1.Comparison of Long-term Complication of Malignant Biliary Obstruction after Percutaneous Transhepatic Biliary Drainage Versus Metallic Biliary Drainage.
Kosin Medical Journal 2011;26(1):30-35
OBJECTIVES: Several advances in the diagnosis, therapy and palliation of patients affected by malignant biliary obstruction have occurred during the last decades. Unresectable malignant biliary obstruction has usually been treated by percutaneous transhepatic biliary drainage (PTBD) versus metallic biliary drainage (MBD). The optimal management of complications after biliary drainage is still an unresolved problem. To compare the complications of malignant biliary obstruction after PTBD and MBD. METHODS: We enrolled 51 patients of malignant biliary obstruction after biliary drainage. The clinical characteristics and complications of each groups were assessed and compared. RESULTS: The complications after biliary drainage of MBD are lower than those of PTBD (59.1% vs 82.8%, P = 0.06, respectively). Patients with PTBD tended to have a shorter event of complication time compared to MBD patients (2.9 months vs 7.1 months, P < 0.01). Patients with older age in PTBD tended to have a longer event of complication time compared to younger patients (4.6 months vs 2.3 months, P < 0.01). CONCLUSIONS: The method of biliary drainage in malignant biliary obstruction have statistically significant impact on the complication time. The clinical efficacy of metallic stent in patients with malignant biliary obstruction is better than that of PTBD.

In an attempt to define quantitatively the relation between left atrial size and atrial fibrillation, echocardiography was used to study 58 patients with mitral stenosis and sinus rhythm, 22 patients with mitral stenosis and newly appeared atrial fibrillation, 62 patients with mitral stenosis and atrial fibrillation, 14 patients with sinus rhythm who undergone mitral valve replacement, 18 patients with atrial fibrillation who undergone mitral valve replacement,17 patients with idiopathic atrial fibrillation and 22 control persons. In all groups of mitral stenosis, atrial fibrillation was rare when left atrial dimension was below 40mm but common when this dimension exceeded 40 mm. When left atrial dimension exceeded 50 mm, sinus rhythm was rare even in patients who undergone mitral replacement operation. These data suggest that left atrial size is an important factor in the development of atrial fibrillation. To reduce the risk of systemic embolism complicating atrial fibrillation and to reduce the need of long term anticoagulant therapy postoperatively, the left atrial dimension should be followed closely for the patients with mitral stenosis.

PURPOSE: To evaluate the patterns of pseudo-lesions present on spiral CT hepatic arteriography (CTHA). MATERIALS AND METHODS: One hundred and seventy five patients (161 men and 14 women, aged 15-70 years [mean, 52 years]) who underwent spiral CTHA for the detection of hepatic lesions were retrospectively reviewed.Pseudo-lesion type was determined by comparing hyperattenuating lesions on CTHA with the findings of ultrasonography, conventional or multi-phase CT, Lipiodol CT, angiography, CT arterial portography(CTAP), and follow-up of spiral CTHA. Pseudo-lesions were classified according to site, size and shape. RESULTS: A total of 77 pseudo-lesions were found in 56 of the 175 patients(32.6%), and were classified into the following types :peritumoral(n=18), segment I(n=3), segment IV(n=3), gallbladder fossa (n=13), subsegmental (n=3), subcapsular(n=13), straight line sign (n=10), arterioportal shunt (n=13), and technical error (n=1). Fifteen of 77 pseudo-lesions(19.5%) showed hyperattenuation on CTHA and iso attenuation on CTAP, in contrast to adjacent liverparenchyma. CONCLUSION: In patients with hepatic mass, it is very important to understand the characteristicsite, shape and size of pseudo-lesions for the correct interpretation of CT and subsequent management of thepatient.

