摘要

OBJECTIVE: Studies have presented conflicting results regarding the accuracy of ultrasonography (US) for diagnosing portal hypertension (PH). We sought to identify evidence in the literature regarding the accuracy of US for assessing PH in patients with liver cirrhosis. MATERIALS AND METHODS: We conducted a systematic review by searching databases, including MEDLINE, EMBASE, and the Cochrane Library, for relevant studies. RESULTS: A total of 14 studies met our inclusion criteria. The US indices were obtained in the portal vein (n = 9), hepatic artery (n = 6), hepatic vein (HV) (n = 4) and other vessels. Using hepatic venous pressure gradient (HVPG) as the reference, the sensitivity (Se) and specificity (Sp) of the portal venous indices were 69-88% and 67-75%, respectively. The correlation coefficients between HVPG and the portal venous indices were approximately 0.296-0.8. No studies assess the Se and Sp of the hepatic arterial indices. The correlation between HVPG and the hepatic arterial indices ranged from 0.01 to 0.83. The Se and Sp of the hepatic venous indices were 75.9-77.8% and 81.8-100%, respectively. In particular, the Se and Sp of HV arrival time for clinically significant PH were 92.7% and 86.7%, respectively. A statistically significant correlation between HVPG and the hepatic venous indices was observed (0.545-0.649). CONCLUSION: Some US indices, such as HV, exhibited an increased accuracy for diagnosing PH. These indices may be useful in clinical practice for the detection of significant PH.

摘要

Tetrahydrobiopterin (BH4) is an essential cofactor in NO synthesis by endothelial nitric oxide synthase (eNOS) enzymes. It has been previously suggested that reduced intrahepatic BH4 results in a decrease in intrahepatic NO and contributes to increased hepatic vascular resistance and portal pressure in animal models of cirrhosis. The main aim of the present study was to evaluate the relationship between BH4 and portal hypertension (PHT). One hundred ninety-three consecutive patients with chronic liver disease were included in the study. Liver biopsy, measurement of BH4 and hepatic venous pressure gradient (HVPG) were performed. Hepatic fibrosis was classified using the Laennec fibrosis scoring system. BH4 levels were determined in homogenized liver tissues of patients using a high performance liquid chromatography (HPLC) system. Statistical analysis was performed to evaluate the relationship between BH4 and HVPG, grade of hepatic fibrosis, clinical stage of cirrhosis, Child-Pugh class. A positive relationship between HVPG and hepatic fibrosis grade, clinical stage of cirrhosis and Child-Pugh class was observed. However, the BH4 level showed no significant correlation with HVPG or clinical features of cirrhosis. BH4 concentration in liver tissue has little relation to the severity of portal hypertension in patients with chronic liver disease.

摘要

BACKGROUND/AIMS: Liver stiffness measurement (LSM) has been proposed as a non-invasive method for estimating the severity of fibrosis and the complications of cirrhosis. Measurement of the hepatic venous pressure gradient (HVPG) is the gold standard for assessing the presence of portal hypertension, but its invasiveness limits its clinical application. In this study we evaluated the relationship between LSM and HVPG, and the predictive value of LSM for clinically significant portal hypertension (CSPH) and severe portal hypertension in cirrhosis. METHODS: LSM was performed with transient elastography in 59 consecutive cirrhotic patients who underwent hemodynamic HVPG investigations. CSPH and severe portal hypertension were defined as HVPG > or =10 and > or =12 mmHg, respectively. Linear regression analysis was performed to evaluate the relationship between LSM and HVPG. Diagnostic values were analyzed based on receiver operating characteristic (ROC) curves. RESULTS: A strong positive correlation between LSM and HVPG was observed in the overall population (r2=0.496, P or =10 mmHg) was 0.851, and the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for an LSM cutoff value of 21.95 kPa were 82.5%, 73.7%, 86.8%, and 66.7%, respectively. The AUROC at prediction of severe portal hypertension (HVPG > or =12 mmHg) was 0.877, and the sensitivity, specificity, PPV, and NPV at LSM cutoff value of 24.25 kPa were 82.9%, 70.8%, 80.6%, and 73.9%, respectively. CONCLUSIONS: LSM exhibited a significant correlation with HVPG in patients with cirrhosis. LSM could be a non-invasive method for predicting CSPH and severe portal hypertension in Korean patients with liver cirrhosis.

