  • Pyogenic liver abscess with metastatic septic complications is a rare and serious infectious disease if not treated properly. Pyogenic liver abscesses are caused by bacterial, fungal, or parasitic organisms. Escherichia coli used to be the predominant causative agent, but Klebsiella pneumoniae emerged as a major cause in the 1990s. Liver abscesses are caused by hepatic invasion via many routes, such as, the biliary tree, portal vein, hepatic artery, direct extension, or penetrating trauma. Furthermore, diabetes mellitus and malignant conditions are established important risk factors of K. pneumoniae liver abscesses and of septic metastasis, and several recent studies have asserted that K. pneumoniae liver abscess might be a presentation of occult or silent colon cancer. We report a case of K. pneumoniae liver abscess, metastatic septic pulmonary embolism, and endophthalmitis associated with diabetes and advanced gastric cancer.

  • Small dense LDL(LDL III) is emerging as a major risk factor for coronary artery disease. LDL III generation is associated with high triglyceride concentration, high hepatic lipase activity, and high cholesterol ester transfer protein (CETP) levels. CETP polymorphisms have been reported to be associated with coronary artery disease. In this study, we investigated the relationship between CETP polymorphism and LDL III generation. VLDL1, VLDL2, IDL and LDL subfractions were measured in 87 normal healthy Korean subjects who had been SNP genotyped for Taq1B, I405v and A629C. We found no differences in LDL subfractions and lipoprotein composition between homozygotes for Taq1B2B2, and those for Taq1B1B1 and Taq1B1B2. There were no differences in LDL subfractions and lipoprotein composition between homozygotes for 629AA, and those for 629AC and -629CC. However, homozygotes for 405VV had a significantly lower LDL III concentration and proportion than those for 405II and 405IV. We concluded that, among the Taq1B, I405V and A629C polymorphisms, only the 1405V polymorphism was associated with the concentration and proportion of LDL III.

  • Liver CT 검사에서 간세포암과 간혈관종의 구별은 악성종양과 양성종양을 구별하여 치료방법을 결정하는 것에 있어서 중요한 검사 방법 중 하나이다. 현재 사용되는 방법은 전문의의 주관적인 해석에 의해 판독이 이루어지고 있으며, 추가적인 해석을 위해 본 연구에서는 객관적인 방법을 제시하고자 한다. 조영제 주입 후 검사시간은 조영주입전기(Pre), 동맥기(35sec), 문맥기(70sec), 지연기(180sec)로 하였다. 조영증강패턴변화(Enhancement Pattern) 에서 간세포암의 일반적인 패턴변화는 26.6% 로 관찰 되었다. 간혈관종의 일반적인 패턴변화는 16.6%로 관찰 되었다. 간세포암과 간혈관종의 HU(Hounsfield unit)값 변화를 관찰하기 위해 각각의 시간별 평균값과 표준편차를 확인한 결과 Lesion부위의 artery-portal차이가 가장 큰 것으로 나타났다. (간세포암 $19.76{\pm}23.52$, 간혈관종 $60.23{\pm}29.43$). 간세포암 에서 76.6%, 간혈관종 에서 80.0%가 일치하게 나타났다. 본 연구를 통해 HCC와 HH의 객관적 분석 지표로 HU값 을 제안하고 분석방법을 임상에 사용 한다면 진단에 도움을 줄 것이다.

  • Alagille syndrome (AGS) is a rare autosomal dominant inherited disorder, with major clinical manifestations of bile duct paucity, cholestasis, cardiovascular anomaly, ophthalmic abnormalities, butterfly vertebrae, and dysmorphic facial appearance. It is caused by heterozygous mutations in JAG1 or NOTCH of the Notch signaling pathway presenting with variable phenotypic penetrance and involving multiple organ systems. The following case report describes a unique case of a 16-year-old female with AGS who presented with the primary complaint of renovascular hypertension. She had a medical history of ventricular septal defect and polycystic ovary syndrome. The patient had a dysmorphic facial appearance including frontal bossing, bulbous tip of the nose, a pointed chin with prognathism, and deeply set eyes with mild hypertelorism. Stenoocclusive changes of both renal arteries, celiac artery, lower part of the abdominal aorta, and left intracranial artery, along with absence of the left internal carotid artery were found on examination. Whole exome sequencing was performed and revealed a pathologic mutation of JAG1, leading to the diagnosis of AGS. Reverse phenotyping detected butterfly vertebrae and normal structure and function of the liver and gallbladder. While the representative symptom of AGS in most scenarios is a hepatic problem, in this case, the presenting clinical features were the vascular anomalies. Clinical manifestations of AGS are diverse, and this case demonstrates that renovascular hypertension might be in some cases a presenting symptom of AGS.