BACKGROUND: The multifactorial hypothesis is proposed as a working hypothesis which encompass both the genetic and environmental factors known to participate in the etiology of congenital heart anomalies. So, at the moment, it is believed that avoidance of suspected environmental factors in early pregenancy is most certain preventive measure of congenital heart anomalies. This study has been undertaken in order to find the possible environmental risk factors for congenital heart anomalies in Korea. METHOD: A total of 320 mothers of infants with congenital heart anomalies diagnosed at Seoul National University Hospital were included in this study as case group. And 413 mothers of healthy infants, who visited well baby clinic at the hospital during the same period of 2 years from 1987, comprised the control group. Data related to environmental risk factors including drug use during the first trimester of pregnancy, any other confounders were collected by direct interview using questionmaires. RESULT: There were positive associations for lower educational level of mother, indoor smoking habit of father, number of pregnancy, and of experience of previous abortion of mother, and multiple(or twin) birth. Relative risk estimates for the first trimester exposure to anti-emetics and herb medicine were 2.1(p<0.006) and 1.4(p<0.044), respectively. Data showed a positive association between anti-inflammatory drug exposure and congenital anomalies of pulmonary valve(OR=22.7, p<0.01), and between anti-histamine exposure and coarctation of aorata(OR=12.7, p<0.017). CONCLUSION: Environmental factors such as smoking habit of father, certain drugs used in early pregnancy, plays a role in the etiology of congenital heart anomlaies. Further studies, designed to focus on specific drug and to differentiate the effect of the suspected drug and to differentiate the effect of the suspected drug form that of the underlying conditions prompting its use, should be called upon.

BACKGROUND: Trichorhinophalangeal syndrome (TRPS) patients tend to have alopecia that appears to be androgenetic, and this genetic model might give clues to the pathogenesis of hair loss or hair morphogenesis. OBJECTIVE: This study was conducted to identify additional genetic evidence of TRPS and hair morphogenesis from a TRPS patient. METHODS: From one TRPS type I patient, we extracted RNA and profiled whole transcriptome in non-balding and balding scalp areas using high-throughput RNA sequencing. RESULTS: We found a total of 26,320 genes, which comprised 14,892 known genes with new isoforms and 4,883 novel genes from the non-balding and balding areas. Among these, a total of 1,242 genes showed different expression in the two scalp areas (p<0.05 and log2 fold-change >0). Several genes related to the skin and hair, alopecia, and the TRPS1 gene were validated by qRT-PCR. Twelve of 15 genes (KRT6C, KRTAP3-1, MKI67, GPRC5D, TYRP1, DSC1, PMEL, WIF1, SOX21, TINAG, PTGDS, and TRPS1) were down-regulated (10 genes: p<0.01; SOX21 and PTGDS: p>0.05), and the three other genes (HBA2, GAL, and DES) were up-regulated (p<0.01) in the balding scalp. Many genes related to keratin and hair development were down-regulated in the balding scalp of the TRPS type I patient. In particular, the TRPS1 gene might be related to androgen metabolism and hair morphogenesis. CONCLUSION: Our result could suggest a novel perspective and evidence to support further study of TRPS and hair morphogenesis.

BACKGROUND/AIMS: Viral breakthrough has been considered a major limitation of lamivudine in the treatment of hepatitis B virus related chronic liver disease. Its clinical meaning has not been thoroughly assessed. METHODS: 64 patients who showed viral breakthrough during lamivudine treatment were retrospectively reviewed. We evaluated the rate of HBeAg seroconversion and hepatic decompensation after viral breakthrough. RESULTS: After viral breakthrough, serum alanine transaminase (ALT) elevation more than 1.2X upper limit of normal (ULN) was noticed in 40 patients (62.5%). Acute flare (serum ALT elevation >X5 ULN, or serum bilirubin >3 mg/dL) occured in 15 patients (23.4%). During the period of follow up (15.0 +/- 9.7 months; range, 0-31 months) since viral breakthrough, decreased serum HBV-DNA level to below the detection limit and serum ALT normalization was seen in 15 patients (23.4%). HBeAg seroconversion was noticed in 7 (13.7%) of a total of 51 HBeAg positive patients at base line; in 4 (15.4%) of 26 patients with non-hepatic failure (chronic hepatitis or Child-Pugh class A liver cirrhosis) at base line; and in 2 (40.0%) of 5 patients with non-hepatic failure at base line and acute flare after viral breakthrough. During this period, terminal hepatic decompensation (Child-Pugh class C) or death was noticed in 9 (90.0%) of 10 patients who had hepatic decompensation (Child-Pugh class B or C) at baseline and acute flare after viral breakthrough. CONCLUSIONS: Acute flare after viral breakthrough seemed to continue during HBeAg seroconversion and rarely developed into terminal hepatic decompensation or death in patients with non-hepatic decompensation at baseline. Its incidence is not only high but lethal to most patients with hepatic decompensation at baseline.