摘要

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) during severe acute respiratory failure helps to recover the pulmonary function. This study evaluated our experience with veno-venous ECMO in adult patients with acute respiratory failure. METHODS: From January 2007 to July 2009, ECMO was used on 54 patients. Of these 54 patients, 7 were placed on veno-venous ECMO for acute respiratory failure. The indications of ECMO were based on the lung dysfunction measured as a PaO2/FiO2 ratio <100 mm Hg on FiO2 of 1.0, or an arterial blood gas pH <7.25 due to hypercapnia despite the optimal treatment. EBS(R), Bio-pump(R), and Centrifugal Rotaflow pump(R) were used and all cannulations were performed percutaneously via both femoral veins. When the lung function was improved, an attempt was made to wean on ECMO at moderate ventilator settings followed by decannulation. RESULTS: Five of the 7 patients were male and the mean age was 46.3+/-18.3. The causes of acute respiratory failure were 3 cases of pneumonia, 2 near-drownings, 1 pulmonary hemorrhage due to acute hepatic failure and 1 mercury vapor poisoning. The mean support time of ECMO was 17.3+/-13.7 days. Of the 7 patients implanted with ECMO, 5 patients (71%) were weaned off ECMO and 3 patients (43%) survived to hospital discharge after a mean 89.6 hospital days. CONCLUSION: The early use of ECMO for acute respiratory failure in adults due to any cause is a good therapeutic option for those unresponsive to the optimal conventional treatments.

摘要

A 63-year-old woman was admitted due to right upper quadrant abdominal pain. She was going through hemodialysis due to end stage renal disease and taking calcium polystyrene sulfonate orally and rectally due to hyperkalemia. Colonoscopy showed a circular ulcerative mass on the proximal ascending colon. Biopsy specimen from the mass showed inflammation and necrotic debris. It also revealed basophilic angulated crystals which were adherent to the ulcer bed and normal mucosa. These crystals were morphologically consistent with calcium polystyrene sulfonate. She was diagnosed with calcium polystyrene phosphate induced colonic necrosis and improved with conservative treatment.

摘要

It is essential during extracorporeal membrane oxygenation (ECMO) to extend the activated clotting time (ACT) using anticoagulants to prevent blood clot formation. Traditionally, heparin has been used as an anticoagulant during ECMO. Hemorrhaging due to systemic heparinization is considered a major complication of ECMO. A 48-year-old man was admitted due to cardiogenic shock with acute myocardial infarction. ECMO was instituted because of recurrent ventricular tachycardia and refractory shock. We used nafamostat mesilate (Futhan) as an anticoagulant to reduce hemorrhagic complications. The total bypass time was 153 h. The average dose of nafamostat mesilate was 2.64+/-1.11 mg/kg/h; the average ACT was 128.68+/-21.24 seconds. Only a few units were transfused, and there was no oxygenator failure or hemorrhagic complications. Thus, nafamostat mesilate may reduce the need for transfusions and hemorrhagic complications during ECMO.