  • Purpose: This study compared the characteristics of and the prognosis for intraperitoneal and retroperitoneal/pelvic contrast extravasation, which had been confirmed by enhanced abdominal CT scan, after blunt trauma in patients who had undergone angiographic embolization. Methods: From January 2001 to March 2009, data were retrospectively collected regarding patients who had undergone contrast extravasation (CE) on CT scanning and arterial embolization after blunt trauma. The study patient group was divided into the intraperitoneal and the retroperitoneal/pelvic groups according to the area of contrast extravasation. We reviewed the initial demographic data, the location of injury, the solid organ injury, the embolized vessel, and the clinical outcome. Results: The mean age of the study subjects was $40.2{\pm}2.6$ years old, and there were 24 male patients. The intraperitoneal group included 10 patients, and retroperitoneal/pelvic group was comprised of 17 patients. The amount of transfusion from presentation to intervention and during the first 24 hours was greater in the retroperitoneal/pelvic group than in the intraperitoneal group. The intraperitoneal group showed a higher frequency and severity of liver injury than the retroperitoneal/pelvic group. Angiography revealed that the hepatic artery (n=4) was the most frequently embolized vessel in the intraperitoneal group, while the internal iliac artery (n=6), followed by the renal artery (n=4), internal pudendal artery (n=3), and the gluteal artery (n=2), were the most frequently injured vessels in the retroperitoneal/pelvic group. Conclusion: In patients with intra-abdominal contrast extravasation found on CT scanning and arterial embolization after blunt trauma, the need for transfusion was less in the intra-abdominal group than in the retroperitoneal/pelvic group. Liver injury was also more frequent and severe in the intraperitoneal group than in the retroperitoneal/pelvic group.

  • Hemorrhage into the biliary system as a consequence of injury to the liver has been called "traumatic hemobilia," a term introduced by Sandblom in 1948. The source of gastrointestinal hemorrhage has been frequently misinterpreted, resulting in inadequate or inappropriate treatment, often with catastrophic results and needless fatalities. It is now being diagnosed with increasing frequency, due to more widespread knowledge of the syndrome and improved diagnostic means. we experienced 2 cases of hemobilia following blunt chest trauma, One patient had! multiple rib fractures on right chest by car traffic accident and 13 days later, suddenly massive melena was developed with nausea, vomiting, jaundice and severe pain on right upper quadrant. And so, he had operated on the ligation of Rt. hepatic artery and partial right hepatectomy for a traumatic hemobilia. The other one also revealed similar symptoms 20 days later following blunt chest injury by falling down accident. However, uneventful recovery was seen without any of surgical intervention in this case.

  • Pulmonary arteriovenous fistula can be either congenital or acquired. The vast majority are congenital, and about 60% have been associated with hereditary hemorrhagic telangiectasia [Rendu-Osler-Weber disease . Secondary or acquired pulmonary arteriovenous fistula occurs with trauma, schistosomiasis, long-standing hepatic cirrhosis, metastatic carcinoma, and actinomycosis. Pulmonary hemorrhage secondary to acquired pulmonary arteriovenous fistula is a rare event associated with mortality. We have experienced 64 year-old female patient with the hemoptysis secondary to acquired pulmonary arteriovenous fistula due to the infection of pulmonary parasite. The chest PA and CT scan was showed calcified nodule to the distal portion of lateral segmental bronchus of RML. The bronchial angiogram was demonstrated slightly hypertrophied bronchial artery supplying RML bronchus and the presence of hypervascularization around the calcified nodule, rapid A-V shunting is noted by fluoroscopy. The patient was successfully treated by the right middle lobectomy.

  • Two patients with uncorrectable cyanotic cardiac anomalies underwent total cavopulmonary shunt[modified Fontan operation]. Case I was a 14 years old male with dyspnea and cyanosis after birth. Aortogram showed TGA combined with overriding of aorta, pulmonary stenosis, complete atrioventricular septal defect, interruption of inferior vena cava, and situs inversus totalis. We had performed total cavopulmonary shunt using with 16 mm Gortex Graft in single atrium to bypass the hepatic vein to pulmonary artery. Postoperatively, patient sustained low PaCO2 and low cardiac output and then expired at 19th postoperative day. The cause of death of the patient would be low cardiac output. Case II was a 6 years old female with dyspnea and cyanosis after birth. Aortogram showed tricuspid atresia[Type IIb], transposition of great arteries, atrial septal defect, ventricular septal defect and pulmonary stenosis, We had performed total cavo-pulmonary shunt using intraatrial baffle[tunnel] with Goretex patch. The postoperative course of this patient was good without event.

  • Calculational models to evaluate radiation doses resulting from the medical use of high energy beta-ray sources are presented. The radioactive sources considered are Sr-90/Y-90 used as ophthalmic applicator, Re-188 used for treating restenosis of coronary artery, and Ho-166 used for treating hepatic tumors. Typical therapeutic situations which might induce relatively high radiation doses the medical person involved were considered to compute by using MCNP-4C Monte Carlo code the radiation doses. The calculation results suggest that for all of the cases considered, the evaluated radiation doses are negligible compared to the dose limits. It is also found that the effect of Bremsstrahlung radiations on the total dose is insignificant, and hence the conventional lead gown is also effective in shielding beta-rays.

  • Gallbladder injuries are rare in cases of blunt abdominal trauma and are usually associated with damage to other internal organs. If the physician does not suspect gallbladder injury and check imaging studies carefully, it may be difficult to distinguish a gallbladder injury from gallbladder stone, hematoma, or bleeding. Therefore, in order not to miss the diagnosis, the clinical findings and correlation should be confirmed. In the present case, a 60-year-old male presented to a local trauma center complaining of pain in the upper right quadrant and chest wall following a motor vehicle collision. Abdominal computed tomography (CT) showed a hepatic laceration and hematoma in the parenchyma in segments 4, 5, and 6 and active bleeding in the lumen of the gallbladder. Traumatic gallbladder injuries generally require surgery, but in this case, non-operative management was possible with cautious follow-up consisting of abdominal CT and angiography with repeated physical examinations and hemodynamic monitoring in the intensive care unit.