We observed the gastric varices in l89 variceal patients with liver cirrhosis and in 129 patients with UGI bleeding by endoscopy. Gastric varices was found in 27 cases(14.2%) amoag 189 variceal cases. There was variceal bleeding in 74 cases(57.4%) beieg the toy cause of UGI: bleeding among l29 cases with UGI bleeding and 6(4.7%) had endoscopically proved gastric Variceal bleeding. Cardiac and fundic varices were observed in l8 and 12 cases, respectively end 12 cases of cardiac varices were mainly observed on the lesser curvature side. The incidence of isolated gastric varices being 30 % amoag gastric varices was far less than that of esophagogastric varices. There was no significant relations between the severity of liver cirrhosis and the kinds of varices These results suggest that gastric varices are not infrequent cause of UGI bleeding cases. Therefore all must have attention in gastric intestinal fiberscopic examination in portal hypertensive patients.

Transarterial chemoembolization (TACE) is a common treatment for unresectable hepatocellular carcinoma (HCC). The most common complications after TACE are non-specific symptoms called post-embolization syndrome, such as abdominal pain or fever. Rare complications, such as liver failure, liver abscess, sepsis, pulmonary embolism, cholecystitis, can also occur. On the other hand, gallbladder perforation is quite rare. This paper reports a case of gallbladder perforation following TACE. A 76-year-old male with a single 9-cm-sized HCC underwent TACE. Five days after TACE, he developed persistent right upper quadrant pain and ileus. An abdomen CT scan confirmed gallbladder perforation with bile in the right paracolic gutter and pelvic cavity. Percutaneous transhepatic gallbladder drainage was performed with the intravenous administration of antibiotics. After 1 month, the patient underwent right hemihepatectomy and cholecystectomy. Physicians should consider the possibility of gallbladder perforation, which is a rare complication after TACE, when unexplained abdominal pain persists.

Microcopic polyangiitis (MPA) is a systemic disorder affecting small vessels. In MPA, the central nervous system involvements have rarely been reported. We experienced a case of MPA with subdural effusion and pachymeningitis in a 50-year-old woman. The diagnosis of MPA was made by the presence of mononeuritis multiplex, hematuria, pachymeningitis, and p-ANCA seropositivity in this patient. Subdural effusion was of exudates and an active suppurative inflammation was observed on the dural biopsy.

PURPOSE: A retrospective study was performed to find any indicator to predict the difficulty of percutaneous transhepatic biliary drainage(PTBD) before the procedure and to evaluate correlationship between the chronological change of fluoroscopic time and the operator's experience. MATERIALS AND METHODS: The materials included the consecutive 138 cases of PTBD of 120 patients with obstructive jaundice. Under the presumption that the difficulty of procedure would be reflected on fluoroscopic time, the correlation between fluoroscopic time and eight factors(i. e. ;sex, age, disease, approach, degree of IHD dilatation, total bilirubin, alkaline phosphatase, and operator) were analysed. Also chronological change of fluoroscopic time in three operators, who performed more than 25 procedures, were evaluated. RESULTS: Statistically significant factors were operator (P=0.000), sex (P:0.028), approach(P=0.048), and total billrubin (P=0.021). Good correlation between the chronological change of fluoroscopic time and the operator's experience was found. CONCLUSION: The significant factors could be used as an indicator to predict the difficulty before PTBD procedure. The chronological change of fluoroscopic time could be used as an indirect estimate in the stabilization of the operator fechnigue.