摘要

BACKGROUND: Tsutsugamushi, leptospirosis and hemorrhagic fever with renal syndrome (HFRS) are the prevalent diseases among the acute febrile illnesses in Korea. Pulmonary involvement in the patients with these diseases remains poorly recognized in endemic regions, and this is despite reports of recent outbreaks and epidemic episodes. Pulmonary involvement and a higher CRP level as clinical manifestations show a more severe form of infection. The aim of this study is to analyze the correlation of pulmonary involvement and the CRP level in patients with acute febrile illnesses. METHODS: We retrospectively reviewed the clinical records of 105 patients who were diagnosed with tsutsugamushi, HFRS and leptospirosis from January 2002 to May 2008 in Chuncheon Sacred Heart Hospital. The radiographic images were retrospectively analyzed by two radiologists. We analyzed the pulmonary complications of the patients with these febrile diseases and we checked the CRP level at admission. RESULTS: The study included 105 patients who were diagnosed with febrile diseases. Of these patients, 32 patients had hantaan, 10 patients had leptospirosis and 63 patients had tsutsugamushi disease. 42 (40%) patients had pulmonary complications, 20 patients had pulmonary edema, 20 patients had pleural effusion and 2 patients had interstitial pneumonitis. The patients with pulmonary involvement showed a more severe form of infection and a higher CRP level than that of those patients without pulmonary involvement (p=0.0073). CONCLUSION: Pulmonary involvement in patients with acute febrile diseases might be correlated with a higher CRP level. Identification of this factor on admission might provide useful selection criteria for the patients who need early intensive care.

摘要

BACKGROUND/AIMS: This study compared the prognostic values of the Model for End-stage Liver Disease (MELD) and the hepatic venous pressure gradient (HVPG) in the prediction of death within 3 and 12 months in patients with decompensated liver cirrhosis. METHODS: We used data from 136 consecutive patients with decompensated cirrhosis who underwent HVPG between January 2006 and June 2008. Cox regression analysis was used to investigate the independent relationships with death of MELD and HVPG. The prognostic accuracies of MELD and HVPG were analyzed by calculating the area under the receiver operating characteristic curve (AUROC) for the occurrence of death within 3 and 12 months. RESULTS: Both MELD and HVPG were independent predictors of death [hazard ratio (HR)=1.11 and 1.12, respectively; 95% confidence interval (CI)=1.04~1.20 and 1.08-1.16]. Analysis of the AUROC demonstrated that the prognostic power did not differ between MELD and HVPG for predicting the 3-month survival (HR=0.76 and 0.68, respectively; 95% CI=0.62~0.89 and 0.52~0.84; P=0.22) or the 12-month survival (HR=0.72 and 0.73, 95% CI=0.61~0.83 and CI=0.61~0.84). CONCLUSIONS: Both MELD and HVPG are independent prognostic factors of death within 3 and 12 months in patients with decompensated liver cirrhosis, and their accuracies are similar. However, HVPG has a limited role in the prediction of death in decompensated cirrhosis due to its invasiveness and limited use.

摘要

BACKGROUND/AIMS: The aims of this study were to estimate the frequency of symptoms of gastroesophageal reflux disease and reflux esophagitis, to evaluate the difference in characteristics among groups subdivided by symptoms, and to compare clinical features between a reflux esophagitis group and a non reflux esophagitis group in Chuncheon City. METHODS: A total of 1,011 persons who underwent endoscopy for health check up were enrolled between July 1, 2005, and June 30, 2006. All persons were given a validated, self reported questionnaire, which inquired about the presence, frequency, and severity of typical symptoms (heartburn and acid regurgitation) and atypical symptoms. The questionnaire also inquired about smoking, alcohol intake, and Helicobacter pyroli eradication. The subjects were subdivided into typical symptomatic, atypical symptomatic, no discomfort, and asymptomatic groups. RESULTS: The prevalence of heartburn and acid regurgitation occurring at least weekly was 7.5%. Reflux esophagitis, hiatal hernia, smoking, and alcohol intake were more common in males (p<0.05). Ninety eight cases (9.7%) were endoscopically diagnosed as reflux esophagitis, and sixty nine cases (6.8%) were endoscopically suspected esophageal metaplasia (ESEM). Subjects in the symptomatic group more frequently manifested reflux esophagitis than subjects in the asymptomatic group (p<0.05). CONCLUSIONS: The presence of reflux induced symptoms is related to reflux esophagitis, but the intensity and frequency of symptoms are poor predictors of the presence or severity of endoscopic mucosal breaks.

