria chemoprophylaxis in Korea travelers was low compared with Dutch and French studies. More efforts to increase compliance are needed, especially in travelers on package tour, business travel and people under age 40.

Kaposi sarcoma is a rare tumor originated from skin in patients with immune suppressive illness like as acquired immunodeficiency syndrome (AIDS) or organ transplantation. It may be widely disseminated internally such as digestive or respiratory organ. In Korean patients with AIDS, Kaposi sarcoma is rarely seen rather than western countries. The reason is unknown. Although few cases of Kaposi sarcoma in patients with AIDS had been described in the Korean literatures, multi-organ involved cases were extremely rare. We describe a case of old AIDS patient in whom Kaposi sarcoma had affected multi-organs including esophagus, stomach, duodenum, colon, bronchi and skin.

Systemic manifestation of tuberculosis is common, but tuberculous biliary obstruction of the pancreas and a colon adenocarcinoma with combined colonic tuberculosis is an uncommon disorder. We encountered a case of the above condition in 63-year-old male that was admitted to our hospital because of fever, diffuse abdominal pain and rigidity. Abdominal computed tomography showed biliary and pancreatic duct dilatation with left colonic wall thickening and surrounding peritoneal infiltration. Emergency segmental resection of the descending colon with intraoperative T-tube choledochostomy was performed due to the colon mass and biliary obstruction. A colonofiberoscopy was performed for low abdominal pain and hematochezia at 12 days after surgery. It showed multiple colonic ulcerations with a partial stricture. A colonic biopsy showed granulomatous inflammation with acid-fast bacilli. The cause of the biliary obstruction was also revealed as pancreatic tuberculosis by an intraoperative pancreatic and mesenteric biopsy. The patient improved after antituberculous treatment and the patient has been in good health until the last outpatient follow-up visit.

BACKGROUND AND OBJECTIVES: Metabolic syndrome and high sensitivity C-reactive protein (hs-CRP) are known to be strong predictors of coronary atherosclerosis. Even though there have been many observations and much research concerning the association of coronary atherosclerosis with CRP and metabolic syndrome, certain problems still need to be resolved in order to produce clear mechanistic illustrations. Therefore, the correlations of metabolic syndrome, hs-CRP and the severity of coronary atherosclerosis were evaluated herein. SUBJECTS AND METHODS: 271 patients, aged between 29 and 87, who had undergone diagnostic coronary angiograms at the National Medical Center, between January, 2004 and June, 2006 were evaluated. Coronary angiograms were performed in patients who complained of typical chest pain and had risk factors associated with coronary atherosclerosis. The correlations of metabolic syndrome, hs-CRP and coronary atherosclerosis were analyzed in these patients. RESULTS: Positive relationships were found between the metabolic syndrome risk factor clustering and an increased level of hs-CRP (p<0.01). The severity of coronary atherosclerosis increased with the increasing number of metabolic syndrome risk factors. As metabolic syndrome risk factor clustering increased, the quantity of 1, 2 and 3 vessel diseases also increased (Odd ratios 1.61, 1.83 and 2.50; p=0.001, <0.001 and <0.001, respectively). In contrast to metabolic syndrome risk factor clustering, no definite relationship between the hs-CRP level and the severity of coronary atherosclerosis was observed. CONCLUSION: The more metabolic syndrome risk factors clustered, the greater the severity of coronary atherosclerosis. The extension of coronary atherosclerosis maybe predicted using evaluation of metabolic syndrome risk factor clustering in patients with angina.