摘要

OBJECTIVE: The aim of this study was to evaluate the correlation between the results of preoperative PAP smears and known poor prognostic factors in patients with endometrial carcinoma. METHODS: Between Jan. 2000 and Dec. 2003, preoperative evaluation of PAP smears were done in 111 patients with endometrial carcinoma who underwent surgical staging. Pathologic parameters of permanent specimens were evaluated and correlated with the results of PAP smears. chi-square-test was used for statistical analysis and p-values <0.05 was considered as statistically significant result. RESULTS: The mean age of patients was 49 years with range between 24 and 75 years old. The results of preoperative PAP smears were normal in 70 patients (57.7%), atypical glandular cells of undetermined significance (AGUS) in 22 patients (22.5%), adenocarcnoma in 19 patients (19.8%) on preoperative PAP smears. Statistically significant associations were found between preoperative PAP smears and poor histologic grade (p=0.000), depth of myometrial invasion (p=0.000), lymph-vascular space invasion (p=0.003), cervical involvement (p=0.004), adnexal involvement (p=0.024), positive peritoneal cytology (p=0.042). However, old age, poor histologic type, higher surgical staging, pelvic nodes metastasis and para-aortic lymph node metastases were not statistically significant. CONCLUSION: This study revealed glandular cell abnormalities on preoperative PAP smears in patients with endometrial carcinoma were significantly associated with poor histologic grade, deep myometrial invasion, lympho-vascular invasion, cervical involvement, adnexal involvement, positive peritoneal cytology. Therefore, the results of preoperative PAP smears could be considered as an important part of the preoperative evaluation in patients with endometrial carcinoma.

摘要

BACKGROUND: Moderate drinking has been known to be associated with a risk of reduced cardiovascular disease morbidity and mortality. The metabolic syndrome has been associated with a risk of increased cardiovascular diseases. Because drinking is considered as a risk factor of the metabolic syndrome, this study was performed to examine the association between alcohol drinking and the metabolic syndrome in Korean women. METHODS: The subjects were 262 women who visited the health promotion center of Chungnam National University Hospital for general health check-up. The metabolic syndrome was diagnosed according to the definition by the National Cholesterol Education Program Adult Treatment Panel III. The abdominal obesity guidelines for waist circumference applied the WHO Asian Pacific Guideline. The subjects were classified into nondrinking, moderate drinking (1 drink) according to their drinking amount per day. The relationship between the components of the metabolic syndrome and drinking state were investigated. The prevalence of the metabolic syndrome was compared according to the drinking state. RESULTS: The women with moderate drinking showed significantly lower levels of triglyceride than nondrinkers (P<0.05). The women with drinking showed significantly higher levels of HDL cholesterol than nondrinkers (moderate drinkers P<0.05, heavy drinkers P<0.05). Considering nondrinkers as standard, the risk of the metabolic syndrome was significantly low in women with moderate drinking (odds ratio=0.43, 95% confidence interval: 0.22~0.84, P=0.013). CONCLUSION: The results of the present study suggest that moderate drinking is related to a lower rate of the metabolic syndrome in Korean women.

摘要

OBJECTIVES: The aim of this study was to evaluate the clinicopathologic characteristics of malignant germ cell tumors of ovary. METHODS: Thirty five patients who were dignosed as malignant germ cell tumors of ovary and treated in Cheil General Hospital from January 1995 to December 2003, were retrospectively analyzed. The age, chief complaints, histologic type, tumor marker, FIGO stage, maximal tumor diameter, management, survival and future pregnancy outcome were reviewed. RESULTS: The mean age was 23.4 years (8-34) and 2 patients were premenarche. The mean follow-up period was 59.6 months (16-118). Palpable lower abdominal mass and pain were the most frequent symptoms. Preoperative CA125 were checked in 32 patients and elevated in 23 patients . The tumors were ranging from 7cm to 27cm in diameter (mean : 16.6). The site of tumors was right-sided in 17(48.6%), left-sided in 15(42.9%), and bilateral in 3(8.6%) which were dysgerminomas only. Post-surgical FIGO stage was stage I in 28 cases (80.0%), stage II in 4 cases (11.4%), and stage III in 3 cases (8.6%). Histologically, immature teratomas were found most frequently (n=14, 40.0%), followed by dysgerminoma (n=10, 28.6%), endodermal sinus tumor (n=9, 25.7%), and mixed form (n=2, 5.7%). Unilateral salpingo-oophorectomy was performed in 9, cystectomy in 4, and staging operation in 22, which included 16 patients of fertility sparing operation. Postoperative chemotherapy was administered in 30 and most were BEP except one TIP. Two patients had recurred, who were stage Ic and IIIb EST at diagnosis and expired at 59 and 16 months after first operation. Recurrence rate was 5.7% and 5-year survival rate was 94.7%. During follow-up period, 8 patients were pregnant and the results were 4 normal deliveries at term, 1 missed abortion, 1 therapeutic abortion due to acne medication, 1 H-mole and 1 current pregnant state at 20 weeks without problem. CONCLUSION: These results shows that most malignant germ cell tumors of ovary is detected in early stage and have relatively excellent survival with conservative operation and combination chemotherapy.

摘要

BACKGROUND: Parent's alcohol drinking not only influences their health but also their children. This research was designed to assess the family function of children who were affected by parent's alcohol drinking. METHODS: Questionnaire survey was performed on 208 high school students (129 males and 79 females) in Daejeon from March to April, 2005. We defined the students whose CAST (Children of Alcoholics Screening Test) score was 6 or more as children of alcoholics (COA) group. Then, we evaluated the family function by family APGAR score between the COA group and the control group. RESULTS: Among the total, 36 (27.9%) male and 27 (34.1%) female students were in COA group. There was a significant (P<0.01) negative correlation between the CAST score and the family APGAR score in all students. In boys, there was no significant correlation between the CAST score and the family APGAR score, but in girls, there was significant negative correlation (P<0.01). Mean family APGAR score of the COA group was significantly (P<0.05) lower than that of the control group in all students. In boys, there was no significant difference, but in girls, the COA group's family APGAR score was significantly lower than the control group's score (P<0.05). CONCLUSION: The high school students, especially girl students, who were affected by parent's alcohol drinking showed a lower family APGAR score. Therefore, family physicians need to evaluate the family function when encountering students similar to COA group.

OBJECTIVE: The aim of this study was to correlate histologic type with the clinico-pathologic features of endometrial carcinoma. METHODS: A retrospective review was performed of 158 patients with endometrial cancer who had treated surgically at Cheil General Hospital between Jan. 2000 and Dec. 2003. Histologic findings after operation were divided two groups (endometrioid group vs. non-endometrioid group) then compared to each other groups. Clinico-pathologic factors were reviewed, compared and statistically analyzed. RESULTS: Endometrioid group was 112 cases (70.9%) and non-endometrioid group was 46 cases (29.1%). Non-endometrioid group was mucinous; 5 (3.2%), UPSC; 6 (3.8%), clear Cell; 2 (1.3%), mixed; 32 (20.3%), adenosquamous; 1 (0.6%). Non-endometrioid group showed older (p=0.0003) and higher proportion of menopausal women (p=0.0017) than Group 1. But menopause mean age were not diffent between two group. Abnormality in Pap smear and thickness of endometrium (TVS) were not diffent between two group. Non-endometrioid group were significantly associated with higher grade (p=0.0000), deeper myometrial invasion (p=0.0030), larger tumor size (p=0.0006), Lympho-vascular invasion (p=0.0486) and higher recurrence rate (p=0.0369) CONCLUSION: This study revealed non-endometrioid group was significantly associated with older age, menopause status, advanced pathologic features at surgical staging, and high recurrence rate.

摘要

OBJECTIVE: The objective of this study was to investigate the relationship between the expression of mRNA and protein of HLA-G and other clinicopathologic prognostic factors of ovarian cancer. METHODS: 43 patients diagnosed with ovarian cancer from 1997 to 2005 and 5 patients with normal ovarian tissue (controls) were enrolled in this prospective study. The patient group all went through baseline studies with staging laparotomy and adjuvant chemotherapy. Quantitative real-time RT PCR and Western blot analysis were used in detecting the expression of mRNA and protein of HLA-G. RESULTS: The mRNA expression of HLA-G (2-delta delta Ct value) in cancer group were 1.21 (0-9), and 0.01 (0-0.02) in control group, which was statistically significant (P=0.005). The expressed protein levels did not show any difference between the cancer and control groups. There also was a significant relationship between the serum CA 125 at the time of diagnosis and the HLA-G protein levels (P=0.02). But the relationship between other clinicopathologic prognostic factors and the HLA-G protein levels were not statistically significant. CONCLUSION: Our results showed that HLA-G mRNA expression level was much higher in ovarian cancer patient group than in those of control group. Therefore HLA-G maybe play an important role in carcinogenesis of ovarian cancer. Although the protein level of HLA-G had low significance with other prognostic factors, serum CA 125 showed a statistically significant relation with protein levels of HLA-G. Further studies based on the correlation between HLA-G and survival rate are needed to support HLA-G as a prognostic factor of ovarian cancer.

摘要

OBJECTIVE: The purposes of this study were to investigate the types and the incidences of chromosomal abnormalities, and to provide an explanation for the genetic causations of recurrent spontaneous abortions in Korean population. METHODS: Cytogenetic studies were carried out in 535 couples with at least two spontaneous first trimester abortions from January 1981 to December 2003. For karyotype analysis, we used modified Moorhead method by Giemsa staining and Giemsa-Trypsin-Giemsa banding RESULTS: The overall incidence of chromosome abnormality was 32 out of 535 cases (5.98%). There were 25 cases (4.67%) of translocation and 7 cases (1.31%) of inversion. In translocation, 5 cases (0.93%) of Robertsonian translocation and 20 cases (3.74%) of reciprocal translocation were observed. In inversion, 6 cases (1.12%) of inversion of chromosome 9 and one case (0.19%) of inversion of chromosome 18 were found. CONCLUSION: In this study, overall chromosomal abnormality rate in couples with recurrent spontaneous abortions is much higher than that in the general population. So, chromosomal analysis should be offered for the prognostic information in genetic counseling such as prenatal diagnosis in couples with repetitive reproductive failure.

OBJECTIVE: For evaluation of prevention program for neonatal vertical transmission from HBsAg positive mother in Korea METHODS: From January 15th to February 15th 2003, the status of neonatal vaccination, immunoglobuline injection and breast feeding of HBsAg positive mother was evaluated by using mailed questionnaire in 848 hostpitals with more than 100 deliveries in the year of 2001. 341 out of 848 (40.2%) hospitals returned questionnaires. RESULTS: 91.9% of total hospital reported that the vaccination of hepatitis B and immunoglobulin injection was done within 12 hours after birth in more than 90% of neonate. The most commonly used vaccine type was 0-1-6 method. In case of unknown result of HBsAg/ HBsAb in mother, 84.4% of hospitals delayed immunoglobulin injection until complete report, however 63% of hospitals gave hepatitis vaccine without delay before complete result. The breast feeding of HBsAg positive mother was recommended according to the result of HBeAg in 66.3% of hospitals while 24.9% of hospitals recommend breast feeding. CONCLUSION: Most hospitals in Korea reported that vaccination of Hepatitis B and immunoglobulin injection was done within 12 hours after in over 90% of neonate whose mother was HBsAg Positive. But continuous education and careful monitoring are required for injection method and vaccination policy in neonates of mothers with unknown result of HBsAg/HBsAb of mother.

摘要

Leiomyoma of the uterus is the most common benign uterine tumor affecting 40-50% of women older than 40 years of age. The pathogenesis of uterine leiomyoma is unknown, but several studies have suggested that each leiomyoma arises from a single neoplastic cell within the smooth muscle of the myometrium. Uterine leiomyoma can be extended outside the uterus growing into the pelvic veins, and in exceptional cases, even into the lung. Even if this was first reported more than 90 years ago, the pathogenesis and treatment of benign metastasizing leiomyoma was not still established. We experienced a case of benign metastasizing leiomyoma and report with a brief review of literature.
